Definitions

  • the invention relates to a thermal barrier coating of a foundation of a building.
  • the foundation further includes, in particular, a bottom plate and a moisture protection layer.
  • the thermal barrier coating is arranged at least between a ground and the bottom plate.
  • a cleanliness layer is off DE 198 107 66 known. There is described in particular a method for the production of structural waterproofing against groundwater and soil moisture. On a so-called Erdplanum a lower layer is arranged in the form of a clean layer. On this two mutually perpendicular bituminous sheets and then a protective fleece are applied. Thereafter, a floor slab is made of concrete on the protective fleece.
  • WO 2004/106641 A1 describes a heat-insulating formwork element for producing a formwork of a floor slab.
  • Corresponding elements are, for example, a corner formwork element, edge formwork elements and plate-shaped formwork elements.
  • Some shuttering elements are fixed to each other via dovetailed connections.
  • the plate-shaped formwork elements are superimposed and engage with pyramidal projections into each other. In particular, these plate-shaped formwork elements are arranged offset from one another.
  • the thermal barrier coating is characterized in particular by the fact that it is formed from a plurality of side by side arranged insulating panels.
  • Such foundation or foundation transmits a load of a structure evenly into the ground, ie on the ground.
  • different foundations can be used, which use at least one single, strip or plate foundation, for example in the form of a bottom plate.
  • pressure forces applied from above are distributed over the entire surface of the ground.
  • Such foundations prevent subsidence of the structure by movement in the ground, to avoid cracks in the building. Such cracks could affect the statics of the structure or cause water damage.
  • the foundation is usually also sealed at the same time against oppressive water and protected against groundwater and leachate.
  • the insulation boards according to the invention can be used in a simple manner for producing a corresponding thermal barrier coating and have a sufficiently high compressive strength and resistance to mechanical stress.
  • the use of such insulation boards results in a light, simple and energy-saving production of the thermal barrier coating.
  • the thermal barrier coating is characterized by a high level of thermal insulation.
  • the thermal barrier coating is laid out directly from the plurality of insulating panels on a level subsoil or optionally on an additional layer of cleanliness and / or a film layer.
  • the above-mentioned properties of the insulation board are improved in that adjacent insulation boards abut each other along correspondingly associated plate sides. This is in particular an advantage in connection with a ground-side base plate. When using single or stiffener foundations, only a few insulation boards can be used under this foundation.
  • the thermal barrier coating will be composed of the insulation boards, that at least the mutually associated plate sides have toothing devices.
  • a toothing device can be realized, for example, by corresponding profilings on the sides of the plate, wherein profilings of adjacent plate sides of different insulating plates can be formed complementary to one another.
  • such a toothing device can be formed on each side of a panel insulation board.
  • composition of the insulation boards in this context represents a thermal bridge-free construction, so that the thermal insulation layer produced optimizes the thermal insulation.
  • the corresponding toothing device makes it possible to assemble the insulation boards in any direction in a simple manner, so that unnecessary turning of the boards is not necessary when producing the thermal insulation layer.
  • the insulation board can be seen in the fact that the insulation boards are arranged shock-to-joint in the thermal barrier coating. It is also possible that alternatively or in combination with this installation, the insulation boards from row to row and / or from column to column of the thermal barrier coating are offset from each other. The offset can be determined in this context by the arrangement of the corresponding grooves or springs.
  • the insulation board can be made of a heat-insulating material, in particular lightweight concrete.
  • lightweight concrete has according to German standards a dry bulk density of a maximum of 2000 kg / m 3 .
  • a preferred embodiment for the lightweight concrete is one based on expanded clay. This is characterized in particular by a high porosity and a low weight, so that a force-saving and fast working with such insulation boards is possible.
  • these insulation boards have sufficient inherent strength and sufficient pressure stability for expected surface loads from the concrete slab and the building standing thereon.
  • insulation boards of the corresponding thermal barrier coating on a moisture protection layer, which is formed for example by a corresponding film, which is outsourced before laying the insulation boards on the building surface.
  • the thermal barrier coating according to the invention may already be formed as a capillary refractive layer, which is not capillary sucking or accordingly not hygroscopic, which already results in a good decoupling against soil moisture.
  • the corresponding insulation boards can be laid dry and / or cut. In this way, simply the insulation boards for the production of a solid composite shock-to-joint or offset from row to row and / or column to column can be laid and at the same time can be divided even by staggered arrangement of the insulation boards by cutting to total To obtain a flat thermal barrier coating with desired dimensions.
  • the concrete slab can be concreted on this directly or even with the interposition of a further film, in particular a moisture protection film.
  • the further moisture protection film prevents, for example, that moisture and cement slurry can penetrate into the insulation boards during the production of the base plate.
  • Cutting the insulation boards can be done in this context in a simple manner, for example by means of a stone saw. It is also possible to separate corresponding springs in the region of an outer edge of the thermal barrier coating.
  • this can have at least one cutting marking on its top and / or bottom.
  • insulation boards can be made especially with the use of lightweight concrete with very low primary energy consumption, have a long service life well over the entire period of use of the building and are easily disposable even after completion of the use of the building.
  • the boards are laid dry, not mortared or connected with other materials, see the design above. This also makes it possible that they are recycled, which can be done for example by crushing already used plates. The broken recycled material of the plates can then be used again for the production of corresponding lightweight concrete blocks or insulation boards.
  • the recycled material can also be used as a foundation for road or road construction
  • the invention also relates to a corresponding insulating board according to the preceding description, which is used to construct the corresponding thermal barrier coating.
  • Fig. 1 is a side section through a building 3 with a foundation 2 shown. Of the building 3, only one side wall 21 of the masonry is shown. Below the side wall, the foundation 2 is arranged, the at least one bottom plate 4 and a Thermal insulation layer 1 comprises. Furthermore, 6 moisture protection layers 5 and 23 are arranged between these and also between the thermal barrier coating 1 and a ground.
  • the moisture protection layers 5 and 23 may be formed as films or film webs, which are arranged on the respective layer prior to application of the further layer.
  • the ground 6 can be directly level ground. Furthermore, there is the possibility that a level of cleanliness or even a further moisture protection layer is additionally applied to the leveled soil before the thermal barrier coating 1 according to the invention is arranged.
  • the corresponding moisture protection layers are generally larger in size than the bottom plate 4 and are later connected to a vertical seal 25 or perimeter insulation 24 of the masonry 21, so that the entire construction of the structure 3 has a dry base.
  • Further horizontal seals 22 may be provided directly between the side wall 21 and bottom plate 4 or additionally spaced from the bottom plate 4 in the masonry or in the side wall 21.
  • the thermal barrier coating 1 is also composed of a plurality of insulating panels, see also the following description, these panels are preferably made of lightweight concrete based on expanded clay. Such insulation boards are characterized by a low weight, sufficient inherent strength and pressure stability and by a very good thermal insulation value. Furthermore, such insulation boards are not capillary sucking, that is, from them a capillary-breaking thermal barrier coating can be produced.
  • the laying of the insulation boards is dry, that is, they are not mortared or bonded to other materials.
  • the laying can be done directly on the surface of the ground or on a disposed between the thermal barrier coating 1 and ground moisture protection layer.
  • Fig. 2 An example of a laying is shown, in which four insulation panels have been laid shock-to-joint.
  • the insulation boards all have the same dimensions and edge formations.
  • a toothing device 12 is arranged in the region of the edge of each insulation board, ie along the corresponding plate sides 8, 9, 10 and 11, a toothing device 12 is arranged.
  • This is according to the embodiment Fig. 2 formed as a tongue and groove toothing device 13.
  • Such a tongue and groove toothing device 13 has two springs or grooves along each side of the plate 8, 9, 10 and 11.
  • the arranged in rows and columns 18, 19 insulation boards finally form the entire thermal barrier coating 1 after Fig. 1 ,
  • processing in each direction ie in the direction of the rows 18 or gaps 19, is made possible and at the same time a high resistance to displacement and warping is ensured by the toothing device.
  • Fig. 2 are also the grooves or the springs of the same dimensions and complementary to each other.
  • Fig. 4 Only springs 16, 17 and grooves 14, 15 are arranged in each case. These engage in each other in juxtaposed and shock-to-joint insulation boards 7, see again Fig. 2 ,
  • Fig. 3 is a further embodiment of a laying of insulation boards 7 shown. These are from row to row, see reference numeral 18, offset from each other, wherein the offset corresponds approximately to half a length of a corresponding insulating board. This staggered arrangement is possible due to the tongue and groove toothing device 13 and the engagement of corresponding grooves 14, 15 and springs 16, 17. It would also be a staggered arrangement in the direction of the columns 19 possible, see Fig. 2 ,
  • grooves or springs along each side of the plate can be arranged, or that these grooves or springs along a plate side or on different sides of the plate have different dimensions and shapes.
  • Fig. 3 is still recognizable that 1 smaller insulation boards or parts of insulation boards 7 are used to complete the corresponding thermal barrier coating.
  • These parts of insulation boards 7 can be made by cutting an original insulation board, for example by means of a stone saw. There is also the possibility to separate over the edge of the thermal barrier coating 1 protruding springs.
  • Such a halved insulation board is arranged in every second row 18 as the first insulation board laying.
  • Fig. 1 will be after one Fig. 2 or 3 produced thermal barrier coating 1 additionally applied a moisture protection layer 5. Then then the bottom plate can be concreted. By this moisture protection layer 5 is avoided that moisture and cement slurry from the concrete slab penetrate into the insulation boards 7.
  • Fig. 4 is a plan view of an insulation board 7 is shown. Along the in Fig. 4 upper plate side 8, two springs 16, 17 are shown. Such springs 16, 17 are also on the in Fig. 4 Left side plate 10 shown arranged. On the other sides of the plate 9 and 11 grooves 14, 15 are provided analogously. Furthermore, in Fig. 4 for example, a cutting marking 20 arranged on an upper side of the corresponding insulating panel 7. This can serve as an aid for halving an insulation board, for example by means of a stone saw.
  • the insulation boards according to the invention or the thermal barrier coating made of them meets all the requirements that can be placed on a modern building.
  • the insulating panels are characterized by a sufficiently high compressive strength and a high resistance to mechanical stress. Furthermore, they ensure high thermal insulation with a thermal resistance of not more than 2.50 m 2 K / w.
  • the arrangement of the thermal barrier layer also results in a thermal bridge-free construction of the foundation. Due to the material of the insulation boards a hygroscopic decoupling against soil moisture is achieved and at the same time a rotting resistance and security against pests. Furthermore, a light, simple and energy-saving processing for the preparation of the thermal barrier coating 1 is possible.
  • the thermal barrier coating according to the invention has advantages.
  • the corresponding insulation boards are produced without chemical additives or hazardous substances. All aggregates are of natural origin and standardized, so that the use of appropriate insulation boards from an environmental point of view is completely harmless.
  • the primary energy required to produce the insulation boards is very low and they have a long life, which goes well beyond the entire useful life of the building.
  • the recycling can take place for example by crushing the insulation boards, after which then the broken recycled material for the production of lightweight concrete blocks, insulation boards or the like can be used, or can be used as a foundation for road and road construction.
