Detailed Description of the Invention

[0001]

[0002]

2. Description of the Related Art A flat roof using an eye deck roof in a conventional steel frame structure is disclosed in Japanese Utility Model Publication 5-24.
As in Japanese Patent No. 740 and Japanese Utility Model Publication No. 5-24741, the lower end of each leg rib is directly attached to a vehicle (beam, purlin, etc.) to form a roof. Further, a method of constructing a folded plate roof in which a corrugated metal roof plate is attached to a vehicle body by a corrugated tight frame is also well known.

[0003]

However, in the case of the former (using an eye deck roof) in the above-mentioned prior art, the lower end of the leg-shaped rib portion of the roof plate is directly welded to the vehicle body or screwed. Since the worker usually extends the roof from the top of the roof to the back side of the roof, the workability is poor and there is a great risk of accidentally dropping onto the ground. There were many. Also, in the case of the latter (using a tight frame), the roof plate and the tight frame are simply shaped and molded into a corrugated form, and are simply fitted and attached to each other.
Moreover, when the waterproof structure is provided on the upper surface of the roof plate, there is a problem that the roof plate is corrugated, so that the construction is troublesome.

[0004]
