XQV YJM15L Multi‑Holes Connector – Product Details

XQV YJM15L Multi‑Holes Connector – Multi‑Strand Coupler for Post‑Tensioning Systems

High‑Capacity Mechanical Splice for Simultaneous Connection of Multiple Prestressing Strands

Product Introduction

The XQV YJM15L multi‑holes connector is a multi‑strand coupler designed for splicing groups of prestressing tendons in post‑tensioned concrete structures. It consists of an anchor head, connecting body and multiple wedges, providing reliable mechanical anchoring for several strands simultaneously. The connector ensures uniform force distribution, high anchorage efficiency (ηa ≥ 95%), and is compatible with φ15.2 mm low‑relaxation steel strands. It fully complies with GB/T14370‑2015, JT/T329‑2010, TB/T3193, ISO, CE, ASTM, BS and other international standards.

Key Features

🔗 Multi‑Strand Mechanical Anchoring

Simultaneously splices multiple strands (3‑19 holes) with high load capacity.

⚖️ Uniform Force Distribution

Ensures balanced tension between spliced strands, avoiding local overstress.

🔧 High Anchorage Efficiency

ηa ≥ 95%, fully compliant with international standards.

🏗️ Versatile Applications

Widely used in segmental bridges, high‑rise transfer floors, dams, and structural strengthening.

🛡️ Robust Construction

High‑strength alloy steel components (40Cr, 20CrMnTi) with corrosion protection.

Applications
  • Bridge Engineering:
    • Long‑span bridges (cable‑stayed, suspension): Continuous tensioning of prestressing tendons in main girders, pylons and piers; segmental casting or precast segment assembly – ensures uniform stress and overall stiffness.
    • Strengthening & reconstruction: Old bridge reinforcement, widening, load upgrading – new tendons anchored via multi‑hole connectors to improve bearing capacity and extend service life.
  • Building Engineering:
    • Large public buildings (stadiums, airport terminals): Anchor multiple tendons in long‑span roofs, beams, columns – reduces cross‑section size and optimises force distribution.
    • High‑rise transfer floors (thick slabs / open‑web trusses): Enhances crack resistance and load transfer between upper and lower structural systems.
  • Water Conservancy & Hydropower Engineering:
    • Dams, spillways, sluice floors and piers: Anchors multi‑directional tendons to resist water pressure and temperature stress – improves impermeability and sliding stability.
