<p>Framework support systems of non-penetrative type for supporting heating and ventilating apparatus and other service and plant apparatus on a roof of a building. The support, for a modular framework system, comprises a planar foot 13 having opposed parallel longitudinal walls 12 defining a longitudinal channel (11, fig 2). The channel is divided by lateral walls 15 into a plurality of framework support areas (20, 21, 22, fig 3) arranged symmetrically in pairs along the channel. Each of at least a first pair of support areas is formed as a pocket (20, 21, 22) having a base and an opening. Each pocket (20, 21, 22) is provided with a projection (32, fig 7) extending from the base, the projection having a generally T- or Y-shaped form having a stem aligned with the longitudinal channel (11) and an arm or arms extending laterally between the parallel longitudinal walls 12. Each pocket is provided with one or more elongate ribs (25) between the base and the opening and extending into the pocket.</p> |
