Abstract: PURPOSE: A pressed-type end-bracket for reinforcing external wires of a girder is provided to enhance the load carrying capacity of the end-bracket, and reduce the size and weight of the end-bracket. CONSTITUTION: External wires(3) installed in a girder(5) enhance the load carrying capacity of a concrete structure such as a bridge or a building. An end-bracket comprises an end plate-member(32) and a reinforcing member. The end plate-member is put on the end side of the girder. The external wires are fixed in both ends, and supported by an anchorage(7). The reinforcing member consists of an anchor plate(34) and a triangular gusset-plate(30). One side of the anchor plate is united with the end plate-member, and the other side is united with the side of the girder. The gusset plate connects and supports the anchor plates. When a force is given to the anchorage by the tensile force of the wires, the end plate-member generates the compressive force to the gusset plate, and then the compressive force is given to the anchor plate. Therefore, the tensile force is converted into the compressive force, so that the load carrying capacity of the bracket is improved.
