PROBLEM TO BE SOLVED: To provide a greening tile which possesses special functions (strength, heat insulating properties, water retention, drainability and fill) of a burned product, because planting cannot be applied to a tile and the like, conventionally constructed as a roof material for a reinforced concrete structure, though the tile and the like have landscape properties and heat insulating properties. SOLUTION: Mud and stones, and sandy clay are mixed and press-molded by using a special mold, and burnt at 1,000°C. A drain hole 2 is provided in a plane recess 1 subject to the planting, and the tile comprises a curved part 3 which brings about an efficient flow, and a rear curved part 4 similar to the curved part 3. Water overflowing from the rear tile recess 1 is made to flow along a surface layer of a front constructed tile part by make a side surface 5 and a rear rising part higher than the front constructed tile. A drainage groove 6 is provided on the bottom surface of the recess 1, so that the water can be discharged into the drain hole 2. One hole 7 for fixing the tile to the substrate is provided. A screw mounting hole 8 is provided for preventing the tile from being blow away or being shifted downward along a steep slope of a roof. COPYRIGHT: (C)2006,JPO&NCIPI
