An inter-column separating hardware A is composed of a hook metal fitting 1 and a pair of sandwiching plates 2 and 2 which are combined with the hook metal fitting 1 and have the same shape. The cable body Cb and the support wire portion Ca are integrated with each other via the mediator Cc, and are used by being exclusively attached to the daruma-type self-supporting cable C, but for supporting the cable exclusively in a separate body. In addition, the inter-pillar separating hardware can also be applied to support lines (so-called messenger wires).

  The hook metal fitting 1 is formed by extending a slightly U-shaped hook portion 4 on a square rooted head portion 3a of the screw collar portion 3, and the square root portion 3a 'of the square rooted head portion 3a is formed from the base portion to the screw collar portion 3a. The shape of the truncated pyramid gradually decreases in the tip direction, and engages with a rectangular through hole 5 provided at the center of the sandwiching plate 2.

  The sandwiching plate 2 has a notch 6 provided at the center of one end along the longitudinal direction (when the hook 4 is assembled with the tip end portion of the hook 4 of the hook fitting 1, and this engagement relationship causes the holding bracket B to The hook portion Ba is less likely to come off than the hook 4, and the notch 6 and the through-hole 5 provided in the center along the longitudinal direction along the width direction, and the inner surface 2 'is entirely flat. The outer surface 2 ″ is composed of a horizontal rectangular contour body having a semicircular arc surface having a semicircular cross section that is most bulged at the center along the longitudinal direction.

  In addition, since the contact surface of the nut 13 screwed into the screw hook portion 3 of the hook metal fitting 1 is narrowed by making the outer surface 2 ″ an arc surface, the nut 13 can be tightened firmly.

  At one end of the inner surface 2 ′ of the sandwiching plate 2 along the longitudinal direction on the side of the notch 6, an engaging ridge 7 having a semicircular cross section at the tip edge 7 a on one side with the notch 6 interposed therebetween, An engaging groove 8 having a concave cross section is provided on the other side so that the leading edge 7a of the engaging protrusion 7 can be engaged (the leading edge 7a is an engaging groove 8 provided on the other holding plate 2 facing the other. A self-supporting cable C on the other end side of the inner surface 2 'of the sandwiching plate, which is opposed to the one end on the side of the protrusion 7 to the engaging groove 8 through the through hole 5. A holding groove 9 that engages one half of the longitudinal direction of the support line Ca is provided along the longitudinal direction, and a part of the edge of the holding groove 9 on the end edge side of the holding plate 2 is cut out. In the longitudinal direction, the short concave portion 11A, the long convex portion 12B, the long concave portion 11B, and the short convex portion 12A are provided in this order from the one end side to the other end direction.
