を均一に加熱することが困難であった。To prevent or remove snow from accumulating on roads, parking lots, etc. It is known to lay down snow melting blocks with heaters embedded inside them (Japanese Utility Model Publication No. 50-32274). In addition, the present inventor first proposed a snow melting block using a carbon heating element as a heater, as disclosed in Japanese Utility Model Application Publication No. 63-65704. Carbon heating elements are made by kneading carbon powder and thermoplastic resin. Since the resin has the characteristic that when the temperature rises, the resin expands and the resistance increases, so it has the effect of automatically controlling the temperature. however. This had the problem that when it was bent, voids were generated and wires were easily broken in parts. Therefore, it was difficult to uniformly heat the surface of the snow melting block.
本発明は融雪を効率的に行うことができ，耐久性の優れ
る融雪プロソクを提供することを目的とする。An object of the present invention is to provide a snow melting process that can efficiently melt snow and has excellent durability.

融雪ブロックである。The present invention is a rod-shaped heater in which a block has a flexible and insulating core material in the center, and a carbon heating element formed by kneading carbon powder and a thermoplastic resin is insulated and coated with resin. This is a snow melting block that is characterized by being bent and arranged in a meandering manner.

く，このため，ヒーターを折り曲げて蛇行配置すること
により融雪ブロックに比較的均等に分布させることがで
き，ヒーターからの熱を融雪ブロック表面に均一に放散
することができる。Since a carbon heater with a core material is used as the heater, there is no possibility of forming voids or breaking the wire even when the heater is bent. Therefore, by bending the heater and arranging it in a meandering manner, it is possible to distribute the snow relatively evenly on the snow melting block. This allows the heat from the heater to be evenly dissipated onto the surface of the snow melting block.

The surface is colored mortar to create a beautiful appearance as surface mortar N7. It is good to provide various patterns. Moreover, even if the entire hardened body 8 is made of the same material, the upper part is covered with mortar. The lower part may be made of two or more materials, such as concrete. Although the shape of the cured body 8 is not particularly limited, it is preferable that the cross section of the lower part of the block is smaller than that of the surface, as shown in the example. With this structure, when multiple snow-melting blocks are laid out, there will be a gap at the bottom, allowing electrical cables to run through.
