Online calculation ladders, drawings, diagrams, design options

In order to make their homes as comfortable as possible, do not just hire the builders, but also yourself to delve into the engineering calculations. The basic modular design house - stairs. It is this that gives the interior a unique luxury that many dream. There are various ways to arrange staircases and install steps. Online calculation of the stairs will help to design the optimal design and calculate the amount of material.

Ladder in a private house as an important element of planning convenience

Staircase design helps to bind not only the private house floors, but also two-level apartments. That is, it can become the central link Hall first floor. In addition to aesthetics, it should be comfortable, safe and durable.

About the location of staircases need to think at the stage Housing planning or apartment. This will depend on the direction of the main premises: hall area second floor, Location, and the appointment of the other rooms. You can intelligently equip the space around the staircase to the first and second floors.

At a central location structure is preserved the symmetry of space and comfortable passage from every room of the first floor. It is now home decoration. You can think improvement is quite exquisite. In the area of ​​the hall is a place for relaxation or entertaining room. On the second floor there will be enough space for a comfortable passage to the Bedroom.

If the structure is disposed of hall - this will release the usable area, which can be consider as a dining room on the ground floor or the sports area - on the second. On the walls along the march post interesting decor or art gallery.

Various kinds of design stairs: Photo gallery

Accommodation options and execution of stairs a lot. You can pick up an interesting design easily, which will make the interior a personal and unique.

wooden stairs perfectly combined with glass railings. Wrought iron designs require a more cautious approach. As can act as a natural complement to the interior a rock, Ceramic or glass.

We offer a look at examples of wooden staircases in interior of the house. In the photo you can see that they are quite useful floor area:

Wooden buildings with a platform significantly saves space:

Screw design can be a real interior decoration:

Glass It can also be a good choice for ladders:

Metal constructions have increased durability and reliability. They can be combined with both wood and glass:

construction of concrete may become a central element of the hall:

It is important when planning the design of stairs to take into account the age of living. If you have young children, the main criterion - the safety of both the structure of the steps and railing. Older people will be difficult to get used to screw design, the slope must be performed less steep.

Definition of the main technical parameters for online calculation ladders

Construction of stairs - this is not the flight of designer fantasies. Developed certain standards tradeoffs, load capacity, compliance with which is important primarily for the safety and comfort of movement around him. Slight deviations are permitted within limits, otherwise the design will be a danger to humans.

Before you calculate the stairs to the second floor, it is necessary to define the basic parameters:

• lift height (substep);
• the width of the tread (step);
• stairs bias.

the slope angle of 45 ° is considered to be cool, this design is not suitable for every family or for everyday use. However, if the layout or area of ​​the house does not allow the installation of a different design, it is necessary to consider safe railings for ease of walking on stairs.

It is interesting! The slope of the stairs - is the ratio of lift height to the width of the stair. The broader step, the less will be a steep flight of stairs.

Besides the basic parameters for the ladder structure are also affected by:

• the length of the flight of stairs;
• Sizes stairwells;
• the distance between the marks clean floor 1 and 2 of floor;
• the number of stages. Regulatory documents defined by 3 to 18 units.

Deviation from standard or acceptable parameters at best cause discomfort when moving. In the worst - can cause a number of diseases.

The main types of ladders

Stairs in the room can be made in the following variations:

• flight of stairs;
• Coil;
• combined version.

The choice depends on the size and layout of premises. Important role in the interior of the house it would take, depends on the feasibility of installing a particular model.

Let us consider each design.

Flight of stairs

This design has improved reliability and simplicity of execution. Depending on the room height and width of the steps you can install one or more marches. The number of steps in each should not exceed 16.

Stairways can be classified by the following features:

Screw

It involves the installation steps in a spiral around the main axis. Such a structure can be installed in order to save the living space. It will not take more than 1 m². The main feature of the spiral staircase - the ability to install almost anywhere in the room. It consists of construction steps, supports, handrails and balustrades.

Since its installation, the interior is transformed in the performance of a completely unique design. It may seem completely weightless. For example, glass stairs with wooden railings and aluminum balusters. Pick up the material can be under any stylistic direction of the room.

combined

Combined called arched ladder. It combines elements of a helical structure with a flight of stairs. To install it is necessary to allocate a certain area. Items can be carried out in the form of straight sections, in the form of an ellipse, circle or semicircle.

Main materials used for manufacturing ladders, and the nuances of their calculation

The material from which to make a ladder, must fit into the interior and meet all safety requirements. When you select it is necessary to pay attention to the origin and environmental friendliness, and certificate validation material for compliance with quality standards.

The most frequently used:

• wooden structures;
• metal ladder;
• concrete bases;
• glass;
• plastic parts.

Combination embodiments can be incorporated into the design. For classical interiors or ethno-style suit wood, Gothic forging will look appropriate. In modern ways you can use stainless, Nickel-plated or galvanized steel in combination with aluminum or glass.

Calculation of wooden stairs

The base structure is subjected to a greater load, so solid woods are suitable for him. For fencing elements can select the material of medium hardness, or soft variety, it is easier to handle.

The following parameters are required for the calculation of the staircase of wood:

• Room height (from floor to clean the ceiling);
• aperture length (measured from the horizontal projection length of the opening edge to the first tread);
• number of steps;
• Human srednestaticheskogo pitch width;
• the width of the flight of stairs, with the optimal size guardrails - 100 cm;
• depth step;
• step height (buttress);
• the height of the fence, with the handrail should be about 100 cm;
• thickness encamp - this parameter depends on the type of tree.

One of the main parameters of the calculation is the thickness kosoura which takes the main load. The steps in the wooden structure can be performed with or without projection. It is up to personal preference.

Calculation of metal stairs

Metal ladder design is made of channel, of corrugated metal steps steel "fillies" and brackets. The elements are fixed by welding. Calculation of the elements is performed according to the general formula given room ascent and descent.

Furthermore, for the construction of metal necessary to calculate the strength and stiffness parameters:

1. Useful regulatory load on 1 square. m ladder considered 300 kg. Should be considered when calculating the overload coefficient equal to 1.4;
2. When calculating load on the handrail should be considered overload coefficient 1.3 to the standard parameter of from 50 to 100 kg of 1 meter.

When calculating the flight of stairs takes into account the distance between the opposite walls. They need to plan for more than 20 centimeters of width of the march.

Determining the required geometric dimensions stairs

Before starting the construction of settlements is important to consider the geometric parameters of the room:

• distance from the floor level 1 and 2 of floors;
• layout design features walls;
• site installation of doors and windows;
• floor area;
• layout of the house.

Perhaps, when performing the calculations need to be amended in particular installation and repair of premises.

Calculation of stair steps sizes in a private home with the help of online calculator

First of all, you need to perform the calculation steps of the staircase so that their height is the same. The width of a flight of stairs must not be different from the width of the platform. march length should be in the range 1,5 ÷ 3 m.

• step size depends on the length of the flight of stairs and the number of stages. When the width of the calculation takes into account the total capacity, the standard is considered to be 0.7 to 1 m;
• step height is also calculated taking into account the comfort of ascent and descent. Optimal height - 12 ÷ 20 cm;
• stage depth depends on the size of the human foot. Standard parameters considered from 28 to 30 cm;
• to calculate the number of steps necessary to divide the stair height to the height of steps, which should be selected from the table based on a comfortable angle of inclination of the design. If not get even, adjustment should be made on the size of the first stage.

It is considered that the width plus the height of two stages of steps must be in the range of 60 ÷ 64 cm. This is the most comfortable size ladder steps for lifting and lowering. When planning the construction with marches disposed in the opposite direction, it is necessary to leave an opening of at least 50 cm between them.

Calculator for determining the optimum angle of inclination of the ladder

Relaxing angle depends on the height and width of the stair step. It is calculated in such a way that when a man walking in proportion to move forward. It assumed a comfortable angle within the 23 ÷ 37 °.

It is important! The smaller the angle, the more area required for the mounting structure. However, the increase in the angle will cause discomfort when climbing to the second floor.

If the inclination angle is less than the recommended parameter can be set ramp. This will save space and make the descent and ascent more comfortable.

Online calculator for stairs: drawings and diagrams

To calculate the stairs to the second floor, you can use an online calculator or resort to a simple formula, the French architect Francois Blondel. It shall be based on the width of a human step, which we mentioned earlier.

S = A + 2×H or two steps to fold the width to the height of the tread.

The necessary security:

A + H = 46 cm;

Formula amenities:

A - H = 12 cm.

parameters of the safest ladders can be calculated thanks to this magic formula. Before starting calculations offer watch a video, which describes in detail the basic errors ladders design.

With zabezhnymi steps rotated by 90 °

Design with zabezhnymi steps can save area, the functionality will be preserved. The optimum amount of rotational elements - 3 for opening width of 80 cm. A larger number of stages is narrow and uncomfortable. For wide design allows the installation of a larger number of winders.

It is important! If the rotary member is installed in the upper part of the march, it is necessary to take into account the height of the portion in order to avoid injuries of the head. Optimal height - 2 meters.

The calculation is performed taking into account the human srednestaticheskogo step 60 ÷ 64 cm. width sum of two steps and a height should be within these limits. The calculation can be performed using the stairs online calculator, which you must specify the source data.

Online calculator calculating ladder rotated 180 °

When calculating the rotation through 180 ° is necessary to consider the following factors:

• width winder stage at its narrowest point should not be less than 14 cm, wide - 40 cm;
• design turning radius - 30 cm;
• there should be no differences of heights, the height of all steps should be the same for comfortable movement;

Winders can start to perform a straight portion. When online, you can calculate the stairs and find the optimal parameters of steps a special program.

Calculation of straight stairs online calculator

Fixing direct marches most often performed on kosour. This oblique beam that serves as a support for a ladder. Steps are superimposed and fixed from above unlike installation on the string. Stringers can be straight, broken and screw.

Direct stringers are used for fastening staircases in one pass with a central or lateral position. Kosour takes care of all the main load. Therefore, the correct calculation depends for its safe operation, durability and stability of the entire structure. Most often used kosour of wood or metal.

To calculate the wood element is necessary to determine the distance between the marks clean floor 1 and 2 floors and the length of the flight of stairs, which is determined by multiplying the number of steps to the width tread. If the last step is performed at the level of 2 floors, it should be excluded from the calculation.

The formula for calculating the length of the flight of stairs:

C = √ (H² + L²),

In other words, the size kosoura is the square root of the sum of squares of the room height and length of the march. element calculation can be performed using an online calculator. Enough to supply the required cell parameters.

Half-pace model kosour rotated 180 °

If the inclination angle exceeds 40 °, it is recommended to perform a half-pace model with one platform. It is necessary to move at the appropriate level between the floors.

Run such a structure is possible in two ways.

• Staircases combined platform whose width is equal to the sum of the width of the march and partition between constructs. Platform length - not less than ½ of its width;
• zabezhnymi structure with steps, wherein the pad is replaced with several trapezoidal steps.

Trehmarshevaya model kosour rotated 180 °

Trehmarshevaya rotated by 180 ° is performed at two sites.

If the slope is rather large, it is possible to perform marches with two pads and rotated by 180 °. Moreover, it will save a useful area.

The calculation program will select the best option, you can play with the calculations and the number of steps on each march. It is important to bear in mind that the width of the site should be similar to the width of the opening.

It should know! Professionals advise to do the odd number of stages to the beginning and end of the ascent or descent on each march is always carried out with the support legs.

The minimum number of steps in one march should be at least three. The height of the fence or railing should vary in the range of 90 ÷ 110 cm.

Calculation of the spiral staircase

spiral staircase structure is made such that the step width is reduced toward the center. Wide side they are fixed to the balusters or to the walls, narrow - to the central post. For such a design optimum maximum width should be 40 cm, the center - 27 ÷ 28 cm.

Featured travel schedule person must span the width of each of the sides - 100 ÷ 50 cm, or on the entire structure should be given distance of 100-200 cm.

To perform the calculation with their own hands the spiral staircase to the second floor, the following parameters will need:

• place the central support assembly;
• span width (distance between the central and side legs);
• form of steps (it is necessary to calculate the optimum length to the width of one side over 40 cm, a narrow edge should not be less than 20 cm);
• to reduce the lead angle is recommended to reduce the height of the steps;
• distance between turns of the spiral must be at least 2 diameters structure.

The central axis of a spiral staircase can be formed as a collection column, which stage is suspended and intermediate structural elements.

Calculation of straight stairs on bowstrings

The difference in the structure of Teteven stringers - in mounting the steps to the supporting beam. They are placed in special cutouts (slots) inside. Externally ladder structure looks like a single unit.

Standard dimensions of the string for a span of 90 cm:

• Width - 300 cm (at least 275 cm). Teteven distance above and below the step must be greater than 50 mm;
• thickness - 40 mm (minimum);
• Groove depth - from 20 to 30 mm.

Basic parameters bowstring - distance between the grooves and groove width.

When online calculation steps of the staircase, the top is not necessary to take into account, since it is performed at 2 levels.

It is important to determine how the steps will be attached to the bow. This can be accomplished in an open slot without a base beam or closed manner with the reference line.

You can even set the stage on the supporting or fixing metal corners. However, this method is similar to the calculation of the reference beam.

design calculation is performed according to the general formula given step size srednestaticheskogo human.

It should know! It depends on the depth of the string safe operation ladder.

Program for the calculation of stairs

Special programs for calculating the ladder elements. They can be easily found on the Internet, to understand the calculations can even inexperienced user. They help create a visual model of the future construction.

We can recommend the following programs for the calculation of the stairs:

Software downloaded and installed on your computer easily. Alternatively you can use the online calculator for calculating the stairs on the Internet. For example, at the site www.lesenka.com given parameters with a minimum possible within a short time to receive the calculation of the basic elements.
