Abstract
A metal and steel framing and substructure system may include a stair assembly system for an elevated metal substructure framing structure. The metal and steel framing and substructure system may include hollow stair stringers formed from single laser-cut steel sheets, each having rises and runs to define integrated steps. The system further includes handrail post brackets spanning between stringers for securing railings. The stair assembly is part of a modular metal substructure framing system comprising galvanized steel ledger tracks, joists, support beams, and vertical posts. The system also includes structural reinforcement components such as post brackets, post bases, and adjustable blocking members to improve load handling and ease of installation.
Claims27
A metal substructure framing system, comprising:
- at least one ledger track configured for attachment to an upright structure;
- at least one track positioned opposite the ledger track;
- a plurality of joists spanning between the ledger track and the at least one track;
- at least one support beam extending underneath and transversely across the plurality of joists, wherein the ledger track, the at least one track, the joists, and each support beam comprises a hollow rectangular cross-section fabricated from galvanized steel;
- a plurality of vertical support posts extending downward from the metal substructure framing system to a foundation or ground surface;
- and
- a stair assembly coupled to at least one end of the metal substructure framing system to provide access between an elevated deck and the foundation or ground surface, the stair assembly comprising:
- a plurality of stair stringers, each stair stringer formed from a laser-cut steel sheet,
- a plurality of rises,
- a plurality of runs, wherein the stair stringers with the plurality of rises and the plurality of runs form a hollow structural member with steps defined by the rises and runs;
- a plurality of stair stringer brackets configured to connect each of the stair stringers to the at least one track or the joist of the metal substructure framing system;
- and
- a pair of stair stringer handrail post brackets configured to attach to a handrail post, wherein the stair stringer handrail post brackets are configured to span between two adjacent stair stringers,
- wherein each stair stringer comprises:
- a first side panel including the plurality of rises welded onto the first side panel,
- a second side panel including the plurality of runs welded onto the second side panel, and
- a bottom panel disposed between the first and second side panels, the bottom panel including an upper edge panel and a lower edge panel, wherein the first and second side panels are folded to form the hollow structural member.
