Description

Die Erfindung betrifft ein Adapterelement für den durchgängigen, stirnseitigen Anschluß von Gerüstgruppen mit unterschiedlich breiten Rahmenelementen, die aus zwei im Bereich ihrer Enden durch mindestens je eine obere und untere Quertraverse miteinander verbundenen Ständern bestehen.The invention relates to an adapter element for the end-to-end connection of scaffolding groups with frame elements of different widths, consisting of two in Area of their ends by at least one upper and lower crossbeam interconnected stands consist.

Gerüstgruppen der vorstehend genannten Art dienen zum Einrüsten von Gebäuden, um Arbeiten beispielsweise an der Außenseite der Wände eines Hauses durchführen zu können. Bekannt sind hier schmale und breite Gerüstgruppen, die unterschiedliche Nutzlasten haben. In der Regel ist es so daß breitere Gerüstgruppen auch die höhere Nutzlast besitzen. Diese breiteren Gerüstgruppen besitzen auch entsprechend breitere Rahmenelemente, wobei es vorkommen kann, daß für ein und dasselbe Haus unterschiedliche Nutzlasten erforderlich sind. Dies hat häufig zur Folge, daß das gesamte Haus mit einer breiteren Gerüstgruppe insgesamt eingerüstet wird, obwohl für bestimmte Bereiche des Hauses schmalere Gerüstgruppen ausreichend wären. Werden verschieden breite bekannte Gerüstgruppen aufgebaut, so ergaben sich stets Probleme bei der Verbindung von breiteren und schmaleren Gerüstgruppen, d. h. diese konnten nicht durchgängig mit geringem Abstand miteinander verbunden werden.Scaffolding groups of the type mentioned above are used for Scaffolding buildings to work on, for example To be able to perform outside of the walls of a house. Narrow and broad scaffold groups are known here have different payloads. As a rule, it is that wider scaffolding groups also have the higher payload have. These broad scaffold groups also have correspondingly wider frame elements, where it occurs can that be different for one and the same house Payloads are required. This often means that the entire house with a wider scaffolding group overall is scaffolded, although for certain areas of narrow house scaffolding groups would be sufficient. If different widths of known scaffold groups are set up, so there were always problems connecting wider and narrower scaffold groups, d. H. these could not consistently with a small distance between them get connected.

Der Erfindung liegt die Aufgabe zugrunde, einen Adapter vorzuschlagen, der es in einfacher Weise ermöglicht, schmalere und breitere Gerüstgruppen durchgängig, ohne erhöhten Aufwand, stirnseitig miteinander zu verbinden.The invention has for its object an adapter to propose that makes it easy to narrower and wider scaffold groups throughout, without increased effort to connect to each other at the end.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Adapterelement stielförmig mit einer Länge ausgebildet ist, die in etwa dem Abstand der Quertraversen der Rahmenelemente entspricht, wobei an den Enden des Stieles Befestigungsmittel für den lösbaren Anschluß an die Quertraversen vorgesehen sind und wobei vom Stiel des Adapterelementes mindestens ein Arm senkrecht abstrebt, dessen Ende mit Befestigungsmitteln für den lösbaren Anschluß an einen Ständer des Rahmenelementes versehen ist.This object is achieved in that the Adapter element is shaped like a stem with a length, which is roughly the distance between the crossbeams of the Corresponds to frame elements, being at the ends of the stem Fasteners for the detachable connection to the Cross members are provided and being from the stalk of the Adapter element strives at least one arm vertically, the end with fasteners for the detachable Connection to a stand of the frame element is provided.

Ein derartiges Adapterelement wird in den jeweils breiteren Gerüstrahmen eingesetzt, wobei die Befestigungselemente des Stieles vorteilhaft gabelförmig ausgebildet sind, so daß diese auf die untere Quertraverse aufgesetzt werden können und die obere Quertraverse umgreift. Senkrecht zum Stiel des Adapterelementes sind die Arme angebracht, die an ihren Enden gleichfalls Befestigungsmittel aufweisen, die die senkrecht angeordneten Ständer der Rahmenelemente umgreifen. Bereits hierdurch ist ein fester Verbund des Adapterelementes mit dem Rahmenelement gegeben. Vorteilhaft wird jedoch zumindest das obere Befestigungselement des Stieles mittels einer Klemmvorrichtung mit der oberen oder den oberen Quertraversen verspannt, so daß hierdurch jegliche Verschiebung längs der Quertraversen ausgeschlossen ist. Such an adapter element is in the wider Scaffolding used, the fasteners of the Stalks are advantageously fork-shaped, so that these can be placed on the lower crossbar and embraces the upper crossbar. Perpendicular to the stem the adapter element, the arms are attached to their Ends also have fasteners that vertically arranged stands of the frame elements reach around. This is already a firm bond of the Given adapter element with the frame element. Advantageous however, at least the upper fastener of the By means of a clamping device with the upper or the upper crossbar braced, so that any Displacement along the crossbeams excluded is.

Die Arme, die mit den Ständern der Rahmenelemente verbunden sind, dienen gleichzeitig als stirnseitiger Abschluß des breiteren Rahmenelementes, wobei hier vorteilhaft zwei Arme vorgesehen sind, die im unteren und mittleren Bereich des Stieles des Adapterelementes angebracht sind.The arms connected to the stands of the frame elements are, at the same time, serve as the end of the wider frame element, here advantageously two arms are provided in the lower and middle area of the Handle of the adapter element are attached.

An der den Armen gegenüberliegenden Seite der Adapterelemente sind die gleichen Befestigungsmittel angeordnet, wie sie auch die Ständer des Rahmenelementes aufweisen. Diese Befestigungsmittel bilden Adapter zur Befestigung von Seitenbrettern, Geländerstangen, etc.On the side of the adapter elements opposite the arms the same fasteners are arranged, as they also have the stands of the frame element. These fasteners form adapters for fastening Side boards, balusters, etc.

In Fig. 1 ist eine breite Gerüstgruppe I mit einer schmaleren Gerüstgruppe II durchgängig zusammengebaut. Die Gerüstgruppe I besteht aus vier Rahmenelementen 2, die in bekannter Weise aufeinandergesetzt sind. Diese Rahmenelemente 2 werden über Belagbühnen 15 miteinander verbunden. An den Seiten sind Geländer 16 angebracht, die in erster Linie zur Sicherung der arbeitenden Personen dienen. An diese breite Gerüstgruppe I ist eine schmale Gerüstgruppe II angebaut, die entsprechend schmalere Rahmenelemente 21 aufweist. Zur durchgängigen stirnseitigen Verbindung der beiden Gerüstgruppen I und II dient ein Adapterelement 1, das in das Rahmenelement 2 der breiten Gerüstgruppe I eingesetzt ist und über Arme 9 zum einen an den Ständern 5 des Rahmenelementes 2 und über Befestigungsmittel 7, 8 an den Quertraversen 3 und 4 des Rahmenelementes 2 angeschlossen ist. Die Arme 9 dienen gleichfalls als stirnseitiger Abschluß, so daß auf das Anbringen weiterer Geländerelemente verzichtet werden kann.In Fig. 1 is a broad framework group I with a Narrow scaffolding group II consistently assembled. The Scaffolding group I consists of four frame elements 2, which in are known on top of each other. This Frame elements 2 are connected to one another via covering platforms 15 connected. Railings 16 are attached to the sides primarily to secure the working people to serve. There is a narrow one at this broad scaffolding group I. Scaffold group II attached, the correspondingly narrower Has frame elements 21. For continuous frontal Connection of the two scaffold groups I and II is used Adapter element 1, which in the frame element 2 of the wide Scaffolding group I is used and arms 9 on the one hand the stands 5 of the frame element 2 and over Fasteners 7, 8 on the cross members 3 and 4 of the Frame element 2 is connected. The arms 9 serve also as a front end, so that on the Attaching other railing elements can be dispensed with.

In der Fig. 2 ist das Rahmenelement 2 der Gerüstgruppe I in Seitenansicht dargestellt. Dieses Rahmenelement besteht in bekannter Art und Weise aus einer unteren Quertraverse 3 und einer oberen Quertraverse 4, die zwei seitliche Ständer 5, 6 miteinander verbinden. Im Ausführungsbeispiel der Fig. 2 ist die obere Quertraverse 4 durch ein weiteres Traversenstück 41 versteift, wodurch eine erhöhte Tragfähigkeit und eine erhöhte Steifigkeit des Rahmenelementes 2 erhalten wird. Zur Verkleinerung des Durchganges und zum Anschluß der schmalen Gerüstgruppe II ist das Adapterelement 1 zwischen die Ständer 3 und 4 eingesetzt, wobei, wie dies am besten aus den Fig. 4 und 5 zu ersehen ist, das obere Befestigungselement 8 wie auch das untere Befestigungselement 7 gabelförmig ausgebildet sind und die Traversen 3 bzw. 4 seitlich umgreifen. Dieses Adapterelement 1 kann nachträglich einfach in das Rahmenelement 2 eingesetzt werden. Hierzu braucht lediglich das Adapterelement 1 auf die untere Quertraverse 3 schräg aufgesetzt werden, um dann in die senkrechte Lage eingedreht zu werden. Bereits hierdurch ist die seitliche Befestigung des Adapterelementes 1 gegeben. Um zu verhindern, daß das Adapterelement 1 aus der senkrechten Lage herausgedreht werden kann, sind Arme 9 an diesem befestigt, die mittels Befestigungselemente 10 an den Ständern 5 bzw. 6 befestigt sind. Diese Befestigungselemente 10 umgreifen vorteilhaft den Ständer 5 vollständig und sind mit entsprechenden Schraubbolzen bekannter Art und Weise gesichert. Hierdurch ist ein praktisch starrer Einbau des Adapterelementes 1 in den Gerüstrahmen 2 gegeben.2, the frame element 2 of the scaffolding group I is in Side view shown. This frame element consists of known manner from a lower cross member 3rd and an upper crossbar 4, the two side stands 5, 6 connect with each other. In the embodiment of FIG. 2 is the upper crossbar 4 by another Truss piece 41 stiffened, thereby increasing Load capacity and increased rigidity of the Frame element 2 is obtained. To reduce the Passage and for connecting the narrow scaffolding group II is the adapter element 1 between the stands 3 and 4 used, as best shown in FIGS. 4 and 5 can be seen, the upper fastener 8 as well the lower fastening element 7 is fork-shaped are and the crossbars 3 and 4 encompass laterally. This Adapter element 1 can easily be retrofitted into that Frame element 2 are used. All you need is this the adapter element 1 on the lower crossbar 3 obliquely be put on, then screwed into the vertical position to become. This is already the side Attachment of the adapter element 1 given. To prevent, that the adapter element 1 from the vertical position can be unscrewed, arms 9 are attached to this, which by means of fastening elements 10 on the stands 5 or 6 are attached. Grip around these fasteners 10 advantageous the stand 5 completely and are with corresponding screw bolt known manner secured. This is a practically rigid installation of the Given adapter element 1 in the framework 2.

Am Adapterelement 1 sind vorteilhaft zwei Arme 9 angebracht, die im unteren und im mittleren Bereich angeordnet sind und somit gleichzeitig einen stirnseitigen Abschluß des Rahmenelementes 2 bilden. An dem Stiel des Adapterelementes 1 sind Adapterstücke 11 angeordnet, die auf der den Armen 9 abgesetzten Seite des Stieles des Adapterelementes 1 liegen. Diese Adapterstücke 11 haben den gleichen Abstand zu der unteren wie auch oberen Quertraverse 3, 4, wie die Adapterelemente 11 der Ständer 5 der kleineren Rahmenelemente II. Der Abstand dieser Adapterelemente 11 sollte im übrigen auch den Abständen der Adapterelemente der Rahmen 2 entsprechen, um eine einfache Anbringung von Seitenborden, Geländern 16, etc. zu ermöglichen.Two arms 9 are advantageously attached to the adapter element 1, which are arranged in the lower and middle area are and thus at the same time an end closure form the frame element 2. On the stem of the Adapter element 1, adapter pieces 11 are arranged, the on the arm 9 side of the stem of the Adapter element 1 lie. These adapter pieces 11 have the equal distance to the bottom as well as the top Crossbar 3, 4, like the adapter elements 11 of the stand 5th the smaller frame elements II. The distance between them Adapter elements 11 should also the distances of the Adapter elements of the frame 2 correspond to a simple one Attachment of side rims, railings 16, etc. to enable.

Das Ausführungsbeispiel nach Fig. 7 unterscheidet sich von dem Ausführungsbeispiel nach Fig. 2 im wesentlichen dadurch, daß die obere Quertraverse 4 einstückig ausgebildet ist, so daß das obere Befestigungsmittel 8 entsprechend kürzer und die Länge des Stieles des Adapterelementes entsprechend länger ausgebildet ist. 7 differs from the embodiment of FIG. 2 essentially in that the upper crossbar 4 is formed in one piece is, so that the upper fastening means 8 accordingly shorter and the length of the stem of the adapter element is formed accordingly longer.
