Definitions

  • the present invention relates to a floor deck for a multi-storey building. Moreover, the present invention also relates to the use of the floor deck in buildings having two or more storeys.
  • the first category of sound is airborne sound, for example speech in general, including speech and sound from televisions and other types of media sources and also sound emanating from domestic appliances such as vacuum cleaners, food processors etc.
  • the second category is sound originating from contact with the building itself, for example sound emanating from the contact between parts of the building e.g. the floor and people, for example people walking.
  • the latter category can also be described as impact sound. In particular, when the people living in apartments or working in offices people in the apartments or offices generate sound from footsteps.
  • This second category of sound also includes sound originating from furniture used on a daily basis, for example chairs being repositioned.
  • the thickness of the floor deck is defined as the distance from the first surface layer side to the second support side of the supporting layer.
  • the floor deck may be delivered at the construction site as a cassette. Additional layers may be added to the cassette on site. For example, an additional layer may be added to the second support side of the supporting layer. In this way, it is possible to adjust the thickness of the floor deck as per requirements on site.
  • planks may be made from wood or wood fibre.
  • planks may be glued together.
  • planks may be combined into plank sections, the plank sections being combined to form a supporting unit.
  • plank sections may be combined by a joining element such as metal brackets or pieces of wood.
  • the plank sections may be combined to each other by tilted fastening means such as screws or nails.
  • the screws or nails may be tilted in order to spread the load on the local areas of the plank sections.
  • the fastening means are inserted at an angle of approximately 45° from the vertical direction.
  • the fastening means connection is inserted in the one plank section and continued into the neighbouring or abutting plank section. This may be continued until the desired size is achieved.
  • the plank sections may comprise an overlapping section such that fastening means, for example screws or nails may be inserted substantially in a perpendicular manner to the plank sections in order to combine two neighbouring or abutting plank sections.
  • fastening means for example screws or nails
  • the neighbouring plank sections may also be held together by glue alone or glue in addition to the fastening means.
  • plank sections may have an extension measured perpendicularly over the wide side of the plurality of planks of 500mm-2000mm or 750mm-1750mm or more preferred 1000mm-1500mm.
  • the floor deck may comprise an intermediate layer placed between the surface layer and the second layer.
  • the intermediate layer may be made from chip wood, cross-laminated wood, composites or similar.
  • the intermediate layer may comprise floor heating, for example tubes for waterborne floor heating. In this way, it is achieved that both the floor heating system and the material of the intermediate layer add to the sound dampening effect.
  • the intermediate layer may be made of chipboard. In this way, a rigid layer that is dimensionally stable is achieved.
  • the second layer may comprise two or more individual layers.
  • the second layer may comprise two or more individual layers.
  • the second layer may be 25-95mm or 35-75mm or 45-55mm.
  • the second layer may be made of mineral wool such as Rockwool or Isover. In this way, a sound dampening effect is achieved.
  • the supporting layer may be affixed to the walls of the building by brackets.
  • the supporting layer may rest on the inner wall of the building.
  • the supporting layer may be glued laminated wood.
  • the glued laminated wood (abbreviated as glulam) may be made of smaller planks or smaller pieces of lumber. These may also be called laminating stock or lamstock.
  • the height of the supporting layer may be 100mm-500mm or 125mm-400mm or 150mm-300 mm.
  • the glued laminated wood may be made of smaller planks or smaller pieces of lumber. These may also be called laminating stock or lamstock.
  • laminating stock or lamstock The general idea of glulam is the possibility to use smaller pieces of lumber to form large sections. This technique does not affect the sound dampening capabilities of the wood.
  • the height of the supporting layer may be 200mm.
  • the supporting layer may span up to approximately 7 metres from the first end to the second end of the planks or combined lumber pieces. The span may be longer than 7 meters.
  • the second side of the supporting layer may have an additional layer comprising at least one layer of gypsum boards.
  • an additional layer comprising at least one layer of gypsum boards.
  • the additional layer may be made of gypsum.
  • the thickness of the additional layer may be 1mm-200mm or 13mm-180mm or 26mm-160mm.
  • the additional layer comprises two layers of gypsum. Each layer of gypsum may be 13mm. In this way, an additional layer having a different sound dampening effect than wood is achieved. Further, the gypsum provides a higher fire resistance than wood.
  • the additional layer may comprise a wooden structure to which a number of gypsum layers are attached. In this way, it is achieved that a volume is created between the supporting layer and the gypsum layers of the additional layer. In this way, it is achieved that the volume is dampening airborne sound.
  • the supporting layer may comprise insulation.
  • insulation using e.g. brands as Rockwool or Isover may improve fire resistance.
  • the supporting layer may comprise sound dampening elements.
  • sound dampening elements and/or vibration dampening material may be made from viscoelastic material or rubber.
  • the sound dampening elements may be arranged at least at some or at all points of contact with the walls or brackets supporting the supporting layer.
  • the surface layer may be made from gypsum.
  • the surface layer may have a thickness of 13-50mm.
  • the layers above the supporting layer of the floor deck may be floating. In this way, it is achieved that no sound is transferred from layer to layer via any connecting means such as nails or screws.
  • the present invention relates to the use of the floor deck in buildings having two or more storeys.
  • the floor decks reduce the sound migration or transfer as well as being strong enough to be part of the structural part of the building as a whole.
  • Fig. 1 shows a number of floor decks 1 arranged in a multi-story building 2.

  • Reference numerals 68 and 68' refer to a feature shown only in Fig. 3D .
  • the feature of gypsum layers 68 and 68' is also shown in Fig. 1 , Fig. 3A and Fig. 4 but not marked with reference numerals.
  • the floor deck 1 comprise a surface layer 10 having a first surface layer side 11 and a second surface layer side 12.
  • the surface layer 10 may be made of gypsum or similar.
  • an intermediate layer 40 having a first intermediate layer side 41 and a second intermediate layer side 42 is positioned between the surface layer 10 and the second layer 20.

  • the second layer 20 is divided into two individual second layers 20, 20'.
  • the second layer 20 may be one layer.
  • the second side 22' of the second layer 20' faces the first support side 31 of the supporting layer 30.
