본 발명은 선체 내벽으로로부터 화물창의 내측 방향으로 2차 단열벽, 2차 방벽, 1차 단열벽 및 1차 방벽이 순차 적층되어 단열시스템이 구성되는 액화가스 화물창에 있어서, 1, 2차 단열벽 및 1, 2차 방벽이 단절되는 구간에 설치되며 리퀴드 돔을 형성하는 리퀴드 돔 박스; 1, 2차 단열벽과 리퀴드 돔 박스 사이에 발생하는 갭 내에 설치되는 연결부 단열박스; 및 연결부 단열박스의 상부에 설치되어 1차 방벽과 리퀴드 돔 박스의 내측면에 설치되는 돔 방벽을 밀봉 연결하는 인바스트립을 포함하고, 연결부 단열박스는 1, 2차 단열벽과 동일한 수준의 강성을 가짐으로써 갭 내에서 인바스트립을 지지하는 강도부재로서의 역할을 하는 것을 특징으로 하는 액화가스 화물창의 리퀴드 돔 연결부 구조를 제공하여, 화물창의 표준구역과 리퀴드 돔 구역을 연결하는 인바스트립에 벌지 발생을 최소화하고 리퀴드 돔 연결부에서의 피로수명이 저하되는 것을 방지한다.

    The present invention relates to a liquefied gas cargo hold, wherein a secondary insulation wall, a secondary barrier, a first insulation wall and a first barrier are sequentially stacked in a direction from the inner wall of a hull to the inside of a cargo hold so as to constitute an insulation system. In particular, provided in the present invention is a connecting part structure of the liquid dome of a liquefied gas cargo hold, which is characterized by comprising: a liquid dome box which is installed at a section where the first and second insulation walls and the first and second barriers are disconnected, and forms a liquid dome; a connecting part insulation box which is installed within the gap generated between the first and second insulation walls and the liquid dome box; and an invar strip which is installed at the upper portion of the connecting part insulation box so as to connect the first barrier to a dome barrier installed on the inner side surface of the liquid dome box in an airtight manner. Here, the connecting part insulation box has the same level of strength as that of the first and second insulation walls, thereby functioning as a strength member supporting the invar strip inside the gap. Therefore, the generation of a bulge at the invar strap connecting the standard section of the cargo hold to the liquid dome section can be minimized. In addition, the fatigue life can be prevented from being shortened at the liquid dome connecting part.
