JOINT STRUCTURE OF REINFORCEMENT AND METHOD FOR REINFORCING BRIDGE PIER

PROBLEM TO BE SOLVED: To provide a joint structure of reinforcements which is embedded in a concrete member, and a method for reinforcing a bridge pier using the joint structure.SOLUTION: Precast forms 11a, 11b, each of which is divided into a plurality of parts, are arranged along the outer peripheral surface of a bridge pier skeleton 3. A reinforcement 13, which is bent in a U-shape so that its tip faces the other end side, is projected from the end surface of the precast form. An enlarged part 15, which projects outside from the peripheral surface of the reinforcement 13 to transmit a tensile force of the reinforcement 13 to concrete in which the reinforcement 13 is embedded, is formed on the tip of the reinforcement 13 The precast forms arranged along the outer peripheral surface of the skeleton 3 are installed with a space from the outer peripheral surface of the skeleton 3 and arranged with a space between adjacent precast forms. Between the adjacent precast forms, reinforcements 13a, 13b bent in a U-shape are projected from their precast forms and arranged so as to overlap with each other, and the surfaces of the enlarged parts 15 connected to the reinforcements 13a, 13b face each other.
