Abstract (en)

[origin: GB2325503A] The device (1) comprises a first coupling (10) adapted for attachment to the tendon (2) adjacent an end (7) thereof, a second coupling (11) adapted for attachment to an anchorage (3), e.g another tendon, separate from said end (7), tie means (15,16) extending between and connected to the couplings (10,11), and load applying means (19,20) operable to act between the tie means (15,16) and at least one of the couplings (10,11) to cause relative movement of the tie means (15,16) and coupling longitudinally of the tendon (2) such as to urge coupling (10) towards coupling (11) and thereby urge said end of the tendon (2) towards the anchorage (3) whereby the tendon (2) is tensioned. Tension can be maintained by a turnbuckle (4). The load applying means are hydraulic piston assemblies (20,21). The couplings (10,11) can be removed laterally. In an alternative assembly the tendon and anchorage are only connected by the couplings in the form of a housing; hydraulic load applying means are associated with both couplings.
