Hinge device with unequal tension and compression toughness and assembly method

Abstract

The invention belongs to the technical field of engineering structure seismic resistance, and relates to a hinge device with unequal tension and compression toughness and an assembly method. The device comprises a pressure spring for providing an anti-compression restoring force, a tension spring for providing an anti-tension restoring force, a pressure spring baffle for applying a pre-compression force to the pressure spring, a stop block for limiting springback of the pressure spring and the tension spring, a tension spring baffle for limiting springback of the tension spring, an outer pipe for driving the pressure spring baffle and the tension spring baffle, and a tension spring sealing plate for limiting the springback of the tension spring. Aiming at obvious plastic hinge formation and residual displacement of a traditional anti-seismic structure, the device replaces stressed steel bars and the like in an original plastic hinge area to carry out stress service, so that a novel structure has the same rigidity, bearing capacity and higher deformability, and does not generate plastic and residual deformation; aiming at the problem that lateral deformation of a prestress self-resetting structure system is large, the deformation mode and the stress process of the prestress self-resetting structure system are roughly the same as those of a traditional rigid connection structure, and additional increase of lateral deformation is not caused; and the device can be repaired and replaced, the initial state can be recovered through large deformation, and the requirement for replacement is extremely low in multiple times of earthquake service.

Description

technical field [0001] The invention belongs to the technical field of anti-seismic engineering structures, and relates to a tension-compression unequal ductile hinge device and an assembly method, in particular to a new type of construction structural engineering component, which is used to be installed in the potential area of ​​the plastic hinge of a traditional structural member, such as a beam end of a frame beam 1. The foot of an anti-seismic wall and the bottom of a frame column, specifically relating to a self-resetting axial force-bearing device with different compressive and tensile properties, which is composed of an inner and outer tube and a Belleville spring washer. Background technique [0002] Earthquake disasters threaten human society all the time. Buildings with various structural components firmly connected by joints have good seismic performance, but modern seismic structures generally endow the structure with good ductility through the plastic developme...
