本発明は、コンクリート床スラブに直接接着施工される
直貼り木質床材の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in a directly bonded wooden flooring material that is directly adhered to a concrete floor slab.
（従来の技術）
一般に、この種の直貼り木質床材は、コンクリート床ス

成されている。(Prior art) Generally, this type of directly attached wooden flooring is provided with a foamed resin sheet as a backing material on the back side of the wooden flooring body in order to absorb the unevenness of the concrete floor slab and make it easier to conform to. It is constructed by providing fiber materials such as wood fibers or hemp fibers.

−６０の性能が限度である。(Problem to be Solved by the Invention) However, among the above-mentioned conventional directly bonded wooden flooring materials, in the case of those that use a foamed resin sheet as the backing material, when the foamed resin foam is crushed, it loses its resilience and the floor surface There is a problem with sinking. Particularly, in areas where heavy objects such as furniture are placed, the sinking is noticeable and the sinking does not return to its original state. Furthermore, since the air inside the foam is confined, when a floor impact is applied, the impact force is likely to be transmitted to the floor slab while the internal pressure is high, making it impossible to reduce floor impact noise. The sound insulation performance according to JIS-A-1418 floor impact test is L at the lightweight floor impact sound level of the Architectural Institute of Japan standards.
-60 performance is the limit.
また一方、木質繊維や麻繊維の繊維材を裏打ち材とする

結合が外れ、繊維材内部の剥離や床材本体からの剥離を
生じ易く、これらのことから復元性に欠けるのである。On the other hand, when the backing material is made of wood fibers or hemp fibers, there are problems in terms of restorability and soundproofing, similar to the case where the above-mentioned foamed resin sheet is used as the backing material. In other words, in wood fibers and hemp fibers, the bonds between the fibers loosen and soften due to moisture, and the thickness in the compressed state decreases and changes, and the bonds between the fibers come off due to repeated compression and decompression, causing the interior of the fiber material to peel. It also tends to peel off from the main body of the flooring material, and due to these reasons, it lacks restorability.
また、繊維自体が通直に近いので、繊維のバネ作用が小
さく、圧縮されたときの衝撃エネルギーが床スラブに伝
達し易く、このことから防音性に欠けるのである。Furthermore, since the fibers themselves are almost straight, the spring action of the fibers is small, and the impact energy when compressed is easily transmitted to the floor slab, resulting in a lack of soundproofing properties.

A fiber density of 0.01 to 0.08 g/cm made by crimped synthetic fibers that are self-fused by heat at the intersections of the fibers to form a three-dimensional network structure.
The structure is such that a fibrous cushioning material of ” is attached integrally.

スラブからの湿気によって減少することもない。(Function) According to the above configuration, in the present invention, the fibrous cushioning material used as the lining material of the flooring material is made of crimped synthetic fibers that are self-fused by heat at the intersection points of the fibers to form a three-dimensional network structure. Therefore, unlike wood fibers, hemp fibers, etc., slippage or peeling does not occur at the bonded portions of the fibers, and the restorability is good and stable. Moreover, since the fibers are not softened by moisture, the thickness of the fibrous cushioning material will not be reduced by moisture from the concrete floor slab.

きる。Moreover, the crimped fibers constituting the above-mentioned fibrous cushioning material are fiber-
Each member exerts a large spring action, resulting in high impact force absorption and soundproofing properties. Moreover, since the fibers are interconnected with each other in a three-dimensional network structure, compressive deformation in the vertical direction is easily transmitted in the horizontal direction due to the spring action of the crimped fibers, and the soundproofing properties are improved by dispersing and absorbing impact energy. It can be further enhanced. Furthermore, the fiber density is 0
Because it has a low density of ゜01~0.08g/cm3,
Air flow during compression occurs on the lower surface of the flooring material, preventing air pressure from increasing, thereby further improving soundproofing properties.

設けて曲げ変形し易くすることが望ましい。FIG. 1 shows a directly attached wooden flooring material A according to an embodiment of the present invention. It consists of a fibrous cushioning material 3 attached. At the peripheral edge of the flooring main body 1, there is a male or female joint portion 1 for joining with other flooring materials A.
a is formed. In addition, the thickness of the flooring main body 1 is as follows:
It is desirable to set the thickness thinner than the normal plywood flooring body (about 12 mm) in conventional direct-laminated wood flooring because the floor impact force can be absorbed by the bending deformation of the entire flooring, and it particularly improves soundproofing properties. In order to achieve this, it is desirable to set the thickness to about 4 to 8 mm, or to provide a groove or the like on the back surface to facilitate bending and deformation.

0. 08 g/cm3. Here, the synthetic fibers may be any of nylon, polyester, polypropylene, etc., but those made of polypropylene or nylon fibers, which have particularly excellent alkali resistance, are preferable because of the alkali components from the concrete floor slab 4 (see Figure 2). It is desirable that the soundproofing properties are maintained well even after a long period of time since construction is completed. In particular, polypropylene fibers with a fiber diameter of 20 to 50 microns are desirable because they do not reduce in thickness under the load of furniture, can stably support the floor surface, and have a good walking feel. Further, as the synthetic fiber, one in which carbon is mixed to increase the toughness may be used. The crimped fibers of such synthetic fibers are fibers 3a, as shown in FIG.

It is also possible to intervene.

Then, each directly attached wooden flooring material A is pasted and laid on the concrete floor slab 4 with the adhesive 5 with the fibrous cushioning material 3 side facing downward. At this time, the unevenness of the floor slab 4 is absorbed by the deformation of the fibrous cushioning material 3 of the wooden flooring material A, so that the wooden flooring material A easily conforms to the floor slab 4.

この点からも復元性がより一層良好なものとなる。Furthermore, the above-mentioned fibrous cushioning material 3 is made of crimped fibers of synthetic fibers such as polypropylene that are self-fused by heat at the intersection points of the fibers to form a three-dimensional network structure, and the bond between the fibers is strong. Because of this, unlike wood fibers or hemp fibers, slippage or peeling does not occur at the joints of the fibers due to repeated compression and restoration, and the restoration properties are good and stable. Moreover, since this synthetic fiber does not soften due to moisture, the thickness of the fibrous cushioning material 3 and, by extension, the directly attached wooden flooring material A will not be reduced by moisture from the concrete floor slab 4, and it has excellent moisture resistance.
From this point of view as well, the restorability becomes even better.

Furthermore, since the fibers 3a and 3a are interconnected with each other in a three-dimensional network structure, compressive deformation in the longitudinal direction is easily transmitted in the lateral direction due to the spring action of the crimped fibers, and floor impact energy is dispersed and absorbed. This further improves soundproofing properties. Furthermore, the fiber density is 0.01 to 0.08
Since it has a low density of g/cm3, air flow during compression occurs on the lower surface of the flooring material A, preventing an increase in air pressure, thereby making it possible to further improve soundproofing properties. here,
The fiber density was set to 0.01 to 0.08 g/cm3 because
This is because if the value exceeds this value, the flow of air will be hindered and the floor impact force will easily propagate to the floor slab 4. If it is less than this value, the amount of compressive deformation will increase and the floor surface (floor material A
This is because the upper surface of the
