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[edit]
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[edit]
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.
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[edit]
- 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.
- 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.
