Also known as wind-resistant walls, earthquake-resistant walls or structural walls, are generally made of reinforced concrete. With the development of the building industry, buildings with high-rise and frame structures are increasing continuously, most buildings are built in a cast-in-place concrete mode due to the requirements for high anti-seismic performance and strong waterproof performance, and before concrete is poured, a shear wall prefabricated frame needs to be built on the building site. The shear wall prefabricated frame is a temporary supporting structure, is manufactured according to design requirements, enables a concrete structure and a member to be formed according to specified positions and geometric dimensions, keeps the correct positions of the concrete structure and the member, and bears the self weight of a building template and external loads acting on the building template. In the building construction process, the shear wall template for pouring concrete needs to be reinforced, wherein the procedure of erecting the reinforced template accounts for more than 95% of the working period of the whole template. The process has high technical requirement, and the reinforcing process is complicated and tedious, so that the process is a difficult problem for worker construction in the whole building industry.
When the shear wall template reinforcing member in the prior art is used, more attention is not paid to the end reinforcement of a shear wall, and due to the influence that the end reinforcement of the shear wall is not in place or is inconvenient to reinforce, the conditions of mold expansion and slurry leakage are easily caused at the end of the shear wall when concrete is poured, so that the forming quality of the concrete is poor.
Therefore, it is an object of the present invention to provide a reinforcing apparatus and a reinforcing method for a shear wall end form, which are specially adapted for industrial and civil buildings, so as to effectively avoid the quality defects.
