manufacturers tell you: Aluminum-plastic doors and windows are widely used in current residences. In the actual installation and construction, if you do not pay attention to some details, it will often leave hidden dangers for future use. Now ask an expert to teach you how to shut down the installation. Problem 1: Water leakage of aluminum alloy doors and windows. Aluminum-plastic doors and windows are widely used in current residences. In the actual installation and construction, if you do not pay attention to some details, it will often leave hidden dangers for future use. Now ask an expert to teach you how to shut down the installation. Problem 1: Water leakage of aluminum alloy doors and windows In daily use, water leakage is sometimes found at the junction of the aluminum alloy door and window frame and the wall, especially in the lower corner of the window; secondly, water seepage occurs at the joint of the combined window. Corresponding measures: 1. Because the thermal expansion coefficients of aluminum alloy profiles and wall materials are different, under the influence of temperature, capillary cracks are likely to occur at the junction of the frame and the wall. In order to prevent water seepage at the cracks, the aluminum alloy door and window frame should be elastically connected to the wall. During construction, the floating ash, mortar particles and other debris in the groove of the connection should be removed first, and then injecting around the connection between the frame and the wall The sealant should be sealed, the glue injection should be continuous, don't miss, and the bond should be firm. 2. The exposed connecting screws should also be buried and sealed with sealant to prevent water seepage. Problem 2: The installation of aluminum alloy doors and windows is not firm, and the overall rigidity is poor. The aluminum alloy door and window frames are cracked at the connection with the wall; when sliding or opening and closing doors and windows, the frame fan shakes; , Giving people a sense of insecurity. Prevention measures: 1. Aluminum alloy doors and windows should be selected according to the size of the door and window opening and the installation height. 2. When installing the door and window frames, the connecting piece should be used to make a reliable connection with the wall. The connecting parts should be made of thin steel plates with a thickness of not less than 1.5mm and have anti-corrosion treatment. The connection method generally uses expansion bolts and injection needles to be embedded in the wall. 3. After the aluminum alloy doors and windows are installed, the door and window frames can be pressed hard for inspection. If shaking or deformation is found, it should be reinforced.
