Disclosed is a corner part insulation structure for a liquefied natural gas storage tank. A liquefied natural gas storage tank, in which a secondary insulation wall formed by arranging a plurality of 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 insulation panels on the secondary sealing wall, and a primary sealing wall installed on the primary insulation wall are sequentially stacked, includes a corner part assembly completing the sealing of the storage tank by finishing the edge of the primary sealing wall in a corner part of the storage tank. The corner part assembly includes an end cap sheet sealing four corners of the primary sealing wall installed on each side of the storage tank by finishing the corners. The end cap sheet comprises: an end cap wrinkle of an end cap shape finishing wrinkles formed on the primary sealing wall; and a long wrinkle extended in a direction orthogonal to a direction in which the end cap wrinkle is extended. Therefore, the corner part insulation structure is capable of having excellent insulation performance and improving productivity.
액화천연가스 저장탱크의 코너부 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 코너부에서 1차 밀봉벽의 가장자리를 마감하여 저장탱크의 밀봉을 완성시키는 코너부 어셈블리를 포함하고, 코너부 어셈블리는, 저장탱크의 각 면에 설치되는 1차 밀봉벽의 네 모서리를 마감하여 밀봉시키는 엔드캡 시트를 포함하며, 엔드캡 시트에는, 1차 밀봉벽에 형성되는 주름을 마감하는 엔드캡 형상의 엔드캡 주름; 및 엔드캡 주름이 연장되는 방향과 직교하는 방향으로 연장되는 긴 주름이 형성되는 것을 특징으로 한다.
