Panel fixings

Panels can be either top hung from the structure or supported from their base. Nibs projecting from the back of the panel transmit the load to the structure by means of a mortar bed. Panels can then be restrained either by dowel bars or by angle cleats, both of which must be fixed so as to permit vertical movements arising from the deformation of the structure or movement of the panels. Various combinations of dowel and cleat fixings are shown in Fig. 1.30. Contractors often prefer cleat fixings at the top with dowel or cleat fixings at the bottom (types a and b) because this facilitates quick erection; however; building inspectors sometimes prefer panels to overhang the slab, as in theory should the fixing fail the panel would fall inwards under its own weight and wind loading.
