Is engaged with the concave portion 28 of the second frame member 16 to terminate the joint between the folded metal plates 20 by the metal folded plate mounting structure 10 with the temporary fixing member.
The roof surface is laid while jointing the above with a metal folding plate mounting structure 10 with a temporary fixture.

As described above, the first side surface of the folded metal plate is engaged with the support frame fixed to the upper surface of the roof base material 46, and in this state, the temporary fixing tool 26 is pressed down from the upper surface and elastically mounted in a spring shape. Then, by being closely attached to the support frame, the temporary fixing tool and the first side surface 24a pressed by the temporary fixing tool are tightly fixed to the support frame 18. Thereby, the metal folded plate on the first side is substantially firmly fixed to the support frame. Therefore,
If the metal folded plate on the second side surface is fitted and fitted so as to be pushed down from the upper surface, it is formed into two, three, four,. . . The first side surface is fixed, and the second side surface is further fitted from the upper surface thereof to form an extremely strong folded metal plate roof structure.

Therefore, the first side surface 24a does not float or displace during the construction, and there is no need to make an adjustment for mounting the second side surface 24b of the next folded metal plate 20, and the mounting can be performed immediately. Thus, the efficiency of roofing work with a folded metal plate can be increased, and a large strength against wind pressure from the lower surface side can be maintained.
