- the invention is therefore based on the object of designing a covering platform of the type specified in the introduction with simple means in a reliable manner and designing it in such a way that additional connecting elements between the hollow profile bars are 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.

Abstract
Platform flooring for scaffolding should be designed so that it is as light as possible, can be produced from only a few components, is effective in use and can be securely assembled. In addition, its width should be variable. The invention calls for the platform flooring to be made of extruded-drawn hollow sections (1) which are connected to each other along the edges by a groove-and-tongue joint (11, 14). Also included in the system are hollow-section edging sections (1', 1') which make a specially designed support section unnecessary.
Description
Belagbühne für Gerüste Covering platform for scaffolding
Beschreibung:Description:
Die Erfindung betrifft eine Belagbühne für Gerüste, insbe- sondere 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 construction 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 AI bereits be¬ kannt. Die Hohlprofilstäbe sind dort in ganzer Länge ausge¬ spart 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 German Offenlegungsschrift 43 23 381 A1. The hollow profile bars are cut out there over their entire length and are otherwise shaped such that they can be nested into one another by means of these cutouts and a single profile is sufficient to be able to put together a complete covering 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 nö¬ tige Formsteifigkeit beim Zusammenbau dadurch hergestellt wird, daß die benachbarten Hohlprofilstäbe miteinander ver¬ nietet werden, weil anders wegen der durchgehenden Ausspa¬ rungen 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 Lageεiche-
rung 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 stiffness during assembly is produced by riveting the adjacent hollow profile bars together, because otherwise the wall thicknesses of the profiles involved would have had to be increased significantly because of the continuous recesses. The beads are directed inward throughout to enable suitable locking of adjacent hollow profile bars so that they stacking of several platforms can not contribute. 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 einfa¬ chen Mitteln betriebssicher zu gestalten und so auszubil¬ den, 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 is therefore based on the object of designing a covering platform of the type specified in the introduction with simple means in a reliable manner and designing it in such a way that additional connecting elements between the hollow profile bars are 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 ausge¬ bildet sind, deren aneinanderstoßende, den Längsseiten des Tragrahmens parallele Seitenflächen auf der einen Seite des jeweiligen Hohlprofilstabes eine zu der Seitenfläche paral¬ lele, durchgehende Nut und auf dessen anderer Seite einen zu der Nut komplementär geformten Federspund aufweisen, wo¬ bei zwei benachbarte Hohlprofilstäbe miteinander durch die Nut des einen und den darin plazierten Federspund des ande¬ ren 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 Trag¬ rahmens bildenden Seite lediglich mit einer vorzugsweise glatten Seitenfläche versehen ist und nur an der jeweils anderen, einem benachbarten Hohlprofilstab zugewandten Sei- tenflache mit einer Nut oder einem Federspund ausgestattet ist und daß schließlich die Querseiten des Tragrah enε je¬ weils aus einem Tragprofil bestehen, auf dem der Belag auf-
liegt 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 formed as closed extruded profiles, the abutting side faces of which are 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 one on the other side have a spring bung complementarily shaped to the groove, whereby two adjacent hollow profile bars can be mutually tied together through the groove of one and the spring bung of the other hollow profile bar placed therein, so that the longitudinal sides of the support frame are also each formed by a similar tileable hollow profile bar, which, however, is only provided with a preferably smooth side surface on one side forming the outer boundary of the supporting frame and only with a groove or a spring bung a on the other side surface facing an adjacent hollow profile rod and that finally the transverse sides of the supporting frame each consist of a supporting profile on which the covering lies and that serves to attach the covering 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 sta¬ bile begehbare Fläche aus sehr leichten Strangpreßteilen zusammengestellt werden kann. Die Teile müssen weder ver¬ schraubt noch vernietet werden und können in beliebiger An¬ zahl aneinander gefügt werden; eine enge Teilung gewährlei- stet auf diese Weise auch bei Leichtbauprofilen durch die große Anzahl der das Widerstandsmoment bestimmenden senk¬ rechten Stege der einzelnen Hohlprofilstäbe eine hohe Trag¬ fähigkeit 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 by means of the tongue and groove joint 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 which determine the section modulus.
Eine praktisch spielfreie Verbindung benachbarter Hohlpro- filstäbe erfolgt beispielsweise dadurch, daß an dem Feders¬ pund eine parallele, senkrechte Stegleiste einstückig ange¬ formt 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 Querrich¬ tung der Belagbühne.A practically backlash-free connection of adjacent hollow profile bars is achieved, for example, by integrally integrally molding a parallel, vertical web strip on the spring tongue, 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 einschlie߬ lich der Bereiche von Nut und Federspund. Eine solche Auε- bildung ist technologisch günstig, weil bei ihrer Herstel¬ lung Wärmespannungen möglichst vermieden werden, die bei größeren Wanddickensprüngen auftreten können.The hollow profile bars can essentially be of approximately the same wall thickness on all sides, that is to say including the areas of the tongue and groove bung. Such an embodiment is technologically favorable because during its manufacture thermal stresses are avoided as possible, which can occur with larger changes in wall thickness.
Besonders praktisch ist es, wenn die berandenden, dieIt is particularly practical when the bordering, the
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 Sei¬ tenfläche 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 Voraus¬ setzung dafür geschaffen ist, daß die Sicken so bemessen werden können, daß sie bei übereinander gelegten Belagbüh¬ nen mit aneinander anliegenden Belägen ineinander geraten und als Stapelhilfe eine gegenseitige Querverschiebung der Belagbühnen verhindern.Longitudinal sides of the support frame forming hollow profile bars on their top surface serving as a tread surface and on the opposite surface area of the same area with each At least one bead is provided, which is adjacent and parallel to the smooth side surface, in particular if the bead is raised in the top surface and that is recessed in the bottom surface, because in this way - apart from the improved dimensional stability - the prerequisite for this It is created that the beads can be dimensioned such that they come into contact with one another with covering platforms placed one on top of the other with covering layers lying against one another and prevent a mutual transverse displacement of the covering platforms as a stacking aid.
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 Endbe¬ reichen zumindest teilweise an dem Tragprofil befestigt sein können. Es kann bereits ausreichend sein, die beran¬ denden Hohlprofile an den Tragprofilen zu befestigen und die übrigen nur aufzulegen, insbesondere bei der Verwendung von U-Profilen.The covering platform is completed in a suitable manner if the support 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 with their end portions rich can be at least partially attached to the support profile. It may already be sufficient to attach the bordering hollow profiles to the supporting profiles and only to lay the others on, in particular 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 ei- ner 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 is provided on both sides with a groove or a spring bung.
Mit der erfindungsgemäßen Belagbühne können Belagbühnen ganz unterschiedlicher Breite aus den gleichen Grund¬ bauelementen zusammengestellt werden; auf diese Weise kann die Fertigung und die Lagerhaltung auf wenige un- terschiedliche Bauelemente beschränkt und dementsprechend vereinfacht werden.
Die Erfindung wird nachstehend an Hand der Zeichnung an ei¬ nem Ausführungsbeispiel näher erläutert. Es zeigenWith the covering platform according to the invention, covering platforms of very different widths can be put together from the same basic components; In this way, production and warehousing can be limited to a few different components and can be simplified accordingly. The invention is explained in more detail below with the aid of an exemplary embodiment. Show it

Ein Hohlprofilstab 1 entsprechend Fig. 1 ist im Strangpre߬ verfahren hergestellt und von etwa rechteckigem Quer¬ schnitt. In eine erste Seitenfläche la ist eine Nut 11 ein¬ getieft, so daß oben und unten je eine sich längs durchge¬ hend erstreckende Leiste 12 bzw. 13 verbleibt. Die untere Leiste 13 ist massiv, jedoch ist, von der Nut la ausgehend, eine Sekundärnut 13a eingetieft, durch einen Steg 13b von der Seitenfläche la getrennt. Eine zweite Seitenfläche lb ist - komplementär zu der Nut 11 - mit einem erhabenen Fe¬ derspund 14 versehen, so daß oben und unten je eine sich längs durchgehend erstreckender Reεtraum 15 bzw. 16 ver¬ bleibt. In den unteren Restraum 16 ragt eine Stegleiste 14a, deren Querschnitt demjenigen der Sekundärnut 13a kom¬ plementär ist. Eine Deckfläche lc und eine Bodenfläche ld zwischen den Seitenflächen vervollständigen den Querschnitt des Hohlpofilstabes 1. Die Deckfläche lc ist trittsicher strukturiertA hollow profile rod 1 corresponding to FIG. 1 is produced in the extrusion process and has an approximately rectangular cross section. A groove 11 is recessed into a first side surface 1 a, so that a strip 12 and 13, which extends longitudinally continuously, remains at the top and bottom. The lower bar 13 is solid, but, starting from the groove la, a secondary groove 13a is recessed, separated from the side surface la by a web 13b. A second side surface 1b is - complementary to the groove 11 - provided with a raised spring bung 14, so that a longitudinally extending rear space 15 or 16 remains at the top and bottom. 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 Hohlpro¬ file 1 nebeneinander vorgesehen sein können, wobei die Nut
11 und der Federspund 14 ineinander geschoben ist, die Se¬ kundärnut 13a die Stegleiεte 14a aufnimmt und die oberen Reεträume 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 next to one another, 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 rear spaces 15 are each filled with an upper bar 12. In this way, the hollow profile bars 1 are securely interlocked.
Ein weiterer, von demjenigen der Fig. 1 nur wenig abwei¬ chender Hohlprofilstab 1' ist in der Fig. 2 im Querschnitt dargestellt; er dient zur beiderseitigen Verbindung mit ei¬ nem Federspund 14 und iεt demzufolge an beiden Seitenflä- chen la' jeweilε mit einer Nut 11' ausgerüstet, wobei die Nuten 11' achsεymmetriεch auεgebildet sind, sich aber sonst von der Nut 11 der Fig. 1 nicht unterscheiden. Entsprechend schließen an der Deckfläche lc' achssymmetriεch je eine Leiste 13' an; Resträume 15,16 sind hier nicht vorhanden. Die Fig. 4 und 5 machen deutlich, daß bei einer erfindungε- gemäßen Belagbühne höchεtenε jeweilε ein Hohlprofilstab 1' erforderlich ist, entweder (Fig. 4) zwischen zwei beran¬ denden Hohlprofilstäben 1" oder (Fig. 5) zwiεchen einem "inneren" Hohlprofilstab 1 und einem der berandenden Hohl- profilstäbe 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 accordingly equipped with a groove 11 'on both side surfaces 1 a', the grooves 11 'being axially symmetrical, but otherwise not being different from the groove 11 in FIG. 1 differentiate. Correspondingly, a strip 13 'adjoins the cover surface 1c' axisymmetrically; Residual spaces 15, 16 are not available here. 4 and 5 make it clear that in the case of a covering platform according to the invention, a hollow profile bar 1 'is required at the most, either (FIG. 4) between two adjacent hollow profile bars 1 "or (FIG. 5) between an" inner " Hollow section bar 1 and one of the bordering hollow section bars 1 ".

Beide Sei¬ tenflächen lb" sind demzufolge Bestandteile der Belagbühne, die im übrigen an ihren Querseiten von als U- oder L-Profil ausgebildeten Tragprofilen gebildet wird, an denen sämtli- ehe Hohlprofilstäbe gelagert sind, am einfachsten, wenn εie auf dem (unteren) Gurt deε jeweiligen Tragprofileε auflie¬ gen und - zu indeεt die berandenden Hohlprofilεtäbe 1" -

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 formed on its transverse sides by support profiles designed as U or L profiles, on which all hollow profile bars are mounted, the simplest if they are on the (lower) The belt of the respective support profile rests and - to the independent the bordering hollow profile bars 1 "- positively or materially connected to the respective support profile. are.
