Cleaning the drill holes very important for these systems, order prevent slipping out due to dust the drill hole. The threads the bolt ties also work according this principle. The anchor fits "tightly" into the com- ponent. When frictional connection made, spreading ele- ment set the anchor body ensures locking the drill hole. Firmly bonded anchors join chemically the sub- strate, e. Examples are back cut internal thread an- chors cavity ceiling ties.TBS Blitzschutz-Leitfaden 2018 / en / 2020/01/10 14:42:40 14:42:40 (LLExport_02613) / 2020/01/10 14:42:54 14:42:54 2.2. through sticking with special mortar.2 Fastening principles There are three types force transmission from the anchor the substrate: • Form fit • Adhesive bond • Friction bond Anchors with form-fitting tap the substrate and support themselves it.
