Description
Aus der CH-A-588 597 ist eine Entwässerungsrinne aus Rinnenelementen aus verzinktem Stahlblech bekannt. Sie hat einen V-förmigen Boden, daran anschliessende, vertikale, ebene Seitenwände, die oben L-förmig abgeköpft sind unter Bildung einer horizontalen Schulter zur Auflage eines Rostes und eines an die Schulter anschliessenden senkrechten Randes. Zwei aneinandergrenzende Elemente werden über einen Kupplungsbügel und Querlaschen miteinander verbunden. Die Querlaschen durchgreifen Schlitze in den Seitenwänden und im Kupplungsbügel. Diese Rinne ist im umgebenden Beton nicht hinreichend verankert. Die Querlaschen erschweren die Reinigung.From CH-A-588 597 is a drainage channel made of channel elements known from galvanized sheet steel. It has a V-shaped Floor, adjoining, vertical, flat side walls, the top L-shaped are skimmed to form a horizontal Shoulder to rest a grate and one to the Vertical edge adjoining the shoulder. Two contiguous Elements are attached via a coupling bracket and cross brackets connected with each other. Reach through the cross straps Slits in the side walls and in the coupling bracket. This gutter is not sufficiently anchored in the surrounding concrete. The cross brackets make cleaning difficult.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Entwässerungsrinne der eingangs genannten Art derart auszubilden, dass sie im Beton formschlüssig verankert ist. Diese Aufgabe wird durch die Merkmalskombination der Ansprüche gelöst.The present invention has for its object a To design drainage channels of the type mentioned at the beginning, that it is positively anchored in the concrete. This task is solved by the combination of features of the claims.
Die Ausbildung der Rinne gemäss Anspruch 1 ermöglicht den hygienisch einwandfreien Betrieb sowie Reinigung und eine rationelle Herstellung durch einfaches Abkanten. Der Umstand, dass die Rinne unten breiter ist als im oberen Bereich der Seitenwände, hat eine Reihe von Vorteilen:
- beim Eingiessen in Beton ist die Rinne zuverlässig im Beton formschlüssig und mechanisch verankert, ohne dass zusätzliche Verankerungselemente angebracht werden müssen.
- Die vom Rost auf die Schultern übertragenen Kräfte werden direkt in den Beton eingeleitet, so dass die Rinne dünnwandig ausgebildet werden kann. Dadurch sind die Herstellungs- und Transportkosten niedrig.
- Die Herstellung durch einfaches Abkanten ist sehr rationell.
- Die Rinne ist stapelbar, was besonders den Transport und die Lagerung vereinfacht.
- Beim Ausspritzen der Rinne mit einem Schlauch spritzt weniger Wasser aus der Rinne zurück.
- Die Weiterbildung gemäss
Anspruch 3 hat den besonderen Vorteil, dass aneinander anschliessende Rinnen sehr einfach formschlüssig ineinandergesteckt werden können und dann automatisch sowohl in der Höhe als auch quer exakt fluchten.
- when pouring into concrete, the channel is reliably positively and mechanically anchored in the concrete without the need for additional anchoring elements.
- The forces transmitted from the grate to the shoulders are introduced directly into the concrete so that the channel can be made thin-walled. As a result, the manufacturing and transport costs are low.
- The production by simple folding is very efficient.
- The gutter is stackable, which particularly simplifies transport and storage.
- When spraying the gutter with a hose, less water splashes back out of the gutter.
- The further development according to
claim 3 has the particular advantage that adjoining gutters can be plugged into one another in a form-fitting manner and then automatically aligned exactly both vertically and transversely.
Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand
der Zeichnung erläutert. Darin zeigt:
Die dargestellte Rinne 1 besteht aus abgekantetem, nichtrostendem
Stahlblech. Sie hat einen ebenen Boden 2 und zwei
mit dem Boden 2 den gleichen, spitzen Winkel 3 bildende,
ebene Seitenwände 4. An die Seitenwände 4 schliesst oben je
eine parallel zum Boden 2 verlaufende, nach aussen abgekröpfte,
ebene Schulter 5 zur Auflage eines Rostes an. Aussen
schliessen an den Schultern 5 senkrecht nach oben ragende
Ränder 6 an, die zur Verstärkung und zur Vermeidung
scharfer Kanten einen um 180° abgekröpften Bördelrand 7 haben.
Am einen Stirnende ist ein den Boden 2 und die Seitenwände
4 umgreifendes, stirnseitig Boden und Seitenwände
überragendes Blech 8 durch Schweisspunkte 9 befestigt. Es
dient zur formschlüssigen Aufnahme des anderen Endes einer
weiteren Rinne 1. Alternativ könnte das Blech 8 auch nur
mit etwas Vorspannung übergeschoben sein.The gutter 1 shown consists of folded, rustproof
Sheet steel. It has a
Die Aussenabmessung 15 der Rinne 1 im Bereich des Bodens 2
ist etwas kleiner als die lichte Weite 16 zwischen den Rändern
6 aber grösser als die lichte Weite 17 am oberen Ende
der Seitenwände 4. Dadurch ist die Rinne stapelbar.
Zugleich wird damit eine formschlüssige Verankerung im Beton,
in welchen die Rinne 1 eingegossen wird, erreicht.The
Zweckmässig werden mehrere Rinnen 1 mit unterschiedlicher
Höhe 18 der Seitenwände 4 aber sonst gleichen Abmessungen
15, 16, 17 bereitgestellt, um das Niveau des Abflusses den
örtlichen Gegebenheiten anpassen zu können und trotzdem die
Stapelbarkeit auch unterschiedlich hoher Rinnen beizubehalten.
Der Winkel 3 ist dabei je nach Höhe 18 unterschiedlich.
Selbstverständlich können auch unterschiedlich breite
Rinnen 1 angeboten werden, wobei auch dort wieder verschieden
hohe Rinnen aber mit gleichen Breiten ineinander gestapelt
werden können.Several channels 1 with different are
Je nach Anwendungsfall kommt als Material für die Rinne 1 auch verzinktes Stahlblech oder faserverstärktes Kunstharz in Frage.Depending on the application, the material for the channel 1 also galvanized sheet steel or fiber-reinforced synthetic resin in question.
Zweckmässig werden nebst den Rinnen 1 zusätzlich Auslaufstücke, z.B. mit seitlichem Auslauf und solche mit Auslauf in ein Rohr nach unten mit einer Biegung nach mehreren Seiten angeboten. Solche Auslaufstücke haben zweckmässig einseitig eine Abschlusswand. Zudem sind Anfangselemente erforderlich, die ebenfalls einseitig abgeschlossen sind.In addition to the channels 1, there are also additional outlet pieces, e.g. with side outlet and those with outlet into a tube down with a bend to several sides offered. Such outlet pieces are expediently one-sided an end wall. In addition, initial elements are required which are also closed on one side.
