Description

[Detailed explanation of the idea] This invention relates to a roof heater.

As shown in FIG. 1, a conventional roof heater has a main body 1 made of a synthetic resin sheet, a rubber sheet, etc., with a plurality of heating wires 3 arranged in parallel, leaving an end region 2 for nailing. .

4 is a terminal cover, and 5 is a power line.

The reason why the heating wire 3 is not attached to the nailing end region 2 is the first
As shown in the figures and FIG.
This is to prevent the nails 6 from coming into contact with the heat generating wire 3 and causing the heat generating wire 3 to be electrically connected to the roof when the roof heater is attached to the roof by driving the nails.

However, as a result of not attaching the heat generating wire 3 to the nailing end region 2, the following drawbacks occurred.

(1) As shown in Fig. 3, the main body 1 of this roof heater is manufactured by sandwiching the heating wire 3 between two main body constituent sheets 1a and 1b and pressing them together with forming rolls 7.8. ,
Since the thickness, tension, etc. of the part of the main body 1 where the heating wire 3 is inserted (heating part area A: shown in FIG. 2) and the nailing end area 2 are different, as shown in FIG. 4, When the main body 1 was manufactured, phenomena such as warping (the distance thereof is indicated by L) and waving occurred in the roof heater.

(2) As shown in Fig. 2, when a tensile force is applied to the main body 1 after fixing the main body 1 to the roof with the nails 6, the nailing end formed only of rubber or synthetic resin Area 2
There was a risk that it would break and fall off the roof.

Therefore, an object of this invention is to provide a roof heater that does not cause warping or corrugation, and whose nailing end does not break due to tensile force.

An embodiment of this invention will be described with reference to FIGS. 5 and 6.

That is, as shown in FIGS. 5 and 6, this roof heater has a reinforcing wire having the same thickness and shrinkage rate as the heating wire 3' in the nailing end region 2' of the main body 1'. 9 are attached parallel to the heating wires 3' and at approximately the same pitch as the arrangement pitch of the heating wires 3'.

The reinforcing wire 9 has a certain degree of strength regardless of heat generation, and is made of, for example, a glass wire sealed with silicone rubber, or a simple metal wire.

Since the other configurations are the same as those of the conventional example, the same parts will be given corresponding symbols and their explanation will be omitted.

Since it is configured as shown in 2, you can enjoy the following effects.

That is, (1) by attaching the reinforcing wire 9 in the nailing end region 2', the strength becomes the same as if the heating wire 3' was placed on the entire surface of the main body 1', that is, the heating part area A ′ and the nailing end region 2′ are almost equal, it is possible to prevent phenomena that adversely affect the roof heater, such as warping and corrugation during manufacturing, and to make the overall thickness uniform. .

(2) The strength of the nailing end region 2' can be increased by the reinforcing wire 9, and even if a tensile force is applied after the roof heater is installed on the roof, the nailing end region 2' will break and There is no fear of it falling off.

(3) The reinforcing wire 9 can be attached to the nailing end region 2' at the same time as the heat generating wire 3' is attached to the heat generating area A' of the main body 1', and the manufacturing process is also increased. There isn't.

As described above, the roof heater of this invention has the advantage that warping and waving do not occur, and the nailing end region does not break.
