PROBLEM TO BE SOLVED: To provide a roof greening structure with a low center of gravity of a vegetation base for reducing forces exerted on a folded-plate and other types of roofs, while securing a large greening area.SOLUTION: A roof greening structure comprises a plurality of fixtures installed on a crest part of a folded-plate roof at a prescribed interval, a plurality of rail materials installed on the fixtures parallelly in the direction normal to a direction of slant of the folded-plate roof, and a rectangular vegetation base installed between the rail materials. The fixture comprises a fitting part for fitting to the folded-plate roof and a bolt part protruded on a top surface of the fitting part. The rail material has a roughly hat-shaped cross section and comprises a crown, a stepped part formed perpendicularly on both sides of the crown, and a flange part formed horizontally on a bottom edge of the stepped part. The bolt part of the fixture is inserted through a bolt insertion hole at the crown part of the rail material while the fitting part of the fixture is enclosed between the stepped parts, and both edges of the vegetation base are placed on the flange part of the parallel rail materials. |
