REINFORCING MATERIAL PUSH-UP METHOD AND PUSH-UP FIXING DEVICE
To provide a method and device that can perform the operation of pushing up and fixing a reinforcing material in a hollow columnar body more easily than before.SOLUTION: A push-up fixing device 1 comprises: a fixed blade 10 having wings 12 and 13 extending obliquely downward from a central portion 11; a core rod 20 handing from the central portion 11 of the fixed blade; a reaction force generating member 30 loosely inserted into the core rod 20; a support nut 40 for applying an upward pressure to the reaction force generating member 30 by screwing with the core rod 20 to support and rotate the reaction force generating member 30 from below; a reinforcing material holding member 50 supported by the support nut 40 together with the reaction force generating member 30; and a push-up bar 60 contacting the support nut 40 from below and rotating the support nut 40 by rotating the core rod 20 as a rotation axis. A cylindrical reinforcing material is wound around an outer peripheral surface of the reinforcing material holding member 50 and held.SELECTED DRAWING: Figure 1
【課題】中空柱状物の中に補強材を押し上げて固定する作業を、従来よりも簡単に行える方法と装置を提供する。【解決手段】押上固定装置１は、中央部１１から斜め下向きに延出した翼部１２，１３を備えた固定刃１０と、固定刃の中央部１１から垂下する芯棒２０と、芯棒２０に緩挿された反力発生部材３０と、芯棒２０に螺合して反力発生部材３０を下から支持し且つ回転させることで反力発生部材３０に上向圧力を加える支持ナット４０と、反力発生部材３０と共に支持ナット４０で支持される補強材保持部材５０と、支持ナット４０に下から当接し且つ芯棒２０を回転軸として回転操作されることで支持ナット４０を回す押上棒６０とを有し、補強材保持部材５０に、筒状の補強材が外周面を巻き付けて保持される。【選択図】図１
