Disclosed is a structure for insulating a corner of a liquefied natural gas storage tank. According to the present invention, the liquefied natural gas storage tank allows a second insulation wall configured such that a plurality of second insulation panels are arranged on an inner wall of a hull, a second sealing wall installed on the second insulation wall, a first insulation wall configured such that a plurality of first insulation panels are arranged on the second sealing wall, and a first sealing wall installed on the first insulation wall to be stacked in order. The structure for insulating a corner of a liquefied natural gas storage tank can implement sealing of the tank without bending of corrugations at the corner of the storage tank by using an end cap sheet having a plurality of corrugations in an end cap shape on a flat metal sheet as a member for finishing a unit membrane forming the first sealing wall.
액화천연가스 저장탱크의 코너부 단열구조가 개시된다. 본 발명에 따른 액화천연가스 저장탱크는, 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, 1차 밀봉벽을 구성하는 단위 멤브레인을 마감하는 부재로써, 플랫(flat)한 금속시트 상에 엔드캡 형상의 주름이 다수 개 형성되는 엔드캡 시트를 사용함으로써, 저장탱크의 코너부에서 주름(corrugation)의 절곡됨 없이 탱크의 밀봉이 이루어진다.
