本考案は、避雷導線の端部同志の接合が、端部
の固定用に用いられる避雷導線の伸縮吸収構造に
関する。[Detailed Description of the Invention] The present invention relates to a structure for absorbing expansion and contraction of a lightning conductor, in which the ends of the lightning conductor are joined together to fix the ends.
避雷導線はパラペツト上に直線状にして保持し
て用いられるものであるが、外気温度の変化によ
り熱的に伸縮するので、この伸縮を吸収するため
に第７図に示す様な伸縮吸収構造が用いられてい
た。 Lightning arrester conductors are used by being held in a straight line on a parapet, but they expand and contract thermally due to changes in outside temperature, so in order to absorb this expansion and contraction, an expansion and contraction absorption structure as shown in Figure 7 is used. It was used.
この従来構造は、弧状になつた織組銅線０２の
両端に、避雷導線４，４′の連結金具０３，０
３′が一体に固定されたもので、織組銅線０２の
曲率の変化により、伸縮を吸収するようにしてあ
る。 In this conventional structure, connecting fittings 03, 0 for lightning conductor wires 4, 4' are attached to both ends of the arc-shaped woven copper wire 02.
3' are fixed integrally, and expansion and contraction are absorbed by changes in the curvature of the woven copper wire 02.
この様な構成の従来品では、織組銅線０２は、
避雷導線のラインより大きく突出することとなる
ので、作業者がこの織組銅線０２に引掛かつた
り、あるいは、工具や器材が引掛かつて破損する
ような欠点が有つた。 In a conventional product with such a configuration, the woven copper wire 02 is
Since it protrudes far beyond the line of the lightning conductor wire, there is a drawback that a worker may get caught in the woven copper wire 02, or tools or equipment may get caught and be damaged.
本考案は、この様な欠点を解消することを目的
とする。 The present invention aims to eliminate such drawbacks.
この目的を達成するために、本考案の避雷導線
の伸縮吸収構造は筒状ケースの少なくとも一端部
に避雷導線連結金具が、筒中心線方向に相対移動
自在に内嵌され、該金具の内端に端部が固定され
た軟質部材が蛇行状にして前記ケース内に収納さ
れ、前記金具の固定箇所より離れた箇所で、前記
軟質部材が前記ケースに取付けられている構成を
採用したものである。 In order to achieve this purpose, in the expansion/contraction absorption structure of the lightning conductor of the present invention, a lightning conductor connecting fitting is fitted into at least one end of a cylindrical case so as to be relatively movable in the direction of the cylinder centerline, and the inner end of the fitting is A soft member having an end fixed thereto is housed in the case in a meandering manner, and the soft member is attached to the case at a location away from a location where the metal fitting is fixed. .
この構成により、軟質部材は筒状ケース内で避
雷導線の伸縮に連れ、伸縮することとなるため
に、筒状ケースを従来の織組銅線のように湾曲さ
せなくとも良好に伸線を吸収しえるようになつ
た。 With this configuration, the soft member expands and contracts as the lightning conductor expands and contracts within the cylindrical case, so it can absorb wire drawing well without having to bend the cylindrical case like conventional woven copper wire. I have become able to manage it.
このため、この伸縮吸収構造は、導線のライン
から大きく突出するようなことはなく、上記従来
欠点を解消しえるに至つた。 Therefore, this stretchable absorption structure does not protrude significantly from the line of the conducting wire, and the above-mentioned conventional drawbacks have been overcome.
又、軟質部材はケース内に収納されているか
ら、該軟質部材自身に自重に対する保形性を有す
る必要はなく、このため軟質部材として、自重に
比し軟らかいものを用いることができて、伸縮の
ときの抵抗を軽減し、一層良好に吸収作用を発揮
させ得るに至つた。 In addition, since the soft member is housed in the case, it is not necessary for the soft member itself to have shape retention properties against its own weight. Therefore, as a soft member, a material that is soft compared to its own weight can be used, and it can expand and contract. This resulted in a reduction in the resistance at the time of the drying process, and an even better absorption effect.
