PROBLEM TO BE SOLVED: To reduce the number of parts and a manday and contrive reduction of cost by lowering height of the upper face of the main house of a solar battery setting roof part, and avoiding protruding a solar battery larger than a general roof through a sheathing board and a metal plate roofing material. SOLUTION: The upper face of main houses 4, 5 on a solar battery-setting roof part 2 is made lower than that of the main house 3 of a general roof part, and a sheathing roof board 6 is set thereon. Therefore, a step part is disposed for the sheathing roof board 7 set on the main house 3 of the general roof part 1. In this case, a roofing plate 9 composed of a metal plate such as a collar steel plate is set through an asphalt roofing 8 on the upper face of the sheathing roof board 6. Furthermore, a solar battery frame 10 is set thereon, and they are fixed by a penetration bolt 11. Thereby it is advantageous on weathering, the number of parts and a working manday are reduced, and waterproofness can be improved. |
