Round threaded rebar couplers are made of steel seamless tube or solid steel rod, suitable to connect two sections of reinforced bar to extend the length,used in the reinforced concrete site, reinforcement construction works and reinforced bar mesh projects. One end of rebar is turned by the lathe and made external thread by threading machine. Both threaded ends are screwed into rebar coupler for connecting by torque wrench tool.
During concrete pouring, often encountering the concrete can not pass through the reinforcement grid, the mechanical rebar couplers connecting effectively doubles the ratio of reinforcement to concrete to prevent concrete blockage and limiting the flow and distribution of larger aggregate particles and improve effectiveness of vibration reinforcement.
Also being used to connect all threaded rod, mechanical bot or stud as all thread coupler. The end-to-end connection provides many advantages of continuous connecting and more reliable than lap joints ensures precise and stable connection and make the installing quicker and easier.
★ Without expansion function, Have connecting and fixing.
★ Tap full internal thread of Metric, Inch, Rd and RB inside.
★ Pre make external thread on the end of reinforced bar by threading machine, after turning by lathe.
★ Also being used to connect all threaded rod, bolt or stud.
★ Securer and firmer than the lap joint or welding connecting.
