Multiplane Anchorage MA

Bonded Strand Post-Tensioning System - Anchorage Types - Multiplane Anchorage MA The two-part multiplane anchorage is primarily used for longitudinal tendons in beams and bridges. The wedge plate and the conical anchor body with usually three load transfer planes introduces the prestressing force continuously into the member with minimal front area. The separation of anchor body and wedge plate makes it possible to insert the strand after casting the concrete. The wedge plate self-centers on the anchor body, providing consistent assembly and installation as well as trouble-free stressing.

Plate Anchorage SD

Bonded Strand Post-Tensioning System - Anchorage Types - Plate Anchorage SD The single unit plate anchorage is designed for plate structures as well as transverse tendons in bridges. Small edge and center distances allow for an economical anchorage layout in condensed situations.

Bond Head Anchorage ZF/ZR

Bonded Strand Post-Tensioning System - Anchorage Types - Bond Head Anchorage ZF/ZR Primarily used with prefabricated tendons, it is also possible to fabricate this anchorage on site. The strand wires are plastically deformed to ensure a safe load transfer up to ultimate capacity in the area of the bond head proven in static as well as in dynamic applications. Depending on the boundary conditions, either a rather flat or a bulky bond head anchorage pattern is available.

Loop Anchorage HV

Bonded Strand Post-Tensioning System - Anchorage Types - Loop Anchorage HVOften used in large plate-shaped structures, walls in off-shore structures or LNG tanks with generally static loadings. The 180° loop should be positioned in the center of the tendon to allow for non-slippage during simultaneous two-end stressing.

Flat Anchorage FA

Bonded Strand Post-Tensioning System - Anchorage Types - Flat Anchorage FA The Flat Anchorage of max. 4-0.62" strands in one plane to deviate into one oval duct is designed to be installed in thin members such as transverse Post-Tensioning of the top slab of box-girder bridges and prestressed flat slabs.
