The present invention relates to a heat insulation structure of a liquefied gas storage tank for insulating liquefied gas stored inside a tank body. According to the present invention, the heat insulation structure of a liquefied gas storage tank comprises: studs spaced apart from each other at regular intervals on an outer surface of the tank body; a spacer coupled to an outer circumferential surface of the stud so as to come into contact with the outer surface of the tank body; a seat unit installed on the spacer to surround and surround the tank body; and a heat insulating layer formed by spraying a spray foam heat insulating material on the seat unit. The spacer has a predetermined thickness and is positioned between the seat unit and the tank body, and a leak detection space capable of detecting leakage of liquefied gas is formed between the tank body and the seat unit.

    본 발명은 탱크 몸체 내부에 저장된 액화가스를 단열하기 위한 액화가스 저장탱크의 단열구조에 관한 것으로, 상기 탱크 몸체의 외면에서 일정 간격으로 서로 이격되게 설치되는 스터드; 상기 탱크 몸체의 외면에 맞닿도록 상기 스터드의 외주면에 결합되는 스페이서; 상기 스페이서 상에서 상기 탱크 몸체를 둘러 감싸도록 설치되는 시트부; 및 상기 시트부 상에 스프레이 폼 단열재가 분사되어 형성되는 단열층을 포함하고, 상기 스페이서는 소정의 두께를 갖고 상기 시트부와 상기 탱크 몸체 사이에 위치되어, 상기 탱크 몸체와 상기 시트부 사이에 액화가스의 누설을 감지할 수 있는 누설감지용 공간이 형성된다.
