Furthermore, Stressing anchorage is the most common form of post-tensioning system. It is widely used in concrete structure and soil / rock retaining walls. post tensioning anchorages consist of wedge, anchor head, bearing plate and spiral reinforcement.Multistrand Post-Tensioning SystemThe 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. pocket former for each anchorage system on request

The complete assembly of the steel strand, grease, sheathing, and anchorages is referred to as a post-tensioned tendon. Each steel strand typically has its own sheathing and is referred to as a mono-strand.
Jan 06, 2006 · A post-tensioned system will move 20% to 30% more than conventionally reinforced concrete. A good rule of thumb is that a post-tensioned system will move about 1 inch for every 100 feet of slab that is not restrained by a lateral system. If the edge of the slab is 50 feet away from the nearest shear wall, when post tensioned this edge will move post tensioned concrete mono anchor plateMK4 Post Tensioning System - Halfen Moment GroupThese Dead End anchorages MPT comprise trumpet, anchor plate, extrusion grips and retention plate. Live End Anchorage MUNB 1/0.6 The MK4 unbonded mono-strand system uses 15 mm (0.6) diameter strand and a live end anchorage MUNB 1/0.6 which can also be used as a passive anchorage by incorporating a seal cap and a spring.Moment® Flat Slab System - Halfen Moment GroupThe strands are individually gripped in one triangle flat anchor head unit and transmit their pre-stressing forces by means of flat type anchor plate casting unit. The strands are stressed individually by means of a mono strand jack. The strands are contained in one flat duct (duct size: 20mm x 70mm) which is made of corrugated galvanized metal.
Monostrand Post-Tensioning System The strength, serviceability and design flexibility of concrete are greatly enhanced by the DYWIDAG Monostrand Post-Tensioning System. DYWIDAG Monostrands are made up of cold-drawn, low-relaxation, seven wire strands of 0.5" (12.7 mm) or 0.6" (15.2 mm) diameter, conforming to ASTM A 416.Multistrand Post-Tensioning SystemThe 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.Post Tensioning & Bridge Applications - Halfen Moment GroupIn post-tensioning the prestressing force is applied directly to the concrete. In the case of pre-tensioning the anchor holds the strands until after the concrete has gained sufficient strength; the strands are then released, transferring the prestressing force to the concrete.
