Definitions

• the present invention relates to a wall construction, as already described in EP08874021.2 for the construction of houses and buildings.
• This wall construction has a symmetrical structure of pressure-stable plates that are kept at a certain distance.
• the two plates absorb the pressure forces and consist of particularly pressure-stable material such as natural stone, artificial stone of all kinds, concrete and other earthenware, as well as ceramics up to substances containing glass or glass - hereinafter called earthenware - which are pressure-stable, but usually also by a brittle and fragile structure are marked.
• Natural stones such as granite, granite-like stones such as gneiss, as well as marble, limestone, high-pressure-resistant modern ceramics, glass ceramics or glass should be mentioned, as well as all other materials made of stone or ceramics and naturally or artificially created earthenware.
• the two plates can each consist of the same material or of different materials, for example the outer stoneware disk made of natural stone and the inner stoneware disk made of concrete.
• these materials are characterized by high resilience under compressive loads with a comparatively low specific weight, but such materials are also relatively unstable when subjected to tensile and bending loads, especially if they are to be kept as thin as possible and are material-saving and, in particular, as light as possible should be interpreted.
• these slabs are provided with a stable reinforcement and, for example, with the help of Fiber materials made tensile stable. Coatings with the help of fibers that are as stable as possible and binders or resins that are as temperature-stable as possible serve to coat the fiber with the stone surface.
• the main goal in this invention is to bind as much carbon as possible in the insulation material, which can additionally stiffen the overall construction in order to make the building material as CCV negative as possible.
• an insulation material based on biochar or artificially produced coal is used.
• Biochar is the solid that is formed during the pyrolysis of biomass and is characterized by its highly porous structure and a carbon content of over 50%. All biomass such as wood, crop residues, greenery from roads, solid digestate from biogas plants or sewage sludge can be used as the starting material for the biochar to be used in the insulation material.
• artificially generated coal can also be used for the insulation layer, which is obtained directly from CO2 using electrical or electromagnetic energy and / or electrolytic processes. Although these methods are more energy-intensive, they are also interesting in countries with a high renewable electricity mix.
• the coal serves the purpose of good thermal insulation, reduces the weight of the insulation layer and ensures permanent storage of carbon in the system.
• the coal is introduced, for example, with a binder or a proppant into the space between the pressure-stable plates, so that the plates are firmly bonded to one another through the insulation layer.
• a binder or a proppant into the space between the pressure-stable plates, so that the plates are firmly bonded to one another through the insulation layer.
• Other fillers to improve the physical properties such as tensile strength, heat conduction, radiation, etc. are advantageous.
• Loose fillings of coal-based materials can also be used if the two stone slabs are each designed to be self-supporting so that firm gluing can be dispensed with.
• the present invention proposes a way of additionally strengthening such thinly designed stone or earthenware plates or ceramic or artificial stone plates, which are stabilized sustainably in an inexpensive manner and become self-supporting wall elements in the way proposed here, as an effective carbon sink.
• the stone, the ceramic or the glass and other pressure-stable materials such as thin concrete slabs - generally shown here as the earthenware - which previously meant additional weight for the construction of buildings purely as facade cladding, are now themselves the load-bearing element of the house wall and the coal-based insulation layer together with preferably carbon fibers, if they are made from organic oil, for an efficient carbon sink.
• the invention proposes such a route with a symmetrical wall structure, the characteristic of the flatness of the stone slab becoming a further essential core of the invention in wide temperature and pressure ranges, in combination with a third characteristic feature of the use of the facade element itself as a supporting part, which is carried out with the aid of a tensile fiber layer, which is preferably made from vegetable-based carbon or, alternatively, consists of low-energy fibers such as glass fibers or stone fibers.
• the path ensures that the earthenware is stabilized under a wide variety of thermally induced mechanical loads, as well as purely mechanical loads, in such a way that it is stabilized against mechanical destruction by tearing the wall plate on the one hand, and suitable for the respective application and load cases in particular also be additionally protected against thermal bending.
• the dimensional stability when there is a temperature difference on the inside and outside of the wall and also the associated temperature changes on the weather-dependent side is also of significant importance, which can also be supported by the fact that the plates each consist of different materials with different expansion coefficients.
• the essence of the solution to find the most suitable insulation material for such self-supporting walls in sandwich construction is to keep the overall expansion coefficient of the inner and outer panel as small and in particular as possible as possible, to allow the absorption of carbon, to ensure good fire protection behavior and one have a high insulation value, as well as being dimensionally stable, waterproof and frost-proof.
• promising candidates are, above all, biochar-based building materials, which have sufficient flexibility and sufficient tensile strength to prevent them from buckling by gluing with the fiber-stabilized earthenware plates.
• the invention filed for registration relates to the construction sector, in particular to building construction, more precisely house construction with service buildings, apartment buildings, pavilions, halls and any type of building in general.
• the core of the invention relates to a technology for creating a house wall as a building element, with the functions of static load transfer and the facade with all functions of a building envelope and the corresponding physical requirements in accordance with the current standards, which are now to be upgraded via the insulating materials to the carbon sink.
• the wall elements are prefabricated and finished on site.
• the ceiling constructions are placed on the wall elements.
• the wall elements combine all structural and structural requirements in a sandwich structure.
• the outer thin disks made of earthenware or other pressure-stable materials mainly take over the normal forces (disk forces). They can be used directly as finished surfaces, both inside and outside.
• the core of the sandwich is a coal-based, preferably shear-resistant, heat-insulating material that either connects the adjacent panes or only fulfills the insulation properties if the two panes are self-supporting without a shear-resistant connection. In the case of a rigid connection, the shear forces become with the core absorbed from bending stresses, there is sufficient bending rigidity across the element.
• the element is thus secured against kinking and loads such as wind loads occurring horizontally across the element can be absorbed.
• the load transfer and load transfer design from the floor slabs to this sandwich element brings the vertical loads symmetrically to the panes without creating a physically intolerable thermal bridge.
• the watertightness, vapor tightness is guaranteed by the interaction of the sandwich materials with special connection details.
• the elements are installed as pendulum supports in the ceilings above and below.
• the thermal insulation values can reach the Swiss Minergie standard.
• the thin panes are made of a pressure and shear resistant, waterproof material such as concrete, natural stone, glass, ceramics. They are secured with reinforcements against tensile stresses from thermally asymmetrical deformations and against tensile stresses in the area of the stress distribution in the load introduction zones, which could lead to unannounced total brittle fractures. Likewise, imperfections in the material and in the construction can be bridged and a good-natured, as ductile material behavior is generated.
• the sandwich core consists of a shear-resistant, highly heat-insulating structure, usually made of a sufficiently firm foam or other binding agents with biochar or artificially produced coal.
• the load transfer consists of a thermally weakly conductive, pressure and shear resistant element made of GRP or wood or a Half-timbered or made of carbon-containing mineral material.
• connection between the washers and the load application, the washers and if necessary. the insulation core is also produced using permanent shear-resistant bonds.
• Commercially available bonds are used, either based on resin or mineral glue such as high-temperature water glasses with a temperature resistance of at least 500 ° C.
• fiber materials with a matrix are proposed for the stabilization of the stone slabs themselves.
• carbon fibers are used here, which were preferably produced from biomass or directly from C0 2 .
• Stone fibers and natural fiber materials that stabilize the stone over a large area and prevent it from expanding and breaking can also be used.
• the natural stone itself has a very low expansion module, which can be adjusted with the fiber stabilization, because natural stone is compressible due to its porous structure. In the event that the fiber draw becomes correspondingly large and the correct fiber is used, or with the help of the fiber an appropriate pretension can be brought into the composite of fiber matrix and stone, a temperature-related expansion of the stone slab is minimized.
• the carrier material hereinafter referred to as carrier, consists - as described, for example, in patent application EP 106 20 92 - of a fiber-reinforced matrix, which is a synthetic resin or possibly a ceramic material itself. It comes e.g. Carbon fibers are used that withstand high tensile loads and contract under the influence of heat, i.e. have a negative coefficient of thermal expansion and sustainably stabilize a more or less thin stone slab even under changing temperature loads. As a result, the plate is particularly protected against cracks due to overexpansion, and the breakage caused by mechanical stress is counteracted vertically on the stoneware.
• thermostable epoxy resins polyester resins, resins based on phenol, polyimide, cyanate ester, melamine, polyurethane, silicone or silicate or water glass, called matrix, in combination with z.
• polyester resins resins based on phenol, polyimide, cyanate ester, melamine, polyurethane, silicone or silicate or water glass, called matrix, in combination with z.
• Carbon fibers which have a negative coefficient of thermal expansion, enable such secure stabilization even of very large stone slabs, which have the height of an entire floor.
• the requirement is met to optimize the mechanical strength and temperature resistance of thin stone structures in such a way that the overall expansion coefficient of the slab is controlled over a wide range of temperatures in order to avoid bowl-filling of the entire slab and still achieve a lightweight construction.
• the invention describes a suitable solution with the help of trusses made of GRP parts or solid material, for example made of biochar-based materials, which on the one hand has a high pressure resistance and on the other hand if possible must have insulating properties in order to effectively transfer the force into the fiber-reinforced stone slabs on the one hand and still avoid thermal bridges in order not to allow any condensation and therefore mold to form.
• the overall construction of the novel wall construction described here takes into account the fact that the necessary vapor barrier is built in through the fiber matrix. Both the stone slabs and the coal-based materials of the insulation layer can absorb and release water and thus have a regulating effect on the moisture balance in the interior.
• the stone slabs have the same effect and can thus become a cooling surface in summer when the moisture stored in the stone and insulation material evaporates. If suitable granite is used, then such house walls are absolutely frost-proof and corrosion-free and practically do not age, especially if they are polished on the outside. Because of the high Adsorption capacity of the biochar in the insulation layer prevents condensation water from escaping, preventing any mold growth.
• this carbon not only causes the insulation properties and moisture regulation to be improved, the coefficient of expansion and the weight of the insulation layer to be reduced, but the components are also affected by the high Volume of the insulation layer to an efficient carbon sink in order to enable the climate targets to be achieved through a building material adapted to the climate problem. While the construction with previous building materials caused CO2 emissions, this new building method uses C0 2 negative materials. The building material stores or sequestrates more carbon in the material than was used to manufacture it.
• biochar-based cement or geopolymer mortars biochar-based resins or foams made of PU, glass or mineral foams are used, which, with the help of fiber reinforcement of the outer stone panes, become a self-supporting wall and facade element that is capable of more carbon to save than when it is produced in the form of C0 2 and escapes into the atmosphere.
• Fiber-stabilized stone slices with an insulating layer made of foam material in the middle layer are constructed symmetrically and dimensioned so that they can take loads and buckling forces with a comparatively very low weight. For this reason, the insulation material may have to have a high carbon content. have sufficient tension stabilization.
• the carbon can otherwise loose insulation materials made of glass wool or rock wool are added if the two stoneware disks are self-supporting, which can be achieved by the fact that the respective disk itself consists of two stone layers with a middle layer made of fiber matrix.
• FIG. 1 The picture shows two stone slabs (1) stabilized with a carbon layer (2).
• An insulation layer (3) is attached between the fiber-coated stone slabs and has a high carbon content.
• the insulation layer (3) is sufficiently stable to prevent the panels from buckling outwards.
• the sufficiently tensile insulation layer (3) can be made over the entire surface or, as shown in Figure 2 in cross-section, only over part of the surface, meaningfully so that the stone slabs are prevented from buckling in the central region. Both figures also show the load introductions (4) above and below.
• Fig. 3 shows that the fiber-coated stone slabs are made in such a way that each of the slabs is made of two stone slabs with an internal carbon layer. In the middle there is an insulation layer (3) with a high carbon content. The insulation layer (3) is loosely inserted or attached between the stone slabs and has no stiffening function.
