A heat insulation box body includes inner and outer boxes forming a shell of the heat insulation box body and triangular structural materials inserted in the shell held by close-contact by means of a vacuum. Further, at the time of disassembling the heat insulation box body after scrapping, a shell surface is cut and air is introduced into the inside of the shell to return the state of the shell to an atmospheric pressure state and then respective members are separated from each other.
1. A for disassembling a vacuum heat insulation box body having a shell constituted by inner and outer boxes, and structural materials disposed in said shell, said inner and outer boxes and said structural materials being fixed by close-contact caused by means of a vacuum, comprising the steps of:cutting a surface of said shell to thereby introduce air into the inside of said shell so as to allow the inside state of said shell to return to an atmospheric pressure state; and separating inner and outer boxes of said shell and said structural materials from...
