Description

Großvolumiσer Behälter zur Aufnahme von flüssigen Medien Large volume container for holding liquid media

Die Erfindung bezieht sich auf einen großvolumigen Behälter zur Aufnahme von flüssigen Medien, bestehend aus zwei schalenartigen Endteilen mit jeweils einer ringförmigen, ebenen Anschlußfläche und aus mindestens einem hülsenartigen, aus mindestens zwei Ringsegmenten zusammengesetzten, zwei ebenfalls ringförmige und ebene Anschlußflächen sowie eine Füll- und Entleerungsöffnung aufweisenden Mittelteil, wobei sowohl die beiden Endteile als auch die Ringsegmente des Mittelteiles mit einer Innenschicht und einer Außenschicht im Blasverf hren hergestellt, mit äußeren, als Kammern ausgebildeten Versteifungsrippen versehen und im Bereich ihrer Anschlußflächen durch eine innere und eine äußere Schweißung miteinander verbunden sind.The invention relates to a large-volume container for holding liquid media, consisting of two shell-like end parts, each with an annular, flat connecting surface and at least one sleeve-like, composed of at least two ring segments, two likewise annular and flat connecting surfaces and a filling and emptying opening having central part, both the two end parts and the ring segments of the central part having an inner layer and an outer layer being blown, provided with outer stiffening ribs designed as chambers and connected to one another in the region of their connecting surfaces by an inner and an outer weld.

Es ist eine Vorrichtung zur Lagerung und zum Transport von flüssigen Medien bekannt geworden, die aus einem großvolumigen Behälter besteht, der aus mindestens zwei Teilen durch Schweißung zusammengesetzt ist. Dabei ist jedes Teil im Blasverfahren hergestellt und weist eine Innenwand und eine allseitig damit verbundene Außenwand auf, wobei die Innenwand weitgehend glatt ausgebildet ist und die Außenwand durch Kammern zwischen der Innenwand und der Außenwand geformte Versteifungsrippen besitzt. Die miteinander zu verbindenden Teile besitzen ringförmige und ebene Anschlußflächen, über die die Teile durch eine innere und eine äußere Schweißnaht miteinander verbunden sind. Aufgrund der Ausgestaltung der Teile im Bereich der Anschlußflächen ist die Schweißverbindung äußerst problematisch auszuführen und die an- gestrebte Verbindung wird nicht immer in zufriedenstellender Weise erreicht.A device for storing and transporting liquid media has become known, which consists of a large-volume container, which is composed of at least two parts by welding. Each part is manufactured in the blow molding process and has an inner wall and an outer wall connected to it on all sides, the inner wall being largely smooth and the outer wall having stiffening ribs formed by chambers between the inner wall and the outer wall. The parts to be connected to one another have ring-shaped and flat connecting surfaces, via which the parts are connected to one another by an inner and an outer weld seam. Due to the design of the parts in the area of the connection surfaces, the welded connection is extremely problematic and the desired connection is not always achieved in a satisfactory manner.

Der Erfindung liegt deshalb die Aufgabe zugrunde, einen derartigen bekannten, großvolumigen Behälter so auszugestalten, daß eine optimale Schweißverbindung erreicht werden kann und der Behälter, auch bei besonders großen Volumen, insbesondere im Verbindungsbereich, eine ausreichende Festigkeit und Stabilität aufweist.The invention is therefore based on the object of designing such a known, large-volume container in such a way that an optimal welded connection can be achieved and the container, even with particularly large volumes, in particular in the connection area, has sufficient strength and stability.

Zur Lösung dieser Aufgabe wird gemäß der Erfindung bei einem Behälter der eingangs beschriebenen Gattung vorgeschlagen, daß sowohl die beiden Endteile als auch die Ringsegmente im Bereich ihrer Anschlußflächen eine umlaufende Kammer besitzen und die Anschlußflächen an ihren umlaufenden Begrenzungskanten in zurücklaufende Schrägen zur Bildung von Schweißnuten zwischen den Endteilen und/oder Ringsegmenten übergehen.To achieve this object, it is proposed according to the invention in a container of the type described in the introduction that both the two end parts and the ring segments have a circumferential chamber in the region of their connecting surfaces and the connecting surfaces at their circumferential boundary edges in returning bevels to form welding grooves between the Overlap end parts and / or ring segments.

Durch diese Ausgestaltung der Endteile und der Ringsegmente wird eine besonders gute Verbindung zwischen diesen Teilen erreicht, so daß der Behälter, insbesondere auch bei Volumen über 1000 1, eine sehr gute Festigkeit und Stabilität besitzt. Darüber hinaus besitzt ein solcher Behälter aber auch im Bereich seiner Schweißnähte ein besonders gutes Aussehen.This configuration of the end parts and the ring segments results in a particularly good connection between these parts, so that the container, particularly in the case of volumes over 1000 l, has very good strength and stability. In addition, such a container also has a particularly good appearance in the area of its weld seams.

Weitere Merkmale eines Behälters gemäß der Erfindung sind in den Ansprüchen 2 bis 7 offenbart.Further features of a container according to the invention are disclosed in claims 2 to 7.

Die Erfindung wird nachfolgend anhand eines in einer Zeichnung dargestellten Ausführungsbeispiele näher erläutert. Dabei zeigenThe invention is explained in more detail below with reference to an exemplary embodiment shown in a drawing. Show

Erfindung,Invention,

Fig. 3 einen Schnitt eines Verbindungsbereiches zwischen einem Endteil und einem aus mindestens zwei Ringsegmenten zusammengesetzten Mittelteil.3 shows a section of a connection area between an end part and a middle part composed of at least two ring segments.

In den Figuren 1 und 2 der Zeichnung ist ein großvolumiger Behälter 1 gezeigt, der zur Lagerung von flüssigen Medien, beispielsweise zur Aufnahme von Regenwasser, dient. Dieser Behälter 1, der ein Fassungsvolumen von etwa 3,0 bis 4,0 m3 aufweisen kann, ist aus Kunststoff gefertigt und im dargestellten Ausführungsbeispiel aus einem hohlen Mittelteil 2 mit etwa kreisförmigen Querschnitt gebildet, das an seinen beiden Stirnseiten 3 durch jeweils ein mulden- bzw. schalenartiges Endteil 4 zu dem geschlossenen Behälter 1 zusammengesetzt ist. Auch das Mittelteil 2 selbst ist im dargestellten Ausführungsbeispiel aus drei Ringsegmenten 2a, 2b, 2c zusammengesetzt. Sowohl die Ringsegmente 2a, 2b, 2c als auch die beiden Endteile 4 sind durch Schweißung fest und dichtend miteinander verbunden.In Figures 1 and 2 of the drawing, a large-volume container 1 is shown, which is used to store liquid media, for example for receiving rainwater. This container 1, which can have a capacity of approximately 3.0 to 4.0 m 3 , is made of plastic and, in the exemplary embodiment shown, is formed from a hollow central part 2 with an approximately circular cross-section, which has a trough on its two end faces 3 - or shell-like end part 4 is assembled to the closed container 1. The middle part 2 itself is also composed of three ring segments 2a, 2b, 2c in the exemplary embodiment shown. Both the ring segments 2a, 2b, 2c and the two end parts 4 are firmly and sealingly connected to one another by welding.

Die Figuren 1 und 2 zeigen weiter, daß alle drei Ringsegmente 2a, 2b, 2c und die beiden Endteile 4 Versteifungsrippen 5 aufweisen, die etwa den gleichen Querschnitt besitzen, aber unterschiedlich lang geformt sein können. Ferner ist diesen Figuren zu entnehmen, daß an dem oberen Ringsegment 2c des Mittelteiles 2 ein Dom 6 geformt ist. Im unteren Bereich der Ringsegmente 2a und 2b können Füße vorgesehen sein, die entweder einstückig mit den Ringsegmenten 2a, 2b geformt oder getrennt angebracht sind. Bedarfsweise können diese Füße entfallen oder an einem Endteil 4 angeordnet bzw. ausgebildet sein.Figures 1 and 2 further show that all three ring segments 2a, 2b, 2c and the two end parts 4 have stiffening ribs 5, which have approximately the same cross section, but can be shaped differently long. It can also be seen from these figures that a dome 6 is formed on the upper ring segment 2c of the central part 2. In the lower area of the ring segments 2a and 2b, feet can be provided, which are either integral with the ring segments 2a, 2b are shaped or attached separately. If necessary, these feet can be omitted or can be arranged or formed on an end part 4.

Die Innenseite des Behälters 1 und damit die Innenseiten der Ringsegmente 2a, 2b, 2c und der Endteile 4 weisen eine vollkommen glatte, jedoch der Kontur des Behälters 1 angepaßte Oberfläche auf, während sich die Versteifungsrippen 5 nur an der bzw. den äußeren Wandfläche (n) befinden. Diese äußeren Versteifungsrippen 5 verleihen dem Behälter 1 eine hohe Stabilität - auch bei verhältnismäßig großem Volumen - während durch die glatte, innere Oberfläche sichergestellt ist, daß sich kein Schmutz in Vertiefungen absetzen kann. Damit ist auch eine leichte Reinigung des Behälters 1 sichergestellt.The inside of the container 1 and thus the inside of the ring segments 2a, 2b, 2c and the end parts 4 have a completely smooth surface, but adapted to the contour of the container 1, while the stiffening ribs 5 only on the or the outer wall surface (n ) are located. These outer stiffening ribs 5 give the container 1 a high degree of stability - even with a relatively large volume - while the smooth, inner surface ensures that no dirt can settle in depressions. This also ensures easy cleaning of the container 1.

Die Versteifungsrippen 5 sind, wie die Figur 3 erkennen läßt, durch Kammern 7 gebildet, die bei der Herstellung der Endteile 4 und der Ringsegmente 2a, 2b, 2c durch ein sogenanntes Blasverfahren geformt werden. Dabei wird in an sich bekannter Weise ein schlauchartiger Vorformling aus einem geschmolzenen, thermoplastischen Kunststoff hergestellt und in eine Blasform bewegt, die beispielsweise aus zwei Formhälften besteht und einen der Außenform der Ringsegmente 2a, 2b, 2c bzw. der Endteile 4 entsprechenden Formhohlraum besitzt. Nach dem Schließen der Blasform wir der darin befindliche Vorformling mit Blasluft beaufschlagt, wodurch der Vorformling an der Innenwand des Formhohlratimes der Blasform zum Anliegen gebracht wird. Die Ringsegmente 2a, 2b, 2c und die Endteile 4 besitzen nun eine Innenwand 10 und eine Außenwand 11, die teilweise dicht aneinanderliegen und lediglich im Bereich der Versteifungsrippen 5 durch die Kammern 7 vonein- ander getrennt sind. In den Bereichen, in denen die Innenwand 10 und die Außenwand 11 aneinanderliegen, findet eine Art Verschweißen dieser Schichten statt, wodurch sich eine besonders stabile Wandung ergibt. Dabei läßt die Figur 3 auch erkennen, daß die Kammer 7 und damit die Versteifungsrippen 5 ausschließlich durch die Außenwandung 11 geformt sind und die Innenwandung 10 keinerlei bzw. keiner nennenswerten Verformung unterliegt.The stiffening ribs 5, as can be seen in FIG. 3, are formed by chambers 7, which are formed in the manufacture of the end parts 4 and the ring segments 2a, 2b, 2c by a so-called blowing process. In this case, a tube-like preform is produced from a molten, thermoplastic material in a manner known per se and is moved into a blow mold which, for example, consists of two mold halves and has a mold cavity corresponding to the outer shape of the ring segments 2a, 2b, 2c or the end parts 4. After the blow mold has been closed, blowing air is applied to the preform located therein, as a result of which the preform is brought into contact with the inner wall of the hollow mold of the blow mold. The ring segments 2a, 2b, 2c and the end parts 4 now have an inner wall 10 and an outer wall 11, some of which lie close together and only in the area of the stiffening ribs 5 through the chambers 7. are separated. In the areas in which the inner wall 10 and the outer wall 11 abut one another, these layers are welded together, which results in a particularly stable wall. 3 also shows that the chamber 7 and thus the stiffening ribs 5 are formed exclusively by the outer wall 11 and the inner wall 10 is not subject to any or no significant deformation.

Die in der Figur 3 dargestellten Kammern 5 gehören zu einem Endteil 4 und zu einem Ringsegment 2a des Mittelteiles 2, wobei durch diese Kammern 7 Anschlußflächen 12 geformt sind, über die das Endteil 4 und das Ringsegment 2a einander berühren. Gemäß der Erfindung sind die Kammern 7 umlaufend ausgebildet und befinden sich somit auch in den Bereichen, in denen die Ringsegmente 2a, 2b, 2c des Mittelteiles 2 miteinander verbunden sind. Diese möglichst ebenen Anschlußflächen 12, die bei den Endteilen 4 und dem zusammengesetzten Mittelteil 2 ringförmig verlaufen, gehen an ihren umlaufenden Begrenzungskanten in Schrägen 13 über, so daß zwischen dem Endteil 4 und dem Mittelteil 2 an zwei sich gegenüberliegenden Seiten jeweils eine V-förmige Schweißnut 14 entsteht. Diese Schrägen 13 verlaufen unter einem Winkel von etwa 15 bis 45 Grad.The chambers 5 shown in FIG. 3 belong to an end part 4 and to a ring segment 2a of the middle part 2, whereby through these chambers 7 connection surfaces 12 are formed, via which the end part 4 and the ring segment 2a touch each other. According to the invention, the chambers 7 are circumferential and are therefore also located in the areas in which the ring segments 2a, 2b, 2c of the central part 2 are connected to one another. This as flat as possible connecting surfaces 12, which run annularly in the end parts 4 and the composite middle part 2, pass at their circumferential boundary edges in bevels 13, so that between the end part 4 and the middle part 2 on two opposite sides in each case a V-shaped welding groove 14 arises. These slopes 13 run at an angle of about 15 to 45 degrees.

Die Figur 3 läßt auch erkennen, daß die innere Wandung 10 dicker als die äußere Wandung 11 ausgebildet ist. Dies kann durch eine entsprechende Steuerung des Extrusionsvorganges erreicht werden. Die sogenannte Blasöffnung 15 befindet sich immer in der Außenwand 11. Dies bringt den Vorteil mit sich, daß die Blasöffnung 15, beispielsweise nach dem Entfernen eines Blasansatzes, nicht mehr geschlossen werden muß. Über diese Blasöffnung 15 kann ein fließfähiger Werkstoff, beispielsweise Beton, in die Kammern 7 der Ringsegmente 2a, 2b, 2c und der Endteile 4 eingefüllt bzw. eingegossen werden, wodurch sich die Standfestigkeit des Behälters 1 verbessert. Die Innenschicht 10 der Ringsegmente 2a, 2b, 2c und der Endteile 4 kann in vorteilhafter Weise aus einem schaumfähigen, insbesondere offenporigen Kunststoff bestehen. FIG. 3 also shows that the inner wall 10 is thicker than the outer wall 11. This can be achieved by controlling the extrusion process accordingly. The so-called blowing opening 15 is always located in the outer wall 11. This has the advantage that the blowing opening 15 no longer has to be closed, for example after a blowing attachment has been removed. About this blow opening 15 can flowable material, for example concrete, are poured or poured into the chambers 7 of the ring segments 2a, 2b, 2c and the end parts 4, which improves the stability of the container 1. The inner layer 10 of the ring segments 2a, 2b, 2c and the end parts 4 can advantageously consist of a foamable, in particular open-pore plastic.
