Abstract:

A wall structure for dividing building space includes several different freestanding base panels such as an internally open partition panel, a sound-deadening partition panel, a glass-supporting partition panel, and a doorway-supporting partition panel, and further includes an overhead system comprising a structural expressway construction, a transom subframe, covers for the subframe, and a glass module attachable to the subframe. The structural expressway construction has a torque box bracket for moving support from an inboard location spaced from the vertical side edge of the base panels to the vertical side edge. The transom subframe mounts atop the different base panels, and telescopingly extends into mating engagement with a ceiling channel. The opening between the ceiling channel, the top of the structural expressway construction, and the transom subframes can be selectively covered with either covers or a window subassembly that releasably engages structure on the ceiling channel, the structural expressway construction and the subframes.
