DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a floor material with a heater used as a floor in a house.

2. Description of the Related Art Conventionally, as a floor material with a heater, for example, a structure shown in FIG. 7 has been provided. That is, the lightweight cement layer 31 is formed on the plywood 30, the heater wire 32 is arranged in a meandering shape on the lightweight cement layer 31, both ends of the heater wire 32 are connected to electrodes, and the metal plate 33 and A floor material 36 with a heater is constructed by laminating a decorative sheet 35 after laminating a plywood 34. Floor material with heater 36
Are aligned by fitting the concave portions 37 and the convex portions 38 formed on the edges thereof, and are arranged on the joist tree 41 fixed on the supporting tree 39 by the nails 40 or the like.

According to the above conventional configuration, the heater wire arranged in a meandering shape.
There is a problem in that only the area around 32 is heated, that is, local heating occurs. Also, the heating action cannot be expected by breaking the heater wire 32 at one place. Therefore, when cut for adjustment with indoor dimensions, it cannot be used for heating.

To address this, for example, as disclosed in Japanese Patent Application Laid-Open No. 61-261567, there is provided a structure in which a floor heating panel is provided with a planar heating element and a decorative material is laminated on the surface.
However, in this case, the sheet heating element is expensive, and in order to reduce the amount of use, when a thin layer is to be laminated on the entire surface by, for example, coating using a roller or spraying, a faint portion (interrupted portion). Therefore, the entire surface cannot be heated properly.

The purpose of the present invention is to uniformly heat the entire surface,
Moreover, even if it is cut, the disconnection of the heater does not occur,
Further, the present invention is to provide a floor material with a heater that can always and smoothly pass an electric current and can be inexpensively constructed.

Means for Solving the Problems In order to achieve the above object, a floor material with a heater according to the present invention comprises a base plate formed by laminating a plurality of wooden veneers with their wood grains alternately intersecting each other. An inner thermosetting resin layer laminated along the unevenness of the wood grain on one surface of the base plate, and a direction which is disposed on the inner thermosetting resin layer and is orthogonal to the wood grain direction of the one surface of the base plate. And a pair of strip-shaped electrodes that are spaced apart in the wood grain direction and extend from the upper surfaces of both strip-shaped electrodes to the upper surface of the inner thermosetting resin layer and the entire exposed surface between both strip-shaped electrodes. And an outer thermosetting resin layer laminated on the heating element layer, and a decorative sheet laminated on the outer thermosetting resin layer.

According to the configuration of the present invention, the heating element layer can be laminated on one surface of the base plate by coating using a roller, spraying, or the like, and can be laminated with a small amount of use. At that time, one surface is uneven due to the grain and thin lamination causes, and in the convex portion, that is, in the direction orthogonal to the grain direction, a faint portion of the heating element layer is generated. However, the heating element layer portion is always located in the concave groove (recessed portion),
The continuity in the grain direction can be maintained. Further, the inner and outer thermosetting resin layers provide insulation and waterproofing to the strip electrodes and the heating element layer.

When a voltage is applied between the strip electrodes, a current flows through the entire heating element layer to generate heat, and the entire surface of the floor material is uniformly heated. At that time, even if the heating element layer has a faint portion, since the continuity in the grain direction is maintained in the heating element layer portion located in the concave groove, when a voltage is applied between the strip electrodes, The electric current always flows smoothly and surely along the grain direction. Also, for example, even if the current does not flow in a part of the area, the current flows in the remaining most of the area and heat is generated, and even when cut to a desired size, the heat is generated without any trouble. Be seen.

Embodiment An embodiment of the present invention will be described below with reference to FIGS.

Reference numeral 1 denotes a base plate, which is formed by laminating a plurality of single plates 2 so that their wood grain 2a is alternately orthogonal. At this time, a resin 3 such as an epoxy resin, a polyester resin, or a urethane resin is interposed between the wooden veneers 2. This resin 3 has no melting material and is not water-based, and is waterproof.
Heat-resistant and insect-proof materials are used, and organic mercury, tin, copper, etc. are added as chemical insecticides, and they can be cured at room temperature to eliminate the influence of moisture.
Further, the resin 3 is interposed so as to have an impregnated wall thickness of 0.1 to 0.5 mm, and serves as a waterproof skin and an adhesive as described above.

In the base plate 1 thus formed, the concave groove 4 is formed in one of the paired edge portions, and the convex strip 5 is formed in the other. A stepped through hole 6 having a small diameter portion 6a at the center and large diameter portions 6b and 6c at both ends is formed at a predetermined position of the base plate 1. An inner thermosetting resin layer 7 made of, for example, an epoxy resin is laminated on one surface (front surface) of the base plate 1 along the unevenness of the wood grain. Then, on the inner thermosetting resin layer 7, for example, a pair of strip electrodes 8 and 9 are arranged in the width direction of the base plate 1 and along the length direction. At this time, the strip electrodes 8 and 9 extend in a direction B orthogonal to the grain direction A on one surface of the base plate 1, are arranged at intervals in the grain direction A, and are fixed by adhesion.

Then, the strip electrodes 8 and 9 are connected to the lead wire via the connection fitting 10.
Connected to 11 and 12 round terminals 11a and 12a. This connection fitting 10
Is a mount member 13 fitted into the stepped through hole 6 from the front surface side, a pin 14 which can be driven into the mount member 13 from the front surface side, and a screw which is fitted to the pin 14 from the rear surface side.
It consists of fifteen. That is, the mount member 13 is composed of a tubular portion 13a housed in the small diameter portion 6a and a collar portion 13b housed in the large diameter portion 6b on the front surface side. An inclined recessed portion 13d that is open to the outside is formed.

The pin 14 includes an inner cylindrical portion 14a that can be fitted into the cylindrical portion 13a.
An annular convex portion 14 which is composed of a head portion 14b which can be fitted into the inclined concave portion 13d and which can be fitted into the annular concave portion 13c on the outer surface of the inner cylindrical portion 14a.
Along with forming c, a female screw hole 14d that opens on the back side is formed in the center. This pin 14 is a strip electrode 8,
The inner cylindrical portion 14a is passed through the holes 8a, 9a formed at the ends of the strip 9, and is driven into the mount member 13 to sandwich the strip electrodes 8, 9 between the head portion 14b and the collar portion 13b. The round terminals 11a, 12
The screw 15 that is passed through the a from below is an operating head 15b that holds the round terminals 11a and 12a between the threaded portion 15a that can be fitted in the female screw hole 14d and the back end of the mount member 13 and the pin 14. Consists of.

A heating element layer 16 is laminated from the upper surfaces of the two strip electrodes 8 and 9 to the upper surface of the inner thermosetting resin layer 7 and over the entire exposed surface between the two strip electrodes 8 and 9. The heating element layer 16 is formed of, for example, a film obtained by mixing powdery carbon, powdery conductive ore, powdery semiconductor ceramic, and resin. A heater 17 is formed by the strip electrodes 8 and 9 and the heating element layer 16.

Then, an outer thermosetting resin layer 18 made of, for example, an epoxy resin is laminated on the heating element layer 16, and a decorative sheet 19 is further laminated on the outer thermosetting resin layer 18. The decorative sheet 19 is made of, for example, a thin plate made of natural wood, a thin plate made of resin, or paper. The entire exposed surface of the laminated body including the base plate 1 and the decorative sheet 19 is covered with a skin layer 20 made of the same resin as the resin 3. Due to the above, floor material with heater 21
Is configured.

In manufacturing such a floor material 21 with a heater,
First, a stepped through hole 6 is formed at a predetermined position on a base plate 1 formed by laminating a plurality of single plates 2 with a resin 3 interposed between the single plates 2. Then, the inner thermosetting resin layer 7 is laminated on one surface of the base plate 1 by, for example, coating using a roller or spraying. At this time, since the inner thermosetting resin layer 7 is laminated along the irregularities of the wood grain 2a, it does not completely fill the concave groove of the wood grain 2a,
A similar groove (wood grain) remains. Then, the mount member 13 is fitted into the stepped through hole 6, and the inner thermosetting resin layer 7 is fixed as an adhesive.

Then, the strip electrodes 8 and 9 are arranged on the inner thermosetting resin layer 7 and fixed by adhesion or the like, and at this time, the holes 8
a and 9a are matched with the penetrating portion of the mount member 13, and are oriented so that the length direction is the direction B orthogonal to the grain direction A, and are arranged at intervals in the grain direction A. Next, insert the pin 14 into the inner cylindrical portion 14a of the hole 8
It is driven so as to pass through the tubular portion 13a from a and 9a. By this driving, the annular convex portion 14c is fitted into the annular concave portion 13c,
13, 14 are strongly coupled, and the inclined recess 13d and the head 14
The strip electrodes 8 and 9 are strongly sandwiched by d.

Then, the heating element layer 16 is laminated by coating or spraying from the upper surfaces of the strip electrodes 8 and 9 to the upper surface of the inner thermosetting resin layer 7 and the entire exposed surface between the strip electrodes 8 and 9. At that time, the heating element layer 16 is formed over the entire length in the above-mentioned concave groove. After the outer thermosetting resin layer 18 is laminated on the heating element layer 16 by coating or spraying, the decorative sheet 19 is laminated (laid) on the outer thermosetting resin layer 18. Next, base plate 1 and decorative sheet 19
An outer skin layer 20 made of a resin of the same quality as the resin 3 is formed on the entire exposed surface of the laminated body made of, for example, by coating or spraying.

The floor material 21 with a heater constructed in this manner is aligned on the joist 22 while fitting the groove 4 and the ridge 5 into each other. Then, the round terminals 11a and 12a located on the large diameter portion 6c on the rear surface side are screwed and fixed by the operating head portion 15b of the screw 15 by engaging the screw portion 15a with the female screw hole 14d. 2
3 is a support tree and 24 is a nail.

When using the floor material 21 with a heater, a predetermined voltage is applied between the strip electrodes 8 and 9 via the control device. Then, a current flows in the wood grain direction A throughout the heating element layer 16, and the entire surface of the heating element layer 16 generates heat. This heat is applied to the outer thermosetting resin layer 18, the decorative sheet 19, and the outer skin layer 20. Thus, the entire surface of the floor material 21 with a heater is uniformly heated. At this time, the thermosetting resin layers 7 and 18 on the inside and outside serve to insulate and waterproof the heater 17.

Further, the base plate 1 is also heated by the heat generation of the entire surface of the heating element layer 16. In this case, the resin 3 and the outer cover layer 20 cause the single plate 2 to be heated.
Since each is waterproof-sealed, the water content does not escape from the veneer 2. Even if the current does not flow in a part of the area due to some circumstances or failure during the use as described above, the current flows in the remaining most area and heat is generated. As a result, the entire surface is heated without any problem.

When arranging the floor material 21 with a heater indoors, adjustment with the indoor dimensions must be performed.In this case, the floor material 21 with a heater is desired in the longitudinal direction with both connecting metal fittings 10 left. Cut to size. At this time, the outer skin layer 20 described above is formed on the cut surface by coating.

Effect of the Invention According to the present invention having the above-described configuration, the heating element layer can be laminated on one surface of the base plate by coating using a roller, spraying, or the like, and the amount of the heating element layer can be reduced and the whole can be provided at low cost. At that time, one surface may be uneven due to the grain and thin lamination may cause the current to stop flowing in the faint portion generated in the heating element layer. The heating element layer portion is always positioned in the concave portion), and the continuous state in the grain direction can be maintained. Further, the inner and outer thermosetting resin layers can insulate and waterproof the strip electrodes and the heating element layer.

By applying a voltage between the strip electrodes, a current can be made to flow in the entire area of the heating element layer, and the heating element layer can generate heat.
The entire surface of the floor material can be uniformly heated, and local heating can be eliminated. At that time, even if there is a faint portion in the heating element layer, the heating element layer portion located in the groove can maintain the continuous state in the grain direction, and the current can flow in the grain direction at all times. The current can be smoothly and surely passed over the entire area. Furthermore, the desired heating action can always be expected even when cut to the desired size.
