Doors and windows are the most basic configuration of general housing, and they are also the most important factors affecting lighting, ventilation and comfort. The window sill height in general residential buildings, the requirements of the window sill height is not less than 0.9m, when the window sill height is less 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 surface of the window sash opening 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, the top of the window is 2.4m from the floor surface. The height of the window should be determined according to the requirements of lighting, ventilation, space image, etc., but pay attention to the excessive rigidity of the window, and if necessary, add a beam or "frame". In public buildings, the height of the whole piece of glass has exceeded 7.2m, which is no longer within the scope of general windows. Window width window width generally starts from 0.6m, according to the provisions of the building standard hole specification, the width modulus of the general building hole is 300mm, that is, the general width is 600mm, 900mm, 1200mm, 1500mm, and so on. It should be noted that when the window is too wide, a vertical keel or "splicing" should be added, otherwise the stiffness of the window is prone to problems. The height of the door for people to pass through the door, the height is generally not less than 2m, no matter how high it is, it should not exceed 2.4m, otherwise there will be a sense of emptiness, and the door leaf production needs to be specially strengthened. Such as modeling, ventilation, lighting needs, can be added on the door waist window, its height from 0.4m, but not too high. The door for vehicles or equipment to pass through shall be determined according to the specific situation, and its height should be 0.3~0.5m higher than that of vehicles or equipment, so as to avoid collision with the door frame when vehicles are bumped or equipment needs to be carried by rollers. As for the clearance requirements for all types of vehicles, consult the corresponding specifications. If it is a large-volume and large-space building such as a stadium or an exhibition hall, when a super-scale door is needed, an additional door of conventional size can be added to the gate fan so that people can pass through when the door does not need to be opened. At present, there are many inspection doors for various equipment tube wells in the building, which are not places that often pass through, so the upper frame is generally the same as or lower than the ordinary door, and there is a threshold at the same height as the skirting line at the bottom, so its net height does not need to be rigidly limited to 2m and 1.5m. Hotel room, clear height of door opening ≥ 2.1m. The width of the door is generally 0.9~1m for residential separate doors, 0.8~0.9m for separate rooms, 0.8m for kitchen doors and 0.7~0.8m for toilet doors. due to the moving in of modern furniture, the upper limit size is now adopted. The door width of public buildings is generally 1m for a single door and 1.2~1.8m for a double door. If the door width is further wider, the production of the door leaf should be considered. The width of the door leaf for a double door or multiple doors should be 0.6~1.0m. The width of the hotel room door opening is generally ≥ 0.9m, and the width of the bathroom door opening is ≥ 0.75m. The width of the exit door for safe evacuation shall be set according to the calculation and specifications (relevant fire protection specifications). The width of the maintenance door of the pipeline well is generally 0.6m. For motor vehicles or equipment through the door, in addition to its own width, each side is only set aside 0.3~0.5m gap. Doors and windows maintenance should regularly clean the dust on the doors and windows, keep the doors and windows and glass, hardware clean and bright. If the doors and windows are contaminated with oil stains and other things that are difficult to clean, it is best not to use strong acid or alkali solution for cleaning, otherwise it is not only easy to damage the surface finish of the profile, but also damage the protective film and oxide layer on the surface of the hardware and cause corrosion of the hardware. When opening doors and windows, the intensity should be moderate, try to keep the opening and closing speed uniform. Try to avoid hitting doors and windows with hard objects or scratching the surface of the profile. The granular and other sundries on the inner side of the frame should be cleaned in time to avoid blocking the drainage channel and causing poor drainage and water leakage. When it is found that the doors and windows are not flexible to open or other abnormal conditions during use, the cause should be found in time. If the customer cannot eliminate the fault, contact the door and window manufacturer and supplier so that the fault can be eliminated in time.
