XQV YJM15L Single Hole Connector – Prestressed Strand Coupler for Post‑Tensioning
High‑Strength Mechanical Splice for Reliable Force Transfer Between Strands
The XQV single‑hole connector achieves reliable splicing of prestressing steel strands through a mechanical anchoring design consisting of an anchor head, a connecting sleeve and wedges. It features flexible construction, efficient force transmission, and strong compatibility (suitable for different strand diameters such as φ15.2 mm and φ12.7 mm). The connector is widely used in various prestressed engineering projects. In practical applications, the appropriate model can be selected according to project requirements to ensure the safety and durability of the prestressed system. The product fully complies with GB/T14370‑2015, JT/T329‑2010, TB/T3193, ISO, CE, ASTM, BS and other international standards.
