Definitions

  • the invention relates to a device for anchoring a rod-shaped tension member made of fiber composite material for use as an anchor element in foundation or mining, as a reinforcement element for concrete, in particular prestressed concrete or the like.
  • Tension members made of high-strength fiber composite materials have a lower specific weight, but above all a higher corrosion resistance. With regard to these properties, such tension members could therefore be used with advantage as anchor elements in foundations and mines, where aggressive water often occurs, which poses a risk of corrosion for steel tension members.
  • Tension members made of fiber composite materials also behave similarly to steel, i.e. they have an essentially linear stress-strain line. In contrast to steel tension members, they have no yield point; on the contrary, they break when their tensile strength is reached without previous plastic deformation. This property and, in contrast to their strength in the longitudinal direction of the fibers, only very low transverse compressive strength prevent the anchoring devices which are otherwise known and proven in the construction industry from being adopted directly.
  • Anchoring solely by frictional engagement is not only complex because it requires the generation of clamping forces to be effective; it is also problematic because the reliability of such anchoring depends in the long run on the materials used, in particular for the sprags, maintaining their properties for a long time. This cannot be guaranteed with certainty, especially if one takes into account age-related creep.
  • Anchoring by gluing has the disadvantage that more or less complex measures have to be taken to produce anchoring at specific points on the tension member, which require a not inconsiderable amount of work to be performed on site.
  • the invention has for its object to provide a way to be able to transmit the anchoring force by direct form and friction in the thread, even with a tension member made of fiber composite materials in the anchoring area, similar to a threaded bolt with nut, without impermissibly high stresses in the Tension member arise.
  • this object is achieved in that an anchoring element provided with a corresponding thread is screwed onto the tension member provided at least at the points provided for anchoring with continuous, thread-forming profiles running along a helix, and between the tension member and the anchoring element an intermediate layer made of a material is provided which, when overstressed, enables large deformations with a small increase in stress.
  • the material forming the intermediate layer can be applied to the inner surface of the anchoring element or can also be subsequently introduced into the intermediate space between the tension member and the anchoring element and completely fill this intermediate space.
  • the invention is based on the consideration that the rod-shaped tension member made of fiber composite material itself is provided with a thread-forming profile, that is to say has profiles which interact with corresponding profiles of an anchoring body in a form-fitting and frictional manner.
  • the basic idea of the invention is between the tension member and the anchoring body, more precisely between the mutually engaging profiles of these two Elements to provide a buffer layer as a plasticizing zone.
  • the properties of this buffer layer must be such that their strength is less than the strength of the fiber composite material on transverse pressure and that large deformations with a small increase in stress are possible under load from a certain compressive stress.
  • the intermediate layer therefore suitably consists of plastic, for example of a thermoplastic such as polyethylene, a thermoset such as epoxy resin or the like.
  • the intermediate layer can also consist of a swelling material which exerts a transverse pressure on the tension member.
  • the profiles of the tension member expediently form an asymmetrical trapezoidal thread, in which the thread ribs are wider than the thread fillets.
  • an anchoring force is transmitted, for example, from a steel nut via the buffer layer and the synthetic resin of the tension member to the fibers; there is therefore a sufficient chain of damping elements.
  • the anchor nut need not be made of steel either; for example, it can also be made from a correspondingly reinforced thermoplastic.
  • the anchor rod 1 shows a longitudinal section through the anchoring area of a rock anchor with an anchor rod 1 which is inserted into a borehole 2.
  • the anchor rod 1 consists of a fiber composite material of appropriate strength; it is provided on its surface with a profile that forms a thread 3.
  • An anchoring device is arranged at the air-side end of the borehole 2 to secure the excavation area 4.
  • a nut 5 is provided as an anchoring device, which is supported against an anchor plate 6, which in turn rests on the breakout surface 4.
  • Fig. 2 which shows only a small section in longitudinal section of the force transmission area between the anchor rod 1 and the anchoring nut 5, shows the arranged on the surface of the rod 1 thread 3 from cross-sectional trapezoidal ribs 7 and depressions 8.
  • the ribs 7 are wider than the depressions 8 in order to ensure proper transmission of the shear forces.
  • the thread 3 can be produced, for example, by applying a deformation pressure to the rod 1 from the outside in the radial direction during the hardening of the unidirectional fibers which envelop and adhere to one another, by means of which the depressions 8 are produced as impressions. As a result, the fibers are not cut up, but - as indicated in FIG. 2 - only deflected somewhat in their course.
  • the anchoring nut 5 screwed onto the anchor rod 1 is provided on its inner surface with a corresponding profile consisting of ribs 9 and depressions 10.
  • the inner surface of the anchoring nut 5 is coated with a coating 11 made of plastic, which follows the predetermined profile and in turn forms a thread that corresponds in shape and size to that of the anchor rod 1, so that the anchoring nut 5 can be screwed onto the anchor rod 1.
  • the anchor rod 1 also shown in FIG. 3 in a longitudinal section in turn has ribs 7 and depressions 8 which form a thread.
  • the anchoring nut 5 ' has a corresponding thread made of ribs 14 and recesses 15 therebetween.
  • a material 16 is introduced, for example injected, into the space between the anchor rod 1 and the anchoring nut 5', which must have the play required for screwing on , which completely fills the intermediate space and thus forms an intermediate layer 16.
  • a tensile force is applied to the anchor rod 1 in the direction of the arrow 12 with simultaneous support of the anchoring nut 5 ', there is again an increasing deformation of the intermediate layer 16 in the direction of force occur, which was attempted to indicate at 13.
  • the material of the intermediate layer 11 or 16 are materials which swell strongly and which additionally exert a transverse pressure on the anchor rod 1. This increases the interlaminar shear strength, which under certain circumstances can reduce the anchoring length.
