Rebar Splicing Coupler Parallel Threads 100 % Bar Break Upsetting End

Building use upsetting rebar coupler parallel threads with high tensile strength Introduction Multi-section bar when the steel joints, before the use of welding or lashing overlap, not only a waste of materials, and welding speed, welding quality is unstable, it is difficult to ensure the progress and quality of the project. Guangming Expressway extension line engineering design requirements, diameter ≥ 25mm reinforced with mechanical connections, combined with the project's
