REINFORCING BAR COUPLER BASED ON DOUBLE ACTION OF SCREW ELEMENTS
Most of the reinforcing bars used in reinforced concrete industry have outwardly circumferential ribs. The common form of these ribs, are the inclined shape ribs. In addition, a pair of longitudinal ribs may be formed as a result of the manufacturing process. Despite the importance of these ribs in increasing the bond between it and the surrounding concrete, it represents one of the most important obstacles in finding a strong and small size mechanical coupler to connect two or more bar ends. These ribs significantly reduce the contact surfaces needed to transfer loads and stresses between the reinforcing bars and the inner surface of the mechanical coupler. Presented herein, apparatuses and methods for coupling reinforcing bars based on double action of screw elements and bar end threading without enlargement or undercut. The rebar outwardly circumferential ribs and the inner surface of the mechanical coupler tubular sleeve, are machined to form an interlock between them which significantly enhance the coupling strength. When the screw elements are tightening against a reinforcing bar, the machining that done, make the circumferential surface of the rebar end between the ribs not only in direct contact but also dig into the inner surface of the mechanical coupler and does eliminate the spaces between them. Means for coupling and gripping the tubular sleeve body over the ends reinforcing bar ends.
