Abstract
A modular stairway assembled from a stringer having a relatively planar, flat top, an initial step module fixed adjacent a lower end of the stringer, and several intermediate step modules attached to the stringer. The initial step module includes an upper edge, and a portion of the first intermediate step module bears against the upper edge of the initial step module. A method of constructing the stairway includes the steps of placing the stringer in position relative to a structure, anchoring the initial step module adjacent a lower end of the stringer to define an initial riser and tread for the stairway, and to define an initial stop. A first of the intermediate step modules is supported on the module-supporting top of the stringer, and then a downward force is placed on the intermediate step module, thereby forcing the module along the top of the stringer into firm contact with the initial stop of the initial step module and insuring proper alignment of the intermediate step module to the initial step module. The intermediate step module is anchored to the stringer.
