Product Specification
Prestressing anchors and wedges are core matching components for post-tensioned prestressed concrete projects. Composed of anchors (multi-hole metal components) and wedges (self-locking wedge parts), they apply stable prestress to structures like bridges, box girders, and high-rise buildings through the process of "tensioning steel strands → wedges locking tightly → anchors transferring loads". This significantly enhances the crack resistance, load-bearing capacity, and span limits of components.
Core Advantages
-
Stable Anchoring & Reliable Safety
Wedges feature precision tooth profiles that form a "bite-type self-lock" with steel strands, achieving an anchorage efficiency coefficient ≥95% with no risk of slippage during long-term use. Anchors are forged from alloy structural steel, with fatigue strength of over 1.8 million cycles, suitable for heavy-load and long-span projects.
-
Multi-Type Compatibility & Wide Applications
- By shape: Round anchors (for long-span bridges) and flat anchors (for thin-walled floor slabs/box girders);
- By hole count: 2–27 holes (and other specifications) to match construction needs for different numbers of steel strands.
-
Weather Resistance & Adaptability to Harsh Conditions
Surface-treated with hot-dip galvanizing/phosphatization, it offers ≥500 hours of salt spray corrosion resistance, suitable for harsh environments like coastal or high-humidity areas. Operating temperature ranges from -40℃ to +60℃, adapting to projects in diverse climate zones.
-
Efficient Installation & Controllable Costs
Precisely sized to match GB/ASTM standard steel strands, on-site installation requires no additional adjustments. Standardized mass production ensures better cost-effectiveness than similar imported products.
Application Scenarios
- Longitudinal/transverse prestressing construction of highway/railway bridges and large box girders;
- Unbonded prestress reinforcement of floor slabs and shear walls in high-rise buildings;
- Prestressed components in special projects (e.g., wind power foundations, nuclear power plants);
- Assembly anchoring of precast concrete components (e.g., PC wall panels).
The product complies with Anchors, Clamps and Couplers for Prestressing Tendons (GB/T 14370-2015) and ASTM international standards. Custom hole counts/specifications are available, and construction technical guidance is provided.
