Method for preventing side expansion of window frame gap filling foaming agent

Abstract

The invention discloses a method for preventing side expansion of a window frame gap filling foaming agent. The method comprises the following steps that an anti-expansion rubber strip is manufactured according to the width of a gap between a window frame and a wall body and the fixed required thickness, and the length of the anti-expansion rubber strip is enabled to be consistent with the width and height side length of a window opening; the anti-expansion rubber strip is installed in a gap between the window frame on the upstream face of the window frame and the wall body and fixed between the window frame and the wall body through a nail gun or glue; after the fixing glue of the anti-expansion rubber strip is solidified, the downstream face of the window frame is filled with a foaming agent, and the foaming agent is prevented from overflowing out of the gap between the window frame and the wall body; and after the gap filling foaming agent is solidified and stabilized, the redundant foaming agent is leveled on the downstream face of the window frame through a cutter, window frame edge plastering can be conducted, and window frame installation is completed. The method overcomes the defects of traditional foaming agent joint filling, construction is convenient, through joints generated by foaming agent cutting are avoided, window frame leakage is reduced or eradicated, and the installation quality of the window frame is improved.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a method for preventing the lateral expansion of a window frame joint foaming agent. Background technique [0002] When the window frame is installed, it is usually required that the window frame is in soft contact with the wall. In order to meet this demand, at present most of the gaps between the window frame and the wall are injected with foaming agent. However, due to its own characteristics, the foaming agent will expand to both sides of the window frame, and it is necessary to put The foaming agent that expands to the outside of the window frame is cut flat. After cutting, the foaming agent is likely to produce joints, which may cause leakage at the window edge, which seriously affects the installation quality of the window frame. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for preventing...

In order to meet this demand, at present, most of them use foaming agent to fill the gap between the window frame and the wall. However, due to its own characteristics, the foaming agent will expand to both sides of the window frame. When plastering the window frame, it is necessary to The foaming agent that expands to the outside of the window frame is cut flat. After cutting, the foaming agent is easy to produce cracks, which may cause leakage at the window edge, which seriously affects the installation quality of the window frame.
