Container with a lining consisting of glass-fibre reinforced laminated plastic (2) GFK-Laminate) and an intermediate layer (4) made from closed-cell foam material arranged between the lining (2) and the container inner wall (3) and glued to the latter, characterised by the fact that the lining (2) is only at the top container rim directly joined to the latter, that the lining (2) is directly joined to at least one attachment intermediate layer (5, 5a, 5', 5") fixed to the container inner wall (3) and that the lining (2) in the other zones hangs loosely and in a selfsupporting manner in the container (1).

Description

Die Erfindung betrifft einen Behälter mit einer Auskleidung, insbesondere einer aus einem GFK-Laminat bestehenden Auskleidung, und mit einer zwischen der Auskleidung und der Behälterinnenwand angeordneten Zwischenschicht, wobei die Auskleidung mindestens am oberen Behälterrand am Behälter befestigt ist.The invention relates to a container with a lining, in particular a lining consisting of a GRP laminate, and with an intermediate layer arranged between the lining and the inner wall of the container, the lining being attached to the container at least at the upper edge of the container.

Derartige Behälterauskleidungen werden im allgemeinen aus einem chemisch widerstandsfähigen Material hergestellt, beispielsweise aus glasfaserverstärktem Kunststofflaminat (GFK-Laminat), um einen aus Beton oder Stahl bestehenden Behälter zur Aufnahme von chemisch aggresiven Stoffen geeignet zu machen.Container liners of this type are generally made from a chemically resistant material, for example from glass fiber reinforced plastic laminate (GRP laminate), in order to make a container made of concrete or steel suitable for holding chemically aggressive substances.

Bei Stahlbehältern wird hierzu üblicherweise auf die metallisch blanke Stahloberfläche, die durch Sandstrahlen vorbereitet wurde, eine Grundierung aufgetragen. Bei Betonbehältern muß die Betonoberfläche trocken, öl- und staubfrei sein und eine ausreichende Zugfestigkeit aufweisen. Auf die so vorbereitete Oberfläche wird eine Füllstoffmischung aus Kunststoff aufgetragen, auf der dann das GFK-Laminat flächig haftend aufgebracht wird. Die oberste Schicht des GFK-Laminats kann als Versiegelung mit besonders dichter und chemisch widerstandsfähiger Oberfläche ausgeführt sein.In the case of steel containers, a primer is usually applied to the bare metal surface prepared by sandblasting. For concrete containers, the concrete surface must be dry, free of oil and dust and have sufficient tensile strength. On the surface prepared in this way a filler mixture made of plastic is applied, on which the GRP laminate is then adhered. The top layer of the GRP laminate can be designed as a seal with a particularly dense and chemically resistant surface.

Bei rauhem Untergrund, wie er beispielsweise auch bei neuen Betonbehältern vorliegt, muß die Füllstoffschicht mindestens so dick sein, daß sie alle herausragenden Unebenheiten des Untergrunds ausgleicht. Wegen der festen Verbindung der Auskleidung mit der Füllstoffzwischenschicht und mit der Behälterinnenwand dürfen keine Setzrisse oder andere nachträgliche Bewegungen in der Behälterwand zugelassen werden, da sich diese auf die Auskleidung übertragen würden und dort ebenfalls zur Rißbildung führen könnten.In the case of rough subsoil, as is also the case, for example, with new concrete containers, the filler layer must be at least so thick that it compensates for all outstanding unevenness in the subsoil. Because of the firm connection of the lining with the filler intermediate layer and with the inner wall of the container, no set cracks or other subsequent movements in the wall of the container may be permitted, as these would be transferred to the lining and could also lead to cracking there.

Besondere Schwierigkeiten bereitet die Anbringung einer Auskleidung an alten Behältern, deren Behälterinnenwand bei Betonbehältern oftmals nicht mehr die erforderliche Zugfestigkeit aufweist oder sogar Risse hat. Bei Stahlbehältern kann beispielsweise eine alte Gummierungsschicht vorhanden sein, deren Abtragung mit erheblichem Arbeitsaufwand verbunden wäre. Da bei Betonbehältern oder mit einer Ausmauerung versehenen Behältern an der Behälterinnenwand soviel Material abgetragen werden müßte, bis ein ausreichend fester und rißfreier Untergrund vorliegt, ist hierfür nicht nur ein erheblicher Arbeitsaufwand erforderlich; es entsteht in den meisten Fällen auch eine Oberfläche mit großen Unebenheiten, für deren Ausgleich sehr viel Material benötigt wird.It is particularly difficult to attach a lining to old containers, the inner wall of which in concrete containers often no longer has the required tensile strength or even has cracks. In the case of steel containers, for example, an old rubber coating can be present, the removal of which would require considerable work. Since in concrete containers or containers provided with a lining, so much material would have to be removed from the inner wall of the container until a sufficiently firm and crack-free base is present, this not only requires a considerable amount of work; in most cases, a surface with large unevenness is created, for the compensation of which a lot of material is required.

Aufgabe der Erfindung ist es daher, einen Behälter mit einer Auskleidung der eingangs genannten Art so auszuführen, daß die erforderlichen Vorarbeiten wesentlich verringert werden, so daß auch alte Behälter, deren Innenwand an sich nicht zur Verbindung mit einer Auskleidung geeignet ist, ohne übermäßigen Arbeitsaufwand nachträglich mit einer Auskleidung versehen werden können, ohne daß Risse und lose Teile der Behälterinnenwand die Auskleidung beeinträchtigen.The object of the invention is therefore to carry out a container with a lining of the type mentioned in such a way that the necessary preparatory work is substantially reduced, so that even old containers, the inner wall of which is not suitable for connection to a lining, can be retrofitted without excessive work can be provided with a lining without cracks and loose parts of the inner wall of the container impairing the lining.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Zwischenschicht aus weichelastischem Material besteht. Dadurch wird die Übertragung von Kräften zwischen der Behälterinnenwand und der Auskleidung weitestgehend unterbunden. Deshalb können weder von der Auskleidung auf die Behälterinnenwand ausgeübte Zugbeanspruchungen zu Ablösungen an der Behälterinnenwand führen, noch können Risse und andere Beschädigungen einen schädigenden Einfluß auf die Auskleidung haben, sogar wenn die Risse noch nachträglich Bewegungen ausführen sollten. Unebenheiten der Behälterinnenwand durchdringen die weichelastische Zwischenschicht nicht und können deshalb nicht zu Beschädigungen der Auskleidung führen. Lose oder in anderer Weise für die Verbindung mit einer Auskleidung nicht geeignete Teile der Behälterinnenwand, beispielsweise Reste von alten Auskleidungen, brauchen nicht entfernt zu werden, wodurch sich die Anforderungen an die Vorbereitung der Behälterinnenwand wesentlich verringern.This object is achieved in that the intermediate layer consists of soft elastic material. This largely prevents the transfer of forces between the inner wall of the container and the lining. Therefore, tensile stresses exerted by the lining on the inner wall of the container cannot lead to detachments on the inner wall of the container, nor can cracks and other damage have a damaging effect on the lining, even if the cracks should still make subsequent movements. Unevenness in the inner wall of the container does not penetrate the soft, elastic intermediate layer and therefore cannot damage the lining. Loose or otherwise unsuitable parts of the inner wall of the container, for example remnants of old linings, do not have to be removed, which considerably reduces the requirements for the preparation of the inner wall of the container.

Vorzugsweise besteht die Zwischenschicht aus feinporigem, geschlossenporigem Schaummaterial, wobei sich Polyäthylenschaum besonders bewährt hat, der vorzugsweise aus lose eingebrachten Flächenstücken, wie Platten oder Bahnen, besteht.The intermediate layer preferably consists of fine-pore, closed-pore foam material, whereby Polyethylene foam has proven particularly effective, which preferably consists of loosely inserted sheets, such as sheets or sheets.

Da im Bereich des eingebrachten Schaummaterials keine tragende Verbindung zwischen der Auskleidung und der Behälterinnenwand besteht, wird die Auskleidung durch ihre eigene Zugfestigkeit wie ein in den Behälter eingehängtes Hemd getragen, wobei der obere Rand der Auskleidung am Behälter befestigt ist..Since there is no load-bearing connection between the lining and the inner wall of the container in the area of the introduced foam material, the lining is worn by its own tensile strength like a shirt suspended in the container, the upper edge of the lining being fastened to the container.

Für höhere Behälter, bei denen diese herkömmliche Befestigung der Auskleidung am oberen Behälterrand nicht ausreicht, wird in besonders vorteilhafter Ausgestaltung des Erfindungsgedankens vorgesehen, daß die Auskleidung in im Abstand zueinander angeordneten Befestigungsflächenbereichen fest mit der Gehälterinnenwand verbunden ist und daß die weichelastische Zwischenschicht nur außerhalb dieser Befestigungsflächenbereiche zwischen der Auskleidung und der Behälterinnenwand angeordnet ist.For higher containers, in which this conventional fastening of the lining at the upper edge of the container is not sufficient, it is provided in a particularly advantageous embodiment of the inventive concept that the lining is firmly connected to the inner wall of the saline in spaced-apart fastening surface regions and that the soft-elastic intermediate layer is only outside these fastening surface regions is arranged between the lining and the inner wall of the container.

Vorzugsweise sind in den Befestigungsflächenbereichen Befestigungszwischenlagen an der Behälterinnenwand befestigt und die Auskleidung ist hieran fest angebracht. Die Befestigungszwischenlagen können beispielsweise senkrechte Streben und/oder - bei im wesentlichen rotationssymmetrischen Behältern - Ringe oder Ringsegmente sein, die an der Behälterinnenwand angedübelt oder in sonstiger Weise befestigt sein können. Die Befestigungszwischenlagen können aus Stahl oder GFK bestehen. An ihrer Innenseite ist die aus GFK-Laminat bestehende Auskleidung durch Adhäsion angebracht.Fastening intermediate layers are preferably fastened to the inner wall of the container in the fastening surface regions and the lining is firmly attached thereto. The intermediate fastening layers can be, for example, vertical struts and / or — in the case of essentially rotationally symmetrical containers — rings or ring segments which can be dowelled on the inner wall of the container or fastened in some other way. The fastening intermediate layers can consist of steel or GRP. The lining made of GRP laminate is attached to its inside by adhesion.

Die Erfindung wird nachfolgend an Ausführungsbeispielen näher erläutert, die in der Zeichnung dargestellt sind. Es zeigt:

  • Fig. 1 einen Behälter mit einer Auskleidung in einem senkrechten Teilschnitt,
  • Fig. 2 eine demgegenüber abgewandelte Ausführungsform der Befestigung der Auskleidung am oberen Behälterrand in einem senkrechten Teilschnitt,
  • Fig. 3 ebenfalls in einem senkrechten Teilschnitt eine weitere Ausführungsform der Befestigung der Auskleidung am Behälter und
  • Fig. 4 in einem Teilschnitt eine andere Ausführungsform der Behälterauskleidung.
The invention is explained in more detail below using exemplary embodiments which are illustrated in the drawing. It shows:
  • 1 is a container with a lining in a vertical partial section,
  • 2 shows a modified embodiment of the fastening of the lining on the upper edge of the container in a vertical partial section,
  • Fig. 3 also in a vertical partial section a further embodiment of the attachment of the lining to the container and
  • Fig. 4 in a partial section another embodiment of the container lining.

Bei den dargestellten Ausführungsbeispielen besteht ein stehender zylindrischer Behälter 1 aus Beton. Der Behälterinnenraum ist mit einer Auskleidung 2 aus einem GFK-Laminat versehen, das beispielsweise ein Rovinglaminat, ein Mattenlaminat oder ein Faserspritzlaminat ist, dessen Glasfasereinlagen der Auskleidung eine ausreichende Zugfestigkeit geben, so daß diese zumindest in gewissem Maße selbsttragend ist. Am oberen Rand des Behälters 1 ist die Auskleidung 2 nach entsprechender Vorbereitung der Behälteroberfläche fest mit diesem verbunden. In den übrigen Bereichen sind zwischen der Auskleidung 2 und der Behälterinnenwand 3 Polyäthylen-Schaumstoffplatten 4 eingelegt, die mit der Behälterinnenwand 3 punktweise durch Klebung verbunden sind, um die eingebrachten Schaumstoffplatten 4 während der Montage zu halten.In the illustrated embodiments, a standing cylindrical container 1 is made of concrete. The interior of the container is provided with a lining 2 made of a GRP laminate, which is, for example, a roving laminate, a mat laminate or a fiber spray laminate, the glass fiber inserts of which give the lining sufficient tensile strength so that it is at least to a certain extent self-supporting. At the upper edge of the container 1, the lining 2 is firmly connected to the container surface after appropriate preparation. In the remaining areas between the lining 2 and the container inner wall 3 polyethylene foam sheets 4 are inserted, which are connected point by point to the container inner wall 3 to hold the inserted foam sheets 4 during assembly.

In senkrechten Abständen zueinander und zum oberen Behälterrand sind aus Stahl bestehende Ringe 5, die auch aus einzelnen Ringsegmenten 5' bestehen können, mittels Dübeln 6 und Dübelschrauben 7 an der Wand des Behälters 1 befestigt. An der Oberfläche der Ringe 5 oder Ringsegmente 5' ist die Auskleidung 2 durch Adhäsion angebracht. In den dazwischenliegenden Bereichen liegt die Auskleidung 2 nur lose an den Schaumstoffplatten 4 an und trägt sich selbst. Der Abstand zwischen den Ringen 5 bzw. Ringsegmenten 5' ist so gewählt, daß ein Ausbeulen der Auskleidung 2 verhindert wird.At vertical intervals to each other and to the upper Be the edge of the container are made of steel rings 5, which can also consist of individual ring segments 5 ', fastened to the wall of the container 1 by means of dowels 6 and dowel screws 7. The lining 2 is attached to the surface of the rings 5 or ring segments 5 'by adhesion. In the areas in between, the lining 2 lies only loosely on the foam sheets 4 and supports itself. The distance between the rings 5 or ring segments 5 'is selected such that bulging of the lining 2 is prevented.

Anstelle der RingeS oder Ringsegmente 5' oder zusätzlich dazu können jeweils im Abstand zueinander vertikale Streben 5 a vorgesehen werden, die beim dargestellten Ausführungsbeispiel ebenfalls aus Stahl bestehen und in der beschriebenen Weise mit der Behälterinnenwand 3 und der Auskleidung 2 verbunden sind.Instead of the rings S or ring segments 5 'or in addition thereto, vertical struts 5 a can be provided at a distance from one another, which in the illustrated embodiment also consist of steel and are connected to the inner wall 3 of the container and the lining 2 in the manner described.

Am Rand des Behälterbodens kann eine Eckenausrundung 8 durch eine Spachtelschicht 9 vorgesehen werden.At the edge of the container bottom, a corner fillet 8 can be provided by a spatula layer 9.

Zur Aufnahme der Auskleidung 2 wurde die Behälterinnenwand 3 nicht wrbearbeitet; sie kann Unebenheiten, alte undichte Ausmauerungen, mehr oder minder lose Oberflächenbereiche oder Reste einer alten Oberflächenbeschichtung tragen. Der Behälter 1 selbst kann Risse oder Fugen aufweisen. Die Schaumstoffplatten 4 bilden eine Pufferschicht, die eine nachteilige Beeinflussung der Auskleidung 2 durch den Behälter 1 und insbesondere seine Oberflächenbeschaffenheit verhindert.The container inner wall 3 was not machined to accommodate the lining 2; it can carry bumps, old leaking brickwork, more or less loose surface areas or remnants of an old surface coating. The container 1 itself may have cracks or joints. The foam sheets 4 form a buffer layer, which prevents the liner 2 from being adversely affected and, in particular, its surface quality.

Die Streben 5a, Ringe 5 bzw. Ringsegmente 5' bilden hierbei die Befestigungsflächenbereiche, an denen die als Hemd in den Behälter 1 eingehängte Auskleidung 2 getragen wird.The struts 5a, rings 5 or ring segments 5 'form here in the fastening surface areas on which the lining 2, which is suspended as a shirt in the container 1, is worn.

Eine abgewandelte Art der Befestigung der Auskleidung 2 am oberen Rand des Behälters 1 ist in Fig. 2 gezeigt. Dort ist am oberen Behälterrand an der Behälterinnenwand 3 ein Stehlring 5 angedübelt, der mit dem oberen Rand der Auskleidung 2 durch Adhäsion verbunden ist. Diese Befestigungsart bietet sich insbesondere dann an, wenn der Behälter einen (nicht dargestellten) Deckel trägt, der nicht entfernt werden kann, so daß die Oberseite des Behälterrands nicht für die Anbringung der Auskleidung 2 zugänglich ist.A modified way of fastening the liner 2 to the upper edge of the container 1 is shown in FIG. 2. There is a standing ring 5 attached to the upper edge of the container on the inner wall 3 of the container, which ring is connected to the upper edge of the lining 2 by adhesion. This type of attachment is particularly useful when the container has a cover (not shown) that cannot be removed, so that the top of the container edge is not accessible for the attachment of the liner 2.

Die Streben 5a, Ringe 5, Ringsegmente 5' oder ähnliche Befestigungszwischenlagen können beispielsweise auch aus GFK bestehen und am Behälter 1 angeklebt oder ebenfalls angedübelt sein.The struts 5a, rings 5, ring segments 5 'or similar fastening intermediate layers can, for example, also consist of GRP and be glued to the container 1 or also be dowelled.

Eine weitere abgewandelte Ausführungsform ist in Fig. 3 gezeigt. Dort ist die GFK-Auskleidung 2 an senkrecht angeordneten oder ringförmig umlaufenden Streifen 5'' aus Kunstharzbeton angeklebt, die in ausgestemmte Nuten 6 der Wand des Behälters 1 eingebracht sind. Ebenso wie bei den Ausführungsbeispielen nach den Fig. 1 und 2 befinden sich zwischen Streifen 5'' jeweils die Schaumstoffplatten 4, an deren Oberfläche die Auskleidung 2 lose anliegt.A further modified embodiment is shown in FIG. 3. There, the GRP lining 2 is glued to vertically arranged or annular circumferential strips 5 ″ made of synthetic resin concrete, which are introduced into mortised grooves 6 of the wall of the container 1. Just as in the exemplary embodiments according to FIGS. 1 and 2, the foam sheets 4 are located between strips 5 ″, on the surface of which the lining 2 lies loosely.

Eine weitere abgewandelte Ausführungsform ist in Fig. 4 gezeigt. Dort ist die GFK-Auskleidung 2 durch innen angebrachte GFK-Rippen 2a versteift, die beispielsweise zugleich als Wirbelbrecher in Rührwerksbehältern dienen. Die Rippen 2a erhöhen die Festigkeit der Auskleidung 2 so, daß zusätzliche Befestigungszwischenlagen wie die Ringe 5 od. dgl., nicht oder nur in verhältnismäßig großen Abständen vorgesehen werden.Another modified embodiment is shown in FIG. 4. There, the GRP lining 2 is on the inside brought reinforced GRP ribs 2a, which, for example, also serve as vortex breakers in agitator tanks. The ribs 2a increase the strength of the liner 2 so that additional fastening intermediate layers such as the rings 5 or the like are not provided or are only provided at relatively large intervals.

Anstelle der beschriebenen Ausführung des Behälters 1 aus Beton kann der Behälter 1 beispielsweise auch aus Stahl bestehen und an seiner Behälterinnenwand 3 eine Gummiarmierung oder eine sonstige Beschichtung oder Reste davon tragen, die zumindest im Bereich der Schaumstoffplatten 4 nicht entfernt werden müssen, um die Auskleidung 2 anzubringen.Instead of the described design of the container 1 made of concrete, the container 1 can also consist, for example, of steel and have a rubber reinforcement or some other coating or remnants thereof on its inner wall 3, which does not have to be removed at least in the area of the foam sheets 4 in order to cover the lining 2 to attach.

Anstelle des beschriebenen Schaumstoffmaterials für die Platten 4 kann auch ein anderes weichelastisches Material verwendet werden, beispielsweise Flächenstücke aus Thermoplast.Instead of the foam material described for the plates 4, another soft-elastic material can also be used, for example sheets made of thermoplastic.
