Grundsätzlich werden derartige Entwässerungsrinnen wahlweise aus Beton, Stahl, Kunststoff, Faserbeton oder Polyesterbeton hergestellt und zur Entwässerung von Straßen, Plätzen, Lagerflächen oder Verkehrsflächen eingesetzt. Zumeist weisen derartige Entwässerungsrinnen Nut- und Federsysteme auf, die beim Verlegen ineinandergreifen und vor allem als Einbauhilfe der Rinnen dienen. Eine automatische Abdichtung ist mit diesen Verbindungen in aller Regel nicht hergestellt. Will man für eine effiziente Abdichtung der Rinnen im Stoßbereich sorgen, so sind gesonderte Dichtungsmaßnahmen erforderlich. Hierbei werden, wie vorstehend erläutert, entweder nachträglich Dichtungsmassen in vorbereitete Nuten eingebracht oder zusätzliche Anschlusselemente als Dichtungsmuffen eingesetzt.Basically, such drainage channels are optionally made of concrete, steel, plastic, fiber concrete or polyester concrete and used for drainage of roads, squares, storage areas or traffic areas. In most cases, such drainage channels on tongue and groove systems, which mesh when laying and above all serve as installation aid of the gutters. An automatic seal is not made with these compounds in most cases. If you want to ensure an efficient sealing of the gutters in the joint area, so special sealing measures are required. Here, as explained above, either subsequently introduced sealing compounds in prepared grooves or additional connection elements used as sealing sleeves.
Alle genannten nachträglichen oder zusätzlichen Baumaßnahmen sind jeweils mit zusätzlichen Kosten verbunden und werden daher nur in Ausnahmefällen oder zumindest selten verbaut. Dies liegt nicht zuletzt daran, dass die gängigen DIN-Normen sowie die europäische Norm EN 1433, betreffend Entwässerungsrinnen für Verkehrsflächen regelmäßig eine Dichtigkeitsprüfung für die eingesetzten Rinnenkörper als solche verlangt aber keine Vorschriften bezüglich der Verbindung zwischen den einzelnen Rinnenabschnitten vorsieht.All mentioned subsequent or additional construction measures are associated with additional costs and are therefore only in exceptional cases or at least rarely installed. This is due not least to the fact that the current DIN standards and the European standard EN 1433, concerning drainage channels for traffic areas regularly a leak test for the used But channel body as such requires no rules regarding the connection between the individual channel sections provides.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zu Grunde, die Stoßverbindung zwischen den an dieser Verbindung beteiligten Rinnenkörpern so zu gestalten, dass direkt beim Verlegen der Rinnenkörper selbsttätig, d.h. ohne zusätzlichen nachträglichen Dichtungsaufwand oder nachträglich anzubringende Elemente, eine dichte Stoßverbindung und zwar über den gesamten Umfang der stirnseitigen Verbindung der beteiligten Rinnenkörper hergestellt ist.Based on this prior art, the invention is based on the object to make the butt joint between the channel bodies involved in this connection so that directly when laying the gutter body automatically, i. without additional subsequent sealing effort or subsequently to be attached elements, a tight butt joint and that is made over the entire circumference of the frontal connection of the gutter body involved.
Die Lösung dieser Aufgabe gelingt mittels einer Entwässerungsrinne umfassend zwei in der Einbaulage einander benachbart angeordnete, jeweils einteilige Rinnenkörper mit den Merkmalen des geltenden Anspruchs 1. Vorteilhafte Ausgestaltungen und Weiterbildungen dieser Erfindung können den abhängigen Ansprüchen 2 bis 6 entnommen werden.The solution of this object is achieved by means of a drainage channel comprising two adjacently disposed in the installation position, each one-piece channel body with the features of the
Zusätzlich zu der vorbekannten Nut-Feder-Verbindung, die üblicherweise lediglich eine Auszugssicherung der Stoßverbindung in Richtung der sich längs erstreckenden Rinnenkörper bewirkt, sieht die erfindungsgemäße Lösung ein Zusammenwirken eines zusätzlichen Rastelementes auf der Federseite mit einem zusätzlichen komplementären Halteelement auf der Nutseite vor, derart, dass hierdurch eine Sicherung der Nut-Feder-Verbindung auch vertikal zur Längserstreckung der verbundenen Rinnenkörper bewirkt wird und diese somit gegen eine Verschiebung nach oben oder unten gegeneinander in Verbindung mit einer Aufhebung der durch die Verbindung bewirkten Dichtung verhindert ist. Außerdem sorgt ein drittes Arretierungselement bei der erfindungsgemäßen Lösung dafür, dass auch die Verbindung quer zur Längserstreckung der beiden Rinnenkörper gesichert ist und diese somit auch in dieser Richtung aneinander gepresst werden, so dass die Dichtung in allen drei Achsen ihrer räumlichen Erstreckung gesichert und derart angepresst ist, dass eine verdichte Verbindung zwischen den beteiligten Rinnenkörpern hergestellt ist.In addition to the previously known tongue and groove connection, which usually only causes a pull-out protection of the butt joint in the direction of the longitudinally extending channel body, the solution according to the invention provides for an interaction of an additional locking element on the spring side with an additional complementary retaining element on the groove side, in such a way that thereby securing the tongue and groove connection is also effected vertically to the longitudinal extent of the connected channel body and this is thus prevented against displacement upwards or downwards against each other in conjunction with a cancellation of the seal caused by the connection. In addition, a third locking element in the solution according to the invention ensures that the connection is secured transversely to the longitudinal extent of the two channel body and thus they are pressed together in this direction, so that the seal is secured in all three axes of their spatial extent and pressed in such a way in that a sealed connection is established between the gutters involved.
Dabei ist es für den Gegenstand der Erfindung unerheblich, ob das Rastelement auf der Feder- oder der Nutseite bzw. das komplementäre Halteelement auf der Nut- bzw. Federseite der Stoßverbindung angeordnet sind. Sämtliche genannten Ausführungen sind als Bestandteil der Erfindung sowie als gleichwirkend anzusehen.It is irrelevant for the object of the invention, whether the locking element on the spring or the groove side or the complementary retaining element on the tongue or spring side of the butt joint are arranged. All mentioned embodiments are to be regarded as part of the invention as well as the same effect.
Außerdem kann die Dichtheit der erfindungsgemäßen Nut-Feder-Verbindung dadurch noch weiter verbessert werden, dass die Verbindung der beteiligten Entwässerungsrinnen unter Zwischenlage eines Dichtungsprofils hergestellt wird.In addition, the tightness of the tongue and groove connection according to the invention can be further improved by the fact that the connection of the participating drainage channels is made with the interposition of a sealing profile.
In dieser Verbindung greift das Rastelement auf der Nut- oder Federseite der Stoßverbindung zur Ausbildung der Stoßverbindung in eine korrespondierende Ausnehmung auf der Feder- oder Nutseite des jeweils anderen Rinnenkörpers ein, so dass hierdurch eine Sicherung der Verbindung in vertikaler Richtung zur Längserstreckung der beteiligten Rinnenkörper hergestellt ist.In this connection, the latching element engages on the tongue or spring side of the butt joint to form the butt joint in a corresponding recess on the spring or groove side of the respective other channel body, thereby producing a backup of the compound in the vertical direction to the longitudinal extent of the involved gutter body is.
In zusätzlicher oder alternativer Ausgestaltung können auf der Nut- oder Federseite ein oder mehrere Sägezahnflächen auf der Außen- bzw. Innenseite der Nut- bzw. der Federseite des einen Rinnenkörpers angeformt sein und gleichzeitig auf der Feder- oder Nutseite des jeweils anderen Rinnenkörpers korrespondierende, jeweils komplementäre weitere Sägezahnflächen zur Ausbildung einer Rastverbindung im Stoßbereich der beteiligten Rinnenkörper und hierdurch eine Sicherung der Stoßverbindung vertikal zur Längserstreckung der verbundenen Rinnenkörper hergestellt sein.In an additional or alternative embodiment, one or more sawtooth surfaces on the outside or inside of the groove or the spring side of a channel body can be integrally formed on the tongue or tongue side and at the same time on the spring or groove side of the respective other channel body corresponding, respectively complementary further sawtooth surfaces for forming a latching connection in the joint area of the involved gutter body and thereby securing the butt joint to be made vertically to the longitudinal extent of the connected gutter body.
In bevorzugter Ausführung kann als Dichtung bzw. als zwischen den Rinnenkörpern eingelegtes Dichtungselement eine Moosgummi- oder moosgummiähnliche Profildichtung eingesetzt werden.In a preferred embodiment can be used as a seal or as between the channel bodies inserted sealing element a foam rubber or moss rubber-like profile seal.
In besonders vorteilhafter Ausgestaltung kann die erfindungsgemäße Lösung in Verbindung mit Kunststoffrinnen eingesetzt werden, die in einem Spritzgussverfahren hergestellt werden. Dabei können die erfindungsgemäßen Verbindungselemente zu der ohnehin bestehenden Nut-Feder-Verbindung, also das zusätzliche Rastelement und das hierzu komplementäre Halteelement und/oder auch das weitere Arretierungselement direkt bei der Herstellung der Rinnenkörper bei dem in diesem Zusammenhang eingesetzten Werkzeug berücksichtigt werden, dass durch die zusätzlichen Verbindungselemente keine oder so gut wie keine zusätzlichen Produktionskosten verursacht sind. Allenfalls muss zusätzlich die vorstehend erwähnte Profildichtung noch nachträglich eingearbeitet werden, was allerdings auch im Rahmen eines automatisierten Fertigungsschrittes sehr kostengünstig realisierbar ist.In a particularly advantageous embodiment, the solution according to the invention can be used in conjunction with plastic troughs, which are produced in an injection molding process. In this case, the connecting elements according to the invention to the already existing tongue and groove connection, so the additional locking element and complementary thereto holding element and / or the further locking element directly in the manufacture of the channel body in the tool used in this context can be considered that through the additional fasteners are no or almost no additional production costs caused. At most, in addition, the above-mentioned profile seal must be incorporated later, but this can also be realized very inexpensively in the context of an automated manufacturing step.
Dabei kann die erfindungsgemäße Lösung selbstverständlich auch in Verbindung mit Rinnenkörpern realisiert werden, die aus nicht nachgebenden Werkstoffen, insbesondere aus Beton oder Polyesterbeton hergestellt sind, wobei in diesem Falle die zusätzlichen Verbindungselemente mittels im Nut- und/oder Federbereich zusätzlich innen- und/oder außenseitig aufgebrachter Kunststoffinlays kostengünstig realisierbar sind.In this case, the solution according to the invention can of course also be realized in conjunction with gutter bodies, which are made of non-yielding materials, in particular concrete or polyester concrete, in which case the additional connecting elements by means in the groove and / or spring area additionally inside and / or outside applied plastic inlays are inexpensive to implement.

Dabei ist der Federsteg 4 mit einer umlaufenden vorspringenden Kante 5 versehen, die beim Zusammenfügen der beiden Rinnenkörper 1 und 2 in eine korrespondierende umlaufende Nut 6 des Nutstegs 3 eingreift. Bei geschlossener Nut-Feder-Verbindung ist eine Auszugssicherung der Stoßverbindung in Längsrichtung der beiden miteinander verbundenen Rinnenkörper 1, 2 bewirkt. Zusätzlich sind an den Federsteg 4 am Außenumfang über den Außenumfang zwei vorspringende Rastelemente 7 angeformt, die mit zwei mit den Rastelementen 7 korrespondierenden Ausnehmungen 8 des Nutstegs 3 derart in Eingriff bringbar sind, dass eine zusätzliche Sicherung der Stoßverbindung der beiden beteiligten Rinnenkörper 1, 2 vertikal zur Längserstreckung der beiden Rinnenkörper 1, 2 bewirkt ist.In this case, the
Im Übrigen ist im Bereich der Zarge stirnseitig auf beiden Seiten beabstandet von dem Außenumfang des Federstegs 4 je ein Haltezapfen 10 angeformt. Bei geschlossener Stoßverbindung übergreift der Haltezapfen 10 auf beiden Seiten den Außenumfang des Nutstegs 3 und presst diesen somit an den innenliegenden Federsteg 4 an und stellt somit überdies eine Sicherung der Verbindung quer zur Längserstreckung der beteiligten Rinnenkörper 1 und 2 sicher.Incidentally, in the region of the frame, a retaining

In der Verbindungslage der beiden Rinnenkörper 1, 2 übergreift erneut beidseitig jeweils ein Haltezapfen 10 die Oberkante des den Federsteg 4 umgreifenden Nutstegs 3 und drückt diesen in der Verbindungslage an den innenliegenden Federsteg 4.In the connecting position of the two
Zusätzlich sind an der Außenseite des Federstegs 4 zwei mit einer entsprechenden Profilierung versehene, Sägezahnelemente 11, das mit zwei korrespondierenden weiteren Sägezahnelementen 12 des Nutstegs 3 derart zusammenwirkt, dass die korrespondierenden Profilierungen der Sägezahnelemente 11 und 12 derart ineinander geschoben werden, dass bei geschlossener Verbindung eine Lösung der Verbindung vertikal zur Längserstreckung der beteiligten Rinnenkörper 1 und 2 wirksam verhindert ist. Durch das Zusammenwirken der beiden Sägezahnelemente 11 und 12 wird darüber hinaus in vertikaler Richtung ein zusätzlicher Anpressdruck zwischen den beteiligten Rinnenkörpern 1 und 2 hergestellt, der für eine weitere Abdichtung der Stoßverbindung zwischen den beiden Rinnenkörpern 1 und 2 sorgt.In addition, on the outside of the

Darüber hinaus ist die geschlossene Stoßverbindung gemäß
Vorstehend ist somit die Ausbildung einer Stoßverbindung zwischen zwei im wesentlichen baugleichen Rinnenkörpern beschrieben, die im Unterschied zum Stand der Technik in wenigstens zwei, vorzugsweise drei denkbare einander orthogonale Bewegungsrichtungen gesichert ist und durch den hierdurch bewirkten Anpressdruck und/oder aber eine zusätzliche Abdichtung weitgehend oder vollständig abgedichtet ist, wobei zumindest im Falle der Herstellung der Rinnenkörper im Spritzguss die zusätzlichen Arretierungselemente innerhalb des Spritzgusswerkzeugs berücksichtigt werden können, so dass die verbesserte Abdichtung ohne zusätzliche Dichtungsmaßnahmen und weitgehend ohne zusätzliche Produktionskosten bewirkt werden kann. Auch im Falle von Betonrinnen kann durch entsprechende Kunststoffinlays in einfacher Weise die vorstehend erläuterte verbesserte Abdichtung erreicht werden.The above thus described the formation of a butt joint between two substantially identical channel bodies, which in contrast to the prior art in at least two, preferably three conceivable orthogonal directions of movement is secured and largely or completely by the contact pressure caused thereby and / or an additional seal is sealed, wherein at least in the case of production of the gutter body in the injection molding, the additional locking elements can be considered within the injection mold, so that the improved seal can be effected without additional sealing measures and largely without additional production costs. Even in the case of concrete gutters can be achieved by appropriate Kunststoffinlays in a simple manner, the above-described improved sealing.

Claims (6)
- A drainage channel, comprising two channel bodies (1, 2) which are arranged adjacent to each other in the installation position and which are connected to each other by forming a sealing system for sealing the abutment region between said channel bodies (2, 3), wherein the face end of the one channel body (1) is formed as a groove side and the face end of the other channel body (2) is formed as a tongue side, and said channel bodies (1) are connected to each other in the abutment region by a tongue-and-groove connection as the first locking element, and at least one retraction protection means of the abutment connection is thus produced between the two channel bodies (1, 2) in the horizontal direction, i.e. in the direction of the longitudinal extension of the channel bodies (1 2), characterized in that at least one locking element (7) of the other channel body (2) can be connected in a latching manner in addition as a second locking element to at least a respectively corresponding recess (8) of the one channel body (1) on the groove side, and the securing of the tongue-and-groove connection of the two channel bodies (1, 2) in the installation position vertically to the longitudinal extension of the mutually connected channel bodies (1, 2) can thus be produced, wherein the channel bodies (1 2) which are involved in the connection are respectively integrally formed with their locking means (7, 8, 10) and in addition a retaining pin (10), which is respectively integrally attached to both sides of the other channel body (2), engages in the installation position about the outer circumference of the adjacent channel body, and thus produces as the third locking element a securing of the connection transversely to the longitudinal extension of the channel bodies (1, 2) involved in said connection, wherein a pressing pressure can be produced by means of the second and third locking elements (7, 8, 10) vertically to the longitudinal extension and transversely to the longitudinal extension of the channel bodies (1, 2) involved in the connection, and an at least approximately tight connection of the involved channel bodies (1, 2) can thus be produced.
- A drainage channel according to claim 1, characterized in that the tongue-and-groove connection between the two channel bodies (1, 2) is formed by interposing a sealing profile.
- A drainage channel according to one of the preceding claims 1 or 2, characterized in that on the groove or tongue side one or several sawtooth elements (11) are integrally formed on the outer or inner side of the groove or tongue side, and corresponding, respectively complementary, further sawtooth areas (12) are produced on the tongue or groove side of the respective other channel body (2) for forming a latched connection in the abutment region of the involved channel bodies (1, 2), and a securing of the abutment connection vertically to the longitudinal extension of the connected channel bodies (1, 2) is thus produced.
- A drainage channel according to claim 2, characterized in that the sealing profile is formed as a soft profile seal, preferably sponge rubber or sponge-rubber-like.
- A drainage channel according to one or several of the preceding claims, characterized in that the channel bodies (1, 2) are made of plastic, preferably of PP or recyclate, especially by means of an injection-moulding method.
- A drainage channel according to one or several of the preceding claims 1 to 4, characterized in that the channel bodies (1, 2) are made of hard materials, especially concrete or polyester concrete, wherein in the abutment region on the groove and/or tongue side plastic inlays are incorporated on the inside and/or outside with the corresponding connecting elements according to the preceding claims, and the abutment connection of the involved channel bodies (1, 2) is produced by means of said plastic inlays.
