When families replace system doors and windows, they are not familiar with the removal and installation of doors and windows. Therefore, for families who need to install, how to check the installation quality of doors and windows has become a matter of learning and understanding. In the installation of system doors and windows, the vertical frame is the most critical part, which directly determines whether the windows are beautiful and practical. According to the door frame position line measured at the opening of the system door and window to be installed, the center line of the door and window frame must be placed on the inner side of the position line or the position line. There are two installation methods for installing system doors and windows: dry installation and wet installation. Due to the different installation methods, the way the door and window frames are firmly fixed on the opening wall is also different. Dry installation When dry installation is used, the installation of the metal accessory frame should be completed before the opening and wall plastering, and the system doors and windows should be installed after the plastering. The dry installation requirements of the door and window metal accessory frame are as follows: (1) The effective width of the side of the metal accessory frame used to connect the door and window frame of the system shall not be less than 30 mm. (2) The metal fixed frame is connected and fixed to the wall of the opening through a fixing piece. The fixing parts are installed on both indoor and outdoor sides of the metal fixing frame to connect with the wall. (3) The distance between the fixed parts of the metal frame and the corners should not be greater than 150mm, and the distance between two adjacent fixed parts should not be greater than 500mm. Wet installation When using wet installation, install the system door and window frame before plastering the opening and the wall and the system door, window and window frame and the wall. The fixing of the opening of the system door and window frame is performed by the fixing plate. The requirements for the fixed plate are the same as for dry installation. The distance between the fixed parts of the system door and window frame and the wall should not exceed 150mm from the corner, and the distance between the centers of two adjacent fixed parts should not exceed 500mm. The connection between the fixed parts and the system doors and windows should adopt the card slot connection method. When connecting the slot
aluminum alloy door and window frame, self-tapping screws or blind rivets can be used. After installing the system door and window frame, the area around the window frame that contacts the plastering layer of the opening should be treated with anti-corrosion treatment. It can be protected by spraying anti-corrosion materials or pasting plastic film.
