The shear wall shell is surrounded by an arc-shaped inner steel plate, an arc-shaped outer steel plate, a left side plate and a right side plate. The present invention adopts the combined shear key of stud and pull screw, which has good ductility and anti-fatigue performance. The combined shear key can enhance the cooperative working ability of inner and outer steel plates and interlayer concrete, and improve the bearing capacity and deformation capacity of the shear wall , all components are mass-produced in the factory, which significantly improves construction efficiency and can effectively solve the problems of poor ductility, insufficient seismic performance and complex construction structures of traditional reinforced concrete shear walls. It can be widely used in high-rise and super high-rise buildings, and can also be expanded It has important engineering practical significance and social and economic benefits.
