Abstract
An anchorage device for a tension wire bundle of tension wires made of composite fibre materials, which are arranged in a plurality of layers. The tension wire layers are clamped between clamping plates non-slidable in the traction direction. The tension wire layer is clamped between two wedges slidable in the longitudinal direction. With this arrangement, the longitudinally slidable tension wire layer is clamped so that the tractive force acting in it is transmitted practically over its total circumference through the clamping elements to the wedges.

An anchorage device for a tension wire bundle of tension wires which are arranged in a plurality of tension wire layers between clamping surfaces, said anchorage device including:
- a rectangular frame defining an aperture;
- a plurality of non-slidable clamping plates arranged within the aperture;
- first clamping surfaces arranged between respective clamping plates and the frame for clamping n-1 of the tension wire layers;
- a pair of slidable clamping wedges arranged within the aperture centrally with respect to the clamping plates;
- second clamping surfaces between the clamping wedges for clamping the other tension wire layers;
- and sliding surfaces located on the clamping wedges and adjacent clamping plates.
