PROBLEM TO BE SOLVED: To provide a stair enabling strength and safety to be improved when used as a temporary stair.SOLUTION: A stair 1 comprises: a substrate tread board 3, which is fixed between a pair of lateral plates 2, 2 disposed substantially in parallel; a substrate riser 4, which is erected and fitted to a riser of the substrate tread board; a decorative tread board 5, which is laid over and fixed to a top face 3a of the substrate tread board; and a decorative riser 6, which is laid over and fixed to a front face 4a of the substrate riser. The substrate tread board has a cutout part 30, which is formed by cutting out a section from a front end face 3b to an undersurface 3c, and its rear end face 3d is fixed by a rear fixture 7b that penetrates the substrate riser from the rear face 4d of the substrate riser. The substrate riser is disposed so that its upper rear face 4da butts against a front end face 30b of the cutout part, and is fixed by a front fixture 7a that penetrates the substrate riser from front side of the substrate riser.SELECTED DRAWING: Figure 1
【課題】仮設階段として使用する際の強度及び安全性の向上を図ることができる階段を提供する。【解決手段】略平行に配置される一対の側板２，２間に固定される下地踏板３と、下地踏板の蹴込みに立設して取り付けられる下地蹴込板４と、下地踏板の上面３ａに重ね合わせて固定される化粧踏板５と、下地蹴込板の前面４ａに重ね合わせて固定される化粧蹴込板６とを備えた階段１であって、下地踏板は、その前端面３ｂから下面３ｃにかけて切欠き形成された切欠部３０を有し、その後端面３ｄは、下地蹴込板の後面４ｄから下地蹴込板を貫通する後方固定具７ｂにより固定されており、下地蹴込板は、その上方後面４ｄａが切欠部の前端面３０ｂに当接するように配され、その状態で下地蹴込板の前方から下地蹴込板を貫通する前方固定具７ａにより固定されていることを特徴とする。【選択図】図１
