Fastener connecting structure for cantilever box beam triangle brackets

The invention provides a fastener connecting structure for cantilever box beam triangle brackets, and relates to the technical field of bridge construction. The fastener connecting structure comprises a pier, wherein triangle brackets are symmetrically arranged on the two sides of the pier; embedded parts are arranged in the pier; the triangle brackets are fixedly mounted on the side walls of the pier through the embedded parts; the triangle brackets symmetrically on the two sides of the pier are connected through an anchoring system; the embedded parts and the triangle brackets are connected through steel plate fastener pins; the triangle brackets on the same side of the pier are connected into a whole body through a transverse connecting system. The load is transferred by utilizing the steel plate fastener pins, so that the shear capacity is improved, and the influences that concrete is heated and fractured and steel plates are deformed caused by direct welding and thermal cutting on the embedded parts are completely eradicated.
