DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow-melting roof material for a house.

[0002]

2. Description of the Related Art Heretofore, snow removal work in a snowfall area has been physically difficult and dangerous. Therefore, various methods have been devised for melting snow on the roof. As one of them, there is a method in which a hot wire or a heat pipe or the like is provided on a roof to melt snow while dropping it, or a method of mechanically scraping snow.

[0003]

However, when a hot wire is used, the running cost becomes high, and when a part of the hot wire is cut off, all the electricity is turned off, and the repair is very costly and troublesome. was there.
Further, in the case of a heat pipe, there is a disadvantage that the snow near the heat pipe is melted only by laying the heat pipe, and in the case of heavy snow, the snow is hollowed out. In addition, the mechanical method requires a large-scale device, and has a disadvantage that the degree of freedom in design and design of the roof is reduced. For this reason, Japanese Patent Application Laid-Open No. 2-186073 is disclosed. However, since this structure is formed by wet construction, there is a disadvantage that the construction period is long.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks, the present invention provides a heat-generating portion on at least one of the side edges of the back surface of a roofing member having a male-female connection structure formed on the side edges in the width direction. It is intended to provide a snow-melting roof material formed with the following.

That is, the synthetic resin sheet contains various plastic resins such as a PVC resin as a base, and carbon fibers are mixed therein. When electricity is led to a conductive wire through a lead wire, the carbon Heat is generated by the resistance of the fiber. Further, since the carbon fibers are mixed so as to overlap with each other, even if a part of the surface heating sheet is broken or cut, the heating of the other part is not affected at all.

The insulator sheet is made of a PVC film, a fluororesin film, an acrylic film, or the like, and exhibits effects such as surface protection, waterproofing, and electrical insulation by being laminated. The lead wire is connected to a power supply (not shown), and the entire surface heating sheet generates heat due to the resistance of the conductive carbon fiber, and the heat is transmitted to the roofing material B of the exterior portion, and the snow is mainly melted at the eaves portion. Will be performed.
