Definitions

  • the present invention relates to a flooring structure having improved footstep sound insulation, comprising beams.
  • the present invention specifically relates to footstep sound insulation, i.e. to reduce, on dynamic loading, the transfer of sound between two storeys and/or apartments.
  • dynamic loading relates to that type of loading which occurs as a result of footsteps on a floor.
  • a traditional flooring structure consists further of a floor and a ceiling.
  • insulating material In the actual flooring structure and between floor, ceiling and flooring structure, respectively, there are normally various types of insulating material.
  • battens for supporting any possible insulation between the beams and false ceiling panels.
  • the bearing wooden beams are secured in the structure of the building.
  • One object of the present invention is to reduce the footstep sound, i.e. to reduce the drawbacks inherent in traditional flooring structures as described above in the event of dynamic loading.
  • the flooring structure must satisfy the usual requirements as regards mechanical strength, structural sound insulation and airflow sound insulation, fire safety, etc.
  • the figures show substantially only the beams, the floor structure, included in the flooring, but a person skilled in the art will readily perceive that the flooring structure also includes floor, ceiling and various insulating layers.
  • the beams 1 are interconnected with the aid of floor panels 5 and ceiling panels 6. Also, in such a flooring structure, the individual beams co-operate via the panels so that footstep sound 4 is transferred from its entire surface towards adjacent areas.
  • the individual beams 1 are not dynamically joined together.
  • the ends of the beams are secured in the structure of the building.
  • the present invention is based on the feature that the bearing beams 1 of the flooring structure do not co-operate dynamically with one another in any significant manner.
  • the beams 1 are not interconnected with each other apart from at certain discrete points, for example bearing supports at the ends of the beams.
  • the beams 1 in the flooring structure according to the present invention lie considerably closer to one another.
  • a suitable rule of thumb in such instance has proved to be that the distance between the beams 1 should be less than the height of an individual beam 1.
  • a dynamic loading 3 When a dynamic loading 3 is applied on a flooring structure according to the present invention, only the beam or beams 1 which lie directly beneath the point of impact of the loading will be affected. The transfer of movement to adjacent beams is minimized. In such instance, the footstep sound 4 is only transferred via these directly affected-beams.
  • the flooring structure may be said to react locally in that it only emits sound immediately adjacent the applied dynamic loading 3.
  • the local reaction principle according to the present invention also applies to semi -homogeneous flooring structures without interconnected beams 1.
  • the beams 1 lie a distance from each other and insulation 7 has been placed between the beams 1.
  • This insulation 7 must have low shearing rigidity. If the insulation has too high shearing rigidity, there is a risk that the vibrations are transferred between the beams 1.
  • An example of suitable insulation material is mineral wool of low shearing rigidity.
  • the flooring structure reacts only locally to a dynamic loading 3.
  • the local reaction to a dynamic loading is attained in that the flooring beams in the flooring structure under consideration are provided with grooves which reduce torsional rigidity and compression rigidity at the anchorage point to the floor and/or ceiling panels.
  • the same effect is achieved with separate, grooved studs in accordance with the foregoing which are mounted on the upper and/or lower side of the flooring structure.
  • the floor may rest direct on the beams.
  • grooved studs 10 are placed between the beams 1,8 and the floor panels 5.
  • both beams 1,8 with and without grooves may be employed.
  • Wood wool panels absorb sound efficiently and transmit little sound compared with, for example, a plaster board.
  • the form of the flooring structure may be varied in many different ways without deviating from the inventive concept as herein disclosed. However, it is always important to ensure that, when one or more adjacent beams 1 are subjected to a dynamic loading, the transfer of the loading movement of the beam/beams to other beams in the flooring structure is minimized.
