Abstract
Description
Die Erfindung betrifft ein Gerüstrohr nach dem Oberbegriff des Anspruchs 1.The invention relates to a scaffold tube according to the preamble of claim 1.
Gerüstrohre, insbesondere Standrohre oder Geländerpfosten für Baugerüste werden üblicherweise beim Aufbau des Gerüsts aufeinander gesteckt, wobei die Standrohre häufig auch in sogenannte Gerüstrahmen integriert sind. Zum Aufeinanderstecken dieser Gerüstrohre ist das obere Ende mit einem Fortsatz ausgestattet, dessen Außendurchmesser im Wesentlichen dem Innendurchmesser des Gerüstrohres entspricht, so dass das darüber anzuordnende Gerüstrohr auf diesen Fortsatz aufgesteckt werden kann. Dieser Fortsatz wird beispielsweise durch einen eingepressten Rohrverbinder aus Rundrohr gebildet.Scaffolding tubes, especially standpipes or railing posts for Scaffolding is usually used when setting up the scaffolding plugged onto each other, the stanchions often also in so-called scaffold frames are integrated. To the The top end of these scaffolding tubes is put on top of each other an extension equipped, the outer diameter in Essentially the inside diameter of the scaffold tube corresponds, so that the scaffold tube to be arranged above this extension can be plugged on. This extension will for example, by a pressed-in pipe connector Round tube formed.
Bislang müssen bei Baugerüsten mit derartigen Gerüstrohren stets Rohre der gleichen Wandstärke verwendet werden, um die Passgenauigkeit der Steckverbindung zu gewährleisten.So far, scaffolding with such scaffolding tubes always pipes of the same wall thickness are used to the To ensure a precise fit of the plug connection.
Vielfach ist es jedoch wünschenswert, beispielsweise zur Einsparung von Material und/oder Gewicht, dort dünnwandige Rohre zu verwenden, wo dies aufgrund der zu erwartenden Belastungen grundsätzlich möglich ist. Die Kombination herkömmlicher Gerüstrohre mit derartigen leichteren, dünnwandigeren Rohren ist bislang nicht möglich, da sich hierdurch die Zentrierung der Gerüstrohre verschlechtert und sich die Schiefstellung der Gerüstrohre bei gleichem Außendurchmesser in Folge des größeren Innendurchmesser vergrößert.However, it is often desirable, for example for Saving material and / or weight, thin-walled there Use pipes where this is due to the expected In principle, loads are possible. The combination conventional scaffolding tubes with such lighter, So far, thin-walled pipes have not been possible because this worsens the centering of the scaffolding tubes and the skewing of the scaffold tubes is the same Outer diameter due to the larger inner diameter increased.
Aufgabe der Erfindung ist es daher, ein Gerüstrohr vorzuschlagen, bei dem leichtere, dünnwandigere Rohre in Kombination mit bisherigen Gerüstrohren bzw. Standrohren unter Vermeidung der oben angeführten Nachteile einsetzbar sind.The object of the invention is therefore a scaffold tube to propose lighter, thinner walled tubes in Combination with previous scaffold tubes or standpipes can be used while avoiding the disadvantages mentioned above are.
Diese Aufgabe wird ausgehend von einem Gerüstrohr der einleitend genannten Art durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This task is based on a scaffold tube type mentioned in the introduction by the characteristic features of claim 1 solved.
Durch die in den Unteransprüchen genannten Maßnahmen sind vorteilhafte Ausführungen und Weiterbildungen der Erfindung möglich.By the measures mentioned in the subclaims advantageous embodiments and developments of the invention possible.
Dementsprechend zeichnet sich ein erfindungsgemäßes Gerüstrohr dadurch aus, dass in dem zum Aufstecken verwendbaren Endbereich des Rohres eine Querschnittsverjüngung vorgesehen ist.Accordingly, one according to the invention is distinguished Scaffold tube characterized in that in which to attach usable end area of the tube one Cross-sectional taper is provided.
Diese Querschnittsverjüngung ermöglicht den Formschluss mit Rohrverbindern bisheriger Gerüstrohre, so dass ein dünnwandigeres Gerüstrohr mit gleichem Außenumfang zuverlässig in der Steckverbindung gut zentriert und gerade ausgerichtet ist und eine entsprechende Kippstabilität aufweist.This tapering of the cross-section enables the positive locking with Pipe connectors of previous scaffold tubes, so that a thinner-walled scaffold tube with the same outer circumference Reliable, well centered and straight in the connector is aligned and a corresponding tilt stability having.
In einer vorteilhaften Ausführungsform der Erfindung wird die Querschnittsverjüngung durch eine Einprägung vorgenommen. In an advantageous embodiment of the invention, the Cross-sectional taper made by embossing.
Eine solche Einprägung ist besonders einfach herzustellen und erfordert insbesondere keinen zusätzlichen Materialaufwand.Such an impression is particularly easy to manufacture and in particular requires no additional material.
Vorteilhafterweise wird die Querschnittsverjüngung ringförmig ausgebildet. Eine ringförmige Ausbildung der Querschnittsverjüngung ergibt bei der Einprägung gleichmäßig umfangsseitig einwirkende Kräfte, so dass die Einprägung durch entsprechende Prägestempel von außen ohne weitere Maßnahmen im Inneren des Rohres anzubringen sind.The cross-sectional taper is advantageously annular educated. An annular formation of the Cross-sectional tapering results in uniform embossing forces acting on the circumference, so that the impression by means of appropriate stamps from the outside without any further Measures must be taken inside the pipe.
Grundsätzlich wären jedoch auch nasenförmige oder rippenförmige umfangseitig verteilte Einprägungen denkbar.Basically, however, would also be nose-shaped or Rib-shaped impressions distributed around the circumference are conceivable.
Vorteilhaferweise wird die Querschnittsverjüngung vom Rand des Gerüstrohres beabstandet angebracht. Somit bleibt der Außenumfang des Rohres in der stirnseitigen Aufstandsfläche erhalten. Zudem ist der Prägevorgang selbst mit einem gewissen Abstand vom Rand des Rohres einfacher zu bewerkstelligen.The cross-sectional taper is advantageously from the edge of the scaffold tube attached spaced. The remains Outer circumference of the tube in the front contact area receive. In addition, the stamping process itself with one certain distance from the edge of the pipe easier accomplish.
Weiterhin ist es von Vorteil, wenn zwei oder mehrere in axialer Richtung voneinander beabstandete Querschnittsverjüngungen vorgesehen sind. Auf diese Weise lässt sich besonders einfach eine große, sogenannte Führungslänge der Steckverbindung erreichen, die wiederum die Kippstabilität bzw. die Güte der Ausrichtung der Steckverbindung beeinflusst.It is also advantageous if two or more in spaced from each other in the axial direction Cross-sectional tapering are provided. In this way it is particularly easy to create a large, so-called Reach guide length of the connector, which in turn the Tilt stability or the quality of the alignment of the Connector affected.
Der Abstand der Querschnittsverjüngungen bzw. die Führungslänge, die dem Abstand der Querschnittsverjüngungen entspricht, wird vorzugsweise an die gewünschte Kippstabilität und/oder die gewünschte Güte der Ausrichtung der Steckverbindung angepasst.The distance of the cross-sectional taper or Guide length, which is the distance of the cross-sectional taper corresponds, is preferably to the desired Tilt stability and / or the desired quality of alignment adapted to the connector.
Anstelle zweier oder mehrerer voneinander beabstandeter Querschnittsverjüngungen wäre auch eine Querschnittsverjüngung denkbar, die sich über einen gewissen Abstand in axialer Richtung erstreckt, der sich wiederum aus der gewünschten Kippstabilität und/oder der gewünschten Güte der Ausrichtung der Steckverbindung ergibt. Grundsätzlich ist eine solche sich längs erstreckende Querschnittsverjüngung ebenfalls ringförmig denkbar, es wären jedoch auch für diese Ausführungsform insbesondere rippenförmige Einprägungen, die umfangsseitig um das Gerüstrohr verteilt sind, von Vorteil. Durch Längsrippen kann zum Beispiel zugleich die Biegesteifigkeit des Rohres im Bereich der Steckverbindung verbessert werden.Instead of two or more spaced apart Cross-sectional tapering would also be one Cross-sectional rejuvenation is conceivable, which extends beyond a certain Distance extends in the axial direction, which in turn extends from the desired tilt stability and / or the desired quality the orientation of the connector results. Basically is such a longitudinally extending cross-sectional taper also conceivable in a ring, but it would also be for this Embodiment in particular rib-shaped impressions that are distributed around the circumference of the scaffold tube, an advantage. Longitudinal ribs, for example, can simultaneously Bending stiffness of the pipe in the area of the plug connection be improved.
Darüber hinaus kann eine sich über eine bestimmte Führungslänge erstreckende Querschnittsverjüngung auch mit Hilfe eines Einlegeteils realisiert werden. Ein solches Einlegeteil kann zur Fixierung beispielsweise verpresst oder verschweißt werden. Ein solches Einlegeteil verursacht zwar einen gewissen Mehraufwand in der Fertigung, es eignet sich jedoch insbesondere in den Anwendungsfällen, in denen eine Erhöhung der Steifigkeit im Bereich der Steckverbindung gewünscht wird.In addition, one can find out about a particular one Cross-sectional taper extending with guide length also with With the help of an insert. Such one Insert can, for example, be pressed or fixed be welded. Such an insert causes a certain additional effort in production, it is suitable however, particularly in the use cases where a Increased rigidity in the area of the plug connection it is asked for.

Die Figuren 1 und 2 zeigen das untere Ende eines Gerüstrohres 1 mit einem Außendurchmesser A und einem Innendurchmesser I. Der Innendurchmesser I ist dabei aufgrund einer dünnwandigeren Ausführungsform des Gerüstrohrs 1 größer als der Innendurchmesser eines herkömmlichen, dickwandigeren Gerüstrohres (nicht näher dargestellt). Dieser Innendurchmesser entspricht hierbei im Wesentlichen dem Außendurchmesser a eines Rohrverbinders 4 (vgl. Figur 3).Figures 1 and 2 show the lower end of a scaffold tube 1 with an outer diameter A and an inner diameter I. The inner diameter I is due to a Thin-walled embodiment of the scaffold tube 1 larger than the inside diameter of a conventional, thick-walled one Scaffold tube (not shown). This The inside diameter corresponds essentially to that Outside diameter a of a pipe connector 4 (see FIG. 3).
Zur Verwendung des dünnwandigeren Gerüstrohres 1 in herkömmlichen Baugerüsten sind erfindungsgemäß zwei ringförmige Querschnittsverjüngungen 2, 3 in den unteren Bereich des Gerüstrohres 1 eingeprägt. Die Querschnittsverjüngungen 2, 3 sind dabei so ausgeformt, dass ihr Innendurchmesser i im Wesentlichen dem Außendurchmesser a des Rohrverbinders 4 entsprechen. Hierdurch ergibt sich beim Aufstecken des Gerüstrohrs 1 auf den Rohrverbinder 4 zunächst einmal eine gute Zentrierung des aufgesteckten Gerüstrohres 1, so dass eine umlaufende Aufstandsfläche der Stirnseite des Gerüstrohres 1 auf dem darunter liegenden Gerüstrohr sichergestellt ist.To use the thin-walled scaffold tube 1 in Conventional scaffolding are two according to the invention annular cross-sectional tapering 2, 3 in the lower Embossed area of the scaffold tube 1. The Cross-sectional tapering 2, 3 are shaped such that their inner diameter i essentially the outer diameter a correspond to the pipe connector 4. This results in First attach the scaffold tube 1 to the tube connector 4 good centering of the attached scaffold tube 1, so that a circumferential contact surface of the front of the Scaffold tube 1 on the scaffold tube underneath is ensured.
Darüber hinaus sind beide Querschnittsverjüngungen 2, 3 über eine Länge F voneinander beabstandet. Dieser Abstand F definiert somit die Führungslänge, von der die Güte der Ausrichtung der Steckverbindung sowie die Kippstabilität abhängt. Über die geeignete Auswahl der Führungslänge F kann in Verbindung mit den Fertigungstoleranzen des Innendurchmessers i der Querschnittsverjüngungen 2, 3 bzw. des Außendurchmessers a des Steckverbinders 4 somit die gewünschte Eigenschaft der Steckverbindung bezüglich der Ausrichtung und Kippstabilität hergestellt werden.In addition, both cross-sectional tapers 2, 3 are over a distance F apart. This distance F thus defines the guide length from which the quality of the Alignment of the plug connection as well as the tilt stability depends. The appropriate selection of the guide length F can in connection with the manufacturing tolerances of the Inner diameter i of the cross-sectional taper 2, 3 or of the outer diameter a of the connector 4 thus the desired property of the connector with respect to Alignment and tilt stability can be produced.
Die unterste Querschnittsverjüngung 2 ist mit einer Höhe H vom unteren Rand des Gerüstrohres 1 beabstandet. Hierdurch wird die Einprägung der Querschnittsverjüngung 2 wesentlich erleichtert. Insbesondere kann hierdurch in Verbindung mit der ringförmigen und damit gleichmäßig über den Umfang verteilten Ausbildung der Querschnittsverjüngungen eine Prägung nur von der Außenseite des Gerüstrohres 1 her vorgenommen werden. Insbesondere sind hierbei die für die Prägung erforderlichen Kräfte umfangsseitig gleich verteilt.The lowest cross-sectional taper 2 has a height H spaced from the lower edge of the scaffold tube 1. hereby the embossing of the cross-sectional taper 2 becomes essential facilitated. In particular, this can be used in conjunction with the ring-shaped and therefore evenly over the circumference distributed training of cross-sectional tapering Embossing only from the outside of the scaffold tube 1 be made. In particular, here are those for Embossing required forces equally distributed around the circumference.
In Figur 3 ist der Einsatz eines erfindungsgemäßen Gerüstrohres 1 bzw. 1' in einem Gerüstrahmen 5 veranschaulicht. Solche Gerüstrahmen 5 werden bevorzugt für den Aufbau der Schmalseite von Baugerüsten verwendet. Der Gerüstrahmen 5 setzt sich aus zwei Standrohren 1, 1' sowie zwei Querriegeln 6, 6' zusammen. Die beiden Standrohre 1, 1' sind an ihrer Oberseite mit Rohrverbindern 4, 4' versehen, so dass beispielsweise ein weiterer baugleicher und nicht näher dargestellter Gerüstrahmen oben aufgesteckt werden kann.In Figure 3 is the use of an inventive Scaffold tube 1 or 1 'in a scaffold frame 5 illustrated. Such scaffolding frames 5 are preferred for used the construction of the narrow side of scaffolding. The Scaffold frame 5 is composed of two standpipes 1, 1 'and two crossbars 6, 6 'together. The two stanchions 1, 1 ' are provided on their top with pipe connectors 4, 4 ', so that, for example, another identical and not closer shown scaffold frame can be plugged on top.
An der Unterseite des Gerüstrahmens 5 sind in den Gerüstrohren 1, 1' die erfindungsgemäßen Querschnittsverjüngungen 2, 3 bzw. 2', 3' eingeformt, was insbesondere in Figur 4 deutlich erkennbar ist. Aus dieser Darstellung geht hervor, dass die Standrohre 1, 1' in Verbindung mit dem Gerüstrahmen 5 hinsichtlich ihrer Ausgestaltung dem Gerüstrohr 1 gemäß den Figuren 1 und 2 entsprechen.At the bottom of the scaffold frame 5 are in the Scaffold tubes 1, 1 'the invention Cross-sectional tapering 2, 3 or 2 ', 3' molded what can be clearly seen in particular in FIG. From this The illustration shows that the standpipes 1, 1 'in Connection with the scaffold frame 5 in terms of their Configuration of the scaffold tube 1 according to FIGS. 1 and 2 correspond.
Die erfindungsgemäße Formgebung ist nicht nur auf Standrohre von Baugerüsten beschränkt. Sie kann bei allen Arten von Gerüstelementen eingesetzt werden, die die Verwendung von Rohren unterschiedlicher Wandstärke bei Steckverbindungen mit Rohrverbindern 4 vorsieht, vor allem bei vertikalen Gerüstelementen, wie Vertikalrahmen, Vertikalstiele, usw. Denkbar ist beispielsweise die oben angeführte Formgebung bei Geländerpfosten, die auf der obersten Arbeitsebene eines Gerüstes als Bestandteil des Seitenschutzes angebracht und dort auf die Rohrverbinder 4 von Standrohren 1 aufgesteckt werden.The shape according to the invention is not only on standpipes limited by scaffolding. It can be used in all types of Scaffolding elements are used, the use of Pipes of different wall thickness with plug connections Pipe connectors 4 provides, especially for vertical Scaffolding elements, such as vertical frames, vertical supports, etc. For example, the shape mentioned above is conceivable Railing posts on the top level of a Scaffold attached as part of the side protection and attached to the pipe connector 4 of standpipes 1 become.
