After-assembly method of aluminum alloy door and window

Abstract

The invention discloses a rear installation method for an aluminum alloy door or window. The rear installation method comprises the steps: the reserved holes together with the wall body of a door or window are whitewashed, and a mark is made at the concrete block on a fixed door or window frame; the aluminum alloy door or window frame is positioned in a door or window frame hole; a fixing metal part is glidingly clipped with the aluminum alloy door or window frame and is moved to the concrete block, a process hole is perforated on the corresponding position of the aluminum alloy door or window frame, the fixing metal part and the concrete block are fixed through the process hole by utilizing a nylon expansion pipe, and the process hole is plugged through a process cover; a foaming agent is applied through a needle by utilizing the injection method, so as to ensure the foaming agent in the concave cavity of the aluminum alloy frame to be compact and even, and then a sealant is applied on the edge of the external frame of the door or window; and the door or window is installed. By adopting the rear installation method, the rainwater leakage phenomenon is eliminated.

[0002] The leakage of aluminum alloy doors and windows has always been a common problem in the door and window industry. The conventional installation method of aluminum alloy doors and windows is to install the door and window frames in the reserved door and window openings after the concrete or blocks are completed, and then do other work such as whitewashing around them. , but there are often many contradictions in the installation process of aluminum alloy doors and windows and the cooperation of civil construction, and the final result is that the density around the door and window frames cannot meet the requirements, resulting in leakage, and pollution during the whitewashing process after the door and window frames are installed The window frame must be cleaned before the glass is installed, which consumes a lot of labor. At the same time, the whitewashing of the door and window frame edge structure cannot be done together with the original structural surface, resulting in unsightly whitewashing, poor workmanship, and waste of materials.
