Definitions

  • the invention relates to a floor structure, on the one hand has a high thermal insulation and on the other hand has a good sound insulation, wherein the sound insulation is formed against structure-borne noise as well as against airborne sound.
  • the object of the invention is to provide a floor structure that can be created with little tools, can be produced quickly and with the least possible use of personnel.
  • From the DE 19 50 367 A is a method for applying floor coverings with a sound- and heat-insulating underlayer known in which one attaches a layer of foamable plastic material and this foams and hardens.
  • a solid, pressure-distributing, plate-shaped auxiliary layer is used.
  • the aim is to provide a floor structure that allows compensation of existing irregularities and also the laying of pipes of all kinds, which has a high thermal insulation with a heat conduction less than or equal to 0.08 W / mK, in particular a heat conduction of about 0.04 W / mK or better, which provides a good insulation against structure-borne noise and finally provides an insulation against airborne sound in the order of about 32 dB, preferably 34 dB.
  • a floor structure with thermal insulation and sound insulation which has the following layers in the order specified from the bottom to the top: 1. A lowermost layer of particles having a thermal conductivity ⁇ ⁇ 0.1 W / mK, this Layer has no binder. 2. A middle layer of mats made of plastic foam and at least 1 cm thick. 3. a plastic film and 4. a stable, floating screed layer, the screed layer being surrounded by a circumferential edge insulation.
  • This floor construction has a lot of advantages. Except for the screed layer is a drying system, it requires no drying time or curing time. Apart from the screed layer, there are no restrictions with regard to the application of the layers, neither by temperature nor by other weather conditions.
  • the layers below the screed layer can be applied very quickly and efficiently, it is easily possible that a single worker per hour 20 sqm substructure, without the screed layer created.
  • the investment costs are low, the material can be transported by simple means, such as a small truck to the site, the volumes are manageable.
  • the manufacturing company does not need special machines or tools.
  • the application of the layers below the screed can be done with simple manpower. For the client there are enormous cost advantages.
  • the screed layer can be applied without having to wait. Overall, it is a thermally and acoustically excellent insulating system that is inexpensive to produce.
  • the lowermost layer has a grain size of 0.01 to 10 mm, preferably 0.01 to 1 mm.
  • the particles are preferably very small, the material is present as a flour, while 80% of the material has a grain size below 0.8 mm.
  • the particles consist in particular of soft foam.
  • the lowermost layer has a thickness of 3 to 5 cm. The particles are obtained by crushing old foam, in particular of developed insulating layers of old equipment.
  • the mats are preferably made of soft foam material. In particular, they have a density of 50 to 150 kg / m 3 , preferably 80 to 125 kg / m 3 .
  • the middle layer is composed of the mats such that there are no joints between adjacent mats that extend to the lowest layer. In particular, the middle layer has a thickness of 1 to 2.5 cm.
  • the mats are elastic, they are made of soft foam.
  • the film is bonded to a felt layer.
  • This felt layer reinforces the film and protects it. It avoids damage to the film by sharp parts.
  • the felt layer is below.
  • edge insulation is an intact and sufficiently thick edge insulation.
  • a flexible band of foam with a thickness of at least 5 mm, preferably at least 10 mm is used.
  • the edge insulation is applied to the walls before the application of the lowest layer. It then lies at the edge below the lowest layer. It is at least a few millimeters, preferably several centimeters, above the screed before. It is preferably folded later on the surface of the screed layer and cut.
  • a skirting board should have no mechanical contact with the screed layer, but rather by the edge insulation be separated from this.
  • the edge insulation consists of the same material as the mats.
  • FIG. 1 is denoted by 20 a supporting concrete ceiling, on it is a wall 22.
  • a lowermost layer 24 is applied, which is made in the embodiment of PUR (polyurethane) particles.
  • Foam material in particular recycled foam material, is used, the particle size being in the range from 0.01 mm to 10 mm, preferably 0.01 to 1 mm.
  • the lowest layer can be carried out as well as in the above DE 199 37 314 A1 is described for the local insulating layer.
  • PUR particles instead of PUR particles, it is also possible to use small particles in the same particle size range of soft PUR foam, polyether, latex, textiles or other materials, provided that the thermal conductivity lambda lies in the range below 0.1 W / mK. With the rigid foam particles made of PUR, a thermal conductivity of about 0.04 W / mK can be achieved.
  • supply lines 26 of all kinds can be embedded or on the concrete ceiling 20 resting supply lines 26 are covered by her.
  • the supply lines 26 include, for example, electrical Pipes, water pipes, gas pipes, sewers and the like.
  • the lowest layer 24 is chosen so thick that the supply lines 26 are sufficiently covered, for example, at least 2 cm are covered.
  • the lowermost layer 24 is leveled. It is introduced without any binder. Later, no binder is added. It is possible to moisten the particles slightly. This can be done before, during application or after application to the concrete ceiling 20. Thus, the lowermost layer 24 can be compacted more easily, it can avoid electrostatic charges and the spreading and leveling is simplified.
  • a layer 44 is applied as the middle layer 28, which is composed of mats 30.
  • These are in turn made of a foam material, in particular plastic foam material. It can here original plastic foams or plastic foams are used, which are made of recycled foam grains and polyurethane binders.
  • This middle layer 28 is composed of individual mats 30, which are supplied, for example, as rolls or blanks, in particular rectangular blanks, and are placed directly on the lowermost layer 24.
  • the individual mats 30 are 1 to 2.5 cm thick. They consist in the embodiment of elastic latex foam, but it is also possible PUR foam or polyether foam.
  • the mats 30 are used with a density of 50 to 150 kg / m 3 .
  • the PU foam mats and the polyether foam mats have a density of about 80 kg / m 3
  • latex foams have a density of their mats of 120 to 125 kg / m 3 .
  • the mats 30 are laid so that between the individual mats 30 no gaps remain free, which go through to the bottom layer 24.
  • the mats 30 are thereby laid so that either adjacent mats overlap each other or adjacent mats are installed butt to joint and the occurring joint are covered by narrow strips of the mats 30.
  • the mats 30 have constant thickness. Due to the leveling of the bottom layer 24 and the individual mats 30 are horizontal. Only at the overlap areas or at the joints bridging strip is a bit higher level. this shows FIG. 1 It shows that the surface of the middle layer 28 has smaller steps.
  • a waterproof film 32 is placed on the middle layer 28 . It consists in the embodiment of PVC. Its task is to produce a waterproof layer. It is made from a coherent, large film web. When made from roll stock, the individual sheets overlap at least 10 cm and / or are preferably glued together, welded or otherwise bonded.
  • the film 32 is covered with a felt layer 34.
  • the film may then have a somewhat smaller thickness, for example 20 to 25 micrometers, in particular 37 micrometers, the felt layer 34 has a density of 150 to 750 g / m 2, in particular 200 g / m 2.
  • a screed layer 36 is applied as the uppermost layer 44.
  • a commercial, already known from the prior art screed layer is used, it is preferably reinforced. It is possible to use screed machines and all other aids that are already known for creating load-bearing, floating screed layers.
  • the substructure below the screed layer 36 has a thermal conductivity of less than 0.1 W / mK, in particular in the range of 0.04 W / mK. It provides a very good and even excellent insulation against structure-borne noise and also against airborne sound. After application of the screed layer 36, the total thickness of the underlying layers 24 to 28 reduced by about 3 to 20%.
  • a peripheral insulation 38 is made of a flexible tape.
  • This edge insulation 38 together with the layers 24 and 28 forms a trough. Any mechanical contact of the screed layer 36 with the wall 22 and also the concrete ceiling 20 is excluded. There should also be no material hardening, thickening or particles, such as stone chips, einfinden that could make contact between the screed layer 36 and 22 in front of a wall.
  • the edge insulation 38 is treated in connection with the layers 24 and 28 like an electrical insulation. It is to be achieved that the edge insulation 38 has a uniform soft structure everywhere and is completely intact all around.
  • edge insulation 38 As a favorable edge insulation 38, the training after the above DE 34 09 535 C2 or strips made of the material of the mats 30 described above, preferably having a density of 120 to 180 kg / m 3 .
  • the edge insulation 38 is present as a rolled product.
  • the edge insulation 38 surrounds at least the screed layer 36, advantageously also the film 32 and the middle layer 28.
  • the edge insulation 38 is placed on the bottom layer 24 before the middle layer 28 is applied.
  • the edge insulation 38 extends several centimeters, preferably at least 3 cm, in particular at least 10 cm, in the horizontal and is then angled near the wall 22 upwards. It always extends beyond the level of screed layer 36 upwards, this at least 2 cm. It also works with overhang, so more material than required. The supernatant is cut off only when the further work is largely, in particular completely completed. So show the Figures 1 and 2 a wear layer 40, for example a wear layer 40 in the form of a carpet or a parquet on the screed layer 36.
  • this wear layer 40 is not in contact with the wall 22, but separated by the edge insulation 38 thereof.
  • the edge insulation 38 is folded over the wear layer 40 on this and extends over at least 5 mm, preferably 10 mm parallel to this.
  • a skirting board 42 is located above the edge insulation 38. It is separated from the wear layer 40 by the edge insulation 38. The skirting board 42 is connected to the wall 22.
  • the edge insulation 38 is U-shaped. On the outside, the upper, cut end of the edge insulation 38 is covered and protected by a layer 44 of permanently elastic putty. This elastic putty is chosen so that it does not form a sound bridge. He should as possible have the same acoustic properties as the edge insulation 38.
  • the materials used for the substructure have a high dynamic stiffness value and provide good sound insulation. This sound isolation is both in the vertical direction, ie with respect to the supporting concrete floor 20, as well as in the horizontal direction, ie opposite walls 22nd
  • the thickness of the bottom layer 24 is 5 cm
  • the thickness of the middle layer 28 is 2.5 cm
  • the film 32 has a thickness of 0.2 cm, including a felt layer 34, so that the total thickness is 7.7 cm , which shrinks after application of the screed layer 36 to about 7 cm.
  • the bottom layer 24 has a thickness of 3 cm
  • the middle layer 28 has a thickness of 1 cm and again a film 32 provided with a felt layer 34 and having a thickness of 0.2 cm is used. This results in a total thickness of 4.5 cm. This reduces after application of the screed layer 36 to about 3.5 cm.
  • a sound insulation of about 34 dB is achieved in the embodiment according to FIG. 2 a sound insulation of about 32 dB.
  • edge insulation 38 In making the edge insulation 38, a tape of the same material as used for the mats 30 is adhered to the wall of the wall 22. It is positioned so that the upper edge is at least 10 cm above the height of the load-bearing concrete ceiling 20. This upper area, above the height of the finished substructure, will not be glued. Below, the edge insulation 38 is turned horizontally and located on the lowest layer 24. There it extends about 10 cm in the horizontal. In this way, one achieves the advantage that the lowest layer 24 can extend directly to the wall 22 and after completion a kind of barrier along the walls 22 is formed so that no components of the bottom layer 24, in particular not the finer component of the particles is moved vertically along the wall 22, when performing the subsequent work, in particular the screed layer 36 applies. You can also work so that the edge insulation 38 is not connected to the wall 22 at all, but is only temporarily fixed. The temporary fixation can be removed once the floor has been built up. You can also use a pressure-sensitive adhesive.
