いのが現状である。By the way, the outer surface of the metal plate of the heat insulating panel is exposed to the outside air, and the plating is effectively used to maintain durability and corrosion resistance. However, the inner surface of the metal plate is made of urethane resin. It is closely adhered and protected by a resin foam such as that. Therefore, the plating on the inner surface does not contribute to the durability and the like, and the cost is increased, but it is not utilized effectively.

ある。According to a first aspect of the present invention, there is provided a heat insulating panel in which a heat insulating material 2 is filled between two metal plates 1, and the thickness of the outer plating layer 3 of the metal plate 1 is set to the inner surface. The thickness of the side plating layer 4 is larger than that of the side plating layer 4.
The invention is a heat insulating panel in which a heat insulating material 2 is lined on the inner surface of a metal plate 1, and the thickness of the outer plating layer 3 of the metal plate 1 is made larger than the thickness of the inner plating layer 4. The above problems are solved by these configurations.

The metal plate 1 in the present invention is not limited to a plated steel plate, and may be a coated steel plate obtained by baking and coating a plated steel plate, a stainless steel plate, an aluminum plate, or the like. The plating is not limited to zinc plating, aluminum-zinc alloy plating, tin plating, tin alloy plating, and may be adopted depending on the application.

は、既存のラインでは生産性が低下してしまう。In the plating layer of the metal plate 1, the thickness t 1 of the outer plating layer 3 is larger than the thickness t 2 of the inner plating layer 4. For example, in the hot-dip galvanized steel sheet, the outer surface side plating layer 3 has the adhesion amount symbol Z18 defined by the JIS standard, while the inner surface side plating layer 4 has the adhesion symbol Z06 defined by the minimum required JIS standard. As a result, the amount of zinc used can be reduced by about 60 g per 1 m 2 of plated steel sheet,
It is economical. In addition, when used in harsh outdoor air where high durability and corrosion resistance are required, saved zinc is stacked on the outer plating layer 3 to ensure durability and corrosion resistance even if the total amount of zinc is the same. An excellent heat insulating panel can be manufactured. The ratio of the plating adhesion amount forming the outer surface side plating layer 3 and the inner surface side plating layer 4 is not particularly limited, but the upper limit of the plating adhesion amount forming the outer surface side plating layer 3 is 90 to 14.
It is preferably in the range of 0 g / m 2 . If it exceeds this range, workability such as bending property may be deteriorated. On the other hand, the amount of plating applied to form the inner plating layer 4 is preferably in the range of 30 to 45 g / m 2 . 45
If g / m 2 is exceeded, economic effects such as cost reduction cannot be expected, while 30 g / m 2 is the minimum plating amount in a normal plating method, and the adhesion amount of plating smaller than this is the existing amount. In that line, productivity will decrease.

とができるものである。According to the present invention, the thickness of the outer plating layer of the metal plate is made larger than the thickness of the inner plating layer. Therefore, the outer plating layer should have the same thickness as the conventional product. As a result, the same durability and corrosion resistance as conventional products can be ensured, and since the overall plating adhesion amount is small, it is excellent in workability and inexpensive, and the smaller inner plating layer reduces the outer surface. By adding extra to the side plating layer, the total amount of plating applied is the same and the workability and cost are the same as the conventional product, but the thickness of the outer plating layer can be increased and durability and corrosion resistance can be improved. It is possible.
