Disclosed is an insulation structure for a liquefied natural gas storage tank. According to the present invention, the liquefied natural gas storage tank alternatively arranges insulation panels forming a first insulation wall and a second insulation wall so that the insulation panels deviate from each other. Therefore, a convective process can be decreased through a gap between the insulation panels so that insulation performance can be improved. Also, the first insulation wall and the second insulation wall are mechanically fastened to each other. Therefore, an excessive shear load can be prevented from being generated on a membrane layer of a second sealing wall caused by a heat shrinkage difference between the first insulation wall and the second insulation wall.

    액화천연가스 저장탱크의 단열구조가 개시된다. 본 발명에 따른 액화천연가스 저자애탱크는, 1차 단열벽 및 2차 단열벽을 이루는 단열패널들을 서로 어긋나도록 교차 배치시킴으로써 단열패널 간의 갭을 통한 대류 작용이 감소되어 단열 성능이 향상되고, 더불어 1차 단열벽과 2차 단열벽을 서로 기계적으로 체결함으로써 1차 단열벽과 2차 단열벽의 열수축량 차이로 인해 2차 밀봉벽의 멤브레인 층에 과도한 전단 하중이 발생하는 것을 방지한다.
