External wall subsidence post-cast strip closing method and external wall subsidence post-cast strip closing device

Abstract

The invention provides an external wall subsidence post-cast strip closing method which comprises the following steps: main keels are vertically arranged on the inner side of an external wall of a basement, and the number of the main keels is at least two, so that a more stable supporting effect can be exerted; a soil retaining plate is vertically arranged on the outer side of a post-cast strip of the external wall, and waterstop bolts are arranged on the soil retaining plate, are perpendicular to the plate surface and are horizontally arranged; one end of each waterstop bolt is fixed to the soil retaining plate, the other ends of the waterstop bolts are fixed to the main keels, the two ends of the soil retaining plate are abutted against the outer side of the external wall, the soil retaining plate is compressed by the tensioning function of the waterstop bolts and isolates an area of the post-cast strip from the outside, and soil backfilling operation can be carried out first to prevent concrete from being exposed out for a long time. Compared with the traditional masonry method, with the adoption of the external wall subsidence post-cast strip closing method, greater lateral pressure can be borne through the soil retaining plate, no masonry panel structure is required, and a construction process is simple. The invention also provides an external wall subsidence post-cast strip closing device which can achieve the same technical effect.

Description

technical field [0001] The invention relates to the technical field of building construction, and more particularly relates to a method and device for sealing a pouring belt after the outer wall settles. Background technique [0002] The post-pouring belt is a temporary construction joint reserved at the corresponding positions of the foundation floor, wall, and beam in order to prevent the harmful cracks that may occur in the cast-in-place reinforced concrete structure due to uneven shrinkage or uneven settlement during construction. The post-pouring belt temporarily divides the structure into several parts, and after a certain period of time, the construction joint concrete is poured and tamped after the internal contraction of the components to connect the structure into a whole. [0003] The post-settlement pouring belt set between the garage and the main building is designed to be constructed after the main building is capped, but at the same time it is required to back...

AI Technical Summary

Problems solved by technology

The traditional construction method is to build a retaining wall at the position of the post-pouring belt and other construction methods, but the retaining wall built by the outer wall is relatively high, and it may be unable to withstand the large soil pressure during the backfilling process, resulting in tilting and collapse

And it is not possible to set the pull bolts in the post-pouring belt, but only to set the pull bolts on the retaining walls that have been poured on both sides. The height of the poured external wall concrete is too high, and quality defects such as mold expansion may occur, which will affect the post-casting. Belt construction
