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 that 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, for this purpose the shaft part can be rotated by hand using a screwdriver or the like.
  • the invention has for its object to provide a mounting unit that uses an expansion anchor that can be expanded by rotation on the shaft part and that uses a one-piece mounting tool that can be clamped into a drilling machine.
  • the solution to this problem is obtained in an assembly unit of the type mentioned by the features specified in the main claim.
  • the toothed ring formed on the assembly tool engages on the front side of the shaft part during assembly and takes the shaft part with it when it rotates.
  • the expansion sleeve of the expansion anchor located between the shaft part and the expansion body is pushed onto the expansion body and thereby expanded until there is a positive connection with the masonry. If a further spreading is no longer possible, this has the consequence that the shaft part can no longer be rotated further, so that at this point in time the ring gear of the assembly tool on the end face of the shaft part rotates.
  • the maximum torque that can be transmitted from the assembly tool to the shaft part can be set to a high value or a lower value. If the ring gear is formed by longitudinal ribs located on a conical surface, the height and the steepness of the longitudinal ribs can also be selected such that a desired maximum transmissible torque is obtained.
  • the teeth of which protrude axially it can engage a smooth annular surface of the shaft part.
  • a cone with longitudinal ribs is used on the assembly tool, it is particularly advantageous if a correspondingly conical inner surface is formed on the shaft part, which is provided with longitudinal grooves or longitudinal ribs.
  • the conical wall formed on the shaft part can also be provided without longitudinal ribs, provided that only a relatively low torque has to be transmitted from the assembly tool to the shaft part.
  • the shaft part has an inner cone as a counterpart that widens toward the end face of the shaft part.
  • an inner cone can also be formed on the assembly tool, an outer cone with longitudinal ribs then being formed as a counterpart on the shaft part of the expansion anchor.
  • a reduced-diameter guide pin can be formed on the end face facing the shank part of the expansion anchor, which protrudes into a bore, preferably into a threaded bore of the shank part, and thereby centers the assembly tool on the shank part.
  • the assembly unit shown in Figure 1 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 with its internal thread 6 is screwed onto the threaded bolt 3.
  • the assembly tool 1 has a shaft 9 which can be clamped in an impact drill or the like, not shown here.
  • a guide pin 11 and a recessed ring gear 12 are formed on the end face 10 facing the shaft part 5.
  • the assembly tool 1 is placed on the end face 15 of the shaft part 5 protruding from the borehole 13.
  • the ring gear 12 is pressed against the annular end face 16 and set in rotation by the impact drill in the percussion drilling operation.
  • the shaft part 5 rotates and is screwed onto the threaded bolt 3.
  • the expansion sleeve 7 is thereby pushed onto the expansion body 4, as a result of which the expansion slats spread out in the undercut 17 and produce a positive connection to the masonry 14.
  • the shaft part 5 can no longer be turned, which is why the assembly tool 1 rotates with the ring gear 12 on the annular surface 16.
  • the function is basically the same.
  • an assembly tool 1 is used, on which a ring gear is formed.
  • the ring gear consists of longitudinal ribs 18 which are attached to an outer cone 19.
  • An inner cone 20 adapted to the outer cone 19 is provided on the shaft part 5 and also has longitudinal ribs 21 on its conical wall.
  • FIG. 3 there is an inner cone 22 on the assembly tool 1 provided that cooperates with an outer cone 23 during assembly.
  • longitudinal ribs 18, 21 are provided on the conical surfaces.
  • the outer cone 23 is located at the projecting end of a threaded rod 24 connected to the shaft part 5.
  • the shaft part also has an internal thread 6, as in FIG. 1 and FIG. 2, into which the threaded bolt 3 engages.
  • the shaft part 5 is screwed onto the threaded bolt 3 by rotation, as a result of which the expansion sleeve 7 is pushed onto the expansion body 4 and is thereby expanded.
  • a screw nut 25 is screwed onto the threaded section 24, with which an object to be fastened to a wall can be fastened.
  • a screw engaging in the internal thread 6 of the shaft part 5 can be used as the fastening element.
