Holedeck (hˈo͡ʊldɛk) is a type of reinforced concrete structure characterised by lateral perforations, which reduce the volume of concrete and allow the passage of installations.

Design[editar]

The design is based on the principles of the lightened, triangulated bird bone structure.

For the construction of the transverse windows, special removable and reusable truncated cone-shaped moulds are used, which are extracted laterally after the concrete has been poured. This technology was patented and developed by the Spanish architect Alberto Alarcón García.

Configurations[editar]

Biderctional system

The structure has two configurations: unidirectional or in orthogonal or triangular grid. For lattice arrangements the structural behaviour and calculation is similar to that of other waffle slabs.

One-way system

In the case of the one-way system, the layout is similar to a conventional in-situ joist and beam truss. The shear of the structure is solved by the literal application of the tie rod model and is calculated in a similar way to concrete structures without perforations.

These structures are suitable for spans of between six and twenty-two metres, making them an optimal choice for the construction of sustainable concrete structures.

Features[editar]

  • Lower consumption of concrete and steel. The compression layer has a minimum thickness of between 8 and 12 cm, strictly sized according to structural fire regulations. The joists are spaced between 1 and 3 metres apart, thus making structural use of this compression layer, lightened by the perforations. For further optimisation they can be post-tensioned.
  • Minimisation of concrete and steel consumption making it possible to reduce the embedded carbon footprint by around 50% compared to a lightened slab.[1]​
  • Possible elimination of false ceilings and raised floors. Installation and maintenance of facilities is facilitated.
  • Possible reduction in the height of the building by integrating the installations and the structure in the same thickness.
  • Good geometry for thermal activation due to the high surface area in contact with the air and a smaller volume of concrete than a slab.
