VIBRATION CONTROL CEILING
To prevent a ceiling member from being damaged and dropping out of the member by suppressing horizontal displacement generated in an existing suspended ceiling when an earthquake occurs.SOLUTION: A suspended ceiling is provided with a vibration control mechanism comprising a plurality of pulley groups each comprising a movable pulley unit having a coaxial movable pulley and a fixed pulley unit having a coaxial fixed pulley opposed to the movable pulley unit, a braking damper, and a wire stretched between each pulley group and the braking damper. When the suspended ceiling is displaced at the time of the occurrence of an earthquake, and when the wire generates a predetermined displacement between the pulley groups, the displacement amount of the wire is amplified with respect to the relative displacement amount generated in the suspended ceiling, and the wire passes through the braking damper by the displacement amount, so that the energy input to the suspended ceiling is attenuated.SELECTED DRAWING: Figure 1
【課題】 地震発生時に、既存の吊り天井に生じる水平変位を抑制して天井部材の破損、脱落防止を図る。【解決手段】 同軸動滑車を有する動滑車ユニットと、動滑車ユニットと相対する同軸定滑車を有する定滑車ユニットとからなる複数の滑車群と、制動ダンパーと、各滑車群、制動ダンパーの間を掛け渡されるワイヤーとからなる制振機構を吊り天井に設ける。地震発生時に、吊り天井が変位した際に、ワイヤーが滑車群間で所定の変位を生じた際、そのワイヤー変位量が、吊り天井に生じた相対変位量に対して増幅され、ワイヤーが変位量分、制動ダンパー内を通過することで吊り天井に入力されたエネルギーが減衰される。【選択図】 図１
