Tie Bar Arrangements:-
Fork - fork
The simplest form of tendon. A bar with threaded forks at each end. Once installed, the tendon can be adjusted in length by rotating the bar.
Fork - Turnbuckle - Fork
Generally for longer length tendons, or where greater length adjustment is required.
A standard turnbuckle gives +/- 50mm adjustment for M20 and above.
Turnbuckles can be supplied with a welded connection cleat to take a hanger or stay bars.
Couplers can be added to a system to increase the length without adding adjustment, and cross couplers are also available for cross bracing without a central disk.
If stressing is required on-site this must be stated on your enquiry. Tendons must be supplied with Jacking Turnbuckles to facilitate the use of a Jacking Rig to stress tendons on site.
A shaped central connection, usually circular, to take an arrangement of fork to fork tendons.
