Self-resetting energy consumption connecting device for fabricated shear wall

Abstract

The invention discloses a self-resetting energy consumption connecting device for a fabricated shear wall. The self-resetting energy consumption connecting device comprises energy consumption connecting pieces which are symmetrically arranged at bottom corners of two ends of a prefabricated wall plate, an upper wall plate and a lower wall plate are connected into a whole through a prestress system, the energy consumption connecting pieces comprise two replaceable plates, the two replaceable plates are vertically and symmetrically arranged on the inner surface and the outer surface of the upperwall plate, a plurality of bolt holes are vertically formed in the two ends of the replaceable plates, screw rod through holes are correspondingly formed in the upper wall plate, bolt rods sequentially penetrate through the bolt holes and the screw through holes to connect the two replaceable plates and the upper wall plate together, and the bolt rods can slide up and down in the bolt holes and the bolt through holes. According to the self-resetting energy consumption connecting device, the bolt rods slide in the bolt holes, the earthquake capacity is consumed through friction force generatedby sliding of the bolt rods in the screw holes, and when the earthquake action is reduced, the building structure returns to the initial position through the prestressing force and the gravity of thewall, so that self-resetting, energy consumption and seismic mitigation of the building structure are achieved.

Description

technical field [0001] The invention belongs to the technical field of recoverable functional structures, in particular to a self-resetting energy-dissipating connection device for a prefabricated shear wall. Background technique [0002] At present, the "three-level, two-stage" seismic fortification target is mainly adopted; however, due to the complexity and uncertainty of earthquakes, building structures are often subjected to earthquakes that exceed their own seismic fortification intensity; although according to the existing seismic fortification Fortification targets, most of the building structures will not collapse and cause major casualties, but the local damage of the building structure caused by the earthquake is difficult to repair, which will seriously affect the normal life of people after the earthquake; The long-term failure to restore the function of the building has caused huge losses to the social economy; therefore, the current goal of earthquake resistan...
