    SPIRAL STAIRS AND METHOD FOR MANUFACTURING SPIRAL STAIRS

    New search for: KURIYAMA NORIHIRO

    PROBLEM TO BE SOLVED: To provide block type spiral stairs capable of improving a strength of a tread, and to provide a method for manufacturing the spiral stairs.SOLUTION: Spiral stairs 10 have a plurality of spirally fixed treads 100. Each of the treads 100 is composed of a plurality of swan plates 110 and 120. The swan plates 110 and 120 are bonded to each other so that the fibers are orthogonal to each other.SELECTED DRAWING: Figure 1

    【課題】 踏み板の強度を向上させることのできる積み木型の螺旋階段及び螺旋階段の製造方法を提供する。【解決手段】 螺旋階段１０は、螺旋状に固定された複数の踏み板１００を有する。各踏み板１００は、複数のひき板１１０、１２０によって構成される。ひき板１１０、１２０はその繊維が直交する態様で張り合わされている。【選択図】図１
