Mono Strand Wedge Anchorage is a high-performance single-strand
component for post-tensioning systems. It ensures secure clamping
and stable prestress transmission, widely used in bridges,
high-rises, precast parts and slope reinforcement. Compliant with
GB/T 14370, ISO and BS 5896, it performs reliably in diverse
environments.
Core Structure & Working Principle
It consists of four key components for durability and
functionality:
Single-Hole Anchor Plate: Precision-machined for 12.7mm/15.2mm/15.7mm strands, ensuring
tight fit and uniform load distribution.
Self-Locking Wedge Clips: Heat-treated 40Cr steel (HRC 50-65) grips strands tightly,
preventing retraction.
Anchor Bearing Plate: Disperses prestress to avoid concrete cracking and enhance
structural integrity.
Protective Cap: Shields from corrosion and debris, extending service life in
harsh environments.
During construction, insert the strand through the anchor plate and
wedges. Tensioning draws wedges into the plate for irreversible
grip, locking prestress and transferring it evenly to concrete
without extra devices.
Key Advantages
1. Reliable Anchoring
Self-locking design achieves ≥95% anchoring efficiency, resisting
prestress loss and slippage for structural safety.
2. Easy Installation
Compatible with standard jacks, no specialized tools needed. Cuts
construction time by up to 30%.
3. Durable & Corrosion-Resistant
Heat-treated components with optional anti-corrosive coating,
suitable for coastal and underground projects.
4. Wide Compatibility
Fits 12.7mm/15.2mm/15.7mm strands, customizable for various project
needs.
Typical Applications
Widely used in:
Bridges: Box girders, T-beams, bridge decks;
Buildings: Prestressed floors, shear walls, precast parts;
Special Projects: Slope stabilization, dams, underground
structures.
