北海道，東北，北陸地方などの寒冷地域では、冬季の積雪や道路の凍結によっ て交通事故が発生したり、交通遮断で生活物資の供給が途絶しやすい。また、凍 結道路や雪道を自動車で走行する場合、スパイクタイヤを取付けることが必要で あるが、このスパイクタイヤが路面を削り、その粉塵公害が問題となって一部地 域で使用が規制されたために道路の融雪が緊急課題になっている。 In cold regions such as Hokkaido, Tohoku, and Hokuriku regions, snow accidents and road freezes in winter can lead to traffic accidents and traffic disruptions can disrupt the supply of daily commodities. Also, when driving a car on a frozen road or a snowy road, it is necessary to install spike tires, but this spike tire scrapes the road surface, dust pollution becomes a problem and use in some areas is regulated. As a result, snow melting on the road has become an urgent issue.
【０００３】 道路の融雪という課題は、現在、各種のロードヒーターを 敷設することによって解決されつつある。ロードヒーターの一例として、絶縁プ ラスチックでシースしたニクロム線や銅−ニッケル合金線をすだれ状に組み立て た発熱ユニットが存在し、このユニットを道路施工の際におのおの電気接続して 埋設していくだけでよい。The problem of snow melting on the road is currently being solved by laying various road heaters. As an example of a road heater, there is a heat generating unit that is made by assembling an insulating plastic sheathed nichrome wire or copper-nickel alloy wire into a blind shape.Each unit is electrically connected and buried during road construction. Good.

前記の発熱ユニットでは、低温（１００℃以下）における平衡温度で温度が安 定しにくく、サイリスタなどの温度制御装置の設置によって敷設コストが高くな り、発熱に際して多量の電流が流れるのでアンペアブレーカを装備しても安全性 に問題がある。ニクロム線や銅−ニッケル合金線は、長年の使用によって酸・ア ルカリで腐食して断線する可能性があり、酸化老化についても定期的な検査と取 替えが必要である。 In the above-mentioned heat generating unit, it is difficult to stabilize the temperature at the equilibrium temperature at low temperature (100 ° C or less), and the installation cost is increased by installing a temperature control device such as a thyristor, and a large amount of current flows when heat is generated. There is a problem with safety even if equipped. Nichrome wire and copper-nickel alloy wire may corrode with acid / alkali and break due to long-term use, and periodic inspection and replacement are also necessary for oxidation aging.
【０００５】 また、ニクロム線や銅−ニッケル合金線などの金属を用い る代りに、棒状の非金属発熱体も提案されている。この発熱体は、ポリエチレン 樹脂の芯材の回りに導電性カーボン樹脂を形成し、さらに絶縁プラスチックのシ ースで被覆している。この発熱体は、芯材の回りに形成した導電性カーボン樹脂 が屈曲や加圧で損傷されやすく、その電気抵抗値を用途に応じて正確に設定する ことが難しいうえに、導電性カーボン樹脂自体が非常に高価である。Also, instead of using a metal such as a nichrome wire or a copper-nickel alloy wire, a rod-shaped non-metal heating element has been proposed. In this heating element, a conductive carbon resin is formed around a polyethylene resin core material and further coated with an insulating plastic sheath. In this heating element, the conductive carbon resin formed around the core is easily damaged by bending or pressing, and it is difficult to set the electric resistance value accurately according to the application, and the conductive carbon resin itself Is very expensive.
【０００６】 本考案は、道路や屋根に埋設する各種の融雪装置に用いる 新たな発熱体を提案するものであり、強度的に優れ且つ発熱表面積が大きくて熱 効率が高い棒状の繊維発熱体を提供することを目的としている。本考案の他の目 的は、電気抵抗値を用途に応じて正確且つ容易に設定できる棒状の繊維発熱体を 提供することである。本考案のさらに他の目的は、施工時の屈曲や加圧で損傷す ることが少ない並列接続の発熱ユニットを提供することである。The present invention proposes a new heating element for use in various snow-melting devices buried in roads and roofs. A rod-shaped fiber heating element having excellent strength, a large heating surface area, and high thermal efficiency is provided. It is intended to be provided. Another object of the present invention is to provide a rod-shaped fiber heating element whose electric resistance value can be accurately and easily set according to the application. Still another object of the present invention is to provide a parallel-connected heat generating unit that is less likely to be damaged by bending or pressure during construction.

【００２７】 この繊維発熱体１に、電圧７.５Ｖ，電流２Ａの直流電流をアン ペアブレーカなしで通電するとヒーター部が７０℃となり、その消費電力は１本 当り１５Ｗであって全体で７５Ｗ／ｍ2である。測定時の環境温度は２０℃であ るから、５０℃昇温したことになる。When a direct current with a voltage of 7.5 V and a current of 2 A is applied to this fiber heating element 1 without an amp breaker, the heater section becomes 70 ° C., and the power consumption is 15 W per wire, and the total power consumption is 75 W / m 2 . Since the environmental temperature at the time of measurement is 20 ° C, this means that the temperature has risen by 50 ° C.
