Question 1: aluminum alloy doors and windows leaking water
Occasionally, aluminum alloy door and window frames are found leaking water at the joints with the wall, especially in the lower corners of the window. Secondly, water seepage occurs at the splicing section of the composite window.
Corresponding measures:
1. Because the coefficient of thermal expansion of the aluminum alloy profile and the wall material is different, under the influence of temperature, the capillary cracks are easily generated at the joint between the frame body and the wall body. In order to prevent water seepage at the cracks, the aluminum alloy door and window frame should be elastically connected to the wall body. Before construction, the floating ash, mortar particles and other debris in the joint groove should be removed first, and then the inside and outside of the frame jointed with the wall body should be marked. The sealant is closed, the glue injection should be continuous, do not omit, and the bond should be firm.
　 2. The exposed connecting screws should also be sealed with a sealant to prevent water leakage.
Question 2: Aluminum alloy doors and windows are not firmly installed, the overall stiffness is poor
The aluminum alloy door and window frame cracks at the junction with the wall; when the door is pushed or opened and closed, the frame fan shakes; when the air pressure is applied or pushed by hand, the window frame is deformed and shaken, giving a sense of insecurity.
Prevention:
1, aluminum alloy doors and windows should be based on the size of doors and windows openings, installation height, choose the right profile.
2. When the door and window frame are installed, the connection piece and the wall should be used for reliable connection. The connecting piece shall be made of thin steel plate with a thickness of not less than 1.5mm and be treated with antiseptic. The connection method generally uses expansion bolts and injection needles embedded in the wall.
3, after the installation of aluminum alloy doors and windows, you can use force to push the door window frame for inspection, if found shaking or deformation, should be reinforced.
