摘要

The expansion anchor comprises an expansion sleeve (2) which is supported on a stump cone (3) of a head bolt (1) with expansion tabs (6). The front face of the expansion sleeve is attached at a plane surface (9) of a head (5) and is adjusted axially. The outer diameter of the head is greater as compared to the borehole such that the head holds a part which is to be mounted. The expansion sleeve at its larger diameter is greater as compared to the diameter of the bore hole.
