Definitions

  • the present invention relates to a method for the manufacture of curved ceiling panels comprising a carrier layer in the shape of a sheet of mineral wool containing a binder and having a painted surface and/or a surface coated with woven or unwoven textile or a foil, which surface is suited for being used as ceiling surface in a room. Moreover, the invention relates to a ceiling panel manufactured by this method.
  • the object of the present invention is to provide a method, by means of which it is possible at fairly low costs to produce curved ceiling panels having the same surface structure as corresponding plane panels and with the use of a simple form corresponding to one of the surfaces of the ceiling panel.
  • the rigidity of the panel is reduced to such an extent that when put into the female mould, it will follow its profile. It is therefore possible to take out some panels manufactured in the same series as the remaining panels to be delivered at the same time, split them and rebuild them in the desired curved shape, the layers of adhesive giving the panels their original self-carrying properties and moreover having the a reinforcing effect, thus adding to their rigidity.
  • the invention relates to a ceiling panel of the type manufactured by the method according to the invention.
  • the ceiling panel is characterized by the subject matter of the characterizing clause of claim 6.
  • the layers of adhesive are absorbed in the adjacent layers of mineral wool, the rebuilt panel gets a rigidity, which is at least equal to the rigidity of the panel used as a starting material, even if only one layer of adhesive placed near the neutral plane of the panel is used.
  • the adhesive can only be absorbed in the immediately adjacent layers, there is no risk of a complete*drenching and.subsequent discolouring of the surface coating.
  • fig. 1 is a side-face of a ceiling panel
  • fig. 2 is a section through a part of a ceiling panel according to the invention and through a part of a suspension beam
  • fig. 3 is a section corresponding to fig. 2 through a ceiling panel split into three layers
  • fig. 4 is an enlarged section through the ceiling panel according to fig. 2.
  • ceiling panels which in certain cases be of different levels. There is, therefore, a need for ceiling panels, which in an even curvature may bridge the two levels.
  • a ceiling panel may have a profile seen from the side-face corresponding to the ceiling panel shown in fig. 1.
  • the ceiling panel is manufactured by providing a carrier layer of mineral wool at the surface to form the ceiling of the room with a surface coating, which can be a paint and/or a woven or unwoven textile or possible a perforated foil.
  • the carrier layer of mineral wool has such a thickness and such a content of binder, which binds the fibres at their intersecting points, that the carrier layer without any excessive bending is self-supporting when placed between the flanges 2 of the two suspension beams (figs. 2 and 3).
  • the layer which is at one side provided with the surface layer, is placed against the mould. Then an adhesive is applied to the next layer of the side to face the first layer, said adhesive being sufficiently fluent to penetrate into the part of the mineral wool closest to the incision edge but being on the other hand so viscious or thixotropic that it is not fully absorbed by the mineral wool, which could make it penetrate the whole layer and discolour the surface to form the ceiling after the mounting of the ' panel.
  • the adhesive is allowed to cure, after which the panel is then ready and has been given the desired profile.
  • the ceiling panel 1 shown in fig. 2 has been split into two ⁇ , layers of approximately the same thickness.
  • Fig. 3 shows a sheet 1, which apart from having been spilt by two incisions, corresponds to the sheet according to fig. 2.
  • a fleece for instance of glass fibres.
  • This fleece may be used for appplication of the adhesive, the adhesive being according to its consistency either poured out or applied as a filler onto the fleece or the fleece may be dipped into the adhesive before being replaced during the rebuilding of the ceiling panel.
  • Fig. 4 is a section through a ceiling panel consisting of two layers, in which it is seen that an absorption of the adhesive in the parts of the split mineral wool adjacent to the incision is aimed at.
  • a mineral wool having a specific weight of 60-80 kg/m and a content of binder of 2- 3 per cent.
  • the binder is normally a phenolformaldehyde binder.
  • a PU-glue of a type foaming after application may be used, a fair certainty of the glue joint being completely filled being thus attained.
  • Sadofoss 3930 can be mentioned. This glue has a curing time of approx. half an hour at 20°C, which does to a fair extent secure an effective production and an adequately long "open" time for the rebuilding of the panels.
  • the adhesive may be applied as a uniform layer or in the shape of stripes being placed in parallel and with such a distance that they tend to unite when the layers are joined. Two mutually intersecting rows of stripes may be applied to the sheets, in which case the stripes may have a somewhat bigger mutual distance.

Abstract

Procédé de fabrication de panneaux de plafond courbés comprenant une couche de support de la forme d'une feuille de laine minérale contenant un liant et comportant une surface peinte et/ou une surface revêtue de textile tissé ou non tissé ou bien d'une plaque, ladite surface étant adaptée pour être utilisée comme surface de plafond dans une pièce. Afin de pouvoir fabriquer, à un coût comparativement faible, des panneaux de plafond durcis présentant la même structure de surface que des panneaux plans correspondants et à l'aide d'un moule simple correspondant à une des surfaces du panneau de plafond, le procédé se caractérise en ce que ledit panneau de plafond est subdivisé en un certain nombre de couches au moyen d'au moins une incision s'étendant en parallèle à la surface revêtue et en ce que ledit panneau de plafond est reconstruit sur un moule femelle ayant la courbure voulue, un adhésif durcissable étant placé entre les couches.
