SCREW-TYPE REBAR JOINT STRUCTURE OF DEFORMED REBAR AND MANUFACTURING METHOD THEREOF
A threaded reinforcing bar coupling structure (101) comprises a pair of reinforcing bars (102, 102) and a tubular coupler (104) connecting the pair of reinforcing bars (102, 102). Each of the reinforcing bars (102, 102) is a deformed reinforcing bar having spiral node portions (108) on an outer periphery of a reinforcing bar main body (106) having a round shaft shape. A cylindrical portion (114) with node portions (108) removed is formed on an end portion of the reinforcing bar (102), and a male threaded portion (112) is formed on the cylindrical portion (114). The male threaded portion (112) has hardness or tensile strength greater than that of a remaining portion of the reinforcing bar (102). The pair of reinforcing bars (102, 102) is connected by the screw tubular coupler (104) that is screwed onto the male threaded portions (112, 112).
