About the balcony railing Glass height

Explanation of the provisions of GB 50352-2005 of the General Principles for the Design of Civil Buildings.

The height of the railing in the balcony, verandah and other free places should exceed the height of the center of gravity of the human body, so as to avoid the human body from falling due to the outward shift of the center of gravity when approaching the railing. According to the results of anthropometric measurements in 14 provinces of China in 1980, the average height of men in China is 994mm, and the height of the center of gravity after wearing shoes is 994mm, so it is stipulated in the national standard "fixed industrial protective railing".

The height of the protective railing shall not be less than 1050mm", so this article stipulates that the height of the railing below 24m (equivalent to the height of low-rise and multi-storey buildings) shall not be lower, and the height of the railing shall not be lower than that of more than 24m (equivalent to the height of high-rise and high-rise residential buildings). Note that when the bottom of the railing has a width greater than or equal to, and the height is lower than or equal to the treadable part, according to the normal person stepping on the situation, it is easy for people to step on and stand and look (not climbing), at this time, if the height of the railing is calculated from the floor or roof, then the height of the top surface of the railing will be lower than the height of the center of gravity of the person, which is very unsafe, so it should be calculated from the top surface of the treadable part.

In order to protect the lives of children and teenagers, the railings of their special activity venues should be constructed to prevent climbing, such as small edge bricks that are not suitable for horizontal ornamentation and waterproof materials for parapet walls. When making vertical railings, the clear distance between the rods should not be greater than to prevent the head and body from falling through it. In recent years, in shopping malls and other buildings, the net distance between the vertical rods of some railings is left and right, and children fall accidents from time to time, so children can go to the place of activity, and when the vertical railing is done alone, the net distance between the poles should not be greater.

This article also refers to the ISO DIS 12055 standard "Building construction – Guardrail systems and railings for buildings".

For example, relatively speaking, the guardrails in the hospital are prepared for patients pushing wheelchairs, and the guardrails in schools are prepared for students in school, so the height of the two places is a little different, and the manufacturer should combine the actual reasonable customization.

5 1 5 When the net height of the external window sill from the floor and ground is lower, there should be protective facilities. The clear height of the balcony railing should not be lower than that of residential buildings with six storeys or less, and the clear height of the balcony railing of residential buildings with seven storeys and above should not be lower. Balcony railings should be protected.

The clear distance between the vertical members of the protective railing should not be greater than.

This is in accordance with the requirements of the building code...
