Incidentally, if the thickness t ₁ of the adhesive material 20 is excessively small, or subfloor F is not a rough surface, if there is Furiku the underfloor F, can not cope with this, the adhesive material There is a possibility that 20 may not exhibit sufficient adhesive strength. When the thickness t ₁ of the adhesive material 20 is excessively large, stepping comfort of heating floors constructed using the floor heating mat 1 may be deteriorated.

The distance d ₃ (FIG. 2) between the outer peripheral edges of the substrates 11 to 16 and the adhesive material 20 is preferably 10 to 60 mm, particularly 40 to 50 mm. Thus, by providing the adhesive material 20 at a position separated from the outer peripheral edge of each of the substrates 11 to 16, it is possible to apply the adhesive 30 in the vicinity of the end portion of each of the substrates 11 to 16 that is relatively likely to be warped. In addition, since the adhesive 30 can be applied at an appropriate interval from the end portions of the substrates 11 to 16, it is possible to suppress the adhesive 30 from protruding from the end portions of the substrates 11 to 16. .

Covered. In general, the covering material 21 is attached in advance to one surface of the double-sided adhesive tape in the production process of the double-sided adhesive tape, and the adhesive 20 made of this double-sided adhesive tape is used when the floor heating mat 1 is manufactured. Is attached to the lower surface of each of the substrates 11 to 16 in a state where one surface is covered with the covering material 21 from the beginning.

  In this embodiment, as shown in FIGS. 2 and 5, in order to prevent the covering material 21 from being inadvertently peeled off from the adhesive material 20 when the floor heating mat 1 is transported, the bottom surface of the covering material 21 is used. And the peeling prevention material 22 is adhered ranging over the lower surfaces of the board | substrates 11-16 of the circumference | surroundings. This peeling prevention material 22 is difficult to peel off from the lower surface of the substrates 11 to 16 due to vibration or light rubbing process during transportation of the floor heating mat 1, but can be peeled relatively easily when an operator tries to peel off. It has become. As such an anti-peeling material 22, for example, a general single-sided adhesive tape for temporary fixing, which is formed by adhering or impregnating an adhesive material having a relatively weak adhesive force on one side of a belt-like or sheet-like base material ( Or a sheet | seat) etc. are simple and preferable. In addition, the peeling prevention material 22 is not limited to this.

  As shown in FIGS. 2 and 5, even if the anti-peeling material 22 is provided on both ends in the extending direction of the covering material 21, it is usually sufficient to prevent the covering material 21 from peeling from the adhesive material 20. However, the anti-peeling material 22 may be provided also in the middle of the extending direction of the covering material 21.

When the mark 31 is provided in the vicinity of the short side of the substrate 12, the end of the adhesive material 20 provided along the short side on the substrate 11 side, and the long side of the substrate 12 on the substrate 11 side It is preferable to provide the mark 31 between and / or between the end of the adhesive material 20 on the substrate 13 side and the long side of the substrate 12 on the substrate 13 side. When the mark 31 is provided in the vicinity of the short side of the substrate 13, the end on the substrate 12 side of the adhesive material 20 provided along the short side, and the long side of the substrate 13 on the substrate 12 side A mark 31 is preferably provided between the two.

When the mark 31 is provided in the vicinity of the short side of the substrate 15, the end of the adhesive material 20 provided along the short side on the substrate 14 side, and the long side of the substrate 15 on the substrate 14 side It is preferable to provide a mark 31 between and / or between the end of the adhesive material 20 on the substrate 16 side and the long side of the substrate 15 on the substrate 16 side. When the mark 31 is provided in the vicinity of the short side of the substrate 16, the end on the substrate 15 side of the adhesive material 20 provided along the short side, the long side of the substrate 16 on the substrate 15 side, and A mark 31 is preferably provided between the two.

  As shown in FIG. 2, the marks 31 provided on the long sides of the substrates 11 and 14 are made of arrows indicating the directions from the substrates 11 and 14 to the substrates 12 and 15, respectively. The marks 31 provided on the long sides of the substrates 13 and 16 are formed of arrows indicating the directions from the substrates 13 and 16 toward the substrates 12 and 15, respectively. When the marks 31 are provided on the short sides of the substrates 11, 12, and 13, it is preferable that the arrows indicate the directions from the substrates 11, 12, and 13 toward the substrates 14, 15, and 16, respectively. When the marks 31 are provided on the short sides of the substrates 14, 15, 16, it is preferable that the arrows indicate the directions from the substrates 14, 15, 16 toward the substrates 11, 12, 13. The shape and arrangement of the mark 31 are not limited to this.

  When the floor heating mat 1 is constructed, the adhesive 30 is applied linearly from the outer peripheral edge of the lower surface of the floor heating mat 1 toward the center side of the lower surface along these arrows.

An adhesive 30 is applied along each mark 31 to place the floor heating mat 1 on the floor base F, and an operator can apply an appropriate load (preferably 0.1-0. 5 kg / cm ² is particularly preferred when added 0.2~0.3kg / cm ^2), the adhesive 30 is appropriately pushed stretched adhesive absence area of the lower surface of the floor heating mats 1 and the press It is preferable that the thickness of the stretched adhesive 30 is approximately the same as the thickness t ₁ of the adhesive material 20. Thereby, at the time of construction, since the floor heating mat 1 is partially and immediately adhered to the floor base F by the adhesive material 20, the floor heating mat 1 is warped or displaced until the adhesive 30 is cured. Etc. are less likely to occur. Further, after the adhesive 30 is cured, the entire floor heating mat 1 is bonded to the floor base F substantially uniformly.

In order to obtain such effects, the viscosity of the adhesive 30 is important, and the viscosity of the adhesive 30 is 5 to 70 Pa · s, particularly 8 to 60 Pa · s, particularly 12 to 50 Pa · s at 23 ° C. It is preferable. If the viscosity of the adhesive 30 is excessively low, when the floor heating mat 1 is placed on the floor base F, the adhesive 30 spreads too much and the thickness of the adhesive 30 becomes thinner than that of the adhesive material 20, The adhesive 30 may not be sufficiently filled between the floor heating mat 1 and the floor base F. In addition, if the viscosity of the adhesive 30 is excessively high, the adhesive 30 is not easily stretched even if a load is applied to the floor heating mat 1 from above after the floor heating mat 1 is placed on the floor base F. For this reason, the thickness of the adhesive 30 becomes larger than the thickness t _{1 of} the pressure-sensitive adhesive 20, and the pressure-sensitive adhesive 20 is not sufficiently adhered to the floor base F, so that the adhesive force by the pressure-sensitive adhesive 20 cannot be sufficiently obtained. The floor heating mat 1 may be easily warped or displaced.

  As the adhesive 30, for example, a one-component moisture-curing urethane resin adhesive is suitable, but is not limited to this.

When applying the adhesive 30 of the preferred viscosity range described above, the lower surface of the floor heating mat 1 at suitable installation interval d ₂ of the along each mark 31, perpendicular to the orientation direction of the mark 31 (arrow) The width W ₂ (FIG. 6) of the adhesive 30 in the direction is preferably 10 to 50 mm, particularly 30 to 40 mm, and the maximum thickness t ₂ (FIG. 6) of the adhesive 30 is ₂ to 5 mm, particularly 3 to 4 mm. It is preferable that In addition, it is more preferable to use a multi-hole nozzle instead of a single-hole nozzle for applying the adhesive 30. In this embodiment, a four-hole nozzle is used.

By passing through the nozzle insertion portion 64 of the joint 60B, the forward side branch pipe connection nozzle 63 and the return side branch pipe connection nozzle 63 are made to have the same height without arranging the branch joints 60A and 60B one above the other. They can be arranged alternately. Thereby, since the installation height of branch joint 60A, 60B can be restrained low, even when a heating floor is constructed | assembled using the thin floor heating mat 1, the upper surface of branch joint 60A, 60B is a heating floor (floor finish). The branch joints 60A and 60B should be installed so as to be positioned at the same height as or lower than the upper surface of the material G) or so that the branch joints 60A and 60B do not protrude excessively from the upper surface of the heating floor. Is possible. Further, by combining the branch joints 60A and 60B in this way, the floor area required to install these branch joints 60A and 60B can be reduced.

[How to construct a heated floor using the floor heating mat 1]
Below, the method to construct | assemble a heating floor using the floor heating mat 1 is demonstrated below. The following method is an example, and the present invention is not limited to the following method.

  When a heating floor is constructed in a room, a forward main pipe 51 and a return main pipe 52 for circulating hot water from the boiler are drawn into the room through a ventilation port (not shown) provided on the wall K of the room. These are routed along the wall K to the vicinity of the floor base F. Next, the tip of the forward main pipe 51 is connected to the main pipe connection nozzle 62 of the forward branch joint 60A, and the tip of the return side main pipe 52 is connected to the main pipe connection nozzle 62 of the return side branch joint 60B. Are bound with band B. A wall decorative cover 53 (FIGS. 10 and 11) is attached to the wall K so as to cover these main pipes 51 and 52.

  When the floor area of the room is larger than the installation area of the floor heating mat 1, the thickness of the floor heating mat 1 is approximately the same as that of the substrates 11 to 16 between the floor mat installation planned area and the surrounding wall K. A dummy substrate (not shown) is distributed. Similarly to the floor heating mat 1, the dummy substrate is also bonded to the floor base F with the adhesive 30 and / or the adhesive material 20 provided on the lower surface.

  Further, a guide substrate 54 for guiding each hot water pipe 3 from the pipe lead-out portion 17 of the floor heating mat 1 to below the drawing position of the main pipes 51 and 52 of the wall K along the outer edge of the mat installation planned area. Distribute materials. On the upper surface of the guide substrate 54, a plurality of pipes (six in this embodiment) are accommodated in which one end side and the other end side of each hot water pipe 3 drawn from the pipe lead-out portion 17 of the floor heating mat 1 are accommodated. A groove 55 (FIG. 10) is provided. One end side (outward side) and the other end side (return side) of each hot water pipe 3 are alternately accommodated in these pipe accommodating grooves 55. A notch-shaped joint arrangement portion 56 in which the branch joints 60A and 60B are arranged is formed at the end of the guide substrate 54 located below the retracted position of the main pipes 51 and 52.

  The thickness of the guide board 54 is also substantially equal to each of the boards 11 to 16 of the floor heating mat 1. That is, also in this guide substrate 54, each pipe accommodation groove 55 is exposed on the lower surface of the guide substrate 54. A backing material 57 (FIG. 11) is provided on the lower surface of the guide substrate 54 so as to close the bottom of the pipe housing grooves 55. The backing material 57 of the guide substrate 54 is the same as the backing material 18 of the floor heating mat 1. Similarly to the floor heating mat 1, the guide substrate 54 is also bonded to the floor base F with the adhesive 30 and / or the adhesive material 20 provided on the lower surface.

  Note that the dummy substrate and the guide substrate 54 may be made of the same material as the substrates 11 to 16 of the floor heating mat 1 or may be made of different materials.

  After making preparations as described above, the folding body of the floor heating mat 1 is carried into the room, the folding is released, and the floor heating mat 1 is expanded. Next, the covering material 21 and the peeling prevention material 22 are peeled off from the adhesive materials 20 and the lower surfaces of the substrates 11 to 16 to expose the adhesive materials 20. Further, an adhesive 30 is applied to the lower surfaces of the substrates 11 to 16 in accordance with the marks 31. Next, as shown in FIG. 6, the floor heating mat 1 is laid in the mat installation planned area of the floor base F with the adhesive material 20 and the adhesive 30 facing down, and an appropriate load is applied to the entire floor heating mat 1 from above. . As a result, as shown in FIG. 7, each adhesive material 20 is bonded to the floor base F, and the adhesive 30 spreads substantially evenly in the adhesive-free area between the floor heating mat 1 and the floor base F. By curing the adhesive 30, substantially the entire lower surface of the floor heating mat 1 is bonded to the floor base F by the adhesive 30 and the adhesive material 20.

  Next, one end side and the other end side of each hot water pipe 3 drawn out from the pipe drawing portion 17 of the floor heating mat 1 are respectively connected to the main pipe 51 of the wall K along the pipe receiving grooves 55 of the guide substrate 54. Route to below the retracted position of 52. Next, one end of each hot water pipe 3 is connected to each branch pipe connection nozzle 63 of the forward branch joint 60A, and the other end of each hot water pipe 3 is connected to each branch pipe connection nozzle 63 of the return side branch joint 60B. These are bound by band B. These branch joints 60A and 60B are combined and placed in the joint placement portion 56 of the guide substrate 54 as shown in FIGS. 9 (b) and 9 (c) and FIGS.

  In this embodiment, after each hot water pipe 3 is routed along each pipe receiving groove 55 of the guide substrate 54, a soaking sheet 58 is disposed so as to cover the upper surface of the guide substrate 54, and the soaking sheet 58 is It adheres to the upper surface of the guide substrate 54 with an adhesive (not shown) or the like. The soaking sheet 58 on the top surface of the guide substrate 54 is the same as the soaking sheet 5 on the top surface of each of the substrates 11 to 16 of the floor heating mat 1.

  Next, the adhesive 40 is applied to the upper surfaces of the floor heating mat 1, the dummy substrate, and the guide substrate 54, and the floor finishing material G is laid thereon. In this embodiment, as shown in FIG. 11, the floor finishing material G is not distributed on the upper side of the joint arrangement portion 56 of the guide substrate 54. Instead, the joint arrangement portion 56 is provided from above the floor finishing material G. A floor decorative cover 59 is arranged to cover the floor. The lower end of the wall decorative cover 53 comes into contact with the upper surface of the floor decorative cover 59.

  Thereafter, the adhesive 40 is cured to construct a heating floor and complete the construction.

  In the method of attaching the floor heating mat 1 to the floor base F, since the floor heating mat 1 is attached to the floor base F with the adhesive material 20 and the adhesive 30, no nailing or screwing is required during construction. is there. Thereby, it is possible to significantly reduce the generation of noise during construction.

  In addition, in the method of attaching the floor heating mat 1 to the floor base F, a part of the lower surface of the floor heating mat 1 is bonded to the floor base F by the adhesive material 20 and the other part is bonded to the floor base by the adhesive 30. Bonded to F. The adhesive material 20 does not have to wait for curing like the adhesive 30, and a part of the floor heating mat 1 is immediately bonded to the floor base F. Therefore, it is possible to effectively prevent the floor heating mat 1 from being warped or displaced until the adhesive 30 is cured in the adhesive material-free region on the lower surface of the floor heating mat 1.

  As in this embodiment, it is convenient and preferable to use a double-sided adhesive tape as the adhesive material 20. If a double-sided adhesive tape is used, the adhesive material 20 can be easily provided on the back surface of the floor heating mat 1.

  In this embodiment, the adhesive material 20 is covered with the covering material 21 from the time when the floor heating mat 1 is manufactured to immediately before the floor heating mat 1 is placed on the floor base F, and further the anti-peeling material 22 covers the covering material. Peeling from the adhesive material 20 of 21 is prevented. This prevents dust or the like from adhering to the adhesive material 20 when the floor heating mat 1 is stored or transported, thereby reducing the adhesive force of the adhesive material 20.

  In this embodiment, each board | substrate 11-16 of the floor heating mat 1 is so thin that the piping accommodation groove | channel 2 provided in each upper surface is exposed to a lower surface, and, thereby, the whole floor heating mat 1 is carried out. The thickness is also small. Therefore, the difference between the level of the floor on which the floor heating mat 1 is laid and the floor level of a room where the floor heating mat 1 is not laid can be kept small.

  In addition, since the floor heating mat 1 is small in this way, the floor level can be reduced even if a thick flooring material G laid on the floor heating mat 1 is used. It is prevented from becoming too high. Thus, by using what has a large thickness as finishing flooring G, the intensity | strength and rigidity of the constructed heating floor can be improved. Moreover, the freedom degree of selection of the finishing floor material G increases.

The foamed synthetic resin is preferably one in which the internal bubbles are closed cells from the viewpoint of heat insulation.

  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 upper surface of the soaking sheet, it is possible to prevent the soaking sheet from being damaged when the temperature control mat is packed or transported. The material of this film may be other than polyethylene terephthalate.

According to FIG. 2, a plurality of double-sided adhesive tapes having a thickness of 1.0 mm (# 530 made by Sekisui Chemical Co., Ltd.) are attached to the back side of the floor heating mat 1 at an installation interval of 450 mm. Adhesive 30 (urethane adhesive, viscosity 20 Pa · s (23 ° C.)) was applied at an installation interval of 150 mm so as not to overlap the double-sided adhesive tape, and the floor heating mat 1 was laid on the floor base F. Thereafter, a load of about 0.2 to 0.3 kg / cm ^{2 was} uniformly applied to the entire floor heating mat 1.

  No warpage or slippage of the floor heating mat 1 was observed until the adhesive 30 was cured. When the floor heating mat 1 was peeled off after the adhesive 30 was cured, the adhesive 30 was placed on the entire surface of the lower surface of the floor heating mat 1 between the adhesive material non-existing region and the floor base F. It was confirmed that it was spread almost evenly at the same thickness as the double-sided adhesive tape.
