Chapter The external lightning protection system
.g. through sticking with special mortar.2.2 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. Examples are back cut internal thread an-
chors cavity ceiling ties.
When frictional connection made, spreading ele-
ment set the anchor body ensures locking the
drill hole. The anchor fits "tightly" into the com-
ponent. Cleaning the drill holes very important for
these systems, order prevent slipping out due to
dust the drill hole. When mounted with the planned torque, the
friction ensures the high load values. The threads the bolt ties
also work according this principle. Ad-
hesive cartridges injection systems, which a
threaded rod mounted, are included these fasten-
ings.
Firmly bonded anchors join chemically the sub-
strate, e
