STEEL STAIRCASE STRUCTURE
To provide a steel staircase structure suppressed in deterioration of walking feeling felt by a pedestrian when walking up/down the steel staircase structure, and in transmission of walking sound on the staircase felt in an adjacent room of the structure.SOLUTION: A steel staircase structure 1 has a steel staircase body 2 with at least one end connected to a structural skeleton 3, a connection part 4 for connecting the steel staircase body 2 to the structural skeleton 3 via a first vibration-proof material 41, and a vibration control device 5 fixed to the steel staircase body 2.SELECTED DRAWING: Figure 4
【課題】 鉄骨階段構造の昇降時に歩行者が知覚する歩行感が振動によって悪化することを抑制するとともに、鉄骨階段構造の隣室で知覚される階段の歩行音の伝搬を抑制することができる鉄骨階段構造を提供する。【解決手段】鉄骨階段構造１は、少なくとも一端が構造躯体３に接続される鉄骨階段本体２と、前記鉄骨階段本体２を前記構造躯体３に第一防振材４１を介して接続する接続部４と、前記鉄骨階段本体２に固定される制振装置５と、を備える。【選択図】図４
