ト層を設けているものである。(Prior Art) In general, it is structurally unavoidable that the floor Vl'I knocking sound that occurs when living in an apartment complex is transmitted to the lower floor, but this sound can be lowered and alleviated to some extent. BACKGROUND ART Conventionally, as a sound insulating floor structure against impact noise (particularly weight impact sound) applied to a floor, a floor constructed by, for example, a wet floating floor construction method is known. This floor is made by placing glass wool on the floor slab.
On top of that is a mortared concrete layer with built-in wire mesh.

部位に対応するものである。(Means for Solving the Problems) The present invention has a dynamic vibration absorber attached to the floor slab via a spring body, and the position of this dynamic vibration absorber on the floor slab is such that the response vibration of the floor slab is not affected. This corresponds to the area with the maximum amplitude, which is located in the area that is detrimental to sound insulation.
（実施例） 以下本発明の実施例を図面を参照して説明する。(Example) Embodiments of the present invention will be described below with reference to the drawings.

の取付は板４を設けている。In FIG. 1, in the response vibration curve S of the floor slab 1, the part 1 which is harmful to sound insulation is the part 1 where the vJ vibration absorber 3 is horizontally attached to the floor slab surface at the position corresponding to the large amplitude parts P1 and P2 via the spring body 2. Installation: This dynamic vibration absorber is made of a concrete plate, a steel plate, etc., and the spring body 2 must be attached to the top surface of the dynamic vibration absorber as shown in Figures 1 and 2. , is made up of springs, anti-vibration rubber, etc., but in the illustrated example, a coil spring is used, and a mounting plate 4 is provided at the upper end for fixing to the lower surface of the floor slab 1.

ないが、その後の衝撃音を低く抑えることができる。The dynamic vibration absorption ('a sound) function by the floor structure of the present invention was confirmed through experiments. The waveform of floor impact sound is compared with the waveform of floor impact sound.In this figure, the waveform W shown by the chain line is the core of the present invention, and the waveform Wa shown by the solid line is
The waveform W of the present invention is similar to the waveform Wa with respect to the initial amplitude.
The waveform gradually attenuates and becomes shorter, and a dynamic vibration absorption effect is observed. Therefore, in the present invention, although the initial impact noise hardly changes, subsequent impact noises can be suppressed to a low level.
