Abstract

PROBLEM TO BE SOLVED: To improve workability and preventing damage of building material at the execution so as to restrain generation of corrosion by fitting upper and lower seams of a fixing tool to upper seam parts of upper and lower building materials. SOLUTION: Opposite two sides of metal roofs as building materials are bent inward of a lower surface to form an upper seam part 106. A lower seam 107 at a lower side of a fixing tool 103 is fitted to an upper seam part of the metal roof 101 on the side of eaves edge, and the fixing tool is fixed to a sheathing roof board 105 by machine screw 104. The upper seam part of the roof on the ridge side is fitted to a lower seam part 108 at an upper side of the fixing tool 103. A series of line work is repeated in order to ensure fixation of a plurality of the building materials to a mounting surface with a good execution of work. When a solar cell module is used as a building material, the reliability of power generation can be improved for a long period.
