Corner structure of liquefied gas storage tank

Disclosed is a corner structure (100) of a liquefied gas storage tank, in which the corner structure (100) is mounted on a corner of a storage tank for loading liquefied gas so as to support sealing walls (51, 52) for preventing leakage of liquefied gas. The corner structure (100) includes: a fixing member (110) fixed on an inner surface of a structural wall of a hull; a movable member (130) attached to the fixed member (110) and coupled to the sealing walls (51, 52); and a thermal insulation member (150) disposed between the sealing walls (51, 52) and a structural wall of the hull. The fixed member (110) includes a fixed member body (112) having a shape bent from a bent portion toward an opposite side of the movable member (130), and the movable member (130) includes a movable member body (132) having a shape bent from a bent portion toward an opposite side of the fixed member (110). 本发明公开一种液化气存储罐的隅角结构(100)，其中隅角结构(100)安装在用于装载液化气的存储罐的隅角上，以便支撑防止液化气泄漏的密封壁(51、52)。隅角结构(100)包括：固定构件(110)，固定在船体的结构壁的内表面上；可移动构件(130)，安
