DYNAMIC VIBRATION REDUCER AND CEILING STRUCTURE
To provide a dynamic vibration reducer which can inhibit deformation of a plurality of elastic bodies during construction in a structure having the elastic bodies.SOLUTION: A dynamic vibration reducer 10 is installed on a ceiling 1 including two ceiling joists 2 arranged at an interval and a ceiling board 5 fixed to lower surfaces 2a of the ceiling joists 2. The dynamic vibration reducer 10 includes: at least one mass part 21; a plurality of elastic parts 22 provided at one area of a lower surface 21a of the mass part 21; a support member 30 which is attached to the two ceiling joists 2 in a state that loads of the mass part 21 and the elastic parts 22 are supported by the two ceiling joists 2; and connection plates 40 each connecting the elastic parts 22 with each other. The support member 30 is configured to be attachable to the two ceiling joists 2 in a state that lower surfaces 40b of the connection plates 40 are located at the lower level than the lower surfaces 2a of the two ceiling joists 2 so that the ceiling board 5 is attached to the lower surfaces of the ceiling joists 2 to allow loads of the at least one mass part 21, the elastic parts 22, and the connection plates 40 to be supported by the ceiling board 5.SELECTED DRAWING: Figure 7
【課題】複数の弾性体を有する構成において施工時における弾性体の変形を抑制することが可能な動吸振装置を提供する。【解決手段】動吸振装置１０は、互いに間隔を空けて配列された２本の野縁２と野縁２の下面２ａに固定された天井ボード５とを備えた天井１に設置され、少なくとも１つの質量部２１と、質量部２１の下面２１ａの一部の領域に設けられる複数の弾性部２２と、質量部２１および複数の弾性部２２の荷重を２本の野縁２に預けた状態で２本の野縁２に取り付けられる支持部材３０と、複数の弾性部２２同士を連結する連結板４０とを備える。支持部材３０は、野縁２の下面に天井ボード５が取り付けられることにより少なくとも１つの質量部２１、複数の弾性部２２、および連結板４０の荷重を天井ボード５に預けることができるように、連結板４０の下面４０ｂが２本の野縁２の下面２ａよりも下に位置した状態で２本の野縁２に取付可能に構成されている。【選択図】図７
