VIBRATION DAMPING DEVICE FOR FLOOR
To provide a vibration damping device for a floor capable of effectively dumping vibration in a floor structure.SOLUTION: A vibration damping device for a floor comprises: a rigid plate arranged on either or both of an upper surface and a lower surface on a floor structure of a structure apart from the surface; an anti-vibration supporting mechanism connecting the rigid plate to the floor structure in a vibration isolation condition; and a damping member arranged with pre-compression applied between the floor structure and the rigid plate, wherein the damping member is arranged on a side of the rigid plate and comprises: a first rubber layer of which a first irregular surface is provided on a side of the floor structure; and a second rubber layer of which a second irregular surface press-abutted on the first irregular surface of the first rubber layer in a way that both of the irregular surfaces correspond to each other, is provided on the side of the rigid plate.SELECTED DRAWING: Figure 3
【課題】良好に床構造体の振動を減衰することのできる床用振動減衰装置を実現する。【解決手段】この床用振動減衰装置は、構造物の床構造体の上下いずれか一方の面または、両方の面に、該面に対して離間して配置された剛性板と、剛性板を床構造体に対して振動絶縁状態で連結する防振支持機構と、床構造体と剛性板との間に予圧縮が付与されて配置された減衰部材とを有する床用振動減衰装置であって、減衰部材が、剛性板側に配置され、床構造体側に第１の凹凸面が設けられた第１ゴム層と、第１ゴム層と床構造体との間に配置され、剛性板側に第１ゴム層の第１の凹凸面と雄雌対応して圧接する第２の凹凸面が設けられた第２ゴム層とを有するものである。【選択図】図３
