Installation of the truss system of a multi-gable roof. Multi-gable roof: features and installation of the truss frame. Gable roof device

The multi-gable roof has a high structural complexity and price, therefore it is usually used as a unique architectural solution on large country houses, whose owners prefer an unusual, but original design. In addition, as a result of the arrangement, several side attics are obtained. Due to the complexity of execution, it is not possible to build such a roof with your own hands.

Definitely, without the involvement of specialists, such an undertaking will take a lot of time, effort and money.
An excellent solution for a non-standard shape of houses will be a multi-gable roof. Under this form, you can mean a house in the form of "T", or "U", or "G", as well as other, most diverse, multifaceted forms. This construction bears its name from the name "tongue", which refers to the upper part of the wall, surrounded on both sides by slopes. That is, in fact, the gable is the same pediment, only without a cornice and any other architectural elements. In simple terms, this is a bare piece of wall, possibly with a window opening.

The types of a multi-gable roof are varied, and how many gables a house has, this is how the roof will be called: three - three-gable, four - four-gable, six - six-gable, eight - eight-gable. Houses of round, square and rectangular - typical perimeters, can also have a multi-gable roof as an ending. This is the common name, as you already understood, of a roof in which there are several tongs. This is understandable, now let's deal with the constructive part for greater clarity of the origin of this type of roof.

The design of a multi-gable roof is complex in the sense that it has not only external ribs, but also internal ones, referred to as a valley. They are key nodes, as they must withstand powerful loads, so there must be a system of supports and braces under them. However, the main node, which contains the construction of multi-gable roofs, is considered to be the intersection of the ridge beams (the upper horizontal ones, to which the rafters are mated), into which, in addition, the valleys adjoin. This node is provided with stability by a vertical riser - a massive beam supporting it from below, against the ceiling.

The device of a multi-gable roof becomes more complicated at all stages of the device, starting from the flooring, the device of the “pie”, especially the waterproofing of internal corners, ending with the roofing. The heavier the roofing material of the coating, the greater the load from precipitation - the more difficult frame structure rafters, braces, props. Often, under such roofs, a dwelling is equipped ( attic floor), and this contains additional work for thermal insulation, vapor barrier, etc. However, in such roofs there is an advantage: each gable can be easily equipped with a window opening, therefore, the device window openings in the roof frame itself can be minimized or not at all.

Among roofs with straight planes of slopes, multi-gable roofs are complex types of roofs with numerous crossed slopes and internal angles between their joints. It is being built on buildings that are distinguished by a complex layout of various geometric shapes, multi-level attics and attic spaces.

A multi-gable roof is considered complex design The complexity of the design is explained by the presence in such roofs of a large number of valleys and gables, the installation of which causes specific difficulties and additional costs.

The arrangement of the valley requires especially close attention, because it is through them that streams of rain and melt water will flow in the future. Also in these places there is the greatest accumulation of snow, and therefore they must have a significant bearing capacity and tightness. Professional formation of the valley, the main vulnerable element roofing, provides reliable removal from a roof of thawed and rain waters.

Structural elements

In multi-gable roofs, the following structural elements are always and necessarily present:

gables and gable overhangs;

valleys formed when pairing forceps;

roof ridge.

Varieties of multi-gable roofs

The shape of a multi-gable roof can be very diverse and limited only by the imagination of the developer or designer. The number of tongs (gable elements with a ridge) in the roof can be from two to an unlimited number. Roof slopes can be in the form of triangles and trapezoids.

As a coating for multi-gable roofs, any roofing materials can be used, but provided that the roof frame (rafter system) is properly designed, capable of withstanding all the loads on the roof during its operation.

Advantages and disadvantages of multi-gable roofs

The multi-gable roof structure has certain advantageous characteristics. These include:

· original, unique, graceful forms of a roof;

Ideal combination with buildings of any architectural forms;

balanced rafter system;

the possibility of arranging a spacious attic and a significant increase in its usable area;

no risk of stagnant rain and melt water due to the large slope of the roof surface and the presence of grooves;

Reliability, strength, durability of the structure;

Compliance of the cost of a multi-gable roof with operational and aesthetic characteristics.

The list of shortcomings of this type of roof includes: the level of complexity of installation, the presence of a large number of valleys that complicate the process of arranging, maintaining and maintaining the roof, as well as high consumption building materials. The installation of a multi-gable roof is a labor-intensive construction work, for which it is necessary to seek the help of professional specialists. Roof installation takes longer.

Despite the serious shortcomings of a complex architectural form, the aesthetic, original, presentable appearance and performance characteristics of a multi-gable roof rightfully deserve the praise and attention of private property owners.

A multi-gable roof is arranged on houses with a complex polygonal shape of the plan. Such roofs have a greater number of valleys (inner corner) and ribs (protruding corners that form the intersection of the roof slopes), which require high qualifications when performing roofing work.

Buildings with multi-gable roofs have original design. This type of roof is considered the most popular. He came to us from the West and began to be effectively used for the construction of various buildings. A draft of the entire structure is preliminarily drawn up in a special program so that it is possible to visually evaluate appearance future home. The difference between a multi-gable roof lies in the complexity of its construction. At the same time, it will look very original, and the structure with it will be refined and unusual. Note. Houses for the construction of such a design can be of any shape and size. It is much easier to construct a roof of this type on buildings with a rectangular or square shape. Installation of a multi-gable roof is carried out not only in order to protect the building from various climatic and weather phenomena. It can be installed in attics that need additional lighting, or in houses with a complex layout.

Benefits of a multi-gable roof
Attractive appearance. The roof is massive and unusual. Her project can be anything. It all depends on the parameters of the structure and its functionality.
Durability and reliability. Such a roof is easily able to withstand significant loads on its surface and at the same time not change its original appearance. All this is provided by a balanced frame of the truss system.
Durability. The service life of the roof structure is unlimited. True, it is worth considering that the material for its construction and design plays an important role.
Practicality. Rainfall will not accumulate on the roof of this type. All thanks to the slopes, which are located at a large angle of inclination.
Efficiency. You can use the space under the roof as you wish. You can make a room there. It is for this reason that not only the house, but also the roof is preliminarily drawn up.

But despite the dignity of this roof, there are a number of disadvantages:
The complexity of the construction of the roof ... The work requires professional training, especially if they are performed independently. In order to avoid mistakes in work, it is necessary to consult with experts in this field who will tell you how to properly develop a roof project and take into account the load of roofing material on the truss system.
A large amount of waste finishing and building materials. Due to the fact that the main characteristic of a multi-gable roof is the presence of a certain number of slopes and bends, the funds for its construction will be used irrationally.
It is one of the most expensive roofs.

Multi-gable roofs are also called hip roofs. Even not every professional can cope with the construction of such a structure.

The construction of such roofs is accompanied by the formation of ventilated attics, completely isolated from all heated rooms of the house.

Four-pitched hip roofs are also difficult because their installation is associated with a large consumption of roofing materials, and after their construction, a lot of waste remains. Semi-hip roofs are formed by several slopes.

Despite the fact that such roofs look very beautiful, their projects are quite difficult to implement, as they are accompanied by the formation of valleys that require careful waterproofing work.

However, the expressive and stylish look of multi-gable roofs is worth it to make every effort during their installation.

Features of multi-gable roofs

Despite the difficulties that arise in the implementation of complex architectural forms of multi-gable roofs, they are very often used in the construction of private houses.

In fact, a multi-gable roof does not carry any functional load, but at the same time it does a tremendous job in creating the external architectural style of the building.

The simplest gable roof truss system is nothing more than a 90-degree intersection of two gable roofs.

When erecting a multi-gable roof truss system, elements such as rafters, girders, Mauerlat are used. As in any roof structure, the mauerlat is a support beam, through which loads are transferred from the rafter legs to the load-bearing walls of the house.

In addition, the mauerlat is the link between the roof structures and the walls of the structure. It is made of wooden blocks with a section of 150 by 100 mm or 150 by 150 mm and a length of about 1.5 m. For mounting rafters, as a rule, boards measuring 150 by 50 mm are used.

The rafter system is of two types: hanging and layered type. Its choice depends on the presence or absence of internal bearing walls or any other supports that replace them. Sometimes, when forming roofs with complex architectural forms, it is advisable to use both types of truss systems.

In the area of connection of gable roofs, it is recommended to install diagonal (sloping) rafters, on which in the future the sprigs, which are shortened supporting elements, will rely. Due to the fact that the rafters are exposed to sufficiently large loads during operation, it is recommended to strengthen them during installation.

In the upper part, the truss structure is connected by a ridge run, which is made of interconnected boards or timber of sufficient section. In the event that additional structural reinforcement is required, it is recommended to install intermediate runs.

After the installation of the truss system is completed, they begin laying hydro-, steam- and heat-insulating layers. Laying of materials is carried out perpendicular to the roof slopes with an overlap of at least 15 cm and mandatory gluing of the joints with a connecting tape.

After laying the waterproofing layer, the elements of the counter-lattice are mounted, for the arrangement of which bars with a section of 50 by 50 mm or boards of 32 by 100 mm are used. The installation of the lathing is carried out in accordance with the requirements of the manufacturers of the selected roofing material.
Structural features of multi-gable roofs

As mentioned earlier, multi-gable roofs are quite complex structures. Some of their fragments may consist of variations gable roof interconnected in complex architectural structures.

Stages of construction of a multi-gable roof

· Removal from the structure of all necessary measurements.

· Creation of the project.

Correct calculation of the dimensions of the rafters and all structural elements.

· Installation of Mauerlat.

· Installation of truss system.

· Laying hydro, heat and vapor barrier layers.

· Installation of counter-lattices and battens.

· Laying of roofing material and arrangement of valleys and stiffening ribs.

The choice of the slope of the roof slopes directly depends on the chosen roofing material, the climatic features of the area, the intensity of wind loads, as well as the size of the snow cover and architectural features.

The multi-gable roof has a rather complex structure, and in order for it to be reliable protection at home, it must be properly installed.

And in order for this to happen, it needs the arrangement of such elements as grooves, valleys and stiffeners, the quality of installation of which directly affects the reliability of the future roof.

Multi-gable roof - the design is quite complicated. It is distinguished by the presence of numerous intersections of slopes, at which valleys are formed, the so-called formed internal corners. The valley is considered the most unreliable element. Indeed, the maximum flows through them a large number of water, despite the fact that their slope is significantly less than that of the slopes. Snow accumulates there, increasing the load on the roof. Therefore, the valley can be considered the “weak” point of such structures. So, this roof is not only complicated in its structure, but it is also not easy to follow it.

At the junctions of the roof slopes, ribs are also formed, but, unlike the valleys, they form an external corner.

A vivid illustration of them is, for example, the place where two slopes in a quadrangular roof are connected.

The shape of the structure during the construction of this type is either polygonal, the scheme of which is presented below, or square. It can be installed in houses with a complex layout or in attics, for which it is necessary to provide special additional side lighting. For extensions of such buildings, different heights are characteristic.

However, neither this nor the significant cost, because the complexity of the geometric shape of the structure leads to an increased consumption of material, does not become an obstacle for those who seek to complete their building with an interesting and original accent.

A multi-gable roof, the drawing of which for many may seem no less complicated, nevertheless, can be erected independently, but subject to strict adherence to the requirements of construction technology
How to make a multi-gable roof: device tips

Multi-gable can combine under a single roof structure a number of roofs that differ in their type and purpose. The complexity of its device lies in the large number of ribs, valleys, grooves. Its spire is rather artistic in nature, and it is often used to install towers and domed roofs, emphasizing architectural style. One of the most popular today are two-level coatings and half-hip roofs.
Rafter device

The basis of the roof structure is the truss system. Most often, it combines diagonal and hanging rafters directed to the corners of the walls. The complexity of such structures lies in the fact that all slopes do not rely on Mauerlats, as usual, but on diagonal legs. That is, the bearing capacity of the structure depends not only on the calculation of the sections of the system elements, but also on the implementation of the connection nodes and the installation of stiffeners.

The main node is considered to be the joint at one point of the ridges of the same level of different sections of the roof. The ridge bars are connected at a right angle, but, in addition, each of these angles also includes oblique legs, which are the main support for almost all rafters. The strength of this node is increased by installing puffs.
Slanted rafters are longer than conventional ones, so they are made paired. This technology simultaneously solves several problems:
a rafter with a double section is able to withstand an increased load;
rallying the boards makes it possible to obtain a continuous beam of greater length;
when connecting, the standard size of the parts used is unified.

It turns out that it is practically possible to use the same boards for diagonal devices as for ordinary ones - and the use of boards of equal height for any type of rafters simplifies the constructive solution of roof nodes. In addition, semi-legs or joists are supported on them, thanks to which the layered supports are able to carry a load that is about one and a half times more than the maximum load for ordinary rafters.

The leaning of the sprigs on the diagonal leg is performed in two ways:
top surface support. A cut is made in the rafters in such a way that half of their section - the upper one - is above the diagonal leg, and the lower one rests on side surface.
Support on the side. The main thing in this case is how well the supporting parts fit. The lower rafter can be more firmly connected to the diagonal leg beam by nailing an additional support boss from the trim.

The bottom of the sloping supports is usually for landing on a truss, a beam of timber, thrown along intersecting outer walls at a corner, a surf or a run console is cut into the horizon and fastened with nails.

But the diagonal supports located in the valley cannot be supported with a trussed truss.

A truss truss is a truss structure with two struts installed.

The fact is that the valley forms the inner corner of the walls, so they must be supported with racks or, in last resort struts.

By the way, installation roofing in the case of a multi-gable roof, they start with the installation of valleys, which are formed at the intersection of mutually perpendicular planes. At the same time, the technology for the execution of this node depends entirely on the material used as the main one for the roof.

A multi-gable roof over a square house has a large number of valleys, ribs, gables, gables. The gable is the upper part of the wall of the building, which is limited by two roof slopes and is not separated by a cornice from below.

When the upper part of the wall is separated from the lower part by a cornice, then this is already a pediment. The gable roof consists of two planes that rest on the walls and are limited by gables or gables from the ends.
What is a multi-gable roof

Multi-gable roofs are arranged on houses that have a complex layout, with side lighting of attics, covering extensions, gables above the entrances.

When constructing a roof such as a four-pitched hip roof, elements such as valleys must be present. You also need to know that a building with such a roof must have a ventilated attic, which will be completely isolated from all warm rooms.

Multi-gable roofs require a large consumption of roofing materials, and after its installation, quite a lot of material waste remains.

Such a type as a do-it-yourself ordinary half-hip roof is formed by installing several slopes. This is a rather complicated construction, the main disadvantage of which is the complexity of implementation.

When constructing this roof, the intersections of the slopes form internal corners (valleys). A large amount of water flows down them and therefore close attention should be paid to the waterproofing of such corners.

In addition, a large amount of snow can accumulate in the valleys, and this significantly increases the load on the roof. The main advantage of a multi-gable roof is its expressive appearance, as well as the overlapping of several rooms with a single-level roof.
gable roof

A gable roof is the heaviest roof in the construction of roofs, since there are many valleys, grooves, and ribs in the design. It is mainly used in buildings with polygonal building design, difficult architecture.

Gabled hip roofs are often used in the construction of private houses. The spire has an artistic character, and such elements are installed on domed roofs and towers.

These roofs do not carry a useful meaning, but they do a significant job in creating the architectural style of the building. IN individual construction gable roof is a complex of several forms, sometimes so intricate that it is even difficult to recognize them.

Today, two-level coatings and half-hip roofs are popular.

Your attention!

The most simple design represents the intersection between each other at an angle of 90º of two pitched roofs.

The rafter system of a multi-gable roof consists of rafters, mauerlat, girders (beams). An element such as a mauerlat redistributes the load from the roof to the walls of the house through the rafter legs and thus connects to the walls.

It consists of wooden bars 150x100 mm and 150x150 mm. And also for this use pieces of timber having a length of 1.5 meters. The rafters for such a roof are assembled from dry pine boards, which have a section of 150x50 mm.

Rafters are hanging and layered - it depends on the presence or absence of additional supports, as well as on the design of the multi-gable roof. In the roof device, both types of rafters can be used simultaneously.

In places where gable roofs are articulated, slanted or diagonal rafter legs are installed, on which the sprigs (shorten rafter legs) will rest. Due to the fact that a very large load acts on the diagonal rafters, they need to be strengthened - to be rallied into two boards.

In the upper part of the rafters, they are connected with a ridge run made of boards or timber cohesive among themselves. If necessary, additional intermediate runs are installed.

After the rafter system is installed, the waterproofing film is laid in strips, perpendicular to the direction of the slope, with an overlap of at least 15 cm, as well as with mandatory gluing of the joints using connecting tapes.

Close attention should be paid to the places where the valleys are located, as large flows of water will flow along them.

On the rafters, bars of the counter-lattice are sewn after laying the waterproofing layer. Basically, bars with a section of 50x50 mm or boards of 32x100 mm are used to perform such work. Sheathing should be carried out in accordance with the instructions for the selected roofing.
Gable roof construction

gable roofs

A lot of owners of private houses want to know how to make a multi-gable roof.

This type of roofs are rather complex structures, and when such a structure is constructed, several fragments of the building can represent gable variations, which are then combined into a single complex, while creating an amazing impression.

Do-it-yourself construction of a four-gable roof consists of the following steps:

It is necessary to take the correct dimensions of the house;

Correctly position stops, skates, valleys;

· then you should install a Mauerlat, which should run along the perimeter of the wall and serve as a reliable "foundation" of the roof;

Then the crate, waterproofing, the roofing itself, as well as steam and heat insulation are installed.

The design of the multi-gable roof is a pitched roof with sloping roof surfaces towards the outer walls and at the same time provides a natural runoff of melt and rainwater.

The choice of slope directly depends on the climatic conditions of the region, the roofing material and architectural requirements. In some areas, the slope angle is 90º.
The main elements of the roof

Schematic of a four-gable roof

The structural scheme of the four-gable roof consists of the following elements:

1. inclined planes - slopes;

2. rafters;

3. crates;

4. Mauerlat;

5. horizontal and inclined ribs;

6. skate;

8. grooves;

9. overhangs;

10. gutters.

The device of a multi-gable roof is a rather laborious process, since additional diagonal rafters should be installed at the intersection of the slopes when erecting such a structure.
In this case, elements such as grooves are formed, which are also called "snow bags". And when installing the roof, special attention should be paid to these elements, since with poor-quality installation, the roof will definitely leak in these places.
Roof shapes

At intricate roof it is necessary to install valleys, which are the least reliable place on the roof, since snow accumulates in these places and the load on the truss system increases.

The four-gable roof is a design of slopes on four sides. It is also called hip or tent, and slopes - hips.

These structures do not require gable walls, but the truss system is more complex than the gable one.

Roofs are, as you know, flat and pitched. Pitched - architecturally more expressive and, in addition to the protective function, they also have a decorative function. The number, shape and size of the slopes depend entirely on the personal preferences of the owner and the designer's intent, taking into account, of course, climatic conditions and operating requirements.

Design features: pros and cons

Multi-gable roof - the design is quite complicated. It is distinguished by the presence of numerous intersections of slopes, at which valleys are formed, the so-called formed internal corners.

Rafter device

The main node is considered to be the joint at one point of the ridges of the same level of different sections of the roof.

At the same time, the technology for the execution of this node depends entirely on the material used as the main one for the roof.

Multi-gable roof and its features

Multi-gable roof- this is the view pitched roof, the design of which consists of several or many tongs (gable elements with skates), along the edges of the overhangs forming gables in the structure.

Multi-gable roofs are a complex structure, the distinguishing feature of which is the presence of gable elements intersecting or cutting into the main slope, forming numerical valleys on the roof.

Design features

A multi-gable roof is considered a complex structure. The complexity of the design is explained by the presence in such roofs of a large number of valleys and gables, the installation of which causes specific difficulties and additional costs.

The arrangement of the valley requires especially close attention, because it is through them that streams of rain and melt water will flow in the future. Also in these places there is the greatest accumulation of snow, and therefore they must have a significant bearing capacity and tightness. The professional formation of the valley, the main vulnerable element of the roofing, ensures reliable drainage of melt and rainwater from the roof.

General concepts

The truss system of a multi-gable roof is a rather complex structure. To perform its calculation and installation, you need to have some experience. But before talking about it, you should get acquainted with the very concept of a multi-tweezer design. What is this roof option? Why is she called that?

This design is a multi-pitched roof. Its most important difference is the presence of tongs or gable elements with a ridge. It is from them that the whole structure took its name. Each of the tongs rests on one side of the truss system of the main roof. The other end forms a pediment.

The device of the truss system of a multi-gable roof has its advantages, namely:

This design has high bearing capacity and strength.
The truss system of a multi-gable roof is calculated based on increased loads. This feature allows the structure to easily withstand even hurricane winds and large layers of snow.
The slopes of such roofs are made quite steep. This prevents debris from accumulating on them. This means that maintenance of the roof is greatly facilitated. In addition, such a roof, if properly erected, does not require repair for a long time.
Thanks to the highly located ridge, a lot of free space is formed under the multi-gable roof. This allows you to freely create additional living rooms on the attic floor.
Another advantage is that such a design can be used even if the house has a complex geometry.

But do not forget about the difficulties. The rafter system of a multi-gable roof is a complex structure. If you do not have sufficient experience in construction and carpentry work, then it is better to entrust its construction to specialists.

Basic structural elements

As mentioned earlier, the truss system of a multi-gable roof is several gable structures connected together. Therefore, the basic principles will also be similar. In our case, both hanging and layered rafter systems can be used. As a rule, the main structure has a large width. Therefore, a layered truss system is used here. Attachments use hanging structures, everything will depend on the width of the building and the presence of an axial load-bearing wall.

In addition, the multi-gable roof truss system incorporates the following main elements:

slopes. Their number in a multi-gable roof can differ significantly from the traditional design. At the same time, the sizes, shape and steepness of unpaired slopes can also vary;
skate. There will also be several of these elements;
ribs - these elements are located at the junction of the slopes. Moreover, they can only be in those multi-gable roofs where hips are used;
valley. Not one multi-gable roof can do without this element. This element is located at the inner corners where two slopes converge. Endova needs to be addressed Special attention. This is where snow can accumulate in winter. Therefore, in such places a large load is experienced and leaks most often occur, it is useful to read: a valley on a metal tile.

Of course, other elements may be present. For example, pediments. They close the ends of the tongs themselves. At the same time, the pediments can also finish the main roof, if it is not cable-stayed, it is useful to read: the pediment is made of corrugated board.

Making calculations

The rafter system of a multi-gable roof is a complex structure. Therefore, it is impossible to do without preliminary drawing up its scheme. But first of all, you should make all the basic calculations. Before drawing up a plan for the future rafter system of a multi-gable roof, the following basic parameters should be clarified:

Skate height. To do this, use indicators such as the width of the house or extension (depending on which building is being calculated) and the angle of inclination of the slope. Very often, reverse calculations are carried out. Initially, the desired height of the house is determined, and then the slope angle of the slope is calculated. It should be noted that the width of the main house and the extension will be different. And this means that the angle of inclination of the rafter system of a multi-gable roof for each building will be different. This is the difficulty of such a device.
Next, you should find out the length of the main rafters. This parameter is easy to calculate from the Pythagorean formula. In this case, the length of the rafters for the main building and the extension will be different.
You should also calculate the length of the valley. This is where the rafters will be located. The Pythagorean theorem will also be used here. The valley will be the hypotenuse. The triangle itself consists of the length of the rafters of the main building and half the width of the extension.
Between the ridge and the rafters are sprigs. Their length should also be found using the Pythagorean theorem. The rafters will be shortened rafters.

The total area of the roof is also calculated. It will be the sum of the areas of all the slopes of the multi-gable roof. This value is necessary to calculate how much roofing material you need during installation, read additional material: calculation of the truss system.

Load

The rafters of a multi-gable roof, like the entire system, must withstand all external influences. Therefore, even before the calculation of all the main parameters, the load should be calculated. Experts distinguish between two types of it, namely:

permanent. This group includes the load on the truss system of multi-gable and other types of roofs, caused by the weight of the materials used. It also includes the mass of all equipment installed on the roof;
variable load. This group includes the effects of external factors. The rafter system is affected by the weight of the snow cover, which will linger on the roof. In addition, the wind also has an effect.

Knowing what angle of inclination of the slopes will be on your roof, you can calculate the variable loads. By adding to them the mass of all the materials used in the construction of the roof, you can determine the total impact that the entire structure must withstand, it is recommended to read: calculation of the gable roof truss system.

Knowing all the loads, you can determine the cross section of the rafters. The greater the load, the thicker the main elements of the system should be. In addition, after such calculations, the distance between the rafters or step is also determined. Also, if necessary (for example, if the rafter legs are too long), specify the location of additional supporting elements. After all this, a drawing is drawn up.

To perform all these calculations correctly, especially to draw up a diagram of the future truss system of a multi-gable roof, is a difficult task. It is better to entrust it to specialists. Or you can use special programs. With their help, by specifying all the necessary data, you can not only calculate all the parameters, but also draw up a plan for the location of all components of the multi-gable roof truss system.

Installation of the truss system of a multi-gable roof is not much different from the traditional one. gable system. All work is carried out in the following sequence:

The first step is the installation of the Mauerlat. In the case of a multi-gable roof, this work must be done not only on all external load-bearing walls, but also on internal ones. The latter would be more correct to be called lying down.
Next, you should install the ridge run. Most often, a multi-gable roof over the main building is installed in a layered way. Therefore, you cannot do without a ridge run. Above the extension, a hanging truss system is most often used. In this case, the ridge run is not used. https:="">

Particular attention should be paid to the section of the multi-gable roof, where the valley will be located. The rafter system itself in this place must be reinforced with props. In addition, it is necessary to make a thorough waterproofing and lay the roofing material with high quality. All this is necessary because it is this area that is subjected to the greatest loads, especially in winter.

Among various designs roofing is considered the most complex and attractive multi-gable. The peculiarity of its design lies in the large number of complex elements. These include gables, tongs, valleys and ribs. In this article, we will tell you how to build a multi-gable roof with your hands, show drawings and diagrams, photo and video materials.

Most often, a multi-gable roof is made in several cases:
- initially;
- in the process of building extensions;
- for mounting side lighting in the attic;
- in buildings with a complex layout and many rooms.
Peculiarities

Scheme of the truss system

A simple gable roof option is a gable roof without gables. In this design, the upper triangular section of the wall is called a gable. In the process of building a multi-gable roof, there is no simple steps, all actions, starting with calculations, require knowledge and skills. The device of the roof allows you to place a living space under it. Despite the difficulties, homeowners take on self-assembly which saves a significant amount of money. A multi-gable roof will require enormous physical and financial costs, but will delight the creators with the architectural beauty of the building.
- thanks to a balanced rafter system, the roof can easily withstand high loads;
- the roof has an original and attractive appearance;
- the design is reliable and durable;
- there is free space for extra room or attic;
- snow cover does not linger on steep slopes.
- complex design that requires competent calculations and installation;
- a large amount of waste generated when cutting roofing material, especially metal tiles;
- high load on the valley due to snow;
- the need for high-quality waterproofing of internal joints.
Designations of the main structural elements

Roof device

Endova - place inner connection rays, they are one of the key nodes. They have to withstand a significant load from the accumulation of snow, so support from the system of props and struts is performed from below. The waterproofing of the node is of great importance, all the water flowing down the roof passes through the valleys. Any design error will result in a leak.

Ribs- represent outer corner connected slopes. One of the most difficult places in the construction of a multi-gable roof is the intersection of the ridge beam, to which the valley adjoins. The ridge is one of the ribs of the roof.

forceps- a section of the wall bounded by slopes, it turns out in the form of a triangle and is not separated from the wall by a cornice.

Mauerlat- the bearing base of the entire roof, distributing the load on the walls and foundation.

rafters- layered, hanging and diagonal.

crate- a frame made of timber, necessary for fixing roofing material and insulation.

Installation of the truss frame

Roof truss system

The basis of the multi-gable roof is the Mauerlat. The base element is subjected to a high load, so a bar with a section of 150 × 150 mm is used for it. It is attached to the walls of the building with anchors laid in the process of building the house. The rafters rest on the Mauerlat. Rafters can be layered and hanging. Their choice is determined by design features.

In the case of a hip and semi-hip roof, diagonal rafter legs are installed at the junction of the slopes. These elements account for the main load, so they require reinforcement by sparrows. Such rafters can be made double, connected from two boards 150 × 50 mm. Rafter legs, reinforced with struts and crossbars, form trusses. To ensure an attractive appearance of a multi-gable roof and the necessary rigidity of the structure, all parts of the trusses are made in a template. Novice builders can assemble trusses not with the help of a cut, but by fastening them with overhead metal elements.

After installing the rafters, a crate is stuffed on them, at the junctions of the slopes, where the valleys are arranged, it is solid. The inner corner waterproofing scheme provides for the laying of an additional layer to ensure the reliability of the structure. Waterproofing is laid on the boards and the bottom bar is mounted. If the valley consists of several parts, they are attached from below, the edge of the lower element overlaps with the upper part. The junction of the lower bar and the roofing is insulated. To give the structure a finished look, it is installed top bar valleys.

Sheathing, insulation and roof installation

The last element of the truss system is the crate. It is stuffed onto the rafters with a step depending on the choice of roofing. For soft roof it is continuous, for metal tiles - in increments of 25–30 cm. A sheet for waterproofing is laid horizontally on the crate, the overlap of the strips is 10 cm. If insulation is provided, then the material is laid under the waterproofing. When insulating a structure, one should not forget about ventilation holes. For a multi-gable roof, a light weight coating is recommended so as not to create additional stress on the rafters, for example, when laying metal tiles.

Installation of the roof of the multi-gable roof is completed

There are many options for how to make a multi-gable roof, they differ in design complexity and appearance. This type of roof looks most organic on square and rectangular houses.

The main nodes of the structure

Private houses are decorated with roofs of various shapes. Among them there are tongs. They are a structure that rests on two walls of the same height. Such roofs have two slopes. The end part in its shape resembles a triangle. If the walls are made of wood, then such a triangle is called tongs, and if made of brick - pediments. You can make a gable roof with your own hands.

Gable roofs have two slopes. There are no restrictions on the choice of roofing materials.

When constructing such a roof, as a rule, material waste is minimal. This is due to the fact that the shape of the slopes is rectangular. By the way, slopes can have different lengths and angles of inclination.

Such a roof is characterized by the use of a warm attic, which is used as an additional room. can lead to additional costs for materials and complicate the work.

The optimal angle for the slope is determined within 20-45 degrees and depends on the construction area. If the terrain is snowy, it is better to increase the slope to avoid the formation of snow accumulations.

The device of such a roof begins with laying out the end parts - tongs. This is not the easiest task, because they must be exactly the same.

To calculate the length of the slope, use the Pythagorean theorem, familiar to everyone from school. So, if we imagine that the slope is the hypotenuse of the calculated triangle, then one of the legs will be the height from the beginning of the slope to the ridge along the plane of the wall, and the second - half the length facade wall.

If the house has simple form in plan, then you can use the use of a gable roof, but if the shape of the structure is complex, then an option appears using a multi-gable roof. It is more difficult to build them, because they have a lot of valleys.

Gable roof device

When constructing such a roof, two types of rafters are used - layered and hanging..

Slanted are a structure that has a support beam in the middle, which transfers the load from the ridge to the Mauerlat, laid on load-bearing walls. This beam is mounted in the middle of the outer walls.

Hanging rafters are used in cases where the distance between the walls is less than 10 meters or there is no load-bearing wall in the middle of the house.

They are supported on the side walls. However, this creates a rippling effect. It gives additional load to the walls. To avoid this, the design of the hanging rafters provides for connecting the rafters with puffs in such a way that a triangle appears. Floor beams can be used to perform this function.

Puffs can be mounted from above and below. In this case, the upper ones must be installed in such a way that the distance from the ridge is more than 50 centimeters.

materials

For work you will need:

Mauerlat. Suitable for him wooden blocks section 15x10 or 15x15 centimeters;
rafters. For them choose pine boards with a section of 15x5 centimeters.
spacers;
counterlattice. It is laid after a layer of waterproofing. For her, choose bars with a section of 5x5 centimeters or boards 3x10 centimeters;
the lathing is selected under the roofing. It can be made of edged or unedged boards, plywood, OSB boards.

Stages of work

Depending on the design of the house, we choose the right one.
If the rafter system is hanging, then the rafter legs are assembled in advance. And after the assembly is completed, the resulting rafter triangles are mounted on the two extreme structures of the truss system. Next, proceed to the installation of adjacent rafters.
We lay the mauerlat (support beam) on the load-bearing walls, provided that the house is made of blocks or bricks, but if the building is built of beams or logs, then you can use the top bar as a mauerlat.
Mauerlat is attached to brick walls on pre-walled threaded metal rods. They should be installed in steps of a meter and a half. This will make the structure more durable and stable. In this case, the diameter of such rods must be at least 10 mm.
Before installing the Mauerlat on brick walls lay a layer of waterproofing (roofing material can be used for these purposes). It is attached to bolts with washers.
If the walls are made of foam concrete or ceramics, then before installing the Mauerlat, their surface is poured with reinforced concrete 20-30 centimeters high.
Mauerlats are installed parallel to each other to avoid irregularities during the installation of the truss system.
Before installing the rafters, it is necessary to make markings on the Mauerlat using a pencil and a ruler.
Rafters are made in accordance with the length of the slope, which can be determined by the Pythagorean theorem, based on already built tongs.
When calculating the length of the rafters, it is necessary to take into account the presence of an overhang, therefore, another 50 centimeters are added to the calculated value.

The length of the overhang depends on personal preferences for the appearance of the roof, but it is not recommended to make it less than 50 centimeters, otherwise it will not perform its functions - protecting the walls of the house.

The lower end of the rafter should have a hole that will create a perfect attachment to the Mauerlat. This cut should be made 1/3 of the width of the rafter.

In order not to be mistaken with the location of the cutouts, you can prepare a small drawing, where you mark all the necessary values.

With a hanging system of rafters, they are attached to each other on metal plates or bolts.
They are fixed with jibs, dismantled after completion of work.
Next, the filly is fastened, which will form the overhang of the roof.
After the filly and rafters are installed, they proceed to the installation of the crate and massive durable boards to the horse.
If we are talking about layered rafters, then the assembly begins with the installation of the bed. Supports are attached to it.
This is followed by the installation of a ridge beam, fixed with jibs.
And in the end, rafters with a length exceeding the length of the beam are mounted on the beam.
The type of lathing is chosen depending on the roofing.
Any roof, including a gable one, should be provided with a layer of hydro and vapor barrier. And in the presence of a warm attic, there is also a heater.

The multi-gable roof is also gable, and differs from the gable roof in a large number of slopes and the presence of valleys. Their device is a rather complicated and time-consuming process. Valley - these are the junctions of two slopes, when an internal corner is formed. In such places, accumulations of snow form and a large load can lead to the destruction of the structure. When organizing such a roof, it is imperative to provide for the organization of the descent of water and snow in the form of gutters.

When arranging valleys, it is mandatory to use waterproofing materials to avoid leaks and the formation of rot on the wood. The lathing in the place of such internal corners is made solid, regardless of what it is for the selected roofing. All joints should be done with high quality, without the possible formation of cracks, so that there are no vulnerabilities.

To install such a roof, it is necessary to correctly calculate all the dimensions of the house and draw a small roof plan, on which you indicate where the skates will be located, and where the valleys will be located. This will help to correctly calculate the length of the rafter legs.

Before deciding to build such a roof, think carefully - are you ready to fork out in the name of beauty? This roof does not carry any particular benefit, but it also has no serious drawbacks.

For those who are planning to build a house and want to turn it into a real work of art, a multi-gable roof will allow you to realize the most original fantasies in this matter. Multi-gable roofs of houses quickly won the hearts of those who love something exquisite and have enough finances, because this type of roof is not cheap.

Multi-gable roof - advantages and disadvantages

You can often hear that this type of roof is used exclusively in the construction of square houses, but this is a myth. It happens that all kinds of premises are completed to the house, and it takes on an awkward shape. In this case, a multi-gable roof completely transforms the appearance of the house - it looks very impressive!

As for reliability, the multi-gable roof device is very strong, but only if the installation of the truss system is done correctly. If you are not a specialist, then it is better to contact experienced builders.

There is a lot of space under a multi-gable roof, you can make a spacious attic or equip a luxurious attic, often for the sake of it such a roof is built to provide good lighting.

Important: when building a multi-gable roof, it is impossible to equip the entire room as residential - you need to select a part in which there will be a ventilated room, separate from the heated one.

Among the shortcomings can be identified:

High cost. Uneconomical consumption of wood, you need to constantly cut, trim, and as a result, some of the material is simply thrown away. The truss system of a multi-gable roof is difficult to install, respectively, the craftsmen charge a substantial amount for work.

High risk of leaks. A feature of such a roof is a lot of slopes, and the places where they intersect are called endova - the most vulnerable places of the roof. There are large flows of water, and if you do not pay attention to the quality insulation of these joints, then at the first opportunity they will leak.

Multi-gable roof elements

The rafter system of a multi-gable roof is the same as that of other roofs - Mauerlat, rafter legs, ridge, water drainage grooves, lathing and more inclined ribs with additional racks. All this is fastened together with metal fasteners.

The difference from the standard roof is the presence of ends, grooves, many ribs and slopes.

It was said above about the endovs - these are depressions that form at the junction of the slopes, they are also grooves. The ribs are also the joints of two slopes, only they do not go inward, but outward. It is in these elements that all the “sweetness” is, because they form the tongs and the numerous hips (slopes), giving the roof such a special look.

Types of multi-gable roofs

In architectural terms, the hip roof can be given the most elaborate look. There is a place to show imagination and surprise with the unusual form.

Multi-gable roofs are the most popular type. Despite the fact that such a design requires careful fastening with the correct distribution of the load. Pointed corners give the structure rigor and concise completeness. Any Vacation home with such a roof looks rich and original.

Semi-hip gable roofing is also a fairly common type. Installation is a little easier. A characteristic feature of this species is the "smooth" corners. The roof looks flowing and elegant, somewhat reminiscent of a tent. It is only at first glance that it seems more modest than the previous view, if you approach its construction creatively, it can turn out to be unusually beautiful.

truss system

Simply put, the rafter system of a multi-gable roof is two gable roofs that are connected to each other at an angle of 90 degrees.

Due to the large weight and complexity of the structure, both types of truss systems are used in the construction of such a roof - hanging and layered, and also create

multi-gable roof scheme

A few words about how a multi-gable roof is built with your own hands:

On the Mauerlat, with a section of 150x150 mm and a length of 1.5 m, rafters of 150x50 mm are attached.

The rafters are fastened at the top with a ridge of the desired section, then the structure is reinforced by installing intermediate runs.

Since in this design there are places where two roofs are connected, additional rafters must be made there in order to attach sprigs to them.

multi-gable roof - drawing

When all the racks and fasteners are in place, you need to lay a layer of waterproofing film.

The crate is made of boards measuring 32x100 mm. You can bars 50x50.

Important: before installing the rafter system, you need to correctly calculate the slope of the slopes and the load on the rafters so that the structure is strong. It is desirable that this be done by a specialist. In addition, the climatic location is important - if a lot of precipitation is expected, then the slope of the hips should be maximum so that water and snow do not linger. You need to take care of the endows - clean off snow and debris from them.

Be that as it may, experts do not recommend starting the construction of a multi-gable roof on their own. If only because the material will cost you a lot of money and it will be a shame if nothing works out. Of course, the masters will also take a lot, but in the end you will be pleased with the beauty and reliability of an architectural masterpiece.

A multi-gable roof is a rather complex structure for erection. She has many different structural elements: a lot of rays, ribs, forceps, valleys.

Multi-gable roof

The erection and covering of such roofs require a great deal of experience in construction works Oh, correct calculation the entire roof structure, as well as taking into account all the expected loads that will subsequently affect the supports.

What is this type of roof and its design features? You can learn about this and other details of the construction of a multi-gable roof from this article.

The main advantages of a multi-gable roof:

Attractive appearance. These roofs came to us from the west, where they were most widely used for their attractive appearance;
The practicality of this type of roof. Snow or other precipitation hardly lingers on the roof slopes at all, but quickly disappears due to the grooves and the large slope of the roof slopes;
Strength and durability of the entire structure. Such a roof can withstand heavy loads, thanks to a balanced rafter system. This, of course, is one of its main advantages;
Efficient use of space under the roof, which makes it possible to equip additional premises;

But there are some disadvantages that also need to be mentioned:

The complexity of the whole structure. If a multi-gable roof is being built with his own hands, it means that the owner of the house himself has rich experience in such work or an excellent consultant, otherwise, you can easily make mistakes and then it will hardly be possible to do it right;
Large waste of materials. Since the roof has multiple bends and slopes, a large amount of waste will be generated during the process of covering it with roofing material. From which we can conclude that the construction of a multi-gable roof is not a cheap pleasure.

Based on the above pros and cons, you can make a decision, but is, in fact, the “game of candles” worth it?

What is a multi-gable roof made of?

So, what are the main elements it consists of? Let's take a closer look:

mauerlat is a special bar that is placed around the entire perimeter of the building, then the entire truss system is supported and attached to it;
grooves through which precipitation is discharged;
inclined planes of slopes;
horizontal and inclined ribs;
rafters - special wooden poles and boards;
crate to evenly distribute the load from the weight of the roof;
overhangs are the edges of the roof, which are located above the walls of the house;
drains where precipitation flows;
ridge - the upper part of the roof;
valleys - the angles of the connection of two slopes.

The difficult arrangement of the roof is due to the fact that in those places where there is an intersection of slopes, it is also necessary to install diagonal rafters so that the whole structure is complete and complete.

When installing a multi-gable roof, it is imperative to pay attention to such an element as grooves. If they are installed and installed incorrectly, the roof may subsequently leak.

Variety of multi-gable roof shapes

If a decision is made to create a multi-gable roof, then valleys cannot be dispensed with. In this case, one way or another, the junctions of the two slopes will appear, and you need to pay special attention to the junctions. Since these are the internal corners of the roof, the load on them will be much higher than on the rest of the roof. Therefore, the correct construction of the docking of the slopes is the reliability and durability of the roof being built.

In another way, a multi-gable roof over a square house is also called a hip roof, since this version of the roof has four slopes located on opposite sides of the house. The stingrays themselves are called nothing more than hips.

Such a roof involves the construction of additional gable walls, and the entire truss system in this case becomes more complicated. In rare cases, you can find a half-hinged four-gabled roof, where two slopes running along the sides are slightly cut off from a large gable.

This explains the difference between the half-hips and the main slopes, they usually have a much shorter length, in the part where the slope line goes. Such half-hips can be built in the upper part of the roof, in the form of a triangle, and in this case the gable will be in the form of a trapezoid. In this case, this tong will protrude forward from the wall.

Design features of multi-gable roofs

It is believed that the installation of a multi-gable roof should be carried out on those houses that, in their design features, have a very non-trivial layout. It is also used in cases where it is necessary to increase the attic space, creating more space in it for additional living space.

A multi-gable roof over a square house is the most common option and much less often the base of the roof looks like a polygon, as this requires additional calculations. If the roof structure assumes the use of slopes in the form of equilateral triangles, then their vertices must converge at the same point.

Today there are finished projects various forms of multi-gable roofs. If we talk, for example, about a four-slope hip roof, then in this design there must be valleys. Necessary condition in this case, there will be a ventilated (ventilated) attic room, it must be completely isolated from other rooms kept warm.

Another point to consider is that such roofs consume more building materials, i.e. after installation, quite a lot of waste remains.

If we consider, for example, the construction of a semi-hip roof, then its main feature is the installation of several rafters. Such a design will be quite complicated in execution, and this must be remembered.

In the manufacture of such a design, the number of slopes obtained also gives a certain number of internal corners, the so-called valleys. This necessary element roofs, because it is along the valleys that unnecessary precipitation rolls down. Therefore, special attention should be paid to this particular element, which is necessary for isolation from water.

Valleys are also characterized by the fact that in these places the probability of snow accumulation in winter is the greatest, which can lead to additional load on the roof. Therefore, in winter, the roof (multi-gable) must be periodically cleaned, freeing it from excess precipitation.

Architectural complexities of a multi-gable roof

Needless to say, the construction of a multi-gable roof is a difficult task even for experienced professionals. Indeed, in the design of this type of roof there are valleys, and grooves, as well as many ribs, while all this must be correctly connected, which requires great skill and experience in construction work.

Therefore, it is not surprising that it is mainly used to create projects that are architecturally complex, where polygonal structures and elements are planned.

The greatest use of gable roofs can be found in private construction, which is explained by its beauty and aesthetic qualities and characteristics. In the private construction of houses, one can often find such intricate and complex forms of roofs that it is sometimes difficult to even recognize that this is a multi-gable roof.

The most popular representatives of multi-gable roofs can safely be called half-hipped roofs.

The simplest of the multi-gable roofs is the one in which two roof slopes intersect at a ninety-degree angle.

Multi-gable roof, features of the truss system

First of all, it is necessary to clarify what the rafter system of such a roof consists of. This includes the rafters themselves, special runs (beams), and, of course, Mauerlat is its indispensable attribute. Mauerlat is one of the important components of the entire system. It serves to redistribute all the loads of the roof on the walls of the whole house.

Usually, these are wooden blocks of a certain size, in this case 150 x 100 millimeters. As for the length, it can be different, but basically it has one and a half meters. The rafter system is best made from pine.

Rafters, in turn, are divided into two types - hanging and layered. Which will be used in construction depends on the specific design features gable roof. Sometimes both types of rafters are used in hotel structures.

Where the gable roofs are connected, diagonal rafters (legs) should be present, and the rafters (which will hold the support) should already be installed on them.

Since the diagonal rafters take on a very large load in such roofs, they almost always need to be reinforced by connecting them into two boards.

In the upper part of the roof, the rafters must be connected by a run, which is made from bars or boards connected to each other. If such a need arises, then additional intermediate runs are sometimes mounted.

After the installation of the truss system is completed, you must not forget to lay the waterproofing film. It should run in a perpendicular direction with respect to the slope, while you need to make a small overlap, about 15 centimeters. At the joints of the joints, for greater waterproofing, it is necessary to walk with a connecting tape. Be sure to pay attention to the roof valleys, they also need to be reliably waterproofed, since it is in these places that precipitation will come off the roof.

When the rafter system is ready, after installing the waterproofing layer, it is already possible to lay the counter-lattice. The most common material for crates are bars. If to roofing material there is an installation instruction, then it is better to do it according to this instruction.

Stages of construction of a multi-gable roof

So how, after all, to make this difficult multi-gable roof? As mentioned earlier, a multi-gable roof structure is nothing more than joining several gable roofs together. When they are connected, the house looks much better and makes a very favorable impression from the outside.

Do-it-yourself multi-gable roof is built in several stages:

carrying out very accurate calculations that contain the dimensions of all elements of the house and the roof, the calculation of snow and precipitation loads on the roof of the building;
correct calculation of the length and required section of the rafters;
put a mauerlat along the entire length of the bearing walls, which will then be the basis for the entire roof;
installation in the right places of the main details of the roof structure (various stops, grooves, skates and others);
installation of the truss system on the Mauerlat, using nails or reinforcing pins (if the main frame of the house is made of concrete structures);
last step works will be the installation of lathing, as well as layers of vapor and waterproofing before covering the roof.

So, after finding out the features of the construction of a multi-gable roof, important conclusions can be drawn: most often a multi-gable roof is erected over a square house, depending on the climate of the region, the angle of the slope of the slopes is chosen, the increase in costs and the complexity of the design is compensated by obtaining additional space under the beautiful roof of your house.
