本発明は、コンクリート床スラブに直接接着施

維や麻繊維の繊維材を設けて構成されている。(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.

ことができない。JIS−Ａ−1418の床衝撃試験に
よる遮音性能では日本建築学会基準の軽量床衝撃
音レベルでＬ−60の性能が限度である。(Problems to be solved by the invention) However, among the above-mentioned conventional directly attached wooden flooring materials,
In the case of a backing material using a foamed resin sheet, there is a problem in that when the foamed resin foam is crushed, it loses its resilience and the floor surface sinks. Sinking is particularly noticeable in areas where heavy objects such as furniture are placed.
And the sinking is irreversible. 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 even when the internal pressure is high, making it impossible to reduce floor impact noise. The sound insulation performance according to the floor impact test of JIS-A-1418 is limited to the performance of L-60 at the lightweight floor impact sound level of the Architectural Institute of Japan standards.
また一方、木質繊維や麻繊維の繊維材を裏打ち

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, moisture loosens the bonds between the fibers and softens them, causing the thickness to decrease and change in the compressed state, and repeating compression and decompression causes the bonds between the fibers to come off, causing the fibers to soften. It is easy for the interior of the material to peel off or to peel off from the flooring itself, which results in a lack of restorability. 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.
本発明はかかる点に鑑みてなされたものであ

ものである。 The present invention has been made in view of these points, and its purpose is to provide a directly bonded wooden flooring material with excellent resilience and soundproofing properties by using an appropriate fiber material as a backing material. It is something to do.

A fibrous cushioning material with a fiber density of 0.01 to 0.08 g/cm 3 is made by bonding crimped synthetic fibers into a three-dimensional network structure by self-fusion using heat at the intersections of the fibers, and is attached together. This is what I did.

スラブからの湿気によつて減少することもない。(Function) With the above configuration, in the present invention, the fibrous cushioning material used as the lining material of the flooring material combines crimped synthetic fibers into a three-dimensional network structure by self-fusion by heat at the intersection points of the fibers. 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. Furthermore, since the fibers do not soften due to moisture, the thickness of the fibrous cushioning material does not decrease due to moisture from the concrete floor slab.

ことができる。 Furthermore, since each of the crimped fibers constituting the fibrous cushioning material exhibits a large spring action, the crimped fibers exhibit high impact force absorption and soundproofing properties. Moreover, since the fibers are interconnected 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 is achieved by dispersing and absorbing impact energy. Sexuality is further enhanced. Furthermore, the fiber density
Since it has a low density of 0.01 to 0.08 g/cm 3 , air flow during compression occurs under the flooring material, preventing an increase in air pressure, thereby further improving soundproofing properties.

It consists of a fibrous cushioning material 3 that is integrally attached. A male or female joint part 1a for joining with another flooring material A is formed on the peripheral edge of the flooring main body 1. The thickness of the floor body 1 is set to be thinner than the thickness of the normal plywood floor body (approximately 12 mm) in conventional direct-laminated wood flooring to prevent floor impact force from bending deformation of the entire flooring. In particular, in order to improve soundproofing properties, it is desirable to set the thickness to about 4 to 8 mm, or to provide grooves or the like on the back surface to make it easier to bend and deform.

なつている。 The fibrous cushioning material 3 is made by combining crimped synthetic fibers into a three-dimensional network structure by self-fusion by heat at the intersection points of the fibers, and the fiber density is 0.01 to 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, can be used as synthetic fibers from the concrete floor slab 4 (see Figure 2). It is desirable because it does not deteriorate due to alkaline components and its flexibility and compression recovery properties do not deteriorate, so it maintains good soundproofing properties even after a long period of time has passed after construction. In particular, polypropylene fibers with a fiber diameter of 20 to 50 microns are desirable because they can stably support a floor surface without reducing the thickness under the load of furniture, and also have a good walking feel. In addition, as a synthetic fiber,
A material with increased toughness by mixing carbon may also be used. As shown in FIG. 3, such crimped synthetic fibers include fibers 3a, 3a,...
...Each fiber has a three-dimensionally crimped shape, and the fibers 3a and 3a are
They are also bonded to each other by thermal self-fusion at their intersection points. The structure of this crimped fiber is similar to that of a large number of coil springs s, as shown in FIG.
s, . . . are connected to each other in a three-dimensional network.

It is also possible to intervene.

み易くなる。 Next, to explain the function and effect of the above embodiment, as shown in FIG.
While joining at joints 1a, 1a, each directly attached wooden flooring material A is adhered and laid on a concrete floor slab 4 with an 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, and the wooden flooring material A becomes easier to conform to the flooring slab 4.

層良好なものとなる。 Moreover, the fibrous cushioning material 3 is made by bonding crimped synthetic fibers such as polypropylene into a three-dimensional network structure by self-fusion by heat at the intersection points of the fibers, and the bonding between the fibers is strong. Because it is a solid material, slipping or peeling does not occur at the joints of the fibers due to repeated compression and restoration, as is the case with wood fibers and hemp fibers, 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 the directly attached wooden flooring material A is equal to that of the concrete floor slab 4.
It does not decrease due to moisture from outside and has excellent moisture resistance, and also from this point of view, the restorability is even better.

じるからである。 Further, each of the crimped fibers constituting the fibrous cushioning material 3 exhibits a large spring action, so that the absorbency against floor impact force and the soundproofing property are high. Moreover, since the fibers 3a, 3a are interconnected 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.
Soundproofing properties are further improved by dispersing and absorbing floor impact energy. Furthermore, the fiber density is 0.01~0.08g/
Due to its low density of cm 3 , air flow during compression occurs on the underside of flooring material A, preventing air pressure from increasing.
Thereby, soundproofing properties can be further improved. Here, the reason why the fiber density is set to 0.01 to 0.08 g/cm 3 is because if it exceeds this value, air flow is obstructed and the floor impact force tends to propagate to the floor slab 4. This is because if it is below, the amount of compressive deformation will become large and the floor surface (the upper surface of the floor material A) will sink.

いし防音性が大巾に向上する。 Here, in order to demonstrate the soundproofing effect of the present invention, we applied a lightweight floor impact force according to JIS-A-1418 and measured the impact sound level of the floor impact sound downstairs. Figure 5 shows the results of an experiment regarding the sound insulation performance against impact noise. In this experiment, as an example of the present invention, a 4 mm thick fibrous cushioning material (using crimped polypropylene fibers) 3 was attached to the back side of a 7 mm thick plywood flooring body 1. there was. In addition, as a first comparative example, a 2 mm thick foamed polyethylene resin sheet was attached to the back side of a 12 mm thick plywood flooring body, and as a second comparative example, a 7 mm thick plywood floor material was attached. A foamed polyethylene resin sheet with a thickness of 8 mm was attached to the back side of the material itself.
As can be seen from FIG. 5, in the case of the first and second comparative examples, the sound insulation performance was L-67 and L-60, respectively, at the lightweight floor impact sound level of the Architectural Institute of Japan standards, whereas the present invention example In the case of , it is L-55, and the sound insulation property or soundproofing property is greatly improved.
