ABSTRACT:
A mechanical connection for concrete reinforcing rods has a connecting sleeve and a reinforcing rods having protuberances (e.g., ribs or fins) on their outer surfaces. Each of the reinforcing rods has a threaded end for connection with the connecting sleeve, which has tapped portions for receiving the reinforcing rods. In one embodiment, a first end of a first reinforcing rod is passed completely through the sleeve, and the sleeve is then rotated about the end while simultaneously being screwed onto a second end of a second reinforcing rod. Upon tightening the connecting sleeve, the ends of the first and second reinforcing rods are placed in substantially coaxial, end-to-end arrangement, and are rotationally immobile. In a preferred embodiment, the connecting sleeve comprises a sheath having a conical bore, together with a conical socket in the form of two shell halves, which, when place together, provide two internal tapped portions having opposing threads.
