Abstract
Et plateformet bygningselement (1) av superlett betong inneholdende minst 50 vol% ekspandert plastmateriale så som EPS, har varierende densitet i sin tykkelsesretning. Eksempelvis har elementet (1) et første sjikt (2) med en densitet på ca 400 kg/m3 og et andre sjikt (3) med en densitet på omtrent 70 kg/m3. Tykkelsen (a) av det første sjikt (2) er noe mindre enn tykkelsen (b) av det andre sjikt (3), idet det første sjikt (2) utgjør den bærende del av bygningselementet, mens det andre sjikt (3) utgjør hovedsakelig en termisk isolerende del av bygningselementet. Det første sjikt (2) kan ha et armeringsnett (5). En fremgangsmåte for fremstilling av bygningselementet er også omtalt.A plate-shaped building element (1) of super-light concrete containing at least 50 vol% of expanded plastic material such as EPS has varying density in its thickness direction. For example, the element (1) has a first layer (2) with a density of about 400 kg / m3 and a second layer (3) with a density of about 70 kg / m3. The thickness (a) of the first layer (2) is somewhat less than the thickness (b) of the second layer (3), the first layer (2) forming the supporting part of the building element, while the second layer (3) is mainly a thermally insulating part of the building element. The first layer (2) may have a reinforcing mesh (5). A method of manufacturing the building element is also discussed.
Description
Foreliggende oppfinnelse vedrører et bygningselement fremstilt av superlett betong inneholdende ekspanderte plastmaterialer i en andel av minst 50 vol%. Slik betong er også blitt kalt polybetong da plastmaterialet ofte består av ekspandert polystyren. The present invention relates to a building element made of super-light concrete containing expanded plastic materials in a proportion of at least 50% by volume. Such concrete has also been called polyconcrete as the plastic material often consists of expanded polystyrene.
Slike bygningselementer benyttes til å fremstille hele hus av polybetong, for eksempel slik det er beskrevet i NO-B-322390, og kan være fremstilt som omhandlet i en NO-A-20070758. Such building elements are used to produce entire houses from polyconcrete, for example as described in NO-B-322390, and can be produced as referred to in NO-A-20070758.
For bærende yttervegger av polybetong har det vært benyttet en veggtykkelse på 25 cm og en densitet på 250 kg/cm for å gi tilstrekkelig bæreevne, samtidig med at varmegjen-nomgangstallet har vært lavt nok til å tilfredsstille dagens forskrifter. Imidlertid kom-mer en ny forskrift for bindingsverkvegger med en tykkelse på 25 cm, hvor varmegjen-nomgangstallet skal være lavere enn det tidligere yttervegger av polybetong har gitt. Foreliggende oppfinnelse skal derfor løse det problem å tilveiebringe en bærende vegg av polybetong som kan tilfredsstille det lavere varmegjennomgangstall, uten at veggtyk-kelsen økes. For load-bearing external walls made of polyconcrete, a wall thickness of 25 cm and a density of 250 kg/cm have been used to provide sufficient load-bearing capacity, while at the same time the heat transfer rate has been low enough to satisfy today's regulations. However, a new regulation is coming for half-timbered walls with a thickness of 25 cm, where the heat transfer rate must be lower than that provided by previous outer walls made of polyconcrete. The present invention will therefore solve the problem of providing a load-bearing wall of polyconcrete which can satisfy the lower heat transfer coefficient, without the wall thickness being increased.
Oppfinnelsens problem løses ved et bygningselement som angitt i krav 1. Fordelaktige utførelser av oppfinnelsen er angitt i de uselvstendige krav 2 til 8. Oppfinnelsen vedrø-rer også en fremgangsmåte som angitt i krav 9, med en fordelaktig utførelse som angitt i krav 10. The problem of the invention is solved by a building element as stated in claim 1. Advantageous embodiments of the invention are stated in the independent claims 2 to 8. The invention also relates to a method as stated in claim 9, with an advantageous embodiment as stated in claim 10.
Til bedre forståelse av oppfinnelsen skal den beskrives nærmere under henvisning til de utførelseseksempler som er vist på vedføyde tegning, hvor For a better understanding of the invention, it shall be described in more detail with reference to the design examples shown in the attached drawing, where
figur 1 viser et tverrsnitt av en første utførelse av et veggelement ifølge oppfinnelsen, og Figure 1 shows a cross-section of a first embodiment of a wall element according to the invention, and
figur 2 viser et snitt i likhet med figur 1 gjennom et andre veggelement ifølge oppfinnelsen. figure 2 shows a section similar to figure 1 through a second wall element according to the invention.
Bygningselementet 1 som er illustrert på figur 1, kan være tenkt benyttet som yttervegg i et hus av polybetong. Elementet har et første sjikt 2 med tykkelse a og et andre sjikt 3 med tykkelse b. Det første sjikt 2 har en densitet i området 350 til 500 kg/m<3>, fortrinnsvis ca 400 kg/m<3>, mens det andre sjiktet 3 har en densitet i området 50 til 80 kg/m<3>, fortrinnsvis ca 70 kg/m<3>. Det første sjiktet 2 kan ha en tykkelse a i området 8 til 12 cm, fortrinnsvis ca 10 cm, mens det andre sjiktet 3 kan ha en tykkelse b i området 12 til 20 cm, fortrinnsvis ca 15 cm. Her danner det første sjikt 2 den bærende del av elementet, mens det andre sjikt 3 har en hovedsakelig isolerende funksjon. The building element 1, which is illustrated in figure 1, can be thought of as being used as an outer wall in a house made of polyconcrete. The element has a first layer 2 with thickness a and a second layer 3 with thickness b. The first layer 2 has a density in the range 350 to 500 kg/m<3>, preferably about 400 kg/m<3>, while the second layer 3 has a density in the range 50 to 80 kg/m<3>, preferably about 70 kg/m<3>. The first layer 2 can have a thickness a in the range 8 to 12 cm, preferably about 10 cm, while the second layer 3 can have a thickness b in the range 12 to 20 cm, preferably about 15 cm. Here, the first layer 2 forms the load-bearing part of the element, while the second layer 3 has a mainly insulating function.
Skillet 4 mellom de to sjikt er angitt med brutt linje for å antyde at det ikke behøver være noe markant skille mellom sjiktene, men at de kan gå over i hverandre slik at elementet danner en tilnærmet monolittisk enhet. Figur 1 viser også at det første sjikt 2 er forsynt med et armeringsnett 5, som fortrinnsvis er anbrakt slik at det forløper gjennom bygningselementets tyngdepunkt (ikke vist). Armeringsnettet 5 kan være egnet til å danne forankring for løftekroker så som vist i NO-A-20070758. The separation 4 between the two layers is indicated by a broken line to suggest that there need not be any marked separation between the layers, but that they can merge into one another so that the element forms an approximately monolithic unit. Figure 1 also shows that the first layer 2 is provided with a reinforcing mesh 5, which is preferably placed so that it runs through the building element's center of gravity (not shown). The reinforcing mesh 5 can be suitable for forming an anchorage for lifting hooks as shown in NO-A-20070758.
Det vil forstås at bygningselementet 1 vist på figur 1 også kan benyttes som dekkeele-ment hvor det første sjikt danner undersiden av elementet. Armeringen 5 kan i dette tilfelle være plassert nærmere sjiktets 2 utside. Hvis elementet benyttes som yttervegg, kan det være hensiktsmessig å forsyne dette med et pusslag på utsiden, eventuelt også på innsiden, og en form for diffusjonssperre vil også være hensiktsmessig på elementets innadvendende side. Pussjiktene kan med fordel være anbrakt i forbindelse med elementets fremstillingsprosess. It will be understood that the building element 1 shown in Figure 1 can also be used as a covering element where the first layer forms the underside of the element. In this case, the reinforcement 5 can be placed closer to the outside of the layer 2. If the element is used as an external wall, it may be appropriate to provide this with a layer of plaster on the outside, possibly also on the inside, and some form of diffusion barrier will also be appropriate on the inward facing side of the element. The plaster layers can advantageously be placed in connection with the element's manufacturing process.
I utførelseseksemplet på figur 2 har elementet 1 et tredje sjikt 6, som også har en relativt høyere densitet enn det mellomliggende sjikt 3. Elementet har videre pussjikt 7 og 8, hvorav det ene kan være kombinert med en dampsperre. Et element av denne type kan være velegnet som innvendig bærevegg. Den absolutte og relative tykkelse av sjiktene 2, 3 og 6 kan varieres alt etter de aktuelle bruksbetingelser. Elementet kan naturligvis også forsynes med armeringsnett der dette måtte være ønskelig. In the design example in Figure 2, the element 1 has a third layer 6, which also has a relatively higher density than the intermediate layer 3. The element also has putty layers 7 and 8, one of which can be combined with a vapor barrier. An element of this type can be suitable as an internal load-bearing wall. The absolute and relative thickness of layers 2, 3 and 6 can be varied according to the relevant conditions of use. The element can of course also be supplied with reinforcing mesh where this is desired.
Fremstilling av bygningselementet ifølge oppfinnelsen vil vanligvis skje ved støping i en hovedsakelig horisontal form med en bredde tilpasset den forønskede takhøyde. Dersom et armeringsnett 5 skal benyttes, blir dette plassert i bunnen av formen på av-standsklosser for å sikre riktig plassering av nettet i det ferdige element. Deretter støpes det første sjikt 2 med høyere densitet til riktig høyde, hvoretter det andre sjiktet 3 med lavere densitet støpes, fortrinnsvis før det første sjikt 2 har rukket å stivne, slik at det skjer enn viss blanding av de to sjikt i overgangsområdet. Skal elementet ha et tredje sjikt 6, støpes dette så snart det andre sjiktet 3 har størknet nok til å bære det tredje sjikt 6. Etter en tilstrekkelig avbinding av sjiktene blir elementet avformet og forsynt med eventuelle pussjikt 7 og 8 før det hensettes til videre herding av bestanddelene. Production of the building element according to the invention will usually take place by casting in a mainly horizontal form with a width adapted to the desired ceiling height. If a reinforcing net 5 is to be used, this is placed at the bottom of the mold on spacer blocks to ensure the correct placement of the net in the finished element. Next, the first layer 2 with a higher density is cast to the correct height, after which the second layer 3 with a lower density is cast, preferably before the first layer 2 has had time to solidify, so that there is some mixing of the two layers in the transition area. If the element is to have a third layer 6, this is cast as soon as the second layer 3 has solidified enough to support the third layer 6. After sufficient bonding of the layers, the element is shaped and provided with any putty layers 7 and 8 before it is set aside for further curing of the constituents.
Den superlette betongen vil vanligvis benytte ekspandert polystyren som isolasjonsma-teriale og vil inneholde et fuktningsmiddel for å få sementen til å hefte til polystyren-kulene, som kan komme både fra ny og resirkulert polystyren. Sementen kan være en portlandsement, en gipsbasert sement eller et annet hensiktsmessig bindemiddel. The super-light concrete will usually use expanded polystyrene as insulation material and will contain a wetting agent to make the cement stick to the polystyrene balls, which can come from both new and recycled polystyrene. The cement can be a portland cement, a gypsum-based cement or another suitable binder.
