The present staircase includes a permanent framing made of metallic stringers, one of which being typically secured to a half-timbering. vertically extending step supports are secured along the stringers and each include upper and front flanges adapted to be secured respectively to a tread and to a riser of each step of the staircase. A temporary staircase may be easily obtained with the present kit for use during construction, wherein a number of L-shaped steel step units are laid onto the step supports to form a successive series of alternating risers and treads. Then, these L-shaped steel units can be removed and replaced by finished steps of various configurations. If the staircase has an exposed side, a finishing stringer is provided thereat to conceal the structural metallic stringer. Various support systems, including corner posts and brackets, are provided for supporting various horizontal and vertical structural components of the framework of the staircase, including when the staircase is L-shaped or U-shaped thereby including a turn in the staircase with flaring steps, and also possibly a landing. |
