Description

Die Erfindung betrifft eine Schale für die Herstellung eines Hybrid-Auflagerings, einen Hybrid-Auflagering und ein Schachtbauwerk mit einem solchen Hybrid-Auflagering.The invention relates to a shell for producing a hybrid support ring, a hybrid support ring and a shaft structure with such a hybrid support ring.

Beim Bau von Abwasserschächten oder Straßenabläufen sind zur Aufnahme von Abdeckungen, beispielsweise in Form eines Gitters oder einer Platte, lastverteilende Auflageringe notwendig.When building sewage shafts or street gullies, load-distributing support rings are necessary to accommodate covers, for example in the form of a grid or plate.

Diese sind aus Gusseisen, Beton, Stahlfaserbeton oder Polymermaterial.These are made of cast iron, concrete, steel fiber concrete or polymer material.

Am meisten verbreitet sind solche lastverteilenden Auflageringe aus Beton. Diese besitzen jedoch ein sehr hohes Eigengewicht und sind beim Transport und beim Einbau bruchanfällig, obwohl diese eine Stahlbewehrung aufweisen.The most common are such load-distributing support rings made of concrete. However, these have a very high weight and are susceptible to breakage during transport and installation, even though they have steel reinforcement.

Ein weiterer Nachteil besteht darin, dass die dem Abwasserschacht zugewandte innere Ringfläche des Auflagerings dem Gasraum des Abwasserbauwerks zugewandt ist. Aufgrund der sich in solchen Abwasserbauwerken sammelnden korrosiven Gase, wie beispielsweise Schwefelwasserstoff und andere, kommt es bei solchen Auflageringen aus Beton an dieser Ringfläche oftmals zu korrosiven Angriffen, sodass der Auflagering innerhalb weniger Jahre erheblich beschädigt oder zerstört wird. Hierdurch senkt sich die Abdeckung gegenüber dem Straßenniveau und muss kostenaufwendig repariert werden.Another disadvantage is that the inner annular surface of the support ring facing the sewage shaft faces the gas space of the sewage structure. Due to the corrosive gases that collect in such wastewater structures, such as hydrogen sulfide and others, corrosive attacks often occur on this ring surface in such concrete support rings, so that the support ring is significantly damaged or destroyed within a few years. This lowers the cover compared to street level and requires costly repairs.

Ein weiterer Nachteil bei solchen Auflageringen aus Beton ist der Angriff durch Tausalze, die gerade im Winter in den Schmelzwässern vorhanden sind und zusammen mit den häufigen Temperaturwechseln ebenso den Beton des Auflagerings angreifen und letztlich zerstören können.Another disadvantage of such concrete support rings is the attack by de-icing salts, which are present in the melt water, especially in winter, and, together with the frequent temperature changes, can also attack and ultimately destroy the concrete of the support ring.

Die JP 2015004199 A offenbart einen Einstellring, der an einem Ende eines Schachtes angebracht ist. Der Schacht umfasst ein Schachtunterteil, einen Einstellring, einen Aufnahmerahmen und einen Gitterdeckel. Das Schachtunterteil weist eine Vielzahl von Schraubenlöchern in der Öffnung auf. In jedes Schraubenloch wird ein Bolzen eingeschraubt. Der Aufnahmerahmen wird lösbar auf eine Oberfläche des Einstellrings aufgesetzt, der Deckelkörper wird von dem Aufnahmerahmen getragen. Dann wird jede Schraube, die in jedem Schraubenloch des Schachtunterteils eingeschraubt ist, durch jedes Einsteckloch des Einstellrings und jedes Einsteckloch des Aufnahmerahmens gesteckt und verschraubt. Damit ist der Aufnahmerahmen mit dem Einstellring und Deckel so durch die Schrauben fixiert, dass er beim Einsetzen in die Öffnung des Schachtunterteils nicht abfällt. Der Einstellring erstreckt sich ringförmig, weist einen rechteckigen Querschnitt mit gleicher Dicke auf. Er umfasst einem Ring aus recyceltem Kunststoff, mit einer ringförmigen Nut, die sich in Umfangsrichtung fortsetzt und nach oben hin öffnet. Die Nut des Ringes ist komplett mit Beton gefüllt. Weiter weist der Einstellring Durchgangs- Löcher auf, durch welche die Schrauben hindurchführbar sind.The JP 2015004199 A discloses an adjustment ring attached to one end of a shaft.

Hier setzt die Erfindung ein, die es sich zur Aufgabe gemacht hat, die vorstehend geschilderten Nachteile des Standes der Technik zu überwinden und dazu einen verbesserten Auflagering bereitzustellen, wozu eine Schale für die Herstellung eines Hybrid-Auflagerings vorgesehen ist.This is where the invention comes in, which has set itself the task of overcoming the disadvantages of the prior art described above and to provide an improved support ring, for which purpose a shell is provided for the production of a hybrid support ring.

Eine weitere Aufgabe der vorliegenden Erfindung liegt darin, einen Hybrid-Auflagering bereitzustellen, der mit Hilfe der Schale hergestellt ist.Another object of the present invention is to provide a hybrid bearing ring made using the shell.

Schließlich ist es noch Aufgabe der vorliegenden Erfindung, ein Schachtbauwerk mit einem solchen Hybrid-Auflagering anzugeben.Finally, it is another object of the present invention to provide a shaft structure with such a hybrid support ring.

Die Lösung der ersten Aufgabe der vorliegenden Erfindung erfolgt durch den Gegenstand des Anspruchs 1.The first object of the present invention is solved by the subject matter of claim 1.

Es wurde im Rahmen der vorliegenden Erfindung erkannt, dass eine Schale für die Herstellung eines Hybrid-Auflagerings die Nachteile des Standes der Technik überwindet, wenn vorgesehen ist, dass die Schale Wände aufweist, durch die ein Volumen definiert ist, das zur Aufnahme eines aushärtenden Materials ausgebildet ist, um den Hybrid-Auflagering durch Aushärten des aushärtenden Materials zu einem ausgehärteten Material zu bilden, wobei die Schale aus einem Polymermaterial, das thermoplastisch oder duroplastisch ist, oder aus einem Metall besteht oder ein solches enthält und diese ringförmig ausgebildet ist und einen Durchgang aufweist, und wobei an der Schale wenigstens eine Auflagefläche des mit der Schale zu bildenden Hybrid-Auflagerings ausgebildet ist, wobei in wenigstens einer Wand wenigstens ein Durchbruch vorgesehen ist, welche sich dadurch auszeichnet, dass die Auflagefläche eine erste Auflagefläche ist, deren Oberfläche strukturiert ist, wobei diese eine Vielzahl von Vertiefungen und Erhöhungen aufweist, dass eine Vielzahl von Durchbrüchen in der Wand der Schale vorgesehen sind, dass die Durchbrüche in der ersten Auflagefläche der Schale angeordnet sind.It was recognized in the context of the present invention that a shell for the production of a hybrid support ring overcomes the disadvantages of the prior art if it is provided that the shell has walls through which a volume is defined which is suitable for receiving a hardening material is designed to form the hybrid support ring by hardening the hardening material into a hardened material, wherein the shell consists of a polymer material that is thermoplastic or thermoset, or of a metal or contains such and is annular and has a passage and wherein at least one support surface of the hybrid support ring to be formed with the shell is formed on the shell, wherein at least one opening is provided in at least one wall, which is characterized in that the support surface is a first support surface, the surface of which is structured, which has a plurality of depressions and elevations, that a plurality of openings are provided in the wall of the shell are that the openings are arranged in the first support surface of the shell.

Die erfindungsgemäße Schale ist dabei derartig gestaltet, dass durch Ausfüllen des Volumens, das durch die Wände der Schale definiert ist, mit einem aushärtenden Material und Aushärten des aushärtenden Materials zu einem ausgehärteten Material ein Hybrid-Auflagering bereitstellbar ist, der die vorstehend bei den bekannten Beton-Auflageringen geschilderten Nachteile überwindet.The shell according to the invention is designed in such a way that by filling the volume defined by the walls of the shell with a hardening material and hardening the hardening material to a hardened material, a hybrid support ring can be provided, which has the above-mentioned concrete -Support rings overcomes the disadvantages described.

In einfacher Weise kann dazu der Hybrid-Auflagering entweder in einer Fertigungsstätte oder direkt an der Baustelle dadurch hergestellt werden, dass ein aushärtendes Material, wie beispielsweise Beton, in das Volumen der Schale eingefüllt wird und dort aushärtet.In a simple manner, the hybrid support ring can be produced either in a production facility or directly at the construction site by filling a hardening material, such as concrete, into the volume of the shell and hardening there.

Je nach Notwendigkeit kann der Beton beispielsweise armiert sein, wozu als solche bekannte Armiereisen bzw. Stahlbauteile Verwendung finden, andere Möglichkeiten der Armierung bestehen darin, dass dem Beton beispielsweise Metallfasern oder Glasfasern oder ähnliches zugefügt werden.Depending on the need, the concrete can, for example, be reinforced, for which reinforcing iron or steel components known as such are used; other options for reinforcement consist of adding metal fibers or glass fibers or the like to the concrete.

Durch die Herstellung des Hybrid-Auflagerings an der Baustelle kann der aufwendige Transport von einer Fertigungsstätte zur Baustelle vermieden werden, hierdurch können die Kosten durch Vermeiden der Lagerhaltung, aber auch die Gefahr von Lager- und Transportschäden vermieden werden.By producing the hybrid support ring at the construction site, the complex transport from a production site to the construction site can be avoided, thereby reducing costs by avoiding storage, but also the risk of storage and transport damage.

Durch das Vorsehen gemäß vorliegender Erfindung, dass an der Schale wenigstens eine Auflagefläche des mit der Schale zu bildenden Hybrid-Auflagerings ausgebildet ist, kann ein solcher Hybrid-Auflagering in besonders einfacher und effizienter Weise hergestellt werden, da so die technischen Notwendigkeiten für diese Auflagefläche hinsichtlich Abmessungen, Gestaltung und Oberflächenausführung gleich durch die Schale vorgebbar sind.By providing according to the present invention that at least one support surface of the hybrid support ring to be formed with the shell is formed on the shell, such a hybrid support ring can be produced in a particularly simple and efficient manner, since this way the technical requirements for this support surface are met Dimensions, design and surface finish can be specified by the shell.

Bei der vorliegenden Erfindung kann sich als sehr günstig erweisen, wenn vorgesehen ist, dass die Schale rotationssymmetrisch zu einer Achse A ausgebildet ist.In the present invention, it can prove to be very advantageous if it is provided that the shell is designed to be rotationally symmetrical to an axis A.

Durch diese Maßnahme kann eine solche Schale sehr einfach hergestellt werden, da ein Werkzeug für eine solche rotationssymmetrisch ausgebildete Schale einfach zu konstruieren und zu bauen ist. Zum anderen ist dadurch mit dieser Schale ein Hybrid-Auflagering in einfacher Weise herstellbar, der ohne besonderen Aufwand in ein Schachtbauwerk einbaubar ist, da dieser aufgrund seiner Rotationssymmetrie in einfacher Weise ausrichtbar ist bzw. keiner besonderen Ausrichtung in Bezug auf die Achse A bedarf.With this measure, such a shell can be produced very easily, since a tool for such a rotationally symmetrical shell is easy to design and build. On the other hand, a hybrid support ring can be produced in a simple manner with this shell, which can be installed in a shaft structure without any special effort, since it can be easily aligned due to its rotational symmetry and does not require any special alignment with respect to the axis A.

Als sehr vorteilhaft kann sich bei der vorliegenden Erfindung ergeben, wenn vorgesehen ist, dass die Wände der Schale an allen Stellen eine gleiche oder eine etwa gleiche Dicke aufweisen.The present invention can be very advantageous if it is provided that the walls of the shell have the same or approximately the same thickness at all points.

Hierdurch kann eine Schale bereitgestellt werden, die ein sehr geringes Gewicht aufweist, und die insbesondere in einem einfachen Herstellverfahren zugänglich ist. Auch ist eine solche Schale überaus maßgenau herzustellen, da so Verzüge oder Einfallstellen vermieden werden können.In this way, a shell can be provided which has a very low weight and which is particularly accessible in a simple manufacturing process. Such a shell must also be manufactured with extreme precision, as this means that distortions or sink marks can be avoided.

Als sehr günstig kann sich bei der vorliegenden Erfindung ergeben, wenn vorgesehen ist, dass die Schale in wenigstens einer Wand wenigstens einen Durchbruch aufweist. Dadurch kann im Bereich des Durchbruchs in der Wand der Schale das ausgehärtete Material, dass das Volumen der Schale beim Hybrid-Auflagering füllt bzw. ausfüllt, in Kontakt treten mit aushärtendem Material, das beim Bau des Schachtbauwerks verwendet wird. Hierdurch kann insbesondere eine verschiebesichere Anordnung des Hybrid-Auflagerings beim Schachtbauwerk erreicht werden, in dem das ausgehärtete Material des Hybrid-Auflagerings beispielsweise mit aushärtenden Material bei der Anordnung der Abdeckung in Kontakt kommt und so eine feste Verbindung mit diesem eingeht, so dass der Hybrid-Auflagering mit der Abdeckung fluiddicht verbunden ist.The present invention can be very advantageous if it is provided that the shell has at least one opening in at least one wall. As a result, in the area of the breakthrough in the wall of the shell, the hardened material that fills or fills the volume of the shell in the hybrid support ring can come into contact with hardening material that is used in the construction of the shaft structure. In this way, a displacement-proof arrangement of the hybrid support ring in the shaft structure can be achieved in particular, in which the hardened material of the hybrid support ring comes into contact, for example, with hardening material when arranging the cover and thus forms a firm connection with it, so that the hybrid Support ring is connected to the cover in a fluid-tight manner.

Es kann mit Vorteil vorgesehen sein, dass nicht nur ein Durchbruch in der Wand der Schale, sondern eine Vielzahl von Durchbrüchen in der Wand der Schale vorgesehen sind. Der oder die Durchbrüche können in verschiedener Weise ausgebildet sein, beispielsweise eine kreisförmige, eine eckige, eine ovale oder eine andersartig gestaltete Geometrie aufweisen, es ist aber auch möglich, dass der oder die Durchbrüche beispielsweise als zur Achse A konzentrischer teilumlaufender Schlitz oder als teilumlaufener spiralfömiger Schlitz ausgebildet ist.It can advantageously be provided that not only one opening in the wall of the shell, but a plurality of openings are provided in the wall of the shell. The opening or openings can be designed in various ways, for example a circular, an angular, an oval or a differently designed geometry, but it is also possible for the opening or openings to be designed, for example, as a partially circumferential slot concentric to the axis A or as a partially circumferential spiral Slot is formed.

Solche Durchbrüche können bereits bei der Urformung der Schale gebildet sein, indem das zur Herstellung eingesetzte Werkzeug solche bereits erzeugt. In anderen Fertigungsprozessen können solche Durchbrüche beispielsweise durch Stanzen oder Fräsen oder andere materialabtragende Techniken hergestellt sein.Such openings can already be formed during the initial shaping of the shell, in that the tool used for production already creates them. In other manufacturing processes, such openings can be made, for example, by punching or milling or other material-removing techniques.

In einer anderen Ausführungsform der Erfindung kann auch vorgesehen sein, dass an der Wand der Schale eine Stelle oder eine Mehrzahl von Stellen, insbesondere gekennzeichnete Stellen vorgesehen sind, an denen die Wandstärke der Schale reduziert ist und beispielsweise nur 5 bis 10 % der Wandstärke beträgt, wie sie in den Bereich vorliegt, die keine derartigen Stellen sind.In another embodiment of the invention it can also be provided that a point or a plurality of points, in particular marked points, are provided on the wall of the shell, at which the wall thickness of the shell is reduced and is, for example, only 5 to 10% of the wall thickness, as it exists in the areas that are not such places.

Wird die Wand beim Hybrid-Auflagering an dieser Stelle beispielsweise mit Hilfe eines Werkzeugs durchbrochen, so liegt das ausgehärtete Material dort frei und kann zur Verbindung wie oben dargestellt vorteilhaft genutzt werden.If the wall of the hybrid support ring is broken through at this point, for example with the help of a tool, the hardened material is exposed there and can be used advantageously for the connection as shown above.

In einer anderen vorteilhaften Ausführung der Erfindung kann vorgesehen sein, dass die Schale derartig ausgebildet ist, dass diese weitgehend geschlossen geformt ist und nur eine kleine Öffnung zum Einfüllen des aushärtenden Materials aufweist. Dies kann in einer Fortbildung derart ausgeführt sein, dass nur eine Öffnung zum befüllen des Volumens der Schale und eine Öffnung zur Entlüftung des Volumens der Schale vorgesehen ist.In another advantageous embodiment of the invention, it can be provided that the shell is designed in such a way that it is shaped to be largely closed and only has a small opening for filling in the hardening material. In a further development, this can be carried out in such a way that only one opening is provided for filling the volume of the bowl and one opening for venting the volume of the bowl.

In einer weiteren vorteilhaften Ausführung der Erfindung kann aber auch vorgesehen sein, dass die Schale derartig ausgebildet ist, dass diese weitgehend offen ist, also das mit dem aushärtenden Material zu füllende Volumen zur Bildung des Hybrid-Auflagerings nur teilweise begrenzt. Bevorzugt ist dabei vorgesehen, wenn die Schale so geformt ist, dass diese zur Innenseite des Schachtbauwerks hin orientiert ist, um so die aggressiven Medien aus dem Schachtbauwerk nicht mit dem ausgehärteten Material des Hybrid-Auflagerings in Kontakt kommen zu lassen. Entsprechend sind weitere begrenzende Wände bei der Herstellung des Hybrid-Auflagerings dann durch beispielsweise wiederverwendbare Schalungen, zum Beispiel solchen aus Metall, Holz oder Polymermaterial, zu bilden.In a further advantageous embodiment of the invention, it can also be provided that the shell is designed in such a way that it is largely open, i.e. the volume to be filled with the hardening material to form the hybrid support ring is only partially limited. It is preferred if the shell is shaped in such a way that it is oriented towards the inside of the shaft structure in order to prevent the aggressive media from the shaft structure from coming into contact with the hardened material of the hybrid support ring. Accordingly, further delimiting walls must then be formed during the production of the hybrid support ring using, for example, reusable formwork, for example those made of metal, wood or polymer material.

Als günstig kann sich bei der vorliegenden Erfindung erweisen, wenn vorgesehen ist, dass Aufnahmemittel vorgesehen sind, um den mit der Schale zu bildenden Hybrid-Auflagering aufnehmen zu können, um diesen beispielsweise zu bewegen, auf- und abzuladen, zu positionieren, zu versetzen und dergleichen. Solche Aufnahmemittel können Ösen umfassen, die im Bereich der Wand der Schale ausgebildet sind. Es kann auch vorgesehen sein, dass die Wand der Schale an geeigneten Stellen Durchbrüche aufweist, um an diesen Stellen beispielsweise ein Aufnahmemittel in Form einer Metallstange oder eines Metallseils, das fest im ausgehärteten Material des Hybrid-Auflagerings eingebettet ist, aus der Schale herausragen zu lassen. Bewährt hat sich im Erfindungszusammenhang, wenn vorgesehen ist, wenigstens drei solche Ösen, Metallstangen oder Metallseile anzuordnen, da dies das Aufnehmen des Hybrid-Auflagerings erheblich vereinfacht.In the present invention, it can prove to be advantageous if it is provided that receiving means are provided in order to be able to receive the hybrid support ring to be formed with the shell, for example in order to move it, load and unload it, position it, move it and the like. Such receiving means can include eyelets which are formed in the area of the wall of the shell. It can also be provided that the wall of the shell has openings at suitable points in order to allow a receiving means in the form of a metal rod or a metal rope, which is firmly embedded in the hardened material of the hybrid support ring, to protrude from the shell at these points. In the context of the invention, it has proven useful to arrange at least three such eyelets, metal rods or metal cables, as this considerably simplifies the process of receiving the hybrid support ring.

Es ist gemäß der Erfindung vorgesehen, dass die erste Auflagefläche eine Oberfläche aufweist, die strukturiert ist, um ein gute Anbindung eines aushärtenden Materials, wie beispielsweise Mörtel, zur Befestigung der an der ersten Auflagefläche anzuordnenden Abdeckung zu gewährleisten. Hierzu weist die Oberfläche der ersten Auflagefläche eine Vielzahl von Vertiefungen und Erhöhungen auf.According to the invention, it is provided that the first support surface has a surface that is structured to ensure good bonding of a hardening material, such as mortar, for fastening the cover to be arranged on the first support surface. For this purpose, the surface of the first support surface has a large number of depressions and elevations.

Es kann dazu auch vorgesehen sein, diese Oberfläche durch einen Strahlprozess, beispielsweise einen Sandstrahlprozess, aufzurauhen.For this purpose, provision can also be made to roughen this surface using a blasting process, for example a sandblasting process.

Auch kann die Oberfläche der ersten Auflagefläche durch physikalische und / oder chemische Behandlung hydrophil gemacht werden, indem die Oberfläche beispielsweise mit Hilfe einer Flamme und / oder eines Plasmas und / oder einer Laserstrahlung und / oder einer UV-Strahlung und / oder eines Ätzprozesses und oder eines Haftvermittlerauftrags aktiviert wird.The surface of the first support surface can also be made hydrophilic by physical and/or chemical treatment, for example by treating the surface with the aid of a flame and/or a plasma and/or laser radiation and/or UV radiation and/or an etching process and or of an adhesion promoter order is activated.

Es ist ebenso möglich, die Oberfläche der ersten Auflagefläche durch dort aus der Polymermatrix herausragende Fasern, insbesondere Mineralfasern und / oder Glasfasern und / oder Metallfasern, oder durch geeignete Füllstoffe zur verbesserten Anbindung des aushärtenden Material - wie vorstehend beschrieben - zu optimieren.It is also possible to optimize the surface of the first support surface by fibers protruding from the polymer matrix, in particular mineral fibers and/or glass fibers and/or metal fibers, or by suitable fillers for improved binding of the hardening material - as described above.

Die vorstehend genannten Möglichkeiten zur Modifikation der Oberfläche der ersten Auflagefläche können auch in Kombination miteinander vorgesehen sein.The above-mentioned options for modifying the surface of the first support surface can also be provided in combination with one another.

Zur weiteren Verbesserung der vorliegenden Erfindung kann darüber hinaus noch vorgesehen sein, dass an der ersten Auflagefläche entlang wenigstens eines Abschnittes des die erste Auflagefläche zum Durchbruch hin begrenzenden Randes eine axiale Wand geringer Höhe ausgebildet ist, die es leicht ermöglicht, auf der ersten Auflagefläche ein aushärtendes Material, wie beispielsweise Mörtel, zur Befestigung der an der ersten Auflagefläche anzuordnenden Abdeckung aufzutragen und dieses Material beispielsweise mit einer Kelle unter Nutzung der Oberkante dieser Wand glattzuziehen, wodurch einerseits eine gleichmäßige Dicke des Materials auf der ersten Auflagefläche hergestellt werden kann und andererseits vermieden wird, dass Material in den Durchbruch unerwünscht hineinfließt.To further improve the present invention, it can also be provided that an axial wall of small height is formed on the first support surface along at least a section of the edge delimiting the first support surface towards the breakthrough, which makes it easy to harden on the first support surface Material, such as mortar, for attaching the to the first support surface to apply the cover to be arranged and to pull this material smooth, for example with a trowel using the upper edge of this wall, which on the one hand allows a uniform thickness of the material to be produced on the first support surface and on the other hand prevents material from flowing undesirably into the opening.

In einer weiteren vorteilhaften Ausführung der Erfindung kann vorgesehen sein, dass der Hybrid-Auflagering eine Identifikationsvorrichtung aufweist, die entweder in der Schale des Hybrid-Auflagerings oder in der ausgehärteten Masse des Hybrid-Auflagerings angeordnet ist. Eine solche Identifikationsvorrichtung kann ein RFID-Chip sein, mit dem der Hybrid-Auflagering eindeutig identifizierbar ist und auf diese Weise die Verwaltung eines Fluidsystems mit einem derartigen Hybrid-Auflagering wesentlich vereinfacht.In a further advantageous embodiment of the invention, it can be provided that the hybrid support ring has an identification device which is arranged either in the shell of the hybrid support ring or in the hardened mass of the hybrid support ring. Such an identification device can be an RFID chip with which the hybrid support ring can be clearly identified and in this way significantly simplifies the management of a fluid system with such a hybrid support ring.

Die Schale gemäß vorliegender Erfindung kann in einer günstigen Ausbildung so geformt sein, dass sie an ihrem äußeren Rand eine senkrecht radial nach außen wegstehende Wand aufweist, die beim Einbau in ein Schachtbauwerk zumindest partiell lastabtragend wirkt und so für die Herstellung eines verbesserten Hybrid-Auflagerings zur Verfügung steht.In a favorable embodiment, the shell according to the present invention can be shaped in such a way that it has a vertical, radially outwardly projecting wall on its outer edge, which has at least a partial load-bearing effect when installed in a shaft structure and is thus used for the production of an improved hybrid support ring Available.

Bei der vorliegenden Erfindung kann sich als sehr vorteilhaft erweisen, wenn vorgesehen ist, dass die Schale aus einem Polymermaterial, das thermoplastisch oder duroplastisch ist, oder aus einem Metall besteht oder ein solches enthält.In the present invention, it can prove to be very advantageous if it is provided that the shell consists of or contains a polymer material that is thermoplastic or thermoset, or of a metal.

Bevorzugt ist in diesem Zusammenhang ein Polyolefin, wie ein Polypropylen oder ein Polyethylen oder ein Polybutylen oder ein Polyvinylchlorid, aus dem die Schale besteht oder welches die Schale enthält.In this context, preference is given to a polyolefin, such as a polypropylene or a polyethylene or a polybutylene or a polyvinyl chloride, which the shell consists of or which contains the shell.

Die vorstehend genannten Polymermaterialien sind inert, langlebig, korrosionsbeständig, leicht formbar, günstig und verfügbar.The above-mentioned polymer materials are inert, durable, corrosion-resistant, easily moldable, inexpensive and available.

Durch die Trennung der ausgehärteten Masse in der Schale, also beispielsweise dem Beton, durch das Polymermaterial der Wand der Schale von den korrosiven Gasen im Schachtbauwerk kann es zu keinem korrosiven Angriff des Betons kommen, so dass die vorstehend beschriebenen Nachteile des Standes der Technik überwunden werden können.By separating the hardened mass in the shell, for example the concrete, from the corrosive gases in the shaft structure by the polymer material of the wall of the shell, no corrosive attack on the concrete can occur, so that the disadvantages of the prior art described above are overcome can.

Die Schale der vorliegenden Erfindung kann in einem Polymerformgebungsprozess, wie einem Spritzgussprozess oder einem Rotationsgießprozess oder einem Rotationssinterprozess oder einem Pressprozess oder einem Tiefziehprozess oder einem Extrusionsblasprozess oder einem additiven Fertigungsprozess, wie einem 3D-Druckprozess, oder einer Kombination der vorstehend aufgeführten Prozesse hergestellt sein.The shell of the present invention may be manufactured in a polymer molding process, such as an injection molding process, or a rotational molding process, or a rotational sintering process, or a pressing process, or a deep drawing process, or an extrusion blow molding process, or an additive manufacturing process, such as a 3D printing process, or a combination of the processes listed above.

Die vorstehend genannten Prozesse sind geeignet, eine Schale gemäß vorliegender Erfindung in großer Stückzahl reproduzierbar, maßhaltig und kostengünstig herzustellen.The above-mentioned processes are suitable for producing a shell according to the present invention in large quantities, reproducibly, dimensionally and cost-effectively.

Alternativ kann vorgesehen sein, dass die Schale ganz oder teilweise unter Verwendung eines generativen Fertigungsverfahrens, beispielsweise durch ein 3-D-Druckverfahren, hergestellt ist.Alternatively, it can be provided that the shell is manufactured entirely or partially using a generative manufacturing process, for example a 3D printing process.

Hierzu kann mit Vorteil ein datenverarbeitungsmaschinenlesbares dreidimensionales Modell für die Herstellung genutzt werden.For this purpose, a data processing machine-readable three-dimensional model can advantageously be used for production.

Die Erfindung umfasst auch ein Verfahren zur Erzeugung eines datenverarbeitungsmaschinenlesbaren dreidimensionalen Modells zur Verwendung in einem Herstellungsverfahren für eine Schale. Hierbei umfasst das Verfahren insbesondere auch die Eingabe von Daten, die eine Schale darstellen, in eine Datenverarbeitungsmaschine und die Nutzung der Daten, um ein Schale als dreidimensionales Modell darzustellen, wobei das dreidimensionale Modell geeignet ist zur Nutzung bei der Herstellung einer Schale.

In this case, the method also includes, in particular, the input of data representing a shell into a data processing machine and the use of the data to represent a shell as a three-dimensional model, the three-dimensional model being suitable for use in the production of a shell. Also included in the method is a technique in which the input data of one or more 3D scanners, which function either on contact or contactless, in the latter case energy is released onto a shell and the reflected energy is received, and wherein a virtual three-dimensional Model of a shell is generated using computer-aided design software.

Alle Wände 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7 und 2.8 ziehen sich in gleicher Weise um die Schale, so dass diese gegenüber der Achse A rotationssymmetrisch ausgebildet ist.All walls 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7 and 2.8 extend around the shell in the same way, so that it is rotationally symmetrical with respect to axis A.

Es versteht sich, dass auch andere Ausgestaltungsmöglichkeiten der Schale 1, insbesondere solche mit anderen Anordnungen von Wänden 2, möglich sind.It goes without saying that other design options for the shell 1, in particular those with other arrangements of walls 2, are also possible.

In der Fig. 3 ist eine perspektivische teilweise geschnittene Ansicht eines Hybrid-Auflagerings 10 gezeigt.In the Fig. 3 a perspective, partially sectioned view of a hybrid support ring 10 is shown.

Die Bezugszeichen der Fig. 3 entsprechen denen aus den vorherigen Figuren.The reference numbers of the Fig. 3 correspond to those from the previous figures.

Der Hybrid-Auflagering 10 ist dadurch gebildet, dass in das Volumen 3 der Schale 1 ein aushärtendes Material eingefüllt ist, und dieses aushärtende Material zu einem ausgehärteten Material 9 ausgehärtet ist. Das ausgehärtete Material 9 füllt das Volumen 3 der Schale 1 bis zur Oberkante der Schale 1 auf.The hybrid support ring 10 is formed in that a hardening material is filled into the volume 3 of the shell 1 and this hardening material is hardened into a hardened material 9. The hardened material 9 fills the volume 3 of the shell 1 up to the upper edge of the shell 1.

Es ist aber auch möglich, dass das Volumen 3 der Schale 1 nur teilweise mit dem aushärtenden Material aufgefüllt wird.However, it is also possible that the volume 3 of the shell 1 is only partially filled with the hardening material.

Am Hybrid-Auflagering 10 sind Auflageflächen ausgebildet, wobei eine erste Auflagefläche 6.1 und eine zweite Auflagefläche 6.2 vorgesehen sind. Die erste Auflagefläche 6.1 und die zweite Auflagefläche 6.2 sind etwa parallel zueinander ausgerichtet. Sowohl die erste Auflagefläche 6.1 wie auch die zweite Auflagefläche 6.2 sind ringförmig umlaufend am Hybrid-Auflagering 10 ausgebildet. Die erste Auflagefläche 6.1 ist kleiner als die zweite Auflagefläche 6.2 des Hybrid-Auflagerings 10. Beim Einbau des Hybrid-Auflagerings 10 in ein Schachtbauwerk 30 ist vorgesehen, dass der Hybrid-Auflagering 10 so positioniert ist, dass er mit der zweiten Auflagefläche 6.2 auf ein Auflager 34, das als Bettung ausgebildet ist und beispielsweise in Form einer Betonplatte oder eines Bettes aus Splitt besteht, aufgelegt wird und an seiner ersten Auflagefläche 6.1 die Abdeckung 35 angeordnet wird, die den Abschluss zur Geländeoberkante GOK bildet, was in Fig. 6 detailliert gezeigt ist.Support surfaces are formed on the hybrid support ring 10, with a first support surface 6.1 and a second support surface 6.2 being provided. The first support surface 6.1 and the second support surface 6.2 are aligned approximately parallel to one another. Both the first support surface 6.1 and the second support surface 6.2 are formed in an annular manner on the hybrid support ring 10. The first support surface 6.1 is smaller than the second support surface 6.2 of the hybrid support ring 10. When installing the hybrid support ring 10 in a shaft structure 30, it is provided that the hybrid support ring 10 is positioned so that it is in contact with the second support surface 6.2 Support 34, which is designed as a bedding and consists, for example, in the form of a concrete slab or a bed of grit, is placed and the cover 35 is arranged on its first support surface 6.1, which forms the end to the upper edge of the terrain GOK, which in Fig. 6 is shown in detail.

In vorteilhafter Weise kann nach dem Einfüllen des aushärtenden Materials in das Volumen 3 der Schale 1 eine glatte zweite Auflagefläche 6.2 dadurch hergestellt werden, dass das aushärtende Material durch Abziehen und Glattziehen mit beispielsweise einer Kelle entlang der oberen freien Ränder der die Schale 1 begrenzenden Wände 2 an deren zweiten Ende E2 erfolgt.Advantageously, after filling the hardening material into the volume 3 of the shell 1, a smooth second support surface 6.2 can be produced by pulling the hardening material off and smoothing it with, for example, a trowel along the upper free edges of the walls 2 delimiting the shell 1 at the second end E2 occurs.

Der Hybrid-Auflagering ist rotationssymmetrisch ausgebildet.The hybrid support ring is designed to be rotationally symmetrical.

In der Ansicht gemäß Fig. 4 ist die Schale 1, die zur Bildung des Hybrid-Auflagerings 10 herangezogen ist, gezeigt, weiterhin die erste Auflagefläche 6.1 am Hybrid-Auflagering 10. Der Hybrid-Auflagering 10 weist zumindest abschnittsweise an seiner Außenoberfläche eine Kegelabschnittsfläche auf, was ihn besonders vorteilhaft stabilisiert und wodurch die im Einbauzustand auf ihn einwirkenden Kräfte in günstiger Weise nach unten verteilt weitergeleitet werden.According to the view Fig. 4 the shell 1, which is used to form the hybrid support ring 10, is shown, as well as the first support surface 6.1 on the hybrid support ring 10. The hybrid support ring 10 has, at least in sections, a conical section surface on its outer surface, which stabilizes it particularly advantageously and whereby the forces acting on it when installed are distributed downwards in a favorable manner.

In der Fig. 5 ist ein Hybrid-Auflagering 10 in einer perspektivischen Ansicht in einer zweiten Ausführungsart gezeigt.In the Fig. 5 is a hybrid support ring 10 shown in a perspective view in a second embodiment.

Die Bezugszeichen der Fig. 5 entsprechen denen aus den vorherigen Figuren.The reference numbers of the Fig. 5 correspond to those from the previous figures.

Die zur Herstellung des Hybrid-Auflagerings 10 verwendete Schale 1 ist dabei so gestaltet, dass Durchbrüche 5 in der ersten Auflagefläche 6.1 der Schale 1 angeordnet sind, sodass bei der Herstellung des Hybrid-Auflagerings 10 durch Füllen des Volumens 3 der Schale 1 mit einem aushärtenden Material und dem Aushärten des aushärtenden Materials zum ausgehärteten Material 9 dieses ausgehärtete Material 9 in die Durchbrüche 5 eindringt bzw. an den Durchbrüchen 5 der Schale 1 ansteht und dort freiliegt.The shell 1 used to produce the hybrid support ring 10 is designed in such a way that openings 5 are arranged in the first support surface 6.1 of the shell 1, so that during the production of the hybrid support ring 10 by filling the volume 3 of the shell 1 with a hardening material and the hardening of the hardening material to the hardened material 9, this hardened material 9 penetrates into the openings 5 or is present at the openings 5 of the shell 1 and is exposed there.

Die Durchbrüche 5 der Schale 1 an der ersten Auflagefläche 6.1 sind kreisrund ausgebildet und in einer Vielzahl angeordnet. Hierbei ist vorgesehen, dass der Abstand eines Durchbruchs 5 zu seinen beiden jeweiligen Nachbarn stets gleichbemessen ist.The openings 5 of the shell 1 on the first support surface 6.1 are circular and arranged in a large number. It is provided here that the distance between an opening 5 and its two respective neighbors is always the same.

In der Fig. 6 ist eine geschnittene Ansicht eines Schachtbauwerks 30 gezeigt.In the Fig. 6 a sectional view of a shaft structure 30 is shown.

Die Bezugszeichen der Fig. 6 entsprechen denen aus den vorherigen Figuren.The reference numbers of the Fig. 6 correspond to those from the previous figures.

Das Schachtbauwerk 30 ist im Erdreich eingebaut und umfasst ein Schachtunterteil 31, welches eingerichtet ist, ein Fluid zu transportieren, wozu beispielsweise ein Gerinne und Anschlüsse für Rohre vorgesehen sind, einen auf das Schachtunterteil 31 fluiddicht aufgesetzten Schachtring 32, einen auf den Schachtring fluiddicht aufgesetzten Schachtkonus 33, und einen Hybrid-Auflagering 10, der fluiddicht mit dem Schachtkonus 33 verbunden ist und seinerseits auf ein Auflager 34, das vorliegend als Betonplatte ausgebildet ist, aufliegt.The shaft structure 30 is installed in the ground and comprises a lower shaft part 31, which is set up to transport a fluid, for which purpose, for example, a channel and connections for pipes are provided, a shaft ring 32 which is placed on the lower shaft part 31 in a fluid-tight manner, and a shaft cone which is placed on the shaft ring in a fluid-tight manner 33, and a hybrid support ring 10, which is connected in a fluid-tight manner to the shaft cone 33 and in turn rests on a support 34, which in the present case is designed as a concrete slab.

Mit dem Hybrid-Auflagering 10 ist fluiddicht eine Abdeckung 35 verbunden, die in an sich bekannter Weise eine Abdeckung zur Geländeoberkante GOK darstellt, die beispielsweise in Form einer Platte oder eines Gitters ausgebildet ist. Die Oberseite der Abdeckung 35 schließt hierbei mit der Geländeoberkante GOK ab.A cover 35 is fluid-tightly connected to the hybrid support ring 10 and, in a manner known per se, represents a cover for the upper edge of the terrain GOK, which is designed, for example, in the form of a plate or a grid. The top of the cover 35 ends with the top edge of the terrain GOK.

In der Fig. 6 ist ein Detail X in einer vergrößerten Darstellung gezeigt.In the Fig. 6 A detail X is shown in an enlarged view.

Der Hybrid-Auflagering 10 weist eine erste Auflagefläche 6.1 auf, auf der die Abdeckung 35 fluiddicht aufgelegt und verbunden ist. Hilfreich ist dabei, wenn vorgesehen ist, dass zwischen der ersten Auflagefläche 6.1 des Hybrid-Auflagerings 10 und der Unterseite der Abdeckung 35, die auf die erste Auflagefläche 6.1 aufzulegen ist, eine Mörtelschicht aufgetragen wird, um eine fluiddichte Anbindung der Abdeckung 35 an den Hybrid-Auflagering 10 herzustellen.The hybrid support ring 10 has a first support surface 6.1, on which the cover 35 is placed and connected in a fluid-tight manner. It is helpful if it is provided that a layer of mortar is applied between the first support surface 6.1 of the hybrid support ring 10 and the underside of the cover 35, which is to be placed on the first support surface 6.1, in order to ensure a fluid-tight connection of the cover 35 to the hybrid -Produce support ring 10.

Soweit ein Hybrid-Auflagering 10 der zweiten Ausführung gemäß Fig. 5 eingesetzt wird, kann die Mörtelschicht auf der ersten Auflagefläche 6.1 des Hybrid-Auflagerings 10 mit dem ausgehärteten Material 9, das in oder an den Durchbrüchen 5 ansteht und dort freiliegt in Kontakt kommen und hier eine besonders feste Verbindung mit diesem eingehen. Hierdurch kann eine verschiebesichere Befestigung der Abdeckung 35 an dem Hybrid-Auflagering 10 sichergestellt werden.As far as a hybrid support ring 10 according to the second embodiment Fig. 5 is used, the mortar layer can be on the first support surface 6.1 of the hybrid support ring 10 with the hardened material 9, which is in or on the openings 5 and is exposed there Come into contact and form a particularly strong connection with this person. This can ensure that the cover 35 is secured against displacement on the hybrid support ring 10.

Der Hybrid-Auflagering 10 ist mit seiner zweiten Auflagefläche 6.2 auf dem Auflager 34 in Form einer Betonplatte aufgelegt. Auch hier kann es sich als sehr hilfreich erweisen, wenn vorgesehen ist, dass zwischen dem Auflager 34 in Form einer Betonplatte und der zweiten Auflagefläche 6.2 des Hybrid-Auflagerings 10 eine Mörtelschicht angeordnet wird, um eine feste und insbesondere verschiebesichere Anordnung des Hybrid-Auflagerings 10 auf dem Auflager 34 sicherzustellen.The hybrid support ring 10 is placed with its second support surface 6.2 on the support 34 in the form of a concrete slab. Here too, it can prove to be very helpful if it is provided that a layer of mortar is arranged between the support 34 in the form of a concrete slab and the second support surface 6.2 of the hybrid support ring 10 in order to ensure a firm and, in particular, shift-proof arrangement of the hybrid support ring 10 on the support 34 to ensure.

Durch den Durchgang 4 des Hybrid-Auflagerings 10 kann Wasser in das Schachtbauwerk 30 von der Geländeoberkante GOK her einströmen, auch ist das Innere des Schachtbauwerks 30 durch den Durchgang 4 für Inspektionen, Wartungen, Reinigungsarbeiten und Reparaturen begehbar.Through the passage 4 of the hybrid support ring 10, water can flow into the shaft structure 30 from the upper edge of the GOK, and the interior of the shaft structure 30 can also be accessed through the passage 4 for inspections, maintenance, cleaning work and repairs.
