Description

Technical Field

[0001] The utility model relates to the technical field of rubber bearings, in particular to an assembled rubber bearing for a highway bridge. Background Art

[0002] Below the expansion joint of the highway bridge, the skateboard rubber bearings are located between the pier and the main beam, and they bear the vertical and horizontal loads imposed by the main beam. The skateboard rubber bearings are elastic-plastic bodies. Under the action of vertical loads, they will produce a compression of 1-6mm, causing the bridge deck to sag in the transverse direction of the bridge. Under the action of horizontal loads, shear deformation will occur. When the shear deformation is too large, the rubber on the side will crack, the steel plate will be exposed, and the use function will be lost. The service life of a highway bridge is generally 30-50 years, and the skateboard rubber bearings need to be replaced every 10 years on average. During the use of the bridge, the highway bridge assembled rubber bearings need to be used to replace the base;

[0003] Announcement No. CN201116363Y discloses a prefabricated rubber bearing for a highway bridge, which consists of three parts from top to bottom: a stainless steel frame, a stainless steel plate and a carbon steel plate. The skateboard-type rubber bearing is embedded in the stainless steel frame at the top of the steel member, and the carbon steel plate at the bottom of the steel member is welded to the structural steel bar at the top of the pier. When the prefabricated rubber bearing is installed, the inclination angle of the top surface of the skateboard-type rubber bearing is completely consistent with the inclination angle of the bottom surface of the main beam, and the main beam can be lifted at any time, and the front baffle of the stainless steel frame of the steel member can be opened to adjust the elevation of the top surface of the skateboard-type rubber bearing, or replace the skateboard-type rubber bearing;

[0004] There may be two problems when using it. First, in the process of assembling the rubber base on different bridges, the length of the baffle needs to be customized according to the length and width of the inner side of the different bridges, which makes the device difficult to popularize and use, thereby making the manufacturing cost of the device high; second, it is difficult for the device to assemble special-shaped rubber bases, which makes the scope of use narrow, and the rubber base can only be assembled in one direction, which makes the operation inconvenient; therefore, we proposed an assembled rubber bearing for highway bridges.
