Build like everybody is watching!
Cobute is committed to building the best structures with its precast concrete shutters for slabs, beams, stairs and edge ribs. The only question is - is it going to be your structure?
Cobute Panel-deck
“Custom designed to your Engineer’s specifications”
Cobute Panel-deck consists of lattice frame, lightweight reinforced concrete panels and polystyrene blocks.
Panel-deck is the evolution of the rib and panel slab, to ensure fast and high-quality installation of the decking while retaining the full benefits of a monolithic structure.
As in the case of the traditional Cobute decking, Panel-deck consists of three elements: lightweight reinforced concrete panels, longitudinal stiffening lattice frames and polystyrene blocks.
Technical Details
The flat concrete panels are 1m wide, with a thickness ranging from 50 to 70 mm and can be manufactured in any length up to a maximum of 12m. The longitudinal slab reinforcement is custom designed by a Consulting Engineer for each project.
Why Polystyrene?
The use of polystyrene has many structural and insulating benefits
The use of polystyrene void formers bring a wide range of benefits among which large variation in slab thicknesses, without any undue increase in the in situ concrete thickness. It also contributes to the light weight of the slab (97 kg/ m² dead load) and the easy distribution of services. Thermal insulation is guaranteed; a 250 mm thick slab reports an excellent R value of 0.4889, which helps reduce the energy consumption of the structure.
The manufacturing process allows for the tailoring of the panels to specific requests such as the casting in of downlighter boxes or the creation of penetrations in the panels.
Panel-deck installation requires the use of a crane
Propping
The Panel-deck is cast at the factory and delivered to site.The panels are lifted into place with the use of a crane and the in situ concrete is poured after the additional steel (specified by the Engineer) and mesh have been positioned. Propping is required at 1.2m centres and can be removed 14 days after casting of the in situ concrete or as specified by the Engineer.
Precast Panel-deck by Cobute is Fire resistant. A 230 mm thick slab has a fire resistance of 150 minutes. It has a smooth off-steel shutter finish, with chamfered edges along its length.
Panel-deck caters for a wide range of load requirements, as the position (centre-to-centre) of lattices can be adjusted to suit design specifications. Applications go from roofs to walls, suspended floors and permanent shutters for roads and bridges. The system can also be used as a permanent
shutter for two-way spanning concrete slabs.
