Abstract:
An anchor rod to be received in a bore filled with mortar mass, comprising a connection region (22), and an anchoring region (23) having a free end and a plurality of axially arranged one after another, conical enlargements (24) a diameter of which increases in a direction toward the free end,wherein the conical enlargements are provided with circumferential sections (25) radially spaced from a longitudinal axis of the anchor rod (21) by a greatest distance, having a radius (r) smaller by from about 0.1 mm to about 1.5 mm than a half of a nominal diameter of the anchoring region receiving bore, and extending, respectively, in a circumferential direction over an angle of up to 300.degree.,wherein the conical enlargements (24) are provided with flattenings (27), andwherein a circumferential section (25), which is radially spaced from the longitudinal axis (A) of the anchor rod (21) by a greatest distance and has a flattening (27), is spaced from the longitudinal axis (A) at the flattening (27) by a minimal radial distance (s) which amounts to from 30% to 90% of the radial distance (r) of a non-flattened circumferential section (25) from the longitudinal axis (A).
