The present invention provides an insulation wall securing device for an LNG storage tank. In the LNG storage tank with a double barrier structure, which includes a secondary insulation wall consisting of a plurality of secondary insulation panels fixed to an inner wall of a hull, and a primary insulation wall consisting of a plurality of primary insulation panels secured on an upper portion of the secondary insulation panels, the securing device for securing the primary insulation panel and the secondary insulation panel to each other comprises: a base socket secured on the upper portion of the secondary insulation panel; two or more studs having a lower end portion fastened to the base socket and having an upper end portion protruding upward; a setting plate having a through portion formed in the center thereof to accommodate all of the two or more studs, installed in the circumferential direction on the periphery of the two or more studs, and supported by a lower plate of the primary insulation panel; and a securing nut fastened to an upper end portion of each stud to secure the setting plate. Therefore, the insulation wall securing device increases the structural stability of the LNG storage tank.
