  2. Description of the Related Art A floor heating structure in which a floor heating mat in which hot water piping is routed in a groove on the upper surface of a plate-like substrate is laid on the floor is well known.

  As this floor heating mat, a foldable one has been put into practical use. By folding the floor heating mat, the handleability and workability during transportation and the like are improved.

  As a conventional example of the foldable floor heating mat, there is one described in Japanese Patent Laid-Open No. 2000-65365.

  The floor heating mat of the same publication has a substantially rectangular substrate (referred to as a mat plate in the publication) having a plurality of hot water piping grooves on the upper surface, and small joists. After arranging the hot water pipes in the grooves of each substrate alternately and covering the grooves, a heat radiation sheet made of aluminum foil or the like is continuously pasted on the upper surface of each substrate and small joists. .

  On the lower surface side of each substrate, a plurality of substantially V-shaped slits having a width narrower toward the upper surface side of the substrate are provided. These slits extend in a direction substantially parallel to the small joists. The depth of these slits is smaller than the thickness of each substrate. Between the upper end of each slit and the upper surface of the substrate, the portions on both sides of the substrate sandwiching the slit are connected. A coupling portion is formed.

It is preferable to provide the part 12.

  In addition, arrangement | positioning of the coupling | bond part 12 is not limited to this.

(4) Substrate F The configuration of the folded portion of the substrate F will be described with reference to FIG.

In the substrate F, a folding part 9 for folding the substrate F in a mountain or a valley is provided near the middle in the long side direction.

Since the portions 11 and 15 or the front side portion 16 and the back side portion 17 are coupled by the coupling portion 12, each of the substrates B, D, E, and F is handled as a single substrate until the substrates B, D, E, and F are folded. be able to.

  Further, since the coupling portions 12 are formed by providing the cut-shaped portions 12a, 12b on the upper and lower surfaces of the substrates B, D, E, F, the substrates B, D are formed as shown in FIG. 8 (a). , E, F can be folded easily, and when the substrates B, D, E, F are folded as shown in FIG. 8 (b), the substrates B, D, E, F can be easily folded. Each coupling part 12 can be divided.

  In manufacturing the floor heating mat 1, the substrates B, D, E, and F are not folded until the floor heating mat 1 is completed.

In this case, as described above, or a folded portion T ₃ as well as valley fold the folding portion T ₂ to crease, then fold mountain folding portion T _1, or folded portion while mountain fold the該折Ri portion T ₂ the T ₃ and valley fold and then valley-folded folding portion _{T 1.}

  At this time, since each of the boards B, D, E, and F is provided with the cut portions 12a and 12b on both plate surfaces, the coupling portion 12 is formed. It can be easily folded in both the folding and mountain folding directions. Further, when each of the substrates B, D, E, and F is turned back, each coupling portion 12 is divided, and adjacent portions are separated from each other with the folding portion 9 interposed therebetween, so that the thickness of each substrate A to H is reduced. Regardless, the floor heating mat 1 can be folded in either the mountain fold or valley fold direction.

However, the shape of the through slit is not limited to this.

  FIGS. 13 (a) and 13 (b) are sectional views of the same portion as FIG. 7 (b), showing examples of other shapes of the through slits.

  The through slit 13 ′ in FIG. 13A has a shape that becomes narrower toward the middle side of the substrate E in the thickness direction.

  Further, the through slit 13 ″ in FIG. 13B has a shape that becomes narrower toward the upper surface side of the substrate E.

  In contrast to FIG. 13B, the through slit 13 ″ may be formed so that the width becomes narrower toward the lower surface side of the substrate E.

  The shape of the above-described through slits 13, 13 ', 13' 'is merely an example, and the through slit can be formed in various shapes other than those illustrated.

iii) In the above-described embodiment, the coupling portion 12 is provided only in a part in the longitudinal direction of the folding portion 9 of each substrate B, D, E, F, and the remaining portion in the longitudinal direction of the folding portion 9 is a through slit. However, in the present invention, the coupling portion 12 may be provided over the entire length of the folding portion 9.

[Other configurations of floor heating mat]
i) The floor heating mat 1 does not have a small joist for nailing a flooring material or the like laid on the floor heating mat 1. For example, the floor heating mat 1 is disposed between adjacent substrates A, A ′, B, respectively. Small joists may be provided.
ii) In the above embodiment, the floor heating mat 1 is configured by combining a total of eight types of substrates A to H one by one, but the type and number of substrates are not limited to this. For example, the floor heating mat 1 may be configured by only one substrate.

[Materials]
Although the following is mentioned as an example of the material of each member of said floor heating mat 1, It is not limited to these.

  As a substrate of the floor heating mat, for example, a board made of foamed synthetic resin such as foamed polypropylene, foamed polystyrene, foamed polyethylene, foamed polyurethane or the like can be used. The foamed synthetic resin is preferably one in which the internal bubbles are closed cells from the viewpoint of heat insulation. Instead of this resin board, the substrate can be made of wood or the like.

  In the case of providing the small joist, the small joist is preferably wood, synthetic wood, synthetic resin or synthetic resin foam capable of nailing. Although illustration is abbreviate | omitted, the structure which affixed the reinforcement board on the upper and lower both surfaces of the small joist main body may be sufficient.

  As the soaking sheet and soaking plate, a metal foil such as aluminum or copper is preferable.

  By laminating a film of polyethylene terephthalate or the like on the surface of the soaking sheet, it is possible to prevent the soaking sheet from being damaged when the floor heating mat is packed or transported. The material of this film may be other than polyethylene terephthalate.

  Examples of the hot water pipe include a synthetic resin tube such as flexible polyethylene and a copper pipe.

  In addition, all of said embodiment shows an example of this invention and this invention is not limited to the structure of illustration.

  For example, in each of the above-described embodiments, four grooves 3 are formed on each of the substrates A, A ′, and B, but the number of grooves 3 is not limited to this.

  The number of substrates constituting the temperature control mat of the present invention is not limited to the number of the above embodiments. Further, the shape of each substrate is not limited to the shape of the above embodiment.

  Although the above embodiment relates to a floor heating mat, the temperature adjustment mat of the present invention may be arranged on a wall, a ceiling, or the like. Moreover, you may distribute | circulate heat media, such as oil other than water and antifreeze. A refrigerant may be circulated and used for cooling.
