본 발명은 액화가스 저장탱크 및 이를 포함하는 선박에 관한 것으로, 본 발명의 액화가스 저장탱크는, 1차방벽, 1차단열벽, 2차방벽, 2차단열벽으로 이루어지는 극저온 물질을 저장하는 액화가스 저장탱크로서, 상기 1차단열벽은, 상기 2차단열벽, 상기 2차방벽, 상기 1차단열벽의 일부인 고정단열벽이 적층되어 이루는 단위 요소가 이웃하여 배치된 상태에서, 이웃하는 상기 고정단열벽 사이의 공간 부분에 마련되는 연결단열벽을 포함하고, 상기 고정단열벽에서 상기 연결단열벽과 마주하는 측면에 형성되는 제1포지티브 단차부; 상기 연결단열벽에서 상기 고정단열벽과 마주하는 측면에 형성되는 제1네거티브 단차부; 이웃하는 상기 고정단열벽 사이에 상기 연결단열벽을 삽입 설치했을 때, 상기 제1포지티브 단차부 상에 상기 제1네거티브 단차부가 중첩되어 형성되는 제1슬릿; 및 상기 제1포지티브 단차부 상에 접착되고, 상기 연결단열벽이 이웃하는 상기 고정단열벽 사이에 설치될 때, 상기 연결단열벽에 접착되지 않는 상태로 상기 제1네거티브 단차부에 의해 압착되어 상기 제1슬릿의 공간 부분을 차단하는 제1단열패드를 포함할 수 있다.

    The present invention relates to a liquefied gas storage tank and a vessel including the same. The liquefied gas storage tank of the present invention includes a corner block disposed on a corner portion, in which a first surface and a second surface having different angles meet each other and form a storage space for accommodating liquefied gas. The corner block comprises a lower block provided inside the first and second surfaces and consisting of a single board, an upper block bonded to a secondary wall of the lower block, and an upper connection block bonded to the secondary wall on an upper surface of a neighboring lower block to connect lower blocks. The upper connection block includes: a first corner connection fixing unit and a second corner connection fixing unit which are provided inside the first surface and the second surface, respectively, are bonded to the secondary wall, and have a structure, in which a first corner connection plywood, a corner connection insulator, and a second corner connection plywood are stacked; and a corner connection curved unit which is installed in a corner space between the first corner connection fixing unit and the second corner connection fixing unit. The corner connection curved unit may have both side surface heights perpendicular to the secondary wall lower than an overall height of each of the first corner connection fixing unit and the second corner connection fixing unit. Accordingly, the present invention can improve the structure of the corner block to reduce a low temperature burden, a sloshing burden, and a stress burden on the corner secondary wall.
