Reinforcing element for concrete constructions

摘要

The reinforcement for concrete has shaped as a headed bolt with a stepped tapered cross section. The bolt has a widened section (2a) made of glass fibre reinforced plastic and has a central axial bore which form locks with the outer surface of the bolt shank (3). The form locking action can be provided by profiling (4,5) which acts against axial loads. The profiling can be formed as a screw thread.
