Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a sheet installation method and a device capable of quickly realizing cargo unloading, sheet pulling-up and sheet fixing work of a pulled-up sheet by saving labor, even when tensioning a heavy sheet.SOLUTION: A guardrail 3 is used for a work sheet installation method, and the guide rail 3 installed in a horizontal attitude in a longitudinal backing material positioned in the uppermost layer and the lowest layer of a scaffold formed of a single pipe, is a cross-sectional substantially U shape, and is oppositely provided with an opening of a U-shaped groove in upper-lower layers of the scaffold, and comprises a connection socket 31 in one end part and a clamp 4 in its rear, on the one hand, forms connection parts 3b and 3c in the other end part, and a plurality of these guide rails 3 are connected in the width direction of the scaffold by successively fitting the connection parts 3b and 3c of the other guide rail 3 in the connection socket 31 of one guide rail 3, and the respective clamps 4 of the respective guide rails 3 are joined to the longitudinal backing member of the scaffold, and are thereby installed in the width direction of the uppermost layer and the lowest layer of the scaffold.SELECTED DRAWING: Figure 2
【課題】重量シートを張設する場合であっても、省力的かつ迅速に高い安全性の下で荷揚げやシート引上げ、並びに、引上げたシートのシート掛け作業を実現できるシート設置方法と装置を提供する。【解決手段】工事用シート設置方法に用いるガードレール3であって、単管等で形成された足場の最上層と最下層に位置する縦地部材に水平姿勢で架設される前記ガイドレール3は、断面略U状であって前記足場の上下層においてU状溝の開口を対向させて設けると共に、一端部に接続用ソケット31とその背後にクランプ4を備えている一方、他端部に接続部3b、3cを形成して成り、このガイドレール3の複数本を、一のガイドレール3の接続用ソケット31に他のガイドレール3の接続部3b、3cを順次嵌入して前記足場の幅方向に接続すると共に、各ガイドレール3の夫々のクランプ4を足場の縦地部材に結合することにより、前記足場の最上層と最下層の幅方向に架設する。【選択図】図2 |
