To provide a handrail frame for a stair opening capable of enhancing safety in a simple configuration while preventing a field worker walking on a scaffold from falling down.SOLUTION: A handrail frame 1 for a stair opening of the present invention is used for a prefabricated scaffold in which a plurality of building frames 4 is erected, and is installed around an opening 3 formed by hooking a temporary scaffold stair 2 on a connecting horizontal member 7 of any building frame 4. A first frame member 21, which has a cloth material 15 and a body part 16 formed into a frame shape by multiple frame members and is provided on the opposite side of a hatchway of the temporary scaffold stair 2, is provided with a gable side handrail material 26 extending in the horizontal direction and connected to a leg post 6 of the erection frame 4. A gable side middle rail 40 extending in the horizontal direction from the first frame member 21 and connected to the leg post 6 of the erection frame 4 is provided below the gable side handrail material 26. The gable side middle rail 40 is formed into a substantially L shape with a bent part curved along the periphery of the opening 3.SELECTED DRAWING: Figure 1
【課題】現場作業者が足場上を歩行する際に下方へ墜落することがなく、容易な構成で安全性を高めることのできる階段開口部用手摺枠を提供する。【解決手段】本発明の階段開口部用手摺枠１は、複数の建枠４が立設される枠組足場に用いられ、いずれかの建枠４の連結水平材７に仮設足場用階段２が掛止され、これによって生じる開口部３の周囲に設置されものであって、布地材１５と、複数の枠部材によって枠状に形成される本体部１６とを有し、仮設足場用階段２の昇降口とは反対側に設けられた第１枠部材２１には、水平方向に延び建枠４の脚柱６に連結される妻側手摺材２６が設けられ、妻側手摺材２６の下方に、第１枠部材２１から水平方向に延び建枠４の脚柱６に連結される妻側中さん４０が設けられ、妻側中さん４０は、開口部３の周囲に沿って、屈曲部分が湾曲した略Ｌ字状に形成されている。【選択図】図１
