Wooden staircase calculation and drawing. Online calculation of stairs: all the subtleties of calculating complex structures

A properly designed staircase fits perfectly into the interior and is as convenient as possible to use.

The staircase allows access to the upper floors of the building; it is also part of the interior. With its help you can give the room your own special style. You can do the calculation of the stairs to the second floor yourself if you know how.

Calculation of stairs, main points

Is it possible to do the calculations without help? qualified specialists? Can. In order to calculate the stairs to the second floor you need desire and basic knowledge school geometry. Although advice from professionals will not hurt. You can also use special computer programs for calculations.

What is important for calculating a staircase structure? The correct calculation of the stairs is carried out taking into account the layout and size of the rooms. This will affect the choice of location and type of staircase structure. Do not forget that for an interfloor staircase, not only the area on the ground floor is important, but also the ability to provide a convenient staircase opening on the upper level.

Staircase in plan two-story house.

At the first stage, the following points must be taken into account:

height from the first floor to the second (room height);
total area of premises (first and second levels);
location of load-bearing and interior walls;
location of door and window openings.

This will allow you to determine the size of the area that can be allocated for the construction of the staircase, the size of the opening for access to the second floor and select the optimal model.

If the area for installing the stairs measures 160x160 cm or more, then it is better to choose a flight of stairs. If you have a more modest area, you will have to limit yourself to a screw design.

A spiral staircase can be placed in the corner of the room.

Straight stairs

A straight flight of stairs (flight) is the simplest option for installation and calculation. This form is very convenient for wooden structure. Straight flights have one drawback - their installation requires a significant area of the room.

To make efficient use of space, the space under the stairs is often equipped for a closet, offices, and even restrooms.

Generally accepted norms and construction standards will help you draw up a project correctly and accurately perform calculations. For example, if the staircase has an inter-level platform, then its width should correspond to the width of the span. In this case, the minimum width of the flight is 0.7 m. One person can go up or down this staircase.

For comfortable movement of two people, as well as for convenient transportation of large items, such as furniture, to the second floor, household appliances, width flight of stairs should be larger - from 1.2 to 1.4 m.

Addiction bandwidth and the convenience of the stairs depending on the width of the flight.

The length of one straight section with steps should not be more than 3 m (the minimum size is approximately 1.5 m). The steps must be the same height and depth.

Turning stairs

In order to save space in the house, most stairs to the second floor have to be made with turning sections. The easiest way to rotate is to install a platform. There are U-shaped and L-shaped designs figurative forms, where the turn is realized using winder steps.

Important parameters of the stairs that need to be calculated:

inclination angle value;
dimensions of the area between marches;
step height;
depth of straight and winder (if provided) steps;
fencing parameters.

Angle of inclination of flight of stairs

The angle of inclination of the stairs is the angle between the flight of stairs and the horizontal (floor). It is he who is primarily responsible for the convenience of the staircase design. The angle of inclination should allow a person to easily go up/down the stairs.

Depending on the angle of inclination, the staircase is used for certain purposes.

Building codes and rules (SNiP) determine the optimal parameters of stairs: staircase structures with an inclination angle in the range of 30-45 degrees are considered the most convenient and safe. It is these slopes that are chosen for indoor and outdoor stationary stairs. If this angle is less than 20 degrees, install a ramp.

How to calculate stage parameters

When calculating the staircase structure to the second floor, two values are important: the height of the tread and the depth of the tread (the horizontal landing of the step). These parameters determine the degree of convenience and safety when moving (ascending/descending) stairs. It is important to determine them correctly, since these values are involved in the design calculations.

It is convenient to climb stairs when there is no need to artificially increase or decrease the length of the step. The average step length when moving on a horizontal plane is 63-64 cm, and when climbing - 31.5-32 cm.

The step size of the average person.

Based on these data, the height of the riser is most often in the range from 12 to 20 cm (the optimal size is 14-17 cm). The optimal tread depth is determined from 25 to 30 cm. The maximum permissible step depth during the construction of stairs is 32 cm.

Often, in order to save space when installing staircase structures, models are used with one step overhanging the other. This type of steps gives the staircase a lighter and more beautiful look.

Calculation of the size of steps of a flight of stairs

Let's consider the option of calculating the main parameters for simple example. Optimal ratios heights and depths of steps used when designing stairs (cm): 19/27, 18/28, 17/29 and 16/30. Perfect option– 17/29 cm.

We use exactly this ratio to calculate such important design parameters as the angle of inclination, flight length, total steps.

The number of steps is easy to calculate: the height of the floor (for example, 270 cm) must be divided by the height of the step (17 cm): 270/17 = 15.9. We discard the fractional part and get the number of steps on the flight of stairs (15 pieces). If the number is fractional, then you can make the first or last step a little higher or a little lower than the rest.

To eliminate the difference, you can also install a special podium under the stairs.

We specify the height of the steps. To do this, divide the height of the room by the number of steps: 270/15 = 18 cm. Thus, the height of each step is 18 cm.

The depth is calculated taking into account the horizontal step width. For calculation, we select a step equal to 63 cm. From this value we subtract the double height of the step: 63-2x18 = 27 cm.

Calculate the area and angle of inclination

Now you can calculate how much space the stairs to the second floor will take up. It is necessary to determine the area of projection of the flight of stairs onto the horizontal plane. It has the shape of a rectangle, one of whose sides is equal to the width of the steps (d), and the second (b) is the projection of the length of the flight onto the horizontal.

Formula for sparing a rectangle: S = b x d.

The length of the larger side of the rectangle (b) is obtained by multiplying the depth of the steps by their number: 27x15 = 405 cm. The smaller side of the rectangle (d) is equal to the width of the stairs and is selected independently. It is worth considering that the minimum size for one person to move is 70 cm, for two people the minimum is 100 cm.

For convenience, the staircase in the drawings should be presented in 3 projections.

Now you can start calculating the length flight of stairs. In this simple calculation, the well-known school formula(Pythagorean theorem). The length of the march is the hypotenuse right triangle(c), the legs of which are the height of the room (a) and the horizontal projection of the span (b):

c2 = a2 + b2 = 2702+4052

And the required length (hypotenuse) is equal to square root from the sum of the squares of the legs, i.e. c = 486.7 cm or 486 cm (we do not take into account the fractional part).

To determine the angle of inclination of the stairs, you will have to remember school course trigonometry: the sine of the desired angle is equal to the ratio of the height of the floor (a) to the length of the flight of stairs (c):

cos(α)=a/c, α = arcos(a/c)

Having performed calculations using these formulas, we determine the angle of inclination - 370.

Convenient service for calculating staircase structures

Walling

When developing a design for a staircase to the second floor, it is worth paying attention to the fence in order to install it correctly. The following dimensions are important for installation:

baluster height;
length and width of the railing.

The fences are important element. Their standard height(including handrails) should be from 90 to 100 cm. If there are children in the house, additional handrails should be provided (70-75 cm). The design and material of the fence can be anything.

For stair railing Not only reliability is important, but also convenience.

If you build a staircase according to all standards and rules, then it will be comfortable, durable, safe and will last for a long time.

Independently designing a dacha or Vacation home, you will definitely have to face the problem of calculating the stairs. The task is not that difficult, but basic techniques for calculating different types you should know the stairs.

What parameters does the calculation technique depend on?

To perform the calculation you need to decide:

with the type of construction;
tilt angle;
number of steps;
width of steps;
other design features.

First of all, you will need the following parameters:

Height of the stairs.
Availability of sufficient space for a certain type of structure.
The type of material used to construct the stairs.
Operating conditions depending on family composition. If there are elderly people, then there is a steep climb, they simply cannot overcome it. This design is also dangerous for small children.
Is it planned to carry heavy, large furniture up the stairs? Screw design completely excludes this possibility.

First of all, you need to decide which staircase specifically you want to see in your home, and only after that enter the data for calculation. You will have to choose among these types:

screw with steps located around the rod in a spiral;
zabezhnaya, where there is no intermediate platform;
straight with a turn of 900 with an intermediate platform;
with a 180° rotation with the obligatory presence of an intermediate platform.

You should also take into account such nuances as the location of walls, partitions, doorways, area of the room, distance between the ground floor floor and the ceiling.

The staircase is straight, made in the Art Nouveau style. Its cost is within 116 thousand rubles.

Staircase in the "Modern" style, turning, costing 120 thousand rubles.

Calculation of the stairs to the 2nd floor using an online calculator

There are many online calculators on the Internet that make the task of calculating stairs as easy as possible and quickly resolve all issues.

The basis for programs for online calculators are the requirements for staircase structures and standards regulated by GOST. An example of one good calculators- zamer-doma.ru.

It works simply, just enter data such as the height, length of the opening, number, thickness of steps, height of their edges, maximum width of the stringer, as well as the direction of rise and orientation of the first step relative to the floor of the 2nd floor to get:
staircase drawing;
length of the upper bowstring;
angle of inclination of the structure;
the size of the step between cuts under the steps on the bowstring;
height and depth of steps;
height of the riser;
recommendations for changing parameters to improve the comfort of the stairs.

Another free online calculator is lestnicmir.ru. With its help, you can calculate the most appropriate design and receive recommendations for improving its ergonomics.

To do this, you only need to select the type of staircase, enter the required dimensions and data on the steps, the calculator will do the rest itself.

A good staircase calculator domaizbrusa-pestovo.ru. It is easy to use - you just need to pay attention to the prompts and enter the parameters required by the system.

This online service allows you to perform structural calculations. There is also a material calculation calculator here.

The program will also produce a drawing of the staircase, where the main dimensions will be indicated, the markings of the upper points of the steps on the string, the angles at which the steps are located relative to the string, and other defining dimensions.

Formula for calculating the convenience of stairs

Sometimes online programs to calculate staircase structures, they give a verdict that a staircase made according to the dimensions you entered will be inconvenient.

You can draw such conclusions yourself by making a simple calculation based on the average step length.

Usually a person takes a step with a length of 600-660 mm, which means the average value is 630 mm. Options convenient design must correspond to the following formula:
2h + S = 630±30 mm, where:

h – step height, varying between 200-250 mm;
S – its depth, corresponding to foot size 45, which is from 280 to 300 mm.

As for the most convenient tilt, it is 30-40°.

Disadvantages in the depth of the staircase are easily eliminated by using a ledge.

To obtain accurate data, measure all parameters entered into the online calculator program with one tool.

When determining the main dimensions of steps, you can use a table compiled by specialists based on own experience and regulatory requirements:

Symbol of the required parameters of a straight wooden staircase

Usually in online calculator the parameters are designated as follows:
Y is the height of the opening.
X is the width of the opening.
H - minimum stringer width
Z is the thickness of the step.
F - step protrusion.
SP - location of the 1st step, relative to the floor on the second floor.

Online staircase designer program

There is a Consultec Staircon program, developed in Sweden, which can be used not only to calculate the staircase to the second floor, but also to create its design in 3D format. And in addition:

By entering parameters such as the width, height of the staircase, the number of steps and turning platforms, you can build a very accurate drawing.

Choose a fence.

Select the material for the staircase as a whole or for its individual elements.

Select a finishing option.

To develop a project, it is convenient to use the Mastercam program, which allows, among other types of work, to simulate flights of stairs. There are many similar developments, but not all can lead to a finished result. Program online constructor allows you to select the parameters of enclosing structures
After creating the project and calculating the stairs, you can place an order on the website. Technical equipment Our production allows us to reduce costs, reduce the production time of stairs with their consistently high quality.

Avoid differences in height of stair steps. They should all be exactly the same.

The width of the landing should be equivalent to the width of the flight.

A straight fragment with degrees of length should not be less than 1.5 m and not exceed 3 m.

The size of the steps depends on their number.

The minimum width of the stairs is 0.7 m, which ensures passage of 1 person.

The formation of the angle of inclination depends on the parameters of the steps, but it must ensure proportional movement of the person forward.

A staircase with a greater angle of inclination takes up less space, but it is more difficult to climb it.

Ideally, the width of the railing should be equivalent to 10 cm.

The optimal height of the railing is 90 cm, and the height of the baluster is 80 cm. Moreover, if it is intended to be installed in a groove, then this figure is slightly increased by adding the depth of the groove.

The height of the support posts must be equal to the corresponding size of the balusters, but if they are installed not on the steps, but on the floor, then the distance from the steps to the floor is added to this height.

The length of the railing and flight of stairs are equivalent to each other.

Proper calculation will save you from mistakes and unnecessary rework, saving time and money.

Using an online calculator to calculate stairs is not at all difficult if you understand the operating instructions and enter the necessary parameters correctly. It is very simple to calculate the stairs to the second floor using a calculator, and this can be done from any device with Internet access, for example, a tablet, computer, and the like.

The ladder must be strong, stable and properly designed. In order to determine the size of the stairs in a private house, it is worth taking into account the space between floors or, in other words, the thickness of the interfloor slab. First you need to decide on the shape of the structure. It is quite possible to equip a structure for lifting with your own hands, but in the absence of special professional skills, you should choose the most regular option straight stairs.

It will be reliable, comfortable, and 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 the convenience of this piece of furniture, it is necessary that the flight of stairs be located on racks, and there should be free space under it. Thus, you can use square meters under shelves, 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, simply 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 length will be very large, and in height it will look short.

What is an online staircase calculator?

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

In general, the development is quite convenient, functional and does not require too much time to calculate required amount 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 clicking on 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 views;
Drawings of steps;
Bowstring drawing;
Initial data.

Using the calculator, you can discover many new possibilities that will greatly simplify the development of your project. You can calculate and model a staircase on bowstrings, make the most accurate calculations of design details, get a diagram of the 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

Calculation and development methodology ordinary stairs It’s 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.

Planning of the staircase structure should be carried out taking into account:

Dimensions of the future structure;
Interior and general style of the room;
Usage specific type materials;
Load;
The direction in which the movement will take place;
The need to install additional support.

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

Key Parameters of the Ladder 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 anyone can independently make a 3D simulation and examine the future staircase practically from the inside.

It is through a computer that you can:

Eliminate errors in calculations;
Build the stairs correctly, taking into account the norms and standards of SNIP;
Make the staircase comfortable and convenient even at the construction stage.

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

Before using the calculator to calculate the staircase, as well as to generate its drawing, you need to decide:

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

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

The design standards are the simplest, among which the following must be taken into account:

Safety;
Reliability;
Convenience;
Comfort.

Even when erecting a staircase in a private house, it is worth considering that it will be subject to great impact. For example, furniture, construction and Decoration Materials and it will simply rise a large number of people, children can run around and so on. That is why the stairs should be made as stable as possible and preferably with additional supports.

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

It is worth noting that there are also staircase structures that are divided into double-flight and single-flight. They are large in size and are not intended for small rooms. Not only the base and middle of the building, but also the exit to the second floor must be thought out. The exit location or location of the hatch should be convenient so that there are no overhanging structures. Eg, sloping roof attics. This can cause serious head injury and more serious consequences. It is advisable to arrange a platform with railings 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 kind of staircase it is: straight, angular, vertical.

Other parameters are also not so important, for example:

What kind of entrance platform will it be equipped with?
Will it be convenient to wash the structure in the future?
What kind of mass will be used during construction;
Will the structure be made of wood or using metal panels?

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, too steep stairs and slippery steps can cause injury.

It is precisely in order not to spoil the future structure that you should use special programs, in which all the nuances are taken into account, including the size of the march, the height of the opening and similar parameters.

Calculation of the stairs to the second floor: screw design

Spiral staircases can rotate 180 degrees.

These designs:

Stylish;
Beautiful;
Compact.

It is the spiral staircase that is ergonomic and in a 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, since they will look perfect in modern style or hi-tech.

To calculate the diameter of a spiral staircase, you need to multiply parameters such as the width of the flight by 2, and then add the size of 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 support posts. To make the staircase as comfortable as possible, you should not make it less than 800 mm. This way, you can move around without problems. Regarding the number and height of steps in spiral staircase, they need to be designed so that one person can freely ascend/descend and, if necessary, turn around on it. The height of the approach space is calculated by adding the average height of a person - 180 cm and the average depth of the tread - 20 cm. Next, all this is divided by how many steps one turn has. Then the height of the stairs is divided by the resulting value.

Staircase 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 various types. In particular, curved ones, for example, helical, angular and different materials. It can be metal, wood, or plastic, but on wood or metal base. As mentioned earlier, screw structures are compact in size and add aesthetics to the interior. The calculation of the stairs is also influenced by the room and its features.

In particular:

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

Calculation of stairs (video)

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

In order to perform calculations of the future staircase data with your own hands, you will need to find a number of parameters. If you do not know the basic design rules, you can make serious mistakes, which will further affect the safety and convenience of the design. To make the task easier, we introduced standard specifications and special formulas have been developed.

Types of structures

straight one-march;
single-flight with winder steps;
two-flight with an intermediate platform;
rotatable 90 degrees (L-shaped);
swivel 180 degrees (U-shaped);
with an arbitrary degree of rotation.

For a beginner, doing your own calculations of staircase parameters may seem like challenging task. In order to avoid significant mistakes, you need to familiarize yourself with the basic indicators, established standards and formulas for calculations.

Options for staircase designs to the second floor

SNiP standards

Before calculating stairs for climbing to the second floor, you need to familiarize yourself with the SNiP and GOST standards. If you decide to completely make the entire structure with your own hands, this step is mandatory.

First of all, you should pay attention to the following parameters:

Slope. Reflects the angle of inclination of a flight of stairs; for residential premises this indicator should be within 30-40 degrees.
Number of steps. The exact value depends on the length of the span and the number of flights, minimal amount is equal to three, the maximum is 16 for double-flight models and 18 for single-flight models.
Site size. If a two-flight structure with a platform is installed to ascend to the second floor, the width of the latter must be no less than the width of the flights leading to it.
Tread width. Distance from the edge of the step to the riser, optimal distance-29 cm, fluctuations +/-3 cm are allowed.
Riser height. The distance between steps is considered to be 17 cm as a standard, however, the interval of 14-20 cm does not go beyond the norm.
Step. The total distance covering 2 treads and 1 riser, the ideal value is 62 cm.
Width of the stairs. The distance from one edge of the step to the other, for a regular staircase to the second floor, is at least 80 cm.
Dimensions staircase. The area of the cage must be sufficient to allow the door to be opened or the person to pass without hindrance.

If the staircase meets all the standards described above, it will be safe and very convenient for movement.

Calculation scheme optimal angle stair inclination that meets standards

In some cases, in particular when the house has already been built and it is not possible to make changes regarding the height of the floors and the layout of the room, deviations from the standard indicators are allowed, the main condition is that the changes made should not seriously affect the safety indicator of the staircase structure.

Opening and dimensions of steps

You can calculate stairs, or rather, steps, only if you have all the formulas available and defined basic indicators. To begin with, they are selected intuitively, based on SNiP standards. You also need to measure the opening; in the future, you can adjust the parameters if some deviations and discrepancies are identified. Since you can calculate the dimensions of the opening for the stairs using a simple tape measure, first measure the distance from the floor to the ceiling, and from the entrance to the second floor to the position of the first step.

In order to calculate the staircase in the house, as well as determine what size the opening should be, you first need to know the number of steps in the flight. Based on this indicator, you will calculate the size of the riser and can use the formula to determine the step. So, let's look at how to calculate the standard stair step. To do this, you need to take the width of the tread and the height of the step. The formula for calculating the step of the stairs is as follows:

2a + b = 60…65

In one step, a person can cover an average of 60-65 cm. This is a comfortable step size, on the basis of which you can calculate the width of the tread (a) and the height of the riser (c).

Measurements necessary for the correct calculation of the stairs to the second floor

These indicators can also be determined in a slightly different way. To do this, you need to take as a basis such parameters as the height of the rise, the length of the projection and the slope of the stairs. First you need to calculate the lift height:

h = H + D

In other words, you need to sum up the height of the room and the thickness of the ceiling. From here you can find out the number of steps:

Based on the number of steps and the height of the tread, you can calculate the projection length of the staircase, focusing on the opening. We calculate the projection length of the stairs:

If you know the height of the rise and the length of the stairs, you can find out the slope or steepness of a straight staircase:

Based on these data, you can calculate more accurate indicators for a straight staircase:

a = h/n

Convenience and safety

In addition to the dimensions of the structure itself for lifting to the second floor, there are several more criteria for assessing convenience and safety that must be taken into account. Therefore, it is not enough to simply correctly calculate the stairs using the specified formulas; it is necessary to determine the degree of compliance of the design parameters with the required standards. This can be done with your own hands using simple techniques.

Calculation of a safe and convenient step of stairs for private use

First of all, the formula is used to calculate the safety of the stairs:

a + b = 46

This sum of the dimensions of the tread and riser indicates that the preliminary calculations were made correctly and comply with the standards.

There is also a special formula for determining the degree of convenience of the stairs:

a – b = 12

If the difference between these two indicators is 12 units, it means that climbing such a staircase to the second floor will be very convenient for the average person. The opening must also meet the requirements of convenience and safety, provide free access and not impede access to the second floor.

You should not recalculate the entire project if there are minor deviations of a couple of centimeters, this is quite acceptable.

Winder steps, platforms and cages

Separately, it is worth considering the situation with the design of a non-standard staircase structure. So, let's figure out how you can calculate the stairs yourself if you plan to use a winder structure to climb to the 2nd floor. Standard formulas are only suitable for straight marching models. Here's the size calculation winder staircase produced graphically. In this case, the calculation of the staircase and intermediate landings is carried out separately, if any.

Schematic representation of the design of a staircase with winder steps

Let's look at how to calculate a two-flight staircase in a house with your own hands. If an intermediate platform is used, the calculation of such an interfloor staircase is carried out in two stages. First, the position of the site or intermediate cell is calculated. Then, up to this mark, the parameters are calculated for the standard march, and then for the second similar section. The dimensions of the staircase are calculated based on the width of the last step leading to the second floor and the dimensions of the passage.

Now you know how to correctly calculate the stairs in the house and the opening for it. If you are experiencing some difficulties with design, you can use online programs, but you should not trust them one hundred percent, calculation of stairs – This is a very important stage and in this case it is better to order finished work from a professional.

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

Calculations by programs

For calculations, you can use a special online calculator, which will help you find out the number of materials, steps, slope of the structure, string, width. Some programs can provide recommendations regarding certain parameters of the future design and will indicate the possible comfort of using the stairs.

The convenience and safety of the stairs are influenced by the parameters listed above. In this case, the minimum height/depth of the steps should be 15/28 cm. It is recommended to make them an odd number, then the movement begins and ends with one leg. The height of the 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 or without turning steps, the rotation 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 structure. The required amount of materials depends on the angle of inclination. Therefore, when designing a house, you need to determine all the parameters.

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

Staircase layout

The purpose of the staircase is to allow free movement between floors. It can have 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. A calculator is used to ensure compliance with all these standards and requirements. But others need to be taken into account technical requirements, which experts in the construction industry are well aware of.

Main structural elements are:

Basic structure;

steps ( different shapes);

different quantity marches;

fencing.

The elements used can be made from various materials, 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 staircase itself can be of the following type:

On the stringers. The safest big choice decoration, laconic, with or without risers. Fixation depends on the number of beams.

On the Bolts. Mostly metallic, a combination of materials may be used. Fixation metal elements. The stairs are strong, durable, can be disassembled and reconstructed.

On the bowstrings. They have an elegant design and look good in interiors. Fixation of 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 large area free space. They 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, width of the structure, height of the railing and some other indicators. It is important to correctly calculate the span dimensions, which will help to correctly determine the amount of materials. In this case, the span dimensions and projections are taken into account. The second important indicator is the length of the openings for the march. 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 they are used different variants materials and their combination, but in most cases wood is used. Inexpensive wood is economical, environmentally friendly, accessible and attractive. Wood is easy to process, lasts a very long time, and can be painted. Metal structures are fireproof, but can rust due to increased moisture.

The calculation begins with measuring 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 using determination of the following quantities:

projections steps, their sizes;

general dimensions opening designs;

options stairs, handrails;

width steps, misdeeds, stringers.

After the calculations have been made, they are displayed in the corresponding drawing.

When working with metal models, additional parameters must be taken into account. Some parts are attached by welding; the material must withstand all loads and be easily amenable to this procedure. Experts recommend using channels, corners or pipes for stringers. Special attention is paid to load distribution: the number, area and mass of steps are calculated. Places with increased load must be reinforced 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 ones. Options with a width of 1.4 m or more are considered comfortable.

The angle determines the comfort of using the stairs. Very cool designs save space, but are not convenient. When making calculations, it is necessary to take into account the ease of use of the structure; its width and height are determined. The steps are at least 15 cm wide. The width of the tread allows the foot to be completely placed on the area 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 you 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 foot size, the minimum is 30 cm. There is a corresponding relationship between the place where the structure is attached and its steepness, which takes into account the angle, height and length of the horizontal projection. Size dependence analysis can be performed in two ways. In the first case, there is a specific angle, and the calculation shows the location 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 area for a single-flight staircase, then the required number is added, and calculations are carried out for everyone separately.

Calculations for various designs

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

With turn and winder steps. This case has its own characteristics, since the staircase has a trapezoidal shape, the rotation can be 90/180°.

The dimensions of the steps do not change; 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.

Double march, with a turn on stringers. The rotation can be 180°, the designs are made as zigzag or straight. When calculating, the platforms, floor heights, sizes of steps and strings, opening length, and slope are indicated.

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

Video description

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

Three-march with a turn on stringers. Made with a 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 flight is specified, and then the clearance of the top of the structure. After this, the number of risers and treads is calculated.

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

Straight on bowstrings. The calculation is based on the step length, which will allow you to clarify the depth of the steps and the slope. What it lacks in depth, it makes up for in 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 obtain all the necessary information on dimensions and required materials. But in any case, the final calculation must be carried out by a specialist - only then can it be guaranteed that staircase design will exactly correspond to all specified parameters.

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