A Construction Method for Closing Holes Through Walls by Using Wall-Through Sleeves

Abstract

A novel wall-piercing sleeve and a construction method for wall-penetrating hole sealing using the same, wherein the sleeve of the novel wall-piercing sleeve is provided with a stress metal reel, the central axis of which is parallel to the central axis of the sleeve, and the stress metal reel The barrel can be self-adaptive according to the diameter of the equipment pipe, and its outermost end is welded on the inner wall of the sleeve for fixing; in the construction of sealing the hole through the wall, first insert the sleeve into the matching elastic rubber sealing tube , when crossing the wall horizontally, both ends of the spacer can be elongated and kept moving horizontally as a whole, when the sleeve is in the middle of the wall, the elongated spacer can be retracted naturally, and the sleeve is tightly bound to the wall; put the device The pipe passes through the center of the stress metal reel, so that the stress metal reel tightly wraps the equipment pipe, and finally, foam glue is filled between the sleeve and the stress metal reel. On the construction site, the wall bushing can be accurately measured and cut according to the wall thickness, and the elastic rubber sealing tube is used in conjunction with it. The operation is simple and easy, and it can be adapted to various reserved holes and rear openings.

Description

technical field [0001] The invention relates to the technical field of plugging holes through walls, in particular to a construction method for plugging holes through walls by using wall-penetrating sleeves. Background technique [0002] In architectural decoration projects, it is common to "pierce holes" in the walls above the ceiling. Due to the lack of simple and economical wall bushings and wall hole plugging structures, at present, the professional installation of mechanical and electrical equipment is often the first construction, and then handed over to the wall. Subsequent plugging is carried out by the general contracting department of the project. Due to the different sizes of the openings, the plugging process used by the workers is also different. Generally, it is a wet method for plugging, the process is cumbersome and complicated, and the price is relatively expensive. Problems such as leakage plugging and high construction cost occur, which affect the project ...

Problems solved by technology

[0002] In architectural decoration projects, it is common to see "holes" in the walls above the suspended ceiling. Due to the lack of simple, economical and applicable wall-through casings and wall-through hole sealing structures, at present, electromechanical equipment installation is often carried out first, and then handed over Subsequent sealing is carried out by the general contracting department of the project. Due to the different sizes of the holes, the workers use different sealing techniques. Generally, the sealing is done by wet method, and the process is cumbersome and complicated. At the same time, it is expensive and easy There are problems such as leaking and high cost, which will virtually affect the progress of the project and the construction cost. Therefore, it is urgent to develop a new type of wall bushing
