Kúluplötur Tvívíðar holplötur 1 Byltingarkennd nýjung ! …sem á 10 ára afmæli í ár !!! Byggingargeirinn er frekar svifaseinn… 2 Uppbygging Járnbending í efri brún Loftfylltar plastkúlur Járnbending í neðri brún Steyptur botn 3 Þversnið 4 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 5 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 6 Áhrif kúlnanna Gegnheil plata Notálag (viðbótarálag)( Eiginþungi( Kúluplata Kúluplata Sama þykkt Sama notálag 50 50 1:1 25 40 1.5:1 ) ) Hlutfallstölur (sem % af gegnheilli plötu) Mögulegt notálag Eiginþungi Eiginþungi/mögulegt notálag 25 75 3:1 Samanburður (gegnheil plata með 100 %) Mögulegt notálag Eiginþungi 100 100 200 65 100 50 Nýtni steypunnar 100 300 200 7 Framleiðsla í verksmiðju Járn í efri og neðri brún Kúlur 5 cm þykkur steyptur botn (Filigran) Ekið á byggingarstað 8 Á byggingarstað Hefðbundin flekamót óþörf Einungis stálstoðir og trébitar Einingar hífðar á sinn stað Skeytijárnum komið fyrir Efri hluti plötu steyptur Árangur: Sparar tíma og fjármuni 9 Nútíð og framtíð Sama útlit, en burðarkerfin geta verið ólík Steypt á staðnum Steyptar einingar Kúluplötur? BubbleDeck Reinforced welded mesh Plastic - balls 10 Myndband... 11 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 13 Advantages in Statics Production Carrying out Transportation Safety Ecology Economy Lifetime 14 Superior Statics through Reduced weight of deck Increased strength (relative) Greater span Fewer columns 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) volume weight : : : 300 m2 deck 60 m3 6-9 ton 21 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 24 Lifetime Integrated building parts ( fixed separations ) Independent building parts ( flexible separations ) Years 300 200 30 years Construction + Fill in 15 years Installations 100 300 years 30 years Construction Fill in 15 years Installations Number of new investments during a period of 300 years : 10 10 20 1 10 20 25 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 Deck thickness (mm) : 170 230 280 340 390 450 9-14 10-16 12-18 Corresponding span (m) : 5-8 7-10 8-12 27 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) 28 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 29
