Abstract
Disclosed is an arrangement including a staircase as well as walkway systems. The staircase includes a transitional member, and the walkways incorporate grate supports in order to facilitate the connection to adjacent structures. The arrangement also utilizes angled members which are configured with a reinforced flange existing in a dimension that has higher load requirements than the other flange. A novel step configuration is also disclosed.
Claims20
A metal staircase comprising:
- a plurality of steps, each step in the plurality including downwardly extending sidewalls, and downwardly extending front and back walls,
- a transition member including a first plurality of fastening enabling structures configured to allow for the attachment of the staircase to an adjacent structure at a top of the staircase;
- a second plurality of holes in the transition member, the second plurality of holes configured to mate with a corresponding set of holes in the back wall of a top step of the plurality of steps.
A step for incorporation into a staircase, the step comprising:
- a front wall, a back wall, and a pair of side walls each bent down from a substantially flat body.
A longitudinally-extending angled member used for incorporation into a staircase, the angled member comprising:
- a first flange;
- a second flange;
- the angled member being incorporated into the staircase such that the first flange is in a first dimension and the second flange is in a second dimension, the first dimension encountering disproportionately increased loads relative to the second dimension upon utilization by users of the stairs;
- and
- a reinforcing member fixed to the first flange to counter the increased load requirements in the first dimension.
