Definitions
- a pressure-resistant tank of the type specified in the preamble of claim 1 is known from DE-C-2 253 235.
- this container designed as a tank container, four partially circular cylindrical jacket shells forming the tank jacket are inserted between two end frames of the container. Between these end frames also run outside the tank jacket, four U or L-section beams, each of which projects with a flange into the bead between two abutting jacket shells.
- the ends of tie rods which run through the interior of the tank and penetrate the tank jacket in the bead area, are welded to these flanges of opposing profile beams.
- the tie rods in the interior of the tank are designed to be tubular.
- the known tank requires correspondingly heavy front frames to fix the massive profile beams and therefore has a high weight. Furthermore, a relatively large number of tie rods is provided, which not only further increase the weight of the tank, but also mean a high manufacturing effort and considerably hinder the cleaning of the tank interior.
- a tank container is also known, the upper and lower arched jacket shells of which are attached to the upper and lower tubular longitudinal spars extending in the longitudinal direction of the container and which are connected to one another via a pulling wall dividing the entire container into two chambers.
- This container is also expensive to manufacture and has a high tare weight due to the continuous draw wall. Because of the partition, cleaning the interior of the container is also complex here.
- the invention has for its object to provide a tank which has the lowest possible weight with high compressive strength, is easy to clean and easy to manufacture.
- the solution to this problem according to the invention is characterized in claim 1.
- the tubular longitudinal spars provided thereafter, each inserted between two adjacent jacket shells, need not be too heavy, since they are reinforced in the fastening areas of the tie rods by inserted sections of a further tube. Because of these reinforcements in the tubular longitudinal spars, a few tie rods are sufficient. For a given compressive strength, the forces occurring in the few tie rods can be easily introduced into the longitudinal spars without causing undue stress peaks or bending. A small number of tie rods are favorable from the standpoint of manufacturing, tank empty weight and cleaning the inside of the tank.
- the embodiments of the invention according to claims 3 and 4 are useful in terms of the achievable strength of the tie rods themselves and their connection to the longitudinal spars.
- the measure according to claim 5 serves to prevent a relative movement between the tubular longitudinal spar and the pipe section inserted into it, in order to bring the reinforcing effect of the pipe sections to full advantage.
- the development of the invention according to claim 6 is favorable with regard to the cleaning of the tank interior and also allows the tank to be closed at each of these points by an attachment on the tank bottom; alternatively, the ends of the tubular longitudinal spars can be closed by additional sheet metal pieces which run as pulling and doubling elements over part of the tank bottom.
- the tank is made of stainless steel or another high-quality material
- the reinforcement pipe sections lying inside the longitudinal spars are made of less noble, but high-strength material.
- the jacket shells can be in one piece in the longitudinal direction and do not, as previously, need to be assembled from several individual transverse wefts. This results in an overall shorter weld seam length and easier assembly.
- the further training according to claim 9 has the advantage that no additional weight-increasing measures on the tank are required for any cooling or heating apart from the external feed lines and connections.
- the tank is composed of four parallel, partially circular cylindrical jacket shells 10 and two tank bottoms 11 on the front side.
- the tank has a cloverleaf-like shape in cross section, the axes of the four jacket shells 10 defining the corners of a rectangle.
- the tank is connected to two container end frames 14 via lower saddle pieces 12 and upper support elements 13.
- a tubular longitudinal spar 15 runs in the longitudinal direction of the tank, which, as can be seen particularly clearly from FIG. 1 above, is chamfered at its ends at approximately 45 ° or flatter such that its smallest length extends to the inside of the tank is facing and its greatest length ends at the point where the tank bottom 11 in question begins.
- four gusset-shaped sheet metal pieces 16 are canted at the aforementioned angle of approximately 45 ° or flatter, which engage in the respective bead area between two jacket shells 10 and at the same time close the part of the oblique end face of the tubular longitudinal strut 15 located outside the jacket shells 10.
- the tank jacket is also surrounded by two reinforcement rings 17 which follow the approximately cloverleaf-like contour of the tank shown in FIG.
- Tubular tie rods 18, 19 penetrating the tank interior are also provided perpendicular to the tank axis.
- a vertical tie rod 18 and a horizontal tie rod 19 are provided directly next to one another so that they touch one another in the area of the intersection and can be connected to one another for further stiffening.
- With a tank length of 20 feet (6058 mm) a total of four tie rods 18, 19 are provided.
- Each tie rod 18, 19 completely penetrates the respective longitudinal spar 15 at its ends and protrudes a short distance the outside of it.
- the longitudinal spar 15 is reinforced by an inserted pipe section 20.
- the pipe sections 20 are cut obliquely at both ends such that the greatest length of each pipe section 20 faces the interior of the tank. This results in a gradual transfer of tension from the reinforced region of the longitudinal strut 15 to the non-reinforced region, the inner longest tongue-like end regions of the tube sections 20 having a certain elasticity.
- the end of the tie rod 18 is welded both to the longitudinal beam 15 and to the pipe section 20 both at the penetration point located inside the tank and at the outside of the tank. Since the reinforcing effect of the tube section 20 is only fully achieved if relative movements between the latter and the tubular longitudinal spar 15 are excluded, these two components are directly connected to one another via welds which are made along the edges of recesses 21 provided in the tubular spar 15.
- the two jacket shells 10 are each welded to the tubular beam 15.
- the pipe sections 20 that do not come into contact with the cargo are made of high-strength structural or fine-grained steel.
- a further saving in high-quality tank material can be achieved in that the continuous longitudinal spar 15 is also made from less high-quality tank material and, according to FIG. 4, is surrounded in its area lying inside the tank by a partially cylindrical sleeve 22 made of tank material, which has the longitudinal spar on its longitudinal edges 15 is welded and to which the jacket shells 10 attach.
- the tubular longitudinal spars 15 and tie rods 18, 19 can be used to conduct a cooling or heating medium, which is supplied via (not shown) external leads and connections.
- a cooling or heating medium which is supplied via (not shown) external leads and connections.

Description
Ein druckfester Tank der im Oberbegriff des Anspruchs 1 angegebenen Gattung ist aus DE-C-2 253 235 bekannt. Bei diesem als Tankcontainer gestalteten Behälter sind vier, den Tankmantel bildende teilkreiszylindrische Mantelschalen zwischen zwei Stirnrahmen des Containers eingefügt. Zwischen diesen Stirnrahmen verlaufen ferner außerhalb des Tankmantels vier U- oder L-Profilträger, die jeweils mit einem Flansch in die Sicke zwischen zwei aneinanderstoßenden Mantelschalen hineinragen. An diesen Flanschen von gegenüberliegenden Profilträgern sind die Enden von Zugankern angeschweißt, die durch das Tankinnere verlaufen und den Tankmantel im Sickenbereich durchsetzen. Zur Erzielung größerer Steifigkeit ist daran gedacht, die Zuganker im Tankinnern rohrförmig zu gestalten.A pressure-resistant tank of the type specified in the preamble of claim 1 is known from DE-C-2 253 235. In the case of this container designed as a tank container, four partially circular cylindrical jacket shells forming the tank jacket are inserted between two end frames of the container. Between these end frames also run outside the tank jacket, four U or L-section beams, each of which projects with a flange into the bead between two abutting jacket shells. The ends of tie rods, which run through the interior of the tank and penetrate the tank jacket in the bead area, are welded to these flanges of opposing profile beams. To achieve greater rigidity, the tie rods in the interior of the tank are designed to be tubular.
Der bekannte Tank erfordert zur Festlegung der massiven Profilträger entsprechend schwere Stirnrahmen und weist daher ein hohes Eigengewicht auf. Ferner ist eine verhältnismäßig große Anzahl an Zugankern vorgesehen, die nicht nur das Eigengewicht des Tanks weiter erhöhen, sondern auch einen hohen Herstellungsaufwand bedeuten und die Reinigung des Tankinnenraums erheblich behindern.The known tank requires correspondingly heavy front frames to fix the massive profile beams and therefore has a high weight. Furthermore, a relatively large number of tie rods is provided, which not only further increase the weight of the tank, but also mean a high manufacturing effort and considerably hinder the cleaning of the tank interior.
Aus DE-C-2 007 142 ist ferner ein Tankcontainer bekannt, dessen obere und untere gewölbte Mantelschalen an in Behälterlängsrichtung verlaufenden oberen und unteren rohrförmigen Längsholmen ansetzen, die über eine den gesamten Behälter in zwei Kammern unterteilende Zugwand miteinander verbunden sind. Auch dieser Behälter ist in der Herstellung teuer und weist aufgrund der durchgehenden Zugwand hohes Taragewicht auf. Wegen der Trennwand ist auch hier die Reinigung des Behälterinnenraums aufwendig.From DE-C-2 007 142 a tank container is also known, the upper and lower arched jacket shells of which are attached to the upper and lower tubular longitudinal spars extending in the longitudinal direction of the container and which are connected to one another via a pulling wall dividing the entire container into two chambers. This container is also expensive to manufacture and has a high tare weight due to the continuous draw wall. Because of the partition, cleaning the interior of the container is also complex here.
Der Erfindung liegt die Aufgabe zugrunde, einen Tank anzugeben, der bei hoher Druckfestigkeit möglichst geringes Eigengewicht aufweist, mühelos zu reinigen und leicht herzustellen ist.The invention has for its object to provide a tank which has the lowest possible weight with high compressive strength, is easy to clean and easy to manufacture.
Die erfindungsgemäße Lösung dieser Aufgabe ist im Anspruch 1 gekennzeichnet. Die danach vorgesehenen, jeweils zwischen zwei benachbarte Mantelschalen eingefügten rohrförmigen Längsholme brauchen nicht allzu schwer sein, da sie in den Befestigungsbereichen der Zuganker durch eingefügte Abschnitte eines weiteren Rohrs verstärkt sind. Wegen dieser Verstärkungen in den rohrförmigen Längsholmen kommt man mit wenigen Zugankern aus. Bei gegebener Druckfestigkeit können die in den wenigen Zugankern auftretenden Kräfte problemlos in die Längsholme eingeleitet werden, ohne daß unzulässige Spannungsspitzen oder Verbiegungen auftreten. Eine geringe Anzahl von Zugankern ist vom Standpunkt der Fertigung, des Tankleergewichts und der Reinigung des Tankinnern günstig.The solution to this problem according to the invention is characterized in claim 1. The tubular longitudinal spars provided thereafter, each inserted between two adjacent jacket shells, need not be too heavy, since they are reinforced in the fastening areas of the tie rods by inserted sections of a further tube. Because of these reinforcements in the tubular longitudinal spars, a few tie rods are sufficient. For a given compressive strength, the forces occurring in the few tie rods can be easily introduced into the longitudinal spars without causing undue stress peaks or bending. A small number of tie rods are favorable from the standpoint of manufacturing, tank empty weight and cleaning the inside of the tank.
Aus DE-A-3 517 289 ist es zwar bekannt, bei einem Transportbehälter Verbindungselemente in Sacklöcher von Verstärkungselementen einzusetzen, wobei die beispielsweise mit einem U-Profil versehenen Verstärkungselemente durch eine entsprechende Flacheiseneinlage verstärkt sind. Bei dem aus dieser Schrift bekannten Transportbehälter handelt es sich jedoch nicht um einen druckfesten Tank, der bei der Erfindung vorausgesetzten Gattung; auch das erfindungsgemäße Merkmal in einen rohrförmig gestalteten Längsholm an der Verbindungsstelle zum Zuganker einen Innenrohrabschnitt einzufügen, ist bei diesem Stand der Technik nicht verwirklicht.From DE-A-3 517 289 it is known to use connecting elements in the blind holes of reinforcing elements in a transport container, the reinforcing elements provided, for example, with a U-profile being reinforced by a corresponding flat iron insert. In the transport container known from this document, however, it is not a pressure-resistant tank, the type presupposed in the invention; even the feature according to the invention to insert an inner tube section into a tubular longitudinal spar at the connection point to the tie rod is not realized in this prior art.
Die gleichen Überlegungen gelten hinsichtlich des aus CH-A-431 385 bekannten Rechtecktanks, bei dem rohrförmige Zuganker in konventioneller Weise über auf die Außenseite der ebenen Tankwände aufgeschweißte Verstärkungsscheiben befestigt sind.The same considerations apply to the rectangular tank known from CH-A-431 385, in which tubular tie rods are fastened in a conventional manner via reinforcing disks welded onto the outside of the flat tank walls.
Die Weiterbildung der Erfindung nach Anspruch 2 ergibt den Vorteil, daß die Verstärkungsbereiche der Rohrabschnitte nicht abrupt aufhören. Vielmehr bewirken die durch die Abschrägung entstehenden, dem Tank zugewandten federnden Enden der Rohrabschnitte einen allmählichen Übergang.The development of the invention according to claim 2 gives the advantage that the reinforcement areas of the pipe sections do not stop abruptly. Rather, the resilient ends of the pipe sections which are created by the bevel and face the tank bring about a gradual transition.
Die Ausgestaltungen der Erfindung nach den Ansprüchen 3 und 4 sind im Hinblick auf die erzielbare Festigkeit der Zuganker selbst sowie ihrer Verbindung mit den Längsholmen zweckmäßig. Die Maßnahme nach Anspruch 5 dient dazu, eine Relativbewegung zwischen dem rohrförmigen Längsholm und dem in ihn eingefügten Rohrabschnitt zu verhindern, um den verstärkenden Effekt der Rohrabschnitte voll zur Geltung zu bringen.The embodiments of the invention according to claims 3 and 4 are useful in terms of the achievable strength of the tie rods themselves and their connection to the longitudinal spars. The measure according to claim 5 serves to prevent a relative movement between the tubular longitudinal spar and the pipe section inserted into it, in order to bring the reinforcing effect of the pipe sections to full advantage.
Die Weiterbildung der Erfindung nach Anspruch 6 ist im Hinblick auf die Reinigung des Tankinnenraums günstig und gestattet es ferner, den Tank an diesen Stellen durch jeweils einen Ansatz am Tankboden zu verschließen; alternativ können die Enden der rohrförmigen Längsholme durch zusätzliche Blechstücke verschlossen werden, die als Zug- und Dopplerelemente über einen Teil des Tankbodens verlaufen.The development of the invention according to claim 6 is favorable with regard to the cleaning of the tank interior and also allows the tank to be closed at each of these points by an attachment on the tank bottom; alternatively, the ends of the tubular longitudinal spars can be closed by additional sheet metal pieces which run as pulling and doubling elements over part of the tank bottom.
Ist der Tank aus Edelstahl oder einem sonstigen hochwertigen Werkstoff gefertigt, so kann es gemäß Anspruch 7 zweckmäßig sein, die rohrförmigen Längsholme nicht insgesamt aus dem Tankwerkstoff zu fertigen, sondern nur in ihrem im Tankinnern liegenden Bereich mit aus Tankwerkstoff bestehenden teilzylindrischen Hülsen zu umkleiden. In jedem Fall sind die im Innern der Längsholme liegenden Verstärkungs-Rohrabschnitte aus weniger edlem, dafür aber hohe Festigkeitseigenschaften aufweisendem Werkstoff gefertigt.If the tank is made of stainless steel or another high-quality material, then it may be expedient, according to claim 7, not to manufacture the tubular longitudinal spars entirely from the tank material, but only to clad them in their area inside the tank with partially cylindrical sleeves made of tank material. In any case, the reinforcement pipe sections lying inside the longitudinal spars are made of less noble, but high-strength material.
In der Ausgestaltung der Erfindung nach Anspruch 8 ergibt sich der Vorteil, daß bei den heute verfügbaren Walzbreiten und den üblichen Tankquerschnitten die Mantelschalen in Längsrichtung einstückig sein können und nicht, wie bisher, aus mehreren einzelnen quer verlaufenden Schüssen zusammengesetzt zu werden brauchen. Daraus resultiert eine insgesamt kürzere Schweißnahtlänge und eine leichtere Montage.In the embodiment of the invention according to claim 8, there is the advantage that with the roll widths available today and the usual tank cross sections, the jacket shells can be in one piece in the longitudinal direction and do not, as previously, need to be assembled from several individual transverse wefts. This results in an overall shorter weld seam length and easier assembly.
Die Weiterbidung nach Anspruch 9 hat den Vorteil, daß für eine etwaige Kühlung oder Heizung außer den externen Zuleitungen und Anschlüssen keine weiteren gewichtserhöhenden Maßnahmen am Tank erforderlich sind.The further training according to claim 9 has the advantage that no additional weight-increasing measures on the tank are required for any cooling or heating apart from the external feed lines and connections.

Nach Figur 1 und 2 ist der Tank aus vier parallelen teilkreiszylindrischen Mantelschalen 10 und zwei stirnseitigen Tankböden 11 zusammengesetzt. Wie die Stirnansicht der Figur 2 zeigt, hat der Tank im Querschnitt eine kleeblattartige Form, wobei die Achsen der vier Mantelschalen 10 die Ecken eines Rechtecks definieren. Über untere Sattelstücke 12 und obere Stützelemente 13 ist der Tank mit zwei Container-Stirnrahmen 14 verbunden.According to FIGS. 1 and 2, the tank is composed of four parallel, partially circular
In den Sickenbereichen zwischen jeweils zwei benachbarten Mantelschalen 10 verläuft in Tank-Längsrichtung jeweils ein rohrförmiger Längsholm 15, der, wie besonders deutlich aus Figur 1 oben hervorgeht, an seinen Enden unter etwa 45° oder flacher derart abgeschrägt ist, daß seine kleinste Länge dem Tankinnern zugewandt ist und seine größte Länge an der Stelle endet, wo der betreffende Tankboden 11 ansetzt. An jeden Tankboden 11 sind vier zwickelförmige Blechstücke 16 unter dem genannten Winkel von etwa 45° oder flacher angekantet, die in den jeweiligen Sickenbereich zwischen zwei Mantelschalen 10 eingreifen und gleichzeitig den außerhalb der Mantelschalen 10 gelegenen Teil der schrägen Endfläche des rohrförmigen Längsholms 15 verschließen.In the bead areas between each two
Der Tankmantel ist ferner von zwei Verstärkungsringen 17 umgeben, die der in Figur 2 gezeigten, etwa kleeblattartigen Kontur des Tanks folgen. Senkrecht zur Tankachse sind ferner das Tankinnere durchsetzende rohrförmige Zuganker 18, 19 vorgesehen. Jeweils ein senkrechter Zuganker 18 und ein waagerechter Zuganker 19 sind unmittelbar nebeneinander vorgesehen, so daß sie im Kreuzungsbereich einander berühren und zur weiteren Versteifung miteinander verbunden sein können. Bei einer Tanklänge von 20 Fuß (6058 mm) sind insgesamt vier Zuganker 18, 19 vorgesehen.The tank jacket is also surrounded by two
Jeder Zuganker 18, 19 durchsetzt an seinen Enden den jeweiligen Längsholm 15 vollständig und ragt ein kurzes Stück an dessen Außenseite heraus. Im Durchdringungsbereich ist der Längsholm 15 durch einen eingefügten Rohrabschnitt 20 verstärkt. Wie Figur 1 zeigt, sind die Rohrabschnitte 20 an ihren beiden Enden derart schräg geschnitten, daß die größte Länge jedes Rohrabschnitts 20 dem Tankinnern zugewandt ist. Dadurch wird ein allmählicher Spannungsübergang vom verstärkten Bereich des Längsholms 15 zum nicht-verstärkten Bereich erzielt, wobei die innenliegenden längsten zungenartigen Endbereiche der Rohrabschnitte 20 eine gewisse Elastizität aufweisen.Each
Wie aus der Schnittdarstellung der Figur 3 ersichtlich, ist das Ende des Zugankers 18 sowohl mit dem Längsholm 15 und mit dem Rohrabschnitt 20 sowohl an der im Tankinnern gelegenen als auch an der außerhalb des Tanks befindlichen Durchdringungsstelle verschweißt. Da die verstärkende Wirkung des Rohrabschnitts 20 nur dann voll erreicht wird, wenn zwischen diesem und dem rohrförmigen Längsholm 15 Relativbewegungen ausgeschlossen sind, sind diese beiden Bauelemente unmittelbar miteinander über Schweißungen verbunden, die längs der Kanten von im Rohrholm 15 vorgesehenen Aussparungen 21 ausgeführt sind. Die beiden Mantelschalen 10 sind jeweils am Rohrholm 15 angeschweißt.As can be seen from the sectional view in FIG. 3, the end of the
Während die Mantelschalen 10, die Zuganker 18, 19 und die Längsholme 15 aus Tankwerkstoff, d.h. bei entsprechender Verwendungsbestimmung des Tanks aus Edelstahl, bestehen, sind die mit dem Ladegut nicht in Berührung kommenden Rohrabschnitte 20 aus hochfestem Bau- oder Feinkornstahl gefertigt.While the
Eine weiter Einsparung an hochwertigem Tankwerkstoff ist dadurch zu erreichen, daß auch der durchgehende Längsholm 15 aus weniger hochwertigem Tankwerkstoff gefertigt wird und gemäß Figur 4 in seinem im Tankinnern liegenden Bereich von einer teilzylindrischen Hülse 22 aus Tankwerkstoff umgeben ist, die an ihren Längskanten mit dem Längsholm 15 verschweißt ist und an der die Mantelschalen 10 ansetzen.A further saving in high-quality tank material can be achieved in that the continuous
Geht man von für Binnen-Tankcontainer typischen Abmessungen aus, die eine Höhe vom 2600 mm und eine Breite von ca. 2500 mm aufweisen, so haben in der kleeblattartigen Konfiguration nach Figur 2 bei einer Verwendung von rohrförmigen Längsholmen 15 mit einem Durchmesser von etwa 200 mm die Mantelschalen eine Bogenlänge von etwas weniger als 2000 mm. Diese Breite läßt sich im modernen Kaltwalzverfahren herstellen. Der Einsatz der gezeigten rohrförmigen Längsholme 15 gestattet es daher, die Mantelschalen 10 quer zur Walzrichtung zu wölben, so daß iml Gegensatz zu herkömmlichen, aus mehreren quer verlaufenden Blechschüssen zusammengesetzten Tankmänteln im vorliegenden Fall einstückige Mantelschalen 10 eingesetzt werden können, die über die gesamte Tanklänge durchlaufen.If one starts from dimensions typical for inland tank containers, which have a height of 2600 mm and a width of approximately 2500 mm, then in the cloverleaf-like configuration according to FIG. 2 when using tubular
Die rohrförmigen Längsholme 15 und Zuganker 18, 19 können zur Leitung eines Kühl- oder Heizmediums herangezogen werden, das über (nicht dargestellte) externe Zuleitungen und Anschlüsse zugeführt wird. In diesem Fall ist es zweckmäßig, die Zuganker 18, 19 an denjenigen Stellen, an denen sie die Längsholme 15 durchdringen, mit Öffnungen 23 (Figur 3) zu versehen, um ein zusammenhängendes Rohrsystem zu bilden.The tubular
