Description

Die vorliegende Erfindung betrifft einen Fachwerkträger zum Aufbau von Bühnen, Gerüsten od. dgl., mit mindestens zwei in Trägerlängsrichtung verlaufenden Gurten, die von Fachwerkstreben in gegenseitigem Abstand gehalten sind, wobei zumindest zwei der Fachwerkstreben einander in einem Kreuzungspunkt kreuzen.The present invention relates to a truss for the construction of stages, scaffolding od. Like., With at least two in the longitudinal direction straps extending from truss struts are kept at a mutual distance, at least two of the truss struts cross each other at a crossing point.

Bühnen, Gerüste od. dgl. unterliegen strengen Sicherheitsbestimmungen zur Vermeidung von Personengefährdungen. Es wird erwartet, daß zukünftige Vorschriften eine eindeutige Produktkennzeichnung aller bei solchen Konstruktionen verwendeten Bauteile, wie Fachwerkträger, vorschreiben, um im Bedarfsfall jederzeit den Hersteller und die Charge zurückverfolgen zu können.Stages, scaffolding or the like are subject to strict safety regulations to avoid personal injury. It will Expects future regulations to have a clear product label all components used in such constructions, As trusses, prescribe to order if needed at any time traceable to the manufacturer and the batch.

Die Erfindung setzt sich daher zum Ziel, einen Fachwerkträger zu schaffen, welcher die Möglichkeit zu einer deutlich sichtbaren, dabei aber dauerhaften und zuverlässigen Kennzeichnung bietet. Dieses Ziel wird bei einem Fachwerkträger der einleitend genannten Art erfindungsgemäß dadurch erreicht, daß die Fachwerkstreben in ihrem Kreuzungspunkt über eine Nabe miteinander verbunden sind, welche auf zumindest einer ihrer von Fachwerkstreben freien Seiten einen im wesentlichen ebenen Bereich zur Aufnahme einer Kennzeichnung aufweist, der von einem über die Ebene des Bereiches vorspringenden Wulst umgeben ist.The invention therefore sets itself the goal of a truss to create, which the possibility to a clear visible, but durable and reliable labeling offers. This goal will be initiated by a truss operator mentioned type according to the invention achieved in that the Truss struts in their crossing point over a hub with each other connected to at least one of their Truss struts free sides a substantially flat area for receiving a label from a surrounded by the plane of the area protruding bead.

Auf diese Weise wird eine Kennzeichnungsfläche geschaffen, welche durch den vorspringenden Wulst gegenüber Beschädigungen geschützt ist, wie sie beispielsweise von Hammerschlägen beim Gerüstauf- oder -abbau hervorgerufen werden könnten. Die Erfindung beruht dabei auf der Erkenntnis, daß die Anordnung des Kennzeichnungsbereiches auf einer Nabe in dem genannten Kreuzungspunkt in keiner Weise die strukturelle Integrität des Fachwerkträgers beeinträchtigt und dennoch keinen zusätzlichen, am Fachwerkträger anzubringenden Teil, z.B. ein Kennzeichnungsschild, erfordert.In this way a marking area is created which by the projecting bead against damage is protected, as for example by hammer blows Scaffolding or dismantling could be caused. The invention is based on the knowledge that the arrangement of the Identification area on a hub in said crossing point in no way the structural integrity of the Trusses affected and yet no additional, to be attached to the truss, e.g. a label, requires.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist die Nabe im wesentlichen zylindrisch, wobei der genannte Bereich durch eine zentrale Vertiefung in einer ihrer Stirnseiten und der Wulst durch den verbleibenden, umlaufenden Rand der Stirnseite gebildet ist. Dadurch kann der Kennzeichnungsbereich einfach durch maschinelles Abarbeiten eines Zylinderrohlings ausreichender Höhe gefertigt werden. Dies beruht auf der Erkenntnis der Anmelderin, daß genau dieser Bereich des Fachwerkträgers der einzige Bereich ist, welcher gefahrlos maschinell abgearbeitet (z.B. gefräst) werden kann, ohne die strukturelle Integrität bzw. mechanische Festigkeit des Fachwerkträgers zu gefährden.According to a preferred embodiment of the invention the hub is substantially cylindrical, said area through a central depression in one of its faces and the bead through the remaining, circumferential edge of the Front side is formed. This allows the tagging area simply by machining a cylinder blank sufficient height to be made. This is based on the knowledge the applicant that exactly this area of trusses the only area is which machine safely can be processed (for example, milled) without the structural Integrity or mechanical strength of the truss bearer compromise.

Bevorzugt trägt der genannte Bereich als Kennzeichnung eine Gravur oder Prägung. Diese Art der Kennzeichnung ist besonders dauerhaft.Preferably, the said area bears as a marking Engraving or embossing. This type of identification is special permanently.

Eine weitere vorteilhafte Ausführungsform der Erfindung zeichnet sich dadurch aus, daß der Fachwerkträger aus Aluminium gefertigt und die Fachwerkstreben an die Nabe angeschweißt sind. Dies ergibt geringes Gewicht bei gleichzeitig hoher Festigkeit.A further advantageous embodiment of the invention is characterized in that the truss girder made of aluminum manufactured and welded the truss struts to the hub are. This results in low weight and high strength.

Besonders günstig ist es, wenn bei Fachwerkträgern mit vier Gurten, wobei die kreuzenden Fachwerkstreben diametral gegenüberliegende Gurten verbinden, die Nabe vier Fachwerkstreben verbindet, die in einem Winkelabstand von 90° an der Nabe ansetzen. Dies ergibt eine symmetrische Lastverteilung an der Nabe. In gleicher Weise ist es alternativ für Fachwerkträger mit drei Gurten besonders günstig, wenn die Nabe drei Fachwerkstreben verbindet, die in einem Winkelabstand von 120° an der Nabe ansetzen.It is particularly favorable when with trusses with four straps, with the crossing truss struts diametrically opposed Connecting straps, the hub four truss braces connecting at an angular distance of 90 ° to the hub. This results in a symmetrical load distribution at the hub. In the same way it is alternatively for trusses with three straps particularly favorable, if the hub three truss struts connects at an angular distance of 120 ° to the hub begin.

Die Erfindung wird nachstehend anhand von in den Zeichnungen dargestellten Ausführungsbeispielen näher erläutert. In den Zeichnungen zeigt Fig. 1 einen erfindungsgemäßen Fachwerkträger mit vier Gurten ausschnittsweise in einer Perspektivansicht in Richtung auf seine Stirnseite, Fig. 2 die Nabe des Fachwerkträgers von Fig. 1 im Axialschnitt, Fig. 3 die Nabe mit den kreuzenden Fachwerkstreben von Fig. 1 in der Draufsicht, und die Fig. 4 und 5 eine Nabe mit angeschlossenen Fachwerkträgern zweier alternativer Ausführungsformen von Fachwerkträgern.The invention will be described below with reference to the drawings illustrated embodiments explained in more detail. In the Drawings, Fig. 1 shows a truss girder according to the invention with four straps fragmentary in a perspective view in Direction to its front page, Fig. 2, the hub of the truss girder of Fig. 1 in axial section, Fig. 3, the hub with the intersecting Truss struts of Fig. 1 in plan view, and the 4 and 5 a hub with attached truss girders two alternative embodiments of truss girders.

Gemäß den Fig. 1 bis 3 ist ein Fachwerkträger 1 aus in Trägerlängsrichtung verlaufenden Gurten 2-5 aufgebaut, und zwar zwei Obergurten 2, 3 und zwei Untergurten 4, 5, welche über Fachwerkstreben 6, 7 in gegenseitigem Abstand gehalten sind.According to FIGS. 1 to 3, a truss girder 1 is made of Carrier longitudinally extending straps 2-5 constructed, namely two upper straps 2, 3 and two lower straps 4, 5, which over Truss braces 6, 7 are held at a mutual distance.

Wie in Fig. 1 dargestellt, gibt es im wesentlichen zwei Arten von Fachwerkstreben 6, 7, und zwar einmal Fachwerkstreben 6, welche schräg zwischen benachbarten Gurten 2, 3; 3, 4; 4, 5; bzw. 5, 2 verlaufen, und zweite Fachwerkstreben 7, welche diametral gegenüberliegende Gurte 2, 4; 3, 5 miteinander verbinden. Letztere Fachwerkstreben 7 kreuzen sich in einem Kreuzungspunkt 8 und sind dort über eine Nabe 9 miteinander verbunden. Mit anderen Worten sind die sich kreuzenden Fachwerkstreben 7 jeweils zweiteilig ausgeführt und die Nabe 9 ist zwischengeschaltet, so daß die beiden Teile diametral an der Nabe 9 ansetzen.As shown in Fig. 1, there are substantially two Types of truss struts 6, 7, and once truss struts 6, which obliquely between adjacent straps 2, 3; 3, 4; 4, 5; or 5, 2 run, and second truss struts 7, which diametrically opposite straps 2, 4; 3, 5 connect together. The latter truss braces 7 intersect at a crossing point 8 and are connected there via a hub 9. In other words, the intersecting truss struts 7 each made in two parts and the hub 9 is interposed, so that the two parts are diametrically on the hub 9 start.

Gemäß Fig. 2 ist die Nabe 9 im wesentlichen zylindrisch und weist auf ihren von Fachwerkstreben freien Seiten, d.h. ihren Stirnseiten, jeweils einen ebenen Bereich 10, 11 zur Aufnahme einer Kennzeichnung 12 auf. Die Kennzeichnung 12 ist bevorzugt eine Gravur oder Prägung des Bereiches 10, kann aber alternativ auch durch eine Farbmarkierung, einen Aufkleber usw. erzeugt werden. Auch der Bereich 11 kann mit einer derartigen Kennzeichnung 12 versehen sein (nicht dargestellt).According to Fig. 2, the hub 9 is substantially cylindrical and indicates its truncation-strut-free sides, i. their End faces, each having a planar portion 10, 11 for receiving a label 12. The label 12 is preferred an engraving or embossing of the area 10, but can Alternatively, by a color marker, a sticker, etc. be generated. Also, the area 11 can with such Label 12 be provided (not shown).

Die Bereiche 10, 11 sind jeweils von einem über die Ebene des Bereiches vorspringenden Wulst 13, 14 umgeben. Der Wulst 13, 14 dient zum Schutz des Bereiches 10 bzw. 11 vor Beschädigung, beispielsweise wenn beim Zusammenbau oder der Zerlegung aneinander anschließender Fachwerkträger 1 Bolzen (nicht dargestellt) mittels Hammerschlägen durch Bohrungen 15 der Fachwerkträger 1 getrieben werden.The areas 10, 11 are each one above the level surrounded by the region projecting bead 13, 14. The bead 13, 14 serves to protect the area 10 or 11 from damage, for example, when assembling or disassembling adjoining truss girder 1 bolt (not shown) by means of hammer blows through holes 15 of the truss girder 1 to be driven.

Die Höhe des bzw. der Wulste 13, 14 wird dabei im Verhältnis zur Größe der Bereiche 10, 11 so gewählt, daß ein ausreichender Schlagschutz der Markierung 12 bei flachwinkelig über der Nabe 9 ausgeführten Schlägen gewährleistet ist, gleichzeitig aber eine gute Sichtbarkeit der Kennzeichnung 12 erhalten bleibt. In einer beispielhaften Ausführungsform, in welcher der Durchmesser der Nabe 3 bis 5 cm ist, beträgt die Höhe der Wulste 2 bis 10 mm und ihre Breite (Radius der Nabe 9 minus Radius des Bereiches 10, 11) 2 bis 10 mm.The height of the bead or beads 13, 14 is in proportion to the size of the areas 10, 11 chosen so that a sufficient Impact protection of marking 12 at a flat angle the hub is ensured 9 executed strokes, at the same time but get a good 12-mark visibility remains. In an exemplary embodiment in which the Diameter of the hub is 3 to 5 cm, the height of the beads is 2 to 10 mm and their width (radius of the hub 9 minus radius of the area 10, 11) 2 to 10 mm.

Die Bereiche 10, 11 und die Wulste 13, 14 können in einem Schritt gefertigt werden, bevorzugt durch maschinelles Abarbeiten, z.B. Drehen oder Fräsen, der Stirnseiten eines Zylinderrohlings der Nabe, wodurch der Wulst als umlaufender, nichtabgearbeiteter Rand verbleibt.The areas 10, 11 and the beads 13, 14 can in a Step are made, preferably by machine processing, e.g. Turning or milling, the front sides of a cylinder blank the hub, causing the bead as circumferential, not worked Edge remains.

Der Fachwerkträger 1 ist bevorzugt aus Aluminium gefertigt. Das Anschließen der Teile der Fachwerkstreben 7 an die Nabe 9 kann in diesem Fall durch Verschweißen erfolgen, bevorzugt durch Wolfram-Inertgas-Schweißen (WIG-Schweißen).The truss girder 1 is preferably made of aluminum. Connecting the parts of the truss braces 7 to the Hub 9 can be made in this case by welding, preferably by tungsten inert gas welding (TIG welding).

Die Fig. 4 und 5 zeigen zwei weitere Ausführungsformen von mit Naben 9 versehenen Kreuzungspunkten 8 zwischen Fachwerkstreben 7 von Fachwerkträgern mit drei Gurten (Fig. 4) bzw. nur Obergurt und Untergurt (Fig. 5) (Gurte nicht dargestellt). Es ist ersichtlich, daß unter dem Begriff "Kreuzungspunkt" 8 von sich kreuzenden Fachwerkträgern 7 auch solche Verbindungspunkte von Fachwerkträgern 7 verstanden werden, wie sie in den Fig. 4 und 5 dargestellt sind.Figs. 4 and 5 show two further embodiments of provided with hubs 9 crossing points 8 between truss braces 7 truss trusses with three straps (Fig. 4) or only Upper belt and lower belt (Fig. 5) (straps not shown). It It can be seen that the term "crossing point" 8 of intersecting trusses 7 also such connection points Truss beams 7 are understood, as shown in FIGS. 4 and FIG. 5 are shown.

Die Erfindung ist selbstverständlich nicht auf die dargestellten Ausführungsformen beschränkt, sondern umfaßt alle Varianten und Modifikationen, die in den Rahmen der angeschlossenen Ansprüche fallen. Insbesondere ist die Form, Fachwerk-Verstrebungsart, Größe, Materialwahl usw. des Fachwerkträgers beliebig variierbar. Auch die Querschnittsform und die Umfangskontur der Wulste 13, 14 ist beliebig, solange sie einen ausreichenden Schutz für die Bereiche 10, 11 bieten. Die Bereiche 10, 11 müssen nicht notwendigerweise eben sein wie dargestellt, sondern können auch strukturiert, gekrümmt usw. sein, solange sie von den Wulsten 13, 14 ausreichend geschützt werden können. Die Nabe 9 braucht nur auf einer Seite mit einem Bereich 10, einer Kennzeichnung 12 und einem Wulst 13 ausgestattet zu sein. Die Umfangsform der Nabe 9 muß nicht notwendigerweise zylindrisch sein, auch polygonale Formen oder unregelmäßig gekrümmte oder abgeflachte Formen sind denkbar, z.B. Würfelform usw.The invention is of course not on the illustrated Embodiments limited, but includes all variants and modifications included in the framework of the Claims fall. In particular, the shape, truss bracing, Size, choice of material etc. of the truss bearer freely variable. Also the cross-sectional shape and the peripheral contour The beads 13, 14 is arbitrary, as long as they have a sufficient Provide protection for the areas 10, 11. The areas 10, 11 do not necessarily have to be as shown but can also be structured, curved, etc., as long as they can be sufficiently protected by the beads 13, 14. The hub 9 needs only on one side with an area 10, a label 12 and a bead 13 to be equipped. The peripheral shape of the hub 9 does not necessarily have to be cylindrical be, even polygonal shapes or irregularly curved or flattened shapes are conceivable, e.g. Cube shape, etc.
