A kind of steel plate installation structure and construction method of back-casting belt of basement exterior wall

Abstract

This application relates to the technical field of post-cast strips in basements, and in particular to a steel plate installation structure for post-cast strips on exterior walls of basements, including exterior walls. There are several steel plates arranged longitudinally on the outer side of the belt, and the steel plates cover the post-casting belt. The side of the steel plate close to the steel mesh is fixedly connected with a connecting shaft, the end of the connecting rod passes through a mounting plate, and the two ends of the mounting plate extend to the outside The inner side of the wall is close to the inner side of the outer wall, and one end of the connecting shaft passing through the mounting plate is threadedly connected with a nut. This application has the effect of being able to improve the waterproof performance of the exterior wall.

Description

technical field [0001] The present application relates to the technical field of basement post-casting belts, in particular to a steel plate installation structure and construction method of basement external wall post-casting belts. Background technique [0002] The post-pouring belt is a temporary construction joint at the corresponding position of the foundation floor, wall or beam in order to prevent the harmful cracks that may occur in the poured reinforced concrete structure due to uneven temperature and shrinkage during construction. The structure is temporarily divided into several parts. After the internal shrinkage of the components for a certain period of time, the construction joint concrete is poured and tamped to connect the structure into a whole. [0003] The traditional post-casting technology includes masonry work well protection method, post-casting tape advanced water-stop method and precast concrete masonry method, and there are many problems in the cons...

AI Technical Summary

Problems solved by technology

Using the masonry working well protection method, when the outer wall is high, the working well is deep, the later construction is difficult, there are safety hazards, and it is easy to accumulate water, produce cracks, and collapse after backfilling; The construction process is complicated, it is difficult to formwork, reinforce and dismantle the protruding parts, and the cost of labor and materials is large; the precast concrete masonry method is adopted, the weight of the prefabricated block is large, and it needs to be processed on site, the process is complicated, and the protection of the finished prefabricated block is difficult, etc.

[0004] In the related technology, an advanced waterproof construction technology of steel plates attached to the post-casting belt of the basement exterior wall is proposed. The steel plate is used to replace the traditional post-casting belt to build the working well and prefabricated blocks. The construction is convenient, and the steel plate and the post-casting belt are welded and connected After the steel plate is installed, the waterproof layer and protective layer can be constructed, which can be constructed at the same time as the outer wall, and the earthwork can be backfilled at the same time, which achieves the effect of advanced waterproofing, and avoids some disadvantages of the post-pouring belt, and solves the waste of traditional technology. Difficulties in manpower, material resources, long construction period and difficult construction

[0005] In view of the above-mentioned related technologies, the inventor believes that after the steel plate is installed, when the backfill soil is not compacted enough when pouring concrete on the post-pouring belt, the poured concrete will squeeze the steel plate toward the backfill soil, deforming the steel plate, and then destroying it. Waterproof layer, making the waterproof effect less than expected
