ABSTRACT:
A modular ramp and landing assembly made from a plurality of similarly sized pre-manufactured concrete filled rectangular panels. The ramp portion is made from the modular panels attached by their shorter sides. A support post with an angularly arranged bracket is placed beneath the corners of adjacent panels to secure them together as well as support them. The landing or horizontal portion of this assembly comprises a similarly sized rectangular panel the long side of which is in abutting relationship with the short side of the end of the ramp. Fastener receivers are equi spaced in duplicate patterns from each corner through the bottom edge of each panel. The size of the panels and the spacing of the fastener receivers are such that minimum support legs and brackets may be utilized in constructing this assembly at a final site.
