XQV YJM15 Live End Round Anchorage – Multi-Strand Circular Anchorage for Post-Tensioning

High-Efficiency Live End Round Anchor for YJM15 Strand – Reliable Load Transfer for Bridge & Building Structures

Product Introduction

XQV YJM15 Series Anchorages have become one of the most widely used types of anchorage devices in bridge and construction engineering due to their characteristics of symmetrical force distribution, high-tonnage anchoring capacity, and ease of construction. Comprising core components such as anchor plates, wedges, and spiral reinforcement, these anchorages ensure structural safety and construction efficiency through standardized design and mature manufacturing processes. In practical applications, the anchorage type and components can be tailored to suit the structural form of post-tensioning, prestressed tendon layout, and load requirements. The YJM15 live end round anchor is designed for on-site tensioning operations, working with hydraulic jacks to apply and maintain prestress, with high anchoring efficiency (ηa ≥ 95%).

Key Features & Advantages

⚖️ Symmetrical Force Distribution: Ensures uniform load transfer across all strands, reducing stress concentration.

🏗️ High-Tonnage Anchoring Capacity: Available for 1 to 31 strands (15.2mm / 0.6″), covering a wide range of bridge and building applications.

🔧 Ease of Construction: Standardized design and mature manufacturing processes simplify on-site installation.

🔗 Live End Tensioning: Designed for on-site post-tensioning operations with hydraulic jacks (YCW series).

📊 High Anchorage Efficiency: ηa ≥ 95% ensures reliable load transfer with minimal stress loss.

🏭 High-Strength Materials: Anchor head made of 40Cr alloy steel; wedges of 20CrMnTi for wear resistance.

🧪 Corrosion Protection: Surface treatment available for extended service life in harsh environments.

📜 Compliant Standards: Manufactured to GB/T14370-2015, JT/T329-2010, TB/T3193, ISO, CE, ASTM, BS.

Application

XQV YJM15 Live End Round Anchorage is widely used for permanent anchorage in post-tensioned concrete structures. Its high anchoring efficiency and reliable locking mechanism make it suitable for the following fields:

Bridge Engineering: Permanently anchors prestressing strands in box girders, T-beams, segmental bridges, and cable-stayed bridge towers. The anchor plate distributes loads effectively, ensuring long-term structural integrity under cyclic traffic loads.

Building & High-Rise Structures: Used in post-tensioned floor slabs, transfer beams, parking garages, and large-span stadium roofs. The round anchor head fits seamlessly into concrete formwork, simplifying construction.

Tunnel Lining & Underground Works: Anchors prestressed rock bolts and concrete linings for highway and railway tunnels. The corrosion-protected bearing plate resists groundwater and aggressive soil conditions.

Dam & Hydropower Projects: Applied in concrete gravity dams, arch dams, lock chambers, and hydraulic tunnel penstocks. The anchor system withstands high water pressure and provides permanent pre-compression.

Slope Stabilization & Ground Anchors: Provides permanent ground anchor fixation for retaining walls, landslide remediation, and deep excavation support. Compatible with various strand configurations (YJM15 series, 1-31 strands).

Precast Concrete Industry: Used in precast beam, slab, and pile production lines. The live end anchor allows precise prestress transfer from jack to concrete member, improving product quality and consistency.

Railway Engineering: Applied in prestressed concrete sleeper production and rail anchoring systems requiring high fatigue resistance.
