Jointless construction structure combining SCC (self-compacting concrete) and common concrete

Abstract

The invention discloses a jointless construction structure combining SCC (self-compacting concrete) and common concrete. The jointless construction structure comprises a reinforced band, the high-performance SCC, two non-reinforced bands, close-drilling steel wire meshes; horizontal temperature reinforcement bars, upper reinforcement bars, lower reinforcement bars, vertical reinforcement bars and concrete protecting layers, wherein the high-performance SCC is uniformly arranged in the reinforced band; the close-drilling steel wire meshes are arranged between the high-performance SCC and the two non-reinforced bands; the upper ends of the vertical reinforcement ribs are connected with the upper reinforcement ribs; and the lower ends of the vertical reinforcement ribs are connected with the lower reinforcement ribs. The jointless construction structure disclosed by the invention achieves the beneficial effects that protecting and waterproof measures for a post-cast strip, the post-cast strip cleaning work, and a reinforcement part of the post-cast strip are eliminated; the construction period is shortened, the engineering cost is reduced, the construction is simplified, the engineering quality is improved, the homogeneity and the stability are high, and the concrete hardening period is short; the construction structure is simple and convenient, and no complex process is adopted, thereby saving the manpower and shortening the construction period; and the concrete self-waterproof effect is improved.

Description

technical field [0001] The invention relates to a seamless construction structure, in particular to a seamless construction structure combining SCC and ordinary concrete. Background technique [0002] According to the national standard, a post-cast belt is installed every 30-40m for the structural foundation of the underground garage, and water-stop plates are installed on both sides of the belt. After the concrete shrinks for 40-50 days, fill the joints with shrinkage-compensating concrete. This design provision is justified due to shrinkage problems with ordinary concrete. However, the construction of the post-cast belt is cumbersome and the construction period is prolonged. If it is not handled properly, it will become a hidden danger of water seepage. With the development and innovation of materials and technologies, the seamless construction technology combined with self-compacting concrete (SCC high-performance concrete) and ordinary concrete emerged as the times requ...
