<p><P>PROBLEM TO BE SOLVED: To provide a building capable of preventing a powdery material from being scattered even if a vacuum heat insulation material using the powdery material as a core is used. <P>SOLUTION: A building comprises an inner wall 6 constituting an indoor space, the vacuum heat insulation material 5 fixed to the indoor side face of the inner wall 6 and a stab preventing board 7 fixed to the inner wall 6 with a fixing member 8 for hiding the vacuum heat insulation material 5 from the indoor side and protecting the vacuum heat insulation material 5 from the indoor side. The heat insulation material 5 is formed by arranging, between gas barrier covering materials individually having thermally fused layers disposed opposite to each other, a plurality of core members made from the powdery material and placed apart from each other with a predetermined interval in the direction approximately vertical to the thickness direction with evacuating and sealing the space accommodating the core materials. The core materials are disposed in individually independent evacuated spaces. The covering materials (thermal fusion layers) between the two adjoining core materials are thermally fused to each other. Therefore, working environment is prevented from becoming worse when the building is constructed, and contamination of a living space when the building is occupied can be avoided. The building can keep high heat insulation effect for a long time. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
