Prestressed Anchorages: Wedges, Anchor Head, Bearing Plate
Flat Anchor:
The Flat Anchor accommodates a maximum of five strands in a single plane, allowing them to deviate into one oval duct. This design is primarily intended for use in thin structural members.
It is commonly employed in the transverse post-tensioning of the top slab in box-girder bridges and prestressed flat slabs.
The system connects strands that run through steel or flat corrugated galvanized steel ducts, which are manufactured in our facility.
Each strand is individually stressed using a mono-strand jack.
To ensure corrosion protection and provide adequate bond strength, the tendons are filled with an appropriate cement grout mix after all strands have been stressed.
Multi Strand Round Anchor:
Round system used mainly in bridges’ beams.
Systems are typically utilized for bonded tendons, with each tendon consisting of a bundle of strands.
The number of strands in a tendon can range from 4 to 42, with varying diameters.
These strands are housed within a single round duct.
The duct is made from locally manufactured corrugated galvanized metal.
Each strand is individually gripped in an anchor head unit and transfers its pre-stressing force through an anchor plate casting unit.
Additionally, the strands in the tendon are stressed simultaneously using a multi-strand stressing jack.
