The part 54 is inserted into the groove 22. In this state, when the operation shaft 53 is rotated by the clamp lever 55, as shown in FIG. 14, the inclined portions 54b of the both locking pieces 54a of the insertion portion 54 engage with the narrow openings 24, and The ten bent pieces 11 are pressed between the projecting portion 21 and the jig body 51.

  As described above, by tightening the jig 50, the bent piece 11 of the face material 10 is sandwiched between the projecting portion 21 and the jig 50 at a portion adjacent to the front and back surfaces of the projecting portion 21. A core material 30A (polyurethane foam) is filled in the space 1a formed by the frame material 20, and the double-sided material 10, the frame material 20 and the core material 30A are bonded (adhesion step: S-3A).

After the face material 10, the frame material 20, and the core material 30 are bonded as described above, the jig 50 is removed from the outer surface of the protrusion 21 of the frame material 20 (jig removal process: S-4A).
When the jig 50 is detached from the outer surface of the projecting portion 21 of the frame member 20, it is performed in the same manner as in the first manufacturing method, and the description is omitted.

  According to the method for manufacturing a laminated panel of the above-described embodiment, the jig 50 can be easily attached using the concave groove 22 having a substantially T-shaped cross section provided in the frame member 20 and the jig 50 is fastened. By this, the pair of face materials 10 and the frame material 20 and the core materials 30 and 30A can be bonded in a state where the positional shift between the frame material 20 and the face material 10 is eliminated, so that the lamination with both appearance and airtightness can be achieved. Panel 1 can be easily manufactured.
