PROBLEM TO BE SOLVED: To provide a prefabricated stair case capable of making a construction period shorter as well as preventing construction cost-up.SOLUTION: A prefabricated stair case 30, where each of a plurality of step members 8 including a tread board 4 arranged horizontally and a riser board 6 arranged perpendicular to a tread surface 4a of the tread board 4 is arranged in a shape of a stair along an inclined line, and the step members 8 of each of steps being fixed on a rod-like member 18 arranged toward in the inclined direction on an inclined surface 7, comprises: a plurality of support rods 20 erected at a longitudinal end side of the step member 8 by connecting a plurality of handrail support members 31 attached each of a plurality of rod-like members 18 to each of longitudinal lower ends of the support rods at each of the plurality of the handrail support members 31; and the plurality of rod-like handrail members 21 of which each of both longitudinal ends of the rod-like handrail members is attached at each longitudinal upper end of the plurality of the support rods 20, wherein each of the handrail support members 31 is removably connected with each of the plurality of the longitudinal lower ends of the support rods 20.SELECTED DRAWING: Figure 1
【課題】施工コストの高額化を防止すると共に、施工期間を短くすることができるプレハブ式階段を提供する。【解決手段】水平に配置される踏み板４と、この踏み板４の踏み面４ａに対して垂直に配置される蹴上げ板６とを有する複数のステップ部材８が、傾斜方向に沿って階段状に並べて配置され、各段のステップ部材８が、傾斜面７上の傾斜方向に配置された棒状部材１８の上に階段状に並べて固定されたプレハブ式階段３０において、棒状部材１８に取付けられた複数の手摺支持部材３１と、長さ方向下端部が手摺支持部材３１に連結されることにより、ステップ部材８の長さ方向端部側の位置に立設された複数の支柱２０と、複数の支柱２０の長さ方向上端部に、長さ方向両端部がそれぞれ連結された複数の棒状の手摺部材２１とを備え、手摺支持部材３１は、支柱２０の長さ方向下端部に着脱自在に連結されている。【選択図】図１
