A core component for post-tensioning systems, the 5-Strand Wedge
Flat Anchorage is tailored for thin concrete structures. It anchors
5 steel strands via wedge clamping, ensuring efficient prestress
transmission with compact design, reliability and wide
adaptability.
I. Structure & Working Principle
The system includes a flat anchor plate (5 parallel holes), wedge
clips, bearing plate and spiral reinforcement (optional corrugated
pipes). It fits 12.5-15.7mm steel strands, neatly placed in flat
ducts.
Strands are tensioned individually; wedge clips grip strands
tightly for self-anchoring. Prestress is evenly transferred to
concrete, with spiral reinforcement preventing cracking. Anchoring
efficiency ≥0.95, meeting standards.
II. Key Advantages
1. Compact & Space-Saving
Flat design reduces space, ideal for height-restricted projects
(bridge decks, basement roofs) with uniform stress distribution.
2. Reliable Anchoring
40Cr anchor plate (HRC 50-60) and high-hardness clips (HRC 50-65)
resist retraction, supporting complex tensioning processes.
3. Easy Installation
Compatible with conventional equipment, it allows flexible
tensioning. Grouting holes prevent corrosion, boosting efficiency.
4. Wide Adaptability
Compliant with global standards, it suits bridges, buildings and
dams. Precision treatment controls friction loss ≤6%.
III. Applications
- Bridges: Transverse prestressing, box girders, hollow slabs;
- Buildings: Prestressed floors, underpasses, basements;
- Special Projects: Dam panels, ports, slope anchoring.
