The present invention relates to a cryogenic insulation structure and a construction method thereof. According to the present invention, the cryogenic insulation structure comprises a plurality of sandwich panels, a joint spacer, a seamless foam insulation layer, and a seamless protection layer. Each of the plurality of sandwich panels includes a first insulation panel and a second insulation panel which is fixed on an outer side of the first insulation panel, and is fixed on a wall structure of a tank or a hull by a fixer. The joint spacer covers the installation part of the fixer, and fills a gap between the plurality of sandwich panels. The seamless foam insulation layer covers the whole outer surface of the plurality of sandwich panels and the joint spacer, is formed by a spray method, and comprises two or more layers. The seamless protection layer is located on an outer surface of the seamless foam insulation layer, comprises two or more layers, and is made of one of a semi-flexible insulation coating layer and a semi-flexible mastic. The present invention aims to provide the cryogenic insulation structure and the construction method thereof, which can provide improved thermal efficiency and be installed rapidly and efficiently.
극저온 단열 구조는 복수의 샌드위치 패널, 조인트 스페이서, 심리스(seamless) 발포 단열층, 및 심리스 보호층을 포함한다. 복수의 샌드위치 패널 각각은 제1 단열 패널과, 제1 단열 패널 외측에 고정된 제2 단열 패널을 포함하며, 고정구에 의해 탱크 또는 선체의 벽 구조에 고정된다. 조인트 스페이서는 고정구의 설치 부위를 덮으며, 복수의 샌드위치 패널 사이의 틈을 메운다. 심리스 발포 단열층은 복수의 샌드위치 패널과 조인트 스페이서의 외면 전체를 덮으며, 스프레이 방식으로 형성되고, 두 층 이상의 다층으로 구성된다. 심리스 보호층은 심리스 발포 단열층의 외면에 위치하며, 두 층 이상의 다층으로 구성되고, 반가요성 단열 코팅층과 반가요성 매스틱 중 어느 하나로 이루어진다.
