The present invention provides an insulation system of a liquefied gas storage tank with a double metal barrier structure, which includes: an insulating layer installed on an inner wall of a hull; a secondary barrier and a primary barrier installed adjacent to each other in succession on the upper part of the insulating layer and spaced apart from each other in a vertical direction; and an inter-barrier structure installed between the secondary barrier and the primary barrier. The inter-barrier structure includes: a plurality of support members for separating the primary barrier upwardly from the secondary barrier and supporting the barriers; and a connecting member for connecting the support members placed adjacent to each other. The inter-barrier structure is manufactured as an integrated set structure in which the two or more support members are fastened by the connecting members and is installed on the upper part of the secondary barrier. According to the present invention, the efficiency of installation and maintenance work is greatly improved by simplifying the shape and fastening method of the inter-barrier structure installed between the primary and secondary barriers of the liquefied gas storage tank.

    본 발명은 선체 내벽에 설치되는 단열층; 단열층의 상부에 연속하여 인접하게 설치되되 상하 방향으로 서로 이격되는 2차 방벽과 1차 방벽; 및 2차 방벽과 1차 방벽 사이에 설치되는 방벽 간 구조물을 포함하는 액화가스 저장탱크의 단열시스템에 있어서, 상기 방벽 간 구조물은, 1차 방벽을 2차 방벽으로부터 상측으로 이격시키고 지지하는 지지부재; 및 서로 인접하게 배치되는 지지부재 사이를 연결하는 연결부재를 포함하되, 상기 방벽 간 구조물은 2 이상의 지지부재가 연결부재에 의해 체결된 상태의 일체의 세트 구조물로 제작되어 2차 방벽의 상부에 설치되는 것을 특징으로 하는, 이중 금속 방벽 구조를 가지는 액화가스 저장탱크의 단열시스템을 제공한다. 본 발명에 의하면, 액화가스 저장탱크의 1, 2차 방벽 사이에 설치되는 방벽 간 구조물의 형상 및 체결 방식이 간소화됨에 따라 설치 및 유지보수 작업의 효율성이 크게 향상되는 효과가 있다.
