Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soundproof flooring with a heating function.

[0002]

2. Description of the Related Art Conventionally, as a floor material with a heating function used in an apartment house, a floor heating heat panel in which a heating means is buried on the back side of a surface material has been used. Such a floor heating heat panel is disclosed in Japanese Unexamined Patent Publication No. 10-27442.
As shown in Japanese Patent Publication No. 0, a sheet-like PTC heater (synonymous with “PTC thermistor” described later) is provided along the back surface of the panel body, and one electrode of the PTC heater is connected to a power supply cord. The connection cord is provided so as to be in contact with the heating surface of the PTC heater.

[0003] However, when connecting the electrode and the power cord, the wire is partially peeled off and directly connected to the PTC heater, so that it takes time and effort to manufacture the heat panel, and safety such as waterproofness is required. There was a problem of lack of reliability in terms of sex.

[0004] The above-mentioned problem is solved by connecting the heat panels with a connector composed of an outlet and a plug. However, when the connector is provided on the panel surface, a heater cannot be provided at that portion, and the panel surface is not provided. When the temperature is not uniform and the adjacent panels are connected to the side via connectors, the connection positions of the adjacent panels are fixed, and there is a problem that it is difficult to absorb the displacement during floor construction. .

[0005]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems, is easy to manufacture, is excellent in safety such as waterproofness, and has no temperature difference on the floor surface, so that there is a slight shift during floor construction. It is an object of the present invention to provide a sound-insulating flooring material with a heat-heating function, which can absorb heat and has good soundproofing performance.

[0006]

According to the first aspect of the present invention, a sound-insulating flooring with a heating function (hereinafter referred to as "floor of the present invention") comprises a hard plate, a flat heating element, From the power supply side, on the side surface of the hard resin foam, of the floor material in which the hard resin foam is provided with a plurality of floor laminates laminated in this order,
A connector for distributing and supplying electricity to the flat heating element of the floor laminate and the flat heating element of the adjacent floor laminate is housed, and the connector of the adjacent floor laminate is connected by a cable. What is connected.

[0007] The sound-insulating flooring with heating function of the present invention, as described in claim 2, has a structure in which the side of the hard resin foam of the flooring is provided with:
It is preferable that a housing for housing the cable wiring is provided.

The hard plate used in the present invention is:
The material is not particularly limited as long as it does not easily break or be damaged by the load normally applied to the flooring material. For example, wood materials such as wood veneer, plywood, particle board, high-density fiber board, and medium-density fiber board Thermoplastic resins such as polyethylene, polypropylene, polyvinyl chloride and the like; thermosetting resins such as polyester and epoxy resin; and laminates of these; HDF, MDF in terms of soundproofing, processability and texture.
Etc. are preferred.

A surface decorative material such as a veneer, a synthetic resin or a synthetic resin foam sheet, a decorative paper, a synthetic resin impregnated sheet, etc. is adhered and laminated on the hard plate-like body as required. It may be added in a tone. In this case, it is preferable to bond and laminate both surfaces of the hard plate to prevent warping. Further, printing, painting, coloring, coating, and the like may be performed in order to impart designability, woody feel, scratch resistance, and the like.

[0010] The hard plate-shaped body may be provided with a process for a conventionally known joining method, such as a claw or a chip, on the whole or a part of the periphery thereof.

If the thickness of the hard plate is too thin, it is easily broken when walking or placing a heavy object, and if it is too thick, the soundproofing property is reduced.

The flat heating element used in the present invention is not particularly limited. For example, a heating element in which nichrome wires are arranged in a flat plate shape may be used. However, carbon fiber or powder is hardened with resin, cement or the like. A planar heating element such as a heating element or a titanic acid-based heating element is preferable in that the floor heating can be performed uniformly, and the planar heating element has a resistance value with a rise in temperature as described in claim 3. Temperture Coeffi-cient Thermis
tor: hereinafter referred to as “PTC thermistor”), because it is possible to prevent burns or the like due to local abnormal heat generation.

The thickness of the flat heating element is not particularly limited. However, if the thickness is too large, the bending rigidity of the heating element increases, and the sound insulation performance of the obtained flooring material cannot be sufficiently obtained. Preferably, it is 1 mm or less.

The hard resin foam used in the present invention is not particularly limited as long as it is excellent in soundproofing and high in bending rigidity.
Double rigid polyurethane foam, polystyrene foam having a magnification of 10 to 30 times, and the like.
No. 38091, wherein a thermoplastic resin foam is a continuous foam layer made of a thermoplastic resin, a high foam body made of a thermoplastic resin arranged on at least one surface of the continuous foam layer, and an outer surface of the high foam body A low-foaming thin film made of a thermoplastic resin covering the thermoplastic resin foam, wherein the plurality of high-foaming materials are heat-sealed to each other via the low-foaming thin film to provide soundproofing and bending rigidity. It is particularly preferable because it is excellent.

In the present invention, if necessary, a soft resin foam may be further laminated on the back surface of the hard resin foam in order to cope with irregularities. The soft resin foam is not particularly limited as long as it has a relatively low compression modulus relative to the hard resin foam. For example, a polyethylene foam having an expansion ratio of 10 to 30 times, and a foaming ratio of 20
Polyurethane foam of up to 40 times is mentioned.

The hard resin foam and the soft resin foam may be provided with a groove or a groove to further improve the soundproofing property as required or to cope with unevenness of the adherend (generally, concrete). Irregularities may be applied.

(Action) The sound-insulating flooring material with a heating function of the present invention comprises:
From the surface side, a hard plate-like body, a flat heating element, and a floor material formed by arranging a plurality of floor laminates in which the hard resin foam is laminated in this order, on the side surface of the hard resin foam, From the power supply side, a flat heating element of the floor laminate and a connector for distributing and supplying electricity to the flat heating element of the adjacent floor laminate are housed, and connectors of the adjacent floor laminate are housed. Are connected by cable wiring, making them easy to manufacture, and since electricity is distributed and supplied inside the connector, it is excellent in safety such as waterproofness, and a heater is installed on almost the entire floor surface Because there is no temperature difference on the floor surface, the connectors are connected by cable wiring, so it can absorb some misalignment during floor construction, and the hard resin foam absorbs the impact sound, so the soundproof performance It will be excellent.

In the present invention, if the housing for accommodating the cable wiring is provided on the side surface of the hard resin foam, the degree of freedom of the arrangement position of the connector is increased, and the cable wiring is provided in a place where it can be visually recognized. There is no exposure.
