Device for introducing a force into tension members made of fiber-reinforced plastic flat strip lamellas

A method for introduction of force into tension members made of fiber-reinforced plastic flat strip lamellas, using a device having a rigid sleeve for arrangement around two clamping elements and configured for exerting a clamping pressure on the tension member via the clamping elements;

• wherein the clamping elements each form a semi-cylindrical structure that together form a cylindrical outer surface, and the sleeve has an inner shape configured to receive the cylindrical outer surface of the two clamping elements and configured for exerting a clamping pressure;
• and
• wherein the at least one clamping element and the at least one rigid sleeve each include respective chamfered edges, the method comprising:
• placing a tension member on at least one clamping element made of plastic having a modulus of elasticity ranging from 1000 to 5000 MPa, a bending tensile strength of >25 MPa and a pressure resistance of >25 MPa so that the clamping element has at least one contact surface with the tension member;
