Description

Technical area

The invention relates to a method for producing concrete elements, in particular concrete blocks and / or concrete slabs with at least one predetermined surface structure. In the method, core concrete is poured into at least one mold for one or more stones and / or slabs and compacted, then a facing concrete layer is refilled and compacted and the concrete is then hardened. At least before the concrete hardens, the facing concrete layer is treated with at least one treatment device. The invention further relates to a device for producing concrete elements, in particular concrete blocks and / or concrete slabs, according to the preceding description.

Such concrete elements can for example in the form of concrete blocks according to DIN V 18500 , Garden design elements made of concrete according to the DIN EN 13198 , Pavement or concrete slabs according to the DIN EN 1338 or curbs made of concrete in accordance with DIN EN 1340.

State of the art

For example, the laid-open specification describes DE 10 2010 025 024 A1 a method for the production of a concrete block, in which first a core concrete is mixed and fed to a mold and a facing concrete is mixed and fed to the mold. The core concrete is poured into the form as the base layer of the concrete block and the facing concrete is poured into the form onto the core concrete as the top layer of the concrete block. The surface of the cover layer is provided with a multidimensional shape with at least one embossment and / or elevation. This is achieved by reshaping the surface of the cover layer with a corresponding form or pressure stamp or a bear plate.

The disadvantage of this method is that a separate molding or pressure stamp or a separate bearing plate has to be produced for each desired shape of the surface of the cover layer, which is very complex given a large number of different shapes.

Presentation of the invention

The object of the present invention is to provide a method for the production of concrete elements which enables a simpler, more flexible and faster production of different surface structures of the facing concrete layer. Another object of the present invention is to provide an apparatus for performing this method.

This object is achieved by the method for producing concrete elements according to claim 1 and the device for producing concrete elements according to claim 15.

A method is proposed for the production of concrete elements, in particular concrete blocks and / or concrete slabs with at least one predetermined surface structure. These can be concrete elements for use outdoors and / or indoors. The size of the concrete elements is not decisive for the present method. The thickness of the concrete elements is also immaterial as long as it is thick enough so that the surface structure can be formed on the concrete elements. Concrete elements within the meaning of the invention can, for example, be in the form of artificial stones according to DIN V 18500, garden design elements made of concrete according to DIN EN 13198, paving stones or slabs made of concrete according to DIN EN 1338 or curbs made of concrete according to DIN EN 1340.

The predetermined surface structure includes in particular depressions and / or elevations, the number, position, shape, length and / or depth or height of which can be selected individually over a wide range. There can be only one type of depressions or elevations or a combination of different depressions or elevations, for example long, thin depressions with a small depth combined with short, wide depressions with a greater depth. The surface structure can only have a decorative or possibly also informative character or, for example, also serve to provide slip resistance.

In the method, core concrete is poured into at least one mold for one or more stones and / or slabs, which is then at least partially compacted if necessary. This initially creates a core concrete layer in the mold. The core concrete is chosen so that it can withstand the stresses that act on the concrete element. Since the core concrete is usually not visible when the concrete element is used, a coarser and cheaper concrete can be used for the core concrete. The concrete can be compacted, for example, using stamping tools that are pressed onto the concrete with high pressure.

A facing concrete is topped up on top of the core concrete and thus a facing concrete layer is created which, for example, is already at least partially compacted afterwards can. Then the concrete, namely both the core concrete and the facing concrete or the layers produced therefrom, is preferably cured together. At least before the concrete hardens, the facing concrete layer is treated with at least one treatment device. The treatment device is designed so that it can produce the specified surface structure on the concrete elements.

According to the invention, the treatment device is moved in a program-controlled manner by means of a displacement and / or adjustment device to one and / or more surface positions of the facing concrete layer and / or along at least one surface section and / or a surface area of the facing concrete layer, so that at least one predetermined surface structure of the facing concrete layer is generated at least in sections .

Since the process of the treatment device is program-controlled, different surface structures can be achieved very easily by changing the program. Different surface structures can therefore be produced flexibly and quickly.

The displacing and / or adjusting device can preferably move the treatment device to any position on the surface of the facing concrete layer, so that every area of the surface of the facing concrete layer can also be treated.

The surface of the facing concrete layer is treated with one or more treatment elements of the treatment device. One such treatment element is a brush which, when moved over the facing concrete layer, creates a large number of thin, closely spaced depressions in the facing concrete layer. Another treatment element is a spatula, which can be designed in various shapes and sizes. A spatula can be used to create punctiform impressions as well as short or long linear depressions.

Particularly preferably, the treatment element of the treatment device is also selected under program control and the depth of the depression to be produced in the facing concrete layer is determined under program control.

The at least one treatment device is advantageously moved in a program-controlled manner by means of at least one robot arm of a robot unit. The robot unit can be integrated into systems for the production of concrete elements in a space-saving manner and the treatment device can reach all surface positions of the facing concrete layer by means of a correspondingly designed robot arm.

It is advantageous if at least the treatment device is moved in a program-controlled manner by means of at least one control routine executed in a control device. The control device can also control further process steps in the production of concrete elements, for example providing the at least one mold, filling and / or compacting the core concrete and / or facing concrete layer and / or transporting the finished concrete elements. The control routine can preferably be easily switched over to different surface structures and / or reprogrammed to generate new surface structures.

It is also advantageous if the treatment device is controlled in such a way that concrete elements are produced with at least one identical or highly similar surface structure or a different, preferably individual, surface structure. Concrete elements with an identical or highly similar surface structure have a particularly uniform appearance, while concrete elements with a different surface structure are reminiscent of natural stones. An individual surface structure also increases the exclusivity of the concrete elements.

The compaction is advantageously carried out by means of a press and the treatment device is moved between the facing concrete layer and the press. For the steps of filling and compacting core concrete and facing concrete and treating the facing concrete layer, the concrete elements do not have to be moved, so the concrete elements can be produced in a small space.

It is also advantageous if at least one application device applies additional material to the facing concrete layer before compacting the facing concrete layer. With the additional material, the structure and / or the appearance of the surface of the facing concrete layer can be changed even further.

It is advantageous if the application device is moved to one and / or more surface positions of the facing concrete layer and / or along at least one surface section and / or a surface area of the facing concrete layer for at least some sections of the additional material to be applied to the facing concrete layer. The application device can then preferably reach the entire surface of the facing concrete layer and thus target it Apply additional material in any position on the surface of the facing concrete layer. The application device can be moved by means of the displacement or adjustment device, which also moves the treatment device. The application device and the treatment device can be moved together and each can be used as required. Alternatively, the displacement or adjustment device can pick up the application device, move it and set it down again and then pick up, move and set down the treatment device again. Another variant is that the application device is moved by means of a further displacement and / or adjustment device.

The application device is advantageously moved in a program-controlled manner by means of the robot arm or by means of at least one further robot arm of the robot unit. If the application device is moved by means of the robot arm, which also moves the treatment device, only one robot arm is required for moving the application device and treatment device, which is both cost-effective and space-saving.

It is advantageous if the application device is moved in a program-controlled manner by means of the control routine executed in the control device or by means of a further control routine executed in the control device. The control routine can preferably be quickly switched to different surface configurations and / or easily programmed.

It is advantageous if the application device is controlled in such a way that concrete elements are produced with identical or highly similar additional material or with different, preferably individually applied, additional material. Analogous to the surface structure treated by the treatment device, concrete elements with identical or highly similar applied additional material have a particularly uniform appearance, while concrete elements with different, preferably individually applied additional material are reminiscent of natural stones and also have increased exclusivity.

The additional material is advantageously conveyed to the application device and / or the additional material is carried along in a container with the application device and the container is filled as required. The conveying can take place, for example, via a feeder line such as a conveyor belt or a pipeline, wherein conveying means such as a worm drive or a slide can be provided. The feeder line can run along the robot arm, for example. When the additional material is conveyed to the application device, the application device can be made relatively small. If, on the other hand, the additional material is carried along in a container with the application device, the feeder line can be dispensed with, but the container must be moved together with the application device.

It is advantageous if the type and / or quantity of the additional material applied is varied along the surface section, since this creates particularly attractive concrete elements.

It is advantageous if the additional material is finishing material and / or color material. Refining material can be, for example, aggregate, grains of precious or semi-precious stones, mica and / or metal shavings. In addition to the optical effect, the finishing material can also have other positive effects on the surface properties of the facing concrete layer, for example improved adhesion or increased durability due to less abrasion. The color material can also fulfill aesthetic purposes or also serve to convey information, for example as delimitation strips or information boards integrated into the concrete element.

Furthermore, a device for producing concrete elements, in particular concrete blocks and / or concrete slabs, is proposed. According to the invention, the production of the concrete elements takes place according to the method according to the preceding description. In particular, concrete elements with different surface structures can be produced flexibly and quickly by means of the device.

The device comprises at least one treatment device and a displacement and / or adjustment device, wherein the displacement and / or adjustment device is designed to move the treatment device to one and / or more surface positions of a facing concrete layer of the concrete element and / or along at least one surface section and / or to move a surface area of the facing concrete layer.

Ways of Carrying Out the Invention

Identical reference symbols are used in the figures for elements of the invention that are the same or have the same effect. Furthermore, for the sake of clarity, only reference symbols are shown in the individual figures that are necessary for the description of the respective figure.

1a shows a schematic longitudinal section through a device 1 for the production of concrete elements 2 and 1b shows a schematic plan view of this device 1 . With the concrete elements 2 it can in particular be concrete blocks or concrete slabs. Concrete elements 2 Within the meaning of the invention, for example in the form of concrete blocks according to DIN V 18500, garden design elements made of concrete according to DIN EN 13198, paving stones or slabs made of concrete according to DIN EN 1338 or curbs made of concrete according to DIN EN 1340.

The concrete elements 2 are thereby in a corresponding form 3 manufactured. The number of in the form 3 provided recesses for concrete elements 2 can of course be used by the in 1b shown differ; Usually a larger number of concrete elements 2 produced simultaneously. It is also conceivable that two or more shapes 3 side by side for the production of concrete elements 2 be used.

In the in the 1a and 1b illustrated first step of the process for the production of concrete elements 2 becomes core concrete 4th in the form 3 filled. Filling in the core concrete 4th takes place by means of a filling device 5 , shown here as a funnel-shaped boiler 6th with an outlet 7th is shown. The filling device 5 is in the present embodiment along two rails 8th in a transverse direction Q the device 1 movable. Furthermore are the rails 8th including the filling device 5 preferably also along a longitudinal direction L. the device 1 provided movably (for the sake of clarity not shown). Because it can be moved in the transverse direction Q and / or longitudinal direction L. can the filling device 5 all recesses of the form 3 reach and with core concrete 4th fill. Filling the form 3 with core concrete 4th takes place in such a controlled manner via a control and / or regulating unit (not shown in the figures) that a predetermined amount and thus a predetermined fill level of core concrete 4th into the recesses of the mold 3 is filled. This forms after the core concrete has hardened 4th a core concrete layer of the concrete element 2 out.

The exact design of the filling device 5 and the devices for moving the filling device 5 is not essential for the process according to the invention. For example, there is a filling device 5 conceivable in which only a long hose, which is connected to a concrete reservoir, to the recesses of the mold 3 is moved. It is also possible, for example, that the method of the filling device 5 takes place by means of a robot kinematics comprising at least rotatably or pivotably interconnected robot arms.

In the in the 2a and 2 B The next step shown is, for example, the core concrete 4th at least partially compressed. For this purpose, press bars 9 fortified stamp 10 a press 11 with high pressure on the core concrete 4th pressed. The pressure and the duration of compaction depend, among other things, on the composition of the core concrete 4th as well as the thickness of the core concrete layer 4th from.

On the compacted core concrete 4th then, as in 3a and 3b shown, Facing concrete 12 filled. This is done in the same way as pouring the core concrete 4th , this in 1a and 1b is shown. For filling in the facing concrete 12 can either use the filling device 5 be used with the core concrete 4th has been filled or a further filling device can be provided. The advantage of the last-mentioned solution is that cleaning of the filling device 5 when changing core concrete 4th on facing concrete 12 (and vice versa) is not applicable. Filling the form 3 with facing concrete 12 takes place in turn controlled via the control and / or regulating unit, in such a way that a predetermined amount and thus a predetermined fill level of facing concrete 12 into the recesses of the mold 3 on the existing core concrete 4th is filled.

In a variant of the invention not shown in the figures, before filling with facing concrete 12 on the filled core concrete or the core concrete layer created thereby 4th reinforcement can be provided. Steel mats, steel fibers or similar materials, for example, can be used as the means for producing the reinforcement, which is preferably of flat design. After the reinforcement has been introduced, the facing concrete is placed on top 12 filled. The reinforcement is particularly advantageous for stiffening the concrete element 2 . This enables in particular the production of large-format concrete elements 2 or special special formats. The reinforcement is preferably put into the mold by machine during the manufacturing process 3 brought in.

In the 4a and 4b The application of additional material is now an optional intermediate step 13 onto the facing concrete layer produced by introducing the facing concrete 12 shown. This step is preferably carried out after filling. Is a compaction of the facing concrete or the facing concrete layer 12 provided, depending on the additional material used 13 or its physical properties, the introduction of the additional material 13 before or after compacting the facing concrete 12 be performed.

With additional material 13 it can be, for example, finishing material, such as stone grains, grains of precious or semi-precious stones, mica and / or metal chips and / or color material. The additional material fulfills optical or aesthetic purposes, but can also ensure improved adhesion or increased durability in the case of finishing material due to less abrasion. Furthermore, the facing concrete layer 12 Applied color material serve to convey information, for example as in the concrete element 2 integrated delimitation strips or information boards. Finally, the additional material 13 also have a functional significance, for example by creating a rough surface to increase slip resistance.

The additional material 13 is by an application device 14th on the facing concrete layer 12 upset. The application device 14th is by means of a displacement and / or adjustment device 15th movable, preferably such that all surface positions of the facing concrete layer 12 from the application device 14th can be achieved. The method of the applicator 14th takes place under program control, preferably by means of a control routine executed in the control and / or regulating unit (not shown).

The application device 14th can be program-controlled at almost any surface position of the facing concrete layer 12 are moved and the additional material at these surface positions 13 on the facing concrete layer 12 be applied. The application device 14th but can also be along a surface section and / or a surface area of the facing concrete layer 12 and continuously additional material 13 on the facing concrete layer 12 raise. The type and / or the amount of additional material applied can be used for special effects along the surface section 13 can be varied.

The moving and / or adjusting device 15th is present as a robot unit or robot kinematics with at least one robot arm 16 formed, wherein the application device 14th preferably at the free end of the at least one robot arm 16 is arranged. The working range of the robot unit or the robot kinematics is designed such that the application device 14th all surface positions of the facing concrete layer 12 can reach. When the applicator 14th is not used, the robot arm will 16 in the in the 1b , 2 B and 3b Move the rest position shown. The robot arm is in the rest position 16 from the shape 3 removed and therefore not disruptive to other facilities, such as the filling device 5 or the devices for compacting the concrete layers 4th , 12 .

For the present invention, the specific technical design of the displacement or adjustment device is 15th not decisive. So can the application device 14th be moved, for example, with the aid of a rail system not shown here, the rails preferably being moved by the application device 14th at all surface positions of the facing concrete layer 12 enable.

In the 5a and 5b is the compaction of the facing concrete layer 12 shown. Compaction of the facing concrete layer 12 takes place in the same way as in the 2a and 2 B compaction of the core concrete shown 4th by means of the on the press bars 9 attached stamps 10 the press 11 .

On the compaction of the facing concrete layer 12 that follows in the 6a and 6b treatment of the facing concrete layer shown 12 with a treatment facility 17th . In the present embodiment, the treatment device 17th together with the application device 14th at the end of the robot arm 16 arranged. However, other variants are conceivable: the treatment facility can 17th at the end of the robot arm 16 be arranged and the application device 14th at the end of another robot arm. Alternatively, the application device 14th and the treatment facility 17th be designed in such a way that it is connected to a coupling at the end of the robot arm 16 can be connected. The application device 14th and the treatment facility 17th are then each, when they are not needed, placed in a parking position and coupled to the end of the robot arm for applying additional material or treating the facing concrete layer. There is also the possibility that no application device 14th is provided; then just the treatment facility 17th at the end of the robot arm 16 arranged.

The treatment device can preferably 17th by means of the moving and / or adjusting device 15th at every surface position of the facing concrete layer 12 are proceeded. The method is program-controlled, preferably by means of a control routine executed in the control device.

Treating the surface of the facing concrete layer 12 takes place with one or more treatment elements 22nd the treatment facility 17th that with the facing concrete layer 12 be brought into contact. The height of the treatment elements can preferably be 22nd , and thus the immersion depth in the facing concrete layer 12 can be changed under program control. The greater the immersion depth, the greater the recess in the facing concrete layer 12 is produced. As treatment elements 22nd For example, brushes or spatulas come into consideration.

The treatment elements 22nd can at a certain surface position of the facing concrete layer 12 create a punctual recess or in contact with the facing concrete layer 12 of the moving or adjusting device 15th are moved so that linear depressions are generated.

The use of the treatment elements 22nd takes place in a program-controlled manner, preferably also by means of the control routine executed in the control device. A wide variety of surface structures can be created in the facing concrete layer 12 be generated. The surface structures can be created in such a way that they are suitable for each concrete element 2 are identical or at least highly similar. The surface structures can also be created in such a way that they are for each concrete element 2 are different, preferably individual. Furthermore, it is also possible to generate surface structures in such a way that, for example, a linear depression on the edge of one concrete element 2 ends and then on the corresponding edge of the next concrete element 2 continues, so that a coherent surface structure is created.

On treating the surface of the facing concrete layer 12 Then follows the hardening of the concrete, not shown here, with which the concrete elements 2 are finished.

7th shows a schematic longitudinal section through an application device 14th . The application device 14th has two containers 18th on where additional material 13 is held. It is preferably a matter of different additional material 13 so that different designs of the concrete elements 2 possible are. Depending on the desired concrete element 2 are also application devices 14th with just one container 18th or more than two containers 18th conceivable.

The containers 18th have a top opening 19th and a lower opening 20th on. Via the top opening 19th can be additional material 13 be refilled if necessary. In the area of the lower opening 20th is a movable cover element 21st arranged. The cover element 21st can the lower opening 20th close completely, partially open or completely open. Will be the lower opening 20th partially or fully released, the additional material 13 from the container 18th on the facing concrete layer 12 fall. Depending on the degree of release of the lower opening 20th there are no, little or a lot of additional material per unit of time 13 on the facing concrete layer 12 . The cover element 21st is preferably moved in a program-controlled manner, particularly preferably by means of the control routine executed in the control device.

Finally shows 8th a schematic longitudinal section through a treatment device 17th who have favourited two treatment elements 22nd having, of course, a different number of treatment elements 22nd is conceivable. The one treatment element 22nd is included as a spatula 22.1 formed while the other treatment element 22nd as a brush 22.2 is trained.

Every treatment element 22nd is an adjustment unit 23 associated with the vertical position of the treatment element 22nd and thus the immersion depth of the treatment element 22nd in the facing concrete layer 12 specifies. Depending on the immersion depth, there are different depressions in the facing concrete layer 12 . The adjustment unit 23 is preferably operated under program control, particularly preferably by means of the control routine executed in the control device.

In an advantageous development of the invention, the treatment elements are 22nd in addition, rotatably mounted about a vertical axis. The rotation about the vertical axis can, for example, also be program-controlled by the adjustment unit 23 respectively. By rotating the treatment elements 22nd one can achieve for example that the orientation of the treatment element 22nd relative to that of the treatment facility 17th covered surface distance always remains the same. Alternatively, one can use the treatment elements 22nd during the treatment of the surface of the facing concrete layer 12 rotate so that the rotation results in visually interesting effects.
