XQV YJM15 Dead End H-Type Anchor – Fixed-End Anchorage for Post-Tensioning Systems

Pear-Shaped & Scattered-Flower Self-Anchor Head – Reliable Passive Anchorage for Bridge & Infrastructure

Product Introduction

When it needs to apply post-tension to concrete, the YJM15 Series D/R/H type anchorage system can be used. It is composed of PC strand of pear-shaped and scattered-flower-shaped self-anchor head, steel bar bracket, spiral reinforcement, limit ring and corrugated duct. The pear-shaped and scattered-flower-shaped self-anchor head (onion head) is made via pressing by the special YH3 type embossing machine, and the supporting oil pump is the ZB4-500 electric oil pump. The YJM15H dead end anchor is designed for permanent fixed-end anchoring in post-tensioned concrete members, providing reliable load transfer with minimal stress loss.

Application

The XQV YJM15 Dead End H-Type Anchor is specifically designed for fixed-end anchoring in post-tensioned concrete structures. It is widely used in the following fields:

Bridge Engineering: Used as permanent dead-end anchorage for box girder longitudinal tendons, segmental bridge post-tensioning, and cable-stayed bridge tower anchor zones. The pear-shaped self-anchor head ensures reliable strand fixation.

Building Structures: Applied in post-tensioned flat slabs, transfer beams, and foundation mats of high-rise buildings. The H-type anchor provides secure dead-end termination in confined spaces.

Tunnel Lining & Underground Works: Anchors post-tensioned rock bolts and concrete linings for highway and railway tunnels. The complete system (bracket, vent, limit ring, spiral reinforcement) ensures long-term stability.

Precast Concrete Industry: Used for precast beam, slab, and pile production. The fixed-end anchor allows efficient prestress transfer from strand to concrete member.

Water Conservancy & Hydropower Projects: Anchors prestressing tendons in dam foundations, spillway piers, and lock chambers. The corrosion-protected components ensure durability in wet environments.

Slope Stabilization & Ground Anchors: Provides permanent dead-end anchorage for ground anchors in landslide remediation, retaining walls, and deep excavation support.

Railway Engineering: Used for prestressed concrete sleeper (tie) production and rail anchoring systems requiring fixed-end strand termination.
