And a heat insulating core material made of, for example, foamed polyurethane, which is injected and filled into the space.

  When the heat insulation panel configured as described above is used as, for example, a panel for a ceiling, the adhesiveness between the surface plate and the heat insulation core decreases due to aging deterioration of the heat insulation core material, and the heat insulation performance deteriorates due to separation of the surface plate and the heat insulation material. There is a risk of doing.

After the through hole 9c is formed in the inner vertical piece 3d and the bent pieces 10 and 11, one end of the wire 8 is inserted from the outside of the panel through the through hole 9c of the bent piece 10 and inserted into the panel. To the inside of the through hole 9c of the bent piece 11 and is taken out of the panel. Then, as described above, knots 8a are formed at both ends of the wire 8 and connected to the bent pieces 10 and 11. In this way, a plurality of panels are flattened via a surface plate and a spacer, and the frame material 3A is placed in the space formed by the top plate 1 and the bottom plate 2 and the frame material 3A of each flatly stacked panel. A panel PC is manufactured by injecting and filling the thermal insulation core material 5 from an injection port (not shown) provided.

  As shown in FIG. 7A, in the joining structure of panel PCs, the wires 8 attached to one panel PC and the other panel PC are embedded in the heat insulating core material 5 of each panel PC, and both end portions are Since it is connected with the bent pieces 10 and 11 of the upper and lower surface plates 1 and 2, it does not become an obstacle when joining with other heat insulating panels.

  In the third embodiment, the other parts are the same as those in the first embodiment described above. Therefore, the same parts are denoted by the same reference numerals and description thereof is omitted.

  According to the panel PC used for the ceiling structure configured as described above, the bent pieces 10 and 11 of the lower surface plates 1 and 2 are connected by the wire 8, so that the connecting member is provided on the outer surface side of the lower surface plate 2. Since a certain wire 8 is not exposed and is not seen from below, it is a heat insulating panel with excellent aesthetics.

  Further, since the upper and lower plates 1 and 2 can be reliably connected by the wire 8, the adhesion between the upper and lower plates 1 and 2 and the heat insulating core material 5 can be secured over a long period of time, and the heat insulating performance can be maintained.

  Furthermore, since the wire 8 is embedded in the heat insulating core material 5 and both ends are connected to the bent pieces 10 and 11 of the upper and lower surface plates 1 and 2, the panel does not become an obstacle when the wire 8 is joined to other heat insulating panels. Since it can be accommodated inside the PC, it is possible to maintain the heat insulation performance by securing the adhesion between both panels.
