To maintain water proofing performance and prevent cracking in a light cellular concrete plate corresponding to a joint around decorative plates due to temperature change and wind pressure by laminating the light cellular concrete plate and a plurality of large decorative plates to be relatively movable in a plane direction via a water-proof layer.
For a light cellular concrete (ALC) combined panel A, a plurality of large decorative plates 1 formed from large ceramic plates such as tiles having an area of 0.1 m2 or more each on the surface side are laminated on a ALC plate 2 via a water-proof layer 3 so that the ALC plate 2 and the large decorative plates 1 are relatively movable in a plane direction with the water- proof layer 3. The water-proof layer 3 includes a water-proof material layer 4 such as a water-proof paint layer showing water proofing performance and a stress relaxing layer 5 such as a sponge capable of relatively moving the large decorative plates 1 and the ALC plate 2 in the plane direction. Latching pawls 18, 19 for a stopper fitting 6 are latched to latched holes 1a in the large decorative plates 1 and an anchor portion 9 of the stopper fitting 6 is locked to a fixing groove 7 formed in the ALC plate 2 for connection.
