Forming of slabs has become a lot more efficient with the introduction of the MevaDec modular slab formwork system.
MevaDec modular formwork offers three forming methods, using the one system, for any suspended slab project. These include FTE, HN and the E method. The drop head system enables early striking to be achieved, typically within 3-4 days (subject to engineer’s approval). MevaDec components can then be cleaned and reused which reduces the amount of slab formwork materials required on site.
3 Forming Methods
Primary & Secondary Beam Method
Primary and secondary beams are situated at the same level. They support the separate plywood or alkus shuttering. The use of drop heads permits early dismantling of the primary and secondary beams, which enables the props to remain behind undisturbed. This forming method can be applied to all floor layouts, even if the floor is not right angled, as the modular system adapts in both directions. This system can be utilised to achieve an off-form finish.
Drop Head - Beam - Panel Method
As with the primary and secondary beam method (HN), the load bearing system is composed of primary beams and drop heads. It supports the ready made panels which have either plywood or alkus as a form facing. The drop head permits the early striking of primary beams and panels. This method achieves a ‘patterned’ finish, due to the layout of panels, with very minimal deflection. If required skimming or patching can assist to ensure a higher class of exposed concrete.
Panels are supported directly at their joints by prop heads – without beams, and whilst productivity levels can be very high, there is no undisturbed propping feature with this style of system. Props can be of lower capacity as spans and or loads are reduced accordingly.
