Description

  TECHNICAL FIELD The present invention relates to an inter-pillar line hardware used when drawing a communication line or the like between electric poles into a general customer's house.

  For example, a hook groove of a hook metal fitting that is provided with a holding groove that engages one half side along the axis of the support line on one side of a pair of holding plates that are arranged to face each other and that is passed through through holes provided in both holding plates. A structure in which a nut is screwed to the part and both holding plates are fastened to each other so that the support wire engaged with the holding groove is held, and the retaining tool is locked to the hook part of the hook metal fitting. There is (for example, Patent Document 1).

Japanese Utility Model Publication No. 1-58231

  The conventional example adopts a configuration in which the support wire engaged between the opposing holding grooves is simply clamped and clamped with the hook plates and the nuts screwed on the hooks, and the holding plates overlapped with each other. When a support wire with a larger diameter than the set value is clamped (attached to the support wire), a gap is generated between both clamping plates, and the clamped state (attached state) is not stable, and therefore corresponds to the diameter of the support wire. The scope of application is limited.

  The present invention has been created with the object of providing an inter-column wire bracket that can be applied without inconvenience in response to some differences in the diameters of the support wires, paying attention to the above-mentioned drawbacks of the conventional example.

  On one side of a pair of sandwiching plates arranged opposite to each other, a sandwiching groove that engages one half side along the axis of the support line is provided, and the other half side corresponding to the one side of the sandwiching groove side A cross-sectionally provided semicircular engaging groove in which the semicircular cross-sectional ridges provided on the other opposing clamping side engage with each other, and a cross-section provided on the other clamping plate side on the other half side Each of the semicircular engaging grooves is provided with semicircular ridges that are engaged with each other, and between the engaging grooves and ridges of both sandwiching plates, between the one side and the other one side. A notch that engages a hook portion of a hook metal fitting that allows the threaded hook portion to pass through is provided in a through hole provided in the center, and a nut is screwed into the tip of the threaded flange portion that protrudes from the through hole. .

  According to the present invention, the pair of sandwiching plates can be rotated with the engagement grooves and the protrusions on one side engaged with each other, so that the diameter of the gap between the engagement grooves on the other side is adjusted. That is, the difference in the diameter of the support wire can be absorbed and used by being attached to support wires of various diameters.

  In addition, since one half of each sandwiching plate has the engaging groove and the other half has a protrusion, the pair of sandwiching plates can be configured in the same shape. Can provide inexpensive products.

  FIG. 1 is a perspective view showing a use state, FIG. 2 is a rear view, and FIG. 3 is a cross-sectional view taken along the line aa of FIG.

  The inter-column separating hardware A according to the embodiment is constructed by assembling a pair of sandwiching plates 1 and 1 having the same shape with each other by a hook fitting 2 and a nut 3 screwed to the hook fitting 2.

  The sandwiching plate 1 is formed of a metal plate having a rectangular contour shape, and is provided with a sandwiching groove 4 having a semicircular cross section on one side of the back surface, and a half of the other side corresponding to the one side of the sandwiching groove 4 side. A projecting strip 5 having a semicircular cross section is provided on the side, and an engaging groove 6 having a semicircular cross section substantially matching the semicircular section of the projecting strip 5 is provided on the other half side (the other side). At the center between the protrusion 5 and the engagement groove 6, an engagement notch 8 for engaging the hook part 7 of the hook metal fitting 2 is provided, and the other one side on the hook part 7 side and the holding groove 4 are provided. A through-hole 10 that penetrates the screw 9 of the hook metal fitting 2 is provided at the center of the intermediate portion with the one side.

  The hook metal fitting 2 is formed of a metal housing that is bent at one end side and has the hook portion 7 and the other end side as the screw portion 9. And the tip portion 7a of the hook portion 7 is formed in a straight line and arranged in parallel with the screw portion 9.

  And it arrange | positions so that the back surface (back surface) side of a pair of clamping plates 1 and 1 may face each other, and the protrusion 5 of one clamping plate 1 is made into the engaging groove 6 of the other clamping plate 1, or The engaging groove 6 is engaged with the other one of the protrusions 5, the threaded portion 9 of the hook metal fitting 2 is passed through the through holes 10, 10, the nut 3 is screwed to the tip, and one of the clamps is clamped When the protrusion 5 of the plate 1 is engaged with the engagement groove 6 of the other one of the sandwiching plates 1 and the engagement groove 6 is engaged with the other one of the protrusions 5, the sandwiching grooves 4 facing each other. , 4 is formed, and the support wire Ca portion of the self-supporting cable C is interposed in the engagement gap, and the nut 3 is tightened while maintaining the interposed state. The holding grooves 4, 4 are close to each other to hold the support wire Ca portion, and the post-column separating metal fitting A is assembled to the support wire Ca portion. Is performed retraction operations using the anchor device B that engages with the click portion 7.

  In addition, although the thing of illustration shows the usage example which used this hardware A for the support line Ca of the self-supporting type cable C, it is used by assembling it to a support line called a so-called messenger wire. The present hardware A can also be applied.
