Hvers vegna kúlur?Hvers vegna kúlur?
Holplötur eru með holrými í langáttina... ...og geta því aðeins borið í eina átt Kúlu-holrými gerir plötunni kleift að
bera í tvær áttir... ...eins og staðsteyptar plötur
En vega 30-45% minna

Hvers vegna kúluplötur?Hvers vegna kúluplötur?
Hægt er að auka haflengdir Lengra bil á milli súlna / bita / veggja Hentar vel sem súlu-plötu gólf, án bita Heildarmannvirkið léttist
Hentar vel á jarðskjálftasvæðum

Idea & EffectIdea & Effect
The bubble-technique:
Linking air-bubbles directly together with the reinforcement
The concrete is placed exactly where it provides the greatest effect
Result a distinct minimized construction - up to 100 % increase in effect

IndustrializationIndustrialization
of the in situ Processof the in situ Process
Normal BubbleDeck - bubble lattice, in situ cast
Normal BubbleDeck - 100% prefabricated element(only small units)
Filigree BubbleDeck - bubble-lattice with precast concrete bottom

CCarrying outarrying out
Less work in situ ; employment of unskilled labour
Easier and more simple erection Light and cheap lift equipment Faster construction time
21
TransportationTransportation
The filigree units offer more square metres and less weight per truckload than normal concrete elements
Possible per truckload 200 - 300 m2 bubble-lattice
Example (per truckload – European standards) :
230 mm deck (element-size 3.0 x 7.2 m) : 300 m2 deckvolume : 60 m3
weight : 6-9 ton
22
Other Techniques / SafetyOther Techniques / Safety
Moisture - condensation-safe construction
Fire - fireproof construction
Explosions- explosion-safe if carried out as slab-column construction (no supporting
walls to suppress the airpressure)
Earthquake - safety will benefit significantly alone from the weight reduction
23
EcologyEcology
Savings in resources 1 kg of waste- or recycled plastic replaces 100 kg of concrete.
Yearly savings of 100 mill. tonnes of concrete in Europe.
Less energy consumptionThe use of plastic only requires 1/4 of the energy consumption of the replaced quantity of concrete.
Recycling All components can be used in traditional recycling processes.
24
EconomyEconomy
Less time-consuming Industrialization
Large savings in resources(European prices) 1 kg of plastic at a price of 2-2½ $ US
replaces 100 kg of concrete at a price of 4-5 $ US
Savings in subsequent work Rationalization ; minimizing the foundation engineering
Cheaper changes and longer life Flexibility and freedomRepresents up to 30 % improvementof the long-term investment

Use / QualitiesUse / Qualities
The BubbleDeck can be tailored to meet any purpose
Relevant for the greater part of all building constructions
Obvious to replace any solid deck
Advantageous to use instead of one-way hollow deck and
one-way lightweight concrete
27
Standard Deck TypesStandard Deck Types
BubbleDeck is produced in 6 standard deck types
The marked standards are recommended
Deck thickness (mm) :
170 230 280 340 390 450
Corresponding span (m) :
5-8 7-10 8-12 9-14 10-16 12-18

ArgumentsArguments
Why the Technique must Why the Technique must bbe e usedused
The last stage in a natural process The method has been attempted for the past 100 years The technique is considering the future The future and general technical development are
favourable for the product The deck is the most important structural member (basis)

AwardsAwardsIn 1999 BubbleDeck received two nominations in Holland
The National Building prize
The Industrial Environmental Prize
The Dutch Environmental Authorities have nominated BubbleDeck to the
European Environmental Prize Year 2000
