Product Description
Round prestressing anchors and wedges are essential components for post-tensioned concrete construction, specifically engineered for large-span and heavy-load structures including long-span bridges and high-rise building core tubes.
Product Overview
These precision components consist of a cylindrical anchor body with evenly distributed holes and matching wedges. During tensioning, the wedges securely lock steel strands through self-locking force, effectively transferring prestress to enhance structural load-bearing capacity, crack resistance, and long-term stability.
Core Advantages
- Excellent Load-Bearing: Circular design ensures uniform stress distribution, preventing concentration points. Available in 2-27 hole specifications to accommodate various steel strand quantities, meeting high-load requirements of large-span projects.
- Reliable Self-Locking: Precision serrated wedges tightly grip steel strands during tensioning, achieving anchorage efficiency ≥95% with no long-term slippage, ensuring structural safety and reliability.
- Durable & Corrosion-Resistant: Manufactured from 45# alloy steel with hot-dip galvanizing or phosphatization treatments, providing ≥500 hours salt spray resistance and 1.8 million+ fatigue cycles, suitable for harsh environmental conditions.
- Easy Installation & Compatibility: Compatible with 15.24mm GB/ASTM standard steel strands, requiring no on-site debugging. Works seamlessly with mainstream post-tensioning equipment to enhance construction efficiency.
Application Scenarios
- Long-span highways, railways, cable-stayed bridges and viaducts
- High-rise and super high-rise building core tubes and transfer beams
- Large-span industrial factories, stadiums and convention centers
- Hydropower dam and nuclear power plant heavy-duty prestressed components
Compliant with GB/T 14370-2015 and ASTM standards. Customizable for non-standard hole counts and surface treatments. Contact us for test reports and technical guidance.
