Description

Technical Field

[0001] The utility model relates to the technical field related to bridge bearings, in particular to a hook-connection structure type bridge spherical 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, the upper and lower supports in the existing bridge supports are connected together by an outer U-shaped steel structure, which can prevent the beam from falling. However, the integrity of the upper and lower supports is poor, which makes the tensile strength of the supports relatively general.

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

[0011] As a further improvement of the utility model, an upper support convex block protruding downward is arranged in the middle of the bottom of the upper support, and the upper friction pair is installed on the upper support convex block.

[0012] As a further improvement of the utility model, the upper friction pair is a plane friction pair, and the lower friction pair is a spherical friction pair.

[0013] As a further improvement of the present invention, an elastic connecting piece is further connected between the upper connecting hook and the lower connecting hook.
