<p><P>PROBLEM TO BE SOLVED: To improve heat insulating property in a connection part of insulation panels. <P>SOLUTION: When insulation panels 181 are connected with frame members 184 butting on each other, substantially square wave shapes of the frame members 184 are mutually meshed. A heat insulating protective member 189 is provided on the fin-like peripheral part of a vacuum heat insulating material 185, and the end of the vacuum heat insulating material 185 is placed in a groove-shaped holding part 188 having substantially the same width as the thickness of the vacuum heat insulating material 185, which is formed on the protruding portion inner surface of the frame member 184. Further, when the insulation panels 181 are mutually connected, a core material 185a portion of the vacuum heat insulating material 185 of one insulation panel 181 is superposed on a core material 185a portion of the vacuum heat insulating material 185 of the other insulation panel 181 in the thickness direction of the insulation panels 181. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
