Description

Bygningselement Building element

Foreliggende oppfinnelse vedrører et bygningselement fremstilt av lettbetong, spesielt superlett betong inneholdende ekspandert plastmateriale i en andel av minst 50 volumprosent. Slik betong er også blitt kalt polybetong, idet plastmaterialet ofte består av ekspandert polystyren. The present invention relates to a building element made of lightweight concrete, especially super lightweight concrete containing expanded plastic material in a proportion of at least 50 percent by volume. Such concrete has also been called polyconcrete, as the plastic material often consists of expanded polystyrene.

Slike bygningselementer har vært benyttet til å fremstille hele hus av polybetong, idet prefabrikkerte veggelementer reises på et fundament, fortrinnsvis også bestående av utstøpt polybetong, og festes til hverandre, hvorpå huset forsynes med et tak av lignende bygningselementer. Such building elements have been used to produce entire houses from polyconcrete, as prefabricated wall elements are erected on a foundation, preferably also consisting of poured polyconcrete, and attached to each other, after which the house is provided with a roof of similar building elements.

På grunn av polybetongens meget lave egenvekt kan veggelementene gjøres så store at de alene kan utgjøre en hel veggflate. Veggelementene løftes på plass ved hjelp av stropper som føres ned under veggelementets underkant eller festes til U-formede løftesko som omklamrer elementets underkant. Ingen armering av veggelementet er nødvendig, og derfor kan åpninger for vinduer og dører lett skjæres ut av veggen etter monteringen på fundamentet. For dette formål har søkeren utviklet et spesielt stativ for føring av en vanlig motorsag for nøyaktig utskjæring av åpningene. Stativet er omhandlet i norsk patentsøknad 20062925. Due to polyconcrete's very low specific weight, the wall elements can be made so large that they alone can form an entire wall surface. The wall elements are lifted into place with the help of straps that are passed under the lower edge of the wall element or attached to U-shaped lifting shoes that clamp around the lower edge of the element. No reinforcement of the wall element is necessary, and therefore openings for windows and doors can be easily cut out of the wall after installation on the foundation. For this purpose, the applicant has developed a special stand for guiding an ordinary chainsaw for precise cutting of the openings. The stand is covered in Norwegian patent application 20062925.

Annerledes stiller det seg med takelementer og andre dekkeelementer av polybetong. Disse må forsynes med armering for å tåle nyttelast og tilfredsstille bestemmelser om maksimal tillatt nedbøyning. I vanlig betong vil strekkarmering alene gjøre nytten, men da polybetongen har liten trykkstyrke, vanligvis av størrelsesorden 100 N/cm<2>, antok man at det også ville være nødvendig å legge inn trykkarmering for å gi strekkarmering en tilstrekkelig motstand. Imidlertid viste det seg meget overraskende at bruk av trykkarmering i tillegg til strekkarmeringen førte til en større nedbøyning enn med strekkarmeringen alene. Dekkeelementene blir derfor fremstilt med bare strekkarmering. The situation is different with roof elements and other covering elements made of polyconcrete. These must be provided with reinforcement to withstand the payload and satisfy provisions on maximum permissible deflection. In ordinary concrete, tension reinforcement alone will do the trick, but as the polyconcrete has a low compressive strength, usually of the order of 100 N/cm<2>, it was assumed that it would also be necessary to add compression reinforcement to give the tension reinforcement sufficient resistance. However, it turned out very surprisingly that the use of compression reinforcement in addition to the tension reinforcement led to a greater deflection than with the tension reinforcement alone. The cover elements are therefore produced with only tension reinforcement.

Søkeren har funnet at det ville være hensiktsmessig å kunne løfte bygningselementene uten bruk av Løftestropper. Dette gjelder både ved avforming av elementet og ved senere håndtering på byggeplassen. Når det gjelder bygningselementer av vanlig betong, er det kjent å forsyne veggelementer med løfteorganer i form av for eksempel ører, vaierløkker eller festemuttere for demonterbare øyekroker. Således er det fra EP 0392610 A2 kjent et veggelement av vanlig betong med innstøpte isolasjonsplater, hvor betongen er armert og veggelementet ved sin øvre kant er forsynt med to kanaljernformede muttere for senere innfesting av øyebolter, hvor kanaljernmutterne er forankret i betongen ved hjelp av påsveisede, korte bøyler av armeringsjern eller lignende. The applicant has found that it would be appropriate to be able to lift the building elements without the use of lifting straps. This applies both to the design of the element and to subsequent handling on the construction site. When it comes to building elements made of ordinary concrete, it is known to provide wall elements with lifting means in the form of, for example, lugs, cable loops or fastening nuts for demountable eye hooks. Thus, from EP 0392610 A2, a wall element made of ordinary concrete with cast-in insulation plates is known, where the concrete is reinforced and the wall element is provided at its upper edge with two channel iron-shaped nuts for later attachment of eyebolts, where the channel iron nuts are anchored in the concrete by means of welded, short hoops of rebar or similar.

En slik løftekonstruksjon ville ha for dårlig feste i et veggelement av polybetong på grunn av dennes mye lavere styrke. Heller ikke andre tidligere kjente festeorganer for veggelementer av betong har vist seg å kunne gi tilstrekkelig uttrekksstyrke til å gjøre nytten i et element av polybetong. Such a lifting construction would have too poor a hold in a wall element made of polyconcrete due to its much lower strength. Nor have other previously known fastening means for concrete wall elements been shown to be able to provide sufficient pull-out strength to be useful in a polyconcrete element.

For å løse dette problem har søkeren gått til det skritt å innlemme et ellers unødvendig armeringsnett i veggelementet, for så å forankre løfteorganene i armeringsnettet på en slik måte at den nødvendige uttrekksstyrke oppnås. For takelementer har søkeren utnyttet den samme idé og festet løfteorganer til armeringen, for på denne måte å kunne forsyne takelementet med tilsvarende Løfteanordninger. In order to solve this problem, the applicant has gone to the step of incorporating an otherwise unnecessary reinforcing mesh into the wall element, then anchoring the lifting members in the reinforcing mesh in such a way that the required pull-out strength is achieved. For roof elements, the applicant has used the same idea and attached lifting devices to the reinforcement, in order to be able to supply the roof element with corresponding lifting devices in this way.

Oppfinnelsen er nærmere definert i krav 1, og fordelaktige utførelser er definert i de uselvstendige krav. The invention is further defined in claim 1, and advantageous embodiments are defined in the independent claims.

Til bedre forståelse av oppfinnelsen skal den beskrives i det følgende under henvisning til de utførelseseksempler som er skjematisk vist på vedføyde tegninger, hvor figur 1 viser skjematisk et perspektivisk bilde av et veggelement ifølge oppfinnelsen, og figur 2 viser på lignende måte et takelement ifølge oppfinnelsen. 1 begge utførelseseksemplene er polybetongen angitt som delvis gjennomsiktig for å vise plasseringen av armeringsnettet og løfteorganene. For a better understanding of the invention, it shall be described in the following with reference to the embodiment examples which are schematically shown in the attached drawings, where Figure 1 schematically shows a perspective view of a wall element according to the invention, and Figure 2 similarly shows a roof element according to the invention. 1 in both design examples, the polyconcrete is indicated as partially transparent to show the location of the reinforcing mesh and the lifting devices.

Veggelementet 1 på figur 1 kan for eksempel ha en tykkelse på 25 cm og har et armeringsnett 2 anbrakt midt i elementet. Nettet kan ha betegnelsen Kl31, med en jerndiameter på 5 mm og en senteravstand på 150 mm. The wall element 1 in Figure 1 can, for example, have a thickness of 25 cm and has a reinforcing mesh 2 placed in the middle of the element. The net may have the designation Kl31, with an iron diameter of 5 mm and a center distance of 150 mm.

Veggelementet har to løfteorganer 3, som her består av en jernstang som er bøyd i vinkel til en avrundet V-form, hvor de frie ender er bøyd til en krok 4, som fra undersiden av armeringsnettet er hektet opp rundt et langsgående jern i armeringsnettet. Løfteorganet, som for eksempel kan bestå av 10 mm kamstål, blir før støpingen av veggelementet sveiset fast til armeringsnettet 2, ikke bare for at det skal holde seg på plass under støpingen, men også for å overføre løftekreftene til en så stor del av armeringsnettet 2 som mulig. The wall element has two lifting members 3, which here consist of an iron rod which is bent at an angle into a rounded V-shape, where the free ends are bent into a hook 4, which from the underside of the reinforcing mesh is hooked up around a longitudinal iron in the reinforcing mesh. The lifting member, which can for example consist of 10 mm combed steel, is welded to the reinforcing mesh 2 before the casting of the wall element, not only so that it stays in place during casting, but also to transfer the lifting forces to such a large part of the reinforcing mesh 2 as possible.

Bøyen 5 av løfteorganene 3 vil ligge i flukt med det som blir det ferdige veggelements toppside. For at et passende parti av bøyen 5 skal kunne blottlegges for feste av løftekroker eller lignende, blir det før støpingen av veggelementet plassert en passende avskjermning rundt bøyen 5 for å holde støpemassen tilbake. En slik avskjermning kan være en plastkopp med en sliss i bunnen som træs et stykke nedover bøyen 5. The bend 5 of the lifting members 3 will lie flush with what will be the finished wall element's top side. In order for a suitable part of the buoy 5 to be exposed for the attachment of lifting hooks or the like, before the casting of the wall element, a suitable screen is placed around the buoy 5 to hold back the molding compound. Such a shield can be a plastic cup with a slot in the bottom which is threaded a little way down the buoy 5.

Det er viktig at løfteorganene 3 blir liggende på undersiden av armeringsnettet 2 ved støpingen. Derved hindres de i å bli dratt ut av betongen dersom de skulle bli benyttet ved avforming av elementet uten at formen først er brakt i vertikal stilling. It is important that the lifting members 3 lie on the underside of the reinforcing mesh 2 during casting. Thereby, they are prevented from being pulled out of the concrete if they were to be used when shaping the element without the form having first been brought into a vertical position.

Eksempelet på figur 1 viser et sentrert armeringsnett 2, men det vil forstås at dersom bruksbetingelsene gjør det ønskelig, kan dette erstattes med to armeringsnett beliggende nær hver sin side av veggelementet. I dette tilfellet blir løfteorganenes kroker 4 å feste til hvert sitt nett, og de må bøyes slik at de frie ender av krokene peker innover i veggelementet 1. De to nett kan være av samme type og dimensjon som det enkle, sentriske nett nevnt ovenfor. The example in Figure 1 shows a centered reinforcing mesh 2, but it will be understood that if the conditions of use make it desirable, this can be replaced with two reinforcing meshes located close to each side of the wall element. In this case, the lifting members' hooks 4 must be attached to each net, and they must be bent so that the free ends of the hooks point inwards into the wall element 1. The two nets can be of the same type and dimension as the simple, centric net mentioned above.

Det vil ses at krokene 4 av løfteorganene 3 er hektet rundt det langsgående jern som er nr. fem regnet fra elementets toppside. Generelt tar oppfinnelsen sikte på å anbringe krokene i en dybde fra toppsiden som er minst lik to ganger veggelementets tykkelse, for derved å sikre en betryggende forankring av løfteorganene 3. It will be seen that the hooks 4 of the lifting members 3 are hooked around the longitudinal iron which is number five counted from the top side of the element. In general, the invention aims to place the hooks at a depth from the top side that is at least twice the thickness of the wall element, thereby ensuring a reliable anchoring of the lifting members 3.

Takelementet 6 vist på figur 2 har strekkarmering i form av et nett 7, som i de fleste tilfeller vil være betydelig sterkere enn nettet benyttet i veggelementet 1. Armeringsnettet 7 er bøyd opp langs elementets kortsider for å forbedre forankringen av de langsgående, mest påkjente jern og øke skjærstyrken i elementets opplagringsområder. Tykkelsen av takelementet 6 vil kunne variere avhengig av dets lengde. Eksempelvis vil et 6 meter langt element kunne ha en tykkelse på 40 cm. The roof element 6 shown in figure 2 has tensile reinforcement in the form of a net 7, which in most cases will be significantly stronger than the net used in the wall element 1. The reinforcing net 7 is bent up along the short sides of the element to improve the anchoring of the longitudinal, most stressed irons and increase the shear strength in the element's storage areas. The thickness of the roof element 6 may vary depending on its length. For example, a 6 meter long element could have a thickness of 40 cm.

Takelementet 6 har fire løfteorganer 8 anordnet symmetrisk både om den langsgående og tversgående sentralakse. Løfteorganene 8 har form av en langstrakt U, hvor en relativt lengre del 9 av U-ens ben, via en passende krummet overgang, er bøyd i rett vinkel med en relativt kortere del 10 av U-en som inneholder dennes basisparti 11. Den relativt lengre del 9 av Løfteorganets 8 ben er anbrakt under den langsgående del av strekkarmeringen 7 og krysser tre av jernene i denne. The roof element 6 has four lifting members 8 arranged symmetrically both about the longitudinal and transverse central axis. The lifting members 8 have the shape of an elongated U, where a relatively longer part 9 of the leg of the U, via a suitable curved transition, is bent at right angles with a relatively shorter part 10 of the U which contains its base part 11. The relatively the longer part 9 of the Liftorganet's 8 leg is placed under the longitudinal part of the tensile reinforcement 7 and crosses three of the irons in this.

Også i dette tilfellet vil det være fordelaktig å sveise løfteorganene 8 fast til armeringen 7. Videre vil det være fordelaktig at de tversgående armeringsjernene 12 ligger over de langsgående armeringsjernene 13. Also in this case, it would be advantageous to weld the lifting members 8 firmly to the reinforcement 7. Furthermore, it would be advantageous for the transverse reinforcing bars 12 to lie above the longitudinal reinforcing bars 13.

Det vil forstås at det ved støping av takelementet 6 sørges for at toppartiet 11 av Løfteorganene 8 forblir frilagt, selv om deres overkant ligger på samme nivå som takelementets 6 toppflate. Videre vil det forstås at den relativt lengre del av U-ens ben 9 ikke behøver å være parallelle, men gjerne kan divergere på lignende måte som veggelementets løfteorganer 3. Man kan også tenke seg at hvis armeringens dimensjonering og innfesting tillater det, kan man temporært frilegge armeringen lokalt og benytte denne direkte som løfteorgan. Dette gjelder også veggelementet på tilsvarende måte. It will be understood that when casting the roof element 6 it is ensured that the top part 11 of the Lifting Organs 8 remains exposed, even if their upper edge is at the same level as the top surface of the roof element 6. Furthermore, it will be understood that the relatively longer part of the U's legs 9 need not be parallel, but can preferably diverge in a similar way to the wall element's lifting means 3. One can also imagine that if the dimensioning and fixing of the reinforcement allows it, one can temporarily expose the reinforcement locally and use this directly as a lifting device. This also applies to the wall element in a similar way.

Selv om oppfinnelsen har vært beskrevet ovenfor i forbindelse med to kontrete utførelseseksempler, vil det være klart for fagmannen at oppfinnelsen vil kunne varieres og modifiseres innenfor rammen av de påfølgende patentkrav. Although the invention has been described above in connection with two counter-embodiment examples, it will be clear to the person skilled in the art that the invention will be able to be varied and modified within the framework of the subsequent patent claims.
