本考案は、流動棚や駆動ローラコンベヤ等の樹脂被覆鋼管構造体の一部を構成 する導電性樹脂被覆鋼管に関する。 The present invention relates to a conductive resin-coated steel pipe forming a part of a resin-coated steel pipe structure such as a fluidized shelf or a drive roller conveyor.

従来、この種の導電性樹脂被覆鋼管としては、静電気の帯電を防止するため、 薄肉鋼管（例えば、肉厚約０．７ｍｍのＳＰＣＣ−１）の表面全面に、導電材料 であるカーボンブラックを添加した導電性合成樹脂を、約１ｍｍの厚さに接着被 覆した直径２８〜３２ｍｍのものが知られている。 Conventionally, as this type of conductive resin-coated steel pipe, carbon black, which is a conductive material, has been added to the entire surface of a thin-walled steel pipe (for example, SPCC-1 with a wall thickness of about 0.7 mm) in order to prevent electrostatic charge. It is known that the conductive synthetic resin described above is adhered and coated to a thickness of about 1 mm to have a diameter of 28 to 32 mm.
【０００３】[0003]
しかしながら、従来の導電性樹脂被覆鋼管では、カーボンブラックが高価であ り、かつ黒色であるので、コスト高となり、かつ美観を損なうと共に、導電性合 成樹脂が耐衝撃性に劣るので、被覆樹脂が損傷し易い不具合がある。 そこで、本考案は、コストの低減を図り、かつ美観を高め得ると共に、被覆樹 脂を丈夫とし得る導電性樹脂被覆鋼管の提供を目的とする。 However, in the conventional conductive resin-coated steel pipe, carbon black is expensive and black, which increases the cost and impairs aesthetics, and the conductive synthetic resin is inferior in impact resistance. Has a problem that it is easily damaged. Therefore, an object of the present invention is to provide a conductive resin-coated steel pipe which can reduce the cost, enhance the aesthetic appearance, and make the coated resin durable.

前記課題を解決するため、本考案の導電性樹脂被覆鋼管は、樹脂被覆鋼管の被 覆樹脂の表面に、樹脂被覆鋼管の長手方向へ伸びる帯状の導電性合成樹脂が一体 形成されていることを特徴とする。 前記帯状の導電性合成樹脂は、５〜１５ｍｍの幅であることが好ましい。 又、前記帯状の導電性合成樹脂は、被覆樹脂の厚さの約１／３〜３／４の厚さ であることが好ましい。 In order to solve the above-mentioned problems, in the conductive resin-coated steel pipe of the present invention, a strip-shaped conductive synthetic resin extending in the longitudinal direction of the resin-coated steel pipe is integrally formed on the surface of the resin covered with the resin-coated steel pipe. Characterize. The strip-shaped conductive synthetic resin preferably has a width of 5 to 15 mm. Further, it is preferable that the strip-shaped conductive synthetic resin has a thickness of about 1/3 to 3/4 of the thickness of the coating resin.

上記手段においては、静電気が帯状の導電性合成樹脂を経てアース可能となる 。 帯状の導電性合成樹脂の幅が、５ｍｍ未満であると通電不良を生じ易く、１５ ｍｍを超えると不経済となる共に、黒色が目立ち、美観を損ね、かつその損傷を 生じ易くなる。 又、帯状の導電性合成樹脂の厚さが、被覆樹脂の厚さ１／３未満であると通電 不良を生じ易く、３／４を超えると損傷を生じ易くなる。 一方、帯状の導電性合成樹脂は、被覆樹脂との共押し出しで形成される。 In the above means, static electricity can be grounded through the belt-shaped conductive synthetic resin. If the width of the belt-shaped conductive synthetic resin is less than 5 mm, poor conduction is likely to occur, and if it exceeds 15 mm, it is uneconomical, and black is conspicuous, and the appearance is impaired and the damage is likely to occur. Further, if the thickness of the belt-shaped conductive synthetic resin is less than 1/3 of the thickness of the coating resin, defective conduction is likely to occur, and if it exceeds 3/4, damage is likely to occur. On the other hand, the strip-shaped conductive synthetic resin is formed by co-extrusion with the coating resin.
