The longitudinal direction of the X-direction first expansion joint part 6 is the structure. The wall portion C of the X-direction first expansion joint portions 6, 6, ... Is folded back onto the main plate 1 so as to be orthogonal to the wall surface C plane of the object, and the end of the main plate 1 is raised together with this folding point. Department rising section 7

A bent portion 11 is formed on at least one surface side, and a rising portion 9 is seam-welded to the end rising portion 7 to form a Y-direction expansion joint portion 12. The end of the Y-direction expansion joint portion 12 is a side. Part rising part 2 or bent part
The partially covered metal enclosure in which the vertical portion 10 of the accessory material D is attached to the wall portion C is folded back to 11, and the bent portions 11 and 11 adjacent to each other are provided at appropriate intervals. Arranged to oppose,
The intermediate material E having the rising edges 14 and 14 formed on both sides in the width direction of the flat main L-shaped sub-main plate 13 when viewed from the side is inserted into this space portion, and the rising edges 14 and 14 are made to rise simultaneously on both sides. First, the wall fitting device for the covered metal enclosure in which the X-direction second expansion joint part 16 is formed into two pieces by overlapping the parts 2, 2 and the bent parts 11, 11 and seam welding is used. It is possible to prevent thermal strain from occurring due to thermal expansion and contraction in the X and Y directions of the entire coated metal enclosure, and secondly, even if the accessory materials D and D are connected to each other, thermal strain due to thermal expansion and contraction also occurs in this material. Can be prevented, and thirdly, the workability can be extremely improved.

To elaborate on these effects, first, the partially covered metal enclosure composed of the elongated covered metal materials B, B, ...

After forming 11, 11 the intermediate material E can be inserted. In other words, there is a great advantage that the intermediate member E can be inserted without the one bent portion 11 interfering, the work is easy, and the workability is extremely suitable.

Further, by inserting the intermediate member E, the second expansion joint portion 16 in the X direction has two threads, and thermal expansion and contraction in the X direction can be favorably coped with. That is, the intermediate material E has a synergistic effect of improving the workability and the effect of heat stretchability.

Furthermore, thermal expansion and contraction in the X direction can be favorably dealt with by the X-direction first expansion joint part 6, which has a plurality of lines.

As described above, for thermal expansion and contraction in the X direction, two X-direction second expansion joint parts 16 and 16 and a plurality of X-direction first expansion joint parts are provided.

By forming two X-direction second expansion joint parts 16 by seam welding by means of seam welding, thermal strain due to thermal expansion and contraction of the partially covered metal enclosures can be reliably eliminated, and the X-direction second expansion joint part is formed. In the portion 16, the thermal strain due to the thermal expansion and contraction in the longitudinal direction of the Y-direction expansion joint part 12 itself can be completely eliminated.

In particular, in the present invention, the bent portion 11 is formed on the surface side of at least one end in the longitudinal direction of the accessory material D having an appropriate length, and the bent portions 11, 11 of the accessory materials D, D are seam welded. Since it is formed as a part of the X-direction second expansion joint portion 16, the accessory material D having a relatively large corner portion (the flat portion 8 and the vertical rib portion 10) is
Even if it expands and contracts in the longitudinal direction, all of this expansion and contraction can be absorbed by the X-direction second expansion joint section 16, and it is possible to reliably eliminate the thermal strain and breakage that are very likely to occur at the corners of the accessory material D. it can.

For this reason, it is possible to eliminate the occurrence of thermal strain over the entire coated metal enclosure or the entire wall joining portion.

Further, with respect to an external force such as an earthquake, it is configured to be able to expand and contract independently of the upper portion A and the wall portion C of the structure, so that it is extremely unlikely to be deformed or damaged and can be strong against an earthquake or the like. .

Even if the coated metal material A, the intermediate material E, and the accessory material D are configured to be expandable and contractible as described above, they are mutually arranged in the X-direction first expansion joint part 6 and the X-direction second expansion joint part 16, Y. All of the directional expansion joints 12 are seam welded, the wall joints can be made watertight and airtight, and rainwater intrusion can be reliably blocked.
