Like this Fig. 21 It can be seen is located next to an example caused by a natural disaster breakthrough of the protective device 800, a lattice structure 820, which is longer than the breakthrough and thus is supported on the areas of the protection device 800, which adjoin the breakthrough.
- the lattice structure is a sturdy construction that can serve, for example, as a foundation for sand accumulation or sandbag accumulation so that the breakthrough can be relatively quickly sealed without the risk of flushing away the sand or sandbags.
- Fig. 22 shows the arrangement of a lattice support work 820 on the land side of a protective device 800, which is arranged by means of fixing devices 830, which are fixedly arranged at certain intervals on the protective device 800, as shown Fig. 22 , bottom illustration.

- Such a system makes it possible, if necessary, for example, before a hurricane hits the coast, to mount the lattice structures 820 at the endangered areas by means of the fixing points 830 in order to protect the coast accordingly.
- the lattice structures 820 can be transported in the unexpanded state quickly to the desired location, there spread and then mounted.
- it is of course also possible to mount the lattice structures 820 first and then spread open. Due to the detachable connection between the lattice structures 820 and the fixing points 830, the lattice structures 820 can then be removed and stowed again.
- Fig. 24 shows a ship 850, which is designed with two expandable lattice structures 860.
- the lattice structures are pivoted away from the hull of the ship 850 by means of pivotable rods 870, as illustrated for the lattice support 860 shown above. When pivoting or after pivoting the lattice structure 860 is spread.
- the lattice support structure 860 shown below is located tightly against the hull of the ship 860 in a corresponding recess, so that no increased flow resistance arises.
- the lattice structure 860 can for example serve as a shield for warships against projectiles or as a lifeboat or as a stabilizer, if in the hull of the ship 850 water has penetrated or if high waves require stabilization of the ship 850.
- the lattice structures can have air-filled chambers which can be designed in such a way that that the lattice support 860 itself is buoyant or ensures a sufficiently high buoyancy that a sinking of the ship 850 or its capsizing can be prevented at high seas.

- the distance of the lattice structures 860 from the hull of the ship 850 or from the other lattice structure 860 can be arbitrarily set.
- Fig. 26 makes clear that the lattice structure can also be used as a rescue bridge to another ship or for loading or unloading or as approach or exit of a ship.
Abstract
Description
Die Erfindung betrifft ein Gittertragwerk mit gelenkig miteinander verbundenen Gitterstäben.The invention relates to a lattice structure with articulated interconnected bars.
Gittertragwerke werden beispielsweise bei Konstruktionen eingesetzt, die nur für eine vorübergehende Zeit aufgebaut und zum Transport wieder abgebaut werden müssen. Denkbar ist es ebenfalls, Gittertragwerke bereit zu stellen, die permanent an Ort und Stelle verbleiben und beispielsweise als Stützkonstruktionen für Gebäude etc. dienen. In beiden Fällen ist es von Nachteil, dass die einzelnen Elemente der Gittertragwerke sehr viel Platz benötigen, da sie große Querschnitte aufweisen. Dieser Nachteil ergibt sich nicht nur beim Transport, sondern selbstverständlich auch bei der Lagerung oder sonstigen Bevorratung derartiger Gittertragwerke. Aufgabe der Erfindung ist es, eine Gitterstruktur für Gittertragwerke zu schaffen, die in unterschiedliche Positionen bewegbar ist und in wenigstens einer Position nur vergleichsweise wenig Raum benötigt.Lattice structures are used, for example, in structures that must be built only for a temporary period and dismantled for transport again. It is also conceivable to provide lattice structures which remain permanently in place and serve, for example, as support structures for buildings, etc. In both cases, it is disadvantageous that the individual elements of the lattice structures need a lot of space, since they have large cross-sections. This disadvantage arises not only during transport, but of course also during storage or other storage of such lattice structures. The object of the invention is to provide a lattice structure for lattice structures, which is movable in different positions and requires only comparatively little space in at least one position.
Diese Aufgabe wird durch ein Gittertragwerk mit den Merkmalen des Anspruchs 1 gelöst. Danach ist vorgesehen, dass das Gittertragwerk sich wiederholende, aufeinanderfolgende Strukturen aufweist, die in eine pyramidenartige oder pyramidenstumpfartige Struktur aufspreizbar sind, wobei die Spitze einer der Strukturen mit der Grundfläche der benachbarten Struktur in Verbindung steht oder ein Teil der Grundfläche der benachbarten Struktur bildet. Ein derartiges Gittertragwerk weist ein vergleichsweise geringes Volumen auf, wenn sich die Strukturen in der nicht aufgespreizten Position befinden und ist auf ein vergleichsweise großes Volumen erweiterbar, wenn die Strukturen aufgespreizt werden. Das Gittertragwerk kann permanent oder vorübergehend eingesetzt werden und beispielsweise als Stützkonstruktion dienen oder ein Teil einer solchen Konstruktion bilden.This object is achieved by a lattice support structure with the features of claim 1. Thereafter, it is envisaged that the lattice structure will have repetitive, successive structures which are expandable into a pyramidal or truncated pyramidal structure, with the tip of one of the structures communicating with or forming part of the base of the adjacent structure. Such a truss structure has a comparatively small volume when the structures are in the unexpanded position and is expandable to a comparatively large volume when the structures are spread. The lattice structure can be permanently or temporarily used and serve as a support structure or form part of such a construction.
Denkbar ist es, dass an den Eckpunkten der Grundflächen der aufgespreizten Strukturen Gitterstäbe ansetzen, die die Strukturen miteinander verbinden. Dabei kann es sich um gerade Stangen handeln, die an Eckpunkten der Grundflächen ansetzen und mehrere Strukturen miteinander verbinden.It is conceivable that at the vertices of the base surfaces of the spread structures grid bars set that connect the structures together. These can be straight rods that attach to corner points of the base surfaces and connect several structures with each other.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Grundflächen der aufgespreizten Strukturen durch Gitterstäbe begrenzt werden, die aus zwei oder mehr als zwei gelenkig miteinander verbundenen Segmenten bestehen. Diese Gitterstäbe können in dem aufgespreizten Zustand der Strukturen gerade und im nicht aufgespreizten Zustand der Strukturen gewinkelt angeordnet sein.In a further embodiment of the invention, it is provided that the bases of the spread structures are limited by bars consisting of two or more than two articulated interconnected segments. These bars can be arranged in the spread state of the structures straight and in the non-spread state of the structures angled.
Des weiteren kann vorgesehen sein, dass sich von den Spitzen der Strukturen Streben zu den Eckpunkten der Grundflächen der aufgespreizten Strukturen erstrecken, die mit den Spitzen gelenkig in Verbindung stehen und/oder die aus zwei oder mehr als zwei gelenkig miteinander verbundenen Segmenten bestehen. Die Strukturen können ferner Gitterstäbe aufweisen, die von der Grundfläche der aufgespreizten Strukturen, vorzugsweise von den Eckpunkten der Grundflächen der aufgespreizten Strukturen zu der Spitze der Strukturen verlaufen und dabei die Kanten der Strukturen bilden, die die Grundfläche mit der Spitze der Struktur verbinden.Furthermore, it can be provided that struts extend from the tips of the structures to the corner points of the base surfaces of the spread-apart structures, which are articulated to the tips and / or which consist of two or more than two articulated segments. The structures may further comprise grid bars extending from the base of the spread structures, preferably from the vertices of the bases of the spread structures to the top of the structures, thereby forming the edges of the structures connecting the base to the top of the structure.
Weiterhin kann vorgesehen sein, dass die Grundflächen der aufgespreizten Strukturen drei- oder viereckig, vorzugsweise quadratisch, oder polygon ausgeführt sind.Furthermore, it can be provided that the base surfaces of the spread-open structures are designed as three or quadrangular, preferably square, or polygonal.
Die Erfindung betrifft des weiteren ein Gittertragwerk mit aufspreizbaren Strukturen, insbesondere ein Gittertragwerk nach einem der Ansprüche 1 bis 6, wobei das Gittertragwerk schwenkbar angeordnete Gitterstäbe aufweist, wobei die schwenkbare Verbindung derart ausgeführt ist, dass eines der miteinander schwenkbar verbundenen Teile einen Vorsprung aufweist und dass das andere der schwenkbar verbundenen Teile eine auf drei Seiten durch Wandungen begrenzte Nut aufweist, in der der Vorsprung des anderen Teils verschwenkbar aufgenommen ist. Der Nutboden dient somit als Begrenzung, so dass ein Verschwenken des Gitterstabes nur soweit möglich ist, bis das eine der genannten Teile an dem Nutboden aufliegt. In dieser Position ist der Gitterstab somit blockiert bzw. ein weiteres Verschwenken ist nicht möglich. Eine derartige schwenkbare Verbindung kann dort vorgesehen sein, wo zwei Segmente eines Gitterstabes schwenkbar miteinander in Verbindung stehen und/oder wo ein Gitterstab an einem anderen Teil des Gittertragwerks angelenkt ist.The invention further relates to a lattice support structure with expandable structures, in particular a lattice support structure according to one of claims 1 to 6, wherein the lattice structure has pivotally arranged bars, wherein the pivotable connection is designed such that one of the pivotally connected parts has a projection and that the other of the pivotally connected parts has a limited on three sides by walls groove in which the projection of the other part is pivotally received. The groove bottom thus serves as a boundary, so that a pivoting of the grid bar is only possible as far as possible, until one of said parts rests against the groove bottom. In this position, the grid is thus blocked or further pivoting is not possible. Such a pivotable connection may be provided where two segments of a grid bar pivotally communicate with each other and / or where a grid bar is hinged to another part of the lattice support structure.
Der Gitterstab kann an seinem einen Endbereich den Vorsprung und an seinem anderen Endbereich die genannte Nut aufweisen. Auf diese Weise ist es möglich, mehrere Gitterstäbe miteinander zu verbinden bzw. Gitterstäbe unterschiedlicher Länge bereitzustellen. Grundsätzlich ist auch denkbar, beiden Enden des Gitterstabes mit Nuten oder mit den genannten Vorsprüngen auszuführen.The grating bar may have the projection at its one end region and the said groove at its other end region. In this way it is possible to connect a plurality of bars together or to provide bars of different lengths. In principle, it is also conceivable to carry out both ends of the lattice bar with grooves or with the said projections.
Besonders vorteilhaft ist es, wenn eine Brems- bzw. eine Fixiereinrichtung vorgesehen ist, die die Gitterstäbe in einer bestimmten Schwenkposition fixiert. Dabei kann es sich beispielsweise um eine Trommel-, Scheiben oder Backenbremse handeln. Die Bremse kann z.B. hydraulisch oder mechanisch betätigt sein. Die Bremse kann Bremsbacken aufweisen, die zwei Vorsprünge aufweisen, die bei Betätigung der Bremse gleichzeitig mit dem jeweils benachbarten Teil, beispielsweise mit dem genannten Vorsprung in Kontakt tritt und so eine optimale Bremswirkung entfaltet.It is particularly advantageous if a brake or a fixing device is provided which fixes the grid bars in a specific pivot position. there it may be, for example, a drum, disc or jaw brake. The brake can be actuated hydraulically or mechanically, for example. The brake may comprise brake shoes which have two projections which, upon actuation of the brake, simultaneously come into contact with the respectively adjacent part, for example with the said projection, and thus develop an optimal braking effect.

Die die Spitzen der Strukturen 10 bildenden Grundflächen sind durch ein nicht dargestelltes Betätigungselement, beispielsweise eine Stange oder ein Kabel verbunden. Je nach Richtung der Betätigung der Stange oder des Kabels wird die Struktur aufgespreizt oder zusammengezogen. Wird das Betätigungselement gemäß dem nach oben weisenden Pfeil betätigt, wird das Gittertragwerk zusammengezogen, bei der Betätigung gemäß dem nach unten weisenden Pfeil auseinandergespreizt.The bases of the

Ein derartiges System ermöglicht es, im Bedarfsfall, beispielsweise bevor ein Hurricane auf die Küste auftrifft, an den gefährdeten Gebieten die Gittertragwerke 820 mittels der Fixierungspunkte 830 zu montieren, um die Küste entsprechend zu schützen. Dabei können die Gittertragwerke 820 im nicht aufgespreizten Zustand schnell an den gewünschten Ort transportiert werden, dort aufgespreizt und dann montiert werden. Grundsätzlich ist es natürlich ebenfalls möglich, die Gittertragwerke 820 erst zu montieren und dann aufzuspreizen. Aufgrund der lösbaren Verbindung zwischen den Gittertragwerken 820 und den Fixierungspunkten 830 können die Gittertragwerke 820 anschließend wieder abmontiert und verstaut werden.Such a system makes it possible, if necessary, for example, before a hurricane hits the coast, to mount the

In diesem Fall können die Gittertragwerke luftgefüllte Kammern aufweisen, die derart ausgeführt sein können, dass das Gittertragwerk 860 selbst schwimmfähig ist bzw. einen genügend hohen Auftrieb gewährleistet, dass ein Sinken des Schiffes 850 bzw. dessen Kentern bei hohem Seegang verhindert werden kann.The
