Document Type and Number:
Japanese Patent JP2020029873
Kind Code:
A
Abstract:
To provide a heat insulating floor structure between the inner tank and outer tank of a tank for storing liquefied gas, which can reduce radiant heat transfer and conductive heat transfer and also can improve heat insulating performance and strength.SOLUTION: A heat insulating floor structure formed between the bottom plate of an outer tank provided on a base and the bottom plate of an inner tank provided via a vacuum cooling layer inside the outer tank, comprises a lattice cross-sectional or circular pipe cross-sectional side wall vertically arranged on the vacuum cooling layer between the bottom plate of the outer tank and the bottom plate of the inner tank, and heat radiation shields provided horizontally in the side wall without any gap.SELECTED DRAWING: Figure 2
