Die Erfindung betrifft ein Gerüst gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a scaffold according to the preamble of Claim 1.

Höhenverstellbare Arbeitsgerüste, beispielsweise in Form eines Flächengerüstes mit Kurbelverstellung einer Lastenbühne sind bekannt.Height-adjustable scaffolding, for example in the form of a Scaffolding with crank adjustment of a load platform are known.

Bei derartigen Kurbelbühnen ist in einem Bockrahmen ein höhenverstellbares Element nach Art einer Teleskopführung angeordnet. Das höhenverstellbare Element wird mit einer Kurbel, die mit einer Achse zusammenwirkt, angetrieben. Hierfür besitzt das höhenverstellbare Element beabstandete Aussparungen, in die ein Zahnrad auf der Achse des Antriebselementes eingreift. Für jedes Element ist ein Antriebsmechanismus erforderlich, und die Höhenverstellung kann nur manuell ohne Lastauflage vorgenommen werden, so daß beispielsweise bei Verwendung einer derartigen Kurbelbühne zum Errichten einer Mauer der Arbeitsprozeß mehrfach unterbrochen werden muß.In such crank stages is in a trestle frame Height-adjustable element like a telescopic guide arranged. The height-adjustable element comes with a Crank, which cooperates with an axis, driven. Therefor the height-adjustable element has spaced apart Cutouts in which a gear wheel on the axis of the drive element intervenes. There is a drive mechanism for each element required, and the height adjustment can only can be done manually without load support, so that for example when using such a crank platform for Building a wall interrupted the work process several times must become.

Aus dem deutschen Gebrauchsmuster DE-U-94 01 407 ist ein gattungsbildender höhenverstellbarer Gerüstbock mit unterem Rohrrahmen und einem ausziehbaren Oberteil bekannt, wobei die Höhenverstellung selbst durch einen Hydraulikzylinder/kolben erfolgt. Der erforderliche Hydraulikzylinder ist in die Rahmenkonstruktion integriert und wird von einem externen Aggregat angetrieben, so daß auch eine Höhenverstellung unter Last möglich ist. Weiterhin ist an der Rahmenkonstruktion ein Rad angeordnet, so daß der jeweilige Bock leicht manuell an einen anderen Standort transportiert werden kann. Zusätzlich ist am Gerüstbock ein abklappbarer Geländerholm befestigt und eine höhenverstellbare Arbeitsbühne vorgesehen. From the German utility model DE-U-94 01 407 is a generic height-adjustable trestle with lower Tubular frame and a pull-out top known, the Height adjustment even by a hydraulic cylinder / piston he follows. The required hydraulic cylinder is in the Integrated frame construction and is from an external Unit driven, so that a height adjustment under Load is possible. Furthermore, is on the frame construction Wheel arranged so that the respective trestle easily manually can be transported to another location. additionally a folding railing rail is attached to the scaffold frame and a height-adjustable work platform is provided.

Mittels dem im deutschen Gebrauchsmuster DE-U-94 01 407 gezeigten höhenverstellbaren Gerüstbock kann zwar eine Verstellung unter Last vorgenommen werden, jedoch erfordert das Höhenverstellen einer ausgedehnten Arbeitsfläche entlang eines zu errichtenden Mauerwerkes zum Erhalten einer möglichst exakten waagerechten Lage viel Zeitaufwand und Geschick beim Betätigen bzw. Ansteuern der einzelnen Hydraulikzylinder. Darüber hinaus hat sich gezeigt, daß das bekannte Transportrad zwar zur wesentlichen Erleichterung bei der Lageveränderung dient, jedoch aufgrund des gegebenen Schwerpunktes ein Verkippen oder Wegkippen des Gerüstbockes auftritt, wodurch die Arbeitssicherheit beim Transport gefährdet ist.By means of that shown in the German utility model DE-U-94 01 407 Height-adjustable scaffold frame can be adjusted under Load must be made, however, height adjustment is required an extensive work surface along one to be erected Masonry to get the most exact horizontal possible Location a lot of time and skill when operating or Actuation of the individual hydraulic cylinders. It also has It has been shown that the well-known transport bike for makes it much easier to change the location, however, due to the given center of gravity, tilting or Tilting away of the trestle occurs, causing the Occupational safety during transport is at risk.

Weiterhin ist aus der EP-A-0 206 382 die Ausbildung von Lasthalteventilen bekannt, die in Hydraulikkreisen Verwendung finden.Furthermore, EP-A-0 206 382 describes the formation of Load holding valves are known to be used in hydraulic circuits Find.

Es ist daher Aufgabe der Erfindung, ein Gerüst, umfassend Gerüstböcke mit hydraulischer Höhenverstellung der bekannten Art derart weiterzuentwickeln, daß die Arbeitssicherheit und die Arbeitsproduktivität bei Anwendung eines derartigen Gerüsts erhöht wird und daß die Bedienung beim Aufstellen und der Höhenverstellung möglichst vereinfacht werden kann.It is therefore an object of the invention to include a scaffold Trestles with hydraulic height adjustment of the well-known Art to develop in such a way that occupational safety and labor productivity when using such a scaffold is increased and that the operation when setting up and Height adjustment can be simplified as possible.

Die Lösung der Aufgabe der Erfindung erfolgt mit einem Gegenstand gemäß dem Patentanspruch 1, wobei die Unteransprüche zweckmäßige Ausgestaltungen und Weiterbildungen umfassen.The object of the invention is achieved with a Subject according to claim 1, the subclaims include expedient refinements and developments.

Das Gerüst wird so eingesetzt, daß eine Vielzahl, jedoch mindestens zwei Gerüstböcke beabstandet angeordnet sind, so daß eine quasi beliebige Lasten- und Arbeitsfläche jeweils vorgegebener gleicher Arbeitshöhe entsteht. Die Arbeitshöhe ist kontinuierlich und gleichmäßig auch unter Last und fernbedient einstellbar, indem die jeweiligen Hydraulikzylinder der Vielzahl von Gerüstböcken mittels eines Hydraulikaggregates angesteuert werden, das einen Zahnradmengenteiler zur gleichmäßigen Druck- bzw. Hydraulikflüssigkeitsbeaufschlagung aufweist. Zusätzlich besitzen die Hydraulikzylinder jeweils ein Lasthalteventil, so daß auch nach Abschalten oder Entfernen des Hydraulikaggregates die jeweilige gewählte, momentane Arbeitshöhe erhalten bleibt.The scaffold is used so that a large number, but at least two scaffolding frames are arranged so that a virtually arbitrary load and work surface each predetermined same working height. The working height is continuously and evenly under load and remotely operated adjustable by the respective hydraulic cylinder of the variety controlled by trestles by means of a hydraulic unit become a gear divider for even Has pressure or hydraulic fluid loading. In addition, the hydraulic cylinders each have a load holding valve, so that even after switching off or removing the Hydraulic power pack the selected, current working height preserved.

Mittels des Zahnradmengenteilers wird gewährleistet, daß jeweils die gleiche vorgegebene Hydraulikflüssigkeitsmenge bei entsprechend identisch dimensionierten Hydraulikzylindern auf die jeweiligen Hydraulikkolben einwirkt, so daß im vorgegebenen Maße eine gleichmäßige Höhenverstellung eines Lastenbühnenträgers gegeben ist.By means of the gear meter, it is ensured that each with the same predetermined amount of hydraulic fluid correspondingly dimensioned hydraulic cylinders the respective hydraulic piston acts so that in the predetermined Dimensions an even height adjustment of a load platform given is.

Hierdurch ist das ansonsten erforderliche manuelle Einstellen der Höhe einer Vielzahl von Gerüstböcken bei großen Arbeitsflächen nicht notwendig.This makes manual adjustment otherwise required the height of a large number of scaffolding trestles for large work surfaces unnecessary.

Zum Höhenausgleich z.B. bei Unregelmäßigkeiten des Aufstellbodens ist auch eine einzelne Ansteuerung der jeweiligen Hydraulikzylinder gewährleistet.For height compensation e.g. in the event of irregularities in the installation floor is also a single control of the respective Hydraulic cylinder guaranteed.

Das bekannte Transportrad ist zur Vermeidung seitlichen Verkippens bei Lageveränderungen des Gerüstbockes als Doppelrad ausgebildet, welches auf einer gemeinsamen Achse angeordnet ist.The well-known transport wheel is to avoid lateral tilting when changing the position of the trestle as a double wheel formed, which is arranged on a common axis is.

Im Interesse einer optimalen Arbeitssicherheit besitzt der Lastenbühnenträger Mittel zum Aufnehmen eines klappbaren Sicherheitsgeländers, wobei im Transport bzw. abgeklappten Zustand das Sicherheitsgeländer am Rahmenholm fixiert ist und Teile desselben gleichzeitig einen Transportgriff zur leichteren Lageveränderung des Gerüstbockes mittels des Doppelrades bilden.In the interest of optimal occupational safety, the Load platform support means for holding a foldable Safety railing, being in transport or folded down Condition that the safety railing is fixed to the frame rail and Parts of the same a transport handle for easier Change of position of the trestle using the double wheel form.

Durch am Lastenträger arretiert aufsteck- und auswechselbare Adapterauflagen kann in vorteilhafter Weise ein seitliches Fixieren und Aufnehmen ganz unterschiedlicher Belagrahmen erfolgen, ohne daß kostenintensive Veränderungen am Gerüstbock selbst notwendig sind. Interchangeable and interchangeable on the load carrier Adapter pads can advantageously be a side Fixing and holding very different covering frames done without costly changes to the trestle themselves are necessary.

Das klappbare Sicherheitsgeländer weist einen Arretierungsbügel auf, der in dem Falle, daß das Geländer sich in seiner eigentlichen Funktionsstellung befindet, zusätzlich den Belagrahmen und/oder den dort befindlichen Belag gegen höhenmäßiges Verkippen sichert.The foldable safety railing has a locking bracket on, in the event that the railing is in its actual Functional position is in addition, the covering frame and / or the covering there against height Tilting secures.

In einer Ausführungsform der Erfindung ist der jeweilige Hydraulikzylinder des jeweiligen Gerüstbockes nahezu mittig auf einem unteren Rahmenquerträger angeordnet und am oberen Rahmenquerträger geführt, so daß mittels eines einzigen Hydraulikzylinders ein teleskopartiges Ein- und Ausfahren des Lastenbühnenträgers, der in den Rahmenholmen beweglich geführt ist, erfolgen kann.In one embodiment of the invention, the respective Hydraulic cylinder of the respective trestle almost in the middle arranged a lower frame cross member and on the upper Frame cross member guided so that by means of a single Hydraulic cylinder a telescopic retraction and extension of the Load platform carrier, which is movably guided in the frame bars is can be done.

Zum ungestörten Höhenverstellen ist der Hydraulikkolben am Lastenbühnenträger gelenkig angeschlagen, so daß ein Verkanten der Teleskopführungen, insbesondere beim Einfahren des Lastenbühnenträgers, nahezu ausgeschlossen ist.The hydraulic piston is on for undisturbed height adjustment Load platform girder hinged, so that tilting the telescopic guides, especially when retracting the load platform, is almost impossible.

Den Erfordernissen des Baubetriebes entsprechend sind die Hydraulikanschlußelemente am Zylinderboden im wesentlichen im Breitenbereich des unteren Rahmenquerträgers, durch diesen gegen mechanische Beschädigung geschützt, angeordnet. Erforderliche Hydraulikrohre sind enganliegend an der Außenumfangsfläche des Hydraulikzylinders vorgesehen, so daß Beschädigungen, insbesondere mechanischer Art, reduziert sind.According to the requirements of the construction company Hydraulic connection elements on the cylinder bottom essentially in Width range of the lower frame cross member, through this protected against mechanical damage, arranged. necessary Hydraulic pipes are tight-fitting on the outer peripheral surface of the hydraulic cylinder so that damage, especially mechanical, are reduced.

Zur Vermeidung von Verletzungen durch Einquetschen von Körperteilen, insbesondere des Kopfes oder des Rumpfes, wird im eingefahrenen, d.h. abgesenkten Zustand des Gerüstbockes ein Sicherheitsabstand zwischen Lastenbühnenträger und oberem Rahmenquerträger gewährleistet.To avoid injuries from crushing Parts of the body, especially the head or trunk, are in the retracted, i.e. lowered state of the trestle Safety distance between the load platform girder and the upper one Frame cross member guaranteed.

Dieser Sicherheitsabstand beträgt in einer vorteilhaften Ausführungsform im wesentlichen 20 cm.This safety distance is advantageous Embodiment essentially 20 cm.

Alles in allem ermöglichen die Gerüstböcke durch den speziellen Hydraulikzylinder mit im unteren Bereich angeordnetem Lasthalteventil ein Arretieren in beliebiger Höhe, auch in dem Falle, wenn ein Hydraulikaggregat nicht angeschlossen ist. Es ist demnach ein höhenmäßiges Arretieren in jeder Position unter allen Umständen sicherheitstechnisch gewährleistet.All in all, the scaffolding trestles are made possible by the special Hydraulic cylinder with load holding valve located in the lower area locking at any height, even in the Trap if a hydraulic unit is not connected. It is therefore a height locking in any position below guaranteed in all circumstances.

Durch das Transportrad, welches als Doppelrad ausgebildet ist, ist ein Wegkippen des Gerüstbockes beim Anheben und Wegschieben desselben bei einer Einmannbedienung ausgeschlossen.Through the transport wheel, which is designed as a double wheel, is a tilting of the trestle when lifting and pushing away the same with one-man operation excluded.

Das Sicherheitsgeländer, welches beispielsweise mit einem Befestigungsbolzen nach unten geklappt fixiert werden kann, ermöglicht die Nutzung von Teilen des Sicherheitsgeländers, nämlich der Mittel zum Einhängen von Geländerquerverstrebungen als Tragegriff. Dieser Tragegriff dient zum leichten Wegbewegen des einzelnen Bockes mittels der vorerwähnten Doppelräder. Darüber hinaus sind an der dem Rad abgewandten Längsstrebe Befestigungsvorrichtungen zur Anordnung von gegebenenfalls längenverstellbaren Querstreben, die die Böcke untereinander verbinden und gegen Rutschen sichern, vorgesehen. Die Längenverstellbarkeit ergibt die Möglichkeit, die Bockabstände zu verändern, wodurch sich die Belastbarkeit erhöht und Belagrahmen unterschiedlicher Abmessungen verwendet werden können.The security railing, which for example with a Fastening bolt can be fixed folded down enables the use of parts of the security railing, namely the means for hanging railing cross struts as a handle. This handle is for easy moving away of the single trestle by means of the aforementioned double wheels. In addition, on the longitudinal strut facing away from the wheel Fastening devices for the arrangement of if necessary length-adjustable cross struts that link the trestles to one another connect and secure against slipping, provided. The Adjustable length gives the possibility of the stand spacing to change, which increases the resilience and Covering frames of different dimensions can be used can.

Der Lastenbühnenträger besitzt im wesentlichen gegenüberliegend Bohrungen, die dem Arretieren von Adapterauflagen für unterschiedlichste Belagrahmen dienen. Die Adapterauflagen weisen im Querschnitt z.B. eine Dreiecks- oder eine halbrunde Form auf, so daß Belagrahmen bzw. Aufsatzrahmen unterschiedlichster Gerüsthersteller sicher gegen Wegrutschen arretierbar sind, ohne daß im eigentlichen Hydraulikbock irgendwelche konstruktiven Veränderungen vorgenommen werden müssen.The load platform carrier has essentially opposite Bores that lock the adapter supports for a wide variety Cover frames serve. The adapter pads have in Cross section e.g. a triangular or semicircular shape, so that covering frame or stacking frame of the most varied Scaffold manufacturers can be securely locked against slipping, without any constructive in the actual hydraulic frame Changes need to be made.

In einer Ausführungsform ist die obere Aufnahme des Hydraulikkolbens am oberen Rahmenträger so ausgeführt, daß ein U-förmiges Umgreifen des oberen Rahmenträgers realisiert wird. In one embodiment, the upper receptacle of the hydraulic piston on the upper frame support so that a U-shaped Reaching around the upper frame support is realized.

Hierdurch erhöht sich die Stabilität gegen seitliches Verkippen bei schräg einsetzenden Kräften von oben.This increases the stability against lateral tilting with oblique forces from above.

In einer weiteren Ausführungsform der Erfindung sind die Profile der teleskopartig ineinander steckenden Holme im wesentlichen quadratisch oder mit einem rechteckigen Querschnitt ausgebildet.In a further embodiment of the invention, the Profiles of the telescoping stiles in the essentially square or with a rectangular cross section educated.

Als besonderer Vorteil ergibt sich bei der Aufstellung mehrerer Gerüstböcke die Ausbildung einer großen Arbeitsfläche, die über Eck, andersartig winklig mit Zwischenstücken oder eine große zusammenhängende Fläche bildend ausgestaltbar ist.A particular advantage arises when several are installed Scaffolding the formation of a large work surface that over Corner, differently angled with spacers or a large one coherent surface can be configured.

Durch die Verwendung eines Hydraulikaggregates mit Zahnmengenteiler ist ein gleichmäßiges Anheben oder Absenken dieser letztendlich beliebig formbaren Fläche gewährleistet.By using a hydraulic unit with a tooth divider is an even raising or lowering of these ultimately guarantees any formable surface.

Zusätzlich ist der Gerüstbock auch zum Anheben von Trägern oder dergleichen hin zum Deckenbereich geeignet, ohne daß Kran- oder andere Hebevorrichtungen eingesetzt werden müssen.In addition, the scaffolding trestle is also for lifting beams or The like suitable for the ceiling area without crane or other lifting devices must be used.

Derartige andere Hebevorrichtungen können z.B. bei der Altbausanierung ohnehin nicht uneingeschränkt zur Anwendung gelangen, da bekannte Kräne oder Hydraulikarbeitsbühnen nicht in den bereits umbauten Raum hinein transportiert und aufgebaut werden können.Such other lifting devices can e.g. in the Old building renovation is not to be used without restrictions anyway because there are no known cranes or hydraulic work platforms transported and built into the already converted space can be.

Vorhandene Arretierungswinkel zur Aufnahme der Arbeitsbühne bzw. einer Lauffläche, welche auf der Arbeitsbühne aufliegt, sind so ausgebildet, daß eine Auskragung bzw. Nase, ebenso wie beim Sicherheitsgeländer, den Belagrahmen bzw. darauf befindliche Bretter sichert. Der Träger für die Arbeitsbühne selbst ist durch Lochrastung oder hydraulisch höhenverstellbar.Existing locking brackets to accommodate the work platform or a running surface that rests on the work platform, are designed so that a projection or nose, as well with the safety railing, the covering frame or on it secure boards. The carrier for the working platform itself can be adjusted in height by means of holes or hydraulically.

Die Steuerung einer Vielzahl von Hydraulikzylindern erfolgt gleichmäßig, wobei die Zylinder aber auch einzeln ansteuerbar sind, so daß ein Höhenausgleich, z.B. bei unterschiedlichem Untergrund, vorgenommen werden kann. A large number of hydraulic cylinders are controlled evenly, but the cylinders can also be controlled individually so that a height compensation, e.g. with different Underground, can be made.

Das verwendete Aggregat ist leicht ortsveränderlich und kann für die Steuerung mehrerer Gruppen von Hydraulikböcken bzw. den Hydraulikzylindern derartiger Böcke benutzt werden. Darüber hinaus ist das Aggregat fernbedienbar, so daß der Bauarbeiter, welcher sich auf dem Hydraulikbock arbeitend befindet, ferngesteuert den Bock bzw. die Böcke in der Höhe verändern kann.The unit used is easy to move and can for the control of several groups of hydraulic stands or the Hydraulic cylinders of such trestles are used. About that the unit can also be operated remotely so that the construction worker, which is working on the hydraulic jack, remotely change the height of the trestle or trestles can.

Wie erwähnt, fährt der Hydraulikbock nur bis auf eine vorgegebene Rasthöhe ein, so daß eine Gefährdung möglicherweise darunterstehender Personen ausgeschlossen ist.As mentioned, the hydraulic jack only moves to a predetermined one Rest height, so that a hazard may be persons below are excluded.

Die Hydraulikböcke selbst sind raumsparend, im wesentlichen tragbar und können mit einer Einmannbedienung auf- und abgebaut werden. Durch den leichten Transport können darüber hinaus Hebebühnen, die an bestimmten Orten nicht einsetzbar sind, ersetzt werden. Dies kann beispielsweise zweckmäßig sein, wenn Unterzugschalungen anzubringen sind oder nachträglich Träger eingebaut werden müssen.The hydraulic jacks themselves are essentially space-saving portable and can be assembled and disassembled with one-man operation become. Thanks to the easy transport, you can also Lifts that cannot be used in certain locations, be replaced. This can be useful, for example, if Beam formwork is to be installed or beams can be added later must be installed.
