Description

Foreliggende oppfinnelse angår en fasadebekledning av plater for bolighus, fabrikkbygninger og andre enheter. The present invention relates to a facade cladding made of panels for residential buildings, factory buildings and other units.

Oppfinnelsen angår mere bestemt fasadebekledninger omfattende fasadeelementer samt festeanordninger for disse. The invention relates more specifically to facade coverings comprising facade elements as well as fastening devices for these.

Pasadebekledninger av den ovennevnte art er tid-ligere kjent i en mengde utførelser og dimensjoner. Facade coverings of the above-mentioned kind are currently known in a multitude of designs and dimensions.

Kjente fasadebekledninger som er oppbygd av et antall elementer, ofte i en dimensjon av omkring 0,5 -Imi kvadrat, er imidlertid utført slik at det mellom hvert element er spor eller opphøyninger, ved hvilke festeanordninger finnes. De kjente fasadeelementene er således ikke utført slik at det kan oppnås en vesentlig helt plan fasade. However, known facade coverings which are made up of a number of elements, often in a dimension of around 0.5-Imi square, are designed so that between each element there are grooves or elevations, where fastening devices are found. The known facade elements are thus not designed so that an essentially completely flat facade can be achieved.

I den senere tid er det blitt en etterspørsel In recent times it has become a demand

etter fasadeelementer ved hjelp av hvilke en pusset fasade kan etterlignes. Kjente fasadebekledninger kan ikke etter-ligne en pusset fasade, da nevnte spor eller opphøyninger umuliggjør oppbygging av en i det vesentlige helt plan fasade. according to facade elements with the help of which a plastered facade can be imitated. Known facade coverings cannot imitate a plastered facade, as said grooves or elevations make it impossible to build an essentially completely flat facade.

Foreliggende oppfinnelse angår en fasadebekledning av den art som angitt i hovedkravets ingress og med de sær-trekk som angis i hovedkravets kjennetegnende del. Ved hjelp av oppfinnelsen kan man oppnå en vesentlig helt plan og helt dekkende fasadebekledning. The present invention relates to a facade cladding of the type specified in the preamble of the main claim and with the special features specified in the characterizing part of the main claim. With the help of the invention, it is possible to achieve a substantially completely flat and completely covering facade cladding.

Fig. 10 viser et detalj av fig. 5 i større målestokk . Fig. 10 shows a detail of fig. 5 on a larger scale.

I fig. 1,2,3 og 4 er det vist et fasadeelement 1 som har en vesentlig plan overflate 2 som er beregnet til å utgjøre ytterflate når fasadeelementet. er montert på et hus. Fra overflaten 2 er to parallelle sidekanter 3,4 nedbøyd. Disse sidekantene 3,4 er beregnet til å utgjøre fasadeelement^ ets 1 vertikale sider. Videre er det utformet en øvre tunge 5 fra overflatens 2 øvre kant 6 og en nedre tunge 7 formet fra overflatens 2 nedre kant 8. Tungene 5,7 strekker seg oppover og innover, slik som det fremgår av fig. 3, og danner således en vinkel med overflaten 2. I det.minste den ene av nevnte sidekanter 3,4 er dessuten bøyd innover, slik at den innoverbøyde delen sammen med overflaten danner en U-formet profil, noe som best fremgår av fig. 5. Den U-formede profilens frie ben 9,10 er forsynt med nøkkelhullåpninger 11,12. Nøkkelhullåpningene 11,12 er beregnet til å samvirke med et festeorgan som omfatter skruer eller lignende,for fastsettelse av et element 1. Fasadeelementet 1 er beregnet for å plasseres på en slett og har begge sidekantene 3,4 bøyd ned og bøyd innover for dannelse av den nevnte U-profil. Det frie benet 9,10 av den U-formede profilen er ved hjelp av nevnte nøkkel-hullåpninger festet i et festeorgan som fortrinnsvis omfatter en i det vesentlige U-formet bjelke 13 som er vertikalt eller horisontalt festet på en husvegg 41. Bjelken 13 er forsynt med skruer 14 eller lignende i de frie endene, hvilke skruer er beregnet til å samvirke med nøkkelhullåpningene 11,12, slik som vist i fig. 5- In fig. 1, 2, 3 and 4, a facade element 1 is shown which has a substantially flat surface 2 which is intended to constitute the outer surface when the facade element reaches it. is mounted on a housing. From the surface 2, two parallel side edges 3,4 are bent down. These side edges 3,4 are intended to form the vertical sides of facade element 1. Furthermore, an upper tongue 5 is formed from the upper edge 6 of the surface 2 and a lower tongue 7 is formed from the lower edge 8 of the surface 2. The tongues 5,7 extend upwards and inwards, as can be seen from fig. 3, and thus forms an angle with the surface 2. At least one of said side edges 3,4 is also bent inwards, so that the inwardly bent part together with the surface forms a U-shaped profile, which is best seen in fig. 5. The free legs 9,10 of the U-shaped profile are provided with keyhole openings 11,12. The keyhole openings 11,12 are intended to cooperate with a fastening device comprising screws or the like, for fixing an element 1. The facade element 1 is intended to be placed on a plain and has both side edges 3,4 bent down and bent inward to form the aforementioned U-profile. The free leg 9, 10 of the U-shaped profile is fixed with the help of said keyhole openings in a fastening device which preferably comprises an essentially U-shaped beam 13 which is vertically or horizontally fixed to a house wall 41. The beam 13 is provided with screws 14 or the like at the free ends, which screws are intended to cooperate with the keyhole openings 11,12, as shown in fig. 5-

De nevnte tunger 5,7 er i sine frie ender bøyd i retning bort fra nevnte overflates 2 bakside, slik at den bøyde delen 15,16 danner en V-form, der den nedre tungens 7 V-formede del 16 på et element la er innpassbar i et under sistnevnte element la forekommende elements lb øvre tunges 5 V-formede del 15, se fig. 8. Derved oppnås således en låsing mellom to vertikalt nærliggende elementer la,lb. Disse tungene medfører at vann ikke kan trenge via skjøten mellom to i vertikal retning nærliggende elementer. The said tongues 5,7 are bent at their free ends in a direction away from the backside of said surface 2, so that the bent part 15,16 forms a V-shape, where the V-shaped part 16 of the lower tongue 7 on an element la can be fitted into a V-shaped part 15 of the upper tongue 5 of the upper tongue of the element 1a occurring below the last-mentioned element 1a, see fig. 8. Thereby, a locking is thus achieved between two vertically adjacent elements la, lb. These tongues mean that water cannot penetrate via the joint between two vertically adjacent elements.

Pasadeelementene 1 monteres hensiktsmessig nedenfra og oppover på en husvegg, hvorved et øvre element la fast-settes ved hjelp av nøkkelhullåpningene 11,12 og skyves nedover mot et nedre element lb, idet ovennevnte låsing opp-trer. Fortrinnsvis går den øvre kanten av overflaten 2 over i det øvre tungen over en kort ansats 17, vinkelrett mot overflaten 2, se fig. 8. Den nedre kanten 8 av et fasadeelement er forsynt med en motsvarende ansats 18. Ansatsen 17,18 medfører at det oppnås en distinkt innbyrdes stilling mellom to på hverandre monterte fasadaelementer la, lb. The pasade elements 1 are suitably mounted from below upwards on a house wall, whereby an upper element 1a is fixed by means of the keyhole openings 11,12 and pushed downwards towards a lower element 1b, the above-mentioned locking occurring. Preferably, the upper edge of the surface 2 passes into the upper tongue over a short projection 17, perpendicular to the surface 2, see fig. 8. The lower edge 8 of a facade element is provided with a corresponding abutment 18. The abutment 17,18 means that a distinct relative position is achieved between two facade elements la, lb mounted on each other.

Fasadaelementer lc,ld, beregnet for å plasseres slik at de utgjør et hjørne på et hus, såkalt hjørneelementer lc,ld, har sin ved hjørnet beliggende sidekant 19,20 innbøyd under overflaten 21, slik at hvert hjørneelement danner en vinkel på 45° mot overflaten 21, se fig. 6. De to sidekantene 19,20, hver og en tilhørende et på de to sidene av husets hjørner i horisontal retning nærbeliggende elementer lc,ld, Facade elements lc,ld, intended to be placed so that they form a corner of a house, so-called corner elements lc,ld, have their side edge 19,20 situated at the corner bent under the surface 21, so that each corner element forms an angle of 45° to the surface 21, see fig. 6. The two side edges 19, 20, each one belonging to an element lc, ld that is close to the corners of the house in the horizontal direction,

er beregnet til å ligge an mot hverandre, hvorved hjørneelement-enes overflater 21 møtes i rett vinkel i hjørnet. Festeanordningen i den lengst fra hjørnet beliggende enden av hjørne-elementet lc,ld utgjøres av ovennevnte festeanordning 11,12,13, 14. Festeanordningen i hjørnet for hjørneelementet lc,ld, utgjøres av sidekantene 3,4. Det ene hjørneelementets ld sidekant 20 som ligger i hjørnet er bøyd for at det i dets ytre ende skal dannes en U-form med den U-formede delens 22 frie ben 23, som er gitt en sagtannform, vendende mot det i hjørnet are intended to rest against each other, whereby the corner element's surfaces 21 meet at right angles in the corner. The fastening device in the farthest from the corner end of the corner element lc,ld is made up of the above-mentioned fastening device 11,12,13, 14. The fastening device in the corner for the corner element lc,ld is made up of the side edges 3,4. The side edge 20 of one corner element 1d which lies in the corner is bent so that a U-shape is formed at its outer end with the free leg 23 of the U-shaped part 22, which is given a sawtooth shape, facing towards it in the corner

nærbeliggende andre hjørneelementet.lc. Det andre hjørne-elementets lc sidekant 19 som ligger i hjørnet er bøyd for at det i dets ytre ende skal dannes en V-form, med den V-formede delens 24 frie kant 25 vendende inn mot hjørneelementets lc overflates 21 bakside. Derved er hjørneelementene lc,ld sammenfestet ved at det andre hjørneelementets lc V-formede del 24 skyves inn i det førstnevnte elementets ld U-formede del 22, hvorved den V-formede delens frie ende er beregnet til å ligge an og låses mot den U-formede delens sagtannede frie ben 23. nearby other corner element.lc. The side edge 19 of the second corner element lc which lies in the corner is bent so that a V-shape is formed at its outer end, with the free edge 25 of the V-shaped part 24 facing towards the back side of the surface 21 of the corner element lc. Thereby, the corner elements lc,ld are joined together by the V-shaped part 24 of the second corner element lc being pushed into the U-shaped part 22 of the first-mentioned element ld, whereby the free end of the V-shaped part is intended to rest against and lock against the U -shaped part's serrated free leg 23.

Fasadeelementer for fasadedeler som er beliggende vinkelrett mot den vesentlige hovedfasadens plan, såsom rundt vinduer og dører, såkalte vindus- og døråpningselementer 26 utgjør festeanordninger for de ovenfor beskrevne f asadeelement er 1 som grenser mot vinduer og dører etc. Et vindus-r og døråpningselement 26 utgjøres av et element som er formet på ønsket måte etter nevnte fasadedel, hvilken i sin mot den vesentlige husfasaden 27 nærliggende enden er bøyd til en U-formet del 28, der det frie benet 29 på den U-formede delen er gitt en sagtannform, se fig. 7- Et for den vesentlige fasaden 27 beregnede fasadeelementets le ene sidekant er beregnet for å skyves inn i nevnte U-formede del 28,. hvilken sidekant derfor i sin ytre del 30 er gitt en V-form, slik at den lås.es mot den U-formede delens 2'8 sagtannede frie ben 29. Vindus- eller døråpningselementet 26 spikres hensiktsmessig fast i vindus- eller dørkarmen. I fig. 7 er det vist som et eksempel et vindusåpningselement 26, der i fig. 7 vinduskarmen er betegnet med 31 og vindusglasset med 32. Facade elements for facade parts that are located perpendicular to the plane of the essential main facade, such as around windows and doors, so-called window and door opening elements 26 constitute fastening devices for the above-described f facade element is 1 that borders windows and doors etc. A window-r and door opening element 26 consists of an element that is shaped in the desired way according to said facade part, which at its end close to the main house facade 27 is bent into a U-shaped part 28, where the free leg 29 of the U-shaped part is given a sawtooth shape, see fig. 7- One side edge of the facade element calculated for the essential facade 27 is calculated to be pushed into said U-shaped part 28. which side edge is therefore given a V-shape in its outer part 30, so that it is locked against the saw-toothed free legs 29 of the U-shaped part 2'8. The window or door opening element 26 is suitably nailed to the window or door frame. In fig. 7 shows as an example a window opening element 26, where in fig. 7 the window frame is denoted by 31 and the window glass by 32.

Over- og underkant på et vindus- eller døråpnings-element som grenser mot et fasadeelement er utformet med tunger på motsvarende måte som beskrevet ovenfor med hensyn til fasadeelementene 1. The upper and lower edge of a window or door opening element that borders a facade element is designed with tongues in a corresponding manner as described above with respect to the facade elements 1.

Ved anbringelse av de ovenfor beskrevne fasadeelementene, også omfattende hjdrneelementer samt vindus- og døråpningselementer, overlappes to i vertikal åpning nærbeliggende elementer av de nevnte tungene. Videre er i horison-talretning nærliggende elementer plassert med sidekantene tett inntil hverandre. Dette medfører således at en i hovedsaklig plan, heldekkende fasadebekledning oppnås. I en utførelse er fasadeelementene utført slik at de ligner-husets fasade. When placing the above-described facade elements, also comprising corner elements as well as window and door opening elements, two vertically adjacent elements of the aforementioned tongues are overlapped. Furthermore, in the horizontal direction, adjacent elements are placed with the side edges close to each other. This thus results in an essentially flat, full-covering facade cladding being achieved. In one embodiment, the facade elements are designed so that they resemble the house's facade.

I fig. 10 vises den ytre delen av'U-bjeiken 13 In fig. 10 shows the outer part of the U-bend 13

i større målestokk. Fra fig. 10 fremgår det at skruen 14 on a larger scale. From fig. 10 it appears that the screw 14

eller lignende fortrinnsvis utgjøres av en stift som er for-skyvbart i et hull 34 i U-bjeikens ytre flens 35- Skruen 14 or the like is preferably made up of a pin that can be moved into a hole 34 in the U-shaped outer flange 35 - The screw 14

er således ettergivende relativt U^bjelken et stykke i lengde-retningen. Et fjærende legeme 33, som kan utgjøres av et fjærende materiale eller en fjær, er anordnet rundt skruen 14 for å oppnå at den er ettergivende under et motsvarende fjærtrykk. is thus compliant relative to the U^beam for a distance in the longitudinal direction. A resilient body 33, which can be constituted by a resilient material or a spring, is arranged around the screw 14 to achieve that it is flexible under a corresponding spring pressure.

Ved hjelp av den beskrevne utforming av fasadeelementet 1 og ved de ettergivende skruene 14, er det mulig å ta bort et ønsket fasadeelement 1 fra en fasadebekledning og erstatte det fjernede elementet med et nytt. I fig. 9a-d illustreres hvorledes fjerningen av et fasadeelement lf i prinsipp går for seg. Fig. 9a viser utgangsstillingen når fasadeelementet lf sitter på plass. Ved fjerning innstikkes en sparkel eller lignende i skjøten mellom det ønskede fasadeelementet lf som skal fjernes, og det ovenforliggende elementet lg. Ved hjelp av sparkelen fjernes det øvre elementet lg noe fra husveggen, slik som vist med pilen 36, hvorved tungenes 5,7 V-formede deler 15,16 løsner fra hverandre. Deretter løftes det ønskede elementet opp, slik som vist med pilen 37, inn under det øvre elementet lg inntil det ønskede elementet er borttagbart fra de skruer 14 i hvilke det er festet. Deretter bøyes den nedre delen av det ønskede elementet ut, slik som vist med pilen 38, og elemente,t trekkes ut slik som vist med pilen 39. Isetting av et element skjer på tilsvarende måte i omvendt orden. By means of the described design of the facade element 1 and by the yielding screws 14, it is possible to remove a desired facade element 1 from a facade cladding and replace the removed element with a new one. In fig. 9a-d illustrates how the removal of a facade element lf in principle proceeds. Fig. 9a shows the initial position when the facade element lf is in place. When removing, insert a trowel or similar into the joint between the desired facade element lf to be removed, and the element lg above. With the help of the trowel, the upper element lg is removed somewhat from the house wall, as shown by the arrow 36, whereby the V-shaped parts 15, 16 of the tongues 5.7 detach from each other. The desired element is then lifted up, as shown by arrow 37, under the upper element 1g until the desired element can be removed from the screws 14 in which it is fixed. Then the lower part of the desired element is bent out, as shown by arrow 38, and element,t is pulled out as shown by arrow 39. Inserting an element takes place in a similar way in the reverse order.

Det rommet 40 som dannes mellom husets vegg 41, fasadebekledningens 1 innside og mellom to nærliggende U-bjelker 13 kan fortrinnsvis fylles med isoleringsmateriale 42, .f.eks. mineralull eller lignende. Blant annet denne mulighet som oppnås ved hjelp av foreliggende oppfinnelse er meget hensiktsmessig å benytte ved en ytterligere isolering av isolerte hus samt ved isolering av uisolerte hus. Nevnte U-bjelkers 13 lengde vinkelrett mot husveggen tilpasset for en ønsket tykkelse på isolasjonen. The space 40 that is formed between the house's wall 41, the inside of the facade cladding 1 and between two nearby U-beams 13 can preferably be filled with insulating material 42, e.g. mineral wool or similar. Among other things, this possibility which is achieved with the help of the present invention is very appropriate to use for further insulation of insulated houses as well as for insulation of non-insulated houses. Said U-beams 13 length perpendicular to the house wall adapted for a desired thickness of the insulation.

Foreliggende oppfinnelse angår således en fasadebekledning som omfatter fasadeelementer samt festeanordninger, hvilke elementer kan settes opp enkelt og danner en vesentlig plan, heldekkende fasade. En stor fordel er at fasadeelementene plasseres et stykke fra husveggen hvorved ytterligere isolering av isolerte hus eller isolering av uisolerte hus på en enkel måte muliggjøres. Videre er det en meget stor fordel at hvilket som helst fasadeelement kan bygges ut, uten at noen andre fasadeelementer behøver fjernes, til tross for det faktum at fasaden er helt dekkende i ett plan. The present invention thus relates to a facade covering which includes facade elements and fastening devices, which elements can be set up easily and form a substantially flat, fully covering facade. A major advantage is that the facade elements are placed some distance from the house wall, whereby further insulation of insulated houses or insulation of non-insulated houses is made possible in a simple way. Furthermore, it is a very big advantage that any facade element can be built out, without any other facade elements needing to be removed, despite the fact that the facade is completely covering in one plane.

Oppfinnelsen er ikke begrenset til de ovenfor angitte utførelsesformer, men kan varieres innen rammen for de etterfølgende patentkrav. The invention is not limited to the above stated embodiments, but can be varied within the scope of the subsequent patent claims.
