Definitions

  • the invention relates to a decoupling mat, comprising a plurality of layers, which can be used for decoupling, sealing and impact sound insulation, and a structure comprising this decoupling mat.
  • pairings are for example concrete / wood or concrete / tiles, which are used in particular in new construction.
  • a wooden floor is often placed on old tiles or vice versa.
  • materials of this type are known to have different properties and so the different materials behave on externally applied loads and against temperature and humidity influences also different.
  • internal stresses occur, which expand or contract the materials differently in particular in the XY plane, ie horizontally, and thus produce distortions or cracks.
  • a structured plastic film is frequently used in which the structure on the upper side of the plastic film is formed from a multiplicity of identical, closely spaced and uniformly distributed cavities and webs extending between the cavities. On their underside, the cavities inevitably present as elevations and the webs as indentations.
  • This structured plastic film is laid during processing with its underside in a mortar bed and passed on top of it with a layer of mortar. Then comes the cover material. Due to their low material thickness and the large number of cavities, the plastic film is able to work in the XY plane and to absorb the stresses acting in this direction.
  • this plastic film is not sufficiently sustainable, because the sustainability of the plastic film results in the main from the structure of the plastic film with the raised webs on the one hand and the surveys on the other hand and the material thickness of the plastic film.
  • the narrow webs and the low material thickness do not guarantee sufficient stability.
  • the mortar applied on both sides also can not ensure a uniform pressure distribution, because the cavities and the interstices are kept relatively small and narrow and therefore can not be sufficiently filled with the mortar.
  • This decoupling web consists of a relatively rigid polyethylene web, which is provided on its upper side with square and dovetail undercut recesses and intervening, lattice-like webs. On the bottom of a carrier fleece is glued.
  • the polyethylene sheet is designed relatively thick and the webs have a large width. This makes the polyethylene sheet very stable.
  • the depressions in the surfaces are designed to be very large, which can easily be filled with mortar or an adhesive. These fillings are also very resilient and so the load on the floor spreads both on the polyethylene sheet as well as on the fillings. This decoupling path is therefore very resistant to treading.
  • the core of the decoupling system is an anchoring layer, which consists of a structural element with bars and evenly distributed between the grid bars cavities.
  • the cavities are filled with a mixture of quartz sand and a binder, which is introduced in the wet state either mechanically during the preparation of the decoupling and drainage system or manually during installation at the installation site. After curing of the binder there is an adhesive bond between the individual grains of quartz sand and between the entire quartz sand filling and the bars of the structural element.
  • This decoupling and drainage system is suitable for indoor use only conditionally, because it builds up too much in height.
  • z. B. with a tiled surface based on the valid in Germany ZDB leaflet "Instructions for the execution of seals in conjunction with linings and coverings of tiles and panels for indoor and outdoor” the system is not suitable because a composite seal with Help from z.
  • sealing tapes, etc. in the edge region of the system is not reliably possible, and thus it can lead to an infiltration of moisture.
  • the DE 20 2005 004 127 describes a carrier plate of foil-like plastic for a plate-covered floor construction.
  • the carrier plate is intended to serve for decoupling.
  • In the plastic film depressions are formed, whereby a plurality of chambers are formed.
  • Both sides of the carrier plate are provided with a net-like fabric or fleece.
  • the fabric or nonwoven on the side of the plurality of chambers is designed so that can be penetrate through the fabric or nonwoven into the chambers at the construction site when laying the support plate of the adhesive or mortar used.
  • the decoupling effect is not optimal, since the adhesive or mortar forms a unit in the chambers of the support plate with the floor covering.
  • the introduction of the mortar or adhesive in the chamber at the site is very laborious and it can continue to form air-filled cavities in the support plate, which reduce the compressive strength of the support plate and can even lead to a detachment of the covering.
  • Another disadvantage of the carrier plate is that it is less suitable for impact sound insulation. The sound is transferred from the floor covering by the adhesive or mortar via the chambers of the support plate directly to the substrate. This is a common problem of the prior art decoupling mats or decoupling sheets.
  • the EP 1726715 discloses an elastic pad for floor coverings, for example, floor coverings for sports facilities such as artificial turf, the pad a first laminar Structure and having a second laminar structure.
  • the laminar structures form cavities filled with granular elastic material.
  • the underside further comprises a nonwoven layer on both sides of the laminar structure.
  • Plastic foam sheets are usually first laid in a thickness of 3 to 20 mm on the floor and poured over a screed.
  • a common raw roof thickness is 160 mm, the screed thickness is generally 50 mm.
  • plastic foam boards are predominantly polyethylene plates use.
  • the floor / ceiling construction depends on whether screed is applied. In this case, a foil is placed over the impact sound insulation, so that the floating screed does not flow into the joints between the plates of the impact sound insulation and can form sound bridges.
  • the invention is therefore based on the object to develop a generic decoupling mat, which has both a high decoupling capability and a high load capacity. Furthermore, the decoupling mat should simultaneously allow excellent footfall sound insulation and constitute a composite sealing measure. Further, the mat should allow for vapor pressure equalization at the back of moisture and be easy and cost effective to manufacture.
  • the new decoupling mat eliminates the disadvantages of the prior art. From the multi-layered structure, in which the one-sided deep-drawn shapes are already filled with a filler, there is the particular advantage that the decoupling mat can be made completely factory and the cavities not only when laying with an adhesive or mortar must be filled.
  • the decoupling mat invention also fulfills the task of a composite sealing measure according to ZDB leaflet "Hints for the execution of Seals in combination with linings and coverings made of tiles and slabs for indoor and outdoor use. "Furthermore, this air ducts, which remain open on the underside, allow vapor pressure compensation in the event of moisture exposure and a reduction in impact sound.
  • the preparation of the plate can be done by simply filling the one-sided deep-drawn forms 5 of the second plastic film layer 3 with the filler 6 .
  • the binder is preferably a plastic-based binder which can form a solid bond with the second plastic film layer 3 and possibly the first plastic film layer 2 .
  • the binder may be a plastic which liquefies under the influence of heat so that it wets the entire surface of the individual grains of sand and all inner surfaces of the one-sided deep-drawn forms 5 of the plastic film 3 .
  • the plastic may further preferably be able to enter into a welded connection in the heated state and possibly under pressure with the plastic film 3 and cure during the cooling phase and to bond with the sand grains of the filler 6 and in particular polyethylene or an ethylene-vinyl acetate. copolymer.
  • the filler 6 can thus be glued in its entirety and continue with the plastic film 3 . Subsequently, the first plastic film layer 2 is applied.
  • the deep-drawn forms on 5 flat undersides 8 which are aligned parallel to the flat, contiguous base 4 and in a plane.
  • the undersides of the deep-drawn forms 8 correspond to at least 35% of the total area of the plastic carrier film. In this way, a high compressive strength of the decoupling mat can be achieved.
  • the first and second plastic film layers 2 and 3 may preferably be bonded together by gluing or thermobonding. It is particularly preferred if the filler 6 comprises a binder, wherein the filler 6 used is also applied to the flat, continuous base surface 4 .
  • the binder contained here can serve as an adhesive for bonding the plastic film layers 2 and 3. As a result, manufacturing costs can be saved.
  • the first fabric or nonwoven layer 1 and the first plastic film layer 2 are first connected to each other by gluing or thermobonding, particularly preferably by thermobonding and only subsequently the plastic film layers 2 and 3 are interconnected.
  • the second fabric or nonwoven layer 7 and the second plastic film layer 3 can also be bonded together by adhesive bonding or thermobonding, preferably by thermobonding.
  • the first and the second woven or nonwoven layer 1 and 7 of the layer ⁇ ) and ⁇ ) are a nonwoven fabric, a textile fabric, a fine mesh fabric or a fine mesh fabric.
  • the fabric or nonwoven layers 1 and 7 may comprise or consist of individual synthetic fibers or synthetic yarns.
  • the nonwoven fabric is preferably a nonwoven structure of polyester, polypropylene, or polystyrene. Furthermore, it may be a glass fiber fleece.
  • Nonwovens are understood to mean textile surface fabrics which comprise individual fibers or threads as entanglement. In contrast, fabrics, knits and knits are made from regularly arranged threads or yarns.
  • the woven or nonwoven layers are preferably designed such that they can easily be penetrated by a mortar or an adhesive and the decoupling mat can thereby form a firm bond with the substrate and the covering.
  • the second fabric or nonwoven layer 7 is designed so that it prevents penetration of a mortar or an adhesive into the cavities 10 . This makes it possible by the thus generated underside open air channels a vapor pressure compensation at the rear exposure to moisture.
  • the decoupling mat preferably has a load capacity of greater than 20 t / m 2 or a compressive strength of greater than 0.2 N / mm 2 .
  • the flexibility of the decoupling mat remains unaffected, because this results solely from the thickness of the plastic films 2 and 3 and the distance of the edges of the deep-drawn forms 9 on the flat, contiguous base to each other.
  • the distance of the edges of the deep-drawn forms 9 on the flat, contiguous base 4 to each other is at least 3 mm.
  • the geometry of the deep-drawn forms 5 in the horizontal cross section can be freely designed in many areas.
  • XY direction see FIG. 2 and 3
  • the geometry of the deep-drawn forms 5 in the horizontal cross section can be freely designed in many areas.
  • the decoupling mat is in particular a square or rectangular cross-section preferred. However, it may also be a round or ellipsoidal cross-section, wherein on a decoupling mat also different horizontal cross-sectional geometries can be realized side by side.
  • the maximum diameter 12 of the deep-drawn forms 5 in the XY direction on the flat, continuous base 4 should preferably be less than 25 mm.
  • the flexibility is therefore initially assumed, and from this an optimum film thickness for the plastic foils 2 and 3 is determined. With the strength of the plastic films 3 thus determined, the stability of the side walls 11 of the deep-drawn forms 5 can then be calculated. From the difference of the predetermined stability of the decoupling mat and the calculated stability of the plastic film can then determine the exact dimensions of the support feet.
  • the optimized decoupling mat saves material, processing time and ensures high functionality.
  • the plastic film of the second plastic film layer 3 has a thickness of 100 to 500 ⁇ m.
  • the plastic may consist of polyethylene or a copolymer of ethylene and vinyl acetate.
  • the high flexibility of the decoupling mat allows for rolling up and thus a space-saving transport to the construction site. It is excluded by the first plastic film layer 2 that the filler 6 can dissolve out during the transport or subsequent processing of the plastic film 3 and can be lost. Complete factory prefabrication also saves costs during on-site processing as it eliminates the need to manually coat a thin bed of mortar.
  • the second plastic film layer 3 has a thickness of 3 to 50 mm, preferably 5 to 15 mm.
  • the filler 6 consists of a bonded mixture of quartz sand and a binder, wherein a thermoplastic such as polypropylene or ethylene-vinyl acetate copolymer can be used as a binder.
  • a thermoplastic such as polypropylene or ethylene-vinyl acetate copolymer
  • This mixture has already been tested in practice as viable. It is particularly useful if the binder that is used for the bonding of the filler 6 , at the same time with the plastic film 3 is welded. This makes the manufacturing process effective, because both the bonding and the welding or the thermobonding can be made factory and in a single operation.
  • the adhesive is preferably a thermoplastic such as polypropylene or ethylene-vinyl acetate copolymer. Furthermore, it is preferred that at least two layers of the decoupling mat are connected by thermobonding.
  • the present invention relates to a structure, in particular for a plate-covered floor structure, wherein the decoupling mat according to the invention with the side on which the deep-drawn forms are applied to a substrate and the decoupling mat, an adhesive or mortar is applied, which optionally with Plates, especially with concrete blocks, natural stone or tiles is occupied.
  • the substrate may be, for example, concrete, screed or a tile and plate covering, wherein the decoupling mat is preferably connected by a mortar or adhesive to the substrate.
  • a substrate virtually any material is suitable.
  • decoupling mat according to the invention By decoupling mat according to the invention a very good impact sound insulation is achieved. Without being bound by theory, it is believed that this is achieved in comparison to the prior art decoupling mats, in particular by the separation of the filler 6 from the deposited coating by the first plastic film layer 2.
  • essential design of the decoupling mat formation of sound bridges is avoided. Sound bridges, ie vibratory connections between sound-producing components, such as those produced by walking on the floor covering, transmit the vibrations to the ground, where the sound propagates as structure-borne sound and may possibly propagate throughout the structure.
  • the combination of the first plastic film layer 2 with the first fabric or nonwoven layer 1 effectively avoids the formation of sound bridges.
  • the impact isolation (ISO 140-8) of ⁇ L w > 5 dB, preferably ⁇ L w > 7.5 dB (evaluated in accordance with ISO 717-2) is achieved by the decoupling mat according to the invention with a thickness of the mat of 10 mm ,
