<;P>;PROBLEM TO BE SOLVED: To provide a folded plate roof-greening structure enabling greening on a folded plate roof material by: fixedly placing a plurality of base bar materials to be bridged between respective top parts of folded plate roof materials set up on the roof of a building such as an industrial plant in a parallel condition via connecting fittings; laying a synthetic resin wave plate material on the base bar materials; laying a vacuum-preventive material on each of the protruding parts of the wave plate material; laying a plurality of greening panels on the vacuum-preventive material in a parallel condition; and laying soil such as vegetation flower bed soil on the greening panels to perform greening on the folded plate roof materials, wherein the base bar materials are easily fixed via the connecting fittings. <;P>;SOLUTION: The folded plate roof-greening structure is formed by: fixedly placing a plurality of base bar materials 1 on a folded plate roof material to be bridged between respective top parts W<;SB>;1<;/SB>;of the folded plate roof material W in a parallel condition via connecting fittings 2; laying a wave plate material 3 on the base bar materials; laying a vacuum-preventive material 4 on the protruding parts of the wave plate material; laying a plurality of greening panels 5 on the vacuum-preventive material in a parallel condition; and laying soil D such as vegetation flower bed soil on the greening panels. <;P>;COPYRIGHT: (C)2011,JPO&INPIT
