Abstract

The invention discloses a large-deformation pulley set self-centering buckling restraint support. A rectangular middle casing pipe, a rectangular inner casing pipe located in the rectangular middle casing pipe, a rectangular outer casing pipe sleeving the rectangular middle casing pipe, two outer end plates arranged at the two ends of the rectangular middle casing pipe, two inner end plates arranged at the two ends of the rectangular inner casing pipe, pulleys arranged on the sides, close to the rectangular inner casing pipe, of the inner end plates, a first pre-pulling rod set, a second pre-pulling rod set and a core plate arranged between the rectangular middle casing pipe and the rectangular outer casing pipe, wherein the first pre-pulling rod set and the second pre-pulling rod set arearranged in the rectangular inner casing pipe. One end of the core plate is connected with one end of the rectangular middle casing pipe, and the other end of the core plate is connected with the other end of the rectangular outer casing pipe. After the first pre-pulling rod set is wound around the pulley connected with the inner end plate at one end, the two ends of the first pre-pulling rod setare anchored to the outer end plate at the other end and the inner end plate at the other end correspondingly. After the second pre-pulling rod set is wound around the pulley connected with the innerend plate at the other end, the two ends of the second pre-pulling rod set are anchored to the outer end plate at one end and the inner end plate at one end correspondingly.

Description

technical field [0001] The invention belongs to the field of civil engineering, and relates to a large-deformation pulley group self-centering buckling restraint 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] To control the residual deformation of the structure, self-centering buck...
