Design standards for aluminum alloy doors and windows.




With the increasing improvement of aluminum alloy doors and windows production technology, a good aluminum alloy door and window design can well solve factors such as lighting, ventilation, and comfort. With regard to the design standards of aluminum alloy doors and windows, there are mainly these five aspects.

First, the height of the window sill of aluminum alloy doors and windows.
  
For general residential buildings, the height of the window sill should not be less than 0.9m. Once the height of the window sill is lower than 0.8m, protective measures should be taken. If it is a public building, the height of the window sill can vary from 1.0 to 1.8m. For window sashes that open to the public walkway, the height of the bottom surface should not be less than 2.0m.

Second, the window height of aluminum alloy doors and windows.
  
In general residential buildings, the height of the window is 1.5m, plus the height of the window sill is 0.9m, and the window top is 2.4m away from the floor. The height of aluminum alloy doors and windows should be determined according to the requirements of lighting, ventilation, and space image. If the window is too high, you need to add beams or "fighting" to protect it. In public buildings, if the height of the whole piece of glass exceeds 7.2m, it will not belong to the scope of general windows and needs to be paid attention to.
  
Third, the window width of aluminum alloy doors and windows.

The window width of aluminum alloy doors and windows generally starts from 0.6m. According to the provisions of the building standard opening specification, the width modulus of the general building opening is 300mm, that is, the general width is 600mm, 900mm, 1200mm, 1500mm, etc. and so on. Once the window opening is too wide, a vertical keel or "fighting" should be added. Otherwise, the rigidity of the window will be difficult to withstand the pressure and cause problems.
  
Fourth, the height of the doors of aluminum alloy doors and windows.
  
The height of the door for people to pass is generally not less than 2m, no matter how high it is, it should not exceed 2.4m, otherwise it will feel hollow, and the door leaf production needs to be strengthened. If there is a need for modeling, ventilation, lighting, etc., a waist window can be added to the door, the height of which starts from 0.4m. For safety reasons, the height should not be too high. For the door for vehicles or equipment to pass through, it should be determined according to the specific situation, and its height should be 0.3-0.5m higher than that of the vehicle or equipment, so as to prevent the vehicle from hitting the door frame due to bumps or when the equipment needs to be transported by rollers. As for the clearance requirements for all types of vehicles, it is necessary to consult the corresponding regulations. For large-volume and large-space buildings such as stadiums and exhibition halls, when super-scale doors need to be installed, a regular-size attached door can be added to the door leaf for people to pass through when the door does not need to be opened.

Nowadays, there are many inspection doors for various equipment tube wells in the building, but because they are not often put into use, the height of the upper frame is generally equal to or lower than that of ordinary doors, and there are still thresholds at the same height as the skirting line. The net height does not need to be restricted to 2m, just about 1.5m. Hotel rooms, the net height of the door opening ≥ 2.1m.

Fifth, the width of the door of aluminum alloy doors and windows.
 
Generally, the household door is 0.9~1m, the door of the room is 0.8~0.9m, the door of the kitchen is about 0.8m, and the door of the bathroom is about 0.7~0.8m. Due to the consideration of the moving in of modern furniture, the upper limit size is now more adopted. The width of the door of public buildings is generally 1m for a single door and 1.2~1.8m for a double door. The width of the door leaf should be considered when it is wider. The door leaf width of a double door or multiple doors is preferably 0.6~1.0m. The width of the hotel room door opening is generally ≥0.9m, and the width of the bathroom door opening ≥0.75m. The width of the fire exit for safe evacuation shall be set in accordance with calculations and regulations (related fire protection regulations). The width of the door for the overhaul of the pipeline well is generally 0.6m. For the doors for motor vehicles or equipment to pass through, in addition to its own width, only a gap of 0.3-0.5m is left on each side to avoid friction accidents such as motor vehicles.
