IRREGULAR SHAPE REINFORCEMENT JOINT METAL FITTING AND IRREGULAR SHAPE REINFORCEMENT CONNECTION METHOD
To surely and strongly join irregular shape reinforcements together even when the opposing irregular shape reinforcements are misaligned from each other in center axes with a small number of components.SOLUTION: A joint metal fitting 2 comprises: a one-side cylindrical locking member 21 having an inner screw 21a formed to be engaged with a screw 1a of a one-side reinforcement 1A on an inner peripheral surface and an outer screw 21b formed on an outer peripheral surface; the other-side cylindrical locking member 22 having an inner screw 22a formed to be engaged with a screw 1b of the other-side reinforcement 1B on an inner peripheral surface and an outer screw 22b formed on an outer peripheral surface; and a cylindrical connection member 23 having a connection screw 23a formed to be engaged with the outer screws 21b, 22b of the locking members 21, 22 on an inner peripheral surface. When seen from the extending direction of the reinforcements 1A, 1B, one or both of the positions of the inner screws 21a, 22a of the locking members 21, 22 are shifted from the center position of the connection member 23.SELECTED DRAWING: Figure 1
【課題】少ない部品数で、対向する異形鉄筋の中心軸がずれている場合でも、異形鉄筋同士を、確実に、かつ、強固に接合する。【解決手段】継手金具２を、内周面に一方側鉄筋１Ａのネジ部１ａと螺合される内ネジ部２１ａが形成され、外周面に外ネジ部２１ｂが形成された円筒状の一方側係止部材２１と、内周面に他方側鉄筋１Ｂのネジ部１ｂと螺合される内ネジ部２２ａが形成され、外周面に外ネジ部２２ｂが形成された円筒状の他方側係止部材２２と、内周面に一方側及び他方側係止部材２１，２２の外ネジ部２１ｂ，２２ｂと螺合する連結用ネジ部２３ａが形成された円筒状の接続部材２３とを備え、一方側鉄筋１Ａ及び他方側鉄筋１Ｂの延長方向から見たときの、一方側係止部材２１の内ネジ部２１ａの位置、及び、他方側係止部材２２の内ネジ部２２ａの位置のいずれか一方または両方が、接続部材２３の中心位置からずれている構成とした。【選択図】図１
