Definitions

  • the present invention relates to a floor system, which is laid on a raised hollow floor system or floating, comprising a screed, in particular a calcium sulfate / Anhydritffanestrich or concrete screed according to the preamble of claim 1.
  • hollow floors refers to a system floor construction with flat support layer, which is mounted on special substructures to form a cavity between the base layer and the raw ceiling for carrying out installations for telecommunications, electrical connections, heating, ventilation and so on.
  • the base course often consists of poured screed mortar on a thin lost formwork.
  • the lost formwork is usually made of wood, gypsum fiber boards, cement fiber boards or special plasterboard. These formwork panels rest on supports made of metal or mineral materials.
  • One variant is the so-called dry hollow floor with base layers of board materials.
  • Composite screed systems are also known (see eg EP 2 374 768 A2 ).
  • the composite screed is directly on the raw concrete and is connected to this force-fit. Since all forces are dissipated directly into the subsoil, the load bearing capacity is limited by the subsurface, usually a concrete pavement, or by the compressive strength of the screed.
  • the main problem in the production of a composite screed is the correct substrate preparation, so that there are no hollow layers. Especially with high dynamic loads a composite screed has to be chosen. Calcium sulphate screeds should not be laid in a composite, as in the absence of heating the necessary residual moisture content of 0.5 CM% can generally not be achieved and a reaction with the concrete (ettringite formation) takes place.
  • the problem here is the higher time required with the result of a construction delay and the higher material requirements.
  • a separating layer of foil or soda kraft paper is proposed.
  • the screed and the separating layer do not form a composite.
  • Nonwoven is a sheet of textile fibers.
  • the fibers are mechanically, thermally or chemically solidified.
  • EP 1 905 920 A1 discloses a floor composite body of a floor heating system with an insulating layer having open-topped channels in which heating pipes and Winnipegleitbleche are arranged, wherein the shallleitbleche also cover the lying between the channels surface of the insulating layer.
  • the system further comprises a mineralized mortar or screed layer.
  • FR 1 521 596 A shows panels and cladding panels, with independent external cladding elements, for floors and partitions.
  • a reinforcement of the cover member may consist of a grid of metal wires or of glass fibers.
  • WO 2006 084 637 A1 discloses a drainage sheet material or sheet material for drainage or deaerating laying of tile coverings exposed to weathering on an applied mortar or adhesive layer.
  • a wasserduchmaye nonwoven layer is used.
  • US 9,186,869 A describes a floor system consisting of a slab floor, a floor covering and a composite underlay extending between the slab floor and the floor covering.
  • the composite backing may include, for example, one or more set gypsum layers with embedded fiber mats.
  • An outer plastic coating is mechanically attached to an underlying gypsum layer.
  • FR 2 349 420 A1 shows a sheath with a textile layer for a bottom plate, wherein the sheath is to be weather-resistant and resistant to aging and seals the plate material against liquids, water vapor and gas.
  • DE 20 2008 002 867 U1 discloses plate-shaped components such as wall, ceiling or floor panels, wherein the plate-shaped components are provided on one or both sides with a coating having a support layer with a water and Water vapor-tight aluminum lamination is provided, wherein on the side facing away from the aluminum lamination a plastic film is arranged.
  • the object of the present invention is to obviate the disadvantages of the prior art, and thus to provide a flooring system which, in contrast, provides increased load-bearing capacity, improved drying behavior, simple processing and increased soundproofing.
  • Static activity means: The breaking stress is considerably increased by the bond between the screed and the reinforcement (fleece) similar to the reinforced concrete. The higher tensile strength of the nonwoven in the tensile zone increases the overall strength.
  • Textile layers are morphologically determinable, fabricated structures of spinnable, length-limited fibers and (or) drawn, endless fibers that exhibit spinnability as a property. These may be fabrics made of fibers such as nonwovens, felts and wadding, as well as threads such as braids, fabrics, nets and knitted fabrics.
  • glass fibers due to their mechanical stability and their low cost.
  • suitable materials are e.g. certain stable polymers or mineral wool.
  • composites such as glass fiber reinforced plastic, short fiberglass are possible, as far as they have a sufficient stability.
  • This layer is preferably made of fiberglass textile, which is formed in a particularly preferred embodiment as a glass fiber fleece.
  • the screed is applied in the liquid state to the textile layer.
  • the glass fiber fleece combines with the floating screed, in particular Anhydritf punestrich, and acts statically like a drawstring in the tension zone of the multi-layer systems. This is because the individual fibers are enclosed by the screed and thus form a particularly stable composite material. This allows the system to absorb significantly more stresses, so that the screed thickness can be significantly reduced with the same performance. Due to the increased rigidity of the system, the soundproofing is also increased.
  • the fleece is "bulky” and separates the screed despite the connection of fleece and screed from the ground (suspension effect). This causes a footfall sound insulation.
  • This impact sound increase is achieved in particular by increasing the stiffness of the screed-fleece composite by the statically effective textile layer and not or not only by the spring action of a drainage plate. By increasing the stiffness of the impact sound is reflected in the plate.
  • the textile layer is impermeable to liquid water and permeable to water vapor.
  • Their water vapor permeability according to DIN 52165 is between 0.01 m and 1.0 m, preferably 0.01 m to 0.1 m diffusion-equivalent air layer thickness.
  • the solidification process of the individual fibers to the layers have effects on the properties: There are different solidification processes, in particular the bonding of single fibers, thermal consolidation, etc.
  • the installation of the textile layer takes place in a hollow floor system as follows: First, the hollow floor sheets are surrounded with the textile layer. This can be done by wrapping without further attachment means. But it is also possible a fastener such as glue, glue, resin or similar. to use.
  • the hollow floor slabs are laid flat next to each other (on supports or the like).
  • the overhanging textile layer protrudes beyond the gap to the adjacent plate. This overlap causes a closed surface to emerge. Subsequently, liquid screed is poured onto the system. The overlap prevents the flow of screed between the panels.
  • the screed connects to the textile layer, which in turn is connected to the material panels. Furthermore, the plates are circumferentially coated with fleece, so that in the tensile zone of the material plate, the tensile strength is increased.
  • the combination of glass fiber, material plate, glass fiber and floating screed results in a multi-component composite system, which increases strength by increasing stiffness (EI) and limiting deflection. Superfluous projections can be folded over or cut off.
  • the textile layer has a weight per unit area (grammage) of between 50 g and 500 g / m 2 . Higher grammages are better in terms of sound insulation but are less permeable to water.
  • Their layer thickness is 1 to 30 mm, preferably 1.5 to 25 mm.
  • the textile layer is formed of alkali-resistant fibers. This is especially important in concrete screeds. Particularly suitable here are alkali-resistant glass fibers, but also alkali-resistant polymers or composite materials of these substances.
  • hollow floor panels are covered with the textile layer.
  • These hollow floor slabs may be, for example, plasterboard, wood, cementitious slabs. Other suitable materials are also possible.
  • cement-bonded slabs are preferably used with alkali-resistant nonwovens wrapped in them. Together with the screed it is thus a 3-component composite system.
  • the floor system has a door separating element.
  • This forms a dividing strip between different rooms. It is preferably formed fiberglass strips vertically below the door leaf. When applying the screed this flows from both sides against the separating strip and connects to the glass fiber separating strip.
  • the door separating element is so thick that the two screeds do not make a direct connection with each other - ie can separate and expand. The stiffness in this area is increased because the vertical fleece acts as a kind of stiffening disc.
  • the floor system has at least one edge insulation strip.
  • This is preferably made of glass fiber and can be attached circumferentially with a kind of self-adhesive strip on the wall.
  • the strip is so thick that the screed and the wall are separated. The screed makes a connection with the fleece and thereby obtains an increase in the strength in this area.
  • the effect of the Randdämm- and door separation strips (space separation), or expansion strips of textile layer is the following:
  • the edge insulation strips are such a thickness that they combine on the one hand with the floating screed and on the other hand are so thick that they sound the floor system separates from the wall.
  • the expansion strip the strip is so thick that both sides connect to the fleece but both screed sides do not form a bond with each other.
  • the screed can expand without causing tensions between the screeds.
  • the stress by, for example, swelling or thermal expansion is absorbed by the cavity (elastic crush zone by the thickness of the strip).
  • Both the edge insulation and door separation strips can also consist of several textile layers. This can be advantageous for laying.
  • the screed is here separated from each other or against other components, but due to the separation of the edge insulation strip, since the material so far only PU foam, foil o. ⁇ ., Record no additional tension.
  • the fibers of the separating element connect with the screed and achieve a significant increase in stress at the relevant weak points of the system (edge or door separation areas) and thus an increase in strength in this area. Furthermore, the tearing of the base tile seam, this can be a silicone seam, by lowering the screed in the edge area, thereby prevented. Thus, the vulnerability to the "strong point".
  • At least one heating loop is introduced above, below or into the layer of textile layer but below the screed layer. This enables a stable installation of a floor heating system.
  • At least one heating loop and molded parts are introduced above or below the textile layer and under the screed layer.
  • the heating loops can also be encased by this layer in the case of a textile layer which consists of a thermally stable material, such as glass fiber. i.e. are inside the textile layer.

  • the fleece connects to the screed again. This makes the system more resilient.
  • the screed mass can be significantly reduced, which additionally reduces the drying time.
  • cement-bonded panels about a loosely laid textile layer, preferably a nonwoven, and about anhydrite screed.
  • the screed connects to the textile layer.
  • the anhydrite screed does not combine with the cement-bonded plates, so that the Etringitt Bear is prevented.
  • the overall dispute is higher compared to conventional systems.
  • the hollow bottom panels of the floor system are completely surrounded by a textile layer of glass fiber fleece and / or glass fiber reinforced plastic.
  • they can have an overlap of at least 20 mm, preferably at least 30 mm.
  • hollow bottom plates are surrounded in a floor system according to the invention with a textile layer of glass fiber fleece and / or glass fiber reinforced plastic.
  • the textile layer forms an envelope around the hollow bottom plate, in which a maximum of one side is open.
  • the hollow floor panels can be easily wrapped because the textile layer is prefabricated.
  • This shell may have an open edge for receiving the hollow bottom plate. It encloses the hollow bottom plate so completely or completely minus an open edge.
