Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses a long coated metal material, and in a coated metal enclosure which is constructed by seam welding, the length limitation is almost eliminated, and the construction is simple and quick. The present invention relates to an enclosure that can be made into a structure that is extremely strong after construction.

[0002]

2. Description of the Related Art Conventionally, a coated metal envelope for seam-welding a coated metal material (mainly a stainless steel material) to the inside and outside of a structure to make it watertight and airtight has been actively researched and developed.

In order to attach the rising portion of the coated metal material to a structure, conventionally, a movable suspension having a tongue piece that is appropriately movable in response to thermal expansion and contraction of the coated metal material has been often used.

This is because the thermal expansion and contraction copes with the thermal stress strain of the coated metal material, and thus of the coated metal envelope.

[0005]

In the above-mentioned tongue sliding type suspension, the structure of the sliding portion of the tongue tends to be complicated,
The number of manufacturing processes is large and the cost is high, and the envelope itself is also expensive.

Further, in the tongue sliding type suspension, the mechanism for sliding the tongue tends to become unstable, and even if a slight external force is generated, the tongue and the base material are fixed to each other. There is also a risk that it will easily come off, which could adversely affect the strength of the entire envelope.

[0007]

Therefore, as a result of intensive studies by the inventor to solve the above-mentioned problems, the present invention was found to be the result of the present invention. Then, the seam welded portion is fixed to the base portion with a restraining suspension at appropriate intervals over the entire length in the longitudinal direction,
By limiting the length of the fixed portion to an envelope formed by seaming welding the coated metal material, the enclosure is configured to sufficiently withstand the load generated during thermal expansion and contraction of the coated metal material. It is possible to eliminate the above-mentioned problems and to perform the construction easily and quickly, and at the same time, after the construction, it is possible to obtain an extremely strong enclosure, which solves the above-mentioned problems and achieves the object. ..
