Method for mounting door-window

Abstract

The invention discloses a door and window installing method, comprising the steps of: a) cleaning a hole on a wall and smearing waterproof polymer cement mortar on the surface of the hole; b) using single-side fixing plate to fix a window frame in the hole; c) injecting foam glue into the gap between the window frame and the hole; d) injecting silicone glue into preset soil-built groove around the windowsill outside the window frame. It can avoid forming a water leakage channel; it can strengthen bonding force between hole surface and foam glue, and water-proofing and sealing ability.

Description

technical field [0001] The invention relates to the construction field of building doors and windows installation engineering, in particular to a method for installing doors and windows. Background technique [0002] In the prior art, when doors and windows are installed in the wall openings of the wall, the following measures are generally adopted: [0003] 1. Without any treatment on the surface of the wall hole, water seepage caused by slight cracks and pores in the wall hole cannot be prevented; [0004] 2. In order to fix the window frame conveniently, the two-sided fixing piece is generally used for fixing, that is, a fixing piece is passed through the window frame and nailed on both sides inside and outside, but this will artificially leave a leaking channel, and several pieces are used. The fixed piece is just a few leaking channels, and these channels are difficult to block; [0005] 3. The gap between the window frame and the wall hole is plugged with cement mort...

AI Technical Summary

Problems solved by technology

[0003] 1. Without any treatment on the surface of the wall hole, water seepage caused by slight cracks and pores in the wall hole cannot be prevented;

[0004] 2. In order to fix the window frame conveniently, the two-sided fixing piece is generally used for fixing, that is, a fixing piece is passed through the window frame and nailed on both sides inside and outside, but this will artificially leave a leaking channel, and several pieces are used. The fixed piece is just a few leaking channels, and these channels are difficult to block;

[0005] 3. The gap between the window frame and the wall hole is plugged with cement mortar. After the cement mortar solidifies, a crack will often form between the window frame and the gap, which will cause water leakage;

[0006] 4. After the doors and windows are installed, there is no requirement to reserve a groove on the outside of the window frame when plastering the window sill. Therefore, when the silicone glue is injected at the end, only a thin layer of glue can be applied on the surface of the cement layer, which is easily damaged by the cement mortar layer.
