Definitions

  • the invention relates to a device for fixing fasteners according to the preamble of the main claim.
  • fastening elements For use in undercut boreholes, fastening elements are used which have an expansion element at their end inserted into the borehole, which is expanded by an expansion body in the region of the undercut of the borehole.
  • the expansion body can be designed as an expansion cone that can be drawn into the sleeve-shaped expansion element during the expansion process by rotating the shaft of the fastening element.
  • the expansion body can be connected to the shaft of the fastening element via a threaded rod and have an anti-rotation lock acting on the bottom of the borehole, so that when the shaft rotates, the expansion body does not rotate and is drawn into the expansion sleeve. This expands the expansion sleeve and engages in the undercut of the borehole.
  • Such a fastener is described in German patent application P 37 19 798.3.
  • the fastening element In order to fix such a fastening element in a borehole, the fastening element previously had to be driven into the borehole and then the expansion cone had to be drawn into the expansion sleeve by rotating the shaft with a suitable tool. Different tools were therefore required to create the borehole, to insert and anchor the fastening element.
  • the invention has for its object to provide a device for fixing fasteners that can be used in undercut boreholes, which allows fast fixing of the fasteners using a drilling device.
  • the device designed as an intermediate piece represents a rotationally fixed connection between the shaft of the fastening element and the drill inserted into a drilling machine, so that the torque emanating from the drill acts on the shaft of the fastening element via the intermediate piece.
  • a machine with a striking mechanism is preferably used as the drilling machine, so that the strikes transmitted from the striking mechanism to the intermediate piece also act on the shaft end of the fastening element and quickly drive it into the borehole down to the bottom of the borehole while rotating.
  • the expansion cone is now drawn into the expansion element as a result of the torque acting on the shaft of the fastening element, so that it expands in the region of the undercut.
  • the fastener is thus positively fixed in the borehole.
  • a further development of the invention provides that the drill tip forms an at least partially flattened end face which bears against a correspondingly flattened stop in the intermediate piece.
  • the intermediate piece can be designed as a sleeve which partially surrounds the drill shaft, so that the shaft of the drill thereby forms a guide for the intermediate piece.
  • the centering tube present on the drilling bell which largely surrounds the drill shaft, can engage in a corresponding inner bore of the intermediate piece and thus serve as a guide for the intermediate piece.
  • the intermediate piece in the area of the receptacle provided for the drill with slots or grooves in which the cutting edge of the drill tip engages laterally.
  • the drill shaft can be smooth and the drill tip can be formed by a hard metal cutting tool inserted at the end of the drill, which protrudes laterally on the shaft.
  • the cutting edge then preferably engages in the slots provided on the intermediate piece and thus transmits the torque emanating from the drill to the intermediate piece.
  • the second receptacle on the intermediate piece in which the end of the shaft of the fastening element engages, also forms a rotationally fixed connection between the fastening element and the intermediate piece.
  • an internal hexagon is provided on the intermediate piece, in which a corresponding hexagon which projects at the shaft end of the fastening element positively engages.
  • the second receptacle is a groove with an inwardly curved groove base into which a square formed on the shaft of the fastening element engages with an outwardly curved end face. The placement of the intermediate piece is particularly facilitated by this measure and the domed contact surfaces achieve an automatic centering between the fastening element and the intermediate piece.
  • the form-fitting connection between the shaft of the fastening element and the intermediate piece can ensure, by appropriately selected depth of this receptacle or by suitable shaping, that the connection in the region of the second receptacle is released at the end of the expansion process and the sudden increase in torque associated therewith.
  • a deformable intermediate ring can be arranged between the spreading element and the shaft of the fastening element value deforms.
  • this intermediate ring can consist of a more or less hard plastic material and have a width corresponding to the respective requirements.
  • FIG. 2 shows a device according to the invention, which is placed as an intermediate piece 1 on a centering tube 2 of a drilling bell 3.
  • the drill tip 4 protrudes from the centering tube 2 and engages with a laterally protruding cutting edge 5 in the lateral slots 6 of the intermediate piece 1.
  • An enlarged bore 7, into which the centering tube 2 is inserted, and the slots 6 form a first receptacle 8 for the drill 9.
  • a second receptacle 10 is located on the other side of the intermediate piece 1 and forms the connection to a fastening element, as shown in FIG. 2.
  • the receptacle 10 is designed as a groove 11 with an inwardly curved groove base 12. The purpose of this curvature is that the shaft end of the fastening element resting against it is automatically centered.
  • FIG. 1 one is connected to the drill 9 above the drilling bell 3 whose shaft 13 can be seen, which can be inserted into the chuck of a drilling machine.
  • a hose 14 extending laterally from the drilling bell 3 serves to suck off the drilling dust when creating a borehole in a masonry.
  • the intermediate piece 15 shown in FIG. 2 has a bore in the area of its first receptacle 16 with an inner diameter which is adapted to the shaft diameter of the drill 17.
  • the drill 17, like the drill 9 shown in FIG. 1, can also have laterally projecting cutting edges 5 which engage in corresponding slots 18 on the intermediate piece 15.
  • the drill 17 has a partially flattened end face 19 which bears against a corresponding stop 20 of the intermediate piece 15.
  • the second receptacle 21 is formed in this intermediate piece 15 as in the intermediate piece 1 shown in Figure 1.
  • a square 24, which engages in the receptacle 21, is formed on the shaft end of a fastening element 23 protruding from the borehole 22.
  • the end face of the square 24 has a curvature which is adapted to the curvature of the groove base 12 (FIG. 1).
  • the fastening element 23 has an expansion body 25, an expansion element 26 designed as an expansion sleeve, a shaft 27 and an intermediate ring 28 arranged between the shaft 27 and the expansion element 26.
  • the expansion cone 25 is connected to the shaft 27 via a thread 29. As soon as the expansion cone 25 with its end-side anti-rotation device 30 comes into contact with the bottom of the borehole 31, further rotation of the shaft 27 causes the expansion cone 25 to be drawn into the expansion element 26 and this spreads it out. If the maximum spreading effect is reached, the pressure on the intermediate ring 28 increases, which deforms when the pressure is correspondingly high, thereby limiting or damping the increase in torque.
  • FIG. 3 shows the sectional plane of the intermediate piece 15 running through the slots 18.
