Träger für den Gerüst- oder Gerippebau
Die Erfindung betrifft einen Träger für den Gerüst-oder Gerippebau, vorzugsweise in Metall, bei welchem zwei oder mehr profilierte Teile bzw. Schienen, vorzugsweise annähernd mit U-Profil, parallel und in einem bestimmten Abstand voneinander derart angeordnet werden, dass ihre Flanken bzw. Flansche einander zugekehrt sind, zwischen ihnen jedoch ein Zwischenraum bleibt, und dass die profilierten Teile bzw.
Schienen durch auf ihrer ganzen Länge in bestimmten Abständen paarweise angeordnete und an den Profilflanken bzw. -flanschen angreifende Querstützen bzw. Verbindungsschellen in ihrer gegenseitigen Lage
EMI1.1
schen und die Querstützen bzw. Verbindungsschellen zu durchbohren und mittels durch die Bohrungen hindurchgeführter Schraubbolzen zu verschrauben. Das Zusammenfügen benötigt somit sehr viel Zeit, da jede Verbindungsschelle mittels je einer Schraube an dem ihr benachbarten Teil bzw. der ihr benachbarten
Schiene festgelegt ist, somit pro Verbindungsschelle zwei Schrauben angezogen werden müssen, um den Abstand zwischen den Schienen festzulegen. Des weiteren wird durch das Anbringen der Bohrung sowohl der Querschnitt der Schienen geschwächt als auch der Querschnitt der Verbindungsschelle an zwei Stellen ver- mieden.
Diese Nachteile können jedoch vermieden werden, wenn gemäss der Erfindung jeweils einesder für die profilierten Teile bzw. Schienen ein Q. 1erstLitzen - bzw. Verbindungsschellenpaar bildenden Elemente an der Aussenseite der Flanken bzw. Flansche und das andere Element an deren Innenseite angreift und dass an den profilierten Teilen bzw. Schienen Längsrippen oder Längsnuten vorgesehen sind, die gleichzeitig Versteifungen für die profilierten Teile bzw. Schienen darstellen und Halterungen für die Querstützen-bzw. Verbindungsschellenpaare bilden, deren Flächen entsprechend den Langsrippen bzw. Längsnuten geformt sind, so dass sie den Abstand zwischen den profilierten Teilen bzw. Schienen festlegen.
Durch die erfindungsgemässe Massnahme kann die Verbindung zwischen der Verbindungsschelle und den beiden ihr benachbarten Schienen durch Eingriff der Schiene in die Verbindungsschelle überraschend schnell hergestellt werden, ohne dass die Schiene durchbohrt werden müsste. Eine Querschnittsverminderung der Schieneistsomitvermiedenund ausserdem bilden die zur Verbindung vorgesehenen Langsrippen oder Längsnuten Versteitungen tür die profillerten 1 elle bzw. schienen.
Es ist auch möglich, dass die ein zusammengehöriges Paar bildenden Elemente nur an die Aussenflä- chender Profilflanken von zwei nebeneinander oder einander gegenüberliegenden Profilteilen angelegt werden. Jedes Verbindungsschellenpaar wird durch mindestens einen durch beide Teile hindurchgehenden Bolzen oder eine Schraube zusammengehalten, durch deren Festziehen die Elemente an den Profilflanken festgelegt werden. Die erfindungsgemässen Träger bieten weiters noch den Vorteil, dass sie, bedingt durch den zwischen den einzelnen Profilteilen vorhandenen Zwischenraum, die rasche und bequeme Befestigung von Ansatzteilen jeder Art ermöglichen, wie z. B. Halter oder Stützen für Bretter, Trag- oder Ablagegestelle od. dgl.
Die Befestigungsplatten für diese Ansatzteile können des weiteren so ausgebildet werden, dass sie zugleich eines der ein Verbindungsschellenpaar bildenden Elemente darstellen.
Obwohl für die Schienen bevorzugt ein U-Profil gewählt wird, ist es gleicherweise möglich, hiefür auch Winkel profile oder andere Querschnittsformen heranzuziehen. Auch können sowohl Steg als auch Flanken der verwendeten U- oder Winkelprotile Illcht nur flach, sondern auch gewolbt oder mit Falzen, Sicken, Vorsprüngen oder Einkerbungen in den verschiedensten Ausführungen und Formen versehen sein.
Die Erfindung wird an Hand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert.
<Desc/Clms Page number 2>
Es zeigen die Fig. 1- 8 in schematischer Form verschiedene Querschnitte von Trägern für den Gerüst-oder Gerippebau, die aus mittels Querstützen zusammengehaltenen Profilteilen bestehen, die Fig. 9 - 12 verschiedene Möglichkeiten für die Anordnung der Befestigungsflansche und Fig. 13 einen Längsschnitt durch einen Teil eines Gerüstträgers, an dem ein Ansatzstück befestigt ist.
Fig. 1 zeigt die einfachste mögliche Ausführungsform eines Trägers für den Gerüstbau entsprechend dem Erfindungsgedanken. Der Träger besteht in diesem Falle aus zwei Teilen 1, l'mit U-Profil, die in
EMI2.1
chenden Ausführungsmöglichkeiten herleiten.
So bilden beispielsweise die Flanken 2, 2'der U-förmig profilierten Teile 1, l'der Anordnung nach Fig. 2 dachförmig vorspringende Rippen, während bei der Anordnung gemäss Fig. 3 die entsprechenden Flanken 2, 2'hohlkehlenartig nach innen verformt sind.
Beider Anordnung nach Fig. 4 bilden die Flanken 2, 2'der U-Profile in ähnlicher Weise, wieinFig. 2, vorspringende Rippen, doch sind ihre Stege nicht flach, sondern gewölbt. Die Verformung der Stege kann so weit getrieben werden, dass ein Querschnitt entsteht, wie er in Fig. 5 gezeigt ist. In diesem Falle ist der profilierte Teil l, l'dann ein Winkelprofil, dessen beide Stege und dessen Flanken 2, 2'jeweils rechtwinkelig abgebogen sind.
Die bisher beschriebenen Träger für Gerüstbau waren jeweils nur aus zwei einander zugekehrt angeordneten profiliertenTeilen zusammengesetzt, die lediglich bei den verschiedenen Ausführungsformen verschiedenen Querschnitt aufweisen. Wie die Fig. 6 - 8 zeigen, können sie aber auch aus mehr als zwei Pro-
EMI2.2
oder im Sechseck angeordnet sind und jeweils untereinander Zwischenräume aufweisen; die Flanken 2, 2' sind jeweils nach innen gerichtet und können bei U-Profilen rechtwinkelig an die Stege anschliessen oder unter einem beliebigen Winkel gegen diese geneigt sein.
Demgemäss können die Träger für Gerüstbau in der in Fig. 6 dargestellten Weise aus vier U-Profilteilen 1, 1', 1", 13 zusammengesetzt werden. Diese vier Profilteile können ebene bzw. gerade Stege aufweisen, oder in der in Fig. 7 gezeigten Weise beispielsweise eine längs der Achse verlaufende dreieckartige Sicke 5 enthalten. Der in Fig. 8 dargestellte Träger besteht aus sechs U- Profilteilen 1, 1', 1", 13, 14,
EMI2.3
Die in den Fig. 1 - 8 gezeigten verschiedenartigen Profilzusammenstellungen werden in ihrer jeweiligen Anordnung durch die Querträger- oder Verbindungsschellenpaare 3, 3'festgelegt, die in den Fig. 9 bis 12 noch etwas genauer dargestellt werden.
In den Fig. 9-11 umfassen die Elemente 6, 6'eines jeden Flanschenpaares beidseitig die sich jeweils gegenüberstehenden Flanken 2, 2'der Profilteile 1, 1'. Durch die Schrauben oder Bolzen 7 werden
EMI2.4
setzungen die Schraubenbolzen in einem Vierkant 8 endigen, der das Anziehen der Schraube mittels eines entsprechenden Schlüssels ermöglicht, dieses Anziehen der Schraube kann gegebenenfalls dank dem freien Zwischenraum zwischen den Proìilteilen von der gegenüberliegeuluen öene ues lragers dus vorgenommen werden, In den meisten Fällen greifen die Auflageflächen der Elemente 6, 6'über eine gewisse Länge in Längsnutenoder Rippen ein, die in den Flanken der Profilteile vorgesehen werden können und legen auf diese Weise den zwischen den einzelnen Profilteilen eines Trägers vorbestimmten Abstand fest.
Fig. 12 zeigt den Zusammenbau von zwei gegeneinander gerichteten U-Profilen, die mittels eines Paares von Verbindungsschellen und durch eine gemeinsame durchgehende Schraube 9 verbunden sind, wobei die Elemente 6 des Verbindungsschellenpaares lediglich an den Aussenseiten der Flanken 2, 2'anreiz fen. Diese Art der Montage ist einfacher als die zuvor beschriebenen, ist jedoch bevorzugt nur anwendbar, wenn über die Gesamtlänge der Träger ein vollkommen freier Abstand der Profilteile nicht unbedingt erforderlich ist.
Fig. 13 zeigt den Längsschnitt durch einen Träger für Gerüstbau in seiner Anwendung alsGerüststange für ein Gerüst beliebiger Art. Ein Abstell- oder Arbeitstisch bzw. -brett 10 ist daran befestigt, wobei die (lotrecht angebrachte) Grundplatte dieses konsolartigen Tisches oder Brettes zugleich eines der beiden das Verbindungsflanschpaar bildenden Elemente 6 darstellt.
Es ist leicht zu erkennen, dass ausgehend von dem oben dargelegten Grundgedanken eine fast unbegrenzte Vielzahl von Ausführungsmöglichkeiten für den Erfindungsgedanken besteht und die gezeigten Beispiele dessen andersartige Anwendung in keiner Weise einschränken.

Beams for scaffolding or framework construction
The invention relates to a support for scaffolding or framework construction, preferably in metal, in which two or more profiled parts or rails, preferably approximately with a U-profile, are arranged parallel and at a certain distance from one another in such a way that their flanks or The flanges are facing each other, but there is a gap between them, and that the profiled parts or
Rails in their mutual position by means of cross supports or connecting clamps arranged in pairs over their entire length at certain intervals and engaging the profile flanks or flanges
EMI1.1
and to drill through the cross supports or connection clamps and to screw them by means of screw bolts passed through the holes. The assembly thus requires a great deal of time, since each connecting clamp is attached to the part or the adjacent part by means of a screw
Rail is set, so two screws must be tightened per connection clamp to determine the distance between the rails. Furthermore, by making the bore, both the cross-section of the rails is weakened and the cross-section of the connecting clip is avoided at two points.
However, these disadvantages can be avoided if, according to the invention, one of the elements forming a pair of first strands or connecting clamps for the profiled parts or rails acts on the outside of the flanks and the other element acts on their inside and that on the profiled parts or rails longitudinal ribs or longitudinal grooves are provided, which at the same time represent stiffeners for the profiled parts or rails and brackets for the cross support or. Form connecting clamp pairs, the surfaces of which are shaped according to the longitudinal ribs or longitudinal grooves, so that they define the distance between the profiled parts or rails.
As a result of the measure according to the invention, the connection between the connecting clamp and the two rails adjacent to it can be established surprisingly quickly by engaging the rail in the connecting clamp without having to drill through the rail. A reduction in cross-section of the rail is thus avoided and, in addition, the longitudinal ribs or longitudinal grooves provided for connection form reinforcements for the profiled elbows or rails.
It is also possible that the elements forming a pair that belong together are only placed on the outer surfaces of the profile flanks of two profile parts that are next to one another or opposite one another. Each pair of connecting clamps is held together by at least one bolt or screw that goes through both parts, and when these are tightened, the elements are fixed to the profile flanks. The carriers according to the invention also offer the advantage that, due to the space between the individual profile parts, they enable quick and easy attachment of attachment parts of any kind, such as. B. Holders or supports for boards, support or storage racks or the like.
The fastening plates for these attachment parts can also be designed in such a way that they also represent one of the elements forming a pair of connecting clamps.
Although a U-profile is preferably chosen for the rails, it is equally possible to use angle profiles or other cross-sectional shapes for this. Both the web and the flanks of the U-shaped or angled profile Illcht used can also be flat, but also curved or provided with folds, beads, projections or notches in a wide variety of designs and shapes.
The invention is explained in more detail with reference to the exemplary embodiments shown in the drawing.
<Desc / Clms Page number 2>
1-8 show in schematic form different cross-sections of girders for scaffolding or framework construction, which consist of profile parts held together by means of cross supports, FIGS. 9-12 different possibilities for the arrangement of the fastening flanges and FIG. 13 a longitudinal section through part of a scaffolding beam to which an extension piece is attached.
Fig. 1 shows the simplest possible embodiment of a carrier for scaffolding according to the inventive concept. The carrier in this case consists of two parts 1, l 'with a U-profile, which in
EMI2.1
derive the appropriate design options.
For example, the flanks 2, 2 'of the U-shaped profiled parts 1, 1' of the arrangement according to FIG. 2 form roof-shaped projecting ribs, while in the arrangement according to FIG. 3 the corresponding flanks 2, 2 'are deformed inwardly in the manner of a fillet.
In the arrangement according to FIG. 4, the flanks 2, 2 'of the U-profiles form in a manner similar to that in FIG. 2, protruding ribs, but their webs are not flat, but arched. The deformation of the webs can be driven so far that a cross-section as shown in FIG. 5 is produced. In this case the profiled part 1, 1 'is then an angle profile, the two webs of which and the flanks 2, 2' of which are each bent at right angles.
The supports for scaffolding described so far were each composed of only two profiled parts arranged facing each other, which only have different cross-sections in the various embodiments. As shown in FIGS. 6-8, they can also consist of more than two pro-
EMI2.2
or are arranged in a hexagon and each have spaces between them; the flanks 2, 2 'are each directed inwards and, in the case of U-profiles, can connect at right angles to the webs or be inclined towards them at any desired angle.
Accordingly, the supports for scaffolding can be composed of four U-profile parts 1, 1 ', 1 ", 13 in the manner shown in FIG. 6. These four profile parts can have flat or straight webs, or in the one shown in FIG Way, for example, contain a triangular bead 5 running along the axis. The carrier shown in Fig. 8 consists of six U-profile parts 1, 1 ', 1 ", 13, 14,
EMI2.3
The various types of profile combinations shown in FIGS. 1-8 are fixed in their respective arrangement by the cross member or connecting clamp pairs 3, 3 ′, which are shown in more detail in FIGS. 9 to 12.
In FIGS. 9-11, the elements 6, 6 ′ of each pair of flanges comprise the opposing flanks 2, 2 ′ of the profile parts 1, 1 ′ on both sides. Through the screws or bolts 7 are
EMI2.4
the screw bolts end in a square 8, which enables the screw to be tightened using an appropriate wrench.This tightening of the screw can be carried out if necessary thanks to the free space between the profile parts of the opposite opening of the elements 6, 6 'over a certain length in longitudinal grooves or ribs, which can be provided in the flanks of the profile parts and in this way determine the predetermined distance between the individual profile parts of a carrier.
Fig. 12 shows the assembly of two mutually directed U-profiles, which are connected by means of a pair of connecting clamps and a common continuous screw 9, the elements 6 of the connecting clamp pair only stimulating on the outside of the flanks 2, 2 '. This type of assembly is simpler than that described above, but is preferably only applicable if a completely free spacing of the profile parts is not absolutely necessary over the entire length of the carrier.
Fig. 13 shows the longitudinal section through a support for scaffolding in its application as a scaffolding rod for a scaffolding of any type represents the two elements 6 forming the pair of connecting flanges.
It is easy to see that, based on the basic idea set out above, there is an almost unlimited number of possible embodiments for the idea of the invention and the examples shown do not in any way restrict its different application.
