Round Anchor Head is a core anchoring component for post-tensioning prestressed concrete systems, featuring a compact circular structure. It is specially engineered to secure prestressed steel strands (12.7mm, 15.2mm, 15.7mm) and transmit tension stably to concrete structures, widely applied in bridges, precast components, and high-rise building construction. Compliant with GB/T 14370, ISO, and ASTM standards, it delivers reliable performance in diverse engineering scenarios.
Core Features & Structure
Adopting an integrated circular design, the anchor head consists of three key parts for optimized functionality:
- Circular Anchor Plate: Precision-machined with multi-hole distribution, ensuring uniform stress dispersion and tight fit with steel strands.
- High-Strength Wedges: Heat-treated alloy steel (HRC 50-65) for firm clamping, preventing strand retraction and ensuring anchoring efficiency ≥95%.
- Protective Cover: Seals the anchor head to resist moisture and debris, extending service life in harsh or outdoor environments.
Its symmetrical round structure enables flexible installation without strict orientation requirements, simplifying on-site operation and reducing construction errors.
Key Advantages
- Stable Stress Transmission: Circular design disperses concentrated tension evenly, avoiding local concrete cracking and enhancing structural integrity.
- Easy Installation: Symmetrical structure allows quick positioning, compatible with standard tensioning jacks for efficient on-site construction.
- Durable Performance: Available in stainless steel or hot-dip galvanized finish, it offers excellent corrosion resistance for coastal, underground, and open-air projects.
- Wide Compatibility: Customizable hole counts and sizes to fit single or multi-strand systems, adapting to bridge girders, precast slabs, and slope reinforcement.
Typical Applications
- Bridge Engineering: Box girders, T-beams, and bridge deck tensioning ends;
- Precast Construction: Prestressed wall panels, floor slabs, and precast components;
- Special Projects: Hydraulic dams, underground retaining structures, and high-rise building cores.
