Description
Den foreliggende oppfinnelse angår en fremgangsmåte til forsterkning av kanter av bygningsplater omfattende en kjerne av stivnet gips innesluttet mellom dekkark av papir eller lignende. The present invention relates to a method for strengthening the edges of building boards comprising a core of hardened plaster enclosed between cover sheets of paper or the like.
I lette vegg- og himlingskonstruksjoner er det ofte Ønskelig In light wall and ceiling constructions, it is often desirable
å feste de paneler eller plater som konstruksjonen består av, ved hjelp av såkalte skjulte festemetoder for å skaffe en overflate som ikke er skjemmet av synlige festemidler. En måte til oppnåelse av en slik befestigelse er å anvende plater eller fliser med spor, noter, furer eller innsnitt i kantene som flenser eller fjærer på stenderverk kan passe inn i for å bære platene. Anordning av slike innsnitt i kantene av gipsplater medfører imidlertid problemer som følge av den relativt lave styrke av platenes gipskjerne. to fasten the panels or boards of which the construction is made up, using so-called hidden fastening methods in order to obtain a surface that is not marred by visible fasteners. One way of achieving such a fastening is to use plates or tiles with grooves, grooves, furrows or incisions in the edges into which flanges or springs on studwork can fit to support the plates. Arrangement of such incisions in the edges of gypsum boards, however, causes problems due to the relatively low strength of the boards' gypsum core.
Disse problemer foreligger enten notene dannes ved tildannelse av innsnitt i kantene av på forhånd fremstilte paneler eller ved formgivning av panelene under støpingen eller formgivningen. Videre bør kantene være forsterket slik at de ikke så lett skades ved transport og anvendelse. These problems exist whether the grooves are formed by creating incisions in the edges of previously produced panels or by shaping the panels during casting or shaping. Furthermore, the edges should be reinforced so that they are not easily damaged during transport and use.
For å gi den ønskede beskyttelse av kantene må forsterknings-strimler med et egnet profil bestå av hovedsakelig stivt materiale, f.eks. metall, og dette gjør det vanskelig å innlemme slike strimler i platekantene. Videre er det meget ønskelig at den herdede gipskjerne i den ferdige plate er fullstendig innesluttet av dekkarkene (bortsett fra de kappede ender av tilskårne plater), idet dette hindrer inntrengning av fuktighet og mulighet for skade på platekantene som følge av slik fuktighet. To provide the desired protection of the edges, reinforcement strips with a suitable profile must consist of mainly rigid material, e.g. metal, and this makes it difficult to incorporate such strips into the plate edges. Furthermore, it is highly desirable that the hardened plaster core in the finished board is completely enclosed by the cover sheets (apart from the cut ends of cut-to-size boards), as this prevents the ingress of moisture and the possibility of damage to the board edges as a result of such moisture.
Oppfinnelsen løser begge disse problemer i en kontinuerlig prosess hvor kjernen av platen skjæres tilbake,mens dekkarkene tillates å beholde sin fulle, opprinnelige bredde. Forsterkningsstrimmelen blir deretter påsatt og kantene av dekkarkene blir bøyd The invention solves both of these problems in a continuous process where the core of the plate is cut back, while the cover sheets are allowed to retain their full, original width. The reinforcement strip is then applied and the edges of the cover sheets are bent
ned og bundet til strimmelen. down and tied to the strip.
Fremgangsmåten ifølge oppfinnelsen er såledeskarakterisertved at kjernen av en allerede fremstilt gipsplate skjæres tilbake langs minst én kant, mens dekkarkene levnes i utragende stilling fra kanten, at en forsterkningsstrimmel med ønsket profil føres til anlegg mot den tilbakeskårne kant, og at kanten av dekkarket brettes ned mot overflaten av strimmelen og festes til denne. Bredden av strimmelen er fortrinnsvis lik tykkelsen av kjernen ved kanten. The method according to the invention is thus characterized by the fact that the core of an already produced plasterboard is cut back along at least one edge, while the cover sheets are left in a protruding position from the edge, that a reinforcement strip with the desired profile is brought into contact with the cut-back edge, and that the edge of the cover sheet is folded down towards surface of the strip and attached to it. The width of the strip is preferably equal to the thickness of the core at the edge.
Forsterkningsstrimmelen kan være flat eller profilert, og The reinforcement strip can be flat or profiled, and
når den har fremspring i retning mot kjernen, blir kjernens kanter tilskåret med motsvarende profil. En foretrukket utførelsesform av fremgangsmåten ifølge oppfinnelsen er< såledeskarakterisertwhen it has protrusions in the direction of the core, the edges of the core are cut to a corresponding profile. A preferred embodiment of the method according to the invention is thus characterized
ved at der i kanten av kjernen skjæres et spor, at en forsterkningsstrimmel i form av et kanalelement med kantflenser som strekker seg sideveis i planet for platekanten, presses inn i sporet, og at de nedbrettede kanter av dekkarkene festes til flensene. in that a groove is cut in the edge of the core, that a reinforcing strip in the form of a channel element with edge flanges that extends laterally in the plane of the plate edge is pressed into the groove, and that the folded edges of the cover sheets are attached to the flanges.
Fremgangsmåten skaffer en bygningsplate med en kjerne av stivnet gips innesluttet mellom dekkark av papir eller lignende og en forsterkningsstrimmel langs minst én kant, idet minst de tilgrensende kanter av dekkarkene er brettet over i det minste en del av en utadvendende flate av forsterkningsstrimmelen og festet til denne ved klebning. Forsterkningsstrimmelen har fortrinnsvis en slik bredde at den ender ved kantene eller skuldrene av platen (bortsett fra eventuelle dekkark). Det er ikke nødvendig å anvende klebemiddel for å binde forsterkningsstrimmelen til kjernen, men slikt klebemiddel kan anvendes hvis det er ønskelig å danne en ytterligere binding. Forsterkningsstrimmelen kan fremstilles slik at den passer nøyaktig inn i kanten av kjernen, ved at kanten og strimmelen profileres på egnet måte, og de fastklebede dekkark bidrar til å holde strimmelen på plass og beskytte den mot utvendige mekaniske midler som ville kunne bringe den ut av stilling. The method provides a building board with a core of hardened plaster enclosed between cover sheets of paper or the like and a reinforcement strip along at least one edge, at least the adjacent edges of the cover sheets being folded over at least part of an outward facing surface of the reinforcement strip and attached to this by gluing. The reinforcement strip preferably has such a width that it ends at the edges or shoulders of the plate (apart from any cover sheets). It is not necessary to use adhesive to bond the reinforcement strip to the core, but such adhesive may be used if it is desired to form an additional bond. The reinforcement strip can be made to fit exactly into the edge of the core, by suitably profiling the edge and the strip, and the glued cover sheets help to hold the strip in place and protect it from external mechanical means that could move it out of position .
Forsterkningsstrimmelen kan bestå av et hvilket som helst materiale med den styrke som er nødvendig for å skaffe forsterkningen av kanten,■f.eks. metall eller plast. I de foretrukne paneler blir imidlertid forsterkningsstrimmelen dannet'av rustbeskyttet metallplate. Når forsterkningsstrimmelen har et egnet ikke lukket profil, kan den fremstilles kontinuerlig ved valsing av en metallstrimmel i den bedrift hvor den kontinuerlige fremstilling av panelelementene foregår, og deretter kontinuerlig påføres kantene av panelelementene når disse føres frem gjennom anlegget. The reinforcing strip may consist of any material of the strength necessary to provide the reinforcement of the edge, e.g. metal or plastic. In the preferred panels, however, the reinforcement strip is formed of rust-protected metal sheet. When the reinforcement strip has a suitable non-closed profile, it can be produced continuously by rolling a metal strip in the company where the continuous production of the panel elements takes place, and then continuously applied to the edges of the panel elements as these are brought forward through the plant.
De forsterkede kanter som fås ved fremgangsmåten ifølge oppfinnelsen, kan tildannes på plater med avsmalnende kanter såvel som på de vanligere plater med rettvinklede kanter• Videre vil skjæringen av platekantene gi en riktigere kant enn den som oppnås ved den opprinnelige støping av papirdekkede plater på vanlige gips-plåtemaskiner, slik at det blir mulig å oppnå en finere eller nøyakti-gere fuge mellom naboplater eller -fliser i en veggkonstruksjon. The reinforced edges obtained by the method according to the invention can be formed on boards with tapering edges as well as on the more common boards with right-angled edges • Furthermore, the cutting of the board edges will give a more correct edge than that obtained by the original molding of paper-covered boards on ordinary plaster sheet metal machines, so that it becomes possible to achieve a finer or more accurate joint between neighboring sheets or tiles in a wall construction.
Enda finere fuger kan oppnåes i vegg- eller himlingskonstruksjoner hvor steget av en bærestøtte står i inngrep med notene i to nabopaneler med notkanter, hvis kanten eller skulderen av hver plate skjæres lenger tilbake på den side som skal utgjøre baksiden av noten, enn kanten eller skulderen på forsiden. Dette tillater at steget av bærestøtten får plass mellom nabopanelelementer samtidig som disses forkanter bringes til fullstendig anlegg mot hinannen, så der fåes en skjøt eller fuge som er nesten usynlig når den betraktes på avstand, og som når det gjelder plater hvis kanter er rettvinklede, kan tapet-seres eller dekoreres direkte uten dekking eller fylling av skjøten med strimler eller skjøtemasse. Even finer joints can be obtained in wall or ceiling constructions where the step of a supporting support engages the grooves of two neighboring panels with grooved edges, if the edge or shoulder of each panel is cut further back on the side to form the back of the groove than the edge or shoulder on the front page. This allows the step of the supporting support to be accommodated between neighboring panel elements at the same time as their front edges are brought into complete contact with each other, so that a joint or joint is obtained which is almost invisible when viewed from a distance, and which, in the case of panels whose edges are right-angled, can wallpapered or decorated directly without covering or filling the joint with strips or joint compound.
Oppfinnelsen vil nå bli nærmere beskrevet under henvisning The invention will now be described in more detail under reference
til tegningen, som viser fire forskjellige utførelsesformer av panelelementer som kan fremstilles i henhold til den foreliggende oppfinnelse, i forskjellige stadier under fremstillingen. to the drawing, which shows four different embodiments of panel elements that can be manufactured according to the present invention, at different stages during manufacture.
Fig. 1 viser en kant av en gipsplate 10 med en kjerne 11 og forside- og baksidedekkark 12 resp. 13• Platen kan være en vanlig gipsplate som er fremstilt på vanlig måte, og dekkarkene kan f.eks. bestå av papir. Når det gjelder paneler med en dekorativ overflate kan de i det minste på forsiden belegges med et plastmateriale som bindes til platens papiroverflate. Ved 14 er der antydet et skjære-verktøy som når det bringes i berøring med kanten av platen 10, skjærer tilbake kjernen 11 for å danne en not eller et innsnitt 15 med avrundet bunn eller indre hjørner og skuldre 16 som vist på figuren. Skjæreverktøyet kan omfatte et midtblad 17 for tildannelse av noten og sideblad 18 til bortskjæring av kjernen langs innerflaten av dekkarkene. Disse blader kan være av sirkelsagtypen, og ytterligere blad 19 som kan dreie seg sammen med sagbladene, kan være anordnet for å rense skuldrene av den skårne kant til den ønskede dybde. Fig. 1 shows an edge of a plasterboard 10 with a core 11 and front and back cover sheets 12 or 13• The plate can be a regular gypsum board that is produced in the usual way, and the cover sheets can be e.g. consist of paper. In the case of panels with a decorative surface, they can be coated, at least on the front, with a plastic material that is bonded to the paper surface of the plate. At 14 there is indicated a cutting tool which, when brought into contact with the edge of the plate 10, cuts back the core 11 to form a groove or notch 15 with rounded bottom or inner corners and shoulders 16 as shown in the figure. The cutting tool can comprise a central blade 17 for forming the groove and side blade 18 for cutting away the core along the inner surface of the cover sheets. These blades may be of the circular saw type, and additional blades 19 which may rotate with the saw blades may be provided to clean the shoulders of the cut edge to the desired depth.
På fig. 2 er platen vist under fremføring forbi førings-plater 21 som holder de utragende kanter 22 av dekkarkene fra hinannen samtidig som et på forhånd tildannet kanal- eller not-element 23 med flenser langs begge kanter og avrundet bunn eller indre hjørner skyves på plass i noten 15 av et egnet verktøy .2*1. Kanalelementet 23 kan fremstilles kontinuerlig ved valsing av en metallstrimmel, og dette kan utføres samtidig i det samme anlegg, idet det nettopp valsede element føres kontinuerlig inn i sporet i kanten av den kontinuerlige fremførte plate. In fig. 2, the plate is shown being advanced past guide plates 21 which hold the projecting edges 22 of the cover sheets from one another at the same time as a previously formed channel or groove element 23 with flanges along both edges and rounded bottom or inner corners is pushed into place in the groove 15 of a suitable tool .2*1. The channel element 23 can be produced continuously by rolling a metal strip, and this can be carried out at the same time in the same plant, the just rolled element being fed continuously into the groove at the edge of the continuously advanced plate.
Fig. '3 viser det neste trinn i fremstillingen hvor et klebemiddel, f.eks. et varmsmeltende klebemiddel (hot melt adhesive), på-føres innerflaten av de utragende kanter 22 av dekkarkene ved hjelp av dyser eller andre egnede påføringsorganer 31• Denne figur viser også at forsterkningselementet 23 har en slik utstrekning i side- eller bredderetningen at det ender i flukt med kantene av kjernen på innersiden av dekkarkene 22. Fig. 3 shows the next step in the production where an adhesive, e.g. a hot melt adhesive is applied to the inner surface of the projecting edges 22 of the cover sheets by means of nozzles or other suitable application means 31 • This figure also shows that the reinforcement element 23 has such an extent in the lateral or width direction that it ends in flush with the edges of the core on the inside of the cover sheets 22.
Tilslutt blir kantene 22 av arkene ved hjelp av egnede føringsskinner brettet inn mot flensene av kanal- eller notelementet 23 for å klebes til dette og valset på plass av en sluttbehandlingsvalse kl som vist på fig. k. Finally, the edges 22 of the sheets with the help of suitable guide rails are folded in against the flanges of the channel or groove element 23 to be glued to this and rolled into place by a finishing roller kl as shown in fig. k.
Skjønt der på tegningen er vist en plate med rettvinklede kanter og utformet med en notkant med skuldre av samme bredde på hver side av noten, vil det for fagfolk uten videre være forståelig at egnede modifikasjoner av skjærebladene 17, 18 og 19 kan skaffe en skulder som er skåret tilbake eller avfaset i større grad enn den annen. Dette vil i såfall være skulderen 16a (fig. k) hvis overflaten 12 er på forsiden av platen. Det vil også være klart at en lignende forsterkende notkant kan dannes på plater med avsmalnende kanter. Although the drawing shows a plate with right-angled edges and formed with a groove edge with shoulders of equal width on each side of the groove, it will be readily understood by those skilled in the art that suitable modifications of the cutting blades 17, 18 and 19 can provide a shoulder which is cut back or chamfered to a greater extent than the other. In that case, this will be the shoulder 16a (fig. k) if the surface 12 is on the front of the plate. It will also be clear that a similar reinforcing groove edge can be formed on plates with tapered edges.
Hvis profilet av den fremre flens av elementet 23 modifiseres og noten og skulderen i kjernen modifiseres tilsvarende, kan videre platen gis en kant med en hvilken som helst ønsket profil,f.eks. for det tilfelle at fugen mellom naboplater skal utgjøre et trekk ved den sammensatte konstruksjon. If the profile of the front flange of the element 23 is modified and the groove and shoulder in the core are modified accordingly, the plate can further be given an edge with any desired profile, e.g. in the event that the joint between neighboring panels is to constitute a feature of the composite construction.
Fig. 5 viser én kant av en gipsplate-10 med en kjerne 11 og dekkark 12 og 13 på henholdsvis forsiden og baksiden. Skjæreverktøyet, som kan være av sirkelsagtypen, er vist ved lå. Når kantene av platene . 10 bringes i berøring med skjæreverktøyet, vil dette skjære- tilbake kanten av kjernen 11 inntil dekkarkene som vist ved 15,.for å danne to dype falser. Skjæreverktøyet kan også omfatte et■midtre blad 17 for tilbakeskjæring av kjernen mellom falsene... Fig. 5 shows one edge of a plasterboard 10 with a core 11 and cover sheets 12 and 13 on the front and back respectively. The cutting tool, which may be of the circular saw type, is shown at When the edges of the plates. 10 is brought into contact with the cutting tool, this will cut back the edge of the core 11 up to the cover sheets as shown at 15, to form two deep folds. The cutting tool may also comprise a central blade 17 for cutting back the core between the folds...
Fig. 6 viser at flensene 25 av et på forhånd tildannet kanalelement 2 3 som kan bestå av valset metall, kan skyves på plass over kanten av platen mellom de tilskårne flater og dekkarkene ved hjelp av et egnet verktøy 24. De utragende kanter av dekkarkene kan her-under holdes tilbake av føringsskinner som på fig. 2. Fig. 6 shows that the flanges 25 of a previously formed channel element 2 3 which may consist of rolled metal can be pushed into place over the edge of the plate between the cut surfaces and the cover sheets with the help of a suitable tool 24. The projecting edges of the cover sheets can below is held back by guide rails as in fig. 2.
