The present invention relates to an LNG tank insulation box assembly for an LNG ship. The LNG tank insulation box assembly comprises: a first insulation box assembly and a second insulation box assembly which are stacked in order toward the outside of an LNG tank; multiple protruding reinforcing members which protrude from the top surface of the second insulation box assembly, are extended in the longitudinal direction of a hull, are formed in a width direction of the hull at an interval, and are inserted into an insertion groove formed on the bottom of the first insulation box assembly; and a membrane which connects adjacent protruding reinforcing members on the top surface of the second insulation boxy assembly. In addition, a buffer member is included between the membrane and the first insulation box assembly. In the conventional method, reinforcing insulation box is partially used for preventing stress concentration due to a sloshing effect. However, the LNG tank insulation box assembly prepared by the present invention can simplify the internal arrangement of the LNG tank by unifying into a standard insulation box due to the existence of the buffer member included between the first insulation box assembly and the second insulation box assembly.

    본 발명은 LNG 선박의 LNG 탱크 단열박스 조립체에 관한 것으로서, LNG 탱크의 외부를 향해 차례로 적층 배치되는 1차 단열박스 조립체와 2차 단열박스 조립체; 상기 2차 단열박스 조립체의 상면에 돌출되며 선체의 길이방향으로 연장되고 상기 선체의 폭방향으로 이격되게 형성되며, 상기 1차 단열박스 조립체의 바닥에 형성된 삽입홈에 삽입되는 복수의 돌출 보강재; 및, 상기 2차 단열박스 조립체의 상면에서 상기 이웃하는 돌출 보강재 사이를 연결하는 멤브레인을 포함하되, 상기 멤브레인과 상기 1차 단열박스 조립체 사이에는 버퍼 부재가 개재되어 있는 것을 특징으로 한다. 이에 따라, 기존에는 슬로싱 효과에 의한 응력집중을 방지하기 위해 부분적으로 강화 단열박스를 사용하였으나, 1차 단열박스 조립체와 2차 단열박스 조립체 사이에 개재된 버퍼 부재의 존재로 인해 표준 단열박스로 일원화할 수 있기 때문에 LNG 탱크 내부의 배치를 단순화할 수 있는 이점이 있다.
