Aluminum alloy doors and windows are the most basic configuration of general residence, and also the most important factor affecting lighting, ventilation and comfort. Do you know about the design standard of aluminum alloy doors and windows?
1、 Sill height
In general residential buildings, the height of windowsill should not be less than 0.9m. When the height of windowsill is lower than 0.8m, protective measures should be taken. In public buildings, the height of windowsill varies from 1.0 to 1.8m, and the bottom height of the window sash opening to the public corridor should not be less than 2.0m.
2、 Window height
In general residential buildings, the height of the window is 1.5m, plus the height of the windowsill is 0.9m, then the top of the window is 2.4m away from the floor. The height of the window should be determined according to the requirements of lighting, ventilation, space image, etc., but attention should be paid to the problem of high rigidity of the window. If necessary, beams or beams should be added 'pied ho '。 In public buildings, the height of the whole glass has exceeded 7.2m, which is beyond the scope of ordinary windows.
3、 Window width
Generally, the window width starts from 0.6m. According to the provisions of building standard opening specifications, the width modulus of general building opening is 300 mm, that is, the general width is 600mm, 900mm, 1200mm, 1500mm, and so on. It should be noted that when the window opening is too wide, the vertical keel or "joint" should be added. Otherwise, the stiffness problem of the window is easy to occur.
