In DE 888 161 C ist ein aus einzelnen vorher gefertigten Rahmen gebildetes Rohrbaugerüst, insbesondere zur Aufnahme und Unterstützung von Arbeitsbühnen, beschrieben, bei dem die einzelnen aus je zwei Standbäumen und einem oder mehreren Querstäben gebildeten Rahmen mittels mindestens über zwei Felder durchlaufender Streichbäume und Klemmvorrichtungen miteinander verbunden werden. Das Rohrbaugerüst ist gekennzeichnet durch die Vereinigung durchlaufender Streichbäume mit in den inneren oberen Ecken. jeder Rahmeneinheit am Rahmen ortsfest angebrachten Klemmvorrichtungen und mit über die Streichbäume gelegten rohrförmigen Riegeln, deren Oberkanten mit den Oberkanten der Rahmenquerstäbe zur Aufnahme einer Arbeitsbühne in einer Ebene liegen. In US 3,395,501 ist ein Hebeturm beschrieben, der aus trennbaren Rahmeneinheiten besteht, die so miteinander verbunden sind, dass sie eine im Wesentlichen starre Struktur bilden, wobei die Einheiten jeweils umfassen:

  1. (1) dreieckige Einheiten, die aufweisen

From the EP 2 411 598 B1 a scaffolding tower with a scaffolding frame for use as a shoring has become known, which is particularly well suited to climbing the scaffolding tower by means of ladders formed on the scaffolding frame. In these known scaffolding frames, the rungs of the ladders are formed in particular by the horizontal arms on the vertical frames. Climbing a scaffolding tower is made easier for unauthorized persons. In DE 888 161 C describes a tubular scaffolding formed from individual, previously manufactured frames, in particular for accommodating and supporting work platforms, in which the individual frames, each formed from two uprights and one or more crossbars, are connected to one another by means of matchsticks and clamping devices running through at least two fields. The tubular scaffolding is characterized by the union of continuous matchsticks with in the inner upper corners. each frame unit on the frame stationary mounted clamping devices and laid over the backrests tubular bars whose upper edges with the upper edges of Frame crossbars for accommodating a work platform lie in one plane. In U.S. 3,395,501 describes a lifting tower consisting of separable frame units joined together to form a substantially rigid structure, the units each comprising:
  1. (1) triangular units that have
    • a) tubular legs at opposite ends for receiving connecting sprockets,
    • (b) rings with their axes parallel to and spaced from the axes of the legs,
    • (c) arms projecting to one side from the legs, the ends of the arms and rings being connected together at the remote ends of the triangles, the rings being adapted to align respectively with the tubular openings in legs of adjacent units to use through them
  2. (2) pinions connecting the vertical legs of each unit to the apex rings of adjacent units,
  3. (3) side walls each comprising
    • (a) spaced vertical legs,
    • b) horizontal beams connecting the legs into a frame, and
    • (c) diagonal braces fixed between the girders and legs to give greater rigidity to the structure, and
    • (d) the legs being hollow at their ends to receive sprockets by which they are connected to adjacent units.

Es ist daher Aufgabe der Erfindung, einen Gerüstrahmen für einen Gerüstturm bereitzustellen, durch welchen ein Klettern über den oder die Gerüstrahmen an dem Gerüstturm verhindert oder zumindest erschwert wird.It is therefore the object of the invention to provide a scaffolding frame for a scaffolding tower, by means of which climbing over the scaffolding frame or frames on the scaffolding tower is prevented or at least made more difficult.

Die Aufgabe wird durch eine Anordnung gemäß Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den rückbezogenen Unteransprüchen.The object is achieved by an arrangement according to claim 1. Advantageous refinements result from the dependent claims.

Offenbarung der ErfindungDisclosure of Invention

Erfindungsgemäß weist der Gerüstrahmen ein erstes Gerüstrohr und ein zweites Gerüstrohr auf. Das zweite Gerüstrohr ist zu dem ersten Gerüstrohr parallel und von diesem beabstandet angeordnet. Der Gerüstrahmen weist eine erste Querstrebe auf. Diese ist zwischen dem ersten Gerüstrohr und dem zweiten Gerüstrohr senkrecht und horizontal zu diesen Gerüstrohren ausgerichtet angeordnet. Der Gerüstrahmen ist dadurch gekennzeichnet, dass eine zweite Querstrebe mit einem ersten Ende an dem ersten Gerüstrohr und mit einem zweiten Ende an der ersten Querstrebe angeordnet und fixiert ist. Dabei ist zwischen der zweiten Querstrebe und dem ersten Gerüstrohr ein erster spitzer Winkel ausgebildet. Eine dritte Querstrebe ist mit einem dritten Ende an dem zweiten Gerüstrohr und mit einem vierten Ende an der zweiten Querstrebe angeordnet und fixiert. Hierbei ist zwischen der dritten Querstrebe und dem zweiten Gerüstrohr ein zweiter spitzer Winkel ausgebildet. Das zweite und vierte Ende der Querstreben sind in der Ebene des Gerüstrahmens angeordnet. Innerhalb des Gerüstrahmens weist das zweite Ende der zweiten Querstrebe einen ersten Abstand zu dem zweiten Gerüstrohr auf. Das zweite Ende der zweiten Querstrebe ist bei dem erfindungsgemäßen Gerüstrahmen von dem zweiten Gerüstrohr beabstandet. Das vierte Ende der dritten Querstrebe weist einen zweiten Abstand zu dem ersten Gerüstrohr auf und ist stets vom ersten Gerüstrohr beabstandet.According to the invention, the scaffolding frame has a first scaffolding tube and a second scaffolding tube. The second scaffold tube is parallel to and spaced from the first scaffold tube. The scaffolding frame has a first cross brace. This is arranged between the first scaffolding tube and the second scaffolding tube, aligned perpendicularly and horizontally to these scaffolding tubes. The scaffolding frame is characterized in that a second cross brace is arranged and fixed with a first end on the first scaffold tube and with a second end on the first cross brace. A first acute angle is formed between the second cross brace and the first scaffold tube. A third cross brace is arranged and fixed with a third end on the second scaffold tube and with a fourth end on the second cross brace. Here, a second acute angle is formed between the third cross brace and the second scaffold tube. The second and fourth ends of the cross braces are located in the plane of the scaffolding frame. Inside the scaffold frame, the second end of the second cross brace has a first spacing from the second scaffold tube. In the scaffolding frame according to the invention, the second end of the second cross brace is at a distance from the second scaffolding tube. The fourth end of the third cross brace is at a second distance from the first scaffold tube and is always spaced from the first scaffold tube.

Insbesondere sind bei dem Gerüstrahmen das erste und das zweite Gerüstrohr vertikal und die erste Querstrebe horizontal ausgerichtet, besonders im montierten Zustand des Gerüstrahmens. Die zweite und dritte Querstrebe sind in Bezug auf die erste Querstrebe und die Gerüstrohre schräg bzw. schief oder geneigt verlaufend ausgerichtet.In particular, in the case of the scaffolding frame, the first and the second scaffolding tube are aligned vertically and the first cross brace is aligned horizontally, particularly when the scaffolding frame is in the assembled state. The second and The third cross brace are aligned in relation to the first cross brace and the scaffolding tubes at an angle or at an angle.

Durch diese schräge Anordnung der zweiten Querstrebe und der dritten Querstrebe ist sichergestellt, dass keine Person bei einem Gerüstturm, welcher erfindungsgemäße Gerüstrahmen aufweist, an diesen Gerüstrahmen klettern kann. Die zweite und dritte Querstrebe lassen sicht nicht als Leiter verwenden, weil keine geeignete Trittfläche ausgebildet ist. Beim Auftritt in den Verbindungsbereich Querstrebe/Gerüstrohr wird sich ein Arbeitsschuh eines Gerüstbauers verkeilen. Der Gerüstbauer ist somit gezwungen, sicherheitstechnisch zugelassene Mittel und Ausrüstungen für den Auf- und Abstieg am Gerüstturm zu verwenden. Die Absturzgefahr, die bei herkömmlichen Gerüsttürme aufgrund von nicht regelkonformem Auf- und Abstieg am fertigen Turm besteht, wird somit wesentlich reduziert bzw. ausgeräumt.This oblique arrangement of the second cross brace and the third cross brace ensures that nobody can climb onto a scaffolding tower which has a scaffolding frame according to the invention. The second and third cross braces cannot be used as a ladder because there is no suitable step surface. A scaffolder's work shoe will become wedged when stepping into the area where the cross brace/scaffolding tube connects. The scaffolder is therefore forced to use safety-approved means and equipment for climbing up and down the scaffolding tower. The risk of falling, which occurs with conventional scaffolding towers due to non-compliant ascent and descent on the finished tower, is thus significantly reduced or eliminated.

Erfindungsgemäße Gerüstrahmen können an sich gegenüberliegenden Seiten eines Gerüstturms als Vertikalrahmen vertikal übereinander aufeinander gesteckt angeordnet sein. Dabei lassen sich die beiden auf den gegenüberliegenden Seiten auf einer Ebene angeordneten Vertikalrahmen jeweils durch an Rosetten befestigte, senkrecht zu den Vertikalrahmen ausgerichtete Horizontalriegel miteinander verbinden, insbesondere an den in vertikaler Richtung oberen und unteren Enden der Vertikalrahmen. Zur Aussteifung können aus dem Stand der Technik bekannte Bauelemente verwendet werden. Unter anderem sind hierfür Diagonalelemente, insbesondere Riegeldiagonalen oder Gerüstrahmen geeignet, welche jeweils an einem Horizontalriegel an einer unteren Seite eines Vertikalrahmens und an dem nächsthöheren Horizontalriegel auf der gegenüberliegenden Seite des Gerüstturms befestigt werden. Die Muffen der Gerüstrahmen sind in einer Art und Weise ausgebildet, dass Sicherheitshaken entfallen können. Ebenfalls können an den Gerüstrohren nur geringer dimensionierte, Befestigungspositionen zur Verfügung stellende Verbindungselemente, beispielsweise sogenannte ¾-Rosetten oder Anschlussknoten ausgebildet sein. Über diese beiden Maßnahmen lässt sich das Gewicht des erfindungsgemäßen Gerüstrahmens verringern und Material für die Fertigung des Gerüstrahmens wird eingespart.Scaffolding frames according to the invention can be arranged on opposite sides of a scaffolding tower as vertical frames, plugged one on top of the other vertically. The two vertical frames arranged on the opposite sides on one level can be connected to one another by horizontal bars attached to rosettes and aligned perpendicularly to the vertical frames, in particular at the upper and lower ends of the vertical frames in the vertical direction. Components known from the prior art can be used for stiffening. Among other things, diagonal elements are suitable for this, in particular bar diagonals or scaffolding frames, which are each fastened to a horizontal bar on a lower side of a vertical frame and to the next higher horizontal bar on the opposite side of the scaffolding tower. The sleeves of the scaffolding frames are designed in such a way that safety hooks can be omitted. Also can on the scaffold tubes connecting elements that are only smaller in dimension and provide fastening positions, for example so-called ¾ rosettes or connection nodes. With these two measures, the weight of the scaffolding frame according to the invention can be reduced and material for the production of the scaffolding frame is saved.

Erfindungsgemäß ist ein vierter spitzer Winkel und zu diesem vierten spitzen Winkel ein fünfter stumpfer Winkel als Ergänzungswinkel zwischen der dritten Querstrebe und der zweiten Querstrebe ausgebildet. Vorteilhaft ist ein dritter spitzer Winkel zwischen der zweiten Querstrebe und der ersten Querstrebe ausgebildet. Durch diese Wahl der Winkel lässt sich die erfindungsgemäße Ausrichtung und Anordnung der Enden der zweiten und dritten Querstrebe auf einfache Weise bewirken.According to the invention, a fourth acute angle and, for this fourth acute angle, a fifth obtuse angle are formed as a supplementary angle between the third cross brace and the second cross brace. A third acute angle is advantageously formed between the second cross brace and the first cross brace. The alignment and arrangement of the ends of the second and third cross braces according to the invention can be brought about in a simple manner by this choice of angle.

Eine weitere Ausgestaltung des Gerüstrahmens ist dadurch gekennzeichnet, dass der erste spitze Winkel Werte im Bereich von 57° bis 58°, insbesondere einen Wert von 57,14°, aufweist und/oder der zweite spitze Winkel Werte im Bereich von 73° bis 74°, insbesondere einen Wert von 73,15°, aufweist.A further configuration of the scaffolding frame is characterized in that the first acute angle has values in the range from 57° to 58°, in particular a value of 57.14°, and/or the second acute angle has values in the range from 73° to 74° , in particular a value of 73.15°.

Ferner kann der dritte spitze Winkel Werte im Bereich von 32° bis 33° aufweisen, insbesondere einen Wert von 32,86°, und/oder der vierte spitze Winkel Werte im Bereich von 49° bis 50°, insbesondere einen Wert von 49,71°, aufweisen und der fünfte stumpfe Winkel als Ergänzungswinkel einen Wert von 130° bis 131°, insbesondere einen Wert von 130,29°.Furthermore, the third acute angle can have values in the range from 32° to 33°, in particular a value of 32.86°, and/or the fourth acute angle can have values in the range from 49° to 50°, in particular a value of 49.71 °, and the fifth obtuse angle as a supplementary angle has a value of 130° to 131°, in particular a value of 130.29°.

Durch diese Wahl der Winkel wird ein Hindurchfallen eines Normkörpers durch den Gerüstrahmen bei einer Länge der Gerüstrohre von etwa 1 m sicher verhindert.This choice of angle reliably prevents a standard body from falling through the scaffolding frame with a scaffolding tube length of around 1 m.

In einer vorteilhaften Ausgestaltung des Gerüstrahmens ist die erste, zweite und/oder dritte Querstrebe jeweils als Kreishohlprofil ausgebildet. Grundsätzlich sind die Querstreben als Hohlprofil, bevorzugt mit einer Konfiguration als Rechteck-, Quadrat- oder Kreishohlprofil ausgebildet. Die Profile können dabei gleiche oder unterschiedliche Konfigurationen, Dimensionierungen und/oder Durchmesser aufweisen. Denkbar sind auch Kombinationen der Profile oder Profildimensionen bzw. -durchmesser. Durch geeignete Auswahl der Profile oder Profilkombinationen kann eine Anpassung oder Optimierung des Gewichts und/oder der statischen Eigenschaften der Rahmen vorgenommen werden.In an advantageous embodiment of the scaffolding frame, the first, second and/or third cross brace is each designed as a circular hollow profile. In principle, the transverse struts are designed as a hollow profile, preferably with a configuration as a rectangular, square or circular hollow profile. The profiles can have the same or different configurations, dimensions and/or diameters. Combinations of the profiles or profile dimensions or diameters are also conceivable. The weight and/or the static properties of the frame can be adjusted or optimized by suitably selecting the profiles or profile combinations.

Ferner können die erste und/oder zweite und/oder dritte Querstrebe ein rechteckiges oder quadratisches Profil aufweisen. Ein rechteckiges oder quadratisches Profil ermöglicht durch die relativ große Kontaktfläche eine stabile Anordnung der Querstreben an den Gerüstrohren oder anderen Bauelementen, insbesondere, wenn diese Bauteile ebenfalls ein rechteckiges oder quadratisches Profil aufweisen.Furthermore, the first and/or second and/or third cross brace can have a rectangular or square profile. Due to the relatively large contact surface, a rectangular or square profile enables a stable arrangement of the cross braces on the scaffolding tubes or other components, especially if these components also have a rectangular or square profile.

Eine vorteilhafte Ausgestaltung des Gerüstrahmens ist dadurch gekennzeichnet, dass zumindest eine der Querstreben aus einem anderen Material als die anderen Querstreben und/oder die Gerüstrohre ausgebildet ist. Durch Veränderung des Materials kann eine optimale Anpassung an die Anforderungen hinsichtlich des Gewichts und der Stabilität des Gerüstrahmens erfolgen. Für die Gerüstrohre kann insbesondere Baustahl verwendet werden, bevorzugt die Stahlsorten S235, S355 und/oder S420 oder Kombinationen daraus.An advantageous embodiment of the scaffolding frame is characterized in that at least one of the cross braces is made of a different material than the other cross braces and/or the scaffold tubes. By changing the material, an optimal adaptation to the requirements in terms of weight and stability of the scaffolding frame can be made. Structural steel, in particular, can be used for the scaffold tubes, preferably the steel grades S235, S355 and/or S420 or combinations thereof.

Eine weitere Ausgestaltung des Gerüstrahmens ist dadurch gekennzeichnet, dass zumindest eine der Querstreben eine andere Dicke der Rohrwandung aufweist als die anderen Querstreben und/oder die Gerüstrohre. Wie bei der Auswahl des Materials für den Gerüstrahmen kann auch durch die Dicke der jeweiligen Rohrwandung eine Anpassung des Gerüstrahmens an die Anforderungen hinsichtlich des Gewichtes und der Stabilität bewirkt werden.A further embodiment of the scaffolding frame is characterized in that at least one of the transverse struts has a different tube wall thickness than the other transverse struts and/or the scaffolding tubes. As with the choice of material for the scaffolding frame the thickness of the respective tube wall can also be used to adapt the scaffolding frame to the requirements in terms of weight and stability.

Bei einer vorteilhaften Ausgestaltung des Gerüstrahmens ist zumindest eine der Querstreben durch Schweißung an den anderen Querstreben und/oder Gerüstrohren befestigt. Durch eine Schweißung kann die Befestigung der Querstreben auf stabile Weise erfolgen. Vorteilhaft weist der erfindungsgemäße Gerüstrahmen nur sechs Schweißpunkte (Schweißbereiche) auf. Damit kann der erfindungsgemäße Gerüstrahmen "verzugsfreier" hergestellt werden als bekannte Gerüstrahmen mit zahlreicheren Schweißpunkten, da im Verlauf des Schweißvorganges weniger Wärme in das Material des zu erstellenden Gerüstrahmens eingetragen wird.In an advantageous embodiment of the scaffolding frame, at least one of the cross braces is attached to the other cross braces and/or scaffold tubes by welding. Welding allows the cross braces to be attached in a stable manner. Advantageously, the scaffolding frame according to the invention has only six spot welds (weld areas). The scaffolding frame according to the invention can thus be manufactured "with less distortion" than known scaffolding frames with more welding points, since less heat is introduced into the material of the scaffolding frame to be created during the course of the welding process.

Eine weitere Ausgestaltung des Gerüstrahmens ist dadurch gekennzeichnet, dass die zweite Querstrebe und die dritte Querstrebe verschiedene Breiten und/oder Höhen oder Durchmesser aufweisen. Hierdurch kann unter anderem der Materialverbrauch bei der Herstellung des Rahmens aber auch dessen statische Eigenschaft optimiert werden.A further embodiment of the scaffolding frame is characterized in that the second cross brace and the third cross brace have different widths and/or heights or diameters. In this way, among other things, the material consumption in the production of the frame but also its static properties can be optimized.

In Fig. 1 ist eine Seitenansicht auf den erfindungsgemäßen Gerüstrahmen 10 gezeigt. Der Gerüstrahmen 10 weist ein erstes Gerüstrohr 12 und ein zweites Gerüstrohr 14 auf. Das zweite Gerüstrohr 14 ist parallel zu und beabstandet von dem ersten Gerüstrohr 12 angeordnet. Zwischen dem ersten Gerüstrohr 12 und dem zweiten Gerüstrohr 14 ist eine erste Querstrebe 16 zur Aussteifung angeordnet und insbesondere angeschweißt. Diese erste Querstrebe 16 verläuft senkrecht zu dem ersten Gerüstrohr 12 und dem zweiten Gerüstrohr 14. Eine zweite Querstrebe 18 ist mit einem ersten Ende 20 an dem ersten Gerüstrohr 12 und mit einem zweiten Ende 22 an der ersten Querstrebe 16 angeordnet und insbesondere angeschweißt.In 1 a side view of the scaffolding frame 10 according to the invention is shown. The scaffolding frame 10 has a first scaffolding tube 12 and a second scaffolding tube 14 . The second scaffold tube 14 is arranged parallel to and spaced apart from the first scaffold tube 12 . Between the first scaffolding tube 12 and the second scaffolding tube 14, a first transverse strut 16 is arranged and in particular welded on for reinforcement. This first cross brace 16 runs perpendicularly to the first scaffold tube 12 and the second scaffold tube 14. A second cross brace 18 is arranged with a first end 20 on the first scaffold tube 12 and with a second end 22 on the first cross brace 16 and in particular is welded.

Eine dritte Querstrebe 26 ist zur Stabilisierung mit einem dritten Ende 28 an dem zweiten Gerüstrohr 14 und mit einem vierten Ende 30 an der zweiten Querstrebe 18 angeordnet und insbesondere angeschweißt.

The fourth end 30 of the third cross member 26 has within the Scaffolding frame 10 has a second spacing 34 from the first scaffolding tube 12 . As a result, the second crossbar 18 and the third crossbar 26 form an arrangement which resembles the Greek small letter lambda. This arrangement of the second cross brace 18 and the third cross brace 26 ensures that no person can climb onto a scaffolding tower which has a scaffolding frame 10 . The third and fourth crossbars 18, 26 cannot be used as ladder rungs.

Wenn die Questreben 16, 18, 26 insbesondere jeweils durch Anschweißen befestigt werden, weist der Gerüstrahmen insgesamt sechs Schweißpunkte (Schweißflächenbereiche) 36a, 36b, 36c, 36d, 36e, 36f auf.If the transverse struts 16, 18, 26 are fixed by welding, in particular, the scaffolding frame has a total of six welding points (welding surface areas) 36a, 36b, 36c, 36d, 36e, 36f .

With these values of the angles 42a to 42d, with a length of the scaffold tubes of about 1 m, no standard body with a diameter of 470 mm fits through the surfaces 44a, 44b, 44c , which are between the cross braces 16, 18, 26 and the scaffold tubes 12, 14 are trained.

Die erste, zweite und dritte Querstrebe 16, 18, 26 sind als Rohr ausgebildet. Hierbei können sie vorzugsweise ein rechteckiges Profil aufweisen. Die Breiten und Höhen der Querstreben 16, 18, 26 können hierbei verschieden sein. Insbesondere können bei der zweiten und dritten Querstrebe 18, 26 die Höhe 20 mm und die Breite 30 mm oder 40 mm betragen. So kann die dritte Querstrebe 26 eine kleinere Breite aufweisen als die zweite Querstrebe 18. Bei der ersten Querstrebe 16 kann die Höhe 60 mm und die Breite 30 mm betragen.The first, second and third cross braces 16, 18, 26 are designed as tubes. Here they can preferably have a rectangular profile. The widths and heights of the cross braces 16, 18, 26 can be different. In particular, the height of the second and third cross braces 18, 26 can be 20 mm and the width can be 30 mm or 40 mm. Thus, the third crossbar 26 can have a smaller width than the second crossbar 18. In the case of the first crossbar 16, the height can be 60 mm and the width can be 30 mm.

Die erste, zweite und dritte Querstrebe 16, 18, 26 können untereinander und/oder im Vergleich zu den Gerüstrohren 12, 14 unterschiedliche Materialien aufweisen. Insbesondere kann hierbei Stahl der Sorte S235, S355 und/oder S420 verwendet werden, ohne die Erfindung hierauf zu beschränken. Dabei können die Querstreben 16, 18, 26 unterschiedliche Dicken ihrer jeweiligen Rohrwände und/oder andere Dicken ihrer jeweiligen Rohrwand als die Gerüstrohre 12, 14 aufweisen. Hierdurch läßt sich der Gerüstrahmen 10 mit unterschiedlichem Gewicht herstellen.The first, second and third cross braces 16, 18, 26 can have different materials from one another and/or from the scaffolding tubes 12, 14. In particular, steel of the S235, S355 and/or S420 grade can be used here without restricting the invention thereto. The transverse struts 16, 18, 26 can have different thicknesses of their respective tube walls and/or different thicknesses of their respective tube walls than the scaffolding tubes 12, 14. As a result, the scaffolding frame 10 can be produced with different weights.
