UNIT CONSTRUCTION OF SPIRAL STAIRCASE AND ASSEMBLY METHOD FOR SPIRAL STAIRCASE
To solve the problem in which, in a conventional helical staircase with a girder structure, mounting accuracy of stair treads is difficult to secure and assembly checking cannot be conducted in a factory in advance, leading to instable quality.SOLUTION: A unit construction of a helical staircase with a girder structure is constituted with multiple stair tread members comprising a horizontal member with a tread at its upper side and one or more vertical members coupling vertically below the horizontal member, and helical multiple lines of plates. The multiple lines of plates are fixed to face side end faces of the vertical members and lower sides of the horizontal members respectively of the stair tread members after helically placing the stair tread members with temporary support materials and then constitute a helix by detaching the temporary support materials.SELECTED DRAWING: Figure 11
【課題】従来から存在する桁構造の螺旋階段は、段板取り付けの精度確保が難しく、事前に工場で組立検査を行うこともできず、品質が安定しない。【解決手段】桁構造の螺旋階段のユニット構造として、上側に踏み面を有する水平部材と当該水平部材の下方へ垂直に接続する１または複数の鉛直部材とから成る複数の段板部材と、螺旋の複数列の板材とから構成され、複数列の板材は、仮支柱材にて段板部材を螺旋に設置後に、段板部材の鉛直部材の側端面及び水平部材の下辺に面して固定することで、仮支柱材を離脱させて螺旋を構成する。【選択図】図１１
