DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden surface material and a soundproof and shock-absorbing material provided on the back surface thereof for suppressing the transmission of sound due to a weight impact and absorbing the impact when exercising on the floor. The present invention relates to a floor heating floor material composed of materials.

[0002]

2. Description of the Related Art Recently, floor heating panels have been laid on floors of medical and welfare facilities, gymnasium floors, or general household floors. In this case, in the welfare facilities, to prevent fractures due to the fall of the elderly, in the gymnasium, to absorb the impact of intense exercise, and in ordinary households, to absorb the impact sound of the upper floors In addition, a device provided with a soundproof and cushioning material made of a nonwoven fabric or the like is known.

[0003]

However, the soundproofing and cushioning material made of nonwoven fabric, foamed urethane, etc. is excellent in soundproofing and cushioning, but also excellent in heat insulation. For this reason, if the soundproofing and cushioning material is used, there is a problem that heat transfer efficiency is reduced and it takes time to increase the surface temperature of the wooden surface material.

Therefore, it is conceivable to transfer the heat of the floor heating panel to the wood-based surface material by using aluminum foil or other metal foil having good thermal conductivity.

[0005] However, when the wooden surface material and the soundproofing / buffering material are applied to the wooden surface material on the surface on which the metal foil is applied so as to be integrated, the wooden surface material is thermally expanded by the aluminum foil. The problem of warpage occurs.

[0006] It is an object of the present invention to provide a floor material for floor heating in which such a problem is solved.

[0007]

According to the present invention, in order to achieve the above object, according to the present invention, a floor laid on a floor heating panel is formed by combining a plurality of long floor materials. Make up,
In the floor material composed of a wood-based surface material and a soundproof and cushioning material made of a nonwoven fabric provided on the back surface thereof,
An aluminum foil or other metal foil is provided on the upper and lower surfaces of the soundproofing / buffering material, and the metal foils located on the upper and lower surfaces of the soundproofing / buffering material are continuous at least in part, and at least the wood-based material is used. The metal foil on the upper surface to be adhered to the surface material is characterized by having a number of slits perpendicular to the longitudinal direction of the soundproofing and cushioning material.By providing such a configuration, even if the metal foil extends in the longitudinal direction due to heat. Since this can be divided at the slit portion, it is possible to solve the problem that the wooden surface material is warped due to the extension of the metal foil.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. The embodiment shown in the drawings will be described. In the drawings, reference numeral 1 denotes a floor heating panel constructed by fitting a hot water pipe 1a into a rubber chip panel or the like composed of rubber chips and wood chips; 2 denotes a floor laid on the floor heating panel 1; And long floor materials 3 are combined. The flooring material 3 is composed of a wood-based surface material 4 and a soundproofing / buffering material 5 made of a non-woven fabric or the like provided on the back surface thereof.

As described above, the soundproofing / buffering material 5 is excellent in soundproofing and cushioning, but also excellent in heat insulation. Therefore, the presence of the soundproofing and cushioning material 5 lowers the heat transfer efficiency,
There is a problem that it takes time to raise the surface temperature of the wood-based surface material 4. Therefore, aluminum foil, copper foil or other metal foil 6 having good heat conductivity is provided on the upper and lower surfaces of the soundproofing / buffering material 5, and the metal foil 6 transfers heat from the floor heating panel 1 to a wood-based material. It was transmitted to the surface material 4.

Then, in order to integrate the wooden surface material 4 and the soundproofing / buffer material 5, the metal foil 6 must be bonded to the back surface of the wooden surface material 4 and the soundproofing / buffer material 5. ,
Due to the elongation of the metal foil 6 due to thermal expansion, the wood-based surface material 4 is warped.

In view of this, a large number of slits 7 are provided in the metal foil 6 on the upper surface to be adhered to the wood-based surface material 4 so as to be orthogonal to the longitudinal direction of the floor material 3.

The metal foil 6 has a thickness of 5 μm to 75 μm.
The metal foil 6 provided on the upper and lower surfaces of the soundproofing / buffering material 5 was made continuous at least in part using aluminum foil of a degree. To explain this, in the thing shown in FIG. 3, the metal foil 6 was wound so as to extend along the side surface from the lower surface of the soundproofing / buffering material 5 and face the upper surface.

However, as shown in FIG. 4, both ends of the metal foil 6 overlap on both sides from the lower surface of the soundproofing / buffering material 5 on the upper surface of the soundproofing / buffering material 5, in other words, the floor heating is performed by the metal foil 6. It may be provided so as to surround the soundproofing / buffer material 4.

In this case, the elongation in the longitudinal direction due to the thermal expansion of the metal foil 6 can be divided by the slit 7, and the warp of the wood-based surface material 4 accompanying the elongation of the metal foil 6 can be eliminated.

A large number of grooves 4a perpendicular to the longitudinal direction are also provided on the back surface of the wood-based surface material 4 to prevent the wood-based surface material 4 itself from warping due to thermal expansion.

Reference numeral 4b denotes a groove provided along one side surface in the longitudinal direction and one side surface in the width direction of the wooden surface material 4, and 4c denotes a groove in the other side surface in the longitudinal direction of the wooden surface material 4 in the width direction. The tenon provided on the other side surface is shown, and the tenon 4c is sequentially inserted into the groove 4b to lay the floor 2 on the floor heating panel 1.

Further, it is more preferable that a large number of slits 7 orthogonal to the longitudinal direction of the floor material 3 are provided not only on the metal foil 6 on the upper surface of the soundproofing / buffering material 5 but also on the metal foil 6 on the lower surface.

[0018]

As described above, according to the first aspect of the present invention, the heat from the floor heating panel is transmitted to the wood-based surface material by the continuous metal foil applied to the upper and lower surfaces of the soundproofing and cushioning material. And the time required for the temperature of the wooden surface material 4 to rise can be increased, and even if the metal foil may expand in the longitudinal direction due to thermal expansion, the elongation is cut by a slit provided in the metal foil. And the problem that the surface material is warped due to the extension of the metal foil can be eliminated.
