The connection between the heat insulating material 1 and the interior material 2 can also be performed by applying an adhesive between them. However, without applying such a trouble, since both by pushing Dari screwed mounting pins 3 overlapping the heat-insulating material 1 and the interior material 2 can be easily connected, the labor of the manufacturing interior insulating panel A ₁ Can be reduced.

  Each mounting pin 3 penetrates the heat insulating plate 1, and the tip portion is exposed on the other surface side of the heat insulating plate 1 (the side opposite to the interior material 2). As will be described later, the exposed tip portion of the mounting pin 3 is a portion that is adhered and gripped to the concrete constituting the ceiling slab 4. The mounting pin 3 is preferably a screw-like one in which a screw is cut at least at the tip portion so as to obtain a high bonding strength with concrete.

The heat insulating plate 1 and the interior material 2 have a rectangular shape, and the side edges on both long sides of the interior material 2 are respectively folded to the side surfaces of the corresponding heat insulating plate 1 to increase the rigidity of the heat insulating panel A ₁ for interior use.
