  • the spreading is traversed by a screw, in which a spreading screw for spreading the spreading is screwed.
  • the known expansion dowel of the expansion section is formed by two mutually perpendicularly intersecting longitudinal slots in axial planes of the expansion anchor, which pass through the expansion of the expansion anchor and divide into four expansion limbs, the apart by screwing the expansion screw in the expansion and outwards, i. be spread.
  • the expansion channel is formed in the known expansion dowel of an intersection of the longitudinal slots, which divide the expansion dowel in the expansion in the expansion leg and thereby form the expansion section.

  • the screw is determined by its function of screwing in the expansion screw.
  • the expansion anchor according to the invention has an internal thread for engagement of a screw thread of an expansion screw.
  • the internal thread is formed in the longitudinal direction of the expansion anchor behind the expansion section, so that the expansion screw can be screwed through the internal thread of the expansion anchor in the screw.
  • the screw can have an internal thread or be thread-free. The internal thread reduces a torque for screwing the expansion screw in the expansible plug, whereby the risk of co-rotation of the expansible plug with the expansion screw when screwed into the expansion dowel reduced.

As a result, a sealing portion is formed, which presses against a borehole wall in the plaster layer during the introduction of the expansion anchor into a borehole in a plaster layer and thus seals there.
  • An embodiment of the invention provides that a perforated disc is arranged on the expansion dowel. This embodiment is provided for attachment to, for example, a plate whose rear side is accessible. When spreading the expansion dowel presses the perforated disc against a back of the plate. The perforated disc enlarges an undercut surface, with which the expansion dowel engages behind the plate, considerably, thereby improving the attachment of the expansion anchor to the plate.
