Disc spring self-resetting joint connecting device

Abstract

The invention discloses a disc spring self-resetting joint connecting device, and belongs to the technical field of building structure engineering. The disc spring self-resetting joint connecting device is composed of a steel column, a cantilever short beam, a middle beam, a disc spring resetting device, a U-shaped damper, a connecting steel plate, a column stiffening rib, an anchoring plate, a beam stiffening rib and a high-strength bolt. The steel column and the cantilever short beam are welded, the cantilever short beam is in bolted connection with the middle beam through the connecting steel plate, and the disc spring resetting device and the U-shaped damper are arranged between upper and lower flanges of the steel beam. Under an earthquake action, joints bear bending moment and shearing force through the U-shaped damper and the connecting steel plate, energy input from the outside is consumed, after the earthquake action disappears, self-resetting of the joints is achieved throughthe disc spring resetting device, and a structure is not damaged or slightly damaged after an earthquake. A disc spring self-resetting joint connecting method is simple and convenient, the structureis simple, bolt connection is mostly adopted, assembling can be achieved, and if a component is damaged after the earthquake, the component can be replaced in time. The disc spring self-resetting joint connecting device can be widely applied to the technical field of shock absorption and energy dissipation of building structures.

Description

technical field [0001] The invention relates to the field of anti-seismic technology of building structures, in particular to a disc spring self-resetting node connection device which can be used for structures with self-resetting ability after earthquakes. Background technique [0002] Earthquake is a sudden natural disaster, which often brings huge disasters to human beings, resulting in property losses, casualties, and house collapses. The traditional anti-seismic design concept takes the protection of life as the primary goal, allowing the main anti-lateral force members of the structure to undergo plastic deformation to dissipate the seismic energy input into the structure, but this will lead to damage and residual deformation of the structural members, and ultimately make the structure difficult to repair damage and loss of function. [0003] Self-resetting nodes have the characteristics of being able to restore structural deformation after earthquakes, thereby reduci...
