STAIRCASE
To provide a staircase that can suppress the vibration of a building while ensuring the degree of freedom of design of the building.SOLUTION: A staircase body composed of a kicking portion and a tread surface portion, part or all of which are formed of an energy absorbing member that absorbs vibration energy, an upper fixing part for fixing the upper end of the staircase body to the upper floor building frame, a lower fixing portion for fixing a lower end portion of the staircase body to a lower floor building frame, a vertical girder having an upper end supported by the upper floor building frame and a lower end supported by the lower floor building frame in which at least one of the upper end or the lower end is allowed to move in the length direction, and a support portion that is provided on vertical girder and supports the tread surface portion of the staircase body.SELECTED DRAWING: Figure 1
【課題】建物の設計自由度を確保しつつ建物の振動を抑制することができる階段を提供する。【解決手段】蹴込部と踏面部で構成され、一部又は全部が振動エネルギーを吸収するエネルギー吸収部材で形成された階段本体と、前記階段本体の上端部を上階躯体に固定する上部固定部と、前記階段本体の下端部を下階躯体に固定する下部固定部と、上端部が前記上階躯体に支持されるとともに下端部が前記下階躯体に支持され、上端部又は下端部の少なくとも一方が長さ方向へ移動が許容されたささら桁と、前記ささら桁に設けられ前記階段本体の前記踏面部を支持する支持部と、を有する。【選択図】図１
