Definitions

  • the present invention relates to a ceiling panel capable of bending into the shape of a curve and a method of manufacturing such.
  • glasswool panels installed with the help of support moulding are generally used in ceilings.
  • a flat ceiling is not difficult to make, but construction of a curved ceiling is complicated.
  • curved ceilings have been made of pressed-to-shape pieces, the manufacture of which calls for expensive moulds and the transport of which is difficult. Furthermore, fitting the pieces together in the assembly stage sets great demands on the dimensional accuracy of the pieces.
  • An object of the invention is to provide a panel capable of bending into the shape of a curve, by means of which panel the drawbacks described above can be avoided. Another object is to provide a method of manufacturing such panel.
  • the ceiling panel according to the invention is mainly characterized in that it comprises a mineral wool layer containing fibers bonded together, the direction of extension of the fibers being mainly perpendicular to an underlayer/layer fabric attached to one side of the fiber layer.
  • the method according to the invention for manufacturing ceiling panels is mainly characterized in that a mineral wool mat which is coated on both sides thereof with an underiayer fabric and the fibers of which mat have been caused to rise from a horizontal position to a mainly vertical position at the manfufacturing stage of the mat, is cut along its centerline into two layers and that the layers cut apart from each other are cut into panels of a suitable size.
  • the fiber structure is, for technical reasons, primarily parallel to the surface of the panel, which is why the compression strength of the panel is low in the direction perpendicular to the plane of the panel.
  • the panel according to the invention is manufactured from a mineral wool sheet, the main portions of the fibers of which axe, in the ⁇ mani'fcic-turing stage -with *the panel regarded lying in a horizontal position, forced to rise fxom the hitherto normal, horizontal disposition to a substantially vertical disposition in such a manner that the fibers proceed steeply wavelike in the base sheet when viewing the profile of the base sheet. This is brought about by decreasing the speed of the mineral wool mat between the top and the bottom wires used in the manufacturing prior to conveying the mat into the heat treatment oven for hardening of the bonding agents.
  • This "shrink" panel is already coated on both sides thereof in the processing stage with an underiayer fabric (25 - 50 g/m 2 glass tissue) which provides an even base for final coating of the panel.
  • the underiayer fabric is attached to the base sheet by means of the resin contained in the base sheet.
  • the base sheet is made twice as thick as that required for the final product plus working allowance.
  • This base sheet which is coated on both sides thereof with an underiayer fabric and which naturally is stiff in this stage, is sawn along its centerline into two layers. In that way, one surface of both layers is coated with an underiayer fabric, which provides an even base for the final coating.
  • the fibers are mainly in the vertical position.
  • the final product After sawing, the final product has, due to the presence of vertical fibers, sufficient compression strength and solidity so that the panel can be installed to rest freely on mouldings.
  • the sawing of the base sheet in two since the sawing of the base sheet in two is effected mainly perpendicularly to the fibers, the tensile and compression forces are not subjected to the fibers in the direction of the fibers when the sheet is being bent, but perpendicularly to the fibers. Thus, the sheet bends well because of lack of horizontal bonds in the back thereof.
  • the base sheet layers sawn apart are laminated with a final coating fabric on that side -which is coated with an underiayer fabric.
  • Fig. 1 is a cross-sectional illustration of a stage of manufacture of a ceiling panel in accordance with the method of the invention
  • Fig. 2 is a cross section of a panel according to the invention
  • Fig. 3 is a schematic, fragmentary perspective illustration of a ceiling structure assembled from ceiling panels according to the invention.
  • a glasswool mat 2 illustrated in Fig. 1 is manufactured by a method known per se from fibers and bonding agents suspended in a gas flow by collecting the fibers onto a conveying belt, below which a suction box is disposed.
  • the main length of the fibers are forced to rise from their normal, horizontal position to a vertical position so that the fibers will mainly extend in the vertical position in the middle of the mat.
  • the fiber mat is coated on both sides thereof with an underiayer fabric 3, which is attached to the mat by means of the resin contained in the mat.
  • the coated mat 1 is sawn or otherwise separated along its centerline 4 into two layers 2' and the sides of the layers sawn apart from each other which are coated with the underiayer fabric 3 are laminated with a coating fabric 6, whereafter they will be cut into ceiling panels 5 (Fig. 2) of a suitable size.
  • the underiayer fabric 3 is preferably formed of nonwoven fabric made from glasswool, the basis weight of such fabric bei ⁇ g 25-50 g/m 2 .
  • the coating fabric 6 is preferably formed of nonwoven fabric made from glasswool, the basis weight of such fabric being 50-200 g/m 2 .
  • the thickness of the mineral wool layer is preferably 30- 70 mm and the density 30-40 kg/m 3 .
  • Fig. 3 illustrates a ceiling assembly 10 including ceiling panels 5 according to the invention, in which ceiling the panels 5 are bent to form curves to match the curved support moulding 11 and fixed to it, the ceiling itself is suspended by a method known per se with suspension threads 12 extending from the frame construction of the building and the coating fabric 6 forms a smooth suspended ceiling surface which is easy to maintain clean.
  • Example 1 illustrates a ceiling assembly 10 including ceiling panels 5 according to the invention, in which ceiling the panels 5 are bent to form curves to match the curved support moulding 11 and fixed to it, the ceiling itself is suspended by a method known per se with suspension threads 12 extending from the frame construction of the building and the coating fabric 6 forms a smooth suspended ceiling surface which is easy to maintain clean.
  • a mineral wool mat the density of which was about 30 kg/m 3 and thickness 65 mm and which was on both sides thereof coated with glass fabric of 25 g/m 2 , was sawn into two 30 mm thick layers. The surfaces coated with glass fabric of the layers sawn apart from each other were then laminated with another glass fabric, the basis weight of which was 60 g/m 2 . Thereafter, the layers were cut into ceiling panels of 600 mm x 1200 mm. The end product was a flexible panel, the stiffness of which was adequate for installing the panel to rest at its edges on T-moulding.
  • the ceiling panel of the invention provides ceilings which are easy to install. Transport of the panels causes no problems because the panels are flat and not bent intc the shape Of an axe or curve until the installation stage.
  • plastic laminates can be used as the coating fabric of the panel. It will be understood that the panel can be used to other purposes as well.

Abstract

Panneau (5) pour plafond, qui se plie en forme d'arc pour constituer un plafond incurvé (10), et procédé pour fabriquer ce panneau. Le panneau pour plafond comprend une couche de laine minérale (2') à nappe de fibres, la direction des fibres étant essentiellemnt perpendiculaire au tissu de la sous-couche (3), qui est en laine de verre et qui est fixée à l'une des faces de la couche de fibres. Une couche de tissu de revêtement (6) en laine de verre est disposée sur la surface du tissu de sous-couche. Le panneau est fait d'une natte de laine minérale (1) dont les deux faces sont dotées d'un revêtement et dans laquelle, si l'on regarde le panneau en position horizontale, on a fait se dresser les fibres de leur position horizontale normale en une position verticale au cours de la fabrication de la natte.
