Definitions

  • the invention relates to a tension rod for use as a strap for bridges, the Middle part made of fiber composite material and its ends made of metallic material consist.
  • Fiber materials have high stiffness and relative to their specific density Strength. This property makes them particularly suitable for lightweight applications interesting. Advantages arise in particular if you look at the fiber in its longitudinal direction can claim on train.
  • Components of this type are usually from locally concentrated forces which often have different directions in the room.
  • the object of the invention is to use a tension rod made of fiber composite material as a strap for mobile bridges. This object is achieved according to the invention solved by the subject of the main claim; which relate to subclaims advantageous embodiments of the invention.
  • Fig. 4 is a plan view of each of the belts shown above.
  • FIG. 1 shows a tension rod 2 as a single belt 4 , the middle part of which is made of fiber composite material 6 and the end parts 8 are metal ashes 10 , each of which has a bore or an eye 12 (FIG. 4) .
  • Metal ash 10 and fiber composite material 6 are connected to one another by means of a glued shaft 14 (adhesive connection).
  • 1 and 2 each show a single belt 4 with a facing CFRP composite facing one another.
  • the double belt 16 of FIG. 3 is produced by gluing the individual belts of FIGS . 1 and 2 .
  • the two individual belts 4 of FIGS. 1 and 2 are basically the same.
  • the differently extending shaft 14 is achieved by rotating the belt 4 from FIG. 2 about the longitudinal axis relative to the belt 4 from FIG. 1 .
  • FIGS. 5, 6 and 7 sections along A - A, B - B and C - C are shown in FIGS. 5, 6 and 7 .
  • the shaft area 18 is substantially longer than the thickness of the tension rod.
  • the shaft area is 50 times longer than the thickness of the tension rod.
  • the shafts run out in a cutting shape.
  • Fig. 8 a Mehrfachgurt 20 is shown, which is glued three double straps of Fig.3. 9 shows a section in the region of the shaft 18 .
  • An embodiment of a typical single belt 4 of FIG. 1 or 2 has one Thickness of 10 - 20 mm, a width of 130 - 200 mm and a length of 5 - 10 m.
  • the fiber composite mainly consists of longitudinally oriented carbon fiber with thermosetting Epoxy resin matrix.
  • the metal fittings are made of steel, titanium or Aluminum.
  • the thermosetting adhesive on the carrier fabric is used as an adhesive connection min. 120 ° C system used.
