PROBLEM TO BE SOLVED: To provide a joint which enables the mutual connection of both reinforcements already fixed to concrete etc., and can obtain the advantages of excellent construction properties of a screw-type reinforced joint and a shortened construction period. SOLUTION: A joint component set 2 for connecting male screws 1a and 1a formed at the opposed ends of the pair of reinforcements 1 and 1 is provided. The joint component set 2 comprises a pair of end-side screw cylinders 3 which are partially screwed to the male screw 1a of the reinforcement 1, an intermediate screw cylinder 4, and a pair of male screw components 5 and 5A which have both ends screwed to each of the end-side screw cylinder 3 and the intermediate screw cylinder 4. In the intermediate screw cylinder 4, a female screw 4a on one end side and a female screw 4b on the other end side are inversely threaded. Additionally, leads of both the female screws 4a and 4b and a lead of a female screw 3a of the end-side screw cylinder 3 are set different from each other. COPYRIGHT: (C)2011,JPO&INPIT
