  A present Example is the installation body 2 for the floor heating laid by the upper part of the heat source 1 provided in the floor structure part of a house (Japanese-style room). The heat source 1 has a well-known structure that allows warm water to pass through a circulation pipe disposed in a floor structure of a house.

  Specifically, the laying body 2 is composed of a tatami body 4 and a spacer 5 disposed in a laminated state below the tatami body 4.

  The tatami body 4 has a tatami mat 10 provided on the surface of a tatami core 9 (tatami floor) sewn with a heat conductive wire 3 as shown in FIG. In this specification, the term “suture” refers to a state in which the wire is meandered with respect to the object to be sutured (sewn so that a part of the wire is alternately exposed on the front and back surfaces of the object to be sutured). State).

  As shown in FIG. 2, the tatami core material 9 has a thin veneer plywood 12 and a nonwoven fabric 13 arranged on the upper side of two wood fiber boards 11 made of wood chips, and a lining sheet 14 on the lower side. Each member is integrally stitched with a wire 3 having good heat conductivity.

  As the wire 3, 56 copper or aluminum ultrafine wires having a diameter of about 180 μm are converged and twisted.

  When each member is sewn using the wire 3, the seam is sewn so that the seam is formed linearly on the front and back surfaces of the tatami core 9 as shown in FIG. 2.

  Further, on the surface of the tatami core material 9, a planar body 15 (aluminum foil) having the same shape as the tatami core material 9 is disposed in a polymerized state, and a non-woven fabric 16 is disposed thereon. Each member is integrated by sewing with a chemical thread (chemipet) (not shown).

  The reason why the planar body 15 is provided on the surface of the tatami core material 9 is to transmit heat from the wire 3 to the entire surface of the tatami body 4.

  Further, the nonwoven fabric 13 described above is provided for improving cushioning properties, and the nonwoven fabric 16 is provided for protecting the planar body 15 (aluminum foil).

  The planar body 15 may not be a single sheet covering the entire surface of the tatami core material 9, but may be a belt shape along the seam of the wire 3 of the tatami core material 9. In this case, the cost and light weight can be reduced by reducing the material. It will be excellent in chemistry.

  As the tatami mat table 10, a commonly used one is used.

  From the above, the tatami body 4 is provided with a heat transfer function by the wire 3 between the front surface portion 4a and the back surface portion 4b.

  As shown in FIG. 2, the spacer 5 is provided with a surface material 18 on the surface of a core material 17 sewn with a wire 6 having good heat conductivity.

  As shown in FIG. 2, the core material 17 has a lining sheet 20 disposed under the three wood fiber boards 19 made of wood chips, and these members are integrally stitched together with a wire material 6 having good heat conductivity. It is configured. The wire 6 has the same configuration as the wire 3 described above.

  When each member is sewn using the wire 6, the seam is sewn on the front surface and the back surface of the core material 17 so as to form a straight line as shown in FIG. 2.

  The surface material 18 provided on the surface of the core material 17 is arranged in a polymerized state on the core material 17, and is disposed from above the planar material 8 (aluminum foil) having the same shape as the core material 17. And is integrated by stitching a core material 17 protected by the woven fabric 21 with a chemical thread (not shown).

  As shown in FIGS. 3 and 4, the planar body 8 is disposed between the wire 6 of the spacer 5 and the wire 3 of the tatami body 4 disposed above the spacer 5. As shown in the figure, when the tatami body 4 and the spacer 5 are laminated, the wire 3 of the tatami body 4, the planar body 8, and the wire 6 of the spacer 5 are configured to be in a juxtaposed state.

  Therefore, the heat from the wire 6 can be reliably transmitted to the wire 3 through the planar body 8.

  The planar body 8 may not be a single sheet covering the entire surface of the core material 17 but may be a belt shape along the seam of the wire material 6 of the core material 17. In this case, the cost can be reduced and the weight can be reduced by reducing the material. It will excel.

  From the above, the spacer 5 is provided with a heat transfer function by the wire 6 between the front surface portion 5a and the back surface portion 5b.

  Next, the present applicant confirmed the thermal resistance of the laying body 2 having the above-described configuration (the smaller the thermal resistance, the smaller the heat loss, but the laying body 2 according to the present example includes the tatami body 4, the spacer 5, and the like. It is considered that the thermal resistance is larger than that of the conventional example due to the structure composed of a plurality of members.

  That is, as shown in FIG. 6, as a condition for obtaining the thermal resistance, the thickness of the entire laying body 2 is 60 mm (the tatami mat 10 is 5 mm, the tatami core 9 is 25 mm, and the spacer 5 is 30 mm). .

  Further, the number of wires 3 and 6 for sewing the tatami core material 9 and the spacer 5 having different thicknesses is 16 for the tatami core material 9 and 32 for the spacer 5. It is a book.

In addition, heat resistance (0.035 m ² h ° C./kcal) in the upper air layer generated between the tatami mat 10 and the tatami core material 9 and in the lower air layer generated between the tatami core material 9 and the spacer 5 is also taken into consideration. Yes.

The thermal resistance of the erected body 2 is obtained from the above-described conditions. That is, as shown in FIG. 6, the thermal resistance of the tatami table 10 (0.051 m ² h ° C./kcal) and the thermal resistance of the upper air layer (0. 035 m ² h ° C./kcal), the thermal resistance of the tatami core 9 (0.071 m ² h ° C./kcal), the thermal resistance of the lower air layer (0.035 m ² h ° C./kcal), and the heat of the spacer 5 The sum of the resistance (0.044 m ² h ° C./kcal) is 0.236 m ² h ° C./kcal.

As a floor heating tatami mat, a thermal resistance of 0.25 m ² h ° C./kcal or less is a numerical value that becomes a reference when actually commercialized, and as described above, the thermal resistance of the erected body 2 according to the present embodiment. Was 0.236 m ² h ° C./kcal, so that it was confirmed that the product could be used sufficiently.

  Since the present embodiment is configured as described above, when the laying body 2 is laid on the upper side of the heat source 1, the spacer 5 is laid on the upper side of the heat source 1, and the tatami body 4 is laid on the upper side of the spacer 5. At this time, the wire 3 of the tatami body 4, the planar member 8, and the wire 6 of the spacer 5 are arranged side by side vertically. Note that the tatami body 4 and the spacer 5 may be laid on the upper side of the heat source 1 in a stacked state.

  Heat generated from the heat source 1 is transferred to the tatami body 4 stacked on the upper side of the spacer 5 via the spacer 5 (particularly, the wire 6 and the planar body 8) laid on the upper side of the heat source 1, and this spacer. Heat from 5 is transferred from the back surface portion 4b to the front surface portion 4a by the wire 3 and the planar body 15, and the surface of the tatami body 4 becomes warm.

  Therefore, according to the present embodiment, the tatami body 4 may have a thin structure as compared with the case where the above-described conventional example is applied to a thick tatami mat. Therefore, for example, when the wire 3 is sutured, the suture needle is not easily broken and the wire 3 Will not be damaged, and will be excellent in mass productivity. Moreover, as the laying body 2 is divided into a tatami body 4 and a spacer 5, the weight per piece does not increase, so transport work and carry-in work can be performed. It will be easy.

  Further, in this embodiment, a planar body 8 having heat conductivity is disposed between the wire 6 of the spacer 5 and the wire 3 of the tatami body 4 disposed above the spacer 5. Is a full body, and when the tatami body 4 and the spacer 5 are laminated, the wire 3 of the tatami body 4, the planar body 8, and the wire 6 of the spacer 5 are configured to be in a juxtaposed state. Therefore, even in the heat transfer structure using the wire rods 3 and 6, heat transfer is surely performed, which is excellent in terms of cost and weight reduction.

  Moreover, since the present Example employs the wire 6 as the heat transfer structure of the spacer 5 like the tatami body 4, the entire spacer 5 can be provided with a heat transfer function, and further, as the heat transfer structure Since minimal material is required, the cost and weight are excellent.
