Claims

[Claims for Utility Model Registration] (1) A steel joint plate 2 is fixed across both ends of a pair of steel side plates 1 arranged parallel to each other with an interval between each side plate 1 and each joint plate 2. A steel skin plate 3 is fixed across the outer edge, and a plurality of joint fittings 4 are fixed to the inside of the joint plate 2 at intervals in the longitudinal direction of the joint plate. A space surrounded by the side plate 1, the joint plate 2, the skin plate 3, and the joint fittings 4, in which the anchor reinforcing bars 5 are fixed, is filled with reinforcing bars 6 and concrete 7. In the composite segment, in which a through hole 8 for connecting fittings is provided, a reinforcing bar dowel 9 is fixed by welding to the inside of the joint plate 2 between adjacent fittings 4 and between the side plate 1 and the fitting 4. Reinforcement structure of synthetic segment joints. (2) A skin plate 3 is installed inside the steel joint plate 2.
2. The reinforcing structure for a synthetic segment joint according to claim 1, wherein a large number of reinforcing bar dowels 10 are fixed by welding and are arranged at intervals in the longitudinal direction of the joint plate and pass between the joint metal fittings 4 and 4.
