The present invention relates to a coupler for a threaded steel bar to connect threaded steel bars to each other, not deformed bars on which ribs and nodes are formed. The coupler for a threaded steel bar comprises: a spiral inner screw unit formed on an inner circumferential surface; a spiral outer screw unit formed on an outer circumferential surface; and a plurality of node units separated from each other, formed on the outer circumferential surface in a longitudinal direction to cross the spiral outer screw unit, and provided with a door window formed on a middle thereof. A threaded steel bar is rotated and mounted into the spiral inner screw unit.
리브와 마디가 형성된 이형철근이 아닌 나사형철근을 서로 연결하기 위한 나사형철근용 커플러에 관한 것으로서, 상기 나사형철근용 커플러는 주면 형성된 나선형 내측나사부; 외주면에 형성된 나선형 외측나사부; 및 상기 나선형 외측나사부를 가로질러 길이방향으로 다수가 외주면에 서로 이격되어 형성되며 중앙부에 도어창이 형성된 마디부;를 포함하여, 상기 나선형 내측나사부에 나사형철근이 회전 체결되도록 하게 된다.
