For example, as a floor heating panel for a joist method, that is, as a floor heating panel laid on a floor base material such as a litter board laid on a joist, FIG. 7 (a), (b) and FIG. There are those shown in 8 (a) and (b). As shown in the figure, the floor heating panel 50 includes a rectangular panel main body 51 and a planar heating element 54 having a self-temperature control characteristic built in the panel main body 51. Two power lines 55 and one ground line 56 connected to the body 54 are disposed so as to cross the panel body 51 in the short direction, and both ends of the power line 55 and the ground line 56 are arranged. Are connected to connectors 57 and 58, respectively.

The panel main body 51 is formed of a panel base material 52 having a heater housing recess 52a formed on the back side, and an MDF (medium fiber board) or the like that holds the planar heating element 54 in the heater housing recess 52a. The back plates 53a and 53b cover the heat generating area of the sheet heating element 54 except for the crossing portions of the power supply line 55 and the ground wire 56, respectively. Further, it is fitted and fixed in a fitting recess 52b formed in the panel base 52 that is slightly larger than the heater housing recess 52a.
[0004]
[Problems to be solved by the invention]
By the way, as described above, the floor heating panel 50 is formed from the MDF in which the planar heating element 54 housed in the heater housing recess 52a of the panel base material 52 is fitted into the fitting recess 52b of the panel base material 52. Since the thin back plates 53a and 53b are only held in the panel base material 52, the heat of the planar heating element 54 is easily released to the back side of the panel main body 51, and the floor heating panel 50 is discarded. If it is directly laid on the floor base material, the surface side of the panel body 51 cannot be efficiently heated, and a floor heating floor with good heating efficiency cannot be constructed.
[0005]
Therefore, when constructing a floor heating floor using the floor heating panel 50, the floor heating panel 50 is not directly laid on a floor base material made of a littering board or the like, but FIG. ), The floor heating panel 50 must be laid after the insulating sheet 61 is laid on the floor base material 60, and the floor heating floor cannot be efficiently constructed in a short time. There is.
[0006]
Then, the subject of this invention is providing the floor heating panel which can construct a floor heating floor efficiently in a short time, without laying insulating materials, such as a heat insulation sheet, on a floor base material. .

[Means for solving the problems and effects thereof]
In order to solve the above-described problems, the invention according to claim 1 is provided with a panel base material having a heater housing recess formed on the back surface side, and a soaking sheet disposed on the upper side, housed in the heater housing recess . In the floor heating panel including an electric heater and a back plate that closes the heater containing recess in a state where the electric heater is contained in the heater containing recess, the back plate is formed of a heat insulating material , A fitting recess into which the back plate is fitted is formed on the back side of the panel base material, the electric heater is fixed to the back plate in advance, and the heater housing recess is the fitting recess. smaller, the is formed inside the fitting recess, the peripheral portion of the back plate and the fitting recess is of also providing floor heating panel, characterized in that it is directly bonded and fixed. The back plate is not limited to the one that completely closes the heater accommodating recess, and may be one that substantially closes the heater accommodating recess leaving a part.
[0008]
In the floor heating panel configured as described above, since the back plate that closes the heater housing recess of the panel base material is formed of a heat insulating material, the back side of the panel base material from the electric heater housed in the heater housing recess Heat release to the surface is prevented, and the surface side of the panel substrate can be efficiently heated.
[0009]
Therefore, when constructing a floor heating floor using this floor heating panel, it is necessary to separately lay a heat insulating material such as a heat-insulating sheet on a floor base material made of a litter board or the like like a conventional floor heating panel. Therefore, the floor heating floor can be efficiently constructed and the construction cost can be reduced.
[0010]
In addition, when constructing a floor heating floor using this floor heating panel, as described above, since this floor heating panel can be directly laid on a floor base material made of a litter paste, etc., the floor base material Compared to the case of a conventional floor heating panel in which a heat insulating sheet has to be laid on the floor, the floor heating floor finish height can be lowered by the thickness of the heat insulating sheet.
[0011]
Furthermore, since the heat insulating material is generally lightweight, there is an effect that the entire panel can be reduced in weight as compared with a conventional floor heating panel in which a back plate is formed of a wood material such as MDF.
[0012]
Further, since the back plate and the electric heater is fixed in advance, when accommodating an electric heater with a backing plate to the heater housing recess of the panel substrate, by fixing the back plate to the panel substrate, the electric heater Therefore, the floor heating panel can be efficiently manufactured.
