Definitions

  • the invention relates to a sound-insulating component for wall structures of the sandwich type, which is used to build sound-insulating partitions.
  • the component consists of two outer cover plates with a core plate which consists of two layers of sound-insulating material, preferably of porous material, for example mineral wool. These layers are attached to a cover plate.
  • the cover plates are connected to one another at least on two opposite edges in such a way that a cavity or air space is formed between the two core layers.
  • Components for wall structures of this type of sandwich or in a layered version are mainly used for the construction of partitions, in particular for removable and removable partitions in offices, also for partitions in railroad cars and finally for partitions in ships, for example for bulkheads or partitions between ship cabins.
  • the components for these partitions or bulkheads should ten should be as thin as possible to save space, but on the other hand they should also be as stable as possible and ensure great sound insulation.
  • the components mostly used consist of two outer cover plates, the space between these cover plates being filled with core plates or layers, preferably made of porous material.
  • the porous material can be mineral wool, for example glass wool, rock wool or slag wool with a density of about 50 kg per m 3 or more and with a proportion of binder of about 0.5% by weight or more.
  • the partitions or bulkheads constructed from these components have suitable dimensions, for example of 600 mm ⁇ 2400 mm with a thickness of approximately 50 mm. Although components of this type have satisfactory strength, they have unsatisfactory low sound insulation values. It has therefore been proposed to assemble the core plate from two core layers of porous material. The core layers are held together by spacers and the cover plates are attached to the outer surfaces of the core layers. Because of the spacers, a cavity or air space is formed between the core layers. The cavity or the air space increases the sound insulation values, but on the other hand the strength of the component is deteriorated to an extent that is no longer acceptable, since the core layers only to a certain extent Extent of compressive forces and other loads between the cover plates.
  • the invention is based on the object of creating a component which has good strength and significantly higher sound insulation values than known components of the same thickness in the manner of sandwiches.
  • the object is achieved according to the invention in that a solidification and / or reinforcement layer is applied in whole or in part to the surfaces of the sound-insulating material lying after the cavity or air space.
  • the strengthening and / or reinforcing layer can be formed, for example, from paper, film or fiber material. A much more stable component is obtained if the applied hardening and / or reinforcing layer is selected so that it can absorb tensile forces. At the same time, higher sound insulation values and a significant reduction in the resonance frequencies of the component are achieved.
  • the consolidation and / or reinforcement layer can also consist of metal foil, for example aluminum foil.
  • metal foil for example aluminum foil.
  • Such a film leads to a greater fire resistance of the component, which is particularly important if the component is used in ships. In addition, the remains due to the metal foil
  • the temperature of the component on the side away from the possible fire is very low. Even when using glass fiber material, a component with greater fire resistance is achieved, at the same time making it easier to stick or bake on the core layers.
  • a component with greater fire resistance is achieved, at the same time making it easier to stick or bake on the core layers.
  • two core layers of mineral wool which are composed of narrow strips, higher sound insulation values are achieved in relation to the higher resonance frequencies of the component than if the core layers consist of mineral wool panels.
  • FIG. 1 shows a component according to the invention
  • FIGS. 2 and 3 show measurements of the sound insulation for a known component for wall structures
  • FIGS. 4 to 9 show measurements of the sound insulation for a component according to the invention.
  • Figure 1 shows an embodiment of a component according to the invention.
  • a core layer 2 is glued or baked on a cover plate 1.
  • the core layer 2 can consist, for example, of a mineral wool containing a binder, with a specific weight of about 150 kg / m 3 and with a binder content of about 1% by weight.
  • Between the cover plates 1 and along two against each other Overlying sides 3 strips are arranged. If necessary, these strips have longitudinal grooves 4 with the dimensions 15 mm x 15 mm.
  • the cover plates 1 are attached to the strips 3 by gluing or in another known manner.
  • the strips 3 can be formed from metal moldings or from wood or from mineral wool which is impregnated with a binder, for example with phenol-formaldehyde resin or water glass.
  • the strips have a thickness which is greater than the thickness of the core layers 2 taken together, so that a cavity or air space 5 is formed between the layers 2.
  • the strips can have a cross section of 47.4 mm ⁇ 47.4 mm, for example, and the layers 2 can have a thickness of 22 mm, for example.
  • the cover plates 1 can be steel plates with a thickness of approximately 0.7 mm. But they can also consist of plastic or wood. If the core layers 2 consist of mineral wool containing binders, these layers can be in the form of plates, with a fiber direction preferably parallel to the surfaces of the cover plates 1.
  • the core layers 2 can also be formed from lamellae, which are made from strips of binder containing mineral wool are composed, each strip or lamella being rotated by 90 ° about its longitudinal axis in such a way that the fiber direction is preferably perpendicular to the surfaces of the cover plates
  • the lamps can be arranged both vertically and horizontally.
  • the upper and / or lower end of the cavities 5 of the components can be closed with mineral wool.
  • a solidification and / or reinforcement layer 6 is applied to the surfaces of the core layers 2, which lie after the cavity 5.
  • This layer 6 can consist of paper, plastic film, metal foil or glass fiber material.
  • Figures 2 to 9 show the result of sound measurements on walls, which are made up of components and which are commercially available under the designations DS / ISO / R 140 and DS / ISO / R 717.
  • FIG. 2 shows the result of the measurements of the sound insulation in decibels for a wall which is made up of known components with a cavity 5. The results are plotted in the form of a curve in FIG.
  • the cover plates 1 are steel plates 0.7 mm thick, which are glued to the strips 3. Each bar has the dimensions of 47.4 mm x 47.4 mm x 2400 mm and consists of mineral wool containing lamellar binders with a specific weight of around 300 kg / m3.
  • a core layer 2 of lamellar mineral wool is baked or cemented onto the cover plates 1, with a specific weight of approximately 150 kg / m 3 and a thickness of approximately 22 mm, a cavity of approximately 2 mm being obtained.
  • the individual components are connected to one another with steel tubes, which have the dimensions 15 mm x 30 mm x 1.5 mm and are inserted in the grooves 4.
  • FIGS. 4 and 5 show measurements similar to those according to FIGS. 2 and 3 for a similar wall construction, but with Rutex glass fiber material which is glued to the surfaces of the core layers 2 lying after the cavity 5.
  • R 22.8 dB.
  • Figures 6 and 7 show measurements similar to those of Figures 4 and 5 for a similar wall, but the Rutex glass fiber material has been replaced by an aluminum foil of 0.05 mm.
  • FIGS. 8 and 9 show measurements similar to those according to FIGS. 4 and 5 for a similar wall, but here the lamellar mineral wool of the core layers 2 has been replaced by mineral wool plates with the same specific weight.
