Definitions

  • the invention relates to a cassette for false ceiling, which can be attached to a building or room ceiling by means of a support structure or the like and which has a particularly flat cassette floor with a lower visible side and, in contrast, upstanding edges or flanges for attacking a holder.
  • cassettes made of metal for building interior construction are known and are generally used with recurring dimensions, for example they have a square basic shape and visible side. This results in a simple holding or substructure on which these cassettes can be fixed in a detachable and easily replaceable manner.
  • cassettes can tend to vibrate and resonate under sound pressure, in particular because of the most economical material thickness, for example less than 1 mm. Furthermore, for optical reasons, it may be desirable not to make the underside of the ceiling uniform or completely flat, but to loosen it up, which then has previously required complex special cassettes.
  • a profiled or corrugated plate is also attached to the visible surface of the cassette for expanding the light beam.
  • the stability of the metallic plate of the cassette forming the cassette bottom can thereby be increased and a kind of sandwich effect can be achieved.
  • the cassette bottom is no longer level from the visible side, but structured by the profiled or corrugated plate. Since this plate is attached to the visible side of a cassette floor of a given or commercially available cassette, it can advantageously be fastened to the previous support structure, i.e. no changes need to be made to this support structure and even the smooth cassettes of already installed ceilings can be made to be replaced by the cassette according to the invention. Depending on the type of fastening of the profiled or corrugated plate, even cassettes of a ceiling can subsequently be made into a cassette according to the invention.
  • the plate is attached to the cassette by gluing, spot welding and / or screws and the cassette has a two-layer cassette bottom.
  • the original cassette base and the corrugated plate attached to it then form the two layers, which stabilize each other and can intercept and dampen vibrations.
  • the increased stability of a square cassette, for example, also reduces its sagging or deformation.
  • the waves of the plate are rounded in cross-section and in particular are of the same size. This results in uniform stability conditions and the corrugated sheet has a largely uniform strength over its entire extent and, especially with respect to bends transverse to the shafts, high stability.
  • Waves and troughs can also be the same size, also to each other, so that a relaxed yet regular appearance can be achieved and the strength at practically all points of the cassette is largely the same.
  • the profiled plate can be made of steel or an aluminum alloy and in particular can be fastened to a cassette made of the same material or to a cassette made of steel.
  • a steel cassette can be combined with a steel plate or with an aluminum alloy plate. This can also influence sound phenomena favorably and at the same time improve stability.
  • the profiled plate is perforated or perforated, in particular has a large number of perforations, preferably on the profile sections or waves projecting downwards in the use position. These waves projecting downwards and the former cassette floor above them then form a cavity that can absorb and absorb the incoming sound.
  • a cassette for a false ceiling which can be attached to the place of a previous cassette of this type, but has a corrugated visible side, in which the cassette bottom is stabilized by a corrugated plate, so that there is also the risk of Vibrations and resonance vibrations as well as deformations caused by sagging are avoided or at least reduced are.
  • the beam expansion in particular daylight, can also influence the lighting data.
  • a cassette designated as a whole by 1 serves to form a false ceiling on a building or room ceiling in repeated repetition.
  • it has a cassette base 2, the underside of which forms the visible side of this cassette in the position of use. Due to the flat design, such a cassette floor can reflect sound in an unpleasant manner and, due to the low material thickness, can also vibrate and resonate due to sound pressure or sudden sound waves.
  • this cassette base there are flanges 3 on which, according to FIG. 1, perforations 4 are provided for connection to a holding structure 5 shown in FIG. You can two such edges 3 lie against each other and are jointly attached to a profile 6 of such a holding structure 5, so that the cassette floors 2 are in one position in the use position.
  • the smooth underside of the cassette base 2 has a corrugated plate 7 which can be attached to the cassette 1 by gluing, spot welding or screws.
  • the cassette base 2 has two layers and is therefore more stable against deformation due to the weight of the cassette on the one hand and also against oscillations and vibrations on the other.
  • optical effects can be achieved, for example, by arranging all the shafts 8 and troughs 9 parallel to one another or else from cassette to cassette at right angles to one another, in particular if the cassettes 1 are square.
  • the waves 8 and the troughs 9 of the corrugated plate 7 are rounded in the exemplary embodiment and correspond approximately to a sine curve and are also each of the same size.
  • other arrangements of the shafts and other cross sections of the profiling of the plate 7 are also conceivable.
  • the profiled or corrugated plate 7 can additionally be perforated or perforated and have a plurality of perforations 11 on the shafts 8 projecting downwards in the use position, so that the sound in the space 10 between a shaft and the original cassette base 2 can be absorbed.
  • the corrugated structure also has a favorable influence on sound reflection in the sense that a sound damping effect can be achieved, depending on the choice of the curvature on the individual shafts and their characteristics or dimensions.
  • the cassette 1 for suspended ceiling which can be detachably suspended or attached to a building or room ceiling by means of a holding structure 5 and which has a particularly flat cassette floor 2 with a lower visible side and, in contrast, upstanding edges or flanges 3 for attacking a holder 6, instructs their visible surface - also for expanding the light beam - has a profiled or corrugated plate 7, which also reduces or avoids the risk of vibrations or resonance vibrations, i.e. irregular sound reflection and thus sound attenuation and furthermore a widening of a reflected compared to an incident light beam.
