Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is characterized in that, despite the fact that the rising portion of a long coated metal material is all seam welded, the entire envelope is resistant to the outside temperature. The present invention relates to a coated metal envelope that can prevent deformation and damage due to thermal stress even if thermal expansion and contraction occur in the X and Y directions.

[Conventional technology and its problems, etc.]

Recently, research and development have been conducted on a watertight coated metal enclosure in which a coated metal material is seam-welded to the outer surface of a structure. However, if all the rising parts of the coated metal material are seam welded, large thermal stress will occur in each part when it expands and contracts depending on the outside temperature, causing deformation and strain in the rising parts and flat parts, and in severe cases. could be damaged. For this reason, voids are formed at appropriate locations in such an envelope to prevent deformation and damage due to thermal stress and the like against thermal expansion and contraction in the X and Y directions.

However, it is not possible to seam weld the gap in a watertight manner, and the current situation is to provide a separate member to cover the gap from the top or side to protect it from rain. In this way, providing a separate member for forming the void not only requires extremely troublesome construction, but also
It requires many parts and is therefore expensive, and the other parts protrude from the outer surface of the enclosure, making it impossible to install in some places.
There were drawbacks such as detracting from the overall appearance. Also,
With a configuration in which separate members are provided, the entire structure cannot be brought into water-tight contact. For this reason, we seam welded the whole thing and joined it, and
It was considered ideal in the metal plate industry to be able to expand and contract thermally in the Y direction, but this was technically difficult.

[Means for solving problems]

Therefore, as a result of extensive research in order to solve the above-mentioned problems, the inventor has developed the present invention into a side riser part of a coated metal material in which side riser parts are formed on both sides in the width direction of a long main plate. , seam-weld the rising side portions of adjacent coated metal materials to form a first X-direction expansion joint, and bend the end of this first Along with the lever part, an end rising part is continuously formed on one side in the longitudinal direction, and a side rising part of the coated metal material is seam welded to this continuous end rising part to form the first Y direction expansion joint part. A second Y-direction expansion joint portion is provided by seam welding the side rising portion of the covering metal material to the other side rising portion of the coated metal material having this first Y-direction expansion joint portion, and this is sequentially roofed. Then, while separating the first Y-direction expansion joint at an appropriate midpoint in the longitudinal direction, a second X-direction expansion joint that is perpendicular to the longitudinal direction of the first Y-direction expansion joint is attached at this joint. A third Y-direction expansion joint part perpendicular to the longitudinal direction of this second X-direction expansion joint part is provided at one longitudinal end of the second X-direction expansion joint part, and both ends of this joint part are bent to form a third Y-direction expansion joint part in the first X-direction. By forming a coated metal envelope that is superimposed on the expansion joint, and the other end of the second X-direction expansion joint is bent and superposed on the second Y-direction expansion joint, all the rising parts of the coated metal can be removed. Even if welded, the 1st X direction expansion joint, the 2nd
Direction expansion joint section, 1st Y direction expansion joint section, 2nd Y direction expansion joint section
At the direction expansion joint part and the third Y direction expansion joint part, deformation strain and damage due to thermal stress etc. can be prevented from occurring due to thermal expansion and contraction in the X direction and Y direction that occurs in the whole or each part of the enclosure, And the number of parts can be reduced,
As a result, it is possible to perform construction at a low cost, and it is possible to provide a covered metal enclosure that has an elegant appearance and is completely watertight without protruding separate members as in the conventional case, thus solving the above-mentioned problems.

A plurality of movable hangers B are provided at appropriate intervals in the longitudinal direction of the side rising portion 2. Then, the side rising portion 2 where the movable tongue piece 4 exists

These steps are repeated one after another to form part of the outer enclosure. In this case, the lengths in the longitudinal direction are formed to be approximately the same. Further, the vicinity of the end in the longitudinal direction of the intermediate portion in the juxtaposition direction may be cut off or formed short.

A part of the outer envelope from the longitudinal end of the first X-direction expansion joint part 5 (a part near this end) is bent onto the main plate 1 surface, and this part and the end of the main plate 1 ( The longitudinal end portions) are bent to form continuous end rising portions 6, 6, . . . . The side rising portions 2 of the elongated coated metal material A are superimposed on these continuous end rising portions 6, 6, . . . and are seam welded to form the first Y-direction expansion joint portion 7.

That is, this first Y-direction expansion joint part 7 is orthogonal to the longitudinal direction of the outer envelope and the longitudinal end rising parts 6, 6, etc. (including cases where they are substantially orthogonal).
The side rising portion 2 on one side of the covering metal material A is seam welded. This first Y-direction expansion joint portion 7 may also be cut out at an appropriate midpoint in its longitudinal direction, or may be left unformed.

The length of the first Y-direction expansion joint 7 in the longitudinal direction (X direction) of the covering metal material A is, for example, about 25
This is to prevent deformation and damage due to thermal stress, etc. against thermal expansion and contraction when the temperature exceeds m.
It is generally formed higher than the height of the 1X direction expansion joint section 5 (for example, about 5 cm to about 8 cm). In some cases, the heights may be the same.

The side rising portion 2 of the adjacent covered metal material A parallel to this is superimposed on the side rising portion 2 of the other side of the covered metal material A having the first Y-direction expansion joint portion 7 on one side. A second Y-direction expansion joint portion 8 is formed by seam welding together with a movable tongue piece 4 interposed at a proper location. These steps are repeated one after another to form part of the outer enclosure. This partial envelope and the above-mentioned partial envelope are provided so that their longitudinal directions are orthogonal (including cases in which they are substantially perpendicular), so that the entire or substantially entire covered metal envelope is covered. has been done.

9 is a second X-direction expansion joint, and its first Y
While separating appropriate points in the middle of the longitudinal direction of the direction expansion joint section 7 (at intervals of approximately 6 m in the embodiment), a section ( (including cases where they are substantially orthogonal) are provided. That is, in the second X-direction expansion joint part 9, the intermediate separated end portion of the first Y-direction expansion joint part 7 is the main plate 1, or the main plate 1 of an appropriate square or rectangular covering sub-metal material A'. This portion and the side or end portion of the main plate 1' are bent together to form sub-rising portions 10, and these sub-rising portions 10, 10 face each other. Constructed with seams welded. This height is formed to be equal to the height of the first Y-direction expansion joint section 7.

To actually construct the second X-direction expansion joint 9, the covering metal material A is made to have an appropriate length, or another covering sub-metal material A' is suitably bent.

Furthermore, even if thermal expansion and contraction occurs in the longitudinal direction (X direction) of the first Y-direction expansion joint 7, the second X-direction expansion joint 9 can be opened and closed by the opening and closing action of the second This is to prevent the first Y-direction expansion joint 7 from being deformed or damaged due to thermal stress or the like.

11 is a third Y-direction expansion joint;
At one end of the 2X direction expansion joint part 9 near the first X direction expansion joint part 5 (lower side of the first Y direction expansion joint part 7 in FIGS. 3 to 7), the longitudinal direction Both ends of the third Y-direction expansion joint 11 are bent and overlapped with the first X-direction expansion joint 5.

The other end (upper side in FIGS. 3 to 7) of the second X-direction expansion joint 9 is bent and overlapped with the second Y-direction expansion joint 8. The first

There are a plurality of embodiments of the third Y-direction expansion joint section 11, which will be described later.

Moreover, the third Y direction expansion joint part 11
It is formed to have the same height as the direction expansion joint part 5. Each of the above-mentioned expansion joints is formed so that it can expand and contract in only one direction, and the lower portions of both rising portions are open. Even if another expansion joint part is bent and overlapped orthogonally to this expansion joint part, it is still configured to be expandable and contractible only in that one direction. That is, the bent portion cannot perform the original expansion and contraction action, and is provided exclusively for seam welding on the overlapping side.

Furthermore, the X direction and Y direction of each expansion joint described above means that the joint itself can accommodate expansion and contraction in that direction, and its longitudinal direction does not face in that direction.

Moreover, what is shown in FIGS. 3 to 7 are schematic plan views diagrammatically representing each expansion joint,
The T-shaped end of each wire refers to the bend, which is superimposed on the other expansion joint.

In the one shown in FIG. 3, the length of the second X-direction expansion joint 9 is shorter than that in FIG. 1. What is shown in FIG. 6 is a modification of the first embodiment, in which the length of the third Y-direction expansion joint 11 of FIG. 1 (first embodiment) is doubled. In this case, a substantially square covering sub-metal material A' is used.

The second embodiment of the third Y-direction expansion joint 11 is one in which a plurality of strips (two strips in the drawing) are provided on one end side of the second X-direction expansion joint 9, as shown in FIGS.
The one shown in Fig. 7 is the basic one, and the one shown in Fig. 5 is a modification thereof. In some cases, the second embodiment may be further modified so that the other end (the upper side in FIG. 7) of the second X-direction expansion joint 9 is made longer (see FIG. 7). ).

In addition to the above, the second X-direction expansion joint 9 and the Y
There are many embodiments (not shown) in which the lengths of the third expansion joint portions 11 are set as appropriate.

Furthermore, various second X-direction expansion joints 9 are actually
And to construct the third Y direction expansion joint part 11,

Then, bend it accordingly and then seam weld the whole part, or bend the covering metal material A and the covering sub-metal material A' of an appropriate length to perform seam welding at the appropriate location. This is then bent and then the whole thing is seam welded.
The construction order may be changed as appropriate depending on the embodiment.

〔Effect of the invention〕

In the present invention, the side rising parts 2 of the adjacent covering metal material A are attached to the side rising parts 2 of the covering metal material A in which the side rising parts 2, 2 are formed on both sides of the elongated main plate 1 in the width direction. Seam welding is performed to form a first X-direction expansion joint part 5, and the end of the first X-direction expansion joint part 5 is bent so as to come into contact with the main plate 1 surface, and together with this part, an end is formed on one side in the longitudinal direction. The continuous end rising portions 6 are formed continuously, and the continuous end rising portions 6, 6...
..., the side rising portion 2 of the coated metal material A is seam welded to form the first Y direction expansion joint portion 7, and this first Y direction expansion joint portion 7 is formed.
A second Y-direction expansion joint portion 8 is provided by seam welding the side riser portion 2 of the coated metal material A to the other side riser portion 2 of the coated metal material A having the first Y-direction expansion joint portion 7, and this is sequentially attached. While separating the first Y-direction expansion joint portion 7 at an appropriate location in the longitudinal direction, a second X-direction expansion joint portion 9 perpendicular to the longitudinal direction of the first Y-direction expansion joint portion 7 is installed at this location. 1
a third Y-direction expansion joint portion 11 perpendicular to the longitudinal direction of the second X-direction expansion joint portion 9 is provided at one longitudinal end of the second X-direction expansion joint portion 9;
The covered metal outer part is bent at both ends and overlapped with the first X-direction expansion joint part 5, and the other end of the second X-direction expansion joint part 9 is bent and overlapped with the second Y-direction expansion joint part 8. Firstly, even if thermal expansion and contraction occurs in the entire envelope, it can respond to the deformation due to the opening and closing action of the joint, and each part is free from deformation and strain due to thermal stress etc. It is possible to prevent the occurrence of damage, and secondly, even if the first Y-direction expansion joint part 7 is large and long, it can cope well with thermal expansion and contraction, and the third part is watertight and airtight, and construction is easy and inexpensive. It has the effect of being able to provide

To explain these effects in detail, first,
, the length of the covering metal material A in the longitudinal direction is long,
Even if thermal expansion/contraction occurs in this longitudinal direction, it is responded to by the opening/closing action of the first Y-direction expansion joint 7 that is substantially orthogonal to this longitudinal direction, and thermal expansion/contraction occurs in the longitudinal direction of this first Y-direction expansion joint 7 itself. Therefore, it is attempted to generate strain due to thermal stress, etc., but this can be responded to by opening and closing the second X-direction expansion joint section 9 which is substantially orthogonal to the longitudinal direction of the first Y-direction expansion joint section 7.
Furthermore, thermal expansion and contraction in the longitudinal direction of the second X-direction expansion joint 9 itself can be effectively accommodated by the opening and closing action of the second Y-direction expansion joint 8 and the third Y-direction expansion joint 11, which are substantially perpendicular to the longitudinal direction. I can respond.

In addition, even if the length of the first Y-direction expansion joint 7 is long (the roofing surface is large) and the joint or main plate undergoes regular or irregular thermal expansion and contraction, the second X-direction expansion joint 9 By opening and closing the opening and closing action, it is possible to almost prevent deformation and damage caused by thermal stress and the like.

In addition, thermal stress is generated in each part of the envelope by the opening and closing actions of the first X-direction expansion joint part 5, the first Y-direction expansion joint part 7, the second Y-direction expansion joint part 8, and the third Y-direction expansion joint part 11. This makes it possible to completely prevent deformation and damage caused by thermal stress and the like.

In this way, even though the entire envelope was seam welded, the coated metal envelope was able to respond favorably to thermal expansion and contraction in the X and Y directions, unlike conventional methods. Compared to forming voids and attaching separate parts, construction is significantly simpler, the number of parts can be significantly reduced, and situations such as protruding separate parts that make construction impossible can be avoided, resulting in an elegant appearance. Furthermore, a fundamental difference from the conventional method is that the present invention allows the entire envelope to be completely watertight. In addition, the construction is simple and the number of parts can be saved, so it can be provided at a low cost. As described above, the completely watertight and thermally expandable coated metal envelope is an advanced invention that has been developed for the first time in the metal sheet industry, and can meet many demands.
