Disclosed is an insulation structure for a cargo hold that can effectively support the load applied to the insulation structure and reinforcing the insulation structure. According to an embodiment of the present invention, an insulation structure for a cargo hold comprises: an open-cell layer which surrounds the outer surface of a primary barrier in contact with cryogenic fluid inside the cargo hold and forms a leak path so that the fluid leaked through the primary barrier can flow; and a closed-cell layer laminated on top of the open-cell layer to cover the open-cell layer. In the open-cell layer, support blocks to support the load are placed at set intervals, and the support blocks are made of closed-cell material.
화물창의 단열구조가 개시된다. 본 발명의 실시 예에 따른 화물창의 단열구조는 화물창 내부의 극저온 유체와 접촉되는 1차방벽의 외면을 감싸며, 1차방벽을 통해 누출된 유체가 흘러갈 수 있도록 리크패스를 형성하는 오픈셀층; 및 오픈셀층을 덮도록 오픈셀층의 상부에 적층된 클로즈드셀층;을 포함하되, 오픈셀층에는 하중을 지지하기 위한 지지블록이 설정 간격으로 배치되며, 지지블록은 클로즈드셀 소재로 제작된다.
