Principles of function
There are various bearing mechanisms, which the forces, having an effect on the
fixing, initiate in the component.
For friction locking, the expansion part of the anchor is pressed on the drill hole
wall: the outer tensile loads are held through friction.
Through anchor
Plastic fixings
With form locking, the fixing geometry matches the shape of the substrate and/or of
the drill hole.
Undercut anchor Injection fixing 1
With adhesive bond, a mortar binds the fixing with the anchor base.
Injection fixing 2
Rebar
▸ Expert tip
▪ For many anchors, the anchoring takes place through a combination of the active
principles (e.g. friction locking and form lock in soft stone).
