액화가스 저장탱크의 단열벽을 형성하는 동시에 밀봉벽을 지지하도록 선체의 구조벽에 배치되는 단열 구조체가 제공된다. 단열 구조체(302)는, 밀봉벽이 연결될 수 있도록 형성되는 앵커 유닛(350)을 포함하며, 앵커 유닛(350)은, 단열 구조체의 상부 플라이우드(112)보다 아래쪽에 매립되고 상부 플라이우드와의 사이에서 간극을 형성하는 매립 플라이우드(352)와, 앵커 유닛의 조립시 위치결정을 위해 매립 플라이우드(352)에 삽입되는 위치결정 부재(354)와, 매립 플라이우드(352)와 상부 플라이우드(112) 사이에서 수평방향으로 슬라이딩 가능하게 배치되고 밀봉벽이 접합되는 슬라이딩부를 포함할 수 있다. 슬라이딩부와 단열 구조체의 하단표면 사이에는 단열재가 제공되고 열전달 통로로서의 앵커 로드가 존재하지 않는다.

    Provided is an insulation structure disposed on a structural wall of a hull to support a sealing wall and to form an insulation wall of a liquefied gas tank. The insulation structure (302) comprises an anchor unit (350) formed that a sealing wall can be connected. The anchor unit (350) includes an embedded plywood (352) embedded below an upper plywood (112) of the insulation structure and forming a gap between the upper plywood and the embedded plywood, a positioning member (354) inserted into the embedded plywood (352) for positioning the anchor unit (350) when assembling the anchor unit (350), and a sliding unit disposed to be slidable in a horizontal direction between the embedded plywood (352) and the upper plywood (112) and having the sealing wall bonded thereto. A heat insulation material is provided between a sliding unit and a bottom surface of an insulation structure, and an anchor rod is not provided as a heat transfer path.
