Code for Residential Design (GB 50096- 1999)2003? Description of terms

1,? Balcony is a place where children have more activities. If the vertical bar spacing of railings (including local railings on the fence board) is not properly designed, it will easily lead to accidents. According to the principle of ergonomics, the vertical clear distance of railings should be less than 0. 1 1m to prevent children from getting off. At the same time, in order to prevent people from falling because of placing flowerpots on the railings, this article requires that the railings where flowerpots can be placed must take measures to prevent falling.

2, according to the human center of gravity and psychological requirements. Balcony railings should increase with the height of the building. Closing the balcony did not change the stability and psychological requirements of the human center of gravity. Therefore, the enclosed balcony railing should also meet the clear height requirements of the balcony railing. Solid railings are required for middle-high-rise buildings and residential balconies in cold and severe cold areas, one is to prevent cold air from pouring into the room from the balcony door, and the other is to prevent articles from falling from the gaps in the railings and hurting people. In addition, it is common for middle and high-rise buildings, high-rise houses and houses in cold and severe cold areas to close balconies, so it is difficult to close empty railings.

3. There is no balcony or platform adjacent to the windowsill. If the clear height from the ground is low, it is easy for children to fall. This article requires that protective measures should be taken when the windowsill is less than 0.90 meters from the ground. The effective protective height should ensure a clear height of 0.90 meters, and the treadable surfaces such as countertops and transverse railings which are less than 0.45 meters away from the floor (ground) surface and are easy to cause unconscious climbing should not be included in the clear height of the window sill.
