SCAFFOLD BEAM FRAME AND OPENING STRUCTURE OF TEMPORARY SCAFFOLD

PROBLEM TO BE SOLVED: To reduce a vertical load borne by a scaffold.SOLUTION: A scaffold beam frame (a beam frame B) to be installed so as to bridge between scaffolds on both sides to provide an opening in a temporary scaffold, which comprises a connecting tool 11 connectable to an opening side strut A1 of a scaffold A on both ends of a horizontal member 10. A strut 20 includes at least an end strut 20a provided at a position slightly spaced rearward of the connecting tool 11, and the beam frame B is supported directly or indirectly by an auxiliary strut E attached thereto, with respect to the end strut 20a, so as to reduce the vertical load borne by each scaffold A.SELECTED DRAWING: Figure 1 【課題】足場が負担する鉛直荷重を軽減可能とすること。【解決手段】仮設足場に開口部を設けるために両側の足場間に架け渡すように設置する足場用梁枠（梁枠Ｂ）であって、水平材１０の両端には、足場Ａの開口部側支柱Ａ１と連結可能な連結具１１を備える。支柱２０は連結具１１の後方へと僅かに離隔した位置に設ける端支柱２０ａを少なくとも含んでおり、この端支柱２０ａに対し、直接又は間接的に補助支柱Ｅを取り付けて梁枠Ｂを支持することで、各足場Ａが負担する鉛直荷重の軽減を図る。【選択図】図１
