Bei der Herstellung einer Betondecke, insbesondere beim Bau von Betonfahrbahndecken, wird der Beton in der Regel von einem Gleitschaltungsfertiger form- und lagegerecht eingebaut und dazu mit einer Glätteinrichtung, z. B. einem Querglätter, geglättet. In einigen Fällen wird zusätzlich ein Längsglätter eingesetzt.In the production of a concrete pavement, especially in the construction of concrete pavements, the concrete is usually installed by a Gleitschaltungs paver form and correct position and this with a smoothing device, eg. As a cross straightener, smoothed. In some cases, a longitudinal smoother is additionally used.
Vor dem Aufbringen des Nachbehandlungsmittels durch die Nachbehandlungsmaschine muss die Decke noch eine abschließende Oberflächenbearbeitung mit einer dem Verwendungszweck entsprechenden Oberflächentextur erhalten. Dadurch soll die Griffigkeit und der Fahrkomfort erhöht, sowie das Reifen-Fahrbahn-Geräusch vermindert werden.Before applying the aftertreatment agent through the aftertreatment machine, the blanket must still be given a final surface finish having a surface texture corresponding to the intended use. This is to increase the grip and ride comfort, and reduce the tire-road noise.
Hinsichtlich der Texturierung der Betonoberflächen bestehen bei den Auftraggebern unterschiedliche Anforderungen hinsichtlich der Art der aufzubringenden Textur.With regard to the texturing of the concrete surfaces, the clients have different requirements with regard to the type of texture to be applied.
Dadurch kann es erforderlich sein, dass die Nachbehandlungsmaschinen zeitaufwändig umgerüstet werden müssen, um je nach Wunsch des Auftraggebers eine gewünschte Texturierung zu erzielen. Ein weiterer Nachteil besteht darin, dass die Umbausätze separat bereitgehalten werden müssen.As a result, it may be necessary for the aftertreatment machines to be converted in a time-consuming manner in order to achieve a desired texturing as desired by the client. Another disadvantage is that the conversion kits must be kept separately.
Die
Durch Drehung der Arbeitsrichtung der Schneidwalze und Zurückfahren der Nachbehandlungsmaschine kann eine zweite Rillenstruktur erzeugt werden, deren Rillen die erste Rillenstruktur schneiden.By rotating the working direction of the cutting roller and retracting the aftertreatment machine, a second groove structure can be produced, the grooves of which intersect the first groove structure.
Wird die Maschine zurückgefahren oder soll ein anderer Winkel der Schneidwalze zur Arbeitsrichtung eingestellt werden, muss die Schneidwalze angehoben werden.If the machine is moved back, or if another angle of the cutting roller is to be adjusted to the working direction, the cutting roller must be raised.
Eine Koordination von Geschwindigkeiten ist nicht erforderlich.Coordination of speeds is not required.
Aus der
Der Erfindung liegt daher die Aufgabe zugrunde, eine Nachbehandlungsmaschine sowie ein Verfahren zum nachträglichen Bearbeiten von frisch gefertigten Betonschichten zu schaffen, die in einfacher Weise unterschiedliche Texturieraufgaben ohne zeitaufwändige Umrüstzeiten und ohne großen apparativen Aufwand ausführen können.The invention is therefore an object of the invention to provide an aftertreatment machine and a method for retrofitting of freshly made concrete layers that can perform different texturing tasks without time-consuming changeover times and without great expenditure on equipment in a simple manner.

Die Steuerung kann demzufolge die Fahrgeschwindigkeit messen und in Abhängigkeit eines gewünschten Texturierwinkels die Verfahrgeschwindigkeit der Texturiereinrichtung während der Vorwärts- oder Rückwärtsfahrt in Querrichtung steuern oder die Verfahrgeschwindigkeit der Texturiereinrichtung erfassen und die Fahrgeschwindigkeit steuern. Außerdem besteht die Möglichkeit, beide Geschwindigkeiten in Abhängigkeit des gewünschten Texturierwinkels zu steuern.The invention advantageously provides that a control unit detects the driving speed and / or the travel speed of the texturing device during forward or reverse travel and controls the travel speed and / or the travel speed as a function of a desired texturing angle, wherein the texturing angle is determined by the ratio of the Speeds results. The controller can therefore measure the vehicle speed and, depending on a desired texturing angle, control the speed of movement of the texturing device during the forward or reverse travel in the transverse direction or detect the speed of movement of the texturing device and control the driving speed. It is also possible to control both speeds depending on the desired texturing angle.
Die Steuerungseinheit kann bei vorgegebener Verfahrgeschwindigkeit der Texturierungswerkzeuge die Fahrgeschwindigkeit steuern oder bei vorgegebener Fahrgeschwindigkeit die Verfahrgeschwindigkeit der Texturierungswerkzeuge steuern.The control unit can control the driving speed for a given travel speed of the texturing tools or control the travel speed of the texturing tools for a given travel speed.

Detektoren können die Fahrgeschwindigkeit des Maschinenrahmens in Längsrichtung und die Verfahrgeschwindigkeit der Texturiereinrichtung in Querrichtung messen und die Messignale an die Steuerung übertragen.Detectors can measure the travel speed of the machine frame in the longitudinal direction and the traversing speed of the texturing device in the transverse direction and transmit the measurement signals to the controller.
Die Texturiereinrichtung kann eine Quertexturiereinrichtung sein und weist vorzugsweise eine feste, sich in Fahrtrichtung erstreckende Länge auf.The texturing device may be a cross texturing device and preferably has a fixed, extending in the direction of travel length.
Die Texturiereinrichtung kann auch eine sich in Fahrtrichtung erstreckende veränderliche Länge aufweisen, indem z.B. Verlängerungselemente anbringbar sind.The texturizer may also have a variable length extending in the direction of travel, e.g. Extension elements are attachable.
Die Texturiereinrichtung kann auch eine Längstexturiereinrichtung sein, bei der die Texturierwerkzeuge in Querrichtung mit einer vorgebbaren Geschwindigkeit verfahrbar sind.The texturing device can also be a longitudinal texturing device, in which the texturing tools can be moved in the transverse direction at a predeterminable speed.

Werden die Texturierwerkzeuge in einer horizontalen Ebene endlos geführt, in der sie ständig mit der Betonschicht im Eingriff sind, erzeugen die in Fahrtrichtung vorderen Texturierwerkzeuge eine Texturierung unter einem vorgegebenen, relativ zu der Fahrtrichtung positiven Winkel und die in Fahrtrichtung hinteren Texturierwerkzeuge eine Texturierung unter dem gleichen, relativ zu der Fahrtrichtung negativen Winkel.If the texturing tools are continuously guided in a horizontal plane in which they are constantly engaged with the concrete layer, the front in the direction of travel texturing produce a texturing under a predetermined, relative to the direction of positive angle and the rear in the direction of texturing a texturing under the same , negative angle relative to the direction of travel.
Werden die rücklaufenden Texturierwerkzeuge angehoben zurückgeführt oder in einer vertikalen oder in einer zur Oberfläche der Betonschicht schrägen Ebene endlos geführt, in der sie während des Rücklaufs nicht die Betonschicht berühren, kann eine reine Schrägtexturierung ausgeführt werden.If the returning texturing tools are returned in a raised position or are endlessly guided in a vertical or inclined plane to the surface of the concrete layer in which they do not touch the concrete layer during the return, a pure oblique texturing can be carried out.
Je nach Dienstleistungsauftrag kann demzufolge die Nachbehandlungsmaschine allein aufgrund der Steuerung ohne Umrüstung so gesteuert werden, dass flexibel beliebige Texturierungsmuster aufgebracht werden können.Accordingly, depending on the service order, the aftertreatment machine can be controlled solely by virtue of the control without retrofitting in such a way that any desired texturing pattern can be flexibly applied.
Eine zur Aufbringung einer Texturierung quer verfahrbare Arbeitseinrichtung kann vorzugsweise eine Quertexturiereinrichtung sein, die in eine Ruheposition verfahrbar ist, in der die Quertexturiereinrichtung außer Eingriff mit der Betonschicht ist.A working device which is transversely movable for application of a texturing may preferably be a cross texturing device which can be moved to a rest position in which the cross texturing device is disengaged from the concrete layer.

In the raised position, it is ensured that the cross texturing device does not come into contact either with the concrete layer or with other aggregates.
Bei einem bevorzugten Ausführungsbeispiel ist vorgesehen, dass der Maschinenrahmen parallel zur Arbeitsrichtung verlaufende Längsträger und quer zur Arbeitsrichtung verlaufende Querträger aufweist, wobei die quer zur Arbeitsrichtung verlaufenden Querträger zur variablen Einstellung der Spurweite der Laufwerke und zur Anpassung an die Breite der Betonschicht teleskopierbar sind.In a preferred embodiment, it is provided that the machine frame has parallel to the working direction extending longitudinal beams and transverse to the direction of the cross member, wherein the transversely extending to the direction of the cross member for variable adjustment of the track width of the drives and to adapt to the width of the concrete layer are telescopic.

Es kann vorgesehen sein, dass die Quersprüheinrichtung in der Betriebsposition in Verlängerung der Quertexturiereinrichtung vorzugsweise in Arbeitsrichtung nacheilend oder einseitig oder beidseitig neben der Quertexturiereinrichtung angeordnet und mit der Quertexturiereinrichtung gemeinsam bewegbar ist.It can be provided that the cross-spray device in the operating position in extension of the cross-texturing preferably in the working direction lagging or unilaterally or both sides next to the Quertexturiereinrichtung and is movable together with the Quertexturiereinrichtung.
Der Maschinenrahmen kann von zwei einzelnen jeweils seitlich angeordneten längeren Laufwerken getragen werden, oder von insgesamt vier Laufwerken, wobei auf jeder Seite des Maschinenrahmens zwei hintereinander fahrende Laufwerke angeordnet sein können. Die Laufwerke sind über Hubsäulen mit dem Maschinenrahmen verbunden über die eine Höhenverstellung des Maschinenrahmens relativ zum Boden erfolgen kann.The machine frame can be carried by two individual laterally arranged longer drives, or by a total of four drives, wherein two consecutive drives can be arranged on each side of the machine frame. The drives are connected via lifting columns with the machine frame over which a height adjustment of the machine frame can be made relative to the ground.
Vorzugsweise ist vorgesehen, dass die Quer- oder Längstexturiereinrichtungen Werkzeuge aufweisen, die mit einem Schnellwechselsystem befestigt sind. Auf diese Weise ist es möglich, die Werkzeuge ohne lange Rüstzeiten auszuwechseln, oder defekte Werkzeuge ohne nennenswerten Zeitverlust auszuwechseln.It is preferably provided that the transverse or longitudinal texturizing devices have tools which are fastened with a quick-change system.

Die Erfindung sieht gemäß einem Verfahren zum nachträglichen Bearbeiten von frisch gefertigten Betonschichten in vorteilhafter Weise vor, dass in Abhängigkeit eines gewünschten Texturierwinkels die Fahrgeschwindigkeit und/oder die Verfahrgeschwindigkeit der Texturiereinrichtung erfasst und während einer Vorwärts- oder Rückwärtsfahrt die Fahrgeschwindigkeit und/oder die Verfahrgeschwindigkeit der Texturiereinrichtung in Querrichtung gesteuert wird, wobei sich der Texturierwinkel aus dem Verhältnis der Geschwindigkeiten ergibt.According to a method for the subsequent processing of freshly produced concrete layers, the invention advantageously provides that the driving speed and / or the travel speed of the texturing device is detected as a function of a desired texturing angle, and the driving speed and / or the travel speed of the texturing device during a forward or reverse travel is controlled in the transverse direction, wherein the texturing angle results from the ratio of the speeds.
Vorzugsweise wird bei vorgegebener Verfahrgeschwindigkeit der Texturierungswerkzeuge die Fahrgeschwindigkeit gesteuert oder bei vorgegebener Fahrgeschwindigkeit die Verfahrgeschwindigkeit der Texturierungswerkzeuge in einem von dem eingestellten Texturierwinkel vorgegebenen Verhältnis gesteuert.Preferably, at a given travel speed of the texturing tools, the travel speed is controlled or, for a given travel speed, the travel speed of the texturing tools is controlled at a ratio predetermined by the set texturing angle.
Durch das Einbringen einer Quertexturierung über eine Strecke vorgegebener Länge in einer Fahrtrichtung und anschließend über eine sich anschließende weitere Strecke gleicher Länge in einer entgegengesetzten Fahrtrichtung können aufeinanderfolgende Texturierungen unter einem Texturierwinkel in gleicher Richtung in die Betonschicht eingebracht werden.By introducing a transverse texturing over a distance of predetermined length in one direction of travel and then over a subsequent further distance of the same length in an opposite direction of travel successive texturing can be introduced under a texturing in the same direction in the concrete layer.

Der Maschinenrahmen 2 weist eine für einen Transport auf einem Transportfahrzeug geeignete Tiefe auf, so dass die Maschine auf dem Transportfahrzeug auf einer Straße zum Einsatzort transportiert werden kann. Der Maschinenrahmen mit Quer- und Längsträgern 18,28 weist im Vergleich zur Tiefe ein Vielfaches der Breite auf, wobei zur Anpassung an eine bestimmte Fahrbahnbreite beispielsweise Verbreiterungselemente einsetzbar sind oder der Maschinenrahmen 2 teleskopierbar ist. Dabei kann in der in
Die Nachbehandlungsmaschine 1 weist ein Fahrwerk mit mehreren Rädern und/oder Kettenlaufwerken 4 auf, die den Maschinenrahmen 2 über Hubsäulen 8 höhenverstellbar tragen.The
Die Verwendung von insgesamt vier Laufwerken 4 an den seitlichen Enden der Nachbehandlungsmaschine 1 hat den Vorteil einer höheren Stabilität, wobei die Anordnung der Arbeitseinrichtungen, insbesondere der Texturiereinrichtungen 3 in Fahrtrichtung 50 mittig zwischen den Laufwerken 4 den Vorteil hat, dass der Einfluss von Massenträgheitskräften auf den Maschinenrahmen 2 beim Anfahren oder Abbremsen der Nachbehandlungsmaschine 1 minimiert werden. Darüber hinaus wirken sich dennoch stattfindende leichte Nickbewegungen weniger stark auf die Position der Texturierungseinrichtung relativ zur Betonfläche aus.The use of a total of four
Die Räder oder Kettenlaufwerke 4 können insbesondere im Falle von vier Kettenlaufwerken 4 von einer in
Die Kettenlaufwerke 4 sind hydraulisch angetrieben, lenkbar und höhenverstellbar.The crawler tracks 4 are hydraulically driven, steerable and height adjustable.
Die Quersprüheinrichtung 6 ist wie beim Stand der Technik an einem quer über die Betonschicht 10 bzw. die Fahrbahnbreite verfahrbaren Querantrieb befestigt. Desweiteren ist an dem Querantrieb die Quertexturiereinrichtung 3, z. B. aus einem Bürstenaggregat, befestigt. Die Quertexturiereinrichtung 3 ist dabei, wie am besten aus
Die Schienenführung des Schlittens ist zu diesem Zweck in einem Bereich seitlich neben der Betonschicht 10 um einen vorgegebenen Betrag angehoben, so dass die Quertexturiereinrichtung 3 neben der Betonschicht 10 bzw. Fahrbahn in einen angehobenen Zustand in eine Ruheposition überführt werden kann.The rail guide of the carriage is raised for this purpose in an area laterally adjacent to the
Die Quersprüheinrichtung 6, wie sie in der
Ist ein gleichbleibender Texturierwinkel für die gesamte Breite der Betonschicht 10 erwünscht, wird ein bestimmtes Verhältnis zwischen Fahrgeschwindigkeit der Nachbehandlungsmaschine 1 und die Querbewegungsgeschwindigkeit der Quertexturiereinrichtung in der Steuereinheit 24 eingestellt. Es versteht sich, dass die Querbewegungsgeschwindigkeit der Quertexturiereinrichtung 3 in Abhängigkeit von der Fahrgeschwindigkeit der Nachbehandlungsmaschine 1 eingestellt werden kann, oder auch umgekehrt.If a constant texturing angle for the entire width of the
Beispielsweise kann die Fahrgeschwindigkeit des Querantriebs für die Quertexturiereinrichtung 3 in einfacher Weise durch Anschläge für die Quertexturiereinrichtung 3 auf der linken und rechten Seite der Nachbehandlungsmaschine 1 erfasst werden, indem die Zeitdauer für die Querbewegung über die Breite der Betonschicht 10 gemessen wird.For example, the travel speed of the transverse drive for the
Selbstverständlich können auch Daten aus dem Querantrieb zur Bestimmung der Geschwindigkeit in Querbewegungsrichtung 40 verwendet werden.Of course, data from the transverse drive can also be used to determine the speed in the
Schließlich ist es auch möglich, sowohl die Fahrgeschwindigkeit als auch die Quergeschwindigkeit der Quertexturiereinrichtung gemeinsam in Abhängigkeit vom eingestellten Texturierwinkel zu steuern.Finally, it is also possible to control both the driving speed and the transverse speed of the transverse texturing device jointly as a function of the set texturing angle.
Dadurch, dass das Geschwindigkeitsverhältnis während der Quertexturierung auch verändert werden kann, ist es schließlich auch möglich, ein Texturiermuster mit unterschiedlichen Texturierwinkeln in die Betonschicht 10 einzubringen.Due to the fact that the speed ratio can also be changed during the transverse texturing, finally it is also possible to introduce a texturing pattern with different texturing angles into the
Dann besteht die Möglichkeit, dass die Nachbehandlungsmaschine um die Länge der Quertexturiereinrichtung 3 vorfährt (
Die Steuereinheit kann hierbei so konfiguriert sein, dass die Maschine nach Abschluss eines Texturierabschnitts automatisch um einen Fahrweg, der der Länge der Texturierungseinrichtung entspricht nach vorne gefahren wird.The control unit can in this case be configured so that the machine is automatically moved to the end of a Texturierabschnitts to a distance equal to the length of the texturing device to the front.
Im Falle der Bewegung der Texturierwerkzeuge 30 in einer horizontalen Ebene durchlaufen die rücklaufenden Texturierwerkzeuge 30 erneut die Betonschicht 10 in entgegengesetzter Richtung, so dass bei kontinuierlicher Vorwärtsfahrt der Nachbehandlungsmaschine 1 mit der Längstexturiereinrichtung ein Rautenmuster erzeugt werden kann.In the case of the movement of the
Laufen die Texturierwerkzeuge 30 in einer zur Oberfläche der Betonschicht 10 schrägverlaufenden Ebene, besteht die Möglichkeit, nur die in eine Querrichtung bewegten Texturierwerkzeuge 30 in Eingriff mit der Betonschicht 10 zu bringen, während die in Gegenrichtung rücklaufenden Texturierwerkzeuge 30 außer Eingriff mit der Betonschicht 10 sein können.If the
Die Texturiereinrichtungen können eine Schnellwechseleinrichtung für Werkzeuge aufweisen, so dass in kurzer Zeit unterschiedliche Bürsten oder Werkzeuge, z. B. Stahlzinken oder Kunststoffbürsten zum Einsatz kommen können.The Texturiereinrichtungen can have a quick change device for tools, so that in a short time different brushes or tools, eg. As steel tines or plastic brushes can be used.
