Description

Die Erfindung betrifft einen Klemmbeschlag für Arbeitsgerüste nach dem Oberbegriff des Schutzanspruchs 1. Derartige Arbeitsgerüste gibt es als Fahr- oder als Standgerüst und bestehen im wesentlichen aus einer unteren Einstiegsebene, die als Einstiegsbühne bezeichnet wird, welche horizontal angeordnet ist und von der ausgehend vertikale Gerüstrahmen sich nach oben erstrecken, die ggf. durch Diagonalstreben miteinander verbunden sind, wobei an den Oberseiten der Gerüstrahmen weitere Arbeitsbühnen befestigt sind.The invention relates to a clamp fitting for scaffolding according to the preamble of protection claim 1. Such scaffolding is available as a mobile or as a standing scaffold and consists essentially of a lower boarding level, which is referred to as an access platform, which is arranged horizontally and from which vertical scaffolding frames extend upwards, which may be connected by diagonal struts, with further work platforms attached to the top of the scaffolding frame.

Bei der Herstellung derartiger Arbeitsgerüste besteht der Nachteil, daß die einzelnen Bühnen, entweder die untere Einstiegsbühne oder die darüberliegenden Arbeitsbühnen, relativ schwierig mit den dazugehörenden Traversen zu verbinden sind. Problematisch ist nämlich die Verbindung mit den horizontalen Traversen deshalb, weil die dazugehörenden Beschläge in der Regel ein Spiel aufweisen, was dazu führt, daß die einzelnen, horizontal angeordneten und im vertikalen Abstand parallel übereinander angeordneten Bühnen zum Spiel neigen und hierdurch das Arbeitsgerüst instabil wird.In the manufacture of such work scaffolds, there is the disadvantage that the individual platforms, either the lower entry platform or the work platforms above, are relatively difficult to connect to the associated trusses. The connection with the horizontal crossbeams is problematic because the associated fittings generally have a play, which leads to the fact that the individual, horizontally arranged and vertically spaced stages tended to play and the work scaffold thereby becomes unstable.

Bisher ist es nämlich lediglich bekannt, die einzelnen Bühnen an der Stirnseite mit klauenartigen Beschlägen zu versehen, wobei die Klauen dieser Beschläge nach unten geöffnet sind, so daß die Möglichkeit bestand, diese Klauen über die horizontalen Grundtraversen einzuhängen und derart diese einzelnen Bühnen zu befestigen.So far, it is only known to provide the individual stages on the front side with claw-like fittings, the claws of these fittings being open at the bottom, so that there was the possibility of hanging these claws over the horizontal basic cross members and thus fastening these individual platforms.

Damit bestand aber der Nachteil, daß die Klauen keine Verdrehsicherung boten und seitliches Spiel zuließen. Die einzelnen Bühnen waren also nicht spielfrei an den horizontalen Traversen des Arbeitsgerüstes befestigt.However, this had the disadvantage that the claws did not offer any security against rotation and allowed lateral play. The individual stages were therefore not attached to the horizontal trusses of the work scaffold without play.

Der Erfindung liegt die Aufgabe zugrunde, die Befestigung der horizontalen Bühnen an den horizontalen Traversen des Arbeitsgerüstes durch Klemmbeschläge so zu verbessern, daß eine praktisch spielfreie Verbindung besteht.The invention has for its object to improve the attachment of the horizontal stages to the horizontal crossbeams of the scaffolding by means of clamp fittings so that there is a virtually play-free connection.

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 vorliegenden Erfindung ist der Klemmbeschlag, der eine praktisch form- und kraftschlüssige Verbindung zwischen der jeweiligen Bühne und der zugeordneten Traverse bietet.An essential feature of the present invention is the clamp fitting, which offers a practically positive and non-positive connection between the respective platform and the associated cross member.

Wichtig hierbei ist, daß die Traverse mehrkantig ausgebildet ist, z.B. als Vierkant, Rechteckprofil, Dachkantprofil, Ovalprofil oder dergleichen und dafür gesorgt ist, daß der Klemmbeschlag in seinem Innenumfang dem Aussenprofil der Traverse angepasst ist, so daß der Klemmbeschlag diese Traverse formschlüssig umgreift und mit dieser verklemmbar ist.It is important that the crossbeam is polygonal, e.g. as a square, rectangular, roof profile, oval profile or the like and it is ensured that the clamping fitting is adapted in its inner circumference to the outer profile of the cross member, so that the clamping fitting encompasses this cross member in a form-fitting manner and can be clamped to it.

Es wird also ausdrücklich bei der Erfindung ein Rundprofil als Traverse vermieden, weil sich herausgestellt hat, daß aufgrund des allein bestehenden Reibungsschlusses die entstehenden Schließkräfte nicht ausreichen, die jeweilige Bühne spielfrei mit der zugeordneten Traverse zu verbinden. Hier setzt die Neuerung ein, die neben einem Kraftschluß noch einen Formschluß für den Klemmbeschlag vorsieht.It is therefore expressly avoided in the invention a round profile as a traverse, because it has been found that due to the frictional engagement alone, the resulting closing forces are not sufficient to connect the respective stage with the associated traverse without play. This is where the innovation comes in, which, in addition to a frictional connection, also provides a positive connection for the clamp fitting.

Voraussetzung ist also immer, daß man den Klemmbeschlag so in seinem Innenprofil gestaltet, daß er formschlüssig das Profil der von ihm zu umschließenden Traverse umschließt und daß ferner mindestens ein Schließteil vorhanden ist, welches mit einer entsprechenden Schraube so an einer Seite der Traverse schwenkbar anlegbar ist, daß es neben dem erwähnten Formschluß noch zu einem Kraftschluß, d.h. zu einer Verspannung des Klemmbeschlages an der Traverse, kommt.The prerequisite is always that the clamp fitting is designed in its inner profile in such a way that it positively encloses the profile of the crossmember to be enclosed and that at least one locking part is also present, which can be pivoted with a corresponding screw on one side of the crossmember that, in addition to the positive engagement mentioned, there is still a frictional engagement, ie the clamp fitting on the crossbar tensions.

In einer Weiterbildung ist es wesentlich, daß der Klemmbeschlag leicht zu öffnen und zu schließen ist, was mit dem Vorteil verbunden ist, daß beim Öffnen des Klemmbeschlages die gesamte Einstiegsbühne in Bezug zu der feststehenden Traverse verschoben werden kann und im übrigen auch die mit der Traverse verbundenen Gerüstrahmen.In a further development, it is essential that the clamp fitting is easy to open and close, which has the advantage that when the clamp fitting is opened, the entire access platform can be moved in relation to the fixed crossmember and, moreover, that with the crossmember connected scaffolding frames.

Erfindungsgemäss wird der Klemmbeschlag nämlich nicht nur zur Befestigung der jeweiligen Bühnen (Einstiegsbühne und Arbeitsbühnen) verwendet, sondern darüber hinaus auch noch an den Unterseiten der jeweiligen Gerüstrahmen, die mit den gleichartigen Klemmbeschlägen ausgerüstet sind. Beim Öffnen der jeweiligen Klemmbeschläge können somit die Gerüstrahmen und die Bühnen in horizontaler Ebene entlang den Traversen verschoben werden.According to the invention, the clamp fitting is not only used for fastening the respective platforms (entry platform and work platforms), but also on the undersides of the respective scaffolding frames, which are equipped with the same clamp fittings. When the respective clamp fittings are opened, the scaffold frames and the platforms can be moved horizontally along the crossbars.

Dies ist bei Arbeiten an Wänden erforderlich, wo es notwendig sein kann, die Einstiegsbühne und die darüberliegenden Arbeitsbühnen wandnah an den Traversen zu befestigen, um dann bei Veränderung des Arbeitsfortschrittes den gesamten Aufbau entlang der feststehenden Traverse von der Wand wegzuschieben.This is necessary when working on walls, where it may be necessary to attach the entry platform and the work platforms above it to the crossbars, in order to then push the entire structure away from the wall along the fixed crossbar when the work progress changes.

Wichtig ist die stufenlose Verstellung mit Hilfe des erwähnten Klemmbeschlages, d.h. der gesamte Aufbau des Arbeitsgerüstes kann auf den bodenseitig angeordneten Traversen stufenlos verschoben werden, was neu ist.What is important is the continuous adjustment with the help of the mentioned clamp fitting, i.e. the entire structure of the scaffolding can be moved continuously on the trusses on the floor, which is new.

Diese Verschiebung kann dem Arbeitsfortschritt entsprechend angepasst werden, ohne daß die Notwendigkeit besteht, das gesamte Gerüst teilweise abzubauen, um - wie beim Stand der Technik - eine in Stufen gehende Verschiebung (Umstecken) zu erreichen.This shift can be adapted to the progress of work without the need to partially dismantle the entire scaffolding in order to achieve a gradual shift (repositioning), as in the prior art.

Der Erfindungsgegenstand der vorliegenden Erfindung ergibt sich nicht nur aus dem Gegenstand der einzelnen Patentzansprüche, sondern auch aus der Kombination der einzelnen Patentzansprüche untereinander.The subject matter of the present invention results not only from the subject matter of the individual patent claims, but also from the combination of the individual patent claims with one another.

Alle in den Unterlagen, einschließlich der Zusammenfassung, offenbarten Angaben und Merkmale, insbesondere die in den Zeichnungen dargestellte räumliche Ausbildung werden als erfindungswesentlich beansprucht, soweit sie einzeln oder in Kombination gegenüber dem Stand der Technik neu sind.All information and features disclosed in the documents, including the summary, in particular the spatial design shown in the drawings are claimed as essential to the invention, insofar as they are new to the prior art, individually or in combination.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellende Zeichnungen näher erläutert. Hierbei gehen aus den Zeichnungen und ihrer Beschreibung weitere wesentliche Merkmale und Vorteile der Erfindung hervor.The invention is explained in more detail below with the aid of drawings which illustrate only one embodiment. Further essential features and advantages of the invention emerge from the drawings and their description.

Gemäss den Figuren 1 und 2 besteht das Fahrgerüst 1 im wesentlichen aus einer Basisbühne 2, die ihrerseits aus horizontalen - einen gegenseitigen Abstand bildenden - Traversen 5 besteht, wobei in den Figuren 1 und 2 lediglich die jeweils vorderste Traverse 5 erkennbar ist.According to FIGS. 1 and 2, the mobile scaffold 1 essentially consists of a base platform 2, which in turn consists of horizontal crossbeams 5 which form a mutual distance, only the foremost crossbeam 5 being visible in FIGS. 1 and 2.

Die beiden Traversen 5 sind über eine sogenannte Einstiegsbühne 3 miteinander verbunden.The two trusses 5 are connected to one another via a so-called access platform 3.

An jeder Traverse 5 ist ein Verstellfuss 6 befestigt, der an seiner Unterseite feststellbare Rollen 7 aufweisen kann.An adjustment foot 6 is attached to each cross member 5 and can have rollers 7 that can be locked on its underside.

Zum Aufbau des Fahrgerüstes ist es bekannt, auf den Traversen 5 sogenannte Gerüstrahmen 4 zu befestigen, wobei die Einstiegsbühne 3 und die Gerüstrahmen 4 mit erfindungsgemässen Klemmbeschlägen 8 an den Traversen 5 befestigt werden.For the construction of the mobile scaffolding, it is known to fasten so-called scaffold frames 4 on the cross beams 5, wherein the access platform 3 and the scaffold frames 4 are fastened to the cross beams 5 with clamping fittings 8 according to the invention.

Die weitere Ausgestaltung des Arbeitsgerüstes ist in den Zeichnungen nicht dargestellt.
Oberhalb der Einstiegsbühne 3 sind dann an den Gerüstrahmen 4 weitere Arbeitsbühnen eingehängt, wobei ebenfalls die erfindungsgemässen Klemmbeschläge 8 verwendet werden können.The further design of the scaffolding is not shown in the drawings.
Further work platforms are then suspended above the scaffolding platform 3 on the scaffold frames 4, it also being possible to use the clamp fittings 8 according to the invention.

Wichtig ist, daß eine stufenlose Verschiebung der Gerüstrahmen 4 und der Einstiegsbühne 3 entlang der Traversen 5 in Pfeilrichtung 9 stattfinden kann. Hierzu werden die erfindungsgemässen Klemmbeschläge 8 gelöst; es erfolgt dann die Verschiebung der genannten Teile gemäss Figur 2 und die Klemmbeschläge 8 werden dann wieder festgespannt.It is important that the scaffold frame 4 and the access platform 3 can be moved continuously along the cross members 5 in the direction of the arrow 9. For this purpose, the clamp fittings 8 according to the invention are released; the mentioned parts are then shifted according to FIG. 2 and the clamping fittings 8 are then tightened again.

Wichtig ist im übrigen gemäss den Figuren 3 bis 5, daß mit Hilfe der erfindungsgemässen Klemmbeschläge das gesamte Arbeitsgerüst von einer einzigen Person aufgebaut werden kann.It is important, moreover, according to FIGS. 3 to 5, that the entire work scaffold can be erected by a single person with the aid of the clamp fittings according to the invention.

Hierzu wird gemäss Figur 3 zunächst die Einstiegsbühne 3 mit den daran befestigten Klemmbeschlägen 8 an der einen Seite der Traverse 5 eingehängt und befestigt, wobei die hier an der gegenüberliegenden Seite befindlichen Klemmbeschläge 8 frei bleiben.For this purpose, according to FIG. 3, the access platform 3 with the clamp fittings 8 attached to it is first attached to one side of the crossmember 5 and fastened, the clamp fittings 8 located here on the opposite side remaining free.

Gemäss Figur 4 wird dann die gegenüberliegende Traverse mit den daran befestigten Verstellfüssen 6 herangefahren und die Einstiegsbühne 3 wird angehoben und die Klemmbeschläge 8 werden in geöffnetem Zustand um die Traverse 5 herumgelegt und festgespannt, so daß sich der Zustand nach Figur 3 ergibt.According to FIG. 4, the opposite traverse is then moved up with the adjustment feet 6 attached to it and the access platform 3 is raised and the clamping fittings 8 are placed around the crossbar 5 and tightened in the open state, so that the state according to FIG. 3 results.

Auf diese Weise kann von einer einzigen Person das Arbeitsgerüst weiter aufgebaut werden, indem z.B. nach der Anbringung der Gerüstrahmen 4, die ebenfalls mit den Klemmbeschlägen 8 an den Traversen 5 befestigt werden, weitere Diagonalstreben 11 an den Gerüstrahmen 4 befestigt werden.In this way, the work scaffold can be further built by a single person, for example after the attachment of the scaffold frames 4, which are also fastened to the cross members 5 with the clamping fittings 8, further diagonal struts 11 are fastened to the scaffold frames 4.

Gemäss Figur 6 ist an der Stirnseite der jeweiligen Einstiegsbühne 3 der Klemmbeschlag 8 mit Hilfe von Laschen 13 befestigt. Die Laschen 13 sind hierbei angeschweisst oder angeschraubt oder genietet.According to FIG. 6, the clamp fitting 8 is fastened to the end face of the respective entry platform 3 with the aid of tabs 13. The tabs 13 are welded or screwed or riveted.

Der Klemmbeschlag besteht im wesentlichen aus den Laschen 13, die werkstoffeinstückig oder über entsprechende Verbindungsstellen mit dem vertikalen Schenkel 14 des Klemmbeschlages verbunden sind. Der Schenkel 14 ist mit einem horizontalen Schenkel 15 verbunden, an dessen äusserem, freien Ende ein Drehbolzen 17 befestigt ist, an dem schwenkbar ein Schließteil 16 angeordnet ist. An der Unterseite des Schließteils 16 ist hierbei ein Schlitz 20 angeordnet.The clamp fitting essentially consists of the tabs 13, which are connected in one piece with the material or via corresponding connecting points to the vertical leg 14 of the clamp fitting. The leg 14 is connected to a horizontal leg 15, on the outer, free end of which a pivot pin 17 is fastened, on which a locking part 16 is pivotally arranged. A slot 20 is arranged on the underside of the closing part 16.

Am Schenkel 14 ist ein weiterer Drehbolzen 18 angeordnet, an dem das Drehlager für eine Klemmschraube 22 ausgebildet ist. Diese erstreckt sich unterhalb der Traverse 5 und ist mit einer Ringmutter 19 versehen.A further pivot pin 18 is arranged on the leg 14, on which the pivot bearing for a clamping screw 22 is formed. This extends below the cross member 5 and is provided with a ring nut 19.

Zur Befestigung des Klemmbeschlages wird somit das Schließteil 16 um den Drehbolzen 17 verdreht, bis es sich an der Aussenseite der Traverse 5 anlegt. Es wird dann die Klemmschraube 22 um den Drehbolzen 18 verschwenkt, bis die Schraube in den Schlitz 20 im Schenkel 16 eintritt, und es wird dann die Ringmutter 19 festgedreht, so daß sich das Schließteil 16 klemmend an der Aussenseite der Traverse 5 anlegt und gleichzeitig der Schenkel 14 den entsprechenden Gegendruck erzeugt.To fasten the clamp fitting, the closing part 16 is thus rotated about the pivot pin 17 until it bears against the outside of the cross member 5. The clamping screw 22 is then pivoted about the pivot pin 18 until the screw enters the slot 20 in the leg 16, and the ring nut 19 is then tightened so that the locking part 16 clamps against the outside of the cross member 5 and at the same time the leg 14 generates the corresponding counter pressure.

Es erfolgt somit ein Klemm- und gleichzeitig ein Formschluß, weil die genannten Schenkel 14,15,16 der Formgebung der Traverse 5 angepasst sind.There is thus a clamping and at the same time a form fit because the legs 14, 15, 16 mentioned are adapted to the shape of the crossmember 5.

Es wurde bereits schon eingangs darauf hingewiesen, daß die Erfindung nicht auf ein Vierkantprofil einer Traverse beschränkt ist. Es können auch andere Formgebungen der Schenkel 14,15,16 verwendet werden, um stets eine formschlüssige Anlage an der zugeordneten Traverse 5 zu erreichen.It has already been pointed out at the beginning that the invention is not restricted to a square profile of a traverse. Other shapes of the legs 14, 15, 16 can also be used in order to always achieve a positive fit on the associated cross member 5.

Im übrigen ist aus den Zeichnungen noch erkennbar, daß die als Vierkantprofil ausgebildete Traverse 5 an den Verstellfüssen 6 mit jeweils vertikalen Rundteilen 12 verbunden ist, wobei jedes Rundteil als Hülse ausgebildet ist, durch welches sich eine Spindel 10 hindurch erstreckt. Die Spindel 10 ist mit einem Rollenlager 23 fest verbunden. Auf der Spindel 10 sitzt drehbar eine Spindelmutter 21, so daß stufenlos die Höhe des Rollenlagers 23 und damit der Rolle 7 verstellt werden kann.Moreover, it can still be seen from the drawings that the cross member 5, which is designed as a square profile, is connected to the adjustable feet 6 with vertical round parts 12, each round part being designed as a sleeve, through which a spindle 10 extends. The spindle 10 is firmly connected to a roller bearing 23. A spindle nut 21 is rotatably seated on the spindle 10, so that the height of the roller bearing 23 and thus the roller 7 can be adjusted continuously.
