PROBLEM TO BE SOLVED: To prevent occurrence of abnormalities on a cloth face or a painted face after finish by connecting a plurality of backing plates by a thin sheet member provided with sufficient toughness and flexibility. SOLUTION: Two backing plates 1a, 1b having appropriate width and length butted against each other and a V-shaped valley forming 90 degrees at the interior angle is formed between the butting end faces 13. Further, a thin sheet material 2 is stuck to a protection paper at the back face of the V-shaped valley to integrally connect the both. When the V-shaped part is folded to bring the mutual end faces to contact with each other, since the backing plates 1a, 1b of the backing plates are bent at 90 degrees, when these are fixed with nails as they are at positions spaced apart from a recessed corner or a projected corner in furring strips C or studs D connected to a column B. A backing plates for the recessed corner or a projected corner can be formed. Further, as the backing plates 1 having different faces from each other are connected by the thin sheet material 2, the backing plates is integrally constituted and hence, a strong action on the connection part does not work even in vibration of the building and even when a slight external force acts thereon, no abnormality arises in the cloth connected by the thin sheet material 2.
