Abstract

An anchoring means for anchoring a rock bolt made of concrete steel in a drill hole. The anchoring means comprises a body portion (1) intended to surround the concrete steel (6) and having a longitudinal slit (1a) at one side. The body portion (1) further comprises fixing tabs (4, 5) on the inside and gripping tabs (2, 3) on the outside for gripping the inner surface of the hole. The concrete steel (6) is inserted through the slit (1a) inside the body portion (1) so that the fixing tabs (4, 5) are positioned between the gripping protuberances (6a) of the concrete steel (6) and lock the anchoring means immovably in the longitudinal direction of the steel (6).
