DYNAMIC VIBRATION REDUCER AND CEILING STRUCTURE
To provide a dynamic vibration reducer which prevents elastic parts from separating from a ceiling board even when receiving an impact from the ceiling board and enables stable management of dynamic vibration absorption performance.SOLUTION: A dynamic vibration reducer includes: first elastic parts 22 provided on a lower surface of a mass part 21; a pair of attachment parts 31 which are attached to two ceiling joists, restricted from moving upward; holding means having an extending part 32 which is fixed to the pair of attachment parts 31 and holds the mass part 21 and the first elastic parts 22 so that loads of the mass part 21 and the first elastic parts 22 are supported by the ceiling joists and lower surfaces of the first elastic parts 22 are located lower than a lower surface of each ceiling joist in a state that the pair of attachment parts 31 is attached to the ceiling joists; and second elastic parts 23 provided on the mass part 21 and compressed between the pair of attachment parts 31 and a ceiling board in a state that the ceiling board is attached to the ceiling joists.SELECTED DRAWING: Figure 2
【課題】天井ボードからの衝撃をうけても弾性部が天井ボードから離れることがなく、かつ、動吸振性能の安定した管理が可能な動吸振装置を提供する。【解決手段】動吸振装置は、質量部２１の下面に設けられる第１弾性部２２と、上方への移動が規制された状態で２本の野縁に取り付けられる一対の取付部３１と、一対の取付部３１に固定されているとともに、一対の取付部３１が野縁に取り付けられた状態において、質量部２１および第１弾性部２２の荷重を野縁に預け、かつ、第１弾性部２２の下面が野縁の下面よりも下に位置するように質量部２１および第１弾性部２２を保持する延伸部３２を有する保持手段と、質量部２１の上に設けられているとともに天井ボードが野縁に取り付けられた状態において一対の取付部３１と天井ボードとの間で圧縮される第２弾性部２３とを備える。【選択図】図２
