ABSTRACT A curtain wall for a building structure is provided in which structural members and diaphragms are used to reinforce a relatively light frame such that the number of connections to the building required is reduced to one or two. As a result, problems associated with differential settlement or deflection of the building are minimized, handling and installation is simplified, and the associated costs are reduced. Novel connection means are also provided which enable the individual wall modules of a multimodule building to be aligned and repositioned independent of their adjacent wall modules after all modules have been erected and are supported upon the connections. The curtain wall module comprises a frame having a top and bottom chord and a plurality of transverse studs spaced at intervals along the length of the chords defining a plurality of panels. Exterior cladding including a layer of sheet metal is mounted to the exterior face of the frame strengthening the frame as a stressed diaphragm. In the preferred embodiment the top chord of the frame includes a relatively strong reinforcing beam (such as a square hollow structural section) parallel to and connected to the top chord along the full length of the top chord. The weight of the wall may be supported upon the building by vertically adjustable connectors at two points on the beam. Vertical pins connected to the upper surface of the beam project through the bottom chord web of a like upper adjacent wall module. Diagonally slotted washers engage the pins to allow adjacent modules to be aligned while allowing adjacent modules to deflect vertically relative to each other in an unrestricted fashion.
