What should be the size of ladder steps: 6 options
The optimum size of the steps will make stairs comfortable and bezopasnoySuschestvuyut special rules and standards that govern the optimal size of the steps to the second floor. If you meet the required standards, the ladder will last for many years, while not subjecting their owners to unnecessary risk.
In addition, the ladder must take into account the requirements of the owners.
Select the size of the steps should be taking into account as a personal preference, and all family members
- Suitable clearance;
- Aesthetic appearance;
And plus to this - compliance with GOST and SNIP that ladder would not only please the eye, but also to serve for many years. It is these standards, as well as some other, less important parameters ensure safe movement of the ladder. This is especially true for families where there are children or elderly people. Staircase itself can be of any design and appearance - it depends entirely on personal preference.
But the choice of buyers often stops at the wooden structures: the most durable, resistant and beautiful.
The most comfortable and safe are considered to be the standard level. Their parameters are also regulated by the height of 15-19 cm, and width - 30. In a typical wooden staircase width is equal to 27 cm, but in the corners or on the move on a step creeps so-called overhang (or nose). Its width is just equal to the missing three centimeters.
Size ladder rungs: GOST
In order to not have to wrestle with, what should be the steps and easy descent or ascent did not bring problems, special regulations have been established: they take into account all the necessary standards and detail painted the entire work order. The most important part of the stairs are, of course, the stage.
Before you decide on the size of the steps, it is necessary first to make all necessary measurements
For example, when a drawing is made for future ladder, you must consider the following parameters:
- The angle of inclination of the stairs;
- Their same width;
- The width of the march;
- The depth of the tread;
- The step width.
For the standard of a private house should be a minimum width of 70 cm, without considering guardrails - their width is considered separately. Standard does not recommend the narrow stairs, but allows a similar design - type "goose-step" staircase or attic.
The width of the step is to calculate. Typically, private homes -. Is from 60 to 65 cm taking When calculating formula 2m + B = 60-65, where 2w - two widths, and B - step height.
The optimum size of steps of the staircase in the house
When calculating the size of the steps to the second floor, you need to know some of the nuances.
Make calculations and to choose the correct size of the steps will help Specialist
- Size riser 15-18 cm;
- Tread - 30 cm;
- Comfortable step length from the meter, it is better to 120 cm.
Number of steps themselves are not too difficult to calculate. To do this, you need to know this parameter as the height of the floor. Accuracy must be absolute, otherwise the stage would be different in size. Standards recommend steps to set the height of 15 cm, but it can vary slightly.
Next you need to get the height of the floor in centimeters divided by the height of the steps, and then take one, as the last step will itself.
And you must take into account the gap, that is the height of the stairs to the upper barrier. This is at least two meters - or have to constantly bandage on his head will be bruises. Drawings and calculations is recommended to professionals - without the necessary skills is likely to fatal errors. It is very important to produce lasting and comprehensive training in order to avoid various difficulties.
What is the standard size of the steps of the staircase
Standard dimensions of the steps specified in the GOST and SNIP - to these specifications are obtained almost perfect design.
Size of steps also depends on the total number thereof
The basic standards that must be considered:
- Steps should not differ in size, maximum - 5 mm;
- The height of the stage should not be less than 15 cm, but should not exceed 20 cm;
- From the door to the stairs - not less than one meter, but this distance should exceed the width of the door;
- The dimensions of the eaves - a maximum of 3 cm;
- The depth of the tread of 23 to 35 cm;
- The narrowest part of the winders - 10 cm wide - 40 cm, and the fairway - 25 cm.
Folding ladders are recommended options for at least 600h1000h1200 that it remains secure. If the configuration and availability of space allows, the steps can be made much wider. It is useful to the second floor, you can comfortably bring furniture or other items overall. There is one more advantage - a staircase with wide steps looks impressive, presentable and expensive.
For a spiral staircase parameters do not differ too much. The width of the stairs - not lower than 20 cm next to the central beam -. 10 cm and the widest part - 40.
It should be borne in mind that all steps must be mounted at an angle of 1 degree, which will help to avoid the accumulation of water, dirt and dust on the stairs.
Step ladder steps
This option is almost the most important. From his other calculations are carried out, and it also depends on the comfort and safety of movement on future steps. Miscalculated move may even lead to a deterioration of state of health - from excessive voltage to maintain stability often sore feet, especially in the elderly.
In order to properly do the calculation steps, you need to focus on the specific requirements
The calculation is made according to certain requirements, which ultimately may differ from the SNP. It's not scary, because building codes only summarize information.
- Sum of the tread width and height of the riser should be about 440 mm including the tapering angle of the ladder itself. After all, what it is, the higher the height of the riser.
- By adding a double-size riser and tread width must necessarily exit from 600 to 650 mm.
- It is absolutely safe ladder, for which the difference between the size of the riser and tread of about 46 mm.
- The height and width of the different stages have a maximum of 5 mm.
- The length of the ladder beams affects the slope (it is almost vertical), which in turn can affect the height of the steps.
- The height will affect the amount, as well as on the width.
If something does not fit, it does not work or goes, but not as planned, it does not need to despair. Perhaps it is not a bug - you can change it to solve configuration and ladder type.
The width of the stairs: the norm
So what are the allowable width of the norm? All parameters of the staircase is very dependent on each other. The width depends on the calculations of the resulting height.
Thus it is necessary to rely on some rules:
- Ideal for a wide span of private homes will be 120 cm;
- The width of the same stage - 25 cm;
- If there is a railing - 80 cm;
- In the absence of a railing - 60 cm;
- For propulsion - not less than 60 cm, excluding the construction of the "goose step".
Thinking design ladder, it is also important to take into account the width of the steps that needs to be comfortable for all family members
Of course, in determining the width should be based on your foot - it must completely fit comfortably on the step. Also, the exception to the rule and will be folding stairs - their width may be smaller, but not below the threshold of 20 cm.
It will depend on the width and angle, i.e. the slope of the staircase. For example: the width of 20 cm, the optimum height would be the same and the angle of inclination of - exactly 45 degrees. But if the width of 40 cm, and the height is 10 cm and the angle is 14 degrees and 10 minutes.
Due to the development of technology and the emergence of a variety of other materials of construction for stairs, different standards and requirements has become much more. Match them completely rarely someone comes out - that's why it is recommended to contact the experts or buy ready-made design, rather than trying to erect her own hands - a skill needed here.
There are still a few details that are important to know:
- If the ladder will operate continuously, and it should be fixed.
- Landings shall be equal to the width of the steps.
- It is necessary to pay attention to the SNP, which regulates the height of the railing - from the ceiling to the handrail shall be not less than 190 cm, and preferably 200.
The optimum size of steps of the staircase (video)
The staircase in the house or apartment - a thing necessary and useful. To install an elevator - at least, expensive, and meaningless, for the sake of the two floors. Proper selection and correct drawing circuit ensure that the ladder will last a long time, and also will decorate the home.
