Abstract

The invention relates to a push rod (3) that absorbs pressure forces of a pneumatic element that comprises a hollow body (3) filled with a pressurized gas. Said push rod comprises a groove (8) with a substantially circular widened section (10) and a neck (9). A pocket (6) which is fastened to the hollow body (2) across its entire length can be drawn into said groove (8) before the hollow body (2) is impinged upon with the pressurized gas. After drawing, a clamping element (11) with a substantially circular cross-section is drawn into the part of the pocket (6) lying in the groove (8). Once the hollow body (2) is impinged upon with pressurized gas, the circumferential tension of the hollow body (2) extends across the clamped part of the pocket (6).

Description

Druckstab für pneumatische BauelementePressure rod for pneumatic components
Die vorliegende Erfindung bezieht sich auf einen Druckstab, also ein Element zur Aufnahme der Druckkräfte bei einem pneumatischen Bauelement, und eine Vorrichtung zu seiner Befestigung nach dem Oberbegriff des Patentanspruches 1. Solche Druckstäbe sind bekannt und beschrieben beispielsweise in der Europäischen Patentanmeldung 01 903 559.1 des gleichen Erfinders.The present invention relates to a pressure rod, that is to say an element for absorbing the pressure forces in a pneumatic component, and a device for fastening it according to the preamble of patent claim 1. Such pressure rods are known and described, for example, in European patent application 01 903 559.1 of the same inventor.
Im genannten Dokument ist der Druckstab aus praktischen Erwägungen mehrteilig ausgeführt, wobei die einzelnen Teile oder Abschnitte in aller Regel nach- bzw. hintereinander in geeignet geformten Taschen am pneumatischen Bauelement eingescho- ben werden. Da diese einzelnen Abschnitte nur Druckkräfte aufnehmen und übertragen, ist es völlig ausreichend, diese einfach stumpf stossend aneinander zu reihen.In the document mentioned, the pressure rod is made up of several parts for practical reasons, the individual parts or sections generally being inserted one after the other or one behind the other in suitably shaped pockets on the pneumatic component. Since these individual sections only absorb and transmit pressure forces, it is entirely sufficient to simply butt them together.
Die von den Druckstäben aufzunehmenden Kräfte können jedoch beträchtlich werden. Dies verlangt, dass die Druckkräfte über möglichst die ganze Querschnittsfläche von einem Abschnitt des Druckstabes auf den anderen übertragen werden. Dies ist jedoch nur dann der Fall, wenn die genannten Taschen sehr genau gefertigt sind, und beim Einschieben der Stabteile oder - abschnitte äusserst sorgfältig vorgegangen wird. Das wiederum verteuert die Herstellung der pneumatischen Bauelemente und verlangsamt den Aufbau vor Ort. Ferner ist es möglich, dass trotz grosser Genauigkeit beim Fertigen und Sorgfalt beim Aufbau, sich durch beispielsweise windinduzierte Bewegungen der pneumatischen Bauelemente mit der Zeit gegenseitige Ver- Schiebungen der Abschnitte ergeben, die der Qualität der Bauelemente abträglich sind. Zudem sind die Druckstäbe grundsätzlich in den genannten Taschen eingelegt. Fixationspunkte für technische Anlagen und Geräte sind in der Regel mit Verletzung der Taschen verbunden und mit zusätzlichem Aufwand verbunden.However, the forces to be absorbed by the compression rods can be considerable. This requires that the compressive forces be transmitted over the entire cross-sectional area from one section of the compression rod to the other. However, this is only the case if the pockets mentioned are made very precisely and the insertion of the rod parts or sections is carried out with extreme care. This in turn increases the cost of manufacturing the pneumatic components and slows down the assembly on site. Furthermore, it is possible that despite great accuracy in the manufacture and care in the assembly, wind-induced movements of the pneumatic components, for example, result in mutual displacements of the sections over time, which are detrimental to the quality of the components. In addition, the pressure rods are always inserted in the pockets mentioned. Fixation points for technical systems and devices are usually associated with injury to the pockets and associated with additional effort.
Die Aufgabe der vorliegenden Erfindung ist die Schaffung eines Druckstabes, der die genannten Nachteile nicht aufweist und überdies die Möglichkeit bietet, zugängliche Befestigungspunkte für Anlagen und Apparate der Energie- und Haustechnik zu schaffen.The object of the present invention is to provide a pressure rod which does not have the disadvantages mentioned and also offers the possibility of creating accessible fastening points for systems and apparatus for energy and building technology.

Fig. la, b beziehen sich auf den Stand der Technik. Fig. la ist ein pneumatisches Bauelement 1 in Seitenansicht und be- steht aus einem hier zylindrischen Hohlkörper 2, auf welchen ein Druckstab 3 aufgesetzt ist. An den Enden des Druckstabes 3 ist dieser mit zwei Zugbändern 4 fest verbunden, welche in gegenläufigem Schraubungssinne um den Hohlkörper gespannt sind und dort straff anliegen. In der Terminologie der Baustatik sind diese Befestigungsstellen der Zugbänder 4 Knoten 5 genannt. Gemäss der Technik wird der Druckstab 3 in Taschen 6 eingeschoben, welche am Hohlkörper durch Schweissen, Kleben oder Nähen befestigt sind.Fig. La, b relate to the prior art. FIG. 1 a is a pneumatic component 1 in a side view and consists of a hollow body 2 which is cylindrical here and on which a pressure rod 3 is placed. At the ends of the compression rod 3, it is firmly connected with two tension bands 4, which are tensioned in opposite screwing directions around the hollow body and are tight there. In the terminology of structural engineering, these fastening points of the drawstrings are called 4 nodes 5. According to the technology, the pressure rod 3 is inserted into pockets 6 which are fastened to the hollow body by welding, gluing or sewing.
Der Hohlkörper 2 weist zwei Kappen 18 auf, die ihn nach aussei! abschliessen, und besteht vorzugsweise aus einem wenig dehnbaren textilen Gewebe und ist entweder luftdicht ausgeführt -beispielsweise mit einer PVC-Beschichtung - oder ist nur zugfeste aber nicht luftdichte Hülle für einen eingelegten Gasschlauch aus einem elastischen Kunststoff. Soll der Hohlkörper 2 luftdicht sein, so sind die Nähte der Taschen 6 nach dem Nähen abzudichten. Fig. lb zeigt einen Querschnitt AA durch das pneumatische Bauelement 1 in etwas grösserem Massstab. Hier ist noch ersichtlich, dass die Zugbänder 4 allenfalls in Laschen 7 geführt werden können, um deren Lage im schlaffen Zustande des Bauelementes 1 zu fixieren. Fig. 2a, b nun zeigt ein erstes Ausführungsbeispiel des er- findungsgemässen Druckstabes 3 in einem Querschnitt, in Fig. 2a allein, in Fig. 2b zusammen mit dem noch nicht mit Druckgas beaufschlagten Hohlkörper 2. Der Druckstab 3 weist über seine ganze Länge eine Nut 8 auf, welche - im Querschnitt - einen engen Hals 9 und eine etwa kreisförmige Ausweitung 10 aufweist. Das Material der Tasche 6 kann in die noch leere Nut 8 eingestülpt werden; um es darin zu fixieren, wird ein über die ganze Länge des Druckstabes 3 sich erstreckendes Klemmelement 11 eingezogen. Dieses kann aus einem runden Stabe aus beispielsweise Aluminium oder Kunststoff, oder auch aus einer textilen Rundschnur bestehen. Die Tasche 6 ist so auf dem Material des Hohlkörpers 2 befestigt, dass dieses im schlaffen Zustande des Hohlköpers 2 so locker liegt, dass die Zugspannung in der Hülle des Hohlkörpers 2 im Bereiche des Druckstabes 3 über das Material der Tasche β läuft. Wiederum gibt es hier zwei Varianten: Die Hülle des Hohlkörpers 2 ist luftdicht ausgeführt, oder in die Hülle des Hohlkörpers wird ein aus einem elastischen Kunststoff bestehender Gasschlauch 12 eingelegt. Durch das Klemmelement 11 werden die Teile des Druckstabes 3 dauernd zum Fluchten gebracht.The hollow body 2 has two caps 18 which move it outwards! seal, and preferably consists of a little stretchy textile fabric and is either airtight - for example with a PVC coating - or is only a tensile but not airtight cover for an inserted gas hose made of an elastic plastic. If the hollow body 2 is to be airtight, the seams of the pockets 6 are to be sealed after sewing. Fig. Lb shows a cross section AA through the pneumatic component 1 on a somewhat larger scale. It can also be seen here that the drawstrings 4 can at most be guided in tabs 7 in order to fix their position in the slack state of the component 1. 2a, b now shows a first exemplary embodiment of the pressure rod 3 according to the invention in a cross section, in FIG. 2a alone, in FIG. 2b together with the hollow body 2 which has not yet been pressurized with pressure gas. The pressure rod 3 has a length over its entire length Groove 8, which - in cross section - has a narrow neck 9 and an approximately circular extension 10. The material of the pocket 6 can be slipped into the still empty groove 8; in order to fix it therein, a clamping element 11 extending over the entire length of the pressure rod 3 is drawn in. This can consist of a round rod made of aluminum or plastic, for example, or of a textile round cord. The pocket 6 is fastened to the material of the hollow body 2 in such a way that when the hollow body 2 is slack, it lies so loosely that the tensile stress in the shell of the hollow body 2 runs in the area of the compression rod 3 over the material of the pocket β. Again, there are two variants: the shell of the hollow body 2 is made airtight, or a gas hose 12 made of an elastic plastic is inserted into the shell of the hollow body. The parts of the pressure rod 3 are continuously brought into alignment by the clamping element 11.
In Fig. 3 ist ein zweites Ausführungsbeispiel des erfindungs- gemässen Druckstabes 3 dargestellt, zusammen mit Teilen der Hohlkörper 2. Der Druckstab 3 ist hier so ausgeführt, dass er zwei Nuten 8 aufweist, welche einander spiegelbildlich gegenüberliegen. Mit dem Druckstab 3 gemäss Fig. 3 können zwei pneumatische Bauelemente 1 gemäss Fig. 1 gekoppelt werden. Wird das pneumatische Bauelement 1 jedoch so ausgeführt, dass es längs zweier, azimutal um 180° versetzter, Mantellinien je einen Druckstab 3 aufweist - je mit zwei Zugbändern 4 versehen, so lassen sich mit dem Druckstab 3 gemäss Fig. 3 beliebig viele pneumatische Bauteile 1 aneinanderreihen, beispielsweise um eine Dachfläche zu bilden. In Fig. 4 ist eine Weiterbildung des Druckstabes 3 gemäss Fig. 3 dargestellt. Der Druckstab 3 weist ebenfalls zwei Nuten 8 auf. Sein Querschnitt ist jedoch grösser, als jener des Ausführungsbeispiels gemäss Fig. 3. In diesem vergrösserten Querschnitt sind beispielsweise zwei längs des Druckstabes 3 verlaufende Bohrungen 13 angebracht. Diese sind vorgesehen, um Fluide, beispielsweise Wasser und/oder Druckluft, zu führen. Im dargestellten Querschnitt sind zwei Schnellverschlüsse 14 dargestellt, die auf Bohrungen 15 aufgesetzt sind, welche quer zu den längs verlaufenden Bohrungen 13 angebracht sind, und es ermöglichen, Wasser- und Druckluftverbraucher, die unter einem oben erwähnten Dach vorgesehen sind, zu versorgen. Selbstverständlich sind die genannten Schnellverschlüsse 14 so codiert, dass sie nur entweder für Wasser oder für Druckluft verwendbar sind, wie es dem Stande der Technik entspricht.3 shows a second exemplary embodiment of the pressure rod 3 according to the invention, together with parts of the hollow body 2. The pressure rod 3 is designed here in such a way that it has two grooves 8, which are opposite one another in mirror image. 3, two pneumatic components 1 according to FIG. 1 can be coupled. However, if the pneumatic component 1 is designed such that it has a compression rod 3 along two, azimuthally offset, 180 °, generatrices, each provided with two tension bands 4, then the compression rod 3 according to FIG. 3 can be used for any number of pneumatic components 1 string together, for example to form a roof surface. 4 shows a further development of the pressure rod 3 according to FIG. 3. The pressure rod 3 also has two grooves 8. However, its cross section is larger than that of the exemplary embodiment according to FIG. 3. In this enlarged cross section, for example, two bores 13 running along the pressure rod 3 are made. These are provided to carry fluids, for example water and / or compressed air. In the cross section shown, two quick-release fasteners 14 are shown, which are placed on bores 15, which are arranged transversely to the longitudinal bores 13, and make it possible to supply water and compressed air consumers, which are provided under a roof mentioned above. Of course, the quick-release fasteners 14 mentioned are coded such that they can only be used either for water or for compressed air, as is the case in the prior art.
Werden mehrere Abschnitte von Druckstäben 3 stumpf gestossen, so befinden sich zwischen den einzelnen Abschnitten Verbindungselemente ebenfalls nach dem Schnellverschluss-Prinzip, wie in Fig. 5 in einer Seitenansicht dargestellt ist. Hier ist zwischen den Schnellverschlüssen 14 beispielsweise ein Zwischenstück 16 angeordnet, welches einerseits auf Längsbelastung elastisch federnd reagiert, anderseits flexibel ist auf Biegung, so dass die Schnellverschlüsse 14 statisch gese- hen unbestimmt sind, und keine nennenswerten Biege- und Druckkräfte darüber abgeleitet werden. Selbstverständlich sind Wasser und Druckluft nur im Sinne von nicht beschränkenden Beispielen gedacht. Allgemeiner kann von Versorgungslei- tungen gesprochen werden, die durch die längs verlaufenden Bohrungen 13 realisiert werden. Ferner kann der Druckstab 3, entweder alternativ oder kumulativ zu den genannten Bohrungen 13 noch Stromschienen bekannter Bauart tragen. Selbstverständlich sind in dieser Art und Weise auch Nachrichten- und Datenleitungen - beispielsweise über Koaxialkabel in den Druckstäben 3 - integrierbar. Damit kann ein provisorisches oder auf Dauer angelegtes mit den genannten pneumatischen Bauelementen 1 errichtetes Gebäude, oder auch nur eine entsprechende Überdachung, ohne das Verlegen von Leitungen mit allen notwendigen Zuleitungen ausgerüstet und versehen werden.If several sections of pressure rods 3 are butted, connecting elements are also located between the individual sections according to the quick-release principle, as shown in a side view in FIG. 5. Here, for example, an intermediate piece 16 is arranged between the quick-release fasteners 14, which on the one hand reacts elastically resiliently to longitudinal loading, and on the other hand is flexible to bend, so that the quick-release fasteners 14 are statically secured. hen are undetermined, and no significant bending and compressive forces are derived. Of course, water and compressed air are only intended in the sense of non-limiting examples. More generally, one can speak of supply lines that are realized by the longitudinally running bores 13. Furthermore, the pressure rod 3, either alternatively or cumulatively to the bores 13 mentioned, can also carry busbars of a known type. Of course, message and data lines can also be integrated in this way - for example via coaxial cables in the pressure bars 3. A provisional or permanent building constructed with the pneumatic components 1 mentioned, or even just a corresponding roof, can thus be equipped and provided with all the necessary supply lines without the laying of lines.
Als weiteres Ausführungsbeispiel des erfindungsgemässen Druckstabes 3 ist ein solcher zur Verbindung von vier pneumatischen Bauelementen 1 in Fig. 6 schematisch dargestellt. Er trägt, entsprechend seiner Bestimmung, im Querschnitt vier Arme 17, an deren Enden die beschriebenen Nuten 8 angeordnet sind. Selbstverständlich lassen sich einer oder mehrere Arme 17 wiederum zur Aufnahme von Versorgungsleitungen gemäss dem zu Fig. 6 Gesagten gestalten und ausrüsten. Anstelle von vier Armen 17 kann der Druckstab 3 selbstverständlich auch eine andere Anzahl von Armen 17 aufweisen, wie z.B. drei oder sechs. Zusätzlich können die daran befestigten pneumatischen Bauelemente 1 mit Druckstäben 3 gemäss Fig. 3 ausgerüstet und damit untereinander verbunden sein. Es ist vorteilhaft, die Druckstäbe 3 aus extrudierten Aluminiumprofilen zusammenzusetzen, da dies einerseits kostengünstig, anderseits mit grosser Gestaltungsfreiheit erfolgen kann. Ebenso können die vorzusehenden Druckkräfte mit den notwendigen Querschnittsflächen und -formen in Einklang ge- bracht werden.As a further exemplary embodiment of the pressure rod 3 according to the invention, one for the connection of four pneumatic components 1 is shown schematically in FIG. 6. According to its purpose, it carries four arms 17 in cross section, at the ends of which the grooves 8 described are arranged. Of course, one or more arms 17 can in turn be designed and equipped for receiving supply lines in accordance with what has been said for FIG. 6. Instead of four arms 17, the push rod 3 can of course also have a different number of arms 17, e.g. three or six. In addition, the pneumatic components 1 attached to it can be equipped with pressure rods 3 according to FIG. 3 and thus connected to one another. It is advantageous to assemble the pressure rods 3 from extruded aluminum profiles, since on the one hand this can be done inexpensively and on the other hand with great freedom of design. Likewise, the pressure forces to be provided can be brought into line with the necessary cross-sectional areas and shapes.
Damit werden andere Materialien, wie extrudierbare Kunststoff-Kompositwerkstoffe keineswegs verworfen, gilt es doch für jeden Anwendungszweck von pneumatischen Bauelementen die hinsichtlich Aufgabe, Gestaltung und Kosten die optimale Lösung zu finden. This means that other materials, such as extrudable plastic composite materials, are in no way discarded, since the same applies to every application of pneumatic components to find the optimal solution in terms of task, design and costs.
