  Patent Document 2 describes a temperature control floor in which a cork board is installed on a temperature control mat and a carpet is laid on the cork board.

JP 11-151153 A Reality 6-40766

  When a carpet is laid on a temperature-controlled floor as in Patent Document 1, heat is trapped between the floor surface material of the temperature-controlled floor and the carpet during floor heating, causing warping and cracking in the floor surface material. May be easier. In addition, liquids such as drinks and pet urine spilled on the floor may penetrate the seams between the floor surface materials and the floor surface material itself to permeate the temperature control mat, thereby reducing the durability of the temperature control mat.

  In Patent Document 2, an intermediate material made of cork having relatively low liquid permeability is installed between the temperature control mat and the carpet. The carpet is laid on the intermediate material made of such a wood-based material. In such a case, the adsorbing means such as an adhesive resin and a suction cup for adsorbing and holding the carpet is difficult to adsorb sufficiently to the intermediate material, and it may be difficult to hold the carpet firmly on the floor surface.

  In addition, when a carpet is laid on an intermediate material made of a wood-based material, there is a possibility that heat from the temperature control mat is not easily transmitted to the carpet.

  The present invention can more reliably prevent liquids such as drinks spilled on the floor and pet urine from penetrating from the floor surface material to the temperature control mat, and the floor surface material can be more reliably placed on the floor surface. An object of the present invention is to provide a temperature-controlled floor that can be held and can more uniformly adjust the temperature of the floor surface.

  In the temperature control floor of the present invention (Claim 1), a temperature control mat is installed on the floor foundation of a building room, an intermediate material is installed on the temperature control mat, and the floor surface is formed on the intermediate material. In the temperature control floor formed by laying the material, a liquid-impermeable layer for preventing the penetration of liquid from the indoor side is provided so as to cover the upper surface of the intermediate material. It is characterized by comprising a woody material.

  The temperature-controlled floor according to claim 2 is characterized in that, in claim 1, the liquid-impermeable layer is made of metal.

  The temperature-controlled floor according to claim 3 is characterized in that, in claim 2, the metal is aluminum or an aluminum alloy.

  The temperature-controlled floor according to claim 4 is characterized in that, in any one of claims 1 to 3, the intermediate material is made of a wood-based material.

  The temperature control floor according to claim 5 is the temperature control floor according to any one of claims 1 to 4, wherein the temperature control mat has a driveable portion capable of driving a nail or a screw from an indoor side, and the intermediate material is The nail or the screw is fixed to the temperature control mat by being driven from above the liquid-impervious layer through the liquid-impervious layer and the intermediate material into the driveable part. It is.

  A temperature control floor according to a sixth aspect is the temperature control floor according to any one of the first to fifth aspects, wherein a plurality of the intermediate materials are arranged along the upper surface of the temperature control mat so as to cover the upper surface of each intermediate material. The liquid-impervious layers are provided respectively, and the adjacent liquid-impermeable layers are lined with a weathering material made of a liquid-impermeable material.

  The temperature-controlled floor according to claim 7 is characterized in that, in claim 6, the weathering material is made of a metal foil, and the weathering material is bonded across the upper surface of the adjacent liquid-impermeable layer. Is.

  The temperature-controlled floor according to claim 8 is characterized in that, in any one of claims 1 to 7, the floor surface material is a carpet.

  In the temperature control floor of the present invention, since an impermeable layer for preventing the penetration of liquid from the indoor side is provided so as to cover the upper surface of the intermediate material, for example, drinks spilled on the floor or Since the liquid such as pet urine can be more reliably prevented from penetrating through the intermediate material and penetrating to the temperature control mat, the durability of the temperature control mat becomes high.

  In the present invention, the liquid-impermeable layer is made of a non-woody material. Thereby, compared with the case where a floor surface material is laid directly on an intermediate material made of a wood-based material as in Patent Document 2, for example, the floor surface material can be more firmly adsorbed to the liquid-impermeable layer. As a result, the floor surface material can be more reliably held on the floor surface.

  In general, non-woody materials tend to have higher thermal conductivity than wood-based materials, so even if there is unevenness in the way heat is transmitted from the temperature control mat in the intermediate material, liquid impermeability Since heat is easily transferred to the entire layer, this unevenness is eliminated, and the temperature of the floor surface can be adjusted more uniformly.

  In the present invention, the wood-based material refers to solid wood, laminated wood, laminated material, and a broad sense of wood, such as a molding material of plant fibers containing wood, or a non-woody material. Refers to other materials. Examples of the non-woody material include metals, synthetic resins (including those derived from woody materials), glass, natural stone materials, artificial stone materials, and the like.

  This liquid-impervious layer is preferably a metal from the standpoint of strength and rigidity, liquid impermeability, and thermal conductivity, as in claim 2, and is particularly preferably aluminum or aluminum from the standpoint of simplicity and thermal conductivity, as in claim 3. Alloys are preferred.

  As a fourth aspect of the present invention, a wood-based material is preferable as a constituent material for the intermediate material because of its simplicity.

  As described in claim 5, when the temperature control mat is provided with a driveable portion where nails or screws can be driven from the indoor side, and the impermeable layer and the intermediate material are fixed to the temperature control mat with nails or screws, By driving a nail or a screw into the driveable portion, it is possible to more reliably prevent damage to members such as piping and a heater for circulating the heat medium of the temperature control mat due to the driving of the nail or screw. The liquid-permeable layer and the intermediate material can be firmly fixed to the temperature control mat.

  By fixing the liquid-impermeable layer and the intermediate material to the temperature control mat with nails or screws, the intermediate material can be easily separated from the temperature control mat by removing the nails or screws. Therefore, for example, when maintenance of the temperature control floor is required, even if it is necessary to replace the intermediate material, the intermediate material can be separated from the temperature control mat by removing this nail or screw, and only the intermediate material can be replaced. Since the temperature control mat can be reused, the maintenance cost of the temperature control floor can be kept relatively low.

  As described in claim 6, by lining between adjacent liquid-impermeable layers with a weathering material made of a liquid-impermeable material, for example, liquids such as drinks spilled on the floor and pet urine pass through the intermediate material. Thus, it is possible to more reliably prevent the temperature control mat from penetrating.

  As described in claim 7, the weathering material is preferably made of a metal foil from the viewpoint of durability, ease of construction, thermal conductivity, and the like. By sticking the covering material made of this metal foil across the upper surfaces of the adjacent liquid-impermeable layers, the space between the liquid-impermeable layers can be more reliably lined.

  According to the present invention, as in claim 8, for example, even a carpet in which a liquid such as a drink spilled on the floor or pet urine is relatively easy to penetrate to the back side can be suitably used as a floor surface material.

A floor surface material 30 is laid on the material 20. In the present invention, a liquid-impermeable layer 21 is provided so as to cover the upper surface of the intermediate material 20. The liquid-impermeable layer 21 is made of a non-woody material.

  In this embodiment, the temperature-controlled floor is for performing floor heating. In this embodiment, the temperature control mat 10 heats the floor surface material 30 with the heat of warm water supplied from a boiler (not shown). In this embodiment, the floor surface material 30 is a carpet.

[Configuration of Temperature Control Mat 10]
The temperature control mat 10 has a plurality of substantially rectangular substrates 11 and a plurality of small joists 12 arranged alternately with their longitudinal directions as parallel directions, and a pipe arrangement formed on the upper surface of each substrate 11. The hot water pipe 14 is routed in the groove 13 (FIG. 5). A soaking plate 15 is disposed from the inner surface of the groove 13 to the upper surface of the substrate 11 so as to contact the hot water pipe 14. On the upper surface of the substrate 11, a soaking sheet 16 is attached so as to close the groove 13 that accommodates the hot water pipe 14. The soaking sheet 16 is continuously attached to the upper surface of each substrate 11 and each small joist 12.

  In this embodiment, each small joist 12 is a driveable portion (claim 5) capable of driving a nail or a screw from the indoor side. In general, the standard temperature control mat 10 has a length of each side of the outer periphery which is substantially an integral multiple of 303 mm (one scale). The interval between the intermediate portions in the width direction of the matching small joists 12, 12 (the direction orthogonal to the longitudinal direction of each small joist 12 and parallel to the upper surface of the temperature control mat 10) is substantially 303 mm.

  In this embodiment, a connecting space (not shown) for connecting adjacent substrates 11 and 11 is formed in the middle of each small joist 12 in the longitudinal direction, and the groove 13 passes through this connecting space. It is formed continuously from one adjacent substrate 11 to the other substrate 11. The hot water pipe 14 is also continuously routed from the groove 13 of one adjacent substrate 11 to the groove 13 of the other substrate 11 through the groove 13 formed in this connection space. In this embodiment, four grooves are provided on the upper surface of each substrate 11 except for the substrate 11 (11A) at the lower right in FIG. Six grooves 13 are extended in the lower right substrate 11A.

  That is, the temperature control mat 10 has a three-circuit hot water circulation pipe configuration in which three hot water pipes 14 are routed as a whole. Since the forward side and the return side of the hot water pipe 14 for three circuits are routed on the lower right substrate 11A in FIG. 4, a total of six (2 × 3 = 6) grooves 13 are provided, respectively. The warm water piping 14 on the forward side or the return side of each circuit is accommodated in each. Each of the other substrates 11 is provided with four grooves 13, and the outgoing side and the return side of the hot water pipe 14 for two circuits are routed.

  A notch 11a is provided in the corner of the lower right substrate 11A in FIG. 4, and a header 17 is disposed in the notch 11a. The end of each groove 13 of the substrate 11A faces the notch 11a, and both end sides of each hot water pipe 14 are drawn from the end of each groove 13 into the notch 11a and connected to the header 17. ing. The header 17 is connected to a forward main pipe (not shown) for supplying hot water from the boiler to the header 17 and a return main pipe (not shown) for returning hot water from the header 17 to the boiler. Yes. Hot water sent from the boiler to the header 17 via the outgoing main pipe is distributed to the outgoing side of each hot water pipe 14 within the header 17 and flows through the hot water pipe 14 and circulates on the temperature control mat 10. To do. Thereafter, the hot water returned to the header 17 from the return side of each hot water pipe 14 joins in the header 17 and is returned from the header 17 to the boiler via the return side main pipe.

  As shown in FIGS. 2, 3 and 5, in this embodiment, each substrate 11 has a thickness such that the groove 13 is exposed on the bottom surface. The depth of the groove 13 from the upper surface of each substrate 11 is substantially equal to the outer diameter of the hot water pipe 14. That is, the thickness of each substrate 11 is also approximately equal to the outer diameter of the hot water pipe 14.

  In general, as the hot water pipe 14, a standard product that is generally distributed is used. In this embodiment, as the hot water pipe 14, a standard hot water pipe having an outer diameter of 6 mm is used. Note that the hot water pipe having an outer diameter of 6 mm of this standard product has an outer diameter of substantially 6 mm and allows a dimensional error of about ± 0.2 to 0.4 mm. However, in the present invention, the outer diameter of the hot water pipe 14 is not limited to this, and a standard hot water pipe having an outer diameter other than this may be used. In the present invention, a hot water pipe 14 other than a standard product may be used. In the present invention, the outer diameter of the hot water pipe 14 is usually 4 to 10 mm, particularly preferably 5 to 7 mm.

The thickness H ₁ (FIG. 5) of each substrate 11 is usually preferably 12 mm or less, particularly 9 mm or less, particularly 6 mm. In particular, the thickness H ₁ of each substrate 11 is usually preferably the outer diameter of the hot water pipe 14 +0 to 10 mm, particularly the outer diameter of the hot water pipe 14 +0 to 5 mm. By thus reducing the thickness H ₁ of each substrate 11, the total thickness of the temperature control mat 10 can be reduced. Thereby, it becomes possible to reduce the level difference between the floor of the room where the temperature control floor is constructed and the floor of the other room or hallway.

  In this embodiment, a backing sheet 18 is provided so as to cover each groove 13 exposed on the lower surface of each substrate 11. The backing sheet 18 is disposed along the lower surface of each substrate 11 and is attached to each substrate 11 with an adhesive or the like. As shown in FIGS. 2, 3 and 5, in this embodiment, the backing sheet 18 is in the form of an elongated band and covers the grooves 13 one by one, but a plurality of adjacent grooves 13 may be continuously covered, or substantially the entire lower surface of each substrate 11 may be covered.

  In consideration of the case where the temperature control floor is constructed on the existing floor surface, the bottom surface of the temperature control mat is used to prevent the wax adhering to the existing floor surface from entering the temperature control mat. A nonwoven fabric may be attached so that the whole may be covered. In that case, for example, the backing sheet 18 may be provided only in a portion of the groove 13 where the soaking plate 15 is not distributed. Alternatively, all the backing sheet 18 may be omitted.

  In the present invention, each substrate 11 may be thick so that the groove 13 is not exposed on the lower surface thereof.

In this embodiment, the thickness of the small joists 12 between the substrates 11 to each other, the thickness H ₁ -0 of each substrate 11 substantially equal to or what is smaller thickness to a predetermined thickness than (e.g. substrate 11 .About 1 to 0.5 mm).

  In this embodiment, as shown in FIGS. 2, 3 and 5, the heat equalizing plate 15 is formed from the U-shaped portion 15a along the inner surface of the groove 13 and from both ends (upper ends) of the U-shaped portion 15a. And a pair of flange portions 15b extending laterally along the upper surface of the substantially Ω-shaped cross section. The U-shaped portion 15a of the heat equalizing plate 15 is disposed in the groove 13, and the hot water pipe 14 is accommodated in the groove 13 so as to be fitted into the U-shaped portion 15a.

  The soaking sheet 16 is affixed to the substrate 11 from above the flange portion 15 b of the soaking plate 15.

In this embodiment, the area of the temperature control mat 10 is smaller than the entire area of the floor of the room where the temperature control floor is constructed. Therefore, as shown in FIG. 4, after the temperature control mat 10 is installed on the temperature control mat installation area of the floor base F, a dummy is formed so as to fill the space between the outer periphery of the temperature control mat 10 and the outer periphery of the room floor. The material 40 is distributed. In this embodiment, the thickness of the dummy material 40 is the total thickness of the temperature control mat 10 (≈the thickness of the substrate 11 + the thickness of the soaking sheet 16 + the thickness of the backing sheet 18) H ₂ ( (Fig. 3) is almost equal (preferably equivalent to the thickness of small joist 12). In this embodiment, the intermediate member 20 is constructed so as to cover both the upper surface of the temperature control mat 10 and the upper surface of the dummy member 40.

<Material of temperature control mat 10 and material of dummy material 40>
Although the following are mentioned as an example of the material of each member of the temperature control mat 10, It is not limited to these.

  As a constituent material of the substrate 11, for example, wood can be used in addition to foamed synthetic resins such as foamed polypropylene, foamed polystyrene, foamed polyethylene, and foamed polyurethane. The foamed synthetic resin is preferably one in which the internal bubbles are closed cells from the viewpoint of heat insulation.

  As a constituent material of the small joist 12, wood, synthetic wood or synthetic resin or synthetic resin foam capable of nailing or screwing is preferable. Although illustration is omitted, a configuration in which reinforcing plates are attached to the upper and lower surfaces of the main body of the small joists 12 may be used.

  The soaking sheet 16 and the soaking plate 15 are preferably aluminum, an aluminum alloy, or a metal foil such as copper.

  A film such as polyethylene terephthalate may be laminated on the surface of the soaking sheet 16. By doing so, it is possible to prevent the soaking sheet 16 from being damaged when the temperature control mat 10 is packed or transported. The material of this film may be other than polyethylene terephthalate.

  Examples of the hot water pipe 14 include a synthetic resin tube such as flexible polyethylene and a copper pipe.

  The backing sheet 18 is preferably made of a low heat conductive material. As this low thermal conductive material, a nonwoven fabric, a synthetic resin sheet, paper, or the like can be used.

  The dummy material 40 is usually manufactured by cutting or adding a standard plywood that is generally distributed. The dummy material 40 may be made of a material other than the standard plywood.

[Configuration of Intermediate Material 20 and Impervious Layer 21]
The intermediate member 20 is a substantially square plate-like member extending along the upper surface of the temperature control mat 10. In this embodiment, as shown in FIG. 1, the length of at least one side of the outer periphery of the intermediate material 20 is smaller than the length of at least one side of the floor of the chamber. Is distributed along the upper surface of the temperature control mat 10 and the upper surface of the dummy material 40, so that the entire upper surface of the temperature control mat 10 and the upper surface of the dummy material 40 are covered with these intermediate materials 20. The adjacent intermediate members 20, 20 are arranged so that one side of each of the intermediate members 20 abuts each other. Hereinafter, the intermediate material 20 covering the entire upper surface of the temperature control mat 10 and the upper surface of the dummy material 40 may be collectively referred to as an intermediate material 20 group.

  Each intermediate member 20 is arranged so that at least one side overlaps one of the small joists 12 of the temperature control mat 10.

  The intermediate material 20 is manufactured by cutting a plate material such as a standard plywood, which is generally distributed, so that the length of each side is substantially an integral multiple of 303 mm. At that time, the length and arrangement of each side of each intermediate material 20 are arranged such that at least one side of each intermediate material 20 arranged on the temperature control mat 10 overlaps any small joist 12 of the temperature control mat 10. A pattern or the like is set. In addition, there is no restriction | limiting in particular in the number and arrangement pattern of the intermediate material 20 required to cover the whole upper surface of the temperature control mat 10. FIG. The intermediate material 20 may be sized to cover the entire top surface of the temperature control mat 10 with a single sheet.

  As the constituent material of the intermediate material 20, a wood-based material is simple and suitable. As the wood material constituting the intermediate material 20, even when the intermediate material 20 is fixed to the temperature control mat 10 by a local fixing means such as a nail or a screw, the entire intermediate material 20 is firmly fixed. It is preferable that it has strength and rigidity that can be fixed to 10. More specifically, the wood-based material constituting the intermediate material 20 is preferably plywood, particle board, fiber board, or the like. In particular, plywood is preferable from the viewpoint of its strength and rigidity and ease of construction. The liquid-impermeable layer 21 and the intermediate member 20 may be fixed by a fixing means other than a nail or a screw.

  As shown in FIGS. 1 to 3, the liquid-impermeable layer 21 is provided so as to cover substantially the entire upper surface of the group of intermediate members 20 arranged on the temperature control mat 10. That is, the temperature control mat 10 has the entire upper surface covered with the liquid-impermeable layer 21 from above the intermediate material 20 group. The liquid-impermeable layer 21 is preferably bonded to the upper surface of the intermediate material 20, but may not be bonded. When the liquid-impervious layer 21 is bonded to the upper surface of the intermediate member 20, an adhesive or a pressure-sensitive adhesive is simple and suitable as the bonding means. The coupling means is not limited to this.

  In this embodiment, the intermediate member 20 and the liquid-impermeable layer 21 are manufactured as a composite plate in which the liquid-impermeable layer 21 is bonded and integrated with the upper surface of the intermediate member 20 in advance as shown in FIG. is there. The liquid-impermeable layer 21 covers the entire upper surface of the intermediate material 20 at the stage of manufacturing as this composite plate. Therefore, by cutting this composite plate so that the intermediate material 20 has the above-mentioned predetermined shape, the liquid-impermeable layer 21 is also integrally cut with the intermediate material 20 in the same shape. Then, by arranging the composite plate group cut into a predetermined shape on the temperature control mat 10 and the dummy material 40 with the above-described predetermined arrangement pattern so that the liquid-impermeable layer 21 is on the upper side, The entire upper surface of the temperature control mat 10 and the upper surface of the dummy material 40 are covered with the intermediate material 20 group, and the entire upper surface of the intermediate material 20 group is covered with the liquid-impermeable layer 21.

  The liquid-impermeable layer 21 may be formed in a plate shape separately from the intermediate material 20 and distributed on the intermediate material 20 at the construction site. In this case, a plurality of liquid-impermeable layers 21 may cover the entire upper surface of the intermediate material 20 group, or a single liquid-impermeable layer 21 may cover the entire upper surface of the intermediate material 20 group. Also good.

  The non-woody material constituting the liquid-impermeable layer 21 is preferably a metal from the viewpoint of strength and rigidity, liquid-imperviousness, thermal conductivity, adsorbability of the adsorbing means of the floor surface material 30, and the like. Aluminum or aluminum alloy is preferable from the viewpoint of thermal conductivity. However, the constituent material of the liquid-impermeable layer 21 may be a metal other than aluminum or an aluminum alloy, or may be a material other than a metal. For example, the constituent material of the liquid-impermeable layer 21 may be a synthetic resin or the like as long as the liquid-impervious property, the thermal conductivity, and the adsorptivity of the adsorbing means of the floor surface material 30 are sufficiently ensured. In addition, the constituent material of the liquid-impermeable layer 21 has liquid-impervability that can sufficiently prevent the liquid from penetrating from the indoor side to the temperature control mat 10, and has sufficient thermal conductivity. And as long as the adsorption | suction means of the floor surface material 30 has the adsorptivity which can fully adsorb | suck, it will not be limited to a metal or a synthetic resin.

  When the liquid-impermeable layer 21 is made of metal, the surface of the liquid-impermeable layer 21 is made of a synthetic resin in order to strengthen the adhesion with the intermediate material 20 and to prevent corrosion and breakage of the metal. A coating layer may be provided.

The thickness H ₃ (FIG. 3) of the intermediate member 20 is usually preferably 2 to 12 mm, particularly 3 to 9 mm, particularly 5 to 6 mm, and the thickness H _{4 of the} liquid-impermeable layer 21 (FIG. 3). ) Is usually from 0.01 to 0.1 mm, particularly preferably from 0.03 to 0.08 mm, particularly preferably from 0.04 to 0.06 mm. The total thickness (H ₃ + H ₄ ) of the intermediate material 20 and the liquid-impermeable layer 21 is usually 12 mm or less, particularly 9 mm or less, and particularly preferably 6 mm or less.

Thus, by reducing the total thickness (H ₃ + H ₄ ) of the intermediate material 20 and the liquid-impermeable layer 21, the intermediate material 20 and the liquid-impermeable liquid are formed on the temperature control mat 10 and the dummy material 40. The entire thickness of the temperature control floor formed by distributing the layer 21 can also be reduced. Thereby, it becomes possible to reduce the level difference between the floor of the room where the temperature control floor is constructed and the floor of the other room or hallway. Moreover, the heat from the temperature control mat 10 can be efficiently transmitted into the room.

  In this embodiment, the liquid-impermeable layer 21 (in this embodiment, a composite plate of the intermediate material 20 and the liquid-impermeable layer 21) is distributed so as to cover the temperature control mat 10 and the dummy material 40. As shown in FIGS. 1 to 3, the adjacent liquid-impervious layers 21 and 21 are lined with a weathering material 22 made of a liquid-impermeable material.

  The weathering material 22 is preferably made of a metal foil in terms of durability, ease of construction, thermal conductivity, and the like. As this metal foil, for example, aluminum or aluminum alloy foil, copper or copper alloy foil, or the like is particularly preferable from the viewpoint of thermal conductivity, and aluminum or aluminum alloy foil is particularly preferable. The weathering material 22 is not limited to a metal foil. For example, a synthetic resin tape or the like may be used as the weathering material 22.

  The weathering material 22 is disposed so as to overlap the upper surfaces of both liquid-impervious layers 21 and 21 across the joint between the adjacent liquid-impervious layers 21 and 21, and both liquid-impervious layers are formed by an adhesive, an adhesive, or the like. It is affixed on the upper surface of 21 and 21. By doing in this way, between the liquid-impermeable layers 21 and 21 can be more reliably marked by the weathering material 22.

[Floor surface material 30]
In this embodiment, a so-called tile carpet is used as the floor surface material 30. The tile carpet has a substantially rectangular plate shape in which the length of each side of the outer periphery is a standard dimension (substantially an integral multiple of 303 mm) smaller than the length of each side of the floor of the room. As shown in the figure, the entire floor surface is covered by regularly arranging a plurality of sheets on the floor.

  By using such a tile carpet as the floor surface material 30, for example, when a part of the tile carpet is soiled or damaged, it is only necessary to replace the tile carpet of that part, so that maintenance is easy. And economical. Further, for example, even when a liquid such as a drink spilled on the floor or pet urine penetrates to the back side of the tile carpet and the liquid-impervious layer 21 becomes dirty, only the tile carpet in that portion is peeled off to form the liquid-impermeable layer 21. Since it can be accessed, the liquid-impermeable layer 21 can be efficiently cleaned.

  The floor surface material 30 may be other than carpets (including tile carpets), and may be, for example, a flooring material made of a wood-based material.

  In this embodiment, an adsorbing means (not shown) is provided on the lower surface of the floor surface material 30, and the floor surface material 30 is not formed by pressing the floor surface material 30 on the liquid-impermeable layer 21. The liquid-permeable layer 21 is configured to be adsorbed on the upper surface. This adsorbing means is preferably one that is detachably adsorbed to the liquid-impermeable layer 21. Examples of such adsorption means include polyolefin resin and rubber added with a tackifying resin, and a suction cup. By using such an adsorbing means, the floor surface material 30 can be easily removed or reattached during maintenance or the like.

  Note that the means for attaching the floor surface material 30 to the liquid-impermeable layer 21 is not limited to this. The floor surface material 30 may be attached to the upper surface of the liquid-impermeable layer 21 or the dummy material 40 with an adhesive, an adhesive material, or the like.

[How to install a temperature-controlled floor]
First, as shown in FIG. 1, the temperature control mat 10 is installed on the temperature control mat installation area of the floor base F of the room. In addition, the header 17 is disposed in the notch 11a of the substrate 11A, and the forward and return main pipes connected to the boiler, and both ends of each hot water pipe 14 drawn out to the notch 11a are headers. 17 is connected. Next, a dummy material 40 is laid around the temperature control mat 10 so as to cover the remaining portion of the floor base F. In addition, the construction time of the dummy material 40 is not limited to this. For example, the dummy material 40 is laid first on the floor base F, leaving the temperature control mat installation area, and the temperature control mat 10 is installed later. You may do it.

  Next, the composite plate group of the intermediate material 20 and the liquid-impermeable layer 21 that has been cut into a predetermined shape in advance is arranged on the temperature control mat 10 and the dummy material 40 in a predetermined arrangement pattern. At that time, at least one side of each intermediate material 20 (and the liquid-impermeable layer 21) is overlapped with the small joists 12 of the temperature control mat 10, and nails or screws (not shown) are placed on the liquid-impermeable layer 21. Then, the liquid impervious layer 21 and the intermediate material 20 are penetrated and driven into the small joist 12 to fix each intermediate material 20 and the liquid impervious layer 21 to the small joist 12. When the intermediate material 20 overlaps the dummy material 40, nails or screws may be driven into the dummy material 40 to fix the liquid-impermeable layer 21 and the intermediate material 20 to the dummy material 40. Thereafter, the weathering material 22 is pasted over the upper surfaces of these liquid-impermeable layers 21 and 21 so as to be spread between the adjacent liquid-impermeable layers 21 and 21.

  Thereafter, a floor surface material 30 is laid so as to cover the entire floor surface continuously on the upper surface of each impermeable layer 21, and the floor surface material 30 is adsorbed to the upper surface of each impermeable layer 21. Thereby, the construction of the heating floor is completed.

  In the heating floor constructed in this way, since the liquid-impermeable layer 21 for preventing the permeation of liquid from the indoor side is provided so as to cover the upper surface of the intermediate member 20, for example, the floor Since it is possible to more reliably prevent liquids such as spilled drinks and pet urine from passing through the intermediate material 20 and penetrating to the temperature control mat 10, the temperature control mat 10 has high durability.

  The liquid-impermeable layer 21 is made of a non-woody material. Thereby, for example, the floor surface material 30 can be more firmly adsorbed to the liquid-impermeable layer 21 than when the floor surface material 30 is laid directly on the intermediate material 20 made of a wood-based material. For this reason, the floor surface material 30 is more reliably held on the floor surface.

  Further, since the liquid-impermeable layer 21 is made of a non-woody material having a higher thermal conductivity than the wood-based material, even if the intermediate material 20 has unevenness in how heat is transmitted from the temperature control mat 10. In the liquid-impermeable layer 21, heat is easily transmitted to the whole, so that this unevenness is eliminated and the temperature of the floor surface can be adjusted more uniformly.

  In this embodiment, the space between the adjacent liquid-impermeable layers 21 and 21 is covered with the weathering material 22 made of a liquid-impermeable material, so that liquids such as drinks and pet urine spilled on the floor can be obtained. It is possible to prevent the penetration through the intermediate material 20 to the temperature control mat more reliably.

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

In the above embodiment, the temperature control mat is configured such that the hot water pipe is routed on the substrate and the hot water pipe is circulated and heated, but the configuration of the temperature control mat is not limited to this. . For example, the temperature control mat may be provided with an electric heater and heated by the heat of the electric heater.

  Although the above embodiment shows an example in which warm water is circulated through the piping of the temperature control mat and heated, for example, a coolant such as cold water may be circulated through the piping for cooling. Moreover, you may distribute | circulate heat media, such as oil other than water and antifreeze.
