TEMPORARY SCAFFOLDING OPERATION DEVICE
To provide a temporary scaffolding operation device that does not generate hammer noise or sparks when the connection strengthening member is operated with respect to the holder of the scaffolding support when the horizontal member is attached to and disassembled from the scaffolding support.SOLUTION: A temporary scaffolding operation device 10 includes a mounting portion 11 that is detachably mounted to the peripheral surface of the horizontal member and a supported member 16 that is swingably supported by the mounting portion 11 via an operation shaft 15. In the state where the mounting portion 11 is mounted on a horizontal member 100, and a groove portion 18 of the supported member 16 is fitted with a protruding piece 162 of a connection strengthening member 150, when the operation shaft 15 is swung via a ratchet wrench 40, it is possible to increase or decrease the amount of insertion into a connecting hole 212 provided in a holder 210 of a scaffolding support 200 of the connection strengthening member 150.SELECTED DRAWING: Figure 6
【課題】足場支柱に対して横架部材を取付及び解体する際、足場支柱のホルダに対する連結強化部材の操作時にハンマー音及び火花の発生がない仮設足場用操作装置を提供する。【解決手段】仮設足場用操作装置１０は、横架部材に対して着脱自在にその周面に取り付けられる取付部１１と、取付部１１に対して操作軸１５を介して揺動自在に支持された被支持部材１６とを有する。取付部１１が、横架部材１００に取り付けられ、かつ、被支持部材１６の溝部１８が連結強化部材１５０の突出片１６２と嵌合した状態で、ラチェットレンチ４０を介して操作軸１５を揺動操作すると、連結強化部材１５０の足場支柱２００のホルダ２１０に設けられた連結孔２１２に対する挿入量の増減が可能である。【選択図】図６
