Inorganic foam material or foamed synthetic resin material such as polyolefin, plywood, particle board, concrete panel, etc., and vinyl chloride damping sheet are laminated if necessary, but when laying or placing directly Since the former layer of foam material or the like sinks over time and causes distortion on the floor surface, wooden or metal joists are used to support the floor material in order to eliminate this sinking.

なるので、好ましい解決法とはなり難かった。However, since the support by joists directly propagates the sound, especially the impact sound, from the floor base to the lower part (lower floor) through the wide joint surface of the joists, the original purpose of the soundproofing is to achieve. It is a solution idea that does not conform to the above and is not preferable in this respect. In order to eliminate this drawback, there is also the idea of sandwiching foam material on either the upper or lower surface of the joist, but this is to add the cause of subduction to the joist to prevent subduction. Therefore, it was difficult to obtain a preferable solution.

また、発泡層に代えて緩衝層を採用し得る。The foaming layer may be a closed-cell foaming layer, an open-cell foaming layer, or a laminated structure of both, so that the damping effect can be selectively adopted.
A buffer layer may be used instead of the foam layer.

層好ましいものとなる。In this impact sound damping floor, the floor strength corresponding to the application can be realized by setting the strength of the protrusion to a desired level, and at the same time, the floor deformation due to the foam layer or the like does not occur. . The slight elasticity of the protrusion cushions the impact on the foot at the time of contact with the ground, so that the walking feeling becomes more preferable.
