THREAD REINFORCING BAR SCREW ALLOY AND JOINT
To suppress rattling between the threaded reinforcing bar joint and the threaded reinforcing bar with a simple structure and improve the workability of joining between the joint and the threaded reinforcing bar.SOLUTION: A joint body 21 of a threaded reinforcing bar joint 20 is cylindrical and has openings 22 at both ends and a female threaded portion 23 on the inner circumference. The threaded reinforcing bar 10 is screwed from the opening 22 to the female threaded portion 23. The female threaded portion 23 has first regions 23a on both ends opening 22 side and a second region 23b between these first regions 23a. The first region 23a has a screw pitch corresponding to the threaded reinforcing bar 10, and the second region 23b has a pitch smaller than that of the first region 23a.SELECTED DRAWING: Figure 2
【課題】簡素な構造でねじ鉄筋用継手とねじ鉄筋のがたつきを抑え、継手とねじ鉄筋の接合の作業性を向上させる。【解決手段】ねじ鉄筋用継手２０の継手本体２１は、筒状で両端に開口２２を有し、内周に雌ねじ部２３を有する。開口２２から雌ねじ部２３にねじ鉄筋１０が螺合される。雌ねじ部２３は、両端開口２２側の第１の領域２３ａと、これらの第１の領域２３ａの間の第２の領域２３ｂを有する。第１の領域２３ａはねじ鉄筋１０に対応するねじピッチを有し、第２の領域２３ｂは第１の領域２３ａより小さいピッチを有する。【選択図】図２
