Definitions

  • the invention relates to a wire rope network according to the preamble of the claim 1.
  • wire rope nets also called safety nets
  • safety nets are usually used arranged between upright beams anchored in the ground and connected to the girders by wire ropes. You can these wire ropes are equipped with spring links or by rope brakes be led through to some of the energy of the impact on the network To record good things. Wire rope nets are also known are made up of rings.
  • the known wire rope networks have a considerable amount Weight and require a considerable amount Manufacturing effort.
  • the invention seeks to remedy this.
  • the Invention as characterized in the claims solves the task of a wire rope net for rockfall, Logging and avalanche barriers and a procedure to create the same, which is a savings allowed on the amount of necessary wire ropes and can be produced with little effort.
  • Figure 1 shows a section of a Wire rope net that consists of several together in the form of Mesh connected wire ropes 1,2,3, ... put together is. At their ends, the wire ropes 1, 2, 3, ... are through conventional connecting parts, loops, clamps, etc. which are indicated with the reference numerals 4 and 5, with each other connected.
  • the known wire ropes for Connection of the wire mesh with supports can, as from Figure 1 is clearly visible, through which Loops 6,7,8,9 of the top wire rope 1 through which Loops of the lowest (not visible) wire rope of the complete network, and through the outermost Loops 6, 10, 11 left and right (not visible) become.
  • the wire ropes 1,2,3 can be different be wavy, i.e. the individual stitches can be different Have shapes.
  • the preferred form is in Figure 3 shown. It can be seen that the The shape of the mesh is derived from a circular shape.
  • the Wire rope 1 is drawn in a solid line and the supplementary, Geometric part of the circular arc is indicated and dotted designated with the reference number 12. It can be seen that the head 13 of each stitch 14 has an arc with a Centering angle of more than 180 ° describes. Further it can be seen that the stitches are basically only one Mesh head, but have no mesh legs. Neighbors Stitches 14 thus close with their heads 13 directly to each other, the heads 13 each in point in opposite directions.
  • a first wire rope 2 is by means of a Shaping device for the waveform shown in Figure 2 reshaped so that the drawn heads 10.16, 17.18, ... arise.
  • a second Wire rope 1 shaped in the same way so that the heads 6,7,8,9, ... are formed.
  • the wire rope 1 pushed against the wire rope 2 and all heads 6,7,8,9, ... relative to the drawing level in Figure 2 from above through the heads 10,16,17,18, ... so the arrangement drawn in Figure 1 of the two wire ropes 1, 2 is reached.
  • a subsequent one Wire rope is then passed through the heads with the heads 6,7,8,9, ... and these processes are repeated with additional wire ropes until the complete Wire rope net is formed.
