Description

本発明は、ケーブルを支持するために電柱間に架設した支持線(所謂メッセンジャーワイヤーや自己支持型ケーブル)に巻き付けた螺旋状ケーブルハンガー(螺旋状態様の杆体で成る)の安定的な架設状態の維持を目的として、概し、その端部を前記支持線に固定するために用いる螺旋状ケーブルハンガーの支持線固定金具に関するものである。   The present invention provides a stable installation state of a helical cable hanger (consisting of a spiral-like casing) wound around a support line (so-called messenger wire or self-supporting cable) installed between utility poles to support a cable. For the purpose of maintenance, the present invention generally relates to a support wire fixing bracket of a spiral cable hanger used to fix an end portion of the end portion to the support wire.
一対の挟持片で構成し、該挟持片の対向面側に設けた係合溝の一方に支持線を、他の一方の螺旋状ケーブルハンガーをそれぞれ係合し、前期の挟持片をボルトとナットによって締付けるようにした構造のものがある(例えば、特許文献1)。   It is composed of a pair of clamping pieces, and a support wire is engaged with one of the engaging grooves provided on the opposing surface side of the clamping piece, and the other helical cable hanger is engaged with each other. There is a structure that is tightened by (for example, Patent Document 1).
特許第3181883号公報Japanese Patent No. 318183
前記の従来例は、互いに交叉方向に位置するハンガーと支持線を一対の挟持片で挟持するようにして螺旋状ケーブルハンガーを支持線に固定する構成を採るので、支持線部とケーブル部とで成る、だるま型の自己支持型ケーブルの支持線部に対するハンガーの固定手段としては不適当で、当該自己支持型ケーブルに螺旋状ケーブルハンガーを固定するには別途金具を用意しなければならない。   Since the conventional example employs a configuration in which the hanger and the support wire positioned in the crossing direction are clamped by a pair of clamping pieces, the helical cable hanger is fixed to the support wire. The hanger is not suitable as a means for fixing the hanger to the support line portion of the daruma-type self-supporting cable. To fix the spiral cable hanger to the self-supporting cable, a separate metal fitting must be prepared.
本発明は、自己支持型ケーブルに巻回支持させた螺旋状ケーブルハンガーを当該自己支持型ケーブル(の支持線部)に固定するに好適な、ケーブル用スパイラルハンガーの支持線固定金具を提供することを目的として創案したものである。   The present invention provides a support wire fixing bracket for a spiral hanger for a cable, which is suitable for fixing a spiral cable hanger wound and supported on a self-supporting cable to the self-supporting cable (support wire portion thereof). It was created for the purpose.
ボルトとナットで締め付けて支持線を下端部で挟持させて該支持線に取り付ける一対の挟持片と、一方の該挟持片の外側に前記ボルトを貫通させて該一方の挟持片とで螺旋状ケーブルハンガーを挟持する締付け片を備えたことを基本的手段とし、この基本的手段に締付け片の上端に、該締付け片と一方の挟持片との間に介在させる螺旋状ケーブルハンガーを係合させる切欠を設けた点を付加することにより螺旋状ケーブルハンガーを支持線になお一層確実に固定できるようにしたものである。   A pair of clamping pieces that are fastened with bolts and nuts to clamp the support wire at the lower end and are attached to the support wire, and a spiral cable between the one clamping piece and the bolt passing through the outside of the clamping piece. A notch for engaging a spiral cable hanger interposed between the clamping piece and one clamping piece at the upper end of the clamping piece is provided as a basic means with a clamping piece for clamping the hanger. By adding a point provided with a spiral cable hanger, the helical cable hanger can be more securely fixed to the support wire.
本発明によれば、一対の挟持片によって支持線を挟持させて該支持線に取付けるものであるから、自己支持型ケーブルを構成する支持線に対しても不都合なく取付けられ、しかも、構成上、単一なボルトとナットで締付ければ足りるから構造が簡単で、安価な製品を提供できる。   According to the present invention, since the support wire is sandwiched and attached to the support wire by the pair of sandwiching pieces, it can be attached to the support wire constituting the self-supporting cable without any inconvenience. Since it is sufficient to tighten with a single bolt and nut, the structure is simple and an inexpensive product can be provided.
