Assembly type installing structure for prefabricated outer wall doors and windows

Abstract

The invention relates to an assembly type installing structure for prefabricated outer wall doors and windows. Groove-and-tongues and glue tanks are sequentially arranged in the periphery of a window frame from inside to outside; a water drip is arranged outside the portion, located at the top of the window frame, of the glue tank; and sloping and flashing are conducted at the portion, located at the bottom of the window frame, of the glue tank. The bottom of the window frame is sealed and fixed through polyurethane foaming agents; and the four edges of the window frame are fixed through sealant. According to the assembly type prefabricated installing structure for the outer wall doors and windows, a concrete interface can be provided between a window and interior through the groove-and-tongues; the sealing materials make no direct contact with the interior, and even though the sealant is damaged, the foaming agents leak, water can be blocked when flowing to the groove-and-tongues; and sloping is conducted at the bottom of the window, the water can be drained to exterior through an action of the gravity.

Description

technical field [0001] The invention relates to a door and window installation structure, in particular to an assembly type prefabricated outer wall door and window installation structure. Background technique [0002] In the cast-in-place structure, the water seepage problems of after-installed doors and windows are endless due to various reasons such as materials and construction, and the construction quality is difficult to control. With the continuous development of prefabricated buildings, doors and windows are directly prefabricated into concrete in the factory, which fundamentally solves the problem of water seepage in doors and windows. However, the problem that arises is that most of the doors and windows on the market cannot last the same life as the building, and it is difficult for owners to replace them later. Contents of the invention [0003] The present invention aims to overcome the defects of the prior art, and provides an assembly-type prefabricated exte...
