The present invention will be explained in detail below with reference to examples. The facing outer skins 1 and 2 are both metal plates, and the outer skins 1 and 2 are metal plates.
A panel body 4 is constructed by integrally filling the space with a hard foamed synthetic resin 3. A shutter 9 is constructed by vertically connecting a plurality of panel bodies 4 with hinges 8. To fix the hinge 8 to the panel body 4, the hinge plate portion 10 is overlapped with the outer skin 1 made of a metal plate located on one side of the panel element 4, and is fixed to the outer skin 1 with a fixing tool 11. In this case, in the embodiment shown in FIG.
A fixing tool 11 is inserted from the hinge plate part 10 while being in contact with the outer skin 1, and is fixed to the band plate 12 via the outer skin 1. A fitting protrusion 5 is protruded from one of the opposing end surfaces of the panel bodies 4 that are vertically adjacent to each other.
A fitting recess 6 that can be freely fitted with the fitting protrusion 5 is provided on the other side. Here, at least one of the fitting protrusion 5 and the fitting recess 6 is provided with an elastic airtight material 7, and in the embodiment shown in the drawings, the fitting recess 6
An airtight material 7 is provided at. Rollers 13 are attached to both left and right ends of the panel body 4. In the embodiment shown in FIG. 6, a roller support portion 10a is provided on one hinge plate portion 10 of the hinge 8 located at the end, and a roller 13 is rotatably supported on this support portion 10a. Vertical rails 14 are provided on both sides of the opening of the building, and horizontal rails 15 are connected from the upper ends of the vertical rails 14 under the ceiling on the indoor side. In other words, the vertical rail 14
and the horizontal rail 15 constitute a substantially inverted L-shaped rail. The shutter 9 has each roller 13 fitted into the left and right rails so that it can run freely. When the shutter 9 is positioned on the vertical rail 14, the opening of the building is closed, and when the shutter 9 is moved and positioned on the horizontal rail, it closes the opening of the building. The opening is designed to be open. The shutter 9 is opened and closed by an opening and closing means 16. FIG. 3 shows an example of the opening/closing means 16. In this embodiment, the lower end of the wire 18 wound around the pulley 17 is connected to the lowermost panel element 4, and the pulley 17 is rotated by the motor 21 to move it along the shutter 9 rail. It's summery. In FIG. 3, reference numeral 19 is a coil spring wound around the shaft 20 of the pulley 17, and this coil spring 19 applies a spring force to the shaft 20 in the direction of pulling up and opening the shutter 9. This serves to reduce the force required to pull up the shutter 9 due to the rotation of the motor 21. In this embodiment, a pulley 17, a wire 18, a coil spring 19, and a shaft 2
0, an opening/closing means 16 is constituted by a motor 21 and the like. In FIG. 4, a rail body 22 is provided approximately parallel to the horizontal rail 15, and a motor 2 is mounted on the rail body 22.
A traveling body 23 that travels by the drive of the shutter 9 is provided, and the traveling body 23 and the upper end of the shutter 9 are connected to the connecting body 2.
6 and are rotatably connected to each other, and the shutter 9 is opened and closed as the traveling body 23 travels. Also in this embodiment, the coil spring 25 wound around the shaft 24 serves to reduce the pulling force when the shutter 9 is pulled up.
However, when the shutter 9 is moved from the horizontal rail 15 to the vertical rail 14 and the opening of the building is closed,
The fitting protrusion 5 and the fitting recess 6 fit together as shown by the solid lines in FIGS. 1 and 2, and this fitting compresses the airtight material 7, improving the heat insulation properties of the connection between the panel bodies 4. Airtightness is ensured. On the other hand, when opening an opening in a building, the shutter 9 is pulled up and moved from the vertical rail 14 to the horizontal rail 15. In this case, vertical rail 1
4 to the horizontal rail 15, and from the horizontal rail 15 to the vertical rail 14, the panel bodies 4 are connected to each other by the hinge 8.
It is something that moves by folding in parts as shown in the imaginary lines in Figure 2.

[Effects of the invention] As described above, in the present invention, a plurality of panel bodies filled with hard foamed synthetic resin between two metal outer skins are connected in a vertically foldable manner. , the panel body itself has heat insulation and airtightness, and in addition, a fitting recess is formed on the lower end face of the upper panel body, and a fitting protrusion is formed on the upper end face of the lower panel body. The fitting recess is filled with an elastic airtight material, and the fitting projections are formed by protruding the front and back metal skins at intervals in the thickness direction of the panel body. Therefore, when the panel bodies are butted vertically to close the shutter, the fitting protrusion enters the fitting recess and compresses the airtight material in the fitting recess, and the fitting protrusion also seals the front and back sides. A pair of biting protrusions formed by protruding the metal outer skin bite into the airtight material, and there is an advantage that sufficient airtightness and watertightness can be obtained when the shutter is closed. In other words, by effectively utilizing the metal skins on the front and back, these are used as biting protrusions, and the pair of biting protrusions spaced apart on the front and back sufficiently bite into the elastic airtight material.
It is characterized by its ability to provide sufficient airtightness and watertightness.

In addition, the edge piece of the outer skin on the center side in the thickness direction of the panel body on the side of the biting protrusion and the edge piece of the outer skin on the side of the fitting recess facing the biting protrusion are deep and deep in the hard foam synthetic resin. Since the biting protrusions are embedded substantially parallel to each other at approximately equal intervals, when the biting protrusions bite into the airtight material, the biting protrusions press against the opposing edge piece of the outer skin through the airtight material, and in such a case, The edge piece of the outer skin on the side of the biting protrusion and the edge piece of the outer skin facing the biting protrusion are both deeply embedded in the hard foamed synthetic resin at approximately equal intervals and approximately parallel to each other, and the positioning of these edge pieces is It has the advantage that it can be maintained with sufficient strength and that the airtightness can be greatly improved when the protrusion bites into the airtight material.
