PROBLEM TO BE SOLVED: To enable a beam main reinforcement to be quickly and definitely connected in an on-site connection work of precast concrete members.SOLUTION: A reinforcement joint coupler 10 comprises: a small diameter part 12 on which a female screw part capable of being screwed together with a joint reinforcement formed of screw-knotted reinforcement is formed; and a large diameter part 11, which has larger inner diameter than that of the female screw part and can be freely fitted with another joint reinforcement. On the large diameter part 11, a grout filling hole 14 is formed on a side near the small diameter part 12 and a grout discharge hole 15 is formed on the opposite side of the grout filling hole 14 across another joint reinforcement to be stored.SELECTED DRAWING: Figure 1
【課題】プレキャストコンクリート部材の現場接合作業において、梁主筋を迅速かつ確実に接合する。【解決手段】 鉄筋継手カプラー１０であって、ねじ節鉄筋からなる接合鉄筋と螺合可能な雌ねじ部分が形成された小径部１２と、雌ねじ部分の内径より大きな内径を有し、他の接合鉄筋を遊嵌可能な大径部１１とを備える。大径部１１は、小径部１２に近い側にグラウト充填孔１４が形成され、収容される他の接合鉄筋を挟んでグラウト充填孔１４の反対面にグラウト排出孔１５が形成されている。【選択図】 図１
