As shown in the “Ezidek components” section, the ezidek system provides for a series of pre-manufactured, precast light-weight concrete planks, being 250mm wide x 40mm thick. >drawing details

Embedded into these ezidek planks is a layer of trench mesh reinforcement, together with two angled, open-web girder trusses, having a common heavy top-chord bar. It’s this element which gives the ezidek planks their inherent self-spanning strength, together with providing the system with the reinforcing for the beams. >drawing details

By setting the ezidek planks at regular intervals (typically @ 750mm cts.), and by the addition of the styrene void formers, spanning between the planks, and forming the void between the planks to create the insitu beams. Creating in effect a continuous series of insitu formed “parallel t-beams”. >drawing details

The mass of ezidek planks themselves are 17kg/lm. (conc. + steel), and @ 750cts this would be equal to 22.6kg/m2. For the typical beam layout. The total mass of a typically constructed floor 150kg/m2.

The ezidek planks generally, with comfortably span construction loads up to 6.5m. Longer span may be able to be achieved dependant on the particular design parameters.

Ezidek have more recently added a post-tensioned option to their range of building solutions, which will accommodate spans up to 11,000mm. >drawing details

The post-tensioned floor option (as shown ‘above’ employs “double” planks @ 1,000mm cts and the post-tensioning cables run in space between the ‘doubled’ plank/beams. The ezidek system has been used successfully for number of floor levels, at a project at wagga-wagga. >previous jobs

The typical ezidek suspended concrete floor system finishes 270mm thick overall, with the top slab being 90mm thick. >drawing details

The ezidek planks have been tested (simply supported at the ends only ie no intermediate propping points) and comply with the minimum requirements for trafficable formwork. Further the ezidek planks have been tested and approved, in respect to the likely foot traffic point load impact on the beam edges, during on-site assembly.

The ezidek styrene void formers have been similarly tested and approved for use in areas, as trafficable formwork.

The ezidek suspended concrete floor system may be simply supported (ie no intermediate props) to spans not exceeding 3,400mm.

With the addition of a single row of intermediate props, the ezidek suspended concrete floor system may span up to 5,800mm.

For spans exceeding 5,800mm the ezidek suspended concrete floor system requires a double row of intermediate props.

These intermediate props may be removed at 7, 14 or 28 days, dependant of the concrete strength employed.

However fit-out works may proceed on the floor level immediately below the newly poured level the day after, offering considerable savings in project time and costs. >cost savings

Ezidek provides a shallower ‘set-down’ beam, other that the typical beam, for use in creating set-down slabs for either wet-areas, or for external attached balconies. >drawing details

As these ‘set-down’ planks are shallower they are more closely spaced @ 550mm cts. Rather than the typical @ 750mm cts. To provide for the same structural strength. >drawing details

It is also possible use the standard ezidek planks at the closer spacing (550mm) which can extend the spans from the nominal 6,000mm in some cases, dependant on the particular design.

Ezidek are currently considering the manufacture of deeper (higher) beams, to provide for a suspended concrete floor system to satisfy larger spans with-out the need to go to the post-tensioned option.
