Abstract
The invention relates to an expansible anchor () for anchoring in a cylindrical drilled hole (). The invention proposes constructing the expansible anchor () with a tubular basic anchor part (), on which a hollow conical expansion portion () is formed by means of a forming procedure, on which expansion portion () an expansion sleeve () bent out of sheet metal is mounted. As a result of axial displacement of the expansion sleeve () on the expansion portion (), the expansible anchor () becomes anchored in the drilled hole (). The expansible anchor () exhibits subsequent expansion behaviour in the event of widening of the drilled hole (), for example as a consequence of crack formation.
