The   parallel thread rebar coupler   is a steel sleeve for the mechanical joint which transmits the axial tension or pressure of the steel bar. The connection method of the parallel threaded rebar coupler is to strip off part of the longitudinal rib and transverse rib of the end of the steel bar by cutting with a wire rolling machine, and then roll directly into ordinary parallel thread, and connect with the special parallel rebar coupler to finish the connection of the steel bar. So, how do we check its connection quality? 1. Appearance inspection of construction quality: (1) Check whether the crimping pattern conforms to the plan, why the coupler rusts, and whether the coupler is under pressure. The small indentation of the joint shall conform to the standard. (2) There should be no visible cracks on the appearance of the joint.  (3) The curvature of the joint is 40. (4) At both ends of the joint, the steel bars have inspection marks. (5) During the appearance inspecti...

The  parallel thread rebar coupler  is one of the smallest and most effective coupler systems. It is widely used in projects that are large and high coupler volume. Both ends of the bars are enlarged, parallel threads are enlarged, parallel threads are cut into two sides two adapt the thread coupler. The couplers should be installed by tubes or wrenches. Calibration is not necessary. Paraller thread rebar couplers can produce full strength joints, yet they are the smallest of all couplers, which means they are the best choice for large projects that needs a large number of couplers. The end of each couplers are squares enlarged by cold forging, which increases the core diameter and makes sure that joints are stronger than pipes.
