Description
Glassfiberarmert sement ("GAS") har vært kjent i mangeGlass fiber reinforced cement ("GAS") has been known in many
år. Hovedfordelene med dette materiale er at det i det minste opprinnelig har stor bøyningsstyrke sammenlignet med betong. På bakgrunn av det store sementinnhold er det meget vannfast, og det kan formes til tynne plater med en tykkelse av størrelsesorden 10 mm med tiltalende overflatestruktur. Materialet kan derfor brukes til for eksempel fremstilling year. The main advantages of this material are that, at least initially, it has great bending strength compared to concrete. Due to the high cement content, it is very waterproof, and it can be formed into thin plates with a thickness of around 10 mm with an attractive surface structure. The material can therefore be used for, for example, manufacturing
av betongkonstruksjoner der permanent forskaling bygges opp av GAS-plater, og betong blir derpå utstøpt der GAS-platene benyttes som en form og opptar betongtrykket mens betongen herdner. Betongen binder til GAS-platene som danner en permanent, vannfast, estetisk tiltalende ytre kledning på den ut-støpte betong. GAS-platene er videre vanligvis utformet slik at de under oppbyggingen er så sterke at de kan oppta vekten av en arbeider, og dette er spesielt fordelaktig når det benyttes GAS-plater ved oppbygging av et brodekke. of concrete structures where permanent formwork is built up from GAS plates, and concrete is then poured where the GAS plates are used as a form and absorb the concrete pressure while the concrete hardens. The concrete binds to the GAS plates which form a permanent, waterproof, aesthetically pleasing outer covering on the poured concrete. Furthermore, the GAS plates are usually designed so that during construction they are so strong that they can absorb the weight of a worker, and this is particularly advantageous when GAS plates are used when building a bridge deck.
GAS har imidlertid også noen ulemper. Under den tid-However, GAS also has some disadvantages. During that time-
lige utvikling av GAS ble alkalisk angrep på glassfibrene et alvorlig problem. Dette har i noen grad blitt forbedret ved bruk av spesialglass, for eksempel glass som har et høyt Zirkoninnholdr Aldring er imidlertid fortsatt et problem. Etterhvert som materialet reduseres vil glassfibrene etter omtrent 2 0 år under normale værforhold ha liten eller ingen innvirkning på materialegenskapene. Fig. 1 på de medfølgende tegninger er et spennings-, forlengelsesdiagram for GAS der fullt opptrukne linjer og prikkede linjer viser oppførselen til ny, respektive aldret GAS og gjelder for strekk. For moderate spenninger vil både ny og aldret GAS virke i hoved-saken som elastiske materialer. Ved større spenninger vil aldret GAS svikte, mens ny GAS ikke gjør det, idet strekk-spenningene i stor utstrekning opptas av glassfibrene. Byggekonstruksjoner blir vanligvis utformet slik at GAS bare blir belastet i det elastiske området. På grunn av ukorrekte konstruksjonsberegninger eller overbelastning av konstruksjonen kan GAS bli utsatt for strekkspenninger over den elastiske grense. Ny GAS kan motstå slike påkjenninger, mens aldret gas vil sprekke. Gjentatte for store belastninger av ny GAS vil bryte ned massen omkring glassfibrene, med det As GAS developed, alkaline attack on the glass fibers became a serious problem. This has been improved to some extent by the use of special glass, for example glass that has a high zirconium content. However, aging is still a problem. As the material is reduced, after approximately 20 years under normal weather conditions, the glass fibers will have little or no effect on the material properties. Fig. 1 of the accompanying drawings is a stress-strain diagram for GAS where solid lines and dotted lines show the behavior of new and aged GAS respectively and apply to tension. For moderate stresses, both new and aged GAS will mainly act as elastic materials. At higher stresses, aged GAS will fail, while new GAS will not, as the tensile stresses are largely absorbed by the glass fibres. Building structures are usually designed so that GAS is only loaded in the elastic region. Due to incorrect construction calculations or overloading of the construction, GAS may be exposed to tensile stresses above the elastic limit. New GAS can withstand such stresses, while aged gas will crack. Repeated heavy loads of new GAS will break down the mass around the glass fibres, with it
resultat at materialet etter kort tid vil fremvise de samme egenskaper som for aldret GAS. En ytterligere ulempe med GAS er at materialet krymper mer enn betong, og unntatt i tilfelle av relativt små elementer eller plater vil det være en tendens til at sprekker oppstår i den svakeste sone. result that after a short time the material will exhibit the same properties as aged GAS. A further disadvantage of GAS is that the material shrinks more than concrete and, except in the case of relatively small elements or plates, there will be a tendency for cracks to occur in the weakest zone.
Kortfattet kan det derfor sies at selv om GAS kan væreIn short, it can therefore be said that although GAS can be
et bidrag ved produksjon av betongkonstruksjoner og til å begynne med kan oppvise vannfasthet og kan gi en estetisk tiltalende ytre kledning på betongen, vil materialet sprekke med tiden og/eller på grunn av for store belastninger, og værfastheten og det estetiske utseendet blir dermed redusert. a contribution in the production of concrete constructions and may initially exhibit water resistance and may provide an aesthetically pleasing external coating on the concrete, the material will crack over time and/or due to excessive loads, and the weather resistance and aesthetic appearance will thus be reduced.
Formålet med foreliggende oppfinnelse er å tilveiebringe et materiale som har de samme fordeler som GAS slik som beskrevet foran, men som i det minste i mindre utstrekning er belemret med de foran beskrevne ulemper. The purpose of the present invention is to provide a material which has the same advantages as GAS as described above, but which is at least to a lesser extent burdened with the disadvantages described above.
Oppfinnelsen tilveiebringer en bygningsplate som bestårThe invention provides a building board which consists of
av eller har et ytre lag av fiberarmert sement og et arrangement av en strekkfast armering innleiret i minst én del av platen eller støtende opp til den fiberarmerte sement, der armeringen omfatter en rekke langstrakte elementer som er festet sammen der de skjærer hverandre, for derved å forsterke materialet i platen over hele den sone hvori armeringen ligger. of or having an outer layer of fiber-reinforced cement and an arrangement of tensile reinforcement embedded in at least one part of the slab or abutting the fiber-reinforced cement, the reinforcement comprising a series of elongate elements fastened together where they intersect, thereby reinforce the material in the slab over the entire zone in which the reinforcement is located.
Armeringsaarangementet omfatter fortrinnsvis et nettverk. Armeringen er fortrinnsvis av stål som kan være galvanisert eller rustfritt, men nettverket kan også være av plastmateriale med høy elastisitetsmodul, f.eks. "Netlon" (varemerke). The reinforcement arrangement preferably comprises a network. The reinforcement is preferably made of steel, which can be galvanized or stainless, but the network can also be made of plastic material with a high modulus of elasticity, e.g. "Netlon" (trademark).
Fibrene i den fiberarmerte sement er fortrinnsvis av glass, men de kan være av ett eller flere av følgende materialer: Glassfibre, mineralfibre, syntetiske fibre med høy elastisitetsmodul og vegetabilske fibre. The fibers in the fibre-reinforced cement are preferably made of glass, but they can be of one or more of the following materials: Glass fibres, mineral fibres, synthetic fibers with a high modulus of elasticity and vegetable fibres.
Ifølge et annet trekk ved foreliggende oppfinnelse erAccording to another feature of the present invention is
det tilveiebrakt en permanent forskalingsplate som omfatter et bygningspanel i samsvar med den første utførelse ifølge oppfinnelsen. it provided a permanent formwork board comprising a building panel in accordance with the first embodiment according to the invention.
Ifølge et tredje trekk ved foreliggende oppfinnelse erAccording to a third feature of the present invention is
det tilveiebrakt en bygningskonstruksjon med en ytre flate som dannes av en permanent forskalingsplate i samsvar med den annen utførelse av foreliggende oppfinnelse og en last-bærende betongdel som forskalingsplaten er permanent bundet til. it provided a building structure with an outer surface formed by a permanent formwork plate in accordance with the second embodiment of the present invention and a load-bearing concrete part to which the formwork plate is permanently bonded.
Når forskalingsplaten på bygningskonstruksjonen blir strekkbelastet vil armeringsarrangementet i platen i stor utstrekning oppta påkjenningene, og spenningsmønstret over platen vil derved bli jevnt eller det vil variere jevnt i stedet for å bli avbrutt på grunn av sprekkdannelser. Fiberarmeringen i sementen vil til gjengjeld forsterke sementen mellom elementene i armeringsarrangementet. Det forefinnes således to armeringsnivåer. For det første sørger det ytterligere armeringsarrangement for en totalarmering av platen, og fiberarmeringen sørger for en lokal armering av sementen inne i det ytterligere eller ekstra armeringsarrangement. When the formwork plate on the building structure is subjected to tensile stress, the reinforcement arrangement in the plate will absorb the stresses to a large extent, and the stress pattern across the plate will thereby become uniform or it will vary evenly instead of being interrupted due to cracking. The fiber reinforcement in the cement will in return reinforce the cement between the elements in the reinforcement arrangement. There are thus two reinforcement levels. Firstly, the additional reinforcement arrangement provides for a total reinforcement of the plate, and the fiber reinforcement provides for a local reinforcement of the cement inside the additional or additional reinforcement arrangement.
Prøver har vist at overbelastning av platene ikke med-fører få og store sprekker, men medfører istedet mikrosprekker innenfor de områder av armeringsarrangementet som har liten skadelig innvirkning på både platenes værmotstandsdyktighet og platenes utseende. Tests have shown that overloading the boards does not lead to few and large cracks, but instead leads to micro-cracks within the areas of the reinforcement arrangement that have little harmful effect on both the boards' weather resistance and the boards' appearance.
I tillegg til å redusere stor oppsprekking på grunn av overbelastning av platene vil armeringsarrangementet også avlaste spenninger som er bygd opp i platen under herding, krymping, fukting og/eller termiske bevegelser. In addition to reducing large cracking due to overloading of the plates, the reinforcement arrangement will also relieve stresses built up in the plate during curing, shrinkage, wetting and/or thermal movements.
Det er selvsagt kjent å benytte stålarmering i betongkonstruksjoner for å øke konstruksjonens evne til å oppta strekkspenninger. Selv om armeringsarrangementet som benyttes i samsvar med oppfinnelsen også har denne effekt, er dette ikke den eneste virkning. Armeringsarrangementet og armeringsfibrene virker sammen og gis spesielle fordeler ved at det er sørget for en totrinns armering som bevirker en forbedring av platens strukturelle integritet over lang tid. It is of course known to use steel reinforcement in concrete structures to increase the structure's ability to absorb tensile stresses. Although the reinforcement arrangement used in accordance with the invention also has this effect, this is not the only effect. The reinforcement arrangement and the reinforcement fibers work together and are given special advantages by the fact that a two-stage reinforcement is provided, which results in an improvement in the structural integrity of the plate over a long period of time.
Det skal nå vises til tegningene, hvor:It must now be shown to the drawings, where:
Fig. 1 på tegningene allerede er beskrevet foran.Fig. 1 of the drawings has already been described above.
Det skal nå gis en beskrivelse i form av et eksempel av en utførelse ifølge oppfinnelsen, idet det vises til de følgende tegninger, hvor: Fig. 2 er et delsnitt av en brodekkeplate ifølge oppfinnelsen. Fig. 3 er et delperspektivriss delvis i utsnitt, av platen på fig. 2, og A description will now be given in the form of an example of an embodiment according to the invention, referring to the following drawings, where: Fig. 2 is a partial section of a bridge deck plate according to the invention. Fig. 3 is a partial perspective view, partly in section, of the plate in fig. 2, and
fig. 4 til 6 viser en ytterligere utførelsesform.fig. 4 to 6 show a further embodiment.
Det skal nå vises fil fig. 2 og 3 der en brodekkeplate 10 har en ytre, nedre flate 12 og en øvre flate 14, hvorpå betongen utstøpes ved fremstillingen av brodekket. Under oppbyggingen av broen vil platen spenne mellom to i avstand fra hverandre anordnede bærere der motstående sidekanter 16 på platen hviler på bærerne. Platen har en rekke flatbunnede V-formede partier 18, og på fig. 2 er det vist to av disse. File fig. should now be displayed. 2 and 3 where a bridge deck plate 10 has an outer, lower surface 12 and an upper surface 14, on which the concrete is poured during the manufacture of the bridge deck. During the build-up of the bridge, the plate will span between two carriers arranged at a distance from each other, where opposite side edges 16 of the plate rest on the carriers. The plate has a number of flat-bottomed V-shaped parts 18, and in fig. 2 two of these are shown.
Platen fremstilles i en hovedsakelig horisontal form som er utformet for å forme den nedre flate på platen. Mørtel sprøytes hovedsakelig vertikalt nedad på formen, sam-tidig som oppkuttede glassfibre med en typisk lengde på 35 mm også sprøytes for å danne en tilfeldig orientert fiberarme-ring i mørtelen. Mørtelen påsprøytes til en tykkelse på omtrent 12 mm på den horisontale del 20 og omtrent 8,5 mm på de hellende partier 22. Den glassfiberarmerte mørtel blir derpå valset for å komprimere denne. The plate is produced in a mainly horizontal shape which is designed to shape the lower surface of the plate. Mortar is sprayed mainly vertically downwards onto the mold, at the same time as chopped glass fibers with a typical length of 35 mm are also sprayed to form a randomly oriented fiber reinforcement ring in the mortar. The mortar is sprayed to a thickness of about 12 mm on the horizontal part 20 and about 8.5 mm on the inclined parts 22. The glass fiber reinforced mortar is then rolled to compact it.
Et armeringsarrangement blir anordnet for hvert av de flatbunnede V-formede deler 18, bestående av et galvanisert stålnettverk 24 med en rekke langsgående elementer 26 og en rekke tversgående elementer 28, som blir sveiset sammen. Hvert element 26, 28 har en diameter på omtrent 2,3 mm og avstanden mellom elementene er omtrent 50 mm. Hvert nettverk 24 er bøyd slik at formen er komplementær til det på-sprøytede GAS-lag, og nettverket blir lagt på og blir i det minste delvis innleiret i GAS-overflaten. En langstrakt stang 30 med trapesformet tverrsnitt av ekspandert polystyren blir derpå opphengt over hvert nettverk, og betong 3 2 som inneholder et super-plastisiseringsmiddel utstøpes i hver renne av GAS, slik at polystyrenstengene 30 innkapsles og at det dannes en øvre plan flate 14 på platen. A reinforcement arrangement is provided for each of the flat-bottomed V-shaped parts 18, consisting of a galvanized steel network 24 with a series of longitudinal members 26 and a series of transverse members 28, which are welded together. Each element 26, 28 has a diameter of approximately 2.3 mm and the distance between the elements is approximately 50 mm. Each web 24 is bent so that the shape is complementary to the sprayed-on GAS layer, and the web is applied and at least partially embedded in the GAS surface. An elongated rod 30 of trapezoidal cross-section of expanded polystyrene is then suspended over each network, and concrete 32 containing a super-plasticizer is poured into each channel of GAS, so that the polystyrene rods 30 are encapsulated and an upper flat surface 14 is formed on the plate .
Platen blir derpå herdet og tatt ut av formen.The plate is then hardened and removed from the mold.
En plate 10 som er fremstilt som foran beskrevet harA plate 10 which is produced as described above has
da en ytre GAS-flate 12 med et armeringsnettverk 24 innleiret i skilleflaten mellom betongen 32 og GAS-lagene. then an outer GAS surface 12 with a reinforcement network 24 embedded in the interface between the concrete 32 and the GAS layers.
Under bruk sammensettes platene som en forskaling, og derpå utstøpes betongen bak platene i kontakt med flaten During use, the plates are put together as a formwork, and then the concrete is poured behind the plates in contact with the surface
14, slik at betongen under herdingen bindes til flaten 14. 14, so that the concrete bonds to the surface 14 during curing.
Det skal nå vises til fig. 4 til 6 på de medfølgende tegninger som viser en lignende brodekkeplate som på figurene 2 og 3, og like deler er blitt betegnet med de samme hen-visningstall. De viktige forskjeller er at armeringsnett-verket 24 bare grenser opp til bunndelene i de flatbunnede V-formede partier 18 og strekker seg ikke opp langs sidene på de V-formede partier, slik som i den tidligere beskrevne konstruksjon. Delene i nettverket 24 er også i sin helhet innleiret i det glassfiberarmerte sementpanel. Ytterligere viktige forskjeller er at polystyrenstengene 30 som benyttes ved støpingen av de øvre flater 14 på platene bare er plassert delvis nede i uttagningene i de V-formede partier 18, slik at det kan støpes et ikke bærende flassfiberarmert sementlag på toppen av stengene 30 til et nivå tett under toppflaten på dekkeplaten. Et fullstendig lukket hulrom er således skapt under stengene 30 i den ferdige konstruksjon. Reference should now be made to fig. 4 to 6 in the accompanying drawings which show a similar bridge cover plate as in figures 2 and 3, and like parts have been designated with the same reference numbers. The important differences are that the reinforcing mesh 24 only adjoins the bottom parts of the flat-bottomed V-shaped parts 18 and does not extend up along the sides of the V-shaped parts, as in the previously described construction. The parts in the network 24 are also entirely embedded in the glass fiber reinforced cement panel. Further important differences are that the polystyrene rods 30 that are used in the casting of the upper surfaces 14 of the plates are only placed partially down in the recesses in the V-shaped parts 18, so that a non-bearing flake fiber-reinforced cement layer can be cast on top of the rods 30 to a level closely below the top surface of the cover plate. A completely closed cavity is thus created under the rods 30 in the finished construction.
