What Should I Do If the Aluminum Alloy Doors and Windows Are Not Firm When They Are Not Firmly Leak? -WJW Aluminum Supplier Aluminum

The aluminum alloy doors and windows frame cracks with the seams of the wall; push or open and close the doors and windows, and the frame and fan shake; under the wind pressure or manual push, the window frame is deformed and vibrated, giving people a sense of insecurity, giving people a sense of insecurity. The cause of these quality problems is: 1. Improper selection of doors and windows, small specifications, and thin profile thickness. 2. The connection and fixed method of the doors and window frames and the wall. 3. When the combination of doors and windows stitching, the structure is unreasonable, the connection is not firm, and the deformation occurs after the force. In order to solve these problems, the following preventive measures should be taken: 1. Select aluminum alloy doors and windows according to the size and installation height of the doors and windows. Residential engineering aluminum alloy profile section, flat window forms are not less than 55 series; sliding windows are not less than 75 series; inner balcony tablet windows are not less than 75 series. The wall thickness of the aluminum alloy door is not less than 1.4mm, and the wall thickness of the aluminum alloy window type is not less than 2mm. 2. When installing the doors and windows, the connector should be used to connect with the wall. The distance between the connector and the frame angle should not be greater than 180mm, and the distance between the connector should not be greater than 500mm. The connection parts should be made from a thin steel plate of not less than 1. The thickness of 5mm, should be carried on anti -corrosion treatment. The connection method generally uses an expansion bolt or an open iron foot embedded on the wall. 3. When installing and combined doors and windows, pay attention to the reasonable setting of the middle and middle gears to ensure the overall stiffness of the connector and doors and windows. The specifications of the connector meet the requirements. In daily use, sometimes it is found that leakage occurs at the connection between the aluminum alloy doors and windows, especially in the lower corner of the window, and then leak at the joints of the composite window. The reasons for leakage are as follows: 1. Cracks appear at the connection between the doors and windows frames and the wall. The sealing materials are not encrypted during installation. 2. When the doors and windows are stitched together, there is no sleeve, overlap joint, and no sealing rubber seal. In order to prevent the doors and windows from leaking, corresponding measures should be taken during construction: 1. Because the thermal expansion coefficient of aluminum alloy profile is different from the thermal expansion coefficient of the wall material, under the temperature effect, the coat cracks are prone to the connection between the frame body and the wall. In order to prevent crack seepage, the framework of the aluminum alloy doors and windows should be flexibly connected to the wall. The outer side of the frame should be embedded in the wooden bar, set the seam of 5mm 8mm. During the construction process, it should be removed from the seam slot, and the sundries such as floating ash, mortar particles, etc., and then inject sealing around the wall seams inside and outside the frame. 2. When installing the door and window component for stitching, it should be inserted or overlap. It is strictly forbidden to adopt a combination of plane and plane. At the same time, the exposed connection screws should also be sealed to prevent water seepage. After installing aluminum alloy doors and windows, you can press the door and window framework to check. If you find that the door and window frame is vibrated or deformed greater than L200, it should be reinforced.
