In addition, in the present embodiment, the connection of each exothermic coating 6 is shown via the connection fittings 8 and 8a and the conductors 9 and 9a. However, the connection of each exothermic coating 6 is not limited to this method. Contact may be made or connection may be made by adhesion using a conductive adhesive, and the heat generating material 1 may be appropriately used depending on the amount of heat generated by the heat generating coating 6 for construction.

Further, in order to find a defective portion of the heat generating material 1, a paint which emits light or changes color due to temperature change may be applied to the entire surface of the heat generating material 1.

Next, the use of the roof material 2 or the interior / exterior material 3 using the heat generating material 1 will be described. First, the roof material 2 is formed by sintering as a cold-resistant tile base material, and is made of clay sintered with thermal conductivity. In the same manner as described above, the heat-generating coating 6 and the insulating coating 7 are attached to the heat-generating material 1 on the front surface 4 or the back surface 5 of the side tiles such as the roof tiles, eaves tiles, sleeve tiles, etc.

Next, a fine powdery organic substance such as sawdust is appropriately added to the ceramic raw material in the ceramic raw material used as a floor material, wall material, etc. that can be laid in a showcase for displaying indoors, cultural assets, food products, products, etc. A material having a moisture absorbing / releasing property such as a material which is added in a ratio, pulverized, kneaded and molded, and then dried and fired to form a porous material is used as the inner and outer material 3, and the surface 4 of the inner and outer material 3 is formed. The heat generating film 6 and the insulating film 7 are attached to the rear surface 5 and the back surface 5 to form the heat generating material 1 as described above.

It is also possible to attach the heat-generating coating 6 and the insulating coating 7 to the tiles 10 used as flooring and wall materials.

[Effect of device]

In short, the present invention applies a heat-generating coating by applying a mixed liquid containing a metal / ceramic composite material having conductivity and heat generation due to energization to the front surface 4 or the back surface 5 of the roof material 2 or the interior / exterior material 3 made of a clay sintered body. Since the heat generating film 6 is formed, the heat generating film 6 can be made to generate heat by energizing the heat generating film 6 through the conductors 9 and 9a and the connection fittings 8 and 8a with a DC or AC power source. Since it can be used, the use as the heat generating material 1 has a wide range as will be described later, and the manufacturing process is relatively simple, mass production is possible, and the construction can be easily performed and the construction cost can be reduced. I can.

Further, when the heat generating material 1 is a roof tile or the like that is the roof tile 2, the heat generating material 1 made of a clay sintered body having a high thermal conductivity is heated by the heat generating coating 6 to raise the temperature of the entire inside thereof. By releasing the internal moisture, the clay sintered body is a porous solid, so that the mixed liquid containing the metal-ceramic composite material penetrates into the pores to increase the adhesion area. Since the adhesion between the base material such as a roof tile and the coating is good, it is possible to prevent problems such as deterioration and peeling of the coating due to natural conditions such as freezing.Because the coating contains ceramic, Has a coefficient of thermal expansion similar to that of the clay sintered body, and because of the good adhesiveness, it is possible to maintain the bonding state with the base material even when heat is generated, so the roof is used under severe natural conditions. It can be used more than 2 and therefore can be used with snow melting roof tiles when snow is accumulated. In particular, the heating film 6 is attached to the sloping roof eaves 14 and the heating film 6 is heated to heat the drips 14. Thus, it is possible to prevent icicles from being formed at the lower end of the drip 14, and to prevent damage to the house caused by the icicles, or injury such as personal injury due to falling of the icicles.

In the case of the interior / exterior material 3 which is a floor material and a wall material,
Since the interior of the room can be uniformly heated by the radiation effect of the heat generating material 1, the air in the room is not polluted and it is hygienic and the room can be widely used.

Further, when the floor material and the wall material are tiles 10, the above-mentioned effects are exhibited, and the heat generating material 1 can be laid in a place handling water such as a bathroom or a toilet.
