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.
Claims12
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 horizontal truss member having a first flange and a second flange which together form an angled cross-sectional shape;
- and
- the horizontal truss member being incorporated into the stairway such that the first flange is in a first dimension and the second flange is in a second dimension, the second flange having higher load requirements than in the first dimension;
- and
- a reinforcing member fixed along the length of the second flange for the purpose of providing increased support in the second dimension.
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 plurality of raised protruding truncated slots formed into the step, each raised protruding truncated slot in the plurality extending substantially from a front of the step to a back of the step;
- a plurality of groups of substantially round apertures formed into the step, each group being separated by at least one slot in the plurality of slots.
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.
