VERTICAL STRING MATERIAL FOR SPIRAL STAIRWAY, AND CONSTRUCTION METHOD OF SPIRAL STAIRWAY
To provide a construction method of a spiral stairway capable of constructing with only a wholly precut material in construction of a spiral stairway and constructing a spiral stairway in a short period of time extremely efficiently, and to provide a vertical string material used in the method.SOLUTION: A vertical string material for a spiral stairway has a vertically long shape, is formed to have an L-shape in a planar shape, and is constituted of a downstairs side portion 13 extending from an external corner portion 11 and an internal corner portion 12 toward downstairs side, and an upstairs side portion 14 extending toward an upstairs side. On an outside surface of the downstairs side portion 13, a first cutout groove 13a capable of making an inside end portion of a middle stage spiral step plate enter from the external corner portion 11 side to a direction of a downstairs side end edge 15 and supporting is formed. On an outside surface of the upstairs side portion 14, a second cutout groove 14a capable of making an inside end portion of an upper stage spiral step plate enter from an upstairs side end edge 16 side to a direction of the external corner portion 11 and supporting is formed at a position of a height which is higher than the first cutout groove 13a of the downstairs side portion 13 by one step of a stairway.SELECTED DRAWING: Figure 1
【課題】廻り階段の施工に際し、完全プレカット材のみによって施工することができ、極めて効率よく、短時間で廻り階段を施工することができる廻り階段の施工方法、及び、その方法に用いられる縦ささら材を提供する。【解決手段】縦長形状であって、平面形状がＬ字型となるように形成され、出隅部１１及び入隅部１２から階下側へ向かって延在する階下側部１３と、階上側へ向かって延在する階上側部１４とによって構成され、階下側部１３の外側表面に、中段の廻り段板の内側端部を出隅部１１側から階下側端縁１５の方向へ進入させて支持できる第一切欠溝１３ａが形成され、階上側部１４の外側表面に、上段の廻り段板の内側端部を階上側端縁１６側から出隅部１１の方向へ進入させて支持することができる第二切欠溝１４ａが、階下側部１３の第一切欠溝１３ａから階段一段分上方の高さの位置に形成されている。【選択図】図１
