The present invention relates to a corner structure of a liquefied natural gas storage tank, which is capable of shortening construction time of the tank by simplifying an assembling structure and a manufacturing process, and efficiently resolving mechanical stress. The corner structure in accordance with an embodiment of the present invention, comprises: a fixed member (110) fixed on an internal surface of an edge of a storage tank; a movable member (130) supported on the fixing member to be able to move in a straight line; a stopping member (140) attached to the fixed member for preventing separation of the movable member from the fixed member; and a heat insulating member (150) disposed between a sealing wall and a ship body. In regards to this, the fixed member includes a guide part (114) on which a guide groove part (114a) is formed, and the movable member includes a guide protrusion part inserted into the guide groove part. In addition, since the width and length of the guide protrusion part are smaller than those of the guide groove part, the movable member can be supported on the fixed member to be able to move along a longitudinal direction and a direction perpendicular to the longitudinal direction.

    본 발명의 실시형태에 따른 코너 구조체는, 상기 저장탱크 모서리의 내부 표면에 고정되는 고정부재(110)와; 상기 고정부재 상에 직선이동 가능하게 지지되는 가동부재(130)와; 상기 가동부재가 상기 고정부재로부터 이탈되는 것을 방지하기 위해 상기 고정부재에 부착되는 멈춤부재(140)와; 상기 밀봉벽과 선체 사이에 배치되는 단열부재(150); 를 포함할 수 있다. 상기 고정부재는 안내홈부(114a)가 형성된 안내부(114)를 포함하고, 상기 가동부재는 상기 안내홈부에 삽입되는 안내돌기부를 포함하고, 상기 안내돌기부의 폭 및 길이는 상기 안내홈부의 폭 및 길이보다 작아, 상기 가동부재는 길이방향 및 상기 길이방향에 수직인 방향을 따라 이동 가능하게 상기 고정부재에 지지될 수 있다.
