The present invention provides a fixing device for a membrane-type liquefied gas insulation system. A membrane-type liquefied gas insulation system includes: an insulation layer installed on an inner wall of a hull; a secondary barrier installed in the upper part of the insulation layer; a first barrier installed at intervals in the upper part of the secondary barrier; and a structure between barriers, arranged between the secondary barrier and the first barrier. The fixing device for a membrane-type liquefied gas insulation system includes: a first coupling unit fixed to the upper surface of the secondary barrier by welding; and a second coupling unit fixing the structure between the barriers by being inserted into and coupled to the inner side of the first coupling unit. According to the present invention, the fixing device for a membrane-type liquefied gas insulation system has excellent structural stability by having a structure that does not penetrate the membrane and has excellent installation efficiency by having a simplified shape and coupling method. Moreover, the fixing device for a membrane-type liquefied gas insulation system is easy to repair after installation.

    본 발명은 선체 내벽에 설치되는 단열층과 상기 단열층의 상부에 설치되는 2차 방벽과 상기 2차 방벽의 상부에 이격되어 설치되는 1차 방벽 그리고 상기 2차 방벽과 상기 1차 방벽 사이에 배치되는 방벽간 구조물을 포함하는 멤브레인형 액화가스 단열시스템에 있어서, 2차 방벽의 상면에 용접에 의해 고정되는 제1 체결유닛; 및 제1 체결유닛의 내측으로 삽입 체결되며 상기 방벽간 구조물을 구속하는 제2 체결유닛을 포함하는 멤브레인형 액화가스 단열시스템의 고정장치를 제공한다. 본 발명에 따른 멤브레인형 액화가스 단열시스템의 고정장치는, 멤브레인을 관통하지 않는 구조로서 구조적 안정성이 우수하고 형상 및 체결 방식이 단순화됨에 따라 설치 효율이 뛰어나며 설치 이후에도 보수/수리가 용이한 효과를 가진다.
