XQV BJM15L Connector – Prestressed Strand Coupler for Post‑Tensioning Systems
Multi‑Strand Connector for Reliable Force Transfer in Prestressed Structures
The XQV BJM15L connector is mainly used to connect prestressed strands (PC strands). It ensures effective force transfer between strands, which is crucial for structural stability and strength. The connector transmits prestressing force from the tensioning end to the fixed end, ensuring uniform stress distribution and preventing local stress concentrations and deformations.
The protection cover and corrugated pipe protect the prestressed strands from external damage, extending service life. Spiral reinforcement and limit rings enhance the connector’s strength and stability, increasing the structure’s load‑bearing capacity. The connecting body ensures a firm connection among components, enabling the structure to withstand external loads reliably.
