SAFETY TOOL FOR TEMPORARY SCAFFOLD
PROBLEM TO BE SOLVED: To provide a safety tool for a temporary scaffold capable of improving safety of the temporary scaffold by not only preventing a crossing brace or a lower crosspiece provided in the temporary scaffold from dropping-off but also preventing a ledger plate from being displaced to create a gap.SOLUTION: A safety tool for a temporary scaffold comprises: dropping-off preventing member for a crossing brace/a lower crosspiece including a fixing part fixed at an upper position than a crossing brace pin arranged on a vertical column of a scaffold frame, and a pair of extending arms arranged on both sides of the crossing brace pins, which extends downward from the fixing part, the dropping-off preventing member preventing an end of the crossing brace and/or the lower crosspiece from dropping-off from the crossing brace pins; and a displacement preventing member including an engaging claw drooped to an outer side of an engaging hook of a ledger plate placed at a lower end of the extending arm, and an abutting part protruded outward further than the engaging claw, of which a tip end is abutted to the vertical column of the scaffold frame, the displacement preventing member preventing the ledge plate from being displaced.SELECTED DRAWING: Figure 2
【課題】 仮設足場に設けられた交差筋交いや下桟が脱落するのを防止するとともに、布板がズレて隙間が発生するのを防止し、仮設足場の安全性を向上することができる仮設足場用安全具を提供する。【解決手段】 建枠の垂直支柱に設けられた交差筋交いピンよりも上方位置に固定される固定部と、固定部から下方に延出されて交差筋交いピンの左右両側に配置される一対の延出アームとを有し、交差筋交いおよび／または下桟の端部が交差筋交いピンから脱落するのを防止する筋交い・下桟脱落防止部材と、延出アームの下端部に設けられ布板の引掛フックの外側に垂下される係止爪と、係止爪よりも外側に延出され、その先端部が建枠の垂直支柱に当接する当接部とを有し、布板のズレを防止する布板ズレ防止部材と、を備える。【選択図】 図２
