Abstract
The invention relates to a composite anchor, which consists of an anchor rod (1) anchorable by means of a compound mass in a hole (12) drilled in a building component (13), the anchor rod comprising several cone-like segments (3a, 3b, 3c) widening towards the insertion end (4) and spaced from one another by cylindrical portions (6a, 6b). The length of the cylindrical portions (6a, 6b) is 0.5 times to 2.0 times the length of the cone-like segment (3a, 3b) adjoining the respective portion in the direction of the insertion end (4). This produces a stable mortar shell (14) after the compound mass has hardened, which causes high withdrawal values as a consequence of the cone-like segments (3a, 3b, 3c) settling into the hardened mortar shell (14) following widening of the drilled hole as a result of cracks forming. The composite anchor is therefore especially suitable for anchoring in zones subject to tensile forces.
