BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a perspective view showing a molded plate for an elevator used on a cab wall of an elevator as a first embodiment, FIG.
FIG. 2 is an enlarged sectional view showing a part of FIG. 1. In the figure, an elevator molded plate 1 is composed of a composite plate main body 2 and an aluminum thin plate 3 which is a nonflammable metal thin plate covering both surfaces of the composite plate main body 2. The composite plate body 2 is composed of a stainless steel powder 4 which is a non-combustible metal powder, a melamine resin 5 which is a thermosetting synthetic resin, and a ceramic powder 6.

Next, an example of a method for manufacturing the above-mentioned elevator molded plate 1 will be described. First, a stainless steel powder 4, a melamine resin 5, and a ceramic powder 6 are put into a container 7 as shown in FIG. 3 and mixed. At this time, the distribution amount (volume ratio) of each material is about 80 to 90% for the stainless steel powder 4 and the ceramic powder 6, and about 10 to 20% of the whole for the melamine resin 5. FIG. 4 shows an enlarged cross section of the mixed material 8 thus produced. In this state, the melamine resin 5 is also a powder.

Next, as shown in FIG.
The mixed material 8 is arranged between two thin aluminum plates 3 having a thickness of approximately equal thickness. And
As shown in FIG. 6, the heater 9 is set between the press table 10 and the press plate 11, and pressurization and low-temperature heating are performed. As a result, as shown in FIG. 7, a rectangular composite flat plate 12 is completed as an intermediate.

[0010] Thereafter, as shown in FIGS. 8 and 9, a composite flat plate is formed between the lower die 13 and the upper die 14 of the product having the built-in heater 9.
Set 12 and pressurize and heat at high temperature. Thereby, the molded plate 1 for an elevator having the shape as shown in FIG.
Is molded. Thereafter, plating or alumite finishing is appropriately performed on the surface to prevent coloring of the design and oxidation prevention.
Further, as other surface processing, a hairline processing or a mirror surface processing by a buff is performed as necessary before the alumite finish. Such surface processing can be performed on the aluminum thin plate 3 in advance.

For the elevator manufactured in this way
Since the entire surface of the formed plate 1 is covered with the aluminum thin plate 3 and the inside is made of a nonflammable material, the formed plate 1 is excellent in heat resistance and fire resistance. Also, since the melamine resin 5 is used as a matrix, the moldability is good.
Furthermore, since the stainless steel powder 4 is a powder, the composite plate main body 2 has good thermal dimensional stability, and therefore has good thermal dimensional stability as a whole. Furthermore, since the composite plate main body 2 contains a large amount of stainless steel powder 4 and the surface of the composite plate main body 2 is covered with the aluminum thin plate 3, it has excellent rigidity, vibration damping properties, mechanical properties and sound insulation. In addition, since the composite plate body 2 is molded from the powder mixed material 8, there is no waste, and waste products can be used (resource recycling), which is excellent in economic efficiency.

Further, in the above embodiment, since the ceramic powder 6 is mixed in the composite plate body 2, the heat resistance and fire resistance can be further improved, and the overall weight can be reduced. Further, in the above embodiment, since the composite flat plate 12 as an intermediate is manufactured by low-temperature heating and pressing and then formed into a product shape, it is easy to process, and transport and storage at an intermediate stage are easy.

Next, the second to fourth embodiments of the present invention are shown in the following table. The manufacturing process is the same as in the first embodiment.

[0014]

[Table 1]

[0015] Incidentally, unsaturated retardant metal powder and synthetic resin may be a material other than the above-described embodiments, and various modifications are possible combinations and allocations like. However, from the viewpoint of heat resistance and fire resistance, the distribution amount of the synthetic resin in the mixed material is preferably 20% or less, and is suitably about 10%. Further, the synthetic resin is not limited to the thermosetting resin, but may be a thermoplastic resin as long as the temperature at which the fluidized state is high is high. Furthermore, the thin plate is not limited to the aluminum thin plate 3 but may be another one as long as it is made of a nonflammable metal.

[0016]

As described above, the molded plate for an elevator according to the first aspect of the present invention forms a composite plate main body from a mixed material having ceramic powder, non-combustible metal powder and synthetic resin. Since both sides of the main body are covered with a nonflammable metal sheet, workability, rigidity, thermal dimensional stability, vibration damping, sound insulation, mechanical properties and economics are not impaired.
It is possible to improve the heat resistance and fire resistance, especially heat and
Excellent structural material for elevators that require fire resistance
Can be used as Moreover, since the mixed material has also been used a ceramic powder, it can reduce the weight of the whole while further improving the heat resistance and fire resistance, thereby Jer
The weight of the beta basket can be reduced, and thus the basket
It is possible to reduce the size of the driving source required for raising and lowering the device. Also, since both surfaces of the composite plate main body are covered with a thin plate thinner than the composite plate main body, molding into a product shape is easy. Further, the molded plate for an elevator of the invention according to claim 2
Has plating on the surface of a thin metal plate,
And the environmental resistance can be improved. Claims
