Description

Die vorliegende Erfindung betrifft ein palettenartiges Untergestell, insbesondere für Transport- und Lagerbehälter für Flüssigkeiten, die mit einem Innenbehälter aus Kunststoff mit einem verschließbaren Einfüllstutzen und einem Entleerstutzen zum Anschluss an eine Entnahmearmatur sowie einem Außenmantel aus einem Metallgitter oder Blech ausgestattet sind, wobei das Untergestell einen Boden zum Abstützen des Innenbehälters sowie Eck- und Mittelfüße aus Metall aufweist, die auf einem Fußrahmen angebracht sind und an denen der Boden des Untergestells befestigt ist, wobei die Eckfüße einen napfartigen Eckfußkörper aufweisen mit einer entsprechend einem Eckradius einer Rahmenecke des Fußrahmens gekrümmten Frontwandung und seitlich einer Mittelachse der Frontwandung ausgebildeten Napfteilen, wobei die Napfteile jeweils einen am Umfangsrand der Frontwandung ausgebildeten und nach innen abgewinkelten Randsteg aufweisen, mit einem oberen Randstegabschnitt zur Verbindung des Eckfußes mit dem Boden, einem unteren Randstegabschnitt zur Verbindung mit dem Fußrahmen und einem seitlichen Randstegabschnitt, der zwischen dem oberen und dem unteren Randstegabschnitt an einem Seitenrand der Frontwandung ausgebildet ist.The present invention relates to a pallet-like base, in particular for transport and storage containers for liquids, which are equipped with an inner container made of plastic with a closable filler neck and an emptying nozzle for connection to a removal fitting and an outer sheath of a metal grid or sheet metal, wherein the lower frame a Floor for supporting the inner container and corner and center feet of metal, which are mounted on a foot frame and to which the bottom of the underframe is attached, the Eckfüße having a cup-like Eckfußkörper with a corresponding corner radius of a frame corner of the Fußrahmens curved front and side a central axis of the front wall formed Cupfteilen, wherein the cup portions each have a formed on the peripheral edge of the front wall and angled inwardly edge web, with an upper edge web portion for connecting the E backfoot with the bottom, a lower edge web section for connection to the foot frame and a lateral An edge land portion formed between the upper and lower edge land portions on a side edge of the front wall.

Ein palettenartiges Untergestell der eingangs genannten Art ist beispielsweise aus der DE 202 17 856 U1 bekannt. Das bekannte Untergestell weist an den Rahmenecken des Fußrahmens angeordnete Eckfüße auf, die einen Eckfußkörper aufweisen mit zwei im Bereich einer Mittelachse ineinander übergehend ausgebildeten Napfteilen. Die Napfteile weisen jeweils am Oberrand der Frontwandung und am Unterrand der Frontwandung einen oberen Randstegabschnitt und einen unteren Randstegabschnitt auf, die im Wesentlichen rechtwinklig zur Frontwandung abgewinkelt sind. Dabei dient der obere Randstegabschnitt zur Verbindung mit dem Boden des Untergestells und der untere Randstegabschnitt zur Verbindung mit dem Fußrahmen des Untergestells.A pallet-like base of the type mentioned is, for example, from the DE 202 17 856 U1 known. The known base frame has arranged on the frame corners of the foot frame corner feet, which have a Eckfußkörper with two in the region of a central axis merge trained cup parts. The cup parts each have on the upper edge of the front wall and the lower edge of the front wall on an upper edge web portion and a lower edge web portion, which are angled substantially at right angles to the front wall. Here, the upper edge land portion for connection to the bottom of the undercarriage and the lower edge land portion for connection to the foot frame of the undercarriage.

An den Seitenrändern der Frontwandung sind die Napfteile mit einem seitlichen Randstegabschnitt versehen, der jeweils aus einer laschenförmig am Seitenrand der Frontwandung ausgebildeten Blechzunge besteht, die nach innen eingerollt ist und so ein Versteifungselement ausbildet, das mit seinen axialen Enden jeweils den oberen Randstegabschnitt und den unteren Randstegabschnitt abstützt, ohne dass die axialen Enden des Versteifungselements mit den Randstegabschnitten verbunden wären.At the side edges of the front wall, the cup parts are provided with a lateral edge web portion, each consisting of a tab-shaped on the side edge of the front wall tongue formed, which is rolled inwards and so forms a stiffening element, with its axial ends in each case the upper edge land portion and the lower Edge web portion supported without the axial ends of the stiffening element would be connected to the edge web sections.

Bei den bekannten Eckfüßen ermöglichen die Versteifungselemente insbesondere bei einer Belastung der Eckfüße parallel zur Mittelachse der Eckfüße eine wirksame Versteifung der Randstegabschnitte gegeneinander und somit eine entsprechende Erhöhung der Stabilität der Eckfüße. Ein entsprechender Belastungsfall ist beispielsweise durch die statische Belastung der Eckfüße bzw. des Untergestells bedingt durch den mit Flüssigkeit befüllten Innenbehälter eines Transport- und Lagerbehälters gegeben. Eine maximale statische Belastung ergibt sich daher bei einer Stapelanordnung mit mehreren übereinander angeordneten Transport- und Flüssigkeitsbehältern.In the known Eckfüßen allow the stiffening elements in particular at a load of the Eckfüße parallel to the central axis of the Eckfüße an effective stiffening of the edge web sections against each other and thus a corresponding increase in the stability of the Eckfüße. A corresponding load case is given, for example, by the static load on the corner feet or the underframe due to the liquid-filled inner container of a transport and storage container. A maximum static load therefore results in a stack arrangement with a plurality of transport and liquid containers arranged one above the other.

In einem Belastungsfall, bei dem die statische Last nicht parallel zur Mittelachse des Eckfußes wirkt oder auch bei einer dynamischen Belastung des Eckfußes, die beispielsweise bei der Handhabung eines Transport- und Lagerbehälters oder als Folge eines Behälterabsturzes oder eines ungleichmäßigen Aufsetzens des Behälters auf den Untergrund auftreten kann, müssen über die Versteifungselemente erhöhte Schubkräfte zwischen den oberen und unteren Randstegabschnitten übertragen werden, so dass die durch die seitlichen Randstegabschnitte gebildeten Versteifungselemente entsprechend stabil auszugestalten bzw. zu dimensionieren sind. Grundsätzlich ist es jedoch wünschenswert, zur Materialund Gewichtseinsparung möglichst dünne Bleche zur Herstellung der Eckfüße zu verwenden.In a load case in which the static load is not parallel to the central axis of the Eckfußes or even with a dynamic load of the Eckfußes, for example, when handling a transport and storage container or as a result of a container crash or uneven placement of the container on the ground occur can be transmitted via the stiffening elements increased thrust forces between the upper and lower edge web sections, so that the stiffening elements formed by the lateral edge web sections are designed to be stable or to dimension accordingly. In principle, however, it is desirable to use as thin as possible for the material and weight savings for the production of corner feet.

Die Erfindung geht von der grundsätzlichen Überlegung aus, die Stabilität der Versteifungselemente zur Übertragung der Schubbeanspruchung dadurch zu erhöhen, dass die axialen Enden der Versteifungselemente mit den benachbarten Randstegabschnitten verbunden werden. Dies kann beispielsweise durch eine stoffschlüssige Verbindung nach Art einer Schweißverbindung zwischen den axialen Enden der Versteifungselemente und den benachbarten Randstegabschnitten geschehen. Nachteilig an einer derartig ausgebildeten Verbindung ist jedoch, dass hierdurch ein gesonderter Bearbeitungsschritt bei der Herstellung der Eckfüße erforderlich wird.The invention is based on the fundamental idea of increasing the stability of the stiffening elements for transmitting the shear stress by connecting the axial ends of the stiffening elements to the adjacent edge web sections. This can be done for example by a cohesive connection in the manner of a welded joint between the axial ends of the stiffening elements and the adjacent edge web sections. However, a disadvantage of such a connection is that this requires a separate processing step in the manufacture of the corner feet.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein palettenartiges Untergestell für einen Transport- und Lagerbehälter für Flüssigkeiten vorzuschlagen, das eine erhöhte Stabilität aufweist, um somit die Bereitstellung von Transport- und Lagerbehältern für Flüssigkeiten zu ermöglichen, die eine erhöhte Sicherheit gegen ein durch mangelnde Stabilität des Untergestells bedingtes Behälterversagen gewährleisten und sich daher in besonderer Weise zum Transport und zur Lagerung von Gefahrgut eignen.The present invention is therefore an object of the invention to propose a pallet-like base for a transport and storage container for liquids, which has an increased stability, thus enabling the provision of transport and storage containers for liquids that increased security against a lack of Ensure stability of the undercarriage conditional container failure and therefore are particularly suitable for the transport and storage of dangerous goods.

Zur Lösung dieser Aufgabe weist das erfindungsgemäße Untergestell die Merkmale des Anspruchs 1 auf.To solve this problem, the subframe of the invention has the features of claim 1.

Bei dem erfindungsgemäßen Untergestell sind der obere Randstegabschnitt, der seitliche Randstegabschnitt und der untere Randstegabschnitt in Randstegumformbereichen kontinuierlich ineinander übergehend ausgebildet.In the undercarriage according to the invention, the upper edge web section, the lateral edge web section and the lower edge web section are formed continuously in edge web forming regions.

Bei dem erfindungsgemäßen Untergestell sind somit die Enden des seitlichen Randstegabschnitts einstückig mit dem oberen und dem unteren Randstegabschnitt verbunden, ohne dass besondere Verbindungen, die etwa in gesonderten Bearbeitungsvorgängen hergestellt werden müssten, notwendig sind. Vielmehr wir die Verbindung zwischen dem seitlichen Randstegabschnitt,dem oberen und dem unteren Randstegabschnitt durch einen Umformvorgang eines Blechzuschnitts hergestellt, der Bestandteil des Umformvorgangs ist, der zur Ausbildung bzw. Formung des napfartigen Eckfußkörpers bzw. der Napfteile des Eckfußkörpers notwendig ist.In the subframe according to the invention, therefore, the ends of the lateral edge web section are integrally connected to the upper and the lower edge web section, without special connections, which would have to be made approximately in separate machining operations, are necessary. Rather, we made the connection between the lateral edge web section, the upper and the lower edge web section by a forming process of a sheet metal blank, which is part of the forming process, which is necessary for the formation or shaping of the cup-like Eckfußkörpers or the cup parts of Eckfußkörpers.

Eine besondere Stabilität der Randstegumformbereiche wird ermöglicht, wenn diese als räumliche Eckbereiche der Napfteile ausgebildet sind, da diese Eckbereiche Kräfte in allen drei Kraftrichtungen des Raumes aufnehmen können.A special stability of the Randstegumformbereiche is made possible if these are designed as spatial corner regions of the cup parts, as these corner areas can absorb forces in all three directions of force of the room.

Eine weitere Versteifung des Untergestells kann dadurch erreicht werden, dass in die Frontwandung der Eckfüße Versteifungssicken eingeformt sind, die sich zwischen dem oberen Randstegabschnitt und dem unteren Randstegabschnitt erstrecken und einen Sickenboden aufweisen, der gegenüber einer durch die Frontwandung definierten Frontebene zu einem Verbindungsrand des unteren Randstegabschnitts hin geneigt ist. Damit wird insbesondere eine wirksame Versteifung möglich bei einem palettenartigen Untergestell, dessen Fußrahmen kleiner ausgebildet ist als der Boden des Untergestells, was insbesondere dann der Fall ist, wenn eine Stapelbarkeit der Transport- und Lagerbehälter gegeben sein soll, so dass bei übereinander gestapelter Anordnung der untere Rand der Eckfüße nicht nur zur Verbindung mit dem Fußrahmen dient, sondern gleichzeitig auch zur Abstützung auf einem Oberrand des Außenmantels eines unteren Transport- und Lagerbehälters. Bei einer derartigen Stapelanordnung befindet sich dann der Fußrahmen des oberen Transport- und Lagerbehälters innerhalb einer durch den Oberrand des Außenmantels des unteren Transport- und Lagerbehälters umschlossenen Fläche.A further stiffening of the undercarriage can be achieved in that in the front wall of the corner feet stiffening beads are formed, which extend between the upper edge land portion and the lower edge land portion and having a bead bottom, opposite to a front plane defined by the front wall to a connecting edge of the lower edge land portion is inclined. Thus, in particular an effective stiffening is possible in a pallet-like underframe whose foot frame is smaller than the bottom of the underframe, which is particularly the case when a stackability of the transport and storage containers be given should, so that when stacked arrangement of the lower edge of the corner feet not only for connection to the foot frame, but also for support on an upper edge of the outer shell of a lower transport and storage container. In such a stack arrangement, the foot frame of the upper transport and storage container is then located within a surface enclosed by the upper edge of the outer casing of the lower transport and storage container.

Zur definierten Relativanordnung übereinander gestapelter Transportund Lagerbehälter erweist es sich auch als besonders vorteilhaft, wenn am unteren Randstegabschnitt zwischen dem Umfangsrand der Frontwandung und dem Verbindungsrand Anschlaglaschen angeordnet sind, die durch ihren Abstand vom Umfangsrand einen Auflagerrand zur Abstützung auf einem Außenmantel eines unteren Transport- und Lagerbehälters definieren. Dabei ermöglichen die Anschlaglaschen eine quasi zentrierte Anordnung des oberen Transport- und Lagerbehälters gegenüber dem unteren Transport- und Lagerbehälter, derart, dass zwischen dem Fußrahmen des oberen Transport- und Lagerbehälters und dem Oberrand des Außenmantels des unteren Transport- und Lagerbehälters ein zwischen dem Fußrahmen und dem Oberrand umlaufend ausgebildeter definierter Abstand erzeugt wird, so dass ein unerwünschtes Verkanten der Transport- und Lagerbehälter bei einer Stapelanordnung vermieden und damit sowohl die Herstellung einer Stapelanordnung als auch die Auflösung einer Stapelanordnung mit Trennung der aufeinander gestapelten Transport- und Lagerbehälter voneinander leichter ermöglicht wird und Entstehen entsprechender Gefahrsituationen vermieden werden kann.For defined relative arrangement stacked transport and storage containers, it proves to be particularly advantageous if at the lower edge land portion between the peripheral edge of the front wall and the connecting edge stop tabs are arranged by their distance from the peripheral edge a support edge for support on an outer shell of a lower transport and storage container define. The stop tabs allow a quasi-centered arrangement of the upper transport and storage container relative to the lower transport and storage container, such that between the foot frame of the upper transport and storage container and the upper edge of the outer shell of the lower transport and storage container a between the foot frame and the upper edge circumferentially trained defined distance is generated so that an undesirable tilting of the transport and storage containers avoided in a stacking arrangement and thus both the production of a stacking arrangement and the resolution of a stacking arrangement with separation of the stacked transport and storage containers from each other easier and Emergence of appropriate danger situations can be avoided.

Zur Herstellung eines Fußes für ein palettenartiges Untergestell für einen Transport- und Lagerbehälter für Flüssigkeiten erfolgt in einem ersten Verfahrensschritt die Umformung eines ebenen Blechzuschnitts in einem Tiefziehvorgang derart, dass ein Eckfußvorformling ausgebildet wird mit zwei seitlich einer Mittelachse einer Bodenwandung ausgebildeten Napfteilen, wobei die Frontwandung aus zwei gleichsinnig gekrümmten Mantelsegmenten zusammengesetzt ist, die im Bereich der Mittelachse ineinander übergehen und die Napfteile am Umfangsrand der Bodenwandung jeweils einen aus einem oberen Randsteg, einem seitlichen Randstegabschnitt und einem unteren Randstegabschnitt kontinuierlich ausgebildeten, im Wesentlichen rechtwinklig zur Bodenwandung angeordneten Randsteg aufweisen.To produce a foot for a pallet-like undercarriage for a transport and storage container for liquids in a first process step, the forming of a flat sheet metal blank in a deep drawing process such that a Eckfußvorformling is formed with two side of a central axis of a bottom wall formed Cupfteilen, the front wall of two in the same direction curved Sheath segments is assembled, which merge into one another in the region of the central axis and the cup portions at the peripheral edge of the bottom wall each have an edge web continuously formed from an upper edge web, a lateral edge web portion and a lower edge web portion, arranged substantially at right angles to the bottom wall.

Erfindungsgemäß erfolgt in einem nachfolgenden Verfahrensschritt bei der Herstellung des Eckfußes ein Verschwenken der Mantelsegmente um die Mittelachse gegeneinander, derart, dass die Mantelsegmente eine Frontwandung mit im Wesentlichen kontinuierlichem Krümmungsradius ausbilden.According to the invention, in a subsequent method step during the production of the corner base, the casing segments are pivoted about the central axis relative to one another, such that the casing segments form a front wall with a substantially continuous radius of curvature.

Nachfolgend wird eine bevorzugte Ausführungsform eines palettenartigen Untergestells für Transport- und Lagerbehälter anhand der Zeichnung näher erläutert.Hereinafter, a preferred embodiment of a pallet-like undercarriage for transport and storage containers will be explained with reference to the drawing.

Fig. 1 zeigt einen als Ein- und Mehrwegbehälter verwendbaren Transport- und Lagerbehälter 10 für Flüssigkeiten mit einem Innenbehälter 11 aus Kunststoff, der einen mit einem Deckel 12 verschließbaren Einfüllstutzen 13 im oberen Behälterboden 14 und einen Entleerstutzen 15 im Bereich eines unteren Behälterbodens 16 zum Anschluss einer Entnahmearmatur 17 ausgestattet ist. Der Innenbehälter 11 ist austauschbar in einem Außenmantel 18 aus sich kreuzenden waagerechten und senkrechten Gitterstäben 19, 20 aus Metall aufgenommen, der ebenso wie der Innenbehälter 11 auf einem palettenartigen Untergestell 21 angeordnet ist. Fig. 1 shows a usable as disposable and reusable container transport and storage container 10 for liquids with an inner container 11 made of plastic, which closes a closable with a cover 12 filler 13 in the upper container bottom 14 and a discharge nozzle 15 in the region of a lower container bottom 16 for connecting a removal fitting 17th Is provided. The inner container 11 is exchangeably received in an outer shell 18 of intersecting horizontal and vertical bars 19, 20 made of metal, which is arranged as well as the inner container 11 on a pallet-like base 21.

Das Untergestell 21 weist einen Boden 22 zum Abstützen des Innenbehälters 11 sowie Eckfüße 23 und Mittelfüße 24 auf, die auf einem Fußrahmen 25 angebracht sind und an denen der Boden 22 sowie der Außenmantel 18 des Innenbehälters 11 befestigt sind.The base 21 has a bottom 22 for supporting the inner container 11 and corner feet 23 and middle feet 24 which are mounted on a base frame 25 and to which the bottom 22 and the outer shell 18 of the inner container 11 are attached.

Wie sich aus einer Zusammenschau der Fig. 2 und 3 ergibt, weist der Eckfuß 23 eine Frontwandung 26 auf, die im Wesentlichen entsprechend einem Eckradius einer Rahmenecke 27 des Fußrahmens 25 gekrümmt ist und an ihrem Umfangsrand 28 in einen zum Innenbereich des Fußrahmens 25 hin abgewinkelten Randsteg 29 übergeht, der einen unteren Randstegabschnitt 30 und einen oberen Randstegabschnitt 31 aufweist. Der untere Randstegabschnitt 30 dient zur Verbindung mit dem Fußrahmen 25. Der obere Randstegabschnitt 31 dient zur Verbindung mit einem Unterrand 32 des Außenmantels 18, derart, dass ein Umfangsrand 33 des Bodens 22 zwischen dem oberen Randstegabschnitt 31 ( Fig. 3 ) und dem Unterrand 32 des Außenmantels 18 aufgenommen wird.As can be seen from a synopsis of FIGS. 2 and 3 results, the Eckfuß 23 has a front wall 26 which is curved substantially corresponding to a corner radius of a frame corner 27 of the Fußrahmens 25 and merges at its peripheral edge 28 in an inner region of the Fußrahmens 25 angled edge web 29, which has a lower edge web portion 30 and a upper edge web portion 31 has. The lower edge web portion 30 is for connection to the foot frame 25. The upper edge web portion 31 is for connection to a lower edge 32 of the outer shell 18, such that a peripheral edge 33 of the bottom 22 between the upper edge web portion 31 ( FIGS. Fig. 3 ) and the lower edge 32 of the outer shell 18 is received.

Fig. 4 zeigt einen Eckfußvorformling 34, der in einem Tiefziehvorgang hergestellt ist und in einem weiteren, nachfolgenden Umformungsvorgang zu dem in Fig. 5 dargestellten Eckfuß 23 umgeformt wird. Der Eckfußvorformling 34 weist einen im Wesentlichen kasten- oder napfförmig ausgebildeten Eckfußkörper 35 auf, mit zwei Napfteilen 36, 37, die über eine gemeinsame Bodenwandung miteinander verbunden sind. Fig. 4 shows a Eckfußvorformling 34, which is produced in a deep drawing process and in a further, subsequent forming process to the in Fig. 5 shown Eckfuß 23 is transformed. The Eckfußvorformling 34 has a substantially box or cup-shaped Eckfußkörper 35, with two Napfteilen 36, 37, which are interconnected via a common bottom wall.

Bei dem Eckfußvorformling 34 ist die Bodenwandung 38 aus zwei Zylindermantelsegmenten 39, 40 der Napfteile 36, 37 gebildet, die im Bereich einer Mittelachse 42 der Bodenwandung 38 ineinander übergehen. Wie ferner Fig. 4 deutlich zeigt, weisen die Napfteile 36, 37 längs des Umfangsrandes der Bodenwandung 38 neben dem unteren Randstegabschnitt 30 und dem oberen Randstegabschnitt 31 eine seitlichen Randstegabschnitt 43 auf, der in Randstegumformbereichen 44 kontinuierlich in den oberen Randstegabschnitt 31 und den unteren Randstegabschnitt 30 übergeht.In the Eckfußvorformling 34, the bottom wall 38 of two cylinder shell segments 39, 40 of the cup portions 36, 37 formed in the region of a central axis 42 of the bottom wall 38 into each other. How further Fig. 4 clearly shows, the cup portions 36, 37 along the peripheral edge of the bottom wall 38 adjacent to the lower edge web portion 30 and the upper edge web portion 31 has a lateral edge web portion 43 which merges in Randstegumformbereichen 44 continuously in the upper edge web portion 31 and the lower edge web portion 30.

Bei dem Eckfußvorformling 34 sind die Randstegumformbereiche 44 als räumliche Eckbereiche der Napfteile 36, 37 ausgebildet, in denen der untere Randstegabschnitt 30, der obere Randstegabschnitt 31 und der angrenzende Bereich der Bodenwandung 38 relativ zueinander entsprechend den Hauptachsenrichtungen des Raumes angeordnet sind. Aufgrund der Herstellung des in Fig. 4 abgebildeten Eckfußvorformlings 34 basierend auf einem ebenen Blechzuschnitt werden die Randstegumformbereiche 44 bei Ausführung des Tiefziehvorgangs gleichzeitig mit den Napfteilen 36, 37 ausgebildet. Der in Fig. 4 dargestellte Eckfußvorformling 34 ist somit Ergebnis eines einzigen Umformvorgangs mit Verwendung eines entsprechend ausgebildeten Stempel- bzw. Tiefziehwerkzeugs.In the Eckfußvorformling 34, the Randstegumformbereiche 44 are formed as spatial corner regions of the Napfteile 36, 37, in which the lower edge land portion 30, the upper edge land portion 31 and the adjacent portion of the bottom wall 38 are arranged relative to each other according to the major axis directions of the room. Due to the production of in Fig. 4 As shown in FIG. 1, the Eckstegformformlings 34 based on a flat sheet metal blank, the Randstegumformbereiche 44 are formed simultaneously with the cup portions 36, 37 in performing the deep drawing operation. The in Fig. 4 Eckfußvorformling 34 shown is thus the result of a single forming operation using a trained stamping or thermoforming tool.

Der in Fig. 5 dargestellte Eckfuß 23 wird ausgehend von dem in Fig. 4 dargestellten Eckfußvorformling 34 dadurch hergestellt, dass in einem weiteren Umformvorgang das Verschwenken der Napfteile 36, 37 gegeneinander um eine im Wesentlichen mit der Mittelachse 42 der Bodenwandung 38 zusammenfallende Schwenkachse erfolgt. Dabei erfolgt das Verschwenken in einem solchen Ausmaß, dass die hier als Zylindermantelsegmente 40, 41 ausgebildeten Bodenteilflächen der Bodenwandung 38 des Eckfußvorformlings 34 die Frontwandung 26 ausbilden, bei der die Zylindermantelsegmente 40, 41 Teilflächen einer Gesamtfläche mit-abgesehen von der Profilierung der Frontwandung durch Sicken oder dergleichen - im Wesentlichen kontinuierlichem Krümmungsradius sind.The in Fig. 5 shown Eckfuß 23 is starting from the in Fig. 4 shown Eckfußvorformling 34 produced by the fact that in a further forming operation, the pivoting of the cup portions 36, 37 against each other takes place about a substantially coincident with the central axis 42 of the bottom wall 38 pivot axis. In this case, the pivoting takes place to such an extent that the bottom part surfaces of the bottom wall 38 of the corner foot preform 34 designed here as cylinder jacket segments 40, 41 form the front wall 26, in which the cylinder jacket segments 40, 41 also cover partial surfaces of a total area from the profiling of the front wall by beads or the like - are substantially continuous radius of curvature.

Insbesondere die Fig. 2 und 3 zeigen, dass die Frontwandung 26 mit Versteifungssicken 45, 46 versehen, die sich zwischen dem oberen Randstegabschnitt 31 und dem unteren Randstegabschnitt 30 erstrecken und einen Sickenboden 47 aufweisen, der gegenüber einer durch die Frontwandung 26 definierten Frontebene zu einem in Fig. 5 dargestellten Verbindungsrand 48 des unteren Randstegabschnitts 30 hin geneigt ist. Der Verbindungsrand 48 weist im Falle des vorliegenden Ausführungsbeispiels jeweils zwei stegförmige Schweißbuckel 49 auf, die zur Herstellung einer Schweißverbindung mit dem Fußrahmen 25 dienen. Wie insbesondere aus Fig. 2 ersichtlich, wird durch die geneigte Anordnung des Sickenbodens 47 eine von Kippmomenten freie, direkte Kraftübertragung zwischen dem Unterrand 32 des Außenmantels 18 bzw. des Bodens 22 und dem Fußrahmen 25 möglich.especially the FIGS. 2 and 3 show that the front wall 26 is provided with stiffening beads 45, 46 which extend between the upper edge web portion 31 and the lower edge web portion 30 and have a bead bottom 47 which is opposite to a front plane defined by the front wall 26 to a in Fig. 5 shown connecting edge 48 of the lower edge web portion 30 is inclined towards. In the case of the present exemplary embodiment, the connecting edge 48 has two web-shaped welding bosses 49, which serve to produce a welded connection with the foot frame 25. As in particular from Fig. 2 can be seen by the inclined arrangement of the bead bottom 47 a tilting torque-free, direct power transmission between the lower edge 32 of the outer shell 18 and the bottom 22 and the foot frame 25 is possible.

Insbesondere die Fig. 5 und 6 zeigen, dass der Eckfuß 23 an seinem unteren Randstegabschnitt 30 beidseitig der Mittelachse 42 jeweils mit einer Anschlaglasche 50, 51 versehen, die bei einer in Fig. 6 dargestellten Anordnung des Eckfußes 23 in Stapelkonfiguration, also wenn die Eckfüße 23 eines oberen Transport- und Lagerbehälters 10 auf einem Oberrand 53 (siehe Fig. 1 ) des Außenmantels 18 eines unteren Transport- und Lagerbehälters 10 angeordnet sind, einen Auflagerrand 52 des unteren Randstegabschnitts 30 von dem Verbindungsrand 48 des unteren Randstegabschnitts 30, der zur Schweißverbindung mit dem Fußrahmen 25 dient, trennt. Dabei sind die Anschlaglaschen 50, 51 so ausgebildet, dass sie den Abstand zwischen dem Oberrand 53 des Außenmantels 18 des unteren Transport- und Lagerbehälters 10 vom Fußrahmen 25 des in Stapelkonfiguration darauf angeordneten oberen Transport- und Lagerbehälters 10 definieren. Bei einer Anordnung der Anschlaglaschen 50, 51 an allen vier Eckfüßen des Transport- und Lagerbehälters ergibt sich somit ein um den Fußrahmen 25 umlaufender, definierter freier Abstand zwischen dem Fußrahmen 25 des oberen Transport- und Lagerbehälters 10 und dem Oberrand 53 des unteren Transport- und Lagerbehälters 10.especially the FIGS. 5 and 6 show that the Eckfuß 23 at its lower edge web portion 30 on both sides of the central axis 42 each provided with a stop tab 50, 51, which at a in Fig. 6 illustrated arrangement of Eckfußes 23 in stack configuration, so if the corner feet 23 of an upper transport and storage container 10 on an upper edge 53 (see Fig. 1 ) of the outer shell 18 of a lower transport and storage container 10 are arranged, a support edge 52 of the lower edge web portion 30 of the connecting edge 48 of the lower edge web portion 30, which is used for welding to the Fußrahmen 25 separates. In this case, the stop tabs 50, 51 are formed so that they define the distance between the upper edge 53 of the outer shell 18 of the lower transport and storage container 10 from the foot frame 25 of the stacked configuration disposed thereon upper transport and storage container 10. In an arrangement of the stop tabs 50, 51 at all four corner feet of the transport and storage container thus results in a surrounding the foot frame 25, defined free distance between the foot frame 25 of the upper transport and storage container 10 and the upper edge 53 of the lower transport and storage container 10th
