Zusammenfassung:Disclosed is a coupling unit of a cargo barrier structure that is capable of effectively coping with the application of various forces like the generation of shrinkage displacement by a cryogenic fluid or the behavior of a ship body, thereby enhancing the performance of the carrier barrier structure. According to the present invention, the coupling unit of a cargo barrier structure includes: a base member disposed on top of the inner wall of a ship body; a first coupling bolt vertically fixed to the top of the base member; a first joint having a first flat portion coupled to the first coupling bolt and first support portions extended upward from both ends of the first flat portion; a second joint coupled between the first support portions by means of a second coupling bolt; a third joint having a second flat portion, second support portions extended downward from both ends of the second flat portion, and a third coupling bolt for coupling the second support portions and the second joint to cover the top of the second joint with the second flat portion; a fixing bolt vertically fixed to the top of the third joint; and a fastener fastened to the fixing bolt to pressurize a lower protection plate of a lower insulating board disposed between the inner wall of the ship body and a secondary barrier. 화물창 방벽구조의 결합유닛이 개시된다. 본 발명의 실시 예에 따른 화물창 방벽구조의 결합유닛은 선체 내벽 상부에 배치되는 베이스부재; 베이스부재 상부에 수직 고정되는 제1결합볼트; 제1결합볼트에 결합되는 제1평탄부 및 제1평탄부 양단으로부터 상방향으로 연장 형성된 제1지지부를 포함하는 제1조인트; 제2결합볼트에 의해 제1지지부 사이에 결합된 제2조인트; 제2평탄부 및 제2평탄부 양단으로부터 하방향으로 연장 형성된 제2지지부를 포함하고, 제2평탄부에 의해 제2조인트 상부를 커버하도록 제3결합볼트에 의해 제2지지부가 제2조인트와 결합되는 제3조인트; 제3조인트 상부에 수직 고정되는 고정볼트; 및 선체 내벽과 2차방벽 사이에 배치된 하부단열보드의 하부 보호판을 가압하도록 고정볼트에 체결되는 체결부;를 포함하되, 제1조인트 내지 제3조인트 중 하나 이상은 힘이 작용할 경우 회전 변위가 가능하도록 각각 제1결합볼트 내지 제3결합볼트 중 하나 이상과 결합되는 부위에 관통된 형상의 결합홈을 형성한다.
