Stressing slab post tensioning Flat Anchorage for 5 Strands Wedge

The system comprises a flat anchor plate with 5 parallel holes, wedge clips, bearing plate, and optional spiral reinforcement with corrugated pipes. Designed for 12.5-15.7mm steel strands, it accommodates strands neatly arranged in flat ducts.

Individual strand tensioning allows wedge clips to securely grip strands, enabling self-anchoring functionality. Prestress is evenly distributed to the concrete, while spiral reinforcement prevents cracking. The system achieves anchoring efficiency ≥0.95, meeting international standards.

• Compact & Space-Saving: Flat design minimizes space requirements, ideal for height-restricted applications like bridge decks and basement roofs while ensuring uniform stress distribution.
• Reliable Anchoring: Constructed with 40Cr anchor plate (HRC 50-60) and high-hardness clips (HRC 50-65) that resist retraction, supporting complex tensioning processes.
• Easy Installation: Compatible with conventional tensioning equipment, allowing flexible installation procedures. Integrated grouting holes prevent corrosion and enhance operational efficiency.
• Wide Adaptability: Compliant with global standards, suitable for bridges, buildings, and dams. Precision engineering controls friction loss to ≤6%.

• Bridges: Transverse prestressing, box girders, hollow slabs
• Buildings: Prestressed floors, underpasses, basements
• Special Projects: Dam panels, ports, slope anchoring
