An occupiable building and a method for constructing an occupiable space in a structural frame building are disclosed. In an embodiment, an occupiable building includes a structural frame defining a footprint of the occupiable building, at least one lower deck structure located within the footprint of the structural frame and supported by the structural frame, at least one upper deck structure located within the footprint of the structural frame and supported by the structural frame, and an interior partition system installed between the lower deck structure and the upper deck structure to define an occupiable space, the occupiable space having a ceiling. The interior partition system includes first king post assemblies, a lower panel, and an upper panel. The lower panel is fastened to the king post assemblies and to the upper panel. The upper panel is fastened to the king post assemblies and to upper panel.

To enhance the positioning accuracy between primary members and auxiliary members without need of latch parts such as rivets, an insertion frame structure includes: a pair of primary members having L-shaped cross-sections and placed with the L shapes facing to each other symmetrically; and several auxiliary members having angular U-shaped cross-sections between the primary members. The primary members and the auxiliary members are joined at latch portions. The latch portions of the primary members have clearance-shaped latch holes. The latch portions of the auxiliary members have convex portions to be inserted into the latch holes. Each latch hole has a clearance with a larger dimension than a plate thickness t of the auxiliary members, and continuously from the clearance, a clearance with a dimension smaller than the plate thickness t of the auxiliary members.

A pre-formed header assembly creates a rough wall opening for a metal door/frame, permitting completion of electrical, ducting, drywall, etc. prior to receiving/installing the door frame. The header is secured to first and second king studs at respective locations positioned beyond a desired door frame location. The header includes four different channels, one of which is utilized at two locations. The first channel has a first length to span between the king studs. The second channel has a second length, and the third channel a third length, which correspond to minimum dimensional requirements for completing the wall. The base of the second and third channels are each fixedly secured to the base of the first channel. The base of the fourth and fifth channels are fixedly secured to the first and second ends of the base of the first channel, respectively, substantially perpendicular thereto, for attachment to the king studs.

A method of installing a panel member on a frame assembly includes the steps of providing a panel member having inner and outer surfaces and providing one or more positioning assemblies on the inner surface of the panel. The positioning assemblies each having an adjustable positioning member adapted to engage a portion of the frame assembly. The method further includes setting the positioning members to determine a registration point for the panel member along the frame assembly. One or more driving assemblies are then provided on the inner surface of the panel, each having a biasing member adapted to engage a portion of the frame assembly to drive the panel member towards the registration point on the frame assembly.

The present invention describes an interlocking metal framing system where two concentric support members slide between each other to enable the support member to form a longer length without using extensions to add the additional length to the support members whether installed as vertical support members for a wall; or as horizontal support members for ceiling support members; or as floor-ceiling support members. The concentric support members have notches together to form a longer support member. The connector can be a clip connecting the two concentric support members together whether installed vertically or horizontally; or by having a longitudinal spacing-bracing member pass through the apertures connecting the perimeter notches of adjacent support members. The perimeter notches interlock the spacing-bracing member to the two concentric support members together eliminating vertical and horizontal movement between the concentric support members as well as the adjacent support members. The apertures are setback from both ends or both concentric support members allowing the additional length to be projected above or below the concentric support members.

The present invention relates to a section bar usable in making a frame for walls as well as a frame structure including this section bar.
