Description

  The present invention relates to a heat insulating panel that constitutes a ceiling or a wall of a building such as a clean room or a warehouse, and a joining structure thereof.

  In general, for example, a heat insulating panel constituting a ceiling or a wall of a building such as a clean room or a warehouse is formed between a pair of surface plates, a frame material interposed between side surfaces of both surface plates, and both surface plates and the frame material. And a heat insulating core material made of, for example, polyurethane foam, which is injected and filled into the space to be formed.

  Conventionally, a frame member is formed of, for example, an extruded shape member made of synthetic resin or an injection-molded member, and is engaged with an engaging ridge or an engaging ridge formed in a substantially cross-sectional trapezoidal shape along the longitudinal direction thereof. Engagement ridges having a substantially inverted trapezoidal cross section are formed, and both ends of the engagement ridges and the engagement ridges extend perpendicular to both surface plates, and end plates of the surface plates are bent.
