Textile concrete element

The invention relates to a textile concrete element, in particular as a facade element, in which at least one textile component is integrated into a concrete base material.

DE 39 01 937 A1 discloses a facade element of this type in a layered construction, which has at least two self-supporting layers and at least one insulating layer in between. The self-supporting layers consist of fiber-reinforced concrete. The fibers used can be single filaments, continuous yarns, strands, rods, as well as textile fabrics such as woven fabrics, knitted fabrics or fleeces.

The aim of fibre reinforcement in concrete is to increase the strength of the self-supporting layers. It also serves to increase weather resistance, heat and sound insulation and freedom from reflections of electromagnetic waves such as radar beams.

If short fibers are used as reinforcement in the self-supporting layers of the known facade elements, only a limited increase in load-bearing capacity can be achieved. The higher the strength is required, the more textile reinforcement must be introduced. This can also lead to an undesirable increase in the thickness of the building elements.

In addition, after the production of the outer layer, the so-called facing layer of the facade element, further work steps and means are required to give the concrete an aesthetic appearance and a high-quality surface. For example, additional plaster or other surface materials must be applied to the facade element. The resulting increased weight and dimensions of the facade element as well as the additional costs and time required to produce the facade element are disadvantageous.

The invention is based on the object of creating a generic textile concrete element in which a high level of strength can be achieved using simple means and which can be easily adapted to the properties of the respective intended use.

The object is achieved by a generic textile-reinforced concrete element with the characterizing features of claim 1.

With the help of the reinforcement layers, it is possible to strengthen the textile-reinforced concrete element in the long term, especially against tensile and bending stresses. Using a connecting element between the reinforcement layers, the reinforcement can be manufactured and installed in the desired manner at a distance from one another. This means that the reinforcement properties of the reinforcement layers can be fully utilized, as they can be arranged in a structurally favorable position. This also gives the textile-reinforced concrete element precisely its predetermined properties.

By positioning the reinforcement layers close to the surfaces of the textile-reinforced concrete element, the reinforcement layers are in the position in which the stresses and deformations are best absorbed when the textile-reinforced concrete element is subjected to bending stress. Furthermore, the associated spacing of the reinforcement layers from one another is beneficial for a defined position of the textile component when producing the textile-reinforced concrete element. The reinforcement layers can be positioned using simple means in a formwork used to produce the textile-reinforced concrete element.

Preferably, the textile component can be a three-dimensional structure that integrates the connecting means and the reinforcement layers. The three-dimensionally integrating design of the connecting means allows a spatial positioning of the reinforcement layers beyond a mere spacing. The integrating design of the connecting means also allows forces to be transferred between the reinforcement layers. In addition, the connecting means is customizable due to its three-dimensional design.

tes ensures a consistently high and defined quality of the textile-reinforced concrete elements to be produced.

In a particularly preferred embodiment, the textile component can be designed as a three-dimensional spacer fabric. This makes it possible to prefabricate the textile component with the connecting means in its three-dimensional extension quickly and inexpensively. With a textile fabric, forces can be introduced and released evenly, depending on the structure of the fabric in a constructively determinable manner.

The connecting means can be particularly advantageously formed using pile threads that determine the distance between the reinforcement layers, with the pile threads extending between the flat reinforcement layers. The point-by-point distance between the reinforcement layers can be determined using the pile threads. Furthermore, the type of pile threads and the number of pile threads used can be used to determine the force required to press the reinforcement layers together and the characteristics according to which a compressed textile component regains the desired spatial distance between the reinforcement layers.

According to a particular embodiment of the invention, the connecting means can consist of polyester and/or polyethylene and/or polyacrylsulphane and/or polyamide threads. Threads of this type can be processed into knitted fabrics, are inexpensive, flexible, sufficiently resistant to a concrete matrix and can withstand pressure and very high tensile loads. With the help of this type of thread, the original shape of a textile component can be recovered particularly advantageously.

The reinforcement layers can advantageously be flat textile fabrics with textile fibers and/or textile fiber bundles arranged approximately parallel to one another in at least one direction. This makes the textile concrete element particularly suitable for absorbing tensile stresses. The level of tensile stresses that can be absorbed in the direction of the fibers or in the direction of the textile fiber bundles can be determined by the type and number of textile fibers and/or textile fiber bundles in the relevant direction.

• ■* f

Depending on the directions in which textile fibers and/or textile fiber bundles are arranged in the reinforcement layers, tensile stresses in the respective fiber directions can be absorbed by the textile-reinforced concrete element.

As a variant of the invention, the textile fibers can consist of, preferably alkali-resistant, glass fibers and/or carbon fibers. By using resistant fibers, they are not attacked by the alkaline environment of the concrete and thus retain their mechanical properties. Glass fibers and carbon fibers can absorb particularly high tensile stresses.

Preferably, the textile fibers and/or the textile fiber bundles can be wrapped and/or coated. Coating protects the textile fibers and/or the textile fiber bundles from the effects of the alkaline environment of the concrete and also from the mechanically damaging effects of the crystal structures that form when the concrete sets. Wrapping the textile fibers and/or the textile fiber bundles also offers protection from mechanically damaging crystal structures that form when the concrete sets. Furthermore, the surface created by wrapping improves the bond between the textile fibers and/or the textile fiber bundles in the concrete.

As a variant of the invention, at least one further textile layer can be provided in the textile concrete element in addition to the reinforcement layers. The further textile layers can be used as additional reinforcement of the textile concrete element similar to the reinforcement layers. Their additional introduction to the reinforcement layers enables a modular design of the textile concrete element, in particular with regard to reinforcement levels and reinforcement directions. Depending on the requirements of the textile concrete element, the additional reinforcement layers can be introduced into the textile concrete element.

·

In a particularly preferred embodiment, the additional textile layer can be provided separately from the reinforcement layers and the connecting means. This allows additional textile layers to fulfil their function without affecting the reinforcement layers and vice versa. Furthermore, the separate arrangement of additional textile layers in the manufacturing process of the textile concrete element is particularly advantageous, since these only have to be placed next to the textile component in a formwork used to manufacture the textile concrete element. In this case, the textile component can also already be filled with concrete.

Particularly advantageously, the additional textile layer can be a flat textile structure with textile fibers and/or textile fiber bundles arranged approximately parallel to one another in at least one direction. This also results in the previously described advantages for this additional textile layer, which are associated with the use, number and arrangement of textile fibers and/or textile fiber bundles.

In a particularly preferred embodiment, the textile fibers can consist of, preferably alkali-resistant, glass fibers and/or carbon fibers. This also results in the previously described advantages of using alkali-resistant glass fibers and/or carbon fibers.

Advantageously, the textile fibers and/or textile fiber bundles can be wrapped and/or coated. The resulting advantages are also analogous to the previously described advantages of using wrapped and/or coated textile fibers and/or textile fiber bundles.

In a particularly preferred embodiment of the invention, the textile concrete element can have a fleece layer near at least one of its surfaces. By using a fleece layer, the textile concrete element gets a more aesthetically pleasing surface, which is particularly smooth, even and homogeneous. This leads to an expansion of the application area of textile concrete elements in areas that were previously reserved for elements made of natural stone or glass construction elements, for example. Furthermore, the reinforcement layers and any additional textile layers used are separated from the surface with the help of the fleece layers.

surface of the textile-reinforced concrete element so that the textile structure is not visible on the component surface. This simplifies the manufacturing process. In addition, sufficient concrete cover of the reinforcement layers and/or any additional textile layers used is ensured.

Preferably, the fleece introduced into the textile concrete element can contain a binding agent that dissolves when the concrete is filled. The fleece is introduced into the textile concrete element being created over a large area, preferably in one part. Due to the solubility of the binding agent, the fibers of the fleece dissolve and separate when the concrete is filled. The separated fibers create a homogeneous and smooth surface of the textile concrete element.

In a special embodiment, the binder can contain starch. Such a binder is particularly suitable for loosening and separating fibers when filling the concrete and the associated occurrence of moisture.

Advantageously, the reinforcement layers can be spaced apart from one another in a range of 1/5 to 9/10 of the wall thickness of the textile concrete element, preferably in a range of 2/3 to 9/10 of the wall thickness of the textile concrete element. The arrangement of the reinforcement layers close to the surface achieved in this way leads to a high degree of utilization of the textile reinforcement and is therefore particularly favorable. Furthermore, such a spacing is favorable with regard to the introduction of additional textile layers and/or fleece layers. A spacing of the reinforcement layers in the range of 1/5 to 9/10 of the wall thickness of the textile concrete element is advantageous. A spacing in the range of 2/3 to 9/10 of the wall thickness of the textile concrete element has proven to be particularly advantageous, whereby the integration of additional textile layers and fleece layers can be carried out particularly easily and in a particularly ideal range.

In the areas mentioned, it is possible to adjust the spacing of the reinforcement layers so that a particularly advantageous concrete cover of approximately

2 mm to the surface of the textile concrete element.

The concrete base material can be a fine concrete with a maximum grain size of up to about 3 mm, preferably up to a range of 1 to 2 mm. This ensures that the concrete matrix penetrates the textile component and any other layers inserted well during filling. Fine concrete also ensures smooth surfaces and sharp, clearly contoured edges.

In a preferred embodiment of the invention, the textile concrete element can have a wall thickness of up to 60 mm, preferably up to a range of 30 to 40 mm. This is a wall thickness that is sufficient for the load-bearing capacity of the textile concrete element. Furthermore, these wall thicknesses mean that the textile concrete element is comparatively light. This ensures that simple and conventional anchor systems can be used for fastening. Furthermore, a reduced overall wall thickness can be achieved with the help of such textile concrete elements, even and despite possibly thicker insulation layers.

According to a particular embodiment of the invention, facade elements can be designed with at least one textile concrete element according to at least one of claims 1 to 20. Facade elements designed in this way benefit from the advantages of the textile concrete elements according to the invention, in particular with regard to the high mechanical load-bearing capacity of the textile concrete elements according to the invention, their small dimensions and their low weight as well as their low manufacturing costs and their high-quality surface.

In a particularly preferred embodiment of the invention, the facade element can have a supporting layer, an insulating layer and a facing layer, wherein at least the facing layer has a textile concrete element according to one of claims 1 to 20. Such a construction enables the application of textile concrete elements according to the invention to conventional facade elements and reduces their dimensions due to the thinner facing layer according to the invention. When the thickness of the insulating layer is increased, the dimensions and the

Weight of the facade element in an advantageous range. Furthermore, standard fastening devices can be used in both cases. In addition, the facade element benefits from the advantages of the design of the textile concrete element used.

ft fr r ·

It is particularly advantageous to form an air layer between the insulation layer and the facing layer in the range of 1 to 50 mm, preferably in the range of 5 to 25 mm. This allows ventilation of the facing layer. This is particularly advantageous when the facing layer acts as a heat shield in the event of high levels of solar radiation and is therefore heated up very strongly. This creates a buffer between the facing layer and the insulation layer. An air layer is also advantageous for facades that are exposed to high levels of moisture or precipitation, so that moisture adhering to this facing layer or moisture absorbed by the facing layer is decoupled from the insulation layer.

Preferably, the facade element can be designed as a facade curtain element. This type of design also allows large facade elements to be prefabricated and buildings to be clad quickly, inexpensively and with high quality.

Embodiments of the invention are shown in the drawing and are explained below. They show:

and 10 fastening means of the facade process element of Figures 6 to

Figure 1 shows a textile concrete element 1 according to a first embodiment, in which a textile component 3 is integrated into a concrete base material 2. The concrete base material 2 consists of fine concrete with a maximum grain thickness of up to 1 to 2 mm, but no more than about 3 mm. The textile component 3 has two reinforcement layers 4, which are connected by means of a connecting means 5. In addition to the reinforcement layers 4, further textile layers 6 and fleece layers 7 are integrated on both sides of the textile component 3 in the textile concrete element 1. The textile layers 6, the fleece layers 7 and the textile component 3 are each arranged separately.

In this embodiment, the distance between the reinforcement layers 4 is only slightly smaller than the distance between two opposing surfaces of the textile concrete element 1. The distance between the reinforcement layers 4 can vary in a range from 1/5 to 9/10 of the wall thickness of the textile concrete element 1, preferably in a range from 2/3 to 9/10 of the wall thickness of the textile concrete element 1. This achieves in particular a concrete cover of approx. 2 mm to the surface of the textile concrete element 1.

Figure 1 also shows how the textile concrete element 1 is arranged between two formwork elements 8 during its manufacture. The formwork elements 8 are arranged in such a way that the thickness of the textile concrete element 1 is in a range of up to 60 mm, preferably in a range of between 30 and 40 mm. :****:

In Figure 2, the textile component 3 integrated into the textile concrete element 1, the textile layers 6, and the fleece layers 7 are shown in detail. The design of the textile component 3 as a spacer fabric is also indicated, whereby the spacer fabric has the two reinforcement layers 4 and the connecting means 5.

The two flat reinforcement layers 4 each have two layers of fiber bundles 9, with the fiber bundles 9 of one layer running parallel to one another. However, the direction of the fiber bundles of the two layers differs from one another. In a reinforcement layer 4, the fiber bundles 9 of the two layers are linked to one another. It can also be seen that the fiber bundles 9 in this embodiment are additionally covered by textile material 10.

In the present embodiment, the fibers in the fiber bundles 9 are alkali-resistant glass fibers. However, they can also be carbon fibers or a combination of both types of fiber. Fiber bundles 9 of different types of fiber can also be combined with one another.

Furthermore, the connecting means 5, which represents a three-dimensional structure and which connects the two reinforcement layers 4 in an integrated manner, is indicated. In this embodiment, the connecting means 5 consists of polyester, alternatively to polyethylene, polyacrylsulphane or polyamide, and has pile threads 11 which run approximately perpendicularly between the two reinforcement layers 4. The pile threads 11 determine the point-by-point distance between the reinforcement layers 4. In this embodiment, the reinforcement layers 4 are equally spaced apart, but they can also be spaced apart at different distances.

The textile layers 6 are flat textile structures and have several, in this embodiment two, differently oriented layers of parallel fiber bundles 12. The fiber bundles 12 of one layer are each linked to the fiber bundles 12 of the other layer by additional means, e.g. additional threads.

In this embodiment, the fibers of the bundles 12 of one layer are alkali-resistant glass fibers, and those of the other layer are carbon fibers. Combinations of different fiber types or of fiber bundles 12 of different fiber types can also be present. «...

Concerning both the reinforcement layers 4 and the other textile layers 6, the respective fibers can be wrapped and/or coated individually or the fiber bundles can be wrapped and/or coated as such. Furthermore, individual fibers and fiber bundles can be combined with one another. The fibers and fiber bundles can be the same or different.

In addition, Figure 2 shows the structure of the fleece layers 7, each of which consists of unoriented individual fibers 13 that are held together with a starchy binding agent that dissolves when the concrete is filled. The fleece layers 7 are arranged close to the surface in the textile concrete element.

Figure 3 shows a facade element 14 which has a facing layer 15 consisting of a textile concrete element according to the invention, an insulating layer 16 and a supporting layer 17. The supporting layer 17 has a concrete steel reinforcement 18. The facing layer 15, the insulating layer 16 and the supporting layer 17 are connected to one another with the aid of bonding agents 19.

Further facade elements according to a third and fourth embodiment are shown in Figures 4 and 5. These also have a supporting layer 20 made of reinforced concrete and an insulating layer 21. In analogy to the facade element shown in Figure 3, the facade element of the fourth embodiment shown in Figure 5 also has a facing layer 22 made of a textile concrete element according to the invention. The facade element of the third embodiment shown in Figure 4

Embodiment has a facing layer 22 in the form of separate facade panels 23, which is arranged at a distance from the insulation layer 21 by an air layer 24. The air layer 24 can have a thickness of 1 to 50 mm, preferably 5 to 25 mm.

Figures 6, 7 and 8 show a facade curtain element 25 from different perspectives. Figure 6 shows the side view, Figure 7 the front view and Figure 8 the top view of the facade element. The facade curtain element 25 consists of a multi-slotted plate made of a textile concrete element according to the invention and side and rear integrally formed wall reinforcements.

The façade process element 25 is fastened by means of fastening means indicated in Figures 9 and 10.

In a horizontal section, Figure 9 shows two facade curtain elements, each of which is fastened to suspension elements 28 by means of first screw means 27. The suspension elements 28 are suspended in a cross element 29 which is held by a support element 30. The support element 30 is fastened to a wall 32 by means of bolts 31.

Figure 10 shows the fastening means from Figure 9 in a vertical section. Here it can be seen in particular how the suspension elements 28 engage with the cross elements 29.

In the following, the effect and functioning of the embodiments of the invention shown in the figures are explained.

The concrete base material 2 of the textile concrete element 1 according to the invention shown in Figure 1 can be subjected to a high degree of compression, but only to a comparatively low degree of tension. However, so that the textile concrete element 1 can also absorb a high degree of tensile stress, the concrete base material 2 is coated with a textile component 3 and further textile layers 6.

The fiber bundles 9 of the reinforcement layers 4 of the textile component 3 can absorb a high degree of tensile stress in their longitudinal direction, while only stretching very slightly. The situation is similar with the fiber bundles 12 of the upper . ·,

Textile layers 6 arranged halfway and below the textile component 3. * **

• The extent of the tensile forces that the respective fiber bundles 9, 12 can absorb in their longitudinal direction depends on the nature of the fibers of the fiber bundles 9, 12 : ·*;. It is conceivable that different fiber materials are used in the various layers of the reinforcement layers 4 and the textile layers 6.

For example, alkali-resistant glass fiber bundles can be used in one layer, and in another layer with a different direction of the fiber bundles, for example carbon fibers. It is also possible to combine different types of fibers in the individual fiber bundles 9, 12 and/or to arrange individual fibers in a layer in addition to the fiber bundles 9, 12 in the same direction as the fiber bundles 9, 12 in order to adapt the properties of the textile-reinforced concrete element 1 to the requirements.

The reinforcement layers 4 and the textile layers 6 are each arranged very close to the surface of the textile concrete element 1. In the directions in which the fibers and/or fiber bundles 9, 12 of the reinforcement layers 4 and the textile layers 6 run, the textile concrete element 1 can absorb tensile stresses and tensile stresses arising as a result of bending stresses. Depending on the expected stresses on the textile concrete element 1, it can therefore be designed in a targeted manner.

Furthermore, forces can also be transferred between opposing reinforcement layers 4 of the textile component 3 using the connecting means 5 of the textile component 3 shown in Figure 2. This is possible in particular due to the structure of the integral spacer fabric, whereby the structure of the spacer fabric enables forces to be introduced well and evenly.

In addition, the structure of the connecting element 5 determines the spacing of the reinforcement layers 4. In particular, the vertical

Components of the connecting means 5 play a decisive role. Their length determines the distance between the reinforcement layers 4. Their elastic behavior determines the restoration of the spacing of the reinforcement layers 4 after the textile component 3 is compressed before it is introduced into the textile-reinforced concrete element.

Prefabricated textile components 3 can be used in the manufacture of textile concrete elements 1 according to the invention. The textile component 3 can be manufactured in one operation and is delivered on rolls. The textile component is compressed on these rolls, i.e. the distance between the reinforcement layers 4 shown in Figures 1 and 2 has been compressed. After the textile component 3 has been unrolled and thus after the compressive forces have been removed, the reinforcement layers 4 are brought into their intended position and distance from one another due to the structure and properties of the connecting element 5.

The textile component 3 can then be impregnated with fine concrete on a conventional formwork table. The textile layers 6 and the fleece layers 7 can be inserted into the formwork 8 together with the textile component 3. If the textile component 3, the textile layers 6 and the fleece layers 7 are already delivered in the correct order on top of each other, the insertion can take place in one step. The fleece acts as a spacer between the textile layers 6 and the textile component 3 and the surface of the textile concrete element 1 being created.

During the concreting process, the spacer fabric remains dimensionally stable.

On the later surface of the textile element 1, the fibres of the fleece layers 7 are released and separated by contact with the water of the poured concrete. In this way, a homogeneous surface of the textile concrete element 1 is created and sufficient concrete covering of the textile reinforcement is achieved so that it does not show through. The position of the fleece layers 7 and

The textile layers are secured during the concreting process by the connecting element 5 of the textile component.

In the facade element 14 shown in Figure 3, with the help of an inventive *. *".,

A facing layer 15 is implemented on the textile-reinforced concrete element 1 according to the invention. Due to the textile reinforcement of the textile-reinforced concrete element 1, the facing layer 15 can be made very thin, since only a very small concrete cover is required for the textile-reinforced concrete element. This allows the entire thickness of the facade element to be used.

mentes 14 can be reduced or, while maintaining an acceptable thickness of the «...

facade element 14, the thickness of the insulation layer 16 can be increased. \' ·,

Furthermore, the facing layer 15 has a low weight compared to conventional materials due to the low thickness of the textile concrete element 1.

The production of the facade element 14 follows the described production of the textile concrete element 1. After the textile component 3 and any integrated textile layers 6 and fleece layers 7 have been impregnated, the bonding agents 19 are placed in the still wet concrete. The insulation layer 16 is then applied and the supporting layer 17 made of reinforced concrete is poured on top.

In the facade elements shown in Figures 4 and 5, textile concrete elements 1 according to the invention are used as a facing layer 22. The facade element shown in Figure 4 has the facing layer 22 in the form of facade panels 23.

The facade curtain element 25 shown in Figures 6 to 8 has a lower weight compared to conventional facade curtain elements and thus allows the use of conventional fastening means as shown in Figure 9 as a horizontal section and in Figure 10 as a vertical section.

·

By using fine concrete as the concrete base material 2, smooth surfaces and sharp-edged profiles and joints can be realized. This leads to a new appearance of the concrete surface of textile-reinforced concrete elements according to the invention.
