reference

A wooden staircase with turning steps allows you to significantly save space in the house without losing convenience and functionality.

When calculating, pay attention to the optimal number of rotary steps. In my experience, 3 steps are optimal with a staircase width of 80 cm. More - the steps will be too narrow and therefore uncomfortable.

If the opening is located only above the top of the stairs, then the height at the turning point before the overlap is important in order to avoid head injuries. It must be at least 2 meters.

With this design, the width of the stairs plays important role. Since it directly affects the convenience of turning steps. The wider the staircase - the more steps can be used without loss of convenience.

Due to the variety of projects and designs, the railing for stairs in the program is not calculated in any way and is not shown.

Important! Pay attention to the dimensions of the turning steps. To get the dimensions of the step - do not forget to add the size of the protrusion to these dimensions.

The calculation of a stone staircase for is no different from the calculation of a wooden or metal staircase. The main thing is to correctly calculate the dimensions of the steps. Their height must be the same for all its parts.

The calculation of the convenience of the stairs is calculated by a formula based on the length of the step.
Human stride length ranges from 60 to 66 cm, with an average of 63 cm.
A comfortable staircase corresponds to the formula: 2 step heights + step depth = 63 ± 3 cm.

The most comfortable slope of the stairs is from 30° to 40°.
The depth of the steps of the stairs should correspond to shoe size 45 - at least 28-30 cm.
The lack of depth can be compensated by the protrusion of the step.
The height of the step should be up to 20-25 cm.

The program will draw drawings of stairs with turning steps with basic angles and dimensions.
The drawings show the overall dimensions of the stairs, marking the top of the steps on the bowstrings, the corners of the steps and the main dimensions of the steps themselves.

I hope the program will help you design and make a staircase for your summer cottage or home with your own hands.

Rice. 1 General drawing stairs

"Show risers: H" function

Fig.3 Execution of stairs with risers

You can build your stairs with or without risers. The drawing of the stairs allows you to see how the structure will look like with both options.

"Upper step below floor 2nd floor: SP" function

Rice. 4 Stair version, with the top step below the floor 2 floors

Depending on the mutual placement of the structure and the floor of the upper floor:

1. The top plane of the top step is flush with the plane of the floor of the top floor;
2. The upper plane of the upper step is lower than the floor plane of the upper floor by the height of the step.

The choice of this or that mutual placement may depend on: the thickness of the interfloor ceilings, the desired relationship between the number of steps and their height, the length of the blanks for the stringers and the length of the opening, the desired angle of inclination of the stairs, or simply the tastes and preferences of the owner of the house. Please note: in the figure, in which the upper step is below the floor of 2 floors, the thickness interfloor overlap more than in the figure, in which, the upper step is at the floor level of the 2nd floor. If the thickness of the floor is less than the height of the step, the stringer simply does not rest against the floor (therefore, when demonstrating the second option, this thickness had to be increased).

"Black and white drawing:" function

Rice. 5 Black and white drawing of stairs

It is useful to use this function in two cases:

1. If you are used to working with standard GOST drawings, and, accordingly, better perceive graphics without color content.
2. If you are going to print the results of the calculator. Then you will spend less paint / toner and the visual perception of the drawings on paper will be better. And, of course, this function is used when printing on a black and white printer.

"Change lift direction: LR" function

Rice. 6 View of stairs from different directions lifting

A specific staircase, which is placed in a certain way in the house, can be approached from the side from two sides or only from one side - when the staircase is in contact with the wall. In the latter case, there are two options for placing the structure relative to the observer:

1. Rise from left to right;
2. Climb right to left.

This function allows you to visualize both of these options.

Calculation of winder ladder with 90° turn

The main result of this calculator:

1. Information needed to make bowstrings
2. Information required for the manufacture of steps

According to this information, the parts from which the structure is assembled are made.

All other drawings show the final view of the structure: after joining the bowstrings and steps with each other.

A feature of this calculator for calculating stairs with 90 ° turning steps is the implementation of two functions:

1. Evaluation of the convenience of the stairs;
2. Adjustment of the design of the stairs.

The assessment of the convenience of the stairs is carried out according to three criteria:

1. Compliance with the design of the average stride length. According to this criterion, the sum of step depth and two step heights should equal the average step length. The average human step length is 63 cm.
2. Step depth. Comfortable step depth - from 28 cm. With a given opening length, you can adjust the step depth by changing the protrusion.
3. The angle of the stairs. The optimal angle of inclination of the stairs is from 30° to 40°. At angles of inclination from 20° to 30° and from 40° to 45°, the comfort level of moving between floors is significantly reduced. Inclination angles outside the above limits can significantly affect the speed of movement between floors and the level of safety of the stairs.

Based on the results of evaluating a specific design, an indicator of the level of convenience is issued for each of the criteria, and the stairs are assigned an overall level of convenience. The calculator evaluates whether the stairs meet the well-known criteria of convenience, but you should always remember that your stairs in your home should serve your purposes as efficiently as possible. And if, in accordance with these goals, you need to build the most non-standard staircase in the world - go for it.

If there is a need to improve the design of the stairs, the calculator gives advice on how to do this:

1. Decrease/increase the number of steps;
2. Increase the protrusion of the steps (if the depth of the steps is insufficient for comfortable walking);
3. Decrease / increase the length of the opening.

After the design is adjusted, as well as the exact calculation of the winder steps of the stairs by 90 degrees, the normalized parameters will become closer to the ideal, but such an adjustment may have to be carried out several more times.

Instructions for the calculator stairs with winder steps with a turn of 90 degrees

In order to calculate the stairs with winder steps 90° online, using this calculator, you need to know the height of the floor, the amount of space that you can allocate for the stairs, the materials from which you are going to build it, and, of course, the purpose of its use. Before starting work, it is necessary to carefully consider all the nuances: whether the staircase adjoins the wall, or is in contact with the interior elements of the house, and how this should affect the structure itself and the process of its construction. Perhaps, in order to select the correct option in terms of size and design, you will have to use a calculator to calculate and compare several. Before starting to process the material, make sure that the detail drawings correspond to the ladder that is right for you and your purposes. When building, attach the parts to each other, and the staircase itself to the house so that you can guarantee the reliability and strength of the structure for decades.

The stairs presented on our website can be divided into categories according to three mutually dependent criteria:

1. Length dimension

A. Maximum length - all steps are placed on one pair of bowstrings / stringers;

b. Average length - the steps are placed on two pairs of bowstrings;

V. Minimum length - the steps are placed on three pairs of bowstrings, the length dimension is regulated by changing the number of steps on the corresponding pairs of bowstrings.

2. Width dimension

A. Maximum width - the steps are placed on two or three pairs of bowstrings, the width dimension is regulated by changing the number of steps on the corresponding pair of bowstrings;

b. Average width - the steps are placed on two parallel pairs of bowstrings, the width dimension is equal to two widths of the stairs;

V. Minimum Width- all steps are placed on one pair of bowstrings / stringers, the width dimension is equal to the width of the stairs;

3. The complexity of manufacturing

A. Easy to manufacture - made from bowstrings / stringers and rectangular steps;

b. The average complexity of manufacturing - is made from bowstrings, rectangular steps and platforms;

V. Difficult to manufacture - it is made of bowstrings / stringers, rectangular steps, platforms and rotary steps.

Stairs presented on our website:

• - 1.a.-2.c.-3.a.
• - 1.b.-2.a.-3.b.
• - 1.b.-2.b.-3.b.
• - 1.b.-2.b.-3.c.
• - 1.c.-2.a.-3.b.
• - 1.v.-2.a.-3.v.
• - out of classification
• - 1.a.-2.c.-3.a.

In each specific situation, the height of the floor is already set. Based on your own preferences, you can choose the level of convenience: either the convenience criteria are met, or the stairs are flatter, or steeper, etc. With this information, you can talk about the number of ascents (steps and platforms) in a particular situation.

Imagine that we have, for example, 12 lifts - steps and platforms. The design of the stairs is the shape of these rises (steps, marches, turning steps, platforms) and how these 12 rises are placed relative to each other.

You can place all these 12 rises in one row along the length of the opening - “”, ““. In this case, your staircase will have maximum clearance in length, the minimum dimension in width and will not be difficult to manufacture.

You can place these 12 risers in 2 rows, rotated relative to each other by 90 ° (when viewed from above). With a platform on the turn - “°” - an easier option to manufacture (for example, 5 steps on the lower pair of bowstrings, a platform and 6 steps on the upper pair of bowstrings). With turning steps on the turn - “°” - a more difficult option to manufacture (for example, 3 steps on the lower pair of bowstrings, 3 turning steps and 6 steps on the upper pair of bowstrings). In these cases, your staircase will have an average length dimension and an adjustable width dimension.

You can place these 12 lifts in 2 parallel (when viewed from above) rows placed side by side. With a platform on the turn - "" - an easier option to manufacture (for example, 5 steps on the lower pair of bowstrings, a platform and 6 steps on the upper pair of bowstrings). With turning steps on the turn - "" - a more difficult option to manufacture (for example, 3 steps on the lower pair of bowstrings, 3 turning steps and 6 steps on the upper pair of bowstrings). In these cases, your stairs will have an average dimension in length and an average dimension in width.

You can place these 12 lifts on 3 rows perpendicular to each other (when viewed from above). With platforms on the turns - "" - an easier option to manufacture (for example, 2 steps on the lower pair of bowstrings, a platform, 3 steps on the middle pair of bowstrings, a platform and 5 steps on the upper pair of bowstrings). With turning steps on the turn - "" - a more difficult option to manufacture (for example, 2 steps on the lower pair of bowstrings, 3 turning steps, 2 steps on the middle pair of bowstrings, 3 turning steps, 2 steps on the upper pair of bowstrings). In these cases, your ladder will have a minimum clearance in length and an adjustable clearance in width.

Or you can choose " ", which is not like any of the above and will give the interior of your home a truly sophisticated look, like a spectacular wooden or stylish metal screw.

This design is relevant in a situation where you want a staircase in two spans with a beautiful transition between them in the form of turning steps, and the amount of space in the place where it needs to be placed is limited. Turning steps are not attached directly to the bowstrings, so you will need to provide additional details through which the load from the turning steps would be transferred to the rest of the stairs.

Many private houses, apartments, offices have an unusual layout, or limited space for stairs, which makes it difficult and narrows the choice of its type - standard straight stairs or turning stairs with platforms may simply not fit.

For comfort, a staircase with winder steps was invented, which is easy to adjust to any features of the layout and size of buildings. It saves usable space, looks very elegant, if you comply with all the construction requirements for the width of the steps, then such a staircase with rotary steps is also not traumatic.

• Wall. Thickness.

After that, press the button " Calculate».

If you do not know the initial data that is needed to calculate the 90 ° turntable, you should read the following paragraph, which presents the optimal dimensions of structural elements in private homes. Recommended reading.

We warn you that for the construction of stairs there are certain building codes and regulations governing the methods of calculating loads and strength, dimension, quality of materials, and so on. It is necessary to design a staircase only in accordance with these rules, which include various SNIPs and GOSTs, in order to avoid the collapse of the structure, or its increased risk of injury.

Calculation of stairs online with a 90° turn with a platform on our website allows you to avoid most of the difficulties. Possible mistakes will be highlighted in red in the "Calculation results" block.

For the calculation of wooden stairs, whole “convenience formulas” have been derived. In construction practice, the generally accepted most commonly used parameters for comfortable, durable and safe stairs have been formed. For example, most masters use the well-known formula of the “ideal safe staircase”, which was developed several centuries ago by an architect. François Blondel:

Convenient staircase formula: 2 × h + s = 60/65 cm

• h is the height of the steps;
• s is the length of the steps.

• Ladder angle. Convenient tilt angle wooden stairs between 30-45 degrees.
• Ladder width. Behind optimal size the width of the span of one march in a private house is taken 90-110 cm, with insufficient space in a private house, the stairs can be made narrower, but not less than 80 cm.
• Height and width of steps. According to practice, the ideal step height is in the range of 15-17 cm, the optimal step width is 27-30 cm.
• Thickness of steps, risers and stringers. The elements are made from wooden planks, for risers about 3 cm thick, and for steps - 4 cm, stringers - 5-7 cm.
• Minimum overhang. The minimum step protrusion above the riser is 30 mm, the maximum for a wooden staircase is 40 mm.
• Number of steps. Maximum amount for one flight of stairs - 18 pieces. On average, it is recommended to use 10-12 pieces.
• fences. For safety reasons, the height of the railing should be above 90 cm.

Calculation result

As a result of using our program for calculating stairs to the second floor with a 90 ° turn with a landing, you will receive the following information:

1. Quantity required material, i.e. full estimate for making stairs.
2. The angle of inclination of the stairs, as well as recommendations for optimal height and step width.
3. Stringer parameters for two flights of stairs separately.
4. The length, width and height of the steps.
5. Riser parameters, if you decide to use them,
6. Dimensions of the platform connecting both flights of stairs.

Stair drawing with 90° rotation

Also, the online calculator will prepare for you 4 drawings of stairs with a platform: different kinds on the structure (side, top), drawing of stringers (upper, lower) - all with detailed labels.

3D model of stairs

A 3D model of an L-shaped staircase with a platform on stringers allows a preliminary assessment of the resulting structure in real proportions. Pay attention to the buttons of the tab " View in 3D". With their help, you can enable or disable various elements of the virtual scene in order to design with maximum convenience.

• To zoom in/out the structure, you need to use mouse wheel.
• To rotate the structure - use left mouse button(LMB).
• To change the starting point of view - hold right mouse button(PKM).

If the room has high ceilings, then you should also pay attention to the buildings from a series of steps with a 90-degree turn. To make lifting safer, it is preferable to use an intermediate platform during the construction of structures.

Let's highlight some of the features:

• the space under the steps can be used for your own needs;
• may, if necessary, have entry from any side: ninety-degree stairs are right-handed and left-handed;
• winder steps during the construction of the structure are smaller in height, unlike other types of stairs;
• marches are at right angles, the intermediate platform is executed in the form of a square.

The most commonly used material in the manufacture is wood. In the production of 90-degree wooden swivel stairs, hard rocks wood: oak, ash, beech. Or semi-solid: spruce, larch, pine. wooden structures have always been famous for their elegance. Besides wooden crafts have a beneficial effect on health.

The presented structure, right-handed or left-handed, can be equipped with winder steps. Climbing a winder ladder with a 90-degree turn cannot be called very comfortable, because inner side its steps are less than the outer one. However, the design is elegant and correct location saves a lot of space and will serve for many years.

Calculation of a turntable at ninety degrees

Calculating the dimensions of the finished structure is not an easy task. You can use special mathematical formulas, but it is easier to do this with the help of an online calculation calculator, which can be found on the Internet. You will need the following measurements:

• distance between two floors (from the floor of the first floor to the floor of the second);
• opening length;
• building width.

This is the minimum set of parameters that you will need.
With certain knowledge and skills, you can carry out the calculation yourself. If not, then we recommend using the services of our professional measurer.
