Definitions

  • the present invention relates to a soundproofed roller shutter rod made of aluminum or an aluminum alloy in the form of a hollow profile with two walls and an upper and a lower hinge area and a method for producing the soundproofed roller shutter rod.
  • roller shutters are opened or closed or external influences such as Wind or rain on a closed roller shutter inevitably creates more or less strong noise. This applies in particular to roller shutters with roller shutter slats in the form of hollow profiles made of metal.
  • the object of the present invention is therefore to reduce the noise development in roller shutter slats in the form of hollow profiles made of aluminum or aluminum alloys. At the same time, a process is to be developed for the simple and economical manufacture of such soundproofed roller shutter slats.
  • a roller shutter rod made of metal is usually designed as a hollow profile.
  • the cavity is delimited by two elongated walls and the upper and lower hinge area.
  • the walls of the roller shutter slats vibrate. This leads to noise, the cavity of the roller shutter rod having a noise-enhancing effect.
  • These coatings are advantageously applied in the form of colored or colorless lacquer or plastic films. Effective soundproofing is achieved in particular if the weight difference between the coatings on the walls is at least 30%. This difference in weight can be produced in various ways.
  • Coatings with approximately the same specific weight are applied in different layer thicknesses. If the layer thickness of the coatings is to be approximately the same, coating materials with different specific weights are used.
  • the specific weight of paints e.g. can be adjusted by selecting the color pigments. Light paints generally have a higher specific weight than dark paints, especially when the light paints have the relatively heavy pigment TiO2.
  • the coatings are preferably applied to the visible outer surfaces of the roller shutter rod walls.
  • the sound-absorbing effect can be combined with a favorable optical effect. Soundproofing can be further improved by coating at least one of the inner surfaces of the roller shutter bar with a plastic film.
  • the cavity of the roller shutter slat according to the invention can be filled with a filler to increase the stability and rigidity.
  • Plastic foams or foams are preferably used as fillers.
  • roller shutter bar 1 to 4 each show a cross section through the same roller shutter profile, the differences lie in the arrangement of the coatings.
  • the hollow profile of the roller shutter bar is formed by the two walls 1 and 2, which are molded in the upper hinge area 3 and lower hinge area 4 to correspond to connecting ends for further roller shutter bars.
  • the visible outer surfaces of the walls 1 and 2 are provided with the coatings 5 and 6.
  • the layer weights of the coatings 5 and 6 are different.
  • colored lacquer or plastic films with different colors are preferably used in order to achieve a decorative effect in addition to sound absorption.
  • the sound-absorbing effect can be further enhanced by coating 7 on the inner surfaces of the walls 1 and 2 (FIG. 2). Since the asymmetrical weight distribution required for sound absorption is already generated by the two outer coatings 5 and 6, continuous lacquer or plastic films can be used here, i.e. with the same layer weight on both walls.
  • FIG. 3 shows a roller shutter slat according to the invention in which the coatings 8 and 9 have different layer weights the inner surfaces of the walls 1 and 2 are attached. Since these areas are not visible, colorless layers are used that differ in their specific weight or the applied layer thickness.
  • a desired outer coating 10 can be carried out continuously, preferably as a colored lacquer or plastic film (FIG. 4).
  • the coatings 7 and 10 in FIGS. 2 and 4 can also be carried out in two parts with different layer weights. However, you must then be so arranged or adjusted in the layer weight that the asymmetrical weight distribution on the walls 1 u. 2 is retained or even reinforced.
  • a roller shutter rod made of an AlMn1Mg0.5 alloy in the dimensions: Length: approx.1.6m Height: approx. 40 mm Wall thickness: 0.25 mm (without coatings) was produced according to FIG. 1 with the following coatings: Coating 5: white lacquer spec. Weight: 1.74 g / cm3 Layer thickness: 28 ⁇ m Layer weight: approx. 48 g / m2 Coating 6: brown lacquer spec. Weight: 1.4 g / cm3 Layer thickness: 22 ⁇ m Layer weight: approx. 29 g / m2
  • a band made of aluminum or an aluminum alloy is first coated. Several layers lying side by side are applied simultaneously to at least one side of the belt.
  • Each two layers lying next to each other have a different weight.
  • This sequence of layers is repeated over the entire width of the belt.
  • the coated strip is then cut into longitudinal strips with at least two adjacent layers with different layer weights.
  • a strip obtained in this way is formed into a roller shutter bar with two walls and an upper and a lower hinge area. After the shaping, at least one surface of each wall is provided with a coating, the coatings of the walls having a different layer weight. The transitions between the layers lie within the hinge areas.
  • the coatings are preferably applied as colored or colorless lacquer or plastic films.
  • the application can be wet (as a liquid) or dry (e.g. as a film).
  • industrial adhesives can be used as an adhesion promoter between the aluminum tape and the lacquer or plastic film.
  • Low-cost, continuous processes for coating are the coil painting or coil coating process.
  • the transitions between the coatings in the finished roller shutter slat should be as hidden as possible in the hinge areas. This is particularly the case with external coatings important if the layers have clearly visible differences, e.g. due to the color, the layer thickness or unclean transitions between the layers due to the application process. To ensure this, the position of the cuts must be adapted to the profile shape of the finished roller shutter bar when cutting the strips.
  • the strip is divided immediately after two successive layers in the area of the layer transitions.
  • the band is cut at a corresponding distance next to these transitions.
  • the width of the strips is the same for both variants. It corresponds approximately to the sum of the widths of two layers lying next to each other with different layer weights.
  • the strips are preferably formed into the finished roller shutter bars by roll forming. This can be carried out with the currently customary machines for roll forming roller shutter slats from metal strips without any modifications and without the need for additional units.
  • a tape made of an AlMn1Mg0.5 alloy with a width of approx. 1.60 m and a thickness of 0.25 mm was coated on one side by means of tape coating or coil coating.
  • the coating was carried out in such a way that two layers, designated A and B for simplicity, were applied alternately side by side in the longitudinal direction of the tape.
  • the sequence of the layers across the entire width of the belt was therefore ABABAB ...
  • Layers A and B had different layer weights.
  • the width of each individual layer A or B was 68.5 mm.
  • the tape was then cut into longitudinal strips 137 mm wide. The cuts were offset by 7 mm next to the transition points between layers A and Layer B arranged.
  • the layers on each strip were therefore in the following order: Layer A (7 mm), Layer B (68.5 mm), Layer A (61.5 mm).
  • roller shutter slats according to FIG. 1 were produced from these strips by roll forming.
  • the roller shutter slats produced in this way can be used immediately.
  • the cavities can be filled with fillers such as Foams or plastic foams can be filled.
  • the particular advantage of the proposed method lies in the use of the economical, continuous coil coating method for applying the layers lying next to one another. In one process step, a large number of completely coated strips are produced for the forming into roller shutter bars. Another advantage is the uniformity of the layer thickness of the applied layers. This is crucial for maintaining the layer weights or their difference.
