しかしながら、従来の路面の融雪構造は、既設路面を全壊した後、新たに路床と融雪構造を形成するため、工事期間が長く、設置費用も高額であったため、一般に普及しにくいという問題があった。   However, the conventional snow melting structure on the road surface has a problem that it is generally difficult to spread because the construction period is long and the installation cost is high because the snow melting structure is newly formed after the existing road surface is completely destroyed. It was.

また、従来の線状発熱体では、金属管を使用したシーズヒータのように折り曲げが自在にできなかったり、発熱体を細くすると断線や漏電等の故障が生じ易かったり、さらに熱効率が低いため、直径の大きい線状発熱体が用いられることが多かった。 In addition, the conventional linear heating element cannot be bent freely like a sheathed heater using a metal tube, or if the heating element is thinned, it is easy to cause a failure such as disconnection or leakage, and the thermal efficiency is low. A linear heating element having a large diameter was often used.

上記課題を解決するため、請求項1記載の発明は、線状発熱体であって、抵抗線と、抵抗線を内部に収容するポリエステル系エラストマーからなるシース材と、シース材内部に充填される耐熱絶縁体と、シース材外周を編組状に被覆するニッケルメッキ軟銅線からなるシールド材から構成されることを特徴とする。   In order to solve the above-mentioned problem, the invention according to claim 1 is a linear heating element, and is filled with a resistance wire, a sheath material made of a polyester elastomer that accommodates the resistance wire inside, and the sheath material. It is characterized by comprising a heat-resistant insulator and a shield material made of nickel-plated annealed copper wire covering the outer periphery of the sheath material in a braided shape.

また、請求項2記載の発明は、既設路面を利用した融雪構造であって、既設路面に複数の縦溝と、該縦溝を交差する少なくとも2本の横溝が掘削され、該縦溝及び横溝内に請求項1記載の線状発熱体が蛇行状に収容され、溝内及び既設路面上に遠赤外線を発生させる物質が混入されたモルタル又はコンクリートが流し込まれて形成される融雪路床が形成されていることを特徴とする。   The invention according to claim 2 is a snow melting structure using an existing road surface, wherein a plurality of vertical grooves and at least two horizontal grooves intersecting the vertical grooves are excavated on the existing road surface, and the vertical grooves and the horizontal grooves The linear heating element according to claim 1 is accommodated in a serpentine shape, and a snow melting road bed formed by pouring mortar or concrete mixed with a substance that generates far infrared rays into the groove and on the existing road surface is formed. It is characterized by being.

本発明の線状発熱体は、直径が細く、また折り曲げが自在であり、かつ耐久性も高いことから、従来の太い線状発熱体に比べて、既設路面に形成する溝をより小さいものとすることができる。   Since the linear heating element of the present invention has a small diameter, can be bent freely, and has high durability, the groove formed on the existing road surface is smaller than the conventional thick linear heating element. can do.

また、本発明の既設路面を利用した融雪構造によれば、既設路面を全壊することなく施工できるため、施工が容易で工事期間が短く、設置費用を安価にすることができる。   Moreover, according to the snow melting structure using the existing road surface of this invention, since it can construct without destroying the existing road surface, construction is easy, a construction period is short, and installation cost can be made cheap.

さらに、本発明の線状発熱体は通電効率もよく、またこれを利用した融雪構造においては、路床表面に遠赤外線を発生させるモルタル又はコンクリート層を設けていることから、ランニングコストが安価にも拘らず、効率のよい融雪を行うことが可能である。   Furthermore, the linear heating element of the present invention has good energization efficiency, and in the snow melting structure using this, the running cost is low because a mortar or concrete layer that generates far infrared rays is provided on the road floor surface. Nevertheless, it is possible to perform efficient snow melting.

以下、本発明の線状発熱体及び既設路面を利用した融雪構造の実施の形態を、図面を参照して詳細に説明する。図1は、本発明の既設路面を利用した融雪構造の実施形態を示す断面図であり、図2は、本発明の線状発熱体を敷設した状態を示す図であり、図3は、本発明の線状発熱体の実施形態を示す斜視図である。   DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a snow melting structure using a linear heating element and an existing road surface according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a cross-sectional view showing an embodiment of a snow melting structure using an existing road surface of the present invention, FIG. 2 is a diagram showing a state in which the linear heating element of the present invention is laid, and FIG. It is a perspective view which shows embodiment of the linear heating element of invention.

図3に示すように、本発明の線状発熱体は、管状のポリエステル系エラストマーからなるシース材13内に抵抗線11が挿入され、シース材13内には耐熱絶縁体12が充填されるとともに、シーズ材13の外周はニッケルメッキ軟銅線からなるシールド材14が編組されて線状発熱体が構成されている。ここで、熱効率の見地から、抵抗線11としては、銅ニッケルが好ましく、耐熱絶縁体12としては、耐熱シリコンゴムとするのが好ましい。   As shown in FIG. 3, in the linear heating element of the present invention, a resistance wire 11 is inserted into a sheath material 13 made of a tubular polyester elastomer, and the sheath material 13 is filled with a heat resistant insulator 12. The outer periphery of the sheath material 13 is braided with a shield material 14 made of nickel-plated annealed copper wire to form a linear heating element. Here, from the viewpoint of thermal efficiency, the resistance wire 11 is preferably copper nickel, and the heat-resistant insulator 12 is preferably heat-resistant silicon rubber.

シールド材14としては、スズメッキ軟銅線等の他のものでもよいが、スズメッキに比べて耐熱性に優れ、防食効果が高いことから、ニッケルメッキ軟銅線とすることが好ましい。このニッケルメッキ軟銅線を編組することで、折り曲げが容易で、かつ耐久性の高い線状発熱体を得ることができる。   The shield material 14 may be other materials such as tin-plated annealed copper wire, but is preferably nickel-plated annealed copper wire because of its excellent heat resistance and high anticorrosion effect compared to tin plating. By braiding this nickel-plated annealed copper wire, a linear heating element that is easy to bend and has high durability can be obtained.

尚、線状発熱体5の直径は約5mmとするのが好ましく、このように従来より細いものであっても、前記構成により、耐久性や熱効率に優れた線状発熱体を得ることができる。 In addition, it is preferable that the diameter of the linear heating element 5 is about 5 mm, and the linear heating element excellent in durability and thermal efficiency can be obtained by the above configuration even if the diameter is smaller than the conventional one. .

また、本発明の既設路面を利用した融雪構造は、図1及び2に示すように、アスファルトやコンクリート等の既設路面1の表面に、まず、コンクリートカッター等により複数の縦溝3と、これと交差する少なくとも2本以上の横溝4を掘削される。縦溝3及び横溝4の大きさは、深さ30mm、幅6mm、縦溝の間隔は50〜100mmとするのが好ましい。   In addition, as shown in FIGS. 1 and 2, the snow melting structure using the existing road surface according to the present invention has a plurality of vertical grooves 3 formed on the surface of the existing road surface 1 such as asphalt or concrete by a concrete cutter or the like. At least two or more transverse grooves 4 intersecting are excavated. It is preferable that the vertical grooves 3 and the horizontal grooves 4 have a depth of 30 mm, a width of 6 mm, and a vertical groove interval of 50 to 100 mm.

掘削された縦溝3及び横溝4内には、前記構成からなる線状発熱体5が蛇行状に収容される。縦溝3及び横溝4内と既設路面1上には、遠赤外線を発生させる物質が混入されたモルタル又はコンクリートが流し込まれて融雪路床2が形成される。 融雪路床2内の遠赤外線を発生させる物質としては、トルマリンや炭素繊維が考えられるが、必ずしもこれらに限定されるわけではない。   In the excavated vertical groove 3 and horizontal groove 4, the linear heating element 5 having the above-described configuration is accommodated in a meandering manner. A mortar or concrete mixed with a substance that generates far-infrared rays is poured into the vertical grooves 3 and the horizontal grooves 4 and on the existing road surface 1 to form a snowmelt roadbed 2. As a substance that generates far infrared rays in the snow melting roadbed 2, tourmaline and carbon fiber are conceivable, but not necessarily limited thereto.

次に作用について説明する。まず、線状発熱体5に通電がなされると、線状発熱体5から熱が放熱されて融雪路床2が暖められる。融雪路床2が加温されると、融雪路床2内の遠赤外線発生物質から遠赤外線が発生される。このように、加温された融雪路床2の熱と放射される遠赤外線の効果により、融雪路床2上の雪が融雪される。   Next, the operation will be described. First, when the linear heating element 5 is energized, heat is radiated from the linear heating element 5 and the snow melting road floor 2 is warmed. When the snow melting road bed 2 is heated, far infrared rays are generated from the far infrared ray generating material in the snow melting road bed 2. Thus, the snow on the snowmelt roadbed 2 is melted by the effect of the heat of the heated snowmelt roadbed 2 and the radiated far infrared rays.

以上のように、本発明の線状発熱体と既設路面を利用した融雪構造によれば、既設路面を容易に融雪路面とすることができ、その融雪路面は非常に効率のよい融雪を行うことが可能である。   As described above, according to the snow melting structure using the linear heating element and the existing road surface of the present invention, the existing road surface can be easily made into a snow melting road surface, and the snow melting road surface can perform very efficient snow melting. Is possible.
