Description

Die Erfindung bezieht sich auf eine aus Metall geformte Zarge für Entwässerungsrinnen mit zwei nach unten weisenden, parallel und im Abstand verlaufenden Schenkeln, die zwischen sich einen Kanal bilden, in den das Material im oberen Bereich der Rinnenwand eingeformt ist und die über einen Steg miteinander verbunden sind, dessen Oberseite eine Auflagefläche für eine Rinnenabdeckung bildet, und mit einem sich vom Steg nach oben erstreckenden Schenkel zurseitlichen HalterungderRinnenabdeckung.The invention relates to a metal frame for drainage channels with two downward, parallel and spaced legs that form a channel between them, into which the material is molded in the upper region of the channel wall and which are connected to one another via a web whose top forms a support surface for a channel cover and with a leg extending upwards from the web for lateral support of the channel cover.

Es ist eine Entwässerungsrinne bekannt, bei der an den oberen Rändern Halteteile angeordnet sind, die außer an der Oberseite auch an einer Seitenwandfläche des betreffenden Randes anliegen (DE-C-1 955 737). Derartige Halteteile dienen gleichzeitig dem Kantenschutz der Entwässerungsrinne und als Auflager für die Abdeckung, beispielsweise einen Rinnenrost. Bei der bekannten Entwässerungsrinne wird das Halteteil nachträglich befestigt, beispielsweise durch Verschraubung mit der äußeren Seitenfläche der Wand des Rinnenkörpers. Entwässerungsrinne einerseits und Halteseil andererseits werden bei der bekannten Konstruktion als Einzelteile gefertigt, so daß eine zusätzliche Montage an der Baustelle notwendig ist.A drainage channel is known, in which holding parts are arranged on the upper edges, which also rest on a side wall surface of the relevant edge in addition to the upper side (DE-C-1 955 737). Such holding parts serve at the same time to protect the edge of the drainage channel and as a support for the cover, for example a channel grate. In the known drainage channel, the holding part is subsequently attached, for example by screwing to the outer side surface of the wall of the channel body. Drainage gutter on the one hand and tether on the other hand are manufactured as individual parts in the known construction, so that an additional assembly at the construction site is necessary.

Es ist ferner bekannt, Zargen für Entwässerungsrinnen mit Verankerungsprofilen zu versehen, die in den Rinnenkörper eingeformt werden. In Verbindung mit Entwässerungsrinnen aus Polyesterbeton und auch aus der DE-U-7 122 579 ist die eingangs beschriebene Zargenkonstruktion bekannt geworden. Der zwischen den nach unten weisenden Schenkeln gebildete Kanal ist im Querschnitt einem Schwalbenschwanzprofil ähnlich, so daß durch den in den Kanal eingegossenen Polyesterbeton eine wirksame Verankerung der Zarge mit dem Rinnenschenkel gewährleistet ist.It is also known to provide frames for drainage channels with anchoring profiles that are molded into the channel body. In connection with drainage channels made of polyester concrete and also from DE-U-7 122 579, the frame construction described at the beginning has become known. The channel formed between the legs pointing downward is similar in cross-section to a dovetail profile, so that an effective anchoring of the frame with the channel leg is ensured by the polyester concrete cast into the channel.

Insbesondere bei Straßen und Wegen, die für Schwerlastverkehr ausgelegt sind, ist eine besonders stabile Rinnenkonstruktion bzw. Halterung der Abdeckungen, z. B. Rinnenrosten, erforderlich. Besonders kritisch sind die auf die Rinnenabdeckung einwirkenden Kräfte, die durch häufiges und schnelles Überfahren, teilweise auch mit großen Radlasten, entstehen. Der dabei auftretende sehr komplexe Lastfall beinhaltet gleichzeitige Beanspruchungen aus wechselnden Zug- und Druckkräften, Biegekräften und Scherkräften. Durch die Verzahnung zwischen Zarge und Rinnenkörper wird zwar zwischen diesen beiden Teilen eine feste Verbindung erhalten, andererseits wird der Querschnitt der Rinnenwand im kritischen Bereich reduziert (Kerbwirkung).Particularly on roads and paths that are designed for heavy-duty traffic, a particularly stable channel construction or mounting of the covers, e.g. B. channel gratings required. The forces acting on the channel cover, which arise from frequent and rapid running over, sometimes with large wheel loads, are particularly critical. The very complex load case that occurs includes simultaneous stresses from changing tensile and compressive forces, bending forces and shear forces. The teeth between the frame and the channel body provide a firm connection between these two parts, but on the other hand the cross-section of the channel wall is reduced in the critical area (notch effect).

Der Erfindung liegt daher die Aufgabe zugrunde, eine aus Metall geformte Zarge für Entwässerungsrinnen zu schaffen, die integriert mit der Entwässerungsrinne hergestellt werden kann, jedoch die Aufnahme hoher wechselnder Zug- und Druckkräfte, Biegekräfte und Scherkräfte gewährleistet.The invention is therefore based on the object to provide a frame made of metal for drainage channels, which can be integrated with the drainage channel, but ensures the absorption of high alternating tensile and compressive forces, bending forces and shear forces.

Diese Aufgabe wird bei einer eingangs genannten Zarge erfindungsgemäß dadurch gelöst, daß beide unteren Schenkel an der Unterseite mit mehreren Ausnehmungen versehen sind, die zwischen sich Vorsprünge stehen lassen und die Ausnehmungen und Vorsprünge eines unteren Schenkels zu denen des anderen unteren Schenkels jeweils zumindest teilweise und zumindest annähernd auf Lücke angeordnet sind.This object is achieved according to the invention in a frame mentioned at the outset in that both lower legs are provided on the underside with a plurality of recesses which allow projections to stand between them and the recesses and projections of a lower leg each at least partially and at least to those of the other lower leg are arranged approximately on gap.

Bei der erfindungsgemäßen Rinne schließen die äußeren Seiten der unteren Schenkel bündig mit den zugeordneten Seiten der Rinnenwände ab, und der zwischen den unteren Schenkeln gebildete Kanal ist mit dem Material des Rinnenkörpers, zum Beispiel Polyesterbeton, ausgefüllt. Insoweit geht die erfindungsgemäße Konstruktion jedoch nicht über den Stand der Technik hinaus. Erfindungswesentlich ist, daß die Unterseite der unteren Schenkel nicht gerade horizontal verläuft, sondern durch die eingeformten Ausnehmungen auf- und absteigend, wobei jeweils eine Ausnehmung eines unteren Schenkels einem Vorsprung des anderen unteren Schenkels gegenüberliegt. Die Übergänge zwischen Vorsprung und Ausnehmung sind vorzugsweise stetig, beispielsweise in Wellenform, um scharfe Angriffspunkte am Material des Rinnenkörpers zu vermeiden.In the gutter according to the invention, the outer sides of the lower legs are flush with the associated sides of the gutter walls, and the channel formed between the lower legs is filled with the material of the gutter body, for example polyester concrete. In this respect, however, the construction according to the invention does not go beyond the prior art. It is essential to the invention that the underside of the lower legs does not run exactly horizontally, but ascends and descends through the molded-in recesses, one recess of a lower leg opposite a projection of the other lower leg. The transitions between the projection and the recess are preferably continuous, for example in the form of waves, in order to avoid sharp points of attack on the material of the channel body.

Durch die erfindungsgemäße Ausgestaltung der Rinnenzarge wird eine optimale Einleitung der an der Zarge angreifenden horizontalen Kräfte in den Rinnenkörpergewährteistet, weit dersich den Kräften widersetzende Querschnitt der Rinnenwand vergrößert ist und keine glatte Bruchfläche entstehen kann, wie das bei der bekannten Verankerung der Rinnenzargen derfall ist.The inventive design of the channel frame ensures an optimal introduction of the horizontal forces acting on the frame into the channel body, to the extent that the cross-section of the channel wall that opposes the forces is enlarged and no smooth fracture surface can arise, as is the case with the known anchoring of the channel frames.

Nach einer Ausgestaltung der Erfindung ist vorgesehen, daß die Länge der Ausnehmungen annähernd dem Abstand der Vorsprünge ist. Auf diese Weise kann sichergestellt werden, daß Vorsprünge und Ausnehmungen gegenüberliegender unterer Schenkel genau auf Lücke angeordnet sind.According to one embodiment of the invention, it is provided that the length of the recesses is approximately the distance between the projections. In this way it can be ensured that projections and recesses of opposing lower legs are arranged exactly on the gap.

Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß die Schenkel im Bereich der Ausnehmungen und/oder der Vorsprünge Durchbrüche aufweisen. Das Rinnenmaterial, zum Beispiel Polyesterbeton, kann beim Formen der Rinne in die Durchbrüche eintreten und hier für eine besonders wirksame Verankerung der Zarge an der Rinnenwand sorgen.According to a further embodiment of the invention it is provided that the legs have openings in the area of the recesses and / or the projections. The gutter material, for example polyester concrete, can enter the openings when the gutter is being formed and ensure particularly effective anchoring of the frame on the gutter wall.

Es versteht sich, daß die Durchbrechungen im Bereich der Vorsprünge größer sein können als im Bereich der Ausnehmungen.It is understood that the openings in the area of the projections can be larger than in the area of the recesses.

In einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß die unteren Schenkel an den Enden im unteren Bereich Ausklinkungen aufweisen.In a further embodiment of the invention it is provided that the lower legs have notches at the ends in the lower region.

Eine andere Ausgestaltung der Erfindung sieht vor, daß der Auflagesteg in einem Endbereich einen Abschnitt größerer Dicke aufweist und in dem Abschnitt eine zur Innenseite der Rinne offene Verriegelungsausnehmung geformt ist. Die Verriegelungsausnehmung dient zur Aufnahme eines an der Abdeckung angebrachten schwenkbaren Riegels, der zum Beispiel mittels einer Schraube zur Fixierung der Abdeckung in die Ausnehmung eingeschwenkt werden kann.Another embodiment of the invention provides that the support web has a section of greater thickness in an end region and a locking recess open to the inside of the groove is formed in the section. The locking recess serves to receive a pivotable bolt attached to the cover, which can be pivoted into the recess, for example by means of a screw, to fix the cover.

Um die Kerbkräfte weiter herabzusetzen, sieht eine Ausgestaltung der Erfindung schließlich vor, daß alle dem Rinnenmaterial zugekehrten Kanten abgerundet sind.In order to further reduce the notch forces, an embodiment of the invention finally provides that all edges facing the channel material are rounded.

Eine aus Metall, beispielsweise Stahlguß gefertigte Zarge 10, hat die halbe Länge einer Entwässerungsrinne 11 (Fig. 7). Sie besitzt zwei nach unten weisende Schenkel 12,13, die parallel und im Abstand voneinander an einen Steg 14 angeformt sind. Der Steg weist eine Auflagefläche 15 für einen nicht gezeigten Rinnenrost auf. In gleicher Ebene wie der Schenkel 13 ist an der Oberseite des Steges 14 ein nach oben ragender Schenkel 16 angeformt, der dem Rinnenrost seitlichen Halt gibt.A frame 10 made of metal, for example cast steel, has half the length of a drainage channel 11 (FIG. 7). It has two legs 12, 13 pointing downwards, which are integrally formed on a web 14 in parallel and at a distance from one another. The web has a bearing surface 15 for a channel grate, not shown. In the same plane as the leg 13, an upwardly projecting leg 16 is formed on the top of the web 14, which gives lateral support to the channel grate.

Wie man aus Fig. 1 und 2 erkennt, weisen die Seitenwände 12,13 an den Enden und im unteren Bereich Ausklinkungen 17 auf. Sie sorgen bei einem Zusammenpassen benachbarter Entwässerungsrinnen mittels Nut-Federsystem für einen Freiraum. Bei einer Baulänge einer Entwässerungsrinne von 1000 mm können vier Zargen gleichen Typs verwendet werden. Damit wird die Bevorratung von Zargen vereinfacht (Einheitslänge). Im übrigen sind die Seitenwände 12, 13 so geformt, daß in Längsrichtung gesehen Vorsprünge 18 und Ausnehmungen 19 einander abwechseln, wobei der Übergang zwischen Vorsprung 18 und Ausnehmung 19 über eine wellenförmige Linie 20 stattfindet. In Fig. 1 ist der Verlauf der Unterseite des hinteren nach unten weisenden Schenkels 13 gestrichelt angedeutet, soweit er durch den Schenkel 12 verdeckt ist. Im Bereich der Ausnehmungen 19 sind Öffnungen oder Durchbrüche 21 eingeformt. Im Bereich der Vorsprünge 18 sind Öffnungen oder Durchbrüche 22 eingeformt, welche entsprechend der größeren Schenkelfläche eine größere Durchtrittsfläche bilden.As can be seen from FIGS. 1 and 2, the side walls 12, 13 have notches 17 at the ends and in the lower region. They ensure free space when adjacent drainage channels fit together using a tongue and groove system. With a length of a drainage channel of 1000 mm, four frames of the same type can be used. This simplifies the stocking of frames (unit length). Otherwise, the side walls 12, 13 are shaped such that projections 18 and recesses 19 alternate with one another when viewed in the longitudinal direction, the transition between projection 18 and recess 19 taking place via a wavy line 20. In Fi g. 1, the course of the underside of the rear leg 13 pointing downward is indicated by dashed lines, insofar as it is covered by the leg 12. Openings or openings 21 are formed in the area of the recesses 19. Openings or openings 22 are formed in the area of the projections 18 and form a larger passage area in accordance with the larger leg area.

Wie man aus Fig. 1 entnimmt, weist der Steg 14 an den Enden Einsenkungen 23 auf, die in einem verstärkten Abschnitt des Steges 14 geformt sind und entsprechend geformte Vorsprünge des Rinnenrostes aufnehmen, um diesen gegen Längsverschiebung zu sichere, Im Bereich der Einsenkung 23 am rechten Ende in Fig. 1 weist der Schenkel 12 eine Durchbrechung 24 auf. Im linken Bereich ist der Steg 14 als Abschnitt größerer Dicke gebildet. Auf der dem oberen Schenkel 16 abgekehrten Seite ist seitlich in diesen Abschnitt eine längliche horizontale Ausnehmung 25 angeformt (siehe Fig. 1, 3 und 6). Mit einer Rinnenwand verbunden weist die Ausnehmung 25 zum Inneren der Rinne hin. Sie dient zur Aufnahme eines schwenkbaren Riegels der nicht gezeigten Rinnenabdeckung. Zur gegenüberliegenden Seite der Zarge 10 ist die Ausnehmung über eine Gewindebohrung 26 verbunden. Sie dient zur Aufnahme einer Gewindeschraube, mit der ein Betonanker verbindbar ist. Auf diese Weise können Zarge und Rinnenkörper beim Einbau im Ortbeton zusätzlich verankert werden.As can be seen from FIG. 1, the web 14 has depressions 23 at the ends, which are formed in a reinforced section of the web 14 and receive correspondingly shaped projections of the channel grate in order to secure them against longitudinal displacement, in the region of the depression 23 am Right end in Fig. 1, the leg 12 has an opening 24. In the left area, the web 14 is formed as a section of greater thickness. On the side facing away from the upper leg 16, an elongated horizontal recess 25 is formed laterally in this section (see FIGS. 1, 3 and 6). Connected to a channel wall, the recess 25 points toward the interior of the channel. It serves to accommodate a pivotable bolt of the channel cover, not shown. The recess is connected to the opposite side of the frame 10 via a threaded bore 26. It is used to hold a threaded screw with which a concrete anchor can be connected. In this way, the frame and channel body can be additionally anchored when installed in in-situ concrete.

Aus Fig. 7 ist zu ersehen, wie die Zarge 10 mit den Wänden 26a, 27 eines aus Polyesterbeton bestehenden Rinnenkörpers 11 integriert ist. Man erkennt, daß die Außenseiten der unteren Schenkel 12, 13 und des oberen Schenkels 16 bündig mit den zugekehrten Seiten der Wände 26a, 27 abschließen. Man erkennt ferner, daß das Rinnenmaterial in den zwischen den unteren Schenkeln 12, 13 gebildeten Kanal eingeformt ist und auch in die Durchbrüche 21, 22 eingetreten ist. Aus Fig. 7 wird auch die hinsichtlich der Kraftaufnahme besonders vorteilhafte Verankerung der Zarge 10 deutlich.From Fig. 7 it can be seen how the frame 10 is integrated with the walls 26a, 27 of a channel body 11 made of polyester concrete. It can be seen that the outer sides of the lower legs 12, 13 and the upper leg 16 are flush with the facing sides of the walls 26a, 27. It can also be seen that the channel material is molded into the channel formed between the lower legs 12, 13 and has also entered the openings 21, 22. FIG. 7 also shows the anchoring of the frame 10 which is particularly advantageous with regard to the force absorption.

Insbesondere aus den Fig. 4 bis 7 ist deutlich erkennbar, daß die Zarge 10 an allen Kanten, die dem Rinnenmaterial zugekehrt sind, ausgeprägte Abrundungen aufweist.In particular from FIGS. 4 to 7 it can be clearly seen that the frame 10 has pronounced roundings on all edges which face the channel material.
