Abstract

The grid plate (1) has a peripheral frame (4) with a number of corners (2) joined together by side edges (3), with struts (5) within the frame extending between the corners. The spacing between 2 adjacent struts decreases moving away from one corner, before increasing again moving towards the next corner, or alternatively the struts exhibit an increasing longitudinal loading capacity moving away from the first corner and a decreasing loading capacity moving towards the next corner, provided by varying their cross-sectional geometry.

Description

Die Erfindung betrifft einen dreidimensionalen, kastenartigen Flüssigkeitsspeicher mit wenigstens einer Gitterplatte.The invention relates to a three-dimensional, box-like Liquid storage with at least one grid plate.

Aus der DE 39 03 265 A1 oder der US 4,619,371 sind Gitterplatten bekannt, um dreidimensionale Strukturen in Form faltbarer Transportkörbe zu schaffen. Derartige Transportkörbe sind nur geringen mechanischen Belastungen ausgesetzt und müssen in erster Linie den Innendruck aufnehmen können, der durch das Transportgut auf den Boden und die Gitterplatten einwirkt. Durch das Transportgut wirken Druckkräfte von innen nach außen gerichtet, quer zu der durch die Gitterplatte definierten Ebene, auf die Gitterplatte ein. Die US 2 718 325 zeigt einen Vorratsbehälter für Lebensmittel, für den dieselben Überlegungen gelten.From DE 39 03 265 A1 or US 4,619,371 are grid plates known to be foldable three-dimensional structures in the form To create transport baskets. Such transport baskets are only exposed to low mechanical loads and must be in First, the internal pressure can be absorbed by the Transport goods on the floor and the grid plates acts. Due to the transported goods compressive forces act from the inside to the outside directed, transversely to the plane defined by the grid plate, on the grid plate. US 2 718 325 shows a storage container for food, for the same considerations be valid.

Die GB 1 398 718 und die EP 0,169,572 A2 zeigen jeweils eine Gitterstruktur, die nicht als Wandung vorgesehen ist, sondern als leichtgewichtiger, voluminöser Kern für beispielsweise Flugzeugtragflächen oder Platten. Da es sich um eine Kernstruktur handelt, ist notwendigerweise eine äußere Umhüllung vorgesehen. Diese Umhüllung mag eventuell Verbindungs-mittel zur Anbindung an weitere Bauelemente aufweisen, die Kernstruktur selbst ist jedoch nicht zur Verbindung mit weiteren, gleichartigen Konstrukturen ausgelegt, sodass sie zur Verwendung als Wandung eines Kastens nicht geeignet ist.GB 1 398 718 and EP 0,169,572 A2 each show one Grid structure, which is not intended as a wall, but as a lightweight, voluminous core for aircraft wings, for example or plates. Because it is a core structure is an external enclosure is necessarily provided. This enclosure may be suitable for connecting to Have connection to other components, the core structure itself, however, is not for connection with other similar ones Constructs designed to be used as a wall a box is not suitable.

Niemann, G.: "Maschinenelemente" 1981, Springer-Verlag, Berlin, Heidelberg, DE XP 002188459 ISBN: 3-540-06809-0 betrifft Hinweise auf Möglichkeiten zur Gewichtseinsparung bei Leichtbau-Konstruktionen durch die Verwendung von Gitterstrukturen.Niemann, G .: "Machine Elements" 1981, Springer-Verlag, Berlin, Heidelberg, DE XP 002188459 ISBN: 3-540-06809-0 Indications of possibilities for weight saving in lightweight constructions through the use of lattice structures.

Die letztgenannten Druckschriften geben daher keine Hinweise zur Ausgestaltung eines dreidimensionalen Kastens.The latter documents therefore give no indication for the design of a three-dimensional box.

Bei kastenartigen Strukturen, die der Aufnahme von Flüssigkeit dienen, beispielsweise als Pufferspeicher zu Drainagezwecken im Erdreich, können sich hohe Druckbelastungen dadurch ergeben, dass die Bodenoberfläche oberhalb der kastenartigen Struktur von Fahrzeugen befahren wird. Der Druck wirkt im Gegensatz zu den eingangs genannten Transport- oder Lagerbehälten von außen auf die kastenartigen Strukturen ein.In box-like structures, the intake of liquid serve, for example as a buffer for drainage purposes in the soil, high pressure loads can result that the soil surface above the boxy Structure of vehicles is driven. The pressure works in contrast to the aforementioned transport or storage containers from the outside on the box-like structures.

Die WO 01/53608 A1, WO 95/16833 A1, EP 0,943,737 A1 zeigen Drainagetanks mit gitterartig strukturierten Wandelementen, wobei die gitterartige Struktur der Wandelemente jeweils gleichmäßig ausgestaltet ist. Zur Aussteifung des Drainagetanks ist gemäß der EP 0,943,737 A1 eine Vielzahl von Zapfen vorgesehen, die das nutzbare Innenvolumen des Drainagetanks deutlich reduzieren.WO 01/53608 A1, WO 95/16833 A1, EP 0,943,737 A1 show Drainage tanks with grid-like structured wall elements, wherein the lattice-like structure of the wall elements respectively is designed evenly. For stiffening the drainage tank is provided according to EP 0,943,737 A1 a plurality of pins, the apparent inner volume of the drainage tank clearly to reduce.

Der Erfindung liegt die Aufgabe zugrunde, gattungsgemäße Gitterplatten dahingehend zu verbessern, daß sie eine dreidimensionale Struktur mit hoher Druckfestigkeit gegenüber einem von außen einwirkendem Druck ermöglichen.The invention is based on the object, generic To improve the grid plates so that they have a three-dimensional Structure with high pressure resistance compared allow an externally applied pressure.

Diese Aufgabe wird durch einen Flüssigkeitsspeicher mit den Merkmalen des Anspruches 1 oder des Anspruchs 2 gelöst.This object is achieved by a liquid storage with the Characteristics of claim 1 or claim 2 solved.

Die Erfindung schlägt mit anderen Worten vor, die Druckbelastbarkeit entlang einer Kante des Rahmens von den beiden Ecken hin zu einem mittleren Bereich dieser Kante hin zu verbessern, d. h. zu verstärken.In other words, the invention proposes the compressive strength along one edge of the frame from the two corners towards a middle area of that edge, d. H. to reinforce.

Diese Verstärkung kann gemäß Anspruch 1 durch engere Abstände benachbarter Streben verwirklicht werden oder gemäß Anspruch 2 durch stabilere Streben. Stabilere Streben wiederum können durch größere Materialstärke verwirklicht werden, also durch die Querschnittsabmessungen bei grundsätzlich gleicher Formgebung, oder durch eine druckstabilere Querschnittsgeometrie.This gain can according to claim 1 by closer distances neighboring aspirations or according to Claim 2 by more stable struts. More stable striving in turn can be realized by greater material thickness, ie by the cross-sectional dimensions at basically the same Shaping, or by a pressure-stable cross-sectional geometry.

Die Erfindung geht dabei von der Überlegung aus, daß derartige Gitterplatten als aufrechtstehende Stirnwandungen einer kastenartigen dreidimensionalen Struktur verwendbar sind oder als innen in einer derartigen Struktur zusätzlich angeordnete Stützplatten. Die Druckbelastung erfolgt daher von außen und die Druckkräfte werden innerhalb der durch die Gitterplatte selbst definierten Ebene aufgefangen.The invention is based on the consideration that such Grid plates as upright end walls of a box-like three-dimensional structure are usable or as inside additionally arranged in such a structure support plates. The pressure load is therefore from the outside and the Compressive forces are within the through the grid plate itself defined level.

Die Erfindung geht dabei weiterhin von der Überlegung aus, daß die geringste Druckstabilität der Kanten jeweils dort zu erwarten ist, wo sie den größten Abstand von einer ihrer beiden Ecken aufweisen. An den Ecken selbst ergibt sich eine Stützwirkung durch die an der Ecke anschließende weitere Kante des Rahmens, so daß hier auch dann eine ausreichend gute Druckbelastbarkeit gegeben ist, wenn hier der Abstand benachbarter Streben vergleichsweise groß ist oder die Strebenquerschnitte weniger druckbelastbar sind, beispielsweise durch eine verringerte Materialstärke oder durch eine für Druckbelastungen vergleichsweise ungünstige Querschnittsgeometrie.The invention is still based on the consideration that the lowest pressure stability of the edges can be expected there is where you have the greatest distance from one of its two corners exhibit. At the corners itself gives a support effect through the edge of the frame that adjoins the corner, so that even then a sufficiently good compressive strength is given, if here the distance neighboring Struts are comparatively large or the strut cross sections less pressure resistant, for example, by a reduced Material thickness or by a for pressure loads comparatively unfavorable cross-sectional geometry.

Durch die erfindungsgemäße Anordnung der Streben wird eine möglichst große Druckbelastbarkeit einer Kante auch im Abstand von den Ecken der Gitterplatte ermöglicht. Dabei wird gleichzeitig eine möglichst große Materialeinsparung verwirklicht, indem zu den Ecken hin die Druckbelastbarkeit der Kante verringert wird.The inventive arrangement of the struts is a the greatest possible compressive strength of an edge even at a distance from the corners of the grid plate allows. It will at the same time realizes as much material savings as possible, by the pressure load capacity of the edge towards the corners is reduced.

Dies bedeutet einerseits aufgrund der Materialeinsparung eine kostengünstige Herstellungsmöglichkeit, andererseits für Anwendung, Montage und Verlegung eine leichtere Handhabbarkeit durch geringeres Gewicht, und schließlich je nach Einsatzzweck der mit Hilfe der Gitterplatten hergestellten Strukturen optimale Eigenschaften dieser Strukturen. Werden mit Hilfe der Gitterplatten beispielsweise allseitig geschlossene, kastenartige Strukturen gebildet, die der Aufnahme von Flüssigkeit dienen, beispielsweise als Pufferspeicher zu Drainagezwecken im Erdreich, so ergibt sich durch die hohe Druckbelastbarkeit eine problemlose Überfahrbarkeit der Bodenoberfläche auch durch schwere Fahrzeuge und andererseits ein möglichst großes freies Innenvolumen des im Erdreich angeordneten Drainagetanks zur Aufnahme eines Maximums an Wasser.This means on the one hand due to the material savings one cost-effective production possibility, on the other hand for application, Assembly and installation easier handling through lighter weight, and finally depending on the purpose the structures produced with the help of the grid plates optimal Properties of these structures. Be with the help of Grid plates, for example, closed on all sides, box-like Formed structures that serve to absorb liquid, for example as a buffer for drainage purposes in the soil, so results from the high pressure capacity a easy to pass over the soil surface also by heavy vehicles and on the other hand the largest possible free Internal volume of the drainage tank located in the ground to absorb a maximum of water.

Vorteilhaft kann vorgesehen sein, zusätzlich zu kantenparallel verlaufenden Streben auch diagonal verlaufende Streben zu verwenden. Bei sich ändernden Abständen der kantenparallel verlaufenden Streben zueinander kann dabei durch die Diagonalstreben ein polygonartiger, nahezu gebogener Verlauf dieser Diagonalstreben und damit eine seitliche Ableitung der vertikal einwirkenden Druckkräfte erfolgen, so daß eine besonders vorteilhafte, großflächige Lastverteilung und damit eine besonders hohe Druckstabilität erzielt wird.Advantageously, it can be provided, in addition to parallel edges extending struts and diagonal struts too use. At changing distances of the edges parallel extending struts to each other can be achieved by the diagonal struts a polygonal, almost curved course of this Diagonal struts and thus a lateral derivative of the vertical acting compressive forces take place, so that a particularly advantageous, large-scale load distribution and thus a special high pressure stability is achieved.

Zusätzlich zu der optimierten Ausgestaltung der Streben an den Kanten des Rahmens kann eine weitere Materialeinsparung der Gitterplatte in der Flächenmitte dadurch vorgesehen werden, daß dort weniger Material der Gitterplatte vorgesehen ist, beispielsweise dort keine oder weniger Streben vorgesehen sind oder Streben mit geringerem Querschnitt. Insbesondere wenn aufgrund der vorerwähnten polygonartigen oder bogenförmigen Kraftableitung der mittlere Flächenbereich der Gitterplatte von Druckbelastungen im wesentlichen frei ist, kann hier eine erhebliche Materialeinsparung und damit eine entsprechend große Schaffung freien Volumens ermöglicht werden.In addition to the optimized design of the struts to the Edges of the frame can save further material Grid plate can be provided in the center of the area, that there less material of the grid plate is provided, for example There are no or less struts are provided or struts with a smaller cross-section. Especially if due to the aforementioned polygonal or arcuate Power dissipation of the mean surface area of the grid plate of Pressure loads is essentially free, here can be a significant Material savings and thus a correspondingly large Creation of free volume will be made possible.

In Fig. 1 ist mit 1 allgemein eine Gitterplatte bezeichnet, die nahezu quadratisch ausgestaltet ist und vier Ecken 2 aufweist, wobei zwischen den Ecken 2 jeweils Kanten 3 verlaufen, die insgesamt einen viereckigen, nahezu quadratischen Rahmen 4 bilden. Innerhalb des Rahmens 4 verlaufen Streben 5.

Within the frame 4 struts run 5.

Einige dieser Streben 5 verlaufen parallel zu den Kanten 3 und sind als kantenparallele Streben 5a gekennzeichnet. Durch die sich kreuzenden kantenparallelen Streben 5a werden Zellen gebildet, durch welche sich schräg verlaufende Streben erstrecken, die als Diagonalstreben 5b gekennzeichnet sind.Some of these struts 5 are parallel to the edges 3 and are marked as edge-parallel struts 5a. By the intersecting edge-parallel struts 5a become cells formed, through which extend oblique struts, which are marked as diagonal struts 5b.

Wo sich die kantenparallelen Streben 5a kreuzen, sind zur Vermeidung von Materialhäufungen Bohrungen 6 vorgesehen, die zudem Druckkräfte vorteilhaft verteilen, welche in Richtung der Plattenebene wirken.Where the edge-parallel struts 5a intersect are to be avoided provided by material clusters holes 6, the also distribute pressure forces advantageous, which in the direction of Disk level act.

An der Außenseite des Rahmens 4 sind Zapfen 7 vorgesehen, die zur Verbindung mit weiteren Gitterplatten dienen. Die Zapfen weisen eine Basis mit etwa kreisrundem Querschnitt auf sowie ein von der Basis 8 entferntes freies Ende 9, an dem jeweils eine Kralle 10 vorgesehen ist. Um eine Elastizität und Verformbarkeit des Zapfens 7 zu ermöglichen, ist in der Basis 8 eine Nut 11 vorgesehen.On the outside of the frame 4 pins 7 are provided, which serve for connection to other grid plates. The cones have a base with approximately circular cross-section as well a remote from the base 8 free end 9, at the respectively a claw 10 is provided. To be elastic and deformable of the pin 7 is in the base 8 a groove 11 provided.

Die Gitterplatte 1 weist rein beispielhaft vier Zellen auf, die nicht von Diagonalstreben 5b durchkreuzt sind, sondern die durch Platten 12 ausgefüllt sind. Diese Platten 12 dienen zur einfacheren Entnahme der Gitterplatte 1 aus einem Formwerkzeug mit Hilfe beispielsweise von Saughebern und können weiterhin zur Anbringung von Kennzeichnungen genutzt werden.The grid plate 1 has, purely by way of example, four cells which are not of diagonal struts 5b are crossed, but the through Plates 12 are filled. These plates 12 are for easier Removal of the grid plate 1 from a mold with Help, for example, from siphons and can continue to Attachment of markings are used.

In Fig. 2 ist eine korrespondierende, mit der Gitterplatte 1 von Fig. 1 verbindbare Gitterplatte 1 dargestellt, ebenfalls mit vier Platten 12. Diese Gitterplatte 1 der Fig. 2 weist ebenfalls Bohrungen 6 auf zur Vermeidung von Materialhäufungen und zudem größere Bohrungen in Form von Hülsen 14, die etwa in halber Höhe der Hülsen 14 innen umlaufende Kragen 15 aufweisen zum Zusammenwirken mit den Zapfen 7, wie anhand von Fig. 3 dargestellt ist: In Fig. 2 is a corresponding, with the grid plate 1 of Fig. 1 connectable grid plate 1 shown, also with four Plates 12. This grid plate 1 of Fig. 2 also has holes 6 on to avoid material clusters and also larger holes in the form of sleeves 14, which are in about half Height of the sleeves 14 inside circumferential collar 15 have for cooperation with the pins 7, as with reference to FIG. 3 is shown:

Eine untere Gitterplatte 1u ist im Bereich ihres Rahmens 4u dargestellt. Eine gleichartige Gitterplatte ist oben dargestellt und deren Bezugszeichen sind jeweils mit o gekennzeichnet, also ist dort ein Rahmen 4o einer Gitterplatte 1o ersichtlich, wobei sich von dieser oberen Gitterplatte 1o ein Zapfen 7o in eine Hülse 15m einer mittleren Gitterplatte 1m (Bezugszeichen mit m) erstreckt. Der Kragen 15m der Hülse 14m kann von beiden Zapfen 7o und 7u der oberen und der unteren Gitterplatten 1o und 1u hintergriffen werden, so daß auf diese Weise eine einfache, beliebig erweiterbare Anbaubarkeit mehrerer Gitterplatten ermöglicht wird und damit die Schaffung sehr großer Strukturen.A lower grid plate 1u is shown in the region of its frame 4u. A similar grid plate is shown above and their reference numerals are each marked with o , so there is a frame 4o a grid plate 1o seen, extending from this upper grid plate 1o a pin 7o in a sleeve 15m of a middle grid plate 1m (reference numeral with m ) , The collar 15m of the sleeve 14m can be engaged behind by both pins 7o and 7u of the upper and lower grid plates 1o and 1u, so that in this way a simple, any expandable attachability of several grid plates is made possible and thus the creation of very large structures.

In Fig. 4 ist ein Drainagetank ersichtlich, wie er beispielsweise als Wasserspeicher im Erdreich vorgesehen sein kann. Die Gitterplatten gemäß Fig. 2 sind dabei als Längsplatten 1b bezeichnet und die Gitterplatten gemäß Fig. 1 als Querplatten 1a, wobei diese Querplatten 1a sowohl die beiden Stirnplatten des Drainagetanks bilden als auch innerhalb des Drainagetanks als zusätzliche Stützplatten zur Erhöhung der Druckstabilität des Drainagetanks vorgesehen sind.In Fig. 4, a drainage tank is visible, as he, for example can be provided as a water reservoir in the ground. The Grid plates according to FIG. 2 are referred to as longitudinal plates 1b and the grid plates according to FIG. 1 as transverse plates 1a, these transverse plates 1a both the two end plates of the Drainage tanks form as well as within the drainage tank as additional support plates to increase the pressure stability of the Drainage tanks are provided.

Wie insbesondere aus Fig. 2 hervorgeht, weisen die Längsplatten 1b eine Vielzahl von Hülsen 14 auf, so daß eine Vielzahl von Querplatten 1a innerhalb einer solchen Drainagebox angeordnet werden können, je nach der gewünschten Druckfestigkeit.As can be seen in particular from Fig. 2, the longitudinal plates 1b a plurality of sleeves 14, so that a plurality of Cross plates 1a disposed within such a drainage box can be, depending on the desired compressive strength.

Druckkräfte, die von oben auf die Drainagebox einwirken, wirken also in der Ebene, in der die Querplatten 1a aufgestellt sind. Sie werden über die obere Kante 3 des Rahmens 4 einer Querplatten 1a in die Streben 5 der Querplatte eingeleitet.Compressive forces acting on the drainage box from above act So in the plane in which the transverse plates 1a are placed. she be over the upper edge 3 of the frame 4 of a transverse plates 1a introduced into the struts 5 of the transverse plate.

Anhand von Fig. 1 ist deutlich, daß die Abstände benachbarter kantenparalleler Streben 5a von einer Ecke 2 einer Kante zur Kantenmitte hin zunächst zunehmen und anschließend zur nächsten Ecke 2 hin wieder abnehmen. Auf diese Weise wird einem Stützeffekt Rechnung getragen, der sich im Bereich der Ecke durch die jeweils benachbarte Kante 3 des Rahmens 4 ohnehin ergibt. Durch die in den Eckbereichen größeren Abstände zwischen benachbarten Streben 5 kann demzufolge Material gespart werden und ein dementsprechend größeres Aufnahmevolumen des Drainagetanks für Wasser ermöglicht werden.With reference to Fig. 1 it is clear that the distances adjacent edge-parallel struts 5a from a corner 2 of an edge to Increase edge center first and then to take off next corner 2 again. This way will accounted for a supporting effect, which is in the area of Corner by the respective adjacent edge 3 of the frame. 4 anyway results. Due to the larger distances in the corners between adjacent struts 5 can accordingly Material can be saved and a correspondingly larger Intake volume of the drainage tank for water allows become.

Da die Abstände der kantenparallelen Streben 5a jeweils an zwei benachbarten Kanten 3 jeweils von der Ecke aus geringer werden, ergibt sich für die Diagonalstreben 5b aufgrund der unterschiedlichen und nicht immer quadratischen Zellengrößen von der Mitte einer Kante 3 ausgehend ein gebogener, die Kraft nach außen kurvig ableitender Verlauf bis zu der rechts oder links von der Kante 3 benachbarten Kante 3. Die kantenparallelen Streben 5a hingegen leiten die Druckkräfte nach unten. An den Krezungspunkten der verschiedenen Streben ergibt sich eine weitere Verteilung und Aufzweigung der Druckkräfte, so daß insgesamt eine sehr stabile und hoch belastbare Ausgestaltung der Querplattenn 1a und damit des gesamten Drainagetanks resultiert.Since the distances of the edge-parallel struts 5a each two adjacent edges 3 each lower from the corner be, results for the diagonal struts 5b due to the different and not always square cell sizes starting from the middle of an edge 3 starting a bent, the force outward curvy course leading to the right or to the left of the edge 3 adjacent edge 3. The edge-parallel However, struts 5a direct the pressure forces downwards. At The points of intersection of the different struts are given a further distribution and branching of the compressive forces, so that overall a very stable and highly resilient design the transverse plates 1a and thus the entire drainage tank results.
