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. |
