Embodiment 1

[0039] A self-resetting member based on parallel high-strength steel ring springs, its structure see figure 1 As shown, the inner wall is processed with the outer cylinder of the first annular groove 23, the ring spring mechanism placed in the annular groove and composed of multiple sets of parallel ring spring groups, and the bottom end slides into the outer cylinder and Through the inner rod 1 of the ring spring mechanism, the inner rod 1 is also processed with a second annular groove 33, and the inner parts of the upper and lower ends of the ring spring mechanism are placed in the second annular groove 33, and can respectively correspond to the second annular groove 33. The upper and lower ends of the annular groove 33.

[0040] see you again figure 1 As shown, the outer cylinder includes an upper outer cylinder 21 and a lower outer cylinder 22 which are screwed into each other, and the upper outer cylinder 21 and the lower outer cylinder 22 are respectively processed with...

Abstract

The invention relates to a self-resetting member based on parallel high-strength steel ring springs. The resetting member comprises an outer cylinder piece with the inner wall provided with a first annular groove, a ring spring mechanism provided with multiple ring spring sets in parallel and arranged in the annular groove, and an inner rod with the bottom end slidably extending into the outer cylinder piece and penetrating through the ring spring mechanism, the inner rod is further provided with a second annular groove, and the inner side portions of the upper and lower ends of the ring spring mechanism are separately placed in the second annular groove and correspondingly abut against the upper and lower ends of the second annular groove respectively. Compared with the prior art, energydissipation is achieved through friction between the contact surfaces of the high-strength steel ring springs, and the member has the self-resetting function. By adjusting the wedge rate, size and number of the high-strength steel ring springs, the processing mode of the contact surfaces and pretightening force of the high-strength steel ring springs, the anti-seismic requirement of multiple aspects can be met.

Description

technical field [0001] The invention belongs to the technical field of anti-shock and shock absorption of structural engineering, and relates to a self-resetting component based on parallel high-strength steel ring springs. Background technique [0002] With the advancement of construction technology and the increase of people's investment in construction, the collapse of building structures and the number of casualties have been effectively controlled, but the economic losses and social impact caused by earthquakes are still very large. If the structural function can be quickly restored after the earthquake, the indirect economic loss can be effectively reduced. However, at this stage, the building has not collapsed after the earthquake, but it has a large residual deformation, which is difficult to repair and becomes a standing ruin, facing a state of forced demolition. At present, most of the mature damper components only have the ability to dissipate earthquake energy. ...
