DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden vibration-absorbing floor panel directly attached to a floor base such as a concrete slab of an apartment house, a general house, and various other buildings.

[0002]

2. Description of the Related Art Conventionally, as a wooden vibration-isolating floorboard of this kind, a plurality of cut grooves are provided at appropriate intervals on the lower surface side of a wooden substrate, for example, a laminated board whose surface is decorated. As a cushioning material, there is a material in which a fiber mat having a single-layer structure made of a thick fiber having a fiber diameter of about 15 to 30 denier is stuck with an adhesive.

[0003]

Generally, a wooden vibration-isolating floorboard of this kind is applied with a pressing force of a constant pressure by a holding roll 5 while a fiber mat 4 is adhered to a wooden substrate 3 as shown in FIG. In this state, it is cut or actually processed by the saw blade cutter 6.

However, in the conventional wooden vibration-isolating floorboard, since the cushioning material is a single-layer fiber mat, the fiber mat 4 is cut into the lower surface of the wooden substrate 3 as shown in FIG. 31 and in this state the cutter 6
When cutting is performed, fluffing occurs. That is, when the fiber mat 4 has a single-layer structure and a large fiber diameter, cutting with the cutter 6 without applying a pressing force causes baldness, and it is difficult to cut the end face sharply. And the above-mentioned fluffing occurs. for that reason,
As shown in FIGS. 9 and 10, there is a problem that the fluff 41 protrudes from the end of the cut groove 31 of the floorboard, and when the floorboard is laid, the fluff 41 wraps around the surface and is easily exposed.

Further, the thickness of the fiber mat is 15-30.
When laying the floorboard on the floor base because it is as thick as denier, the adhesive such as epoxy resin enters the fiber mat and the slip resistance between the fiber mat and the floor base increases, Sliding on the floor base from the front of the floorboard to which the floorboard to be pasted was already pasted, the work of fitting and laying the actual floorboards was hindered, and there was a problem of poor workability.

[0006] It is an object of the present invention to provide a wood-based vibration-isolating floorboard that solves the conventional problems.

[0007]

In order to solve the above-mentioned problems, the present invention provides a cushioning material having a three-layer structure of a non-woven fabric, wherein the upper and lower layers are formed of non-woven fabrics of fibers having a small diameter to prevent the occurrence of fluff during processing and when laying. The intermediate layer is provided with excellent soundproofing properties as a non-woven fabric composed of fibers having a large diameter.

That is, the wooden vibration-insulating floor plate of the present invention is provided with a plurality of cut grooves or holes provided at appropriate intervals on the lower surface side of a wooden substrate, and a buffer material is adhered to the lower surface of the wooden substrate. In a wood-based vibration-isolating floorboard, the cushioning material is made of a three-layer laminate of non-woven fabric, and the upper and lower layers are made of non-woven fabric having a weight per unit area of 8 to 24 g / m ² made of thermo-adhesive fibers of 1.5 to 3 denier. The intermediate layer is made of a non-woven fabric having a basis weight of 100 to 300 g / m ² , made of 6 to 30 denier thermal adhesive fibers.

[0009]

[Function] Even if actual processing and cutting are performed by applying pressure while the cushioning material is adhered to the wooden substrate, the edge material is cut sharply without much penetration into the cut grooves and holes on the lower surface of the wooden substrate. This makes it difficult for the cushioning material to be generated as fluff from the edge of the floorboard. When the floorboard is laid on the floor base, the adhesive hardly enters the cushioning material, and the slip resistance between the floor board and the floor base is reduced.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. In the drawings, reference numeral 1 denotes a wooden substrate, and plywood, particle board, or the like is used. Wood substrate 1
May be a single wooden board, but is generally a laminated board in which wooden boards and the like are laminated.

For example, in the case of FIGS.
1, each of the wooden boards of the base board 12 and the backing board 13 is sequentially laminated and formed. In the case of FIG. 4 to FIG. 6, each of the front decorative board 11, the base board 12, and the backing board 13, the soft sheet 14 for damping, and the wood board of the base board 12 are sequentially laminated and formed. I have. As the soft sheet 14, a sheet made of soft rubber, foamed rubber, soft foamed resin, clothed soft foamed rubber, or the like is used. In addition, the laminated structure of the wood-based substrate 1 is not limited to the above-described one, and may be any as long as it is laminated so that the vibration proof property, the sound proof property and the like are improved.

A plurality of cut grooves 15 are provided on the lower surface of the wooden substrate 1 at appropriate intervals. The cut grooves 15 may be simply provided in parallel, or may be provided in a vertical and horizontal lattice. The kerf 15 generally has a width of 1 to 3.5 mm.
It is provided at an appropriate pitch depending on the thickness and configuration of the wooden substrate 1. Note that a plurality of holes may be provided at appropriate intervals instead of the cut grooves 15.

The end of the wooden substrate 1 is cut and actually processed with a cushioning material 2 to be described later adhered thereto.
6, female nuts 17 are provided. 16 male and 1 female
7 has a shape and dimensions that can fit each other.

The cushioning material 2 is composed of a three-layer laminate of a nonwoven fabric,
It is attached to the lower surface of the wooden substrate 1 with an adhesive. The upper layer 21 of the cushioning material 2 has a non-woven fabric end face that can be cut sharply to prevent the occurrence of fluff, the lower layer 22 has a good slip with the floor base, and the middle layer 23 has a soundproof property with excellent acoustic performance. Each is provided in order to demonstrate. The upper layer 21, the lower layer 22, and the intermediate layer 23 are each formed of a nonwoven fabric made of a heat-adhesive fiber, and each layer is heat-sealed. Fibers such as polypropylene, polyethylene, and polyester are used as the heat-adhesive fibers.

The nonwoven fabric of the upper layer 21 and the lower layer 22 has a thickness of 1.
It is formed from 5 to 3 denier fibers. If the thickness of the fiber is too small, a predetermined fusion strength is not obtained, and the cushioning material 2 is easily peeled off during floor plate processing or construction. Conversely, if the fiber is too thick, fluffing occurs during cutting as in the past, and adhesive Is preferably in the range of 1.5 to 3 denier, since the slippage into the middle layer 23 and the slip with the floor base become worse.

The basis weight of the nonwoven fabric of the upper layer 21 and the lower layer 22 is 8 to 24 g / m ² . If the basis weight is too small, the thickness will not be more than a predetermined thickness, and the adhesive at the time of laying the floor board will enter the intermediate layer 23, causing slippage between the floor base and the floor, and conversely, if too large, the soundproof property will be poor. At the same time, when the cushioning material 2 is manufactured, the heat does not sufficiently flow into the entire layer, resulting in poor fusion. Therefore, the above-mentioned 8 to 24 g / m ² is preferable. The thickness of each of the upper layer 21 and the lower layer 22 is generally smaller than that of the intermediate layer 23 and thinner.

The nonwoven fabric of the intermediate layer 23 is formed from fibers having a thickness of 6 to 30 denier. If the thickness of the fiber is too small or too large, the soundproofing property deteriorates.
It is preferably 30 denier. Especially 18
Denier is preferred from the viewpoint of soundproofing.

The basis weight of the non-woven fabric of the intermediate layer 23 is 100 to 300 g / m ² , though it varies depending on the thickness of the non-woven fabric. If the basis weight is too small, the floorboard is inferior in habitability and sagging is likely to occur, while if it is too large, the soundproofing property deteriorates, so the above-mentioned 100 to 300 g / m ^2.
Is preferred. Generally, the thickness of the intermediate layer 23 is set to 2.5 to 6 mm because the thickness of the intermediate layer 23 can be satisfied, such as soundproofness, livability, and the ability to cope with unevenness of the floor base.

[0019]

As described in detail above, the wood-based vibration-isolating floorboard of the present invention has a three-layer laminate of non-woven fabric as the cushioning material, and the upper and lower layers are made of heat-bondable fibers having a thickness of 1.5 to 3 denier. Quantity 8
~24g / m ² of made and the nonwoven fabric, the intermediate layer thickness 6-3
Weight per unit area of 100 to 30 made of 0 denier thermoadhesive fiber
Since the nonwoven fabric is made of 0 g / m ² , the cut end surface can be sharply cut even when actual processing and cutting are performed with the cushioning material adhered to the wooden substrate, and the cushioning material is formed on the lower surface of the wooden substrate as in the past. It does not remain as fluff in the kerf or hole. Therefore, the luff of the cushioning material does not protrude from the end of the floor plate, and when the floor plate is laid, the luff does not become exposed on the surface as in the related art.

When the floorboard is laid on a floor base, the lower layer of the cushioning material is made of a nonwoven fabric having a basis weight of 8 to 24 g / m ^{2 made} of a thermoadhesive fiber having a thickness of 1.5 to 3 deniers. It is difficult for the adhesive to enter the cushioning material, the slip resistance between the adhesive and the floor base can be reduced, the floor boards can be laid on the floor base by sliding, and the workability can be improved.
