Product Name: Post Tension Slab Prestressed Wedge for Multi Strand Model NO.: ZT Type: Fasteners Material: metal Technics: Casting Surface Treatment: Yes Certification: CE, ISO Application: Building Slabs PC Strand: 1-15holes Anchorage Shape: Round or Flat Dimension: for 12.7mm, 12.9mm, 15.1mm, 15.9mm. PC Strand Wedge Form: 2 Chip or 3 Chips Trademark: zt Transport Package: Wooden Box Specification: steel Origin: China Product Description Description of post tension anchor system:wedge anchor plate is designed and manufactured under quality control program to meet international standards.wedge anchor plateconsists of stress-end anchorage, fixed-end (dead-end )anchorage, plastic or metal corrugated duct, coupler and PC strand.wedge anchor platemating strands with various diameters: LQM13 for strand diameter 12.5/12.7/12.9mm, LQM15 for strand diameter 15.24/15.3/15.7mm, LQM18 for strand diameter 17.8mm, LQM22 for strand diameter 21.8mmApplication of wedge anchor plate1. wedgeanchor platecan be used efficiently in all applications of Building and Civil Engineering works includingBuilding floor slabsBridge girdersTanks and Silosmany other applications2.wedgeanchor plate iscommonly 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 tendons consist of a bundle of strand with a nominal diameter of 0.5" (12.7 mm.) or 0.6" (15.2 mm.).3. The strands are individually gripped in one anchor head 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.
