Furthermore, in the case of a structure built inside a building, the indoor heating efficiency can be improved.

Hereinafter, an embodiment in which the present invention is embodied as a snow melting structure of a road as an outdoor structure will be described with reference to FIGS.
As shown in FIG. 1, on the surface 11a of the road 11 made of concrete C, slit-shaped accommodation grooves 11b are formed in parallel to each other at a plurality of locations so as to be directed downward by a rotary blade of a road cutter (not shown). The electrothermal sheet 12 is accommodated in the orthogonal direction in each accommodation groove 11b. As shown in FIG. 2, mortar 13 as a joint material is formed in a gap formed between the left and right inner side surfaces 11c, 11d of the housing groove 11b and the left and right side surfaces 12a, 12b of the electric heating sheet 12. The electric heating sheet 12 is filled and fixed in the accommodation groove 11 b by the mortar 13.

Next, a method for manufacturing the electric heating sheet 12 will be described with reference to FIGS.
When the electric heating sheet 12 is manufactured, a first film 14 and a second film 18 made of a strip-shaped laminate film are prepared. As shown in FIG. 3A, the first film 14 is formed by a film main body 15 made of an insulating material and an adhesive layer 16 preliminarily applied to the entire upper surface of the film main body 15. On the upper surface of the adhesive layer 16, a strip-shaped thin-film electrothermal layer 17 made of a heat-generating paint is adhered except for the left and right side portions in the width direction.

  As shown in FIG. 3B, the second film 18 includes a film main body 19 made of an insulating material like the first film 14, and an adhesive layer 20 preliminarily applied to the entire upper surface of the film main body 19. It is formed by. On the upper surface of the adhesive layer 20, a pair of left and right electrode strips 21, 22 made of copper foil tape with a predetermined interval in the width direction of the film body 19 and excluding both left and right ends in the width direction of the film body 19. Is glued.

  As the laminate film, for example, a product name “CP-roll” of a roll type film manufactured by Fuji Pla Co., Ltd. (Ginza 1-9-7 Yamato Building, Chuo-ku, Tokyo) has a thickness dimension of 150 microns, a width of 310 mm, and a length of 50 m. Things are used. Further, as the copper foil tape, for example, a conductive copper foil tape manufactured by Teraoka Seisakusho is used, and the thickness dimension is 0.07 mm, the width dimension is 6 mm, and the length dimension is 20 m. As the exothermic paint for forming the strip-shaped thin film electrothermal layer 17, a one-pack type room temperature dry paint or a room temperature dry solvent-based paint added to graphite is used. A conductive paint may be used in place of the copper foil tape. As this conductive paint, an emulsion type water-soluble paint or a one-pack type room temperature dry paint is added to graphite.

  As shown in FIG. 4, the first film 14 provided with the belt-like thin film electrothermal layer 17 and the second film 18 provided with the electrode belts 21 and 22 are wound around a bobbin 23 in a roll shape and used for a pair of upper and lower contacts. As shown in FIG. 5, the electrode strips 21 and 22 are overlapped on the left and right upper surfaces of the strip-shaped thin film electrothermal layer 17 by a roller 24. In this state, the toner is supplied between a pair of upper and lower heating and fusing rollers 25 shown in FIG. Then, as shown in FIG. 6, the adhesive layers 16 and 20 are heated and fused to each other by both rollers 25, and the left and right side portions of the film body 15 and the film body 19 are joined to each other by heat fusion. . Moreover, the film main bodies 15 and 19 and the strip-shaped thin-film electrothermal layer 17 positioned between the electrode strips 21 and 22 are fused by the heated adhesive layers 16 and 20, and the integrated electrothermal sheet 12 is manufactured.

  The electric heating sheet 12 manufactured in this way is wound up on a winding bobbin 26 shown in FIG. As shown in FIG. 6, the electric heating sheet 12 has a width W dimension of 310 mm and a thickness t dimension of 0.5 mm, and is flexible so that it can be easily deformed.

  As shown in FIG. 4, the electric heating sheet 12 wound around the bobbin 26 is cut into a predetermined length and then applied to the accommodation groove 11 b of the road 11 as shown in FIGS. 1 and 2. A voltage of, for example, 6 to 24 volts, preferably 12 volts is supplied to both electrode strips 21 and 22 of each electric heating sheet 12 from a power source (not shown) using a conductive wire, and the strip-shaped thin film heating layer 17 generates heat. This heat is conducted to the concrete C in the vicinity of the surface 11a of the road 11, and the concrete C is heated, and the snow on the surface 11a of the road 11 is melted by this heat.

  As shown in FIG. 2, the depth d of the accommodation groove 11 b of the road 11 is 320 mm so as to be slightly larger than the width W of the electric heating sheet 12. Moreover, the horizontal gap T dimension of the accommodation groove 11b is set to, for example, 2 to 5 mm so as to be larger than the thickness t dimension of the electric heating sheet 12. The width W dimension of the electric heating sheet 12 is set to 20 mm to 60 mm. The reason for this is that if the depth is 60 mm or more, the depth d dimension of the accommodation groove 11b formed in the concrete C is increased and the strength of the concrete C is reduced, and the forming operation of the accommodation groove 11b is difficult. This is because a short circuit between the electrode bands 21 and 22 may occur.

  Since the electric heating sheet 12 is formed to have a thin thickness t, for example, when it is used in a place where mechanical strength is required, such as a road with a large vibration when the vehicle travels, as shown in FIG. Further, it is desirable that the electrothermal sheet 12 is entirely covered with a protective cover 28 made of fiber reinforced plastics (FRP).

For this reason, it is not necessary to form a housing recess for housing the electric heating sheet 12 over a large area on the surface of the road 11, and it is not necessary to refill the wide housing recess. It can be done easily.

  (2) In the above embodiment, since the electric heating sheet 12 is embedded in the accommodating groove 11b in the orthogonal direction, the direction of heat conduction from the electric heating sheet 12 to the concrete C is horizontal, that is, parallel to the surface 11a. Therefore, useless heat conducted downward from the surface 11a of the road 11 to the inside can be suppressed, and the snow melting efficiency of the surface 11a can be improved.

  (3) In the above embodiment, since the deformable electric heating sheet 12 is accommodated in the accommodation groove 11b, the accommodation operation of the electric heating sheet 12 in the accommodation groove 11b having a small gap T dimension can be easily performed. .

  (4) In the said embodiment, since the 1st film 14 and the 2nd film 18 were joined and the strip | belt-shaped thin film electrothermal layer 17 and the electrode strips 21 and 22 were pinched | interposed by both films, The thickness t dimension can be reduced. For this reason, the clearance gap T dimension of the accommodation groove | channel 11b of the road 11 can be made small, the usage-amount of the mortar 13 can be decreased, and material cost can be reduced.

Next, another embodiment of the electric heating sheet 12 will be described with reference to FIGS. 8 and 9.
In the electric heating sheet 12, the width W dimension of the first film 14 and the second film 18 is selected from the range of, for example, 20 to 60 cm. As shown in FIG. 8, the strip-shaped thin-film electrothermal layer 17 and the electrode strips 21 and 22 are sandwiched in parallel at a plurality (7 in this embodiment).
