Aluminum alloy doors and windows installation issues
Everyone has a different understanding of home. How can you decorate a perfect home with limited funds? In home renovation, many owners are concerned about the cost of renovation. Therefore, before the renovation, we must plan well. Only good planning can reduce the cost. Here, the living family Xiao Bian specifically for you to integrate the warmer home improvement information this winter, let you dress up a more beautiful love home!
First, engineering design
1. The engineering design must be calculated and tested for strength design. The production, installation, and acceptance are only based on the standard atlas and the type inspection report provided by the profile manufacturer. This is an erroneous and even dangerous behavior. Because the standard atlas is only a partial diagram of a certain series of windows, it does not indicate the load that the construction can bear according to the diagram, so it cannot be used as the basis for production, installation and acceptance. For different series of doors and windows, the strength or deflection check or test must be carried out according to the principle of less stress.
2. The strength and stiffness of landing doors and windows are generally insufficient, and the main force columns (beams) in them should be strengthened.
3. When the height of doors and windows of high-rise buildings exceeds 30M, it shall be carried out in accordance with GB50057 "Lightning Protection Design Code for Buildings".
Second, the choice of materials
1. Aluminum alloy profiles must meet the requirements of GB/T5237-2000 Aluminum Alloy Building Profiles.
2. The selection and configuration of hardware accessories is one of the important factors for ensuring the quality of doors and windows. Even a window with excellent performance must be guaranteed by the selection and configuration of high-quality accessories.
3. The pulleys, tops, anti-shedding sealers, and lower seal blocks for sliding doors and windows are accessories that ensure the quality of sliding doors and windows. Pulleys are the key to the smooth opening and closing of doors and windows. Roller-bearing nylon wheels should be used. The anti-stripping sealer is a safety measure to prevent the window sash from falling off, and at the same time, it has a sealing function between the hook and the upper slide. The ABS plastic and the EPDM rubber with good durability should be used. The lower sealing block plays a sealing role between the hooking rate and the glide path, and can effectively prevent the splashing phenomenon under the effect of the fluctuating load. The EPDM rubber should be used. Tops are the seals of window sashes and window frames, which determine the airtightness of doors and windows. Common chemical fiber slivers will curl and lose their sealing effect. Silicone tops must be used.
4, hinged doors and windows hinges (or sliding window friction hinges), handles, box seals between the sealant is to ensure that the quality of flat doors and windows is an important accessory. The bearing capacity of the hinge (or friction hinge of the sliding window) is the key to the safety of the doors and windows and the smoothness of the opening and closing. The bearing capacity of the hinge is stronger than that of the friction hinge, so the hinge can make a larger window sash For use, friction hinges are only suitable for smaller windows or top-hung windows. Handle important accessories related to safety and sealing performance of doors and windows. The ordinary handle is only applicable to sashes with smaller grids and loads. The European multi-point handle is suitable for sashes with large grids and loads. Use; The sealing strip between the framed fan is the guarantee of the airtightness and watertightness of the flat open door and window, the sealing effectiveness of the original PVC strip is about 5 years, and the regenerated PVC strip does not have the sealing effectiveness. It is desirable to use a weather resistant rubber such as EPDM.
5. The model, specification and performance of hardware accessories shall comply with the relevant provisions of the current national standards.
6. Structural adhesives and weather-resistant adhesives used for concealed frame windows should be tested for compatibility with profiles and glass prior to use.
