た。[Prior Art] In recent years, floor impact noise from the upper floors has become a serious problem in apartment buildings and the like. The floor impact sound includes a floor impact sound due to a light weight impact that is usually caused by walking and a floor impact sound due to a heavy impact caused when a heavy object is dropped or a child jumps up. For, there was no effective solution other than thickening the floor slab.

Although it has a structure that absorbs impact vibration noise by the elastic force of the sheet, it is necessary to provide protrusions on both the floor base material and the floor bottom material, so there is a large vertical gap between the floor base material and the floor bottom material. There is a problem that it cannot be applied to an existing building because it requires dimensions and the opening and closing doors cannot be opened and closed.
