DYNAMIC VIBRATION ABSORBING DEVICE AND CEILING
To provide a dynamic vibration absorbing device capable of preventing deformation of an elastic body during ceiling board construction and preventing deterioration of vibration-reducing performance, and a ceiling equipped with the dynamic vibration absorbing device.SOLUTION: A dynamic vibration absorbing device 1 comprises: a mass body 6; an elastically deformable elastic body 7 provided on a lower surface 6a of the mass body 6; temporary holding means 9 for temporarily holding the mass body 6 to two ceiling joists 2 so that the elastic body 7 protrudes below the ceiling joists 2 between the two ceiling joists 2 in a state before a ceiling board 5 is fixed to the two ceiling joists 2 and the elastic body 7 is placed on the ceiling board 5 by attaching the ceiling board 5 to the two ceiling joists 2; and low friction means 8 interposed between the elastic body 7 and the ceiling board 5 and having a friction resistance smaller than a friction resistance between the ceiling board 5 and the elastic body 7.SELECTED DRAWING: Figure 5
【課題】天井ボード施工時における弾性体の変形を防止し、振動低減性能の低下を防ぐことが可能な動吸振装置およびこれを備えた天井を提供する。【解決手段】動吸振装置１は、質量体６と、質量体６の下面６ａに設けられた弾性変形可能な弾性体７と、天井ボード５が２本の野縁２に固定される前の状態において２本の野縁２の間で弾性体７が野縁２の下方に突出するとともに天井ボード５が２本の野縁２に取り付けられることにより弾性体７が天井ボード５に載置されるように、質量体６を２本の野縁２に仮保持する仮保持手段９と、弾性体７と天井ボード５との間に介在し、天井ボード５と弾性体７との間の摩擦抵抗よりも小さな摩擦抵抗となる低摩擦手段８とを備える。【選択図】図５
