It is bent toward the second side to form bent pieces 5 and 6, and locking pieces 7 and 8 that lock each other are formed at the tips of the bent pieces 5 and 6. In this case, the outer skins 1 and 2 may be further molded into a pattern such as an uneven pattern, if necessary. A metal strip 14 is continuously supplied from an uncoiler 15 into the gap between the two continuously supplied outer skins 1 and 2, and a strip is provided on the inner surface of at least one of the outer skins 1. 14 are successively stacked. In the embodiment shown in the drawings, the material is laminated on the inner surface (the upper surface in FIG. 1) of the outer skin 1 which is continuously supplied at a lower position. That is, an adhesive such as a hot melt adhesive is applied to the continuously supplied strips 14 by an adhesive applicator 16.
The strip 14 is adhered to the inner surface of the skin 1 by a strip applicator 17, such as a pressure roller. In addition, the locking pieces 7 and 8 have a dogleg shape,
An adhesive is applied to at least one locking surface by an adhesive application device 19. In this way, the strip plate 3 is laminated on the inner surface of at least one of the two outer skins 1 and 2, and adhesive is applied to the locking surface of at least one of the locking pieces 7 and 8. The two outer skins 1 and 2 are sent to a double conveyor 9 via a preheating device 18. A foamed synthetic resin 3 is injected near the entrance of the double conveyor 9, foamed inside the double conveyor 9, and foamed and filled between the two outer skins 1 and 2. In this case, when entering the double conveyor 9, the locking pieces 7 and 8 of the upper and lower outer skins 1 and 2 are locked together and bonded with adhesive, so that the two sheets are held in the double conveyor 9. When the foamed synthetic resin 3 injected between the outer skins 1 and 2 foams, the foamed synthetic resin 3 does not leak from between the side edges of the outer skins 1 and 2, and as a result, unlike the conventional case, both sides of the double conveyor 9 It is no longer necessary to provide a side seal conveyor between the ends to prevent leakage of the foamed synthetic resin. After passing through the double conveyor 9, the third
As shown in the figure, a sandwich panel 4 is manufactured in which the outer skins 1 and 2 are fixed and bonded together using the locking pieces 7 and 8.

The sanderch panel 4 manufactured as described above is used, for example, as a panel constituting the shutter A of an opening in a building as shown in FIG. A hinge plate part 21 of a hinge 20 is attached to the surface of the outer skin 1 on one side.
At the same time, the fixing tool 22 inserted from the hinge plate part 21 is fixed to the band plate 14 via the outer skin 1, thereby connecting the sandwich panels 4 in a vertically foldable manner using the hinge 20.
