Site installation

Fork to fork tendon

For rapid installation on site DST460 tendons are pre-assembled in the factory and set to their nominal pin-pin length. The tendons are then ready for immediate incorporation into the structure and generally require no site assembly, saving valuable time. To install follow the steps below.

  1. Back off lock covers
  2. Install tie rods and pins
  3. Adjust to length-torque to required value if required
  4. Tighten lock covers

Fork to fork tendon with turnbuckle

Tendons longer than 12m will be split into transportable lengths and some site assembly will be required. Ensure all components are fitted to the bar and the nominal pin-to-pin length has been set. Follow the steps below:

  1. Back off turnbuckle locking thread covers
  2. Install tie rods and pins, tighten fork lock covers
  3. Adjust tendon length with turnbuckle-torque to required value if necessary
  4. Tighten turnbuckle lock covers

For extra security the pin end caps can be secured using a chemical locking compound (such as 'Loctite') on the counter sunk set screws.

Forks are generally drilled with a blind hole to prevent any run-off from the bars. The lock cover/bar opening can be sealed with a proprietary exterior silicon sealant if required.
