Stairs are used for traffic connections between floors, but modern staircases are not just for practical use, modern staircases are also more ornamental, safe and comfortable. So how much do you know about the stairs? What is the height of the standard stair railing?
First, indoor stair railing height specification
The height of the interior staircase decoration is 90cm. Of course, this data can be changed according to the actual situation. When the length of the stairs exceeds 5 meters, the height of the stair rails can be appropriately raised to 100 cm. In addition, if there are children in the family, for safety reasons, it is better to set the height of the stair railings to 100cm.
Second, the outdoor stair handrail specification
When the altitude is below 24 meters, the height of the outdoor shared stair handrail should not be lower than 105cm. When the height of the air is above 24 meters, the height of the outdoor stair handrail should not be lower than 110cm. .
Third, other stair railing installation precautions
1. The algorithm of the stair handrail height: the vertical height from the stair step or roof to the top of the stair handrail is the calculation method of the stair handrail height.
2. The clearance between the vertical bars of the railing should not exceed 11cm, especially for children in the family.
3, the railing should not be left empty from the floor or roof height of 10cm.
In order to establish a stair handrail height standard, the mandatory provisions in the General Rules for Civil Building Design JGJ37-87 also have the following provisions:
1. The railing shall be made of strong and durable materials and shall withstand the horizontal loads specified in the load code;
Second, the height of the railing should not be less than 1.05m, and the height of the railing of the high-rise building should be increased appropriately, but it should not exceed 1.20m;
3. The railing should not be left empty at a height of 0.10m from the ground or roof;
4. Where there are children's activities, the railings should adopt structures that are not easy to climb.
The above is about the standard stair railing height, I believe you have a new understanding of the stairs.
