る。[Detailed Description of the Invention] The present invention is a composite structure that integrates an embossed thin metal sheet, particularly an asymmetrical thin metal sheet embossed with a mixture of large and small patterns, and a gypsum board as a core material. This invention relates to a board and its manufacturing method.

することがあつた。 Conventionally, for example, a composite board that integrates a thin metal sheet with a smooth surface and a gypsum board has been produced by forming several layers of adhesive between the back of the thin metal sheet and the base paper for the gypsum board, and then holding the two together for a certain period of time. The company was manufacturing integrated composite boards. However, because the specific heat and rigidity of the thin metal sheet and the gypsum board are different, deformation of the gypsum board often deforms the color steel plate, and the adhesive deteriorates due to the hygroscopicity of the gypsum board, causing peeling. It was hot. In addition, even though conventional adhesives have a strong adhesive force similar to that of a simple line contact, they are subject to intensive thermal deformation of the iron plate, etc., and may break.

法を提供するものである。 In order to eliminate such defects, the present invention impregnates the gypsum base paper on one side of the gypsum board with an adhesive, softens the surface layer of the gypsum board itself, and embosses the embossed surface of a thin metal plate with an uneven pattern. To provide a composite plate which is fixed to the entire contact surface of a thin metal plate and a gypsum board etc. by biting and is also mechanically held, and a method for manufacturing the same.

and a sheet layer 4 which is located between the thin metal plate 2 and contains an adhesive. To further explain, the thin metal plate 2 has a concavo-convex pattern 2a formed into an arbitrary shape by embossing, for example, a concavo-convex pattern 2a which is shown in a plan view as shown in FIG. It is. That is, in FIG. 3, both ends of the decorative surface 2b are bent vertically to form a side wall 2c, which is then horizontally bent inward again, and further vertically bent, with its tip extended horizontally to form a U-shaped holding portion 2d. This is a thin metal plate 2 in which a connecting groove 2e is formed. In addition, the gypsum board etc. 3 is a plate-like body whose main component is gypsum,
For example, it includes gypsum boards, foamed gypsum boards, and boards in which aggregates such as shirasu balloons and perlite particles are added to gypsum boards. Further, the sheet layer 4 is interposed between the gypsum board or the like 3 and at least the decorative surface 2b of the thin metal plate 2,
It contains an adhesive 5, which is one of the factors that strengthens the adhesion between the gypsum board or the like 3 and the thin metal plate 2. This sheet layer 4 is mainly made of asbestos paper, kraft paper, gypsum base paper, thin open-cell foam sheet (thickness 5 mm or less), etc., and contains an adhesive 5, and water or the adhesive 5 is attached to the gypsum board. This is to penetrate up to the surface layer 3a of 3. As the adhesive 5, a water-soluble adhesive mainly containing water, such as starch, CMC, or PVA, is used. This adhesive 5 not only adheres the sheet layer 4 and the thin metal plate 2, but also softens the surface layer 3a of the gypsum board 3 with water, as shown in FIG. The concave back surface 2b of the decorative surface 2b penetrates somewhat into the sheet layer 4 and the surface layer 3a and is fixed thereto. That is, the metal thin plate 2 and the gypsum board or the like 3 are joined together by the hardening of the adhesive 5 and by the anchoring effect caused by the biting of the back surface 2b' of the recess, thereby making the integration strong. Further, the gypsum board or the like 3 is held by the U-shaped holding portion 2d.

た。 Next, the manufacturing method will be explained in detail with reference to FIG. 5. A thin metal plate (thickness: 0.27 mm) 2 is now fed to a forming machine 20 and formed as shown in FIG. 6a. On the other hand, the gypsum board 3 is a gypsum board having gypsum base paper on both sides, and is stacked on a stock stand (not shown). And the surface layer 3 of plasterboard etc.
For example, starch paste 21 with a viscosity of 200 to 300 poise is applied to the gypsum base paper on the surface that will be in contact with the thin metal plate 2 by spraying (not shown) or using a roll coater 22. Place it as shown in Figure 6a. Thereafter, while pressing the center of the gypsum board 3 through the molding machine 23 as shown in FIG. 6b, the left and right sides of the board are bent horizontally toward the center using a trident. At the same time, bend the tip outward.
At this time, the surface of the gypsum board or the like 3 that is in contact with the back surface of the thin metal plate 2 is firmly stuck and held in a structure as shown in FIG. In this state, the gypsum board or the like 3 is fed to the drying oven 24, and the composite board 1 having the structure shown in FIG. 1 comes out from the outlet thereof. When this composite board 1 was taken out and cut, it was found that the uneven pattern 2a had penetrated into the gypsum base paper, which is the sheet layer 4, by about 1 to 2 mm.

Kg/mm2であつた。 Here, the composite board 1 according to the present invention and a conventional composite board with a gypsum board or the like 3 sandwiched therebetween were held vertically and their lower ends were hammered vertically against a concrete stand approximately 10 times. The width of the deviation at that time is approximately 10 cm with conventional composite boards.
In the composite board according to the present invention, the thickness was about 1 cm. This is considered to be because the uneven pattern 2a is embedded in the gypsum board or the like 3 and is held in a resilient state. In addition, the bending strength is 3
Assuming that the thickness is 12mm, the current value is 70Kg/ mm2 , and the conventional example is 50Kg/mm2.
It was Kg/ mm2 .
