  • Friction anchors are rock anchors that have a longitudinally inwardly folded tube that is inserted into a wellbore and expanded by increasing the pressure inside the folded tube such that the outer surface of the tube abuts the inner surface of the wellbore and the anchor so sets down in the hole.
  • the front end of the expandable tube 1 is closed by an end sleeve 2.
  • the tube 1 has a substantially over its entire length (omega-like) inwardly folded wall ( Fig. 2 ).
  • the rear end of the tube 1 so the end adjacent to the opening of the borehole (the outer end of the borehole), passes through an anchor plate 3 and carries an inflation sleeve 4 with inflation hole 5.
  • About an attached to the inflation sleeve 4 adapter is under pressure standing fluid (in particular water) is introduced into the interior of the tube 1 and the tube 1 expanded by unfolding the longitudinal fold of the tube 1, so that the Reibrohranker is fixed in the borehole by friction and positive engagement.
  • the invention is based on the object to expand the uses of Reibrohrankern the aforementioned type while retaining the advantages of Reibrohrankern.

  • the sleeve-like sleeve at one end of the expandable tube of the Reibrohrankers can also be used to connect with the expandable tube an inflation adapter through which pressure fluid (water) from a pressure source for expanding the tube is passed into the Reibrohranker.
  • Reibrohranker sleeve-like sleeve can also be used to connect with the Reibrohranker after it has been widened and set in the ground, other components.
  • Such components can be screwed components, such as bolts, in particular screws, eye bolts / Augschrauben od.

  • the expandable tube connected to the inserted into the sleeve-like sleeve, in particular screwed over the rolled thread sleeve, z. B. welded, is.
  • this thread-free area of increased diameter does not have to be present if a round thread is present, since the fluid which widens the expandable tube, due to the tolerance of the round thread in the threaded area to flow to the radial opening in the sleeve attached to the expandable tube and can enter there into the expandable tube.
