Abstract: Disclosed is a corner structure (100) of a liquefied gas storage tank, wherein the corner structure is installed at a corner of a storage tank for loading liquefied gas and supports sealing walls (51, 52) that prevent leakage of the liquefied gas. The corner structure (100) may include: two insulation members (110) arranged on the inner surface of a hull structure so as to be oriented in different directions; and mobile members (130) which are installed on the respective insulation members (110) and to which the sealing walls (51, 52) are joined. The mobile members (130) may be slidably coupled to the insulation members 110, and a plurality of the mobile members (130) may be arranged spaced apart from each other in a straight line on one of the insulation members.

Abstract: Disclosed is a corner structure (100) of a liquefied gas storage tank, the corner structure (100) being installed on a corner of a liquefied gas-carrying storage tank to support sealing walls (51, 52) that prevent the liquefied gas from leaking. The corner structure (100) comprises: two insulation members (110) arranged, oriented in different directions, on the inner surface of structural walls of a ship; and operational members (130) which are disposed on respective insulation members (110), and to which the support sealing walls (51, 52) adhere. The operational members (130) may be attached to the insulation members (110) so as to allow sliding against same.

Abstract: Disclosed is a corner structure of a liquefied gas storage tank, wherein the corner structure is installed at a corner of the storage tank for storing liquefied gas to support sealing walls. The corner structure includes: a stationary member secured to an inner surface of a hull structure wall; a movable member disposed on the stationary member such that the sealing walls are joined thereto; and an insulating member interposed between the sealing walls and the hull structure wall. The stationary member includes a stationary member body bent at a curved portion thereof in an opposite direction to the movable member, and the movable member includes a movable member body bent at a bent portion thereof in an opposite direction to the stationary member. The stationary member and the movable member are coupled to each other by a fastening member that penetrates the curved portion and the bent portion.
