PROBLEM TO BE SOLVED: To provide a high sound insulation staircase capable of suppressing generations of noises in use to the utmost and effectively blocking transmission of vibrations to the outside of a stairhall.SOLUTION: A high sound insulation staircase includes a spiral step part that has an outside end of a spiral tread supported by two spiral side plates 13 and 14 joined in an L-shape, and a straight part that has both ends of a rectangular tread supported by two straight side plates 15 and 16 arranged in parallel, respectively. A self-supporting frame 1, which is not brought into contact with an interior wall of a stairhall, is formed on a floor surface on a downstairs side. The spiral side plates 13 and 14 and the spiral tread are supported on the self-supporting frame 1 independently of the interior wall in a position at a distance from the interior wall of the stairhall, and upper ends of the straight side plates 15 and 16 are supported on the self-supporting frame 1.SELECTED DRAWING: Figure 5
【課題】使用時における騒音の発生を可及的に抑制するとともに、階段室外への振動の伝達を効果的に遮断できる高遮音階段を提供する。【解決手段】Ｌ字型に接合される二枚の廻り側板１３，１４によって廻り段板の外側端部が支持される廻り段部と、平行に配置される二枚の直側板１５，１６によって矩形段板の両端部がそれぞれ支持される直状部とを有し、階下側の床面上に、階段室の内壁と接触しない自立フレーム１が形成され、廻り側板１３，１４及び廻り段板が、階段室の内壁から間隔を置いた位置で、内壁から独立して自立フレーム１上に支持され、直側板１５，１６の上端部が自立フレーム１上に支持されている。【選択図】図５
