PRECEDING HANDRAIL
To provide a preceding handrail reduced in delivery burden by multiple workers in construction and removal to/from columns of a temporary scaffolding, to thereby allow further efficient work.SOLUTION: A preceding handrail 3 has a laterally extended handrail material 4, right and left two upper fixtures 5 installed at right and left ends of the handrail material 4 and having suspended insertion parts 51 inserted into socket metal fittings 21 of adjacent columns 2 and engaged, two diagonal materials 6 with base end parts rotatably connected to each of the upper fixtures 5, and two lower fixtures 7 installed at tips of the diagonal materials 6 and detachably attached to the columns 2 so as to construct both diagonal materials 6 to cross each other between both columns 2. To the upper fixture 5, a hooking part (slit part) 52A hooked to an arbitrary socket metal fitting 21 of the column 2 is installed in such a way that the preceding handrail 3 with both diagonal materials 6 folded to roughly follow the handrail 4 can be temporarily suspendedly hooked to one of the columns 2.SELECTED DRAWING: Figure 6
【課題】仮設足場の支柱間への架設および取り外しに際して、複数の作業者による受け渡しの負担を軽減して、より効率的に作業を行うことができる先行手摺を提供する。【解決手段】先行手摺3は、左右方向にのびる手摺材4と、手摺材4の左右各端部に設けられ隣り合う支柱2のソケット金具21に挿入されて係り止められる垂下状のインサート部51を有する左右２つの上部固定金具5と、基端部が各上部固定金具5に回動自在に連結されている２本の斜材6と、各斜材6の先端部に設けられ両斜材6が両支柱2間に互いに交差して架設されるように各支柱2に着脱自在に取り付けられる２つの下部固定金具7とを備えている。上部固定金具5に、両斜材6が手摺材4にほぼ沿うように折り畳まれた状態の先行手摺3を一方の支柱2に垂下状に仮掛けしうるように、同支柱2の任意のソケット金具21に掛け止められる掛止部（スリット部）52Aが設けられている。【選択図】図６
