DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. At both ends of the upper and lower metal shells 1 and 2 sent out by the feeding device, a fitting convex outer shell portion 4a and a fitting concave outer skin portion 5a are formed by roll forming, and these two metal shells 1 and 2 are formed. A rock wool material 3a and a calcium silicate 3b as heat insulating materials 3 are loaded between the two. The calcium silicate 3b has high fire resistance and high mechanical strength. The calcium silicate 3b is loaded on the fitting convex portion outer skin portion 4a and the fitting concave portion outer skin portion 5a to improve the fire resistance and mechanical strength of the fitting convex portion 4 and the fitting concave portion 5. Is increasing. The two metal shells 1 and 2 have a slight gap between the fitting projection 4 and the fitting recess 5 so as to avoid heat transfer between the two metal shells 1 and 2. .

A nailing portion 7 is formed on the side of the fitting recess 5, and a receiving portion 9 is formed slightly higher than the nailing portion 7, and the receiving portion 9 is slightly lower than the front surface 1a. A cover piece 8 is extended to the fitting convex part 4 side, and in a state where the fitting convex part 4 and the fitting concave part 5 are fitted, the covering piece 8 covers the nailing part 7 and is placed on the receiving part 9. It is designed to be installed. Fitting convex part 4 and fitting concave part 5
At both side edges of the panel adjacent to the edge on which is formed, as shown in FIG. 5, the heat insulating material 3 and the other metal skin 2 are left with one metal skin 1 (which is on the front side in the construction state). Is cut, and the remaining metal sheath 1 is bent so as to face the side end surface of the heat insulating material 3 to form the connection piece 6. In this case, on both side edges of the connection piece 6, shielding pieces X which are connected to the metal outer skin 1 which becomes the outer surface 1 a in the construction state and have a surface in a direction orthogonal to the connection piece 6 are formed by bending.

The shielding piece X is formed on the fitting convex part 4 and the fitting concave part 5 side, and FIG. 1 mainly shows the shielding piece X on the fitting concave part 5 side. There is a shielding piece portion Xa formed by extending a step portion with the receiving portion 9 and an shielding piece portion Xb formed by extending a step portion between the receiving portion 9 and the nailing portion 7. The shielding piece X on the side of the fitting projection 4 is formed so as to extend the tip vertical piece 8a of the covering piece 8 toward the connecting piece 6 and to face the shielding piece portion Xa. At the tip of the connection piece 6, a joint piece Y substantially orthogonal to the connection piece 6 extends outward.

The heat insulating panels A, A have the right end in FIG. 4 as the upper part, and the lower fitting projection 4 is fitted in the upper fitting recess 5 and is connected via the packing P. Because Then, for example, as shown in FIG.
The connection on the connection piece 6 side is performed by longitudinal joints in which the heat insulation panels A, A are juxtaposed in the left-right direction. In this case, the joint pieces Y, Y can be used as a backup material and the caulking agent Z can be filled. is there. In this case, the lower part of the joint pieces Y, Y is filled with the heat insulating member 11 to prevent dew condensation at the joint portion, and to realize a joint structure of fireproof specification. In this case, filling and holding of the heat insulating member 11 are performed by the joint pieces Y, Y.

FIG. 6 (b) shows a joint part having a sufficient fireproof specification and watertight specification. A substantially U-shaped water-blocking plate 12 is fitted to the connection piece 6, 6 on the back side of the panel. The primary caulking agent 13 is filled in the gap generated in the state of being attached, and then the caulking agent Z is filled on the joint pieces Y, Y. Thus, the fire resistance is enhanced by the water stop plate 12,
The watertightness is enhanced by the double caulking agents 13, Z. In FIG. 6, reference numeral 10 denotes a heat insulating material.

According to such a configuration, at the concave / convex fitting portion between the fitting convex portion 4 and the fitting concave portion 5, the packing P is interposed to obtain sufficient airtightness and watertightness, and to provide heat insulation. The side end surfaces of the fitting convex portion 4 and the fitting concave portion 5 of the material 3 are covered with the connecting pieces 6 to prevent the heat insulating material 3 from deteriorating and enhance the weather resistance. In addition, the shielding piece X connected to the metal outer skin 1 on the surface side in the construction state can prevent rainwater from entering from the edge side of the connection piece 6, sufficiently protect the heat insulating material 3, and provide the caulking agent Z , 13, the watertightness can be greatly increased, the fire resistance can be enhanced, and the exterior of the building can be beautifully finished and the appearance of the building can be greatly enhanced.

In the above embodiment, the present invention was applied to the heat insulating panel A provided with the covering piece 8, but FIGS. 8 (a) and 8 (b)
As shown in (c), it goes without saying that the present invention may be applied to a heat insulating panel having no cover piece 8.

[0016]

According to the first aspect of the present invention, a sufficient watertightness is provided at the concave / convex fitting portion between the fitting convex portion and the fitting concave portion.
The side faces of the fitting projections and fitting recesses of the heat insulating material are covered with the connecting pieces to avoid deterioration of the heat insulating material and increase the weather resistance. The shielding piece is formed by bending in the direction of
The shield is a shield with an extended step between the surface and the receiving part
One part and the shield part where the step part between the receiving part and the nailing part was extended
And a step portion between the front surface and the receiving portion is extended.
Since the extended shielding piece extends to the end of the joint piece, the shielding piece connected to the metal outer surface on the surface side in the construction state prevents rainwater from entering This has the advantage that the heat insulating material can be sufficiently protected and the airtightness and the watertightness can be greatly improved.

Moreover , since the joint pieces that are substantially perpendicular to the connecting pieces extend outward from the leading edge of the connecting pieces, the joint pieces can be filled with a caulking agent using the joint pieces as a bag-up material. In this case, the filling work of the caulking agent can be performed easily, and the joint part is made to be fireproof specification. This is advantageous in forming joints with fireproof specifications.
