摘要： Disclosed is a parallel-tapered-integrated screw-coupling structure for connecting reinforcing bars. In the screw-coupling structure between an internally-threaded body and an externally-threaded body, for connecting reinforcing bars: the internally-threaded body comprises, on the inner diameter thereof, a parallel-tapered-integrated internal thread section formed by integrating a parallel internal thread section formed as a parallel screw thread, with a tapered internal thread section formed on one end of the parallel internal thread section so that the minor diameter thereof gradually narrows; and the externally-threaded body comprises, on the outer diameter thereof, a parallel-tapered-integrated external thread section formed by integrating a parallel external thread section formed as a parallel screw thread, with a tapered external thread section formed on one end of the parallel external thread section so that the major diameter thereof gradually narrows, wherein the minor diameter of the parallel internal thread section is formed so as to be greater than the maximum minor diameter of the tapered internal thread section, the major diameter of the parallel external thread section is formed so as to be greater than the maximum major diameter of the tapered external thread section, a screw thread discontinued section is formed between the parallel internal thread section and the tapered internal thread section, and between the parallel external thread section and the tapered external thread section, and the minor diameter of the parallel internal thread section is formed so as to be greater than the maximum major diameter of the tapered external thread section.
