Novel wall bushing and through-wall hole blocking method adopting same

Abstract

The invention discloses a novel wall bushing and a through-wall hole blocking method adopting the same. A stress metal reel is sleeved with a sleeve of the novel wall bushing, the axis of the stress metal reel is parallel to the central axis of the sleeve, the stress metal reel is adaptive to different diameters of equipment pipes, and the outmost end edge of the stress metal reel is welded to the inner wall of the sleeve to be fixed. During through-wall hole blocking, the sleeve is inserted into an elastic rubber sealed tube matched with the sleeve firstly, the two ends of a gasket can be lengthened and integral transverse movement is maintained when the elastic rubber sealed tube penetrates through a wall transversely, the lengthened gasket is retracted naturally when the sleeve is located in the middle of the wall, and then the sleeve and the wall are closely fastened; an equipment pipe is made to pass through the center of the stress metal reel to be tightly wrapped with the stress metal reel, and finally the space between the sleeve and the stress metal reel is filled with filling foam glue. On a construction site, the wall bushing can be precisely measured and cut according to wall thickness. Through the cooperation of the wall bushing and the elastic rubber sealed tube, operation is easy, and the novel wall bushing is adaptable to various pre-formed holes and after-formed holes.

Description

technical field [0001] The invention relates to the technical field of plugging through-wall holes, in particular to a novel wall-through casing and a construction method for plugging through-wall holes using the same. Background technique [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 proje...

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
