VIBRATION ATTENUATION DEVICE AND VIBRATION ATTENUATION STRUCTURE
PROBLEM TO BE SOLVED: To provide a vibration attenuation device and a vibration attenuation structure having a simple configuration.SOLUTION: A vibration attenuation device 5 is used while being fixed on a ceiling part of a hanging ceiling. The vibration attenuation device 5 comprises an external box 11, a weight part 13 stored in the external box 11, a roller 15 arranged at a lower surface of the weight part 13, springs 17 and the like for connecting an external surface of the weight 13 and an internal surface of the external box 11. The weight part 13 has a container 21 and several weight bodies 23 filled in the container 21. The vibration attenuation device 5 performs a vibration attenuation function when the weight part 13 fixed with the springs 17 is moved to enable oscillation of the ceiling to be reduced at the time of occurrence of earthquake. In addition, when the weight part 13 is moved, it is possible to sustain the ceiling vibration fast through attenuation effect caused by friction accompanied with motion of the weight bodies 23 filled in the container 21 or collision of the weight bodies 23.SELECTED DRAWING: Figure 2
【課題】簡易な構成の制振装置および制振構造を提供する。【解決手段】制振装置５は吊り天井の天井部の上に固定して用いられる。制振装置５は、外箱１１、外箱１１に収容された錘部１３、錘部１３の下面に設けられたローラ１５、および錘部１３の外側面と外箱１１の内側面とを接続するバネ１７等を具備する。錘部１３は、容器２１と、容器２１に充填される複数の錘体２３を有する。制振装置５は、バネ１７を取付けた錘部１３が移動する際に制振機能を発揮し、地震時等の天井揺れを減少できる。また錘部１３の移動時には、容器２１内に充填した錘体２３の移動に伴う摩擦や錘体２３の衝突によるエネルギー消費がもたらす減衰効果により、天井揺れを早く収めることができる。【選択図】図２
