ã€China Aluminum Industry Network】 1. It is necessary to do strength planning calculations and experiments for the project planning. The manufacturing, installation and inspection are carried out only according to the specification atlas and the type inspection statement provided by the profile manufacturer. This is an act of fault or even risk. Because the specification atlas is only a large-scale diagram of a certain series of windows, it does not indicate the loads that can be accepted according to the construction of the diagram, so it cannot be used as a basis for manufacturing, installation, and inspection. For different series of aluminum alloy doors and windows, it is necessary to check the strength and deflection of the aluminum alloy doors and windows according to the stress conditions and experiments. 2. The strength and rigidity of floor-standing aluminum alloy doors and windows are in short supply. The main column (beam) between them should be strengthened. 3. If the azimuth height of the outer aluminum doors and windows of the high-rise building is greater than 30M, it shall be performed in accordance with GB511057 “Code for the Construction of Lightning Protection Plans for Buildingsâ€. Data selection 1. It is necessary for aluminum alloy profiles to meet the requirements of GB/T 5237-2400 "Aluminum Profile Construction". 2, hardware accessories selection and equipment is to ensure the quality of aluminum alloy doors and windows one of the important factors. Even if it is a functional window, it must be ensured by the selection and equipment of high-quality accessories. 3, push-pull aluminum alloy doors and windows of the pulley, tops, anti-drop sealer, lower seal block is to ensure the quality of push-pull aluminum alloy doors and windows are more important accessories. The pulley is the key to the smooth opening and closing of aluminum alloy doors and windows. The roll nylon wheel should be used. The anti-drop sealer is a safety device that prevents the window sash from falling. It is ensured that the seal function between the hook and the upper slide is combined together. The ABS plastic and the EPDM rubber having a good durability ratio should be used. The lower sealing block serves as a sealing effect between the hooking rate and the glide path, and can effectively prevent the appearance of splashing under the effect of the fluctuating load. The EPDM rubber should be used. The top is the seal of the window sash and the window frame. It determines the airtightness of the aluminum alloy doors and windows. Generally, the chemical fiber sliver will bend and lose the sealing effect. It is necessary to use siliconized wool tops. 4. The hinges of aluminum alloy doors and windows (or sliding hinges, conflict hinges), handles, and the sealing strips between the framed fans are the accessories that ensure the quality of flat open aluminum alloy doors and windows. The bearing capacity of the hinge (or the sliding hinge of the sliding window) is the key to the safety and opening and closing of the aluminum alloy doors and windows. The bearing capacity of the hinge is stronger than that of the conflict hinge, so the hinge can be used to manufacture the sub-cells. With large sashes, conflict hinges are only suitable for smaller windows or top hung windows. Handle the important accessories related to the safety and sealing function of aluminum alloy doors and windows. The general handle is only applicable to the sashes with smaller grids and loads. The European multi-point handles are suitable for large grids and loads. Window sashes are used; the sealing strips between the framed fans are to ensure the airtightness and watertightness of the flat-opening aluminum alloy doors and windows, and the sealing of the native PVC strips is useful for about 5 years. The reclaimed PVC strips do not have the usefulness of sealing. The ambition is to use EPDM and other weather-resistant rubbers. 5. The model, standard and function of hardware accessories should be in accordance with the relevant provisions of the current national regulations.
