Description

Technical Field

[0001] The present invention relates to the technical field of building structures, and more particularly to a disassembly-free formwork shear wall. Background Art

[0002] The shear walls of traditional buildings require on-site formwork support and reinforcement before pouring concrete. The formwork also needs to be removed later. On the one hand, the process is cumbersome and affects the construction period. On the other hand, material loss is serious, which wastes money and manpower and easily pollutes the environment.

[0003] Patent No. CN201821006510.X discloses a vertical connection structure of a steel tube concrete shear wall and a reinforced concrete shear wall, including a steel tube concrete shear wall and a reinforced concrete shear wall located above it, wherein the steel tube concrete shear wall includes a plurality of mutually sleeved steel tubes, concrete poured into the steel tubes, and fasteners fixed on the inner wall of the steel tubes. Concrete is poured into the mutually sleeved steel tubes and after consolidation, it is integrated with the steel tubes through fasteners to jointly bear the load. Vertical connecting steel bars are provided inside the reinforced concrete shear wall. The vertical connecting steel bars are The steel tube concrete shear wall is extended downward, and the vertical connecting steel bars are extended upward into the upper reinforced concrete shear wall, serving also as the vertical reinforcement of the reinforced concrete shear wall to connect the steel tube concrete shear wall and the reinforced concrete shear wall. This invention solves the vertical connection structure between the steel tube concrete shear wall and the reinforced concrete shear wall. The lower part is a circular steel tube concrete shear wall to bear huge vertical loads, and the upper part is set as a low-cost reinforced concrete shear wall because the load it bears is small. The connection between the two is simple and stable, and the project cost is saved to the maximum extent while ensuring the structural strength.

[0004] One solution to this problem is to use prefabricated shear walls. However, prefabricated shear walls are expensive, generally higher than traditional cast-in-place buildings. On-site construction is also inconvenient and poses safety risks. To address this issue, the present invention has designed a new type of shear wall with no-dismantling formwork. This wall is composed of steel bar molded products, connectors, and high-precision no-dismantling formwork. Summary of the Invention

[0005] 1. Technical problems to be solved
