Description

The present invention relates to a wall element, with two spaced apart concrete layers and a plurality of connecting the two concrete layers connecting elements. Between the two concrete layers, a gap for filling with in-situ concrete is provided. The fasteners extend from one concrete layer through the gap to the other concrete layer. Furthermore, the present invention relates to a method for producing such a wall component and an anchor component for such a wall component.

Wall elements of the type mentioned are known in practice and are currently used mainly as raumabschließende components in commercial buildings. They are characterized by high resistance to weathering and aging as well as numerous possibilities for creative shaping. Such a wall component can for example be produced in a factory and transported to a construction site. There, several elements can be placed virtually in prefabrication next to each other and thereby connected to each other, that in-situ concrete is introduced into the gap. As a result, wall constructions can be performed much faster and cheaper. Not least because of this, multilayer wall elements also represent an economical alternative to the otherwise usual masonry constructions in residential construction.

From the US Pat. No. 6,263,638 B1 a wall element is known, in which the connecting elements are designed in the form of anchor elements made of glass fiber reinforced plastic. These connecting means are arranged distributed uniformly over the entire wall component, so that the two concrete layers are held together by flexible connecting means. As a result, the just-mentioned constraining stress is effectively prevented and a deformation between the two concrete layers is possible, at least within certain limits.

One of the two concrete layers can be assigned an insulating layer. The concrete layer and the adjacently arranged insulation layer are at a Overall structure usually arranged on the outside. This concrete layer has no supporting function. For removal of building loads or for building restraint only the Ortbetonergänzung in conjunction with the second concrete layer, which is located on the inside of the building, used. However, at the time of the US Pat. No. 6,263,638 B1 known wall construction, the risk that the outer concrete layer due to train / pressure loads due to wind and temperature gradient and a shear stress due to their own weight from the insulation layer or Ortbetonschicht could flake off. This risk can be counteracted by a denser arrangement of the connecting means, which, however, leads to higher production costs.

The present invention is therefore an object of the invention to provide a wall element of the type mentioned and further, on the one hand solves the above problems and on the other hand ensures a stable construction for years. Furthermore, the present invention has for its object to provide a method for producing a wall component and an anchor component for such a wall component, with which a wall component produced or suitable for this, which does not have the disadvantages listed above.

The wall element according to the invention of the type mentioned above solves the above problem by the features of claim 1. Thereafter, such a wall element is characterized in that for the removal of shear forces and / or increasing the stability of the wall member is provided at least one reinforcing means, which in the Has substantially plate-shaped anchor member, that the anchor member is disposed in a concrete layer and extending from the concrete layer into the gap and / or that in the intermediate layer at least one layer is provided that extends through the concrete layer and the layer at least one connecting element and that in the layer a reinforcing means is provided, which extends from the layer into a concrete layer.

According to the invention, it has first been recognized that at least one of the two concrete layers with the intermediate space provided for filling with in-situ concrete is, can be connected by the formed in the form of an anchor member reinforcing means, which significantly improves the static properties of the wall component. Thus, because of the reinforcing agent extending from the concrete layer into the intermediate layer, a stable connection is achieved between the concrete layer and the intermediate layer. In the following, the concrete layer, which results from the filling of the intermediate space with in-situ concrete, is referred to below as the intermediate layer. Alternatively or additionally, at least one layer may be provided in the intermediate layer where at least one connecting element extends through the concrete layer. In the layer, a reinforcing agent is provided, which extends from the layer into a concrete layer. This measure also improves or increases the connection between the intermediate layer and the concrete layer into which the reinforcing agent extends.

In principle, the armature component could be designed such that it extends from one concrete layer into the intermediate space and into the other concrete layer. As a result, the connection between the two concrete layers and the intermediate layer can be considerably increased. Due to the plate-like design of the anchor component can be absorbed or removed by the wall component shear forces. Alternatively, it is conceivable, although less preferred, for the armature component to be designed such that it extends from one concrete layer into the intermediate space and not into the other concrete layer.

The anchor component has a predefinable thickness, a predefinable length and a predeterminable width. The armature component is preferably now arranged in the wall component such that a longitudinal side of the armature component encloses a predeterminable angle with the surface of the wall component. This angle is preferably in a range between 0 and 90 degrees. Most preferably, the predeterminable angle is selected to be 90 degrees, so that the longitudinal side of the armature component is oriented perpendicular to the surface of the wall component. If the connecting elements are rod-shaped and also arranged with their longitudinal axis perpendicular to the surface of the wall component, in such a wall component, the connection between the two Concrete layers and the intermediate layer can be significantly increased. If the wall element has shear forces to remove, it could be provided that some of the anchor components or all anchor components at an angle of eg 45 degrees to the surface of the wall component to arrange. Thus, the shear members may receive the shear forces acting substantially along the orientation direction of the anchor members, the fasteners providing mainly sufficient bonding between the concrete layers and the intermediate layer.

The anchor component has a predefinable thickness, a predefinable length and a predeterminable width. The width is greater than the thickness of the anchor component. The armature component is preferably arranged in the wall component such that a broad side of the armature component encloses a predeterminable angle with the vertical. This angle is preferably in a range between 0 and 90 degrees. In other words, the armature component is arranged with respect to its plate shape oriented substantially in the vertical direction in the wall component, if the broad side of the armature component with the vertical forms an angle of 0 degrees. If the angle between the broad side of the armature component and the vertical is 90 degrees, the armature component is arranged substantially horizontally oriented in the wall component with respect to its plate shape.

According to a particularly preferred embodiment, a plurality of anchor components are at least partially distributed substantially uniformly in the wall component. In particular, each adjacent armature components have predetermined in the horizontal and / or vertical direction, substantially equal distances to each other. By a correspondingly dense distribution or arrangement of the anchor components can be guaranteed for a wall component of a predetermined size, a predetermined or required tensile stress between a concrete layer and the intermediate layer or between the two concrete layers. The anchor components can also transmit shear forces with appropriate arrangement. As a rule, a symmetrical arrangement of the armature components is provided with an arrangement which can be predetermined in each case in the horizontal and / or vertical direction, adjacent armature components in each case having substantially equal distances from one another.

The anchor components preferably have a predeterminable arrangement to the connecting elements, which are preferably arranged in alignment in the horizontal and / or vertical direction to each other. Accordingly, some of the connecting elements and some of the armature components may be arranged substantially on a straight line. Alternatively or additionally, the arrangement of the armature components could also be provided offset from the arrangements of the connecting elements. It is conceivable that the anchor components in the horizontal and / or vertical direction are arranged centrally offset from the connecting elements.

The anchor component preferably has at least one recessed and / or protruding region, for example in the form of grooves, recesses, grooves or recesses. Preferably, the recessed and / or protruding region are arranged in the installed state in the wall element in a concrete layer or in the intermediate space. In principle, the armature component could have a surface profile such that a force transmission between a concrete layer and the armature component is thereby favored. In this context, the property of the concrete used for the concrete layer or the intermediate layer will usually also have to be taken into account and selected in such a way that in interaction between surface profile of the anchor component and type of concrete the highest possible power transmission between concrete layer and / or intermediate layer and anchor component is possible.

According to a preferred embodiment, the armature component has a substantially rectangular cross-section. This relates in particular to the longitudinal direction of the plate-shaped armature component. Possibly. At least one corner region of the rectangular cross-section can be rounded. The anchor component preferably has a shoulder part. The shoulder part could be provided integrally on the anchor component. However, the shoulder part is preferably made of plastic, for example, and fastened to the anchor component as a further component. The shoulder part is arranged on the anchor component in such a way that the anchor component can be introduced into an insulating layer or concrete layer only up to a predefinable depth until, namely, the shoulder part comes into contact with the surface of the insulating layer or the concrete layer. In a comparable manner, the anchor component (and also the connecting element) could have a plate-shaped head part, which is designed as a separate, on Anchor member (and the connecting element) attached component is formed. The anchor member can be erected with the headboard upright on the bottom of a mold and positioned accordingly, in which the concrete for the production of the concrete layer with the anchor member is poured.

In particular, if the wall element is to have heat-insulating properties, an insulating layer could be provided according to a preferred embodiment. Such an insulating layer could be arranged in the intermediate space and / or adjacent to a concrete layer. The insulating layer could have a polystyrene hard foam. Usually, an insulating layer made of polystyrene rigid foam is produced by extrusion.

According to a particularly preferred embodiment, at least one layer is applied to the side facing away from the concrete layer of the insulating layer. Through the concrete layer, the insulating layer and the layer extending (at least) a connecting element. As a result, a solid composite of the layer, the insulating layer and the concrete layer is given, if - which is usually the case - the layer is connected to the connecting element in a comparable manner, as is the case with the connecting element with the concrete layer. In the layer, a reinforcing means is provided which extends out of the layer and into the gap. The reinforcing means is sized to extend into the gap and preferably into the other concrete layer. Alternatively, the reinforcing means could be sized so that it does not extend into the other concrete layer.

Most preferably, at least two reinforcing means are provided, each of which has an attachment point for a crane at its region extending out of the layer, by means of which the concrete layer with the insulating layer and the layer can be lifted. It could also have only one reinforcing means at least two attachment points for a crane. Preferably, an attachment point is detachable from the reinforcing means.

In that regard, at the attachment points of the reinforcing agent, which extend out of the layer, each a hook of a crane can be attached. As a result, for example, the concrete layer can be raised and / or turned with the reinforcing agent in the manufacture of the wall component to approximate this already hardened concrete layer to a not yet hardened concrete layer, thus producing the wall component. At the or the attachment points of the reinforcing means, the finished wall element could continue to be transported and / or raised, for example, to position the wall element at its final installation point.

Now, the layer could be provided only in places, mostly or completely on the surface of a concrete layer or on the insulating layer or this covering. The layer could furthermore have a smaller thickness than the thickness of the intermediate space or of the intermediate layer. Finally, the layer could be dimensioned such that a bond between the concrete layer, possibly provided insulation layer, layer and reinforcing agent is formed, which is sufficient for the intended purpose, for example, for a turning process in the manufacture of the wall component or for transporting an entire wall component.

The layer could have concrete and contain, for example, further additives. Alternatively, or the layer could be made entirely of concrete, for example of a similar composition as that of the concrete layer and / or the in-situ concrete. The layer could also be made of plastic.

Preferably, at least one reinforcing means is provided, which is arranged in a concrete layer and this largely enforcing. This is to be understood in particular that the reinforcing means completely or at least almost completely passes through the concrete layer. Thus, the reinforcing agent also has the function of a reinforcing agent. In other words, a reinforcing means over the entire region of the inner or outer surface of the wall member is arranged, wherein at the edge region under certain circumstances no reinforcing means could be provided. This edge region could make up to 20% of the entire surface of the wall element.

At least one of the two concrete layers can be connected to the space provided for filling with in-situ concrete by the reinforcing means, which considerably improves the static properties of the wall element. Thus, on the one hand, this concrete layer is improved in its static properties, on the one hand, because of the reinforcing means, which for the most part extend through the concrete layer. On the other hand, a stable connection between the concrete layer and the intermediate layer is achieved with the same reinforcement due to its special design, namely to extend at least partially from the concrete layer into the gap. In this case, the static properties of the intermediate layer can be improved solely on the basis of such a reinforcing means, so that the intermediate layer can also make a contribution to the removal of forces.

So is due to the fasteners, as for example from the US Pat. No. 6,263,638 B1 are known, and without the reinforcing means before a flexible connection between the two concrete layers. There are therefore - within certain limits - deformations between the two concrete layers possible, so that this tensile stresses are largely avoided. In addition, in the case of a wall construction filled with in-situ concrete, an improved connection between the in-situ concrete layer and the respective concrete layer is given due to the reinforcing means. As a result, the connecting elements no longer have to be arranged quite so dense, whereby in this respect the manufacturing costs can be reduced. Due to the improved connection of the layers with one another, any construction-law requirements which may be provided can be met, so that, for example, the wall component according to the invention can also be advantageously used in residential construction. The wall component in the sense of the present invention can also be used for a ceiling or floor construction.

In principle, the reinforcing means arranged in the concrete layer could be designed in such a way that it extends from the concrete layer into the interspace up to the other concrete layer, even completely penetrating it in some areas.

Preferably, however, it is provided that the reinforcing means arranged in the concrete layer is designed in such a way that it does not form the other one Concrete layer extends into it and thus does not connect a concrete layer with the other concrete layer. This will be the case in particular if the reinforcement is made of metal or has a material with a high thermal conductivity. Accordingly, the reinforcement does not contribute to a thermal bridge and it is in a particularly advantageous manner to produce a stable wall construction, which also has very particularly good heat insulating properties.

According to a particularly preferred embodiment, the reinforcing means comprises a reinforcing mat. The reinforcing mat is shaped such that it extends at least partially out of the concrete layer and into the intermediate space. For differently designed wall elements differently trained reinforcing mats could be provided, which in terms of their concrete design, the concrete layer and the respective intermediate layer of a wall component predetermined total thickness penetrates almost in a comparable manner and at a comparable rate. Specifically, the reinforcing mat could be in the form of a metal grid. Such metal grids are conventionally used as reinforcing means in the prior art and usually have a substantially planar shape. In order for such a reinforcement mat for a wall element according to the invention can be used, for example, a conventional reinforcing mat could subsequently be correspondingly bent, pressed or shaped, so that the reinforcing mat extends in the bent portion of the concrete layer in the space of the wall component. Alternatively, a production of a correspondingly shaped reinforcing mat from the beginning conceivable.

The reinforcing mat could be substantially wavy, rectangular or sawtooth shaped, comparable to a shape of a wave, rectangle or saw tooth function (especially in the mathematical sense). If the reinforcing mat is designed in the form of a metal grid, for example, the unidirectional metal bars could be wave-shaped or rectangular, and substantially straight-formed metal bars could be welded transversely thereto to the wave-shaped or rectangular metal bars. Such a reinforcing mat then constitutes a one-piece or a permanent one Correspondingly, a metal grid formed in a direction substantially wave-shaped, rectangular or sawtooth-shaped would be formed. A reinforcing mat formed in this way can now be arranged in the wall component such that the wave-shaped or rectangular metal rods are arranged essentially horizontally or in a horizontal plane, so that a wave-shaped or rectangular "bulge" of the reinforcement mat in a state installed in the wall component extends substantially vertically. A built-in form of the reinforcing mat rotated by a predefinable angle and in particular by 90 degrees is also conceivable, if required by the application.

The reinforcing mat could be shaped such that at least two portions of the reinforcing mat extend out of the concrete layer and into the gap. In general, however, several areas of the reinforcing mat will extend out of the concrete layer into the gap.

In principle, it is also conceivable that the reinforcing mat is in each case substantially wave-shaped, rectangular or sawtooth-shaped in two different directions and that at least two regions of the reinforcing mat extend out of the concrete layer and into the intermediate space. Usually, a reinforcing mat formed in this way can not be produced from the subsequent bending or pressing of a substantially flat metal grid. Rather, it will be necessary to connect correspondingly shaped individual components together to produce a corresponding reinforcement mat. By using such a shaped reinforcing mat, an even more stable construction of the wall element can be achieved, which could be helpful in corresponding applications.

In a preferred embodiment, the reinforcing mat occasionally on projecting bracing elements. The bracing elements are in this case arranged such that they extend out of the concrete layer and into the intermediate space. The bracing elements could for example be formed integrally with the reinforcing mat. This could be realized, for example, by separating individual predeterminable metal bars of a metal grid, with part of the severed metal bar being bent out of the metal grid plane.

The bracing elements could be substantially rod-shaped. For example, a bracing element could have a first and a second area. The first region could be arranged at a predeterminable angle to the second region. Thus, a substantially C-, L-, U-, O- or Z-shaped bracing element can be formed, wherein in the latter form, a third region adjoins the second region and also provides a predeterminable angle between the second and the third region is. The C-, L-, U-, O- or Z-shaped bracing element, if it lies in one plane, could be oriented either horizontally, vertically or at a predeterminable angle to the vertical in a state installed in the wall component. The bracing element could also have a part which extends out of a plane, so that the bracing element extending into the intermediate space extends overall in three spatial directions.

Now, another functionality could be provided for the reinforcement. Namely, the reinforcing means could have at least two attachment points for a crane, by means of which the concrete layer can be lifted. In that regard, the reinforcing means may serve with at least two extending from the concrete layer areas each as an attachment point for a hook of a crane. As a result, for example, the concrete layer with the reinforcement in the manufacture of the wall member raised and / or turned to this already hardened concrete layer to a not yet hardened concrete layer approach, thus producing the wall element. At the or the attachment points of the reinforcing means, the finished wall element could continue to be transported and / or raised, for example, to position the wall element at its final installation point. Such an attachment point is preferably made detachable from the reinforcement.

As an alternative or in addition to the above-mentioned measures, at least one reinforcing means can be provided which is arranged only in the intermediate space and which does not extend into either of the two concrete layers. Such a reinforcing agent thus serves only to increase the stability of the intermediate layer of the wall component and does not improve the connection between a concrete layer and the intermediate layer.

As only in the intermediate space arranged reinforcing means could be provided substantially rod-shaped reinforcing elements. On a rod-shaped reinforcing element bracing elements may be provided. This could be metal or steel rods of a predeterminable diameter. These reinforcing means or the reinforcing elements could be arranged substantially vertically in the intermediate space and / or have a predeterminable angle to the vertical. This may depend on the particular use of the respective wall component. If the reinforcing elements are arranged at a predeterminable angle to the vertical in the intermediate space, it is also possible for shearing forces to occur which essentially occur in a direction parallel to the orientation of the reinforcing elements.

Concretely, the at least one reinforcing agent or the reinforcing elements could be introduced locally before and during the filling process of the in-situ concrete in the space of the wall component. In the simplest case, the reinforcing elements of suitable length (preferably finally with one - eg the upper edge of the wall component) are introduced into the intermediate space, wherein the reinforcing elements on the (connecting the two concrete layers and thus the gap passing through) fasteners in a vertical position and / or can be ajar aligned at almost any angle. However, it could alternatively be provided in the lower region of the wall component at least one means with which the reinforcing elements can be aligned in their final installation position. Such an agent could, for example, be an isolated wooden board with corresponding holes through which the reinforcing elements are inserted. Alternatively or additionally, at least one holding means could be provided, which engages in each case on an upper region of a reinforcing element and is preferably supportable on the wall component in order to align the reinforcing elements in their final installation position.

The reinforcing agent and / or the reinforcing agent and / or the reinforcing mat and / or the bracing elements and / or the Reinforcing elements could each have steel or be made of - preferably stainless or low-corrosion - steel.

A connecting element is substantially rod-shaped or anchor-shaped, such as one of the US Pat. No. 6,263,638 B1 known connection element.

To the wall components used in housing construction increased demands are made in terms of thermal protection. In this context, the effect of thermal bridges in exterior wall surfaces is also becoming increasingly important. The from the DE 100 07 100 A1 known fasteners are made of either stainless steel or non-corrosion resistant black steel.

Since these fasteners extend from the outer layer to the inner concrete layer, thermal bridges are automatically formed thereby, resulting in poorer thermal insulation. By the from the US Pat. No. 6,263,638 B1 known connecting means made of glass fiber reinforced plastic no thermal bridges are formed, so that in this way a significantly improved thermal insulation compared to that of DE 100 07 100 A1 known wall / ceiling component is achieved. The thermal conductivity of lattice girders made of stainless steel is approximately 17 W / (mK), for reinforcing steel approximately 50 W / (mK). The thermal conductivity of glass fiber reinforced plastic connectors from the US Pat. No. 6,263,638 B1 is only 0.5 W / (mK), which corresponds to a negligible thermal conductivity compared to that of the reinforcing steel.

Therefore, it is provided in a very particularly preferred embodiment that the connecting elements have a medium to low thermal conductivity. This could be achieved by an appropriate choice of material, for example, if the connecting elements are made of fiber-reinforced plastic. In that regard, a stable wall construction can be produced in a particularly advantageous manner, which moreover has very good heat insulating properties.

A connecting element could have a surface profile such that thereby a force transmission between a concrete layer and the Connecting element is favored. This could be realized for example by grooves or depressions and / or by protruding areas. In this context, as a rule, the property of the concrete used for the concrete layer or the intermediate layer to be considered and selected such that in interaction between the surface profile of the connecting element and type of concrete as high a power transfer between the concrete layer and / or intermediate layer and connecting element is possible.

According to a preferred embodiment, the connecting elements are substantially rod-shaped and arranged in the wall component, that their longitudinal axis with the surface of the wall component - in particular to the vertical - include a predetermined angle, which is preferably in a range between 30 and 90 degrees. As a rule, the connecting elements are installed oriented perpendicular to the outer surface of the wall component, so that they hold together the individual layers as connecting anchors.

Preferably, the connecting elements are at least partially distributed substantially uniformly in the wall component. In particular, each adjacent connecting elements have predetermined in the horizontal and / or vertical direction, substantially equal distances from each other. By a correspondingly dense distribution or arrangement of the connecting elements, a predeterminable or required tensile stress between the two concrete layers can be ensured for a wall component of a predeterminable size. As a rule, a symmetrical arrangement of the connecting elements is provided with an arrangement which can be predetermined in each case in the horizontal and / or vertical direction, wherein adjacent connecting elements in each case have substantially equal distances from one another.

In a very particularly preferred embodiment, a connecting element and / or an anchor component comprises plastic with unidirectionally or multidirectionally arranged fibers, which comprise in particular glass, basalt or carbon fibers, preferably boron-free silicate glass fibers, wherein the plastic in particular polyester, vinyl ester or Polyurethane has. These Materials have a high tensile strength and are therefore particularly suitable for this application. When selecting a material for the fastener and / or the anchor member, it should be noted that they are resistant to moisture and / or high pH environments. In particular, the low thermal conductivity of these materials is of very particular advantage, as a result, the wall construction has no thermal bridges and a very high thermal insulation effect is possible.

In procedural terms, the object mentioned above is achieved by the features of claim 21. The wall element - in particular according to one of claims 1 to 20 - has two spaced-apart concrete layers, an insulating layer and a plurality of connecting the two concrete layers connecting elements. The insulating layer is disposed in the space and adjacent to a concrete layer. Between the two concrete layers, a gap for filling with in-situ concrete is provided.

The method according to the invention is characterized in that connecting elements are introduced through the insulating layer in such a way that the connecting elements protrude on both sides of the insulating layer. A first concrete layer is produced. On the not yet cured first concrete layer, the insulating layer is applied such that the connecting elements extend into the first concrete layer and the insulating layer is disposed adjacent to the first concrete layer. On the side of the insulating layer facing away from the first concrete layer, at least in places a layer is applied where at least one connecting element protrudes from the insulating layer. At least one reinforcing agent is introduced into the uncured layer. A second concrete layer is produced. After curing of the first concrete layer and the layer, this is approximated together with the insulating layer to the second, not yet cured concrete layer, that the connecting elements and the at least one reinforcing agent extend into the second concrete layer.

A wall component according to the invention can also be produced according to the method for producing a wall component-in particular according to one of claims 1 to 20-according to claim 22. The wall element has two spaced apart concrete layers, an insulating layer and a plurality of connecting the two concrete layers connecting elements. The insulating layer is disposed in the space and adjacent to a concrete layer. Between the two concrete layers, a gap for filling with in-situ concrete is provided. The method according to the invention is characterized in that connecting elements are introduced through the insulating layer in such a way that the connecting elements protrude on both sides of the insulating layer. At least one anchor component is introduced into the insulating layer such that the at least one anchor component protrudes from one side of the insulating layer. A first concrete layer is produced. The insulating layer together with connecting elements and the at least one anchor component are applied to the not yet hardened first concrete layer in such a way that the connecting elements extend into the first concrete layer and that the side of the insulating layer from which the at least one anchor component protrudes from the insulating layer from the first concrete layer turned away. The insulating layer is in this case arranged adjacent to the first concrete layer. A second concrete layer is produced. After curing of the first concrete layer, this is approximated together with the insulating layer to the second, not yet cured concrete layer, that the connecting elements and the at least one anchor member extending into the second concrete layer. The connecting elements are dimensioned such that a gap remains between the second concrete layer and the insulating layer. In that regard, the connecting elements are used to determine the width of the gap, so have a spacer function. Also, this manufacturing method is adapted to the production of wall components with a turning table and is thus suitable for production in a factory.

Such a wall component with an insulating layer, could be made on site with a method of manufacturing a wall component - in particular according to one of claims 1 to 20 - according to claim 23. For this purpose, the connecting elements are introduced through the insulating layer such that the connecting elements protrude on both sides of the insulating layer. At least one anchor component is introduced into the insulating layer such that the at least one anchor component protrudes from at least one side of the insulating layer. A first concrete layer is produced. On the not yet cured first concrete layer, the insulating layer including fasteners and the at least an anchor member is applied such that the connecting elements and the at least one anchor member extend into the first concrete layer. The length of the part of the connecting elements, which faces the first concrete layer, is dimensioned such that the gap remains between the first concrete layer and the insulating layer. In that regard, the connecting elements are used to determine the width of the gap, so have a spacer function. On the side of the insulating layer facing away from the first concrete layer, a second concrete layer is produced, wherein a corresponding shape could be provided for the second concrete layer and wherein the connecting elements and optionally the at least one anchor component extend from the insulating layer into the second concrete layer. In this manufacturing method of the wall element none of the concrete layers are turned. In that regard, one is not dependent on the use of a turning table. The wall element could for example be made on site on the site. Also, the first concrete layer need not be cured before the second concrete layer is made.

If the wall element does not have an insulating layer, a wall element according to the invention can be produced by the method for producing a wall element according to claim 24. Accordingly, the inventive method for producing a wall component according to one of claims 1 to 20 is used. The wall component has two spaced-apart concrete layers and a plurality of connecting the two concrete layers connecting elements. Between the two concrete layers, a gap for filling with in-situ concrete is provided.

The inventive method is characterized in that a first concrete layer is produced, in which the connecting elements and at least one anchor member are introduced. Thus, the first concrete layer could be made by pouring concrete into a mold in which the fasteners and the at least one anchor member are pre-positioned. The at least one anchor component is in this case arranged or dimensioned such that it protrudes from the first concrete layer.

A second concrete layer is produced. After curing of the first concrete layer, this is approximated to the second, not yet cured concrete layer - For example, with a turning table - that the connecting elements and optionally the at least one anchor member extend into the second concrete layer. After the second concrete layer has cured, the wall element is completed and can then be transported to a construction site and / or installed on a building, where then the gap is filled with in-situ concrete. This manufacturing process is adapted to the production of wall components with a turning table. Here, the one part of the wall component is turned in the production and almost congruent approximated to the other part of the wall component and connected to it. This production method is thus suitable for production in a factory.

Since a method for producing a corresponding wall component opens up at least largely to a person skilled in the art and the mode of operation of a wall component according to any one of claims 1 to 20, reference is made to the preceding part of the description with respect to the inventive production method for avoiding repetitions.

At least one reinforcing means extending into none of the two concrete layers can be introduced into the intermediate space, for example after the positioning of the respective wall component and before or during the filling of the in-situ concrete into the interspace of the respective wall component.

In the production of a concrete layer, a reinforcing agent could be introduced into the concrete layer, which is either exclusively arranged in the concrete layer or which extends out of the concrete layer and into the intermediate space.

With regard to an anchor component, the object mentioned at the outset is solved by the features of patent claim 26. Accordingly, an anchor member as reinforcing means in a concrete layer of a wall element according to one of claims 1 to 20 can be introduced. The anchor component according to the invention is characterized by a substantially plate-like configuration and by plastic with unidirectionally or multidirectionally arranged fibers, which in particular glass, basalt or carbon fibers, preferably boron-free silicate glass fibers comprise, wherein the plastic in particular polyester, vinyl ester or polyurethane. In other words, according to the invention, a suitably designed anchor component is used as reinforcing element in a concrete layer of a wall component according to one of claims 1 to 20.

The anchor component preferably has at least one recessed and / or protruding region which is preferably arranged in the concrete layer or in the interspace in the state installed in the wall component. The anchor component could have a substantially rectangular cross-section with preferably rounded corner regions. The anchor component could have a head and / or a shoulder part.

An innovative wall component has two spaced concrete layers and a plurality of connecting the two concrete layers connecting elements. Between the two concrete layers, a gap for filling with in-situ concrete is provided. The fasteners extend from one concrete layer through the gap to the other concrete layer.

Identical or similar components are identified in the figures with the same reference numerals. The in the Fig. 1 to 3 and 10 to 12 wall elements shown are only shown in the clipping. The border areas of these detail sections are to be presented accordingly.

Fig. 1 shows in a cross-sectional view seen from the side of a wall component 1, which has two spaced-apart concrete layers 2, 3. The concrete layers 2, 3 are connected to a plurality of connecting elements 6, wherein the connecting elements 6 extend from the concrete layer 2 through the intermediate space 5 to the concrete layer 3. That in the Fig. 1 to 3 shown connecting element 6 has a length of 250 mm. That in the Fig. 1 to 3 wall element 1 shown in detail has a length of 3600 mm and a height of 2200 mm.

The connecting elements 6 are substantially rod-shaped and arranged in the wall component 1 such that their longitudinal axis with the surface of the wall component 1 include a predetermined angle, which is 90 degrees. The connecting elements 6 are distributed substantially uniformly in the wall component 1. Adjacent connecting elements 6 each have predeterminable, substantially equal distances from each other in the horizontal and vertical directions. The connecting elements 6 have unidirectionally arranged, boron-free silicate glass fibers with a polyester matrix.

Between the concrete layer 2 and the concrete layer 3, a gap 5 is provided for filling with in-situ concrete. The individual layers of the wall component 1 off Fig. 1 have in detail the following thicknesses: Concrete layer 2: 60 mm Gap 5: 140 mm Concrete layer 3: 50 mm.

That in the Fig. 1 to 3 shown wall component 1 has to remove shear forces and / or to increase the stability of the wall component 1 to a reinforcement 7, which is arranged in the concrete layer 2 and this largely enforcing. The reinforcement 7 is designed such that it extends at least partially from the concrete layer 2 into the intermediate space 5. These areas are in Fig. 2 designated by the reference numeral 9. In Fig. 3 is indicated by the additional lines 10, 11 and 12, that according to Fig. 2 Reinforcing means 7 shown in the plan view extends from the concrete layer 2 into the intermediate space 5 and thus into the area 9. Furthermore, a plurality of reinforcing means 8 are provided, which are arranged in the intermediate space and which do not extend into any of the two concrete layers 2, 3.

However, the reinforcing means 7 does not extend from the concrete layer 2 into the intermediate space 5 in the concrete layer 3. This would be conceivable in principle, especially since then the two concrete layers 2, 3 and the intermediate layer 5 can be stably connected to each other by only one reinforcement 7. For reasons of heat insulation, however, a connection of the two concrete layers 2, 3 with the reinforcing means 7 is less preferred.

The reinforcement 7 from the Fig. 1 to 3 is formed in the form of a reinforcing mat and is also indicated by the reference numeral 7 for the sake of simplicity. The reinforcing mat 7 is formed in the form of a metal grid and is shaped such that it extends at least partially - namely in the areas 9 - out of the concrete layer 2 and into the intermediate layer 5. As can be seen from the cross-sectional view and the view from above according to Fig. 2 detects the wall element 1, the reinforcing mat 7 has a sawtooth shape. With the "saw teeth" or the triangular projections, a part of the reinforcing mat 7 extends almost to the middle of the gap 5, namely in the areas 9. The triangular projections are arranged almost equidistant from each other.

The in the Fig. 1 to 3 and in the Fig. 4 Reinforcement mat 7 shown in each case is only shaped sawtooth in one direction. In principle, however, it would also be conceivable for the reinforcing mat 7 to be wave-shaped, rectangular or sawtooth-shaped in two independent directions and to extend correspondingly with a plurality of regions into the intermediate space of the wall component. In Fig. 4 three dash-dotted lines 13 are indicated, along which also each have a "sawtooth" or a survey from the ground plane of the reinforcing mat 7 shown there in the in Fig. 4 can not extend shown intermediate layer. In this case, the reinforcing mat 7 would have "saw teeth" along two mutually perpendicular directions at predeterminable distances.

Fig. 4 shows a perspective view of a first embodiment of a formed in the form of a reinforcing mat 7 reinforcement. Furthermore, a plurality of connecting elements 6 are shown, as they are provided in the installed state in the wall component 1. In Fig. 4 no concrete layers are shown. In this reinforcing mat 7, the distance between two adjacent projections 10, 11, 12 is greater than in the reinforcing mat 7 of the embodiment according to Fig. 2 ,

Fig. 5 shows a further embodiment of a trained in the form of a reinforcing mat 7 reinforcement. Also in Fig. 5 are shown in the perspective view shown there, the connecting elements 6, which the in Fig. 5 Connect concrete layers not shown together. The reinforcement mat 7 off Fig. 5 has a substantially planar lattice structure. Occasionally integrally formed with the reinforcement mat 7 struts 13 are provided. The bracing elements 13 are arranged such that they extend out of the concrete layer and into the intermediate layer. The bracing elements 13 can be formed in a simple manner by the fact that from a conventional, a planar grid structure having reinforcing mat 7 at corresponding points 21, the intersections of the intersecting bars are separated and the four rod-shaped bars - then the strut elements 13 forming - are bent outwards , At the reinforcement mat 7 off Fig. 5 The strut elements 13 are perpendicular to the plane of the reinforcing mat 7. For example only, a second region 15 is provided on one of the strut elements 13, which is arranged perpendicular to a first region 14 of the strut element 13. In that regard, the substantially L-shaped configuration of the bracing element 13 contributes to the fact that an increased tensile force connection can be achieved between the concrete layer in which the reinforcing mat 7 is arranged and the intermediate layer. Occasionally, an annular component (not shown) could also be welded to a bracing element 13, so that an attachment point for a crane is thereby formed, by means of which the concrete layer can be lifted. Of the attachment points are at least two, preferably provided three, so that a controlled lifting of the concrete layer or the wall element is possible.

In the Fig. 1 to 3 Furthermore, reinforcing means 8 are shown, which are arranged only in the intermediate space 5 of the wall component 1. The reinforcing means 8 are substantially rod-shaped reinforcing elements and are also marked with the reference numeral 8. The in the Fig. 1 to 3 shown reinforcing elements 8 are arranged substantially vertically. In Fig. 3 Examples of arrangements of further reinforcing elements 8 'and 8 "are shown which have a predeterminable angle to the vertical, in which case the reinforcing element 8' is located between in each case two adjacently arranged and vertically aligned connecting elements 6. The reinforcing element 8" is at an angle is arranged at about 45 degrees to the vertical in the wall component 1 and is inserted obliquely at this angle between the intermediate space 5 passing through connecting elements 6 before the in-situ concrete is introduced into the intermediate layer 5 of the wall element 1. The reinforcing element 8 "is designed to be longer than a reinforcing element 8, since this extends due to the oblique arrangement to the vertical over a longer range in the wall component 1. Basically, the reinforcing elements 8, 8 'and 8" on site and before the refilling of the Interspace 5 introduced with in-situ concrete.

If the reinforcing elements 8 are to be arranged substantially vertically, they could be ajar against a connecting element 6 or a series of several vertically oriented connecting elements 6, so that no additional holding devices are provided, with which the reinforcing elements 8 in their vertical orientation during the filling process of the intermediate layer 5 are to be kept with in-situ concrete.

The Fig. 6 to 8 each show embodiments of reinforcing means 7 in the plan view, comparable to the view of the reinforcement 7 from FIG. 2 , Specifically, the reinforcement 7 is according to Fig. 6 comparable to the reinforcement of the Fig. 1 to 3 and 10 educated. Accordingly, the reinforcing means 7 has a substantially flat-shaped reinforcing mat or a reinforcing grid on which the "saw teeth" are welded. Thus, in the reinforcing means 7, there are Fig. 6 always a continuous area 16 of the reinforcing grid.

Fig. 7 shows in a plan view of an embodiment of a reinforcing mat 7, which is comparable to the in Fig. 4 shown reinforcing mat 7 is formed. The reinforcement mat 7 off Fig. 7 differs from the reinforcement mat Fig. 6 essentially in that the reinforcement mat 7 off Fig. 7 has no continuous area 16. The in the 6 and 7 shown reinforcing mats 7 have substantially a sawtooth shape, the details "saw teeth" have a predetermined distance from each other and depending on the wall element in which you are installed, with a predetermined height of the ground plane of the reinforcing mat 7 into the space of the wall component extend.

Fig. 8 shows an embodiment of a reinforcing mat 7 in a plan view, which has a waveform. Concretely, by pressing a conventional planar reinforcing grid, the wavy reinforcing mat 7 could be made Fig. 8 be made.

Fig. 11 shows a further embodiment of a wall component 1 according to the invention in a cross-sectional view from above. The wall element 1 has two concrete layers 2, 3 and an insulating layer 4. Between the insulating layer 4 and the concrete layer 2, the gap 5 is arranged. The concrete layers 2 and 3 are connected to each other with connecting elements 6. On the concrete layer 3 side facing away from the insulating layer 4 are of the in Fig. 11 shown section of the wall element 1 three layers 17 applied. Through the concrete layer 3, the insulating layer 4 and the layer 17, a plurality of connecting elements 6 extend, wherein according to the view Fig. 11 two connecting elements 6 extend through a respective layer 17. In the layer 17 is in each case a reinforcing means 18 is provided or anchored. The reinforcing means 18 extends out of the layer 17 and into the gap 5 and into the concrete layer 2. In the concrete layer 2 im reinforcing means 18 are also arranged, which extend out of the concrete layer 2 and into the intermediate space 5. A reinforcing means 18 could be in the form of a lattice girder. Although in Fig. 11 the wall component 1 is shown with an insulating layer 4, it is also conceivable in a comparable manner to provide a wall component 1 or such an insulating layer. In this case, the layer 17 would be arranged immediately adjacent to the concrete layer 3.

A hook of a crane can be hooked onto at least two reinforcing means 18 on its area extending out of the layer 17, so that the composite of concrete layer 3, insulating layer 4, connecting elements 6, layer 17 and reinforcing means 18 are lifted during the production of the wall element 1 can.

The layer 17 is in Fig. 11 only in places provided on the surface of the insulating layer 4. The layer 17 could also be arranged across the entire surface of the insulating layer 4. The thickness of the layer 17 is less than the thickness of the intermediate layer 5 or the thickness of the concrete layer 2 or 3. The layer 17 of Fig. 11 is made of concrete.

The reinforcing means 7, the reinforcing means 18, the bracing elements 13 to 15, the reinforcing elements 8 and the reinforcing mat 7 are made of steel.

Fig. 9 shows a substantially rod-shaped or anchor-shaped connecting element 6, as in the wall component 1 according to the Fig. 1 to 3 . 10 or 11 could be installed. The connecting element 6 according to Fig. 9 is similar to the one in US Pat. No. 6,263,638 B1 formed connecting element and can in a comparable manner in the in the Fig. 10 or 11 wall element 1 shown with insulating layer 4 are installed. The connecting element 6 has a surface profile such that in this way a force transmission between a concrete layer 2, 3 and / or 5 and the connecting element 6 is favored. The surface profile has protruding areas 19 and depressions 20.

Fig. 10 shows a wall component 1 with an insulating layer 4, which is arranged in the intermediate space 5 and adjacent to the concrete layer 3. The insulating layer 4 has an extruded polystyrene rigid foam. The concrete layer 3 is in a building that is built with several wall elements 1, the outer wall. For the sake of simplicity, the concrete layer 3 will also be referred to below as the outer concrete layer 3. Accordingly, the concrete layer 2 is the inner concrete layer of a building to be manufactured and is referred to as inner concrete layer 2.

The outer concrete layer 3 is assigned to the insulating layer 4, in the form that the insulating layer 4 and the concrete layer 3 have an adhesive bond. Between the insulating layer 4 and the inner concrete layer 2, a gap 5 is provided for filling with in-situ concrete. The individual layers of the wall component 1 off Fig. 10 have in detail the following thicknesses: outer concrete layer 3: 60 mm Insulation layer 4: 60 mm Gap 5: 140 mm Inner concrete layer 2: 50 mm.

This in Fig. 10 shown wall component 1 has a length of 3600 mm. The connecting elements 6 have a length of about 300 mm.

The concrete layers 2, 3 are connected to a plurality of connecting elements 6, wherein the connecting elements 6 extend from the outer concrete layer 3 through the insulating layer 4 and the intermediate space 5 to the inner concrete layer 2.

The connecting elements 6 have a low thermal conductivity, namely a value of 0.5 W / (mK). Accordingly, the wall component 1 has virtually no thermal bridge, which could result, in particular, from the connecting elements 6. This leads to a wall component 1, with an overall particularly low thermal conductivity. The reinforcing agent 7 provided in the concrete layer 2 and in the intermediate layer 5 has a thermal conductivity of 17 W / (mK) and is made of stainless steel. In the intermediate layer 5 also reinforcing means 8 are provided, in each case a reinforcing means 8 between two adjacent connecting elements 6. In the wall element 1 according to the Fig. 1 to 3 in each case two reinforcing means 8 are arranged between each two adjacent connecting elements 6.

In Fig. 12 is a cross-sectional view and seen from the side of another embodiment of a wall component 1 according to the invention shown. This wall element 1 has two concrete layers 2, 3 and the intermediate space 5. The two concrete layers 2, 3 are with connecting elements 6 connected. In the wall element 1 anchor members 22 are further provided which each extend from the one concrete layer 2 through the gap 5 in the second concrete layer 3. An embodiment of an anchor member 22 is in the Fig. 14 to 16 shown. The longitudinal side 23 of the anchor member 22 is in this case perpendicular to the surface of in Fig. 12 shown wall component 1 is arranged. The broad side 24 of the armature component 22 is oriented in the direction of the vertical. Furthermore, 5 reinforcing means 8 are provided in the gap, which do not extend into one of the two concrete layers 2, 3 and which comparable to the embodiment according to Fig. 1 are formed in the form of rod-shaped reinforcing elements. In the Fig. 12 shown anchor members 22 are arranged in the vertical direction in alignment and alternately with the connecting elements 6.

Fig. 13 shows a perspective view of an embodiment of a reinforcing mat 30 with a plurality of anchor components 22 and connecting elements 6 as they are provided in the installed state in a wall component 1. In Fig. 13 no concrete layers are shown. The connecting elements 6 are formed slightly shorter than the armature components 22. Accordingly, the longitudinal side 23 of the armature components 22 is smaller than the length of the connecting elements 6. In each case two adjacent connecting elements 6 and two adjacent armature components 22 each have substantially the same distance in the horizontal direction. The same applies in the vertical direction. The anchor components 22 off Fig. 13 are arranged with respect to the broad side 24 oriented in the horizontal direction.

The Fig. 14 to 16 show an anchor member 22 from three different views. The armature component 22 has a longitudinal side or a length 23, a broad side or a width 24 and a thickness 25. Furthermore, the anchor member has two recesses 26, 27, which are provided on each side of the shoulder part 28. The armature component 22 could thus be made in the wall component 1 Fig. 12 be installed, that the recess 26 is disposed in the concrete layer 2 and the recess 27 in the intermediate layer 5. As a result, a surface profile is formed for the armature component 22, with which a force transmission between the concrete layer 2 and the intermediate layer 5 is favored. In this case, the anchor member 22 would not extend into the concrete layer 3. The anchor component 22 has unidirectionally arranged boron-free silicate glass fibers with a polyester matrix. The cross-sectional view off Fig. 16 can be removed that the anchor member 22 has rounded corner portions 29.

A specific embodiment of an armature component 22 has the following external dimensions: Length 23: 13 cm Width 24: 4 cm Thickness 25: 8 mm

Finally, it should be particularly noted that the embodiments discussed above are merely for the purpose of describing the claimed teaching, but do not limit it to the exemplary embodiments.
