Definitions

  • the present patent application relates to an anchoring element for anchoring in one Borehole in a subsoil, mentioned in the preamble of claim 1 Art.
  • the object of the present invention is therefore an anchoring element of the aforementioned To develop a type that avoids the aforementioned disadvantages.
  • the peculiarity of the anchoring element according to the invention is to provide an automatic drive for the mixing element or elements on the anchoring part which can be activated via a triggering means.
  • this measure results in considerable time savings, since he no longer has an additional device, such as. B. with a coupled to the load application part of the anchoring drilling machine to induce a rotary motion on the mixing elements to achieve mixing of the multi-component mortar.
  • the user can first insert a film or glass cartridge containing at least two pasty reaction components into a prefabricated borehole.
  • the anchoring element, such as. B. an actively mixing anchor rod is then inserted into the borehole and z. B. driven into the bottom of the borehole by means of a hammer.
  • the mortar cartridge is destroyed and the reaction components emerge into the borehole, where they are distributed.
  • the triggering agent such as. B. a locking pin, a locking ring, etc. can then be removed so that the mixing element or elements is set into a mixing movement via the automatic drive, which causes the reaction components to mix.
  • z. B be if a store for kinetic energy is provided, which acts as a drive for the mixing element or elements, or this with Energy supplied.
  • the memory can be used during the production of the anchoring element "loaded” and about the trigger, which also serves as a backup an early release of the stored kinetic energy are protected. The anchor is therefore immediately ready for use by the user.
  • the or each accumulator or energy accumulator can be designed as a spring element be pre-stressed during the production of the anchoring element, and with one end on the anchoring part and with its other end on the or the Mixing elements is set.
  • the setting on the mixing element or elements can be used directly, or indirectly with the interposition of one or more other components respectively. This measure makes the automatic configuration very simple Drive possible.
  • the spring elements can, for. B. spiral or coil springs.
  • the anchoring part of the anchoring means is circumferentially surrounded by a mixing sleeve on which the mixing element or elements are arranged. This measure ensures an even distribution of Mixing effect of the drive on the mortar components achieved. It can be an advantage also be if an anchoring means at the borehole end of the anchoring part is arranged, with which the anchoring part is fixed relatively rotationally fixed in the borehole can be.
  • B. ribs, humps, knob-shaped or scoop-shaped mixing elements can be arranged or embedded.
  • the Mixing elements can e.g. B. but also as simple breakthroughs of any geometry in the Wall of the mixing sleeve to be formed.
  • the anchoring element 10 shown there initially has one Anchoring part 12 which is made in one piece with a load application part 11. With the intended Use of the anchoring element 10 in a not shown here Borehole, the anchoring part 12 is generally entirely in the borehole, while the load application part 11 protrudes from it so that something can be fixed on it can.
  • the anchoring element 10 is essentially fixed in the borehole cohesive via a two- or multi-component mortar placed in the borehole. With regard to the introduction of the mortar, reference is made to the previous description directed.
  • Fixing means 17 with circumferentially arranged holding means 18, such as. B. a circumferential toothing arranged, which the fixing of the end portion of the anchoring element 10 in serves a borehole.
  • This fixing means can also be made in one piece with the anchoring part 12 be executed.
  • a mixing sleeve 15 is arranged circumferentially around the anchoring part 12, in the wall 16 of which, in the present exemplary embodiment, circular openings 13 are arranged as mixing elements.
  • a drive device 20 is arranged between the anchoring part 12 and the mixing sleeve 15, which can set the mixing sleeve 15 in a rotational movement relative to the anchoring part 12 when a triggering means 21 is actuated.
  • the drive device 20 contains two helical springs 23 which lie on the peripheral surface of the anchoring part 12 and are firmly connected to the ends 24 thereof. At the ends 25, on the other hand, the coil springs 23 are firmly connected to the mixing sleeve 15. Both coil springs 23 are preloaded and prevented from relaxing via the release means 21.
  • the trigger means in the form of the locking pin 21, by means of manual pulling out via its eyelet 22 from the hole in the anchoring part 12 and the two sides the mixing sleeve 15 pulled out, the spring elements relax, in the form of Coil springs 23, whereby the mixing sleeve 15 with the mixing elements 13 relative to Anchoring part 12 is set in a rotational movement around the anchoring part 12 becomes.
  • this automatic movement leads to a mixing of the reaction components.
  • FIGS. 4 to 6 show a second embodiment of an anchoring element according to the invention 10 shown. This differs from the one shown above Embodiment by the details given below.
  • the drive device 20 On the outer surface of the mixing sleeve 15 are mixing elements 13 'in the form of inclined Ribs arranged.
  • the drive device 20 instead of the coil springs, the drive device 20 'contains two coil springs 23 'on two sections of the anchoring part which are reduced in outside diameter 12 are arranged.
  • the ends 24 'of the coil springs are closed as in FIG. 6 remove, firmly connected to the anchoring part 12, while the ends 25 'firmly with the Mixing sleeve 15 are connected.
  • the anchoring element 10 is again in its ready-to-use position, reproduced with preloaded spring elements / coil springs 23 '.
  • the previous section is described in its entirety Description of Figures 1 to 3 referenced.
