Description

Die Erfindung betrifft eine Entwässerungsrinne mit einem zwei längslaufende, vermittels einer Rinnensohle miteinander verbundene Rinnenwandungen aufweisenden Rinnenkörper, sowie mit einer Zarge zur Auflagerung einer den Rinnenkörper übergreifenden Rinnenabdeckung, wobei die Zarge entlang einer Oberkante eine Umkantung ausbildet, an welche sich eine Innenwange und eine von dieser im Wesentlichen senkrecht abstehende Auflagefläche anschließen, wobei der Zarge unterhalb der Auflagefläche ein U-förmiges, die Auflagefläche untergreifendes Stützprofil angeformt ist, dessen erste U-Flanke mit der Auflagefläche verbunden ist und dessen zweite U-Flanke an der Rinnenwandung anliegt.The invention relates to a drainage channel with a channel body which has two longitudinally running channel walls which are connected to one another by means of a channel sole, and with a frame for supporting a channel cover which overlaps the channel body, the frame forming an edge along an upper edge, to which an inner cheek and one of the latter are formed Connect essentially vertically protruding support surface, the frame being formed below the support surface into a U-shaped support profile which engages under the support surface, the first U-flank of which is connected to the support surface and the second U-flank of which rests on the channel wall.

Eine solche Entwässerungsrinne ist aus der US 2014/0110007 A1 oder auch aus der DE 94 00 242 U1 vorbekannt. Beide Patentschriften zeigen einen Rinnenkörper mit Rinnensohle und zwei Rinnenwandungen, an deren oberem Ende eine Zarge zur Auflage einer Rinnenabdeckung angebracht ist, und bei der der Rinnenkörper mit der Zarge untrennbar verbunden ist, wobei jedoch keine Stoffgleichheit zwischen den beiden Elementen besteht. Die in diesen Schriften beschriebene Verbindung zwischen Zarge und Rinnenkörper stellt damit aber einen aufwändigen zusätzlichen Arbeitsschritt dar. Zudem ergibt sich in beiden Schutzrechten eine massive und schwere Rinnenform, was die beschriebene Einbettung der Zarge in dem Rinnenkörper erst ermöglicht.Such a drainage channel is from the US 2014/0110007 A1 or also from the DE 94 00 242 U1 previously known. Both patents show a gutter body with gutter sole and two gutter walls, at the upper end of which a frame is attached to support a gutter cover, and in which the gutter body is inseparably connected to the frame, but there is no material match between the two elements. However, the connection between the frame and the channel body described in these documents represents a complex additional work step. In addition, both protective rights result in a massive and heavy channel shape, which enables the described embedding of the frame in the channel body.

Weiterer Stand der Technik ist aus der DE 195 11 206 A1 vorbekannt. Dabei wird die Zarge als oberes Rinnenteil derart ausgebildet, dass Zargenseitenwände an den Seitenwänden des Rinnenkörpers entlanggleiten. Zur Gewährleistung einer Höhenverstellbarkeit der Zarge sind innerhalb des Rinnenkörpers in den Randbereichen und sich gegen den Boden des Rinnenkörpers abstützende Doppelrohrführungs-Verstellelemente angeordnet. Die Verstellelemente sind oben, d. h. durch Bohrungen der Zarge und/oder eines Aufsatzrahmens, mittels Schraubgewinde höhenverstellbar. Ein von dieser Zarge aufgenommener und seitlich fixierter Abdeckrost nimmt Belastungskräfte auf und leitet diese über mehrere Verstellelemente auf den durchgehenden Boden des Rinnenkörpers. Der Grundgedanke der vorbekannten Entwässerungsrinne besteht darin, dass im unteren Bereich eine geschlossene Bodengruppe, die letztlich den Rinnenkörper ausbildet, vorgesehen ist. Auf diese Bodengruppe wird mittels teleskopartiger Verstellelemente eine höhenverstellbare Zarge aufgesetzt.Another state of the art is from DE 195 11 206 A1 previously known. The frame is designed as an upper channel part in such a way that frame side walls slide along the side walls of the channel body. To ensure that the frame can be adjusted in height, double pipe guide adjustment elements are arranged within the channel body in the edge regions and against the bottom of the channel body. The adjustment elements can be adjusted in height at the top, ie through holes in the frame and / or an extension frame, using a screw thread. A cover grille, which is held by this frame and fixed on the side, absorbs load forces and guides them to the continuous bottom of the channel body via several adjustment elements. The basic idea of the previously known drainage channel is that a closed bottom group, which ultimately forms the channel body, is provided in the lower region. A height-adjustable frame is placed on this floor assembly using telescopic adjustment elements.

Zusätzlich ist aus der EP 2 851 477 A1 eine Entwässerungsrinne mit einem im Querschnitt etwa U- oder kastenförmigen Rinnenkörper aus Metallblech zur Einbettung in ein Fundament sowie einem die offene Längsseite des Rinnenkörpers abdeckenden Rost vorbekannt. Dieses Dokument stellt den nächstkommenden Stand der Technik dar und offenbart die Merkmale des Oberbegriffs des Anspruchs 1. Bei dieser Entwässerungsrinne sind die Zargen und der eigentliche Rinnenkörper aus einem Bechzuschnitt einstückig ausgebildet und durch Umkanten geformt, wobei unterhalb der Auflagefläche für die Rinnenabdeckung aussenseitig jeweils ein L-förmiges Stützprofil angeformt ist, dessen erster Schenkel mit der Auflagefläche verbunden ist und dessen zweiter Schenkel an der Rinnenwandung anliegt, so dass sich das L-förmige Stützprofil jeweils mit dem von der Auflagefläche entfernt liegenden, zweiten Schenkel an der Rinnenwandung abstüzt.In addition, from the EP 2 851 477 A1 previously known a drainage channel with a cross-sectionally U-shaped or box-shaped channel body made of sheet metal for embedding in a foundation and a grate covering the open long side of the channel body. This document represents the closest prior art and discloses the features of the preamble of claim 1. In this drainage channel, the frames and the actual channel body are made in one piece from a cut to size and are formed by folding, an L being on the outside below the contact surface for the channel cover -shaped support profile is formed, the first leg of which is connected to the support surface and the second leg of which rests on the channel wall, so that the L-shaped support profile is supported on the channel wall with the second leg located at a distance from the support surface.

Der Rinnenkörper wird mittels entlang seiner Längserstreckung seitlich angeordneter Stützkörper zur Übertragung vertikal auf den Rost wirkender Druckkräfte auf ein unterhalb der Stützkörper angeordnetes Fundament in seiner Belastbarkeit verstärkt. Im Übrigen kann der Rinnenkörper mittels zwischen den Seitenwänden des Rinnenkörpers quer zur Längserstreckung des Rinnenkörpers angeordneter Querstege zusätzlich versteift werden. Die Querstege werden mit an den Seitenwänden des Rinnenkörpers vorgesehenen Ausnehmungen verrastet oder im Bereich der Ausnehmungen eingehängt.The channel body is strengthened by means of support bodies arranged laterally along its longitudinal extent for the transmission of pressure forces acting vertically on the grate to a foundation arranged below the support bodies. In addition, the channel body can be additionally stiffened by means of transverse webs arranged between the side walls of the channel body transversely to the longitudinal extent of the channel body. The crossbars are latched with recesses provided on the side walls of the channel body or hung in the region of the recesses.

Eine vergleichbare Aussteifung des Rinnenkörpers durch quer zur Längserstreckung der Rinne einsetzbare Knebelkörper ist auch aus der DE 10 2007 010 073 A1 vorbekannt.A comparable stiffening of the channel body by toggle bodies that can be used transversely to the longitudinal extent of the channel is also from the DE 10 2007 010 073 A1 previously known.

Weiterer relevanter Stand der Technik ergibt sich aus der DE 298 08 197 U1 , der US 2004/0240941 A1 , der DE 202 00 509 U1 und der DE 198 56 689 A1 .Another relevant state of the art results from the DE 298 08 197 U1 , of the US 2004/0240941 A1 , of the DE 202 00 509 U1 and the DE 198 56 689 A1 .

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zu Grunde, durch zusätzliche Merkmale eine weitere Versteifung des Rinnenkörpers, aber auch der dem Rinnenkörper zugehörigen Zarge, rein konstruktiv zu bewirken, um durch die höhere Belastbarkeit einen erweiterten Anwendungsbereich und eine verlängerte Lebensdauer für die erfindungsgemäße Entwässerungsrinne zu erreichen, hierbei jedoch eine leichte und einfache Bauweise der Rinne zu realisieren.Proceeding from this prior art, the object of the invention is to provide a further reinforcement of the channel body, but also of the frame associated with the channel body, by additional features in a purely constructive manner, in order to be able to cope with an extended area of application and a longer service life due to the higher load capacity To achieve drainage channel according to the invention, but to realize a light and simple construction of the channel.

Dies gelingt dadurch, dass als Stützprofil ein U-förmiges Stützprofil verwendet wird, welches die Auflagefläche mit einer ersten U-Flanke unterstützt, indem sich das U-förmige Stützprofil mit seiner von der Auflagefläche entfernt liegenden, zweiten U-Flanke an der Rinnenwandung abstützt. So erfolgt eine Ableitung von Gewichtskräften der Rinnenabdeckung in die Rinnenwandung. Gleichzeitig gewinnt die Auflagefläche und die Gesamtkonstruktion im Vergleich zum Stand der Technik trotz geringen Materialeinsatzes an Formstabilität.This is achieved in that a U-shaped support profile is used as the support profile, which supports the support surface with a first U-flank by the U-shaped support profile being supported on the channel wall with its second U-flank, which is remote from the support surface. In this way, the weight of the channel cover is derived into the channel wall. At the same time, the contact surface and the overall construction gain in shape stability compared to the prior art, despite the low use of materials.

Dabei wird die Entwässerungsrinne als einstückige Kombination aus Zarge und Rinnenkörper hergestellt, indem die beschriebenen Umkantungen direkt mit dem Material des Rinnenkörpers vollzogen werden.The drainage channel is manufactured as a one-piece combination of a frame and channel body, in that the folds described are carried out directly with the material of the channel body.

Die Erfindung wird anhand eines in der Zeichnung nur beispielhaft dargestellten Ausführungsbeispiels näher erläutert. Es zeigen:

Figur 1
eine Entwässerungsrinne mit einer direkt angeformten Zarge in einer perspektivischen Darstellung von schräg oben,
Figur 2
einen Teilquerschnitt der Entwässerungsrinne gemäß Figur 1.
The invention is explained in more detail with reference to an exemplary embodiment shown in the drawing only by way of example. Show it:
Figure 1
a drainage channel with a directly molded frame in a perspective view obliquely from above,
Figure 2
a partial cross section according to the drainage channel Figure 1 .

Figur 1 zeigt eine erste Ausgestaltung einer Entwässerungsrinne 1, welche durch Umkantungen eines einzelnen Blechzuschnitts einstückig gebildet ist. Die Entwässerungsrinne 1 umfasst zunächst einen kastenförmigen Rinnenkörper 2 mit einer Rinnensohle 4, die beidseits von den Rinnenkörper 2 seitlich einfassenden Rinnenwandungen 3, 3' begrenzt ist. Dem Rinnenkörper 2 sind jeweils am oberen Ende der Rinnenwandungen 3, 3' Zargen 5, 5' direkt angeformt, indem die freien Kanten der Rinnenwandungen 3, 3' weiter zu einer Zargenkonstruktion umgebogen wurden. Figure 1 shows a first embodiment of a drainage channel 1, which is formed in one piece by folding a single sheet blank. The drainage channel 1 initially comprises a box-shaped channel body 2 with a channel base 4 which is delimited on both sides by channel walls 3, 3 'which laterally surround the channel body 2. The channel body 2 is formed directly on the upper end of the channel walls 3, 3 'frames 5, 5' by further bending the free edges of the channel walls 3, 3 'into a frame structure.

In der Figur 2 ist zunächst klein ein Querschnitt der Entwässerungsrinne 1 gemäß Figur 1 dargestellt. In diesem ist ein Ausschnitt markiert, der dem Wesentlichen Teil der Figur 2 entspricht, der daneben abgebildet ist. Von einer Rinnensohle 4 her kommend beginnt nach einer rechtwinkligen Abkantung die Rinnenwandung 3, die wiederum nach einer 180°-Umkantung 6 an der hierdurch gebildeten Oberkante der Entwässerungsrinne 1 in eine Innenwange 8 übergeht, die bei eingelegter Rinnenabdeckung diese seitlich kontaktieren würde. Von dieser Innenwange 8 steht um die Dicke einer hier nicht weiter beschriebenen Rinnenabdeckung gegenüber der Oberkante nach unten versetzt eine Auflagefläche 7 ab, unter der sich ein Stützprofil 11 zunächst mit einer ersten U-Flanke 10 anschließt. Eine zweite U-Flanke 12 des Stützprofils 11 kontaktiert die Rinnenwandung 3 und leitet die auf die Rinnenabdeckung wirkenden Gewichtskräfte in diese ein.In the Figure 2 is first a small cross section of the drainage channel 1 according to Figure 1 shown. In this a section is marked, which is the essential part of the Figure 2 corresponds to that shown next to it. Coming from a channel bottom 4, after a right-angled bend, the channel wall 3 begins, which in turn merges after a 180 ° bend 6 on the upper edge of the drainage channel 1 formed in this way into an inner cheek 8 which would contact it laterally if the channel cover was inserted. From this inner cheek 8 there is a support surface 7, offset by the thickness of a channel cover (not described further here) with respect to the upper edge, under which a support profile 11 initially connects with a first U-flank 10. A second U-flank 12 of the support profile 11 contacts the channel wall 3 and introduces the weight forces acting on the channel cover into it.

Vorstehend ist somit eine Entwässerungsrinne beschrieben, die aus einem Rinnenkörper und einer Zarge einstückig durch Umkanten und Biegen in einfacher Weise herstellbar ist, wobei durch das Zusammenspiel und die konstruktive Ausgestaltung der vorstehend bezeichneten Einzelteile insgesamt eine stabilere und belastbare Entwässerungsrinne erzeugt wird, sodass diese beispielsweise als vergleichsweise dünnwandige Blechzuschnitte hergestellt werden können, ohne dass hierunter die Belastbarkeit der Entwässerungsrinne leiden würde.A drainage channel is thus described above, which can be produced in one piece from a channel body and a frame by edging and bending, whereby the interaction and the structural design of the individual parts described above produce a more stable and resilient drainage channel, so that this can be used, for example, as comparatively thin-walled sheet metal blanks can be produced without this affecting the resilience of the drainage channel.
