PROBLEM TO BE SOLVED: To allow relative displacement of a restraining layer of a damping material to a steel wall to further increase damping effect of the damping material and reduce a noise level in a living quarter.SOLUTION: A damping material 1 includes a restraining layer 2 and a viscoelastic layer 3 formed of a viscoelastic material. The restraining layer 2 is fastened with the viscoelastic layer 3 by a fastening member A.SELECTED DRAWING: Figure 3
【課題】制振材の拘束層と鋼壁との相対的な変位を許容させることができるようにして制振材による制振効果をより一層高めて居住区内の騒音レベルを低減する。【解決手段】制振材1は、拘束層2と粘弾性材からなる粘弾性層3とを有している。拘束層2が粘弾性層3と共に締結部材Aによって締結される。【選択図】図3
