Abstract

The invention provides a concrete shear wall with a lead core energy-consuming device and a built-in steel plate and a manufacturing method, and belongs to the field of earthquake resistance and disaster prevention and reduction of engineering structures. Connection plates with bolt holes are welded to the middle of the inner side of a structural steel frame, and studs are welded to the two sides of the steel plate with round holes distributed in a diagonal mode. The steel plate is connected with the connection plates with the bolt holes in a splicing and fastening mode through high-strength bolts, cake-shaped lead blocks with round holes are embedded in the round holes distributed in the diagonal mode, tie bars penetrate through the cake-shaped lead blocks with the round holes to be bound with reinforcing mats, and concrete is poured in the two sides of the steel plate with the round holes distributed in the diagonal mode to form the concrete shear wall. Under the action of earthquakes with common intensity, the steel plate shear wall provides sufficient rigidity for a structure; the tie bars and the lead blocks extrude to dissipate part of earthquake energy, and house structures can be normally used; under the action of earthquakes with rare earthquake intensity, the tie bars and the studs are effectively bound with a reinforced concrete wall, the steel plate is prevented from buckling outside a plane, and the structural earthquake resistance is enhanced.
