4LQM Post tensionedsystems for multi strand round duct

The post tensioned systems are commonly used in bridge construction as well as other civil Engineering structures such as Silo, Water tank etc.

The systems are normally adopted for bonded tendons.

The strands are individually gripped in one anchor block unit and transmits their prestressing force by means of anchor plate casting unit type M.

For each anchor size a special spiral reinforcement is provided at the anchor plate casting to give adequate splitting reinforcement for burstling stresses developed at the anchorage zone.

The strands in tendon are stressed simultaneously by means of a multi strand stressing jack from capacity 1,100 KN up to 5,000 KN. In case of small size tendon unit such as type M405 the strands can also be stressed individually by means of mono jack.
