A washer 13 and a nut are attached to a bolt 12 through which a hook 11 is locked to one of the seams 4b of the folded plate structure roofing member 4a, and the hook 11 is passed through a hole 2b formed at the stepped top of the support member 2a. 14 is fitted and tightened and fixed, and the other folded portion 4c of the folded plate structure roof material 4a adjacent to the fixed folded portion 4b is crowned and the overlapped folded portions 4b and 4c are formed. ,
There has been a construction method in which the manual type fastening device 15 or the electric type fastening device 16 is used for fastening.

[0005]

However, according to the construction method shown in FIG. 8, since the holes are formed in the folded plate structure roofing material 4 itself by the bolts 5, the cause of water leakage is built-in. It takes time and effort to fit the packing 8 and the washer 9 into each bolt 5 and rotate and tighten the nut 10 to fix it, and the bolts and nuts are exposed to the outside, which is unattractive and also during work. In addition, the packing 8, the washer 9, or the nut 10 is inadvertently dropped and lost, resulting in a shortage of the number.

Further, according to the construction method shown in FIG. 9, the drawback of making a hole in the folded plate structure roofing material 4a itself is solved, and the appearance is improved, but manual fastening is required for fastening the seam portions 4b, 4c. It takes time because the formula uses the seam clamp 15 and the heavy electric type seam clamp 16, and they are inadvertently dropped due to an operation mistake during the work near the roof end, and the workers therebelow are injured. There is a risk of causing the suspension member 11 to be damaged by the bolt 12, the washer 13 and the nut 14 and the supporting member 2a.
Since it has to be fastened and fixed in place, the amount of work is the same as that of the former construction method, and it is complicated. Furthermore, the suspension 11, bolt 12, washer 13 or nut 14 is used during the work.
It is also true that there are shortcomings, such as carelessly dropping and losing and running out of numbers.

Both of the construction methods require skilled workers such as skilled craftsmen who can work at high places, but due to the recent lack of manpower, it is impossible to replenish them.

Therefore, the present invention provides a folded plate structure roof that does not require a high level of skill and can be quickly, easily, and safely roofed even by an unskilled person if he / she can work in high places.
