Description

Die Erfindung betrifft Gitterträger für Gerüste, deren senkrechte Gerüststiele im Rasterabstand horizontale Lochscheiben aufweisen, über welche Anschlußköpfe steckbar sind, die mittels Keilen sicherbar sind, wobei der Gitterträger einen Obergurt, einen Untergurt, Vertikal- und Diagonalstäbe und Anschlußmittel für die Verbindung mit den vertikalen Gerüststielen aufweist.The invention relates to lattice girders for scaffolds, the vertical scaffold posts of which have horizontal perforated disks at a grid spacing, via which connection heads can be plugged in, which can be secured by means of wedges, the lattice girder having an upper chord, a lower chord, vertical and diagonal bars and connecting means for connection to the vertical scaffold posts having.

Zur 4berbrückung größerer Spannweiten, bei denen einfache Horizontal-Tragelemente, wie Rundrohre oder Profilstäbe, nicht ausreichen, verwendet man im Gerüstbau Gitterträger. Diese haben die vorn genannten Elemente (DE-OS 27 37 859). Dabei werden die Obergurte zumeist genauso wie die Untergurte ausgeführt, in der Regel als Rundrohre. Bei Gitterträgern für Gerüste mit Lochscheiben und Anschlußköpfen zur Verbindung vertikaler und nicht-vertikaler Elemente ist nur am Obergurt ein Anschluß­kopf an jedem Ende vorgesehen, der auf eine am Gerüststiel befestigte Lochscheibe paßt. Der Untergurt wird in der Regel nach den statischen Bedingungen in einem, nicht auf das Rastermaß abgepaßten Abstand vorgesehen und mit geeigneten Anschlußmitteln für die Befestigung am vertikalen Gerüststiel an beliebiger Stelle, beispielsweise mit Klappschalen-Kupplungen oder dgl. ausgestattet oder mit einer Schrägstrebe zum Obergurt-Anschlußkopf abgestützt.Lattice girders are used in scaffolding to bridge large spans where simple horizontal support elements such as round tubes or profile bars are not sufficient. These have the elements mentioned above (DE-OS 27 37 859). The top chords are usually designed in exactly the same way as the bottom chords, usually as round tubes. In lattice girders for scaffolding with perforated disks and connection heads for connecting vertical and non-vertical elements, a connection head is only provided on the top chord at each end, which fits onto a perforated disk attached to the scaffold post. The lower chord is usually provided according to the static conditions at a distance that does not match the grid size and is equipped with suitable connection means for attachment to the vertical scaffold arm at any point, for example with clamshell couplings or the like, or with an oblique strut to the upper chord. Connection head supported.

Aus dem deutschen Gebrauchsmuster 69 25 375 ist ein Gitterträger für Decken- und Raumgerüste bekannt, dessen Obergurt aus einem nach oben offenen U-Profil besteht, in welches die endseitigen Haken von speziellen Gerüstrahmen­tafeln einhängbar sind. Diese Gitterträger werden mit Halb­kupplungen an den Gerüststielen befestigt. Durch die fehlende Abstimmung von Ober- und Untergurt auf an den Gerüststielen selbst unveränderbar befestigte Halteein­richtungen, wie Lochscheiben, ist die Sicherheit der oft in großen Höhen angebrachten Gitterträger relativ gering und erfordert bei der Montage besondere Kontrollen.From the German utility model 69 25 375 a lattice girder for ceiling and room scaffolding is known, the upper flange of which consists of an upwardly open U-profile, into which the end hooks of special scaffolding panels can be hung. These lattice girders are attached to the scaffold posts with half-couplings. Due to the lack of coordination of the upper and lower chord on holding devices, such as perforated disks, which are attached to the scaffolding posts themselves in an unchangeable manner, the safety of the lattice girders, which are often attached at great heights, is relatively low and requires special checks during assembly.

Aus US-PS 4,156,996 ist ein Gitterträger mit üblichen Rundrohren bekannt. An den Enden des Gitterträgers sind an besonderen, vor den Stirnflächen der Rundrohre befestigten, vertikal verlaufenden, aus Winkelprofilen gebildeten Abschlußstreben Haken angebracht, die in einzeln an den Vertikalstielen angebrachte Ösen eingehängt werden. Diese Spezialkonstruktion ist nicht auf stabile, im Rastermaß vorzusehende Verbindungselemente abgestimmt, an denen die verschiedensten Gerüstelemente sicher zu befestigen sind. Außerdem erfordert sie vor allem eine zusätzliche Abhubsicherung. Nach oben offene Einhängemöglichkeiten für die Haken von Standardgerüstböden sind nicht vorgesehen.From US-PS 4,156,996 a lattice girder with conventional round tubes is known. At the ends of the lattice girder are attached to special, in front of the end faces of the round tubes, vertically extending end struts formed from angle profiles hooks which are suspended in eyelets individually attached to the vertical rods. This special construction is not designed for stable, spaced-apart connecting elements, to which a wide variety of scaffolding elements can be securely attached. Above all, it requires additional protection against lifting. There are no provision for hanging hooks for standard scaffold floors that are open at the top.

Für den Aufbau von Gerüsten normaler Arbeitsbreite bis zu 70 oder 100 cm reichen die bisherigen einfachen horizontalen Tragriegel entsprechender Länge aus. Vielfach, insbesondere bei Deckenarbeiten, werden jedoch Arbeitsflächen größerer Breite benötigt, für die bisher recht aufwendige Konstruktionen für die Halterung an den Enden von Gerüstböden vorgesehen sind.For the construction of scaffolds with a normal working width of up to 70 or 100 cm, the previous simple horizontal support bars of corresponding length are sufficient. In many cases, especially for ceiling work, however, work surfaces of greater width are required, for which hitherto quite complex structures have been provided for mounting at the ends of scaffolding floors.

Der Erfindung liegt die Aufgabe zugrunde, ein Horizontal-­Tragelement für Gerüste mit den vorn angegebenen Merkmalen so auszustatten, daß es schnell mit Hilfe von Anschlußköpfen an allen Befestigungsstellen mit den vertikalen Gerüst-Stielen verbunden werden kann und daß die Einhängemittel der Gerüstböden unmittelbar in den Obergurt einhängbar sind.The invention has for its object to equip a horizontal support element for scaffolding with the features specified above so that it can be quickly connected to the vertical scaffolding posts with the help of connection heads at all attachment points and that the suspension means of the scaffolding floors directly into the top chord are attachable.

Erfindungsgemäß ist vorgesehen, daß der Obergurt als nach oben offenes U-Profil mit solchen Abmessungen ausgebildet ist, daß dem Rastermaß entsprechende, stirnseitig an Gerüstböden vorgesehene Einhängemittel unmittelbar einhängbar sind und daß Ober- und Untergurt an jedem Ende je einen zur zugehörigen Lochscheibe passenden Anschlußkopf aufweisen.According to the invention it is provided that the upper chord is designed as an upwardly open U-shaped profile with dimensions such that the hooking means corresponding to the grid dimension and provided on the end face of scaffolding floors can be directly hung in and that the upper and lower chord have a connection head matching the associated perforated disk at each end .

Dadurch, daß nunmehr vier Anschlußköpfe vorgesehen sind, die auf das Rastermaß der Lochscheiben passen, ist die Montage wesentlich vereinfacht und große Sicherheit sowie Bestimmtheit der Abstützungen geschaffen, so daß der Gitterträger auch der Querstabilität und Verwindungs-Steif­heit des ganzen Gerüstsystemes dient. Montage und Demontage sind schneller und einfacher als bei sonstigen Anschluß­mitteln. Dadurch, daß der Obergurt als nach oben offenes U-Profil passender Abemssungen gestaltet ist, werden keine weiteren Einhänge-Hilfsmittel benötigt und die Klauen, Haken, Halteschienen oder dgl. der Gerüstböden können unmittelbar eingehängt und mit den üblichen schnell montierbaren Sicherungsmittel gesichert werden. So lassen sich Gerüstfelder von beliebiger Breite wesentlich einfacher gestalten, wobei die Breite durch das Rastermaß und die Tragfähigkeit der verwendeten Elemente des Gitter­trägers bestimmt ist, jedoch in üblichen Abmessungen problemlos realisierbar ist.The fact that four connection heads are now provided, which fit the grid dimension of the perforated disks, the assembly is considerably simplified and great security and certainty of the supports are created, so that the lattice girder also serves the transverse stability and torsional rigidity of the entire scaffolding system. Assembly and disassembly are faster and easier than with other connection means. Due to the fact that the top chord is designed as an open U-profile of suitable dimensions, no further attachment aids are required and the claws, hooks, holding rails or the like of the scaffolding floors can be attached immediately and with the usual fast mountable securing means are secured. Scaffold bays of any width can thus be made much simpler, the width being determined by the grid size and the load-bearing capacity of the elements of the lattice girder used, but can be easily implemented in the usual dimensions.

Gelegentlich wird auf solchen Gitterträgern, die zur Über­brückung von Durchgängen oder dgl. eingesetzt sind, in der Mitte oder in einem anderen, dem Gerüst-Rastersystem entsprechenden Abstand von den Stielen eine Einrichtung benötigt, um mit vertikalen Gerüststielen weiter nach oben bauen zu können. Bei bisherigen Rundrohr-Gitterträgern sind in der Regel in der Mitte einfache Zapfen dafür befestigt. Diese würden bei dem Gitterträger nach der Erfindung in den meisten Fällen störend sein. Wenn sie benötigt werden, sollen sie jedoch schnell aufsetzbar sein. Deshalb sieht eine weitere Ausbildung der Erfindung vor, daß ein Anschluß-Verbinder vorgesehen ist, welcher eine nach unten offene U-förmige, auf die Außenmaße des Obergurtes passende, mit Sicherungsmitteln ausgestattete Halterung für einen in die unteren Enden von Gerüststielen passenden vertikalen Zapfen aufweist. Eine solche Halterung kann als ein nach unten offenes, umgebogenes U-förmiges Blech, welches über den Obergurt nach unten vorsteht und Horizontalbohrungen für unter dem Obergurt quer durchgeführte Schrauben aufweist, ausgebildet sein.Occasionally on such lattice girders, which are used for bridging passages or the like, in the middle or in another, corresponding to the scaffolding grid system, a device is required in order to be able to build further upwards with vertical scaffolding stems. In previous round tubular lattice girders, simple pins are usually attached in the middle. In the case of the lattice girder according to the invention, these would be troublesome in most cases. If they are needed, however, they should be quick to put on. Therefore, a further embodiment of the invention provides that a connection connector is provided which has a downwardly open U-shaped, fitting to the outer dimensions of the top chord, equipped with securing means for a vertical pin which fits into the lower ends of scaffolding posts. Such a holder can be designed as a downwardly open, bent U-shaped sheet which protrudes downward above the upper chord and has horizontal bores for screws passed transversely under the upper chord.

Weitere Einzelheiten, Ausgestaltungen, Vorteile, Merkmale und Gesichtspunkte der Erfindung sind in dem nachfolgenden, anhand der Zeichnungen abgehandelten Beschreibungsteil behandelt.Further details, refinements, advantages, features and aspects of the invention are dealt with in the following description section, which is dealt with on the basis of the drawings.

Das Gerüst 10 hat vertikale Gerüststiele 11, Horizontal­riegel 12, eine Arbeitsfläche 14 und Gitterträger 15. Die Gerüststiele 11 stehen auf mittels Schrauben höhenein­stellbaren Gerüstfüßen 16 und haben im Abstand 18 des Rastersystems horizontal angeordnete Lochscheiben 20 üblicher Art. Auf diesen sind die Horizontalriegel 12 und die Gitterträger 15 mit Hilfe von üblichen Anschluß­köpfen 21 befestigt. Diese werden auf die Lochscheiben 20 aufgesteckt und Keile 22 werden durchgesteckt und fest­geschlagen. Die Arbeitsfläche 14 ist hier von sechs neben­einander liegenden, üblichen Gerüstböden 23 gebildet. Diese haben an jedem Ende je zwei nach unten offene Einhänge­klauen 24.The scaffold 10 has vertical scaffold posts 11, horizontal bars 12, a work surface 14 and lattice girders 15. The scaffold posts 11 stand on scaffold feet 16 which are height-adjustable by means of screws and have horizontally arranged perforated disks 20 of a conventional type at a distance 18 from the grid system. On these are the horizontal bars 12 and Lattice girder 15 fastened with the aid of conventional connection heads 21. These are put on the perforated disks 20 and wedges 22 are pushed through and knocked down. The working surface 14 is formed here by six adjacent, usual scaffolding floors 23. At each end, these have two hanging claws 24 which are open at the bottom.

Der Gitterträger 15 hat einen Obergurt 25, der unmittelbar als nach oben offenes U-Profil ausgebildet ist, wie es inbesondere Fig. 3 deutlich zeigt. Der Untergurt 26 ist als Rundrohr ausgebildet. Vertikalstäbe 27 und Diagonalstäbe 28 bilden die üblichen Verstrebungen und bestehen aus geeignet dimensionierten Rundrohren oder sonstigen Profilstäben. An jedem Ende 29.1 bis 29.4 ist je ein Anschlußkopf 21 in üblicher Art befestigt, wie es inbesondere Fig. 2 deutlich zeigt. Dabei liegen die Anschlußköpfe 21 und Untergurt 26 und Obergurt 25 im Abstand 18, der dem Rastermaß des Gerüstsystems und dem Abstand der Lochscheiben 20 entspricht. Es kann auch ein doppelter Abstand gewählt werden. Wichtig ist, daß die Anschlußköpfe direkt auf die Lochscheiben passen und nicht andere Anschluß-Hilfsmittel erforderlich sind.The lattice girder 15 has an upper chord 25 which is formed directly as a U-profile open at the top, as is clearly shown in FIG. 3 in particular. The lower flange 26 is designed as a round tube. Vertical bars 27 and diagonal bars 28 form the usual struts and consist of suitably dimensioned round tubes or other profile bars. At each end 29.1 to 29.4, a connection head 21 is fastened in the usual manner, as is particularly shown in FIG. 2. The connection heads 21 and lower flange 26 and upper flange 25 are at a distance 18 which corresponds to the grid dimension of the scaffolding system and the distance between the perforated disks 20. A double distance can also be selected. It is important that the connection heads fit directly onto the perforated disks and that no other connection aids are required.

Da der Obergurt 25 unmittelbar als U-Profil ausgebildet ist und damit auf die übliche Länge der Gerüstböden 23 samt ihren Einhängeklauen 24 unmittelbar abgestimmt ist, kann man die Gerüstböden 23 unmittelbar einhängen und somit eine der Länge 30 des Gitterträgers, die einer Standardlänge von horizontalen Gerüstelementen entsprechen sollte, entsprechende, breite Arbeitsfläche (14), insbesondere für Arbeiten unter Decken von Hallen, Kirchen oder in Industrieanlagen aufbauen, wobei die Gerüstböden 23 zur Horizontalaussteifung beitragen. Auf den anderen Seiten der Gerüsstiele 11 können weitere Gitterträger 15 an den entsprechenden Lochscheiben befestigt werden, sodaß auch nebeneinanderliegend mehrere Gerüstfelder mit Gerüst­böden 23 zu einer großen Arbeitsfläche zusammengefügt werden können.Since the top chord 25 is designed directly as a U-profile and is thus directly matched to the usual length of the scaffolding floors 23 including their hooking claws 24, one can hook in the scaffolding floors 23 directly and thus one of the length 30 of the lattice girder, which is a standard length of horizontal scaffolding elements should correspond to a corresponding, wide working surface (14), in particular for work under ceilings in halls, churches or in industrial plants, the scaffolding floors 23 contributing to the horizontal stiffening. On the other sides of the scaffolding stems 11, additional lattice girders 15 can be attached to the corresponding perforated disks, so that several scaffolding fields with scaffolding floors 23 can also be joined together to form a large work surface.

Wünscht man an beliebiger Stelle auf dem Gitterträger einen Gerüststiel aufzustellen, so kann man, wie es Fig. 3 veranschaulicht, einen Anschluß-Verbinder 40 aufstecken. Dieser besteht aus einer Halterung 41 mit einem darauf befestigten Zapfen 42. Die Halterung 41 ist als nach unten offenes U-förmig gebogenes Blechteil mit zwei Seitenwänden 43.1 und 43.2 gebildet, auf deren oberem horizontalen Steg 44 der Zapfen 42 festgeschweißt ist. Die Seitenwände 43.1 und 43.2 liegen in einem Abstand 45 voneinander, der der Breite des Obergurtes 25 genau entspricht. Die Seitenwände 43.1 und 43.2 sind länger als die Höhe 46 des Obergurtes 25, so daß untere Befestigungsabschnitte 47 gebildet sind. Durch diese erstrecken sich im ausreichenden Abstand voneinander Horizontalbohrungen, durch welche Befestigungsbolzen 48 mit Gewinde und aufgeschraubten Muttern 49 gesteckt sind. Es können auch Keilsicherungsmittel vorgesehen sein.If one wishes to set up a scaffold post at any point on the lattice girder, then, as illustrated in FIG. 3, a connection connector 40 can be attached. This consists of a holder 41 with a pin 42 fastened thereon. The holder 41 is formed as a downwardly open U-shaped bent sheet metal part with two side walls 43.1 and 43.2, on the upper horizontal web 44 of which the pin 42 is welded. The side walls 43.1 and 43.2 are at a distance 45 from one another which corresponds exactly to the width of the upper flange 25. The side walls 43.1 and 43.2 are longer than the height 46 of the upper flange 25, so that lower fastening sections 47 are formed. Horizontal bores extend through these at a sufficient distance from one another, through which fastening bolts 48 with threads and screwed-on nuts 49 are inserted. Wedge securing means can also be provided.

Der Zapfen 42 hat einen unteren, dem Außendurchmesser der Gerüststiele 11 entsprechenden, rohrförmigen Abstands­teil 50 und einen dem Innendurchmesser der Gerüststiele 11 entsprechenden Einsteckzapfen 51. Dieser ist mit einer Durchsteckbohrung 52 zum Einstecken eines Sicherungsstiftes ausgestattet. Die Halterung 40 kann, wie ersichtlich, an beliebiger Stelle auf dem Obergurt befestigt werden. Dabei ist die Lage so zu wählen, daß nicht Einhängeklauen 24 im Wege sind. Gerüststiele können dann in üblicher Art und dem Rastermaß entsprechend aufgesteckt werden, so daß man ein schmaleres Gerüst weiterbauen kann. Gitterträger und Halterung können aus Stahlrohr und Stahlblech oder Walz­profil und entsprechendem Zubehör gefertigt und verzinkt sein oder auch aus Leichtmetall der im Gerüstbau üblichen Art hergestellt und zusammengesetzt sein.The pin 42 has a lower, tubular spacer 50 corresponding to the outer diameter of the scaffold posts 11 and a plug-in pin 51 corresponding to the inner diameter of the scaffold posts 11. This is equipped with a push-through bore 52 for inserting a securing pin. As can be seen, the holder 40 can be fastened anywhere on the upper chord. The location is to be chosen so that there are no claws 24 in the way. Scaffolding stems can then be attached in the usual manner and according to the grid dimension, so that a narrower scaffolding can be built on. Lattice girders and brackets can be made of tubular steel and sheet steel or rolled sections and corresponding accessories and galvanized, or they can also be made and assembled from light metal of the type commonly used in scaffolding.
