Description

Technical Field

[0001] The utility model relates to the technical field of bridge bearings, in particular to a bridge bearing which is easy to install. Background Art

[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. The superstructure, also known as the bridge span structure, is the main structure for crossing obstacles; the substructure includes abutments, piers, and foundations; the support is a force transmission device installed at the supporting location between the bridge span structure and the piers or abutments. The bridge support is an important structural component connecting the superstructure and substructure of the bridge. It can reliably transmit the reaction force and deformation (displacement and rotation) of the bridge superstructure to the bridge substructure. It is a device erected on the piers and supports the superstructure of the bridge on the top surface. Its function is to fix the superstructure to the piers, withstand various forces acting on the superstructure, and reliably transmit them to the piers.

[0003] For example, Chinese patent publication No. CN214613566U discloses a bridge bearing that is easy to install, including a base, a fixed plate, an upper support seat and a lower support seat, the lower support seat is fixedly installed in the middle of the top of the base, the second buffer plate is fixedly installed at the bottom end inside the lower support seat, the top of the second buffer plate is fixedly installed with a shock-absorbing plate, the bottom end inside the shock-absorbing plate is fixedly installed with a plurality of shock absorbers, the top of the shock-absorbing plate is fixedly installed with a pressure plate, the top of the pressure plate is fixedly connected to the bottom end of the fixed steel plate, the top of the fixed steel plate is fixedly installed with a first buffer plate, the first buffer plate, the top of the first buffer plate is placed with a sealing plate, and the top of the sealing plate is fixedly connected to the top inside the upper support seat.

[0004] However, in the above solution, when the rubber pressure plate needs to be replaced due to aging or other reasons, it is inconvenient to disassemble and replace the rubber pressure plate, so the entire support needs to be replaced, which increases the replacement cost and is not very convenient.

A rubber column is placed in the lower limiting ring, and the two ends of the rubber column are respectively against the side walls of the two fixing plates. A supporting device is provided on the top side wall of the lower fixing plate, and four positioning columns are fixedly connected to the bottom side wall of the lower fixing plate.
