PROBLEM TO BE SOLVED: To provide a preceding handrail that may be fitted to and removed from a support post readily and safely, when constructing and dismantling a temporary scaffold.SOLUTION: A preceding handrail 1 is installed between adjacent support posts P prior to forming a work floor B when constructing a temporary scaffold, and includes a handrail body 2, an engaging part 3 provided respectively on both ends of the handrail body 2 and engaged to a socket S provided on a peripheral wall of the support post P, and a pair of braces 4 held rotatably on each engaging part 3 through a first pivot q1 and capable of connecting a free end to the support post P below the engaging part 3 while intersecting with each other. The engaging part 3 of the preceding handrail 1 is held rotatably on the handrail body 2 through a second pivot q2.SELECTED DRAWING: Figure 1
【課題】仮設足場の構築及びその解体に際して、支柱への取り付け及び取り外しを簡便かつ安全に行うことができる先行手すりを提案する。【解決手段】仮設足場を構築する際、作業床Ｂの形成に先立って隣接支柱Ｐの相互間に設置される先行手すり１であって、手すり本体２と、手すり本体２の両端にそれぞれ設けられ、支柱Ｐの周壁に設けられたソケットＳに係止される係止部３と、係止部３にそれぞれ第１の枢軸ｑ１を介して回動可能に保持され、相互の交差姿勢でもって自由端を係止部３の下方でＰ支柱にそれぞれ連結可能な一対のブレース４と、を備え、係止部３は、第２の枢軸ｑ２を介して回動可能に手すり本体２に保持されている先行手すり１である。【選択図】図１
