Description
Fremgangsmåte til fremstilling av et laminert veggelement for bygg. Method for producing a laminated wall element for construction.
Foreliggende oppfinnelse angår en fremgangsmåte til fremstilling av et laminert veggelement for bygg av den type som omfatter to ytre skall som omgir en kjerne av skum. The present invention relates to a method for producing a laminated wall element for buildings of the type comprising two outer shells surrounding a core of foam.
Oppfinnelsen angår likeledes et laminert veggelement som er fremstilt ifølge foreliggende fremgangsmåte samt anord-ninger for utøvelse av denne fremgangsmåte. På klassisk måte og velkjent er et laminert veggelement som i'det vesentlige om-, fatter to ytre skall ofte av laminert glass og harpiks, men kan også være utført-av et hvilket som helst materiale. Disse to skall omgir en kjerne av isolerende materiale som kan være ut-ført av et hvilket som helst materiale som har god isolasjons-kohstant. Laminerte veggelementer av denne type kan omfatte en kjerne som er utført av bl.a. et skum av plastmateriale. Disse kjerner som likeledes er i plateform kan være sprøytet inn i formene, men kan være ferdigfremstilt ved å gå ut fra blokker og deretter limes mellom skallene. The invention also relates to a laminated wall element which is produced according to the present method as well as devices for carrying out this method. In a classic and well-known way, a laminated wall element is essentially two outer shells often made of laminated glass and resin, but can also be made of any material. These two shells surround a core of insulating material which can be made of any material that has a good insulating constant. Laminated wall elements of this type can include a core made of, among other things, a foam of plastic material. These cores, which are also in plate form, can be injected into the molds, but can be ready-made by starting from blocks and then glued between the shells.
Denne fremgangsmåte er imidlertid temmelig lang og kostbar å utføre. Det har vært foreslått en annen fremgangsmåte til fremstilling av laminerte veggelementer, nemlig ved å støpe skummet direkte inn mellom de plater som tjener som skall. I /det materialet som utgjør skummet og har velkjente klebeegen-skaper oppstår det laminerte element samtidig som kjernen dannes ved skumning mellom de to skall. Denne fremgangsmåte som er h'urtig og glatt byr imidlertid på ulemper. Det er i virkelig-heten umulig å kontrollere om skummet fyller fullstendig det indre rom som atskiller de to skall. Hvis dette ikke er til-fellet og hvis det befinner seg luftlommer i det øyeblikk skumningen påbegynnes, vil isolasjonskvaliteten og den mekaniske fasthet for det laminerte element bli mindre. På den annen However, this method is rather long and expensive to carry out. Another method has been proposed for the production of laminated wall elements, namely by casting the foam directly between the plates that serve as shells. In /the material that makes up the foam and has well-known adhesive properties, the laminated element occurs at the same time as the core is formed by foaming between the two shells. However, this method, which is fast and smooth, has disadvantages. In reality, it is impossible to check whether the foam completely fills the inner space that separates the two shells. If this is not the case and if there are air pockets at the moment the foaming begins, the insulation quality and the mechanical strength of the laminated element will be reduced. On the other
side er det vanlig at en skumning av visse plastmaterialer fri-gjør funktighet og frigjør oppløsningsmidler eller restsyrer som ved støpning in situ befinner seg innelåst mellom de to skall og medfører hurtig en ødeleggelse av det laminerte element. Særlig er fenoliske skum som gir god mekaniske egenskaper samt ildfasthet spesielt egnet for bygg, men de har den mangelen at de frigjør vanndamp og syrer under skumningen. Det er således meget vanskelig å la disse skumme in situ. on the other hand, it is common for foaming of certain plastic materials to release moisture and release solvents or residual acids which, when cast in situ, are locked between the two shells and quickly lead to destruction of the laminated element. In particular, phenolic foams, which provide good mechanical properties and fire resistance, are particularly suitable for construction, but they have the disadvantage that they release water vapor and acids during foaming. It is thus very difficult to let these foam in situ.
Formålet med foreliggende oppfinnelse er å fjerne denne ulempe. Fremgangsmåten ifølge foreliggende oppfinnelse karakteriseres ved: 1) at man støper et av skallene slik at det dannes et hulrom i hvilket man sprøyter inn en plastskum etter på forhånd å ha provisorisk -lukket dette volum som man åpner igjen etter skumning for å stenge definitivt etter en tørketid ved å la skummet lime til en plate som danner dét annet skall, 2) etter gjenåpning av hulrommet og før limingen av det annet skall kontrolleres skummet. The purpose of the present invention is to remove this disadvantage. The method according to the present invention is characterized by: 1) that one molds one of the shells so that a cavity is formed into which a plastic foam is injected after having provisionally closed this volume in advance, which is opened again after foaming to close definitively after a drying time by letting the foam stick to a plate that forms the second shell, 2) after reopening the cavity and before gluing the second shell, check the foam.
Det laminerte veggelement som -er fremstilt ifølge oven-nevnte fremgangsmåte karakteriseres ved: 1) et skrog som utgjør det første laminerte skall støpt slik at det dannes et hulrom med en betydelig dybde, 2) en kjerne av plastskum som er sprøytet inn i dette hulrom etter at det har vært lukket med en provisorisk plate, 3) en plate som danner det annet skall limt på skroget og skummet etter at den provisoriske plate er blitt fjernet. The laminated wall element which is produced according to the above-mentioned method is characterized by: 1) a hull which constitutes the first laminated shell molded so that a cavity with a considerable depth is formed, 2) a core of plastic foam which is injected into this cavity after it has been closed with a provisional plate, 3) a plate forming the second shell glued to the hull and foamed after the provisional plate has been removed.
Anordningen for fremstilling av dette veggelement karakteriseres ved at det omfatter i det vesentlige en hul form hvori det støpes et skrog og en stiv plate som tillater at hulrommet lukkes provisorisk for å sprøyte inn skummet. The device for producing this wall element is characterized by the fact that it essentially comprises a hollow form into which a hull and a rigid plate are cast which allows the cavity to be temporarily closed in order to inject the foam.
Andre fordeler og karakteristiske trekk ved oppfinnelsen vil fremgå i den følgende beskrivelse som knytter seg til tegningen som viser: Fig. 1 et tverrsnitt av et ferdig laminert veggelement, Fig. 2 et tverrsnitt som viser støpningen av skroget, Fig. 3 et tverrsnitt som viser innsprøytning av skum, Fig. 4 et tverrsnitt som viser tørking og kontroll, Fig. 5 et tverrsnitt som viser liming av platen som Other advantages and characteristic features of the invention will appear in the following description which is linked to the drawing which shows: Fig. 1 a cross-section of a finished laminated wall element, Fig. 2 a cross-section showing the molding of the hull, Fig. 3 a cross-section showing injection of foam, Fig. 4 a cross-section showing drying and control, Fig. 5 a cross-section showing gluing of the plate as
danner det annet skall.forms the second shell.
På fig. 1 vises i snitt et laminert veggelement ifølge foreliggende oppfinnelse. Dette element omfatter: 1. et skrog eller en panne 1 som utgjør det første skall som er laminert og som er støpt slik at-det dannes et hulrom V med en ikke ubetydelig dybde P, 2. en kjerne 2 av plastskum som er innsprøytet i dette hulrommet V etterat det har vært lukket med en provisorisk plate, som beskrives senere, 3. en plate 3 som danner det annet skall limt til skroget eller pannen 1 og skummet 2 etterat den provisoriske plate er fjernet. In fig. 1 shows a cross section of a laminated wall element according to the present invention. This element comprises: 1. a hull or pan 1 which constitutes the first shell which is laminated and which is molded so that-a cavity V is formed with a not insignificant depth P, 2. a core 2 of plastic foam which is injected into this cavity V after it has been closed with a provisional plate, which will be described later, 3. a plate 3 forming the second shell glued to the hull or pan 1 and the foam 2 after the provisional plate has been removed.
Skroget eller pannen 1 er fortrinnsvis laget av laminert glass og harpiks ved samtidig sprøytning av harpiks og oppkuttede glassfibre. The hull or pan 1 is preferably made of laminated glass and resin by simultaneous spraying of resin and chopped glass fibres.
Dette skrog kunne også vært fremstilt av et hvilketThis hull could also have been produced from which
som helst annet materiale som stemmer overens med de estetiske krav samt de mekaniske og isolerende egenskaper som man krever i bygningen. any other material that complies with the aesthetic requirements as well as the mechanical and insulating properties required in the building.
Kjernen 2 fremstilles av plastskum. Igjen er det mulig å velge blant et stort antall typer skum f.eks. PVC, polyuretan, fenolisk, etc. Fenolisk skum foretrekkes i bygninger på grunn av dets isolasjonsegenskaper, mekanisk fasthet og brannfasthet. The core 2 is made of plastic foam. Again, it is possible to choose from a large number of types of foam, e.g. PVC, polyurethane, phenolic, etc. Phenolic foam is preferred in buildings due to its insulating properties, mechanical strength and fire resistance.
Platen 3 som danner det annet skall kan være fremstilt av et hvilket som helst materiale som går sammen med de krav som spesifiseres for den type bygg som dette laminerte element er bestemt for. Denne plate kan også være fremstilt av tre, metall, spesielle plater, plakogips, lagdelt laminert glass, vitrokeramikk etc. The plate 3 which forms the second shell can be made of any material that goes together with the requirements specified for the type of building for which this laminated element is intended. This plate can also be made of wood, metal, special plates, plaster of paris, layered laminated glass, vitroceramic etc.
Fremgangsmåten og anordningen ifølge foreliggende oppfinnelse tillater fremstilling av laminert veggelement ved å gå ut fr.a fenolskum, idet fjernelse av vanndamp og sure produkter fjernes under skumningen slik som det skal beskrives i forbind-else med fig. 2-5 på tegningen. The method and device according to the present invention allows the production of a laminated wall element by starting from phenolic foam, the removal of water vapor and acidic products being removed during the foaming as will be described in connection with fig. 2-5 in the drawing.
Fig. 2 viser første fase av fremgangsmåten. På denne fig. ser man ved 4 en hul form som er anbragt på platen 5 i en presse hvor man skjeldner bygget 6. Etter å ha penslet det indre av formen med et slippmiddel og deretter en gel-coat sprøytes samtidig ifølge en klassisk fremgangsmåte f.eks. poly-esterharpiks med oppkuttede glassfibre liketil det fås et skrog eller en panne med en med ønsket tykkelse. Hvis denne panne igjen skal fremstilles av et annet materiale enn lagdelt glass-harpiks skal det forstås at støpningen vil være avhengig av materialet. Fig. 2 shows the first phase of the method. In this fig. you see at 4 a hollow mold which is placed on the plate 5 in a press where the building 6 is molded. After brushing the inside of the mold with a release agent and then a gel-coat is sprayed at the same time according to a classic method, e.g. polyester resin with chopped glass fibers until a hull or pan is obtained with one of the desired thickness. If this pan is again to be produced from a material other than layered glass-resin, it must be understood that the casting will depend on the material.
Anvendelse av et skall eller en panne av lagdelt glass-harpiks er imidlertid ikke begrensende. Use of a shell or pan of layered glass-resin is not limiting, however.
Når polyesteren er polymerisert eller under polymeri-seringen anbringes på pannen 1 en stiv plate 7 av tre eller metall med mellomlegning mellom pannen 4 og platen 7 av eti sammenpressbar pakning 8 som er bestemt til å sikre tettheten under skumningen. Tykkelsen av pakningen 8 er overdrevet for å gjøre tegningen klar. Platen 7 er forsynt alt etter dimensjonene for det laminerte element med ett eller flere ihellingshull 9 og luftehull 10 og er på forhånd overtrukket med et slippmiddel e.l. Man senker platen 11 over pressen hvor stempelet er an-tydet med 12 med mellomlegg av bjelker som er skjematisert med 13 som er tilstrekkelig høye for å tillate innsprøytning. Pressen holder platen 7 med sammenpresning av pakningene 8 mot pannen 1. En hensiktsmessig mengde fenolisk harpiks som er tilsatt kata-lysator og som inneholder et skum-middel innsprøytes gjennom en eller flErejtpninger 9. Skummet 2 dannes meget hurtig og fyller volumet V idet luften slipper ut igjennom luftehull 10. Det er nå mulig å fjerne pressen og. fjerne platen 7 som bare har spilt rollen som provisorisk lukning av hulrommetW under skumningen. When the polyester is polymerized or during the polymerization, a rigid plate 7 of wood or metal is placed on the pan 1 with an intermediate layer between the pan 4 and the plate 7 of compressible packing 8 which is intended to ensure tightness during foaming. The thickness of the gasket 8 is exaggerated to make the drawing clear. The plate 7 is provided, depending on the dimensions of the laminated element, with one or more insertion holes 9 and ventilation holes 10 and is previously coated with a release agent or the like. The plate 11 is lowered over the press where the piston is indicated by 12 with interposition of beams schematically shown at 13 which are sufficiently high to allow injection. The press holds the plate 7 with compression of the gaskets 8 against the pan 1. An appropriate amount of phenolic resin to which catalyst has been added and which contains a foaming agent is injected through one or more openings 9. The foam 2 is formed very quickly and fills the volume V as the air escapes out through air hole 10. It is now possible to remove the press and. remove the plate 7 which has only played the role of provisionally closing the cavity W during the foaming.
I det element som er vist på fig. 4 fyller skummet 2 totalt volumet V. In the element shown in fig. 4 the foam 2 fills the total volume V.
Det er således mulig og det er her en vesentlig fordel med fremgangsmåten å kontrollere skummet og sikre at skummet er effektivt ensartet fordelt uten luftlommer som ville kunne inn-virke på fastheten og elementets isolerende egenskaper. It is thus possible and here is a significant advantage of the method to control the foam and ensure that the foam is effectively uniformly distributed without air pockets which could affect the firmness and insulating properties of the element.
I en etterfølgende fase av fremgangsmåten ifølge foreliggende oppfinnelse lar man skummet.tørke i fri luft eller man tørker i tørkerom hvis man vil akselere fremgangsmåten for å fjerne ethvert spor av vanndamp og restsyrer og dette er igjen en annen fordel ved foreliggende fremgangsmåte. In a subsequent phase of the method according to the present invention, the foam is allowed to dry in the open air or dried in a drying room if you want to accelerate the process in order to remove any traces of water vapor and residual acids, and this is again another advantage of the present method.
Fig. 5 viser sluttfasen Jved fremstillingen ifølge frem gangsmåten ifølge oppfinnelsen, nemlig pålimning av det annet skall. Fig. 5 shows the final phase of the production according to the method according to the invention, namely gluing of the second shell.
Etterat formen 4 som inneholder pannen 1 og skummet 2 er fjernet fra tørkerommet anbringes det igjen på platen 5 i pressen og man belegger overflaten på skummet 2 og kantene 14 på pannen 1 med et egnet lim og anbringer platen 15 som utgjør det annet skall og presser for å feste limingen. Fremstillingen er avsluttet og det gjenstår bare å'fjerne det laminerte veggelement fra formen. Etter den ovenstående beskrivelse ses at selv om man anvender en fremgangsmåte for skumning som ligger tett opp til en fremgangsmåte in situ med alle de medfølgende fordeler er ulempene eliminert. After the mold 4 containing the pan 1 and the foam 2 has been removed from the drying room, it is again placed on the plate 5 in the press and the surface of the foam 2 and the edges 14 of the pan 1 are coated with a suitable adhesive and the plate 15 which constitutes the second shell is placed and pressed to attach the gluing. The production is finished and all that remains is to remove the laminated wall element from the form. Following the above description, it can be seen that even if one uses a method for foaming which is close to an in situ method with all the accompanying advantages, the disadvantages are eliminated.
Materialene som kommer på tale i "beskrivelsen i det foregående er bare gitt som eksempler. Formen på det laminerte veggelement er også bare gitt som et eksempel og det er innlys-ende at uten å gå utenfor oppfinnelsens ramme kan denne plate ha en hvilken som helst ønsket form eller f.eks. inneholde støpte avstivere eller ribber i hulrommet V-.før skumningen hvilke ribber vil på kjent måte befinne seg innlemmet i skummet og vil sikre en solid binding mellom de to ytre skall. The materials mentioned in the preceding description are only given as examples. The shape of the laminated wall element is also only given as an example and it is obvious that without going outside the scope of the invention this plate can have any desired shape or, for example, contain molded stiffeners or ribs in the cavity V-.before the foaming, which ribs will be incorporated in the foam in a known manner and will ensure a solid bond between the two outer shells.
