Steel wire rope damping shock absorption expansion joint and bridge

Abstract

The invention discloses a steel wire rope damping shock absorption expansion joint and a bridge. The steel wire rope damping shock absorption expansion joint comprises a steel wire rope damper and twosymmetrically-arranged anchoring structures, the steel wire rope damper is fixed between the two anchoring structures, and side longitudinal beams are arranged at the top edges of the opposite sidesof the two anchoring structures. A waterproof structure is arranged between the two side longitudinal beams, and the steel wire rope damper and the side longitudinal beams are both parallel to the side walls of the anchoring structures. The steel wire rope damper is adopted as an energy dissipation component, so that the expansion joint has the energy dissipation and shock absorption functions, and the structure is simple. The telescopic function is achieved through the stretching out and drawing back operations of a diagonal bracing supporting system, the displacement requirement of an engineering structure during the temperature changing process is met, the movement is more flexible, the structure is novel, and the installation and maintenance are both extremely convenient.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a steel wire rope damping shock-absorbing expansion joint and a bridge. Background technique [0002] "Expansion with heat and contraction with cold" is the most basic physical property of structures or structural components. For bridge structures, when the temperature rises, the beam body will elongate; when the temperature drops, the beam body will shorten. This characteristic has an important impact on the force of the bridge structure, affecting the use and safety of the structure. Expansion joints are provided to accommodate deformations caused by temperature changes. [0003] At present, the expansion joints commonly used in bridges include modular expansion joints and comb-tooth plate expansion joints.

Problems solved by technology

In recent years, these two types of telescopic devices have made some technical progress in shock and noise reduction through technological innovation, but because of the lack of a clear damping system, their energy dissipation and shock absorption effects are very limited, and they have not fundamentally overcome the impact of earthquakes.
