SCREW-TYPE REBAR JOINT STRUCTURE OF DEFORMED REBAR AND MANUFACTURING METHOD THEREOF
A threaded reinforcing bar coupling structure comprises a pair of reinforcing bars and a tubular coupler connecting the pair of reinforcing bars. Each of the reinforcing bars is a deformed reinforcing bar having spiral node portions on an outer periphery of a reinforcing bar main body having a round shaft shape. A cylindrical portion with node portions removed is formed on an end portion of the reinforcing bar, and a male threaded portion is formed on the cylindrical portion. The male threaded portion has hardness or tensile strength greater than that of a remaining portion of the reinforcing bar. The pair of reinforcing bars is connected by the screw tubular coupler that is screwed onto the male threaded portions.
