Description
Die Erfindung betrifft ein Hubgerüst mit mehreren Gerüstmasten, die auf wenigstens einer Plattform stehen und schußweise verlängerbar sind, zwischen denen Fahrbühnen höhenveränderlich angeordnet sind, wobei die Gerüstmaste mittels mehrerer Haltestützen an der Gebäudefassade befestigt sind.The invention relates to a lifting scaffold with a plurality of scaffolding masts, which stand on at least one platform and can be extended in sections, between which elevating platforms are arranged at different heights, the scaffolding masts being fastened to the building facade by means of several holding supports.
Aus der DE-OS 35 26 105 ist ein Gerüst für Reparaturarbeiten an Fassaden und Dachtraufen bekannt, das eine begehbare Gerüstbrücke zwischen zwei fahrbaren Hubgerüsten aufweist, wobei die Gerüstbrücke in Arbeitshöhe auf dort angebrachten Laufschienen oder Traversen in Richtung Fassade verschiebbar ist.From DE-OS 35 26 105 a scaffold for repair work on facades and eaves is known, which has a walkable scaffold bridge between two mobile masts, the scaffold bridge at work height on rails or trusses attached there can be moved towards the facade.
In der DE-OS 31 14 602 ist eine Einrichtung für Arbeitsgerüste mit heb- und senkbarer Arbeitsbühne mit zugehöriger Sicherheitsvorrichtung beschrieben. Die Arbeitsbühne ist zwischen vier mit Aussparungen versehenen Führungsschienen angeordnet und an beiden Seiten über einen Hubmechanismus und eine Aufhängung mit den Führungsschienen verbunden. An beiden Seiten der Arbeitsbühne ist ein Auflageriegel angeordnet, mit dessen Hilfe die Arbeitsbühne auf den Gerüsttürmen aufgelegt wird. Auf dem Auflageriegel sind Fallklinken angeordnet, die einen Absturz der Arbeitsbühne verhindert, indem sie beim Reißen der Kette des Hubmechanismus in die Aussparungen der Führungsschienen einrasten.DE-OS 31 14 602 describes a device for work scaffolding with a lifting and lowering work platform with associated safety device. The work platform is arranged between four recessed guide rails and connected to the guide rails on both sides by a lifting mechanism and a suspension. A support bar is arranged on both sides of the work platform, with the help of which the work platform is opened is placed on the scaffolding towers. Drop pawls are arranged on the support bar, which prevents the working platform from falling by snapping into the recesses in the guide rails when the chain of the lifting mechanism breaks.
Aus der DE-OS 34 15 074 ist eine Hubarbeitsbühne, insbesondere eine Arbeitsbühne für Bauhandwerker bekannt. Die Hubarbeitsbühne mit einer höhenverstellbar mit einem Gestell verbundenen Arbeitsplattform weist eine Arbeitsplattform mit wenigstens zwei auf Abstand voneinander angeordneten und durch Längsträger miteinander verbindbaren Querträgern auf, die mit Führungsgliedern versehen sind, über die die Querträger jeweils höhenverstellbar an oder in einem Ständer geführt sind.From DE-OS 34 15 074 an aerial work platform, in particular a work platform for construction workers is known. The aerial work platform with a height-adjustable work platform connected to a frame has a work platform with at least two cross beams which are arranged at a distance from one another and can be connected to one another by longitudinal beams and which are provided with guide members via which the cross beams are each adjustable in height on or in a stand.
Der Erfindung liegt die Aufgabe zugrunde, ein Hubgerüst der einleitend genannten Art so auszubilden, daß sich das Gerüst durch gerüsteigene Einrichtungen selbst aufbaut und abbaut, so daß zum Aufbau auch eines relativ großen Gerüstes vergleichsweise wenige Bedienungspersonen erforderlich sind.The invention has for its object to provide a mast of the type mentioned in such a way that the scaffold itself builds up and dismantles by the scaffold's own facilities, so that comparatively few operators are required to build a relatively large scaffold.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein Gerüstmast wenigstens ein Trageprofil aufweist, an dem wenigstens je eine Zahnstange außen und eine Zahnstange innen vorgesehen sind, daß an den Fahrbühnen Zahnräder und Antriebe für die in den äußeren Zahnstangen laufenden Zahnräder und an einem an den Trageprofilen anschließbaren Schlittenmodul mit Zahnrädern und Antrieben für die in den inneren Zahnstangen laufenden Zahnräder vorgesehen sind und daß an den Gerüstmast Stromschienen sowie an den anschließbaren Fahrbühnen und dem Schlittenmodul Stromabnehmer vorgesehen sind.This object is achieved in that a scaffold mast has at least one support profile, on which at least one toothed rack is provided on the outside and one toothed rack is provided on the inside, on the driving platforms, gears and drives for the gears running in the outer toothed racks and on one of the support profiles connectable slide module with gears and drives are provided for the gears running in the inner racks and that current rails are provided on the scaffold mast and pantographs on the connectable driving platforms and the slide module.
Auf diese Weise gelangt man zu einem Hubgerüst, das von wenigen Personen insbesondere mit Hilfe des Schlittens aufgebaut werden kann, indem der Schlitten die einzelnen Gerüstteile, insbesondere die Gerüstmaste schußweise entlang der bereits an der Fassade befestigten Gerüstmaste nach oben transportiert. Insbesondere sind keine gerüstfremden Hilfsmittel, etwa ein Kran oder dgl. zum Aufbau und Abbau des Gerüstes erforderlich.In this way, a lifting scaffold is obtained which can be assembled by a few people, in particular with the aid of the slide, by the slide, in particular, the individual scaffolding parts the scaffolding masts are transported upwards in shots along the scaffolding masts already attached to the facade. In particular, no auxiliary equipment, such as a crane or the like, is required to assemble and disassemble the scaffold.
Statt eines Trageprofils besteht auch die Möglichkeit, daß der Gerüstmast zwei Trageprofile aufweist, die durch Streben und dergleichen miteinander verbunden sind.Instead of a support profile, there is also the possibility that the scaffold mast has two support profiles which are connected to one another by struts and the like.
Es empfiehlt sich, daß der Schlitten so ausgerüstet ist, daß er zusätzliche Funktionen übernehmen kann, wie beispielsweise Kranersatz, Personallift, Materiallift und dergleichen.It is recommended that the carriage be equipped so that it can take on additional functions such as crane replacement, personnel lift, material lift and the like.
Zweckmäßig ist eines der Schlittenmodule ein Gerüstmasttransportmodul. - Somit ist es möglich, mit dem Schlittenmodul entlang bereits teilweise aufgebauter Gerüstmaste weitere Gerüstmastmodule nach oben zum weiteren Aufbau des Gerüstes zu transportieren bzw. umgekehrt Gerüstmastschüsse beim Abbauen des Hubgerüstes von oben nach unten zu transportieren.One of the slide modules is expediently a scaffold mast transport module. - It is thus possible to use the slide module to transport further scaffold mast modules upwards along the already partially erected scaffold masts for further erection of the scaffold or, conversely, to transport scaffold mast shots from top to bottom when dismantling the mast.
Der Schlittenmodul kann zweckmäßig auch als Personal- und/oder Materiallift ausgebildet sein. - Dadurch können bei fertigem Gerüst Personen das Gerüst befahren bzw. besteigen und außerdem ist es möglich die bei den auszuführenden Arbeiten erforderlichen Materialien und Werkzeuge zu transportieren.The slide module can expediently also be designed as a personnel and / or material lift. - This allows people to drive or climb the scaffold when the scaffold is finished and it is also possible to transport the materials and tools required for the work to be carried out.
Zweckmäßig ist der Personal- und/oder Materiallift zu beiden Seiten um den Gerüstmast herum zur Fassade hin verschwenkbar.The personnel and / or material lift is expediently pivotable on both sides around the scaffolding mast towards the facade.
Mitunter ist es zweckmäßig, daß eines der Schlittenmodule ein Kran ist. - Dadurch besteht die Möglichkeit, Materialien vom Hubgerüst aus selbst von Lastkraftwagen und dergleichen abzuladen, ohne daß es eines zusätzlichen Krans bzw. Autokrans bedarf.Sometimes it is useful that one of the sled modules is a crane. - This makes it possible to unload materials from the mast itself from trucks and the like, without the need for an additional crane or truck crane.
In weiterer Ausgestaltung der Erfindung kann das Hubgerüst so ausgebildet sein, daß die Fahrbühnen mit einem Positioniergerät ausrüstbar sind, welches mit einer fahrbaren Lafette über die gesamte Breite der Fahrbühne bewegbar ist. - Mit einem derartigen Positioniergerät besteht die Möglichkeit, die Bewegungen
- a) Heben und Senken,
- b) Seitenverschieben nach rechts und links,
- c) Längsverschieben nach vorn und zurück,
- d) Neigen um eine horizontale Achse oben nach rechts und links,
- e) Drehen um eine vertikale Achse rechtsherum und linksherum und
- f) Schwenken um eine horizontale Querachse
- a) lifting and lowering,
- b) shifting to the right and left,
- c) longitudinal displacement forward and backward,
- d) tilting to the right and left about a horizontal axis,
- e) rotating around a vertical axis clockwise and counter clockwise and
- f) pivoting about a horizontal transverse axis
Vorteilhafterweise ist die Fahrbühne in ihrer Länge zwischen den Gerüstmasten frei festlegbar.The length of the driving platform can advantageously be freely determined between the scaffolding masts.
Es empfiehlt sich, daß die Fahrbühnen auf Schienen horizontal und parallel zur Fassadenwand hin und in entgegengesetzter Richtung verfahrbar sind.It is recommended that the platforms can be moved horizontally and parallel to the facade wall and in the opposite direction.
Des weiteren ist es zweckmäßig, wenn das zur Fassade weisende Fahrbühnengeländer zur Erweiterung des Bühnenbodens zur Fassade hin zu nutzen ist.Furthermore, it is expedient if the driving platform railing facing the facade is to be used to extend the stage floor to the facade.
Zweckmäßig ist an dem Schlitten ein elektrischer oder elektrohydraulischer Antrieb für die auf den inneren Zahnstangen laufenden Zahnräder vorgesehen.An electric or electrohydraulic drive is expediently provided on the slide for the gearwheels running on the inner toothed racks.
In weiterer Ausgestaltung der Erfindung kann das Hubgerüst so ausgebildet sein, daß die Fahrbühnen elektrische oder elekrohydraulische Antriebe zum Antrieb der Zahnräder aufweisen.In a further embodiment of the invention, the mast can be designed so that the driving platforms have electrical or electro-hydraulic drives for driving the gear wheels.
Vorteilhafterweise sind je Antrieb zwei Zahnräder übereinanderliegend vorgesehen.Two gears are advantageously provided one above the other for each drive.
Es besteht auch die Möglichkeit, daß je Antrieb zwei Zahnräder gegenüberliegend vorgesehen sind.There is also the possibility that two gears are provided opposite each drive.
Zweckmäßig sind an den Trageprofilen der Gerüstmaste gegenüberliegend je zwei Zahnstangen vorgesehen, in denen je ein Zahnrad läuft.Two racks, in each of which a gearwheel runs, are expediently provided on the support profiles of the scaffolding masts.
Es ist jedoch auch möglich, daß wenigstens ein Zahnrad zur Sicherung gegen Absturz des Schlittens und der Fahrbühne vorgesehen ist bzw. mit einer Vorrichtung zu diesem Zweck ausgestattet ist.However, it is also possible for at least one gear wheel to be provided to prevent the carriage and the platform from falling, or to be equipped with a device for this purpose.
Zur Vermeidung von Unfällen empfiehlt es sich, daß je eines der übereinander liegenden Zahnräder zur Sicherung gegen Absturz des Schlittens und der Fahrbühne vorgesehen ist.To avoid accidents, it is recommended that one of the superimposed gears is provided to prevent the carriage and the platform from falling.
Nach dem Aufstellen von mindestens zwei parallelen Gerüstmasten kann die erste Fahrbühne zwischen den Gerüstmasten eingefügt werden und zum Aufsetzen des nächsten Gerüstmastschusses bis an das obere Ende der bereits stehenden Gerüstmaste fahren.After setting up at least two parallel scaffolding masts, the first driving platform can be inserted between the scaffolding masts and, to put on the next scaffolding mast shot, move up to the upper end of the scaffolding masts that are already standing.
Ein in der Fahrbühne mitfahrender Monteur ist in der Lage, den nächsten hochgefahrenen Gerüstmastschuß am bereits stehenden Gerüstmast und an der Fassade zu befestigen. Nachdem mindestens zwei Gerüstmastschüsse aufgestockt worden sind, kann der Monteur mit der Fahrbühne bis zum Endpunkt der vorher aufgestockten Gerüstmaste fahren und dort für die weitere Aufstockung das Hochfahren des nächsten Gerüstmastschusses abwarten. Mit einem zusätzlichen Monteur zum Aufnehmen der Mastteile am Boden bzw. auf der Plattform sind somit zwei Monteure ausreichend, um in kurzer Zeit große Fassadenflächen mit Fahrgerüsten zu belegen.A fitter traveling in the driving platform is able to attach the next raised scaffold mast shot to the already standing scaffold mast and to the facade. After at least two scaffolding mast shots have been raised, the fitter can drive the platform to the end point of the previously scaffolded masts and wait for the next scaffolding mast shot to be raised there for further extension. With an additional fitter to pick up the mast parts on the floor or on the Two fitters are therefore sufficient to quickly cover large facade areas with mobile scaffolding.
Durch das Verfahren der Gerüstbrücken auf horizontalen Schienen senkrecht zur Fassadenwand und in entgegengesetzter Richtung ergibt sich der Vorteil, daß zwischen der Fassade und der Fahrbühne keine absturzgefährdenden Zwischenräume belassen sind.By moving the scaffolding bridges on horizontal rails perpendicular to the facade wall and in the opposite direction, there is the advantage that there are no gaps between the facade and the driving platform that could endanger the fall.
Darüber hinaus besteht die Möglichkeit, eventuell vorstehende Bauteile der Fassade zu umfahren.There is also the option of bypassing any projecting components on the facade.
Dies kann auch dadurch erreicht werden, daß durch Einfalten des fassadenseitigen Geländers der Fahrbühne zum Bühnenboden hin ein zusätzliches Stück Bühnenboden geschaffen wird, das den Freiraum zwischen Fassade und Bühne ausfüllt. Dies hat zudem den Vorteil, daß nach Ablassen des Geländers zwischen dem Monteur und der Fassade keine störenden Bauteile der Fahrbühne mehr vorhanden sind.This can also be achieved in that an additional piece of stage floor is created by folding the railing on the facade side of the driving platform towards the stage floor, which fills the space between the facade and the stage. This also has the advantage that after lowering the railing between the fitter and the facade, there are no more disturbing components of the driving platform.
Zwischen den einzelnen Gerüstmasten können beliebig viele Fahrbühnen unabhängig voneinander an den Gerüstmasten entlang verfahren werden. Über die am Gerüstmast befindlichen Stromabnehmer können die Fahrbühnen mit Strom für die Werkzeuge der Monteure ausgestattet werden. Die Fahrbühnenlänge zwischen den Masten ist über einzeln zu verbindende Bühnensegmente frei wählbar.Any number of lifting platforms can be moved independently of one another along the scaffolding masts between the individual scaffolding masts. Via the pantographs on the scaffolding mast, the driving platforms can be equipped with electricity for the tools of the fitters. The length of the platform between the masts can be freely selected using individually connected platform segments.
Zur Montage großer Bauteile können mehrere Bühnen gekuppelt werden. An der Fahrbühne sind über horizontale, parallel zur Fassade verlaufende Führungsschienen auf einer Lafette laufende Positioniergeräte vorgesehen, die im einzelnen die Funktionen
- a) Aufnehmen von Platten oder stabförmigen Bauteilen vom Boden oder vom Materiallift,
- b) Bewegen dieser Platten,
- c) genaues Positionieren dieser Bauteile und
- d) Abgeben dieser Bauteile nach dem Befestigen an der Fassade
- a) Picking up plates or rod-shaped components from the floor or from the material lift,
- b) moving these plates,
- c) exact positioning of these components and
- d) Deliver these components after fastening them to the facade
Nachdem alle Gerüstmaste aufgestellt sind, kann der Schlitten durch mehrere auswechselbare Module mit zusätzlichen Funktionen ausgestattet werden, zum Beispiel einem Kranausleger, der bei einem oben über das Dach hinausgehenden Gerüstmast große und schwere Bauteile ähnlich einem sonst üblichen Baukran auf das Dach befördern kann, oder einem Personen- und/oder Materiallift, der nicht nur Monteure und Material zwischen den einzelnen Fahrbühnen auf das Dach sondern durch Einschwenken bis an die Fassade oder an Bauwerksöffnungen in das Gebäude hinein befördern kann.After all scaffolding masts have been set up, the slide can be equipped with additional functions by means of several interchangeable modules, for example a crane boom, which can transport large and heavy components to the roof similar to an otherwise usual construction crane when a scaffolding mast extends above the roof, or one Passenger and / or material lift, which can not only move fitters and material between the individual driving platforms onto the roof, but can also be swung into the building or into the building through the openings in the building.
An einem Gerüstmast können in zweckmäßiger Anordnung zum Beispiel ein Schlitten mit Kranmodul und ein bis beliebige viele Schlitten mit Liftmodulen angeschlossen sein, die unabhängig voneinander verfahren werden können.In a practical arrangement, a scaffold mast can be connected, for example, to a slide with a crane module and to any number of slides with lift modules, which can be moved independently of one another.
Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispieles des näheren erläutert.The invention is explained below with reference to an embodiment shown in the drawing.
