XQV YJM15 Live End Round Anchor – Permanent Anchorage for Post-Tensioning Systems

Complete YJM15 Series Round Anchor – High Anchorage Efficiency for Bridge, Building & Infrastructure Projects

Product Introduction

XQV YJM15 Series Anchor is a key anchorage device used in concrete structures to achieve prestress tensioning. Its core principle is to transfer the tensile force of prestressed steel bars (or steel strands) to the concrete component through mechanical locking, thereby establishing a pre-compressive stress inside the component to improve the crack resistance and bearing capacity of the structure. It is an important component of the prestressed round anchorage system, featuring high anchoring efficiency, wide applicability, strong reliability, etc. The YJM15 Live End Round Anchor is designed for permanent fixation in post-tensioned concrete members, compatible with 15.2mm (0.6″) steel strands and various jack models.

Application

XQV YJM15 Series Live End Round Anchor 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).

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.
