Energy consumption connecting device for assembled shear wall

Abstract

The invention discloses an energy consumption connecting device for an assembled shear wall. The energy consumption connecting device for the assembled shear wall comprises energy consumption connecting systems and a prestressing system, wherein the energy consumption connecting systems are symmetrically arranged at bottom corners of two ends of prefabricated wallboards; the upper ends of the energy consumption connecting systems are connected with the upper prefabricated wallboard, and the lower ends of the energy consumption connecting systems are connected with the lower prefabricated wallboard; the prestressing system is arranged on the central axis of the prefabricated wallboards; and the upper prefabricated wallboard and the lower prefabricated wallboard are connected into a whole through the prestressing system. According to the energy consumption connecting device for the assembled shear wall, the upper and lower prefabricated wallboards are connected into a whole through the energy consumption connecting systems and the prestressing system, and generate swing deformation cooperatively under the action of earthquake; the prestressing system is arranged on the central axis of the prefabricated wallboards, and a wall body can be controlled to swing by utilizing prestress and wall body dead weight; the energy consumption connecting systems are arranged at the highly stressed tension-compression corner parts of the wall body, reliable energy consumption connection is provided by the energy consumption connecting systems, brittle crushing damage to the concrete corner parts of the wall body is avoided, and the applicable seismic grade range of the structure is expanded.

Description

technical field [0001] The invention belongs to the technical field of structural connection of assembled shear walls, in particular to an energy dissipation connection device for assembled shear walls. Background technique [0002] With the vigorous development of prefabricated buildings, prefabricated shear wall structures have received extensive attention for their superior lateral stiffness, but the early prefabricated slab structures exposed many problems in application, such as poor structural seismic performance, connection Insufficient performance and serious damage to the joints of components have severely restricted the development of prefabricated buildings; in order to solve the above problems, scholars at home and abroad have proposed a variety of solutions around connection technology, including traditional shear key connection, grouting connection and other wet connection methods And dry connection methods such as bolted connection, welded connection and prest...
