Abstract

The drainage channel exhibits gratings which can be fastened on the channel body without additional fastening means. The channel body (2) exhibits, on its longitudinal sides (15, 16), in each case one guidance and bearing surface (17, 18) for the gratings (1, 1a, 1b) and the latter exhibit, on their two longitudinal sides (9, 10), in each case one bearing surface (13) which corresponds to the guidance and bearing surface (17, 18) on the channel body (2). On one longitudinal side (9) there are arranged, beneath the bearing surface (13), outwardly directed hooks (11) which engage in cutouts (19) arranged beneath the bearing surface (18) on the channel body. Such channel bodies and gratings can be produced cost-effectively and with conventional manufacturing tolerances and permit reliable fastening of the gratings, even in the case of heavy loading. <IMAGE>

Description

Die vorliegende Erfindung bezieht sich auf eine Entwässerungsrinne mit mindestens zwei Abdeckroste gemäss Oberbegriff von Patentanspruch 1. Solche Entwässerungsrinnen mit Abdeckroste, die ohne Schrauben befestigbar sind, sind aus der EP-B-0 204 278 bekannt. Dabei greifen die Abdeckroste schwalbenschwanzförmig mit ihren spitz- bzw. stumpfwinkligen Führungsflächen an den Längsseiten in entsprechend geformte Führungsflächen im Rinnenkörper. Diese schraubenlose Befestigungsart bedingt recht enge Fertigungstoleranzen, die nicht immer erfüllt werden können und daher nur mit Gummieinlagen ausgeglichen werden können.The present invention relates to a drainage channel with at least two cover gratings according to the preamble of claim 1. Such drainage channels with cover gratings which can be fastened without screws are known from EP-B-0 204 278. The cover grids dovetail-shaped with their acute or obtuse-angled guide surfaces on the long sides engage in correspondingly shaped guide surfaces in the channel body. This type of screwless fastening requires very tight manufacturing tolerances, which cannot always be met and can therefore only be compensated for with rubber inserts.

Auch andere bekannte Entwässerungsrinnen für grosse Belastungen mit schraubenlos befestigbaren Abdeckroste bedingen enge Fertigungstoleranzen, die oft nicht erfüllt werden können.Other known drainage channels for large loads with screwless cover grids also require tight manufacturing tolerances, which often cannot be met.

Es ist davon ausgehend Aufgabe der vorliegenden Erfindung, eine Entwässerungsrinne mit Abdeckroste anzugeben, bei welcher die Abdeckroste sicher ohne Schrauben und dergleichen befestigt werden können und der Rinnenkörper und die Abdeckroste ohne besonderen Fertigungstoleranzen und Aufwand hergestellt werden können. Diese Aufgabe wird mit einer Entwässerungsrinne mit Abdeckroste gemäss Patentanspruch 1 gelöst.It is based on the object of the present invention to provide a drainage channel with cover grids, in which the cover grids can be securely attached without screws and the like and the channel body and the cover grates can be manufactured without special manufacturing tolerances and effort. This object is achieved with a drainage channel with grating according to claim 1.

Die Erfindung wird im Folgenden anhand einer Zeichnung eines Ausführungsbeispiels näher erläutert.The invention is explained in more detail below with reference to a drawing of an exemplary embodiment.

  • Fig. 1 zeigt einen Teil eines Rinnenkörpers mit aufgesetztem Abdeckrost in Draufsicht,1 shows a top view of part of a channel body with a cover grating attached,
  • Fig. 2 zeigt eine Seitenansicht des Abdeckrostes undFig. 2 shows a side view of the grating and
  • Fig. 3 zeigt, im vergrösserten Masstab, einen Schnitt gemäss der Linie 111-111 in Fig. 1.FIG. 3 shows, on an enlarged scale, a section along the line 111-111 in FIG. 1.

In Figur 1 erkennt man Abdeckroste 1, 1 und 1 b, die im Rinnenkörper 2 eingelegt sind. Die Abdeckroste weisen übliche längliche Queröffnungen 3 sowie Noppen 4 und auf der anderen Seite Verstärkungsrippen 23 auf. Im vorliegenden Fall handelt es sich um Gussroste, während die Rinnenkörper aus Polymerbeton oder Beton hergestellt sind.In Figure 1 you can see cover gratings 1, 1 and 1 b, which are inserted in the channel body 2. The cover gratings have the usual elongated transverse openings 3 and knobs 4 and reinforcing ribs 23 on the other side. In the present case, the grates are cast, while the channel bodies are made of polymer concrete or concrete.

Aus den Figuren 1 und 2 geht hervor, dass die Querseiten 5 bzw. 6 des Abedeckrostes 2 je einen zueinander komplementär ausgebildeten Absatz 7 bzw. 8 aufweisen, wobei an jeder Längsseite des Rostes 9 bzw. 10 stets die gleichartigen Absätze angeordnet sind. Das heisst, dass auf der einen Längsseite, z. B. 9, die beiden Absätze 7 angeordnet sind, die von oben gesehen als Vorsprünge ausgebildet sind, während die anderen beiden Absätze 8 an der Längsseite 10 von oben gesehen als Ausnehmungen erscheinen.It can be seen from FIGS. 1 and 2 that the transverse sides 5 and 6 of the covering grate 2 each have a step 7 or 8 which is designed to be complementary to one another, the similar steps being always arranged on each long side of the grate 9 and 10. That means that on one long side, e.g. B. 9, the two paragraphs 7 are arranged, which are formed as projections seen from above, while the other two paragraphs 8 appear on the longitudinal side 10 seen from above as recesses.

An der Längsseite 9 mit den beiden als Vorsprüngen ausgebildeten Absätzen 7 sind zwei nach aussen weisende Haken 11 angeordnet, deren untere Schenkel 12 in einem Abstand von der Auflagefläche 13 des Abdeckrostes angeordnet sind. Die andere Längsseite 10 des Abdeckrostes besitzt ebenfalls eine Auflagefläche 14.On the long side 9 with the two shoulders 7 designed as projections, two outwardly pointing hooks 11 are arranged, the lower legs 12 of which are arranged at a distance from the contact surface 13 of the cover grate. The other long side 10 of the grating also has a support surface 14.

Der Rinnenkörper 2, aus Polymerbeton oder Beton, weist einen U-förmigen Querschnitt auf, mit Seitenwänden 15 und 16, an denen oben je eine Stufe mit je einer Führungsfläche 17 und einer Auflagefläche 18 angeordnet ist, in die der Rost eingesetzt ist. Zum Schutze der oberen Kanten können an den Längsseiten Abdeckungen 20 aus Metall im Rinnenkörper eingelassen sein. Unterhalb der Auflagefläche 18 befindet sich eine Aussparung 19, in die gemäss Figur 3 die Haken 11 des Rostes greifen können. Die Aussparungen können mit einer entsprechenden Kunststoffeinlage 21 versehen sein. Die übrige Ausgestaltung des Rinnenkörpers ist an sich bekannt, insbesondere die Ausnehmungen 22 an den Längsaussenseiten.The channel body 2, made of polymer concrete or concrete, has a U-shaped cross section, with side walls 15 and 16, on each of which a step with a guide surface 17 and a support surface 18 is arranged, in which the grate is inserted. To protect the upper edges, metal covers 20 can be embedded in the channel body on the long sides. Below the support surface 18 there is a recess 19 into which the hooks 11 of the grate can engage according to FIG. 3. The cutouts can be provided with a corresponding plastic insert 21. The rest of the design of the channel body is known per se, in particular the recesses 22 on the longitudinal outer sides.

Das einfache Einlegen und die Verankerung des Abdeckrostes in der Entwässerungsrinne gehen aus Figur 1 hervor. Bezüglich der dort gezeigten beiden Abdeckroste 1 und 1 ist ersichtlich, dass diese abwechslungsweise so verlegt werden, dass die Haken 11 einmal in die linke und dann in die rechte Aussparung des Rinnenkörpers greifen. Da die unten liegenden, eine Ausnehmung bildenden Absätze 8 jeweils an den den Haken entgegengesetzten Längsseiten angebracht sind und auf diese Absätze die die Vorsprünge bildenden Absätze 7 zu liegen kommen, die zudem durch die Haken gesichert sind, können die Abdeckroste nicht durch Fahrzeuge aufgehoben und unabsichtlich entfernt werden.The simple insertion and anchoring of the cover grate in the drainage channel are shown in FIG. 1. With regard to the two cover grids 1 and 1 shown there, it can be seen that these are alternately laid in such a way that the hooks 11 engage once in the left-hand and then in the right-hand recess of the channel body. Since the lower, recesses forming paragraphs 8 are each attached to the long sides opposite the hooks and on these heels the projections 7 forming the projections come to rest, which are also secured by the hooks, the cover grids cannot be lifted by vehicles and unintentionally be removed.

Die Abdeckroste werden von einem Ende des Rinnenkörpers her nacheinander und jeweils um 180 ° versetzt auf dessen Auflagefläche aufgesetzt, wobei die Haken jeweils in Eingriff mit einer Aussparung im Rinnenkörper gebracht werden und die Roste dicht aneinanderliegend zum anderen Ende geschoben werden. Dann wird der letzte Rost eingeschoben, der mit einem Sicherungsbügel vor dem Herausheben gesichert wird. Das Herausnehmen ist dann nur möglich, falls dieser Sicherungsbügel entfernt wird um den ersten Rost heraus zu nehmen, woraufhin die anderen Roste um die Länge der Absätze verschoben und herausgehoben werden können.The cover grids are placed one after the other and each offset by 180 ° on the support surface, the hooks are brought into engagement with a recess in the channel body and the grids are pushed close to each other to the other end. Then the last grate is inserted, which is secured with a safety bracket before lifting out. Removal is only possible if this safety bracket is removed to take out the first grate, whereupon the other grids can be moved and lifted out by the length of the shoulders.

Die Verwendung von Haken und Absätzen am Abdeckrost und von Aussparungen am Rinnenkörper ermöglicht eine einfache Fertigung dieser Teile mit den bei solchen Artikeln üblichen Toleranzen und bewirkt einen sehr guten Schutz vor dem Herausheben bei schwerer Beanspruchung.The use of hooks and shoulders on the cover grille and recesses on the channel body enables these parts to be easily manufactured with the tolerances customary for such articles and provides very good protection against being lifted out under heavy loads.
