An fabricated ramp is provided to construct accurately and easily by installing a flat block, a flat extension block, an inclined block and an inclined extension block on a base material for forming a flat surface, and to drain water actively by forming a step boundary part and obtuse angle corners in the flat block and the flat extension block. An fabricated ramp(100) includes a sectorial flat plate(110) having a step boundary part(112) integrated with a line of a sidewalk(3) for forming an inclined range in the sidewalk and plural flat blocks(111) extended outward and provided with an inner part(111b) integrated with the inner angle of the sidewalk and divided around a central point(111a) and an outer part(111c) formed outside the central point, and an inclined plate(120) inclined, formed outside the flat plate and provided with plural inclined blocks(121) having a step boundary part(121d) integrated with the line of the sidewalk and continuously formed from the step boundary part of the flat plate, an inclined inner part(121a) contacted to the outer part of the flat plate, an inclined outer part(121b) expanded outside the inclined inner part and an upper inclined part(121c) inclined up from the inclined inner part to the inclined outer part. The inner part of 90 to 270‹ is divided, and one or plural flat blocks are expanded outward and formed in the step boundary part. |
