Abstract
Description
Die Erfindung betrifft eine Gerüstrahmentafel mit Längsholmen aus geschlossenen Leichtmetall-Hohlprofilen mit einer Auflage für eine, eine Gang- und Arbeitsfläche bildende Platte und mit den Längsholmen durch Schweißung verbundenen Querverbindungen und mit im Bereich der Enden vorgesehenen Klauen zum Einhängen in die Tragkonstruktion des Gerüstes.The invention relates to a scaffolding panel with longitudinal spars made of closed light metal hollow profiles with a support for a plate forming a walkway and work surface and with the longitudinal spars connected by welding cross-connections and with claws provided in the region of the ends for hanging in the supporting structure of the scaffold.
In DE-OS 35 39 507 ist eine Gerüstrahmentafel vorausgesetzt worden, die aus Aluminiumprofilen zusammengeschweißt wurde. Die Konstruktion nach DE-OS 35 39 507 befaßt sich unter anderem mit Profilen für Gerüstrahmentafeln aus Leichtmetall-Strangpreßhalbzeugen, die einen Auflageschenkel für die Tafel aufweisen, wobei der Deckschenkel gleich lang wie der Auflageschenkel ist. Das ist für die Montage nachteilig und vielfach nicht notwendig. Der Aufnahmeraum für die Platte bedingt im Innern einen Absatz. Im übrigen sieht dies bekannte Konstruktion eingenietete Querleisten mit daran angebrachten kleinen Klauen zum Einhängen in entsprechende U-Profile von Gerüsten vor.In DE-OS 35 39 507 a scaffolding panel has been assumed which was welded together from aluminum profiles. The construction according to DE-OS 35 39 507 deals, inter alia, with profiles for scaffold panels made of light metal extruded semi-finished products which have a support leg for the board, the cover leg being the same length as the support leg. This is disadvantageous for assembly and is often not necessary. The receiving space for the plate requires a shoulder on the inside. In addition, this known construction provides riveted cross bars with small claws attached to them for hanging in corresponding U-profiles of scaffolding.
Es gibt viele Gerüste, inbesondere Turm- und Fahrgerüste, bei denen an langestreckten Elementen Einrastklauen mit größeren nach unten offenen Vertiefungen und automatisch von unter hintergreifenden Sicherungsfingern üblich sind. Diese werden vor allem für die Schnellmontage kleiner Gerüste benötigt. Dabei gibt es Konstruktionen, bei denen die Diagonalstäbe in die gleichen Querriegel eingreifen müsen und andererseits die Platten soweit wie möglich bis zum Ende durchzulaufen haben. So hat man Lösungen zu finden, bei denen die Endbereiche der Gerüstrahmentafeln wenigstens über einem Teil ihrer Länge und Breite frei sind, so daß von unten Klauen durchgreifen können, um Diagonalstäbe anzuschließen. Desweiteren werden Durchstiegsöffnungen über den Leitern oder ggf. Treppen benötigt. Dabei hängt man die Leitern zweckmäßig auch in die Querriegel ein, in die auch die Gerüstrahmentafeln, die auch als Fahrgerüstböden bezeichnet werden, eingehängt werden. Dann ist es zweckmäßig, wenn im Bereich des Endes der Gerüstrahmentafel, dort, wo die Durchstiegsöffnung ist, keine Querverbindungen vorgesehen, sondern nur die Längsholme durchgeführt sind. Bisherige Gerüstrahmentafeln boten hier nur wenig Ausführungsmöglichkeiten.There are many scaffolds, especially tower and mobile scaffolds, in which snap-on claws with larger downwardly open recesses and automatically from under-reaching safety fingers are common on elongated elements. These are mainly needed for the quick assembly of small scaffolding. There are constructions in which the diagonal bars have to engage in the same crossbars and on the other hand have to run through the panels as far as possible to the end. Solutions have to be found in which the end regions of the scaffolding panels are free at least over part of their length and width, so that claws can reach through from below to connect diagonal bars. Furthermore, access openings above the ladders or stairs may be required. In this case, the ladders are appropriately hung in the crossbars, in which the scaffold panels, which are also referred to as mobile scaffold floors, are hung. It is then expedient if, in the area of the end of the scaffolding panel, where the access opening is, no cross connections are provided, but only the longitudinal spars are made. Previous scaffolding panels offered only a few design options here.
Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte Gerüstrahmentafel der eingangs genannten Art zu schaffen, bei der die Endbereiche und die Auflage- oder Einrast-Klauen so gestaltet sind, daß man zwischen den Einrastklauen der Gerüstrahmentafeln weitere Einhängemöglichkeiten und ggf. Durchstiegsmöglichkeiten hat.The invention has for its object to provide an improved scaffolding panel of the type mentioned, in which the end regions and the support or snap-in claws are designed so that there are further suspension options and possible access options between the snap-in claws of the scaffolding panels.
Erfindungsgemäß ist vorgesehen, daß in die geradlinige Innenwände aufweisenden Längsholme geradlinige Fortsätze von aus Blech, vorzugsweise Stahlblech gebogenen Einrastklauen eingesteckt und mit wenigstens einer Längsholmwand durch Nietung verbunden sind, wobei die Einrastklauen dem Rohrdurchmesser von Bodentragriegeln entsprechende halbzylinderförmige nach unten offene Vertiefungen aufweisen, die im vorderen Endbereich in eine gerundete Abschluß- und Haltenase übergehen und wobei innerhalb der kastenartigen Einrastklauen gelagerte, gegen Federn verschwenkbare Sicherungsfinger vorgesehen sind, die den unter dem Auflagebereich liegenden Rohrteil des Bodentragriegels umgreifen und wobei die als Rohre ausgebildeten Querverbindungen in Abständen von den Enden der Längsholme liegen, die mindestens die Länge der Fortsätze der Einrastklauen betragen, und wobei in der Ebene der oberen Längsholmwände ein kurzer, den Rand der Platte geringfügig übergreifender Stütz- und Schutzschenkel vorgesehen ist, unter dem in einem der Dicke der Platte entsprechenden Abstand der Plattenstützschenkel nach innen ragt, auf dem die Platte mit Nieten befestigt ist.It is provided according to the invention that straight extensions of sheet metal, preferably sheet steel, snap-in claws are inserted into the longitudinal bars having straight inner walls and connected to at least one longitudinal bar wall by riveting, the snap-in claws having semi-cylindrical depressions which are open at the bottom and correspond to the tube diameter of floor bars Merging the end area into a rounded end and retaining lug and wherein within the box-like latching claws, spring springs that can be pivoted against springs are provided, which encompass the tube part of the floor support bar lying under the support area and the cross connections designed as tubes lie at a distance from the ends of the longitudinal bars, which are at least the length of the extensions of the latching claws, and wherein in the plane of the upper longitudinal spar walls there is a short support and protective leg which slightly overlaps the edge of the plate is under which the plate support leg projects at a distance corresponding to the thickness of the plate, on which the plate is fastened with rivets.
Man verwendet hier die an sich für andere Gerüstelemente, insbesondere für Diagonalstäbe bekannten Einrastklauen aus Stahlblech, sieht jedoch Fortsätze vor, mit deren Hilfe sie in den im Innern glatt rechteckigen Längsholmen befestigt werden. Die Obergurte der Längsholme bilden im Bereich der Längsränder den obersten Teil der Gerüstrahmentafel und die eingesetzte Platte liegt zwischen den Längsholmen. Der nur kurze Stütz- und Schutzschenkel ermöglicht mit geringem Aufwand ein leichtes Montieren, bietet jedoch einen ausreichenden Kantenschutz und gewährleistet noch eine zusätzliche Einspannung für die Platte, die vorzugsweise aus wasserfestem Sperrholz mit quer zur Längsrichtung der Gerüstrahmentafel verlaufender Faser der Deckfurniere ausgebildet ist.The snap-in claws made of sheet steel, which are known per se for other scaffolding elements, in particular for diagonal bars, are used here, but projections are provided, with the aid of which they are fastened in the longitudinal bars, which are smoothly rectangular on the inside. The upper straps of the longitudinal spars form the uppermost part of the scaffold panel and the in the area of the longitudinal edges inserted plate lies between the longitudinal spars. The only short support and protective leg enables easy assembly with little effort, but offers sufficient edge protection and also ensures additional clamping for the panel, which is preferably made of waterproof plywood with the veneer fiber running transversely to the longitudinal direction of the scaffolding panel.
Infolge der Maßnahme die Querverbindung mit Abstand zum Ende der Platte vorzusehen ergibt sich leicht eine Möglichkeit zum Einstecken der Fortsätze der Einrastklauen, weil man kein Querverbindungen vorsehen kann, die in die Enden der Längsholme einzustecken sind. So geht man auch wieder zu der an sich nicht so günstigen Art des Verschweißens über, die jedoch durch den Abstand bedingt ist und das Einstecken zur Befestigung der Klauen zuläßt. Dabei kann man vorteilhaft die Querverbindung einer Seite in einem der Größe einer Durchstiegsöffnung entsprechenden Abstand vom Ende der Längsholme einschweißen. So erhält man ein einfach aufgebautes, sicher zu handhabendes, stabiles Element für das Zusammenwirken von Gerüstrahmentafel und dazwischenzuhängender Leiter, wobei die Durchstiegsöffnung mit einer entsprechenden Klappe zu versehen ist. Weitere Einzelheiten, Merkmale, Ausgestaltungen und Vorteile der Erfindung ergeben sich auch aus dem nachfolgenden Teil der anhand der Zeichnungen abgehandelten Beschreibung sowie ggf. weiteren Ansprüchen.As a result of the measure to provide the cross connection at a distance from the end of the plate, there is easily a possibility of inserting the extensions of the latching claws, because no cross connections can be provided, which are to be inserted into the ends of the longitudinal spars. So you go back to the not so cheap way of welding, which is, however, due to the distance and allows the insertion for fastening the claws. It is advantageous to weld in the transverse connection of one side at a distance from the end of the longitudinal spars that corresponds to the size of a manhole. The result is a simply constructed, safe to handle, stable element for the interaction of the scaffolding panel and the ladder to be hung in between, the access opening being provided with a corresponding flap. Further details, features, configurations and advantages of the invention also result from the following part of the description dealt with on the basis of the drawings and, if appropriate, further claims.

Die Gerüstrahmentafel 10 hat zwei Längsholme 11.1 und 11.2, die aus einem Leichtmetall-Strang-Preß-Profil-Halbzeug gefertigt sind, dessen Querschnitt in den Figuren 4 und 5 veranschaulicht ist. An ihren Enden sind Einrastklauen 12 befestigt, die untereinander alle gleich sind. Auf den Plattenstützschenkeln 13 der Längsholme 11 liegt die die Gang- und Arbeitsfläche bildende Platte 14 auf, die an den Plattenstützschenkeln 13 mit Hilfe von im Abstand angeordneten Nieten 15 befestigt ist.The
Die beiden Längsholme 11.1 und 11.2 sind durch Querverbindungen 16.1 und 16.2 verbunden. Diese sind - wie aus den Fig. 2, 3 und 4 hervergeht - als etwa quadratförmige Rohre ausgebildet. Sie sind mit ihren Enden 16.3 stumpf vor die Seitenwände 17 der Längsholme 11 gestoßen und an diesen mit Hilfe der Schweißnähte 18 angeschweißt. Die obere Auflagefläche 19 liegt auf der gleichen Höhe wie die Auflagefläche 20 des Plattenstützschenkels 13, so daß die Platte 14 auch von den Querverbindungen 16 getragen ist. Wie aus Fig.1 ersichtlich, ist die Platte 14 auch an den Querverbindungen mit Nieten 15 befestigt.The two longitudinal spars 11.1 and 11.2 are connected by cross connections 16.1 and 16.2. As shown in FIGS. 2, 3 and 4, these are designed as approximately square tubes. Their ends 16.3 are butted in front of the
Die Querverbindung 16.1 liegt im Abstand 21 vom Ende 22.1 der Längsholme. Die andere Querverbindung 16.2 liegt im Abstand 23 vom in Fig. 1 rechten Ende 22.2 der Längsholme 11. Der Abstand 21 beträgt wenige Zentimeter, beispielsweise etwa 5 cm. Er ist durch das Ende 14.1 der Platte 14 überdeckt. Es ist jedoch hinreichend Platz um Klauen hindurchzustecken. Der Abstand 23 beträgt mehrere Dezimeter und ist so groß wie die Durchstiegsöffnung. In seinem Bereich ist zwischem den Längsholmen 11 keine Querverbindung vorgesehen. Eine Durchstiegsklappe 25 ist mit Scharnieren 26 am Längsholm 11.2 nach oben schwenkbar befestigt und legt sich mit ihrem freien Ende 25.1 auf den Plattenstützschenkel 13 des Längsholmes 11.1 auf. So ergibt sich eine bis zum Ende freie Durchstiegsöffnung, in der man eine Leiter gut einhängen kann. Die beiden Querverbindungen ergeben eine gut Stabilität. Da sie in einem nicht allzugroßen Abstand liegen,ergeben sich auch beim Schweißen keine zu großen Spannungen.The cross connection 16.1 is at a
Die Längsholme 11 sind, wie aus den Fig. 4 und 5 ersichtlich, aus einem hochkant stehenden Rechteck-Strang-Preß-Profil aus Leichtmetall gefertigt und auf Länge abgeschnitten. Die obere Wand 27 ist außen mit einer Gleitschutzriffelung 28 versehen. Jenseits der gerade durchgeführten Innenwand 17 ist auf Höhe der oberen Wand 27 ein kurzer Stütz- und Schutzschenkel 29 vorgesehen. Im Abstand 31 unterhalb desselben liegt der für die Nietung ausreichend breitausgebildete Plattenstützschenkel 13, der an die Innenwand 17 rechtwinklig angesetzt ist. Die Außenwand 32 ist innen und außen glattflächig. Die Innenwand 17 ist innen völlig glattflächig. Die vier Wände gehen in den Ecken mit Rundungen über. Die untere Wand 33 hat eine Stufe 34.The
Die Einrastklauen 12 sind von kastenartigen Stahlblechgehäusen 35 bekannter Konfiguration gebildet und haben eine halbzylinderförmige nach unten offenen Vertiefung 36 mit der sie auf die Querriegel des Gerüstes aufgelegt werden. Im vorderen Endbereich 37 ist eine gerundete Abschluß- und Haltenase 38 vorgesehen. Im Innern ist ein Lager 39 für einen Sicherungsfinger 40 vorgesehen, der in bekannter Weise gegen die Kraft der Feder 41 hochgeschwenkt werden kann und der gemäß der in Fig. 3 dargestellten Position durch seine Ausbildung und die Lage seines Gelenkpunktes zur automatischen Sicherung und zum fester Zuziehen beim Abheben führt. Solche Einrastklauen werden an verschiedenen Gerüstelementen in großer Zahl benutzt. Hier haben sie erfindungsgemäß Fortsätze 43, die von vier rechtwinklig zueinander stehenden Befestigungsschenkeln 44.1 gebildet werden. Diese liegen passend an den Wänden 17, 27, 32 und 33 der Längsholme 11.1 und 11.2 Zumindest an der Außenwand 32 sind die Befestigungsschenkel 44.1 durch mindestens zwei Nieten 46 befestigt. Von den Vertiefungen 36 zum Ende 22.1 der Platte 14 ist ein ausreichender Platz vorhanden, um weitere Halteklauen durchgreifen zu lassen und so Diagonalstäbe anschließen zu lassen. Gleichartig liegt das Ende 25.1 der Durchstiegsklappe 25 hinreichend von einem entsprechenden Querriegel beabstandet, um die Einrastklauen der Leiter hindurchgreifen zu lassen.The
So ist eine aus einfachen,leicht herzustellenden, sicher im Dauergebrauch zu handhabenden Teilen aufgebaute Gerüstrahmentafel, insbesondere als Fahrgerüstboden geschaffen.In this way, a scaffold panel is made up of simple, easy-to-manufacture parts that can be safely used in long-term use, in particular as a scaffold floor.
