Description

The invention relates to a multilayer component comprising a first and a second shell, wherein the first and / or the second shell is formed as a textile concrete and comprises a textile reinforcement. The multilayer component is intended in particular for use as a semi-finished part made of textile concrete for wall and ceiling elements and for interior walls and ceilings with Ortbetonkern. The invention further relates to a method for producing the multilayer component and its use.

A multilayer component comprising an outer shell and an inner shell is formed in the prior art by both an inner wall element of the reinforced concrete double wall with two prefabricated shells functioning as a permanent formwork and an interposed Ortbetonkern as well as such an outer wall element, which by an additional Insulation layer is added.

The currently used outer shells of the reinforced concrete double wall are 5 to 8 cm thick to avoid reinforcement corrosion of the reinforcing steel. Mainly used as reinforcement structural steel. For exterior walls, stainless steel is also used less frequently to reduce thermal bridges. These components are produced on a highly efficient automated circulation system. The individual elements form through the Ortbetonkern a continuous wall plate with advantageous static properties.

The reinforced concrete walls have a very large component cross-section (d _min = 40 cm). This is uneconomical because the construction loses too much net area of the building. The large component cross-section results from the high demands on the protection of the reinforcing steel in external components and the ever-increasing demands with regard to the heat-insulating properties of the wall. By contrast, caused by the connecting elements made of steel, which connect the two elements of the reinforced concrete double wall with each other, significant thermal bridges in the wall construction.

However, textile concrete walls with a smaller wall thickness are also known from the prior art. However, these are currently not carrying or self-supporting and without further concreting, such. B. an in-situ concrete core executed. Moreover, the current solutions are not developed holistically as a building system. For example, only facade elements made of textile concrete are implemented.

Solutions for interior walls, ceilings and roofs with the corresponding systemic component couplings are not known.

Insofar as multilayer sandwich elements are used in the textile-reinforced concrete sector, these are only those without in-situ concrete core and heat-reduced anchors made of non-metallic materials. These elements are slim and have properties that reduce heat conduction. However, they are not load-bearing and are not manufactured and processed fully automatically.

In the prior art, various approaches are described to replace the traditional steel existing reinforcement by a textile. This is how the publication deals DE 100 19 824 A1 with a manufacturing process for building materials and components using fibrous materials, in particular natural fibers are used. The publication DE 102 32 142 A1 describes a method for the production of textile-reinforced concrete sheaths, as they can be used, for example, in the water and wastewater sector for the enclosure of plastic pipes or plastic containers.

From the publication DE 10 2004 027 739 A1 the description of a component in wood / concrete composite construction for construction, in particular columns, masts, columns, beams or pipelines can be seen. For an exemplary embodiment presented there, glass fiber cladding was used. After four textile layers a reinforcement layer of about 7 mm was reached.

The publication DE 10 2005 048 190 A1 provides information on the coating in reinforced composite materials, which can be used, for example, in fiber-reinforced high-performance concrete composites.

Through the pamphlets DE 10 2007 015 838 A1 and DE 10 2007 031 935 A1 The experts are experiencing a component with functional fibers and methods for its production. The publication DE 10 2007 038 931 B4 however, describes Fadenlagennähwirkstoffe and shows in one embodiment, the production of an open grid structure with the geometry of a truncated cone surface. These are Fadenlagennähwirkstoffe with contoured warp yarn, which are preferably used for the production of spatial reinforcement structures for plastic and concrete components. From one of these open lattice structures, for example, a 3D reinforcing structure in the form of a thread flank can be formed and introduced into the concrete of a pipe wall. The endless warp threads are in this Assembled in the lengths and supplied as required at the respective location to form the desired area.

However, all these solutions are not suitable for flat components, as they are regularly produced in a concrete plant. At least, however, they do not meet the requirements for permanent strength and temperature resistance of a reinforcement

Heating or general air conditioning devices for components are also known. These are based on electrical energy or a flow with a brine as a heat transfer medium. The previously available Elektroheizmatten or Elektroheizfolien are additive under z. B. floor or wall slips introduced. They are not embedded directly in a matrix. In addition, they only assume the function of heating. Additional functions, such as the combination of heating and carrying (reinforcement) are not yet available. As meander laid heating cables are previously laid on an additional carrier (eg., Support rail or plastic film). Thermoelectric components are used, for example, a Peltier element.

So far, a meander made of plastic pipes is inserted for the use of brine as a heat or brine in the reinforced concrete semi-finished with Ortbetonkern, the remaining available on the market surface heating systems such. B. underfloor heating in the screed, come very close. The conventional semi-finished parts with a thickness of 5 to 8 cm also allow the introduction of 1 to 2 cm thick pipes on an installation rail, which are laid at a distance of 10 to 20 cm. However, these pipes can not be integrated into a 2 to 3 cm thick textile concrete shell.

Object of the present invention is therefore to provide a structural component using textile concrete, concrete with a textile-based reinforcement. The goal is in particular to develop thin and slim wall elements, especially to achieve a slimming of the outer walls, which meet the increasing environmental requirements, especially for energy conservation, but are inexpensive to manufacture and lead to no further thickening of the building structures. All components for a building system and their component couplings should be provided. Another goal is the reduction of technical surfaces. In this context, optional functions of the building technology are to be integrated in order to save separate technical surfaces in the building. The aim is generally to reduce construction times, construction costs and building damage and to increase the usable area.

The object is achieved by a multilayer component comprising a first and a second shell, wherein the first and / or the second shell is formed as a textile concrete and comprises a textile reinforcement and is designed as a textile concrete. According to the invention it is provided that a semi-finished part is formed, wherein the first shell and the second shell are connected by a connection system in such a way and kept at a distance that a gap is formed: The gap can at least with in-situ concrete for producing a supporting , multi-layered wall to be filled.

It is thus a load-bearing, multi-layered wall is formed as a semi-finished part, the first and a second shell, in particular an inner shell and an outer shell, made of textile concrete. According to an advantageous embodiment, the semi-finished part can also be constructed in such a way that the first shell, for example the inner component, as a prefabricated reinforced concrete element and the second shell, for example the outer component, are designed as a textile precast concrete part. The gap can preferably be filled with in situ concrete on site to save on transport capacity and simplify installation.

A preferred embodiment is a hybrid wall consisting of two semi-finished parts. The inner component is a prefabricated reinforced concrete element and the outer component is a precast concrete element. In between are an insulating layer and a cavity, which is filled with in-situ concrete on the construction site. These shells are connected by a heat bridge reduced connecting means. This connecting means is punctiform in the region of the connection with the shells and consists for. B. of glass fiber reinforced plastic (GRP). The punctiform formation is achieved by tapered component ends, which also leads to the lowest possible visibility on the formwork side. Furthermore, the ends of the connecting element are provided with an additional broadening, as far as they are embedded in concrete, in order to ensure the best possible connection with the matrix material concrete. It is therefore advantageous if the connection system comprises a heat bridge reducing connection means.

An advantageous embodiment of the multilayer component provides that the intermediate space is filled with an insulating layer over at least part of its width, viewed transversely to the areal extent of the component.

The connection system of the component according to the invention is carried out according to an advantageous embodiment, thermal bridge reducing. Particularly preferably, it includes a thermal bridge-reducing spacer element or a total thermal bridge-reducing composite anchor. The connection system may also be punctiform to achieve the goal of reducing the heat transfer between the two shells.

In addition to the point-shaped connection system, which will be described in detail below, a linear connection system is alternatively provided. This has a higher mechanical stability, especially against shear loads. The punctiform and the linear acting composite anchors are arranged with respect to the mutually facing surfaces of the shells (20, 30) perpendicular or inclined from the vertical.

Insofar as the connection system comprises at least one composite anchor for the linear connection, this composite anchor is formed by a rail system made of fiber-reinforced plastic and / or planarly arranged bi- or rnultiaxialer Fadengelegen.

The composite anchors between the shells of the device according to the invention are incorporated in an intended depth in the. To increase the composite, the composite anchors comprise at least one end of a special shaping or structuring, which increases the pull-out resistance. The composite anchors are preferably already set automatically in a prefabrication of the textile reinforcement basket. Depending on the well-being of the insertion technology, the composite anchors receive plastic formations for securing the position of a yarn loop, which forms an end region of the composite anchor, or they are fixed to the textile structure of the reinforcement basket, preferably by means of adhesive.

In addition to the reinforcement introduced elements or even in the reinforcement integrated technical functions make it possible to dispense with separate technical device for these functions. The achievable functions affect heating and air conditioning, but also the function of an antenna or a shield.

According to a first advantageous development in this context, a meander of electrically conductive yarn is provided in areal extent in the first and / or the second shell. This can be placed next to a reinforcement also made of yarn or serving for reinforcement yarn is arranged in such a way that it can also fulfill the additional functions. In addition to the specific arrangement electrical connections are also required here, which protrude from the thus equipped component or otherwise accessible for later connection and connection with the relevant technical system.

In one application, this system is, for example, a heating or general air conditioning, which requires a connection for the supplied electrical energy. Then, the conductive yarn is arranged and electrically contacted so that it can be used for heat generation or, performed as a thermoelectric element, for cooling. Alternatively, the conductive yarn is arranged and electrically contacted so that it can be used as an antenna or as a shield against electromagnetic waves. With regard to the use of carbon fibers as a reinforcement, it has proved to be particularly advantageous if the electrically conductive yarn consists of carbon.

Wall heaters using capillary tube mats are known from the prior art. The capillary tube mats are usually according to the prior art directly on the wall z. B. perforated bricks fixed in the shell and subsequently plastered. The assembly is a purely manual process.

According to an advantageous development of the invention, in the first and / or the second shell, a capillary tube mat is introduced in areal extent with parallel or meandering, at least one capillary tube, in particular embedded in the concrete layer. The Kapillarroh is mono-, bi- or multiaxial arranged so that an area can be influenced

If the capillary tube is provided with a flow of heat through the capillary tube mat or the capillary tube with a heat transfer fluid, then usually for heating, or it is provided for heat absorption, then usually for cooling or for the production of heat. Heating or cooling of the shell and its surroundings, in particular of the space formed by the components according to the invention, takes place.

The functionalization of the finished parts is thus solved on the one hand by the introduction of a carbon meander for heating or by the introduction of capillary tube mats for heating and cooling of interiors. As a so-called massive absorber can be activated as a further advantageous application of the present invention in its previously described embodiment but on the other hand, the outer textile concrete slab by integrating a capillary tube for energy from an outer wall, for example, when exposed to solar radiation.

Another aspect of the invention relates to a method for producing a multilayer component for use as a semi-finished part as described above. According to the invention, a first shell is produced in a first concreting section, after which a second shell is produced in a second concreting section, wherein the second concreting section also comprises the connection of the first shell to the second shell, insofar as this is not already present through an integrated spacer element.

According to a particularly preferred embodiment of the manufacturing method according to the invention, the production takes place automatically on a precast circulation system. For this purpose, in the first concreting a composite anchor, but at least placed his anchor foot, for example, on a steel table, a first reinforcement, such as a textile reinforcement as it represents a Biaxialgelege is placed over it and then a spacer on the previously stored anchor foot, z. B. by screwing or snapping, mounted and formed the composite anchor. There are, if necessary, provided for setting concrete provided functional elements, including capillary tube mats, antennas or the like. Thereafter, the first shell is concreted and, if provided, an insulation placed on it.

This is done after curing of the concrete, which was introduced in the first concreting, a second concreting section. In the second concreting the second shell is concreted, a second reinforcement, preferably a textile reinforcement, z. B. a second Biaxialgelege, placed on the soft concrete. The already prepared in the first concreting first shell is turned around, so that their other flat side facing down to the second shell. By means of the projecting spacer elements, the second biaxial layer is pressed into the still soft concrete of the second shell. For this purpose, the spacer elements are preferably provided with a plate-shaped element. The position of the dish-shaped element on the spacer element determines the extent to which the second biaxial layer is pressed into the concrete of the second dish. In this case, the connection of the spacer elements can be done with screw anchors, which are carried out in the case advantageous in the interest of automated production to snap instead of the connection with a composite thread. However, dish-shaped elements which at the same time stabilize the reinforcement layer are preferred.

In automated production, the composite anchors or anchor feet are automatically placed on a steel table in the first concreting section. To fix them there, it has proven to be advantageous to equip them with permanent magnets. Alternatively, it is also possible to use a magnetic table which holds magnetizable composite anchors with magnetic force. The positions of the compound anchors or anchor feet thus define the exact location of the connection system. Thereafter, a reinforcement, preferably the Biaxialgelege, the first shell, z. B. the outer shell, placed on the composite anchors. Now, the snapping or screwing the corresponding spacer element, if advantageously only the anchor feet were stored. Finally, the concreting of the outer shell is carried out and optionally also an insulating layer inserted, as described above, which can also be done by machine.

In the second concreting section, according to the above description, the inner shell is first concreted in the automated variant, and then the biaxial layer is deposited on the fresh concrete matrix. Finally, the hardened outer shell is sucked in and rotated by 180 ° in order to place it on the fresh inner shell directly with the spacer elements. In this case, the Biaxialgelege is preferably pressed into the central position (by the spacer elements having plate-shaped elements at one end) and held by their buoyancy, which acts as a counter-force acting against the plate-shaped elements, stable there. The process is complete when the spacer elements reach the Schaltisch, preferably a steel table.

In the context of the manufacturing method described above, it is also provided that in the concrete of the first and / or second shell electrically conductive yarn, at least one capillary tube and / or at least one capillary tube mat is introduced.

For improved bonding of the yarn to the surrounding matrix material, the concrete, especially if this at least as load-bearing reinforcement is used, the yarn is provided with a sanded plastic coating.

A further aspect of the present invention is a use of the multilayer structural element as described above for structural wall and ceiling elements with in-situ concrete core. Also, entire interior walls and ceilings are offered and used in accordance with the present invention so that a complete building system can be offered.

The solution according to the invention is further directed to a connection system for a multilayer component as described above, comprising a first and a second shell. For the purposes of the present invention, in a heat-bridge-reduced connection system for connecting the first and the second shell, at least one composite anchor for concreting into the first shell is provided provided, wherein the composite anchor, provided for the positive connection with the concrete of the first shell, with a spacer element is connectable.

The connection system must fulfill several tasks: It must on the one hand connect both textile concrete shells as possible reduced thermal bridge, on the other hand, it must ensure sufficient anchoring in the thin textile concrete shell, also the connection system must be integrated into the automated circulation process of the concrete plant.

The connection system consists of at least two parts: an anchor foot and a spacer, designed for introduction into a first shell as described above, which form a composite anchor. For connection to a second shell, a plate-shaped element, in addition a screw anchor is provided, which is connectable to the spacer element on its side facing away from the composite anchor, in particular by screwing or by snapping.

The spacer element is designed according to an advantageous embodiment as a composite needle element and makes it possible to penetrate through the insulating layer. The spacer element also serves as a positional securing for the preferably centrally inserted Biaxialgelege.

Advantageously, the anchor foot of the composite anchor comprises permanent magnets, so that it can be stored and held on a steel table. Alternatively, a magnetic table may be used and an anchor foot of a magnetic material is held thereby. Both versions allow automated laying of the composite anchors or anchor feet. The spacer element is provided for the positive connection with the concrete of the second shell, optionally in addition with there inserted screw anchors, is preferably made of fiberglass and is also intended for connection to the composite anchor or its spacer element of the first shell. Additional grids ensure the composite safety when thrust forces occur between the textile concrete slabs. This can be replaced in your by the use of at least one composite anchor, which is intended for linear connection with the shells.

The textile concrete according to the invention, also referred to as a textile concrete double wall or hybrid double wall made of textile concrete (outer shell) and reinforced concrete (inner shell) with insulating material level, comprises an in-situ concrete core and an optional functional integration when used in the building. The preferred textile concrete double wall consists of two wall panels of textile-reinforced concrete with a minimum thickness of 2 cm and an insulating material (eg mineral wool or a high-performance insulation such as Slentide BASF), which is connected to a connection system, preferably in the context of the present invention.

The present invention combines the advantages of both variants: the industrially automated production as a load-bearing semi-finished part (with later-introduced in-situ concrete layer) with the forward-looking, space-saving non-structural textile concrete construction, supplemented by thermal bridge-reduced anchor elements for connecting the shells. The result is a building system for interior and exterior wall components, which meets the demands of the market to the highest degree, because it allows a wide variety of floor plan solutions to be implemented in the same system.

The innovation consists in the combination of the thin textile concrete shells, the innovative connection system as a connection of the two shells as well as fixing the position of the textile layers in the concrete slab with an optional insulating core and an in-situ concrete area inside. All this can be automated on a precast circulation plant. The finished individual components can be assembled on the construction site into a building system. Thus, complete structures can be realized in the present system. An alternative embodiment provides to assemble the bearing, multilayer wall according to the invention and to apply without introduced in-situ concrete.

The invention enables the realization of a very thin load-bearing exposed-concrete facade, which is produced automatically. Additional functions can be introduced very well into this system of automated production (eg component activation).

By using textile concrete with in-situ concrete core, the cross section of an entire wall structure can be reduced by 25% compared to a conventional reinforced concrete semi-finished part wall. In the case of an outer wall, this is supplemented only by an insulating layer. Thus, about 50% of the resources used can be saved in the production and transport of the finished part. The textile-reinforced finished parts are also more durable than outer wall elements than the conventional reinforced concrete prefabricated parts, since they have no reinforcement corrosion in the course of their service life even under extreme requirements or exposure classes. By novel, thermal conductivity reduced anchors or connection systems, both the reinforcement layers can be fixed in the textile concrete slab and the Dämmpaneele be connected without generating any significant point thermal bridges. These anchors can transfer the normal forces from the outer to the inner plate.

Particular advantages of the present invention are the combination of a thin textile concrete shell (outside) with a stable reinforced concrete shell (inside), preferably also with an integrated insulating layer, and the subsequent subsequent introduction of an in-situ concrete core on the site after installation on the building. Alternatively, the inner shell made of textile concrete. The prefabrication of the hybrid element from the thin textile concrete shell and the stable reinforced concrete shell can be automated on a precast circulation system. The finished individual components can be assembled on the construction site into a building system. Thus, complete structures can be realized in the present system.

The present invention can economically utilize the advantages of a reinforced concrete inner shell and connect it to a durable non-corrosive outer shell of textile concrete by means of an in-situ concrete core and an insulating layer. The additional functionalization of the concrete slabs enables the integration of building technology for heating and cooling.
