ABSTRACT:
An anchor rod has an axially extending anchoring region including an axially extending expansion section widening in the direction the rod is inserted into a borehole in a structural component. The anchor rod is held in the borehole by a hardenable mortar compound. The mortar compound is prevented from adhering to the anchoring region. Since the mortar compound does not bond to the anchor rod, if there is relative movement between the anchor rod and the hardened mortar compound, the expansion section develops compressive force deviating from the rod axis and acting on the mortar compound, while the compound maintains composite action with the structural component, particularly in a fractured tension zone of the structural component.
