摘要

The system may include a joist rim (20) that has at least one attachment tab (30) integrally formed therein to facilitate attachment of a joist (40) to the joist rim (20). Reinforcing ribs (38) are preferably provided adjacent the attachment tabs (30) for providing desired structural integrity to the attachment tab connection. The system may also include a C-shaped joist (40) that has a plurality of oval-shaped openings (50) therein to enable components such as ducts, wires, piping, etc, to pass therethrough. The joists (40) may also be provided with a plurality of mounting holes (62) that are adapted to accommodate wire retaining members for supporting insulation between respective joists. The system may also include pre-formed blocking members(80) that are sized to extend between adjacent joists (40) and be attached thereto to provide lateral support to the joists.
