<p><P>PROBLEM TO BE SOLVED: To provide a heat insulating and sound insulating structural body capable of making the thickness of the heat insulating and sound insulating structural body thin by using a vacuum heat insulating material. <P>SOLUTION: The heat insulating and sound insulating structural body 20 laminating a layer of a heat insulating and sound insulating material 21 and the flat plate-like vacuum heat insulating material 22 is formed on the surface of a hollow extrusion formed section 7. The vacuum heat insulating material 22 is so constituted that a plate-like core with heat insulation is wrapped with a sheet-like sealant to depress, the circumferential edge section of the sealant is sealed by heat welding to form and that the circumferential edge section of the other vacuum heat insulating material 22 is connected to the circumferential edge section. The thickness of the heat insulating and sound insulating structural body 20 can be thinned by using the vacuum heat insulating material 22 like this way and, at the same time, sticking construction work on the surface of the hollow extrusion formed section 7 can be carried out while loosening the heat insulating and sound insulating structural body 20 rolled in a rolled shape by deforming the circumferential edge section. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
