A drainage channel comprising a channel body (10) formed in one piece from polyester concrete and having a bottom (11) and two side walls (12, 13) spaced from each other, a cover member (18) supported on the abutment surfaces of the side walls (12, 13) and closing the upper surface of the channel body (10), and at least one interlocking element (24) in engagement with both side walls (12, 13) having a threaded bolt (25) passed through an opening in the cover member (18) and actuable from the upper surface of the cover member (18) engaging therein, characterized in that the interlocking element comprises a bar (24) in the form of a toggle which is pivotable by rotation of the threaded bolt (25), and in that at least two recesses (21, 22) opposite to each other are formed in the channel body (10) in such a manner that the toggle-like bar (24) is capable of being respectively pivoted into or out of the recesses (21, 22) by its ends upon rotation of the bolt (25).

Description

Die Erfindung bezieht sich auf eine Entwässerungsrinne mit einem einteilig aus Polyesterbeton geformten einen Boden und zwei beabstandete Seitenwände aufweisenden Rinnenkörper, einer sich auf Auflageflächen der Seitenwände abstützenden die Oberseite des Rinnenkörpers verschließenden Abdeckung und mindestens einem mit beiden Seitenwänden in Eingriff stehenden Verriegelungselement, in dem ein durch eine Öffnung der Abdeckung hindurchgeführter, von der Oberseite der Abdeckung betätigbarer Ge- windebolzen in Eingriff ist.The invention relates to a drainage channel with a one-piece molded from polyester concrete and a bottom and two spaced side walls having channel body, a supporting on bearing surfaces of the side walls covering the top of the channel body and at least one locking element in engagement with both side walls, in which a through an opening of the cover is passed through threaded bolts which can be actuated from the upper side of the cover.

Eine derartige Entwässerungsrinne ist bekannt (DE-U-7 936 522). Das Verriegelungselement ist eine Traverse, die bei der Ausformung des Rinnenkörpers in die Seitenwände des Rinnenkörpers eingebettet ist. Es weist eine mittige Gewindeöffnung auf, in die ein durch die Öffnung in der Abdeckung hindurchgesteckter Gewindebolzen eingeschraubt wird. Diese Befestigungsart weist einige Nachteile auf. Die Einformung der Traversen erfordert einen zusätzlichen Fertigungsaufwand. Ferner stören die Traversen, wenn die Entwässerungsrinne bei entfernter Abdeckung gereinigt werden soll. Schließlich kann die Befestigung der Abdeckung mit Schwierigkeiten behaftet sein. Die Abdeckung muß derart auf dem Rinnenkörper plaziert werden, daß der Schraubenbolzen exakt zur Gewindebohrung in der Traverse ausgerichtet ist. Bei einer Fehlausrichtung erfordert es ein mühsames Hin- und Herschieben, bis die Ausrichtung erreicht ist, vor allem wenn die Abdeckung relativ schwer ist. Die Ausrichtung wird auch dadurch erschwert, daß die Gewindebohrung mit dem Auge kaum auszumachen ist.Such a drainage channel is known (DE-U-7 936 522). The locking element is a cross member that is embedded in the side walls of the channel body when the channel body is formed. It has a central threaded opening into which a threaded bolt inserted through the opening in the cover is screwed. This type of attachment has some disadvantages. The shaping of the trusses requires additional manufacturing effort. The trusses also interfere when the drainage channel is to be cleaned with the cover removed. Finally, the attachment of the cover can be difficult. The cover must be placed on the channel body in such a way that the screw bolt is exactly aligned with the threaded hole in the crossbar. In the event of misalignment, laboriously pushing it back and forth until alignment is achieved, especially if the cover is relatively heavy. The alignment is also made more difficult by the fact that the threaded hole can hardly be seen with the eye.

Es sind aus Metallguß geformte Rinnenkörper zur Verlegung von Kabeln oder anderen Leitungen bekannt, bei denen an diagonalen Ecken der Abdeckung kleine Verriegelungshebel schwenkbar angebracht sind, die in Ausnehmungen der Rinnenwandung einführbar sind (FR-A-1 430 358). Eine Verspannung der kleinen Verriegelungshebel erfolgt nicht. Entwässerungsrinnen für die Entwässerung von Straßen, Wegen und Plätzen, die aus einzelnen Rinnenkörpern zusammengesetzt und normalerweise aus Beton oder Polyesterbeton geformt sind und mit Rosten aus Gußeisen oder Eisenblech abgedeckt sind, müssen gewährleisten, daß die Abdeckungen durch den rollenden Verkehr nicht herausgerissen werden und Personen gefährden. Bei der Rinne der zuletzt genannten Art können jedoch die Riegel durch Erschütterungen relativ leicht in die Entriegelungsstellung gebracht werden.Channel bodies formed from cast metal are known for laying cables or other lines, in which small locking levers are pivotally attached to diagonal corners of the cover and can be inserted into recesses in the channel wall (FR-A-1 430 358). The small locking levers are not braced. Drainage channels for the drainage of streets, paths and squares, which are composed of individual channel bodies and are usually made of concrete or polyester concrete and covered with grates made of cast iron or sheet iron, must ensure that the covers are not torn out by rolling traffic and endanger people . In the channel of the last-mentioned type, however, the bolts can be brought into the unlocking position relatively easily by vibrations.

Der Erfindung liegt die Aufgabe zugrunde, für eine Entwässerungsrinne aus Polyesterbeton eine wirksam befestigbare Abdeckung zu schaffen, die gleichwohl etwa zu Säuberungszwecken entfernt werden kann und eine leichte Säuberung ermöglicht.The invention has for its object to provide an effectively attachable cover for a drainage channel made of polyester concrete, which can nevertheless be removed for cleaning purposes and enables easy cleaning.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Verriegelungselement ein knebelartiger durch Drehung des Gewindebolzens verschwenkbarer Riegel ist und in die Seitenwände des Rinnenkörpers mindestens zwei einander gegenüberliegende Ausnehmungen so eingeformt sind, daß der knebelartige Riegel bei Drehung des Gewindebolzens mit den Enden in die Ausnehmungen einschwenkbar bzw. aus diesen herausschwenkbar ist.This object is achieved in that the locking element is a gag-like bolt pivotable by rotation of the threaded bolt and at least two mutually opposite recesses are formed in the side walls of the channel body so that the gag-like bolt can be pivoted with the ends into the recesses when the threaded bolt rotates or is pivotable out of these.

Bei der Erfindung wurde erkannt, daß es nicht notwendig ist, zusätzliche Auflagen, sogenannte Zargen, mit der Oberseite des Rinnenkörpers zu verbinden, um eine wirksame Verriegelung der Abdeckung zu erhalten. Vielmehr wird bei der Erfindung der Rinnenkörper selbst für eine lösbare Verriegelung herangezogen, indem in die Seitenwände gegenüberliegende Verriegelungsausnehmungen eingeformt werden, in die die Enden des schwenkbaren Verriegelungshebels hineingeschwenkt werden. Durch Verdrehung des Schraubenbolzens wird der Riegel nicht nur in die Ausnehmungen hinein- bzw. aus diesen herausgeschwenkt, sondern auch gegenüber der Abdeckung vorgespannt, indem sich die Enden des Riegels gegen die Ausnehmungsbegrenzungen legen. Auf diese Weise kann die Abdeckung klapper- und erschütterungsfrei gegenüber dem Rinnenkörper vorgespannt und wirksam gehalten werden. Soll die Abdeckung entfernt werden, wird der Schraubenbolzen in die andere Richtung gedreht, bis der Klemmeingriff aufgehoben wird und der Riegel aus den Ausnehmungen herausschwenkt.In the invention it was recognized that it is not necessary to connect additional supports, so-called frames, to the top of the channel body in order to obtain an effective locking of the cover. Rather, in the invention, the channel body itself is used for releasable locking, in that opposing locking recesses are formed in the side walls, into which the ends of the pivotable locking lever are pivoted. By turning the screw bolt, the bolt is not only pivoted into or out of the recesses, but is also pretensioned with respect to the cover by the ends of the bolt laying against the recess boundaries. In this way, the cover can be pretensioned against the channel body without rattling and shaking and can be kept effective. If the cover is to be removed, the screw bolt is turned in the other direction until the clamping engagement is released and the bolt swings out of the recesses.

Der Gewindebolzen kann erfindungsgemäß entweder drehfest oder über eine Gewindeverbindung mit dem Riegel verbunden. sein.According to the invention, the threaded bolt can be connected to the bolt either in a rotationally fixed manner or via a threaded connection. be.

Die gegenüberliegenden Ausnehmungen sind vorzugsweise im Endbereich des Rinnenkörpers vorgesehen. Sie sind ferner nach einer Ausgestaltung der Erfindung jeweils im Einlauf- bzw. Auslaufbereich des knebelartigen Riegels angeschrägt. Dadurch wird es möglich, die Enden des Riegels in die gesamte Tiefe der Ausnehmung eintreten zu lassen, ohne daß die Ausnehmung unnötig lang ausgeführt werden muß, was zu einer entsprechenden Schwächung der Stabilität der Rinnenwand führen würde.The opposite recesses are preferably provided in the end region of the channel body. Furthermore, according to an embodiment of the invention, they are each beveled in the inlet or outlet area of the toggle-type latch. This makes it possible to let the ends of the bolt enter the entire depth of the recess without the recess having to be made unnecessarily long, which would lead to a corresponding weakening of the stability of the channel wall.

Dem gleichen Ziel dient eine weitere Ausgestaltung der Erfindung, nach der die einander gegenüberliegenden Ausnehmungen gegeneinander versetzt angeordnet sind.A further embodiment of the invention serves the same goal, according to which the mutually opposite recesses are arranged offset from one another.

Ein Ausführungsbeispiel der Neuerung wird nachfolgend anhand von Zeichnungen näher erläutert.

  • Figur 1 zeigt eine Draufsicht auf eine Entwässerungsrinne nach der Neuerung,
  • Figur 2 zeigt einen Schnitt durch die Entwässerungsrinne nach Fig. 1 entlang der Linie 2-2.
An embodiment of the innovation is explained in more detail below with reference to drawings.
  • FIG. 1 shows a top view of a drainage channel after the innovation,
  • Figure 2 shows a section through the drainage channel of Fig. 1 along the line 2-2.

Bevor auf die in den Zeichnungen dargestellten Einzelheiten näher eingegangen wird, sei vorangestellt, daß jedes der gezeigten Merkmale für sich oder in Verbindung mit Merkmalen der Ansprüche von neuerungswesentlicher Bedeutung ist.Before going into the details shown in the drawings, it should be assumed that each of the features shown for itself or in connection with features of the claims is of essential importance for innovation.

Die in den Figuren 1 und 2 dargestellte Entwässerungsrinne wird allgemein mit 10 bezeichnet. Sie weist einen Boden 11 sowie zwei parallele Seitenwände 12, 13 auf, die an der Außenseite mit bis zum Boden 11 reichenden Aussparungen 14 versehen sind zwecks Einsparung an Material, z. B. Poiyesterbeton, aus dem die Rinne 10 gegossen ist. Boden 11 und Seitenwände 12, 13 bilden einen Entwässerungskanal 15, der an der Unterseite, wie aus Fig. 2 zu ersehen, abgerundet ist.The drainage channel shown in Figures 1 and 2 is generally designated 10. It has a bottom 11 and two parallel side walls 12, 13, which are provided on the outside with recesses 14 reaching to the bottom 11 in order to save material, e.g. B. Poiyester concrete from which the channel 10 is poured. Bottom 11 and side walls 12, 13 form a drainage channel 15, which is rounded on the underside, as can be seen in FIG. 2.

Auf den einander zugekehrten Innenseiten der Seitenwände 12 und 13 sind Absätze 16, 17 geformt, auf der eine Rinnenabdeckung 18, die in Fig. 2 gestrichelt dargestellt ist, aufliegen kann. Die Rinnenabdeckung 18 ist beispielsweise aus einem geeigneten Metallguß hergestellt und besitzt Einlauföffnungen, die hier nicht gezeigt sind. Die seitliche Begrenzung der Abdeckung 18 erfolgt über die Wandabschnitte 19, 20 der Rinnenwände 12, 13. Die Oberseite der Abdeckung 18 fluchtet mit der Oberseite der Abschnitte 19, 20.On the inner sides of the side walls 12 and 13 facing one another, shoulders 16, 17 are formed, on which a channel cover 18, which is shown in broken lines in FIG. 2, can rest. The channel cover 18 is made, for example, from a suitable metal casting and has inlet openings which are not shown here. The lateral limitation of the cover 18 takes place via the wall sections 19, 20 of the channel walls 12, 13. The upper side of the cover 18 is aligned with the upper side of the sections 19, 20.

Unterhalb der Schultern oder Absätze 16, 17 sind zwei Paar einander gegenüberliegende Ausnehmungen 21, 22 von der Innenseite in die Seitenwände 12 und 13 eingeformt. In Fig. 1 ist die Ausnehmung 21 durch Wegbrechung dargestellt, wobei die übrigen Ausnehmungen gestrichelt eingezeichnet sind. Wie aus Fig. 1 zu erkennen, ist die Vorderseite der Ausnehmungen 21, 22 etwas angeschrägt, wie bei 23 bzw. 24 dargestellt. Ferner sind die Ausnehmungen 21, 22 gegeneinander etwas versetzt.Below the shoulders or shoulders 16, 17, two pairs of opposing recesses 21, 22 are formed into the side walls 12 and 13 from the inside. In Fig. 1, the recess 21 is shown by breaking away, the other recesses are shown in dashed lines. As can be seen from Fig. 1, the front of the recesses 21, 22 is slightly chamfered, as shown at 23 and 24, respectively. Furthermore, the recesses 21, 22 are slightly offset from one another.

Aus Fig. 2 ist ferner zu erkennen, daß ein knebelartiger Riegel 24 mit Hilfe eines Gewindebolzens 25 drehbar in der Abdeckung 18 gelagert ist. Die Abdeckung 18 besitzt von der Oberseite her eine Ausnehmung 26, die eine Mutter 27 aufnimmt. Durch Verdrehung am Gewindebolzen 25 erfolgt eine Verschwenkung des Riegels 24. Bei einer Drehung im Uhrzeigersinn treten die Enden des Riegels 24 in die Ausnehmung 21 bzw. 22 ein, und zwar im Uhrzeigersinn, so daß sie an der schrägen Einlaufkante 23, 24 entlang gleiten können bis zum Anschlag mit der hinteren Kante 28 bzw. 29 der Ausnehmungen 21 und 22. Eine Verschwenkung des Riegels 24 in entgegengesetzter Richtung hebt die Verriegelung auf und die Abdeckung 18 kann ohne weiteres von dem Rinnenkörper 10 abgehoben werden, beispielsweise zur Reinigung des damit völlig freien Kanals 15.From Fig. 2 it can also be seen that a gag-like bolt 24 is rotatably mounted in the cover 18 by means of a threaded bolt 25. The cover 18 has a recess 26 from the top, which receives a nut 27. By turning the threaded bolt 25, the bolt 24 is pivoted. With a clockwise rotation, the ends of the bolt 24 enter the recesses 21 and 22, respectively, clockwise, so that they can slide along the inclined leading edge 23, 24 to the stop with the rear edge 28 or 29 of the recesses 21 and 22. A pivoting of the bolt 24 in the opposite direction cancels the lock and the cover 18 can easily be lifted off the channel body 10, for example for cleaning the completely free one Channel 15.
