Single Strand Coupler
Customization: can be customized
Composition: extruding anchors, bearing plate, spiral reinforcement, restraining ring.
Application: is used for connecting the single prestressed tendons in the post-tension or pre-tensioning method which can save a lot of steel strands.
Pre-tensioning construction procedure: first, stress the prestressed tendons to the designed control stress and fix the bars temporarily on a seat-typed steel mold with tooling anchorage, then pour in the concrete. Relax the tendons after the concrete reaches a desirable strength. By this method, the binding force of the bars and the concrete enables the concrete components to obtain prestress. With less process and high efficiency, the pre-tensioning method is easy to operate and ensures quality. It saves the permanent anchorage for anchoring the prestressing tendons.
The steel rebar connects coupler produced by our company include line-rod coupler, line-line coupler, and rod-rod coupler. These devices connect with material such as Φ25 precision rolled rebar as well as Φ12.7 and Φ15.2 strands, saving a large number of prestressed tendons for construction companies. These devices are safe, reliable, efficient, and material-saving.
