<p>PURPOSE:To shorten the work period and facilitate the disassembly/assembly by connecting a plurality of heat insulating wall members to each other and laminating them to form a heat insulating wall then suspending it in a space between an inner vessel and an outer vessel in the heat insulating wall of a double- hull low-temperature tank. CONSTITUTION:A heat insulating wall member 50 having wheels 12 is suspended from a guide rail 11 with the aluminum foil 7 surface facing an inner vessel 1, further the next heat insulating wall member 50 is suspended to this heat insulating wall member 50 in sequence to reach the floor surface, and they are fed to the peripheral direction in sequence. In addition, they are tightened and fixed to the inner wall of an outer vessel to form an insulating wall. Thereby, the work period is shortened, and disassembly/assembly is facilitated. Moreover, the heat insulating wall members are divided, thus convection is hard to occur inside, the heat insulation feature is excellent, no inner filler material is displaced, and the uniformity can be maintained.</p> |
