る。 The gist of this invention is that two flexible thin plates impermeable to an uncured resin composition or a resin melt are arranged facing each other, their peripheral edges are hermetically closed, and the two plates are fixed. A foamed resin composite plate is formed by injecting a foamable resin composition between the thin plates, foaming and solidifying it, and the thin plates are tensilely deformed or plastically deformed by the foaming pressure, and the peripheral edge is fixed to a rigid structure. The foamed resin composite board is characterized by:

揮する。 The foamed resin composite board, which is formed by foaming and solidifying a foamable resin composition injected between two thin sheets with their peripheral edges closed airtight, has a shell structure in which the internal pressure and the tension of the thin sheets on both surfaces are balanced. It exhibits high rigidity and bending strength.

高いこの発明の複合板が得られる。 If the foamed resin inside has relatively high compressive strength and dimensional stability, such as hard polyurethane, the thin plate tension and internal pressure will be balanced and the shape and dimensions will be stable even if the fixed frame is removed, and the composite plate can be treated as a single unit. You can also do it. However, by fixing the peripheral portion to a rigid structure, it is possible to obtain a composite plate of the present invention that has high rigidity, high bending strength, and is highly practical.

A foamable rigid urethane resin composition comprising an isocyanate, a polyol, a blowing agent catalyst, a stabilizer, etc. is injected between the thin plates 2 and 2 thus fixed. Since the peripheral edges of the two thin plates 2, 2 are fixed, the foaming pressure of the foamable resin composition is the same as that of the two thin plates 2, 2.
2 acts as a tension force that expands it, causing it to be elastically or plastically deformed into a spherical shell shape. The foamed urethane resin 4 that has been foamed and solidified inside is filled between the two spherical shell-shaped thin plates 2, 2, and is also filled between the thin plates 2, 2 at the interface.
The thin plates 2, 2 and the foamed urethane resin 4 are bonded together to form a foamed resin composite board. By fixing the peripheral edges of the two thin plates 2, 2 of this composite plate to the rigid structure of the welded portion 5 as shown in FIG. 2, the foamed resin composite plate A of the present invention is obtained.

合板Ａとなし屋根が構築される。 FIG. 5 shows an embodiment in which the roof of the Oharama frame is constructed using the foamed resin composite plate A formed along the upper surface of the truss 6. To construct this roof, two thin rigid plates 2, square or regular hexagonal, etc.
2 are piled up and their peripheral edges are fixed airtight by welding or the like, and their peripheral edges are fixed to a fixing frame 1 that matches the dimensions of the thin plate 2 stretched over the truss 6. Lay it out on the body. Subsequently, a foamable resin composition is injected between each of the thin plates 2, 2, and is foamed and solidified. At the same time, tension is applied to the two thin plates by the foaming pressure, and the two thin plates are deformed into a spherical shell shape to form a foamed resin composite plate A. A town roof is constructed.

あつてもよい。 In constructing this roof, the peripheral edges of the two thin rigid plates 2, 2 are airtightly fixed in advance by welding or the like, fixed to the fixed frame 1, and foamed resin is applied between the thin plates 2, 2. A material may be injected and foamed and solidified to transform it into a spherical shell shape to form a foamed resin composite board A whose peripheral edge is fixed by the fixing frame 1, and this may be placed and fixed on the truss 6. For mounting and fixing, continuous support or point support may be used.

称な形とすることもできる。 This foamed resin composite board is not limited to those described above. For example, as shown in Fig. 6, when forming a composite plate, a restrictor piece 7 is attached to the center of the composite plate to connect two thin plates 2, 2, thereby limiting the spacing between the thin plates 2, 2 and deforming them. It may be.
Further, by using two thin plates having different elastic moduli or proportional limit elastic moduli, it is also possible to make the deformation of the front and back sides asymmetrical.

The foaming pressure is selected depending on the elastic modulus of the thin plate used, the proportional limit elastic modulus, or the required degree of deformation. The foaming pressure can be adjusted by using a foaming agent such as Freon or by adjusting the injection amount of the foamable resin composition. Urethane-based compositions are easy to handle, can be used at relatively high foaming pressures, and can form hard foamed resins with good adhesion to thin plates, so they are suitable for use as foamed resins for composite boards. be.

形成できるので施工面でも能率化が達成できる。 This invention has the above structure, and this foamed resin composite plate is deformed by the application of tension in the direction in which the two opposing thin plates are pushed and spread, forming a shell structure that balances the internal pressure of the foamed resin injected inside, and the peripheral edge is fixed to a rigid structure. Therefore, even if the thin plate has low rigidity, by injecting hard foamed resin, the composite plate will exhibit high rigidity and bending strength. Furthermore, since it is made of thin plates and foamed resin, it is lightweight and has excellent heat insulation performance. For this reason, it is suitable as a panel for the roof of an Oharima frame, etc., and can be made into a composite board at the construction site or while attached to a frame, making it possible to achieve efficiency in construction.
