Description

Technical Field

[0001] The utility model relates to the technical field related to bridge bearings, and in particular to an integrated bridge bearing. Background Art

[0002] Bridges are generally composed of superstructures, substructures, bearings and auxiliary structures. Bridge bearings are important components that connect and constrain the upper and lower structures of bridges, and are an indispensable part of the load-bearing capacity of bridges.

[0003] After massive searches, it was found that the prior art publication number is CN220246662U, which discloses a bridge anti-falling beam structure, which includes a beam body, a support unit and a bridge pier from top to bottom. The support unit includes an upper support and a lower support from top to bottom. A spherical crown is provided between the bottom of the middle end of the upper support and the top of the middle end of the lower support below; U-shaped steel structures are provided at both ends of the support unit, and the U-shaped steel structure includes a connecting U-shaped plate and connecting straight plates located at the top and bottom ends of the connecting U-shaped plate. The connecting straight plates can be fixed on the beam body through the left and right ends of the upper support or can be fixed on the bridge pier through the left and right ends of the lower support. The bridge anti-falling beam structure of the utility model has a certain elastic buffer space through the connecting U-shaped plate between the two connecting straight plates of the U-shaped steel structure when an earthquake occurs, which can greatly reduce the probability of falling beams.

[0004] In summary, in the existing bridge bearings, the upper bearing and the lower bearing are connected together by an outer U-shaped steel structure, which can play the role of preventing the beam from falling, but the integrity of the upper bearing and the lower bearing is poor, so that the bearing will generate impact load during installation.

[0005] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create an integrated bridge bearing to make it more valuable for industrial use. Utility Model Content
