Method of anchoring fastening element |
摘要 |
A method of anchoring a fastening element includes drilling a borehole (7) in a constructional component (6) with a percussively-rotationally driven hollow drill (12), while aspirating produced drillings and drilling dust with a vacuum source (26) through a gap between an outer side of the hollow drill (12) and a wall of the borehole (7) during drilling of the borehole (7), immediately after formation of the suction-cleaned borehole (7), filling the borehole (7) with a self-hardenable mortar (41), and inserting the fastening element (46) into the self-hardenable mortar (41).
