PROBLEM TO BE SOLVED: To provide a corrugated plate fixture that allows a corrugated plate placed on a structural member to be fixed below the corrugated plate by a worker, so as to prevent a serious injury or a death that could accompany a corrugated plate installation work in which a nut is tightened above the corrugated plate at a high place, usually performed in a short period without erecting a costly scaffold.SOLUTION: A corrugated plate fixture has a bolt driving part installed at a lower part of a bolt, as bolt rotation means having a screwing structure to be screwed in the direction of rotation, so as to allow the corrugated plate to be fixed on a structural member by working below the corrugated plate, by rotating the bolt driving part instead of a bolt head.
【課題】波板上でナット締めをする波板設置作業は高所作業のため大変危険である。水平に広がる波板設置は短期作業のため経費がかかる足場を作る事もない。波板の上でナット締めをする波板設置作業の最後の一枚の設置作業は特別に困難で最も危険を伴うな作業であるため大ケガや死が頭をよぎる。そこで構造材上に置かれた波板を施工者が波板の下で固定可能とすることを課題とする。【解決手段】ボルト下部にボルトを回転させる手段としてその回転方向に係合する係合構造したボルトドライブ部を設け、ボルト頭部でなくボルトドライブ部を回転させることで波板を波板の下で構造材に固定可能とした波板固定具。【選択図】 図５
