Denne opfindelse angår et pladeelement til opbygning af ikke-plane lofter, især inderlofter i butikker, restauranter, kontorer eller lignende bygninger, hvor man vil have et bølget loft.This invention relates to a slab element for the construction of non-planar ceilings, especially interior ceilings in shops, restaurants, offices or similar buildings where a wavy ceiling is desired.

5 I butikker, restauranter, kontorer eller lignende bygninger forekommer ofte akustiske problemer af forskellig art, som man ønsker at eliminere så godt som muligt. Man vil jo imidlertid samtidigt gøre det på en æstetisk tiltalende måde, og man har så visse æstetiske synspunkter vedrørende 10 disse pladeelementer, som ofte anvendes.5 Acoustic problems of various kinds are often found in shops, restaurants, offices or similar buildings, which you want to eliminate as much as possible. You will, however, at the same time do so in an aesthetically pleasing way, and you then have certain aesthetic views regarding these plate elements, which are often used.

Pladeelementerne kan være uperforerede og har dermed kun en lydreflekterende overflade. For at tilvejebringe en lydabsorberende overflade kan pladeelementerne være perforerede og eventuelt også belagt med en lydfilt. Lydfilten kan 15 anbringes på loftselementets bag- eller forside eller på begge sider. En sådan lydfilt kan være en tynd mineral-fiberfilt.The plate elements may be unperforated and thus have only a sound reflecting surface. In order to provide a sound-absorbing surface, the plate elements may be perforated and optionally also coated with a sound blanket. The sound blanket can be applied to the back or front side of the ceiling element or to both sides. Such a sound blanket may be a thin mineral-fiber blanket.

For at tilvejebringe et loft med bølget udformning kræves det, at pladeelementerne bøjes på passende måde. Den bøj-20 ning af pladeelementerne, som anvendes på ét sted, passer måske ikke på et andet, hvorfor man ønsker at kunne udforme lofterne forskelligt.In order to provide a ceiling with a wavy design, the plate elements are required to be flexed appropriately. The bending of the plate elements used in one place may not fit another, which is why it is desirable to be able to design the ceilings differently.

Hvis man fremstiller færdigtbøjede pladeelementer, vil disse kræve stort volumen af lagerlokaler og også have 25 store transportvolumen. Dette er et stort problem, idet især transporterne fordyres, og risikoen for transportskader forøges. Det er derfor ønskeligt at tilvejebringe et pladeelement, som kan lagerføres og leveres plant og bøjes til den form, det skal have i forbindelse med, at det 3 0 monteres.Manufacturing pre-bent plate elements will require a large volume of storage space and also have 25 large transport volumes. This is a major problem, as transport in particular is expensive and the risk of transport damage increases. It is therefore desirable to provide a plate element which can be stocked and delivered flat and bent to the shape it should have in connection with its mounting.

Den foreliggende opfindelse tilvejebringer et sådant element, hvor pladedelen leveres helt plan.The present invention provides such an element where the plate part is delivered completely flat.

Ifølge opfindelsen er pladeelementet sammensat af et i en dimension krummet pladestykke, hvis rette kanter er op-bukket til flanger, og hvis bøjede kanter er ombøjet således, at der dannes en fold langs størstedelen af de krumme 5 kanter, og hvor flanger på krumme, afstivende profiler er indskudt i folden således, at de afstivende profiler kommer til at bestemme pladens krumning.According to the invention, the plate element is composed of a one-dimensional curved plate, the right edges of which are curved into flanges and whose curved edges are bent so as to form a fold along most of the curved 5 edges, and where flanges on curved, bracing profiles are inserted into the fold so that the bracing profiles determine the curvature of the plate.

Elementet er med fordel indrettet således, at de afstivende profiler låses, så at de ikke utilsigtet kan glide ud af 10 folden. Denne låsning kan eksempelvis ske ved hjælp af lim.The element is advantageously arranged such that the stiffening profiles are locked so that they cannot inadvertently slip out of the fold. This locking can be done, for example, by means of glue.

En anden måde at tilvejebringe låsningen på sker ved hjælp af riller eller lignende.Another way of providing the locking is by means of grooves or the like.

En yderligere måde, hvorpå låsningen kan udføres, går ud på, at de afstivende profilers krop rager ind i en udspa-15 ring eller mellem flige i opbukningen langs de rette kanter. Dette kan ske ved, at der findes udsparinger i en indefter opbukket kant på den opbukkede del af de rette kanter.A further way in which the locking can be carried out is that the body of the stiffening profiles protrudes into a recess or between tabs in the bend along the straight edges. This can be done by the recesses being found in a curved edge of the curved part of the straight edges.

Endvidere kan låsningen ske derved, at tunger er udformet 20 i de opbukkede dele af de rette kanter. Tungerne bukkes indefter, så at de afstivende profiler hindres i at glide ud af folden.Furthermore, the locking can be effected by the fact that tongues are formed 20 in the curved parts of the straight edges. The tongues are bent inward so that the stiffening profiles are prevented from sliding out of the fold.

Tungerne anbringes fortrinsvis således, at de i væsentlig grad er parallelle med de rette kanter. Endvidere udformes 25 de således, at tungeroden nærmest er pladeelementets centerlinje. Tungerne er indadbøjede, så at de fjedrer udefter, når afstivningsprofilens krop føres forbi, og derefter fjedrer tilbage. Den afstivende profil hindres derved i at blive ført tilbage.The tongues are preferably arranged such that they are substantially parallel to the straight edges. Furthermore, they are formed such that the tongue root is closest to the center line of the plate element. The tongues are bent inwards so that they spring outwards as the body of the stiffening profile is passed and then springs back. The stiffening profile is thereby prevented from being retracted.

* 30 En yderligere måde til opnåelse af profilernes låsning går ud på, at der i de opbukkede dele af de rette kanter er udformet indskæringer eller indhak. Indhakkene udformes således, at de tillader, at en afstivende profil presses DK 170652 B1 3 forbi og ind i folden. Den opbukkede del bliver da fjedrende presset udefter af den afstivende profils krop, og når kroppen er blevet ført forbi, vender den opbukkede del tilbage og hindrer derfor de afstivende profiler at glide 5 tilbage ud af indhakket.* 30 A further way of obtaining the profile locking is that cut-outs or notches are formed in the curved parts of the straight edges. The notches are designed to allow a stiffening profile to be pushed past and into the fold. The bent part is then resiliently pressed outwards by the body of the stiffening profile, and when the body has been passed, the bent part returns and therefore prevents the stiffening profiles from sliding 5 out of the notch.

Opfindelsen vil i det følgende blive nærmere beskrevet ved hjælp af de tilhørende tegninger 1-7, der viser pladeelementet i nogle forskellige udformninger samt forskellige låsninger af profilerne.The invention will now be described in more detail with reference to the accompanying drawings 1-7 showing the plate element in some different designs as well as different locking of the profiles.

10 I fig. la er der vist to mod hinanden anbragte pladestykker 1. Hvert af disse har en ombøjet kant eller flange 2, som danner en fold 3. Naturligvis har hvert pladeelement 1 over for den viste kant også en ombukket kant. I figuren vises endvidere, hvordan en T-profil 4's ene flig er indskudt i 15 folden 3. Den af stivede T-profil 4 er bøjet, hvilket ikke er vist på tegningen, på en sådan måde, at pladestykket 1 vil blive bøjet, når T-profilen tvinges ind i folden 3, hvorved pladestykket får den ønskede krumning. T-profilerne 4 i den her viste udførelsesform kan udskiftes med andre 20 passende profiler.10 In FIG. 1a, two plate pieces 1 are shown facing each other. Each of these has a bent edge or flange 2 which forms a fold 3. Of course, each plate element 1 opposite the edge shown also has a bent edge. The figure also shows how one tab of a T-profile 4 is inserted into the fold 3. The stiffened T-profile 4 is bent, which is not shown in the drawing, in such a way that the plate piece 1 will be bent when The T-profile is forced into the fold 3, thereby giving the sheet piece the desired curvature. The T-profiles 4 in the embodiment shown here can be replaced with other suitable profiles.

I fig. lb er det vist, hvordan man ved hjælp af en limfuge 6 fastlåser T-profilen 4's flig 5 i folden 3.In FIG. 1b, it is shown how to lock tab T-profile 4's tab 5 in the fold 3 by means of a glue joint 6.

Fig. lc viser en anden måde til fastlåsning af profilen's flig 5 i folden 3, nemlig ved tilvejebringelse af et ind-25 greb mellem fligen 5 og flangen 2. Dette indgreb kan, som det fremgår af figuren, være vulster 7 og 8, der er anbragt henholdsvis på fligen 5 og flangen 2.FIG. 1c shows another way of locking the tab 5 of the profile in the fold 3, namely by providing an engagement between the tab 5 and the flange 2. This engagement can, as can be seen in the figure, be beads 7 and 8 arranged respectively on tab 5 and flange 2.

Den i fig. 2 viste udførelsesform for opfindelsen angiver yderligere en måde, hvorpå man kan opnå en låsning af T-30 profilen 4, idet man mod hinanden anbringer to pladestykker 1, som sammenholdes med en T-profil 4. For at den afstivende T-profil ikke skal løsnes utilsigtet, er pladestykkerne 1 ombukket to gange, hvorved hvert pladestykke har fået en DK 170652 B1 4 dobbelt fold 3 og 3'. T-profilen er her anbragt i de to pladestykker 1's fold 3'.The FIG. 2, the embodiment of the invention further provides a way of obtaining a locking of the T-30 profile 4, by affixing two plate pieces 1 which are joined together with a T-profile 4. In order that the stiffening T-profile should not If it is unintentionally loosened, the plate pieces 1 are folded twice, whereby each plate piece has been given a double fold 3 and 3 '. The T-profile is here placed in the fold 3 'of the two sheet pieces 1.

Fig. 3a og 3b viser en måde til låsning af profilen 4, så at den ikke kan fjernes fra pladestykket l's fold 3. Plade-5 stykket l's rette kant 9 er opbukket således, at der dannes en flange 10. Flangen 10 har ved sin øverste kant en indefter ombukket kant 11. Denne kant er forsynet med udsparinger eller flige 12. T-profilen 4 anbringes i udsparingen eller mellem fligene 12 på en sådan måde, at T-profilen 10 blive låst fast.FIG. 3a and 3b show a way of locking the profile 4 so that it cannot be removed from the fold 3. of the plate piece 1. The right edge 9 of the plate-5 piece 1 is bent so as to form a flange 10. The flange 10 has at its upper edge an inner folded edge 11. This edge is provided with recesses or tabs 12. The T-profile 4 is placed in the recess or between the tabs 12 in such a way that the T-profile 10 is locked.

T-profilerne 4's låsning kan ske på flere forskellige måder. I fig. 4a og 4b samt 5a og 5b er det vist, hvordan låsningen foretages ved hjælp af flige eller tunger henholdsvis 13 og 14, der er udformet i flangen 10. Disse 15 tunger 13 og 14 kan være udformet på forskellig måde, som det fremgår af figuren. Tungen 13 er bukket på en sådan måde, at den stort set er parallel med T-profilen 4's flig 4, idet tungen 14 er i hovedsagen parallel med T-profilen 4's krop 15.The locking of the T-profiles 4 can take place in several different ways. In FIG. 4a and 4b as well as 5a and 5b, it is shown how the locking is performed by means of tabs or tongues 13 and 14 respectively formed in the flange 10. These 15 tongues 13 and 14 may be formed in different ways as shown in the figure. . The tongue 13 is bent in such a way that it is substantially parallel to the tab 4 of the T-profile 4, the tongue 14 being substantially parallel to the body 15 of the T-profile 4.

20 Fig. 6a og 6b viser yderligere en måde til at hindre den afstivede profil i utilsigtet at blive ført ud af folden 3. Dette sker ved, at der i den ombukkede del, nemlig flangen 10, er udformet tunger 16. Tungerne 16 er anbragt således, at de i væsentlig grad er parallelle med plade-25 stykket l's rette kant. Endvidere er tungeroden 17 anbragt nærmest pladestykket l's centerlinje. Tungerne 16 er lukket indefter, så at de kommer til at fjedre udefter, når afstivningsprofilen 4's krop 15 føres forbi. Efter at afstivningsprofilen 4 er blevet anbragt i folden 3-, vil 30 tungerne 16 blive ført tilbage og dermed foretage en låsning af profilen 4. ^FIG. 6a and 6b further illustrate a way of preventing the stiffened profile from being inadvertently carried out of the fold 3. This is done in that in the folded part, namely the flange 10, tongues 16. The tongues 16 are arranged so that they are substantially parallel to the straight edge of the plate piece 1. Further, the tongue root 17 is located closest to the center line of the plate piece 1. The tongues 16 are closed inwardly so that they will spring outwards as the body 15 of the stiffening profile 4 is passed. After the stiffening profile 4 has been placed in the fold 3, the tongues 16 will be retracted, thus locking the profile 4. ^

Afstivningsprofilens låsning kan også ske på den måde, der er vist i fig. 7a og 7b. Der er her anbragt indhak eller DK 170652 B1 5 indskæringer 18 i flangen 10. Disse indhak 18 er anbragt således, at de tillader, at afstivningsprofilen presses forbi indhakket 18 og ind i folden 3. Dette sker på en sådan måde, at den opbukkede del, nemlig flangen 10, tvin-5 ges udefter af profilen 4's krop 15. Når kroppen 15 er blevet ført forbi indhakket 11, føres flangen 11 tilbage til sin stilling, og den afstivede profil 4 låses.The stiffening profile locking can also be done in the manner shown in FIG. 7a and 7b. There are notches or DK 170652 B1 5 notches 18 provided in the flange 10. These notches 18 are arranged so that they allow the stiffening profile to be pushed past the notch 18 and into the fold 3. This is done in such a way that the bent part namely, the flange 10, the twist 5 is externally of the body 15. of the profile 4 When the body 15 has been passed by the notch 11, the flange 11 is returned to its position and the stiffened profile 4 is locked.
