The present invention relates to a reef structure which is installed on the basis of a wreck put while being tilted on a seabed by being stranded or sunk in the sea. More specifically, the present invention relates to an artificial reef connected to a wreck hull, wherein the artificial reef comprises: a roof structure manufactured in a roof framework shape by using a forced frame to be arranged on the upper part of a wreck and a support leg arranged at regular intervals in the longitudinal direction of the wreck on the left and right outer parts of the wreck to float the roof structure in a pillar shape. A holder pipe having a regular arrangement interval is fixed and installed in a roof structure in a vertical direction in the width direction and the length direction of a wreck. Each holder pipe is provided with a stand pipe that is suspended while penetrating the holder pipe by a rope, a bolt, or the like. The reef structure is primarily installed so that the roof structure and the support leg have a tunnel shape surrounding the wreck. Each standpipe is lowered along the holder pipe to make the lower end side of the standpipe come in contact with the hull surface of the wreck. Therefore, the present invention can safely protect and grow various aquatic organisms inhabiting the surroundings of the wreck. According to the present invention, the benthos inhabiting the hull surface of the wreck are easily moved toward the reef structure along a stand pipe which also serves as a vertical spacer for the reef structure. The increasing effect of aquatic resources can be improved by invigorating the wreck which has been left as a scrapped ship.본 발명은 해상에서 좌초 또는 침몰되어 해저면에 기울어진 상태로 놓여져 있는 난파선을 베이스로 하여 시설되는 어초구조물에 관한 것으로서, 더욱 상세하게는 난파선의 상부에 배치되도록 강제프레임을 이용하여 지붕 골조 형상으로 제작되는 루프구조물과, 이 루프구조물을 기둥 형태로 떠받치도록 난파선의 좌,우 외측부에서 난파선의 길이 방향을 따라 일정 간격으로 배치되는 지지다리를 포함하되, 난파선의 폭 방향과 길이 방향에 걸쳐 일정한 배치간격을 가지는 홀더파이프를 루프구조물의 내측에 수직 방향으로 고정 설치하는 한편, 각각의 홀더파이프에는 로프나 볼트 등에 의하여 홀더파이프를 관통하는 상태로 매달리게 되
