Description

Die Erfindung betrifft eine System zur Bildung einer Rüttelbohle nach dem Oberbegriff des Patentanspruchs 1 sowie eine entsprechende Rüttelbohle.The invention relates to a system for forming a vibrating screed according to the preamble of claim 1 and a corresponding vibrating screed.

Bekannt sind Rüttelbohlen, die an zwei seitlichen Schienen, die entlang einer zu glättenden Betonoberfläche angeordnet sind, als einteilige oder aus zwei parallelen Flächen bestehende Glättfläche geführt wird. Dabei ist die Glättfläche mit einem Vibrator verbunden und wird über eine zu erstellende Betonoberfläche gezogen. Um eine flexible Anpassung an die Breite der zu fertigenden Betonoberfläche zu ermöglichen, ist es dabei bekannt, die Rüttelbohlen aus einzelnen Segmenten zusammenzusetzen, die an Verbindungsstellen miteinander verbunden werden und in der Wirkung als eine Rüttelbohlen quer zu der sich ergebenden Längserstreckung mit ihrer sich ergebenden Arbeitsbreite über die Betonoberfläche gezogen werden.Vibrating screeds are known which are guided on two lateral rails, which are arranged along a concrete surface to be smoothed, as a one-piece smoothing surface or consisting of two parallel surfaces. The smoothing surface is connected to a vibrator and is pulled over a concrete surface to be created. In order to allow flexible adaptation to the width of the concrete surface to be produced, it is known to assemble the vibrating screeds from individual segments that are connected to one another at connection points and act as vibrating screeds across the resulting longitudinal extension with their resulting working width be pulled over the concrete surface.

Nachteilig an diesem Stand der Technik ist jedoch, dass eine relativ große Anzahl von unterschiedlichen Segmenten vorgehalten werden muss und insgesamt nur eine geringe Flexibilität gegeben ist. Insbesondere erfordert die genaue Abstimmung auf eine erforderliche Länge der Rüttelbohle, beispielsweise die Breite einer Betonfahrbahnfläche, so viele Segmente mit unterschiedlichen Längen zur Verfügung zu haben, dass die gewünschte Länge für jeden Anwendungsfall und jede Baustelle individuell und exakt gebildet werden kann.The disadvantage of this prior art, however, is that a relatively large number of different segments must be kept and that there is only little flexibility overall. In particular, the exact adjustment to a required length of the vibrating screed, for example the width of a concrete road surface, requires so many segments with different lengths to have available that the desired length can be formed individually and precisely for each application and each construction site.

Zusätzlich entstehen auch Probleme, wenn durch räumliche Einschränkungen die Bauhöhe der Rüttelbohlen nicht zu hoch sein darf. Schließlich kann es auch zu Problemen kommen, eine ausreichende Steifigkeit der Rüttelbohlen insgesamt zu gewährleisten, durch die allein eine gute Oberflächenqualität der zu bearbeitenden Betonoberfläche erreicht werden kann.In addition, problems arise if the construction height of the vibrating screed must not be too high due to spatial restrictions. Finally, problems can also arise in ensuring sufficient rigidity of the vibrating screeds as a whole, by which alone a good surface quality of the concrete surface to be processed can be achieved.

Bei den bekannten Ausführungsformen ist ein Segment der Rüttelbohlen dabei im Querschnitt aus einer in der Zugrichtung vorderen und hinteren Glättfläche aufgebaut, die auf der zu bearbeitenden Betonoberfläche aufliegen und durch eine im Querschnitt dreieckige, offene Rahmenstruktur verbunden sind. Oftmals weisen die zu erstellenden Betonoberflächen im Querschnitt ein Profil auf und sind nicht eben. Um solche Flächen erstellen zu können, ist es möglich, die einzelnen Segmente zueinander um jeweils einen Winkel relativ zueinander abzuknicken. Dies kann beispielsweise dadurch erfolgen, indem die Rahmenstrukturen der Segmente im oberen Bereich mit derjenigen Rahmenstruktur des jeweiligen benachbarten Segments über Gewindestangen und eine Spannmutter verbunden ist. Dadurch kann der Abstand eingestellt und somit ein Knickwinkel der im unteren Bereich der Glättflächen gelenkig verbundenen Segmente relativ zueinander festgelegt werden.In the known embodiments, a segment of the vibrating screed is constructed in cross section from a front and rear smoothing surface in the pulling direction, which rest on the concrete surface to be processed and are connected by an open frame structure with a triangular cross section. Often times the ones to be created Concrete surfaces have a profile in cross section and are not even. In order to be able to create such surfaces, it is possible to bend the individual segments to each other by an angle relative to each other. This can be done, for example, by connecting the frame structures of the segments in the upper area to that frame structure of the respective adjacent segment via threaded rods and a clamping nut. As a result, the distance can be set and thus a kink angle of the segments connected in an articulated manner in the lower region of the smooth surfaces can be set relative to one another.

Nachteilig an diesem Stand der Technik ist, dass bei sehr kurzen benötigten Arbeitsbreiten, beispielsweise wenn nur ein Segment eingesetzt wird oder eine Verbindung aus zwei Segmenten, sich ein relativ unhandlich zu handhabender Aufbau ergibt, der auch im Verhältnis relativ schwer ist. Umgekehrt kann bei einer sehr langen Rüttelbohle, die aus vielen Segmenten aufgebaut ist, die Steifigkeit nicht mehr ausreichend sein, wenn die Rahmenstruktur nicht ausreichend hoch und kräftig ausgelegt ist.The disadvantage of this prior art is that with very short working widths required, for example when only one segment is used or a connection of two segments, the result is a structure that is relatively unwieldy and difficult to handle. Conversely, in the case of a very long vibrating beam made up of many segments, the rigidity can no longer be sufficient if the frame structure is not designed to be sufficiently high and strong.

Insgesamt ergibt sich das Problem, dass eine Vielzahl möglicher und denkbarer Längen und Festigkeiten einer Rüttelbohlen benötigt werden, für die sehr viele unterschiedliche Segmente eingesetzt und somit kostenintensiv viele Segmente vorgehalten bzw. gekauft werden müssen.Overall, the problem arises that a large number of possible and conceivable lengths and strengths of vibrating screeds are required, for which a large number of different segments are used and therefore many segments have to be kept or purchased at high cost.

Zur Erzeugung der Vibrationen, mit denen die Rüttelbohlen die Betonoberfläche bearbeitet, ist es bekannt, einen Verbrennungs- oder Elektromotor vorzusehen, der über eine durch alle Segmente durchlaufende Welle auf der Welle angeordnete Unwuchtgewichte als Vibratoren antreibt.To generate the vibrations with which the vibrating screeds work on the concrete surface, it is known to provide an internal combustion or electric motor which drives unbalanced weights as vibrators via a shaft that runs through all segments.

Nachteilig an diesem Stand der Technik ist, dass hier kaum eine Anpassungsmöglichkeit an spezielle Gegebenheiten und einen punktuell höheren Bedarf an Vibrationsleistung besteht.The disadvantage of this state of the art is that there is hardly any possibility of adaptation to special conditions and that there is a higher need for vibration power at certain points.

Ebenso ist in dem Stand der Technik bekannt, jeweils durch einen Elektromotor angetriebene Vibratoren einzusetzen, die auf den Segmenten montiert sind und insbesondere auch vollständig gekapselt ausgeführt werden können, ohne äußere drehbare Wellen.It is also known in the prior art to use vibrators driven by an electric motor, which are mounted on the segments and, in particular, can also be designed completely encapsulated without external rotating shafts.

Hier ist jedoch eine möglichst große Flexibilität wünschenswert.However, the greatest possible flexibility is desirable here.

Segmente zum Aufbau einer Rüttelbohle sowie eine entsprechende Rüttelbohle sind aus der EP 2 531 654 B1 der Anmelderin bekannt.Segments for building a vibrating screed and a corresponding vibrating screed are from the EP 2 531 654 B1 known to the applicant.

Aus der US4261694A und DE102012100902A1 ist auch eine Rüttelbohle bekannt.From the US4261694A and DE102012100902A1 a vibrating beam is also known.

Es ist daher Aufgabe der vorliegenden Erfindung, ein System mit mindestens einem Segment sowie weiteren Elementen, mit denen eine Rüttelbohle gebildet werden kann, sowie eine entsprechende Rüttelbohle vorzusehen, das die zuvor genannten Nachteile vermeidet und mit dem flexibel unter geringen Kosten und mithilfe weniger Bauelemente eine Vielzahl von individuell angepassten Rüttelbohlen erstellt werden kann.It is therefore the object of the present invention to provide a system with at least one segment and further elements with which a vibrating screed can be formed, as well as a corresponding vibrating screed that avoids the disadvantages mentioned above and with the flexible at low cost and with the help of few components a Variety of individually adapted vibrating screeds can be created.

Die Aufgabe wird durch ein System bestehend aus mindestens einem Segment mit den Merkmalen des Patentanspruchs 1 sowie einer Mithilfe eines solchen Systems erstellten Rüttelbohlen nach Patentanspruch 18 gelöst. Vorteilhafte Weiterbildungen werden durch die Unteransprüche angegeben.The object is achieved by a system consisting of at least one segment with the features of claim 1 as well as vibrating screeds according to claim 18 created with the aid of such a system. Advantageous further developments are given by the subclaims.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass bei einem System zur Bildung einer Rüttelbohle, wobei das System mindestens eine Glättfläche und mindestens eine Rahmenstruktur umfasst, die mindestens eine Glättfläche und die mindestens eine Rahmenstruktur über lösbare Verbindungen zu einer Einheit verbunden werden können, sodass die Glättfläche allein als Segment einer Rüttelbohle oder die Einheit aus Rahmenstruktur und Glättfläche als Segment einer Rüttelbohle einsetzbar sind.The object is achieved according to the invention in that in a system for forming a vibrating screed, the system comprising at least one smoothing surface and at least one frame structure, the at least one smoothing surface and the at least one frame structure can be connected to a unit via detachable connections, so that the smoothing surface can be used alone as a segment of a vibrating screed or the unit of frame structure and smoothing surface as a segment of a vibrating screed.

Vorteilhaft bildet das System einen Baukasten, durch den Segmente in der erforderlichen Steifigkeit und umgekehrt, wenn eine entsprechend aufwändige Rahmenstruktur hoher Steifigkeit nicht erforderlich ist, leichte Segmente gebildet werden können. Die lösbaren Verbindungen können dabei insbesondere Schraubenverbindungen sein. Denkbar ist jedoch auch jede Kombination mit anderen lösbaren Verbindungen oder eine grundsätzliche Verwendung einer anderen lösbaren Verbindung, insbesondere auf Klemmwirkung beruhender Verbindungen. Eine aus dem System gebildete Rüttelbohle bzw. aus dem gebildeten Segment und eventuell weiteren Segmenten gebildete Rüttelbohle wird insbesondere zur Bearbeitung einer frischen Betonoberfläche eingesetzt, kann jedoch grundsätzlich auch für die Oberflächenbearbeitung anderer Baustoffe eingesetzt werden. Die hier und nachfolgend beschriebenen Elemente des Systems können grundsätzlich aus Stahl, aber vor allem auch aus Aluminium gebildet werden. Es sind Ausführungen des Systems rein aus Aluminiumbauteilen, oder auch Bauteile kombiniert aus Aluminium mit Stahlelementen sowie aus reinen Stahlelementen denkbar. Die Bauteile aus unterschiedlichen Materialien können dabei innerhalb eines Systems kombiniert werden. Durch das beschriebene System kann mit wenigen vorgehaltenen Bauteilen eine große Anzahl von unterschiedlichen Rüttelbohlen gebildet werden, die individuell angepasst sind an die jeweiligen Einsatzzwecke. Es ergeben sich dadurch erhebliche Kostenersparnisse, da beispielsweise für einen neuen Einsatzzweck nur wenige Elemente des Systems nachgekauft werden müssen, bis die erforderliche Rüttelbohle gebildet werden kann und nicht eine Vielzahl von verschiedenen Segmenten gekauft werden muss. Durch die lösbaren Verbindungen und die sich ergebende Möglichkeit des Zerlegens ergeben sich auch Vorteile bei der Lagerhaltung und Aufbewahrung. Die Elemente des Systems können auch zum Teil sehr kostengünstig gefertigt werden, wenn weitest möglich handelsübliche Standardprofile und -elemente genutzt werden können.The system advantageously forms a modular system by means of which segments with the required rigidity and vice versa, if a correspondingly complex frame structure of high rigidity is not required, light segments can be formed. The releasable connections can in particular be screw connections. However, any combination with other releasable connections or a basic use of another releasable connection, in particular connections based on a clamping effect, is also conceivable. A vibrating screed formed from the system or from the segment formed and possibly Vibratory screed formed in further segments is used in particular for processing a fresh concrete surface, but can in principle also be used for surface processing of other building materials. The elements of the system described here and below can in principle be made of steel, but above all also of aluminum. Versions of the system made purely from aluminum components, or also components made from aluminum with steel elements and from purely steel elements are conceivable. The components made of different materials can be combined within one system. With the system described, a large number of different vibrating screeds can be formed with just a few components, which are individually adapted to the respective application. This results in considerable cost savings, since, for example, only a few elements of the system have to be purchased for a new application before the required vibrating beam can be formed and a large number of different segments do not have to be purchased. The releasable connections and the resulting possibility of dismantling also result in advantages in terms of warehousing and storage. Some of the elements of the system can also be manufactured very inexpensively if commercial standard profiles and elements can be used as far as possible.

Vorteilhaft ist die Glättfläche aus zwei Profilen gebildet, wobei Querträger mit den Profilen verschraubt sind und diese verbinden.The smoothing surface is advantageously formed from two profiles, with cross members being screwed to the profiles and connecting them.

Es wird insgesamt als Glättfläche ein Rechteckelement gebildet, dessen schmale Seiten durch zwei Querträger gebildet werden, wobei im Bedarfsfall weitere Querträger an beliebigen Stellen eingefügt werden, um eine höhere Steifigkeit zu erreichen. Die Längsseiten können dabei durch übliche Standardnormprofile, beispielsweise Winkelprofile, oder auch spezielle Profile gebildet werden, wobei an der Unterseite jeweils eine die Oberfläche, insbesondere eine Betonoberfläche, bearbeitende Fläche besteht.Overall, a rectangular element is formed as a smooth surface, the narrow sides of which are formed by two cross members, with additional cross members being inserted at any point if necessary in order to achieve greater rigidity. The long sides can be formed by customary standard profiles, for example angle profiles, or also special profiles, with an area on the underside that processes the surface, in particular a concrete surface.

Es können mindestens zwei Rahmenstrukturen mit verschiedenen Höhen vorgesehen sein.At least two frame structures with different heights can be provided.

Durch unterschiedlich hohe Rahmenstrukturen, insbesondere in zwei Höhen, aber auch mehr Höhenstufen, die mithilfe des Systems gebildet werden können, kann eine Steifigkeit des jeweiligen Segments an die gewünschte Gesamtsteifigkeit der aus diesen gebildeten Rüttelbohlen angepasst werden. So ist es bei entsprechender Auslegung der Rahmenstruktur, bei zwei Höhenstufen mit der höheren, möglich, große Gesamtarbeitsbreiten der gebildeten Rüttelbohle zu erreichen. In einem Beispiel, bei dem ein Segment ohne zusätzliche Rahmenstruktur als "Small", ein Segment mit einer Rahmenstruktur der niedrigeren Höhe als "Medium" und mit der großen Höhe als "Large" bezeichnet wird, kann mit der "Large"-Ausführung eine Arbeitsbreite von 25 m in ausreichender Steifigkeit erreicht werden. Insbesondere bei einer Ausführung ohne Rahmenstruktur ergibt sich eine sehr niedrige Bauhöhe die zusammen mit einem niedrigen Gewicht den Einsatz an schwer zugänglichen Orten wie zum Beispiel Tunneln, Tunnelquerschlagsohlen, Tunnelzwischendecken oder Tunnelbanquette erleichtert.Due to frame structures of different heights, in particular at two heights, but also more height levels that can be formed with the aid of the system, the rigidity of the respective segment can be adapted to the desired overall rigidity of the vibrating screeds formed from them. With an appropriate design of the frame structure, with two height levels with the higher one, it is possible to achieve large overall working widths of the vibrating screed formed. In an example in which a segment without an additional frame structure is referred to as "Small", a segment with a frame structure of the lower height as "Medium" and with the high height as "Large", the "Large" version allows a working width of 25 m can be achieved with sufficient rigidity. A design without a frame structure in particular results in a very low overall height which, together with its low weight, makes it easier to use in hard-to-reach places such as tunnels, tunnel cross-passages, intermediate tunnel ceilings or tunnel banquettes.

In einer vorteilhaften Ausgestaltung des Systems ist die Rahmenstruktur aus lösbaren, dreiecksförmigen Trägerelementen gebildet, die insbesondere in einem Winkel gegenüber der Senkrechten zur Glättfläche angeordnet sind und die durch einen lösbaren Obergurt, insbesondere in Form eines Hohlprofils, verbunden sind.In an advantageous embodiment of the system, the frame structure is formed from detachable, triangular support elements, which are arranged in particular at an angle to the perpendicular to the smoothing surface and which are connected by a detachable upper flange, in particular in the form of a hollow profile.

Dies ergibt insgesamt, im Querschnitt des Segments betrachtet, eine Dreiecksform mit einer auf der zu bearbeitenden Betonoberfläche aufliegenden Seite des Dreiecks, die eine steife und zugleich leichte Struktur ergibt. Dabei können für die verschiedenen Höhen der Rahmenstruktur, die identischen Obergurte bzw. evtl. sonstige Elemente der Rahmenstruktur eingesetzt werden und lediglich abweichende dreiecksförmige Trägerelemente mit unterschiedlichen Höhen. Eine besonders gut handhabbare und günstige Form ergibt sich, wenn die Trägerelemente in einem Winkel gegenüber der Senkrechten zur Glättfläche angeordnet werden und bei der Bildung des Segments beispielsweise so befestigt werden, dass sie sich von den Kopfseiten der Glättfläche zum inneren des Segments zu neigen.Overall, viewed in the cross section of the segment, this results in a triangular shape with one side of the triangle resting on the concrete surface to be processed, which results in a stiff and at the same time light structure. For the different heights of the frame structure, the identical upper chords or possibly other elements of the frame structure can be used and only different triangular support elements with different heights. A particularly easy-to-use and favorable shape is obtained when the carrier elements are arranged at an angle to the perpendicular to the smooth surface and when the segment is formed, for example, are attached in such a way that they incline from the head sides of the smooth surface towards the inside of the segment.

Vorteilhaft sind die die dreiecksförmigen Trägerelemente auf den Querträgern aufgesetzt, insbesondere mit diesen verschraubt.The triangular support elements are advantageously placed on the cross members, in particular screwed to them.

Das dreiecksförmige Trägerelement der Rahmenstruktur bildet somit zugleich einen zuvor beschriebenen Querträger, der zusammen mit den Profilen die Glättfläche ausbildet.The triangular support element of the frame structure thus at the same time forms a previously described cross member which, together with the profiles, forms the smooth surface.

Vorteilhaft können zur Bildung einer Rüttelbohle aus mehreren Segmenten Verbindungsmittel zur Verbindung eine Segments mit weiteren Segmenten vorgesehen sind, die lösbar an den Glättflächen montierbar sind, insbesondere Verbindungsmittel, die eine Rohrhülse aufweisen, durch die ein Verbindungsbolzen geführt werden kann.Advantageously, to form a vibrating screed from several segments, connecting means for connecting a segment with further segments can be provided which can be detachably mounted on the smooth surfaces, in particular connecting means which have a tubular sleeve through which a connecting bolt can be guided.

Dadurch können mehrere Segmente zu einer Rüttelbohle zusammengesetzt werden, wobei insbesondere auf Höhe der Glättfläche eine abwinkelbare Verbindung vorliegt, indem eine Drehbewegung in einem bestimmten Winkelbereich um den Verbindungsbolzen möglich ist.As a result, several segments can be put together to form a vibrating screed, with a connection that can be angled, in particular at the level of the smoothing surface, in that a rotary movement around the connecting bolt is possible in a specific angular range.

Die Verbindungsmittel können mit einem Querträger verbunden sein.The connecting means can be connected to a cross member.

Dies ermöglicht eine leichte Montage an den Kopfenden der Glättfläche.This enables easy assembly at the head ends of the smoothing surface.

In einer vorteilhaften Ausgestaltung des Systems sind Glättflächen und Rahmenstrukturen in unterschiedlichen Längen vorgesehen, sodass eine Rüttelbohlen aus Segmenten unterschiedlicher Längen zusammengesetzt werden kann, um eine gewünschte Arbeitsbreite zu erreichen.In an advantageous embodiment of the system, smooth surfaces and frame structures are provided in different lengths so that a vibrating screed can be composed of segments of different lengths in order to achieve a desired working width.

Vorteilhaft ist es dadurch für die Ausbildung von Segmenten in unterschiedlichen Längen nur erforderlich eine geringe Anzahl von Bauteilen in unterschiedlichen Ausführungen einzusetzen, um mithilfe zusammengesetzter Segmente eine bestimmte Arbeitsbreite der gebildeten Rüttelbohle erreichen zu können. Beispielsweise müssen bei den zuvor beschriebenen Ausführungen der Rahmenstruktur mit einem Obergurt sowie der Glättfläche mit seitlichen Profilen zur Bildung eines Segments mit einer abweichenden Länge zunächst nur die zwei seitlichen Profile in einer abweichenden Länge zur Verfügung stehen sowie ein entsprechender Obergurt in einer angepassten Länge. Bei einer stark vergrößerten Länge des Segments müssen nur eventuell zusätzliche Rahmenelemente, etwa dreiecksförmige Trägerelemente und Querträger, vorgesehen werden, falls dies die Steifigkeit erfordert.It is therefore advantageous to use only a small number of components in different designs for the formation of segments in different lengths in order to be able to achieve a certain working width of the vibrating screed formed with the aid of assembled segments. For example, in the above-described designs of the frame structure with an upper chord and the smoothing surface with lateral profiles to form a segment with a different length, only the two lateral profiles in a different length and a corresponding upper chord in an adapted length must initially be available. In the case of a greatly increased length of the segment, additional frame elements, for example triangular support elements and cross members, may only have to be provided if the rigidity requires this.

Es können Kurzsegmente mit beidseitigen Verbindungsmitteln zur Verbindung mit weiteren Segmenten vorgesehen sein.Short segments with connecting means on both sides can be provided for connecting to further segments.

In der erforderlichen Gesamtlänge bzw. Arbeitsbreite einer Rüttelbohlen können dadurch sehr kleine Anpassungen vorgenommen werden. Auch ist es möglich, dadurch eine Oberfläche mit einer Krümmung durch eine Polygonlinie mit vielen kleinen Knickwinkeln zu bilden. Es ist beispielsweise möglich, als solches Kurzsegment einen Querträger einzusetzen.This means that very small adjustments can be made to the required total length or working width of a vibrating screed. It is also possible to form a surface with a curvature through a polygon line with many small kink angles. For example, it is possible to use a cross member as such a short segment.

Es können durch Längsverbinder in der Rahmenstruktur zwei Glättflächen über eine Lücke verbunden werden.Straight connectors in the frame structure can be used to connect two smooth surfaces via a gap.

Durch die Möglichkeit einer solchen Lücke in der Arbeitsbreite der Rüttelbohlen kann diese über Hindernisse hinweg gezogen werden, etwa eine Reihe aus der Betonfläche hervorstehender Elemente, ohne dass die Bearbeitung unterbrochen werden muss.The possibility of such a gap in the working width of the vibrating screed allows it to be pulled over obstacles, such as a row of elements protruding from the concrete surface, without having to interrupt the processing.

Die Längsverbinder können dreiecksförmige Trägerelemente verbinden.The straight connectors can connect triangular support elements.

In vorteilhafter Ausgestaltung des Systems sind Zugsegmente vorhanden, die zur ein- oder beidseitigen Verbindung mit den Segmenten vorgesehen sind und die über eine Elektro- und/oder Handwinde sowie ein Zugseil die Rüttelbohle über eine zu fertigende Oberfläche ziehen können.In an advantageous embodiment of the system, pull segments are provided which are provided for one or both sides to be connected to the segments and which can pull the vibrating screed over a surface to be manufactured via an electric and / or hand winch and a pull rope.

Insbesondere kann dadurch vorteilhaft auch durch ein Zugsegment zur beidseitigen Verbindung mit einem Segment eine Rüttelbohlen in der Mitte gezogen werden. Vor allem aber ist es dadurch möglich, eine Fläche zu bearbeiten, die kein paralleles Rechteck darstellt, sondern sich insbesondere verbreitert. In einem solchen Fall wird eine Rüttelbohle mit einem zentral angeordneten Zugsegment vorgesehen, und je nach Bedarf werden mit fortschreitender Arbeitsrichtung zusätzlich Segmente seitlich angefügt oder eventuell auch abgenommen, um die gesamte Fläche abzudecken bzw. die Arbeitsbreite mit der Vorwärtsbewegung der Rüttelbohle an die jeweiligen Erfordernisse anzupassen.In particular, a vibrating screed can advantageously be pulled in the middle by a pulling segment for connection to a segment on both sides. Above all, however, it is thereby possible to process an area that is not a parallel rectangle, but rather broadens in particular. In such a case, a vibrating screed with a centrally arranged traction segment is provided and, as required, additional segments are added laterally or possibly also removed in order to cover the entire area or to adapt the working width to the respective requirements with the forward movement of the vibrating screed .

An der Glättfläche können lösbar montiert Vibratoren, insbesondere Elektromotorvibratoren vorgesehen sein.Detachably mounted vibrators, in particular electric motor vibrators, can be provided on the smoothing surface.

Dadurch kann durch die Anzahl von Vibratoren und deren Positionierung die gewünschte Vibrationsleistung individuell angepasst werden. Insbesondere Elektromotorvibratoren können dabei vorteilhaft in komplett gekapselter Ausführung zum Einsatz kommen, bei der äußerlich keine sich drehenden Teile vorhanden sind und die daher gegenüber Feuchtigkeit und Verschmutzung unempfindlich sind. Ein Obergurt der Rahmenstruktur kann dabei vorteilhaft als Versorgungskanal für Elektroleitungen dienen.As a result, the desired vibration output can be individually adapted through the number of vibrators and their positioning. In particular, electric motor vibrators can advantageously be used in a completely encapsulated design, in which there are no rotating parts on the outside and which are therefore insensitive to moisture and contamination. An upper belt of the frame structure can advantageously serve as a supply channel for electrical lines.

Die Vibratoren können auf einem der Querträger montiert sein.The vibrators can be mounted on one of the cross members.

Vorteilhaft ergibt sich dadurch eine direkte und gute Einleitung der Vibrationen des Vibrators auf die seitlichen Profile der Glättfläche und somit die wirksamen Flächen. Gleichzeitig erfolgt eine weitere Aussteifung der Glättfläche bzw. des gebildeten Segments.This advantageously results in a direct and effective introduction of the vibrations of the vibrator onto the lateral profiles of the smoothing surface and thus the effective surfaces. At the same time, the smoothing surface or the segment formed is further reinforced.

Es können längsverstellbare Oberverbinder zur Verbindung zweier Segmente vorgesehen sein.Longitudinally adjustable top connectors can be provided to connect two segments.

In einer günstigen Ausgestaltung des Systems sind die Oberverbinder über Gewinde längsverstellbar und können mit der Rahmenstruktur verbunden werden und/oder einem auf der Glättfläche montierbaren Halter.In a favorable embodiment of the system, the upper connectors are longitudinally adjustable by means of threads and can be connected to the frame structure and / or a holder that can be mounted on the smooth surface.

Zusammen mit den auf die Glättfläche direkt wirkenden und um einen Winkel abknickbaren Verbindungselementen kann über die Verbinder eine steife und feste Verbindung zum Nachbarsegment erreicht werden, wobei zugleich der Winkel zwischen den Segmenten eingestellt werden kann. Dies ist sowohl möglich, wenn der Oberverbinder auf die Rahmenstruktur wirkt und somit deutlich oberhalb der Verbindungselemente angeordnet ist, als auch, wenn ein spezieller Halter für die Oberverbinder auf der Glättfläche bei einer Ausführung des Segments ohne Rahmenstruktur vorgesehen wird. Dadurch können Radien in der zu bearbeitenden Oberfläche polygonal angenähert werden, indem eine Mehrzahl von Knickwinkel zwischen benachbarten Segmenten bzw. Kurzsegmenten eingestellt wird. Es ist auch denkbar, gebogene Glättflächen einzusetzen. Durch letzteres kann jede beliebige Biegung auf die Betonoberfläche übertragen werden als gebogene Oberfläche.Together with the connecting elements that act directly on the smoothing surface and can be bent at an angle, the connector can be used to achieve a rigid and firm connection to the neighboring segment, with the angle between the segments being able to be adjusted at the same time. This is possible both when the top connector acts on the frame structure and is thus arranged well above the connecting elements, and when a special holder for the top connector is provided on the smooth surface when the segment is designed without a frame structure. As a result, radii in the surface to be machined can be approximated polygonally by setting a plurality of kink angles between adjacent segments or short segments. It is also conceivable to use curved smooth surfaces. Through the latter, any Bend transferred to the concrete surface is called a curved surface.

Der Oberverbinder kann Gewinde und Gewindehülsen aufweisen und doppelt oder mehrfach angeordnet werden.The top connector can have threads and threaded sleeves and can be arranged twice or more than once.

Es kann ein Haltegriff zur Befestigung an einer Glättfläche vorgesehen sein, um ein Segment per Hand zu bewegen.A handle can be provided for attachment to a smoothing surface in order to move a segment by hand.

Der Haltegriff kann an einem der Profile der Glättfläche befestigt werden.The handle can be attached to one of the profiles of the smoothing surface.

Dies ermöglicht den Einsatz einer Glättfläche allein, aber auch eines Segments mit Rahmenstruktur, als handgeführtes Betonoberflächenbearbeitungswerkzeug bzw. "Handpatsche".This enables the use of a smoothing surface alone, but also a segment with a frame structure, as a hand-held concrete surface processing tool or "hand slap".

Die Aufgabe wird auch gelöst durch eine Rüttelbohle, die aus einem zuvor beschriebenen System gebildet wird.The object is also achieved by a vibrating screed which is formed from a system described above.

Es ergeben sich die bereits zuvor beschriebenen Vorteile.The advantages already described above result.

Die Fig. 1 zeigt Beispiele von mithilfe des erfindungsgemäßen Systems gebildeter Segmente 1 mit verschiedener Höhe in perspektivischer Seitenansicht. Dargestellt sind die Segmente jeweils links in der Zeichnung von der Rückseite und rechts in der Zeichnung von der Vorderseite, wobei eine Ausführung eines Segments 1 ohne Rahmenstruktur, auch bezeichnet als "Small"-Segment 2, eine Ausführung eines Segments 1 mit einer Rahmenstruktur 4 mittlerer Höhe, auch bezeichnet als "Medium"-Segment 3, und ein Segment 1 mit einer Rahmenstruktur 4 großer Höhe, auch bezeichnet als "Large"-Segment 5, dargestellt sind. Eine Glättfläche 6 ist dabei aus zwei Profilen 7 sowie diese verbindenden Querträgern 8 gebildet.The Fig. 1 shows examples of segments 1 formed using the system according to the invention with different heights in a perspective side view. The segments are shown in each case on the left in the drawing from the rear and on the right in the drawing from the front, an embodiment of a segment 1 without a frame structure, also referred to as a "small" segment 2, an embodiment of a Segments 1 with a frame structure 4 of medium height, also referred to as “medium” segment 3, and a segment 1 with a frame structure 4 of great height, also referred to as “large” segment 5, are shown. A smoothing surface 6 is formed from two profiles 7 and cross members 8 connecting them.

Bei den Ausführungsformen mittlerer und großer Höhe, bzw. dem "Medium"-Segment 3 sowie dem "Large"-Segment 5, besteht die Rahmenstruktur 4 aus dreiecksförmigen Trägerelementen 9, die in dem vorliegenden Beispiel mit den Querträgern 8 verschraubt sind, sowie einem Obergurt 10. In dem vorliegenden Beispiel sind in dem Obergurt 10 Versorgungsleitungen angeordnet, die beispielsweise für den Anschluss hier nicht dargestellter Elektromotorvibratoren dienen, und daher Stecker- bzw. Steckdosenelemente 11 vorgesehen. Die Darstellung der Fig. 1 zeigt noch die Anordnung von Verbindungsmitteln 12 in Form einer Rohrhülse 13 auf den Querträgern 8 des "Medium"-Segments 3 und des "Large"-Segments 5. Dieses kann verschraubt sein. Es ist aber auch möglich, dass kombinierte Elemente aus einem Querträger 8 und einer Rohrhülse 13 gebildet werden, bei denen die Rohrhülse 13 mit dem Querträger 8 verschweißt ist.In the medium and high-height embodiments, or the "medium" segment 3 and the "large" segment 5, the frame structure 4 consists of triangular support elements 9, which in the present example are screwed to the cross members 8, as well as an upper flange 10. In the present example, supply lines are arranged in the upper belt 10, which are used, for example, to connect electric motor vibrators (not shown here), and therefore plug or socket elements 11 are provided. The representation of the Fig. 1 also shows the arrangement of connecting means 12 in the form of a tubular sleeve 13 on the cross members 8 of the "medium" segment 3 and the "large" segment 5. This can be screwed. But it is also possible that combined elements are formed from a cross member 8 and a tubular sleeve 13, in which the tubular sleeve 13 is welded to the cross member 8.

Alle drei dargestellten Segmente 1 haben dieselbe Länge bzw. Arbeitsbreite und können modular aus den Elementen des Systems als Bausatz zusammengestellt werden. Beispielsweise müssen nur die dreiecksförmigen Trägerelemente 9 ausgetauscht werden, um ein "Medium"-Segment 3 in ein "Large"-Segment 5 umzuwandeln. Es müssen insbesondere nicht alle drei Segmente 1 als vollständige Bauteile vorgehalten werden, um flexibel diese zur Verfügung zu haben, sondern es können innerhalb des Systems als Bausatz mit Austausch weniger Elemente oder dem Hinzufügen einer Rahmenstruktur 3 Segmente 1 als "Small"-Segment 2, "Medium"-Segment 3, oder "Large"-Segment 5 je nach Bedarf gebildet werden.All three segments 1 shown have the same length or working width and can be put together as a modular kit from the elements of the system. For example, only the triangular carrier elements 9 have to be exchanged in order to convert a “medium” segment 3 into a “large” segment 5. In particular, all three segments 1 do not have to be kept as complete components in order to have these flexibly available, but rather within the system as a kit with replacement of a few elements or the addition of a frame structure 3 segments 1 as "small" segment 2, "Medium" segment 3 or "Large" segment 5 can be formed as required.

Die Fig. 2a zeigt eine Detailseitenansicht eines Verbindungsmittels 12 mit dreiecksförmigem Trägerelement 9. Den Elementen der Fig. 1 entsprechende Elemente sind hier und in den folgenden Figuren mit denselben Bezugszeichen versehen. Das Verbindungsmittel 12 besteht aus der Rohrhülse 13, die auf dem Querträger 8 angeordnet ist, der mit dem dreiecksförmigen Trägerelement 9 verschraubt ist. In dem dargestellten Ausführungsbeispiel handelt es sich um das dreiecksförmige Trägerelement 9 eines "Large"-Segments 5 der Fig. 1, das in einem steilen Winkel gegenüber der Horizontalen angeordnet ist. Dadurch ergibt sich eine große Aufbauhöhe der Rahmenstruktur 4 in der Fig. 1.The Fig. 2a shows a detailed side view of a connecting means 12 with a triangular support element 9. The elements of FIG Fig. 1 Corresponding elements are given the same reference symbols here and in the following figures. The connecting means 12 consists of the tubular sleeve 13, which is arranged on the cross member 8 which is screwed to the triangular carrier element 9. In the illustrated embodiment, it is the triangular support element 9 of a "large" segment 5 of the Fig. 1 that in one is arranged at a steep angle to the horizontal. This results in a large structural height of the frame structure 4 in the Fig. 1 .

Die Fig. 2b zeigt eine weitere Detailseitenansicht eines Verbindungsmittels 12 mit dreiecksförmigem Trägerelement. Das Verbindungsmittel 12 weist die Rohrhülse 13 auf dem Querträger 8 auf, mit dem das dreiecksförmige Trägerelement 9 verschraubt ist. In diesem Ausführungsbeispiel ist das dreiecksförmige Trägerelement 9 eines Medium"-Segments 3 der Fig. 1, dargestellt, das in einem flacheren Winkel gegenüber der Horizontalen angeordnet ist. Dadurch ergibt sich eine mittlere Aufbauhöhe der Rahmenstruktur 4 in der Fig. 1.The Figure 2b shows a further detailed side view of a connecting means 12 with a triangular carrier element. The connecting means 12 has the tubular sleeve 13 on the cross member 8, to which the triangular carrier element 9 is screwed. In this exemplary embodiment, the triangular carrier element 9 of a medium "segment 3 is the Fig. 1 , shown, which is arranged at a shallower angle with respect to the horizontal. This results in an average structural height of the frame structure 4 in the Fig. 1 .

Die Fig. 3a zeigt Beispiele mithilfe des erfindungsgemäßen Systems gebildeter Segmente 1 verschiedener Länge in perspektivischer Seitenansicht. Dabei handelt es sich um Ausführungsbeispiele von "Large"-Segmenten 5 mit großer Höhe der Rahmenstruktur 4. Bei allen drei Ausführungsformen von Segmenten 1 mit verschiedener Länge kommen dieselben dreiecksförmigen Trägerelemente 9, Querträger 8 sowie Verbindungsmittel 12 zum Einsatz. Es werden lediglich Profile 7, beispielsweise als Winkelbleche 14, in verschiedener Länge benötigt, um die Glättfläche 6 in der benötigten Länge auszubilden. Ebenso kommen entsprechend Obergurte 10 in unterschiedlichen Längen zum Einsatz. Dargestellt sind dabei von links nach rechts Segmente 1 mit zunehmender Gesamtlänge. Um für eine ausreichende Gesamtsteifigkeit der Rahmenstruktur 4 auch bei großer Länge zu sorgen, werden mit zunehmender Länge mehr dreiecksförmige Trägerelemente 9 eingesetzt. Dabei sind die an den Kopfseiten der Glättfläche 6 angesetzten dreiecksförmigen Trägerelemente 9 nach innen zu geneigt.The Fig. 3a shows examples of segments 1 of various lengths formed using the system according to the invention in a perspective side view. These are exemplary embodiments of "large" segments 5 with a great height of the frame structure 4. In all three embodiments of segments 1 with different lengths, the same triangular carrier elements 9, cross members 8 and connecting means 12 are used. Only profiles 7, for example as angle plates 14, of various lengths are required in order to form the smoothing surface 6 in the required length. Likewise, upper chords 10 of different lengths are used accordingly. Here, segments 1 with increasing overall length are shown from left to right. In order to ensure sufficient overall rigidity of the frame structure 4 even with a great length, more triangular support elements 9 are used with increasing length. The triangular support elements 9 attached to the head sides of the smoothing surface 6 are inclined inwards.

Vorteilhaft kann unter Verwendung eines zusätzlichen Querträgers 8 und dreiecksförmigen Trägerelements 9 sowie eines längeren Obergurtes 10 und längerer Profile 9 aus dem dargestellten Segment 1 der kürzesten Länge das mittlere Segment mit der mittleren Länge gebildet werden. Um aus diesem das Segment 1 der größten Länge, rechts dargestellt, zu bilden, sind zusätzlich zwei Querträger 8 und zwei dreiecksförmigen Trägerelemente 9 erforderlich sowie ein Obergurt 10 und Profile 7 entsprechender Länge. Mit nur wenigen zusätzlichen Bauteilen bzw. dem Austausch weniger Bauteile kann somit sehr flexibel durch das erfindungsgemäße System ein Segment 1 angepasst werden und insgesamt eine angepasste Rüttelbohle gebildet werden.Advantageously, the middle segment with the middle length can be formed from the illustrated segment 1 of the shortest length using an additional cross member 8 and triangular carrier element 9 as well as a longer top chord 10 and longer profiles 9. In order to form segment 1 of the greatest length, shown on the right, from this, two cross members 8 and two triangular carrier elements 9 are also required, as well as an upper flange 10 and profiles 7 of a corresponding length. With only a few additional components or the exchange of a few components, the system according to the invention can thus be very flexible Segment 1 can be adjusted and a total of an adjusted vibrating beam can be formed.

Die Fig. 3b zeigt weitere Beispiele mithilfe des erfindungsgemäßen Systems gebildeter Segmente 1 verschiedener Länge in perspektivischer Seitenansicht. Bei diesem Beispiel handelt es sich um "Medium"-Segmente 1, bei denen die dreiecksförmigen Trägerelemente 9 eine mittlere Höhe aufweisen. Die Rahmenstruktur 4 ist leichter aufgebaut und es sind weniger dreiecksförmige Trägerelemente 9 und Querträger 8 eingesetzt. Es können jedoch exakt die gleichen Profile 7 zur Bildung der Glättfläche 6 sowie die gleichen Obergurte 10 eingesetzt werden, wie bei dem Ausführungsbeispiel der Fig. 3a. Durch das erfindungsgemäße System wird es möglich, aus den in der Fig.3a dargestellten Segmenten 1 die hier dargestellten Segmente 1 zu bilden, indem lediglich weniger und abweichende dreiecksförmige Trägerelemente 9 eingesetzt werden, bei ansonsten gleichen Bauelementen.The Figure 3b shows further examples of segments 1 of different lengths formed using the system according to the invention in a perspective side view. This example involves “medium” segments 1 in which the triangular support elements 9 have a medium height. The frame structure 4 has a lighter structure and fewer triangular support elements 9 and cross members 8 are used. However, exactly the same profiles 7 can be used to form the smoothing surface 6 and the same upper chords 10 as in the embodiment of FIG Fig. 3a . The system according to the invention makes it possible, from the Fig.3a the segments 1 shown here to form the segments 1 shown here by only using fewer and different triangular carrier elements 9, with otherwise identical components.

Die Fig. 3c zeigt weitere Beispiele mithilfe des erfindungsgemäßen Systems gebildeter Segmente 1 verschiedener Länge in perspektivischer Seitenansicht in der Ausführungsform von "Small"-Segmenten 2. Die "Small"-Segmente 2 weisen keine Rahmenstruktur auf und die Glättfläche 6 ist aus den Profilen 7 und den Querträgern 8 gebildet. Dadurch können diese Segmente 1 allein mit den Bauteilen der zuvor in den Fig. 3a und Fig. 3b beschriebenen Segmente 1 innerhalb des Systems gebildet werden.The Figure 3c shows further examples of segments 1 of different lengths formed with the aid of the system according to the invention in a perspective side view in the embodiment of "small" segments 2. The "small" segments 2 have no frame structure and the smoothing surface 6 is made up of the profiles 7 and the cross members 8 educated. This allows these segments 1 alone with the components of the previously in the Figures 3a and 3b segments 1 described are formed within the system.

Die Fig. 4 zeigt eine erfindungsgemäße Rüttelbohle 15, die aus vier Segmenten 1 und einem Zugsegment 16 sowie weiteren Bauteilen aufgebaut ist. Von den vier Segmenten 1 sind zwei Segmente "Large"-Segmente 5, eines ein "Medium"-Segment 3 und eines ein "Small"-Segment 2. Jedes der Segmente 1 weist einen Vibrator 17 in Form eines Elektromotorvibrators 18 auf, der jeweils auf einem Querträger 8 direkt an der zusammen mit den Profilen 7 gebildeten Glättfläche 6 angeordnet ist.The Fig. 4 shows a vibrating screed 15 according to the invention, which is made up of four segments 1 and a tension segment 16 and other components. Of the four segments 1, two segments are “large” segments 5, one is a “medium” segment 3 and one is a “small” segment 2. Each of the segments 1 has a vibrator 17 in the form of an electric motor vibrator 18, each of which is arranged on a cross member 8 directly on the smoothing surface 6 formed together with the profiles 7.

Das linke der dargestellten "Large"-Segmente 5 weist eine Glättfläche 6 mit einer Lücke 19 auf. Dadurch kann beispielsweise die Rüttelbohle 15 auf einer zu fertigenden Betonoberfläche ohne Unterbrechung über hervorstehende Elemente, wie etwa Entwässerungsrohre, hinweg bewegt werden. Ermöglicht wird die Lücke 19, indem die dreiecksförmigen Trägerelemente 9 der Rahmenstruktur 4 durch Längsverbinder 20 oberhalb der Ebene der Glättfläche 6 verbunden sind. Durch Profilverlängerungen kann die Breite der Lücke 19 genau eingestellt werden.The left of the “large” segments 5 shown has a smoothing surface 6 with a gap 19. In this way, for example, the vibrating screed 15 can be moved over protruding elements, such as drainage pipes, on a concrete surface to be produced without interruption. The gap 19 is made possible by the triangular carrier elements 9 of the frame structure 4 by longitudinal connectors 20 are connected above the level of the smooth surface 6. The width of the gap 19 can be precisely adjusted by means of profile extensions.

Das Zugsegment 16 ist mit dem benachbarten "Large"-Segment 5 und dessen Rahmenstruktur 4 über Oberverbinder 22 verbunden, die längseinstellbar sind, indem eine Gewindehülse 23 über zwei Gewindestangen 24 geschraubt ist. Dadurch kann zwischen dem Zugsegment 16 und dem benachbarten "Large"-Segment 5 ein Winkel eingestellt werden, indem die Verbindungsmittel 12 in Form einer Rohrhülse 13 auf Höhe der Glättfläche 6 eine Verdrehung um einen Winkel ermöglichen.The tension segment 16 is connected to the adjacent “large” segment 5 and its frame structure 4 via upper connectors 22, which can be adjusted lengthways by screwing a threaded sleeve 23 over two threaded rods 24. As a result, an angle can be set between the tension segment 16 and the adjacent “large” segment 5 in that the connecting means 12 in the form of a tubular sleeve 13 at the level of the smoothing surface 6 allow a rotation by an angle.

Ebenso sind auch die weiteren Segmente 1 über Oberverbinder 22 miteinander verbunden. Dabei erstreckt sich in dem hier dargestellten Ausführungsbeispiel einer aus dem System gebildeten Rüttelbohle 15 ein Obergurt 10 mit zwei Oberverbindern 22 über das "Small"-Segment 2 hinweg. Das "Small"-Segment 2 ist dabei mit seinen Nachbarelementen über Vierlochplatten 33 mit den Profilen 7 der Nachbarsegmente direkt verschraubt und steif verbunden, da hier kein Winkel erforderlich ist. Dies ist generell zwischen den Segmenten 1 möglich, um eine möglichst steife Ausführung zu erreichen zwischen den Segmenten 1. Es ist auch denkbar, eine Vierlochplatte 33 vorzusehen, die einen festen und über eine steife Verbindung eingestellten Winkel zwischen zwei Segmenten ermöglicht. Dies ist insbesondere sinnvoll bei häufig vorkommenden, erforderlichen Winkelwerten.The other segments 1 are also connected to one another via top connectors 22. In the exemplary embodiment shown here, of a vibrating screed 15 formed from the system, an upper chord 10 with two upper connectors 22 extends over the “small” segment 2. The "small" segment 2 is directly screwed and rigidly connected to its neighboring elements via four-hole plates 33 with the profiles 7 of the neighboring segments, since no angle is required here. This is generally possible between the segments 1 in order to achieve the stiffest possible design between the segments 1. It is also conceivable to provide a four-hole plate 33 which enables a fixed angle between two segments that is set via a rigid connection. This is particularly useful in the case of required angle values that occur frequently.

Kurzsegmente 25, die aus einem Querträger 8 und zwei Verbindungsmitteln 12 in Form einer Rohrhülse 13 gebildet sind, ermöglichen eine genaue zusätzliche Anpassung der Breite der Rüttelbohle 15.Short segments 25, which are formed from a cross member 8 and two connecting means 12 in the form of a tubular sleeve 13, enable the width of the vibrating screed 15 to be precisely adjusted.

Die Fig. 4 zeigt weiterhin auch noch ein Führungselement 26 mit zwei Handgriffen mit denen die Rüttelbohle 15 durch einen Arbeiter bewegt werden kann. An dem Führungselement 26 ist auch ein Verlängerungselement 28 angeordnet, durch das eine Glättfläche 6 gebildet wird bis zu der gewünschten Arbeitsbreite der Rüttelbohle 15.The Fig. 4 also shows a guide element 26 with two handles with which the vibrating screed 15 can be moved by a worker. An extension element 28 is also arranged on the guide element 26, by means of which a smoothing surface 6 is formed up to the desired working width of the vibrating screed 15.

Die Fig. 5 zeigt das Verlängerungselement 28 der Fig. 4 als Einzelelement. Vor allem bei dem Führungselement 26, das am Rand der Rüttelbohle 15 eingebaut wird, ist es oft vorteilhaft, durch das Verlängerungselement 28 einen nochmals über das Führungselement 26 hinausreichenden Arbeitsbereich zu erhalten. Insbesondere kann damit auf Baustellen, bei denen am Rand Hindernisse vorliegen, wie beispielsweise eine Leitplanke oder ein Zaun bei einer Autobahn oder bei einem zu bildenden Brückenbauwerk eine Absturzsicherung, eine Rüttelbohle 15 erstellt werden, mit der in einem Arbeitsgang die gesamte Breite bearbeitet werden kann.The Fig. 5 shows the extension member 28 of FIG Fig. 4 as a single element. Especially in the case of the guide element 26, which is installed on the edge of the vibrating screed 15, it is often advantageous to use the extension element 28 to provide a further over the To get guide element 26 reaching beyond the work area. In particular, it can be used on construction sites where there are obstacles at the edge, such as a guardrail or a fence on a motorway or a bridge structure to be formed, a vibration beam 15 can be created with which the entire width can be processed in one operation.

Die Fig. 6 stellt einen Vibrator 17 dar, der als Elektromotorvibrator 18 ausgebildet ist und daher keine äußeren beweglichen Teile aufweist. Der Elektromotorvibrator 18 ist auf einem Querträger 8 angeordnet, der beidseitig mit den hier nicht dargestellten Profilen 7 zur Ausbildung einer Glättfläche 6 in den vorherigen Figuren verschraubt werden kann. Dadurch werden die Vibrationen direkt auf die Glättfläche 6 übertragen.The Fig. 6 shows a vibrator 17 which is designed as an electric motor vibrator 18 and therefore has no external moving parts. The electric motor vibrator 18 is arranged on a cross member 8, which can be screwed on both sides to the profiles 7, not shown here, to form a smooth surface 6 in the previous figures. As a result, the vibrations are transmitted directly to the smoothing surface 6.

Die Fig. 7 zeigt einen Querträger 8 mit den Verbindungsmitteln 12 in Form der Rohrhülse 13 und dem Oberverbinder 22. Der Oberverbinder 22 besteht aus der Gewindehülse 23, die über die zwei Gewindestangen 24 geschraubt ist. Ein Halter 29 ist an dem Querträger 8 befestigt und dient zur Montage des Oberverbinders 22. In der hier erfolgten Darstellung sind neben dem Querträger 8 auch noch Teile der Profile 7 dargestellt. Wenn ein Segment aus dem erfindungsgemäßen System ohne eine Rahmenstruktur gebildet wird, beispielsweise als das zuvor beschriebene "Small"-Segment 2, kann durch die hier dargestellte Anordnung mit dem Halter 29 eine längsverstellbare Verbindung mit einem seiner Nachbarsegment über den Oberverbinder 22 erfolgen und zusammen mit den Verbindungsmitteln 12 auch hier eine feste, um einen Winkel einstellbare Verbindung zum Nachbarsegment erfolgen.The Fig. 7 shows a cross member 8 with the connecting means 12 in the form of the tubular sleeve 13 and the top connector 22. The top connector 22 consists of the threaded sleeve 23 which is screwed over the two threaded rods 24. A holder 29 is attached to the cross member 8 and is used to assemble the upper connector 22. In the illustration made here, in addition to the cross member 8, parts of the profiles 7 are also shown. If a segment is formed from the system according to the invention without a frame structure, for example as the "small" segment 2 described above, a longitudinally adjustable connection with one of its neighboring segments via the upper connector 22 and together with the holder 29 can be made through the arrangement shown here the connecting means 12 here also have a fixed connection to the neighboring segment that is adjustable by an angle.

Die Fig. 8 zeigt ein Kurzsegment 25, das aus dem Querträger 8 und den zwei Verbindungsmitteln 12 in Form einer Rohrhülse 13 gebildet ist. Bei dem hier dargestellten Ausführungsbeispiel ist der Querträger 8 mit den Rohrhülsen 13 über Schweißnähte verbunden.The Fig. 8 shows a short segment 25, which is formed from the cross member 8 and the two connecting means 12 in the form of a tubular sleeve 13. In the exemplary embodiment shown here, the cross member 8 is connected to the tubular sleeves 13 via weld seams.

Die Fig. 9 zeigt im Detail den Querträger 8 mit den aufgeschraubten Verbindungsmitteln 12 in Form einer Rohrhülse 13. Bei diesem Ausführungsbeispiel wird die Gesamteinheit in dem System aus den Einzelelementen des Querträgers 8 und der Rohrhülse 13 durch Verschraubung aus Einzelelementen gebildet.The Fig. 9 shows in detail the cross member 8 with the screwed-on connecting means 12 in the form of a tubular sleeve 13. In this embodiment, the entire unit in the system is formed from the individual elements of the cross member 8 and the tubular sleeve 13 by screwing individual elements.

Die Fig. 10 zeigt die Verbindungsmittel 12 der Fig. 9 im Detail mit der Rohrhülse 13.The Fig. 10 shows the connecting means 12 of FIG Fig. 9 in detail with the pipe sleeve 13.

Die Fig. 11 zeigt das dreiecksförmige Trägerelement 9 einer hohen Ausführung der Rahmenstruktur 4 in einer der vorhergehenden Zeichnungen zur Bildung eines "Large"-Segments 5. Das dreieckförmige Trägerelement 9 ist dabei auf den Querträger 8 aufgeschraubt, auf den zusätzlich das Verbindungsmittel 12 aufgeschraubt ist, wie es in Figur. 10 dargestellt ist.The Fig. 11 shows the triangular carrier element 9 of a high version of the frame structure 4 in one of the preceding drawings to form a "large" segment 5. The triangular carrier element 9 is screwed onto the cross member 8, onto which the connecting means 12 is also screwed, as shown in FIG Figure. 10 is shown.

Die Fig. 12 zeigt einen Querträger 8 mit den Verbindungsmitteln 12 in Form der Rohrhülse 13 sowie den Halter 29, an dem ein Oberverbinder 22 montiert werden kann.The Fig. 12 shows a cross member 8 with the connecting means 12 in the form of the tubular sleeve 13 and the holder 29, on which a top connector 22 can be mounted.

Die Fig. 13 zeigt eine "Handpatsche" 30 die aus einem "Small"-Segment 2 mit der Glättfläche 6 aus den Profilen 7 und den an den Kopfseiten angeordneten Querträgern 8 sowie dem Vibrator 17 besteht. An einem der Profile 7 ist ein Handgriff 31 mit Gelenken 32 angebracht und ermöglicht es, das "Small"-Segment 2 als Handpatsche 30 per Hand über eine Betonoberfläche zu bewegen. Dadurch ermöglicht es das System auch flexibel, sich eine in Steifigkeit bzw. Arbeitsbreite angepasste Handpatsche 30 zu erstellen, da der Handgriff 31 auch an "Medium"-Segmenten 3 und "Large"-Segmenten 5 unterschiedlicher Breiten angeordnet werden kann.The Fig. 13 shows a "hand tool" 30 which consists of a "small" segment 2 with the smoothing surface 6 of the profiles 7 and the cross members 8 and the vibrator 17 arranged on the head sides. A handle 31 with joints 32 is attached to one of the profiles 7 and makes it possible to move the "small" segment 2 as a handle 30 by hand over a concrete surface. As a result, the system also makes it possible to flexibly create a handle 30 adapted in terms of stiffness or working width, since the handle 31 can also be arranged on "medium" segments 3 and "large" segments 5 of different widths.

Die Fig. 14 zeigt den Bereich der Verbindung zweier Segmente 1 durch die Verbindungsmittel 12 mit jeweiliger Rohrhülse 13 und einem eingesetzten Bolzen sowie darüber angeordneten Oberverbinder 22. In dem hier dargestellten Beispiel sind zwei Oberverbinder 22 angeordnet und besteht eine doppelte Verbindung mit der Folge einer größeren Steifigkeit und Festigkeit. Die Oberverbinder bestehen jeweils aus einer Gewindehülse 23, in die beidseits eine Gewindestange 24 eingeschraubt ist. Bei dem hier dargestellten Ausführungsbeispiel werden die Rahmenstrukturen 4 der beiden Segmente 1 durch einen Oberverbinder 22 verbunden, der zwischen den Obergurten 10 angeordnet ist. Zusätzlich verbindet ein weiterer Oberverbinder 22 zusätzliche Halter 29, die auf die Obergurte 10 aufgesetzt sind.The Fig. 14 shows the area of the connection of two segments 1 by the connecting means 12 with the respective pipe sleeve 13 and an inserted bolt as well as overhead connector 22. In the example shown here, two overhead connectors 22 are arranged and there is a double connection with the result of greater rigidity and strength. The top connectors each consist of a threaded sleeve 23 into which a threaded rod 24 is screwed on both sides. In the embodiment shown here, the frame structures 4 of the two segments 1 are connected by an upper connector 22 which is arranged between the upper chords 10. In addition, a further upper connector 22 connects additional holders 29 which are placed on the upper chords 10.

Völlig unabhängig von dem hier dargestellten konkreten Ausführungsbeispiel des Aufbaus der Segmente 1 ist es auch denkbar, eine solche doppelte Verbindung bei anderen Ausführungsform einzusetzen, die nicht den hier dargestellten Aufbau mit einem Obergurt 10 und einem dreiecksförmigen Trägerelement 9 aufweisen. Es müssen einzig und allein zwei Oberverbinder 22 jeweils mit dem einen Segment und dem anderen Segment verbunden werden.Completely independent of the specific exemplary embodiment of the structure of the segments 1 shown here, it is also conceivable to use such a double connection in other embodiments that do not have the structure shown here with an upper belt 10 and a triangular support element 9. It only two top connectors 22 have to be connected to one segment and the other segment.

Die Fig. 15 zeigt ein weiteres Beispiel einer Rüttelbohle 15. Die Rüttelbohle 15 ist in dem hier vorliegenden Beispiel aus neun Segmenten 1 aufgebaut, bei denen es sich um Segmente mittlerer Höhe oder "Medium"-Segmente 3 handelt. An beiden Seiten der Rüttelbohle 15 sind Zugsegmente 16 angeordnet, die bei dem hier vorliegenden Ausführungsbeispiel anmontierte Rollen 34 aufweisen, auf denen die Rüttelbohle 15 über Führungsschienen geführt werden kann. Die Segmente 1 weisen untereinander mehrfach kleine Winkel auf, sodass die Glättflächen 6 insgesamt eine Bogenform bilden, wie sie beispielsweise in einem Tunnelboden bearbeitet werden muss. Jedes der Zugsegmente 16 weist eine Seilrolle 35 auf, auf die jeweils ein Stahlseil aufgewickelt werden kann. Durch das Aufwickeln dieser an nicht dargestellten Zugpunkten befestigten Stahlseile auf die Seilrollen 35 wird die Rüttelbohle 15 über die zu bearbeitende Oberfläche gezogen, beispielsweise eine Betonoberfläche.The Fig. 15 shows a further example of a vibrating screed 15. In the present example, the vibrating screed 15 is made up of nine segments 1, which are segments of medium height or “medium” segments 3. On both sides of the vibrating screed 15, tension segments 16 are arranged, which in the present exemplary embodiment have rollers 34 mounted on them, on which the vibrating screed 15 can be guided over guide rails. The segments 1 have multiple small angles with one another, so that the smoothing surfaces 6 as a whole form an arc shape, such as has to be processed in a tunnel floor, for example. Each of the pull segments 16 has a rope pulley 35, onto which a steel rope can be wound. By winding these steel cables fastened at traction points (not shown) onto the pulleys 35, the vibrating beam 15 is pulled over the surface to be processed, for example a concrete surface.

In dem hier dargestellten Ausführungsbeispiel werden die Seilrollen 35 durch einen rechten elektrischen Zugmotor 36 und einen linken elektrischen Zugmotor 37 jeweils angetrieben. Die Zugmotoren 36, 37 werden dabei über einen Umrichter angesteuert.In the exemplary embodiment shown here, the rope pulleys 35 are each driven by a right electric pull motor 36 and a left electric pull motor 37. The traction motors 36, 37 are controlled via a converter.

Dies ermöglicht es vorteilhaft, die Zugmotoren 36, 37 in einem Verfahren zu betreiben, durch das die Rüttelbohle 15 gleichmäßig angetrieben bzw. quer zu ihrer Arbeitsrichtung exakt ausgerichtet werden kann. So können die beiden Zugmotoren 36, 37 über einen einzigen Umrichter gemeinsam angesteuert werden. Dadurch ist die Drehzahl exakt synchron und die Rüttelbohle 15 wird auf der rechten und linken Seite mit genau der gleichen Geschwindigkeit gezogen. Sowohl beim Anlaufen wie auch im Normalbetrieb wird dadurch die vor Inbetriebnahme quer zur Arbeitsrichtung ausgerichtete Rüttelbohle 15 exakt geführt und es besteht nur eine geringe Gefahr, dass die Rüttelbohle 15 ihre Ausrichtung verliert.This advantageously makes it possible to operate the traction motors 36, 37 in a method by which the vibrating screed 15 can be driven uniformly or precisely aligned transversely to its working direction. The two traction motors 36, 37 can thus be controlled jointly via a single converter. As a result, the speed is exactly synchronized and the vibrating screed 15 is pulled on the right and left side at exactly the same speed. Both during start-up and in normal operation, the vibrating screed 15, which is aligned transversely to the working direction before start-up, is precisely guided and there is only a slight risk that the vibrating screed 15 will lose its alignment.

Sollte dennoch ein unerwünschter Winkel auftreten und die Rüttelbohle 15 neu ausgerichtet werden müssen, so kann durch elektrische Schalter vorgesehen sein, dass zeitweilig einer der beiden Zugmotoren 36, 37 von dem Umrichter getrennt wird. Dadurch kann eine nacheilende Seite so lange allein gezogen werden, bis die Rüttelbohle 15 wieder exakt quer zu ihrer Arbeitsrichtung ausgerichtet ist. Sobald Letzteres erreicht ist, werden wieder beide Zugmotoren 36, 37 auf den einen Umrichter geschaltet.Should an undesirable angle nevertheless occur and the vibrating screed 15 have to be realigned, electrical switches can be used to temporarily disconnect one of the two traction motors 36, 37 from the converter. As a result, a trailing side can be pulled alone until the vibrating screed 15 is again aligned exactly transversely to its working direction. As soon as The latter is achieved, both traction motors 36, 37 are switched to the one converter again.

Die in der Fig. 15 beschriebene Ausführungsform einer Rüttelbohle 15 mit zwei Zugmotoren 36, 37 kann bei den zuvor beschriebenen Beispielen von Rüttelbohlen 15, die aus einem System gebildet werden, zum Einsatz kommen. Es ist jedoch auch möglich, völlig unabhängig von den zuvor beschriebenen Merkmalen und Elementen des Systems bei jeglicher Art von Rüttelbohlen die hier beschriebenen Merkmale zweier Zugmotoren 36, 37 und das Verfahren deren Ansteuerung über einen einzigen Umrichter vorzusehen. Die Zugmotoren 36, 37 können dabei sowohl Synchron-, als auch Asynchronmotoren sein und es können auch mehr als zwei Zugmotoren 36, 37 zum Einsatz kommen, wenn weitere Zugsegmente 16 vorgesehen werden. In letzterem Fall können diese jeweils einzeln oder in Gruppen auf den einen Umrichter zugeschaltet werden oder von diesem getrennt werden.The ones in the Fig. 15 described embodiment of a vibrating screed 15 with two traction motors 36, 37 can be used in the previously described examples of vibrating screeds 15 that are formed from a system. However, it is also possible, completely independent of the previously described features and elements of the system, to provide the features of two traction motors 36, 37 described here and the method of controlling them via a single converter for any type of vibrating screed. The pulling motors 36, 37 can be both synchronous and asynchronous motors and more than two pulling motors 36, 37 can also be used if further pulling segments 16 are provided. In the latter case, these can be connected to or separated from one converter individually or in groups.

Selbstverständlich ist das hier beschriebene Verfahren und die Verwendung von mindestens zwei Zugmotoren 36, 37 auch völlig unabhängig davon, ob die Rüttelbohle 15 eine bogenförmige Form, wie hier dargestellt hat, und ob Rollen 34 für Führungsschienen vorgesehen sind.Of course, the method described here and the use of at least two traction motors 36, 37 is also completely independent of whether the vibrating beam 15 has an arcuate shape, as shown here, and whether rollers 34 are provided for guide rails.
