Abstract:
A modular masonry step and deck assembly for constructing on the ground adjacent an elevated entrance of a building having a specific usable area and the entrance being a specific height above the ground, said modular masonry step and deck assembly comprising:a plurality of similar-shaped risers, each riser having substantially planar top and bottom surfaces, and front, rear and opposed side walls with outer surfaces, each outer surface being at substantially a right angle to its two adjacent wall outer surfaces, and each of said risers having uniform height, width and depth dimensions;a plurality of tiers including a ground tier and a predetermined number of stacked tiers, said stacked tiers including an upper tier, said ground tier including a predetermined number of rows and columns of said risers, each stacked tier being placed atop an immediately lower tier, each tier having a front column and an end row, each of said stacked tiers having one fewer column than and being staggered from said front column of its said immediately lower tier, each of said front columns having a corner riser and a remaining front portion including at least one more of said risers, said end row of said upper tier including said corner riser and a remaining side portion including at least one more of said risers, said upper tier having an interior portion of said risers, said plurality of tiers forming at least one common planar surface adapted for alignment with the building;a plurality of similar-shaped corner treads, similar-shaped front treads, similar-shaped side treads, and similar-shaped inner treads, each of said treads having a uniform height dimension, substantially planar top and bottom surfaces, and front, rear and opposed side wall surfaces, each of said wall surfaces being at substantially a right angle to its adjacent wall surfaces, each of said corner treads having uniform width and depth dimensions that are greater than said respective width and depth dimensions of said risers, each of said front treads having a uniform width dimension that is equal to said width dimension of said risers and a uniform depth dimension that is equal to said depth dimension of said corner treads, each of said side treads having a uniform width dimension that is equal to said width dimension of said corner treads and a depth dimension that is equal to said depth dimension of said risers, and each of said inner treads having uniform width and depth dimensions that are equal to said respective width and depth dimensions of said risers;a plurality of steps formed by said front columns and said corner and front treads, one of said corner treads being placed on each of said corner risers, and one of said front treads being placed on each of said risers in said remaining front portions, and said corner and front treads forming a continuous lip around each of said steps;a deck formed by said side and inner treads, one of said side treads being placed on each of said risers forming said remaining side portions of said upper tier, and one of said inner treads being placed on each of said risers forming said interior portion of said upper tier, said corner, front and side treads forming a continuous lip around said step and deck of said upper tier; and,wherein said number of tiers, rows and columns of said risers are varied to provide a custom fit to the size of the usable areas and height of the entrance of the building.
