- DE 30 14 212 A1 discloses a scaffolding designed as a mobile scaffold consisting of two lateral conductors, one or more covering panels arranged one above the other, and components that are adjustable in length or height.
- the invention is therefore based on the object of creating a work scaffold with a variable standing width for simple and reliable adaptability to the respective working conditions.
- the invention is characterized by the technical teaching of claim 1.
- An essential feature of the invention is that with the aid of a coupling fitting at the free end of a cross member, an extension arm with an adjustable foot is pivotally attached.
- a work scaffold with a relatively small stand width is therefore proposed, with simple and reliable adaptability to the respective working conditions being ensured.
- the stand width must also be increased accordingly.

- the adjusting foot In the first-mentioned solution, where the extension arm is formed with a lower eyelet which encompasses the tubular part of the traverse, the adjusting foot must first be removed from this tubular part when the extension arm is being installed, so that it can then be mounted at the end of the extension arm.
- the crosshead must be supported during this time.
- the second solution provides that the extension arm can be attached to this tube part when the adjustment foot is located in the tube part.

Abstract
Description
Die Erfindung betrifft ein Arbeitsgerüst nach dem Oberbegriff des Patentanspruchs 1.
Hierbei besteht das Arbeitsgerüst aus horizontalen, einen gegenseitigen Abstand voneinander einnehmenden, Traversen, die durch eine Einstiegsbühne miteinander verbunden sind. Am Ende jeder Traverse ist in ansich bekannter Weise ein Verstellfuss angeordnet. Auf den Traversen sind vertikale Gerüstrahmen angeordnet, die durch Diagonalstreben verbunden sind, wobei die Gerüstrahmen mit horizontalen Arbeitsbühnen verbunden sind, welche Arbeitsbühnen parallel zu der untersten, auf der Traverse liegenden, Einstiegsbühne angeordnet sind. Bei derartigen Arbeitsgerüsten besteht das Problem, daß bei höheren Aufbauten es erforderlich ist, die Standbreite zu vergrößern.The invention relates to a scaffolding according to the preamble of claim 1.
Here, the work scaffolding consists of horizontal, mutually spaced trusses, which are connected to each other by an entry platform. At the end of each traverse an adjustable foot is arranged in a manner known per se. Vertical scaffold frames are arranged on the trusses, which are connected by diagonal struts, the scaffold frames being connected to horizontal work platforms, which work platforms are arranged parallel to the lowest entry platform lying on the crossmember. With such work scaffolds there is the problem that with higher structures it is necessary to increase the standing width.
Nach dem Dokument ,,plettac Sicherheits-Fahrgerüste aus Aluminium", Prospekt der Firma plettac GmbH, Plettenberg, September 1991, ist ein Arbeitsgerüst, bestehend aus horizontalen, einen gegenseitigen Abstand voneinander einnehmenden, Traversen, deren Länge veränderbar ist und die durch eine Einstiegsbühne miteinander verbunden sind (,,Baukastensystem"), wobei auf den Traversen vertikale Gerüstteile befestigt sind und an jedem Ende der Traversen ein Verstellfuß lösbar angeordnet ist, und mindestens an einem freien Ende jeder Traverse mittels eines Kupplungsbeschlages ein Verlängerungsarm mit einem Verstellfuß angebracht ist, bekannt.According to the document "plettac safety mobile scaffolding made of aluminum", brochure of the company plettac GmbH, Plettenberg, September 1991, is a working scaffold consisting of horizontal, mutually spacing, trusses, the length of which can be changed and which are joined together by an entry platform are connected ("modular system"), vertical scaffold parts are attached to the cross members and an adjustable foot is detachably arranged at each end of the cross members, and an extension arm with an adjustable foot is attached to at least one free end of each cross member by means of a coupling fitting.
Weiterhin ist durch die DE 30 14 212 Al ein als Fahrgerüst ausgebildetes Baugerüst aus zwei seitlichen Leitern, einer oder mehreren im Abstand übereinander angeordneten Belagtafeln, längs- oder höhenverstellbaren Bauteilen, vorbekannt.Furthermore, DE 30 14 212 A1 discloses a scaffolding designed as a mobile scaffold consisting of two lateral conductors, one or more covering panels arranged one above the other, and components that are adjustable in length or height.
Nachteilig bei diesen vorgenannten technischen Lösungen ist die mangelnde Anpassbarkeit an sich rasch ändernder Arbeitsbedingungen.A disadvantage of these technical solutions is the lack of adaptability to rapidly changing working conditions.
Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Arbeitsgerüst mit veränderbarer Standbreite zur einfachen und betriebssicheren Anpassbarkeit an die jeweiligen Arbeitsbedingungen zu schaffen.The invention is therefore based on the object of creating a work scaffold with a variable standing width for simple and reliable adaptability to the respective working conditions.
Zur Lösung der gestellten Aufgabe ist die Erfindung durch die technische Lehre des Anspruchs 1 gekennzeichnet.To achieve the object, the invention is characterized by the technical teaching of claim 1.
Wesentliches Merkmal der Erfindung ist, daß mit Hilfe eines Kupplungsbeschlages am freien Ende jeweils einer Traverse ein Verlängerungsarm mit einem Verstellfuß schwenkbar angebracht ist.An essential feature of the invention is that with the aid of a coupling fitting at the free end of a cross member, an extension arm with an adjustable foot is pivotally attached.
Es wird also ein Arbeitsgerüst mit einer relativ kleinen Standbreite vorgeschlagen, wobei eine einfache und betriebssichere Anpassbarkeit an die jeweiligen Arbeitsbedingungen gewährleistet ist.A work scaffold with a relatively small stand width is therefore proposed, with simple and reliable adaptability to the respective working conditions being ensured.
Soll dieses Arbeitsgerüst nun an einer anderen Baustelle eingesetzt werden, wo eine größere Arbeitshöhe erforderlich ist, muß entsprechend auch die Standbreite vergrößert werden. Zu diesem Zweck wird einfach am einen Ende der jeweiligen Traverse der Verstellfuß entnommen, und es wird an dieser Stelle ein Kupplungsbeschlag angesetzt der mit einem zusätzlichen Verlängerungsarm verbunden wird.If this scaffolding is to be used at another construction site where a larger working height is required, the stand width must also be increased accordingly. For this purpose, the adjustable foot is simply removed from one end of the respective traverse, and a coupling fitting is attached at this point, which is connected to an additional extension arm.
Der Verlängerungsarm entspricht der Verlängerung der Traverse und trägt an seinem freien, äusseren Ende wiederum eine Aufnahme (Rundteil) für die Halterung des Verstellfußes.The extension arm corresponds to the extension of the traverse and has a receptacle (round part) for holding the adjustable foot at its free, outer end.
Auf diese Weise ist gewährleistet, daß mit einfachen Mitteln nachträglich das Arbeitsgerüst von einer relativ kleinen Standbreite auf eine größere Standbreite vergrössert werden kann.In this way it is ensured that the work scaffold can be subsequently enlarged from a relatively small standing width to a larger standing width using simple means.
Damit besteht der Vorteil, daß das Arbeitsgerüst bei kleiner Standbreite einem Standardmaß entspricht und dadurch - wegen des Wegfalls des Erfordernisses der Vergrößerung der Standbreite - kostengünstig herstellbar ist.This has the advantage that the work scaffold corresponds to a standard size with a small stand width and can therefore be produced inexpensively because the need to increase the stand width is eliminated.
Für einige Anwendungsfälle, wenn eine Vergrößerung der Standbreite erwünscht wird, wird dann einfach ein Verlängerungsarm hinzugenommen, der mit einem dazugehörenden Kupplungsbeschlag mit der Traverse gekuppelt wird und der wiederum an seinem äusseren Ende die Aufnahme für den Verstellfuß aufweist.For some applications, if an increase in the standing width is desired, an extension arm is simply added, which is coupled to the crossbar with an associated coupling fitting and which in turn has the receptacle for the adjustable foot at its outer end.
Zur Vergrößerung der Standbreite eines Arbeitsgerüstes sind daher nur mindestens zwei Verlängerungsarme erforderlich.To increase the standing width of a work scaffold, only at least two extension arms are required.
Zur Kupplung des jeweiligen Verlängerungsarmes mit der zugeordneten Traverse gibt es mehrere Möglichkeiten:There are several options for coupling the respective extension arm with the assigned crossbar:
Zunächst wird es bevorzugt, wenn als Kupplungsbeschlag ein Klemmbeschlag verwendet wird, der im wesentlichen wie eine Gerüstkupplung aufgebaut ist, um den Verlängerungsarm an dem Rohrteil der Traverse zu befestigen, um so eine erste von zwei vorhandenen Befestigungen zu schaffen.First of all, it is preferred if a clamping fitting is used as the coupling fitting, which is constructed essentially like a scaffolding coupling, in order to fasten the extension arm to the tubular part of the crossmember, in order to create a first of two existing fastenings.
Die zweite Befestigung des Verlängerungsarmes besteht darin, daß entweder das Rohrteil der Traverse mit einer Öse des Verlängerungsarms umgriffen wird und hierdurch eine formstabile Halterung geschaffen wird.The second attachment of the extension arm is that either the tubular part of the traverse is gripped with an eyelet of the extension arm and thereby a dimensionally stable bracket is created.
In einer zweiten Ausführungsform wird statt der Verwendung einer Öse ein abgekantetes Hakenteil vorgeschlagen, welches die Traverse von unten umgreift.In a second embodiment, instead of using an eyelet, a beveled hook part is proposed, which engages around the crossbeam from below.
Bei beiden Ausführungsformen wird es bevorzugt, wenn in der Arbeitsstellung der Verlängerungsarm die Fortsetzung der Längsachse der Traverse bildet, um so zu vermeiden, daß sich der Verlängerungsarm in der Arbeitsstellung unbeabsichtigt zu der Traverse erstreckt.In both embodiments, it is preferred if in the working position the extension arm forms the continuation of the longitudinal axis of the cross member, in order to avoid that the extension arm inadvertently extends to the cross member in the working position.
Es ist aber vorgesehen, bei Lockerung des Klemmbeschlages den Verlängerungsarm einwärts und auswärts schwenkbar zu gestalten, um beispielsweise das Arbeitsgerüst durch enge Durchfahrten hindurchfahren zu können und dergleichen mehr.However, it is provided that when the clamp fitting is loosened, the extension arm can be pivoted inwards and outwards, for example in order to be able to drive through the work scaffold through narrow passages and the like.
Bei der erstgenannten Lösung, wo der Verlängerungsarm mit einer unteren Öse ausgebildet ist, welche das Rohrteil der Traverse umgreift, muß bei der Montage des Verlängerungsarmes aus diesem Rohrteil zunächst der Verstellfuß herausgenommen werden, um diesen dann am Ende des Verlängerungsarmes montieren zu können. In dieser Zeit muß die Traverse abgestützt werden.In the first-mentioned solution, where the extension arm is formed with a lower eyelet which encompasses the tubular part of the traverse, the adjusting foot must first be removed from this tubular part when the extension arm is being installed, so that it can then be mounted at the end of the extension arm. The crosshead must be supported during this time.
Um dies zu vermeiden, ist die zweite Lösung vorgesehen, die vorsieht, daß bei in dem Rohrteil befindlichem Verstellfuß der Verlängerungsarm an diesem Rohrteil befestigt werden kann. Der Verstellfuß kann dann an dieser Stelle verbleiben und der Verlängerungsarm trägt dann an seinem äußeren Ende einen weiteren Verstellfuß, so daß eine zusätzliche Abstützung über zwei im Abstand voneinander angeordnete Verstellfüsse gegeben ist.In order to avoid this, the second solution is provided, which provides that the extension arm can be attached to this tube part when the adjustment foot is located in the tube part. The adjustable foot can then remain at this point and the extension arm then carries a further adjustable foot at its outer end, so that additional support is provided via two adjustable feet arranged at a distance from one another.
Im folgenden wird die Erfindung anhand von mehrere Ausführungswege darstellende Zeichnungen näher erläutert. Hierbei gehen aus den Zeichnungen und ihrer Beschreibung weitere erfindungswesentliche Merkmale und Vorteile der Erfindung hervor.In the following, the invention is explained in more detail with reference to drawings showing several possible embodiments.

Bei dem Arbeitsgerüst 1 nach den Figuren 1 und 2 soll die Standbreite 10 auf die Standbreite 11 vergrößert werden. Das Arbeitsgerüst besteht in ansich bekannter Weise aus horizontalen Traversen 3, die einen gegenseitigen Abstand voneinander einnehmen und die (zeichnerisch nicht dargestellt) durch entsprechende Horizontalbühnen miteinander verbunden sind.In the working scaffold 1 according to FIGS. 1 and 2, the standing
Auf jeder Traverse 3 ist jeweils mindestens ein Gerüstrahmen 2 mit Hilfe von zugeordneten Klemmbeschlägen 4 befestigt. An den Aussenseiten jeder Traverse 3 ist jeweils ein Verstellfuß 5 angeordnet, der in einem mit der Traverse 3 verbundenen Rohrteil 6 verstellbar gehalten ist.At least one

Gemäss Figur 5 besteht die Gerüstkluppe 22 im wesentlichen aus einem Schließteil 15, welches über einen Drehbolzen 17 schwenkbar an einem ortsfesten Halter 21 befestigt ist. Am gegenüberliegenden Ende des Schließteiles 15 ist ein Schlitz angeordnet, durch welchen eine Hammerkopfschraube 18 greift, auf welche eine Ringmutter 14 aufgeschraubt ist.

In the upper area, the coupling fitting 23 in turn has the previously described
Hierbei ist in Verlängerung des Verlängerungsarmes 8 ein Verbindungsteil 20 vorgesehen, an dessen freiem Ende ein Hakenteil 19 angeformt ist. Dieses Hakenteil 19 weist einen abgekröpften Haken auf, der mindestens teilweise gemäss Figur 13 das Rechteckprofil der Traverse 3 umgreift. Das Hakenteil bildet also eine nach oben geöffnete Aufnahme 24, welche sich an der Unterseite der Traverse 3 formschlüssig anlegt, und der nach oben abgekröpfte Haken des Hakenteiles sich an den Seitenflächen der Traverse 3 anlegt.Here, in the extension of the
Damit ist eine absolute Verdrehsicherheit gegeben, d.h. der Verlängerungsarm 8 ist stets in montiertem Zustand in Verlängerung der Längsachse der Traverse 3 montiert.
