BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of an overlaid floor heating panel according to the present invention; FIG. An upper floor heating panel (hereinafter, referred to as a floor heating panel) A is formed by, for example, forming a long plate 2, 2... 12 mm thick, 75 mm wide and 2400 mm long by a flexible back member 3. Multiple sheets in the horizontal direction (24 sheets in this embodiment)
A floor heating panel main body 1 (hereinafter referred to as a panel main body) configured to be connected and windable (refer to FIG. 4) is provided, and left and right ends of the panel main body 1 in the same direction as the long plate piece 2 are provided. ,
Vertical edge members 4, 4 tapered outward are attached.

Each of the long plate pieces 2 has an embedding groove 5 whose back surface is opened at substantially the center thereof, and the embedding groove 5 has a crosslinked polyethylene as a heating fluid conduit. Hot water pipe 6 is buried, and this hot water pipe 6
Is supplied with hot water from a heat source unit (not shown) and is circulated through substantially the entire panel body 1.

Each of the long plate pieces 2 is composed of a resin molded plate 2A and a decorative surface plate 2B adhered to the surface of the resin molded plate 2A.
It is composed of The resin molded plate 2A is a resin molded product (also made of recycled wood) obtained by kneading a chip-shaped wood chip (including sawdust) and a metal powder such as aluminum as a high thermal conductor into a resin serving as a base and hot pressing. ), And the resin as a base is polypropylene (P
P), acrylonitrile butadiene styrene (AB
S) and the like are desirable, and the surface decorative board 2B uses a thin sheet of natural wood, a resin sheet with a wood grain pattern, or the like.

As shown in FIG. 2 and FIG. 3, on each of the left and right end surfaces in the width direction of each of the long plate pieces 2, there is a wavy male-side uneven portion X on one side and the same wavy portion on the other side. The female side uneven portion Y is provided, respectively, and the one vertical edge member 4 is provided.
A female-side uneven portion Y is provided on one end surface portion in the width direction of
With the male and female side uneven portions X and Y, the long plate pieces 2 and the long plate piece 2 and the vertical edge member 4 are unevenly fitted to each other.

A back member 3 is adhered to substantially the entire back surface of the panel body 1, and the long plate pieces 2 and the vertical edge members 4 are connected by the back member 3 so as to be wound. I have.
The back member 3 is composed of a heat equalizing sheet 9 made of aluminum foil, a part of which is in contact with the hot water pipe 6, and a nonwoven fabric 10 bonded to the outside of the heat equalizing sheet 9.

At both upper and lower ends of the panel body 1 in a direction orthogonal to the long plate 2, there are attached lateral edge members 12, which are also tapered outward. These horizontal edge members 12 are attached in a state where the panel main body 1 is spread in a flat plate shape, and are spliced by uneven fitting to the long plate pieces 2 like the vertical edge members 4. It is a structure, and is screwed to the vertical edge member 4 using the fixing metal fittings 14 and 14 shown in FIG. 4 when the floor heating panel A is installed, together with the tapered corner members 13 and 13 arranged at the four corners.

Reference numeral 15 denotes a connecting portion cover attached to one of the side edge members 12. The connecting portion cover 15 connects the hot water pipe 6 to the forward / return hot water pipes 16, 16 connected thereto. Cover the part. The other end of the hot water pipe 16 is connected to an outdoor heat source device via a hot water outlet (not shown) attached to an indoor wall or the like.

FIG. 4 is an explanatory view for explaining a wound state of the panel main body 1 when the floor heating panel A is packed or housed. The panel main body 1 including the vertical edge member 4 is as shown in FIG. , Rolled up, the side edge material 12, the corner material 1
3 and the fixture 14 are separated from the panel body 1,
Put in the packing box.

When the floor heating panel A is installed, the wound panel body 1 as shown in FIG. 4 is spread on a floor such as a flooring with the back member 3 down, and then the panel body 1 Attach the corner members 13, 13 at the four corners between the horizontal edge member 12 and the vertical edge member 4,
The horizontal edge member 12 and the corner member 13 are screwed and fixed to the vertical edge member 4 using the fixing brackets 14, 14. And hot water piping 16
Connect a plug (not shown) provided at the end of the device to a hot water outlet.

According to the present embodiment, the hot water pipe 6 is buried in the burying groove 5 formed substantially at the center of the back surface of each long plate piece 2, so that the long plate piece 2 itself has the front surface. It can be used by laying it on the floor such as the flooring of an existing house, and it is not only excellent in workability but also each of the long plate pieces 2.
Is a resin molded plate 2A containing chip-shaped wood dust (including sawdust) and a metal powder such as aluminum as a high thermal conductor, and a decorative surface plate 2B attached to the surface of the resin molded plate 2A. , The resin molded plate 2A
The heat from the hot water pipe 6 is satisfactorily and widely transmitted to the surface side of each of the long plate pieces 2 via the metal powder contained in the metal powder, thereby promoting the heat conduction of each long plate piece 2 itself. In addition to this, there is no fear that the long plate piece 2 is cracked by the influence of the heat from the hot water pipe 6, and the durability can be improved.

Further, since the panel main body 1 has a configuration in which a plurality of long plate pieces 2 and 2 arranged in a row are connected by a flexible back member 3 so as to be able to be wound, the panel body 1 can be used at the time of packing or the like. The panel body 1 can be folded and compactly packed.

In the embodiment described above, the hot water pipe 6 made of cross-linked polyethylene as the heating fluid conduit is buried in the burying groove 5, but a heating wire is buried instead of the hot water pipe 6. Is also good.

[0021]

Since the present invention is constructed as described above, it can be used by laying it on a floor such as a flooring of an existing house without impairing the basic tone of the room floor, and is not only excellent in workability, Since the heat conduction of the panel body itself is enhanced,
The heat from the heating fluid conduit or the heating wire can be transmitted to the surface of the panel body satisfactorily and over a wide area, and the heat radiation can be improved. Cracking can be prevented,
The durability is improved.
