Definitions

  • the invention relates to a tension bundle consisting of several tendons, which with are provided with a common casing.
  • Another object of the invention is a method for producing the jacketed Tension bundle.
  • the invention also includes an apparatus for performing the method.
  • the object of the invention is to avoid the disadvantage mentioned above to produce a coated clamping bundle, in which the covering is made using simple means can be applied to the tension bundle without high costs.
  • This object is achieved in that the bundle of tendons of a flexible slotted plastic tube or hose is enclosed, the Butt surfaces are welded.
  • the tube is at least at two longitudinal points preferably slit or cut open at least on the end side along the generatrix.
  • the tendons consist of sheathed Monostrands.
  • the plastic tube or the Plastic hose leaving a tight space between the tendons.
  • the spaces between the tendons are in the casing with cement, plastic, a fat-like mass or the like. Filler, filled out.
  • the jacketed tendon is made in such a way that according to the invention commercially available plastic pipe or a commercially available hose lengthways cut open or slit open and expanded in the area of the cut surface in the thus formed open slot the tendons are inserted, whereupon the plastic tube or the plastic hose is closed and the closing joint is welded together.
  • the plastic tube or Plastic tube after cutting or slitting only in the area of it Elasticity expanded by mechanical pressure on the cutting or slitting surface, so that the tube closes elastically again after the pressure has ceased.
  • a device for carrying out the method, which According to the invention, one device in succession in the longitudinal direction e.g. Rollers, for Guidance of a plastic tube or a plastic hose, a cutting device, e.g. a rotating knife disc or the like. for cutting the plastic pipe or the Plastic hose in the longitudinal direction of the same, a device for expanding the slotted tube or hose, a device for inserting the tendons in the cut tube or in the cut tube and a device for Welding the slot or the incision of the hose together.
  • the device shown in FIGS. 2a and 2b in a simplified representation has on one extending frame 1 or table or the like.
  • a drive device 2 for guidance a commercially available arbitrary length plastic tube 3, which in the present case is elongated with rounded ends, and preferably lying parallel to each other Tendons 4, in the form of a bundle of individual wires, strands, monostrands or the like, the at most, as shown in FIG. 1, with a corrosion protection 5 in the form of grease, one Plastic sheathing or the like. can be provided.
  • the tension members 4 and the plastic tube 3 there is a common drive for the tension members 4 and the plastic tube 3 provided in in the present case consists of several successive vertical rollers 2A, which are rotatably mounted, at least one of them, preferably the output side, is driven.
  • the drive rollers 2A guide the tension members 4 above the Plastic tube 3, so that the plastic tube 3 and the tension members 4 with the same Speed in the direction of arrow A can be moved over one another, as in Fig. 3a is shown.
  • rollers 6 Following the drive device 2 are superimposed rollers 6, rollers or the like. to guide the plastic tube 3 a subsequent as rotating Knife disc trained cutting device 7 is provided, which the high Plastic pipe, as Fig. 3b shows, cuts open at the apex of its rounded end.
  • a splitting or folding device 8 is provided through which the incision or gap 9 of the plastic tube 3, as shown in FIG. 3C, is expanded.
  • the expansion expediently takes place only in the area of the elasticity of the Pipe material.
  • a Deflection channel 10 is provided, which deflects the tendons 4 down and through the widened slot 9 introduces into the plastic tube 3, whereupon the tube 3 conditionally by the spring force and then, as illustrated in Fig. 2b, by a Welding device 12 is welded shut, so that a clamping bundle according to FIG. 3d is created.
  • the arrangement of the device for supplying cement can also before Welding device may be provided.
  • At least one feed lance can be used to introduce the filling material be provided before welding the cut or gap 9 in the Plastic tube 3 or the plastic tube is inserted so that this or this is led past the feed lances and filled with the filling material. She can do that Extend the lance up to or in the area of the weld or behind it. Instead of one such supply of the filling material, this can also be used as a prefabricated tape Tendons 4 in the cut or slit plastic tube 3 or in the cut or slit plastic tube are inserted.
  • drive rollers 13 can be provided, which the finished Feed the tension bundle according to FIG. 3f to a reel (not shown).
  • Hiebei encloses the Jacket or the plastic tube 3 or the plastic tube preferably the Tendons with a narrow space left at most to the extent of Manufacturing tolerance.
  • a band-shaped tendon is shown and described, it lies but within the scope of the invention, any arrangement of several strands or wires or To enclose mono strands with a common plastic sheath, e.g. Tapes, at which are the centers of the strands in the corner points of a triangle or more superimposed rows of strands or the like. available.
  • a common plastic sheath e.g. Tapes, at which are the centers of the strands in the corner points of a triangle or more superimposed rows of strands or the like.
