Definitions

  • the invention relates to a belt strap insulator element in the guying of radio masts with at least one insulator, which is encompassed on two opposite, 90 ° offset, segment-shaped surfaces by a respective segment-shaped insulator bracket, and the free ends of which are connecting elements to the adjacent insulator element or one End element are articulated.
  • the insulator bracket is fork-shaped at each end, a web-shaped steel segment being welded to an inner and outer bracket bracket, the inner bracket bracket forming the contact surface for the actual insulator.
  • the manufacture of such insulator brackets is very complex, which applies in the same way if such an insulator bracket is manufactured in one piece as a drop forging.
  • the cross bolt has an unfavorable load in the threaded part which is endangered by the notch effect. In any case, this has proven to be the weakest part in breaking attempts.
  • Webbing isolators according to the prior art are known from the company publication "Webbing isolators” from Rosenthaltechnik AG, Selb, Germany.
  • the object of the invention is to provide a solution which both enables a simpler and less expensive manufacture and also avoids the unfavorable loads described above.
  • the isolator bracket consists of a steel segment with a turned-out contact surface for the isolator, around which a bracket tab is welded, at the ends of which two tabs engage on both sides, which engage Form connecting elements with the adjacent insulator element or end element.
  • the steel segment is provided with a bulge at the ends of its welded zones with the bracket flap, essentially directed toward the bracket flap, in particular if this bulge is circular in the middle.
  • threaded bores can be formed at the ends of the turned-out contact surfaces of the steel segment for fastening rounded mounting brackets for the insulator.
  • a steel segment 1 is formed with a turned-out contact surface 1 a for the actual insulator 7 and is welded on its outer edge to a strap bracket 2, with partially circular bulges 12 being provided at the ends of its welding zones with the bracket strap.
  • bracket tab 2 At each end of the bracket tab 2, two connecting tabs 8 engage, each of which forms a connecting element to the adjacent insulator element or end element.
  • the design is such that a connecting bolt 4 passing through both lugs 8 of the connecting element and one end of the bracket lug 2 is held with an outer fixed counter flange 9 by a connecting bolt 5 penetrating the latter, which can be screwed into an internal thread of an inner loose counter flange 6.
  • the turned steel segment 1 is kept so short that due to the elimination of the previous inner bracket tab at the ends of the turned contact surfaces threaded holes 10 can be formed, by means of which rounded mounting brackets 3 for the insulator 7 can be attached by means of a fastening screw 11.
