いた。2. Description of the Related Art Conventionally, all plates including composite plates are
It was a conventional technique to provide a seat for accommodating the heads of nails, screws, etc. on the surface of the composite plate or plate when attaching with fasteners (hereinafter referred to as nails, screws, etc.) such as screws and bolts. However, in the case of a composite board, it is structurally difficult to provide a seat on the surface because the surface layer is thin, and it is not economical to process the seat on the surface layer. It was often used without. In that case, as shown in FIG. 6, the heads 9 such as nails and screws for attaching the composite plate are used while protruding from the surface of the composite plate, or the lower layer of the composite plate is soft like foam resin. In the case, use a hammer or screwdriver to remove the nails and screws, and
As described above, the head 9 such as a nail or a screw has been used by being driven in or tightened until it becomes flush with the surface of the composite plate.

すいという欠点があった。Conventionally, as shown in FIG. 6, attachment of a conventional composite plate is often performed with a head 9 such as a nail or a screw protruding from the upper surface of the surface layer. In this case, the heads 9 such as nails and screws are exposed on the surface of the composite plate after the construction, and there is an aesthetic problem. There was a problem that it was necessary to further install wall cloth, wallpaper, interior finishing board, carpet, flooring (hereinafter referred to as "finishing material") on the upper layer of the board. Furthermore, even when this finishing material is applied, since there are irregularities, there are drawbacks that it is difficult to make the surface of the finishing material completely flat, and problems such as impairing adhesion are likely to occur.

た。When the lower layer of the composite plate is a little soft, when the nail is struck or the screw is strongly tightened, the surface layer locally appears at the lower portion of the head 9 such as the nail or screw as shown in FIG. It deforms and nails and screws bite into it. Therefore, if the nails / screws are bitten until the upper surfaces of the heads 9 such as the nails / screws exactly match the upper surfaces of the surface layers, the surface of the composite plate after the construction will have no protrusion of the nails / screws or the like. It is almost flat and almost flat. This kind of construction has also been carried out quite widely.
