Abstract
【解決手段】 階段枠7の側桁8下端に設ける脚体12は台座14両側部の台座側板15を側桁8に軸支する。台座14の一辺には立上り部19と固定金具20を設け、ホルダ21を回動可能に取り付ける。ホルダ21に遊挿する係止棒体22の直線端部には止金具22aを固着しコイルバネ22bを巻装する。係止棒体22の折曲部22cを足場布板5のスリット5cの方向と合わせ、挿入しながら押し下げ、下方で折曲部22cを回動する。コイルバネ22bの作用により折曲部22cは足場布板5下面に当接する。係止棒体22を足場布板5に係止することで吹き上がり防止等の対策を採ることができ、地震等の外部負荷があっても階段枠7の下部は滑らない。
