PROBLEM TO BE SOLVED: To make good flashing against rain water by securing a frame to roof backing with machine screws, covering exposed portions such as the screws with the edges of roof backing sheet distributed to a metal roofing material and by covering the gap between the end portion and frame. SOLUTION: A pair of attaching piece 23 stuck out in a girder direction of a frame 20 are fixed to roof boards 17 and purlins 15 which are the roof backing with machine screws. Then, a waterproof steel plate 21 as roofing material is laid to surround the frame 20, edge of the waterproof steel plate 21 is tilted to cover the heads of machine screws 24 and then raised with a tilted piece 25 and a vertical piece 26 formed in one united body. Moreover, a lip 27 of the frame 20 is covered with a pair of reversed Lshaped frame cover 28 and a gap created between a vertical piece 26 of the waterproof steel plate 21 and the side face of the frame 20 is covered from the above. Next, stop fittings 54 is inserted to the inside of the frame 20, a coupling fitting 54 and a coupling bolt 57 is tightened, a contact piece 58 of stop fittings 54 is contacted to the lip 27, and the solar cell module 13 is fixed to frame 20, and the solar cell module 13 is fixed to the frame 20. Thus, the ingress of rain water can be definitely prevented. |
