Abstract

The platform frame comprises closed extrusions (1) which form profiled bars and has parallel lengthwise side surfaces (1a,1b) with mating tongues (14) and grooves (11) on opposite sides, by which they are joined together. Similar profiled bars (1") form the lengthwise sides of the frame, but can have flat lengthwise outer sides (1b"). A profiled support runs along each transverse side of the platform, the platform being secured by it to the scaffolding. An integral parallel vertical rib (14a) can be formed on the tongue, fitting in a mating secondary groove (13a) in the bottom wall of the main groove (11). The wall thickness of the extrusions can be constant on all sides. <IMAGE>

Description

Die Erfindung betrifft eine Belagbühne für Gerüste, insbesondere Baugerüste oder dergleichen, wobei die Belagbühne aus mindestens zwei an ihren Längsseiten lösbar miteinander verbundenen, einstückigen Hohlprofilstäben zusammengesetzt ist.The invention relates to a covering platform for scaffolding, in particular scaffolding or the like, the covering platform being composed of at least two one-piece hollow profile bars which are detachably connected to one another on their longitudinal sides.

Ein derartige Belagbühne für ein Baugerüst oder dergleichen ist aus der DE-Offenlegungsschrift 43 23 381 A1 bereits bekannt. Die Hohlprofilstäbe sind dort in ganzer Länge ausgespart und im übrigen so geformt, daß sie an Hand dieser Aussparungen ineinander verschachtelt werden können und ein einziges Profil ausreicht, um - zusammen mit passenden Kopfstücken - eine komplette Belagbühne zusammenstellen zu können. Es sind Sicken vorgesehen, die der Formsteifigkeit und der Verbindung benachbarter Hohlprofilstäbe dienen.A covering platform of this type for scaffolding or the like is already known from DE Offenlegungsschrift 43 23 381 A1. The hollow profile bars are cut out there along their entire length and shaped in such a way that they can be nested into one another by means of these recesses and a single profile is sufficient to be able to put together a complete decking platform together with suitable head pieces. Corrugations are provided which serve to ensure the rigidity and the connection of adjacent hollow profile bars.

Die vorbekannte Anordnung erfordert allerdings, daß die nötige Formsteifigkeit beim Zusammenbau dadurch hergestellt wird, daß die benachbarten Hohlprofilstäbe miteinander vernietet werden, weil anders wegen der durchgehenden Aussparungen die Wanddicken der beteiligten Profile wesentlich hätten erhöht werden müssen. Die Sicken sind durchweg nach innen gerichtet, um geeignete Arretierungen benachbarter Hohlprofilstäbe zu ermöglichen, so daß sie zur Lagesicherung beim Stapeln mehrerer Belagbühnen nichts beitragen können. Es können auch nicht beliebig viele Hohlprofilstäbe ineinander verschachtelt werden, sondern stets nur zwei.The previously known arrangement, however, requires that the necessary dimensional rigidity is achieved during assembly by riveting the adjacent hollow profile bars together, because the wall thicknesses of those involved are different because of the continuous recesses Profiles should have been increased significantly. The beads are directed inward throughout to enable suitable locking of adjacent hollow profile bars, so that they cannot contribute to securing the position when stacking several covering platforms. It is also not possible to nest any number of hollow profile bars into each other, but always only two.

Die Erfindung hat sich deshalb die Aufgabe gestellt, eine Belagbühne der eingangs näher bezeichneten Art mit einfachen Mitteln betriebssicher zu gestalten und so auszubilden, daß auf zusätzliche Verbindungselemente zwischen den Hohlprofilstäben verzichtet und die Belagbühne trotzdem formstabil zusammengestellt werden kann; eine Stapelhilfe für die Belagbühnen ist ebenfalls erwünscht. Ferner soll die Anzahl der parallelen Hohlprofilstäbe beliebig sein, so daß eine vorteilhafte Breite dieser Hohlprofilstäbe nicht von der Breite der Belagbühne abhängig gemacht werden muß.The invention has therefore set itself the task of making a covering platform of the type described in more detail with simple means reliable and designed so that additional connecting elements between the hollow profile bars can be dispensed with and the covering platform can nevertheless be assembled in a dimensionally stable manner; a stacking aid for the covering platforms is also desirable. Furthermore, the number of parallel hollow profile bars should be arbitrary, so that an advantageous width of these hollow profile bars does not have to be made dependent on the width of the covering platform.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die Hohlprofilstäbe als geschlossene Strangpreßprofile ausgebildet sind, deren aneinanderstoßende, den Längsseiten des Tragrahmens parallele Seitenflächen auf der einen Seite des jeweiligen Hohlprofilstabes eine zu der Seitenfläche parallele, durchgehende Nut und auf dessen anderer Seite einen zu der Nut komplementär geformten Federspund aufweisen, wobei zwei benachbarte Hohlprofilstäbe miteinander durch die Nut des einen und den darin plazierten Federspund des anderen Hohlprofilstabes miteinander verzargbar sind, daß weiterhin die Längsseiten des Tragrahmens ebenfalls von je einem ähnlichen verzargbaren Hohlprofilstab gebildet werden, der aber an einer, die äußere Begrenzung des Tragrahmens bildenden Seite lediglich mit einer vorzugsweise glatten Seitenfläche versehen ist und nur an der jeweils anderen, einem benachbarten Hohlprofilstab zugewandten Seitenfläche mit einer Nut oder einem Federspund ausgestattet ist und daß schließlich die Querseiten des Tragrahmens jeweils aus einem Tragprofil bestehen, auf dem der Belag aufliegt und das zur Befestigung der Belagbühne an dem übrigen Baugerüst dient.According to the invention the object is achieved in that the hollow profile bars are designed as closed extruded profiles, their abutting side faces parallel to the long sides of the support frame on one side of the respective hollow profile bar a continuous groove parallel to the side face and on the other side one complementary to the groove have shaped spring bung, whereby two adjacent hollow profile rods can be tied together by the groove of one and the spring bung of the other hollow profile bar placed therein, that the longitudinal sides of the support frame are also each formed by a similar, retractable hollow profile bar, but at one, the outer boundary of the support frame forming side is only provided with a preferably smooth side surface and is only equipped on the other side surface facing an adjacent hollow profile rod with a groove or a spring bung and that the transverse sides of the support frame each consist of a support profile on which the covering rests and that serves to secure the platform to the rest of the scaffolding.

Eine erfindungsgemäße Belagbühne ist ohne Fachkenntnisse aus einzelnen Hohlprofilstäben zusammenbaubar und durch die Nut-Federspunt-Verbindung so fest verzargbar, daß eine stabile begehbare Fläche aus sehr leichten Strangpreßteilen zusammengestellt werden kann. Die Teile müssen weder verschraubt noch vernietet werden und können in beliebiger Anzahl aneinander gefügt werden; eine enge Teilung gewährleistet auf diese Weise auch bei Leichtbauprofilen durch die große Anzahl der das Widerstandsmoment bestimmenden senkrechten Stege der einzelnen Hohlprofilstäbe eine hohe Tragfähigkeit der Belagbühne.A covering platform according to the invention can be assembled from individual hollow profile bars without specialist knowledge and can be fixed so firmly through the tongue and groove connection that a stable, walkable surface can be put together from very light extruded parts. The parts do not have to be screwed or riveted and can be joined together in any number; In this way, a narrow division ensures a high load-bearing capacity of the covering platform even in the case of lightweight profiles due to the large number of vertical webs of the individual hollow profile bars that determine the section modulus.

Eine praktisch spielfreie Verbindung benachbarter Hohlprofilstäbe erfolgt beispielsweise dadurch, daß an dem Federspund eine parallele, senkrechte Stegleiste einstückig angeformt ist, die in eine in die untere Seitenwand der Nut eingetiefte, parallele Sekundärnut einschiebbar ist. Die Ausführung verbessert sowohl die Biegesteifigkeit in der Längsrichtung als auch die Formstabilität in der Querrichtung der Belagbühne.A practically backlash-free connection of adjacent hollow profile bars is achieved, for example, by integrally molding a parallel, vertical web strip on the spring bung, which can be inserted into a parallel secondary groove, which is recessed into the lower side wall of the groove. The design improves both the bending stiffness in the longitudinal direction and the dimensional stability in the transverse direction of the covering platform.

Die Hohlprofilstäbe können im wesentlichen mit allseits etwa gleicher Wandstärke ausgebildet sein, also einschließlich der Bereiche von Nut und Federspund. Eine solche Ausbildung ist technologisch günstig, weil bei ihrer Herstellung Wärmespannungen möglichst vermieden werden, die bei größeren Wanddickensprüngen auftreten können.The hollow profile bars can essentially be formed with approximately the same wall thickness on all sides, that is to say including the areas of the tongue and groove bung. Such training is technologically favorable because thermal stresses that can occur with larger wall thickness jumps are avoided as far as possible during their manufacture.

Besonders praktisch ist es, wenn die berandenden, die Längsseiten des Tragrahmens bildenden Hohlprofilstäbe auf ihrer als Trittfläche dienenden Deckfläche und der dieser gegenüberliegenden flächengleichen Bodenfläche mit jeweils mindestens einer Sicke versehen sind, die der glatten Seitenfläche benachbart und parallel ist, insbesondere, wenn die Sicke in der Deckfläche erhaben und diejenige in der Bodenfläche eingetieft ausgebildet ist, weil auf diese Weise - außer der verbesserten Formstabilität - die Voraussetzung dafür geschaffen ist, daß die Sicken so bemessen werden können, daß sie bei übereinander gelegten Belagbühnen mit aneinander anliegenden Belägen ineinander geraten und als Stapelhilfe eine gegenseitige Querverschiebung der Belagbühnen verhindern.It is particularly practical if the bordering hollow profile bars that form the long sides of the support frame are each provided with at least one bead on their top surface that serves as a tread surface and the flat surface opposite this surface, which is adjacent and parallel to the smooth side surface, in particular if the bead in the top surface is raised and that is recessed in the bottom surface, because in this way - in addition to the improved dimensional stability - the prerequisite is created for the beads to be dimensioned such that they come into contact with one another when decking platforms are placed one above the other and as Stacking aid to prevent mutual shifting of the covering platforms.

Die Belagbühne wird auf zweckmäßige Art vervollständigt, wenn das Tragprofil als U- oder L-Profil ausgebildet ist und die Hohlprofilstäbe auf dem unteren waagerechten, an dem senkrechten Steg des U- oder L-Profiles anschließenden Gurt aufliegen, wobei die Hohlprofilstäbe mit ihren Endbereichen zumindest teilweise an dem Tragprofil befestigt sein können. Es kann bereits ausreichend sein, die berandenden Hohlprofile an den Tragprofilen zu befestigen und die übrigen nur aufzulegen, insbesondere bei der Verwendung von U-Profilen.The covering platform is completed in an expedient manner if the supporting profile is designed as a U or L profile and the hollow profile bars rest on the lower horizontal belt adjoining the vertical web of the U or L profile, the hollow profile bars at least with their end regions can be partially attached to the support profile. It may already be sufficient to attach the bordering hollow profiles to the support profiles and only to hang up the others, especially when using U-profiles.

Die erfindungsgemäße Belagbühne ermöglicht es, die die Längsseiten der Belagbühne bildenden Hohlprofilstäbe gleich oder spiegelbildlich auszubilden; im letzteren Fall ist es vorteilhaft, wenn ein Hohlprofilstab beiderseits mit je einer Nut oder je einem Federspund versehen ist.The covering platform according to the invention makes it possible to design the hollow profile bars forming the long sides of the covering platform in the same way or in mirror image; in the latter case, it is advantageous if a hollow profile rod on both sides is provided with a groove or a spring bung.

Mit der erfindungsgemäßen Belagbühne können Belagbühnen ganz unterschiedlicher Breite aus den gleichen Grundbauelementen zusammengestellt werden; auf diese Weise kann die Fertigung und die Lagerhaltung auf wenige unterschiedliche Bauelemente beschränkt und dementsprechend vereinfacht werden.With the covering platform according to the invention, covering platforms of very different widths can be put together from the same basic structural elements; In this way, production and warehousing can be limited to a few different components and can be simplified accordingly.

Ein Hohlprofilstab 1 entsprechend Fig. 1 ist im Strangpreßverfahren hergestellt und von etwa rechteckigem Querschnitt. In eine erste Seitenfläche 1a ist eine Nut 11 eingetieft, so daß oben und unten je eine sich längs durchgehend erstreckende Leiste 12 bzw. 13 verbleibt. Die untere Leiste 13 ist massiv, jedoch ist, von der Nut 1a ausgehend, eine Sekundärnut 13a eingetieft, durch einen Steg 13b von der Seitenfläche 1a getrennt. Eine zweite Seitenfläche 1b ist - komplementär zu der Nut 11 - mit einem erhabenen Federspund 14 versehen, so daß oben und unten je eine sich längs durchgehend erstreckender Restraum 15 bzw. 16 verbleibt. In den unteren Restraum 16 ragt eine Stegleiste 14a, deren Querschnitt demjenigen der Sekundärnut 13a komplementär ist. Eine Deckfläche 1c und eine Bodenfläche 1d zwischen den Seitenflächen vervollständigen den Querschnitt des Hohlpofilstabes 1. Die Deckfläche 1c ist trittsicher strukturiertA hollow profile rod 1 corresponding to FIG. 1 is produced by the extrusion process and has an approximately rectangular cross section. A groove 11 is recessed into a first side surface 1 a, so that one bar 12 and 13, respectively, extending in a continuous manner remains above and below. The lower bar 13 is solid, but, starting from the groove 1a, a secondary groove 13a is recessed, separated from the side surface 1a by a web 13b. A second side surface 1b is - complementary to the groove 11 - provided with a raised spring bung 14, so that one each continuously along the top and bottom extending remaining space 15 or 16 remains. In the lower residual space 16, there is a web strip 14a, the cross section of which is complementary to that of the secondary groove 13a. A top surface 1c and a bottom surface 1d between the side surfaces complete the cross section of the hollow profile rod 1. The top surface 1c is structured to be non-slip

In der Fig. 5 ist zu erkennen, daß beliebig viele Hohlprofile 1 nebeneinander vorgesehen sein können, wobei die Nut 11 und der Federspund 14 ineinander geschoben ist, die Sekundärnut 13a die Stegleiste 14a aufnimmt und die oberen Resträume 15 jeweils mit einer oberen Leiste 12 ausgefüllt sind. Auf diese Weise sind die Hohlprofilstäbe 1 sicher miteinander verzargt.In Fig. 5 it can be seen that any number of hollow profiles 1 can be provided side by side, the groove 11 and the spring bung 14 is pushed into one another, the secondary groove 13a receives the web bar 14a and the upper remaining spaces 15 each filled with an upper bar 12 are. In this way, the hollow profile bars 1 are securely interlocked.

Ein weiterer, von demjenigen der Fig. 1 nur wenig abweichender Hohlprofilstab 1' ist in der Fig. 2 im Querschnitt dargestellt; er dient zur beiderseitigen Verbindung mit einem Federspund 14 und ist demzufolge an beiden Seitenflächen 1a' jeweils mit einer Nut 11' ausgerüstet, wobei die Nuten 11' achssymmetrisch ausgebildet sind, sich aber sonst von der Nut 11 der Fig. 1 nicht unterscheiden. Entsprechend schließen an der Deckfläche 1c' achssymmetrisch je eine Leiste 13' an; Resträume 15,16 sind hier nicht vorhanden. Die Fig. 4 und 5 machen deutlich, daß bei einer erfindungsgemäßen Belagbühne höchstens jeweils ein Hohlprofilstab 1' erforderlich ist, entweder (Fig. 4) zwischen zwei berandenden Hohlprofilstäben 1'' oder (Fig. 5) zwischen einem "inneren" Hohlprofilstab 1 und einem der berandenden Hohlprofilstäbe 1''.Another hollow profile rod 1 ', which differs only slightly from that of FIG. 1, is shown in cross section in FIG. 2; it is used for mutual connection with a spring bung 14 and is therefore equipped on both side surfaces 1a 'with a groove 11', the grooves 11 'being axially symmetrical, but otherwise not different from the groove 11 in FIG. 1. Correspondingly, a strip 13 'adjoins the cover surface 1c' in an axially symmetrical manner; Residual spaces 15, 16 are not available here. 4 and 5 make it clear that in a covering platform according to the invention at most one hollow profile rod 1 'is required, either (Fig. 4) between two bordering hollow profile rods 1' 'or (Fig. 5) between an "inner" hollow profile rod 1 and one of the bordering hollow profile bars 1 ''.

Die die erfindungsgemäße Belagbühne in Längsrichtung berandenden Hohlprofilstäbe 1'' sind - übereinandergelegt - in der Fig. 3 gezeigt. Sie unterscheiden sich von den Hohlprofilstäben 1 und 1' nur insofern, als an ihnen kein Federspund 14 vorgesehen ist und die zugehörige Seitenfläche 1b'' vielmehr eine glatte Wandfläche bildet. Beide Seitenflächen 1b'' sind demzufolge Bestandteile der Belagbühne, die im übrigen an ihren Querseiten von als U- oder L-Profil ausgebildeten Tragprofilen gebildet wird, an denen sämtliche Hohlprofilstäbe gelagert sind, am einfachsten, wenn sie auf dem (unteren) Gurt des jeweiligen Tragprofiles aufliegen und - zumindest die berandenden Hohlprofilstäbe 1'' - form- oder stoffschlüssig mit dem jeweiligen Tragprofil verbunden sind. Die Einzelheiten sind aber relativ beliebig ausführbar, stehen in keinem unmittelbaren Zusammenhang mit der Erfindung und sind in der Zeichnung weggelassen.The hollow profile bars 1 ″ bordering the covering platform according to the invention in the longitudinal direction are superimposed - Shown in Fig. 3. They differ from the hollow profile bars 1 and 1 'only in that no spring bung 14 is provided on them and the associated side surface 1b''rather forms a smooth wall surface. Both side surfaces 1b '' are consequently components of the covering platform, which is otherwise formed on its transverse sides by U-shaped or L-shaped supporting profiles on which all hollow profile bars are mounted, the simplest if they are on the (lower) belt of the respective Support profile rest and - at least the bordering hollow profile bars 1 '' - are positively or materially connected to the respective support profile. However, the details are relatively arbitrary, have no direct connection with the invention and are omitted from the drawing.

Die senkrechten glatten Seitenflächen 1b'' werden in der Deckfläche 1c'' und der Bodenfläche 1d'' von jeweils benachbarten Sicken 17 bzw. 18 begleitet, wobei die Sicken 17 der Deckfläche 1c'' erhaben aufgesetzt und die Sicken 18 in die Bodenflächen 1d'' eingetieft sind; sie sind gleichweit von der nächsten Seitenfläche 1b'' entfernt und so profiliert, daß sie bei gestapelten Hohlprofilstäben 1'' und entsprechend auch bei gestapelten Belagbühnen so ineinander geraten, daß die Deck- und Bodenflächen 1c,1c',1c'' und 1d,1d',1d'' flächig berührend aufeinanderliegen. Dabei wird gleichzeitig gesichert, daß quergerichtete Bewegungen der gestapelten Hohlprofilstäbe bzw. Belagbühnen nicht mehr stattfinden können.The vertical smooth side surfaces 1b '' are accompanied in the top surface 1c '' and the bottom surface 1d '' by respectively adjacent beads 17 and 18, the beads 17 of the top surface 1c '' being raised and the beads 18 in the bottom surfaces 1d ''areengrossed; they are equidistant from the next side surface 1b '' and profiled so that they come into contact with one another in the case of stacked hollow profile bars 1 '' and accordingly also in the case of stacked covering platforms in such a way that the top and bottom surfaces 1c, 1c ', 1c''and 1d, 1d ', 1d''lie flat on top of each other. At the same time, it is ensured that transverse movements of the stacked hollow profile bars or covering platforms can no longer take place.
