Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention, in spite of a covered metal enclosure obtained by seam welding all rising parts and the like of a long coated metal material,
The present invention relates to a coated metal enclosure that can be expanded and contracted in the X and Y directions in accordance with the outside air temperature and can significantly improve the construction efficiency.

[Conventional technology and its problems]

In recent years, a coated metal enclosure in which a coated metal material is seam-welded to the outer surface of a structure to perform a watertight construction is being actively researched and developed. However, if all of the rising parts of the coated metal material are seam-welded when they expand and contract according to the outside air temperature, large thermal stress is generated in each part, deformation distortion occurs in the rising parts and flat parts, and in extreme cases. Was sometimes damaged. For this reason, a void is formed in an appropriate place of such a coated metal envelope, and thermal expansion and contraction in the X and Y directions are absorbed at this place. However, at this void portion, the seam welding of watertight fixation cannot be performed, and it is the current situation that another member for covering the void portion from the upper side or the side portion is provided to prevent rain. In this way, in order to form a void and a separate member, not only the construction is extremely troublesome, but also a large number of members are required, which in turn becomes expensive, and the separate member is formed on the outer surface of the coated metal envelope. Since it protrudes, it cannot be attached depending on the location, and there are drawbacks such as impairing the overall appearance. For this reason, it has been considered ideal in the metalworking industry to seam-weld the whole body and joint the whole body so that the whole body can be thermally expanded and contracted in the X and Y directions. Therefore, the applicant solved the problems in Japanese Patent Application No. 55-139645. However, according to the invention, the mounting work of the partially covered metal enclosures is extremely troublesome, and the working efficiency is reduced.

[Means for Solving the Problems]

Therefore, as a result of earnestly researching to solve the above-mentioned problems, the inventor has found that the present invention is adjacent to the side rising part of a long coated metal material having side rising parts formed on both sides in the width direction of the main plate. The side rising portion of the coated metal material of 1 is seam welded to form the X-direction first expansion joint portion, and these are sequentially repeated to form a roof,
The end portion of the X-direction first expansion joint portion is folded back to the main plate surface to continuously form an end rising portion together with this portion, and these same ones are appropriately arranged while their longitudinal directions are in the same direction.

〔The invention's effect〕

In the present invention, the side rising portions are provided on both sides of the main body 1 in the width direction.
Side rising part 2 of the long coated metal material A in which 2, 2 are formed
, The side rising portions 2 of the adjacent coated metal materials A are seam-welded to form the X-direction first expansion joint portion 5, and these are sequentially repeated to form a roof, and the X-direction first expansion joint portion 5 is The end portion is folded back to the surface of the main plate 1 and the end rising portion 6 is continuously formed together with this portion, and the same ones are arranged so that their longitudinal directions are in the same direction and face each other with an appropriate interval. Then, at this space, the rising parts are formed on both sides in the width direction of the bottom main plate 7.
Inserting the intermediate material A ₁ formed with
And the opposite end rising portions 6 and 6 are respectively seam welded to form two Y-direction first expansion joint portions 9, and an X-direction second expansion joint approximately orthogonal to the middle portion in the longitudinal direction. A plurality of parts 10 are provided side by side, and a plurality of X direction second expansion joint parts are provided.
At both ends of 10, there is a Y-direction second expansion joint part which is substantially orthogonal to this.
Since a plurality of 12 strips are formed and the ends of each of them are folded back and polymerized on the X-direction first expansion joint portion 5 to form a coated metal enclosure, first of all, thermal expansion and contraction in the X-direction and Y-direction are performed. The occurrence of thermal strain can be prevented, and secondly, the workability can be extremely improved.

These effects will be described in detail. First, even if the coated metal material A is long and has a large thermal expansion and contraction in the longitudinal direction, it is absorbed by the Y-direction first expansion joint portion 9, and the coated metal material A The heat expansion / contraction in the width direction of each A is absorbed by the X-direction first expansion joint parts 5 provided on both sides thereof. In addition, a plurality of X-direction second expansion joint portions 10 orthogonal to the Y-direction first expansion joint portions 9 are provided at appropriate positions in the longitudinal direction, and both ends of the plurality of X-direction second expansion joint portions 10 are provided. Formed Y-direction second expansion joint portions 12 and 12 substantially orthogonal thereto, and folded back the ends of each of them to overlap with the X-direction first expansion joint portion 5, so that the Y-direction first expansion joints were formed. When the joint portion 9 is long, thermal expansion and contraction tend to occur and thermal stress tends to occur, but the plurality of X-direction second expansion joint portions 10 in the middle can absorb the thermal expansion and contraction almost completely, Further, the thermal expansion and contraction of the coated sub-metal material A _{2 in} the Y direction (longitudinal direction) at the portion having the X direction second expansion joint part 10 is not absorbed by the Y direction first expansion joint part 9,
It is absorbed by the second expansion joint section 12 in the Y direction.

In the present invention, the partially covered envelopes are opposed to each other with an appropriate interval, and the intermediate material A ₁ having the rising portions 8 and 8 formed on both sides in the sub-direction of the bottom plate main plate 7 is inserted into this interval portion. Then, since the two Y direction first expansion joint parts 9 are formed by seam-welding with the end rising parts 6 and 6 facing the compatible rising part 8 respectively, the end rising parts 6 and 6 are directly seamed. Since they are not welded, it is possible to insert the intermediate material A ₁ after forming both the end rising portions 6, 6 in advance. That is, since one end rising part 6 does not get in the way and both end rising parts 6, 6 can be molded at the same time, the processing is simplified, the work is easy, and the workability is excellent. There is a great advantage that Further, the end rising portion 6 can be easily bent and can be easily formed.

Further, by inserting the intermediate member A ₁ , the Y-direction first expansion joint portion 9 has two threads, and it is possible to favorably cope with thermal expansion and contraction in the Y-direction. That is, the intermediate material A ₁ is such that the improvement of the workability and the heat stretchability act synergistically. In addition, for thermal expansion and contraction in the Y direction, multiple Y-direction second expansion joint parts exist.
12 can respond well.

In this way, for thermal expansion and contraction in the Y direction, the two first Y-direction directions are used.
Expansion joints 9,9 and multiple Y direction second expansion joints 12,12
... and cooperate with each other and act synergistically to provide a good response.

As described above, it is possible to absorb the thermal expansion and contraction in the X and Y directions of the coated metal enclosure despite the fact that all seam welding is performed. Compared with this, it is possible to greatly save the member, to prevent the situation in which another member can be protruded to prevent the work from being performed, the appearance can be made elegant, and the work can be performed at low cost.
The presence of such a plurality of X-direction and Y-direction second expansion joint parts 10 and 12 makes it possible for the first time to provide a coated metal enclosure that has been long-awaited in the industry.
