Process for filling clearances of general auxiliary frames or general frames of construction windows and doors through one-time pressure injection

Abstract

The invention discloses a process for filling clearances of general auxiliary frames or general frames of construction windows and doors through one-time pressure injection, which comprises the following technological steps: firstly, arranging fabricated formworks on the lateral surfaces of the auxiliary frames or frames of the windows and doors and an opening wall; secondly, beginning to inject filling materials in clearances between the auxiliary frames or frames of the windows and doors and an opening through mechanical pressure, and completing posttreatment on clearance openings; and removing the fabricated formworks after the filling materials are cured or semi-cured. The construction method can improve the compactness of clearance filling, prevents the occurrence of poor compactness of manual clearance filling, improves heat insulation and construction quality, also improves work efficiency, simultaneously ensures the quality and safety of connection between the auxiliary frames or frames of the windows and doors and the wall, and solves the problems of water seepage, water leakage and the like caused by the poor compactness of the clearance filling of the auxiliary frames or frames of the windows and doors.

Description

technical field [0001] The invention relates to a construction method, in particular to a construction process for gap filling between a frame or frame of a building door and window and a reserved opening. Background technique [0002] At present, there is a specified gap between the frame or frame of the door and window and the reserved opening, which is convenient for the installation of the frame or frame of the door and window. For the above gap, after the frame or frame of the door and window is installed and fixed, it is manually filled and The method of batch blocking is used to complete the post-filling and surface treatment work. For larger gaps, construction personnel generally use the method of filling broken bricks and other impurities in the inside, and then manually filling and batching the surface. The method has the phenomenon of slow construction progress, poor gap filling density and poor reliability. , and there are impurities such as broken bricks inside...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a construction method for one-time pressure injection caulking with a universal frame or frame for building doors and windows. The formwork and mechanized pressure injection are used in the caulking, especially for the door and window frames with relatively small width, which not only improves work efficiency, Moreover, it also improves the compactness of gap filling, improves the construction quality, and solves the problem of low construction quality in the existing door and window caulking technology
