Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is characterized in that a fiber-containing hardening plastic material is layered on a metal plate,
The present invention also relates to a method of manufacturing a composite panel having a curved surface.

Conventionally, when manufacturing a metal plate product with a curved surface, the product (A) is bent using a mechanical jig ('') (b), as shown in Figure 6.
A method is to gradually form a curved surface by shifting the parts between the two, or a method to gradually form a curved surface by passing through multiple o-ra (C) spaces several times as shown in Fig. 7. are being taken.

The conventional method described above requires complicated labor and a lot of time, and even after processing a curved surface, when reinforcing material (B) is provided on the back side as shown in Figure 8, all of these also apply to the curved surface. It had to be molded.

The present invention was proposed in order to solve these problems, and involves closely adhering a metal plate to the molding surface of a mold for molding a curved surface, and then using the metal plate as a formwork to inject fibers into the surface. The present invention relates to a method of manufacturing a composite panel having a curved surface, which is characterized by layering a hardenable plastic material.

In the present invention, as described above, the metal plate of the composite panel is brought into close contact with the molding surface of the mold for forming a curved surface, and the metal plate thus formed into the required curved surface is used as a formwork and fibers are inserted into the surface of the metal plate. A composite panel is manufactured by layering a curable substance and integrating the curable substance and the metal plate.

As described above, according to the present invention, it is possible to accurately and easily manufacture a composite panel having a cylindrical structure and a curved surface, thereby reducing manufacturing time and manufacturing costs.

The present invention will be described below with reference to the illustrated embodiments.

(1) is a mold for molding a curved surface, and fastening screws (2) are set up at predetermined intervals from both sides of the molding surface (1α).

(h) is a metal plate of a composite panel having a curved surface, which is dropped into the mold (1) in a natural state. In this case, if the metal plate (3) is a thin plate, the molding surface (1
a), but it is difficult to adapt to relatively thick materials.

In this case, both ends of the metal plate (3) are held down by the holding plate (4), and the screw rod (2) is inserted into the bolt hole (4α) of the holding plate (4) and the nut (5) is screwed. By fastening the metal plate (3), the metal plate (3) is adapted to the molding surface (1a) of the molding die (1).

In this way, the metal plate (3) is completely adapted to the molding surface (1α) of the curved surface molding mold (1).
) is coated with an elastic adhesive, and a foam sheet material with a large number of perforations or a porous surface is bonded via the adhesive, and after drying, the foam sheet material is bonded to the metal. The plate (2) is used as a formwork and a fiber-containing hardening plastic material (6) such as glass fiber-containing concrete is sprayed onto the surface thereof.

The method of layering this curable plastic material (6) is described in detail in Japanese Patent Application No. 59-87709, which was filed by the present inventor.

Alternatively, an elastic adhesive may be applied to the surface of the metal plate (3), and spherical foam chips may be spread on the adhesive layer. (3) is used as a formwork, and a fiber-containing hardening plastic material (6) such as glass fiber-containing concrete is sprayed onto its surface. The method of layering this curable plastic material (6) is described in detail in Japanese Patent Application No. 1987-87710, which was invented by the present inventor.

After curing, the fiber-containing curable material (6) is molded to produce a composite panel having a curved surface.

In the composite panel manufactured by Koriyo-5, the fiber-containing curable plastic material layered on the surface of the metal plate becomes a reinforcing material for the metal plate after hardening, so there is no need to reinforce the surface of the metal plate.
Also, unlike pillars, it will not dent or be damaged even if the surface is subjected to impact.

Note that FIG. 3 shows a cylindrical column formed by combining a pair of semi-cylindrical bodies manufactured by the above method, and FIGS. 4 and 5 show the protruding corner and This is a composite panel with curved surfaces at the inside corners.

Although the present invention has been described above with reference to embodiments, the present invention is, of course, not limited to such embodiments, and can be modified in various ways without departing from the spirit of the present invention. .
