XQV YJM15 Dead End PT Anchorage – Fixed End Anchorage for Post‑Tensioning Systems
High‑Strength Cast Steel Anchor for Reliable Force Transfer & Structural Integrity
The XQV YJM15 dead end PT anchorage system is a key component in prestressed concrete structures, used for permanently fixing prestressing tendons. It is composed of components such as fixed‑end anchor head, top plate, extrusion sleeve, bearing plate, and spiral reinforcement. Through mechanical locking and/or bonding action, it transfers the tensile force of the prestressing tendons to the concrete member, ensuring effective establishment and long‑term maintenance of prestress. The system fully complies with GB/T14370‑2015, JT/T329‑2010, TB/T3193, ISO, CE, ASTM, BS and other international standards.
🔧 High Anchorage Efficiency
ηa ≥ 95%, ensuring reliable prestress transfer and structural integrity.
🛡️ Robust Construction
Cast steel anchor head and high‑strength bearing plate withstand extreme tension loads.
🔄 Extruded Grip Option
Extrusion sleeve provides mechanical locking without requiring additional wedges for dead ends.
📐 Wide Compatibility
Suitable for φ15.2 mm (0.6″) low‑relaxation steel strands, the most common prestressing tendon size.
🏗️ Easy Installation
Pre‑assembled components simplify on‑site placement; spiral reinforcement ensures concrete anchoring.
