Definitions

  • the invention relates to a tension element, in particular for the suspension of Components, with a number of a wire strand, arranged in parallel Wires, which at their ends in one each on the End of the wire strand which is subjected to tensile forces is anchored, and a process for its production.
  • high demands are placed on the tension elements and their anchoring posed.
  • a standardized production is not possible because must be delivered on a project basis. Most of the time it takes in a project many different rope diameters, different lengths and different ones End connections, with many binding dimensions (e.g. for the many different short ropes) only shortly before assembly can be determined.
  • Spiral or stranded ropes or wire strands are used as tension elements used from a number of wires arranged in parallel.
  • the the latter have a higher breaking load than spiral ropes and draw high fatigue strength (so-called fatigue strength) and a high modulus of elasticity (without a complex, time-consuming, Stretching process that can be carried out on special tractors required is).
  • fatigue strength high fatigue strength
  • modulus of elasticity without a complex, time-consuming, Stretching process that can be carried out on special tractors required is.
  • they will be in the Anchored end of the wire strand exerted tensile forces, wherein the end connection through an elaborate wedge anchoring individual Wires.
  • Such an anchoring device which is quite complicated in its construction is for example in the generic DE-A-34 37 107 disclosed.
  • the present invention was based on the object a technically simple and inexpensive tension element of the type mentioned at the outset, which quickly anchors the Strands of wire in the end piece allows and still a high breaking load guaranteed.
  • breaking load loss due to the plastic deformation is only approx. 5%, which is less than the so-called stranding loss with spiral or stranded ropes, which usually reduce the breaking load by approx. Accounts for 10%.
  • the loss of stranding does not apply to straight wires. For a certain breaking load therefore makes the tension element lighter and also cheaper.
  • the production of the tension element according to the invention is also easier, not only because the winding and stranding processes are omitted, but also in that no stretching process to achieve a required modulus of elasticity is necessary, but above all due to the simple type of anchoring. This enables simple project-related production and fast To deliver.
  • a tension element 1 according to the invention comprises a wire strand 2, which consists of a number of straight wires 3 arranged in parallel. Depending on the breaking strength required, there are at least seven or even up to several hundred wires 3.
  • the material used is a galvanized or zinc / aluminum or similar coated steel, chromium-nickel steel or aluminum, so that no additional corrosion protection is required is. It goes without saying that wires made of high-strength steel with a nominal strength of approx. 1800 N / mm 2 can also be used.
  • the wire strand 2 is preferably made of wires 3 of the same diameter (e.g. 2 or 3mm) bundled, which makes enormous logistical and Manufacturing advantages arise (less warehousing, hardly Remaining quantities or even waste, lower purchase price, faster delivery dates, Etc.).
  • wires 3 are not in more detail in shown way through a wire 3 when unwinding from a wire spool pulled a straightener to get a perfectly straight shape. Then the wires are cut to length. The so prepared Wires are then bundled so that a wire strand 2 one circular cross section is formed.
  • bundling would result in a hexagonal cross section.
  • the distance judges depends on the wire diameter or the number of wires and is 500 to 2000 mm.
  • round cross-sectional shape Another possibility for retention that cannot be seen from the drawing the round cross-sectional shape would be a bandage made of one practically any material (paper, plastic, round wire, flat wire, etc.) This could possibly give a new architectural freedom Offer.
  • the wire strand 3 is with its wire strand end in a bore 7 of the End piece 6 or end fittings anchored, which with a corresponding Component is connected, and that exerted on the wire strand Absorbs tensile forces and transfers them to the component (it goes without saying also the other end of the wire strand, not visible from FIG. 1, in analog Anchored in another tail).
  • the end piece 6 or its part 6a for example, with a Be threaded, or as a conventional connector with an eyelet, fork or other fasteners be trained.
  • the end piece 6 is with a plastically deformable Provide sleeve 6b, in the bore 7, the round wire strand end is used and non-positively by radially pressing the sleeve 6b is held.
  • the ratio of the length of the through the sleeve hole formed cylindrical contact surface to the outer diameter of the wire strand 2 is optimally between 4 to 8. So for Example with a diameter of the wire strand of 16 mm the length the contact surface of the sleeve hole selected 90 to 100 mm.
  • the plastic deformations 9 are on the inside of the sleeve 6b illustrated for illustration. Of course you can too deform the wires to a certain extent when crimping.
  • the end piece sleeve can have the same strength with thin or higher strength wires can be achieved.
  • the simple manufacture of the tension element according to the invention is not just about costs advantageous, but it also brings great flexibility, i.e. the possibility a rapid, project-related production. Significant are also the technical advantages; warehousing of various Ropes are no longer necessary.
  • the tension elements 1 according to the invention are entirely suitable especially as stay cables or stay cables for a stay cable bridge 30, which is illustrated schematically here in partial representation.
  • a bridge 30 has a bridge floor 31, one or more vertical, for example anchored at the bottom of a river 38 or the like Support pillars 33 and a number of tension elements 1 with Wiring existing wire strands 2.
  • the tension elements are at the end 1 in anchorages 35 connected laterally to the bridge and looking forward to what is not explained in detail, as these anchors on themselves are designed in a conventional manner. In any case, these end fittings are 6 less massive compared to those of the prior art and can therefore be in an aesthetically pleasing relationship with the rest Parts are kept.
  • a bridge railing 36 can also be seen.
