Vibration isolation buffer for bridge

Abstract

The invention discloses a vibration isolation buffer for a bridge, relates to the technical field of bridge engineering, solves problems of limited buffer capacity, poor anti-seismic effect on horizontal vibration and incapability of meeting actual requirements due to the fact that an existing bridge support generally buffers vibration in the vertical direction of the bridge through an elastic material in use. The vibration isolation buffer comprises a bridge base supporting plate. A group of left bridge deck mounting plates are mounted on the left side of the top of the bridge base supportingplate; a group of right bridge deck mounting plates are mounted on the right side of the top of the bridge base supporting plate; and two sets of damping buffers are hinged between the bridge base supporting plate and the right bridge deck mounting plates front and back. Hard damage caused by vibration can be prevented, and bridge components are better protected; meanwhile, buffering and vibration isolation between the left bridge deck mounting plate and the right bridge deck mounting plate in the horizontal direction can be achieved, buffering and vibration isolation between the right bridgedeck mounting plate and the bridge base supporting plate and between the left bridge deck mounting plate and the bridge base supporting plate are achieved, the buffering effect is good, and better vibration absorption performance is achieved.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a vibration isolation buffer for bridges. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. Bridges are generally composed of superstructures, substructures, supports and auxiliary structures. Structure, the substructure includes abutment, pier and foundation, and the support is the force transmission device set at the supporting place between the bridge span structure and the pier or abutment. [0003] For example, application number: CN201210501063.6 The present invention relates to a bridge support, including: a first support plate connected to the bridge beam body and a second support plate connected to the pier, wherein the first support plate and the second support plate The two bearing plates are fastened to each other and can slide relative to each other.

Problems solved by technology

[0005] The purpose of the present invention is to provide a vibration isolation buffer for bridges to solve the problem that the existing bridge bearings proposed in the above-mentioned background technology usually buffer the vibration of the bridge up and down through elastic materials during use, and the actual bridge will also Due to the vibration in the horizontal direction, the cushioning capacity is limited. At the same time, the existing bridge bearings have poor anti-seismic effect on horizontal vibration and cannot meet the actual needs.
