〔The invention's effect〕

In the present invention, side rising parts 6, 6 are formed on both sides of the main plate 5 in the width direction, and one end in the longitudinal direction of the main plate 5 and both side rising parts 6, 6 has an appropriate radius of curvature when viewed from the side. In addition, the curved portion 7 having a shape of about 1/4 circle is formed, and only the height of both side rising portions 6, 6 of the curved portion 7 is made lower than the height of the other side rising portions 6. A plurality of coated metal materials B are arranged on the upper portion 1 of the structure A, in which the rising wall 3 is formed on one of the upper portions 1 and the other is the flat eaves portion 4. The side rising portions 6, 6 of the adjacent coated metal material B
And the curved portions 7, 7 are seam welded to each other to form the expansion joint portion 10, and these are sequentially repeated to cover the upper portion 1 of the structure A, and the upper end of the curved portion 7 of the coated metal material B is covered. It is arranged so as to substantially abut on the inside of the rising wall 3, and its coated metal material B
Of the elongate end of the elongate joint 8 at the other end in the longitudinal direction of the main plate 5 and the end of the main plate 5 at which the expansion joint 10 is bent so as to contact the main plate 5
Is a covered metal enclosure connected to the connecting pieces 11 of the eaves part arabesque material C provided at the four eaves parts. First, the upper part 1 of the structure A and the rising wall 3 are integrally formed. It can be watertightly and airtightly coated and can be easily constructed. Secondly, it can cope with thermal expansion and contraction of the coated metal material B. Thirdly, the eaves section A of the structure A can be well repaired. There is an effect that it can be easily installed and is elegant.

To describe these effects in detail, the coated metal material B has an upward curved portion 7 formed at its end,
By placing the coated metal material B on the upper portion 1 while disposing the upper end of the curved portion 7 inside the rising wall 3, the upper portion 1 such as the roof of the structure A and the rising wall 3 are naturally placed. Can be integrally and watertightly and airtightly covered.

Next, when the upper portion 1 and the rising wall 3 are integrally covered with the curved portion 7 of the coated metal material B, the curved portion 7 forms the upper portion 1.
A gap is formed between the corner of the rising wall 3 and the rising wall 3. Therefore, even if the coated metal material B thermally expands and contracts in the longitudinal direction in response to the outside air temperature, the curved portion 7 having a shape of about 1/4 circle may escape into the void portion (chain line in FIG. 8). Section), and acts to extend the curved portion 7 and responds well to the thermal expansion and contraction of the coated metal material B, so that deformation strain or damage due to thermal stress or the like is generated in the coated metal envelope. There is an effect that can be surely prevented.

Further, conventionally, in order to attach the coated metal envelope to the base portion having the rising portion, another wall fitting material is provided and seam welding is performed. Therefore, the number of members inevitably increases, and the seam welding must be performed in the vertical and horizontal directions, and the seam welding work is extremely troublesome, but in the coated metal enclosure of the present invention. The number of members can be reduced, and seam welding of 10 expansion joints can be performed on a straight line from the rising wall 3 side of the structure A toward the eaves section 4 (or vice versa). There is an advantage that the work can be done easily and the construction efficiency can be greatly improved.

Next, in the eaves section 4 of the structure A, the coated metal material B and the eaves section arabesque material C are connected to each other to substantially integrally cover the upper section 1 and the eaves section 4, and a good eaves section is repaired. You can

For this reason, it is not necessary to newly perform drainage repairs at the four eaves portions, which in turn saves construction costs.

Further, a curved portion 7 is formed on the coated metal material B, and the coated metal outer body constituted by the coated metal material B is
With the addition of curved parts, the appearance can be extremely elegant and original.
