Description

Die Erfindung betrifft einen Gerüstständer für Systemgerüste zum Einrüsten von Bauwerken, der aus einem Rohr besteht, das scheibenförmige Haltevorrichtungen mit Durchbrüchen zum Einhängen von horizontal und/oder diagonal verlaufenden Gerüstelementen aufweist.The invention relates to a scaffold stand for system scaffolds for installing structures, which consists of a tube having disc-shaped holding devices with openings for suspending horizontally and / or diagonally extending scaffolding elements.

Zum Einrüsten von Bauwerken werden unter anderem sogenannte Systemgerüste (auch Modulgerüste) eingesetzt, bei denen die vertikalen Gerüstständer in bestimmten regelmäßigen Abständen mit festen Anschlussmöglichkeiten für horizontal bzw. diagonal verlaufende Gerüstelemente ausgestattet sind. Diese Gerüstelemente weisen wiederum spezielle, zu den Anschlussmöglichkeiten der vertikalen Tragglieder passende Haltevorrichtungen auf. Als Gerüstelemente sind beispielsweise Quer- und Längsriegel, Diagonalstreben usw. in Gebrauch. In diese Haltevorrichtungen können sodann Anschlussköpfe von Gerüstelementen eingehängt und fixiert werden. In der Regel erfolgt das Fixieren durch Festschlagen der Anschlussköpfe selbst oder von Spannkeilen, die in den Anschlussköpfen bzw. den Anschlusselementen der Riegel integriert sind.Among other things, so-called system scaffoldings (also modular scaffoldings) are used for the installation of structures, in which the vertical scaffold stands are equipped at certain regular intervals with fixed connection possibilities for horizontal or diagonal scaffolding elements. These scaffolding elements in turn have special, suitable for the connection possibilities of the vertical support members holding devices. As scaffolding elements, for example, transverse and longitudinal bars, diagonal struts, etc. in use. In this holding devices can then connecting heads of scaffolding elements be hung and fixed. In general, the fixing takes place by tightening the connection heads themselves or by clamping wedges, which are integrated in the connection heads or the connection elements of the bolt.

Scheibenförmige Haltevorrichtungen an vertikalen Gerüstrohren zum Einhängen von horizontal und/oder diagonal verlaufenden Gerüstelementen sind beispielsweise aus der DE 197 26 950 A1 bekannt. Die bekannten Haltevorrichtungen sind als Scheiben mit Durchbrüchen geformt.Disc-shaped holding devices on vertical scaffolding tubes for suspending horizontally and / or diagonally extending scaffold elements are known, for example, from US Pat DE 197 26 950 A1 known. The known holding devices are shaped as disks with openings.

Die Haltevorrichtungen sind bei bekannten Gerüstrohren in regelmäßigen Abständen an den Gerüstelementen angebracht. In der Regel sind bei Gerüstrohren mit einer Länge von zwei Metern vier Haltvorrichtungen angebracht. Die Haltevorrichtungen erfüllen die an sie gestellten Aufgaben in Bezug auf Stabilität und Sicherheit der Befestigung von Riegeln und Streben. Allerdings besteht ein wesentliches Problem beim Aufbau eines vollständigen Gerüsts darin, dass nach dem Anordnen der Bodenbeläge des zusätzlichen Geschosses zwischen den Gerüstrohren keine Absicherung der Gerüstbauer durch ein Geländer vorhanden ist. Die Geländer werden bei Gerüstrohren der hier betrachteten Art durch Horizontalstreben hergestellt, die an den Haltevorrichtungen benachbarter Rohre befestigt werden. Da die Befestigung der das Geländer bildenden Streben lediglich erfolgen kann, indem der Gerüstbauer die Enden der jeweiligen Streben an die Haltevorrichtungen heranführt und durch Festschlagen der Spannkeile befestigt, ist der Gerüstbauer gezwungen, sich von einem Gerüstrohr zu dem benachbarten Gerüstrohr zu bewegen, bevor ein Geländer fest verankert ist. Hierdurch ist in der Aufbauphase des Gerüstes auf dem jeweils obersten Geschoss tatsächlich keine Absicherung vorhanden, weshalb die Unfallgefahr erhöht ist. Die Berufsgenossenschaften fordern daher, dass ein Begehen der Belagbohlen nur erfolgen darf, wenn bereits ein Geländer montiert ist. Dies ist theoretisch nur dadurch zu gewährleisten, dass der Gerüstbauer bereits von der zum oberen Stockwerk führenden Treppe aus eine das Gelenk bildende Strebe an dem von ihm entfernt angeordneten Gerüstrohr anbringen kann, also über eine Spannweite von zirka 2,5 Metern eine sichere Befestigung vornehmen kann. Dies ist mit den bekannten Gerüstrohren, bei denen die Befestigung an den bekannten scheibenförmigen Haltevorrichtungen erfolgt, nicht zu gewährleisten. Zudem sind die bekannten Gerüstständer mit vier Haltevorrichtungen versehen, die zwar über eine hohe Belastbarkeit verfügen, da jedoch lediglich an einer Haltevorrichtung die Belagbohlen befestigt werden und somit lediglich diese Haltevorrichtung hohen Belastungen ausgesetzt ist, sind die übrigen Haltevorrichtungen, die lediglich das Geländer befestigen, überdimensioniert. Hierdurch sind die Kosten unnötig erhöht.The holding devices are mounted in known scaffolding tubes at regular intervals on the scaffolding elements. As a rule, four holding devices are attached to scaffolding tubes with a length of two meters. The holding devices fulfill the tasks imposed on them in terms of stability and safety of the attachment of bars and struts. However, a major problem in the construction of a complete scaffold is that after arranging the floor coverings of the additional projectile between the scaffold tubes no hedging of the scaffolder is present by a railing. The railings are made in scaffolding tubes of the type considered here by horizontal struts, which are attached to the holding devices of adjacent tubes. Since the attachment of the railing forming struts can only be done by the scaffolder brings the ends of the respective struts to the holders and fixed by tightening the clamping wedges, the scaffolder is forced to move from a scaffolding tube to the adjacent scaffolding tube before a railing firmly anchored. As a result, in the construction phase of the scaffold on the uppermost floor actually no hedging available, so the risk of accidents is increased. The professional associations therefore demand that a paving of the decking planks may only take place if a railing is already mounted. This is theoretically only to be ensured by the fact that the scaffolder attaching already from the stairs leading to the upper floor of a hinge forming the hinge to the scaffolding tube arranged away from it can, so can make a secure attachment over a span of about 2.5 meters. This is not guaranteed with the known scaffold tubes, in which the attachment to the known disk-shaped holding devices takes place. In addition, the known scaffold stands are provided with four holding devices, which indeed have a high load capacity, however, since only on a holding device, the planks are fixed and thus only this fixture is exposed to high loads, the remaining fixtures that attach only the railing, oversized , As a result, the costs are unnecessarily increased.

Hier will die Erfindung Abhilfe schaffen. Der Erfindung liegt die Aufgabe zu Grunde, einen Gerüstständer für Systemgerüste zu schaffen, der einerseits eine Befestigung der das Geländer bildenden Bauteile aus einer gesicherten Position heraus ermöglicht und andererseits eine in Abhängigkeit der auftretenden Belastungen gewählte Befestigung von Riegeln und Streben ermöglicht. Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, dass genau eine Haltevorrichtung vorgesehen ist, zu der beabstandet mindestens eine Befestigungseinrichtung angeordnet ist.The invention aims to remedy this situation. The invention is based on the object to provide a scaffold stand for system scaffolding, on the one hand allows attachment of the railing forming components from a secured position and on the other hand allows selected depending on the loads occurring fastening of bars and struts. According to the invention, this object is achieved in that exactly one holding device is provided, to which at least one fastening device is arranged at a distance.

Mit der Erfindung ist ein Gerüstständer für Systemgerüste geschaffen, der zur Befestigung der Belagbohlen eine Haltevorrichtung aufweist die eine hohe Belastbarkeit ermöglicht und gleichzeitig die übrigen Befestigungspunkte durch weniger stark belastbare Befestigungseinrichtungen bereitstellt, so dass eine bedarfsgerechte Abstimmung der Befestigungspunkte geschaffen ist. Da die Befestigungseinrichtungen sowohl hinsichtlich ihrer Anbringung an dem Gerüstständer als auch ihrer Dimensionierung geringere Anforderungen stellen, sind die Kosten für die Herstellung des Gerüstständers reduziert.With the invention, a scaffold stand for system scaffolding is created, which has a holding device for fixing the planks which allows high load capacity and at the same time provides the remaining attachment points by less strong fastening devices, so that an appropriate adjustment of the attachment points is created. Since the fastening devices make lower demands both in terms of their attachment to the scaffold stand and their dimensions, the cost of manufacturing the scaffold stand is reduced.

In Weiterbildung der Erfindung sind drei Befestigungseinrichtungen angeordnet. Durch die Anordnung von drei Befestigungseinrichtungen ist eine gleiche Anzahl von Befestigungspunkten an dem, Gerüstständer geschaffen, wie dies bei den bisher bekannten Gerüstständern für Systemgerüste, bei denen die Befestigungspunkte vollständig durch scheibenförmige Haltevorrichtungen gebildet sind, der Fall ist. In Folge dessen ist der erfindungsgemäße Gerüstständer vollständig kompatibel zu den Gerüstständern nach dem Stand der Technik.In development of the invention, three fastening devices are arranged. Due to the arrangement of three fasteners an equal number of attachment points on the scaffold stand is created, as in the previously known scaffold stands for system scaffolding, in which the attachment points are completely formed by disc-shaped holding devices, is the case. As a result, the scaffold stand according to the invention is fully compatible with the scaffold stands according to the prior art.

In Ausgestaltung der Erfindung sind die Befestigungseinrichtungen als Kippstifte ausgebildet. Die Befestigung von Streben und Riegeln mit Hilfe von Kippstiften ist aus dem Stand der Technik bekannt. Die Verwendung der Kippstifte bietet eine zuverlässige Möglichkeit, Geländer an den Gerüstständern anzuordnen, da die Kippstifte über eine selbsttätige Verriegelung verfügen.In an embodiment of the invention, the fastening devices are designed as tilting pins. The attachment of struts and bars with the aid of tilting pins is known from the prior art. The use of the tilting pins provides a reliable way of arranging railings on the scaffolding uprights, since the tilting pins have an automatic locking mechanism.

In vorteilhafter Weiterbildung der Erfindung sind die Befestigungseinrichtungen als Aufnahmebügel ausgebildet, die auf ihrer dem Boden abgewandten Seite, eine Öffnung aufweisen. Die Verwendung der Aufnahmebügel bietet bei der Befestigung der Riegel oder Streben aus der gesicherten Position heraus die Möglichkeit, diese in einfacher Weise auf dem Bügel einzufädeln. Nach dem Einfädeln ist die Strebe bzw. der Riegel zuverlässig in dem Bügel angeordnet, so dass Geländer aus der gesicherten Position heraus in einfacher und zu-verlässiger Weise montierbar und demontierbar sind.In an advantageous embodiment of the invention, the fastening means are designed as receiving bracket, which have on their side facing away from the bottom, an opening. The use of the receiving bracket provides in the attachment of the bars or struts from the secured position out the ability to thread them in a simple manner on the bracket. After threading the strut or the latch is reliably arranged in the bracket, so that railing from the secured position out in a simple and reliable manner are mounted and dismounted.

Bevorzugt hat der Aufnahmebügel auf seiner dem Boden zugewandten Seite eine keilförmige Ausbildung. Die keilförmige Ausbildung des Bügels bewirkt, dass die Strebe bzw. der Riegel nach dem Einfädeln auf den Bügel selbstständig in den gebildeten Keil hineinrutscht, so dass eine Fixierung auf der dem Boden zugewandten Seite erfolgt, was eine spielfreie Positionierung der Strebe bzw. des Riegels ermöglicht.Preferably, the receiving bracket on its side facing the ground has a wedge-shaped design. The wedge-shaped design of the bracket causes the strut or the latch to slip into the formed wedge automatically after threading onto the bracket, so that a fixation takes place on the side facing the floor, which enables a play-free positioning of the strut or the bolt ,

  • Fig. 3 the representation of a recording bracket.

Der als Ausführungsbeispiel gewählte Gerüstständer für Systemgerüste zum Einrüsten von Bauwerken besteht aus einem Rohr 1, das etwa in seiner Mitte eine scheibenförmige Haltevorrichtung 2 aufweist. An dem Rohr sind zudem drei Befestigungseinrichtungen 3 angeordnet, die in gleichmäßigem Abstand über das Rohr 1 verteilt sind. Im Ausführungsbeispiel sind die Haltevorrichtung 2 sowie die Befestigungseinrichtungen 3 jeweils im Abstand von ca. 50 cm zueinander angeordnet. An seinem dem Boden abgewandten Ende ist das Rohr 1 mit einem Zapfen 4 versehen, der zum Aufstecken eines weiteren Rohres dient, um mehretagige Gerüste erstellen zu können.The framework stand chosen as an exemplary embodiment for system scaffolds for the installation of structures consists of a tube 1, which has a disc-shaped holding device 2 approximately in its center. On the tube also three fastening means 3 are arranged, which are distributed over the tube 1 at a uniform distance. In the exemplary embodiment, the holding device 2 and the fastening means 3 are each arranged at a distance of about 50 cm from each other. At its end facing away from the bottom of the tube 1 is provided with a pin 4, which serves for attaching another tube to create multi-layered scaffolding can.

Die Haltevorrichtung 2 ist in bekannter Weise mit Durchbrüchen 21 und 22 versehen. Die Durchbrüche 21 sind länglich und radial zum Querschnitt des Gerüstständers in jeweils zueinander rechtwinkligen Richtungen angeordnet. Zwischen zwei länglichen Durchbrüchen 21 ist jeweils ein weiterer Durchbruch 22 angeordnet, dessen Abmessungen in radialer Richtung gleich der Abmessung der länglichen Durchbrüche ist.The holding device 2 is provided in a known manner with openings 21 and 22. The openings 21 are elongated and arranged radially to the cross section of the scaffold stand in mutually perpendicular directions. Between two elongate openings 21, a further opening 22 is arranged in each case, whose dimensions in the radial direction is equal to the dimension of the elongated openings.

Die Befestigungseinrichtung 3 kann von Kippstiften 5, wie sie in Figur 2 dargestellt sind, oder von Aufnahmebügeln 6, wie sie in Figur 3 dargestellt sind, gebildet sein. Die Befestigungseinrichtung 3 dient zur Anordnung von Rückengeländern, die dann einerseits die Stabilität des Gerüstes erhöhen und andererseits eine Absturzsicherung darstellen. Die am kopfseitigen Ende des Rohres 1 vorgesehenen Befestigungseinrichtung 3 bietet die Möglichkeit zur Befestigung einer Diagonalverstrebung.The fastening device 3 can by tilting pins 5, as shown in FIG. 2 are shown, or of receiving hoops 6, as in FIG. 3 are shown formed. The fastening device 3 is used for the arrangement of back railings, which then increase the stability of the scaffold on the one hand and on the other hand represent a fall protection. The provided at the head end of the tube 1 fastening device 3 offers the possibility for attachment of a diagonal bracing.

Die Kippstifte 5 bestehen aus einer rechtwinklig zum Rohr 1 ausgerichteten Basis 51. Die Basis 51 hat einen zylindrischen Querschnitt. An seinem dem Rohr 1 abgewandten Ende ist ein Schlitz vorgesehen. Die an dem Schlitz angrenzenden Zylinderabschnitte 52 sind von jeweils einer Bohrung durchsetzt, in der ein Bozen 53 angeordnet ist. Auf dem Bolzen 53 ist drehbar ein Kippelement 54 angeordnet, welches an seinem einen Ende spitz ausgebildet ist. Da die Bohrung zum Durchtritt des Bozens 53 in dem der Spitze abgewandten Drittel des Kippelements 54 angeordnet ist, ist auf Grund dieser Asymmetrie gewährleistet, dass das Kippelement 54 immer in eine vertikale Position fällt.The tilting pins 5 consist of a base 51 oriented at right angles to the tube 1. The base 51 has a cylindrical cross-section. At its end facing away from the tube 1, a slot is provided. The adjacent to the slot cylinder portions 52 are penetrated by a respective bore in which a Bolzano 53 is arranged. On the bolt 53, a tilting element 54 is rotatably arranged, which is formed pointed at one end. Since the bore for the passage of the bolt 53 is arranged in the third of the tilting element 54 facing away from the tip, this asymmetry ensures that the tilting element 54 always falls into a vertical position.

Die in Figur 3 dargestellte Befestigungseinrichtung in Form eines Aufnahmebügels 6 ist aus einem Stift 61 hergestellt, der unter einem spitzen Winkel an das Rohr 1 angeschweißt ist. Der Aufnahmebügel 6 hat daher auf seiner dem Boden zugewandten Seite eine keilförmige Ausbildung. Auf seiner dem Boden abgewandten Seite ist eine Öffnung 62 ausgebildet, die sich aus dem Abstand des freien Endes des Stiftes 61 zum Rohr 1 ergibt. Benachbart zu der Öffnung 62 ist der Stift 61 angenähert rechtwinklig umgebogen, so dass sich ein im wesentlichen vertikaler Abschnitt 63 ergibt, der auf dem Boden zugewandten Ende in Richtung des Rohres 1 einschwenkt, woraus sich die keilförmige Ausbildung ergibt.In the FIG. 3 fastening device shown in the form of a receiving bracket 6 is made of a pin 61 which is welded at an acute angle to the tube 1. The receiving bracket 6 therefore has a wedge-shaped design on its side facing the floor. On its side facing away from the bottom, an opening 62 is formed, which results from the distance of the free end of the pin 61 to the tube 1. Adjacent to the opening 62 of the pin 61 is bent approximately at right angles, so that there is a substantially vertical portion 63, which pivots on the ground-facing end in the direction of the tube 1, resulting in the wedge-shaped configuration.

Der erfindungsgemäße Gerüstständer weist lediglich eine aus dem Stand der Technik bereits bekannte Haltevorrichtung 2 auf. Da die übrigen Befestigungspunkte für Streben und Geländer durch einfache Befestigungseinrichtungen 3 bereitgestellt sind, kann auf zusätzliche geschmiedete Haltevorrichtungen 2 verzichtet werden, wodurch die Herstellungskosten erheblich gesenkt sind. Die Befestigungseinrichtungen 3 ermöglichen zudem eine Montage der das Geländer bildenden Streben aus einer gesicherten Position heraus. Dies ist dadurch gewährleistet, dass die Streben von der gesicherten Position heraus auf die Befestigungseinrichtungen 3 aufgefädelt werden können. Bei Verwendung eines Kippstiftes 5 erfolgt dies dadurch, dass die Strebe mit ihrer an dem Ende vorgesehenen Öffnung an das Kippelement 54 herangeführt wird und von dort auf die Basis 51 aufgelegt wird. Durch das dann automatisch in seine vertikale Position fallenden Kippelement 54 ist die aufgefädelte Strebe gegen selbstständiges Herabfallen gesichert.The scaffold stand according to the invention has only one holding device 2 already known from the prior art. Since the remaining attachment points for struts and railings are provided by simple fasteners 3, can be dispensed with additional forged holding devices 2, whereby the manufacturing cost is significantly reduced. The fasteners 3 also allow mounting of the railing forming struts from a secured position out. This is ensured by the fact that the struts can be threaded onto the fastening devices 3 from the secured position. When using a tilting pin 5, this is done by the strut with its at the end provided opening is brought to the tilting element 54 and is placed on the base 51 from there. By then automatically falling into its vertical position tilting element 54, the threaded strut against independent fall is secured.

Bei Verwendung eines Aufnahmebügels 6 erfolgt die Montage einer das Geländer bildenden Strebe aus der gesicherten Position ebenfalls durch einfädeln. Hierbei muss lediglich die an dem freien Ende der Strebe vorgesehene Öffnung in die Öffnung 62 eingeführt werden und auf den Stift 61 aufgefädelt werden. Auf Grund der Ausbildung des Aufnahmebügels 6 bewegt sich die Strebe dann automatisch in die keilförmige Ausbildung auf der dem Boden zugewandten Seite des Aufnahmebügels 6, in der die Strebe dann spielfrei gehalten ist.When using a receiving bracket 6, the assembly of a railing forming the strut from the secured position is also threaded through. In this case, only the provided at the free end of the strut opening must be inserted into the opening 62 and threaded onto the pin 61. Due to the design of the receiving bracket 6, the strut then moves automatically into the wedge-shaped training on the ground-facing side of the receiving bracket 6, in which the strut is then held without play.
