BubbleDeck International
Build more with less
THOUGHTSFOR THE ENGINEER
A BubbleDeck® slab behaves like a solid slab in every way,
and can be considered as such - incorporated in Eurocodes EN 13747:2005c
EFFECTIVE DESIGN
Easy and effective calculation - can be calculated like a solid slab, by same methods - See Calculations for detailed information
Benefits of the BubbleDeck® technology:
-
Less deflection for long spans
-
Reduced building height and reduced facade costs. Or make space for an extra storey ?
-
Less Excavation - when using sub ground stories
-
Less Foundation
-
Soil conditions becomes a lesser problem
-
No issues with water through connections as BubbleDeck® slab is a seamless floor
-
No issues with water in the voids unlike hollowcore
COMPLY WITH STANDARDS
The BubbleDeck system is fully tested, and can be calculated in the same way as a solid slab, with respect to international (Eurocodes EC2) and national codes as ACI, BS 8110 and AS3660.
Confirms with ISO-standards.
Must always be designed according to national codes.
EFFECTIVE POST-TENSIONING
Both Post Tensioning and Pre Stressed solutions can easily be incorporated in the slab to comply with megaspans.
Compared to its low weight, a BubbleDeck® slab has a relative large height. This is actually increasing the effect of PT and PS.
EXPLOSIVE RESISTANCE
The BubbleDeck® system, the biaxial flat slab system and columns is ideal for structures with high resistance against explosions.
Get rid of heavy facades and rigid walls, suppressing an air pressure which in worst case leads to collapse of the structure.
SEISMIC RESISTANCE
The BubbleDeck® system is probably the most resistant basic construction system towards earthquakes
A simple slab/column system combined with shear walls is regarded as an effective construction method.
The impact of seismic forces imposed on a building is proportional to the horizontal accelerated mass, which has to be absorbed by the stiff vertical structure.
A BubbleDeck® slab with its substantially reduced load, will consequently reduce these forces.
A homogeneous BubbleDeck® slab and column system is without singularities and acts like an elastic membrane, sufficient to transfer horizontal forces to the cores/walls, which effectively take the shear forces.
GREEN ROOFS
Green Roofs are the perfect match to the BubbleDeck® system
Green Roofs are sustainable and can reduce costs,
and have the potential to doubling or tripling the life span of the membrane.
The BubbleDeck technology is the perfect choice for the increased demands of the structural system:
• A roof made with the BubbleDeck® system can carry the increased loads - also over long spans
• The BubbleDeck technology provides a homogenouos slab, which optimizes water tightness
Advantages of Green Roofs
• Reducing storm-water runoff as part of a sustainable drainage systems (SuDS) strategy
• Reducing energy use
• Improving air and water quality
• Lessening the Urban Heat Island Effect (UHIE)
• Climate change mitigation
• Climate change adaptation
• Increasing biodiversity and wildlife
• Reducing sound transfer
• Amenity space
• Roof lifespan increase.
THERMOACTIVE SLABS
The BubbleDeck® system is ideal for making Thermoactive slabs
An energy saving way to heat and/or cool a building, is to use thermoactive slabs.
Thermoactive slabs utilises concrete's mass and ability to adjust room temperature by absorbing and releasing heat.
Water for heating and/or cooling is circulated in embedded plastic pipes in the concrete decks. The temperature of the water is few degrees from the desired room temperature. The system is to a large extent self-regulating, and can be used in connection with a control strategy to obtain extensive energy savings.
Thermal measurements show that sufficient cooling effect is provided, even when acoustic ceilings are used. Thermal comfort can be maintained, and the system can integrate heating and cooling in the same system.
For Heating, savings up to 30 % can be achieved, while for Cooling up to 85 % are possible.
In total, energy savings of 30-50 % are realistic (European conditions).
Piping are placed either at the factory or onsite.
The exact placing (height) of pipes in the deck, depends on the overall heating/cooling effect.
If the primary effect is heating, the pipes are placed relative high.
If cooling is the primary objective, pipes are placed relative low.
