Definitions

  • the invention relates to a component for sandwich-type wall constructions with at least one inner cavity or air space, furthermore with outer cover plates and with sound-insulating material, preferably a porous material, which is attached to the surfaces of the cover plates lying after the cavity or air space .
  • a component of this type is known from FR-A-2124354.
  • an additional layer can be applied to the surfaces of the sound-insulating material to be located after the cavity or air space, but this is merely designed as a boundary or separating layer and nothing is said about the nature and function thereof.
  • Components for wall structures of this sandwich type 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 be as thin as possible in order to save space, but on the other hand they should also be as stable as possible and ensure great sound insulation.
  • the components which are 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 x 2400 mm with a thickness of about 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 this reduces the strength of the component to an extent that is no longer tolerable, since the core layers can only transmit compressive forces and other loads between the cover plates to a certain extent.
  • the invention is based on the object of creating a component which has good strength, significantly higher sound insulation values and, above all, high fire resistance, compared to 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 to be located after the cavity or air space and which consists of a metal foil or a glass fiber material.
  • a solidification and / or reinforcement layer is applied in whole or in part to the surfaces of the sound-insulating material to be located after the cavity or air space and which consists of a metal foil or a glass fiber material.
  • an advantageous embodiment of the invention results from the fact that the sound-insulating material consists of mineral wool lamellae, the lamellae being rotated through 90 ° about their longitudinal axis. In this way, higher sound insulation values are achieved in relation to the higher resonance frequencies of the component, compared to an embodiment in which the core layers consist of mineral wool panels.
  • 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.
  • Bars 3 are arranged between the cover plates 1 and along two mutually opposite sides. 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 that 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 consist of strips of binder containing mineral wool are composed, each strip or lamella being rotated through 90 ° about its longitudinal axis in such a way that the fiber direction is preferably perpendicular to the surfaces of the cover plates 1.
  • the slats can be arranged both vertically and horizontally.
  • 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.
  • FIG. 2 shows 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.
  • the test walls have a size of approximately 10.4 m 2 .
  • FIG. 2 shows the result of the measurements of the sound insulation in decibels for a wall that is made up of known components with a cavity 5. The results are plotted in the form of a curve in FIG. 3.
  • 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 lamellar mineral wool containing binders with a specific weight of around 300 kg / m 3 .
  • 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. 6 and 7 show measurements similar to those of FIGS. 4 and 5 for a similar wall, but the Rutex glass fiber material has been replaced by an aluminum foil of 0.05 mm.
