Description

Die Erfindung betrifft eine Abdichtungsvorrichtung einer Abdeckung aus einem Lagerkörper und einem im Lagerkörper abgestützten Deckel zum Abdichten des Deckels im Wandbereich seiner Lagerstelle und in dem Wandbereich der Lagerstelle des Lagerkörpers, wobei in diesen Wandbereichen der Deckel und der Lagerkörper aneinander anliegen und durch eine Weichdichtung abgedichtet sind.The invention relates to a sealing device for a cover comprising a bearing body and a cover supported in the bearing body for sealing the cover in the wall area of its bearing point and in the wall area of the bearing point of the bearing body, the lid and the bearing body abutting one another in these wall areas and being sealed by a soft seal .

Die Anodnung eines Deckels in einer Boden-oder einer Wandpartie wird überall dort vorgesehen, wo eine Öffnung für den Zugang zu einer von der Boden- oder Wandabdeckung abgedeckten Stelle erforderlich ist. Eine besonders häufige, bekannte Anordnung eines Deckels liegt bei Schachtabdeckungen vor. Die Abdeckung wird hierbei im wesentlichen durch einen im Boden abgestützten Abdeckrahmen gebildet, in welchem eine Öffnung als Zugang zu dem darunterliegenden Schacht ausgespart ist. Diese Öffnung wird bei Nichtbenützung durch einen Deckel abgedeckt, welcher mit seiner Lagerstelle sich auf einer, die Öffnung umgebende Lagerstelle abstützt. Bei diesen Lagerstellen handelt es sich um Wandpartien des Deckels und des Abdeckrahmens, die je nach dem Anwendungsfall bearbeitet oder roh sind. Je nach der Form der Öffnung weist auch der Deckel eine entsprechende Form auf. Diese kann kreisförmig, oval, quadratisch, rechteckig oder von beliebiger Form sein.The arrangement of a cover in a floor or wall section is provided wherever an opening is required for access to a location covered by the floor or wall cover. A particularly common, known arrangement of a cover is in the case of manhole covers. The cover is essentially formed by a cover frame supported in the floor, in which an opening is recessed as an access to the underlying shaft. When not in use, this opening is covered by a cover which, with its bearing point, is supported on a bearing point surrounding the opening. These bearings are wall parts of the cover and the cover frame, which are machined or raw depending on the application. Depending on the shape of the opening, the lid also has a corresponding shape. This can be circular, oval, square, rectangular or of any shape.

An solche Abdeckungen werden verschiedene Anforderungen gestellt, Soll der Deckel spielfrei und kippfrei in der Abdeckung bzw. im Abdeckrahmen liegen, werden die Wandpartien der Lagerstellen bearbeitet. In bestimmten Anwendungsfällen wird verlangt, dass der Deckel gas- und flüssigkeitsdicht die Öffnung in der Abdeckung abschliesst.Various requirements are placed on such covers. If the cover is to lie in the cover or in the cover frame free of play and without tilting, the wall parts of the bearing points are machined. In certain applications, the cover is required to be gas-tight and liquid-tight to close the opening in the cover.

Die Erfindung betrifft den letztgenannten Anwendungsfall, bei welchem zwischen dem Deckel und dem Abdeckrahmen Dichtheit und Spielfreiheit verlangt wird.The invention relates to the latter application, in which tightness and freedom from play is required between the cover and the cover frame.

Es ist bekannt (GB-PS 132 684), die Dichtheit einer Abdeckung dadurch zu erreichen, dass zwischen dem Lagerkörper und dem Deckel ein Spalt vorgesehen wird, der mit Fett gefüllt ist. Dieser Spalt kann von aussen beobachtet und damit die Vollständigkeit der Abdichtung festgestellt werden. Für die Erhaltung des Spaltes wird an der Auflagefläche des Deckels ein Zentrierwulst vorgesehen, was einen zusätzlichen Materialaufwand bedeutet. Da jedoch die Umfangsflächen des Lagerkörpers und des Deckels durch den Spalt voneinander getrennt sind, ist der Fettbedarf verhältnismässig hoch, da bei jedem Öffnen die Fettfüllung neu hergestellt werden muss. Zudem ist bei dieser Anordnung von Lagerkörper und Deckel ein gegenseitiges Bewegen bei der Verkehrsbelastung unvermeidlich und zieht einen Fettverlust nach, so dass die zuverlässige Abdichtung nicht gewährleistet ist. Wegen des offenen Spaltes kann auch das Fett austrocknen und seine Dichtfunktion einbüssen.It is known (GB-PS 132 684) to achieve the tightness of a cover by providing a gap between the bearing body and the cover which is filled with grease. This gap can be observed from the outside and thus the completeness of the seal can be determined. To maintain the gap, a centering bead is provided on the contact surface of the cover, which means an additional material expenditure. However, since the circumferential surfaces of the bearing body and the cover are separated from one another by the gap, the grease requirement is relatively high, since the grease filling has to be produced anew each time it is opened. In addition, with this arrangement of the bearing body and cover, mutual movement when the traffic load is inevitable and causes fat loss, so that reliable sealing is not guaranteed. Because of the open gap, the fat can also dry out and lose its sealing function.

Soll eine langdauernde Dichtwirkung erreicht werden, ist es bekannt, zur Erreichung einer guten Abdichtung zwischen dem Deckel und seiner Lagerung einen Weichdichtungsring anzuordnen (EP 0 005 851 A1). Damit aber der Dichtungsring nicht durch auf den Deckel wirkende Lasten überbeansprucht wird, muss der Deckel zusätzlich an der Lagerung abgestützt und festgeschraubt werden, was einen verhältnismässig grossen Aufwand bedeutet. Werden solche Dichtungsringe bei unbearbeiteten Lagerstellen angeordnet, kann wegen der vorhandenen Masstoleranzen keine zuverlässige Abdichtung erreicht werden.If a long-lasting sealing effect is to be achieved, it is known to arrange a soft sealing ring between the cover and its mounting in order to achieve a good seal (EP 0 005 851 A1). However, so that the sealing ring is not overstressed by loads acting on the cover, the cover must also be supported on the bearing and screwed tight, which means a relatively great effort. If such sealing rings are arranged at unprocessed bearings, reliable sealing cannot be achieved due to the existing dimensional tolerances.

Hier setzt die Erfindung ein, der die Aufgabe zugrundeliegt, eine Dichtungsvorrichtung der eingangs beschriebenen Art so auszugestalten, dass die Dichtheit zwischen dem Deckel und dem Lagerkörper zuverlässig erreicht und für längere Zeit erhalten bleibt, unabhängig davon ob die Lagerstellen roh oder bearbeitet sind, und dass keine zusätzlichen Materialpartien vorgesehen werden müssen.This is where the invention comes in, which is based on the object of designing a sealing device of the type described at the outset in such a way that the tightness between the cover and the bearing body is reliably achieved and maintained for a long time, regardless of whether the bearing points are raw or machined, and that no additional material batches have to be provided.

Diese Aufgabe wird gemäss der Erfindung dadurch gelöst, dass in einem Teil der aneinanderliegenden Wandbereiche des Deckels und des Lagerkörpers eine Ausnehmung angeordnet ist, die sich ringförmig längs der Wandbereiche erstreckt und mit einer fliessfähigen Dichtungsmasse gefüllt sowie mit zwei mit Abstand angeordneten, an der Aussenseite des Deckels oder des Lagerkörpers mündenden Öffnungen verbunden ist.This object is achieved according to the invention in that a recess is arranged in a part of the adjoining wall areas of the cover and the bearing body, which extends in a ring along the wall areas and is filled with a flowable sealing compound and with two spaced apart on the outside of the Lid or the bearing body opening openings is connected.

Die Abdeckung nach Fig. 2 setzt sich aus einem in Fig. 1 dargestellten Deckel 1 und einem Abdeckrahmen oder Lagerkörper 2 zusammen. Eine solche Abdeckung dient beispielsweise zum Abdecken eines Vertikalschachtes im Boden. Meistens bestehen die Teile der Abdeckung aus Metall, beispielsweise aus Gusseisen. Der Deckel 1 weist eine Ausnehmung 3 auf, in die ein Füllmaterial, z. B. Beton eingebracht wird. Der Deckel kann jedoch auch ohne Ausnehmung ausgeführt sein, siehe Fig. 9 und 10. Aber auch andere Materialien kommen zur Anwendung, z. B. Leichtmetall oder armierter Beton.2 is composed of a cover 1 shown in FIG. 1 and an Ab cover frame or bearing body 2 together. Such a cover is used, for example, to cover a vertical shaft in the floor. Most of the parts of the cover are made of metal, such as cast iron. The lid 1 has a recess 3 into which a filling material, for. B. concrete is introduced. The lid can, however, also be designed without a recess, see FIGS. 9 and 10. B. light metal or reinforced concrete.

Der Lagerkörper 2 weist eine, eine Öffnung 4 umgebende Lagerstelle in Form eines Flansches 5 auf. Daran anschliessend folgt eine Wandpartie 6, die mit einer Wandpartie 7 des Deckels 1 zusammenwirkt, der sich mit seiner Lagerstelle an dem die Lagerstelle des Lagerkörpers 2 bildenden Flansch 5 abstützt.The bearing body 2 has a bearing point in the form of a flange 5 surrounding an opening 4. This is followed by a wall section 6, which cooperates with a wall section 7 of the cover 1, which is supported with its bearing point on the flange 5 forming the bearing point of the bearing body 2.

In der Wandpartie 7 des Deckels 1 ist eine am Aussenumfang angeordnete Nut 10 eingearbeitet. Die Nut 10, siehe Fig. 1, ist mit der Aussenseite durch eine Einfüllöffnung 11 und mit einer Entlüftungsöffnung 12 verbunden. Zweckmässig liegt die Entlüftungsöffnung 12 an der, der Einfüllöffnung 11 am weitesten entfernten Stelle. Durch die Einfüllöffnung 11 wird eine Dichtungsmasse 13 eingefüllt, die die Nut 10 auf ihrer gesamten Länge ausfüllt und schliesslich an der Entlüftungsöffnung 12 austritt. Zweckmässig wird hierbei die Dichtungsmasse 13 mit Druck eingepresst, um ein vollständiges Ausfüllen der Nut 10 zu erreichen.A groove 10 arranged on the outer circumference is incorporated in the wall part 7 of the cover 1. The groove 10, see FIG. 1, is connected to the outside through a filling opening 11 and with a ventilation opening 12. The ventilation opening 12 expediently lies at the point furthest away from the filling opening 11. A sealing compound 13 is filled through the filling opening 11, which fills the groove 10 over its entire length and finally emerges at the ventilation opening 12. The sealing compound 13 is expediently pressed in with pressure in order to achieve a complete filling of the groove 10.

Die Dichtungsmasse 13 muss verschiedenen Anforderungen genügen: Sie muss zähflüssig und zusammenhängend sein und darf im Laufe der Zeit ihre Dichteigenschaft nicht verlieren. Hierzu eignen sich einige Kunststoffe, beispielsweise Siliconkautschuk. Damit der Deckel 1 auch nach Einbringen der Dichtungsmasse 13 geöffnet werden kann, wird an der Wandpartie 6 des Lagerkörpers 2 ein Trennmittel, beispielsweise Öl, aufgebracht. Die Nut 10 muss gegebenenfalls ebenfalls behandelt, beispielsweise mit einem Lösungsmittel gereinigt und mit einem Haftmittel belegt werden, insbesondere dann, wenn die Nut 10 maschinell eingearbeitet ist.The sealing compound 13 must meet various requirements: it must be viscous and coherent and must not lose its sealing property over time. Some plastics are suitable for this, for example silicone rubber. So that the cover 1 can also be opened after the sealing compound 13 has been introduced, a release agent, for example oil, is applied to the wall section 6 of the bearing body 2. If necessary, the groove 10 must also be treated, for example cleaned with a solvent and coated with an adhesive, in particular if the groove 10 is machined in.

Die Abdichtung des Deckels 1 gegenüber dem Lagerkörper 2 setzt nicht voraus, dass die Wandpartien 6, 7 bearbeitet sind, jedoch ist dies bei bestimmten Abdeckungen der Fall. Die Dichtungsmasse 13 kann jedoch auch in gleicher Weise bei Abdeckungen angewendet werden, bei denen die Wandpartien 6, 7 und auch die Nut 10 roh sind. Hierbei wird lediglich die Nut 10 mit einer Grundierung versehen, um damit das Fliessen der Dichtungsmasse 13 zu verbessern und gleichzeitig die Haftung der Fliessmasse zu erhöhen. Für die Grundierung können dieselben Mittel wie bei Grundanstrichen verwendet werden, wobei der Auftrag des Mittels in einem oder mehreren Anstrichen erfolgt.The sealing of the cover 1 with respect to the bearing body 2 does not presuppose that the wall parts 6, 7 have been machined, but this is the case with certain covers. However, the sealing compound 13 can also be used in the same way for covers in which the wall parts 6, 7 and also the groove 10 are raw. In this case, only the groove 10 is provided with a primer in order to improve the flow of the sealing compound 13 and at the same time to increase the adhesion of the flow compound. The same means as for base coats can be used for priming, with the application of the agent in one or more coats.

Ist die durch die Abdeckung abzudeckende Öffnung gross, siehe Fig. 3, können zwei oder mehr Deckel 1 im Lagerkörper 2 gelagert werden. Auch in diesem Fall kann eine einwandfreie Abdichtung durch Einpressen der genannten Dichtungsmasse erreicht werden. Für die Abdichtung der beiden anstossenden Deckelseiten kann entweder nur in einem Deckel eine Nut 10 vorgesehen werden, oder es werden zwei Nuten übereinanderliegend angeordnet und mit der am Umfang der Deckel 1 verlaufenden Nut verbunden. Gegebenenfalls muss im Bereich der beiden anstossenden Deckel noch eine zweite Entlüftungsöffnung vorgesehen werden, jedoch kann an dieser Stelle auch die Einfüllöffnung vorgesehen werden, während dann zwei gegenüberliegende Entlüftungsöffnungen vorgesehen sind.If the opening to be covered by the cover is large, see FIG. 3, two or more lids 1 can be stored in the bearing body 2. In this case too, a perfect seal can be achieved by pressing in the sealant mentioned. For sealing the two abutting cover sides, a groove 10 can either be provided in only one cover, or two grooves are arranged one above the other and connected to the groove running on the circumference of the cover 1. If necessary, a second ventilation opening must also be provided in the area of the two adjoining lids, but the filling opening can also be provided at this point, while two ventilation openings lying opposite each other are then provided.

Die Nut 10 kann, siehe Fig. 4, auch in der Wandpartie 6 des Lagerkörpers 2 angeordnet sein. Die Einfüllöffnung und die Entlüftungsöffnung sind in diesem Fall im Lagerkörper 2 angeordnet.The groove 10 can, see FIG. 4, also be arranged in the wall section 6 of the bearing body 2. In this case, the filling opening and the ventilation opening are arranged in the bearing body 2.

Nach der Ausführung nach Fig. 5 wird die Kante zwischen der Lagerstelle und der Wandpartie 7 des Deckels 1 angeschrägt, so dass eine Ausnehmung 14 auf den ganzen Umfang entsteht. Diese wird in gleicher Weise mit der Dichtungsmasse 13 gefüllt wie bei der Nut 10. Beim Entfernen des Deckels 1 verbleibt die Dichtung in der Ausnehmung 14. Das Einfüllen der Dichtmasse erfolgt wie bei allen andern Ausführungen immer in der Schliesslage des Deckels 1.5, the edge between the bearing point and the wall part 7 of the cover 1 is chamfered, so that a recess 14 is formed over the entire circumference. This is filled with the sealing compound 13 in the same way as for the groove 10. When the cover 1 is removed, the seal remains in the recess 14. As with all other designs, the sealing compound is always filled in the closed position of the cover 1.

Bei der Ausführung nach Fig. 6 ist die Ausnehmung eine Umfangsrille 15 zwischen der Lagerstelle im Flansch 5 und der Wandpartie 6 des Lagerkörpers 2.6, the recess is a circumferential groove 15 between the bearing point in the flange 5 and the wall part 6 of the bearing body 2.

Bei der Ausführung nach Fig. 7 und 8 weist die Ausnehmung dieselbe Form wie die Nut 10 in Fig. 2 auf. In Fig. 7 ist die Nut 10 an der Lagerstelle des Deckels 1 und bei der Ausführung nach Fig. 8 an der Lagerstelle des Lagerkörpers 2 eingearbeitet.7 and 8, the recess has the same shape as the groove 10 in FIG. 2. In Fig. 7 the groove 10 is incorporated at the bearing point of the cover 1 and in the embodiment according to Fig. 8 at the bearing point of the bearing body 2.

In Fig. 9 sind die Wandpartien 6, 7 des Deckels und des Lagerkörpers 2 geneigte Flächen. Die Ausnehmung ist in Form einer dreieckförmigen Rille 16 in der Wandpartie 6 des Deckels 1 oder in der Wandpartie 7 des Lagerkörpers 2, siehe Fig. 11, eingearbeitet. Der Vorteil der Form dieser Rille 16 besteht darin, dass dann, wenn der Deckel 1 und der Lagerkörper 2 Gussstücke sind, die Rille 16 ohne Kern im Formmaterial geformt werden kann, wenn die Bodenfläche 18 sich bis zur Wandpartie 6 erstreckt.In Fig. 9, the wall portions 6, 7 of the lid and the bearing body 2 are inclined surfaces. The recess is in the form of a triangular groove 16 in the wall section 6 of the cover 1 or in the wall section 7 of the bearing body 2, see FIG. 11. The advantage of the shape of this groove 16 is that if the cover 1 and the bearing body 2 are castings, the groove 16 can be formed without a core in the molding material if the bottom surface 18 extends to the wall part 6.

Bei der Ausführung nach Fig. 10 ist die Ausnehmung eine Profilrille 17 in den Lagerstellen des Deckels 1 und des Lagerkörpers 2.In the embodiment according to FIG. 10, the recess is a profile groove 17 in the bearing points of the cover 1 and the bearing body 2.

Mit den beschriebenen Abdeckungen kann in einfacher Weise eine vollständige Abdichtung des unter der Abdeckung liegenden Raumes gewährleistet werden. Die Abdichtung erfolgt in der Schliesslage des Deckels 1 dadurch, dass eine Ausnehmung 10, 14-17 mit einer Dichtungsmasse 13 gefüllt wird. Die Abdichtung schmiegt sich vollständig an den Querschnitt der Nut an und kompensiert dadurch Toleranzen des Deckels 1 und des Lagerkörpers 2. Auch wenn zwischen dem Deckel 1 und dem Lagerkörper 2 ein Spiel besteht, dringt die Dichtungsmasse nicht in solch enge Spalten ein, sondern nimmt seinen Weg in Richtung des geringeren Widerstandes. Wird der Dekkel 1 abgehoben, ist es zweckmässig, dass er wieder in derselben Lage in den Lagerkörper 2 eingesetzt wird. Gegebenenfalls muss für die Lage des Deckels 1 eine Markierung oder ein Lagenocken vorgesehen werden. Dadurch, dass die Dichtungsmasse 13 mit Druck in die Ausnehmung eingespresst wird, wird nicht nur eine gas-und flüssigkeitsdichte Abdichtung, sondern auch eine spielfreie und damit klapperfreie Auflage des Deckels 1 im Lagerkörper 2 erreicht.With the covers described, a complete sealing of the space under the cover can be ensured in a simple manner. Sealing takes place in the closed position of the cover 1 in that a recess 10, 14-17 is filled with a sealing compound 13. The seal conforms completely to the cross section of the groove and thereby compensates for tolerances of the cover 1 and the bearing body 2. Even if there is play between the cover 1 and the bearing body 2, the sealant does not penetrate into such narrow gaps, but takes its place Path towards less resistance. If the lid 1 is lifted, it is appropriate that it is again inserted in the same position in the bearing body 2. If necessary, a mark or a layer cam must be provided for the position of the cover 1. Because the sealing compound 13 is pressed into the recess with pressure, not only is a gas and liquid-tight seal achieved, but also a play-free and thus rattle-free support of the cover 1 in the bearing body 2.

In den Figuren ist der Lagerkörper aus Platzgründen nur als Rahmen dargestellt. Der Deckel 1 kann jedoch auch Teil einer Abdeckung sein, bei der der Lagerkörper 2 zur Abdeckung einer grösseren Fläche dient. Eine solche Abdeckung kann nicht nur für Bodenpartien, sondern auch für die Abdeckung von Wandpartien benützt werden. In diesem Fall ist der Deckel gegebenfalls noch zusätzlich gegen das Herausfallen zu sichern.In the figures, the bearing body is only shown as a frame for reasons of space. However, the cover 1 can also be part of a cover in which the bearing body 2 serves to cover a larger area. Such a cover can be used not only for floor parts, but also for covering wall parts. In this case, the cover must be additionally secured against falling out.
