2. Description of the Related Art As a method for finishing a constructed wall in a building such as a house, a method is known in which a necessary number of decorative gypsum boards having a decorative sheet attached to the surface thereof are attached to the wall portion for finishing.

In this case, as the decorative gypsum board, a decorative sheet having a fixed width adhered to the surface in advance, and further, both end portions of the decorative sheet are wound and fixed on the back surface of the gypsum board are used. It is delivered to the site. At the site, the wall finish is completed simply by attaching the decorative gypsum board to the surface of the constructed wall.

However, since the decorative gypsum board has a constant width, it may be necessary to make adjustments in a portion where the dimensions of the decorative gypsum board and the wall to be attached do not match. For example, a small wall on the door of the unit bath. Since the finished product is loaded into the unit bath and only the installation is performed on site, the standard of the unit bath may not match the width dimension of the decorative plaster board.

In such a case, the decorative gypsum board is cut to have a required width so that the width is reduced and the dimensions are adjusted. As shown in FIG. 4, the decorative gypsum board 10a is subjected to the width reduction. Since the cut edge of the decorative sheet 20 is exposed on the cut surface, the joiner 40 is attached to the joint portion between the width-decreased decorative gypsum board 10a and the adjacent fixed-width decorative gypsum board 10b.

However, if the joiner 40 is attached only to the joint between the cut surface side of the width-filled decorative gypsum board 10a and the adjacent fixed-width decorative gypsum board 10b, the appearance is unbalanced. Therefore, the joiner 40 is also attached to the joining portion on the other side (FIG. 5). As a result, there is a problem that the number of parts is increased and the cost is increased in addition to the labor.

The present invention is intended to solve the above-mentioned problems, and it is possible to easily perform width filling of a decorative gypsum board having a constant width.
(EN) Provided is a method for filling the width of a decorative gypsum board and a decorative gypsum board which does not require any other part for mounting on a wall and can be performed in the same manner as a decorative gypsum board without width filling.

[0008]

In order to achieve the above object, the first invention is for wall finishing in which both side ends of a decorative sheet attached to the surface of a gypsum board are wound and fixed on the back surface of the gypsum board. A method for filling the width of a fixed-width decorative gypsum board, in which a cut is made at the back cutting position of the decorative gypsum board, the gypsum board is cut at the cut position, and the gypsum board removed from the cut portion is made up. Peel off from the sheet, cut the decorative sheet of the gypsum board removed part at least at a position longer than the thickness of the gypsum board from the cut surface, wrap the edge of the decorative sheet on the back surface of the gypsum board and fix it, and perform width packing. Is characterized by.

A second aspect of the present invention is a decorative gypsum board with a fixed width for wall finishing, in which both side edges of a decorative sheet attached to the surface of the gypsum board are wound and fixed on the back surface of the gypsum board.
It is characterized in that cut lines for width reduction are formed in advance at least near the back surface side of the decorative gypsum board.

[0010]

In the width-filling method according to the first aspect of the present invention, since the cut surface of the decorative gypsum board after width-filling is not exposed, no other component is required for mounting on the wall.

According to the second aspect of the present invention, since the cut is provided in advance at the cutting position, the width of the decorative gypsum board can be more easily filled.
