Description

TECHNICAL FIELD The present invention relates to a heating panel used for floor heating and the like.

[Prior art and its problems]

The heating panel generally includes a heat equalizing plate on the front surface, a heating wire attached to the back surface thereof, and a heat insulating plate for preventing heat radiation to the back surface. Since conventional heating panels use plastic foam as a heat insulating plate, there is a risk of generating toxic gas in the event of a fire or the like.

In order to eliminate this, it is possible to use an inorganic foam as a heat insulating plate, but it is difficult to integrate the inorganic foam with the heat equalizing plate, peeling easily occurs, and cracking occurs when bending stress is applied. There are problems such as being easy.

[Means for solving problems and their effects]

The present invention provides a heating panel that solves the problems of the prior art as described above, and has a structure in which a corrugated wire mesh is fixed to the back surface of a heat equalizing plate and a heating wire formed in a meandering shape. And a heat insulating plate made of an inorganic foam is formed on the back surface of the soaking plate so as to embed the wire mesh and the heating wire.

According to the above configuration, since the heat insulating plate made of the inorganic foam is reinforced by the wire netting, it is difficult for cracks to occur, and since the wire netting is fixed to the heat equalizing plate, the integration with the heat equalizing plate is good. is there.

〔Example〕

1 and 2 show a heating panel according to an embodiment of the present invention. In the figure, reference numeral 1 is a soaking plate made of a steel plate or the like, the periphery of which is bent at a right angle to form a side wall 2, and the tip edge thereof is bent at a right angle to the inside to form a reinforcing rib 3. That is, the entire heat equalizing plate 1 has a shallow box shape.

Reference numeral 4 denotes a corrugated metal mesh, which is fixed to the back surface of the heat equalizing plate 1 by welding. 5 is the weld.

A heating wire 6 is formed in a meandering shape, and is arranged on the back surface of the heat equalizing plate 1. The heating wire 6 is arranged so that the parallel portion of the meandering is housed in the concave portion of the corrugated metal net 4.
This makes it easy to position the heating wire 6.

7 is a thermostat for temperature control, and 8 is its lead wire. In this example, the thermostat 7 is also installed and positioned in the concave portion of the wire net 4.

Reference numeral 9 denotes a heat insulating plate made of an inorganic foam (for example, foam concrete containing glass fibers).
Wire net 4, heating wire 6, thermostat 7 and lead wire 8
Is formed to be embedded. 10 is a power cord.

The heating panel as described above is manufactured as follows.
First, as shown in FIG. 3 (a), the heat equalizing plate 1 is formed into a box shape, and the plate is installed inside out. Next, as shown in (b), a corrugated wire netting 4 is arranged on it and fixed by welding. Next, as shown in (c), the meandering heating wire 6 and the thermostat 7 are installed at predetermined positions. Finally, an inorganic foam material (for example, a mixture of concrete, a foaming agent and glass fiber) is poured into the box-shaped heat equalizing plate 1, and the whole is heated and pressed by a hot press to foam and cure the heat insulating plate. 9 is formed. That's it!

[Effect of device]

As described above, according to the present invention, since the heat insulating plate is made of the inorganic foam, it is safe because it does not generate toxic gas in case of fire. Moreover, since the wire mesh is embedded in the heat insulating plate, there is an advantage that it has high strength and is hard to break. Further, since the wire net is fixed to the heat equalizing plate, the heat insulating plate and the heat equalizing plate are strongly integrated, and there is an advantage that peeling hardly occurs.
