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. Damage caused by structure or telescoping device itself

Embodiment 1

[0043] Such as Figure 1-4 As shown, the present invention provides a steel wire rope damping shock-absorbing expansion joint, including a wire rope damper 2 and two anchor structures 1 symmetrically arranged, the steel wire damper 2 is fixed between the two anchor structures 1, and the two A side longitudinal beam 6 is arranged on the top edge of the opposite side of the anchor structure 1, and a waterproof structure is arranged between the two side longitudinal beams 6. The wire rope damper 2 and the side longitudinal beam 6 are all parallel to the side wall of the anchor structure 1 (i.e. Baffle plate 25) arrangement.

[0044]The invention adopts the steel wire rope damper as the energy dissipation member, so that the expansion joint has the function of energy dissipation and shock absorption, and the structure is simple; the supporting system of the single joint only has side beams and no middle beams, so scissors bracing is not needed, and the two side longitudinal beams ...

Embodiment 2

[0050] Such as Figure 5-10 As shown, in order to adapt to the gap size of different expansion joints and improve the structural bearing capacity and shock absorption effect, on the basis of Embodiment 1, the steel wire rope damping shock absorption expansion joint of the present invention can also include a top layer fixed between two anchor structures Scissors support system 3, the top scissors support system 3 includes one or more middle longitudinal beams 7, bottom beams 8, sliders 9 and two rows of scissors structures 10, the two rows of scissors structures 10 are symmetrically distributed on At the two ends of the middle longitudinal beam 7, the wire rope damper 2 is not directly connected to the anchor structure, but is installed between the two rows of scissor brace structures 10, and a plurality of scissor brace structures 10 are arranged at the top and side vertically. The beam 6 is connected to one end of the middle longitudinal beam 7, and the bottom of the scissor...

Embodiment 3

[0056] Such as Figure 11 As shown, when the beam body or building structure is relatively thick, that is, when the expansion joint depth is relatively deep, on the basis of Embodiment 2, a bottom scissors support system 15 can also be set, and the bottom scissors support system 15 is The direction is arranged below the top scissors support system 3, and one or more wire rope dampers are arranged in the bottom scissors support system 15, and the bottom scissors support system includes a slide block and two rows of scissors structures (not shown in the figure). Specifically shown), the slider and the two rows of scissor brace structures are the same as those in the top scissor brace support system, and the scissor brace structure of the bottom scissor brace support system and the scissor brace structure of the top scissor brace support system pass through the shared bottom beam It is connected with the slide block, and the bottoms of the adjacent scissor supports in each row of...

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. [0004] 1) Modular expansion joints [0005] Each load-bearing sliding member (beam, middle beam and support frame) of the modular expansion device...
