Abstract

An anchor rod is secured within a bore hole by a hardenable adhesive compound. To hold the anchor rod within the bore hole before the adhesive compound sets, clamping members are provided on the exterior surface of the rod inserted into the borehole. The clamping members include rolling bodies held on a clamping surface on the rod so that a tendency of the rod to be displaced from the bore hole effects a wedging action by the clamping surface forcing the rolling body against the surface of the bore hole. The rolling bodies or balls can be held on the clamping surface by an elastomeric sheathing or springs.
