Can also be facilitated.

  As shown in FIG. 2, in the heat insulating composite panel 14 constituting the side wall portion 3, the upper edge of the outer plate 7 extends substantially by the thickness of the heat insulating composite panel 14 constituting the ceiling portion 4. The heat insulating composite panel 14 that constitutes the ceiling portion 4 has a side wall portion 3 in which the lower surface of the edge portion is overlapped with the upper end surface of the heat insulating composite panel 14 that constitutes the side wall portion 3 and the side end surface extends upward. The heat insulating composite panel 14 is abutted against the inner surface of the outer plate 7.

For example, polystyrene foam, polyethylene foam, polyurethane foam and the like can be used, and polystyrene foam is particularly preferable. Moreover, although it may be an extrusion molded product or a bead foam molded product, an extruded foam molded product is preferable because it is excellent in strength and easily obtains a single piece having a large joint size. The outer plate 7 and the inner plate 8 can be made of, for example, an aluminum plate, an iron plate, a fiber reinforced plastic (FRP) plate, or the like.

The outer plate mounting screw 12 can be passed through the outer base material 10 or the inner plate mounting screw 13 can be passed through the inner base material 11, but in order to improve the assembly workability, the outer plate It is preferable to drive the mounting screw 12 and the inner plate mounting screw 13 through the gap.

  Although the outer plate mounting screw 12 and the inner plate mounting screw 13 are usually made of metal, it is preferable that at least the head is covered with a synthetic resin in order to suppress these heat insulation defects due to heat conduction. In order to improve waterproofness, it is preferable that the places where the outer plate mounting screw 12 and the inner plate mounting screw 13 are driven are subjected to waterproof sealing treatment. In addition, an adhesive can be used in combination with the attachment of the outer plate 7 and the inner plate 8 in order to prevent these partial floats.

FIG. Further, in this example, the inner plate mounting screw 13 is long and the outer plate mounting screw 12 is short. However, this is reversed, and the outer plate mounting screw 12 penetrates the outer base material 10 and the heat insulating plate 9 to the inner side. Alternatively, the inner plate mounting screw 13 may be directly driven into the inner base material 11 by driving in the middle of the thickness of the base material 11.

  FIG. 8 is a cross-sectional view showing a fourth example of the heat insulating composite panel used in the storage of the present invention. The same reference numerals as those in FIGS. 1 to 6 denote the same members or parts.

  The heat insulating composite panel 14 of this example is the same as the third example of the heat insulating composite panel except that a backing material 18 is provided between the outer plate 7 and the outer base material 10. The backing material 18 is formed of a plywood such as a veneer plate, for example, and is attached by an outer plate mounting screw 12 that penetrates the backing material 18 and is driven into the outer base material 10.
