  • Modular masonry step and deck assembly
    Patent number: 6295772
    Abstract: The modular masonry step and deck assembly consists of a plurality of like-shaped risers and a plurality of like-shaped treads that enable the assembly to have a variety of shapes, sizes and heights to provide a custom fit to a variety of buildings, mobile homes or trailers. The risers are dry stacked in a multi-tier, multi-column, multi-row arrangement to form a base of the assembly. An inwardly expanding groove is formed in each corner of each riser. When aligned flush with adjacent risers and dry stacked one atop the other in a stacked bond arrangement, the groves form a continuous vertical channel. A semi-flexible locking key is formed inside the channel to secure the risers together, but accommodate movements caused by the freezing and thawing of the ground. Four differently shaped treads are used to form the walking surface of the step and deck assembly. Each tread shape is used to form a specific portion of the walking surface.
