Instead of incorporating the second divided wiring cable 2b, the necessary number of first divided wiring cables 2a and one third divided wiring cable 2c may be used. Select appropriately according to the environment of the construction site. It is also possible to omit the third divided wiring cable 2c. In that case, a part corresponding to the third divided wiring cable 2c may be procured at the construction site.

  Next, an embodiment of the construction method of the electric floor heating floor according to the present invention will be described in more detail. FIG. 6 shows an example of the heater panel A used there. 6A is a rear view of the state where the backer material and the like are removed, and FIG. 6B is a cross-sectional view. In this example, the heater panel A has a groove 12 for a heater wire formed in a fixed pattern on the back surface of a wood substrate 11 such as a plywood, in which a heater wire 13 is embedded, and the wire heater 13 is electrically connected. The male connector 14 and the female connector 15 that are connected to each other are also disposed in a cut portion 16 formed on the back surface of the wooden board 11. Moreover, the thermostat 17 is arrange | positioned and the safety | security is ensured. A soaking layer 18 made of aluminum foil or the like is formed on the back surface of the wooden substrate 11, and a backer material 19 is laminated. The soaking layer 18 may not be provided.

  In constructing the electric floor heating floor, the sticking heater panel A1, the heater panel A, and the peripheral panel B are directly pasted on the concrete slab C as shown in FIG. The sticking heater panel A1 is obtained by removing one connector from the heater panel A shown in FIG. 6, and the peripheral panel B is a panel that does not have the heater wire 13. More specifically, the peripheral panel B is attached to one wall surface side, and then a sticking heater panel A1 is attached. Hereinafter, the necessary number of heater panels A are attached in multiple stages. Peripheral panel B is affixed to both sides. In this example, the heat transfer surface is divided into two sections, and two heater panels Aa and Ab are connected to each heat transfer section on the bottom side, that is, one side of the electric floor heating floor. It is arranged as a current intake. The heater panels Aa and Ab correspond to the heater panels Aa and Ab described with reference to FIG.

  In order to supply electricity from the commercial power source to the two heater panels Aa and Ab, the wiring cable 1 shown in FIG. 1 is used. In this example, there are two heater panels, heater panels Aa and Ab, located on one side of the electric floor heating floor, and therefore, one second divided wiring cable 2b and one first panel. The divided distribution cable 1a and the third divided distribution cable 2c are used.

  The packaging is opened, and one second divided wiring cable 2b, one first divided wiring cable 1a, and one third divided wiring cable 2c are taken out. The second connector 6 attached to the tip of the second divided wiring cable 2b is connected to the connector 15a attached to the heater panel Aa. Further, the second connector 6 attached to the first divided wiring cable 2a is connected to the connector 15b attached to the heater panel Ab.

  Next, the first connector 4 of the second divided distribution cable 2b is connected to the first connector 4 of the first divided distribution cable 2a, and the other first first of the first divided distribution cable 2a is connected. The first connector 4 of the third divided wiring cable 2c is connected to the connector 4. In this state, as shown in FIG. 5B, each power line 3 and branch line 5 are positioned at predetermined positions on the concrete slab C, and preferably temporarily fixed using an adhesive tape or the like. In this operation, the first divided wiring cable 2a and the second divided wiring cable 2b are short, and the lengths of the power supply line 3 and the branch line 5 are previously set in accordance with the lengths of the heater panels Aa and Ab to be used. Therefore, it is extremely easy and can be performed in a short time. Next, the long power supply line 3a of the third divided wiring cable 2c is guided to the wall 20 where the control box is located, and is connected to the relay box 21 through the back of the wall (see FIG. 5A).

  After the wiring work on the floor base surface (concrete slab C) of the wiring cable 1 is completed, the power supply line 3 and the branch line 5 are accommodated in the groove 10 formed on the back surface of the wiring panel B1. Paste it on the floor surface. Thereby, the construction on site is completed, and the electric floor heating floor shown in FIG. 5A is completed. As described above, the positioning of the power supply line 3 and the branch line 5 is reliably performed, and the work of attaching the wiring panel B1 is facilitated.

  In addition, as described above, the wiring work of the divided wiring cables and the affixing work of the wiring panel may be partially performed, so that accurate wiring of each divided wiring cable can be performed more quickly. it can. Further, in FIG. 5, the heater panel A, the wiring panel B1, and the like are rectangular, but this is for the purpose of simplifying the illustration, and a heater having a cocoon shape as shown in FIGS. The construction work is the same when using the panel A, the wiring panel B1, or the like.

  In addition, the backer material 19 is laminated on the back surface of the wiring panel B1 similarly to the heater panel A shown in FIG. 6, and the concave groove 10 is formed through the backer material 19. Further, as shown in FIG. 4, the concave groove 10 is preferably composed of two concave grooves 10a and 10b orthogonal to the longitudinal direction and the short direction of the wiring panel B1, and further, the longitudinal concave groove 10a. It is desirable to form a wide portion 10c for connecting the first connectors 4 and 4 of the divided wiring cable to a part of the cable. In this case, the length of the power supply line 3 of each divided wiring cable is set in advance so that the first connectors 4 and 4 of each divided wiring cable can be connected by the wide portion 10c. In this way, by providing the connection part between the divided wiring cables not in the peripheral part (sane part) of the wiring panel B1 but in the panel, it seems that the sink part feels sinking in the electric floor heating floor after construction. Inconvenience can be effectively avoided and a satisfactory tactile sensation can be obtained.

  In the above description, the groove is formed on the back surface only in the wiring panel B1 facing the lowermost heater panels Aa and Ab. However, the groove 10 is also formed on the back surface in the peripheral panel B at other locations. It may be left. Thereby, when the installation position of the relay box 21 is suddenly changed at the construction site, or when the attachment direction of the heater panel A is changed, the direction in which the wiring cable 1 runs is on the spot. It will be changed, but it will be easier to deal with it.
