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 diese 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 scaffolding 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.

Durchstiegsöffnungen und Begehungsfragen für sinnvolle Gestaltung im Bezug auf Leitern und die Öffnung sowie Einrastklauen sind hier nicht behandelt.Access openings and inspection questions for sensible design in relation to ladders and the opening as well as snap-in claws are not dealt with here.

Die amerikanische Patentschrift US-A-2 619 390 zeigt ein Gerüst, dessen Rahmentafel Längsholme aus Rundrohr hat. An den Enden der Rundrohre sind Klauen befestigt, die schräg liegende, axial gegen Federdruck verschiebbare Sicherungsstifte aufweisen. Deren Enden greifen im Sicherungszustand unter die aus Rundrohr gebildeten horizontalen Tragriegel von Vertikalrahmen, über welche die Klauen greifen. Querverbindungen im Abstand von den Enden der Rahmentafel scheinen eingeschweißt zu sein und tragen diagonal einhängbare Auszieh-Hilfsstreben. Fragen des Durchstiegs und der sinnvollen Gestaltung von Klauen mit Schwenksicherungen sowie Fragen der Gestaltung von Auflagen und Schutzprofilen sind nicht Gegenstand dieser Veröffentlichung.The American patent US-A-2 619 390 shows a scaffold whose frame panel has longitudinal bars made of round tube. Claws are attached to the ends of the round tubes, which have inclined locking pins that can be moved axially against spring pressure. In the secured state, their ends engage under the horizontal support bars of vertical frames formed from round tubing, over which the claws grip. Cross connections at a distance from the ends of the frame panel appear to be welded in and carry diagonally attachable pull-out struts. Questions regarding the passage and the sensible design of claws with swivel locks as well as questions regarding the design of supports and protective profiles are not the subject of this publication.

Die FR-A-2 048 105 zeigt ein Gerüst mit Innenleiter und Durchstiegsöffnung mit Klappe. Die Gerüstrahmentafeln haben als Längsholme Rundrohre mit in sie eingesetzten Klauen, mit einfachen Sicherungsfingern. Im Bereich des Endes der Gerüstrahmentafel, welchem die Durchstiegsöffnung benachbart liegt, ist eine Querverbindung vorgesehen. Diese reicht weiter in den Durchstiegs- und Begehungsraum hinein als die Vorderkanten der Stufen und ist von einem getrennten Brettabschnitt abgedeckt, der größer als die Stufen der Leiter ist. Mit der Befestigung der die Trittfläche bildenden Platte auf besonderen Schenkeln der Längsholme mit Schutz der Plattenkanten befaßt sich die Schritt nicht. Beim Durchstieg besteht die Gefahr von Unfällen.FR-A-2 048 105 shows a scaffold with an inner conductor and a manhole with a flap. The scaffold panels have longitudinal tubes with round tubes with claws inserted into them, with simple securing fingers. A cross connection is provided in the area of the end of the scaffolding panel, which is adjacent to the access opening. This extends further into the access and access area than the front edges of the steps and is covered by a separate board section that is larger than the steps of the ladder. The step is not concerned with the fastening of the plate forming the step surface on special legs of the longitudinal spars with protection of the plate edges. There is a risk of accidents when climbing through.

GB-A-2 074 225 zeigt eine Gerüstrahmentafel, deren Enden auf nach oben offene Winkelprofile aufgelegt und mit untergreifenden Haken gesichert werden. Dieser Montageraum ist von Abdeckklappen überbrückt. Wegen dieser endseitigen Auflage ist die dem Ende nächste Querverbindung in einem kleinen Abstand vom Ende vorgesehen, so daß die Abhubsicherung betätigt werden kann. Eine Durchstiegsöffnung mit Berücksichtigung der Sicherheitsfragen beim Besteigen der Leiter oder Treppe ist nicht vorgesehen und nicht Gegenstand dieser Druckschrift.GB-A-2 074 225 shows a scaffold board, the ends of which are placed on upwardly open angle profiles and secured with hooks below. This assembly space is bridged by cover flaps. Because of this end support, the cross connection closest to the end is provided at a small distance from the end, so that the anti-lift device can be actuated. A passage opening taking into account the safety issues when climbing the ladder or stairs is not provided and is not the subject of this document.

Es gibt viele Gerüste, inbesondere Turm- und Fahrgerüste, bei denen an langestreckten Elementen Einrastklauen mit größeren nach unten offenen Vertiefungen und automatisch von unten 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 müssen 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, in particular tower and mobile scaffolds, in which snap-on claws with larger downwardly open recesses and locking fingers engaging automatically from below 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, the plates have to go through 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 expediently also suspended in the crossbars in which the scaffold panels, which are also referred to as mobile scaffold floors, are suspended. 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 an improved scaffolding table of the beginning named type to create, in which the end portions and the support or snap-in claws are designed so that between the snap-in claws of the scaffold panels there are further suspension options and, if necessary, access options.

Erfindungsgemäß sind folgende Merkmale vorgesehen:

  • - die Klauen sind als Einrastklauen (12) ausgebildet und aus Blech, vorzugsweise Stahlblech, gebogen;
  • - in die Enden der Längsholme sind geradlinige Fortsätze von Einrastklauen eingesteckt;
  • - die Fortsätze der Einrastklauen sind mit wenigstens einer Längsholmwand durch Nietung verbunden;
  • - die Einrastklauen haben dem Rohrdurchmesser von Bodentragriegeln entsprechende halbzylinderförmige, nach unten offene Vertiefungen;
  • - die Vertiefungen gehen im vorderen Endbereich jeweils in eine gerundete Abschluß- und Haltenase über;
  • - innerhalb der kastenartigen Einrastklauen sind Sicherungsfinger vorgesehen und gelagert;
  • - die Sicherungsfinger sind gegen Federn verschwenkbar und umgreifen den unter dem Auflagebereich liegenden Rohrteil des Bodentragriegels;
  • - die als Rohre ausgebildeten Querverbindungen sind mit den Längsholmen (11.1;11.2) durch Schweißung verbunden und liegen in Abständen von den Enden der Längsholme, die mindestens die Länge der Fortsätze der Einrastklauen betragen;
  • - die eine endseitige Querverbindung ist in einem der Größe einer Durchstiegsöffnung entsprechenden Abstand von diesem Ende der Längsholme eingeschweißt;
  • - der Stütz- und Schutzschenkel (29) decht nur die Kante der Platte (14) im Abstand von den Köpfen der Nieten (15) endend ab.
The following features are provided according to the invention:
  • - The claws are designed as snap claws (12) and bent from sheet metal, preferably sheet steel;
  • - Straight extensions of snap claws are inserted into the ends of the longitudinal spars;
  • - The extensions of the snap claws are connected to at least one longitudinal beam wall by riveting;
  • - The latching claws have semi-cylindrical, downwardly open depressions corresponding to the tube diameter of floor support bars;
  • - The depressions in the front end area each in a rounded end and holding nose;
  • - Safety fingers are provided and stored within the box-like snap claws;
  • - The securing fingers can be swiveled against springs and encompass the tubular part of the floor support bar below the support area;
  • - The cross connections designed as tubes are connected to the longitudinal spars (11.1; 11.2) by welding and are at a distance from the ends of the longitudinal spars that are at least the length of the extensions of the snap-in claws;
  • - The one end cross connection is welded at a distance corresponding to the size of a manhole from this end of the longitudinal spars;
  • - The support and protective leg (29) decht ends only the edge of the plate (14) at a distance from the heads of the rivets (15).

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 top chords of the longitudinal spars form the uppermost part of the scaffold panel in the area of the longitudinal edges and the plate used 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 formed from 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 keine 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 wird die Querverbindung einer Seite in einem der Größe einer Durchstiegsöffnung entsprechenden Abstand vom Ende der Längsholme eingeschweißt. 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 of providing 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 insertion for fastening the claws. The transverse connection of one side is welded in 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 scaffold 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 emerge from the following part of the description dealt with on the basis of the drawings and, if appropriate, further claims.

Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnungen erläutert.An embodiment of the invention is explained with reference to the drawings.

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 scaffolding panel 10 has two longitudinal spars 11.1 and 11.2, which are made from a light metal extruded profile semifinished product, the cross section of which is illustrated in FIGS. 4 and 5. Snap claws 12 are attached at their ends, all of which are identical to one another. The plate 14, which forms the aisle and working surface, lies on the plate support legs 13 of the longitudinal spars 11 and is fastened to the plate support legs 13 by means of rivets 15 arranged at a distance.

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 hervorgeht - 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. These are - as can be seen from FIGS. 2, 3 and 4 - formed as approximately square tubes. They are butted with their ends 16.3 in front of the side walls 17 of the longitudinal spars 11 and attached to them by means of the weld seams 18 welds. The upper bearing surface 19 is at the same height as the bearing surface 20 of the plate support leg 13, so that the plate 14 is also supported by the cross connections 16. As can be seen from FIG. 1, the plate 14 is also fastened to the cross connections with rivets 15.

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 distance 21 from the end 22.1 of the longitudinal spars. The other cross connection 16.2 is at a distance 23 from the right end 22.2 of the longitudinal spars 11 in FIG. 1. The distance 21 is a few centimeters, for example about 5 cm. It is covered by the end 14.1 of the plate 14. However, there is enough space to put claws through. The distance 23 is several decimeters and is as large as the access opening. In its area, no cross connection is provided between the longitudinal spars 11. A hatch 25 is pivotally attached to the longitudinal spar 11.2 with hinges 26 and rests with its free end 25.1 on the plate support leg 13 of the longitudinal spar 11.1. This results in a manhole that is free to the end, in which you can hang a ladder well. The two cross connections result in good stability. Since they are not too far apart, there are no excessive stresses during welding.

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 breit ausgebildete 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 longitudinal spars 11 are, as can be seen from FIGS. 4 and 5, made of an upright rectangular extruded profile made of light metal and cut to length. The upper wall 27 is provided on the outside with anti-slip corrugation 28. Beyond the inner wall 17 just carried out, a short support and protective leg 29 is provided at the level of the upper wall 27. At a distance 31 below it is the plate support leg 13 which is sufficiently wide for riveting and which is attached to the inner wall 17 at right angles. The outer wall 32 is smooth on the inside and outside. The inner wall 17 is completely smooth inside. The four walls are rounded in the corners. The lower wall 33 has a step 34.

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 Einrast- klauen der Leiter hindurchgreifen zu lassen.The latching claws 12 are formed by box-like sheet steel housings 35 of known configuration and have a semi-cylindrical recess 36 which is open at the bottom and with which they are placed on the crossbars of the frame. In the front end region 37, a rounded end and holding lug 38 is provided. Inside, a bearing 39 is provided for a securing finger 40, which can be pivoted up in a known manner against the force of the spring 41 and which, according to the position shown in FIG. 3, by its design and the position of its articulation point for automatic securing and tightening leads when taking off. Such claws are used in large numbers on various scaffolding elements. Here they have extensions 43 according to the invention, which are formed by four mutually perpendicular fastening legs 44.1. These are fitting on the walls 17, 27, 32 and 33 of the longitudinal spars 11.1 and 11.2. At least on the outer wall 32, the fastening legs 44.1 are fastened by at least two rivets 46. From the recesses 36 to the end 22.1 of the plate 14, there is sufficient space to allow further holding claws to reach through and thus to connect diagonal bars. Similarly, the end 25.1 of the access hatch 25 is sufficiently spaced from a corresponding cross bar to allow the snap-in claws of the ladder to reach through.

So ist eine aus einfachen,leicht herzustellenden, sicher im Dauergebrauch zu handhabenden Teilen aufgebaute Gerüstrahmentafel, insbesondere als Fahrgerüstboden geschaffen.Thus, a scaffold panel is made up of simple, easy-to-manufacture parts that can be handled safely in continuous use, in particular as a scaffold floor.

Die nachfolgend abgedruckte Zusammenfassung ist Bestandteil der Offenbarung der Erfindung: Die Gerüstrahmentafel hat Längsholme 11 mit glattem Kastenprofil. In dieses sind die Fortsätze (43) von Einrastklauen (12) aus Stahlblech eingesteckt und darin mit Nieten (46) gesichert. Im Abstand von den Enden liegende Querverbindungen (16.1. 16.2) sind eingeschweißt und bieten ausreichend Platz zum Einhängen von Diagonalstäben und/oder zur Bildung einer Durchstiegsöffnung und für das Einhängen einer Leiter.The summary printed below is part of the disclosure of the invention: The scaffolding panel has longitudinal spars 11 with a smooth box profile. The extensions (43) of snap-in claws (12) made of sheet steel are inserted into this and secured therein with rivets (46). Cross connections (16.1. 16.2) at a distance from the ends are welded in and offer sufficient space for hanging diagonal bars and / or for forming a manhole and for hanging a ladder.
