Product Description
The Round Anchor Head serves as a core anchoring component for post-tensioning prestressed concrete systems, featuring a compact circular structure. Engineered specifically to secure prestressed steel strands (12.7mm, 15.2mm, 15.7mm), it efficiently transmits tension to concrete structures. Widely utilized in bridges, precast components, and high-rise building construction, this component complies with GB/T 14370, ISO, and ASTM standards, ensuring reliable performance across diverse engineering applications.
Core Features & Structure
Utilizing an integrated circular design, the anchor head comprises three essential components for optimal functionality:
- Circular Anchor Plate: Precision-machined with multi-hole distribution to ensure uniform stress dispersion and secure fit with steel strands
- High-Strength Wedges: Manufactured from heat-treated alloy steel (HRC 50-65) for firm clamping, preventing strand retraction and achieving anchoring efficiency ≥95%
- Protective Cover: Seals the anchor head against moisture and debris, extending service life in harsh or outdoor environments
The symmetrical round structure enables flexible installation without strict orientation requirements, simplifying on-site operations and minimizing construction errors.
Key Advantages
- Stable Stress Transmission: Circular design disperses concentrated tension evenly, preventing local concrete cracking and enhancing structural integrity
- Easy Installation: Symmetrical structure allows quick positioning and compatibility with standard tensioning jacks for efficient on-site construction
- Durable Performance: Available in stainless steel or hot-dip galvanized finish, offering 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
Standards Compliance: Meets GB/T 14370, ISO, and ASTM standards for quality assurance and engineering reliability.
