Post-cast strip wall formwork structure and construction method for advanced water stop of outer wall post-cast strip

Abstract

The invention is suitable for the technical field of wall engineering, and provides a post-cast strip wall formwork structure and an outer wall post-cast strip advanced water stop construction method. The post-cast strip wall formwork structure comprises supporting assemblies, inner side formworks, embedded steel plates and steel cover plates, outer wall concrete is arranged on the left side and the right side of a post-cast strip, the supporting assemblies are fixedly arranged on the outer wall concrete on the two sides, and fast and easy closing-up nets or fish scale water stop pieces are arranged between the post-cast strip and the outer wall concrete; the inner sides of the embedded steel plates are welded to the supporting assembly and fixedly arranged on the outer side face of the outer wall concrete, and the embedded steel plates are located on the two sides of the post-cast strip. The inner sides of the two ends of the steel cover plate are welded to the outer sides of the embedded steel plates located on the two sides of the post-cast strip correspondingly, and the steel cover plate seals and covers an outer opening of the post-cast strip. And the waterproof layer is laid on the outer sides of the concrete and the steel cover plate. The structure is simple, the wall manufacturing period is greatly shortened, the labor cost is greatly saved, the problems of early closing difficulty and measure cost of the basement outer wall are solved, the closing progress is accelerated, and the construction period is shortened.

Description

technical field [0001] The invention belongs to the construction engineering technology, in particular to a construction method of a post-pouring zone wall support formwork structure and an outer wall post-pouring zone advanced water stop. Background technique [0002] In the construction process, the existence of the back-casting belt on the outer wall has a great influence on the waterproof quality of the outer wall and the progress of the backfilling of the fertilizer tank. The plane layout conversion can greatly speed up the overall construction progress, reduce the risk of external wall leakage, and bring greater benefits. [0003] At present, the technology that is relatively close to the present invention is that the post-casting zone of the outer wall adopts the method of bricklaying and sealing, so as to realize the advance insertion waterproofing and backfilling construction. In the actual implementation process, often because the depth of the basement is deep and...

AI Technical Summary

Problems solved by technology

In the actual implementation process, often because the basement is deep and the distance between the basement structure and the foundation pit support is relatively close, it is difficult to close the construction by laying bricks

At the same time, in order to ensure the bonding effect between the waterproof layer and the brick building envelope, a plaster layer is generally added on the outside, resulting in increased costs and delayed progress
