Disclosed is an insulation panel fixing apparatus of a liquefied natural gas (LNG) storage tank. According to the insulation panel fixing apparatus of an LNG storage tank, in an LNG storage tank of a dual barrier structure, in which a second insulation panel and a first insulation panel are successively piled up on an internal wall of a ship body, a second setting plate inserted into a coupler rod installed on an internal wall of the ship body is supported by a lower plate of the second insulation panel, and a second fixing nut is fastened with the coupler rod and the second setting plate is pressurized towards the internal wall of the ship body, thereby fixing the second insulation panel on the internal wall of the ship body. However, between the lower plate of the second insulation panel and the second setting plate, a cleat made of wood is placed, thereby preventing the lower plate of the second insulation panel from being damaged by the load generated in the LNG storage tank. The insulation panel fixing apparatus of an LNG storage tank is able to prevent the movement or deformation of the ship body from being transferred to the insulation wall.
LNG 저장탱크의 단열패널 고정장치가 개시된다. 본 발명에 따른 LNG 저장탱크의 단열패널 고정장치는, 선체 내벽에 2차 단열패널과 1차 단열패널이 순차적으로 적층되는 이중 방벽 구조의 LNG 저장탱크에 있어서, 선체 내벽에 설치되는 커플러 로드에 끼워지는 제2 세팅플레이트가 2차 단열패널의 하부 플레이트에 지지된 상태에서, 커플러 로드에 제2 고정너트를 체결하여 제2 세팅플레이트를 선체 내벽을 향한 방향으로 가압함으로써 2차 단열패널을 선체 내벽에 고정시키되, 2차 단열패널의 하부 플레이트와 제2 세팅플레이트 사이에 우드 소재로 제작되는 클리트(cleat)를 배치하여, LNG 저장탱크 내에서 발생하는 하중에 의해 2차 단열패널의 하부 플레이트가 손상되는 것을 방지한다.
