PROBLEM TO BE SOLVED: To provide a clamp for temporary work convenient when assembling a concrete form and assembling a temporary scaffold by using an electric screwdriver.SOLUTION: A clamp for temporary work is composed of a clamp body 1 out-fitted to an overlapping place of two members P1 and P2 and a fastening bolt 2 for threadedly engaging with/penetrating through this clamp body 1, and holds-joins the overlapping place of the two members P1 and P2 between a member receiving part 6 of the clamp body 1 and the inner end of the fastening bolt 2, and is constituted so that the outer end of the fastening bolt 2 is provided with a hexagon head part 12 and a projection plate part 13 projected in a concentric shape on the outside of this hexagon head part 12, and the projection plate part 13 is formed in a band plate shape of having a width of a size stored in the contour of the hexagon head part 12 when viewing the fastening bolt 2 from the axial direction and a plate thickness smaller than the width.
【課題】コンクリート型枠の組立てや仮設足場の組立てを、電動ドライバーを利用して行う場合に便利な仮設工事用クランプを提供する。【解決手段】２つの部材Ｐ１，Ｐ２の重なり箇所に対して外嵌するクランプ本体１と、このクランプ本体１を螺合貫通する締結用ボルト２とから成り、当該締結用ボルト２の締め付けにより、前記クランプ本体１の部材受け部６と前記締結用ボルト２の内端との間で、前記２つの部材Ｐ１，Ｐ２の重なり箇所を挟持結合する仮設工事用クランプにおいて、前記締結用ボルト２の外端には、六角頭部１２と、この六角頭部１２の外側で同心状に突設された突出板部１３とが設けられ、前記突出板部１３は、前記締結用ボルト２を軸心方向から見たときに前記六角頭部１２の輪郭内に収まるサイズの巾と、当該巾よりも小さい板厚を有する帯板状に形成された構成。【選択図】図２
