Definitions

  • the invention relates to a carrier and a corresponding hollow box module for load-bearing ceilings made of wood for buildings, as well as a ceiling and a building.
  • the attachment of decoupling strips from z. B. elastomers for vibration isolation of the ceiling-wall joints is known in principle.
  • the ceiling span in single-family houses is up to approx. 6 m, in multi-family houses 8 to 12 m and in high-rise buildings more.
  • the beam cross-sections range from 60 x 140 mm to 120 x 380 mm.
  • the invention is therefore based on the object of reducing the effort on the construction site when erecting a building.
  • a carrier according to the invention is characterized in that an integrated decoupling element is provided in order to effect vibration isolation.
  • the invention makes use of the fact that a reproducible quality can be guaranteed by attaching the decoupling elements in the manufacturer's works. In addition, the effort on the construction site is significantly reduced because subsequent attachment can be avoided.
  • the above limit values for sound transmission in buildings include values for direct transmission together with flanking transmission via the joints of joined components.
  • the "mass-spring-mass" principle must be applied when insulating the direct transmission.
  • effective vibration insulation i.e. decoupling of the joints, is required for the insulation of flank transmission.
  • the decoupling element can also be surrounded by wooden parts on the outside, so that it can hardly be damaged and further assembly, possibly gluing with other parts, a plate or the like, is simplified.
  • the decoupling element can have a mechanical connection to the other components of a ceiling or a hollow box module as a building block of a ceiling via a lamella or a beam.
  • a thin lamella is characterized as a coupling element and possibly a covering element of the decoupling element in that it protects it from mechanical damage and can itself serve as a well-defined transmission element for mechanical impulses during assembly.
  • the flat elements, such as the decoupling element or lamella can be in uniform contact with one another over the entire surface on the respective side. So it can Decoupling element are also loaded over its entire surface, absorb the pressure over the largest possible area and dampen it particularly well.
  • the decoupling element is arranged continuously or only interrupted by cavities over the entire surface, the damping effect is increased.
  • a ceiling can consist of a series of parallel beams which are in contact with one another over the entire width. This structure is fundamentally very stable with regard to mechanical loads.
  • hollow box modules in which the carriers are arranged parallel but spaced apart, so that cavities are formed in between, which insulate, under certain circumstances can also be filled with filling/insulating material. In this way, thermal insulation can also be integrated in an advantageous manner.
  • the hollow box modules can also have high bending moments.
  • a thicker beam or a thicker stack of slats can also be arranged on at least one side of the decoupling element in order to serve as a supporting component and to be able to absorb greater loads.
  • a thicker beam or a thicker stack of slats can also be arranged on at least one side of the decoupling element in order to serve as a supporting component and to be able to absorb greater loads.
  • the components In order to stabilize timber construction, it can also be ensured that the components have the same fiber directions as one another.
  • FIGS 1 and 2 are wooden beams 1, 4 with integrated decoupling element 5 for load-bearing ceilings in timber construction for buildings.
  • the carrier 1 consists of a beam 2 and a lamella 3 or in the case of a glued laminated timber carrier 4 (BSH carrier), cf. 2 , made of several lamellas 3 with a materially, positively or non-positively connected decoupling element 5.
  • BSH carrier glued laminated timber carrier 4
  • This hybrid construction manufactured continuously in a purely industrial manner, effectively insulates the structure-borne noise bridges, so that flank transmission is also prevented.
  • the carrier 7 consisting of a beam 2 and a slat 3 with an integrated decoupling element 5.
  • the beam 2 has the task of transferring the ceiling load to the walls within the permissible deformation values.
  • the lamella 3 has no primary static task, but serves to integrate the decoupling element 5 into the carrier 7, which can thus be used as a hybrid rib 7, for example in a hollow box module 6.
  • the carrier 1 with integrated decoupling element is suitable as an individual component of a beam ceiling or solid wood ceiling and as an individual component of a hollow box module 6, as shown in 3 is shown for a complete blanket.
  • the spans of the load-bearing ceilings produced in this way are up to 20 m and can be used in single and multi-family houses and in high-rise buildings.
  • a glulam beam 4 is shown, consisting of a slat 3 arranged at the top and several lower slats 3 joined together to form a slat pack 8.
  • the slat pack 8 consisting of at least two slats 3 glued together, takes on the static requirements of the ceiling and the upper slat 3 the integration of the decoupling element 5.
  • the upper lamella 3 preferably has a thickness of approx. 20 mm and the lower lamella 3 has a thickness of 20 to 40 mm. Measurements above and below are also applicable.
  • the hollow box module 6 consists of at least two ribs 7 and at least one plate 9, which are connected to one another in a material, non-positive or positive manner.
  • the plate 9 is included in the static calculation in addition to the rib 7 .
  • the Figures 4-8 each show variants of load-bearing ceilings 10, consisting of different types of compilations of the individual elements from the Figures 1-3 .
  • FIG. 4 shows a ceiling 10 from a series of beams 7, each composed of a sandwich of lamella 3, decoupling element 5 and beam 2.
  • the carriers 7 are lined up in parallel, so that the decoupling element 5 forms a continuous layer through the ceiling 10 .
  • figure 5 shows a ceiling 10 in which the carriers or ribs 7 are spaced from each other (like ribs) on the plate 9 are arranged.
  • FIG. 9 shows a building section G, consisting of three floors 11, separated by load-bearing ceilings 10, consisting of hollow box modules 6.
  • the picture shows the possible sound transmission paths:
