The present invention relates to an excellent floor soundproofing base material, a floor soundproofing finish material, and a wooden soundproofing floor structure.

２ａが取付られる。[Conventional technology and its problems] Conventionally, in a wooden floor structure constructed on a concrete floor,
For example, as shown in FIG. 5, a panel having a predetermined thickness such as a particle board or a control panel as a structural plate material for receiving a floor load on a plastic support leg 2 arranged on a concrete floor 1 at appropriate intervals. Lay the board 3 on top of it, and put up a sill 4 made of, for example, plywood, and
If necessary, a surface finish material (not shown) is stretched on the scrap 4. A soundproof rubber 2a that absorbs low frequency vibrations is attached to the lower portion of the support leg 2.

この従来の床構造についてＪＩＳ−Ａ１４１８に従って
床衝撃音レベルを測定した結果、第６図に示すように遮
音等級Ｌ−５５を上回り、防音性を高める上でかなり不
利であることが分かった。According to such a conventional floor structure, low-impact vibrations that occur when an object is dropped on the floor, tied up, or slipped around while walking are difficult to be transmitted to the concrete floor 1 via the support legs 2. However, the vibration of the panel board 3 or the like that vibrates on the support legs 2 spreads over the whole area, and is transmitted to the concrete floor 1 by using air as a medium, and it will be heard as noise by the inhabitants downstairs. . That is,
As a result of measuring the floor impact sound level of this conventional floor structure in accordance with JIS-A1418, it was found that it exceeded the sound insulation grade L-55 as shown in FIG. 6 and was considerably disadvantageous in enhancing sound insulation.
そこで、例えば第７図に示すように、床の防音性を高め
るために、パネルボード３上に積層した下捨張４ａの上

振シート８、及び表面仕上げ材７を積層した、計７層構
造の防音床構造を考案した。Therefore, for example, as shown in FIG. 7, in order to improve the soundproofing of the floor, from a rubber sheet having a thickness of 5 mm in which felt 5 and lead are contained in the upper layer of the subdivision 4a laminated on the panel board 3. Laminated with a low-resilience rubber block sheet 6
A soundproof floor structure having a total of 7 layers was devised by laminating the upper part 4b, the damping sheet 8 made of a synthetic resin having a thickness of about 1 mm, and the surface finishing material 7 thereon.
しかしながら、この先考案によっても第８図に示すよう

工性を高める上でも不利である。However, even according to this prior invention, as shown in FIG. 8, it exceeds the sound insulation grade L-50, and there is still some dissatisfaction in enhancing the soundproofing. Further, the low resilience rubber block sheet 6 intervenes, so that the floor unit can be easily separated. There is a problem that the weight (weight per unit area) becomes heavy. Further, the low-resilience rubber block sheet 6 cannot be cut using a cutter knife or the like, and cannot be cut without using a saw, which is also disadvantageous in improving workability.

が分かった。By the way, the felt is used as a sound-absorbing and sound-insulating material, for example, in halls, ceilings of broadcast rooms, wall linings, etc.
It may also be used as a surface finishing material for floors in offices and the like. However, these conventional felts used as linings or surface finishes have a relatively soft finish in consideration of the texture, and also have low compression elasticity. It has been found that even if a thicker felt is used instead of the sheet 6, the sheet 6 will be worn out in a relatively short time, and it will be difficult to maintain high soundproofness for a long period of time.
本考案は、上記の事情を考慮してなされたものであっ

る。Since the soundproofing base material according to the present invention is made of felt reinforced with resin on both front and back surfaces, the unit weight is much lighter than the conventional soundproofing material made of rubber block sheet containing lead. The cost can be reduced, and high soundproofness lower than the sound insulation grade L-50 can be obtained. In addition, by reinforcing both the front and back sides with resin, the surface hardness and compression elasticity are stronger than conventional felt for lining or floor surface finishing, so it has excellent durability and retains excellent soundproofing for a long period of time. be able to. Furthermore,
Since the soundproofing material can be easily cut with a cutter knife or can be sawn together with the plate material attached to the soundproofing material and cut at the same time, the workability can be improved.

The felt may be formed by a known method. For example, when a fiber having no felting property such as synthetic fiber scrap is used as a raw material, a needle punch having a barb is pierced to make a felt-like needle punch. You can make it according to the law.

い。The prepared raw material R made of synthetic fiber scraps is mixed by the mixing machine 11, the fiber direction is adjusted to the parallel direction or the cross direction by the hair trimming machine (lap former) 12, the hardener 13 is used for molding, and then the needling machine 14 is used. Needling process (needle punching process). After the needling, the felt is impregnated with the resin by resin coating or dipping, migration processing is performed to concentrate the resin on both front and back surfaces of the felt, and the felt is dried by a dryer 15. If the resin is dispersed in the whole felt, the surface strength of the felt tends to be insufficient, and if a large amount of the resin is contained to obtain sufficient surface strength, the resin becomes rigid and the workability is impaired, which is not preferable. The resin to be impregnated may be a thermosetting resin such as a melamine resin, or may be a thermoplastic resin such as an olefin resin. After this,
About 50 with press 16 such as rotary press and flat press
It is pressed with a ton of pressure to make the thickness uniform, and is finished into a roll through a finishing process. After needling, insect repellent,

Therefore, the workability can be significantly improved as compared with the case of laying a low-resilience rubber block sheet that is heavy and requires a saw for cutting. Further, the panel board 3 and the sash 4 are adhered to each other using an adhesive, but since the resin is concentrated on both the front and back surfaces of the soundproofing material 9, it is easy to get wet with the adhesive and exhibits high adhesiveness. It is not necessary to use an expensive epoxy-based adhesive used when bonding a low-repulsion rubber block sheet for vibration damping, and an inexpensive adhesive may be used.

In order to prevent the adhesive from sticking and to sufficiently enhance the adhesive strength of the adhesive, the curing vinyl 20 is releasably attached to the surface. The soundproofing base material 9 is made according to the procedure shown in FIG. 2, and the male tongue 17a is formed on one side of the tongue-joining veneer 17 and the female tongue 17b is formed on the other side.

が高いといえる。According to this floor soundproof wood finishing material, although not shown here, the floor soundproof wood finishing material is bonded to the upper surface of the panel board supported by the supporting legs on the concrete floor with the back surface facing downward. By doing so, a floor structure similar to the floor structure shown in FIG. 1 can be constructed, and a light-weight, high-soundproof and inexpensive soundproof floor structure with a wood finish can be obtained. In other words, it can be said that this floor soundproof wood finishing material is lightweight and highly soundproof.
