[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite floor for use in a building flooring where heat transfer performance is required in addition to sound and vibration proofing properties. composite material for a mat with one member, in particular when forming the flooring on floor heating mat, a composite flooring material and one member of the thermally conductive fiber mat.

[0002]

For example, in a conventional floor heating structure, a floor material comprising an upper surface material, a base plate and a lower fiber mat is laid on a floor heating mat having an electric heating means and a hot water passing means. It is known to provide soundproofing in addition to the heating function.

[0003] The fiber mat is inevitable in exhibiting soundproofing and vibration-proofing properties, but on the other hand, heat is transmitted from the floor heating mat to the floor surface due to the presence of a large amount of air and heat insulation. Efficiency is very poor.

The present invention has been made in view of the above-mentioned problems of the prior art, and has been completed as a result of intensive studies. A heat conductive fiber in which the fiber mat has improved heat conductivity without impairing the soundproofing and vibrationproofing properties. It is to provide a composite floor material having a mat as one member.

BEST MODE FOR CARRYING OUT THE INVENTION The thermally conductive fiber mat according to the present invention is composed of an inorganic fiber including organic fibers and metallic fibers, or a fibrous nonwoven fabric mat made of a blend thereof. Fibers containing pressure-resistant fibers rich in rebound resilience and entangled fibers bridging between the pressure-resistant fibers can be employed. The nonwoven fabric mat may be wrapped with a resin sheet or cloth sheet for the purpose of preventing shape loss and moisture absorption as required.

Although the ordinary fiber mat itself inhibits heat transfer as described above, the heat conductive fiber mat of the present invention is used in the fiber mat to improve heat transfer. Fibers, for example, metal fibers, ceramic fibers, etc. are used for part or all of the fiber material,
Further, a heat conductive powder or a far-infrared radiation powder, such as a metal foil or a ceramic flake, may be mixed. In the present invention, a heat conductive sheet is attached to one or both surfaces of the fiber mat in order to more effectively exhibit heat transfer performance.

[0008] The heat conductive fiber mat is placed on the lower layer,
If a plate made of a base plate is arranged at a higher position and integrated to form a floor material as a composite material, the floor material can be laid on a floor heating mat to complete a suitable floor heating system.

As the floor heating mat, a foamed resin mat or a fiber mat having a built-in heating means such as an electric heating means or a hot water passing means is employed. For example, polyolefin having an expansion ratio of 30 to 50 times,
It is formed by using a polystyrene or urethane-based resin, and arranging a hot water pipe therethrough. Alternatively, a design can be made such that a heat conductive metal sheet such as an aluminum foil is attached to the surface of the mat so that heat transfer is good and uniform.

[0010] In the floor material comprising the surface material, the base plate, and the thermally conductive fiber mat, the surface material, for example, the veneer has a thickness of 0.2 mm.
It is made of thinly sliced precious wood of ~ 0.3mm to less than 2mm, and is usually attached to a plywood base plate to give the floor surface the unique aesthetic appeal of wooden floors. However, in a severe environment such as a case where a floor heating mat is provided below and forcibly heated, the veneer is likely to crack or warp.
In order to suppress the above-mentioned problems, a plurality of, preferably three or more layers of wood thin plates having a thickness of less than 2 mm similar to the veneer are laminated with different orientation directions of their fibers, and further, the upper layer is formed on the upper layer. It is desirable to form a surface layer material having a thickness of about 2 to 3 mm by sticking and integrating a veneer plate in a different orientation direction of the fibers.

The bedboard is usually composed of three or more layers, for example, five to seven layers of wood plywood. Although the thickness is not specified, it can be appropriately set in the range of 5 to 12 mm. As a means of imparting sound and vibration proof properties to the base plate, after attaching the base plate to the surface material, a large number of Carve a slit. The slits can be formed arbitrarily, such as those parallel to the width direction of the plate or those parallel to the longitudinal direction of the plate, and the slit interval can be arbitrarily designed such as 10 mm to 100 mm.

In the present invention, the thermally conductive fiber mat which is disposed below the base plate and is joined to and integrated with the base plate is made of organic and / or inorganic fibers as described above. Adopt heat conductive fiber or far infrared radiation fiber, such as metal fiber, ceramic fiber, etc. for a part or all of the fiber material, and also use heat conductive powder material or far infrared radiation powder material, such as metal foil or Ceramic flakes and the like can be mixed. In order for the heat conductive fiber mat to exhibit heat transfer performance more effectively, it is essential to attach a heat conductive sheet, for example, an aluminum foil sheet, to one or both surfaces of the fiber mat. The thickness of the heat conductive fiber mat is not limited, but is, for example, about 3 mm to 10 mm.

When the heat conductive fiber mat and the floor heating mat are in direct contact with each other, there is a case where the floor mat increases during walking or the like due to the flexibility of the fiber mat. A discard material may be interposed between the floor heating mat and the floor heating mat as appropriate.

By adopting the above-described structure, it is possible to maintain the sound insulation performance of the sound insulation class LL45 or less, and of course, remarkably promote the transfer of heat to the floor surface when the floor heating mat is heated as compared with the prior art. Can be.

A specific example will be described below with reference to the accompanying drawings. FIG. 1 is a partially exploded perspective view of a floor heating structure showing a specific example according to the present invention. Reference numeral 1 denotes a surface layer material, which is formed by laminating and sticking a veneer plate and a three-layered thin wooden plate thereunder in different orientations of fibers with respect to each other, in this specific example.
The surface layer thickness is 2.5mm.

Reference numeral 2 denotes a base plate made of wood plywood. In this embodiment, five layers of veneers are laminated and adhered to each other in different orientations of the fibers, and have a thickness of 6 mm. After the surface plate 1 and the base plate 2 are adhered to each other, the slits 3 are formed over substantially the entire thickness of the base plate 2. The slit interval is, for example, 12 mm.

Below the base plate 2, for example, a thickness of 4 mm and a density of 12
A thermally conductive fiber mat 4 mainly composed of a nonwoven fabric mat 5 of 0 g / m ³ to 1.6 kg / m ³ is provided. As described above, the nonwoven fabric mat 5 can employ a thermally conductive metal fiber or a far-infrared radiating ceramic fiber for a part or all of the fiber material, and a heat conductive metal foil piece or a far-infrared radiating ceramic flake. It can be mixed. Non-woven mat 5
Has aluminum foil sheets 7, 7 'having excellent thermal conductivity attached to the lower surface or the upper surface thereof. Although there is no particular limitation on the attaching means, for example, a means such as stitching the aluminum foil sheet and the nonwoven fabric mat using a needle punch, or bonding the aluminum foil sheet and the nonwoven fabric mat with a hot melt adhesive is used. The floor material 6 is formed by integrally integrating the surface material 1, the base plate 2, and the thermally conductive fiber mat 4.

Below the thermally conductive fiber mat 4 to which the aluminum foil sheet 7 is attached, a piling material 8 made of, for example, plywood is provided as needed. As described above, when the floor heating mat 9 is disposed immediately below the thermally conductive fiber mat 4, there is a case where the floor sinks during walking or the like due to an increase in cushioning property due to both mats.
The harmful effect can be suppressed by interposing the above-mentioned waste material 8 therebetween, and when the floor material 6 is peeled and removed in order to maintain and check the heating function of the floor heating mat 9, the waste material 8 is removed. With the interposition, the floor heating mat 9 can be prevented from being damaged and can be easily separated.

Below the waste material 8, for example, a density of 150 kg /

Arrange 12

With the above construction, the flooring material according to the present invention can maintain the sound insulation function at a sound insulation grade of about LL45, and can significantly improve the heat transfer to the floor surface as compared with the conventional case. Can be.
