Abstract

For the container transport of bitumen or other substances which require heating (or cooling) as long as they are in the container, a freight container is used which is made up of a substantially cuboid frame consisting of individual angled rails 10...14 with outwardly pointing limbs and shell elements 16...20 inserted between said rails. In their edge regions, the shell elements 16, 17 surround the angled rails 10, 11 and are welded to the free edges of both limbs of these rails. As a result, closed channels 21 of approximately triangular cross-section are produced which lie inside the tank and are connected to one another via pipes 22...24 which pass through the inside of the tank. In this manner, using light profiled elements, a tank is formed which is nevertheless rigid and has an internal linked piping system for conducting a temperature-conditioning medium. <IMAGE>

Description

Ein Frachtcontainer mit den im ersten Teil des Anspruchs 1 angegebenen Merkmalen ist aus DE 18 08 755 C1 bekannt. Derartige Container dienen zum Transport von fließfähigen Gütern und zeichnen sich durch hohes Nutzvolumen innerhalb der vom Rahmen definierten Gesamtabmessungen aus. Durch die Verwendung von gewölbten Schalenelementen, die in den Seiten- und Stirnflächen vorzugsweise um senkrechte Achsen gewölbt sind, wird auch eine brauchbare Festigkeit erzielt.A freight container with the features specified in the first part of claim 1 is known from DE 18 08 755 C1. Such containers are used to transport flowable goods and are characterized by a high usable volume within the overall dimensions defined by the frame. By using curved shell elements, which are preferably curved around vertical axes in the side and end faces, a useful strength is also achieved.

Bitumen, das insbesondere im Straßenbau Einsatz findet, wird bisher in Einzelfässern transportiert. Das Bitumen wird bei Temperaturen von 180 bis 200 °C abgefüllt und erstarrt während des Transports. Am Bestimmungsort werden die Fässer erhitzt, so daß das Bitumen schmilzt und die Fässer entleert werden können.Bitumen, which is used particularly in road construction, has so far been transported in individual drums. The bitumen is filled at temperatures from 180 to 200 ° C and solidifies during transport. The drums are heated at their destination so that the bitumen melts and the drums can be emptied.

Der Erfindung liegt die Aufgabe zugrunde, den bekannten Frachtcontainer so weiterzubilden, daß er sich zum Großtransport von solchen Stoffen eignet, die eine Temperierung (Beheizung oder auch Kühlung) vor der Entleerung und/oder während des Transports erfordern.The invention has for its object to develop the known freight container so that it is suitable for the large transport of such materials that require tempering (heating or cooling) before emptying and / or during transport.

Die erfindungsgemäße Lösung dieser Aufgabe ist im Anspruch 1 gekennzeichnet. Die danach von den Rahmenelementen in Verbindung mit den Containerwand-Schalenelementen gebildeten, innerhalb des Container-Innenraums liegenden und im Querschnitt etwa dreieckigen Kanäle gestatten die Einleitung eines Heiz- oder auch Kühlmediums zur Temperierung des Containerinhalts vor seiner Entnahme, ohne daß zusätzliche, das Taragewicht des Frachtcontainers erhöhende Konstruktionselemente benötigt werden. Durch Verwendung von an sich leichten Winkelschienen und deren Ergänzung durch Randbereiche der Schalenelemente zu geschlossenen Profilen wird gleichzeitig die Eigensteifigkeit des Containerrahmens ohne Gewichtszunahme erhöht.The solution to this problem according to the invention is characterized in claim 1. The channels then formed by the frame elements in connection with the container wall-shell elements, lying inside the container interior and approximately triangular in cross-section, allow the introduction of a heating or cooling medium for tempering the container contents before it is removed, without additional, the tare weight of the Freight container-increasing construction elements are required. By using angle rails which are light in themselves and supplemented by edge areas of the shell elements for closed profiles, the inherent rigidity of the container frame is increased without increasing weight.

In der Praxis wird man mindestens die beiden unteren in Container-Längsrichtung verlaufenden Rahmenelemente in der erfindungsgemäßen Weise als Kanäle zur Leitung eines Temperierungsmediums ausbilden. Es ist aber auch möglich, weitere oder sämtliche der zwölf an den Kanten des insgesamt quaderförmigen Rahmens verlaufenden Rahmenelemente als Kanäle auszubilden.In practice, at least the two lower frame elements running in the longitudinal direction of the container will be designed as channels for guiding a temperature control medium in the manner according to the invention. However, it is also possible to design further or all of the twelve frame elements running on the edges of the overall rectangular frame as channels.

In der Weiterbildung der Erfindung nach Anspruch 2 dienen auch rohrförmige Zuganker, die das Containerinnere durchsetzen, den obigen beiden Zwecken, nämlich sowohl der Leitung eines Heiz- oder Kühlmediums als auch der Versteifung der Rahmenstruktur.In the development of the invention according to claim 2, tubular tie rods which penetrate the interior of the container also serve the above two purposes, namely both the conduction of a heating or cooling medium and the stiffening of the frame structure.

Aus DE 87 10 906 U1 ist es an sich bekannt, derartige rohrförmige Zuganker miteinander sowie mit in der Außenfläche eines Tankmantels verlaufenden rohrförmigen Längsholmen zu einem zusammenhängenden Rohrsystem zur Leitung eines Kühl- oder Heizmediums zu verbinden. Die dort vorgesehenen Längsholme sind aber nur mit etwa der Hälfte ihrer Oberfläche dem Tankinnern zugewandt, während die andere Hälfte ihrer Oberfläche nach außen frei liegt, so daß ein wesentlicher Teil des Heiz- oder Kühlmediums nicht für die Temperierung des Containerinhalts ausgenutzt wird.From DE 87 10 906 U1 it is known per se to connect such tubular tie rods to one another and to tubular longitudinal struts running in the outer surface of a tank jacket to form a coherent pipe system for conducting a cooling or heating medium. The longitudinal spars provided there are only about half of their surface facing the inside of the tank, while the other half of their surface is exposed to the outside, so that a substantial part of the heating or cooling medium is not used for the temperature control of the container contents.

Die Ausgestaltung der Erfindung nach Anspruch 3 führt nicht nur zu einer weiteren Versteifung des Rahmens unter Minderung der in den Längskanten auftretenden Spannungen, sondern auch zu einer Vergrößerung der für den Wärmeaustausch mit dem Containerinhalt verfügbaren Oberfläche. Außerdem bilden die nach Anspruch 3 vorgesehenen Verbindungsstücke schwallhemmende Elemente.The embodiment of the invention according to claim 3 not only leads to a further stiffening of the frame while reducing the stresses occurring in the longitudinal edges, but also to an increase in the surface area available for heat exchange with the container contents. In addition, the connectors provided according to claim 3 form anti-surge elements.

Die Merkmale der Ansprüche 4 und 5 dienen einer einfachen Fertigung bei hoher Festigkeit des Containers. Eine weitere Erhöhung der Festigkeit wird durch die in Anspruch 6 angegebenen äußeren Eckstützen erreicht, die nach Anspruch 7 gleichzeitig als Halterungen für eine äußere Containerisolierung herangezogen werden können.The features of claims 4 and 5 serve for simple manufacture with high strength of the container. A further increase in strength is achieved by the outer corner supports specified in claim 6, which can also be used according to claim 7 as holders for outer container insulation.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnungen näher erläutert, in denen

An embodiment of the invention is shown below explained in more detail with reference to the drawings, in which
Figure 1
a cross section through a cargo container in a plane perpendicular to the longitudinal axis and
Figure 2
illustrates a partial horizontal section in a plane containing the longitudinal axis of the container.

Gemäß den Zeichnungen ist der Containerrahmen aus zwei unteren Längsholmen 10, zwei oberen Längsholmen 11, zwei unteren Querholmen 12, zwei oberen Querholmen 13 und vier Eckelementen 14 aufgebaut. Die Enden der Querholme 12, 13 und der Eckelemente 14 sind mit an allen acht Ecken vorgesehenen Eckbeschlägen 15 verbunden. Die Längsholme 10, 11 sind, wie aus Figur 1 ersichtlich, mit den jeweiligen Eckelementen 14 an Stellen verbunden, die gegenüber den Eckbeschlägen 15 nach innen (d.h. nach oben bzw. nach unten) versetzt sind.According to the drawings, the container frame is constructed from two lower longitudinal spars 10, two upper longitudinal spars 11, two lower transverse spars 12, two upper transverse spars 13 and four corner elements 14. The ends of the cross bars 12, 13 and the corner elements 14 are connected to corner fittings 15 provided at all eight corners. The longitudinal bars 10, 11 are, as can be seen from FIG. 1, connected to the respective corner elements 14 at locations which are offset inwards (i.e. upwards or downwards) with respect to the corner fittings 15.

Der Containermantel wird von nach außen gewölbten Schalenelementen gebildet, die zwischen die Rahmenelemente eingefügt sind. Wie aus Figur 1 ersichtlich, wird die Containerbreite von einer einzelnen Bodenschale 16 und einer einzelnen Deckschale 17 überspannt. Die Bodenschale 16 und die Deckschale 17 sind um zur Container-Längsachse parallele Achsen gekrümmt. Je nach Containerlänge sind die Bodenschale 16 und die Deckschale 17 in Längsrichtung aus mehreren Blechschüssen zusammengesetzt, wobei zwischen einzelne Schüsse Rahmen-Querstreben eingefügt sein können, wie dies auch bei dem Container nach DE 18 08 755 C1 der Fall ist.The container jacket is formed by shell elements which are curved outwards and are inserted between the frame elements. As can be seen from FIG. 1, the container width is spanned by a single bottom shell 16 and a single cover shell 17. The bottom shell 16 and the cover shell 17 are curved about axes parallel to the longitudinal axis of the container. Depending on the length of the container, the bottom shell 16 and the cover shell 17 are composed of a plurality of sheet metal sections in the longitudinal direction, frame cross braces being able to be inserted between individual sections, as is also the case with the container according to DE 18 08 755 C1.

Aus Figur 2 geht ferner hervor, daß auch die die Container-Seitenwände bildenden Seitenschalen 19, 20 um senkrechte Achsen gewölbt sind. Je nach Containerlänge sind auch hier zwei oder mehr Schalen in Längsrichtung erforderlich; auch dies entspricht insoweit dem Aufbau des Containers nach DE 18 08 755 C1. Die in Figur 2 unten dargestellte Seitenschale 20 weist dabei eine durchgehende, nach außen konvexe Krümmung auf, während die in Figur 2 oben gezeigt Seitenschale 19 in ihren Randbereichen mit konkaven Gegenkrümmungen versehen ist.FIG. 2 also shows that the side shells 19, 20 forming the container side walls are curved around vertical axes. Depending on the container length, two or more shells in the longitudinal direction are also required here; This also corresponds to the construction of the container according to DE 18 08 755 C1. The side shell 20 shown in FIG. 2 below has a continuous, outwardly convex curvature, while the side shell 19 shown in FIG. 2 above is provided with concave counter-curvatures in its edge regions.

Sämtliche zwölf Rahmenelemente 10...14 bestehen aus L-Profil- oder Winkelschienen, die mit ihren beiden Schenkeln jeweils nach außen weisen. Gemäß Figur 1 sind die horizontalen Schenkel der unteren und oberen Längsholme 10, 11 etwa doppelt so breit wie ihre senkrechten Schenkel. Ferner ist die Breite der senkrechten Schenkel der unteren und oberen Querholme 12, 13 so gewählt, daß sie der Wölbungshöhe der Boden- bzw. Deckschale 16, 17 mindestens entspricht. Die Schalen 16, 17, lassen sich daher mit den senkrechten Schenkeln der Querholme 12, 13 stumpf verschweißen.All twelve frame elements 10 ... 14 consist of L-profile or angle rails, with their two legs each point outwards. According to Figure 1, the horizontal legs of the lower and upper longitudinal spars 10, 11 are approximately twice as wide as their vertical legs. Furthermore, the width of the vertical legs of the lower and upper cross members 12, 13 is selected so that it at least corresponds to the curvature height of the bottom or top shell 16, 17. The shells 16, 17 can therefore be butt-welded to the vertical legs of the cross bars 12, 13.

Das Maß, um das die Längsholme 10, 11 gegenüber den Containeraußenmaßen einwärts versetzt sind, ist ferner so gewählt, daß sich die Bodenschale 16 und die Deckschale 17 bei durchgehender Wölbung in ihren Randbereichen mit beiden freien Kanten der Längsholme 10, 11 verschweißen lassen. Dadurch entstehen in Container-Längsrichtung insgesamt vier geschlossene Kanäle 21 mit im wesentlichen dreieckigem Querschnitt, die fast vollständig innerhalb des von sämtlichen Schalenelementen gebildeten Containerinnenraums liegen.The extent to which the longitudinal spars 10, 11 are offset inwards with respect to the container outer dimensions is also selected such that the bottom shell 16 and the cover shell 17 can be welded to both free edges of the longitudinal spars 10, 11 in their edge regions with continuous curvature. This results in a total of four closed channels 21 with a substantially triangular cross section in the longitudinal direction of the container, which lie almost completely within the container interior formed by all the shell elements.

In Figur 1 ist ferner gezeigt, daß die senkrechten Schenkel der beiden unteren Längsholme 10 über den Containerinnenraum horizontal durchsetzende Rohre 22 miteinander verbunden sind. Die Längsholme 10 sind in den Bereichen, an denen die Rohre 22 angeschweißt sind, mit Bohrungen versehen, so daß die Kanäle 21 über die Rohre 22 miteinander kommunizieren.In FIG. 1 it is also shown that the vertical legs of the two lower longitudinal spars 10 are connected to one another by tubes 22 which pass horizontally through the container interior. The longitudinal bars 10 are provided with bores in the areas to which the tubes 22 are welded, so that the channels 21 communicate with one another via the tubes 22.

Ein weiteres horizontales Verbindungsrohr 23 ist im linken oberen Teil der Figur 1 teilweise dargestellt und verbindet die senkrechten Schenkel der oberen Längsholme 11 miteinander. Ferner ist im linken Teil der Figur 1 ein senkrechtes Rohr 24 dargestellt, das die horizontalen Schenkel des linken unteren Längsholms 10 und des linken oberen Längsholms 11 miteinander verbindet. Auch dieses Rohr 24 verläuft innerhalb der Seitenschale 19 bzw. 20 und befindet sich damit völlig innerhalb des Container-Innenraums.Another horizontal connecting pipe 23 is partially shown in the upper left part of FIG. 1 and connects the vertical legs of the upper longitudinal spars 11 to one another. Furthermore, a vertical tube 24 is shown in the left part of FIG. 1, which connects the horizontal legs of the lower left longitudinal spar 10 and the upper left longitudinal spar 11 to one another. This tube 24 also runs within the side shell 19 and 20 and is thus completely within the container interior.

Gemäß Figur 2 ist bei den Eckelementen 14 der in Container-Längsrichtung weisende Schenkel etwa halb so breit wie der in Querrichtung verlaufende Schenkel. Auf diese Weise läßt sich auch die Stirnschale 18 bei durchgehender Wölbung in ihren Randbereichen mit den senkrechten freien Kanten beider Schenkel der Eckelemente 14 verschweißen, so daß auch hier Kanäle 21 mit geschlossenem, im wesentlichen dreieckigem Querschnitt entstehen. Die Stirnschale 18 ist an ihrer oberen und an ihrer unteren Kante an den horizontalen Schenkel der Querholme 13 bzw. 12 angeschweißt.According to FIG. 2, in the corner elements 14 the leg pointing in the longitudinal direction of the container is approximately half as wide as the leg extending in the transverse direction. In this way, the front shell 18 can be with continuous curvature in its edge areas with the vertical free edges of both Weld the legs of the corner elements 14 so that channels 21 with a closed, essentially triangular cross-section are also formed here. The front shell 18 is welded at its upper and at its lower edge to the horizontal leg of the cross bars 13 and 12 respectively.

In dem gemäß Figur 1 linken unteren Bereich ist ein zwischen das horizontale Rohr 22 und das vertikale Rohr 24 eingefügtes diagonales Verbindungsblech 25 gezeigt. Derartige Verbindungsstücke 25, die auch als Rohre ausgebildet sein können, können auch in den anderen vier Eckbereichen sowie an mehreren Stellen in Containerlängsrichtung vorgesehen sein.1, a diagonal connecting plate 25 inserted between the horizontal tube 22 and the vertical tube 24 is shown. Such connecting pieces 25, which can also be designed as tubes, can also be provided in the other four corner areas and at several locations in the longitudinal direction of the container.

Die beschriebene, in Figur 2 gezeigte ungleiche Schenkellänge der Eckelemente 14 läßt im äußersten Eckbereich Platz für rohrförmige Eckstützen 26, deren jede einen unteren Eckbeschlag 15 mit einem oberen Eckbeschlag 15 verbindet. Dadurch erfährt die Rahmenstruktur eine weitere Versteifung. Gleichzeitig können die nach außen runden Eckstützen 26 zum Umwickeln des Tanks mit einer (nicht gezeigten) Isolierhülle dienen.The unequal leg length of the corner elements 14 described in FIG. 2 leaves space in the outermost corner area for tubular corner supports 26, each of which connects a lower corner fitting 15 to an upper corner fitting 15. As a result, the frame structure is further stiffened. At the same time, the outwardly round corner supports 26 can be used to wrap the tank with an insulating sleeve (not shown).

Wie erläutert, bilden die in den Längsholmen 10, 11, in den Eckelementen 14 sowie möglicherweise auch in den Querholmen 12, 13 ausgebildeten Kanäle 21 ein über die Verbindungsrohre 22...24 zusammenhängendes Rohrleitungssystem zur Führung eines Temperierungsmediums. An einer (nicht gezeigten) Stelle ist dieses Rohrleitungssystem mit Ein- und Auslaß zum Anschluß an eine externe Versorgungseinrichtung mit Umwälzpumpe und Heiz- bzw. Kühlaggregat angeschlossen. Dient der Frachtcontainer beispielsweise zum Transport von Bitumen, so wird der nach Ankunft am Bestimmungsort an ein Heizsystem angeschlossen, das Thermalöl durch das Rohrleitungssystem des Containers schickt. Um eine gezielte Zwangsdurchströmung zu erreichen, können in den verschiedenen Verbindungsbereichen der Kanäle 21 mit den Rohren 22...24 Strömungs-Führungseinrichtungen vorgesehen sein.As explained, the channels 21 formed in the longitudinal spars 10, 11, in the corner elements 14 and possibly also in the transverse spars 12, 13 form a piping system connected via the connecting tubes 22... 24 for guiding a temperature control medium. At one point (not shown), this piping system with inlet and outlet is connected for connection to an external supply device with a circulating pump and heating or cooling unit. For example, if the freight container is used to transport bitumen, it is connected to a heating system when it arrives at its destination, which sends thermal oil through the pipe system of the container. In order to achieve a targeted forced flow, flow guide devices can be provided in the different connection areas of the channels 21 with the tubes 22 ... 24.
