Description

  The present invention relates to a holding member that holds a vacuum heat insulating panel on a mounting surface.

  Patent Document 1 describes a vacuum heat insulating panel in which a core material is accommodated between a pair of metal thin plates, and then the outer edges of the metal thin plates are joined by welding or the like. However, when assembling a plurality of vacuum heat insulating panels and fixing them to a wall surface or the like, a separate fixture is required.

  Patent Document 2 describes a vacuum heat insulating panel formed by joining and integrating a pressed first panel and a second panel by welding flange portions and evacuating an internal space. In this vacuum heat insulation panel, the vacuum heat insulation panels are assembled together by sandwiching the corners of the second panel from both sides with bolts and nuts.

  Patent Document 3 describes a vacuum heat insulating panel formed by evacuating the inside of a face material composed of a pair of flat plate-like main surface members and an end surface member inclined at 45 degrees with respect to the main surface members. ing. In this vacuum heat insulation panel, the vacuum heat insulation panels are assembled by overlapping and joining the end face members in a state inclined by 45 degrees with respect to the wall surface.

  However, in the vacuum heat insulation panel described in Patent Document 2, a gap is generated between the guide surfaces of the assembled vacuum heat insulation panel, and heat of the vacuum heat insulation panel is radiated from this gap. Moreover, in the vacuum heat insulation panel described in Patent Document 3, when a plurality of vacuum heat insulation panels are connected to each other in a planar shape by overlapping the end face members, if the vacuum heat insulation panel is not fixed by pressing means, there is a gap between the end face members. There is a risk that the heat of the vacuum heat insulation panel will be emitted from this gap.
