Abstract

A ground anchor or rock anchor is provided that includes an anchor tension member composed of one or more individual elements, such as steel bars, steel wires, or steel wire strands. While the anchor tension member is intended to be introduced into a drilled hole and anchored there, the anchoring of the anchor tension member at the exposed end of the drilled hole is achieved with the aid of anchor head. To this end, the anchor head comprises a support element to bear directly or indirectly against the underlying rock or substratum, and an anchoring component for tensioning the individual elements, which can be brought into a frictional connection with the individual elements while bearing against the support element. In addition, a cap, which extends around the anchoring component and the ends of the individual elements, protects the exposed end of the anchor head. For secure attachment of the cap to the rest of the anchor head, between the support element and anchoring component, a connecting element is arranged that has a first closure component at its circumferential side, and has a second closure component of complementary shape on its circumferential side, wherein the first and second closure component work together to produce a frictional connection between the cap and connecting element.
