Damping support with matching structure for bridge design

Abstract

The invention provides a damping support with matching structures for bridge design, relates to the technical field of bridge damping, and solves the problem that the damping effect is reduced due to the fact that a plurality of damping structures cannot be matched with one another, elastic looseness prevention of the fixing bolt cannot be achieved through structural improvement, and abutting skid resistance between the fixing base and the bridge rod cannot be achieved. The damping support with a matching structure for bridge design comprises a base, a buffer structure is installed on the base, four auxiliary structures are further installed on the base, and a bridge frame is fixedly connected to the base. A rotating seat is welded on a sliding seat, the rotating seat is rotatably connected with the gear, and the gear is meshed with a tooth row A; a baffle ring is connected to the sliding rod A in a sliding mode, a tooth row B is welded to the baffle ring and engaged with the gear, the tooth row A, the rotating base and the gear jointly form a reverse moving structure of the baffle ring and the tooth row B, and therefore secondary buffering of the top plate is achieved.

Description

technical field [0001] The invention belongs to the technical field of bridge damping, and more specifically relates to a damping support for bridge design with a matching structure. Background technique [0002] The bridge damping bearing is an important structural component connecting the bridge superstructure and the bridge substructure. Its function is to reliably transfer the load and deformation of the bridge superstructure to the bridge substructure to ensure the stability of the bridge. [0003] For example, the application number: CN201920934823.X relates to bridge damping bearings, specifically a multi-stage damping bearing for bridge design. The utility model solves the problems of poor damping effect and inconvenient installation and adjustment of traditional bridge damping bearings. A multi-stage damping support for bridge design, comprising an upper rectangular pressure plate, a lower rectangular pressure plate, an upper cylindrical buffer block, a lower cylin...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a bridge design damping support with a matching structure to solve the existing problem that although the existing device can realize the damping of the shock absorber through multiple damping structures shock effect, but its multiple shock-absorbing structures cannot cooperate with each other, which leads to the phenomenon that the shock-absorbing effect is reduced; moreover, the shock-absorbing seat and the bridge rod of the existing device cannot pass through the structural gap when they are fixed. Improve the elastic anti-loosening of the fixing bolts, and cannot realize the tightness and anti-slip between the fixing seat and the bridge rod
