Definitions
- the invention relates to a cassette for false ceiling, which on a Building or room ceiling in particular by means of a support structure is detachably attachable or attachable and some essentially flat cassette floor with a lower visible side and preferably contrasting edges and flanges for attacking a bracket, the cassette bottom a large number of perforations and on the visible side a sound absorbing layer has that is a plaster layer.
- a cassette is described in DE-A-3 936 665.
- the cassette mentioned at the beginning is included sound-absorbing layer, characterized in that the Plaster layer from an organic bound plaster and that in the plaster particles with a Grain size are provided, which are at least partially one dimension larger than the side or diameter dimensions of the perforations in the bottom of the cassette.
- An organically bound plaster can in a simple way on a metal cassette or sheet metal cassette be applied. Through the perforations at the same time mechanically good adhesion achieved. At the same time it is achieved that at least most of the plaster is on the visible side remains because the grain size of the particles in the plaster is chosen accordingly. Nevertheless there is an acoustic transparency maintained or improved because the plaster is porous and the porosity up to the perforations of the actual one Cassette and extends through this.
- the plaster has a spray plaster structure has and if as a binder an aqueous, copolymer Plastic dispersion is provided.
- a spray plaster structure results a somewhat rough surface, which accommodates the sound insulation.
- a high porosity can be achieved.
- Grains preferably marble grains
- the perforations in the bottom of the cassette can be one Have diameters from 1 millimeter to 4 millimeters.
- Perforation size can therefore be corresponding grits within the Plaster should be provided that the perforations are not complete cover, but in turn not or only partially in the Penetrate perforations.
- the layer of plaster can be plastic-bonded sand with embedded Can be marble grain and in particular plastic-bonded sand penetrate all or part of the perforations. This will make the already mentioned mechanical connection of the plaster layer with the perforated cassette bottom improved.
- a further embodiment of the invention can consist in that color pigments are added to the plaster.
- the Soundproofing and absorption plaster an additional Preserve function because the color of a corresponding coffered ceiling can be influenced in any way can.
- a cassette in which by applying an organically bound plaster with spray structure and a corresponding marble grain acoustic transparency and absorbency are improved, without the need for a porous lacquer layer.
- the binder can be an aqueous, polymeric plastic dispersion serve, i.e. a special plaster can be used, as it is known in the construction industry, so that no one additional and complex measures are required to achieve a corresponding To produce plaster.
- a layer that is flame retardant and a relative has a low specific weight of only approx. 1.9 g / cm3.
- There individual plaster layer particles the perforations in the cassette floor can penetrate, the liability against mechanical stress improved.
- a cassette designated as a whole with 1 is used with others such cassettes 1 to form a false ceiling, which on a Building or room ceiling by means of a whole with 2 Retaining structure can be detachably suspended or attached.
- the cassette 1 has a substantially flat Cassette floor 3 with a lower visible side 4 and this opposite upstanding edges 5 or flanges on which one Bracket 6 of the support structure 2 can attack, as in Figure 2 is shown.
- the cassette bottom 3 has a variety of Perforations 7 and according to all figures, the visible side has this Cassette floor 3 on a sound-absorbing layer 8.
- the sound-absorbing layer 8th is a layer of plaster that expediently from an organic bound plaster, which has a correspondingly good adhesion the sheet of the cassette bottom 3.
- This plaster 9 provided with a grain size that is at least partially in their Dimension larger than the side or diameter dimensions of the There are perforations 7 in the cassette base 3.
- the particles 9 or grain sizes mentioned come to lie in front of the perforations 7, but nevertheless due to the let the sound pass through the entire porosity of the plaster, so that the cassette 1 has good acoustic "transparency" and has good sound absorption.
- the plaster is a spray plaster structure Has.
- An aqueous copolymer can be used as the binder Plastic dispersion can be provided, leading to good adhesion leads to the metallic cassette 1.
- the particles or grains 9 already mentioned in the plaster layer 8 can be marble granules, the dimensions of which are approximately 1 millimeter, 1.2 millimeters to 4 millimeters while the perforations 7 in the cassette base 3 to a diameter of 1 millimeter Can have 4 millimeters.
- Figure 3 illustrates that the particles 9 have an irregular, jagged outer dimension and structure, so that some dimensions are smaller, others but again larger than that of the perforations 7 and thus these Grains or particles 9 generally not in the perforations 7 can occur, but also not completely cover them.
- plaster color pigments or Color can be added, so that the cassette 1 a can receive appropriate coloring without this special layer of paint or an additional work step required would be.
- the cassette 1 for suspended ceilings on a building or room ceiling can be detachably suspended in particular by means of a holding structure 2 or is attachable and the one essentially flat Cassette floor 3 with a lower visible side 4 and preferably in contrast, raised edges 5 or flanges for the attack a bracket 6 for interacting with the support structure 2 has a sound absorbing layer on its visible side 8 on.
- the cassette base 3 has a large number of perforations 7.
- the sound-absorbing layer 8 is a plaster layer from an organically bound plaster, in which particles 9 with a grain size is included, which is at least partially a Dimension larger than the side or diameter dimension of the Have perforations 7 in the cassette bottom 3.
