Definitions

  • the invention relates to a cavity floor, comprising a profiled intermediate floor, which is arranged between an upper and a lower floor and is plate-shaped, the intermediate floor having pot-shaped depressions which are connected to one another by essentially flat edge regions.
  • Such a cavity floor is known from DE 36 37 987 A1.
  • the previously known cavity floor has a screed-filled and covered profiled floor film with truncated cone-shaped support feet, the floor film adapting to unevenness in the sub-floor and being accessible.
  • the floor film forms a formwork for the screed material to be applied, which forms the top floor.
  • the floor film is plate-shaped and as thin as possible, so that adjacent film plates can be placed loosely one above the other at their edges without any steps occurring in the screed layer.
  • the invention has for its object to develop a cavity floor of the known type such that internal stresses in the screed, which forms the top floor, are avoided and that the screed has a shorter drying time.
  • the cavity floor is also said to have improved impact sound insulation.
  • the depressions are filled with a sound-absorbing filler.
  • the sub-floor mostly consists of concrete, to which liquid screed material is applied to create the top floor, with the interposition of the intermediate floor.
  • the intermediate floor is accessible so that the viscous screed material can be smoothed out if necessary.
  • the intermediate floor is formed by a floor film made of polymeric material, which can preferably be produced by deep drawing.
  • the filler within a depression preferably has a load capacity of at least 4000 N. This ensures that the floor film can be walked on even if its thickness is less than 1 mm.
  • the filler has good inherent stiffness and can therefore withstand high loads.
  • the force acting on the intermediate floor is essentially absorbed by the filler.
  • the filler can be held in the recesses in an adhesive and / or form-fitting manner.
  • the filler interlocking with the adjoining surfaces of the floor foil during curing and thereby being held in its position in a form-fitting manner.
  • the filler and the openings of the connections adjacent edge areas are formed flush with the surface.
  • the accessibility of the intermediate floor is made considerably easier by such a configuration.
  • the edge regions can each be provided with at least one bead in order to improve their dimensional stability, at least two beads preferably being used which intersect one another at an angle of essentially 90 °.
  • the increased dimensional stability makes it easier to lay the intermediate floor on the sub-floor.
  • the filler is preferably formed by a PU foam.
  • the bulk density of the filler is 50 to 120, preferably 60 to 100 kg / m3 for most applications.
  • Such a filler has a comparatively high load-bearing capacity, prevents screed from penetrating into the recesses and provides good impact sound insulation when walking on the cavity floor.
  • the filler can also be formed, for example, by a one-piece rubber cork body, which is inserted into a depression and is adhesively connected to it, for example.
  • the rubber cork bodies preferably consist of recycled components that are pressed together.
  • the advantage here is that the mezzanine floor is particularly economical to manufacture from an economic point of view.
  • the depressions are each designed to match and that the ratio of the largest diameter and height is 0.6 to 1.8, preferably 0.8 to 1.2. Due to the essentially square design of the depressions when viewed in cross section, the intermediate floor has a high degree of load-bearing capacity, and buckling of the depressions is reliably avoided even when transverse forces are introduced, for example when walking on the intermediate floor to apply the screed.
  • a further improvement in the mechanical strength and load-bearing capacity can be achieved in that the depressions are frustoconical and are provided with stiffening ribs which extend along the entire height of the depressions and are evenly distributed in the circumferential direction.
  • the recesses which taper in the shape of a truncated cone in the direction of the subfloor also result in a relatively enlarged cavity for laying connecting cables and hoses in comparison to recesses which are essentially cylindrical. Due to the stiffening ribs evenly distributed in the circumferential direction, the material thickness of the intermediate floor can be further reduced with a given minimum load capacity.
  • a impact silencer can be arranged on the side of the bottom of the recesses facing away from the openings. It is also advantageous that slight unevenness in the underbody can be bleached out due to the elastic flexibility of the impact muffler.
  • the arrangement of the impact silencers ensures that footfall or structure-borne noise is decoupled, since the floor covering only touches the screed. The entire intermediate floor and the upper floor formed by the screed are supported on the underbody only by the impact silencers.
  • the impact silencers preferably consist of a closed-cell foam body with a density of 20 to 60, preferably 25 to 50 kg / m3 and have a pore number of at least 50, preferably 70 ppi. ppi indicates the number of pores over a 1-inch length.
  • the impact muffler covers the floor substantially completely, the impact muffler preferably having the shape of a regular hexagon.
  • the advantage here is that the impact silencer through its full surface Coverage of the floor is only exposed to a comparatively low surface pressure and therefore relaxation phenomena that impair impact sound insulation are avoided.
  • the shape of the regular hexagon is particularly advantageous from a manufacturing and economic point of view. Thanks to the hexagonal geometry, the impact silencers can be made absolutely waste-free.
  • the impact silencers are preferably glued to the bottom of the depressions in the intermediate floor and have a thickness of at least 2, preferably at least 5 mm. The good performance properties of the mezzanine floor with regard to decoupling impact sound remain unchanged throughout the entire service life.
  • the intermediate floor can be formed by at least two separately produced individual elements, which can be fixed to one another by at least one fastening device.
  • the individual elements can have external dimensions that correspond to the euro pallet size, so that an optimal transport area allocation is guaranteed when loading by truck and / or train.
  • the fastening device can be formed by a push button system in which at least one cup-shaped bulge of the first individual element can be brought into engagement with at least one congruently shaped recess or recess of the second individual element.
  • the sub-area of the overlap of one of the individual elements facing the sub-floor can be provided with a substantially right-angled shoulder, the thickness of which corresponds to the material thickness used for the sub-area of the individual element which faces the top floor.
  • Fig. 1 a section of a cavity floor is shown in a cross-sectional view.
  • FIG. 2 the intermediate floor of the cavity floor from Fig. 1 is shown cross-section as a single part, two adjacent individual elements of the intermediate floor are shown before their assembly.
  • Fig. 3 the intermediate floor is shown in a view from the direction of the sub-floor.
  • FIG. 4 shows two exemplary embodiments for the design of stiffening ribs which extend along the height of the depressions and are distributed uniformly in the circumferential direction.
  • a section of a cavity floor is shown in a cross-sectional view.
  • the cavity floor consists of an upper floor 2 designed as a screed, which is supported by an intermediate floor 1 on a sub-floor 3 made of concrete impact sound decoupled.
  • the intermediate floor 1 consists of several individual elements 1.1, 1.2, which are designed as deep-drawn floor foils.
  • the floor film 7 has a multiplicity of cup-shaped depressions 4 which are connected to the surface by a substantially flat edge region 5 which adjoins the openings 8 of the depressions 4.
  • the depressions 4 are filled with a sound-absorbing filler 6, which in this exemplary embodiment consists of a PU foam and has a density of 80 kg / m 3.
  • the foam has good inherent rigidity and can take a load of around 4000 N per well 4.
  • the depressions 4 have a surface profile on the inside facing the filler 6, with which the filler 6 interlocks positively during its solidification.
  • the depressions 4 are dimensioned in this embodiment such that the ratio from the largest inner diameter 10 of the recess 4 and the height 11 is one.
  • the floor film 7 is provided on the side facing the sub-floor 3 with impact mufflers 14 which are adhesively connected to the floors 13 of the depressions 4.
  • the plate-shaped impact silencers 14 consist of a closed-cell plastic body and cover the floor 13 essentially along its entire extent.
  • the filler 6 within the depressions 4 extends into the area of the openings 8 of the depressions 4 and is flush with the edge areas 5.
  • the reference number 9 denotes beads in the edge region 5, which are provided to improve the dimensional stability of the intermediate floor 1.
  • the second individual element 1.2 has a right-angled shoulder 19 which corresponds to the material thickness of the edge area 5 of the first individual element 1.1.
  • the push button system 16 is shown in a top view. It can be seen that the depression or recess 18 of the second individual element 1.2 is designed as an elongated hole, while the bulge 17 of the first individual element 1.1 has a circular shape. When connecting the bulge 17 to the depression or recess 18, manufacturing-related dimensional tolerances can be compensated for.
  • the screed is distributed over the surface of the intermediate floor 1 and forms the upper floor 2.
  • the impact silencers 14 cover essentially the entire bottom 13 of the depressions 4 and are designed in the form of a regular hexagon.
  • the impact silencers 14 consist of a closed-cell foam body and are glued to the floor 13.
  • the frustoconical depressions 4 have beads 9 which extend along the entire height 11 of the depressions 4 and are distributed uniformly in the circumferential direction.
  • the stiffening ribs 12 are essentially trapezoidal in FIG. 4.1; 4.2, the stiffening ribs 12 have an essentially triangular cross section.
  • the load capacity of the intermediate floor 1 is significantly increased by the stiffening ribs 12.
