ABSTRACT:
A rod-shaped tension member formed of fiber reinforced composite material is utilized as an anchoring rod in foundation and mining construction, or as a reinforcing member in concrete and prestressed concrete construction. At least, in an axially extending region where it is to receive an anchoring member, such as a rod, the tension member has a continuous helical thread formed of alternating ribs and recesses. The anchoring member has a corresponding thread so that it can be screwed onto the tension member thread. An intermediate layer is provided between the threaded regions of the tension member and the anchoring nut, and is formed of a material affording large plastic deformation relative to the tension member when slight stress increases occur at overload conditions. Accordingly, between the threads on the tension member, and the nut, the plastically deformable intermediate layer has a strength less than that of the fiber reinforced composite material whereby it is subject to compression, acting transversely of the rod. As a result, stress peaks in the tension member are avoided by the plastic deformation of the intermediate layer.
