액화가스 저장탱크의 단열벽을 형성하는 동시에 밀봉벽을 지지하도록 선체의 구조벽에 배치되는 단열 구조체가 제공된다. 상기 단열 구조체는, 상기 구조벽(H) 상에 설치되는 2차 단열패널(130)과; 상기 2차 단열패널 상에 부착되는 1차 단열패널(110)과; 상기 밀봉벽이 연결될 수 있도록 상기 1차 단열패널에 형성되는 앵커 유닛(150); 을 포함할 수 있다. 상기 밀봉벽은 1차 밀봉층(202) 및 2차 밀봉층(204)으로 이루어지며, 상기 1차 밀봉층 및 상기 2차 밀봉층은 상기 앵커 유닛에 의해서 상기 1차 단열패널 상에 적층 설치되며, 상기 2차 단열패널은 내부에 격자구조의 칸막이 부재가 설치되어 형성될 수 있다.
Provided is an insulation structure which is arranged on a structural wall of a vessel to support a sealing wall while forming an insulation wall of a liquefied gas storage tank. The insulation structure may comprise: a secondary insulation panel (130) installed in the structural wall (H); a primary insulation panel (110) attached on the secondary insulation panel; and an anchor unit (150) formed on the primary insulation panel in order to connect the sealing wall. The sealing wall is composed of a primary sealing layer (202) and a secondary sealing layer (204), and the primary sealing layer and the secondary sealing layer are laminate-installed in the primary insulation panel by the anchor unit. The secondary insulation panel can be formed with a partition member of a lattice structure installed inside. According to the present invention, the density of a part of the insulators forming the insulation structure is reduced in order to reduce weight and improve insulation performance, and a stiffening member is arranged inside the insulation structure to maintain strength.
