Voided Biaxial Slab - Applications

Applications

The Biaxial BubbleDeck® can be implemented in three versions according to degree of prefabrication:

• “Reinforcement modules”: Comprising prefabricated “bubble-lattice” sandwich elements to be placed on traditional formwork. Building time is reduced compared to conventional on site construction.

Suitable for the majority of new-build projects, also suspended ground floor slabs and alteration / refurbishing projects.

• “Filigree elements”: Where the bottom side of the 'bubble-lattice' unit is furnished with a pre-cast concrete layer which replaces the horizontal part of the formwork on the building site, optimizing both building time and quality by prefabrication.

Acts directly like a seamless ceiling. Suitable for the majority of new-build projects.

• “Finished elements”: Finished panels, complete precast slab elements. These can be used for limited areas such as balconies or staircases.

The BubbleDeck technology can benefit most buildings. However, as it is a biaxial deck technology, the use will focus on biaxial slab designs.

Functional applicability: Residential living, offices, utility and industrial buildings. Used in offices, apartments, villas, hotels, schools, parking, hospitals, laboratories and factories.

As a consequence of the reduced load, it is possible to achieve larger spans than a solid slab. Depending of the design, spans of 20 to 40 times the deck height are possible. Cantilevers can be made 10 times the deck height. By incorporating PT cables, these spans can be further enhanced.

The effect of PT cables in a BubbleDeck slab is enhanced, because of the relative high deck height compared to the moment strength. This combination could seem like the perfect match for several applications.
