REINFORCEMENT BAR HOLDER, REINFORCEMENT BAR LIFTING DEVICE USING THE SAME, AND INSTALLATION METHOD OF REINFORCEMENT BAR JOINT
To provide an innovative lifting technology not only capable of lifting a plurality of reinforcement bars in a vertical attitude with respect to a crane at an interval to each other in a horizontal direction but allowing reinforcement bar joint workers to detach the reinforcement from the crane while they stay at reinforcement bar joint work positions respectively.SOLUTION: A reinforcement bar lifting device 1 using reinforcement bar holders 3 comprises a balance 2 provided with a plurality of lifting parts 23, wherein an upper end of a fastening part 40 of a lifting cable 4 of which a lower end a holding device 5 capable of temporarily connected in a middle position of an objective reinforcement bar SB near a right top part of an installation length range L0 of reinforcement bar joints is arranged on a lifting part 22 from a lower end of the objective reinforcement bar SB, wherein at the middle of the lifting cable 4, a plurality of the reinforcement bar holders 3 provided with holding rings 6 in loose-fit near to an upper end of the objective reinforcement bar SB temporarily connected on the holding device 5 are lifting down to be positioned in generally balance positions from each of at least two positions of the lifting parts 23 on a balance frame 22 of the balance 2, which are separated apart from each other.SELECTED DRAWING: Figure 9
【課題】クレーンに対して複数本の鉄筋を水平方向に間隔を隔てて縦姿勢に吊り下げるのを可能とする上、鉄筋継手作業員が、鉄筋継手の作業位置に留まりながら、クレーンから鉄筋を離脱することができる新たな鉄筋吊上げ技術を提供する。【解決手段】複数の吊下部２３が設けられた天秤２を有し、吊下部２２に上端の繋着部４０が繋着された吊り索条４の下端に、対象鉄筋ＳＢの下端から、鉄筋継手施工長範囲Ｌ０の直上付近となる同対象鉄筋ＳＢの中途位置に仮結合可能なホールドバイス５が設けられ、吊り索条４の中途部に、ホールドバイス５に仮結合された対象鉄筋ＳＢの上端寄りに遊嵌する保持環６が設けられてなる鉄筋ホルダー３の複数本が、当該天秤２の天秤枠２２の互いに間隔を隔てた少なくとも二箇所の吊下部２３の夫々に、互いに略均衡する配置となるよう吊下された、鉄筋ホルダー３を利用した鉄筋吊上げ装置１である。【選択図】図９
