  In such a floor heating structure, the upper floor board (surface board) is fixed to the lower floor board with nails or staples. At this time, the nail is driven between adjacent heat generating sheets so that the nail does not penetrate the heat generating sheet. Then, if a nail or staple accidentally penetrates the heat generating sheet, an electric leakage is caused. Therefore, an insulation test is finally performed to determine whether or not the electric leakage is present. Such an insulation inspection can be easily inspected in the case of a detached wooden house because the wood has electrical conductivity.

  However, in a concrete apartment house such as a condominium, it is common to support a floor board with an insulating support member, so that it is not easy to perform the above-described insulation test.

Accordingly, the present invention is Ru der aims at providing a floor heating structure which can be easily performed insulation test.

In order to achieve this object, the invention according to claim 1 is characterized in that a plurality of heat generating sheets having a surface of the heat generating sheet body covered with an insulating member are arranged on the lower floor plate at a predetermined interval, and the plurality of heat generating sheets are provided. Is covered with an upper floor plate, the upper floor plate is fixed to the lower floor plate with a fixing fitting penetrating the upper floor plate, and a conductive layer for detecting insulation resistance is provided on the surface of the insulating member. In addition, a conductive member that is in contact with the conductive layer of each of the heat generating sheets is provided, and when the insulation resistance of the insulation member is detected by an insulation resistance meter, it is connected to the detection unit of the insulation resistance meter. The floor heating structure is characterized in that the lead wire to be connected is connected to the conductive member .

According to the first aspect of the present invention, since the conductive member that contacts the conductive layer of each heat generating sheet is provided , the insulation resistance between the conductive portion of the heat generating sheet and the conductive layer is measured. By doing so, an insulation test can be easily performed.

In other words, by measuring the insulation resistance between the conductive layer of the heat generating sheet and the conductive member, the insulation inspection can be easily performed, so that the insulation resistance detection position can be easily set at an arbitrary position. Even when there are a plurality of sheets, insulation inspection can be performed with one conductive member.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  In FIG. 1, 10 is a reinforced concrete apartment house, 11 is a living room of the apartment house 10, 12 is a concrete floor of the living room 11, 13 is a partition wall of the living room 11, and 14 is an outer wall of the living room 11.

  A particle board (first lower floor board) 15 is horizontally supported via a support member 16 on the concrete floor 12 of the living room 11. As shown in FIGS. 2 and 3, a heat insulating material 12 a such as glass wool is disposed between the concrete floor 12 and the particle board 15.

  As shown in FIGS. 2 and 3, the support member 16 includes a support column 17 that can be adjusted in height and a vibration isolation member 18 made of an insulating material such as rubber or soft resin attached to the upper end of the support column 17. Have. A small and square support plate 19 is interposed between the vibration isolation member 18 and the particle board 15.

  On the particle board 15, as shown in FIGS. 1 and 2, a discard board 20 as a second lower floor board is disposed. The discarding plate 20 includes a narrow first discarding plate 20a provided in a portion on the outer wall 14 side, and a main second discarding plate disposed at a distance from the first discarding plate 20a. It has a tension plate 20b.

  As shown in FIGS. 1, 2, and 4, a wiring space 21 extending along the outer wall 14 is formed between the discarding plates 20 a and 20 b. A conductive tape (conductive member) 22 extending along the wiring space 21 is affixed on the end portion of the discarding plate 20b on the wiring space 21 side.

  As the conductive tape 22, for example, an aluminum tape can be used. However, the conductive tape 22 is not necessarily limited to the aluminum tape as long as it has conductivity, and copper or other conductive metal tape (or A metal plate), a non-metallic conductive plate made of carbon fiber, or a non-metallic conductive tape.

  In addition, a plurality of heat generating sheets (planar heat generating elements) 23 are arranged at a predetermined interval L on the discarding plate 20b. As shown in FIGS. 5 and 6, the plurality of heat generating sheets 23 constitutes a set of two heat generating sheet rows 23 </ b> A and 23 </ b> B. 5 and 6, for the sake of convenience of explanation, the interval between the heat generating sheet rows 23A and 23B is set larger than the interval L, but actually, the interval between the heat generating sheet rows 23A and 23B is also the interval L as shown in FIG. Is set to

  As shown in FIG. 8B, each heat generating sheet 23 includes a heat generating layer (heater member, heat generating sheet main body) 24 made of a heat generating material that generates heat when energized, and an insulating waterproof protective film ( Insulating members) 25, 26. As for this heat generating sheet 23, the insulating waterproofing protective film 25 side is mounted on the discarding board 20b. For the heat generating sheet 23, for example, a self temperature control type PTC (Positive Temperature coefficient) heater is used.

  Moreover, a conductive sheet 27 such as an aluminum foil (aluminum sheet) is attached to the outer surface of the insulating waterproof protective film 25 as a conductive layer as shown in FIGS. 8 (a) and 8 (b). Yes. The conductive sheet 27 may be a material other than an aluminum foil (aluminum sheet) or the like as long as the material has conductivity and high thermal conductivity. And the edge part of the longitudinal direction of this electroconductive sheet 27 is mounted on the electroconductive tape 22 on the disposal board 20b, and is contacting the electroconductive tape 22. FIG.

  Further, lead wires 28 and 29 connected to electrodes (not shown) for energizing the heat generating layer 24 in FIG. 8B are drawn from one end of the heat generating sheet 23. Connection plugs (male connectors) 28a and 29a are connected to the ends of the lead wires 28 and 29 as shown in FIGS. 9 (a) to 9 (c).

  Further, as shown in FIG. 1, a controller 30 is attached to the interior wall 13a of the partition wall 13 so as to be positioned on the wiring space 21 side. The controller 30 is connected to a power source 31 such as indoor wiring as shown in FIG. In the controller 30, a control board 30a is provided as shown in FIG. 6A.

  Note that one end of a lead wire 22a is connected to the conductive tape 22 as shown in FIG. The other end of the lead wire 22a is connected to an insulation resistance detector when measuring the insulation resistance.

  Further, as shown in FIG. 6, the controller 30 is connected to wirings 32 and 33 to the heat generating sheet row 23A and wirings 32a and 33a to the heat generating sheet row 23B. The wirings 32 (32a) and 33 (33a) are disposed in the wiring space 21 described above. T1 to T4 are connection terminals provided on the control board 30a, and wirings 32, 33, 32a, and 33a are connected to the connection terminals T1 to T4.

  As shown in FIG. 9A, lead wires 34 and 35 are connected to the wires 32 (32a) and 33 (33a), respectively, and female connectors 34a and 35a are connected to the lead wires 34 and 35, respectively. Yes. The connection plug 28a and the female connector 34a constitute a first coupler 36, and the connection plug 29a and the female connector 35a constitute a second coupler 37.

  In addition, the length of the lead wire 28 is formed longer than the length of the lead wire 29 by the length (dimension) of the connection plug 28a (29a). The length of the lead wire 35 is formed longer than the length of the lead wire 34 by the length (dimension) of the female connector 34a (35a).

  Thus, when the connection plugs 28a and 29a are connected to the female connectors 34a and 35a as shown in FIG. 9A from the state shown in FIG. 9B, the connection plug 28a as shown in FIG. 9C and FIG. The connection portion 36 to the female connector 34a and the coupler 37 of the connection plug 29a to the female connector 35a are shifted in the connection direction by the length of the coupler 36 (37).

  In this state, the exposed portions of the lead wires 28, 29 and 34, 35 and the connection plugs 28a, 29a overlap each other even if the couplers 36, 37 are brought to slightly overlap each other as shown in FIG. There is no contact.

  Accordingly, since a single insulating tape portion 38 is formed around the couplers 36 and 37 by winding many portions of the couplers 36 and 37 with the insulating tape at the same time, the winding tape workability (workability) is improved. ) Is good. Thus, the exposed portions of the lead wires 28, 29, 34, 35 and the connection plugs 28a, 29a are covered with the insulating tape portion 38. Such connection and winding of the insulating tape are performed for each heat generating sheet 23.

  Further, a flooring board (upper floor board) 39 is disposed on the plurality of heat generating sheets 23 connected in this manner as shown in FIG. 1, and the heat generating sheet 23 is covered with the flooring board 39. The flooring board 39 is fixed on the particle board 20b by a nail (fixing bracket) 40. The fixing bracket for fixing the flooring board 39 on the particle board 20b is not limited to the nail 40 but may be staples or the like.

  Next, the operation of the floor heating structure having such a configuration will be described.

  In such a configuration, since the conductive sheet 27 on the lower surface of each heat generating sheet 23 is in contact with the conductive tape 22, an insulation resistance meter that detects the insulation resistance of the lead wire 22a connected to the conductive sheet 22 is used. If the insulation resistance becomes a predetermined value (for example, 100 MΩ) or more when connected to the detection unit and measured (inspected), the nail 40 has not leaked through the heat generating layer 24 and the conductive sheet 27, so there is a leakage. I understand that there is no.

  Further, when the flooring board 39 is fixed on the particle board 20b by the nail 40, when the nail 40 penetrates the heat generating sheet 23, the nail 40 penetrates the heat generating layer 24 and the conductive sheet 27 of FIG. Therefore, the heat generating layer 24 and the conductive sheet 27 are electrically connected via the nail 40. In this case, the insulation resistance meter shows a resistance value lower than a predetermined value (for example, 100 MΩ) when the lead wire 22a is connected to the detection unit of the insulation resistance meter for detecting the insulation resistance and measured (inspected) It can be seen that the nail 40 has leaked through the heat generating sheet 23. Thus, when there is a leakage, the heat generating sheet 23 is replaced.

Further, when there is no leakage due to such measurement, the heat generation layer 24 generates heat by operating the controller 30 and energizing the heat generation layer 24 of the heat generation sheet 23. The heat generated by the heat generation spreads uniformly over the entire lower surface of the heat generation sheet 23 through the conductive sheet 27, so that the entire flooring board 39 can be heated substantially uniformly.
(Modification 1)
In the embodiment described above, the conductive tape 22 is pasted on the discarded tension plate 20b which is the lower floor plate, the conductive sheet 27 is pasted on the lower surface of the heat generating sheet 23, and the conductive sheet 27 is attached to the conductive tape 22. Although the example which made it contact from above was shown, it is not necessarily limited to this.

For example, the conductive sheet 27 is attached to the upper surface of the heat generating sheet 23, and the conductive tape 22 is disposed so as to straddle the conductive sheets 27 of the plurality of heat generating sheets 23, and the flooring board 39 is mounted thereon. Alternatively, the conductive tape 22 may be in contact with the conductive sheets 27 of the plurality of heat generating sheets 23 so as to be pressed. The conductive tape 22 may be attached in advance to the lower surface of the flooring board 39.
(Modification 2)
In the embodiment described above, the conductive tape 22 is brought into contact across the conductive sheets 27 of all the heat generating sheets 23, but is not necessarily limited thereto.

  For example, a conductive tape straddling the conductive sheets 27 of the plurality of heat generating sheets 23 in the heat generating sheet row 23A and a conductive tape straddling the conductive sheets 27 of the plurality of heat generating sheets 23 in the heat generating sheet row 23B are provided. It is also possible to measure the insulation resistance for each of the rows 23A and 23B.

Moreover, the detection terminals of the wirings of the conductive sheets 27 of all the heat generating sheets 23 can be provided on the control board 30a so that the insulation resistance can be detected for each heat generating sheet 23. In this case, a belt-like sheet provided with a number of printed wirings (the surface is covered with an insulating layer) corresponding to the number of the heat-generating sheets 23 is used, and each heat-generating sheet is formed on the surface of the insulating layer of the belt-like sheet. It is good also as a structure which provided the some contact part corresponding to 23 and each connected to each printed wiring. According to this configuration, since the insulation resistance can be measured for each heat generating sheet 23, when one of the heat generating sheets 23 is leaking, only the leaking heat generating sheet needs to be replaced.

Moreover, in the Example demonstrated above, although the example which applied the heat_generation | fever sheet | seat 23 to the floor of the apartment house 10 was shown, it is not necessarily limited to this. For example, it can be applied to the interior wall 13a. In this case, a sheet mounting board for mounting the heat generating sheet 23 is disposed between the interior wall 13a and the partition wall 13, and the heat generating sheet 23 is interposed between the sheet mounting board and the interior wall 13a, You may make it apply the same structure as the floor heating structure mentioned above.
