REINFORCEMENT HOLDING TOOL
To increase holding power of each reinforcement of a reinforcement holding tool which holds crossing two reinforcements.SOLUTION: A reinforcement holding tool comprises: two pressing plates 11, 12 disposed in a state where tip edges become near each other and a separation distance gradually increases as moving toward the other end edge; a plate spring portion 13 elastically urging each pressing plate so as to keep a closed position and allowing each tip edge to widen when applied with an opening power; and two locking members 21, 22 for locking a first reinforcement each of which is pivotally supported so as to rotate by pivotally supporting portions 15, 17 provided at positions near each tip of each pressing plate. A center portion of each tip edge of each pressing plate is provided with engagement recesses 14, 16 respectively capable of supporting a first reinforcement by engagement at the same time. In a nipping space SP between the first reinforcement RB1 supported by each engagement recess by engagement and each tip edge of each pressing plate, a second reinforcement RB2 can be engaged in a posture of crossing the first reinforcement while widening each pressing plate. In a state where the second reinforcement is supported by nipping in the nipping space, each locking member locks the first reinforcement.SELECTED DRAWING: Figure 1
【課題】交差する２本の鉄筋を保持する鉄筋保持具において、各鉄筋の保持力を高める。【解決手段】互いの先端縁を近接させ、且つ他端縁に向かう程に離間距離が漸増するように配置された２つの加圧板１１、１２と、各加圧板を、閉位置を維持するように弾性付勢し、且つ開放させる力が作用した時に各先端縁の拡開を許容する板バネ部１３と、各加圧板の各先端寄り位置に設けた軸支部１５、１７により夫々回動自在に軸支される第１鉄筋係止用の２つの係止部材２１、２２と、を備え、各加圧板の各先端縁中央部には、第１鉄筋を同時に嵌合支持可能な嵌合凹所１４、１６が夫々設けられ、各嵌合凹所により嵌合支持された第１鉄筋ＲＢ１と各加圧板の各先端縁との間の挟圧空間ＳＰ内には、第１鉄筋と交差した姿勢で、且つ各加圧板を拡開させながら第２鉄筋ＲＢ２が嵌合可能であり、挟圧空間内に第２鉄筋が挟圧保持された状態において、各係止部材は第１鉄筋を係止する。【選択図】図１
