Problems solved by technology
The external steel restraint members of the traditional steel plate shear wall have a complex structure and are cumbersome in design and construction. The traditional reinforced concrete restraint slabs increase the difficulty of transportation and construction due to their large size, and are not conducive to daily maintenance and post-earthquake repair

The invention relates to an assembly type prefabricated-steel-plate shear wall. The shear wall comprises an internal energy-consumption steel plate and external precast reinforced concrete restraining plates, wherein the internal energy-consumption steel plate is a steel plate with vertical joints, and the rigidity and the bearing capacity of a single shear wall body are changed by adjusting parameters including space between the vertical joints, as well as lengths and positions of the vertical joints; the external precast reinforced concrete restraining plates comprise precast concave-convex-groove reinforced concrete restraining plate bodies, angle steels and U-steels; a plurality of the concave-convex-groove reinforced concrete restraining plate bodies are connected by high-strength bolts, the U-steels and the angle steels are connected by high-strength bolts, and a steel frame for the external precast reinforced concrete restraining plates is formed; the precast concave-convex-groove reinforced concrete restraining plate bodies are fixed inside the steel frame by high-strength bolts; the external precast reinforced concrete restraining plates are connected with the internal energy-consumption steel plate by connection bolts to form an overall system. Bolt holes are reserved based on the vertical joints formed in the internal energy-consumption steel plate.
Description
technical field [0001] The invention relates to an assembled prefabricated steel plate shear wall, which belongs to the technical field of structural engineering. Background technique [0002] With the development of the construction industry and the growth of urban population, urban land resources are increasingly precious, which promotes people's demand for high-rise buildings. At present, the commonly used anti-lateral force components in high-rise buildings are mainly reinforced concrete shear walls, but the reinforced concrete shear walls have too large rigidity, poor ductility, too large increases the self-weight of the structure, and cracks occur earlier under the action of earthquakes , The disadvantages such as difficulty in post-earthquake repair limit its application. [0003] Steel plate shear wall is a new type of lateral force-resisting component. Compared with reinforced concrete shear wall, its self-weight is smaller, which greatly reduces the seismic action...
