Description

Bridge support with damping support structure Technical Field The utility model relates to the technical field related to bridge supports, in particular to a bridge support with a damping support structure. Background Bridges are generally composed of superstructure, substructure, supports and appurtenant structures. Bridge supports are important members for connecting and restraining the upper and lower structures of a bridge, and are an indispensable part for bearing the bridge. Through searching, found that the Chinese patent publication number is CN220246662U, a bridge anti-falling beam structure is disclosed, the bridge anti-falling beam structure sequentially comprises a beam body, a support unit and a bridge pier from top to bottom, the support unit sequentially comprises an upper support and a lower support from top to bottom, spherical crowns are arranged between the bottom of the middle end of the upper support and the middle top of the lower support below the upper support, U-shaped steel structural members are arranged at the left end and the right end of the support unit, each U-shaped steel structural member comprises a connecting U-shaped plate and connecting straight plates positioned at the two ends of the top and the bottom of the connecting U-shaped plate, and the connecting straight plates can be fixed on the beam body through the left end and the right end of the upper support or can be fixed on the bridge pier through the left end and the right end of the lower support.
