Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a wall covering for a coated metal enclosure that is completely watertight and airtight, and is expandable and contractible against earthquakes, thermal expansion and contraction, etc. The present invention relates to a wall joining device for a coated metal envelope that can cope with thermal stress, etc. even in cases where the accessory material is expandable and contractible in the longitudinal direction, and whose joint portion can be made watertight and airtight.

[Conventional technology and its problems, etc.]

Recently, research and development have been conducted on covered metal envelopes that are made watertight and airtight by seam-welding coated metal materials (mainly stainless steel materials) to the inner and outer surfaces of structures, and are also expandable and contractible. It is also strongly desired that this wall connection be able to cope with thermal stress, etc., and that the attachment portion be watertight and airtight. In addition, if the wall joint is constructed using long materials with large corners, extremely large thermal stress will occur due to thermal expansion and contraction in the longitudinal direction, resulting in large deformation and strain at the corners. Problems such as damage occurred.

[Means to solve the problem]

Therefore, as a result of intensive research to solve the above problems, the inventor has devised the present invention, in which a large number of elongated coated metal members with rising side parts formed on both sides of the main plate are attached to the upper part of the structure. roofing to form a coated metal envelope, the side rising parts of the coated metal materials are seam welded, and the longitudinal direction is parallel to the wall surface of the structure to form a first joint in the Y direction, An accessory material having an L-shaped cross section, in which rising parts and vertical parts are formed on both sides of a flat part, and an L-shaped bent part is formed at one end in the longitudinal direction, the end of the rising part near the L-shaped bent part is made flat. The opposing L-shaped bent parts are overlapped, and the L-shaped bent parts are seam-welded to each other to form an X-direction joint part, and the X-direction joint part is bent so that the rising part comes into contact with the flat part. The portion is raised to form a continuous rising portion, and the rising portion is superimposed on the rising portion of the side closest to the wall of the coated metal envelope to form a second Y-direction joint portion by seam welding. By using the vertical part of the accessory material as a wall joining device in the coated metal enclosure attached to the wall, thermal expansion and contraction in the longitudinal direction of the coated metal material and the longitudinal direction of the accessory material can be prevented. For the X direction joint part,
At the second joint in the X direction, and in response to thermal expansion and contraction in the width direction of the coated metal envelope and accessory materials, thermal stress is applied at the first joint in the Y direction and the second joint in the Y direction. It is possible to prevent the occurrence of deformation and damage caused by such problems, and the wall joint portion can be joined watertightly and airtightly, thus solving the above problems.
