Claims10
A fastening arrangement, comprising:
- a fastening element;
- and
- an anchoring sleeve, wherein the fastening element is disposed in the anchoring sleeve and wherein the fastening element and the anchoring sleeve are anchored in a bore hole by a compound;
- wherein the anchoring sleeve has a sleeve-like base body with a first end and a second end opposite from the first end and a plurality of axially successive extension sections arranged between the first end and the second end, wherein the plurality of extension sections are cone-like, and wherein a diameter of each of the plurality of extension sections increases in a direction of the first end;
- wherein the anchoring sleeve forms conical surfaces in the compound and simultaneously forms a separating plane or glide plane between inner cones formed within the anchoring sleeve by the compound and outer cones formed outside the anchoring sleeve by the compound, wherein the separating or glide plane allows gliding of the inner and outer cones for a spreading behavior of the fastening arrangement when the fastening arrangement is under a load.
