Anti-seismic reinforcing steel plate shear wall for existing building

The invention provides an anti-seismic reinforcing steel plate shear wall for an existing building, which relates to the technical field of structural engineering, and adopts the scheme that the anti-seismic reinforcing steel plate shear wall comprises a frame and an infilled steel plate, edge constraint components are mounted on four edges of the infilled steel plate, and every two adjacent edge constraint components are hinged to each other; buckling restraining components are installed on the front plate face and the rear plate face of the infilled steel plate, the ends of the buckling restraining components are hinged to edge restraining components, the upper edge restraining component and the lower edge restraining component of the infilled steel plate are connected with a frame beam through part of connecting pieces, and a central fulcrum cable clamp is arranged in the middle of the infilled steel plate. The central fulcrum cable clamp is connected with a self-resetting inhaul cable, and the self-resett
