Shear connector for steel-concrete composite beam bridge

The utility model relates to a shear connector for a steel-concrete composite beam bridge. The shear connector comprises at least three truss ribs, at least three steel plates and at least one steel bar group, the truss ribs are arranged side by side, the bottoms of the truss ribs are fixedly connected with an upper flange plate of the steel beam, and the length direction of the truss ribs is consistent with that of the steel beam. And the steel plates are in one-to-one correspondence with the truss ribs and are fixedly connected to the tops of the truss ribs. The steel bar set comprises a plurality of bent steel bars which are arranged at intervals in the length direction of the steel beam, the bent steel bars are perpendicular to the truss ribs, and the bottoms of the bent steel bars are fixedly connected with an upper flange plate of the steel beam. Every three adjacent truss ribs correspond to one reinforcing steel bar set, and the steel plate corresponding to the truss rib located in the middle is fixedl
