GLIDESTØPT BETONGSTRUKTUR, SAMT FREMGANGSMÅTE OG ANVENDELSE AV EN SLIK BETONGSTRUKTUR. SLIDE CAST CONCRETE STRUCTURE, AS WELL AS PROCEDURE AND USE OF SUCH A CONCRETE STRUCTURE.
Området for den foreliggende oppfinnelse Field of the present invention
Den foreliggende oppfinnelse vedrører betongstrukturer. Mer spesifikt vedrører den foreliggende oppfinnelse glidestøpte betongstrukturer, spesielt strukturer fremstilt av høyfast betong. The present invention relates to concrete structures. More specifically, the present invention relates to slip-cast concrete structures, especially structures made of high-strength concrete.
Bakgrunn for den foreliggende oppfinnelse og kjent teknikk Background of the present invention and prior art
For nærværende blir mange betongstrukturer, slik som betongskaft, typisk støpt ved glidestøping, alternativt betegnet glideforming. Sammenlignet med støping med faste former, er glidestøping veldig fordelaktig, spesielt fra et økonomisk synspunkt, siden arbeidsomfanget i høy grad blir redusert. Overflaten til en glidestøpt betongstruktur inkluderer imidlertid uregelmessigheter, spesielt når det blir anvendt slitasjebestandige betongkvaliteter med høy styrke. Resultatet blir redusert erosjons- og slitasjebestandighet, redusert brukstid og redusert overflatekvalitet, sammenlignet med en struktur som har en glatt overflate, hvilket har tekniske og økonomiske konsekvenser. Utbedring av uregelmessigheter eller erodert eller slitt overflate er ofte veldig kostbart, og kvaliteten blir fremdeles redusert. Støping med faste former for hele eller en del av en betongstruktur er ofte veldig kostbart. Currently, many concrete structures, such as concrete shafts, are typically cast by slip casting, alternatively referred to as slip forming. Compared to casting with fixed molds, slip casting is very advantageous, especially from an economic point of view, since the scope of work is greatly reduced. However, the surface of a slip-cast concrete structure includes irregularities, especially when high-strength wear-resistant concrete grades are used. The result is reduced erosion and wear resistance, reduced service life and reduced surface quality, compared to a structure that has a smooth surface, which has technical and economic consequences. Repairing irregularities or an eroded or worn surface is often very expensive, and the quality is still reduced. Casting with fixed forms for all or part of a concrete structure is often very expensive.
Strukturer som blir anvendt i havområder befengt med drivende overflateis har så langt ikke vært beskyttet i sonen som blir skurt av is med et glidestøpt betongslitasjetillegg, men med en beskyttende stålstruktur, på grunn av de ovennevnte tekniske problemene. For betongstrukturer er slik stålbeskyttelse veldig kostbart, og krever omfattende stillas og ekstra arbeid ved store høyder, og kan ikke være en god teknisk løsning siden integriteten har vært problematisk. Beskyttelse ved å anvende betong har så langt ikke vært mulig for de ønskede pålitelige, langvarige, rimelige og enkle løsningene som industrien søker etter. Relevant bakgrunnsteknikk i forhold til den foreliggende oppfinnelse finnes i patentpublikasjonene US 4355453A, US 2008224022A1, JP 60098006A og DE 102006049037A1. Structures that are used in sea areas infested with drifting surface ice have so far not been protected in the zone that is scoured by ice with a slip-cast concrete wear supplement, but with a protective steel structure, due to the above-mentioned technical problems. For concrete structures, such steel protection is very expensive, and requires extensive scaffolding and extra work at great heights, and cannot be a good technical solution since the integrity has been problematic. Protection by using concrete has so far not been possible for the desired reliable, long-lasting, affordable and simple solutions that the industry is looking for. Relevant background technology in relation to the present invention can be found in the patent publications US 4355453A, US 2008224022A1, JP 60098006A and DE 102006049037A1.
Formålet med den foreliggende oppfinnelse er å tilveiebringe en betongstruktur og en fremgangsmåte for bygging av ovennevnte struktur, som tilveiebringer forbedringer med hensyn til de ovennevnte problemene og ulempene. The purpose of the present invention is to provide a concrete structure and a method for building the above-mentioned structure, which provides improvements with respect to the above-mentioned problems and disadvantages.
Oppsummering av den foreliggende oppfinnelse Summary of the present invention
Den foreliggende oppfinnelse tilveiebringer en glidestøpt betongstruktur, fortrinnsvis en betongstruktur som blir fremstilt av høyfast betong, og hvor minst en del av betongstrukturen blir støpt ved en glidestøping med paneler inne i en glideform, og med paneler som er vendt mot glideformen. Den glidestøpte betongstrukturen er særpreget ved at glideformen sklir på panelene under glidestøpingen, og at panelene ved en ferdigstilt glidestøping blir fjernet fra betongstrukturen for deretter å etterlate seg en glatt, plan og regelmessig hard overflate som et slitasjetillegg på betongstrukturen. The present invention provides a slip-cast concrete structure, preferably a concrete structure that is produced from high-strength concrete, and where at least part of the concrete structure is cast by slip casting with panels inside a slip mold, and with panels facing the slip mold. The slipcast concrete structure is characterized by the fact that the slipform slides on the panels during the slipcasting, and that the panels are removed from the concrete structure when the slipcasting is completed and then leave behind a smooth, flat and regular hard surface as a wear additive on the concrete structure.
Betongstrukturen skal fortrinnsvis anvendes til havs i isbefengte områder og strukturen har en økt tykkelse som et slitasjetillegg i en sone som blir skurt av is som driver på havet. The concrete structure should preferably be used at sea in ice-infested areas and the structure has an increased thickness as a wear supplement in a zone that is scoured by ice that drifts at sea.
Den foreliggende oppfinnelse tilveiebringer også en fremgangsmåte for glidestøping av en betongstruktur, fortrinnsvis en betongstruktur som blir fremstilt av høyfast betong, og hvor minst en del av betongstrukturen blir støpt ved en glidestøping med paneler inne i en glideform, og med paneler som er vendt mot glideformen. Fremgangsmåten særpreges ved glideformen sklir på panelene under glidestøpingen, og at panelene ved en ferdigstilt glidestøping blir fjernet fra betongstrukturen for deretter å etterlate seg en glatt, plan og regelmessig hard overflate som et slitasjetillegg på betongstrukturen. The present invention also provides a method for slip casting of a concrete structure, preferably a concrete structure which is produced from high-strength concrete, and where at least part of the concrete structure is cast by slip casting with panels inside a slip mold, and with panels facing the slip mold . The procedure is characterized by the sliding mold sliding on the panels during the slip casting, and that the panels are removed from the concrete structure when the slip casting is completed and then leave behind a smooth, flat and regularly hard surface as a wear additive on the concrete structure.
Fremgangsmåten er fordelaktig for bygging av en betongstruktur for anvendelse til havs i isbefengte områder, hvor strukturen har en økt tykkelse som et slitasjetillegg i en sone skurt av is som driver på havet. The method is advantageous for the construction of a concrete structure for use at sea in ice-affected areas, where the structure has an increased thickness as a wear supplement in a zone scoured by ice that drifts at sea.
Den foreliggende oppfinnelse tilveiebringer også anvendelse av avtakbare paneler inni en glideform, med panelene vendt mot glideformen, for bygging av en glidestøpt betongstruktur eller en del derav. Anvendelsen er fortrinnsvis for strukturer til havs i isbefengte områder, der strukturen har en økt tykkelse som et slitasjetillegg i en sone skurt av drivis på havet, panelene blir anvendt for bygging av slitasjetillegget ved glidestøping med paneler inni glideformen og panelene blir fjernet fra strukturen etter glidestøpingen. The present invention also provides for the use of removable panels inside a slipform, with the panels facing the slipform, for the construction of a slipcast concrete structure or part thereof. The application is preferably for structures at sea in ice-infested areas, where the structure has an increased thickness as a wear allowance in a zone scoured by drift ice at sea, the panels are used for the construction of the wear allowance by slip casting with panels inside the slip mold and the panels are removed from the structure after slip casting .
Strukturen, fremgangsmåten og anvendelsen ifølge den foreliggende oppfinnelse resulterer overraskende i en glidestøpt betongstruktur eller -del som har en glatt, plan og hard overflate uten uregelmessigheter slik som små sprekker, krakeleringer eller porer, som så langt har vært umulig i fullskalaproduksjon, spesielt når det anvendes harde høyfaste, slitasjebestandige luftrike betongkvaliteter. Uten ønske om å være bundet av teori, antas det at den foreliggende oppfinnelse eliminerer eller reduserer uregelmessigheter, spesielt løftekrakeleringer eller -sprekker, i overflaten til isslitasjetillegget idet glideformen blir løftet oppover, og at slike uregelmessigheter tidligere har vært hovedgrunnen til redusert brukstid og høy slitasjerate. Den tekniske effekten kan være fordelaktig for hvilken som helst betongstruktur, spesielt for betongstrukturer med høystyrkekvalitet som blir utsatt for erosjon eller avsliping eller slitasje av hvilken som helst grunn, for hvilke som helst strukturer for hvilke redusert motstand eller friksjon kan være fordelaktig, og strukturer for hvilke påfølgende behandling kan forenkles. Forringelse, slitasje, aldring, inntrenging av salter og kjemikalier finner sted i prinsippet fra overflaten og innover, for hvilken grunn strukturen, fremgangsmåten og anvendelsen ifølge den foreliggende oppfinnelse kan være fordelaktig siden bedre motstandskraft blir tilveiebrakt. Testing har så langt bekreftet den fordelaktige tekniske effekten; det kan imidlertid ta mange år med vedlikehold og testing for å kunne kvantifisere den tekniske effekten i alle de forskjellige aspektene derav. The structure, method and application of the present invention surprisingly results in a slip-cast concrete structure or part having a smooth, flat and hard surface without irregularities such as small cracks, cracking or pores, which has so far been impossible in full-scale production, especially when hard, high-strength, wear-resistant, air-rich concrete grades are used. Without wishing to be bound by theory, it is believed that the present invention eliminates or reduces irregularities, especially lifting cracks or cracks, in the surface of the ice wear supplement as the sliding mold is lifted upwards, and that such irregularities have previously been the main reason for reduced service life and high wear rate . The engineering effect can be beneficial for any concrete structure, especially for high-strength concrete structures that are subject to erosion or abrading or wear for any reason, for any structures for which reduced resistance or friction may be beneficial, and structures for which subsequent processing can be simplified. Deterioration, wear, ageing, penetration of salts and chemicals takes place in principle from the surface inwards, for which reason the structure, method and application according to the present invention can be advantageous since better resistance is provided. Testing has so far confirmed the beneficial technical effect; however, it may take many years of maintenance and testing to be able to quantify the technical effect in all its various aspects.
Betegnelsen panel betyr i denne sammenheng hvilken som helst i hovedsak todimensjonal struktur som er nyttig for det tilsiktede formålet. Eksempler er plater av ethvert passende materiale slik som metall, polymermateriale, komposittmateriale, betong og keramisk materiale. Paneler inkluderer også hvilke som helst gitter, gitterrist, trådduk eller bikake-liknede plate-liknende strukturer. Panelene har fortrinnsvis en form som er tilpasset stedet de blir anvendt, slik som krummingen til et plattformskaft med rund tverrsnittform. Panelene er anordnet på yttersiden av slitasjetillegget, nærmest glideformen, dvs. som vendt mot glideformen. The term panel in this context means any essentially two-dimensional structure that is useful for the intended purpose. Examples are plates of any suitable material such as metal, polymer material, composite material, concrete and ceramic material. Panels also include any lattice, grating, wire cloth, or honeycomb plate-like structures. The panels preferably have a shape adapted to the place they are used, such as the curvature of a platform shaft with a round cross-sectional shape. The panels are arranged on the outside of the wear allowance, closest to the sliding form, i.e. as facing the sliding form.
Panelene blir fjernet fra strukturen etter glidestøpingen. En glatt indre overflate er foretrukket for panelene. The panels are removed from the structure after slip casting. A smooth inner surface is preferred for the panels.
Slitasjetillegget blir støpt av betong, fortrinnsvis uten stålarmeringsforsterkning unntatt mulige forsterkende fibre som eventuelt kan være stålfibre. En hvilken som helst stålforsterkningsarmering til slitasjetillegget er fortrinnsvis uten elektrisk eller mekanisk kontakt med hovedstålforsterkningsarmeringen. The wear supplement is cast from concrete, preferably without steel reinforcement, except for possible reinforcing fibres, which may possibly be steel fibres. Any steel reinforcement for the wear allowance is preferably without electrical or mechanical contact with the main steel reinforcement.
Lengden av økt tykkelse, det vil si elevasjonsområdet til isslitasjetillegget, omslutter fortrinnsvis området som blir skurt av drivis, som er fra den laveste isdypgangen ved laveste tidevannsnivå til den høyeste forventede istoppen ved det høyeste tidevannsnivået for et betongunderstell. For en flytende betongstruktur, blir tidevannsområdet erstattet av ballastområdet for spesifisering av det nødvendige elevasjonsområdet som har slitasjetillegg. The length of increased thickness, that is, the elevation range of the ice wear allowance, preferably encloses the area scoured by drift ice, which is from the lowest ice depth at the lowest tide level to the highest expected ice crest at the highest tide level for a concrete foundation. For a floating concrete structure, the tidal area is replaced by the ballast area to specify the required elevation area that has wear allowances.
Overgangen fra den ordinære strukturen til strukturen med økt tykkelse er fortrinnsvis gradvis og fortrinnsvis støpt med en innsatsform som panelene er anordnet på. Begge panelene og innsatsformen har fortrinnsvis midler for å bli anordnet eller koblet sammen, slik som med et kilesystem, bolter eller hann-hunn-middel. The transition from the ordinary structure to the structure with increased thickness is preferably gradual and preferably cast with an insert mold on which the panels are arranged. Both panels and the insert preferably have means to be arranged or connected together, such as by a wedge system, bolts or male-female means.
Figurer Figures
Den foreliggende oppfinnelse er illustrert med figurer, av hvilke: The present invention is illustrated with figures, of which:
Figur 1 til 5 illustrerer tverrsnitt gjennom en struktur ifølge den foreliggende oppfinnelse, med et slitasjetillegg. Figures 1 to 5 illustrate cross-sections through a structure according to the present invention, with a wear allowance.
Detaljert beskrivelse Detailed description
Det refereres til Fig. 1, som illustrerer et tverrsnitt gjennom en vegg av en bunnfundament-skaftstruktur 1 som er glidestøpt og som skal bli forsynt med et slitasjetillegg ifølge den foreliggende oppfinnelse. Et glidestøpingsåk 2 og arbeidsplattformer 3 blir løftet oppover samtidig som strukturen blir glidestøpt oppover, på en konvensjonell måte. Reference is made to Fig. 1, which illustrates a cross-section through a wall of a bottom foundation-shaft structure 1 which is slip cast and which is to be provided with a wear supplement according to the present invention. A slide casting yoke 2 and work platforms 3 are lifted upwards at the same time as the structure is slide cast upwards, in a conventional manner.
I Figur 2, har en boltet støtte 4 og en innsatsform eller glideform 5 blitt anordnet på ytterveggen til strukturen. I Figur 3 har det første panelet 6 blitt anordnet på innsatsformen eller glideformen 5. Volumet innenfor panelet blir fylt med betong av en passende kvalitet for slitasjebestandighet og atferd i støpeoperasjonen, hvilken kvalitet kan bli bestemt ved testing. Armeringen er ikke illustrert. Stålarmeringen er fortrinnsvis ikke forlenget inn i slitasjetillegget, men slitasjetillegget kan fortrinnsvis omfatte forsterkende fibre slik som stålfibre, karbonfibre, borfibre eller andre fibre eller keramikk eller annet materiale for økt slitasjebestandighet og/eller styrke. Hovedstrukturarmeringen vil derved ikke bli avdekket etter hvert som erosjonstillegget blir erodert. In Figure 2, a bolted support 4 and an insert mold or sliding mold 5 have been arranged on the outer wall of the structure. In Figure 3, the first panel 6 has been arranged on the insert mold or sliding mold 5. The volume within the panel is filled with concrete of a suitable quality for wear resistance and behavior in the casting operation, which quality can be determined by testing. The reinforcement is not illustrated. The steel reinforcement is preferably not extended into the wear supplement, but the wear supplement may preferably include reinforcing fibers such as steel fibers, carbon fibers, boron fibers or other fibers or ceramics or other material for increased wear resistance and/or strength. The main structural reinforcement will therefore not be exposed as the erosion allowance is eroded.
Figurer 4 og 5 illustrerer hvordan strukturen blir glidestøpt videre, med anordning av paneler suksessivt oppover for å kunne dekke strukturen med slitasjetillegg over den tilsiktede avstanden eller hevingsområdet. Figurene illustrerer også hvordan slitasjetillegget blir terminert ved den øvre enden på en tilsvarende måte som den ble startet i den nedre enden, dvs. med en innsatsform og en boltet støtte. Støttene, innsatsformene og panelene er fortrinnsvis forsynt med midler for å bli koblet sammen, fortrinnsvis på en måte som kan frigjøres. Under glidestøping glir eller sklir glideformen på panelene, ikke på betongen til slitasjetillegget. Følgelig blir betongen til slitasjetillegget ikke utsatt for skjærkrefter med glideformen. Figures 4 and 5 illustrate how the structure is slide cast further, with the arrangement of panels successively upwards to be able to cover the structure with wear allowance over the intended distance or elevation area. The figures also illustrate how the wear allowance is terminated at the upper end in a similar way as it was started at the lower end, i.e. with an insert form and a bolted support. The supports, inserts and panels are preferably provided with means to be connected together, preferably in a releasable manner. During slipcasting, the slipform slides or slips on the panels, not on the concrete of the wear allowance. Consequently, the concrete of the wear supplement is not exposed to shear forces with the sliding form.
Panelene, hvilke som helst innsatsformer og hvilke som helst boltede støtter blir alle fortrinnsvis fjernet etter støpeoperasjonen, og etterlater en glatt, plan, hard og slitasjebestandig regelmessig overflate for slitasjetillegget på strukturen. Omfattende testing har avslørt at en betongkvalitet slik som B70 (CEN: C70/85, ref. ISO 19906) er passende for slitasjetillegg. Testing og utforming har avslørt at en slitasjetilleggstykkelse på 105-122 mm, over et hevingsområde på typisk 6,6 m som omslutter drivisslitasjesonen, for en brukstid på 40 år på skaft til et betongunderstell i isbefengte områder, er passende. The panels, any inserts and any bolted supports are all preferably removed after the molding operation, leaving a smooth, flat, hard and wear-resistant regular surface for the wear allowance on the structure. Extensive testing has revealed that a concrete grade such as B70 (CEN: C70/85, ref. ISO 19906) is suitable for wear additives. Testing and design have revealed that for a 40-year service life on shafts for a concrete substructure in ice-affected areas, a wear surcharge thickness of 105-122 mm, over a typically 6.6 m elevation area enclosing the drift ice wear zone, is appropriate.
Testing har avslørt at innholdet av små sprekker eller revner på en betongoverflate blir dramatisk redusert, og overflaten blir langt glattere, med langt færre uregelmessigheter, ved glidestøping med paneler med glatt panel indre overflate og fjerning av ovennevnte paneler etter støping, ifølge den foreliggende oppfinnelse. Resultatet blir blant annet en forbedret isslitasjebestandighet, en reduksjon i isdannelse på strukturen i seg selv, økt motstandskraft mot gjentatte sykler av frysing og smelting, redusert friksjon og forlenget brukstid for strukturen. Testing has revealed that the content of small cracks or cracks on a concrete surface is dramatically reduced, and the surface becomes far smoother, with far fewer irregularities, when slipcasting with panels with a smooth panel inner surface and removal of the above panels after casting, according to the present invention. The result is improved ice wear resistance, a reduction in ice formation on the structure itself, increased resistance to repeated cycles of freezing and melting, reduced friction and extended service life for the structure.
