Abstract

본 발명은 철근의 외주면에 홈이 더 형성되되, 상기 홈이 철근의 길이방향으로 형성되고 철근의 외주면에서 내부측으로 갈수록 좁아지는 테이퍼홈으로 형성되어 있으며 테이퍼홈으로부터 연장되는 돌출부가 더 형성되어 있음에 따라, 이들에 의해 철근의 배근작업시에 철근들이 서로 미끄러지는 것이 방지될 수 있으며, 철근의 체결력과 묶음력 및 콘크리트와의 접합력을 크게 향상시키고, 굵기와 강도를 조절하여 철근을 다양하게 제작할 수 있을 뿐만 아니라, 철근을 제조하는 제조과정에서 테이퍼홈이 바로 철근의 외주면에 형성될 수 있어 철근의 버려짐이 생략되고 철근의 외주면에 형성된 테이퍼홈만큼 철근 원자재가 절약되어 철근 제조에 따른 자원 절감효과를 기대할 수 있는 홈이 형성된 철근을 제공하고자 한다. 이를 위해 본 발명은, 철근에 있어서, 상기 철근(10)의 외주면에는, 상기 철근(10)의 길이방향으로 길게 요입형성되되, 철근(10)의 외주면에서 내부측으로 갈수록 좁아지는 테이퍼홈(11)들과, 상기 테이퍼홈(11)들 사이에 이들 테이퍼홈(11)으로부터 연장되는 돌출부(12)가 더 형성되어 이루어진다. 또한, 상기 테이퍼홈(11)들과 돌출부(12)의 외면에는 각각 이들 테이퍼홈(11)들과 돌출부(12)를 감아 포설하는 보조돌출부(13)가 더 형성되어 이루어진다.
