Definitions

  • the invention relates to a roller shutter rod for use in silenced roller shutters consisting of a hollow body with a hook-shaped and a G-shaped connecting end roll-formed aluminum strip.
  • a roller shutter bar is known from BE-A-666 605.
  • the noise occurring on roller shutters can be caused by "internal” and “external” sound sources.
  • noises are generated in the hinge area and in the abutting longitudinal surfaces of the roller shutter slats.
  • a sudden structure-borne noise can be distinguished from a sliding or grinding noise.
  • External sound sources such as wind and rain can also act on the closed roller shutters, causing the well-known drum sound or the sledging or rattling of the roller shutter slats.
  • Roller shutter slats are narrow surface elements that have a very different cross-section, which ranges from an oblong rectangular to a wing-like cross-section with convex and concave-curved surfaces and a large length / width ratio, which promotes sound propagation.
  • the couplings with a different number of hollow profiles that occur when rolling out and rolling in the roller shutter result in a large-area, resonant structure with varying natural frequencies.
  • the closed roller shutter represents a complex vibration system, the damping properties of which were previously not sufficiently manageable.
  • roller shutter rod which instead of hook-shaped or G-shaped connecting ends has folded areas which are arranged on each narrow side of the hollow body profile and project outwards in the longitudinal cross-sectional direction.
  • the individual roller shutter slats are connected to one another at the fold areas by additional connecting means, such as, for example, multi-link chains.
  • the known roller shutter slat consists of an aluminum composite material, which is constructed in a sandwich-like manner from three layers, namely an aluminum carrier material layer, a plastic layer designed as a visco-elastic adhesive layer and a layer made of thin aluminum strip material.
  • the present invention relates to roller shutter slats, which without further connecting means, i.e. without chains, are positively connected to each other solely by the G-shaped or hook-shaped connection ends. It has been shown that the measures known from the prior art for noise reduction, namely the provision of a three-layer composite layer in the interior of the hollow body profile for the noise reduction of such roller shutter bars with G-shaped or hook-shaped connecting ends are not sufficient.
  • This object is achieved in that a plastic layer is extruded or laminated onto the aluminum strip on one side, the coated side of the aluminum strip being directed inwards in the hollow body such that a double-layer plastic layer is formed at the connection ends for mutual sound insulation of the double-layer aluminum strip surfaces there.
  • the invention makes use of a different, more effective type of sound insulation.
  • the beating together was the cause of the sound generation in roller shutter slats with G-shaped or hook-shaped connecting ends the profile areas recognized at the ends, which is associated with an introduction of the sound generated in the connection end area into the interior of the hollow body.
  • the insulation of the aluminum sheets lying one on top of the other prevents transmission of the sound into the hollow bodies of the individual roller shutter slats.
  • the aluminum strip 1 is roll-formed into a hollow body profile with a hook-shaped connection end 3 and a G-shaped connection end 4.
  • the aluminum strip 1 is coated on the inside with a plastic, preferably with a copolymer 2. This can be done by extrusion coating, by applying a liquid or by
  • Figure 2 is a partial cross section acc. AA of Fig. 1 shown enlarged.
  • the aluminum strips 1e, f are pressed together by roll forming. There is a double layer of the copolymer layer 2 between them. If this is to be applied to the aluminum strip by lamination, a commercially available adhesive can be used as an adhesion promoter.
  • a polyethylene copolymer has proven itself for coating the aluminum strips. It is advantageous if the copolymer is provided with sound-absorbing pigments, which are either introduced in the liquid phase during extrusion onto the aluminum strip or are already present in the finished lamination medium.
  • roller shutter or roller shutter slat according to the invention is in no way limited to the embodiments described above. So the hollow body profile can also be equipped with other fillers such as polystyrene balls and the plastic layer consist of a polypropylene. All suitable resins, acrylates and hot melt adhesives such as e.g. Use polyamides.
