Claim:
A frame for building a ramp that provides wheelchair users ingress and egress to a shower area having sloped floors that direct water to a drain, comprising: said frame having a first flat upwardly inclined surface and an arcuate downwardly inclined surface formed integrally with said first flat upwardly inclined surface to collectively form said ramp; said ramp having a highest point where said first flat upwardly inclined surface meets said arcuate downwardly inclined surface; said first flat upwardly inclined surface having a lowermost end and said arcuate downwardly inclined surface having a lowermost end, said respective lowermost ends being at a common elevation; said frame having a lattice construction to facilitate covering said frame with concrete; said frame secured to a support surface; a first set of screw mounts and associated stabilizing legs formed in said first flat upwardly inclined surface adjacent a lowermost end of said first flat upwardly inclined surface; each screw mount of said first set of screw mounts receiving a screw to secure said frame to said support surface; a second set of screw mounts and associated stabilizing legs formed in said first flat upwardly inclined surface at a predetermined elevation above said first set of screw mounts; a third set of screw mounts and associated stabilizing legs formed in said arcuate downwardly inclined surface at said predetermined elevation; a first cutting line formed in said first flat upwardly inclined surface at a predetermined elevation above said first set of screw mounts; a second cutting line formed in said arcuate downwardly inclined surface at said predetermined elevation; each stabilizing leg associated with said second and third sets of screw mounts abutting said support surface when first and second cuts are made on said first and second cutting lines; each screw mount of said second and third sets of screw mounts receiving a screw to secure said frame to a support surface when said first and second cuts are made on said first and second cutting lines; said ramp extending over an obstacle having a first height when no cuts are made on said first and second cutting lines; said ramp extending over an obstacle having a second height when said first and second cuts are made in said first and second cutting lines; said first height being greater than said second height; and a layer of cementitious material intersecting with said arcuate downwardly inclined surface at any preselected height, said layer of cementitious material sloping downwardly at a predetermined rate as it extends away from said arcuate downwardly inclined surface toward said drain.
