<P>PROBLEM TO BE SOLVED: To provide a construction method capable of surely fixing a photovoltaic power generation panel to a folded-plate roof consisting of thin steel sheets, with full utilization of the rigidity of the folded-plate roof, only by construction from an upper face side of the folded-plate roof. <P>SOLUTION: Long nuts 5 are inserted from an upper face side into a lower face side of a folded-plate roof 1, and bolts 6 are inserted and temporarily screwed to be not perfectly fastened, in a state in which the nuts 5 are suspended to the lower face side of the folded-plate roof 1. Thereafter, the nuts 5 are turned together with the bolts 6 in one direction by further fastening the bolts 6, and thus a part of the outer peripheral surface of each nut 5 abuts on the peripheral wall of the lower face side of the folded-plate roof 1. Thereby, screw connection of the bolts 6 and the nuts 5 is promoted, resulting in perfect fixing thereof, and the direction of the nuts 5 is made uniform when construction is completed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
