Abstract

For stressing the second end of a tendon (1) whose first end is already anchored on a first bearing surface of a rigid structure (5), with a view to anchoring this second end on a second bearing surface (3) of the said structure after stressing of the said tendon, use is made of a device comprising a longitudinal stressing jack (V1) whose stationary element (9) is capable of bearing on the second bearing surface (3), a first temporary clamping jaw (30) of the above second end, which jaw is integral with the axially movable element (10, 11) of the jack, and a second temporary clamping jaw (20) of the abovementioned second end, which jaw is integral with the fixed element (9) of the jack. The two jaws work in succession in order to grip the tendon to be stressed during the to-and-fro action of the stressing jack and the clamping pressure of their jaws (32, 22) is applied to the tendon in exclusively transverse directions.
