Description

Technical Field

[0001] The utility model relates to the technical field of bridge bearings, in particular to a shock-absorbing bridge bearing. Background Art

[0002] A bridge bearing is an important structural component connecting the upper and lower structures of a bridge. It is located between the bridge and the cushion stone. It can reliably transfer the loads and deformations (displacements and rotations) borne by the upper structure of the bridge to the lower structure of the bridge. It is an important force transmission device for bridges. There are two types of fixed bearings and movable bearings. The commonly used bearing forms in bridge engineering include: felt or flat bearings, plate rubber bearings, spherical bearings, steel bearings, and special bearings, etc. The existing bridge bearings have a simple structure and poor stability of the shock-absorbing structure, making the bridge prone to collapse under severe external forces.

[0003] In the prior art, an anti-seismic bridge bearing with multi-stage shock absorption, with the application number 202110018712.6, includes an upper bearing, a lower bearing, and a plurality of support columns. The support columns are symmetrically and fixedly installed on the upper bearing, and one end of the support column is slidably inserted into the lower bearing. A plurality of groups of primary buffer mechanisms are symmetrically arranged between the upper bearing and the lower bearing. The primary buffer mechanism includes a first buffer rod, a second buffer rod, a first slider, and a second slider. A middle column is arranged at the middle position of the lower bearing. The first slider and the second slider are respectively slidably installed on the lower bearing and the middle column. One end of the first buffer rod and the second buffer rod are jointly hinged on the upper bearing; this invention effectively protects the bridge through multi-stage shock absorption and avoids the phenomenon of collapse. However, the stability of the shock-absorbing structure is relatively general, thus affecting the shock-absorbing effect, and it is not suitable for use in situations where shock absorption is not required.
