Anti-seismic damper

Abstract

The invention relates to a damper, in particular to an anti-seismic damper. The anti-seismic damper comprises two mounting plates, wherein two mounting plates are each fixedly provided with an upper fixing plate and a lower fixing plate correspondingly; the upper fixing plate and the lower fixing plate are oppositely arranged; at least two movable columns are fixedly arranged on the upper fixing plate; the lower ends of the movable columns are inserted into damping cavities formed in the lower fixing plate and connected with a deformation damping assembly; fixed columns are fixedly arranged inthe damping cavities; a second electromagnet is fixedly arranged on the upper end of each fixed column and inserted into a cavity formed in each movable column; and a first electromagnet is arrangedon the upper end of each cavity in each movable column. According to the anti-seismic damper, the design is novel, the deformation damping assembly is matched with the two electromagnets, primary damping is achieved by the deformation damping assembly when shake occurs, and when the shock amplitude is large, the two electromagnets are electrified at the same time to generate repulsive force to achieve secondary damping, and thereby improving the damping effect.

Description

technical field [0001] The invention relates to a damper, in particular to an anti-seismic damper. Background technique [0002] At present, with the rapid development of my country's urbanization process and increasingly diversified use requirements, a large number of complex high-rise and super high-rise building structures are emerging, which brings new and huge challenges to seismic design. In addition to the need for building structures To meet the requirements of bearing capacity calculation, it is also necessary to be able to achieve performance-based design goals. [0003] The existing building dampers have some defects in the use process: first, when the damping is small, it is impossible to achieve buffering and anti-seismic for large vibrations; second, when the damping is large, it is impossible to effectively buffer small vibrations poor. Contents of the invention [0004] The object of the present invention is to provide an anti-seismic damper to solve the p...
