Those who do doors and windows must know these data!
As a component of the building envelope, doors and windows are given different architectural functions and requirements, whether it is a high-end building or an ordinary residence, such as meeting the architectural effects, rain protection, lighting, ventilation, vision, thermal insulation, and insulation. Sound and other functions can provide people with a comfortable and quiet indoor environment and achieve the requirements of sustainable social development.
The height of the door for people to pass is generally between 2m and 2.4m, otherwise it will feel hollow, and the door leaf production needs to be strengthened. However, when modeling, ventilation, and lighting are needed, a waist window can be added to the door. The height of the window should be 0.4m and should not be too high.
The door for vehicles or equipment to pass through 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 to prevent the vehicle from hitting the door frame due to bumps or when the equipment needs to be moved with rollers. As for the clearance requirements for various types of vehicles, please refer to the corresponding relevant regulations.
For large-volume and large-space buildings such as stadiums, exhibition halls, etc., 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 buildings. They are not often passed through. Therefore, the height of the upper frame is generally equal to or lower than that of ordinary doors, and there is still a threshold with the same height as the skirting line below, and its clear height There is no need to stick to 2m, just about 1.5m. In hotel rooms, the net height of the door opening is ≥2.1m.
In general, the household door is 0.9~1m, the door of the room is 0.8~0.9m, the kitchen door is about 0.8m, and the bathroom door is about 0.7~0.8m. Due to the import of modern furniture, the upper limit size is now used.
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 width of the door leaf for double or multiple doors should be 0.6～1.0m. The width of the door opening of the hotel room is generally ≥0.9m, and the width of the bathroom door ≥0.75m.
The width of fire exits for safe evacuation shall be set according to calculations and regulations (related fire protection regulations). The width of the door for maintenance of the pipeline well is generally 0.6m. In addition to its own width, the door for vehicles or equipment to pass only has a gap of 0.3-0.5m on each side.
In general residential buildings, the height of the window sill is required to be no less than 0.9m. When the height of the window sill is lower than 0.8m, protective measures should be taken. In public buildings, the height of the window sill varies from 1.0 to 1.8m, and the height of the bottom of the window sash that opens to the public walkway should not be less than 2.0m.
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 the window should be determined according to the requirements of lighting, ventilation, space image, etc., but attention should be paid to the rigidity of the window if it is too high, and beams or "pins" should be added when necessary. In public buildings, the height of the whole piece of glass has exceeded 7.2m, which is no longer the scope of ordinary windows.
The window width generally starts from 0.6m. According to the regulations in 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, and so on. It should be noted that when the window opening is too wide, a vertical keel or "pitch" should be added, otherwise the width of the window is prone to problems.
