Anchoring (7) comprises a wedge (3) and anchoring body (2) formed by at least two wedge-shaped layers (31, 32) lying over each other. One of the layers (32) is made from a material with a lower elastic modulus than the material of the other layer. Preferred Features: Pores, holes, recesses or slits are arranged in the layer having the lower elastic modulus. The different elastic moduli of the single layers are effected by special treatment such as heating and cooling during their manufacture. The anchoring body has receivers for wedges as coupling for tensile elements. |
