Post-cast strip plugging structure and construction method thereof

Abstract

The invention provides a post-cast strip plugging structure and a construction method thereof. The post-cast strip plugging structure comprises longitudinal steel bars, fixing steel bars, supporting steel bars, a plugging net, water-stopping steel plates and transverse steel bars; the plugging net is vertically arranged at the interface between the post-cast strip side and the plate side; the water-stopping steel plates are horizontally arranged in the middle of the plugging net and penetrate into a post-cast strip from the interior of the plate side; spaced fixing steel bars are connected tothe water-stopping steel plates perpendicular to the plate surfaces of the water-stopping steel plates; the horizontal longitudinal steel bars and the transverse steel bars are arranged at the upper ends and the lower ends of the fixing steel bars; the longitudinal steel bars and the transverse steel bars are perpendicular to each other; and the fixing steel bars, the plugging net and the water-stopping steel plates form a grid structure on the vertical surface, and one supporting steel bar is arranged between every two opposite fixing steel bars. The construction method is scientific and easyto operate, the overall combination of post-cast strip concrete is effectively improved, the occurrence of obvious cracks is avoided, and the good construction quality can be ensured.

Description

technical field [0001] The invention belongs to the technical field of post-cast belt treatment in municipal engineering, and specifically relates to a post-cast belt sealing structure and a construction method, which realizes the perfect fit between the post-cast belt reinforcement and the sealing structure, and prevents post-cast belt leakage, cracks, cavities, Problems such as exposed ribs appear to ensure the construction quality of the post-casting belt. Background technique [0002] It is found in the post-casting belt construction of underground buildings that currently the method of pure steel wire mesh sealing is mostly used. Although the steel mesh sealing is greatly convenient for the old technology of formwork sealing, but because the steel mesh sealing method is used in engineering practice, the construction is random. Due to the reasons such as strong resistance and narrow construction space for sealing, the construction process is complicated and time-consumin...

AI Technical Summary

Problems solved by technology

This method effectively solves the problem that the construction of the post-cast belt adopts pure steel wire mesh plugging structure, the randomness of the construction, the poor sensory quality of the formed section, the serious swelling and grout leakage of the concrete pouring, the many interface voids, the difficulty of cleaning the post-cast belt, and the interface after construction of the post-cast belt. Large cracks and other issues
