Abstract:
Device for fixing, tensioning or pulling an extensible traction element (1), comprisingsupports (15, 16) movable toward each other transverse to a longitudinal axis (2) of the traction element (1), a plurality of pairs of clamping jaws (19, 20) arranged mutually opposite on the supports (15, 16) one behind another in a direction of the axis (2) of the traction element (1) whereby two adjacent pairs of said clamping jaws (19,20) are spaced an initial distance from one another, said clamping jaws (19,20) having engagement surfaces for engaging the traction element (1) along a substantial length of said clamping jaws in said direction of said axis (2), and wherein said clamping jaws (19,20) are adapted to tightly grip the traction element (1) to prevent substantial axial movement of the traction element (1) relative to the clamping jaws (19,20), a majority of the clamping jaws (19, 20) being displaceable in the direction of the axis (2) from a basic position on the supports (15, 16) away from a rearmost pair of said clamping jaws (19,20), and wherein in operation under load of the traction element (1) and consequent elongation of the traction element (1), adjacent pairs of said clamping jaws (19,20) move away from one another in the direction of said axis (2) so that a second distance between said two adjacent pairs of said clamping jaws (19,20) after said elongation becomes greater than said initial distance.
