A method of sealing the gap between the window frame and the wall by pressure grouting

Abstract

The invention relates to a method of blocking a gap between a window auxiliary frame and a wall through pressure grouting. The method includes the following steps that multiple seal strips are uniformly and fixedly installed at the two sides of the window auxiliary frame, and it is ensured that the seal strips and the wall as well as the auxiliary frame and the seal strips are connected tightly; agrouting opening is reserved in the middle of the lower side of the window auxiliary frame, two overflow holes are formed in the top of the window auxiliary frame, and the grouting opening and the overflow holes are formed in one indoor side; before grouting, a grouting connector is installed on the grouting opening and is directly inserted to the window auxiliary frame, the lower end abuts against a brickwork and makes close contact with the brickwork, then a grouting pipe is connected, an air compressor is started for grouting; after grouting is completed, the grouting connector is pulled out, a non-return inserting sheet is inserted, and then the grouting connector is installed to a next window to conduct grouting on the next window. By means of the method, the gap between the window auxiliary frame and the wall can be filled densely, the method improves filling quality and the waterproof effect, operation is easy, and construction is convenient and fast.

Description

Technical field: [0001] The invention belongs to the field of engineering construction, in particular to a method for sealing the gap between a window frame and a wall by pressure grouting. Background technique: [0002] Due to frequent heavy storms and rains in typhoon-prone areas, waterproofing of exterior walls during construction is the focus of project implementation. The most common location for external wall leakage is at the window. If the gap between the window frame and the wall is not properly sealed, it will easily lead to water leakage from the window. [0003] According to the current construction specifications, there is generally a 15mm-25cm gap between the window frame and the wall, which should be sealed tightly with waterproof mortar to ensure that the outer wall does not leak. Our conventional construction method is: one-sided sealing, and then filling with waterproof mortar, that is, first plastering one side of the attached frame, filling with waterpro...

AI Technical Summary

Problems solved by technology

[0005] 1. When plastering one side first, ordinary mortar can easily enter the gap to be filled with waterproof mortar

[0006] 2. Since one side has been plastered and blocked, it is difficult to clean up the garbage in the gap

[0007] 3. The most important thing is that no matter how it is filled, it is difficult to fill the closed chamber with mortar, especially on both sides and top of the window. cause windows to leak
