SPIRAL STAIRCASE
PROBLEM TO BE SOLVED: To provide a spiral staircase that is easy to construct because the number of types of components and the number of the components are small, and also is light-weight.SOLUTION: A spiral staircase includes steps, each of which has a center column insertion hole formed on an end on the staircase center side, the steps being spirally arranged around an erected center column. Each step has handrail column insertion holes formed on a stair-nosing and stair-tail parts on an end on the staircase outer side. A handrail column insertion hole formed on a stair-nosing part on an end on the staircase outer side of a step positioned on the upper side and a handrail column insertion hole formed on a stair-tail part on an end on the staircase outer side of a step positioned on the lower side are arranged so that the holes overlap with each other; the adjacent two steps are held and fastened using two nuts screwed on a handrail column that is inserted into the two overlapping handrail column insertion holes and is erected. As a step of the spiral staircase, a foam body composed of a synthetic resin skin and a foam core material, a step including a plate-like part and a rib part, etc. can be used.SELECTED DRAWING: Figure 2
【課題】部品の種類や点数が少なく、組立が容易な螺旋階段、さらには軽量な螺旋階段を提供する。【解決手段】階段中心側端部に心柱挿入用孔が形成された踏み板を、立設された心柱を中心に螺旋状に配列した螺旋階段であって、踏み板の階段外側端部の段鼻部と段尻部とに手摺柱挿入用孔が形成されており、上側に位置する踏み板の階段外側端部の段鼻部に形成された手摺柱挿入用孔と下側に位置する踏み板の階段外側端部の段尻部に形成された手摺柱挿入用孔とが重なるように配置され、２つの重なる手摺挿入用孔に挿入して立設した手摺柱に螺合する２つのナットにより隣接する２つの踏み板を挟んで締め付けられている。螺旋階段の踏み板には、合成樹脂製の外皮と発泡芯材とからなる発泡体や板状部とリブ部を備える踏み板等を使用することができる。【選択図】図２
