A nut 14 is screwed at the front end of a threaded rod part 12 protruding above the base plate 3 of a J-bolt consisting of the threaded rod part 12 and a bent part 13 holding the supporting line (a), and a through hole 7 with/from which the front end of the bent part 13 of the J-bolt 2 engages/ disengages is formed at the base plate 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for laying a cable such as a telephone line spirally around a support wire (messenger wire) and arranging it immediately below the support wire to suspend the cable. The present invention relates to a metal fitting for fixing a spiral hanger for a cable to the support wire.

[0002]

2. Description of the Related Art A spiral hanger and a support wire are simultaneously held between a bent portion of a U-shaped bolt and the board by penetrating a threaded portion of a U-shaped bolt through a board. There is a so-called wire clip having a structure in which a nut screwed into the nut is fastened and maintained.

[0003]

In the above-mentioned prior art, the spiral hanger and the support wire having different directions are simultaneously held (at the same point), so that the circular shape of the spiral hanger is straightened. (If it is not corrected, it will not be securely fixed by elasticity)
Since a pair of nuts need to be screwed into a U-shaped bolt, the workability is poor, and sometimes the nuts are dropped, causing a risk.

The present invention has been made by focusing on the drawbacks of the conventional example.

[0005]

A first arm piece and a second arm piece are protruded from a substrate to form a main body of a metal fitting, and are supported on the lower surface side of the distal end of the first arm piece mainly of the metal fitting. A pair of holding parts for interposing a wire, and a pair of holding parts for interposing a spiral hanger on the lower surface side of the tip of the second arm part, respectively, are opposed to each other. A nut is screwed into the tip of the threaded rod part projecting above the board of the J bolt composed of a bent part holding the support wire.
A through hole through which the tip of the bent portion of the bolt is disengaged is provided in the substrate.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front view, FIG. 2 is a plan view, and FIG. 3 is a sectional view taken along line XX of FIG. 1 of the spiral hanger for a cable according to the present invention. is there.

A fixing bracket A according to the present invention is wound around a support line a, and fixes a spiral spiral hanger h used for suspending a cable C directly below the support line a to the support line a. In this embodiment, a metal fitting 1 and a J-bolt (a substantially J-shaped bolt) 2 are combined with each other.

The metal fitting body 1 has a first arm piece 4 on one end of the substrate 3 along the direction in which the support wire a is suspended, and an other end along the direction in which the spiral hanger h is suspended. In this manner, the second arm piece 5 is formed so as to protrude, and the substrate 3 is provided with a pair of through-holes 6 and 7 located on the near side and the separated side of the second arm piece 5 respectively. On the lower surface side of the distal ends of the arm pieces 4, 5, a pair of holding pieces 8, 8, 9, 9 are provided so as to bend both ends of the arm pieces 4, 5, respectively. The supporting line a is provided in the gap 10 between the holding pieces 8 on the side of the second arm, and the gap 11 between the holding pieces 9 on the second arm piece 5 side.
Are designed so that the hanger h can be clamped.

A through hole 6 provided in the base plate 3 of the metal fitting 1 and separated from the second arm piece 5 has a threaded portion 12 of the J-bolt 2 comprising a threaded portion 12 and a bent portion 13. Through the lower side of the substrate 2, and screw a wing nut (which may be a normal hexagonal nut) 14 onto the tip of the threaded rod portion 12 protruding above the substrate 3 to approach the second arm piece 5. As described above, the fitting main body 1 is combined with the J-bolt 2 so that the fixing bracket A of the embodiment is configured such that the distal end of the bent portion 13 of the J-bolt 2 is disengaged from the through hole 7 on the side.

The fixing bracket A is combined with the existing support wire a and the spiral hanger h so that the support wire a is present inside the bent portion 13 of the J-bolt 2, and the holding portion piece of the first arm piece 4 is attached. After the arm pieces 4 and 5 are arranged so that the support wire a is interposed between the holding pieces 8 and 8 and the spiral hanger h is interposed between the holding pieces 9 and 9 of the second arm piece 5, the wing nut 1
When the screw 4 is tightened, the support wire a and the spiral hanger h are pressed by the fixture A, and the spiral hanger h is fixed to the support wire a.

[0011]

The present invention has the configuration described above,
No need to correct the hanger of the spiral hanger, it can be fixed with the nut screwed into the J bolt,
In addition, there is no danger of the nut dropping, and the danger of falling can be avoided.

In addition, since the support line and the spiral hanger are each pressed by the arm piece, even if the spiral hanger is deformed on a straight line with respect to the tensile force generated in parallel with the support line, the spiral hanger is deformed. , And as a result, it is possible to provide a fixing bracket having excellent fixing strength.
