Concrete shear wall with lead core energy-consuming device and built-in steel plate and manufacturing method

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.

Description

technical field [0001] The invention relates to a built-in steel plate concrete shear wall with a lead core energy dissipation device and a manufacturing method thereof, belonging to the technical field of earthquake resistance and disaster prevention and mitigation of engineering structures. Background technique [0002] In the super high-rise hybrid structure system, the shear wall is an important lateral force-resisting component. Under earthquake action, the core tube shear wall not only bears most of the seismic shear force, but also plays an important role in dissipating seismic energy, and is a key component in the seismic design of super high-rise hybrid structural systems. If traditional reinforced concrete shear wall components are used in super-limit high-rise buildings, thicker walls need to be designed to resist the corresponding horizontal earthquake action, resulting in waste of building materials and space, increasing the structural weight, and resulting in s...
