[0002] A prefabricated building refers to a building in which a large amount of on-site operation work in the traditional construction method is transferred to a factory. Building components and fittings (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory and transported to the construction site of the building, and are assembled and installed on-site through reliable connection methods. In the use process of the existing prefabricated shear walls for prefabricated buildings, there are at least the following disadvantages: 1. The connection of the existing prefabricated shear walls for prefabricated buildings is not firm enough and the stability is poor; 2. The installation and disassembly of the existing prefabricated shear walls for prefabricated buildings are troublesome. Therefore, we introduce a new prefabricated shear wall for prefabricated buildings. Content of the Utility Model
