Abstract

A walling element is characterised by components (2) which consist of concrete, are annular in cross-section, perform mainly static constructional functions, have on the outside the form of a regular hexagon, surround a cylindrical hollow space (4) and are interconnected homogeneously in terms of their material by their side faces (7), fillers of a geopolymer foam material being introduced into the hollow spaces (4), at least some of the said fillers having centrally arranged, cross-sectionally circular clearances (12). The clearances (12) may be glazed, so that a walling element constructed from these modular parts satisfies heat-insulating and soundproofing functions on the basis of the said fillers and can be used for controlling light conditions on the basis of the clearances, to be precise equally in walling applications and in ceiling or else roof construction applications. The clearances (12) are, if need be, bondable homogeneously in terms of material by introducing structural elements which are appropriately shaped and have appropriate material properties and by using a geopolymer material of an unfoamed formulation, with the result that on site there is a high degree of flexibility in the use of these walling elements which are constructed from just a few modular parts and consist completely of inorganic materials, meaning that fire prevention requirements are also adequately taken into account. <IMAGE>

Description

The invention relates to a wall element according to the preamble of claim 1.

The introduced in the course of the rationalization of building construction industrial prefabrication of complete walls As is well known, elements has the disadvantage that subsequent Changes to the building fabric or in the course of the wall are often hardly feasible with reasonable effort. This construction is also relatively high Planning effort connected. Particular problems arise also in the event of changes, in particular expansion measures took part in existing installation facilities, e.g. B. Pipelines of supply and disposal, which are often called Result from a changed use of space.

The classic design is characterized by a juxtaposition of structural elements such as B. a  Masonry, heat-insulating functional elements, e.g. B. thermal insulation panels from an organic foam fabric and installation facilities such as piping featured. From the material inhomogeneity of the first two functional elements result Differences in aging and wear behavior, the thermal insulation materials mentioned risk in the event of fire represent sources, as these at elevated temperatures can either maintain a fire yourself or in Release toxic carbonization gases in individual cases. Overall, this design is also due to the variety of manual associated with assembly Activities, but also due to the special construction precautions in the sense of a preventive fire protection extremely expensive.

Numerous components used in building construction from pourable, in the initial state or under heat effect plastically deformable masses produced. It these can be inorganic masses on cement base or other hydraulic binder or act as ceramic masses. A special one advantageous material that can be used in construction seen in the group of geopolymer materials which in numerous modifications, e.g. B. foamed and unsung can be used in foams and especially in non-foams state essentially ceramic properties Have materials, but the latter for the latter Material group plant and energy intensive Brennpro zeß does not apply because these materials in one form Harden temperatures below 100 ° C.

The geopolymer materials are known, for example from DE 32 29 339 C2, DE 33 03 409 C2 or from "Ceramic Matrix for Composites" (Ceram. Eng. Sci. Proc.  Pages 835 to 841). These consist in the starting medium creation from a solid mixture of oxides with content ten of amrophic SiO₂ and aluminum oxide in combination with a water-containing amorphous, dispersed powder against silica and fillers such. B. heavy spar, Zircon sand, mica, waste from molten bauxite, ba salt flour, quartz, feldspar, granite quarry etc. and one aqueous potassium potassium potassium silicate solution. From These components existing mass can be in a form be introduced and harden in this. Under one Foaming agent can do this in this way manufactured part also formed as a foam part become.

It is the object of the invention, a wall element of the type described at the outset with regard to its To design usability in building construction, in particular especially considering a simple montier availability and flexible handling on site. This task is solved with such a wall element by the features of the characterizing part of claim 1.

According to the invention, ring-like, construction stati are essential Functional components, the material are selected with regard to this function, which are inorganic materials. These Components form the support structure of a wall element, its further use by the type of in the, of the Components enclosed cavities introduced filler is determined by or filling masses. With these fillers As with the components, it can be industrial act prefabricated parts - the packing can but also by on-site in pourable form in the masses introduced are formed.  

These ring-like components are within the Wall element in connection with each other, which in can happen in many ways, for example by Screw connection in the case of detachable connections or through Gluing in the case of permanent connections. Preferential as is done so that the total structure of the statically acting components as material homogeneous system.

The features of claim 2 are based on a first congress tization of the wall element directed. According to this the components are interconnected on the face side, for example in adhesive connection, so that through these bounded cavities are aligned with each other are net and emerge from the front side one behind the other arrangement of the components each column-like assembly surrender. The wall element is from these assemblies built up, which are laterally connected to each other hen, for example and preferably homogeneous with are glued to each other. A sol ches wall element as a partition, as an outer wall, however also in the context of floor, ceiling and roof construction NEN, the filling bodies penetrating the cavities or filling compounds according to the expected stati loads are selected differently can. The modules can be part of a Partition or outer wall vertically, but also horizontally or at any angle to the horizontal plane stretch.

The features of claims 3 and 4 are on a Varian te of the wall element directed. The wall element hereafter consists of at least one wall shell, which is composed of the components mentioned, the however, he is in the plane of this wall shell  stretch, d. H. through their side parts with each other Connect. In the simplest case, there is a wall element from a single wall shell, whose thickness through the - perpendicular to the plane of the ringar term components - thickness of these components determined is, the cavity enclosed by the components me are filled with packing. On the outside it can wall element formed in this way in any Way, e.g. B. coated for decorative purposes. It it is also possible to use two or more layers Build up wall elements, their individual wall shells are identical to each other. The individual wan Extension shells are in a suitable manner interconnected to the cohesion of the wan to ensure element. By arranging more shelled wall elements can turn the building physics calic properties of the wall element in simple be varied in a manner such. B. their static carrying capacity ability, but also heat and sound insulation speed. Basically, in the context of a wall shell also column-like assemblies of the type described above Find use.

The components exist according to the characteristics of Claim 5 from a concrete or a geopolymer Material, the latter in preferably non-foamed Execution. According to the static to be recorded In principle, however, foams also come under stress Geopolymer materials. Both the concrete and the geopolymer material can also be used if necessary be equipped with suitable reinforcement elements.

The features of claims 6 to 9 are different Liche geometric embodiments of the, structural Functional components directed. Vary  can the internal cross-section, but also that Outer profile. Inner and outer profile can be related to each other be geometrically similar - but are considered also different geometric shapes. Preferably it is particularly the outer profile geometrically simple shapes, namely those that are too put together a seamless, extensive system let, e.g. B. regular hexagons.

The features of claim 10 are based on a variant of Embodiment of the wall element directed in which the Components assembled into columnar assemblies are. The given in such an assembly sequence of components made of concrete and those made of one Geopolymer material, the latter optionally in ge foamed shape, but according to one that requires density taking static load-bearing capacity into account, gives a particularly easy way to a body sound transmission in the direction of the columnar assembly to effectively prevent pen. At the same time, this can Way the mass of the wall element kept within limits be a point of view, especially when it comes to measures renovation of old buildings is of the greatest importance and special construction measures to the otherwise necessary Increase the static load-bearing capacity of the building structure superfluous.

The features of claims 11 and 12 are on the fro position of an outside smooth, especially flat Surface having wall element directed, and in spite of the polygonal, especially hexagonal, or circular cross-sectional shape of the individual NEN components. According to this, fillers are provided which are designed geometrically such that the two ver the outer boundary surfaces of the components  permanent spaces for the formation of flat surfaces on the outside be completed. In terms of materials, they can Packing in turn to improve the static Load capacity, but also to improve the heat and Sound insulation behavior can be used. It can accordingly, this packing made of concrete, for. B. bausei but also prefabricated in-situ concrete Concrete parts exist. Similarly, these can fill but also made of a geopolymer foam material exist and in any case armored or unarmed Find use. More variation options exist with regard to the attachment of the packing the components, which are detachable, e.g. B. in the manner of a ver screw connection, but also unsolvable, namely by Stoffho mogeneous bonding can be achieved.

The features of claim 13 simply open up reali further architectural design options that can be designed ten trained with the help of the invention Wall elements. So, those assigned to the components Filler with recesses, either open design or using glazing transparent or at least translucent could be. In the case of open training, there is Possibility of making walls extremely air-permeable according to the size of this recess This can be for air conditioning reasons, however ventilation should also be useful. In the event of it is possible to glaze these recesses speed, such wall elements to influence the To use lighting conditions of rooms, whereby the Wan elements either in the context of external or separation walls or in the context of roof or ceiling construction applications. The one used for the packing Geopolymer material opens up particularly simple here  Possibilities to vary the lighting conditions, and through the subsequent introduction of further recesses gene in other packing or by subsequent closing such recesses. This can be done under Use of this material on site in particular simple way through homogeneous bonding of a material insert with the edges this recess. These exceptions can also gene be closed on one side and at for example in an even distribution over a full permanent room wall can be provided. You can click on this Make a room acoustic contribution in the sense of a Reduced reflection and thus noise insulation most. These recesses can also be used for accommodation be used by lighting fixtures.

The features of claims 14 to 16 are in one Particularly easy to implement form of assembly technology linking two wall shells directed. This is based on a screw connection that over Clamping body is guided in, for example, conical Recesses are used, the taper of both Outside of the wall element in the direction of a Is directed towards the middle plane, d. H. that the exception taper in this direction. With respect This principle can also be triple and multi-layered Wall elements are built. Then use them the screw connections of two, each other in the outside opposite wall shells then penetrate all of the three or more walls elements. Instead of screwing are natural however, the wall elements can also be glued, which in turn are preferably made homogeneous are.  

In the case of multi-layer wall elements, the individual wall elements also from thermal insulation layers organic foam plastics are provided. This seems acceptable because of this organic wall application part is integrated on both sides in inorganic parts and is therefore protected even at elevated temperatures. Another case can be reached in this way contributes to the improvement of the heat and sound insulation behavior tens.

The features of claims 18 and 19 are further Embodiments of the wall element directed, in particular with multi-layer design. After that, the one individual bowls also serve different purposes and in particular also be designed differently. So is, for example, the arrangement of one for absorption impinging heat radiation serving wall shell possible, which is an integral part of a Rohrlei tion network includes, which in the respective outside the wall shell is provided distributed over the area and one with one or more heat consumers closed circuit for a heat transfer medium bil det. After the geopolymer materials were widely used properties of ceramic materials, there are also numerous opportunities for outside sided coating, for example to decorative Purposes. However, at any time due to the simple machining options, e.g. B. by milling, Drilling, sawing or the like subsequent changes be made. It can be seen from the above explanations that the wall element according to the invention from a few The main part of the module consists only of the called ring-like components, whereby by their spatial arrangement in connection with the type and The nature of the packing and their function in the frame  a building structure is first determined.

The invention will now be described with reference to FIG the embodiment shown in the drawings games are explained in more detail. Show it

Fig. 8 is a view of another embodiment of a wall element;

FIG. 9 shows a cross section of a wall element according to FIG. 8 according to a section plane IX-IX.

The essential feature of the Wandele element shown in FIGS . 1 and 2 is a juxtaposition of columnar assemblies 1 which extend in the plane of the wall element. Each of these assemblies consists of an arrangement, extending in the axial direction thereof, of ring-like, face-to-face contact, with the shape of a regular hexagon having components 2 on the outside. The components 2, which are dimensioned the same as one another, alternately consist of concrete or a geopolymer material, which can be foamed or non-foamed. The latter depends, among other things, on the required static load-bearing capacity of the wall element. The components 2 of an assembly are end-to-end homogeneous, that is to say preferably glued to one another using a non-foamed geopolymer material.

Each component 2 encloses a cross-section cylindrical cylinder-like passage 3 , so that due to the aligned arrangement of the components 2, each assembly 1 encloses a circular-cylindrical cavity 4 .

5 denotes an opposite corner point of the outside cross-sectional profile of a component 2 including the plane of symmetry, which extends perpendicular to the plane 6 of the wall element. The components 2 of each assembly are thus on their side faces 7 with other assemblies in connection, this connection is preferably based on a bond, for example using an unfoamed geopolymer material. In principle, however, another suitable material similar to the materials of the components 2 can be used as an adhesive, so that the wall structure is as homogeneous as possible.

Due to this arrangement of the individual modules 1 a regular Anord arises relative to the plane 6 voltage of recesses 8, which extend in the longitudinal direction of the individual modules 1 and the shape of isosceles triangles each having in cross-section.

Such an arrangement naturally occurs on both sides of the wall element, but is shown on only one side for reasons of clarity in the drawing. These recesses 8 are in turn filled with a geopolymer foam material in order to form an outside flat wall structure in FIG. 1, the resulting outside in plane 6 - or inside of the wall element - can be coated in any way, for example with purely architectural acting components.

In the same way, namely with a geopolymer foam material, the cavity 4 is filled.

The fillings of the recesses 8 can be industrially prefabricated on the basis of the known geometric conditions and, for example, can only be glued on-site to the facing surfaces of the modules 1 .

However, a screw connection can also be considered, for example in order to maintain the accessibility of the assemblies 1 .

By varying the density of the geopolymer foam materials used in the recesses 8 and the cavities 4 of a wall element, the thermal and acoustic insulation capacity and equally their static load-bearing capacity can be varied within wide limits. If necessary, the fillings of the recesses 8 and / or those of the cavities 4 can additionally be equipped with suitable reinforcing elements.

Due to the alternating arrangement of components 2 made of concrete and those made of a geopolymer material, speed of the wall element is furthermore contributed to the improved thermal and acoustic insulation capacity, and in the same way within the same plane. A structure-borne noise transmission in the plane of the wall element, in the direction parallel to the modules 1 can be effectively countered in this way.

The wall element shown in Fig. 1 has flat surfaces on both opposite sides 9 and 10 , so that the recesses 8 are filled in the same way on both sides. This Wandele element can be used equally as a partition, as an outer wall, but also as the floor of a building.

Finally, the wall element shown in FIG. 1 can be modified to improve its static properties - as shown in FIG. 2 - in such a way that the recesses 8 are filled with concrete or concrete components, the concrete being reinforced. In this way, the wall element is particularly suitable for absorbing tensile forces which act in the longitudinal direction of the individual modules 1 and can be used, for example, as a ceiling element. Instead of the alternating arrangement of components 2 made of concrete and those made of a geopolymer material, an assembly 1 can also consist entirely of components made of concrete, so that the heat and sound insulation ability of the wall element essentially by filling the cavities 4 individual modules 1 is determined.

Columns 2 can also be produced directly from components 2 of the type shown in FIGS. 1 and 2, the filling of the cavities 4 again being designed in accordance with the static load to be expected. For example, these cavities 4 can also be filled with concrete, in reinforced or non-reinforced form, and the outside of components 2 can also be coated in any manner.

The embodiment shown in FIGS. 3 and 4 of a wall element differs from that of FIGS. 1 and 2 essentially in that the components le 2 now extend perpendicular to the plane of a wall element and over all of their side surfaces - with the interposition of one not graphically Darge presented, preferably made of the material of the components 2 adhesive to each other. The components 2 form in this case the support structure of the wall element, which gives this the required static strength.

The cavities 4 of the individual components 2 are partially filled with a geopolymer foam material, but in the central area there is a square recess 11 , which can be open throughout, but which can also be designed like a window, ie for receiving serves a glazing.

FIG. 4 shows a modification of the wall element according to FIG. 3 insofar as only a part of the components 2 is provided with central recesses 12 , which are used in the same way as the recesses 11 , here only have a circular shape.

Wall elements of the type shown in FIGS. 3 and 4 can be used in various ways as room partitions, for example for setting certain Hel conditions. They can be used in particular as ceilings or roof elements to provide daylight to the room below. For this purpose, the recesses 11 , 12 can in principle be of any geometric shape. Finally, these wall elements, in particular the recesses 11 , 12, can also be closed on an end face of the components 2 , for example by means of plate-like components which preferably correspond to the material used for filling the cavities 4 and are glued homogeneously to this filling.

In the embodiment according to FIGS. 3 and 4, it has been assumed that a Wandele element is constructed by side-by-side attachment of several components 2 . All components 2 are thus essentially arranged in one plane.

As shown in FIGS. 5 and 6 show, however, there is also the possibility of the components 2 in several, here to arrange two levels, thereby to form a plurality Wandungsschalen and these Wandungsschalen to verbin to each other.

The components 13 of a wall shell are in turn connected to one another via their side surfaces 14 with the interposition of a suitable adhesive layer, preferably of the same material, which is not shown in the drawing. In deviation from the exporting corresponding to 1 approximately examples FIGS. To 4 are the components 13 of a shell of the wall element shipping hen at one of their six corners with recesses which, starting from one side 15 of a shell has a conically in the direction of a plane of separation 16 have a tapered design between the shells. In the illustrated embodiment, the limita- tion surfaces of these recesses 10 are formed by parts of cylindrical surfaces whose axes extend under angles to the plane of the shells of the wall elements. It is the wall element with respect to the central plane 16 constructed symmetrically, so that the Ausneh lines 17 'of the other shell from the opposite side 18 in turn taper towards the central plane 16 .

In these recesses 17 , 17 'each clamping body 19 are used, the shape of these recesses 17 , 17 ' are adapted and using Verschraubun gene 20 , which are only symbolically indicated in the drawing and by two, mutually symmetrical on both sides of Center plane 16 extending clamping body 19 are passed. The clamping bodies 19 are expediently arranged flush with the outer sides of the wall element and the screw connections can be arranged sunk in these surfaces. It can be seen that the two wall elements forming the wall elements are thus held together via the screw connections 20 .

This principle can also be expanded in that wall elements can be constructed from more than two wall shells so that an intermediate shell extends between the two wall shells shown in FIG. 6, which in turn is constructed similarly to the wall shells shown, the recesses of which, however, are cylindrical are trained drisch.

The resulting in the area of the top and bottom of such a wall element due to the circumferential design of the components 13 , the cross-sectional shape of equilateral triangles having recesses are filled with fillers 21 , by means of which top and bottom with respect to the wall element flat end surfaces result. It can be Füllkör by 21 , which are integrally formed and extend through the recesses of both wall shells of the wall element. The filler 21 can, however, also be dimensioned in such a way that they only penetrate a wall pan visibly of their dimensions, which extend perpendicular to the plane of FIG. 5. They are in the latter case via screw connections 22 with each other so that the cohesion of the wall shells of the wall element is also ensured in this way. For this reason, the boundary surfaces of the filler 21 in the same way as those of the clamping body 19 bezüg Lich the central plane 16 have a symmetrical, tapered course.

In the game shown in FIGS. 5 and 6, the filler 21 are formed of concrete. However, they can equally well be made of a geopolymer material, namely foamed or non-foamed, armored or non-armored. A wall element shown in these figures can be used, for example, as a parapet wall for balconies, as a general wall element in building construction and in particular in all applications in which a wall element that can be used in a simple manner with regard to its physical properties in particular can be used as a partition or as a half-height wall is needed.

The wall element according to FIGS. 5 and 6 can be varied in a variety of ways, specifically using construction features which have already been explained with reference to FIGS. 3 and 4. For example, some or all of the components 13 can be provided with centrally arranged recesses 23 in such a way that the recesses 23 of both or all of the wall shells of the wall elements are mutually identical and arranged in alignment with one another. In this way, the wall element can be designed to be translucent to a degree determined by the number and size of the recesses 23 , which can be used with advantage not only when used as a room wall, but also as a component in the context of ceilings or roofs.

FIGS. 8 and 9 show a further variant of the Substituted staltung a wall element, wherein components 2 accordingly find the position shown in Fig. 1 type use. These components are put together to form a single-shell wall with their side surfaces 7 , so that all components 2 extend in the plane of the element. The components are in turn connected in the manner already described above.

With 24 a foundation part is designated, the upper profile 25 is determined and designed to produce with the facing sides side by side arranged components 2 a positive connection. The foundation part 24 consists of concrete, possibly in a reinforced form and is itself in a manner not shown in the drawing with a floor construction in connection. The connection between the foundation part 24 and the components 2 takes place with the interposition of a suitable adhesive layer which corresponds to that which already exists between the components 2 .

In the cavities 4 of the individual components 2 are on receiving body 26 are used, which consist of a geopolymer foam material and in its central region, a tapered recess 27 from one side of the receiving body to the other side thereof. The receiving body 26 has a thickness which essentially corresponds to that of the component 2 and the recess 27 can have the shape of a rotational hyboloid.

With 28 plates made of a geopolymer foam material are designated, the interposition of a layer 29 of an organic foam material, for. B. polyurethane with the, in the rest of the juxtaposition of components 2 existing wall element in hen hen. The plates 28 can be of a purely decorative type and can be equipped, for example, in one piece with vessels for receiving plantings. However, these plates 28 can also be provided with integrated pipes 30 , in which a heat transfer medium is guided in the context of a circuit (not shown in the drawing), so that this side of the wall element can be used to absorb incident heat radiation.

In the latter case, the plates 28 and in particular the tubular elements 30 are formed from a non-foamed geopolymer material in order to improve the thermal conductivity and to achieve the most effective possible transfer of absorbed heat radiation to the heat transfer medium. In this case, the tubular elements 30 form an area-wide network covering the wall element, which network may include one or more heat consumers, heat stores or the like. The best of an organic foam material existing layer 29 ensures a very extensive heat insulation, so that heat transfer perpendicular to the plane of the wall element and thus to the plane of the layer 29 is prevented and the absorbed heat is dissipated exclusively via the heat transfer medium.

The side of the wall element produced in this way, which has recesses 27 , has a considerable sound insulation capacity, owing to the effect of the recesses 27 in connection with that of the layer 29 consisting of organic foam material. At the same time, the wall element on the side opposite the recesses 27 can also have a particularly decorative surface design.

As an alternative to the embodiment shown in FIG. 9, the components 2 with the insert bodies 26 used can also be used in the context of a single-walled wall element, the recesses being able to influence the lighting conditions and in the context of partition walls, outer walls or ceilings are usable.

It can be seen from the above statements that component 2 according to the invention can be used by the customer as a module in numerous modifications, in accordance with the structural function required in each case. It can also be seen that functions of installation technology, air conditioning technology, in particular the production of solar energy and also lighting technology can be integrated in a simple manner in a wall element produced in this way. Each of the wall elements described consists essentially of the components mentioned, for. B. in single or multi-shell form, which mainly fulfill the functions of statics, with the spatial arrangement of the components and the attachment and the nature of their fillings, the properties of the wall elements formed in this way vary widely and in each case Have the actual application adapted. To fill these components, but also for coating, a geopolymer material is used in wesent union, namely foamed or non-foamed, so that the wall element formed in this way consists entirely of inorganic materials and there is no danger of this in the event of a fire .

The geopolymer material is also of particular advantage This is because, in the event of subsequent changes, the in openings partially present in the receiving bodies or can also be completely closed again, namely by suitable components of the same material are glued in or by adding further openings by sawing, Milling or drilling are provided. A Industrial prefabrication is with these wall elements thus only given to the extent that this results in the on-site Flexibility is not hindered.
