External prestress bearing device for reinforcing old bridge body

The utility model discloses an external prestress bearing device for reinforcing an old bridge body, which relates to the technical field of bridge engineering and comprises a bridge main body, a support is fixedly connected to the bottom of the bridge main body, a bridge pier is fixedly connected to the bottom of the support, and a bridge foundation is fixedly connected to the bottom of the bridge pier. A clamping plate is fixedly connected to one side of the bridge body, and a first splicing plate is fixedly connected to one side of the clamping plate. According to the external prestress bearing device for reinforcing the old bridge body, through the cooperative arrangement of the bridge main body, the clamping plates, the first splicing plates, the threaded holes and the second splicingplates, the left-right tension deformation of the bridge can be effectively prevented, and the problem that the left-right tension deformation of the bridge cannot be prevented at the same time in the prior art is solved; th
