Abstract

The pneumatically inflated load bearing building element is arch-shaped, and is made of coated or rubberised woven material, with or without an inner tube, and with its ends held in place by abutments. Two lengthways aligned fishplates (2, 3) fitted with eye loops, parallel to each other but with a significant interval between them, are firmly joined to the underside of the element. These fishplates are drawn towards each other by zig-zag draw-cords (4, 5), so as to have the effect of increasing the fishplate edges interval from the centre of the arch (1) to the abutments (6, 7). The fishplates may be stitched onto the outer sheath (1) of the load bearing element, and they may be cross braced by the draw-cords.

Description

Die Erfindung betrifft ein bogenförmiges pneumatisches Tragelement aus beschichtetem oder gummiertem Gewebe mit oder ohne Innenschlauch, welches an »einen Enden mittels Widerlagern fixiert ist.The invention relates to an arcuate pneumatic support element made of coated or rubberized Fabric with or without an inner tube, which is »fixed at one end by means of abutments.

Es ist bekannt, beidendig verschlossene, schlauchartige pneumatische Bauelemente an ihren Enden mittels Widerlagern so zu fixieren, daß das unter Druck stehende Bauelement sich zu einem torbogenähnlichen Gebilde verformt. Mehrere derartiger Tragelemente lassen sich parallel und in Abständen zueinander aufbauen und anschließend mit einer Dachhaut überziehen. It is known to use hose-like pneumatic components closed at both ends at their ends To fix abutments so that the pressurized component becomes an archway-like Deformed structure. Several such support elements can be parallel and spaced from one another build up and then cover with a roof membrane.

Egal, ob man ein bereits unter Druck stehendes schlauchförmiges Bauelement zu einem derartigen bogenförmigen Tragelement formen will oder ob man die Enden des noch nicht aufgeblasenen Schlauches fixiert und erst dann durch Druckaufgabe das bogenförmige Tragelement erzeugt, man erhält stets auf der Bogeninnenseite starke Knicke, die eine lokale Überbeanspruchung des beschichteten oder gummierten Gewebes oder gar des Innenschlauches bewirken können. Meist entsteht sogar nur ein einzigen dafür aber besonders spitzwinkliger Knick, der verhindert, daß das Tragelement die gewünschte Bogenform annimmtRegardless of whether a tubular component that is already under pressure is added to such a Want to shape arched support element or whether you want to remove the ends of the tube that has not yet been inflated fixed and only then created the arched support element by printing, you always get on the The inside of the arch has strong kinks that result in a local overstressing of the coated or rubberized Can cause tissue or even the inner tube. Usually only one is created for it, however particularly acute-angled kink that prevents the support element from assuming the desired arch shape

Die der Erfindung zugrundeliegende Aufgabe besteht darin, starke Knicke bei bogenförmigen pneumatischen Tragelementen zu vermeiden.The object of the invention is to eliminate strong kinks in arcuate pneumatic To avoid supporting elements.

Das bogenförmige pneumatische Tragelement der eingangs genannten Art ist erfindungsgemäß dadurch gekennzeichnet, daß an der Bogenunterseite zwei in Längsrichtung verlaufende, mit ösen versehene Laschen parallel und in deutlichem Abstand voneinander mit dem Tragelement fest verbunden sind und daß die Laschen durch Zurrleinen so gegeneinandergezogen sind, daß der Abstand der Laschenränder von derThe arcuate pneumatic support element of the type mentioned at the beginning is characterized according to the invention characterized in that on the underside of the sheet there are two longitudinal tabs provided with eyelets are firmly connected in parallel and at a considerable distance from each other with the support element and that the Tabs are pulled against each other by lashing lines so that the distance between the tab edges from the

Bogenmitte zu den Widerlagern hin zunimmtThe center of the arch increases towards the abutments

Durch die erfindungsgemäßc Ausgestaltung des -pneumatischen Tragelements wird eine praktisch knickfreie Formung des schlauchförmigen Bauelements zu einem Bogen ermöglicht Die durch die Zurrieinen entstehenden Einschnürungen des aufgeblasenen Tragelements können dabei zwar auch als Mikro-Knickstellen betrachtet werden; derartig stark ausgeprägte Knickstellen, wie sie bei zum Stand der Technik ίο gehörenden Tragelementen auftreten, werden jedoch vermieden.The inventive design of the -pneumatic support element is a practically kink-free shaping of the tubular component into a bow The constrictions of the inflated support element caused by the lashing ropes can also be viewed as micro-kinks; so strongly pronounced However, kinks, as they occur in the case of supporting elements belonging to the state of the art, are avoided.

Aus Gründen der erhöhten Festigkeit sind die Laschen auf die Außenhülle des Tragelements zweckmäßigerweise aufgenähtFor reasons of increased strength, the tabs on the outer shell of the support element are expedient sewn on

is Bevorzugt wird ein bogenförmiges pneumatisches Tragelement, bei dem die Laschen durch Zurrleinnen kreuzverspannt sind.An arcuate pneumatic is preferred Support element in which the straps are cross-braced by lashing strips.

Die Erfindung wird anhand der Zeichnung näher erläutert Darin istThe invention is explained in more detail with reference to the drawing

ίο F i g. t die Draufsicht auf eine noch nicht aufgeblasene Außenhülle, wobei das bevorzugte Verzurrungsschema nur im Prinzip dargestellt ist,ίο F i g. t the top view of an uninflated one Outer shell, whereby the preferred lashing scheme is only shown in principle,

F i g. 2 die Unterseite eines erfindungsgemäß ausgebildeten Tragelements im aufgeblasenen Zustand und
J5 F i g. 3 die Seitenansicht des in F i g. 2 dargestellten Tragelements.
F i g. 2 shows the underside of a support element designed according to the invention in the inflated state and
J5 F i g. 3 shows the side view of the in FIG. 2 supporting element shown.

Wie in F i g. 1 zu erkennen ist, sind auf der Außenhülle 1 zwei Laschen 2 und 3 befestigt, vorzugsweise aufgenäht. Die Laschen 2 und 3 verlaufen dabei ebenso wie ihre Nähte 2' bzw. 3' im wesentlichen parallel zueinander und in Längsrichtung der Außenhülle. Die Laschen 2 und 3 haben im nicht verzurrten Zustand einen gleich großen Abstand voneinander.As in Fig. 1 can be seen, two tabs 2 and 3 are attached to the outer shell 1, preferably sewn on. The flaps 2 and 3, like their seams 2 ' and 3', run essentially parallel to one another and in the longitudinal direction of the outer shell. The straps 2 and 3 have the same distance from one another when they are not lashed down.

Mittels einer oder mehrerer Zurrleinen — im Ausführungsbeispiel mittels zweier Zurrleinen 4 und 5, deren bevorzugte kreuzförmige Anordnung in F i g. 1 dargestellt ist — lassen sich die Abstände zwischen den beiden Laschen 2 und 3 derart verringern, daß der Abstand in der Bogenmitte Γ ein Minimum beträgt und zu den Enden hin zunimmt (vgl. F i g. 2).By means of one or more lashing lines - in the exemplary embodiment by means of two lashing lines 4 and 5, the preferred cross-shaped arrangement of which is shown in FIG. 1 shown is - the distances between the two tabs 2 and 3 can be reduced so that the Distance in the middle of the arc Γ is a minimum and increases towards the ends (cf. FIG. 2).

Bläst man ein derart verzurrtes Tragelement, bei dem der Abstand der Laschen von der Bogenmitte zu den Enden hin in abnehmendem Maße vftrringert worden ist, auf, nachdem es auf den Widerlagern 6 und 7 fixiert ist, so entsteht eine knickfreie, bogenförmige Wölbung des Tragelements.If you blow such a lashed support element, in which the distance between the tabs from the center of the sheet to the The ends have been reduced to a decreasing extent, after it has been fixed on the abutments 6 and 7 is, the result is a kink-free, arched curvature of the support element.

Durch die Wahl der ösenabstände, der Laschenabstände und des Verzurrungsschemas lassen sich die Abstände der Mikro-Knickstellen variieren. Bei hoher Anzahl von Mikro-Knickstellen geht die Wölbung in eine Bogenform über.By choosing the spacing between the eyes and the tabs and the lashing scheme, the distances between the micro-kinks can be varied. At high With a number of micro-kinks, the curve changes into an arch shape.

Es ist nicht nötig, Laschenlänge L und Schlauchlänge gleich zu wählen. Vielmehr ist es möglich, nur Teil-Abschnitte der Außenhülle t mit Laschen und Zurrleinen zu versehen, wie aus F i g. 3 ersichtlich.It is not necessary to choose the same bracket length L and hose length. Rather, it is possible to provide only partial sections of the outer shell t with straps and lashing lines, as shown in FIG. 3 can be seen.

Auf diese Weise können zahlreiche Bogenformen entstehen.Numerous arch shapes can be created in this way.

Bevorzugtes Material für Innenschlauch, Außenhülle, Laschen und Zurrleinen sind hochfeste Hochpolymere, wie Polyamide und Polyester, insbesondere aber hochfestes PolyäthylenterephthalatThe preferred material for the inner tube, outer cover, straps and lashing lines are high-strength high-strength polymers, such as polyamides and polyesters, but especially high-strength polyethylene terephthalate
