Calculate a modular staircase to the second floor online. Calculation, design and optimal dimensions of stairs to the second floor: how to do it yourself, what to look for

27.06.2020

Specify all required parameters

Y- Opening height.

X- Opening width.

H- The width of the stringer (minimum).

Z— Steps in thickness.

F- The size of the step ledge.

SP- Mark the location of the first step, relative to the floor level surface on the second floor.

The definition of the convenience of stairs is calculated by a formula that is based on the size of a human step.

On average, the stride length varies from 60 to 66 centimeters, and the average value is taken as 63 centimeters.

30° to 40° is the optimal slope of the stairs.

20 -25 cm - optimal height steps.

The calculation of stair steps depends on the height between floors and steps.

Comfortable depth of steps is at least 28-30 cm.

With the help of the protrusion of the step, you can remove the shortcomings of its depth.

Based on the results, the program will draw a drawing with the main dimensions and angles. Our drawing will show all the measurements of the steps, the marking of the stair bowstring in relation to the angle of the step, the top of the steps on the bowstring.

How to make a straight staircase with your own hands

To properly design a flight of stairs, you need to determine the free space where the structure will be located, take into account the height of the rise and the shape of the product, and forget about aesthetics.

March width

This value is not tied to specific figures, only the number of marches will directly depend on the free space.

The smallest width of the march span is exactly 80 cm, if this value is less, then difficulties may arise with lifting furniture, passage for fat people. The optimal width is 100-140 cm.

Building materials for stairs

With the help of our program, you can perform an accurate calculation of a wooden or metal staircase, as well as find out the required amount of material for its construction.

A bar with a section of 50 and a length of 250 mm is ideal for both stringers and bowstrings.

It is better to choose beams for tread with a section of at least 30-40 mm.

Beams for understeps should have a cross section of 25 mm or more.

Beautiful balusters and handrails can be either ordered from a carpenter or bought ready-made, the process of their creation is quite laborious and complicated.

We mount the bowstring (kosoura)

Each beam must be cut on each side, to the length of your stairs. Next, from the bottom of the beam, you need to cut off 5 cm - the thickness of the tread.

In the kosour, we cut openings under our steps. Using a square, mark the width of the treads and the height of the risers, minus 2-4 cm. After that, mark inner surface beams according to our markup.

Using a saw or electric jigsaw, saw off the excess.

We try on the kosour for the future location of the stairs. Each edge of it should fit snugly into the ceiling and the floor surface. We measure the horizontality of each washed down.

We sand the fitted surfaces, if necessary, mill the outer edges.

We mount steps

To install the risers, we saw the beam according to their number. We adjust them and sand them.

Mounting the riser on the kosour

Fastening is carried out from the front side with screws that are puttied.

After mounting the steps, we begin the installation of treads - steps.

We saw the beam into the exact number of steps, minus one. Then we skin each of them and go through all the protruding sides with a milling cutter.

With the help of wood screws we fix the steps on top of the steps.

We mount the balusters on the steps and fix them with studs: 8 millimeters thick and 100 millimeters long.

We attach the railing on top with self-tapping screws.

Now our staircase is installed, and it remains to paint and varnish. Lacquer also allows you to give a protective layer to our product. To preserve the structure of the tree, it is best to use a clear varnish.

Rice. 1 General drawing of stairs

Y - opening height - usually determined by the height of the floors of your house
X - the length of the opening - depends on how much space you can allocate in your house for the stairs
W - the width of the stairs - depends on how much space you can allocate in your house for the stairs
Z - step thickness - geometric parameter material (for example, boards) from which you plan to build a staircase
F - protrusion of steps - the distance by which the upper step will hang over the lower one
A - thickness of the bowstring - a geometric parameter of the material (for example, pipes) from which you plan to make the bowstring of the stairs
B - support thickness - a geometric parameter of the material (for example, pipes) from which you plan to make stair supports
H - the height of the step above the bowstring - the vertical distance between the step and the bowstring
D - size - the distance at which the step will hang over the support in the direction of ascent
U - the angle of inclination of the support to the vertical
C - number of steps - how many steps will you take most comfortably to move from floor to floor

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

Rice. 2 Execution of stairs with the upper step below the floor 2 floors

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

The top plane of the top step is flush with the plane of the floor of the top floor;
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 that in the figure, in which the upper step is below the floor of the 2nd floor, the thickness of the interfloor overlap is greater 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. 2 Black and white drawing of stairs

It is useful to use this function in two cases:

If you are used to working with standard GOST drawings, and, accordingly, better perceive graphics without color filling
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. 4 View of stairs with different directions of ascent

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:

Rise from left to right;
Climb right to left.

This function allows you to visualize both of these options.

Calculation of metal stairs

The main result of this calculator:

Information required for the manufacture of bowstrings and supports
Information required for the manufacture of steps

According to this information, the parts from which the structure is assembled are made, and the calculation of the frame of the iron staircase is also performed.

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

A feature of this calculator is the implementation of two functions:

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

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

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.
Step depth. Comfortable step depth - from 28 cm. With a given opening length, you can adjust the step depth by changing the protrusion. The calculation of the steps of a metal staircase is carried out thanks to a convenient calculator.
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. Slopes outside the above limits can significantly affect the speed of movement between floors and the level of safety of the stairs, as well as the amount of metal used in the work.

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 online metal stair calculator evaluates whether a stair meets well-known criteria for convenience, but you should always remember that your stair in your home should serve your purpose as effectively as possible. And if, in accordance with these goals, you need to build the most non-standard staircase in the world, also with your own hands - go for it.

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

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

After the design is corrected, the normalized parameters will become closer to the ideal, but it is possible that such an adjustment will have to be carried out several more times.

Instructions for the metal staircase calculator

In order to calculate a straight metal staircase using this calculator, you need to know the height of the floor, the size of the 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.

Ladders on metal bowstrings presented on our website can be divided into categories according to four mutually dependent criteria:

1. Length dimension

a. Maximum length - all steps are placed on the same march;

b. Medium length - steps are placed on two marches;

2. Width dimension

a. Maximum width - the steps are placed on two marches, 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 marches, the width dimension is equal to two widths of the stairs;

in. Minimum width - all steps are placed on the same march, the width dimension is equal to the width of the stairs;

3. The complexity of manufacturing

a. Easy to make - made from bowstrings and rectangular steps;

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

4. By the type of bowstrings and the fastening of the steps to them, the stairs are divided into two categories:

a. On supports - the bowstring is a solid beam, to which supports for steps are attached;

b. With a zigzag bowstring - the bowstring consists of many mutually perpendicular parts located horizontally and vertically.

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 lifts (steps and platforms) in a particular situation .

How to calculate a metal staircase in an online calculator with drawings?

Imagine that we have, for example, 13 lifts - steps and platforms. The design of the stairs is the shape of these rises (steps, platforms) and how these 13 rises are placed relative to each other. The calculation of a metal staircase in our calculator is carried out in the following ways.

It is possible to place all these 13 rises in one row along the length of the opening - “Metal staircase”, ““. In this case, your stairs will have a maximum dimension in length, a minimum dimension in width and will not be difficult to manufacture. You can calculate the metal staircase to the second floor using a convenient and intuitive program.

You can place these 13 rises in 2 rows, rotated relative to each other by 90 ° (when viewed from above) - ““, “” (for example, 4 steps on the lower march, a platform and 8 steps on the upper march). In these cases, your staircase will have an average length dimension and an adjustable width dimension. The calculation of the steps of a metal staircase will help to correctly calculate the amount of material that will be needed to complete this work.

These 13 rises can be placed in 2 parallel (when viewed from above) rows placed side by side - “°”, “” (for example, 4 steps on the lower march, a platform and 8 steps on the upper march). In these cases, your stairs will have an average dimension in length and an average dimension in width.

To make the staircase comfortable for use, it is necessary to fulfill many requirements for its design and shape. It is also important to calculate the stairs for safety reasons, because it must withstand all the loads placed on it. Dimensions may vary depending on their location and room parameters. In this article, we will provide you with information on calculating the dimensions of stairs with all acceptable standards.

Why is it necessary to calculate the stairs

During the design phase of a house, a lot of calculations are performed, but we are only interested in those that relate to stairs. The calculation of the stairs to the second floor in an apartment or house must be performed primarily for safety reasons and to save effort and money.

Performing calculations helps determine:

how much material is needed for construction;
what loads must correspond to materials to give the necessary strength to the structure.

Regardless of whether it will be a staircase to the 2nd floor, to the attic, to the basement or viewing hole in the garage, carrying out calculations will help not only do the job correctly, but also protect against injury, eliminating the possibility of structural damage.

How to calculate the stairs to the second floor

The width of the march to the 2nd floor will depend on the functionality of the stairs:

For safe use, the span must be at least 90-100 cm.
To transfer furniture between floors and for a calm divergence of two people in the opposite direction, a width of 125-150 cm is required.

The length of the kosour or bowstring

In order to determine how long the bowstring (kosour) should be, you must use the formula

a 2 + b 2 \u003d c 2,

where a is the length of the march; b - the height of the stairs; c - the length of the bowstring (kosour).

The calculation of the stairs in a private house can be started by determining the number of steps, it will be convenient to use the table below. It shows the dependence of the number of steps on the height of the stairs and risers. Dividing the height of the stairs by the height of the riser, we get a number, rounding which, we get the desired number of steps.

To determine the step width, it is more convenient to use the formula shown in the figure, the dependence of the step width (600-640 mm) and the height of the riser. There are a number of restrictions that must be adhered to when calculating:

the edge of the tread should not hang down more than 50 mm;
the width of the tread should not be less than 100 mm.

The width of the steps based on the formula is: 600 - 2 * 160 \u003d 280 mm.

On what the parameters of the steps can depend

The main parameter on which any straight staircase, turn or spiral depends, is the size of the room in which it is located.

With a not very large area of \u200b\u200bthe room in which it is necessary to fit a straight single-flight staircase, you will have to change the angle of inclination of the structure to a steeper one in order to reduce the length of the bowstring. Changing the angle of inclination directly affects all the parameters of the steps, except for their length, the dependence is shown in the figure.

Features of the calculation of spiral staircases

Principle d is in many ways similar to the calculations of simple mid-flight and turning stairs, but, of course, there are points that should be paid attention to due to design features.

When making a spiral staircase to the second floor with your own hands, you should be aware that there are certain limits in the size of spiral staircases, beyond which it is not advisable to go for reasons of safety and ease of use:

the depth of the step in the middle line is at least 200 mm;
at a distance of 150 mm from the support post at least 100 mm;
in the wide part at the edge no more than 400 mm;
ladder diameter from 1300 to 3300 mm;
march width from 530 to 1430 mm;
opening diameter from 1300 to 3300 mm.

Consider, for example, the calculation of a spiral staircase for a room with a height of 2700 mm and a march width of 1000 mm.

It is necessary to calculate the diameter of the future staircase and, accordingly, the diameter of the ceiling opening. The main thing when calculating to double the width of the march is not to forget to add the diameter of the central support column, with such a width of the march it should be at least 200 mm. As a result, we get: D \u003d 1000 + 1000 + 200 \u003d 2200 mm. This size falls within the parameters described earlier.
Let's determine the radius of the rise, which is equal to the sum of half the width of the march and the radius of the support. Rn=500+100=600 mm. We take half the width of the march due to the fact that in the middle of the span the most optimal tread width is 200 mm.
Knowing the radius of rise Rn=600 mm and the width of the tread 200 mm, we determine the number of steps per one turn of the stairs using the formula: L=2πr/200=2*3.14*600/200=18.84. Rounding the resulting number, we learn that one turn consists of 19 steps.
To calculate the height of a step, it is necessary to determine the distance between the turns of the stairs. Consider an example of the use of stairs by people whose height is not more than 180 cm. In this case, the distance between the turns should be at least 200 cm. Thus, we determine that the height of the steps is 2000/19=105 mm.
The number of steps for our room with a height of 2700 mm is 2700/105=26 pcs.

2000/160=13 pcs

steps, and, accordingly, on the entire staircase:

2700/160=17pcs

This option will be more economical, due to the fact that the entire staircase will require 9 steps less.

Which of the options to use is up to you. The difference is that the ascent of a spiral staircase is steeper than a simple marching staircase, and the use of lower steps makes it easier to climb.

How to calculate the attic stairs in the house

An attic folding ladder is calculated in the same way as a simple attached ladder, based on the fact that the angle of inclination is 65 °. To determine the length of the stairs, you must use the formula:

where c is the length of the staircase, which stands at an angle of 65°, b is the height of the room (in our example, this height is 2700 mm). Using an engineering calculator, we get that c=2700/0.9063=2979.15. Rounding, we get that the length is 2980 mm.

The height of the steps is 25 cm, the width of the stairs, depending on preferences, is 50-70 cm. Information on how to get a folding one from a simple attached attic stairs you can also find on our website.

Using an online calculator for calculating stairs is not at all difficult if you understand the instruction manual and enter it correctly desired parameters. Calculating the stairs to the second floor using a calculator is very simple, and you can do this from any device with Internet access, for example, a tablet, computer, and the like.

The ladder must be strong, stable and properly thought out. In order to determine the size of the stairs in a private house, it is worth considering the space between floors or, in other words, the thickness of the interfloor slab. Initially, you need to decide on the shape of the structure. It is quite possible to equip a building for lifting with your own hands, but in the absence of special professional skills, you should choose the most common version of a straight staircase.

It will be reliable, convenient, and the construction process will not take much money and time. On average, such a staircase is suitable for rooms with a ceiling height of 2.5-3.5 m.

For convenience this subject interior, it is necessary that the flight of stairs be located on racks, and under it there should be free space. Thus, it is possible to use square meters under the shelves, the placement of dark rooms and similar objects. To make the calculation correctly and independently, you need to use a simple and convenient formula, or in other words, just take the optimal proportion - 2/1 relative to the length of the flight of stairs and the height of the room. For example, if the height of the stairs is 3 m, then the length should be 6.

To calculate the slope parameters, you need to rely only on personal preferences. Experts suggest choosing the most optimal tilt angles - 30 and 40 degrees. If the steepness is less, then the size of the length will be very large, and in height it will look short.

What is a ladder calculator online

Now many have begun to use the computer method of calculating the parameters of the stairs online. The program can be installed on an Android smartphone or on a laptop with any operating system. An example of recalculation is in each application together with instructions for using the program.

In general, the development is quite convenient, functional and does not take too much time to calculate the required amount of material, width, including determining the slope.

The calculator table contains various columns and rows, each of which has a specific purpose. There is a calculator that designs the structure. In particular, by entering certain data into the table and pressing the desired button, you can get an image of the future design in a couple of seconds.

The drawing will consist of:

Side and top view;
Step drawing;
Bowstring drawing;
Initial data.

Using the calculator, you can discover many new features that will greatly simplify the development of the project. It is possible to calculate and model a staircase on bowstrings, to carry out the most accurate calculations of structural details, to obtain a diagram of a staircase in at its best and calculate the required amount of materials.

How to calculate the stairs to the second floor in a private house

The methodology for calculating and developing an ordinary staircase is very simple and you can do it yourself. Namely, to design a staircase in your home, you need to accurately measure the ceiling opening. In particular, its width and length, including the height of the ceiling.

Ladder planning should be carried out taking into account:

Dimensions of the future structure;
Interior and general style of the room;
Use of a specific type of materials;
load;
The direction in which the movement will be carried out;
The need to install an additional support.

In any case, regardless of what types of materials will be used, the calculation of the staircase structure is carried out from room measurements. If the construction of the stairs is carried out at the time of repair, then it is worth considering how the room will change, because the walls often thicken, or the ceiling decreases slightly. The dimensions of the stairs can be affected by the finish of the floor, the ceiling and other surfaces in the room.

Key parameters of the staircase calculator

Thanks to modern technical developments, it has become much easier to build houses, determine the location of pipes and stairs in the entrance, and more. Now everyone can independently make a 3D modeling and examine the future staircase almost from the inside.

It is through a computer that you can:

Eliminate errors in the calculation;
Correctly build a ladder, taking into account the norms and standards of SNIP;
Make the stairs comfortable and convenient even at the construction stage.

There are a huge variety of programs and each has its own type of interface, features of entering parameters and the similar characteristics. It is worth noting that improved application models help to calculate even such trifles as the amount of fasteners.

Before you use the calculator to calculate the stairs, as well as to form its drawing, you need to decide:

With the location of the structure in the house;
Overlooking stairs;
With material.

In general, if the project is simple, then the calculation will not take much effort and time, because a direct structure can be installed anywhere in the room.

The standards for the design are the simplest, among which should be taken into account:

Safety;
Reliability;
Convenience;
Comfort.

Even when erecting a staircase in a private house, it should be borne in mind that it will have a great impact. For example, furniture, construction and Decoration Materials and corny will rise a large number of people, children can run and so on. That is why the ladder should be made as stable as possible and preferably with additional props.

For compressed spaces and to save space in the room, you can use a spiral staircase.

It is worth noting that there are also staircase structures, which are divided into two-flight and one-flight. They have large dimensions and are not intended for small rooms. Be sure to think not only the base and the middle of the building, but also the exit to the second floor. The exit or location of the hatch should be convenient so that there are no overhanging structures. For example, the sloping attic roof. This can cause serious head injury and more serious consequences. It is advisable to equip a platform with a railing at the top, which will protect the descent and make it more comfortable.

Rules for using the program: how to calculate the stairs correctly

The calculation of the rise to the top should be the most correct, regardless of what the staircase will be: straight, angular, vertical.

Other parameters are also not so important, for example:

What entrance platform will it be equipped with;
Is it convenient to wash the structure in the future;
The use of which array will be carried out during construction;
Will the structure be wooden or using metal shields.

The most important thing is that the structure must be safe and comfortable, as this can affect the health of those who will use the structure.

For example, stairs that are too steep and slippery steps can cause injury.

It is in order not to spoil the future structure for lifting up that it is worth using special programs that take into account all the nuances, including the size of the march, the height of the opening, and similar parameters.

Calculation of stairs to the second floor: screw design

Spiral staircases can have a rotation of 180 degrees.

These designs:

Stylish;
Beautiful;
Compact.

It is the spiral staircase that is an ergonomic and practical way through which you can get to the second floor from the first. In addition, such structures are often chosen because of their aesthetic appearance, as they will look perfect in modern style or high-tech.

To calculate the diameter of a spiral staircase, you need to multiply parameters such as the width of the march by 2, and then add the diameter of the base.

To determine the radius of the rise, you need to divide the width of the march by 2 and add the radius of the support legs. To make the staircase as comfortable as possible, you should not make it less than 800 mm. Thus, it will be possible to move without problems. With regards to the number and height of steps in a spiral staircase, they must be calculated so that one person can freely climb / descend and, if necessary, turn around on it. The height of the rise space is calculated by adding the average height of a person - 180 cm and the average depth of the tread - 20 cm. Then all this is divided by how many steps one turn has. Then the height of the stairs is divided by the value that is obtained.

Stair calculation program

The formula for calculating stairs depends on the type of structure, height, width, number of steps and material. For a private house, you can choose stairs different kind. In particular, curvilinear, for example, helical, angular and from different material. It can be metal, wood, as well as plastic, but on a wooden or metal base. As mentioned earlier, screw structures are compact in size and add aesthetics to the interior. Also, the calculation of the stairs is affected by the room and its features.

In particular:

What it is used for;
What parameters does it have;
What is the interior in it;
How many turntables are needed;
What should be the configuration of the steps;
Where will the stairs be located?

Stair calculation (video)

Self-erection of stairs is a very interesting activity, because you can connect your imagination, it’s not easy to do metal structure, but the original forged model. There can be a huge variety of options for finishing and construction, but the main thing is to choose only proven methods of calculation. For example, special online calculator.

Any home that has multiple floors requires stairs. For its installation, you need to know how to correctly calculate the stairs to the second floor in a private house. The calculations carried out must be absolutely accurate, otherwise the design will be inconvenient or not at all in the place allotted for it. Therefore, such work should be carried out by specialists or you can use special calculator programs online. In the process of determining the data, materials, dimensions of elements, the slope of the structure, as well as some other data are taken into account.

Calculations by programs

For calculations, a special online calculator can be used, which will help you find out the amount of materials, steps, design slope, bowstring, width. Some programs may provide recommendations on certain parameters of the future design, will report on the possible comfort of using the stairs.

The above parameters affect the convenience and safety of the stairs. At the same time, the minimum height / depth of the steps should be 15/28 cm. It is recommended to make their number odd, then the movement begins and ends with one foot. The height fence is located above the center of gravity of a person’s height, at least 90 cm. The angle of inclination is from 30 to 40 °, for straight stairs, with / without turning steps, the turn can be 90 or 180 °, with several spans and platforms.

In addition to the calculations, the online program will make a drawing of the future design. The required amount of materials depends on the angle of inclination. Therefore, during the design of the house, it is necessary to determine all the parameters.

Online ladder calculator

To find out the approximate cost of a staircase with a straight flight, use the following calculator:

Stair layout

The purpose of the stairs is to move freely between floors. It can carry an aesthetic and design function. When designing it, it is necessary to take into account the materials used, ergonomics, safety, location, area, dimensions and installation. For compliance with all these norms and requirements, a calculator is used. But other technical requirements well known to construction professionals.

Main structural elements are:

Basic structure;

steps ( different shapes);

different number of marches;

fences.

The elements used can be made from various materials, a combination is also often used. The staircase calculator to the second floor in a private house makes it possible to carry out calculations for different types installed structures.

The ladder itself can be of the following type:

On kosoura. The safest, large selection of decorations, concise, with or without risers. Fixing depends on the number of beams.

Turning staircase on a stringer made of metal Source m.yukle.mobi

On the Bolts. Mostly metal, a combination of materials can be used. Fixation with metal elements. Stairs are strong, durable, can be dismantled and reconstructed.

On bowstrings. Have exquisite design, look good in interiors. Fixing steps from the inside.

screw. Occupies a minimum of space, the design includes handrails, racks and steps. They are made round, octagonal or square. The frame is mostly metal.

marching. Have simple design but require a large area of free space. Can be rotary, with platforms.

Carrying out correct calculations is possible only if certain parameters of the structure itself are taken into account. It is necessary to determine the appropriate slope, the width of the structure, the height of the railing and some other indicators. It is important to carry out the correct calculation of the dimensions of the span, which will help to correctly determine the amount of materials. In this case, span and projection dimensions are taken into account. The second important indicator is the length of the openings for the march. It is determined based on the height of the passage, the angle of the march and the thickness of the floor.

Material counting

For the production of stairs are used different variants materials and their combination, but in most cases wood is used. Inexpensive wood is economical, environmentally friendly, affordable and attractive. The tree is easy to process, lasts a very long time, can be painted. Metal structures are fireproof, but can rust due to increased moisture.

The calculation begins with measurements of the height from the floor to the second floor and the area that the stairs will occupy Source pl.pinterest.com

The calculation of a straight staircase is carried out with definition of the following quantities:

ledges steps, their sizes;

overall dimensions opening constructions;

width steps, misdemeanors, kosoura.

After the calculations are carried out, they are displayed on the corresponding drawing.

When working with metal models additional parameters must be taken into account. Some parts are fastened by welding, the material must withstand all loads and be easy to succumb to this procedure. Experts recommend using channels, corners or pipes for stringers. Particular attention is paid to the distribution of the load: the number, area and mass of steps are calculated. Places with increased load must be strengthened with bolts. Can use a combination of materials.

Geometry definition

To obtain accurate calculations, geometric measurements are taken into account, among which the overall dimensions of the entire future structure are important. The minimum width is 1.1 m, including for screw. Options with a width of 1.4 m are considered comfortable.

The angle determines the comfort of using the stairs. Very cool designs save space, but are not convenient. When calculating, it is necessary to take into account the ease of use of the structure, its width and height are determined. Steps at least 15 cm wide. The width of the tread to allow the foot to be completely placed on the square and should be 25-32 cm. The distance between the edges of the steps is determined by their height and width. A special online program will help calculate the parameters of the steps.

Basically, all structures are made with a 45 ° slope, and the width of the steps is mostly equal to the 45th leg size, the minimum is 30 cm. There is a corresponding relationship between the place of attachment of the structure and its steepness, which takes into account the angle, height and length of the projection horizontally. Size dependency analysis can be performed in two ways. In the first case, there is a specific angle, and the calculation shows the place of installation of the structure. In the second, the dimensions of the structure are determined and the angle of inclination is calculated. In some cases, there may not be enough space for a single-flight staircase, then the required amount is added, and the calculations are carried out for everyone separately.

Calculations for various designs

The designer of stairs to the second floor in a private house can be used for various types of future solutions. All options have their own characteristics, they must be taken into account. There are common values that do not change:

With turn and winder steps. In this case, there are some peculiarities, since the staircase has a trapezoidal shape, the rotation can be 90/180 °.

The dimensions of the steps do not change, the calculations for the angle of rotation are carried out in the same way. When determining the parameters, the width of the narrow part and the overhang of the turning step must be at least 10 and 5 cm.

Straight designs. When carrying out the parameters, the dimensions of the opening, steps, the width of the stringer and the location of the first step are indicated.

Two-march, with a turn on the stringers. The rotation can be 180 °, the designs are made as a zigzag or straight. When calculating, the platforms, the height of the floors, the dimensions of the steps and the bowstring, the length of the opening, the slope are indicated.

To find out the approximate cost of a staircase with a 180° turn, use the following calculator:

An example of the calculation of the stairs can be seen in the video:

Three-march with a turn on the stringers. Made with 180° rotation. An important indicator is durability, the load on the structure may vary. Initially, the main indicators of the structure are determined, the height of the march is specified, and then the clearance of the top of the structure. After that, the number of risers and treads is calculated.

screw. The steps are arranged in a circle, inside the support, the radius of the circle is equal to the length of the steps. Absolutely all steps can be swivel, the ratio of the narrow / wide sides is 10/25 cm. The height of the steps is determined similarly to marching structures. During calculations, it is necessary to take into account the dimensions of the span, steps, supports, the shape of the steps (narrow / wide parts 20/40 cm). Maximum attention is paid to the turns of the structure, which should be doubled more value diameter.

Straight on bowstrings. The calculation is based on the length of the step, which will clarify the depth of the steps and the slope. The lack of depth is compensated by the protrusions.

Conclusion

Today, there are various programs for determining the parameters of the future staircase. Specialized resources allow you to visualize structures, create appropriate drawings and get all the necessary information on the dimensions and required materials. But in any case, the final calculation should be performed by a specialist - only then can it be guaranteed that the staircase structure will exactly match all the specified parameters.

Specialized online calculators work according to the formulas embedded in them, which are not visible, which means that you can check the correctness of the results issued only by recalculating everything manually. Therefore, they can only be considered as a convenient tool for preliminary calculations.
