Description

Die Erfindung bezieht sich auf ein Gerüstelement mit in einem Abstand voneinander parallel angeordneten sowie durch querverlaufende Rohrstreben verbundenen Rohren, dessen Rohrstreben mit Haltevorrichtungen zur Befesti­gung oder Festlegung von Bohlen, Planken oder anderen Ergänzungselementen ausgerüstet sind. Die Rohre sind überlicherweise jeweils an ihren einen Enden mit Steck­bolzen zum Zusammenstecken mit weiteren Gerüstelementen versehen, ihre rohrstreben nahe den Rohrenden ange­bracht.The invention relates to a scaffold element with parallel spaced tubes and connected by transverse tube struts, the tube struts are equipped with holding devices for fastening or fixing planks, planks or other supplementary elements. The tubes are usually provided at one end with plug-in bolts for plugging together with other scaffolding elements, their tube struts attached near the tube ends.

Mit Hilfe derartiger Gerüstelementen können beispiels­weise Baugerüste für mehrere Etagen übereinander und für größere Forntängen durch einfaches Zusammenstecken und Miteinanderverbinden dieser Einzelelemente aufgebaut werden. Dabei sind Hilfs- bzw. Haltevorrichtungen vorge­sehene, um außer den Bohlen bzw. Planken zum Begehen der einzelnen Gerüst-Etagen auch Geländer und andere Schutz­vorrichtungen anzubringen.With the help of such scaffolding elements, for example, scaffolding for several levels can be built one above the other and for larger form lengths by simply plugging these individual elements together and connecting them together. Auxiliary or holding devices are provided in order to attach railings and other protective devices in addition to the planks or planks for accessing the individual scaffolding levels.

Zum Befestigen der Bohlen bzw. Planken sind an den quer­verlaufenden Rohrstreben -- runden oder eckigen Quer­schnitts --, vorzugsweise jedoch nur an der jeweils oberen querverlaufenden Rohrstrebe, nach oben gerichtete Haltezapfen verschweißt. Diese greifen beim Auflegen der Bohlen in dort vorhandene vorbereitete Löcher ein, so daß diese Bohlen bzw. Planken sowohl in Längs- wie auch in Querrichtung verschieblich festgelegt sind.To fasten the planks or planks, upwardly directed retaining pins are welded to the transverse pipe struts - round or angular cross-section, but preferably only to the upper transverse pipe strut. These engage when the planks are placed in the prepared holes provided there, so that these planks or planks are displaceably fixed both in the longitudinal and in the transverse direction.

Das Anschweißen der einzelnen Haltezapfen an diese Rohr­streben ist nicht nur arbeitszeitaufwendig und daher kostspielig, es hat auch noch den Nachteil, daß Schweiß- oder Bohrvorrichtungen benutzt werden müssen, um eine genaue und rationelle Arbeitsweise zu ermöglichen. Zudem erfolgt eine Einleitung entstehender Horizontalkräfte über die Schweißnähte, was oftmals zu Abrissen führt.The welding of the individual holding pins to these pipe struts is not only labor-intensive and therefore expensive, it also has the disadvantage that welding or drilling devices have to be used in order to enable an accurate and efficient operation. In addition, horizontal forces are introduced via the weld seams, which often leads to tearing.

Angesichts dieser Gegebenheit hat sich der Erfinder das Ziel gesetzt, die erkannten Mängel zu beseitigen und das eingangs erwähnte Bauelement zu verbessern, das Anbrin­gen dieser Haltezapfen dadurch zu vereinfachen, daß ein geringerer Arbeitszeitaufwand und zugleich eine höhere Genauigkeit erzielt wird, insbesondere auch die Weiter­leitung der Horizontalkräfte güstiger zu gestalten und Abrisse zu vermeiden.In view of this fact, the inventor has set itself the goal of eliminating the identified shortcomings and improving the above-mentioned component, simplifying the attachment of these retaining pins in that less working time and at the same time higher accuracy is achieved, in particular also the transmission of the horizontal forces to make it cheaper and to avoid demolition.

Zur Lösung dieser Aufgabe führt erfindungsgemäß, daß die querverlaufenden Rohrstreben mit wenigstens zwei ein ge­meinsames Formstück bildenden Haltezapfen versehen sind, welches der betreffenden Rohrstrebe wenigstens an ihrer Oberseite und daran anschließend an beiden Seiten passend anliegt und mit ihr -- durch eine Schweißnaht gegebenenfalls unlösbar -- verbunden ist. Das Formstück -- für dessen Gestaltung selbständig Schutz beansprucht wird -- besteht aus den parallelen Haltezapfen und einem querschnittlich rinneartigen Sockelstück, dessen Rinnenöffnung zur Rohrstrebe weist.According to the invention, this problem is solved in that the transverse tube struts are provided with at least two retaining pins forming a common shaped piece, which fits the tube strut in question at least on its upper side and then on both sides and with it - possibly unsolvable by a weld seam - connected is. The shaped piece - for whose design protection is claimed independently - consists of the parallel retaining pin and a cross-sectionally gutter-like base piece, the gutter opening facing the tubular strut.

Die querverlaufende Rohrstrebe kann einen rechteckigen oder runden Querschnitt und das Formstück mit den Halte­zpafen einen entsprechend geformten, die Rohrstrebe eng umschließenden Ausschnitt aufweisen. Vorzugsweise ist das die Rohrstrebe ganz oder teilweise umschließende Formstück mit dieser durch Anschweißen verbunden. Es ist jedoch auch möglich, das die Rohrstrebe ganz oder teil­weise umschließende Formstück mit dieser durch Vernieten oder Verschrauben zu verbinden, im letztgenannten Falle also lösbar zu erhalten.The transverse tube strut can have a rectangular or round cross-section and the shaped piece with the holding pins has a correspondingly shaped cutout which closely surrounds the tube strut. Preferably, the molded part completely or partially surrounding the tubular strut is connected to it by welding. However, it is also possible to connect the shaped part wholly or partially surrounding the tubular strut to this by riveting or screwing, in the latter case to obtain it releasably.

Das erfindungsgemäße Formstück besteht bevorzugt aus stranggepreßten Aluminiumteilen, kann aber auch aus anderem Werkstoff -- etwa Stahl -- hergestellt sein.The shaped part according to the invention preferably consists of extruded aluminum parts, but can also be made of another material, such as steel.

Weitere Merkmale der Erfindung bestehen noch darin, daß die Haltezapfen des Formstückes -- zumindest teilweise -- von rundem Querschnitt sind und einen Durchmesser zwischen 15 und 20 mm sowie eine freie Länge zwischen 30 und 60 mm aufweisen, und ferner, daß die Haltezapfen beidseitig der Rohrstrebe in einem Abstand zwischen 30 und 60 mm voneinander angeordnet sind. Die Haltezapfen sind also beidseitig der Rohrstrebe paarweise angebracht, und jeder der Haltezapfen greift in eines der Löcher jeder aufeinander folgend benachbarten Bohle ein. Dabei liegen die Bohlen auf einem Steg des Formstückes und über diesen der querverlaufenden Rohr­strebe auf.Further features of the invention consist in the fact that the retaining pins of the shaped piece are - at least partially - of round cross-section and have a diameter between 15 and 20 mm and a free length between 30 and 60 mm, and further that the retaining pins on both sides of the Pipe brace are arranged at a distance between 30 and 60 mm from each other. The retaining pins are therefore attached in pairs on both sides of the tubular strut, and each of the retaining pins engages in one of the holes in each successively adjacent screed. The planks lie on a web of the shaped piece and over this the transverse tube strut.

Vorteilhafterweise sind auf einer Rohrstrebe vier mit einem einzigen oder zwei getrennten Formstücken verbun­dene Haltezapfen befestigt. Besonders zweckmäßig ist es, wenn auf einer Rohrstrebe acht Haltezapfen angeordnet sind, von denen wahlweise jeweils zwei oder vier mit einem Formstück verbunden sind. Es hat sich ferner auch als günstig erwiesen, jeweils zwei Haltezapfenpaare in einem Abstand von ca. 220 bis 280 mm voneinander ent­fernt auf einer Rohrstrebe anzubringen und den Abstand zwischen im Mittenbereich benachbarten Haltezapfenpaaren mit etwa 40 bis 80 mm zu wählen.Advantageously, four holding pins connected to a single or two separate shaped pieces are fastened to a tubular strut. It is particularly expedient if eight holding pins are arranged on a tubular strut, two or four of which are optionally connected to a shaped piece. It has also proven to be advantageous to attach two pairs of retaining pins at a distance of approximately 220 to 280 mm from one another on a tubular strut and to select the distance between adjacent pairs of retaining pins in the central region at approximately 40 to 80 mm.

Dank der beschriebenen erfindungsgemäßen Ausgestaltung wirken die -- beispielsweise auch durch Windkräfte be­einflußten -- eingeleiteten Horizontalkräfte nicht mehr auf seitliche Schweißnähte. Soweit Schweißnähte beim Er­findungsgegenstand auftreten, dienen sie lediglich der Fixierung der Teile; die Kräfte werden über die zusammenhängende und formschlüssige Einheit Formstück/­Rohrstrebe unmittelbar in die nächstliegende Bohlenebene bzw. in den Querschnitt der querverlaufenden Rohrstrebe eingeleitet.Thanks to the configuration according to the invention described, the horizontal forces introduced - for example also influenced by wind forces - no longer act on lateral weld seams. As far as weld seams occur in the subject matter of the invention, they only serve to fix the parts; the forces are introduced directly into the nearest screed plane or into the cross-section of the transverse pipe strut via the coherent and form-fitting unit shaped part / pipe strut.

Wie aus Fig. 1 ersichtlich ist, sind zwei Gerüstelemente 1 mittels angedeuteter Fußelemente 8 aufgestellt. Die Gerüstelemente 1 bestehen jeweils aus in einem Abstand parallellaufenden Rohren 2, die an ihren Endbereichen mittels zweier querverlaufender Rohrstreben 3 miteinander verbunden sind. Zudem sind an den oberen Enden der Rohre Steckbolzen 9 zum Zusammenstecken mit weiteren Gerüstelementen oder sonstigen Ergänzungsteilen vorgesehen. Zwischen den beiden Gerüstelementen 1 verlaufen Diagonalstreben 13.As can be seen from FIG. 1, two scaffolding elements 1 are set up by means of indicated foot elements 8. The scaffolding elements 1 each consist of tubes 2 running in parallel at a distance, which are connected to one another at their end regions by means of two transverse tube struts 3. In addition, plug pins 9 are provided on the upper ends of the tubes for plugging together with other scaffolding elements or other supplementary parts. Diagonal struts 13 run between the two scaffolding elements 1.

Die obere querverlaufende Rohrstrebe 3 ist mit Halte­zapfen 5 versehen, die beim Auflegen von Bohlen 10 auf die Rohrstrebe 3 in dort vorbereitete -- aus Gründen der Uebersichtlichkeit in der Zeichnung nicht erkennbare -- Löcher eingreifen, so daß die Bohlen 10 sowohl in Quer- wie in Längsrichtung festgelegt sind.The upper transverse pipe strut 3 is provided with holding pins 5 which, when placing planks 10 on the pipe strut 3, engage in holes prepared there - for reasons of clarity in the drawing - not recognizable - so that the planks 10 both in transverse and are set in the longitudinal direction.

Weiterhin ist in Fig. 1 noch ein Aufsteckelement 11 dar­gstellt, welches dazu dient, die Bohlen 10 in ihrer Auf­lageposition auf der Rohrstrebe 3 festzuhalten, so daß sie nicht nach oben aus der Festlegung mittels der Haltezapfen 5 herausspringen können. Anstelle von Rohr­stücken 12 zum Befestigen von Seitengeländern kann auch ein weiteres Gerüstelement 1 aufgesteckt werden.Furthermore, a plug-on element 11 is also shown in FIG. 1, which serves to hold the planks 10 in their resting position on the tubular strut 3, so that they cannot jump upwards out of the fixing by means of the holding pins 5. Instead of pipe sections 12 for fastening side railings, a further scaffolding element 1 can also be attached.

In Fig. 2 ist ein Gerüstelement 1 nach der Erfindung im einzelnen dargestellt. Die beiden parallelen Rohre 2 sind unten und oben mittels der querverlaufenden Rohr­streben 3 miteinander verbunden. Im Ausführungsbeispiel ist nur die obere Rohrstrebe 3 mit den Haltezapfen 5 zum Befestigen der Bohlen bzw. Planek 10 versehen.2 shows a scaffold element 1 according to the invention in detail. The two parallel tubes 2 are connected below and above by means of the transverse tube struts 3. In the exemplary embodiment, only the upper tubular strut 3 is provided with the holding pin 5 for fastening the planks or Planek 10.

Ein Formstück 4 mit zwei Haltezapfen 5 und einem quer­schnittlich C-förmigen Sockelstück 7 ist aus Fig. 3 er­sichtlich. Dieses Formstück 4 liegt mit seinem Stockel­stück 7 der Oberseite und den Seiten der Rohrstrebe 3 an, welche hier eien rechteckigen Querschnitt aufweist.A fitting 4 with two holding pins 5 and a cross-sectionally C-shaped base piece 7 can be seen in FIG. 3. This shaped piece 4 lies with its fuselage piece 7 on the top and the sides of the tubular strut 3, which here has a rectangular cross section.

Das Formstück 4 kann drei Seiten der Rohrstrebe 3 ganz umschließen oder -- wie in Fig. 3 verdeutlicht -- an den Seiten nur mit kurzen Schenkeln 30 ausgestattet sein. Wie aus der Darstellung weiterhin hervorgeht, kann das Formstück 4 entweder mit der Rohrstrebe verschweißt sein (rechte Figurenhälfte), oder aber die Befestigung erfolgt mittels einer Verschraubung bzw. Vernietung 14 (linke Figurenhälfte). Der Durchmesser d des Haltezapfens 5 beträgt hier etwa 17 mm bei einer Gesamthöhe des Formstückes 4 von 80 mm und einer Breite e des plattenartigen Steges 31 jenes Sockelstückes 7 von ebenfalls etwa 17 mm.The shaped piece 4 can completely enclose three sides of the tubular strut 3 or - as illustrated in FIG. 3 - can be equipped with only short legs 30 on the sides. As can further be seen from the illustration, the molded piece 4 can either be welded to the tubular strut (right half of the figure), or it can be fastened by means of screwing or riveting 14 (left half of the figure). The diameter d of the holding pin 5 here is approximately 17 mm with a total height of the shaped piece 4 of 80 mm and a width e of the plate-like web 31 of that base piece 7 of likewise approximately 17 mm.

Zum leichteren Einführen der mit den Löchern versehenen Bohlen bzw. Planken ist jeder Haltezapfen 5 mit einem Einführungskonus 6 versehen.For easier insertion of the planks or planks provided with the holes, each holding pin 5 is provided with an insertion cone 6.

Bei einer besonderen Ausführungsform sind an einem Form­stück 4 vier Haltezapfen 5 befestigt, wobei jeweils zwei Haltezapfen in Blickrichtung hintereinander liegen. In diesem Falle sind die vier im Mittenbereich der Rohr­strebe 3 (siehe Fig. 1) vorhandenen vier Haltezapfen 5 in einer Formstück-Einheit zusammengefaßt. Dadurch wird eine noch schnellere Montage ermöglicht.In a special embodiment, four holding pins 5 are fastened to a shaped piece 4, two holding pins each lying one behind the other in the viewing direction. In this case, the four four holding pins 5 present in the central region of the tubular strut 3 (see FIG. 1) are combined in a molding unit. This enables an even faster assembly.
