本発明は、外周面に螺線状の突条が突設されている線条
をクランプするクサビ型クランプに関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a wedge-shaped clamp for clamping a filament having a spiral protrusion on its outer peripheral surface.
（従来の技術）
架空の送電線や地線では、風を原因とする騒音を発生す
ることがある。この騒音を防ぐために線条の外周面に螺
線状の突条を設けた線条を用いることがある。(Prior Art) Overhead power transmission lines and ground wires may generate noise caused by wind. In order to prevent this noise, a filament with spiral protrusions provided on the outer peripheral surface of the filament is sometimes used.
この螺線状の突条を設けた線条を線条溝に段差のない通
常のクサビでクランプすると、接触点が螺線状の突条の
頭部のみになるので滑り易い。If the filament provided with this spiral protrusion is clamped in the filament groove with a regular wedge with no steps, the contact point will be only at the head of the spiral protrusion, so it will easily slip.
このような滑りを防止するために、例えば、特開昭８０

てクランプしているものがある。In order to prevent such slippage, for example,
As seen in Japanese Patent Application Laid-Open No. 82009 and 1981-1219, an armor rod is wound in the depression between the spiral protrusions to make the cross-sectional shape of the filament circular. There are some things that are clamped.

かなければならないから、現地での線条設置工事は大変
なものになる。This winding work involves unwinding the filament from a drum and wrapping the armor rod around the filament at the location where the clamp is to be installed on the filament, which makes the filament installation work on site very difficult. Become.
この線条設置工事の労力を極力軽減したいというのが本
発明の課題である。It is an object of the present invention to reduce the labor involved in the wire installation work as much as possible.

The type clamp has a clamp body and a wedge body inserted into the insertion hole of the clamp body, and the inner surface of the clamp body has a female spiral groove that matches the spiral protrusion of the filament. It is a wedge-shaped clamp that is characterized by being engraved.

), and insert the wedge body (2) into the insertion hole (3) of the clamp body (+) with a wedge driving tool to form a filament (W). The wedge body (2) is integrally inserted and fixed into the clamp body (1). In addition,
When driving the wedge body (2) of the wedge-shaped clamp is completed, the wedge body (2) is firmly fixed, and the wedge body (2) is firmly fixed.
) will form a jumper wire by attaching the jumper fittings to the wires, so it is necessary to specify the location for attaching the wedge body (2) to the wire, but it is necessary to specify the location in the span between the steel towers. Since it is long, the filament (W) can be easily twisted, and even if the twisting is performed, the filament (W) is not affected in any way.
