And seam welding to form the Y direction first expansion joint,
By repeating these steps in sequence, a partially covered metal enclosure is formed on the upper part of the structure so that the longitudinal direction of the Y direction first expansion joint is parallel to the wall surface of the structure and the flat part A rising part is formed on one side, and a relatively high vertical part is formed on the other side.A bending part is formed on the surface side of at least one end in the longitudinal direction of an accessory material of an appropriate length, and the rising part is formed. Part is seam welded to the side wall rising part of the partially covered metal enclosure closest to the wall to form the Y-direction second expansion joint part, and the Y-direction first expansion joint part and the Y-direction second expansion joint part. The part near the outer end of the part is folded back onto the main plate, etc., and the end of the main plate is raised together with this folded back portion to form the end rising part, and this and the bent part are made continuous, and the vertical part of the accessory material is the wall part. And the partially covered metal enclosures thus arranged so as to face each other with an appropriate interval. Then, an intermediate material in which rising edges are formed on both sides in the width direction of the flat L-shaped sub-main plate when viewed from the side is inserted into this space portion, and the both rising edges are formed at the both end rising portions and both bent portions. Since it is a wall fitting device in a covered metal enclosure in which two X-direction expansion joints are formed by seam welding while polymerizing, watertightness and airtightness are perfect, and against earthquakes, thermal expansion and contraction, etc. Even in the wall mounting of the covered metal enclosure that is expandable and contractible, it is possible to cope with thermal stress and the like, and especially the longitudinal direction of the accessory material is configured to be expandable and contractible, and its joint part can be made watertight and airtight. Further, it is possible to extremely easily attach and install the partially covered metal enclosures to each other, the construction efficiency is increased, and the above problems are solved.

〔The invention's effect〕

In the present invention, the side rising parts are provided on both sides of the main plate 1 in the width direction.
Long coated metal material B, 2 formed on the sides B, B side rising portion 2, 2
The Y-direction first expansion joint 6 is formed by polymerizing the two and seam-welding, and these are sequentially repeated to form a partially covered metal enclosure on the upper portion A of the structure, and the Y-direction first expansion and contraction thereof is performed. The longitudinal direction of the joint portion 6 was made parallel to the wall C surface of the structure, the rising portion 8 was formed on one side of the flat portion 7, and the vertical state 9 having a relatively high height was formed on the other side. A bent portion 10 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 rising portion 8 is formed on the side rising portion 2 of the partially covered metal enclosure which is closest to the wall. Second in Y direction after seam welding
Expansion joints 11 are formed, and the Y-direction first expansion joints 6 are formed.
And the Y-direction second expansion joint portion 11 near the outer end is folded back onto the main plate 1 and the like, and the end of the main plate 1 is raised together with this folded portion to form an end rising portion 12, and this and the bent portion 10 are made continuous, The vertical portion 9 of the accessory material D is attached to the wall portion C, and the partially covered metal enclosures thus arranged are arranged so as to face each other with an appropriate interval, and the interval is The intermediate member 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 the portion, and the rising edges 14 and 14 are made compatible with each other at the both side rising portions 12 described above. , 12 and both bent parts 10, 10 are polymerized and seam welded to form two X direction expansion joints 16, so that first, the thermal expansion and contraction of the entire coated metal enclosure in the X direction and Y direction. It is possible to prevent the occurrence of thermal strain due to, and secondly to prevent the thermal strain due to thermal expansion and contraction from occurring even when the accessory materials D and D are connected to each other. It can, an effect such as workability in the third can very well.

To elaborate on these effects, first, the partially covered metal enclosure composed of the elongated covered metal materials B, B, ...
At the outside air temperature or the like, thermal expansion or contraction occurs in the longitudinal direction of the coated metal material B (in the direction parallel to the wall portion C) to generate thermal stress in the partially coated metal enclosure. Insert
The X-direction expansion joint portion 16 is formed by two overlapping edges 14 and 14 which are overlapped with the rising portions 12 and 12 and the bent portions 10 and 10, and is partially covered with metal. The thermal strain due to the thermal expansion and contraction of the outer enclosures can be reliably eliminated.
By the appropriate opening and closing action of the directional expansion joint part 16, it is possible to absorb all the expansion and contraction of the partially covered metal enclosure in the longitudinal direction, and to prevent any thermal stress. Therefore, it is possible to prevent heat distortion and damage.

Particularly, in the present invention, the bent portion 10 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 10, 10 between the accessory materials D and D are seam welded. Since it is formed as a part of the X-direction expansion joint portion 16, even if the accessory material D having relatively large corner portions (the flat portion 7 and the vertical portion 9) thermally expands and contracts in the longitudinal direction, All the expansion and contraction can be absorbed by the X-direction expansion joint section 16, and it is a very great effect that the thermal strain and breakage which are likely to occur at the corners of the accessory material D can be surely eliminated.

In the present invention, the partially covered metal enclosures are made to face each other with an appropriate interval, and the rising edges 14 are provided on both sides in the width direction of the flat main L-shaped sub-main plate 13 when viewed from the side in this interval. Inserting the intermediate material E in which X and X are formed, the compatible edges 14 and 14 are overlapped with the rising portions 12 and 12 and the bent portions 10 and 10 of both ends, and seam welding is performed to perform X direction expansion joint portion 16. Since the two end rising parts 12, 12 are not directly seam welded together, the intermediate material E can be inserted after both end rising parts 12, 12 have been formed in advance. it can. That is, since one end rising portion 12 does not get in the way at all and both end rising portions 12 and 12 can be kept in a state of being raised at the same time, the workability is reduced and the workability is extremely high. This is a great advantage that can be made suitable.

Further, by inserting the intermediate member E, the X-direction expansion joint part 16 has two threads, and it is possible to favorably cope with thermal expansion and contraction in the X-direction. That is, the intermediate material E has a synergistic effect of improving the workability and the effect of heat stretchability.

Further, the adjacent partially covered metal enclosure and the accessory material D are connected by the seam-welded Y-direction second expansion joint portion 11, so that thermal strain due to thermal stress generated between them is caused. Can be definitely solved.

For this reason, it is possible to eliminate the occurrence of thermal strain over the entire coated metal enclosure or the entire wall attachment 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 contractable as described above, they are mutually Y-direction first expansion joint part 6 and Y-direction second expansion joint part 11, X. All of the directional expansion joints 16 are seam welded, the wall joints can be made watertight and airtight, and rainwater can be reliably prevented from entering.
