Concrete panel roof or ceiling support structure - has edge bars on slab bonded to transverse reinforcing inlays in joint gaps subsequently filled with concrete

摘要

Rectangular-plan reinforced-concrete panels, prefabricated in pairs, have continuous transverse reinforcing inlays, with an intervening lengthways gap where they are bent over into a folded structure, with two of these forming a V-shaped channel. Between two adjacent folded structures (5) the channel is covered by a reinforced-concrete slab (7) with connecting bars (10) protruding on both longitudinal edges. The bars grip between the transverse reinforcing inlays (4), in the gap (3) area, and are cast into an entity with them. This provides increased load bearing capacity, and/or the possibility of wider spans.
