Abstract

The invention relates to a framework, in particular for erecting stands at fairs, essentially consisting of supporting columns and transverse struts. A framework of this type is to be erectable simply, rapidly and inexpensively. For this purpose, the supporting columns (12) are formed from a pumped-up gastight and flexible envelope. Transverse struts (14) are articulated in each case to the upper end of the supporting columns. As a result, a stable framework consisting of pneumatically mountable elements is provided, which can be mounted in a short time with a small attendance crew and is therefore very inexpensive. <IMAGE>

Description

Die Erfindung betrifft ein Tragwerk, insbesondere zum Errichten von Messeständen, das im wesentlichen aus Stützsäulen und Quer­verstrebungen besteht.The invention relates to a supporting structure, in particular for erecting exhibition stands, which essentially consists of supporting columns and cross struts.

Messehallen sind in viele einzelne gleichförmige Flächensegmente unterteilt, welche je nach Bedarf an die entsprechenden Ausstel­ler vermietet werden. Für jeden Aussteller werden individuell Messestände in den jeweils angemieteten Hallenbereichen er­stellt. Dazu werden Tragwerke verwendet, die an die individuel­len Bedürfnisse des vom Aussteller errichteten Messestandes ange­paßt werden können. Als Tragwerke kommen dabei bislang Metall- oder Leichtmetallkonstruktionen zum Einsatz, welche aus senk­recht stehenden Säulenelementen und entsprechenden Querverstre­bungen bestehen. Stützen und Querverstrebungen werden in der Re­gel durch Schraubverbindungen miteinander zu einem Tragwerk ver­bunden. Die Errichtung derartiger Tragwerke ist aufwendig und dadurch sehr kostspielig.Exhibition halls are divided into many individual, uniform area segments, which can be rented to the relevant exhibitors as required. Exhibition stands are created for each exhibitor in the rented hall areas. For this purpose, structures are used that can be adapted to the individual needs of the exhibition stand set up by the exhibitor. So far, metal or light metal constructions have been used as supporting structures, which consist of vertically standing column elements and corresponding cross struts. Columns and cross struts are usually connected to each other by a screw connection to form a supporting structure. The construction of such structures is complex and therefore very expensive.

Es stellt sich daher die Aufgabe, Tragwerke zu entwickeln, die einfach und kostengünstig zu errichten bzw. abzubauen sind.It is therefore the task to develop structures that are easy and inexpensive to erect or dismantle.

Erfindungsgemäß wird diese Aufgabe von einem gattungsgemäßen Tragwerk mit den Merkmalen des kennzeichnenden Teils des An­ spruchs 1 gelöst. Dabei werden die Stützsäulen des Tragwerks durch aufgepumpte gasdichte und flexible Hüllen gebildet, wobei die Querverstrebungen jeweils an dem oberen Ende der Stützsäulen angelenkt sind. Durch Vorsehen der aufpumpbaren Hüllen kann das gesamte Tragwerk pneumatisch aufgerichtet werden. Das erfindungs­gemäße Tragwerk kann dadurch von wenigen Monteuren schnell und kostengünstig aufgerichtet werden.According to the invention, this object is achieved by a generic structure with the features of the characterizing part of the spell 1 solved. The support columns of the structure are formed by inflated, gas-tight and flexible shells, the cross struts being articulated at the upper end of the support columns. By providing the inflatable sleeves, the entire structure can be erected pneumatically. The supporting structure according to the invention can thus be erected quickly and inexpensively by a few fitters.

Die jeweiligen Querverstrebungen zwischen den einzelnen Stützsäu­len können auch je aus einer aufgepumpten gasdichten und flexi­blen Hülle bestehen, wobei sich die Querverstrebungen bogenför­mig zwischen den Anlenkpunkten der Stützsäulen erstrecken. Die aufpumpbaren gasdichten und flexiblen Hüllen der Stützsäulen und gegebenenfalls der Querverstrebungen können in vorteilhafter Wei­se aus bewehrter Polyethylenfolie bestehen. Derartige Folien wei­sen hinreichende Festigkeiten auf, um einem Innendruck von mehre­ren bar standzuhalten. Andererseits lassen sie sich nach Ablas­sen der Druckluft in einem verhältnismäßig kleinem Volumen zusam­menlegen, so daß sie für den Transport in verhältnismäßig kleine Transportkisten hinein zusammenfalt- bzw. legbar sind.The respective cross struts between the individual support columns can also each consist of an inflated, gas-tight and flexible shell, the cross struts extending in an arc between the articulation points of the support columns. The inflatable gas-tight and flexible sleeves of the support columns and, if applicable, the cross struts can advantageously consist of reinforced polyethylene film. Such films have sufficient strengths to withstand an internal pressure of several bar. On the other hand, after the compressed air has been discharged, they can be folded together in a relatively small volume, so that they can be folded or placed for transport into relatively small transport boxes.

Gegebenenfalls können die oberen Enden der Stützsäulen durch Säu­lenkapitell gebildet werden, an die jeweils die Querverstrebun­gen angelenkt werden können. Die Säulenkapitell können zusammen mit den zusammenlegbaren Stützsäulen und jeweils mindestens einer Hülle für die mindestens eine vorzusehende Querverstrebung in einer Transportkiste untergebracht werden.If necessary, the upper ends of the support columns can be formed by column capitals to which the cross struts can be articulated. The column capital can be accommodated in a transport box together with the collapsible support columns and in each case at least one cover for the at least one cross strut to be provided.

Alternativ zu den aus den flexiblen Schlauchhüllen bestehenden Querverstrebungen können auch starre Streben vorgesehen werden. Das Tragwerk kann zwischen den Stützsäulen beispielsweise durch Trennwände ausgekleidet werden. Diese können aus an sich bekann­ten aus Karton bestehenden Raumelementen bestehen.As an alternative to the cross struts consisting of the flexible tubular sleeves, rigid struts can also be provided. The structure can be lined between the support columns, for example by partitions. These can consist of space elements known from cardboard.

Die besonderen Vorteile des erfindungsgemäßen Tragwerks zeigen sich in dem Verfahren zum Errichten des Tragwerks gemäß Anspruch 8 und der darauf zurückbezogenen Ansprüche. Demnach werden die die Stützsäulen bildenden Hüllen vor dem Aufpumpen an vorbezeich­neten Punkten des Hallenbodens - entsprechend der voreingeteil­ten Segmente - angeordnet und mit dem Boden verankert. An­schließend werden die Hüllen mit mindestens einer Druckluftquel­le verbunden und aufgepumpt. Schließlich werden die errichteten Stützsäulen mittels der Querverstrebungen miteinander verbunden.The particular advantages of the structure according to the invention can be seen in the method for erecting the structure according to claim 8 and the claims relating to it. Accordingly, the envelopes forming the support columns are arranged at the aforementioned points on the floor of the hall, in accordance with the pre-divided segments, and anchored to the floor before being inflated. The casings are then connected to at least one compressed air source and inflated. Finally, the support columns are connected to each other by means of the cross struts.

Auf die aufgepumpten Stützsäulen können Säulenkapitell aufge­bracht werden, zwischen denen die später die Querverstrebungen bildenden Hüllen verlaufen, wonach diese ebenfalls mit minde­stens einer Druckluftquelle verbunden und aufgepumpt werden.Column capital can be applied to the inflated support columns, between which the shells later forming the cross struts run, after which these are also connected and pumped up with at least one compressed air source.

Besonders vorteilhaft ist es, wenn die auf den vorbezeichneten Punkten des Hallenbodens angeordneten Hüllen der Stützsäulen fest mit den Säulenkapitelln verbunden sind, welche jeweils min­destens eine später eine Querverstrebung bildende Hülle tragen, wobei diese vor dem Aufpumpen derart miteinander verbunden wer­den, daß die später die Querverstrebung bildende Hülle mit dem Säulenkapitell der benachbarten Stützsäule verbunden wird und wobei danach über mindestens eine zentrale Druckluftquelle das gesamte Tragwerk aufgepumpt wird. Dabei wird die Druckluft über die Querverstrebungen und entsprechende Kanäle bzw. Durchbrüche in den Säulenkapitelln den einzelnen Stützsäulen zugeleitet.It is particularly advantageous if the shells of the support columns arranged on the above-mentioned points of the hall floor are firmly connected to the column capitals, each of which carries at least one envelope which later forms a cross brace, these being connected to one another before inflation so that the later is the cross brace forming shell is connected to the column capital of the adjacent support column and the entire structure is then inflated via at least one central compressed air source. The compressed air is fed to the individual support columns via the cross struts and corresponding channels or openings in the column capitals.

Die sich hieraus beim Errichten des Tragwerks ergebende Erleich­terung ist offensichtlich, da die miteinander zu verbindenden Stützsäulen vor Aufpumpen des pneumatischen Tragwerks, d.h. am Boden, miteinander verbunden werden und erst anschließend pneuma­tisch aufgerichtet werden.The resulting relief when erecting the structure is obvious because the supporting columns to be connected to each other before inflating the pneumatic structure, i.e. on the ground, are connected to each other and only then are pneumatically erected.

Ein so errichtetes Tragwerk kann anschließend durch geeignete Verkleidungselemente unterteilt werden und entsprechende am Trag­werk anzubringende Elemente, wie beispielsweise eine Bedachung, Schilder oder andere Elemente beispielsweise eines Messestandes aufnehmen.A structure constructed in this way can then be replaced by suitable Cladding elements are subdivided and accommodate corresponding elements to be attached to the structure, such as a roof, signs or other elements, for example of a trade fair stand.

In Fig. 1 ist ein Tragwerk 10 dargestellt, das vier quadratische Segmente eines Messehallenbodens überspannt. Dazu sind Stützsäu­len 12 auf den jeweiligen Eckpunkten 22, 24, 26, 28, 30, 32, 34, 36 und 38 der quadratischen Segemente angeordnet und verankert. Die Stützsäulen 12 bestehen aus aufgepumpten gasdichten und fle­xiblen Hüllen, beispielsweise Hüllen aus bewehrter Polyethylen­folie. Diese sind beispielsweise mit ca. zwei bar aufgepumpt. Am oberen Ende der Stützsäulen sind Säulenkapitell 18 aufgebracht.1 shows a supporting structure 10 which spans four square segments of an exhibition hall floor. For this purpose, support columns 12 are arranged and anchored on the respective corner points 22, 24, 26, 28, 30, 32, 34, 36 and 38 of the square segments. The support columns 12 consist of inflated, gas-tight and flexible casings, for example casings made of reinforced polyethylene film. For example, these are inflated to approximately two bar. Column capitals 18 are applied to the upper end of the support columns.

An die Säulenkapitell 18 sind Querverstrebungen angelenkt, die gemäß diesem Ausführungsbeispiel ebenfalls aus aufgepumpten gas­dichten und flexiblen schlauchförmigen Hüllen bestehen. Die Quer­verstrebungen erstrecken sich jeweils bogenförmig zwischen den Anlenkpunkten benachbarter Stützsäulen. Sie dienen dazu, auf das Tragwerk wirkende Querkräfte aufzunehmen.Cross struts are articulated to the column capital 18, which, according to this exemplary embodiment, likewise consist of inflated, gas-tight and flexible tubular casings. The cross struts each extend in an arc between the articulation points of adjacent support columns. They serve to absorb transverse forces acting on the structure.

Alternativ zu den aus flexiblen Hüllen bestehenden aufgepumpten Querverstrebungen sind auch Querverstrebungen aus Leichtmetall denkbar, die mit entsprechenden Anlenkpunkten der Säulenkapitell 18 verbindbar sind.As an alternative to the inflated cross struts consisting of flexible sleeves, cross struts made of light metal are also conceivable, which can be connected to corresponding articulation points of the column chapter 18.

Zwischen den Stützsäulen 12, können, wie aus den Fig. 1 bzw. 2 ersichtlich, Trennwände oder sonstige Auskleidungen, wie z. B. Türelemente, bildende Elemente 20 bzw. 22 angeordnet werden. Die Elemente 20, 22 können beispielsweise aus gefaltetem Karton be­stehen und sind als solche bereits bekannt. Wie insbesondere aus der Fig. 2 ersichtlich, können an die Querverstrebungen 14 bei­spielsweise Hinweisschilder oder sonstige für einen Messestand notwendigen Teile gehängt werden.Between the support columns 12, as can be seen from FIGS. 1 and 2, partitions or other linings, such as. B. door elements, forming elements 20 and 22 may be arranged. The elements 20, 22 can, for example, consist of folded cardboard and are already known as such. As can be seen in particular from FIG. 2, for example, information signs or other parts necessary for a trade fair stand can be hung on the cross struts 14.

Anhand der Fig. 3a-3c kann das Verfahren zum Errichten des Trag­werks erläutert werden.3a-3c, the method for erecting the structure can be explained.

In Fig. 3a sind die noch nicht aufgepumpten Hüllen für die Stütz­säulen 12 auf die vorbezeichneten Punkte 22, 24 und 26 des Hal­lenbodens gelegt und in üblicher Art und Weise, beispielsweise durch Nägel, mit dem Boden verankert (nicht dargestellt). Dabei können die Hüllen auch in nicht dargestellten Transportkisten auf die entsprechenden Punkte 22, 24 und 26 gestellt werden, wo­bei die Transportkisten, mit denen die Hüllen fest verbunden sind, mit dem Boden verankert werden.In Fig. 3a the not yet inflated sleeves for the support columns 12 are placed on the aforementioned points 22, 24 and 26 of the hall floor and anchored to the floor in a conventional manner, for example by nails (not shown). The sleeves can also be placed on the corresponding points 22, 24 and 26 in transport boxes (not shown), the transport boxes with which the sleeves are firmly connected being anchored to the floor.

Anschließend werden die die Stützsäulen bildenden Hüllen mit einer Druckluftquelle 40 verbunden und pneumatisch aufgerichtet. Dies kann in vorteilhafter Weise durch Parallel-Schaltung der Druckluftzuführung gleichzeitig erfolgen. Gemäß dem in Fig. 3b dargestellten Ausführungsbeispiel werden die ebenfalls aus auf­pumpbaren Hüllen bestehenden Querverstrebungen 14, die zuvor mit den Säulenkapitelln 18 verbunden worden sind ebenfalls an eine Druckluftquelle angeschlossen und aufgepumpt und anschließend auf die Säulen 12 aufgesetzt.Then the envelopes forming the support pillars are included a compressed air source 40 connected and pneumatically erected. This can advantageously be done simultaneously by connecting the compressed air supply in parallel. According to the exemplary embodiment shown in FIG. 3 b, the cross struts 14, which likewise consist of inflatable sleeves and which have previously been connected to the column capitals 18, are also connected to a compressed air source and pumped up and then placed on the columns 12.

Fig. 3c zeigt das teilweise aufgerichtete Tragwerk, wobei in der rechten Hälfte dieser Figur eine alternative Aufrichtmöglichkeit für die Querstrebe 14 gezeigt ist, die erst dann mit Druckluft aufgepumpt wird, wenn die Säulenkapitell 18 schon auf den Stütz­säulen 12 aufgebracht sind.3c shows the partially erected structure, an alternative erection possibility for the cross strut 14 being shown in the right half of this figure, which is only inflated with compressed air when the column capitals 18 have already been applied to the support columns 12.

Alternativ zu dem zuvor erläuterten Aufrichtverfahren des Trag­werks können die später die Stützsäulen 12 bildenden Hüllen vor dem Aufpumpen fest mit den Säulenkapitelln 18 und untereinander über die noch nicht aufgepumpten Hüllen für die Querverstrebun­gen 14 verbunden sein, so daß sämtliche Stützsäulen und Querver­strebungen eines Tragwerkes miteinander ein kommunizierendes Hüllensystem bilden. Hierdurch wird ein besonders einfaches Auf­richtverfahren erzielt, da das gesamte Tragwerk auf dem Boden vormontiert und anschließend durch Anschließen mindestens einer Druckluftquelle gemeinsam pneumatisch aufgerichtet werden kann.As an alternative to the erection method of the structure explained above, the sleeves which later form the support columns 12 can be firmly connected to the column chapters 18 and to one another via the sleeves for the cross struts 14 which have not yet been inflated, so that all the support pillars and cross struts of a structure are communicating with one another Form the envelope system. This results in a particularly simple erection process, since the entire structure can be preassembled on the floor and then pneumatically erected by connecting at least one compressed air source.

Durch das neu an die Hand gegebene pneumatische Tragwerk wird insbesondere das Verfahren zum Errichten von beispielsweise Messeständen oder dgl. vereinfacht und verkürzt, wodurch eine beträchtliche Kostenersparnis erzielt wird.The new pneumatic support structure, in particular, simplifies and shortens the process for setting up trade fair stands or the like, for example, which results in considerable cost savings.
