〔Example〕

 The present invention will be specifically described below with reference to the drawings.

FIG. 1 shows a cross section of a ceiling heating panel according to one embodiment,
FIG. 2 shows the plane of FIG.

In FIG. 1, a ceiling heating panel 1 includes a ceiling material 2 such as a gypsum board (plaster board), a metal plate 3 laid on the entire upper surface of the ceiling material, and an upper surface of the ceiling material 2 (in the illustrated example, the metal plate Spacers 4 arranged at the peripheral portion of the upper surface of the ceiling member 3) and at desired intervals, and the spacers 4 on the upper surface of the ceiling member 2 (the upper surface of the ceiling member 3 in the illustrated example). Sheet heating element 5 laid between
And a reinforcing plate 6 laid over the entire upper surface of the spacer 4 and the planar heating element.

This ceiling heating panel 1 is, for example, 910 mm × 1820 mm
The ceiling surface is formed by arranging a plurality of these and arranging them in combination with an ordinary ceiling panel or a similar ceiling heating panel as appropriate.

The ceiling material 2 forms a heat radiation surface, and for example, a gypsum board having a thickness of 9 mm, 12 mm or 15 mm is used.

The metal plate 3 is a good heat conductor having a high thermal conductivity and is for transferring the heat of the planar heating element 5 to the ceiling material 2 quickly and uniformly to enhance the heat radiation effect, and has a thickness of 0.5 mm, for example.
Formed from a plate or foil of a degree of ferrous or non-ferrous metal. The metal plate 3 is fixed to the upper surface of the ceiling material 2 by adhesion or the like.

The spacer 4 has a function of forming an installation space for the planar heating element 5 and absorbing a difference in thermal expansion between panel components, and is made of, for example, resin foam such as expanded polyethylene, expanded polystyrene, or expanded polyurethane. Composed. The thickness of the spacer 4 is selected in consideration of the thickness of the sheet heating element 5 and is set to, for example, about 5 mm.

The spacer 4 is fixed to the upper surface of the metal plate 3 by adhesion or the like.

The sheet heating element 5 is a belt-shaped or sheet-shaped member that generates heat by passing electricity.

FIG. 3 is a view showing an example of this sheet heating element, which is a structure in which lead wires 8 for energization are embedded on both sides of a strip 7 of a thermoplastic resin or rubber mixed with conductive fine particles such as carbon. Have. In this structure, the strip 7 acts as an exothermic low antibody, and when a DC or AC voltage E is applied between the lead wires 8 as electrodes as shown in the figure, the lead wire 8 passes through the strip 7. A current flows between 8 and the strip heats up.

In this case, the amount of heat generation can be adjusted by adjusting the material and amount of the conductive fine particles mixed in the strip 7, and the lead wires 8 are buried over substantially the entire length of the strip 7. Therefore, it is possible to generate heat almost uniformly over the entire surface of the strip.

In FIG. 1, the reinforcing plate 6 is for ensuring strength and rigidity as a ceiling panel, and for example, a plated steel plate having a thickness of about 0.3 to 0.8 mm is used. The reinforcing plate 6 is fixed to the upper surface of the spacer 4 by adhesion or the like.

When constructing the ceiling heating panel 1 described above,
As shown in FIG. 1, the heat insulating material 10 is fixed to the upper surface of the panel 1 (the upper surface of the reinforcing plate 6 in the illustrated example) by adhesion or the like to suppress heat dissipation to the ceiling slab side and to the room (downward). The heat dissipation is promoted, and the heating efficiency is improved. As the heat insulating material 10, a suitable material can be used, and for example, a heat insulating material such as expanded polyethylene, expanded polyethylene, or expanded polyurethane can be used. It should be noted that this heat insulating material 10 is preferably installed on the ceiling panel when combined with a normal ceiling panel, because heat dissipation from the ceiling surface can be further reduced.

Further, since the upper and lower surfaces of the spacer 4 are joined to the metal plate 3 and the reinforcing plate 6, a double-sided adhesive tape in which a foam is used as the spacer and a pressure-sensitive adhesive and a separator layer are formed on both surfaces of the foam. By using, the assembling workability can be improved.

According to the embodiment described above, since the metal plate 3 having a good thermal conductivity is laid on the entire upper surface of the ceiling material 2 and the planar heating element 5 is laid on the upper surface thereof, the thermal efficiency of the planar heating element 5 is improved. At the same time, the temperature distribution of the ceiling material 2 could be made uniform.

Further, the spacers 4 are fixed to the upper surface of the ceiling material 2 (the upper surface through the metal plate 3) at predetermined intervals, and the reinforcing plate 6 having substantially the same size as the ceiling material 2 is fixed to the upper surface of each spacer 4 so that each spacer Since the sheet heating element 5 is housed in the space between, the ceiling heating panel that is light in weight, excellent in strength and rigidity, and easy in handling during construction is obtained.

Furthermore, since the spacers 4 are formed of resin foam, the thermal expansion of the panel structure can be absorbed, and even if the planar heating element 5 thermally expands, it can be held in a close contact state without difficulty. Became possible.

[Effect] As is clear from the above description, according to the present invention, in a ceiling heating panel in which a planar heating element is laid on the upper surface of a ceiling material made of a plate material having a predetermined size, a metal of a good thermal conductor is provided on the entire upper surface of the ceiling material. A plate is laid, and spacers of a predetermined height are fixed at desired intervals on the upper surface of the plate to form a planar heating element accommodating space between the spacers, and planar heating is performed between the spacers on the upper surface of the metal plate. Since the body is laid and a metal reinforcing plate of approximately the same size as the ceiling material is fixed to the upper surface of each spacer, the thermal efficiency of the planar heating element is improved and the temperature distribution of the ceiling material is made uniform. In addition, it is possible to obtain a ceiling heating panel that is lightweight and has a panel structure that is excellent in strength and rigidity.
