The present invention relates to an insulation system for a liquefied gas storage tank, in which a second barrier and a first barrier are sequentially installed at the upper portion of an insulation layer. In particular, provided is a corner structure of an insulation system for a liquefied gas storage tank, which comprises: a lower corner panel which is installed at the inner wall of a hull after being bent at the same angle as the angle formed by two inner wall surfaces of the liquefied gas storage tank at the corner of the liquefied gas storage tank; a foam block which is installed at the bent portion of the upper side of the lower corner panel; a pair of hardwood blocks which are arranged to be adjacent to the side surface of the foam block at the upper portion of the lower corner panel while being individually installed on the two inner wall surfaces of the liquefied gas storage tank; a pair of second corner steels which are installed at the upper portion of the hardwood block and have the distal end of the second barrier connected by welding; a second angle sheet which connects the gap between the pair of second corner steels to finish the same by sealing; a corner plywood which is installed at the upper portion of the second corner steel; a pair of first corner steels which is installed at the upper portion of the corner plywood and has the distal end of the first barrier connected by welding; and a first angle sheet which connects the gap between the pair of first corner steels to finish the same by sealing. The present invention is a structure in which a member connecting the barrier is separated in each load direction at the corner of the insulation system of the liquefied gas storage tank. Therefore, when the thermal contraction load is produced at the membrane constituting the barrier, response may be provided for each load direction, thereby significantly improving structural performance.

    본 발명은 단열층의 상부에 2차 방벽과 1차 방벽이 순차적으로 설치되는 액화가스 저장탱크의 단열시스템에 있어서, 액화가스 저장탱크의 코너부에서 액화가스 저장탱크의 두 내벽면이 이루는 각도와 동일한 각도로 절곡되어 선체 내벽에 설치되는 하부 코너패널; 하부 코너패널의 상측 절곡 부위에 설치되는 폼 블럭; 하부 코너패널의 상부에서 폼 블럭의 측면에 인접하게 배치되되 액화가스 저장탱크의 두 내벽면 상에 각각 설치되는 한 쌍의 하드우드 블럭; 하드우드 블럭의 상부에 설치되며 2차 방벽의 끝단이 용접에 의해 연결되는 한 쌍의 2차 코너스틸; 한 쌍의 2차 코너스틸 사이를 연결하여 밀봉 마감하는 2차 앵글시트; 2차 코너스틸의 상부에 설치되는 코너 플라이우드; 코너 플라이우드의 상부에 설치되며 1차 방벽의 끝단이 용접에 의해 연결되는 한 쌍의 1차 코너스틸; 및 한 쌍의 1차 코너스틸 사이를 연결하여 밀봉 마감하는 1차 앵글시트를 포함하는, 액화가스 저장탱크 단열시스템의 코너부 구조를 제공한다. 본 발명은 액화가스 저장탱크 단열시스템의 코너부에서 방벽을 연결하는 부재가 하중 방향별로 분리되어 있는 구조로서, 방벽을 구성하는 멤브레인에 열수축 하중 발생시 각 하중 방향별로 대응이 가능하여 구조적 성능이 현저히 향상되는 효과가 있다.
