Product Specification
| High Light | P-type anchor for steel strands ，Fixed-end grip anchorage system ，Prestressed strand wedge anchor | ||
As a critical fixed-end component in post-tensioning prestressed concrete structures, the Fixed-end Grip Anchorage (P-type Anchor) for Prestressed Steel Strands is widely applied in bridges, high-rise buildings, and precast components. Compliant with GB/T 14370-2015 and ISO standards, it offers reliable prestress transmission, easy installation, and long-term durability—making it a top choice for construction projects requiring stable fixed-end anchoring.
What is a P-type Fixed-end Grip Anchorage?
The P-type anchor is a one-piece fixed-end anchorage for single prestressed steel strands (common diameters: 15.2mm, 12.7mm). Its structure includes:
Spring cage: Wraps the steel strand to enhance grip force;
Grip wedge: Clamps the strand tightly to prevent retraction;
Sealing cap: Protects the end from corrosion;
Base plate: Fixes the anchor to concrete and disperses stress.
It works by "gripping" the steel strand via the spring cage and wedge, transmitting prestress directly to the concrete structure without additional tensioning at the fixed end—simplifying construction processes.
Core Advantages of P-type Fixed-end Anchorage
High Anchoring Reliability
Made of high-strength alloy steel, the wedge and spring cage ensure an anchoring efficiency ≥95% (meets GB/T 14370 requirements), resisting long-term prestress loss.
Easy Installation
No on-site tensioning is needed; just insert the steel strand into the anchor and embed it in concrete—reducing construction time by 30% compared to traditional anchors.
Corrosion Resistance
The sealing cap and anti-rust coating (optional hot-dip galvanizing) protect the anchor from moisture and chemical erosion, suitable for humid or coastal engineering environments.
Wide Compatibility
Fits 12.7mm, 15.2mm, 15.7mm prestressed steel strands, matching YMP series models (e.g., YMP15-1 for 15.2mm strands) for diverse project needs.
Typical Applications
Bridge Engineering: Fixed ends of box girders, T-beams, and bridge decks;
Building Construction: Prestressed floors, shear walls, and precast components;
Special Projects: Hydraulic dams, slope reinforcement, and underground structures.
