Self-resetting device for swing structure

Abstract

The invention relates to a self-resetting device for a swing structure. The self-resetting device for the swing structure comprises a core shaft, a first end plate, a dish-shaped spring combination, a second end plate, an outer barrel wall and a connecting plate. The dish-shaped spring combination is arranged at the outer part of the core shaft in a sleeving mode. The inner side surfaces of the first end plate and the second end plate are correspondingly tightly attached to the two ends of the dish-shaped spring combination. Axial limiting is conducted on the first end plate and the second end plate through the outer barrel wall. The connecting plate is fixedly connected with the outer barrel wall. When the core shaft is pulled, the core shaft displaces, the second end plate is driven to displace inwards and extrudes the dish-shaped spring combination. When the core shaft is pulled, the core shaft displaces reversely, the first end plate is driven to displace inwards and extrudes the dish-shaped spring combination. The self-resetting device of the swing structure is vertically fixed between a base beam and the swing structure. The self-resetting device for the swing structure is simple in manufacture, economic, applicable, stable in self-resetting performance, convenient in post-seismic maintenance and extensive in application and popularization value.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a self-resetting device for a rocking structure. Background technique [0002] The rocking structure is to loosen the constraints between the structure and the foundation or between the components, so that the contact surface between the structure and the foundation or components has only compressive capacity but no tensile capacity, and the structure will sway under the action of the earthquake. The structure resets to form a rocking structure and a self-resetting structure. Existing studies have shown that the sway of the structure reduces the seismic action and the ductility design requirements of the structure itself, reduces the earthquake damage, and saves the structural cost. Rocking structure is an important realization form of recoverable functional structure. It can be used not only for energy dissipation and shock absorption of new buildings, but also for seism...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the existing swing wall structure adopts prestressed tendons buried through the structural members (such as the wall) and the foundation, which is not conducive to the arrangement of the openings on the wall, and it is necessary to prestress the wall on the wall. Leaving holes, the operation steps are more troublesome; the anchorage construction of prestressed tendons on the bottom of the foundation beam is difficult
