Blocking method of outer wall hole and blocking filling hopper

Abstract

The invention provides a blocking method of an outer wall hole and meanwhile further provides a blocking filling hopper of the outer wall hole. The inner wall of the hole is roughened and cleaned completely, then the filling hopper is arranged on the inner side of the outer wall hole, a blocking piece is arranged on the outer side of the outer wall hole and connected and fixed through a three-section type water stop split bolt, and then concrete is poured from the filling hopper. The method is simple, operation is convenient, the outer wall hole can be effectively blocked, and the permeabilityresistance is improved. In filling, self-weight of the concrete can be utilized, filling is facilitated, operation is convenient, the structure is simple, and hollowing and cracks are not prone to occurring.

Description

technical field [0001] The invention relates to the field of construction, in particular to a method for sealing an outer wall hole and a sealing filling hopper. Background technique [0002] In the field of construction, it is often necessary to reserve holes in the external wall in the early stage of construction, such as the part of the external scaffolding wall, the part of the cantilevered steel passing through the wall, etc. After the frame is dropped, the original hole is effectively sealed and filled to prevent water seepage from the external wall. The traditional method of later sealing is to directly shovel into the fine stone concrete manually. Because the grouting material is not dense and the joint between the new and old concrete is not tight, it is easy to hollow out and crack, causing water seepage hazards. In 2016, "a kind of filling formwork device for sealing the opening of building exterior wall (application number 201620969020.4)" appeared. The filling s...

Problems solved by technology

The traditional way of sealing in the later stage is to directly shovel into the fine stone concrete manually. Because the grouting material is not dense and the surrounding parts of the new and old concrete are not tight, it is easy to hollow out and crack, causing water seepage hazards

In 2016, "a kind of filling formwork device for sealing the opening of building exterior wall (application number 201620969020.4)" appeared. The filling slot of this patent is larger than the opening of the hole. When filling, the concrete needs to be manually pushed into the hole, and the operation will be slow. It is more troublesome, and the bottom is fixed with screws, and the inclined surface is supported with oblique support. The upper end is still easy to open, resulting in material leakage, which in turn causes the concrete to be poured and not compacted. The impermeability of the outer wall after the hole is sealed is poor, which can be further optimized
