Self-centering friction energy consumption support for large deformation pulley block

Abstract

The invention discloses self-centering friction energy consumption support for a large deformation pulley block. The self-centering friction energy consumption support for the large deformation pulleyblock comprises a rectangular middle sleeve, a rectangular inner sleeve located in the rectangular middle sleeve, a rectangular outer sleeve sleeved outside the rectangular middle sleeve, two outer end plates arranged at two ends of the rectangular middle sleeve, two inner end plates arranged at two ends of the rectangular inner sleeve, pulleys arranged on the sides, close to the rectangular inner sleeve, of the inner end plates, a first set of pre-pull rods and a second set of pre-pull rods arranged in the rectangular inner sleeve, a friction energy consumption component connecting a rectangular middle sleeve baseplate and a rectangular outer sleeve baseplate, first connecting plates arranged at one end of the rectangular middle sleeve and connected with the rectangular middle sleeve andsecond connecting plates arranged at the other end of the rectangular middle sleeve and connected with the rectangular outer sleeve. After the first set of pre-pull rods bypass the pulley connected with the inner end plate at one end, two ends of the first set of pre-pull rods are anchored respectively to the outer end plate at the other end and the inner end plate at the other end. After the second set of pre-pull rods bypass the pulley connected with the inner end plate at the other end, two ends of the second set of pre-pull rods are anchored respectively to the outer end plate at one endand the inner end plate at one end.

Description

technical field [0001] The invention belongs to the field of civil engineering and relates to a large-deformation pulley block self-centering frictional energy consumption support for reducing earthquake disasters of engineering structures. Background technique [0002] Earthquakes bring extremely serious disasters to human beings. The traditional seismic design adopts the ductility design method, that is, under the action of an earthquake, through the early yield and failure of some structural components, but the overall function will not be lost, relying on the plastic deformation of the components to dissipate most of the seismic energy, so as to achieve The purpose of ensuring the safety of the main structure. However, the plastic deformation of components will lead to large residual deformation of the structure after the earthquake, which will greatly increase the difficulty of structural repair. [0003] In order to control the residual deformation of the structure, ...
