In this invention, a synthetic resin foam that functions as an adhesive and a heat insulator is discharged between a plastic foam plate and the plate material in a raw state, and is reacted and foamed.Moreover, a stopper is integrated between the plastic foam plate and the synthetic resin foam. This invention relates to an interposed composite plate. BACKGROUND ART Composite plates in which a foamable synthetic resin raw material is discharged between two members and are fixed together using the self-adhesive property during foaming have been known. However, when one of the two components is brittle, such as phenol foam, and has a surface with powder scattered on it, when bonding it together with the other component to form a synthetic resin foam, adhesive is used. The cohesive failure of the phenol foam was greater than the strength of the synthetic resin foam, and the phenol foam had the disadvantage of peeling off from the synthetic resin foam. Furthermore, since phenol foam utilizes an acid curing agent when forming the foam, it has the disadvantage of corroding the metal when it comes into direct contact with a metal plate. Furthermore, phenol foam has a disadvantage in that it is weak in mechanical strength, especially in bending, and easily cracks due to external force. On the other hand, due to fire prevention regulations, there is an increasing demand for phenol foam, which has characteristics such as low smoke generation and the ability to carbonize without changing its external shape even under high heat. In addition, there is a demand for composites of other materials with resins that cannot be molded under normal conditions, but this has not been put to practical use due to adhesive strength. In order to meet these demands, the present invention involves implanting a large number of fasteners from one surface of a molded foam board toward the back, and improving the surface area of the implanted fasteners and the physical bonding reinforcement structure. The aim is to strengthen the integration of the synthetic resin foam made from foamed raw materials with self-adhesive properties and the foam board, to make the foam board elastic, and to eliminate direct contact with other parts. This paper proposes a composite board that has improved fire resistance, heat insulation, and strength, and has a structure that prevents peeling between each member. The composite plate according to the present invention will be explained in detail below using the drawings. FIG. 1 is a perspective view showing a typical example of the composite board, in which 1 is a plastic foam board (hereinafter simply referred to as a foam board), 2 is a stopper,
3 is a plate material, and 4 is a synthetic resin foam for fixing the foam plate 1 and the plate material 3 together. Further clarifying, the form plate 1 is formed into a rectangle as shown in FIG. 2, or a square (not shown),
Moreover, the plate thickness t1 is 5~50mm, the density is 20~150Kg/ m3 ,
It is molded to have a width W of 150 to 900 mm and a length L of approximately 600 to 3000 mm. In addition, the stopper 2 is shown in Fig. 3a~
A shape as shown in f is planted from one surface of the foam board 1 toward the back surface, with one end protruding from the surface of the foam board 1 by Δ.
The above-mentioned shape of the stopper 2 is a stopper with flanges 2b provided at both ends of a column 2a as shown in figure a;
Figure b shows a stopper with a flange 2c formed at the boundary between the foam plate 1 and the synthetic resin foam 4, and figure c shows the column 2.
a stopper having a flange 2b formed only at one end of a;
Figure d is a cylindrical stopper, figure e is a cylindrical stopper,
Figure f shows a rectangular wave shaped stop. The implantation state of the stopper 2 can be determined by either inserting the stopper 2 into the form board 1 when it is formed, or into the formed form board 1, as shown in FIGS. 4a to 4e. That's it. That is, Figures a to d show that the stopper 2 is provided when forming the foam board 1, and then the raw material for the form board 1 is foamed and hardened, and Figure e shows that the stopper 2 is inserted and the form board is formed. This is a case where 1 and the stopper 2 are integrated. The board material 3 functions as a decorative board, a surface material, and a shape material, and is, for example, a slate board, a gypsum board, other ceramic boards, a metal board (A, Cu, Fe), or a flat board of FIG. It was molded as shown in q. Furthermore, the synthetic resin foam 4 is interposed integrally between the foam plate 1 and the plate material 3, and mainly functions as an adhesive, a heat insulating material, a waterproof material, a moisture proof material, a cushion material, and a bulking material. . Specific examples include hard polyurethane foam, polyisocyanurate foam, urethane-modified phenol foam, and the like. Further, the synthetic resin foam 4 is discharged as a raw material between the foam plate 1 and the plate material 3, and the foam is formed at the same time as the two members are bonded together by self-adhesive properties during reaction and foaming. The plate thickness t2 is 3 to 20 mm, and the density is 20 to 100 Kg/m. Next, form board 1, synthetic resin foam 4 and board material 3
The adhesive strength between the two will be explained. Therefore, the foam board 1 is a resol type phenol foam board with a density of 40 kg/m 3 , t 1 = 15 mm, W = L = 40
The plate material 3 is a 0.27 mm color steel plate with a service coat of epoxy resin on the back side, and the synthetic resin foam 4 after reaction foaming is polyisocyanurate foam with a density of 30 Kg/m 3 and a thickness of 30 kg/m 3 . t 2 = 10 mm, the stop 2 has the shape shown in Figure 3 a, the height is 15 mm, the diameter of the flange is 10 mm, and the main column 2
It is made of polyester resin and has a diameter of 5 mmφ. In addition, the number of arrangement is 5 to 10 pieces/10 cm, which ranks second . In addition, as a comparative example, a form board with the dimensions of the form board 1 but without the fasteners 2 installed,
The same materials as above were used for the plate material 3 and the synthetic resin foam 4. In addition, the composite plate is made by discharging the raw material of the synthetic resin foam 4 onto the foam plate 1 and the plate material 3, and causing a reaction.
It is foamed and integrated. Therefore, the adhesive strength of the composite board was measured according to JIS-A-1613 (tensile test). The results are shown in the table below.

[Table] ○A is because the form plate 1 undergoes cohesive failure. In addition, thermal insulation, water absorption resistance, and bending tests were conducted on each of the above samples, and the properties of the composite plate of the example were about 8 to 15% superior to those of the comparative example. As mentioned above, according to the composite board according to the present invention,
Because the brittle foam board or the molded foam board and the board material were bonded together using self-adhesive properties during foam formation, and a stopper was integrally interposed between both members, each member did not peel off from the bonded part. There is a characteristic that there is nothing to do. In addition, even materials that have a negative impact on other components, such as phenol foam plates, can be combined with metal plates by interposing synthetic resin foam, and the composite plate has excellent fire resistance and strength. There is.
