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.

Overhead structures for wall system

A door and doorway construction includes a doorway structure having a lock jamb, a hinge jamb, and a header defining a doorway opening. An adjustable door is constructed to fit mateably into the doorway opening. The doorway structure includes an overhead expressway construction configured to structurally support a weight of the door and further adapted to carry utilities over the doorway opening. The doorway structure is vertically adjustable to align the expressway construction with adjacent wall units, which results in size changes in the doorway opening, and the door is adjustable to define an adjustable vertical height shaped to fill the doorway opening despite the size changes. In one form the door is pivoted to the doorway structure with hinges located above and below the door and at a centerline of the door. In another form, the door is slidably mounted to the doorway structure by a door-supporting boom that includes a trolley rollingly supported by the doorway structure and a downrigger that is rigidly supported on the trolley. The downrigger pivotally supports the door, and the trolley includes a breakaway latch such that the door can be broken away and pivoted outwardly if the door is pressed on with sufficient force. Additional illustrated door embodiments include a solid wood door and a floor-to-ceiling door that incorporate the above features.
