JOINT STRUCTURE OF JOINT AND ITS CONSTRUCTION METHOD

PROBLEM TO BE SOLVED: To provide a joint structure of a joint, which can enhance constructibility, and which can have sufficient durability by reducing a construction cost and preventing the appearance of a crack in a joint surface of a joint space section. SOLUTION: Two or more precast members, which are elongated toward the joint space section 6 forming the joint, are prestressed in the direction of the elongation of them; end plates 21 and 22 are arranged on the end surfaces of them; joint members 18 and 19, which are composed of a prefabricated fiber-reinforced concrete member, are arranged in the joint space section 6; iron plates 25, which are arranged on opposed surfaces, face the end plates 21 and 22 of the precast member, respectively; and the end plates 21 and 22 of the precast members and the iron plates 25 of the joint members are joined together by being welded to one another.
