Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a coated metal enclosure that is completely watertight and airtight, and is expandable and contractible against thermal expansion and contraction, earthquakes, etc. This end connection is also made to be able to cope with thermal stress due to thermal expansion and contraction and external forces caused by earthquakes.In particular, the longitudinal direction of the end accessory material is configured to be expandable and contractible at the joint part, and the joint part etc. is made watertight. The present invention also relates to an end joining device in a coated metal envelope that can be made airtight.

[Conventional technology and its problems]

Recently, there has been a lot of research and development into coated metal envelopes that are made watertight and airtight by seam-welding coated metal materials (mainly stainless steel) on the inner and outer surfaces of structures, and are also expandable and contractible. . It is strongly desired that the end joint at one end of the coated metal envelope be able to cope with thermal stress, etc., and that the joint be watertight and airtight. In addition, if the end joint is constructed using a long end material with relatively large corners, an extremely large thermal stress will occur due to thermal expansion and contraction in the longitudinal direction, resulting in large deformation of the corner. There have been drawbacks such as distortion or damage.

[Means to solve the problem]

In order to solve the above problem, the inventor has made extensive research and has developed an X A first joint in the X direction is formed, and these are sequentially repeated on the top of the structure to form a coated metal envelope, and the longitudinal direction of the first joint in the X direction is perpendicular to the side surface of the structure. Then, the ends of the first joint in the X direction are bent so as to touch the main plate, and the ends of the main plate are bent together with the above points to form a continuous rising part of the end, and a hanging shape is formed on one side of the flat part. A bent part with a backing plate is formed on the surface side of at least one end in the longitudinal direction of the end part of an appropriate length, and a rising part is formed on the other side, and the end parts are facing each other. Seam weld the bent part with the backing plate to the second position in the X direction.
A joint part is formed, and the part near the rising part of the second joint part in the X direction is bent so as to be in contact with the flat part, and this part is raised to form a continuous rising part, and the rising part is connected to the connected part. An end joining device in a coated metal envelope in which a Y-direction joint part is formed by seam welding to a rising part of the provided end part, and a hanging part of the end part accessory material is attached to the side surface. As a result, even if the corner part of the end part material is large and thermal distortion is extremely likely to occur in that part, the thermal expansion and contraction etc.
Thermal expansion and contraction in the width direction (direction along the side) of the coated metal envelope can be handled at the first joint in the X direction, and The thermal expansion/contraction in the direction perpendicular to the part is Y
This problem can be solved by using a directional joint, which can prevent any thermal distortion from occurring in the coated metal envelope and the end joint, and can join the end joint in a watertight and airtight manner. It is resolved.

The contact plate 12, the bent portion 11, and the corner portion are joined by seam welding. The bent portion 1 with the contact plates 12, 12 for each end part material D, D in this way
1 and 11 face each other, and are overlapped and seam welded to form a second joint portion 13 in the X direction (see FIG. 3). The second joint portion 13 in the X direction is configured to be openable near the flat portion 8 or near the drooping portion 9 so as to be expandable and contractible. When welding the seam, the end of the rising portion 10 is opened outward (see Figure 3), and
A portion of the second joint portion 13 in the X direction near the rising portion 10 is folded back onto the flat portion 8, and the folded portion is raised to the rising portion 10 to form a continuous rising portion 10 (see FIG. 4). That is, the portion of the second joint portion 13 in the X direction near the rising portion 10 is folded back and overlapped with the rising portion 10 . Such a continuous rising portion 10
