Calculation of stair steps tilt design allows convenient and safe design The correct angle of inclination of the staircase steps a positive effect on the convenience of its use. Universal values are not here, because each person has a different step width. Therefore, at the design stage should take into account the interests of those who will most often use the design. When it comes to the public area, in this case the degree of inclination is selected average.
Select stage and angle of stairs to the second floor
As mentioned above, it is necessary to proceed from the needs of those who will most likely be raised or lowered here. Depending on this, to select the optimal slope of stair steps to the second floor. You can build a compact version is suitable even for older people, or give preference Marching variant. classical fans will choose the format of the screw, and supporters of an active lifestyle - razbezhnuyu.
It is necessary to choose the right size of the steps, as well as the angle of inclination of the ladder to the construction harmoniously looked in the room
In order to properly define what should be the angle necessary to analyze the following parameters:
- The height between the first and second floor;
- The maximum and minimum pitch width of households;
- When it comes to the common areas, the comfortable lead angle can be calculated in the average format.
From a practical standpoint, it is recommended for beginners to build on a single indicator - the stride length during a relaxed walk. In order to determine the best rate for private home or office space, the emphasis is on the step size of an adult human. Thereafter, an analysis component sustainer. Here it is necessary to take into account the height and the total number of steps. Greatly simplifies the calculation of the angles a ready project. In this case, only need to take a calculator.
We calculate the angle of the ladder in a private house
To achieve the perfect angle lift will observe the following rules. It is strongly recommended that the height of each stage varied within the range of from 150 to 180 cm will help to make more gradual rise -. 280 to 300 mm - width correctly selected steps.
The more citizens adhere to these indicators, the easier to move up and down. In further interesting values are calculated based on a mathematical formula.
We are talking about the equation: 2x + y = 580: 660 mm. In this formula, x represents the maximum height of the existing steps, and in - their maximum width. It is important to remember that this formula is valid only in respect of the tech designs, where the steps does not exceed 140-145 mm. If it is a custom design, in this case, another formula is used: x + y, where both parameters are as in the formula indicated above.
Recommended parameters are calculated on the basis of their own hands the needs of the owners of premises
After the necessary mathematical research, builders following table listing the allowable angle of ascent was made up:
- When step width 200 and height 200 - convenient angle is 45 degrees;
- 260h170 - 33 degrees;
- 340h130 - 21 degrees;
- 400h100 - 14 degrees.
Builders focus on the fact that these values are relative. Now there are even online calculators for such calculations.
We fix the meter ladder lift within GOST
According to current legislation, the erection of a wooden or metal and wooden ladders is governed by the regulations of the state standard. Those are obligatory, so before you begin, you need to get acquainted with the document.
Do not be amiss to scroll through the SNIP. If the experience in construction and installation works on GOST not, it is best to seek the help of a third party.
Otherwise, even small errors will result in the inability to fix the terms of the stairs.
Do not neglect referral to a specialist in construction and installation works in the construction of stairs, thus you will ensure their safety
Professionals and beginners it is recommended to remember the following regulations of the standard:
- Enabled only span 1 steps, if the structure has only two floors;
- The minimum width of 80 cm (one) and 1 m (for the free passage of two people);
- At each site structure is from 3 to 18 steps.
It is recommended to carry out the calculation in such a way that the number of steps odd happened. The minimum rate, which is defined in the regulatory framework, is 26 degrees, and the maximum - 45.
Set the ladder at an angle
A feature of the external structures of this kind lies in the double fixing. On the one hand, two points ladder bolted to the floor, and three - to the wall. To the operational phase no problems, the design must meet certain requirements. Firstly, the inclination angle varies from 65-75 degrees. In this case, propped up against the structure will be equally useful to all. Secondly, no matter how steep descent turned mentioned staircase modification is not suitable for the transport of heavy loads.
The maximum length of addl wooden ladders should not exceed 5 meters
If it is decided to build it addl format, it is necessary to bear in mind a number of other nuances:
- The design requires annual maintenance;
- Its installation is not suitable for smokers with frequent drops humidity level and temperature;
The presence of 4-lapyh pets - additional risk factor.
The optimum angle of inclination of the ladder: medium static parameter
In cases where each square meter in the literal sense of the weight of the gold or the need to build a ladder in a public place, in this case, the production begins with fixing the basic parameters. Desirably, the sought area ranged from 40 to 44 degrees. If this parameter is due to various reasons can not be achieved, then come to the aid sill.
When selecting the size of the stairs there are no strict rules, because everything depends on the maximum and minimum human stride length
Metal profiles allow for fixation at the required level corner:
- 45 with a width of 200 degrees;
- 29.51 degrees and a width of 280;
- 26.41 degrees with a width of 300;
- 21 degrees and a width of 340;
- 18.3 degrees - width 360;
- 16.21 degrees with a width of 380.
Practical characteristics stairs slope
Measurements need to spend a lot, but all efforts will be compensated. The practical result of the installation correctly adjusted the stairs will be ease of use. In the world there are many examples where sustained load on the lower limbs provoked a variety of pathologies.
In the case of incorrect mathematical research, suffers not only the man but also the staircase.
Non-compliance with the guideline value tilt gradually destroys attachment. The man, who was forced to make a great effort to get up, forced to do more strong steps. The resulting material is subjected to greater physical stress.
Let him on the stairs will be more steps, but they do not provoke an increased load on the lower limbs
the following guidelines will help to avoid such developments:
- If, due to the architectural features of the floor, walls or stairs is impossible to make measurements, then apply temporary rubber clamps.
- At each stage of erection of the lifting structure is used to squares as possible more accurate control of the angle of inclination.
The best option - to make a little smaller than the desired angle.
Features stair step tilt (video)
Comfort Use the stairs at home or in the office depends on the angle and the number of stages. For optimal value definitions used a mathematical formula. The more accurate the calculated score, the better. For substitution in formula takes the maximum height and width of the steps, and the distance from the first step to the second floor.
