Damping mesosphere embedded double steel plate concrete composite assembly type shear wall and its mounting method

摘要

The present invention relates to a damping intermediate layer embedded double steel plate concrete composite assembly type shear wall and belongs to the field of construction technology. The present invention comprises a double steel plate layer, a double damping intermediate layer and a concrete layer. The shear wall is connected by a retaining bolt connecting member, the double steel plate layer includes two first steel plates in the longitudinal direction and a second steel plate in the lateral direction, and the damping intermediate layer is the first damping intermediate. Includes a layer and a second damping intermediate layer, the first damping intermediate layer is located between the first steel plate and the concrete layer, the second damping intermediate layer is covered with a retaining bolt connecting member, and the steel pipe is the second damping intermediate layer. Covered with, the retaining bolt connecting member includes a restraint tie bar with a dam and a high strength restraint tie bar unit. According to the present invention, by adding a damping layer to the double steel plate concrete composite shear wall, energy can be consumed by shear deformation of the damping material and the steel plate, and the damping material and the concrete cross section, and the slip of the steel plate and the concrete cross section is controlled. It enables and effectively improves the damping of the structure, reduces the seismic response of the structure, and improves the energy consumption and vibration absorption capacity of the structure.
