HEAT INSULATION STRUCTURE, CRYOGENIC LIQUID STORAGE TANK HAVING THE SAME AND CONSTRUCTION METHOD FOR THE HEAT INSULATION STRUCTURE

摘要

PURPOSE: A heat insulation structure, a cryogenic liquid storage tank therewith, and a construction method thereof are provided to reduce thermal contraction by allowing the thickness of an adhesive layer to be uniform. CONSTITUTION: A heat insulation structure comprises outer insulation panels(210), inner insulation panels(220), sub barriers(240), middle insulation panels(250), adhesive layers(270), and support units. The outer insulation panels are coupled to the inner wall of a cryogenic liquid storage tank. The inner insulation panels are attached on the top of the outer insulation panel. The sub barriers cover gaps between the outer insulation panels. The middle insulation panels are coupled to the top of the sub barriers to cover the sub barriers. The adhesive layers are inserted between the sub barriers and the middle insulation panels. The support units are arranged in the middles of the adhesive layers and support one surface of the middle insulation panels.
