Definitions

  • the invention relates to an assembly unit with an expansion anchor and an assembly tool according to the preamble of the main claim.
  • hammering tools which can be clamped in rotary hammers and impact drills are known. These usually consist of hardened steel sleeves, via which the impact of the impact drill is transferred to the dowel sleeve.
  • a disadvantage of the known hammer-in tools is that when the drill is lowered, the hammer-in tool often falls off the drill and must be reattached if the work process is interrupted several times.
  • An expansion anchor, which can be mounted with such an impact tool, is described in DE-A 36 34 431.
  • Expansion anchors which have a rotatable shaft part which, by rotation, pushes an expansion sleeve onto an expansion cone.
  • the shaft part can be turned by hand using a screwdriver or the like.
  • the invention has for its object to provide an assembly unit which uses an expansion anchor which can be expanded by rotation on the shaft part and which has an integral assembly tool which can be clamped into a drilling machine.
  • the corners of the polygon of the assembly tool now act like a milling cutter and rub the inner bore onto a diameter of the corner dimension of the polygon.
  • the torque transmission from the assembly tool to the shaft part is interrupted, so that neither destruction of the expansion anchor nor tearing of the impact drill can occur.
  • the jerk occurring in the inner bore when the torque is interrupted and the polygon is turned can be limited by the features of claim 2 to a level that the fitter can hold with the drilling machine without great difficulty.
  • the assembly tool has a stop shoulder which is seated on the end face when the shaft part is driven in.
  • the assembly unit shown in the drawing consists of an assembly tool 1 and an expansion anchor 2 which has a threaded bolt 3 with an expansion cone 4.
  • the threaded bolt 3 protrudes into a shaft part 5 which is screwed onto the threaded bolt 3 with an internal thread 6.
  • the assembly tool 1 has a shaft 9 which can be clamped in an impact drill or the like, not shown here.
  • the rotary impact effect is supported by the stop shoulder 15 formed on the assembly tool 1, which comes to rest on the end face of the shaft part 5 when the polygon 11 is completely immersed in the inner bore 13.
  • the expanding body 4 seated on the bottom of the borehole 16 bears due to the friction existing between the expanding body 4 and the bottom of the borehole, so that the shaft part 5 can be screwed on axially in the direction of the expanding body 4.
  • the expansion sleeve 7 is pushed from the shaft part 5 onto the expansion body 4 and spreads open, so that the expansion slats 8 engage in the undercut 17 in a form-fitting manner.
  • the shaft part 5 stops abruptly. Due to the torque still applied via the assembly tool 1, the inner bore 13 is rubbed through the corners of the polygon 11 to their corner dimension, so that the assembly tool 1 can continue to rotate without torque transmission.
  • the expansion anchors are protected, on the one hand, and, on the other hand, the impact drill is prevented from being pulled around.
  • An optimal relationship between torque transmission on the one hand and interruption of the transmission on the other hand is achieved if the wrench size of the polygon 11, which is preferably designed as a hexagon, approximately the diameter of the inner bore 13 and the height 14 of the section having the polygon 11 about a third of the wrench size corresponds.
