The cross sectional area of the lead pass bar helps to produce a substantially continuous threaded rebar product without longitudinal ribs using standard rebar manufacturing tooling and equipment WO2012099638A1 Threaded rebar manufacturing process 2011 9 22 nbsp 0183 32 Take advantage of threaded couplers when connecting threaded sections of rebar The couplers work by providing two inputs for the threaded ends of the rebar sections In addition to providing an inexpensive and secure way to connect sections of rebar the couplers can be removed and reused on other sections of rebar in the event of damage to either of the Referring to the drawings the lengths of rebar indicated at 10 and 11 each have a helical threaded configuration occupying the entire peripheral surface Viewed from the side the thread pattern responsible for this surface configuration has a generally semi circular cross section as indicated at Straight Threaded Coupler with Upset Rebar Ends This is a mechanical splice consisting of forming heads on the ends of the bars to be connected using a hydraulic machine from the splice manufacturer which is designed to fit between closely spaced bars 2010 3 31 nbsp 0183 32 Also it appears to be a Williams bar RE rebar all thread vs deformed If the threaded bar conforms to ASTM A615 the threads meet the requirements for deformations This would not be the case for typical quot all thread quot which has cut machine threads rather than large forged rolled threads
