<P>PROBLEM TO BE SOLVED: To provide a folded-plate roof material, which is easily handled in work, capable of being strongly attached, and reducing distortion and deformation due to temperature change. <P>SOLUTION: The folded-plate roof material A comprises a bottom part 1 and a pair of side parts 2 projected obliquely upwards from both side ends thereof. For the bottom part 1, low stage parts 32 recessed at a position lower than the side ends are formed at both side parts, and a projection stage part 31 projected upwards from the low stage part 32 stepwise is formed between the low stage parts 32 and 32. For the side part 2, a part 3 to be locked to a locking part 4 projected on the side face of a tight frame B is formed on the lower side of the middle in the vertical direction, and a reinforcing rib part 5 inclined and bent to the surface side is formed on the upper side of the part 3 to be locked. <P>COPYRIGHT: (C)2012,JPO&INPIT |
