[0002] As transportation hubs, bridges must withstand vehicle loads, natural erosion, and their own weight over long periods. As their service life increases, they are prone to defects such as beam cracking and bearing aging, directly threatening traffic safety. The supporting structure is the core of a bridge's load-bearing capacity, and its stability determines the overall load-bearing capacity. To slow down the development of defects and extend the life of bridges, support reinforcement devices have emerged. These devices address the weakness of the supporting structure by strengthening the support nodes and dispersing load stress, thus becoming key equipment for ensuring structural safety in bridge maintenance.

[0003] However, existing reinforcement devices are not convenient to install on bridges, requiring workers to spend a lot of time on their installation, and the operation is complicated, which greatly reduces the efficiency of bridge reinforcement device installation. Utility Model Content
