Bridge Wearing Prestressed Tendon Tension Anchor

Application for the post tensioning anchor:
1. post tensioning of anchor can be used efficiently in all applications of Building and Civil Engineering works including
A. Building floor slabs B. Bridge girders C. Many other applications
2. post tensioning of anchor is commonly used in bridge construction as well as other civil Engineering structures such as Silo, Water tank etc.
3. The strands are individually gripped in one anchorage unit and transmits their prestressing force by means of anchor plate casting unit type M.
4. 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.
5. 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.
6.To ensure corrosion protection and to give adequate bond strength, the tendons are filled with suitable cement grout mix after complete stressing of the strands.
Parameter for post tensioning anchor:According to the diameter of PC strand can be divided into YM12.7, YM13, YM18 type anchorage, the anchoring system is mainly applicable to the strength of 1860MPA-2000Mpa and below the level of 12.7mm, 12.9mm, 15.24mm, 15.7mm, and 17.8mm as the standard strength of steel strand of 5mm-7mm high strength steel beam 1670Mpa. Wide range of options, YM is suitable for design of tension anchor system between 0-12000KN, the number of steel strand range is 55;
post tension anchorIncluding the M series steel wire tension and anchor system: M13 (anchorage for 12.7-12.9mm steel strand and anchorage (M15) used in 15.2-15.7mm steel wire) with YCW series Jack and ZB4-500 type electric pump for tension; for flat structure BM13 and BM15 flat anchorage for cyclic stress; the structure of the HM13 and HM15 ring anchor.
