A gap is formed at the corner of the wall 3 and the rising wall 3. For this reason, even if the coated metal material B thermally expands and contracts in its longitudinal direction in response to the outside temperature, the curved portion 7 may escape into the gap (see the chain line in Figure 8), or this curved It acts to stretch the portion 7, and responds well to the thermal expansion and contraction of the covering metal material B, which has the effect of reliably preventing the occurrence of deformation and damage to the covering metal envelope due to thermal stress, etc. .

Furthermore, conventionally, in order to attach a coated metal envelope to a base portion having a rising portion, a separate wall joining member was provided and seam welding was performed. As a result, the number of parts inevitably increases, and the seam welding must be performed vertically and horizontally, making the seam welding work extremely troublesome. However, in the coated metal envelope of the present invention, In this case, the number of parts is small (it is possible to do so, and the seam welding of 10 expansion joints can be performed in an almost continuous straight line from the rising wall 3 side of structure A toward the groove 4 (the opposite direction is also possible). In addition, the covering metal material B has a curved portion 7 formed therein, and has the advantage that the work is easy and construction efficiency can be greatly improved. The addition of curved parts makes the coated metal envelope extremely elegant and original in appearance.
