Description

The present invention relates to a method for producing a component with at least one conductor arrangement, in particular the production of concrete components with translucent fibers. Furthermore, the present invention relates to a device which is produced by a corresponding method. Such components are used in particular in the manufacture of buildings, walls and / or facades.

Methods are known in which such components are made of concrete, wherein the conductor arrangement with the light-conducting materials are first placed in a die and then cast with concrete. In this way, although relatively simple plate-shaped components can be produced, however, the freedom of design with regard to the components produced is limited in this type of production. In addition, this method can not always be guaranteed that all areas of the component can be brought into uniform contact with the concrete, so that under certain circumstances, inhomogeneities with regard to the properties of the component after production can occur.

From the DE 10 2006 007 920 B3 For example, a process is known in which fibers are unrolled from a roll and incorporated in a mortar sled into a hydraulically setting mass. Subsequently, the hydraulically setting compound and the fibers are filled by the mortar carriage in a formwork consisting of a frame and a vertically movable floor. In this case, the movable floor is set to a height below a Schalungsoberkannte, which corresponds to the height of a layer of hydraulically setting mass and fibers. As soon as the formwork is filled to the upper edge with hydraulically setting mass and fibers, the bottom of the formwork is lowered by a height corresponding to the height of a layer of hydraulically setting mass and fibers, and the formwork again up to the upper edge with hydraulically setting mass and Filled with fibers. This is repeated until a desired height of a shaped block is reached.

At one of the DE 20 2007 000 753 U1 known methods are peeled off tissue from a roll and placed in a formwork tool in which a thin concrete layer is present. Subsequently, the fabric is covered with a thin concrete layer and the process is repeated until a desired height of a raw concrete block is reached.

In addition, also from the US 2007/0074484 A1 a method for the manufacture of components with light-conducting materials is known. In this process, light-conducting fibers are clamped in a frame of a molding box and then encapsulated with concrete. About it is from the US 2007/0074484 A1 It is known to peel light-conductive fabric layer by layer from a roll into a molding box and sequentially fill the molding box with concrete.

On this basis, it is an object of the present invention, at least partially solve the problems described with reference to the prior art. In particular, a method is to be specified in which a uniform wetting of the conductor arrangement with the base material is to be made possible, in particular suitable for flow or series production. In addition, the variety of variations should be increased in terms of the design of the devices achieved by the method, at the same time a cost-effective production is achieved.

These objects are achieved with the features of claim 1. Further advantageous embodiments will become apparent from the dependent formulated claims. It should be noted that the features listed individually in the claims in any technologically meaningful way, can be combined with each other and show other embodiments of the invention. The description, in particular in conjunction with the figures, explains further preferred embodiments of the invention.

• (a) Bereitstellen zumindest einer Leiteranordnung;
• (b) wenigstens teilweises Anordnen einer fließfähigen Masse, um die wenigstens eine Leiteranordnung in einem Reservoir;
• (c) Transportieren der zumindest einen Leiteranordnung mit der Masse von dem Reservoir zu einer von dem Reservoir beabstandeten Aufnahme;
• (d) Positionieren von Teilabschnitten der zumindest einen Leiteranordnung zueinander;
• (e) Verfestigen der Masse.

In the method according to the invention for producing a component having at least one conductor arrangement, at least the following steps are included:

• (a) providing at least one conductor arrangement;
• (b) at least partially disposing a flowable mass around the at least one conductor assembly in a reservoir;
• (c) transporting the at least one conductor assembly with the mass from the reservoir to a receptacle spaced apart from the reservoir;
• (D) positioning portions of the at least one conductor assembly to each other;
• (e) solidifying the mass.

With regard to step (a), it should be noted that the conductor arrangement is preferably provided in the manner of an endless material in a flat variant embodiment. For this purpose, the conductor arrangement preferably has flexible (wire and / or (textile) fiber-like structures), which are at least partially conductive for a medium, in particular light and / or electricity or the like. It is further preferred that the conductor arrangement is a self-supporting textile structure, the cohesion the conductor arrangement is thus maintained, in particular due to gravity and / or transport.

In step (b) flowable material, such as concrete and / or plastic, is now arranged around the at least one conductor arrangement. This means in particular that the flowable, possibly viscous, mass arranges itself on the conductor arrangement or wets and / or covers it. It is regularly desirable for the entire conductor arrangement to be uniformly surrounded by the flowable mass, at least in its direction of extent. Nevertheless, it is also possible to omit specific areas of, for example, several square centimeters or even larger areas in order, for example, to position other or further materials there.

The now pretreated, wetted with the flowable mass, conductor arrangement is then transported on. It should be expressed in particular with step (c) that here is not a simple pouring of the flowable mass takes place in a recording, but that the conductor assembly is transported into contact with the flowable mass and finally positioned variable for the final solidification process (step (d)). In step (d), in particular, folds, windings, stacks and similar constructions can be formed in order to bring different subsections of the conductor arrangement into desired positions relative to one another in which they are intended to solidify together with the flowable mass. If the conductor sections are in the desired position, the solidification of the mass can begin (step (e)), possibly even earlier.

It is clear that the above-described steps (a) to (e) may optionally take place at the same time and / or additional processes may additionally be carried out. This applies in particular to measures for checking the quality of the result of the individual steps, the application of further materials, the setting of desired environmental conditions and the like. It is particularly preferred that the method described here is carried out essentially continuously, so that therefore a kind of flow production is specified.

With regard to step (a), it is particularly preferable to produce a textile structure which is designed with at least one flexible optical waveguide. In such a textile structure, which is optionally formed in the manner of a so-called distance knitted fabric, (technical) textile fibers are combined to form a woven fabric, knitted fabric or a similar structure. In addition to these textile fibers or as a substitute for flexible translucent fibers can be incorporated into the structure. Preferably, these fibers extend transversely to the main extension plane of the structure. The fibers preferably have ends that are positioned on the one hand on the top and on the other hand on the underside of the concrete layer. These translucent fibers (which can be formed from PES (polyester), (un) coated PMMA (polymethyl methacrylate), PC (polycarbonate), glass or similar materials) conduct the light from the top to the bottom or vice versa. Such a construction of the concrete layer with a textile structure ensures that even very thin concrete layers can be used, especially during transport and / or assembly are not destroyed.

According to a further embodiment of the method, at least one reservoir with flowable mass is moved into the at least one conductor arrangement in step (b). This means, for example, that the conductor arrangement is immersed in the reservoir and / or a flow of the flowable mass is moved through. It is preferred that the flowable mass in the reservoir, possibly held by additional means is flowable, substantially constituting immobile material, and the conductor assembly is relatively moved therethrough. The speed and / or "depth" can be selected depending on the desired degree of wetting.

In this case, it is considered advantageous if the movement of the conductor arrangement takes place solely on the basis of gravity, in particular if it is impregnated with the flowable mass. This ensures an undisturbed distribution of the flowable mass on the conductor arrangement.

According to a further embodiment of the method, a plurality of layers of a conductor arrangement are formed in step (d). This can be done in such a way that, for example, a stack of several layers is formed continuously and in a meandering manner, wherein one layer is formed in each case by adjacent subsections of the conductor arrangement. Optionally, additional materials may be inserted between these layers. However, it is also possible that step (d) a separation process with respect to the conductor arrangement is made, so that the conductor arrangement is discontinuously positioned with the individual sections, in particular against each other twisted, offset and / or different conductor arrangements are positioned to each other. In this way, on the one hand, the mechanical property of the device can be influenced in the desired manner, but at the same time, the ultimately desired light effect effect of the component can be varied to a great extent.

For example, it is also proposed that the at least one conductor arrangement has a multiplicity of flexible light guides, in which step (d) layers with different orientation of the flexible light guides are formed. In other words, that means that, for example, a similar conductor arrangement can be manufactured or provided continuously, but this is then positioned in step (d) such that different light effects are achieved by the different arrangement of the subsections or layers. The advantages of a continuous production on the one hand and a flexible design of the components on the other hand are connected in a particularly cost-effective manner.

According to a development of the method, the conductor arrangement is wound onto a carrier during step (d). The wetted with the viscous, flowable mass conductor arrangement can be wound on carriers of different basic form. Due to the winding process, different orientations of the conductor arrangement can already be realized, so that likewise the variety of variations increases in view of the ultimately desired light effects. In addition, the winding on a support that this accommodates the components in a large volume, which is nevertheless space-saving, in particular for the possibly time-consuming solidification process, is arranged. The supports may have a surface which has a low wetting tendency with regard to the flowable mass and / or a removable intermediate layer (eg coating).

Furthermore, it is considered advantageous to separate the solidified mass after step (e) by separating at least one conductor arrangement. By this is meant in particular that the winding and / or laminations after removal of the carrier and / or while the carrier is still positioned in the winding is divided. In this way, in particular, facades and / or wall sections of the desired size can be produced.

In view of the above manufacturing method, a so produced device is proposed, which is formed with a mass comprising concrete and at least one conductor assembly comprising at least one flexible light guide comprising a transparent fiber material, wherein layers are provided different orientation of the flexible light guide. This means in other words that the layers, basically have the same structure of the conductor arrangement, but by their staggered, twisted and / or wetted with concrete position, however, may be different surfaces of the device connected to the flexible light guides, so here targeted Achieve light effects. In principle, such a component can also be produced in other ways, so that this embodiment of the component is also considered to be particularly advantageous over known components independently of the method described here according to the invention.

The present invention thus proposes, in particular, first to impregnate the textile conductor arrangement directly with the flowable mass (eg concrete suspension) and then to bring it "wet" into the desired position. The concrete suspension in this case has a viscosity which is adapted to the amount provided for adhesion to the conductor arrangement. This means in particular that the conductor arrangement can be assigned a capacity for concrete suspension, the z. B. on the type of fabric, the materials used, etc. is dependent. The viscosity is now preferably adjusted so that a well-defined, z. B. one of the maximum absorption capacity of the conductor assembly corresponding concrete amount per surface of the conductor arrangement is attached. The impregnated with concrete, textile, conductor arrangement can then be positioned with the desired distances from each other, for. B. by the thus generated cover layer of concrete made correspondingly thick and the conductor assembly is placed on each other. A meandering tray of impregnated, textile, conductor arrangement leads after a certain time to a structure with possibly a few 100 or even more than 1000 layers of photoconductive fibers in a high-viscosity concrete mass. This can then be solidified to the desired products and optionally further processed.

The invention and the technical environment will be explained in more detail with reference to FIGS. It should be noted that the figures show, but are not limited to, particularly preferred embodiments of the invention. They show schematically:

1 FIG. 1 shows a first embodiment of a method for producing a component, FIG.

2 FIG. 2 shows a second variant of a method for producing the component, FIG.

3 a possibility of separating an intermediate product to produce the components,

The 1 is intended to schematically illustrate a first embodiment of the method according to the invention. Here, first, a conductor arrangement 2 in the manner of a textile structure 5 provided, which is designed purely schematically as a role and thus to illustrate a continuous, possibly controlled or regulated, supply. The conductor arrangement 2 is then through a reservoir 7 with flowable mass 3 passed through, this mass 3 prefers concrete represents. On the ground 18 of the reservoir 3 is a corresponding opening 19 provided by which the conductor arrangement 2 , now with the crowd 3 wets that reservoir 7 leaves. The relative movement of the conductor arrangement 2 through the reservoir 7 or the mass 3 is by means of a transport device 8th realized, here a couple of rollers 9 includes, through which the conductor arrangement 2 goes down due to gravity. With the help of this transport device 8th becomes the concrete wetted ladder arrangement 2 now with the formation of several layers 10 in a recording 12 stored. This will be several subsections 2 arranged one above the other by changing the storage direction. Are in the recording 12 the desired number of layers 10 formed, then the conductor arrangement 2 separated and the subsequent conductor arrangement 2 will be in another (not shown here) recording 12 stored.

To generate these relative movements, it is proposed to have at least one device unit of the group reservoir 7 , Transport device 8th and recording 12 movable or to be made locally variable. For example, it is possible that the reservoir 7 in 1 can be moved horizontally and / or vertically, as well as possibly the recording 12 , It is preferred that the transport device 8th Here only serves for filing and therefore a (only) horizontal movement is sufficient. The individual possibilities of movement of the device units are indicated by white arrows in FIG 1 characterized.

With regard to an effective use of the flowable mass can also be a return 17 be provided with the no longer needed or excess mass 3 from the recording 12 (or the transport device 8th ) back to the reservoir 7 is promoted (in particular by using a pump 16 ). This aspect may also play an important role in the method proposed here.

A slightly different variant illustrates in 2 , Here is the transport device 8th Part of the reservoir 7 , is in particular at the outlet or the opening 19 in the ground 18 positioned. The transport device takes over 8th additionally the function of wetting the conductor arrangement 2 , In addition, the wetted conductor arrangement 2 then not stored in a recording, but here to a rotatable and variable movable support 11 wound (indicated by the direction of rotation 15 ).

3 illustrates now, like a wrap 13 , for example, in the preparation according to 2 arises, on to building elements 1 can be processed. The wrap 13 can be separated, for example, along the dotted line, so that a plurality of segments 14 is formed. These can also be separated or subdivided, so that ultimately the desired components 1 (here, for example, like bricks with optical fibers 6 , are formed). From this it is easy to see how simple and cost-effective a multitude of possibly differently designed components 1 can be reached with the method according to the invention.
