Description

Die Erfindung betrifft ein als Reinigungsverschluß verwendbares Aufsatzstück mit Deckel für Entwässerungsleitungen, mit einem einstückigen Gehäuse, das oben einen rechtekkigen Rahmen und einen von diesem nach unten abgehenden Rohranschlußstutzen sowie am Übergang beider eine nach innen vorspringende Schulter aufweist, die die Abstützfläche für den ebenfalls rechteckigen Deckel bildet, der am Gehause durch einen Dichtring abgedichtet und durch Befestigungsmittel befestigt ist.The invention relates to a usable as a cleaning cap with a cover for drainage pipes, with a one-piece housing that has a rectangular frame at the top and a pipe connection stub coming down from it, and at the transition of both an inwardly projecting shoulder, which has the support surface for the likewise rectangular cover forms, which is sealed to the housing by a sealing ring and fastened by fasteners.

Abwasserleitungen, insbesondere solche, die den Fallstrang in Häusern mit dem Straßenkanal verbinden, müssen mit Reinigungsöffnungen versehen sein, damit im Fall einer Verstopfung die Leitung für Reinigungsvorrichtungen zugänglich wird. Bei in bzw. unter einem Boden verlegten Leitungen sieht man hierfür in der Regel nach oben abgehende Abzweige vor, auf die als Reinigungsverschluß ein Aufsatzstück der eingangs genannten Art aufgesetzt wird, so daß Rahmen und Deckel bündig mit dem Boden liegen. Ein derartiges Aufsatzstück ist aus DE-U-7 533 387 bekannt. Solche Aufsatzstücke bzw. Reinigungsverschlüsse sollen der Forderung genügen, daß sie gegen Rückstauwasser gesichert und abgedichtet sind, quadratischen Rahmens aufweisen, in lotrechter z.B. dem gängigen Fliesenmaß angepaßten Abmessungen des rechteckigen, insbesondere quadratischen Rahmens aufweisen, in lotrechter Richtung geringen Platzbedarf haben, ein einfaches Lösen und Wiedereinsetzen des Deckels gestatten und kostengünstig herstellbar sind.Waste water pipes, especially those that connect the downpipe in houses to the street sewer, must be provided with cleaning openings so that the pipe is accessible to cleaning devices in the event of a blockage. In the case of cables laid in or under a floor, branches are usually provided for this purpose, onto which an attachment piece of the type mentioned at the outset is placed as a cleaning closure, so that the frame and cover lie flush with the floor. Such an attachment piece is known from DE-U-7 533 387. Such attachments or cleaning closures should meet the requirement that they are secured and sealed against backwater, have square frames, in vertical e.g. have the customary dimensions of the rectangular, in particular square, frame, have a small space requirement in the vertical direction, allow easy removal and reinsertion of the cover and are inexpensive to produce.

Bei dem bekannten Reinigungsverschluß nach DE-U-7 533 387 ist der Deckel am Gehäuse dadurch befestigt, daß ein an der glatten Innenwandung des Rohrstutzens des Gehäuses anliegender Radialdichtungsring mittels eines am Deckel vorgesehenen, durch eine Schraube gegen den Deckel verspannbaren Druckrings gegen die Rohrinnenwandung angepreßt wird, um den Deckel am Gehäuse festzuklemmen. Diese Konstruktion ist baulich aufwendig und ergibt nur eine reibschlüssige Sicherung des Deckels am Gehäuse. Für eine sichere Befestigung des Deckels sind sehr hohe Verspannungskräfte nötig, für deren Aufnahme eine ziemlich massive gußeiserne Konstruktion des Gehäuses und des Deckels nötig ist. Außerdem stellt die für die Spannschraube notwendige Durchbrechung eine Stelle dar, an der eine Undichtigkeit auftreten kann. Der bekannte Reinigungsverschluß ist deshalb nicht optimal betriebssicher.In the known cleaning closure according to DE-U-7 533 387, the cover is fastened to the housing by pressing a radial sealing ring against the smooth inner wall of the pipe socket of the housing by means of a pressure ring provided on the cover and clampable by a screw against the cover against the inner wall of the pipe to clamp the cover to the housing. This construction is structurally complex and only results in a frictionally locking securing of the cover to the housing. Very high tensioning forces are required for a secure attachment of the cover, and a fairly massive cast-iron construction of the housing and the cover is necessary for the accommodation thereof. In addition, the opening required for the clamping screw represents a point at which a leak can occur. The known cleaning closure is therefore not optimally reliable.

Aufgabe der Erfindung ist es, ein als Reinigungsverschluß verwendbares Aufsatzstück der genannten Art so zu verbessern, daß es einfach, kostengünstig und in besonders knappen Abmessungen herstellbar ist, gleichwohl aber eine sichere Befestigung und Abdichtung des Deckels am Gehäuse gestattet. Dabei ist zusätzlich die Forderung gestellt, daß die lichte Weite des Rahmens möglichst vollständig für den Querschnitt des abgehenden Rohrstutzens nutzbar sein soll.The object of the invention is to improve a usable as a cleaning cap attachment of the type mentioned so that it is simple, inexpensive and can be produced in particularly tight dimensions, but still allows a secure attachment and sealing of the cover on the housing. There is also the requirement that the clear width of the frame should be used as completely as possible for the cross section of the outgoing pipe socket.

Zur Lösung der Aufgabe ist erfindungsgemäß ein Aufsatzstück der eingangs genannten Art dadurch gekennzeichnet, daß die Schulter an ihrer kreisrund umlaufenden Innenkante eine nach innen abgeschrägte und/oder ausgekehlte Dichtfläche für die Aufnahme und Zentrierung des Dichtrings bildet und daß der Deckel an seiner Unterseite eine entsprechend nach außen abgeschrägter und/oder ausgekehlte Dichtfläche zur zentrierenden Auflage auf dem Dichtring aufweist und außerhalb des Dichtrings mit dem Gehäuse verschraubt ist.To achieve the object, an attachment piece of the type mentioned is characterized in that the shoulder on its circular inner edge forms an inwardly chamfered and / or grooved sealing surface for receiving and centering the sealing ring and that the cover on its underside accordingly has a bevelled and / or grooved sealing surface on the outside for centering support on the sealing ring and is screwed to the housing outside the sealing ring.

Hierdurch wird eine formschlüssige Verbindung des Deckels mit dem Gehäuse geschaffen und die von der Befestigung unabhängige Abdichtung derart platzsparend angeordnet, daß sie in lotrechter und radialer Richtung nur wenig Platz benötigt. Die Verschraubungen liegen jetzt außerhalb des abgedichteten Querschnitts, können also die Funktion bei Rückstau nicht beeinträchtigen.This creates a positive connection of the cover to the housing and the sealing, which is independent of the fastening, is arranged in a space-saving manner in such a way that it requires little space in the vertical and radial directions. The screw connections are now outside of the sealed cross-section, so they cannot impair the function in the case of backflow.

Eine besonders platzparende Konstruktion erreicht man, wenn die Dichtfläche des Gehäuses an den Seitenmitten des Rahmens tangential in dessen Innenwände übergeht, wobei lediglich die in den Ecken des Rahmens verbleibenden Zwickel der Schulter Abstützflächen für den Deckel bilden.A particularly space-saving design is achieved if the sealing surface of the housing merges tangentially into the inner walls of the frame at the side centers, only the gussets of the shoulder remaining in the corners of the frame forming support surfaces for the cover.

Auch erreicht man eine sehr gute Abdichtung bei geringem Platzbedarf, wenn der Dichtring von der Dichtfläche des Gehäuses im wesentlichen auf dem unteren äußeren Viertel und von der Dichtfläche des Deckels im wesentlichen auf dem oberen inneren Viertel des Umfangs seines Querschnitts umfaßt wird.A very good seal can also be achieved with a small space requirement if the sealing ring is encompassed by the sealing surface of the housing essentially on the lower outer quarter and by the sealing surface of the cover essentially on the upper inner quarter of the circumference of its cross section.

Die Höhenlage der Abstützflächen ist auf diejenige der beiden Dichtflächen so abgestimmt, daß bei fest verschraubtem, also tragend aufliegendem Deckel der Dichtring einer ausreichenden Pressung unterliegt, so daß er ohne Überbeanspruchung dem maximal zulässigen Rückstaudruck standhält. Die Anordnung des Dichtringes entspricht somit weder der von bekannten Rollringen, die nur radial gepreßt werden, noch der von Flachdichtungen, die nur axial zusammengedrückt werden. Es ist vielmehr an der Grenze zwischen der Dichtfläche einer Flachdichtung und derjenigen eines Rollrings angeordnet, wodurch die Platzersparnis und die optimale Funktionssicherheit erzielt werden.The height of the support surfaces is matched to that of the two sealing surfaces so that when the cover is screwed tightly, that is to say in a load-bearing manner, the sealing ring is subjected to sufficient pressure so that it withstands the maximum permissible back pressure without overstressing. The arrangement of the sealing ring thus does not correspond to that of known rolling rings, which are only pressed radially, nor that of flat seals, which are only pressed together axially. Rather, it is arranged on the boundary between the sealing surface of a flat gasket and that of a rolling ring, which saves space and ensures optimum functional reliability.

Weitere vorteilhafte Merkmale der Erfindung sind aus den Unteransprüchen 3 und 5-8 ersichtlich.Further advantageous features of the invention can be seen from subclaims 3 and 5-8.

Embodiments of the invention are explained below with reference to the drawings.
  • Fig. 1 shows schematically and with parts cut away the attachment piece with Housing and cover according to an embodiment of the invention;
  • Fig. 2 shows the same embodiment in section along the line 11-11 of Fig. 3;

Gemäß Fig. 1 bis 4 besteht das Aufsatzstück aus einem Gehäuse 1 und einem Deckel 2. Das Gehäuse 1 bildet oben einen quadratischen Rahmen 3 mit lotrechten Innenwänden 4 und geht über eine Schulter 5, der an der Außenseite ein Rücksprung entspricht, in einen Rohrstutzen 6 über, der z.B. an das (nicht dargestellte) Muffenende eines lotrechten Leitungsrohres angeschlossen werden kann. Der Rahmen 3 hat an seiner Außenseite vorzugsweise die Abmessungen üblicher Bodenfliesen, so daß er flächenbündig mit einem Fliesenbelag verlegt werden kann. Bei gleichbleibenden Rahmenabmessungen kann das Gehäuse 1 mit unterschiedlichen Durchmessern des Rohrstutzens 6 hergestellt werden, wie in Fig. 2 bis 6', 6" angedeutet.1 to 4, the top piece consists of a housing 1 and a cover 2. The housing 1 forms a square frame 3 with vertical inner walls 4 at the top and goes over a shoulder 5, which corresponds to a recess on the outside, into a pipe socket 6 about who eg can be connected to the (not shown) sleeve end of a vertical conduit. The frame 3 preferably has the dimensions of conventional floor tiles on its outside so that it can be laid flush with a tile covering. With the frame dimensions remaining the same, the housing 1 can be produced with different diameters of the pipe socket 6, as indicated in FIGS. 2 to 6 ′, 6 ″.

Der innere kreisrunde Rand der Schulter 5 ist viertelkreisförmig ausgekehlt und bildet eine Dichtfläche 7, die einen Dichtring 8 von rundem oder elliptischem Querschnitt aufnimmt und zentriert, und an diesem im wesentlichen entlang des unteren äußeren Viertels seines Querschnittumfangs anliegt. Die Auskehlung 7 verläuft derart, daß sie an den Seitenmitten des Rahmens 3 tangential unmittelbar in die lotrechten Wände 4 übergeht. In den verbleibenden Zwickeln in den Ecken des Rahmens 3 bildet die Schulter 5 waagrechte Abstützflächen für den Deckel 2, wobei vorzugsweise etwas erhöhte Paßflächen 9 in den Rahmenecken für die Abstützung des Deckels 2 vorgesehen sind. Der so an allen vier Ecken abgestützte Deckel 2 hat am Rand einen nach unten gerichteten, kreisrund umlaufenden Steg 10, an dessen Unterseite eine nach außen viertelkreisförmig ausgekehlte Dichtfläche 11 vorgesehen ist, die mit dem Dichtring 8 zusammenwirkt. Diese Dichtfläche 11 liegt am Dichtring 8 im wesentlichen auf dem oberen inneren Viertel seines Querschnittumfangs an und zentriert ihn von innen.The inner circular edge of the shoulder 5 is chamfered in a quarter circle and forms a sealing surface 7, which receives and centers a sealing ring 8 of round or elliptical cross section, and bears against this essentially along the lower outer quarter of its cross-sectional circumference. The groove 7 runs in such a way that it merges tangentially directly into the vertical walls 4 at the side centers of the frame 3. In the remaining gussets in the corners of the frame 3, the shoulder 5 forms horizontal support surfaces for the cover 2, preferably slightly increased fitting surfaces 9 being provided in the frame corners for supporting the cover 2. The lid 2, supported in this way at all four corners, has a downwardly directed, circular web 10 on the underside, on the underside of which there is provided a sealing surface 11 which is fluted outward in a quarter circle and which cooperates with the sealing ring 8. This sealing surface 11 lies on the sealing ring 8 essentially on the upper inner quarter of its cross-sectional circumference and centers it from the inside.

In zwei einander diagonal gegenüberliegenden Ecken ist der Deckel 2 am Gehäuse 1 mittels Schrauben 12 verschraubt, die in Gewindebohrungen der Schulter 5 eingeschraubt sind. Jede Schraube 12 ist am Deckel 2 durch einen auf den Schraubenschaft angebrachten Bund 13 gesichert, der in einer unteren Ausnehmung 14 des Deckels 2 so viel Spiel in Längsrichtung der Schraube 12 hat, daß die Schraube 12 ganz aus der Gewindebohrung herausgeschraubt werden kann, bevor der Bund 13 am Boden der Vertiefung 14 anschlägt. An den dann über die Oberseite des Deckels 2 hinausstehenden Köpfen der Schrauben 12 kann dann ein Aushebewerkzeug angesetzt werden, um den Deckel 2 aus dem Rahmen 3 herauszuheben.In two diagonally opposite corners, the cover 2 is screwed to the housing 1 by means of screws 12 which are screwed into threaded holes in the shoulder 5. Each screw 12 is secured to the cover 2 by a collar 13 attached to the screw shaft, which has so much play in the longitudinal direction of the screw 12 in a lower recess 14 of the cover 2 that the screw 12 can be completely unscrewed from the threaded bore before the Collar 13 strikes the bottom of the recess 14. A lifting tool can then be attached to the heads of the screws 12 which then protrude above the top of the cover 2 in order to lift the cover 2 out of the frame 3.

Die dargestellte Abdichtung des Deckels 2 mittels des Dichtrings 8, der sowohl axial als auch radial zusammengedrückt wird, ergibt eine besonders einfache und betriebssichere Abdichtung bei geringstem Platzbedarf und wird ermöglicht dadurch, daß die Abstützflächen 9 für den Deckel 2 getrennt von Dichtbereich vorgesehen sind.The illustrated sealing of the cover 2 by means of the sealing ring 8, which is compressed both axially and radially, results in a particularly simple and reliable sealing with the smallest space requirement and is made possible in that the support surfaces 9 for the cover 2 are provided separately from the sealing area.

Bei der Ausführungsform nach Fig. 1 bis 4 hat der Deckel eine glatte Oberseite und nach unten vorspringende Stege 10. Bei der Ausführungsform nach Fig. 5 hat der Deckel 2 einen nach oben ragenden Kragen 15, der einen muldenförmigen Hohlraum umschließt. Dieser Hohlraum kann mit einer Füllmasse, z.B. Beton oder einem dekorativen Kunststeinmaterial ausgefüllt werden, um den Deckel 2 an den ihn umgebenden Bodenbelag anzupassen. An zwei diametral gegenüberliegenden Ecken hat der Kragen 15 verstärke Eckklötze 16 zur Unterbringung der Befestigungsschrauben 12.,In the embodiment according to FIGS. 1 to 4, the cover has a smooth upper side and webs 10 projecting downwards. In the embodiment according to FIG. 5, the cover 2 has an upwardly projecting collar 15 which encloses a trough-shaped cavity. This cavity can be filled with a filling compound, e.g. Concrete or a decorative artificial stone material to be filled to adapt the cover 2 to the surrounding flooring. At two diametrically opposite corners, the collar 15 has reinforced corner blocks 16 for accommodating the fastening screws 12.

Zum Anschluß einer feuchtigkeitsdämmenden Dichtungsbahn kann das Gehäuse auch einen Anschlußflansch 19 gemäß Fig. 2 erhalten. Wenn die Dichtungsbahn nicht geklebt, sondern eingespannt werden soll, kann noch ein Losflansch 20 vorgesehen werden, der mit dem Festflansch 19 verschraubt wird.To connect a moisture-insulating sealing membrane, the housing can also be provided with a connecting flange 19 according to FIG. 2. If the sealing membrane is not to be glued but to be clamped in, a loose flange 20 can also be provided, which is screwed to the fixed flange 19.

Da der Rohrstutzen des Aufsatzstücks die dem Spitzende eines Muffenrohres entsprechenden Abmessungen hat, kann man ihn in ein Ablaufgehäuse mit beliebigem Ablaufstutzen einsetzen, und zwar unter Zwischenfügen eines Rollringes od. dgl. Dadurch entsteht ein Ablauf oder ein Reinigungsverschluß, der stufenlos an unterschiedliche Decken- und Belagdicken angepaßt werden kann.Since the pipe socket of the attachment piece has the dimensions corresponding to the spigot end of a socket pipe, it can be inserted into a drain housing with any drain socket, with the interposition of a roller ring or the like. This creates a drain or a cleaning closure that can be smoothly attached to different ceilings and Base thicknesses can be adjusted.
