    The invention relates to a wall for a building, the wall having a plurality of layers with at least one layer of wood and at least one support layer of substantially inorganic material. Multi-layer walls having at least one wood layer and a carrier layer of inorganic material are generally known. In this case, wood panels, shingles or slats are applied, for example, to improve the visual appearance on brick walls or reinforced concrete walls. However, the wood layer often only has an optical significance. Under walls here include all wall-shaped components that can be arranged vertically, horizontally or obliquely. These walls also include floor panels and ceilings or roof tiles.
    The inorganic support layer is in the simplest case a brick wall, which brick wall may also be filled or traversed with organic material. Likewise, the support layer made of concrete, or reinforced concrete as well as only consist of metallic base material. The carrier layer can also be a stone wall, or a clay wall, as well as mixtures thereof, as is often the case with old buildings.
    From DE 20 2005 019 680 Ul a log cabin with a brick wall and a wooden wall is known. Brick wall and wooden wall are connected by beams. However, the brick wall is unfavorably arranged outside the wooden wall to protect the wooden wall from the weather. On the one hand, this is not visually appealing, as the brick wall must at least be plastered; on the other hand, the thermal conductivity of the brick wall is higher than the conductivity of the wooden wall. As a result, the temperature is relatively low on the inside of the brick wall, which may fall below the dew point. This leads to mold, rot and similar undesirable phenomena. In addition, the heat capacity of the carrier layer is not used because it is behind the wooden wall.
    Object of the present invention is to overcome these disadvantages and to provide a wall or a method for producing a wall, on the one hand allows good thermal insulation, while having an increased heat capacity and which additionally allows heat exchange.
    This is inventively fulfilled in that between the carrier layer and the wood layer, a connecting layer is arranged and the connecting layer contains lines for heat exchange.
    By attaching cables that can heat and / or cool the space indirectly via the carrier layer, the room climate is further improved. In addition, can be completely or partially dispensed with conventional radiant heater in the interior of the building through this construction, creating more free wall surfaces arise. As a result, the living space can be better used. In addition, a particularly environmentally friendly design is chosen by the use of wood as an insulator, since so no biologically hardly degradable plastic materials must be used for insulation. At the same time, wood not only has good insulating properties, but is visually more appealing than conventional insulating materials such as insulating wool. It can improve the look both in the interior as a decorative wall cladding, but also externally attached to enhance the appearance of the building.
    In addition, this solution is not only suitable for the construction of a new wall, but also for the renovation of existing walls.
    When the room is heated at low outside temperatures through the lines described, the temperature increase in the area between the wood layer and the carrier layer also minimizes the risk of the temperature falling below the dew point. In addition, the carrier layer is dried. This minimizes the risk of mold growth or similar undesirable changes.
    The wood layer can, but does not have to have a static supporting function. Depending on the embodiment of the layers and depending on the requirements of the specific case, the wood layer can also act only statically supporting or have no static function.
    By placing a heat-insulating wood layer on the outside of the carrier layer, the advantages of both materials are optimally utilized. The im
    Generally low thermal insulation of the carrier layer is of little importance due to the good insulating properties of the wood layer. Due to the strong insulation of the wood layer, the temperature difference at the inner and outer side of the carrier layer is reduced at the same time, and thereby the heat capacity of this is ideally used.
    In addition, this optimizes the moisture management, since the moisture absorption and moisture-releasing capacity of the carrier layer is increased, which has a positive effect on the indoor climate of the building.
    It is particularly advantageous if the lines extend over the majority of a longitudinal section of the wall. This optimizes the heat exchange efficiency. There are various forms of laying the lines conceivable. So classic meander shapes can be used, as well as round or angular spiral shapes. It is also possible to change the intensity of the line assembly in areas that are particularly important for thermal reasons, such as corners or window frames. For example, the lines can be particularly tightly led around attic shafts, window and door frames. It is also possible to adjust the cross section of the pipes in certain places in order to optimize the efficiency. For example, flattened lines can be used to increase the effective surface area.
    It is particularly advantageous to allow the heat exchange through a hydraulic system. By connecting the lines with a hydraulic heating or. Cooling device is found an energy-efficient and cost-effective solution for heating or cooling of the interior.
    This can be dispensed with expensive heating technology on the inside of the wall to the interior. The inner wall surface then replaces space-consuming and expensive radiators or other equipment and serves as heating and cooling surfaces. The heating and cooling by radiation and natural convection is also more compatible and more pleasant for the human body than air heating and air movement.
    In the connection layer, in addition to the lines for heat exchange and electrical cables and water pipes can be laid. The arrangement of ventilation pipes and installations of all kinds are possible in the connection layer. Again, dowels can serve as fasteners.
    This is particularly advantageous for renovations because it allows new home technology to be installed without disturbing residents. These can even be left in the building during refurbishment. Furthermore, it is possible that public buildings such as schools, hospitals, or homes and offices during normal operation, the home technology to modernize or renovate or in the described form.
    In order to ensure a regular spacing of the wood layer from the carrier layer, it may be advantageous to provide spacer elements which always keep the distance between the carrier layer and the wood layer the same. These spacers can either be attached only to support layer or layer of wood and only rest on the other. But you can also be permanently connected to both.
    These spacers may conveniently serve as a mounting option for the lines in the connection layer.
    As an advantageous embodiment, it is possible to highlight the possibility of designing the spacer elements as dowels. This saves on potentially toxic or environmentally harmful adhesives or rust-prone screws. Particularly advantageous is the use of wooden dowels, as a particularly sustainable design is possible. Dowels made of wood have similar thermal conductivities compared to the wood layer and therefore do not form a cold bridge, unlike screws. It is preferred but also the use of wood screws possible, which also offer the advantage of Einstofflichkeit.
    If spacer elements are used, then it makes sense to arrange the lines around the spacer element, in order to keep as small a surface loss of the lines as possible by the spacer elements and, on the other hand, to prevent damage to the lines by the spacer elements.
    In order to increase the efficiency of the heat exchange, it is advantageous that at least a part of the connecting layer is designed as a cast layer with preferably good thermal conductivity. This allows the lines with the
    Carrier layer and / or the wood layer are at least partially thermally coupled and the heat flow can be optimized. At the same time, the formation of condensation directly on the pipes can be prevented, which further reduces the risk of microbial attack such as mold growth. Furthermore, this arrangement provides increased stability of the entire wall construction. The material for casting can be chosen differently. For example, cast concrete is particularly suitable for this, but many other materials such as plastics or mineral substances such as gypsum are also conceivable.
    Sometimes it is beneficial to protect at least parts of the outermost areas of the wall from the weather by an additional layer. Therefore, it may be desirable to provide a facade layer. Depending on the type of building or weather conditions, this façade can only be used on parts of the wall, for example on areas near the floor, in order to preserve the wood look in certain other areas. It can also assume static functions, such as the stabilization of the insulation.
    The facade layer can in principle consist of all conventional or suitable facade structures. Thus, it can be, for example, plaster on a plaster base, wood formwork of all kinds, plastic, stone, glass or other materials, applied directly or with the aid of suitable support systems to the wall construction. A rear ventilation can also be provided. Particularly advantageous is the attachment of sound insulation elements, for example wood concrete. In principle, prefabricated modules can be used, which are easily and quickly applied, if necessary, after adaptation on site, on the wall construction, whereby a particularly cost-effective, fast and easy construction is possible.
    Since the optimum insulation is of great importance, it may be advantageous to provide a further insulating layer. This can for example be directly under a facade layer, but also be arranged in other places. For stability reasons, it may be advantageous to install support elements in the insulating layer. These can be independently attached to the respective adjacent layers, such as nailed, screwed or resting on the dowels penetrating into the insulating layer. For the design of support elements of this type different materials such as wood or plastic are conceivable.
    In addition to their supporting function, they can also serve as spacers or as anti-sag for the insulation material. For this purpose, it is particularly advantageous if they are designed as particularly preferably substantially horizontally extending squared timbers, or beams.
    In order to increase the stability of the wall, it is advantageous to provide connecting elements which connect the wood layer and the carrier layer to one another. Especially in combination with spacer elements and / or a cast layer, this can lead to a high strength of the wall construction.
    It is particularly favorable when the wood layer has at least one prefabricated laminated wood element, with at least three interconnected layers of directly adjacent board or post-like woods, of which at least two adjacent layers each have different directions, the layers being respectively connected by dowels, which pass through the layers of woods substantially normal, wherein at least one inner layer is formed by posts. Due to the nature of this plywood element, which ideally consists only of wood and forms a relatively thick layer of wood, the fire safety can be increased. In the case of a fire, such laminated wood elements behave like solid wood elements, i. they are characterized by a high fire resistance. In addition, the installation is simplified by standardized elements.
    Other known advantages of such laminated wood elements can bring additional benefits by their use. Thus, the high sound and heat insulation due to such panels as well as the excellent building physics properties bring about a further improvement.
    By appropriate circuit of the lines heat exchange circuits can be formed, which can be switched on and off independently of each other. Thus, for example, individual walls, or even individual interiors can be heated or cooled and so unnecessary energy consumption can be prevented.
    From the perspective of environmental protection and recycling, it is beneficial if the plywood element is unimposing. It also prevents the formation of toxic gases in the event of fire.
    In order to facilitate the assembly of the laminated wood elements, it is favorable if the laminated wood element has at least one connecting edge and is thereby connectable to at least one adjacent laminated wood element, preferably with a groove / tongue, or via leafing, dovetail and / or screws. As a result, the plywood elements can be made more handy and smaller, as well as lighter, and by simply and securely connecting along the connecting edge, the entire carrier layer can nevertheless be covered on the building.
    In order to achieve a good insulating effect by the wood layer alone, it is advantageous if the thickness of the layers of the laminated wood element increases from the outside in and the thicknesses of the layers are preferably between about 8 mm and 120 mm.
    However, it should be emphasized that the wood layer can also be constructed differently and the described embodiment with laminated wood elements merely represents a preferred variant. For example, it can also be screwed, finger-jointed or nailed wall elements, glued cross-laminated board or even wood layers, some of which have been treated or enriched with other building materials. For example, wood layers with textile or molasses inserts would be conceivable.
    The invention also relates to a method for producing a building shell with a plurality of layers, in which initially a carrier layer of essentially inorganic material is produced, after which a layer of wood is applied thereto.
    The stated object is also fulfilled by the fact that the wood layer is applied to the carrier layer and that before and / or after the application of the wood layer lines are arranged on the support layer and / or on the wood layer. This can be prevented in the ideal case falling below the dew point and thus the condensation of the water inside the wall construction. The support layer, or an existing brick wall of the building can be easily extended for renovation work to these lines and the wood layer, without major encroachments destructive nature would be necessary. Thus, even on existing old masonry can be subsequently applied very easily, inexpensively and quickly an environmentally friendly insulation. For new buildings, the effect is all the greater, since the support layer can already be aligned during construction so that the wood layer and the lines are connected to it in a further step. Due to the prefabricated wood layer, the installation is particularly fast and cheap. It may be advantageous to apply the lines to the wood layer before the wood layer is applied to the carrier layer. Thereby, the connecting step of the wood and carrier layer is further simplified and can be performed faster. It may be beneficial to protect the lines on the wood layer with a protective layer to prevent damage. This is especially true when the step of applying the leads and the step of applying the wood layer to the backing layer are at different locations and / or not directly one behind the other.
    Particularly simple, fast and inexpensive, this step for connecting the wood layer can be carried out with the support layer, if prior to attaching the wood layer on the support layer, the wood layer is equipped with spacers with a small cross-sectional area. By means of these spacer elements, no consideration has to be given to a predetermined distance between the wood layer and the carrier layer by the person skilled in the art of assembly. The orientation of the wood layer is unnecessary by the spacer elements.
    In order to facilitate and improve the heat exchange from the lines to an environment outside the wall, it is favorable if, at least partially, a casting layer, preferably a thermally conductive layer, is poured into a cavity between the wood layer, spacer elements and carrier layer.
    In order to further support the insulating effect of the wood layer, and to save material costs, it is favorable if before and / or after application of the wood layer, a further insulating layer is preferably applied to the wood layer by the use of inexpensive biodegradable insulating materials.
    In order to improve the optical effect of the building, it is advantageous if, before and / or after the application of the wood layer, a facade layer is applied to an outside of the wood layer, preferably to the further insulating layer. This also makes it possible for the building owner, regardless of the structure of the wall and regardless of the procedure, to choose freely when designing the appearance of the building. Furthermore, the wall construction is even better protected against the weather. It is advantageous if already pre-cut elements are delivered to the site and only the installation must be done. It is also possible to tailor these elements locally, or to adapt details of prefabricated elements directly to the construction site. As a result, expensive construction site hours can be avoided. It is advantageous if the wood layer with protruding dowels and fasteners as well as attached to the wood layer, or to the dowels or spacers lines are factory prefabricated and then brought to the site and attached only with the bonding layer to the support layer become.
    As a result, the present invention will be explained in more detail with reference to the embodiment variants shown in the figures. Show it:
    1 shows a section through a wall according to the invention according to a variant with one-sided projecting rod dowels.
    2 shows a section through a wall according to the invention according to another embodiment variant with projecting dowels on both sides; and
    3 shows schematically an oblique view of a laminated wood element.
    Figure 1 shows a variant with one-sided projecting rod dowel. The carrier layer 1 and the wood layer 3 are spaced apart by dowels 7 in the form of dowels. The dowels 7 do not penetrate into the carrier layer 1, but merely rest on it. There are shown two rows of dowels 7, wherein the dowels 7 are mutually offset in the rows. In between, the connecting layer 2, in which lines 6 are laid open, opens up. They are laid especially close to the dowels 7 and are attached to the dowels 7, or attached to the wood layer 3. This has the advantage that the lines can be attached very easily, in contrast to a complicated attachment to a stone wall. The connecting layer 2 is poured out by grouting concrete. The wood layer 3 is realized by a laminated wood element 9. To the wood layer 3 includes an additional insulation layer 4, which is limited by a weather-resistant facade layer 5.
    Figure 2 shows a variant with both sides projecting rod dowels. The dowels 7 are on the support layer 1 as shown in the first embodiment shown. They are again arranged in mutually offset rows and extend from the bonding layer 2 via the wood layer 3 and through the additional insulating layer 4, the latter being realized as blow-in insulation. They stand on the facade layer 5 and thus prevent, in particular during construction, the moving together of the additional insulating layer 4 through the facade layer 5. The sinking of the insulation filling is prevented by a transverse support member 8 in the form of a carrier.
    FIG. 3 shows a laminated wood element 9, as are known, for example, from EP 1 097 032 B1. The composite plywood element 9 consists of several layers 12a, 12b, 12c, 12d, 12e and 12f of woods 3a, 3b, 3c, 3d, 3e and 3f. In this case, woods 3a, 3b and 3c or 3d, 3e and 3f of adjacent layers 12a, 12b, 12c and 12d, 12e and 12f have different directions. The woods 3c and 3d of the inner layers 12c and 12d are formed as posts, which are the same orientation. The thickness of the woods 3c, 3d of the inner layers 12c and 12d is greater than the thicknesses sa and sm of the woods 12a, 12b and 12e and 12f of the outer layers 3a, 3b and 3e and 3f, respectively.
    The layers 12a to 12f are connected to each other by dowels 7, which are inserted approximately normal to the layers 12a to 12f in the woods 3a to 3f. The dowels 7 are arranged like a grid.
    The thickness s ,, sa, sm of the layers 12a to 12f can be varied between 8 mm and 120 mm, depending on the intended use and static requirements, and combined as desired. A special quality of connection between the individual layers 12a to 12f and the dowels 7 is achieved by using wood moisture differences between dowels 7 and the woods 3a to 3f in a targeted manner. The dowels 7 are dried correspondingly stronger than the woods 3a to 3f and thereby absorb moisture from the surrounding wood to the moisture balance after anchoring. This causes a volumetric expansion and excellent wedging and pull-out strength of the dowels 7. The diameters of the dowels 7 can be between 8 and 40 mm, depending on the element thickness and use. The dowel length varies from the thickness of some layers 12 a to 12 f to the thickness of the entire laminated wood element 9.
    Several plywood elements 9 can be connected to each other by conventional tongue and groove, fly-over or dovetail milling, or by screws to roof and wall elements. Even corner joints are possible in this way. For corner joints in addition large, up to 100 mm thick dowels are used according to the described principle of targeted wood moisture difference.
