Double-sided composite shear walls are made of two prefabricated reinforced concrete panels, which are connected to form a wall panel component with a middle cavity through trusses or connectors in the factory. After on-site installation, concrete is poured to fill the middle cavity to form a concrete wall. Double-sided composite wall panels are produced through fully automatic imported assembly lines with a high degree of automation, very high production efficiency and processing accuracy, as well as good integrity and excellent waterproof performance.

[0066] This embodiment proposes a prefabricated shear wall body combination form, which splits the wall body component into two shell membrane form components, both of which are equipped with horizontal stirrups, horizontal steel bars and longitudinal steel bars of the shear wall. The truss bars or connectors of the double-sided composite shear wall are replaced by horizontal stirrups. The horizontal stirrups carried by the two components are arranged at intervals. After the two components are combined, a cavity for post-cast concrete is formed in the middle. After concrete is poured in the cavity, the horizontal stirrups of the two components form an effective tensile force after the concrete solidifies, so that the two components can be effectively combined into a complete shear wall body.

[0067] The top of the lower prefabricated shear wall can be reserved with dowel bars, and the bottom of the upper shear wall is provided with grooves extending along the length of the wall. After the steel bars are inserted into the grooves, the two floors can be combined by pouring concrete in the wall cavity.
