ていた。2. Description of the Related Art Conventionally, a laminated panel used as a floor member of a railway vehicle, a door for interior fittings, or a building material has been constructed by placing a core material between two face plates and adhering them together. . It is also considered to use the laminated panel as a vehicle body of a railway vehicle or an outer wall of a building. Such a laminated panel has a structure in which each face plate and a core material are joined by a brazing material made of metal. In these laminated panels, the core material may have various shapes such as a honeycomb shape, a lattice, and a continuous triangle, but basically, a thin plate-shaped material is sequentially bent and the respective plate materials are arranged and joined. In such a core material, the bent sides are basically parallel, and the panel as a whole is basically formed in a flat plate shape.

る。Therefore, when the above-mentioned panel is used for the curved surface, the panel is forcibly bent and used. In the method of performing such processing, the core material or the face plate may be deformed, which may reduce the strength of the panel itself. A technique described in Japanese Patent Laid-Open No. 1-181931 is known to solve such a problem. That is, a curved surface mold is arranged in a high temperature and high pressure autoclave, and a laminated panel is adsorbed to the curved mold to manufacture the same. Alternatively, the temperature is set so as to provide a temperature difference between a pair of flat upper and lower heating plates, and hot pressing is performed to manufacture a curved panel.

In a laminated panel, the core material is formed by bending a plate material extending in a direction perpendicular to the thickness direction of the panel, and the surface of the plate material arranged along the curvature direction of the panel is in contact with one face plate. This is achieved by forming the side length longer than the side in contact with the other face plate.

If the side that contacts one face plate is longer than the other side,
Only by sequentially arranging the plate materials in a direction perpendicular to the curvature direction, the end surfaces of the plate materials form approximately curved surfaces in a state where they are in surface contact with each other. Therefore, it is possible to easily construct a laminated panel having a curved surface only by bonding face plates to both surfaces of the core material with an adhesive or a brazing material. Further, the curvature of the panel can be arbitrarily set by changing the dimensional difference between the sides having different lengths of the plate material forming the core material.
