액화천연가스 저장탱크의 단열구조가 개시된다. 본 발명은 선체 내벽 상에 다수의 2차 단열패널이 배열되어 이루어지는 2차 단열벽과, 2차 단열벽 상에 설치되는 2차 밀봉벽과, 2차 밀봉벽 상에 다수의 1차 단열패널이 배열되어 이루어지는 1차 단열벽과, 1차 단열벽 상에 설치되는 1차 밀봉벽이 순차적으로 적층되는 액화천연가스 저장탱크에 있어서, 저장탱크의 코너부에 설치되어 1차 밀봉벽 및 2차 밀봉벽을 지지하는 트랜스버스 연결체; 및 트랜스버스 연결체와 선체 사이에 설치되어 트랜스버스 연결체를 지지하는 단열박스를 포함하고, 1차 단열패널 및 2차 단열패널은, 폴리우레탄 폼의 상면과 하면 중 적어도 어느 하나에 플라이우드 합판을 접착한 샌드위치 패널 형태로 마련되되, 1차 단열패널과 2차 단열패널 중에서 단열박스와 인접하게 배치되는 단열패널에 마련되는 플라이우드 합판은, 저장탱크의 코너측 방향으로 갈수록 두께가 증가하는 경사면을 포함하는 것을 특징으로 하는, 액화천연가스 저장탱크의 단열구조를 제공한다.

    Disclosed is an insulation structure for a liquefied natural gas storage tank. According to the present invention, in regard to a liquefied natural gas storage tank in which a secondary insulation wall formed by arranging a plurality of secondary insulation panels on an inner wall of a vessel body, a secondary sealing wall installed on the secondary insulation wall, a primary insulation wall formed by arranging a plurality of primary sealing walls on the secondary sealing wall, and a primary sealing wall installed on the primary insulation wall are sequentially stacked, the insulation structure includes: a transverse connection body installed in a corner part of the storage tank to support the primary sealing wall and the secondary sealing wall; and an insulation box installed between the transverse connection body and the vessel body to support the transverse connection body. The primary and secondary insulation panels are provided as a sandwich panel made by attaching plywood to at least one of the upper and lower surfaces of a polyurethane form, wherein the plywood placed on one, which is adjacent to the insulation box, of the primary and secondary insulation panels includes an inclined surface of which the thickness gets thicker while getting closer to a corner of the storage tank.
