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?
 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

BubbleDeck
Reinforced welded mesh
Plastic - balls

Idea & 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
12
Industrialization
of 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

15
A pronounced Reduction
in the Number of Columns
Normal deck
39 columns
BubbleDeck
11 columns
16
Proposal for Building across Railway Trench
1. with prefab concrete elements - 6 storeys
17
2. with BubbleDeck - 7 storeys
18
Production
Plastic and Steel are fit for Industrial Production


Greater precision and better protection of quality
Fast production - Less storage space
19
Carrying out




Less work in situ ;
employment of unskilled labour
Easier and more simple erection
Light and cheap lift equipment
Faster construction time
20
Transportation
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)

Other Techniques / Safety

Moisture
-
condensation-safe construction

Fire
-
fireproof construction

Explosions
-
explosion-safe if carried out as slabcolumn construction (no supporting
walls to suppress the airpressure)

Earthquake
-
safety will benefit significantly alone
from the weight reduction
22
Ecology

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 consumption
The 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.
23
Economy

Less time-consuming

Large savings in resources
(European prices)
replaces
Industrialization
1 kg of plastic at a price of 2-2½ $ US
100 kg of concrete at a price of 4-5 $ US

Savings in subsequent work

Cheaper changes and longer life Flexibility and freedom
Rationalization ;
minimizing the foundation engineering
Represents up to 30 % improvement
of the long-term investment

Use / 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
26
Standard Deck Types
BubbleDeck is produced in 6 standard deck types
The marked standards are recommended

Arguments
Why the Technique must be used





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)

Awards
In 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
