    摘要: A spreading anchor (1) including an anchor rod (2) provided at its front end, when viewed in a setting direction, with a head (3, 30) having at least several regions, which taper outwardly in the setting direction, and extending through an axial through-bore of an expansion sleeve(5) axially displaceable along the anchor rod (2, 20) and having a plurality of axial longitudinal slots (7) extending from a front end of the expansion sleeve (2, 20) and forming at least two, located opposite each other expansion tabs (6) provided at their free front ends with cutters (16), the spreading anchor (1) being supported against an upper surface of a ground (G) and further including rotation-transmitting driver elements for transmitting axial rotation, which is generated during setting of the anchor rod (2, 20), to the expansion sleeve (5).
