Abstract

Webs (107) form run-off slots (109) and are joined together by bridging sections. These bridging sections are arranged off centre and displaced towards first and second contact sections (105,106) so the run-off slots have different lengths, forming alternately arranged long and short slots. Two webs may form three slots, connected by two bridging sections which are arranged symmetrically to the longitudinal central axis of the channel. There are supports (115) on the underside of the webs, having a height greater than the contact section width.

Description

Die Erfindung betrifft einen Abdeckrost für eine Oberflächenentwässerungsrinne nach dem Oberbegriff des Anspruches 1 oder 4.The invention relates to a cover grate for a surface drainage channel according to the preamble of claim 1 or 4.

Bereits aus der DE-B- 1 272 241 ist ein Abdeckrost für eine Oberflächenentwässerungseinrichtung bekannt. Der dort beschriebenen Abdeckrost für eine Oberflächenentwässerungseinrichtung soll ein großes Schluckvermögen aufweisen, dadurch, daß er mit über die Oberfläche hinausragenden Noppen versehen ist. Diese Noppen haben die Wirkung von Pralleisten und vernichten die kinetische Energie des anströmenden Wassers, so daß das Schluckvermögen des Abdeckrostes erhöht wird. Durch diese Maßnahme soll die Entwässerungsleistung bei überfließendem Wasser verbessert werden. Außerdem soll durch die nach oben vorstehenden Noppen die Griffestigkeit des Abdeckrostes erhöht werden.A grating for a surface drainage device is already known from DE-B-1 272 241. The cover grate described there for a surface drainage device is said to have a large swallowing capacity, in that it is provided with knobs protruding beyond the surface. These knobs have the effect of baffle bars and destroy the kinetic energy of the incoming water, so that the swallowing capacity of the grating is increased. This measure is intended to improve the drainage performance in the case of overflowing water. In addition, the grip of the cover grate is to be increased by the knobs protruding upwards.

Der dort beschriebene Abedeckrost enthält die notwendige Stabilität jedoch erst dadurch, daß er vergleichsweise massiv und damit schwer ausgebildet wird. Derartige Abdeckroste, die typischerweise aus Gußeisen bestehen, sind jedoch in der Handhabung, beispielsweise bei der Reinigung der Oberflächenentwässerungseinrichtungen äußerst hinderlich. Gerade bei Entwässerungsrinnen können lange Abdeckroste zu Schwierigkeiten bei der Handhabung führen.However, the covering grate described there only contains the necessary stability in that it is comparatively solid and thus heavy. Cover grilles of this type, which typically consist of cast iron, are extremely difficult to handle, for example when cleaning the surface drainage devices. Especially with drainage channels, long cover grids can lead to difficulties in handling.

Es werden daher bereits seit längerem Anstrengungen unternommen, Abdeckroste einzusetzen, die leichter kontruiert sind.Efforts have therefore been made for some time to use cover gratings which are more easily controlled.

Aufgabe der vorliegenden Erfindung ist es daher, einen Abdeckrost anzugeben, der bei verhältnismäßig geringem Gewicht eine hohe Stabilität aufweist und der auch sowohl flächige als auch punktuelle Belastungen zuverlässig aufnehmen kann, ohne daß dabei das Schluckvermögen wesentlich beeinträchtigt wird.The object of the present invention is therefore to provide a cover grate which has a high stability with a relatively low weight and which can also reliably absorb both area and point loads without the swallowing capacity being significantly impaired.

Diese Aufgabe wird durch die Merkmale des Anspruches 1 und/oder 4 gelöst.This object is solved by the features of claims 1 and / or 4.

Wie aus den beiliegenden Zeichnungen hervorgeht, ist eine Abdeckung 30 auf einer Rinne 1 angebracht. Die Abdeckung 30 weist Öffnungen 31, 31' auf, die durch Rippen 37 voneinander getrennt sind.As is apparent from the accompanying drawings, a cover 30 is attached to a gutter 1. The cover 30 has openings 31, 31 'which are separated from one another by ribs 37.

Die Längsränder 32, 32' der Abdeckung 30 weisen an einem Längsrand 32' Einhaköffnungen 39 auf, die nur in die Oberfläche der Abdeckung 30 eingesenkt sind, so daß unter den Einhaköffnungen Haltestücke 29 liegen. Die Rinne 1 ist mit Einhakelementen 13 ausgestattet, welche in die Einhaköffnungen 39 inserieren und somit auf den Haltestücken 29 zu liegen kommen. Am anderen Längsrand 32 ist die Abdeckung 30 mit Öffnungen 39' versehen, welche die gesamte Abdeckung 30 durchqueren, so daß am anderen Längsrand 32 keine Haltestücke 29 liegen.The longitudinal edges 32, 32 'of the cover 30 have hooking openings 39 on a longitudinal edge 32', which are only sunk into the surface of the cover 30, so that holding pieces 29 lie below the hooking openings. The channel 1 is equipped with hooking elements 13, which insert into the hooking openings 39 and thus come to rest on the holding pieces 29. At the other longitudinal edge 32, the cover 30 is provided with openings 39 'which pass through the entire cover 30, so that there are no holding pieces 29 on the other longitudinal edge 32.

Bei der in den Abbildungen gezeigten Ausführungsform sind zwei voneienander beabstandete Ausnehmungen 31 in der Abdeckung 30 über einen Schlitz 33 bis zum Längsrand 32 durchgeführt. Dieser Schlitz 33 weist an seinem dem Rand 32 zugewandten Ende eine Halteausnehmung 38 auf, welche so geformt ist, daß eine an der Rinne befestigte Nase 26 im wesentlichen formschlüssig hineinpaßt. Dadurch ist eine Verschiebung der Abdeckung 30 in Längsrichtung der Rinne wirksam verhindert.In the embodiment shown in the figures, two recesses 31 spaced apart from one another are made in the cover 30 via a slot 33 up to the longitudinal edge 32. This slot 33 has at its end facing the edge 32 a holding recess 38 which is shaped such that a nose 26 fastened to the groove fits essentially in a form-fitting manner. This effectively prevents the cover 30 from moving in the longitudinal direction of the channel.

Die Nase 26 weist, wie in Fig. 2 gezeigt, über und unter sich einen Freiraum auf.As shown in FIG. 2, the nose 26 has a free space above and below it.

Der Schlitz 33 bzw. die dazugehörige Öffnung 31 ist mit Führungsschienen 36, 36' versehen, die nach innen, in den Schlitz 33 bzw. die Öffnung 31 ragen. Die Schienen 36, 36' sind mit Kerben 68 ausgestattet.The slot 33 or the associated opening 31 is provided with guide rails 36, 36 'which project inwards into the slot 33 or the opening 31. The rails 36, 36 'are equipped with notches 68.

In die mit Schlitzen 33 versehenen Öffnungen 31 ist jeweils ein Riegel 60 eingesetzt, der einen doppel-T-förmigen Querschnitt und eine obere Deckplatte 64 aufweist, wie dies in der europäischen Hauptanmeldung P 93 119 304.9 beschrieben ist.In each of the openings 31 provided with slots 33, a bolt 60 is inserted, which has a double-T-shaped cross section and an upper cover plate 64, as described in the European main application P 93 119 304.9.

Die Höhe der Oberfläche 70 der Deckplatte 64 ist etwas geringer als diejenige der Abdeckung 30, so daß beim Überfahren der Abdeckung keine Kraft auf den Riegel bzw. seine Oberfläche 70 wirkt. Darüber hinaus sind auf der Abdeckung 30 über deren Oberfläche 34 hervorragende Noppen 117, 118 vorgesehen, was zum einen die Rutschsicherheit erhöht, zum anderen wiederum eine Belastung des Riegels 60 beim Überfahren verringert.The height of the surface 70 of the cover plate 64 is somewhat less than that of the cover 30, so that no force acts on the bolt or its surface 70 when the cover is passed over. In addition, excellent knobs 117, 118 are provided on the cover 30 over its surface 34, which on the one hand increases the slip resistance and on the other hand reduces the load on the latch 60 when it is passed over.

Der Riegel 60 wird vorzugsweise aus Metall großer Festigkeit (z.B. aus einer Aluminium-Druckgußlegierung) gefertigt, wobei seine Oberfläche passiviert ist, um Korrosion zu vermeiden.The latch 60 is preferably made of high strength metal (e.g. die-cast aluminum) with its surface passivated to avoid corrosion.

Wie aus den Figuren 1, 2 und 3 ersichtlich, ist die Rinne 1 bezüglich der Nasen 26 auf beiden Seiten gleichartig bzw. symmetrisch ausgebildet. Demzufolge sind am Längsrand 32' gegenüber dem Längsrand 32, an welchem sich die Riegel 60 befinden, Ausnehmungen 47 vorgesehen, in welchen die am Längsrand 32' an sich nicht benötigten Nasen 26 Platz finden. Auf diese Weise ist gewährleistet, daß man die Abdeckung 30 in beliebiger Orientierung auf die Rinne 1 aufsetzen kann.As can be seen from FIGS. 1, 2 and 3, the channel 1 is of identical or symmetrical design with respect to the lugs 26 on both sides. Accordingly, recesses 47 are provided on the longitudinal edge 32 'relative to the longitudinal edge 32, on which the bolts 60 are located, in which recesses 26 which are not required per se on the longitudinal edge 32' can be accommodated. In this way it is ensured that the cover 30 can be placed on the channel 1 in any orientation.

Beim Aufsetzen einer Abdeckung 30 einer Rinne 1 geht man nun so vor, daß man die Abdeckung 30 zunächst kippt und mit den Haltestücken 29 unter die Einhakelemente 13 hakt. Danach wird die Abdeckung 30 bei zurückgeschobenen Riegeln 60 (in Fig. 1 nach rechts geschoben) vollständig aufgelegt. Dann werden die Riegel 60 geschlossen (in Fig. 1 nach links geschoben). Zum Öffnen wird in der umgekehrten Reihenfolge vorgegangen.When putting on a cover 30 of a channel 1, the procedure is now that the cover 30 is first tilted and hooked under the hooking elements 13 with the holding pieces 29. Thereafter, the cover 30 is completely placed with the bars 60 pushed back (pushed to the right in FIG. 1). Then the latches 60 are closed (pushed to the left in FIG. 1). To open, proceed in the reverse order.

In den Fig. 4 bis 8 ist eine Ausführungsform des Abdeckrostes 30 genauer dargestellt. Demgemäß weist der Abdeckrost 30 einen ersten und einen zweiten Auflageabschnitt 105, 106 auf, die seitlich des Abdeckrostes 30 angeordnet sind. Sie sind voneinander beabstandet und verlaufen parallel zueinander in Längsrichtung des Abdeckrostes 30. Der Abdeckrost 30 liegt mit den Auflageabschnitten 105 und 106, wie in Fig. 7 schematisch dargestellt ist, auf einer hier nicht näher gezeigten Entwässerungsrinne 1 auf.4 to 8, an embodiment of the cover grate 30 is shown in more detail. Accordingly, the cover grate 30 has a first and a second support section 105, 106 which are arranged laterally of the grating 30. They are spaced apart from one another and run parallel to one another in the longitudinal direction of the cover grate 30. The cover grate 30 lies with the support sections 105 and 106, as shown schematically in FIG.

Die beiden Auflageabschnitte 105 und 106 sind durch eine Vielzahl von in Längsrichtung des Abdeckrostes 101 voneinander beabstandeten Stegen 107 miteinander verbunden. Durch die Beabstandung der Stege 107 werden Einlaufschlitze 109 gebildet, auf die später noch eingegangen wird. An der Unterseite der Stege 107 sind sich nach unten, in die Entwässerungsrinne erstreckende Stützabschnitte 115 vorgesehen, deren Höhe größer ist als die Dicke der Auflageabschnitte 105, 106. Die Stützabschnitte 115 erstrecken sich bei der konkreten Ausführungsform gemäß den Fig. 6 und 7 im wesentlichen vom Bereich eines Auflageabschnitts 105 zum Bereich des gegenüberliegenden Auflageabschnitts 106 und verstärken die Stege 107 derart, daß auch bei einer extrem hohen Belastung auf einzelne Stege 107 ein Durchbrechen des jeweiligen Steges 107 bzw. eine Beschädigung des Abdeckrostes 30 nicht zu befürchten ist.The two support sections 105 and 106 are connected to one another by a plurality of webs 107 spaced apart from one another in the longitudinal direction of the cover grate 101. The spacing of the webs 107 forms inlet slots 109, which will be discussed later. On the underside of the webs 107 there are support sections 115 extending downward into the drainage channel, the height of which is greater than the thickness of the support sections 105, 106. The support sections 115 essentially extend in the specific embodiment according to FIGS. 6 and 7 from the area of a support section 105 to the area of the opposite support section 106 and reinforce the webs 107 in such a way that even with an extremely high load on individual webs 107 there is no need to fear breaking through the respective web 107 or damage to the cover grating 30.

Zwischen den Stegen 107 sind Brückenabschnitte 111 vorgesehen, die jeweils zwei nebeneinanderliegende Stege 107 miteinander verbinden. Durch die Brückenabschnitte 111 werden die Einlaufschlitze 109 gemäß den Fig. 4 und 6 in zwei Teileinlaufschlitze geteilt, wobei durch die außermittige Anordnung der Brückenabschnitte 111 die beiden Teileinlaufschlitze 109 eine unterschiedliche Länge aufweisen. In Längsrichtung des Abdeckrostes 30 gesehen sind die Brückenabschnitte 111 derart abwechselnd zum ersten bzw. zum zweiten Auflageabschnitt 105, 106 verschoben angeordnet, daß sich längere und kürzere Einlaufschlitze abwechseln.Bridge sections 111 are provided between the webs 107, each connecting two adjacent webs 107 to one another. 4 and 6 are divided into two partial inlet slots by the bridge sections 111, the two partial inlet slots 109 having a different length due to the eccentric arrangement of the bridge sections 111. Seen in the longitudinal direction of the cover grating 30, the bridge sections 111 are alternately displaced in relation to the first and second support sections 105, 106 in such a way that longer and shorter inlet slots alternate.

Insbesondere sind bei der vorliegenden, konkreten Ausführungsform gemäß den Fig. 4 bis 7 die Brückenabschnitte derart angeordnet, daß sie abwechselnd mit ihren den ersten und den zweiten Auflageabschnitten 105, 106 zugewandten Rändern an eine Linie 113 in Längsrichtung des Abdeckrostes 30 im wesentlichen angrenzen. Dadurch ergibt sich ein mäanderförmiger Weg, der zwischen den Teil-Einlaufschlitzen hindurchführt und aus jeweils aufeinanderfolgenden Brückenabschnitten 111 und Stegen 107 zusammengesetzt ist.In particular, in the present, specific embodiment according to FIGS. 4 to 7, the bridge sections are arranged in such a way that they alternate with their first and second Border sections 105, 106 facing edges essentially adjoin a line 113 in the longitudinal direction of the cover grate 30. This results in a meandering path that leads between the partial inlet slots and is composed of successive bridge sections 111 and webs 107.

Gerade diese Konstruktionsmaßnahme hat sich als äußerst stabilisierend erwiesen, so daß der vorliegende, durch die besondere Anordnung der Brückenabschnitte 111 verstärkte Abdeckrost 30 gegenüber einem herkömmlichen Abdeckrost eine wesentlich höhere Stabilität aufweist und somit größeren Belastungen standhalten kann, ohne daß der Abdeckrost bzw. einzelne Stege beschädigt werden. Gleichzeitig wird auch die Entwässerungsleistung bei überschießendem Wasser verbessert.This construction measure has proven to be extremely stabilizing, so that the present cover grille 30, which is reinforced by the special arrangement of the bridge sections 111, has a considerably higher stability than a conventional cover grate and can therefore withstand greater loads without the cover grate or individual webs being damaged become. At the same time, the drainage performance is improved in the event of excess water.

Auf der begeh- und überfahrbaren Oberfläche 103 des Abdeckrostes 30 sind, wie in den Fig. 4 bis 7 gezeigt ist, eine Vielzahl von Noppen 117, 118 angeordnet, die nach oben vorstehen und die Griffestigkeit des Abdeckrostes 30 erhöhen.A number of knobs 117, 118 are arranged on the surface 103 of the grating 30 that can be walked on and driven over, as shown in FIGS. 4 to 7, which protrude upwards and increase the grip of the grating 30.

Dabei werden zwei Gruppen von Noppen unterschieden. Die ersten Noppen 117 sind in den Bereichen der Auflageabschnitte 105, 106 angeordnet, und zwar derart, daß ein äußerer Teil der Noppen 121 über die Auflageabschnitte 105 bzw. 106 und der andere, innere Teil 119 über die jeweils zugeordneten Stege 107 ragt. Dies ist insbesondere in den Fig. 6 und 7 gut zu erkennen. Mittels dieser Noppen 117 werden die Übergangsbereiche zwischen den Auflageabschnitten 105, 106 und den Stegen 107 zusätzlich verstärkt, wobei ein Stabilitätsgewinn erzielt wird.A distinction is made between two groups of knobs. The first knobs 117 are arranged in the regions of the support sections 105, 106, in such a way that an outer part of the knobs 121 projects over the support sections 105 and 106 and the other, inner part 119 projects over the respectively assigned webs 107. This can be seen particularly well in FIGS. 6 and 7. By means of these knobs 117, the transition areas between the support sections 105, 106 and the webs 107 are additionally reinforced, a gain in stability being achieved.

Die zweite Gruppe von Noppen 118 erzielt die gleiche Wirkung in den Bereichen, in denen die Brückenabschnitte 111 in die Stege 107 übergehen (Übergangsbereiche). Wie insbesondere der Fig. 4 zu entnehmen ist, sind die zweiten Noppen 118 ebenfalls auf den Stegen 107, und zwar in Ausrichtung mit den ersten Noppen 117, angeordnet, wobei der innere Noppenteil in einem Übergangsbereich von zumindest einem Brückenabschnitt 111 angeordnet ist und der andere Noppenteil gerade nicht den Übergangsbereich überlappt. Auf diese Weise wird der Übergangsbereich zwischen Brückenabschnitten 111 und Stegen 107 verstärkt.The second group of knobs 118 achieves the same effect in the areas in which the bridge sections 111 merge into the webs 107 (transition areas). As can be seen in particular from FIG. 4, the second knobs 118 are likewise arranged on the webs 107, specifically in alignment with the first knobs 117, the inner knob part being arranged in a transition region from at least one bridge section 111 and the other knob part just does not overlap the transition area. In this way, the transition area between bridge sections 111 and webs 107 is strengthened.

Es ist dabei klar, daß die vorgenannt angesprochenen Verstärkungsmaßnahmen, nämlich die entsprechende Positionierung der Noppen und die Anordnung von gegeneinander versetzten Brückenabschnitten sowohl separat als auch kombiniert vorgesehen sein können.It is clear that the aforementioned reinforcement measures, namely the corresponding positioning of the knobs and the arrangement of staggered bridge sections, can be provided both separately and in combination.

Jede dieser Maßnahmen ermöglicht durch den durch sie erreichten Stabilitätsgewinn für den Abdeckrostes, daß beispielsweise die Stützabschnitte 115 schmäler ausgeführt werden können, was eine Materialeinsparung und somit eine Reduktion der Herstellungskosten zur Folge hat. Im übrigen ist bei den vorgenannt angegebenen Abdeckrosten eine Beschädigung bzw. eine Beschädigung einzelner Stege auch durch eine übermäßige Belastung nicht zu befürchten.Each of these measures, by means of the gain in stability for the covering grate which they achieve, makes it possible, for example, for the support sections 115 to be made narrower, which results in a saving in material and thus a reduction in the production costs. Moreover, there is no risk of damage or damage to individual webs, even due to excessive loading, in the case of the aforementioned cover grids.

Gemäß der Fig. 8 ist eine zweite Ausführungsform eines Abdeckrostes angegeben, der insbesondere für breitere Ausführungen verwendet wird.According to FIG. 8, a second embodiment of a cover grate is specified, which is used in particular for wider designs.

Auch bei dieser Ausführungsform weist der Abdeckrost 101 analog zur ersten Ausführungsform - erste und zweite Auflageabschnitte 105, 106 sowie diese verbindende und voneinander in Längsrichtung beabstandete Stege 107 auf.In this embodiment as well, the cover grille 101 has, analogous to the first embodiment, first and second support sections 105, 106 and webs 107 connecting them and spaced apart in the longitudinal direction.

Der Unterschied zur ersten Ausführungsform ergibt sich dadurch, daß zwei nebeneinanderliegende Stege 107 nun nicht mehr durch nur einen Brückenabschnitt 111, sondern durch zwei Brückenabschnitte 111 verbunden sind. Dadurch wird jeder Einlaufschlitz 109 in drei Teil-Einlaufschlitze aufgeteilt.The difference to the first embodiment results from the fact that two adjacent webs 107 are no longer connected by only one bridge section 111, but by two bridge sections 111. As a result, each inlet slot 109 is divided into three partial inlet slots.

Durch die Anordnung von jeweils zwei Brückenabschnitten 111 zur Verbindung zweier nebeneinanderliegender Stege 107 werden zwei mäanderförmige Linien gebildet, die sich in Längsrichtung des Abdeckrostes 30 durch die Teil-Einlaufschlitze schlängeln. Die beiden mäanderförmigen Linien verlaufen im wesentlichen parallel zueinander und sind bezüglich einer Mittelsymmetrielinie A spiegelbildlich zueinander ausgebildet.By arranging two bridge sections 111 each for connecting two adjacent webs 107, two meandering lines are formed which wind through the partial inlet slots in the longitudinal direction of the cover grate 30. The The two meandering lines run essentially parallel to one another and are mirror images of one another with respect to a center line of symmetry A.

Die einer mäanderförmigen Linie zugehörigen Brückenabschnitte 111 sind zueinander wie die Brückenabschnitte der ersten Ausführungsform angeordnet. Insbesondere grenzen sie abwechselnd mit ihren den ersten und den zweiten Auflageabschnitten 105, 106 zugewandten Rändern an eine Linie 113 im wesentlichen an.The bridge sections 111 belonging to a meandering line are arranged with respect to one another like the bridge sections of the first embodiment. In particular, they alternately essentially adjoin a line 113 with their edges facing the first and the second support sections 105, 106.

Die der anderen mäanderförmigen Linie zugeordneten Brückenabschnitte 111 sind analog zueinander angeordnet.The bridge sections 111 assigned to the other meandering line are arranged analogously to one another.
