Description

Die Erfindung betrifft einen Transport- und Lagerbehälter für Flüssigkeiten nach dem Oberbegriff des Anspruchs 1.The invention relates to a transport and storage container for liquids according to the preamble of claim 1.

Bekannte Transport- und Lagerbehälter für Flüssigkeiten umfassen neben einem Innenbehälter aus Kunststoff einen insbesondere aus einem Metallgitterrahmen oder Blech gebildeten Außenmantel sowie ein palettenartiges Untergestell, welches zur Handhabung mittels Hubstapler, Regalbediengerät oder dergleichen Transportmittel eingerichtet ist. Das Untergestell weist einen Boden zur Abstützung des Innenbehälters und einen Grundrahmen mit Stützfüßen auf. Der Boden weist eine Stützfläche für den Innenbehälter und einen durch einen Bodenwall von der Stützfläche abgeteilten Auflagerand auf, welcher zwischen einem Unterrand des Außenmantels und dem Grundrahmen angeordnet ist. Der Unterrand des Außenmantels ist an zumindest einer Verbindungsstelle mittels einer über den Auflagerrand auf den Grundrahmen wirkenden Verbindung kraftschlüssig mit dem Grundrahmen verbunden.Known transport and storage containers for liquids comprise, in addition to an inner container made of plastic, an outer casing formed in particular from a metal grid frame or sheet, as well as a pallet-like underframe, which is set up for handling by means of a lift truck, stacker crane or similar means of transport. The base frame has a bottom for supporting the inner container and a base frame with support feet. The bottom has a support surface for the inner container and a support edge partitioned by a bottom wall from the support surface, which is disposed between a lower edge of the outer shell and the base frame. The lower edge of the outer shell is connected to at least one connection point by means of a force acting on the base frame via the support edge connection frictionally with the base frame.

Bei den bekannten Transport- und Lagerbehältern bildet somit der Boden auf dem Grundrahmen die unterseitige Begrenzung eines Aufnahmeraums für den Innenbehälter aus Kunststoff. Der Außenmantel bildet die seitlichen Begrenzungen und die oberseitige Begrenzung des Aufnahmeraums. Im Ergebnis bildet also mit anderen Worten die Kombination aus Boden auf dem Grundrahmen und Außenmantel eine Hüllstruktur für den Innenbehälter aus Kunststoff, an der der Innenbehälter, insbesondere im befüllten Zustand, ganz oder teilweise Halt finden kann und positioniert bleibt. Bei Krafteinwirkung auf die Hüllstruktur, beispielsweise durch einen erhöhten Druck im Innenbehälter oder infolge von Schwallschwingungen des Füllgutes während des Transports, kann es infolge der mechanischen Beanspruchung zu einer verstärkten Belastung oder einer Verformung der Hüllstruktur kommen.In the known transport and storage containers thus forms the bottom of the base frame, the lower boundary of a receiving space for the inner container made of plastic. The outer jacket forms the lateral boundaries and the upper-side boundary of the receiving space. As a result, in other words, the combination of base on the base frame and outer shell forms an enveloping structure for the inner container made of plastic, on which the inner container, especially when filled, can find wholly or partially support and remains positioned. Upon application of force to the enveloping structure, for example as a result of increased pressure in the inner container or as a result of swaying vibrations of the contents during transport, an increased load or deformation of the enveloping structure may occur as a result of the mechanical stress.

Um das Risiko einer Beschädigung des Innenbehälters durch eine übermäßig belastete oder verformte Hüllstruktur zu reduzieren, ist es wünschenswert, die Hüllstruktur möglichst steif auszubilden, damit die entsprechenden Belastungen oder Verformungen der Hüllstruktur möglichst klein bleiben. Andererseits soll natürlich der Innenbehälter möglichst positioniert in der Hüllstruktur angeordnet sein, wozu insbesondere der die Stützfläche des Bodens einrahmende Bodenwall ausgebildet ist. Durch diesen Bodenwall wird jedoch in mechanischer Hinsicht eine, die Steifigkeit des Bodens reduzierende Nachgiebigkeitsstelle ausgebildet, so dass sich der Bodenwall nachteilig betreffend die Ausbildung einer möglichst steif ausgebildeten Hüllstruktur auswirkt.In order to reduce the risk of damage to the inner container by an excessively loaded or deformed envelope structure, it is desirable to form the envelope structure as stiff as possible so that the corresponding loads or deformations of the envelope structure remain as small as possible. On the other hand, of course, the inner container should be positioned as possible positioned in the enveloping structure, including in particular of the support surface of the bottom framing bottom wall is formed. By this bottom wall, however, is formed in mechanical terms, the rigidity of the soil-reducing yield point, so that the bottom wall adversely affects the formation of a stiff as possible formed envelope structure.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Transport- und Lagerbehälter für Flüssigkeiten vorzuschlagen, der einerseits die gewünschte positionierende Anordnung des Innenbehälters mit einem die Stützfläche des Bodens einrahmenden Bodenwall ermöglicht und andererseits eine möglichst steif ausgebildete Hüllstruktur aufweist.The present invention is therefore based on the object to propose a transport and storage container for liquids, on the one hand allows the desired positioning arrangement of the inner container with a support surface of the bottom framing bottom wall and on the other hand has a stiff as possible formed envelope structure.

Zur Lösung dieser Aufgabe weist der erfindungsgemäße Transport- und Lagerbehälter die Merkmale des Anspruchs 1 auf.To solve this problem, the transport and storage container according to the invention has the features of claim 1.

Erfindungsgemäß weist der Boden des Transport- und Lagerbehälters, der mit einem die Stützfläche von einem Auflagerand abteilenden Bodenwall versehen ist, im Bereich von zumindest einer Verbindungsstelle, in der eine Krafteinleitung vom Außenmantel in den Boden erfolgt, eine Reduzierung der Wallhöhe, also eine Wallabsenkung auf. Durch diese Wallabsenkung, die im Bereich der Verbindungsstelle ausgebildet ist, so dass ansonsten die gewünschte positionierende Wirkung des Walls nicht beeinträchtigt wird, ist der Boden in unmittelbarer Nachbarschaft zur Verbindungsstelle steifer ausgebildet als im übrigen Bereich. Diese Erhöhung der Steifigkeit hat zur Folge, dass der Boden im Bereich der Verbindungsstelle eine vergleichsweise erhöhte Zugspannung aufnehmen kann, ohne dass damit eine Verformung des Bodens und damit eine entsprechende Verformung der Hüllstruktur verbunden wäre.According to the invention, the bottom of the transport and storage container, which is provided with a base wall dividing the support surface from a support edge, in the region of at least one connection point, in which a force is introduced from the outer shell into the ground, a reduction of the ramp height, ie a ramp lowering , By this ramp lowering, which is formed in the region of the connection point, so that otherwise the desired positioning effect of the wall is not affected, the soil in the immediate vicinity of the joint is made stiffer than in the remaining area. This increase in stiffness has the consequence that the soil in the region of the joint can absorb a comparatively increased tensile stress, without a deformation of the soil and thus a corresponding deformation of the enveloping structure would be connected.

Zur Erzielung dieses aufgrund der Erfindung ermöglichten Effekts ist es besonders vorteilhaft, wenn eine Reduzierung der Wallhöhe bis auf das Niveau der Stützfläche erfolgt. Grundsätzlich kann jedoch in Anwendung der erfindungsgemäßen Lehre bereits durch eine relativ geringfügige Absenkung bzw. Reduzierung der Wallhöhe eine vorteilhafte Erhöhung der Steifigkeit im Bereich der Verbindungsstelle erreicht werden.In order to achieve this effect made possible by the invention, it is particularly advantageous if the wall height is reduced to the level of the support surface. In principle, however, an advantageous increase in rigidity in the region of the connection point can already be achieved by applying a relatively slight lowering or reducing the height of the ramp when the teaching according to the invention is used.

Besonders vorteilhaft ist es, wenn die Wallabsenkung stetig in Form einer Rampe von einer Wallkrone zur Stützfläche hin erfolgt, so dass abrupte Querschnittsübergänge vermieden werden und somit nur relativ kleine Richtungsänderungen im Kraftfluss die Folge sind. Hierdurch wird insbesondere der Ausbildung von Verformungsrissen im Bereich der Verbindungsstelle vorgebeugt.It is particularly advantageous if the rampart lowering takes place continuously in the form of a ramp from a rampart to the supporting surface, so that abrupt cross-sectional transitions are avoided and thus only relatively small changes in direction in the power flow are the result. As a result, in particular the formation of deformation cracks in the region of the joint is prevented.

Wenn die Wallabsenkung in zumindest zwei einander gegenüberliegenden Bereichen des Auflagerandes ausgebildet ist, lässt sich die versteifende Wirkung noch erhöhen.If the rampart reduction is formed in at least two opposing areas of the support rim, the stiffening effect can be increased even more.

Besonders vorteilhaft ist es auch, wenn die Wallabsenkung im Bereich eines Stützfußes des Grundrahmens ausgebildet ist und somit die denIt is also particularly advantageous if the ramp lowering is formed in the region of a support foot of the base frame and thus the the

Boden versteifende Wirkung des Stützfußes an dieser Stelle noch weiter erhöht wird.Floor stiffening effect of the support foot is further increased at this point.

Wenn die Wallabsenkung im Bereich eines hinteren mittleren Stützfußes ausgebildet ist, der gegenüberliegend einer Bodenabsenkung für einen Auslauf des Innenbehälters angeordnet ist, lässt sich im Zusammenwirken mit der Wallabsenkung im Bereich eines hinteren mittleren Stützfu-βes eine versteifte Zugspannungsachse ausbilden.If the ramp lowering is formed in the region of a rear central support leg, which is arranged opposite a bottom lowering for an outlet of the inner container, a stiffened tensile stress axis can be formed in cooperation with the ramp lowering in the region of a rear central Stützfu-βes.

Bei einer besonders bevorzugten Ausführungsform des Transport- und Lagerbehälters weist der Grundrahmen ein zwei gegenüberliegende Stützfüße traversenartig verbindendes Versteifungsblech auf, wobei die Wallabsenkung im Bereich der zwei gegenüberliegenden Stützfüße ausgebildet ist, so dass die den Boden versteifende Wirkung des Versteifungsblechs noch durch die Wallabsenkungen im Bereich der Stützfüße erhöht wird.In a particularly preferred embodiment of the transport and storage container, the base frame has a two opposite support legs truss-like connecting stiffening plate, wherein the ramp lowering is formed in the region of the two opposite support legs, so that the bottom stiffening effect of the stiffening sheet still by the Wallabsenkungen in the Support feet is increased.

Nachfolgend wird eine Ausführungsform anhand der Zeichnung näher erläutert.Hereinafter, an embodiment will be explained in more detail with reference to the drawing.

Fig. 1 zeigt einen Transport- und Lagerbehälter 10 mit einem Innenbehälter 11 aus Kunststoff, der in eine den Innenbehälter 11 vor mechanischen Belastungen abschirmenden Hüllstruktur 12 angeordnet ist. Die Hüllstruktur 12 des Transport- und Lagerbehälters 10 weist einen auf einem palettenartigen Untergestell 13 angeordneten Außenmantel 14 auf, der im vorliegenden Fall aus einer Vielzahl von einander zur Ausbildung einer Gitterstruktur kreuzenden Horizontalstäben 15 und Vertikalstäben 16 ausgebildet ist. Fig. 1 shows a transport and storage container 10 with an inner container 11 made of plastic, which is arranged in a shielding the inner container 11 from mechanical loads envelope structure 12. The enveloping structure 12 of the transport and storage container 10 has an outer jacket 14 arranged on a pallet-like subframe 13, which in the present case is formed from a multiplicity of horizontal bars 15 and vertical bars 16 crossing each other to form a grid structure.

Der Außenmantel 14 liegt mit einem im vorliegenden Fall durch einen unteren Horizontalstab 15 ausgebildeten Unterrand 17 auf einem Boden 18 des Untergestells 13 auf. Im vorliegenden Fall sind zur ergänzenden Aussteifung am oberen Rand des Außenmantels 14 zusätzliche Stabtraversen 35 vorgesehen.The outer jacket 14 rests on a bottom 18 of the underframe 13 with a lower edge 17 formed in the present case by a lower horizontal bar 15. In the present case 14 additional bar cross members 35 are provided for supplemental stiffening at the top of the outer shell.

Wie aus einer Zusammenschau der Fig. 2 und 3 hervorgeht, ist der in Fig. 3 dargestellte Boden 18 auf einem insbesondere in Fig. 2 dargestellten Grundrahmen 19, angeordnet. Der Grundrahmen 19 weist ein umlaufendes Rahmenrohr 36 auf, das vier in den Rahmenecken vorgesehene Stützfüße 20, durch Endbereiche eines Versteifungsblechs 21 ausgebildete mittlere Stützfüße 22 und einen hinteren mittleren Stützfuß 23 aufweist, der, wie aus einer Zusammenschau mit Fig. 1 zu entnehmen ist, gegenüberliegend einer Bodenabsenkung 25 angeordnet ist, die einen mittleren vorderen Stützfuß 26 ausbildet.As if from a synopsis of FIGS. 2 and 3 is apparent in the Fig. 3 illustrated bottom 18 on a particular in Fig. 2 illustrated base frame 19, arranged. The base frame 19 comprises a peripheral frame tube 36 having four provided in the frame corners support legs 20, formed by end portions of a stiffening plate 21 central support legs 22 and a rear central support leg 23, which, as from a synopsis with Fig. 1 it can be seen opposite a bottom lowering 25 is arranged, which forms a central front support leg 26.

Wie eine Zusammenschau der Fig. 2 und 3 zeigt, liegt der Boden 18 mit einem Auflagerand 27 auf den Stützfüßen 20, 22 und 23 auf und weist parallel zum Auflagerand 27 verlaufend einen Bodenwall 28 auf, der eine Stützfläche 30 des Bodens 18 zur Abstützung des Innenbehälters 11 vom Auflagerand 27 abteilt und im Bereich der mittleren Stützfüße 22 jeweils mit einer Wallabsenkung 29 versehen ist.Like a synopsis of FIGS. 2 and 3 shows, the bottom 18 is located with a support edge 27 on the support legs 20, 22 and 23 and has parallel to the support edge 27 extending a bottom wall 28, a Support surface 30 of the bottom 18 for supporting the inner container 11 from the support edge 27 divides and is provided in the region of the middle support legs 22 each with a ramp lowering 29.

Fig. 4 zeigt in schematisch stark vereinfachter Darstellung einen Teilquerschnitt des Bodens 18 im Bereich einer Wallabsenkung 29. Im Vergleich hierzu zeigt Fig. 5 einen Teilquerschnitt des Bodens 18 im Bereich des Bodenwalls 28. Wie Fig. 4 zeigt, liegt der Boden 18 im Bereich der Wallabsenkung 29 mit dem Auflagerand 27 auf einem Verbindungssteg 33 des Stützfußes 22 auf. Der Auflagerand 27 ist zwischen dem Unterrand 17 des Außenmantels 14 und dem Verbindungssteg 33 aufgenommen, wobei zur Herstellung der kraftschlüssigen Verbindungsstelle 32 ein Verbindungsbolzen 37 den Unterrand 17 und den Boden 18 mit dem Verbindungssteg 33 des Stützfußes 22 verbindet. Infolge der Wallabsenkung 29 ist der Übergang vom Auflagerand 27 zur Stützfläche 30 bei dem dargestellten Ausführungsbeispiel Fig. 4 shows in a highly simplified schematic representation of a partial cross section of the bottom 18 in the region of a ramp lowering 29. In comparison shows Fig. 5 a partial cross section of the bottom 18 in the area of the bottom wall 28. Like Fig. 4 shows, the bottom 18 is in the region of the ramp lowering 29 with the support rim 27 on a connecting web 33 of the support leg 22. The support rim 27 is received between the lower edge 17 of the outer shell 14 and the connecting web 33, wherein a connecting pin 37 connects the lower edge 17 and the bottom 18 with the connecting web 33 of the support leg 22 for producing the non-positive connection point 32. As a result of the ramp lowering 29, the transition from the support edge 27 to the support surface 30 in the illustrated embodiment

Zwar zeigt auch die Darstellung in Fig. 5 , dass sich der Auflagerand 27 in einer Ebene mit der Stützfläche 30 des Bodens 18 befindet. Jedoch ist durch den Bodenwall 28 zwischen dem Auflagerand 27 und der Stützfläche 30 eine Welle im Boden 18 ausgebildet, so dass der Boden 18 im Bereich des Bodenwalls 28 eine vergleichsweise reduzierte Steifigkeit aufweist bei Einwirkung einer in den Fig. 4 und 5 dargestellten Zugkraft FZ. Der Bodenwall 28 bzw. die durch den Bodenwall 28 im Boden 18 ausgebildete Welle führt dazu, dass bei einer Zugbelastung unterhalb der Streckgrenze des für den Boden 18 verwendeten Materials im Falle der Fig. 4 dargestellten Wallabsenkung 29 keine Längung des Bodens 18 infolge der Zugbelastung erfolgt, wohingegen im Bereich des in Fig. 5 dargestellten Bodenwalls 28 in Richtung der Zugkraft FZ eine Längung des Bodens 18 erfolgt, die im Wesentlichen der Höhe h des Bodenwalls 28 entspricht. Somit ist festzustellen, dass der Boden 18 hinsichtlich einer in der Ebene des Bodens 18 wirkenden Zugbelastung im Bereich der in Fig. 4 dargestellten Wallabsenkung 29 steifer ausgebildet ist als im Bereich des in Fig. 5 dargestellten Bodenwalls 28.Although the illustration in Fig. 5 in that the support edge 27 is in a plane with the support surface 30 of the bottom 18. However, a wave in the bottom 18 is formed by the bottom wall 28 between the support rim 27 and the support surface 30, so that the bottom 18 in the region of the bottom wall 28 has a comparatively reduced rigidity when acting in the 4 and 5 shown tensile force F Z. The bottom wall 28 or formed by the bottom wall 28 in the bottom 18 shaft results in that at a tensile load below the yield strength of the material used for the bottom 18 in the case of Fig. 4 shown Wallabsenkung 29 no elongation of the bottom 18 due to the tensile load takes place, whereas in the area of in Fig. 5 bottom wall 28 shown in the direction of the tensile force F Z is a lengthening of the bottom 18, which corresponds substantially to the height h of the bottom wall 28. Thus, it should be noted that the bottom 18 in terms of acting in the plane of the bottom 18 tensile load in the area the in Fig. 4 wall lowering seen 29 is formed stiffer than in the area of Fig. 5 illustrated floor walls 28.

Wie auch Fig. 1 zu entnehmen ist, ist der Boden 18 mit seinem Auflagerand 27 so zwischen den Stützfüßen 20, 22 und 23 und dem Unterrand 17 des Außenmantels 14 angeordnet, dass der Boden 18 an den jeweils durch die Position der Stützfüße 20, 22 und 23 definierten Verbindungsstellen 32 gleichzeitig mit dem Unterrand 17 des Außenmantels 14 und mit dem Grundrahmen 19 verbunden ist. Hierzu sind in den Verbindungsstellen 32, wie bereits vorstehend erwähnt, die Verbindungsbolzen 37 vorgesehen.As well as Fig. 1 can be seen, the bottom 18 is arranged with its support edge 27 between the support legs 20, 22 and 23 and the lower edge 17 of the outer shell 14, that the bottom 18 at the respectively defined by the position of the support legs 20, 22 and 23 connecting points 32nd is connected simultaneously with the lower edge 17 of the outer shell 14 and with the base frame 19. For this purpose, in the connecting points 32, as already mentioned above, the connecting pins 37 are provided.

Fig. 6 zeigt in einer Schnittdarstellung des Transport- und Lagerbehälters 10 gemäß Schnittlinienverlauf VI-VI in Fig. 1 beispielhaft einen Belastungsfall, wie er bei einem ungleichmäßigen Aufsetzen des Transport- und Lagerbehälters 10 auf einem Unterboden infolge einer relativ zum Boden geneigten Anordnung des Transport- und Lagerbehälters 10 auftreten kann. In dem in Fig. 6 dargestellten Belastungsfall setzt der Transport- und Lagerbehälter 10 mit seiner Längsseite bei einem Absetzvorgang zuerst auf dem Untergrund auf. Die Folge hiervon ist eine Stauchung oder zumindest Druckbelastung der Hüllstruktur 12, so dass im Bereich der Verbindungsstelle 32 eine durch die Richtung der Vertikalstäbe 16 vorgegebene Druckkraft FD zusammen mit einer entsprechenden Reaktionskraft FR auf die Verbindungsstelle 32 wirkt und bedingt durch die Geometrie der Hüllstruktur 12 eine Zugkraft FZ im Boden 18 induziert wird, die längs einer zwischen den mittleren Stützfü-βen 22 ausgebildeten Belastungs- oder Zugachse 34 wirkt. Fig. 6 shows in a sectional view of the transport and storage container 10 according to section line VI-VI in Fig. 1 by way of example a loading case, as it can occur in a non-uniform placement of the transport and storage container 10 on a subfloor due to an inclined relative to the ground arrangement of the transport and storage container 10. In the in Fig. 6 shown load case, the transport and storage container 10 with its long side at a settling first on the ground. The consequence of this is a compression or at least pressure loading of the enveloping structure 12, so that in the region of the junction 32 a predetermined by the direction of the vertical bars 16 compressive force F D together with a corresponding reaction force F R acts on the junction 32 and due to the geometry of the enveloping structure 12, a tensile force F Z is induced in the floor 18, which acts along a loading or traction axis 34 formed between the middle support fins 22.

In dem in Fig. 6 dargestellten Belastungsfall wird nun der Boden 18 in Richtung der durch die Zugbelastung definierten Zugachse 34 zum einen wirksam versteift durch das unterhalb des Bodens 18 ausgebildete, an seinen Endbereichen die Stützfüße 22 ausbildende Versteifungsblech 21 und darüber hinaus dadurch, dass im Bereich der Verbindungsstellen 32 die Wallabsenkungen 29 im Bodenwall 28 ausgebildet sind. Dabei wird die Versteifung des Bodens 18 dadurch bewirkt, dass der Boden 18 im Bereich der Wallabsenkungen 29 im Vergleich zu dem zwischen den Verbindungsstellen 32 ausgebildeten Bodenwall 28 eine reduzierte Nachgiebigkeit aufweist.In the in Fig. 6 shown load case is now the bottom 18 in the direction of the tensile load defined by the tensile axis 34 effectively stiffened by the formed below the bottom 18, at its end the support legs 22 forming stiffening plate 21 and beyond in that in the region of the joints 32, the Wallabsenkungen 29 are formed in the bottom wall 28. It will the stiffening of the floor 18 is effected in that the floor 18 has a reduced compliance in the area of the wall depressions 29 in comparison with the floor wall 28 formed between the connection points 32.
