Description
Die Erfindung betrifft eine Wasserablaufeinrichtung für einen oben offenen und unten durch einen Boden verschlossenen Schacht, insbesondere einen an einem Gebäude anbringbaren Lichtschacht, mit einem bodenseitig vorgesehenen Ablaufkanal.The invention relates to a water drainage device for a shaft that is open at the top and closed at the bottom by a floor, in particular a light shaft that can be attached to a building, with a drainage channel provided on the floor.
Bei gebräuchlichen Lichtschächten ist zur Bildung einer Wasserablaufeinrichtung häufig lediglich ein bodenseitiges Loch vorgesehen. Hierbei erweist sich jedoch eine zuverlässige Ableitung von in den Schacht gelangendem Wasser als vergleichsweise schwierig.In the case of conventional light wells, often only one hole in the bottom is provided to form a water drainage device. In this case, however, reliable drainage of water entering the shaft proves to be comparatively difficult.
Es ist daher die Aufgabe der vorliegenden Erfindung, eine Anordnung eingangs erwähnter Art zu schaffen, die eine zuverlässige Entwässerung eines Schachts gewährleistet.It is therefore the object of the present invention to create an arrangement of the type mentioned at the outset that ensures reliable drainage of a shaft.
Zur Lösung dieser Aufgabe ist ein den Ablaufkanal enthaltendes, in den Boden des Schachts einbaubares Ablaufrohr vorgesehen, das an seinem oberen, eingangsseitigen Ende eine Sitzanordnung für einen lösbar anbringbaren, mit einer Siebanordnung versehenen Deckel aufweist und das im Bereich seiner Innenseite mit einem nach radial innen vorspringenden Anschlag für eine von unten einschiebbare Drainageleitung und an seiner Außenseite mit einer nach radial außen abstehenden, umlaufenden Kriechwassersperre versehen ist.To solve this problem, a drain pipe is provided that contains the drain channel and can be built into the bottom of the shaft, which has a seat arrangement for a detachably attachable cover provided with a sieve arrangement at its upper, input-side end and which in the region of its inside with a radially inward protruding stop for a drainage line that can be inserted from below and is provided on its outside with a radially outwardly projecting, circumferential anti-leakage barrier.
Das erfindungsgemäße Ablaufrohr ermöglicht einen einfach herstellbaren, zuverlässigen Anschluss der von unten einsteckbaren, zu einer Kanalisation etc. führenden Drainageleitung. Der dieser zugeordnete Anschlag stellt sicher, dass die von unten einsteckbare Drainageleitung auch bei einer Blindmontage auf der Baustelle bis auf Anschlag und damit mit der gewünschten Länge zuverlässig zum Eingriff in das Ablaufrohr gebracht werden kann. Die dem abnehmbaren Deckel zugeordnete Siebanordnung stellt sicher, dass zwar Wasser abfließen kann, unerwünschte Verunreinigungen jedoch zurückgehalten werden, so dass einer Rohrverstopfung sowie einer Versandung und/oder Verschlammung einer angeschlossenen Kanalisation oder Sickergrube etc. wirksam vorgebeugt ist. Infolge der Abnehmbarkeit des Deckels ist nicht nur eine einfache Reinigung der Siebanordnung möglich, sondern ergibt sich auch eine gute Zugänglichkeit zur Innenseite des Ablaufrohrs und der hieran anschließenden Drainageleitung für Wartungszwecke etc.. Die von der Außenseite des Ablaufrohrs abstehende Kriechwassersperre, die einfach als umlaufender Flansch ausgebildet sein kann, verhindert in vorteilhafter Weise, dass von unten anstehendes Druckwasser zurückgehalten wird und nicht am Ablaufrohr vorbei in das Schachtinnere gelangen kann.The drain pipe according to the invention enables a simple to manufacture, reliable connection of the drainage line that can be inserted from below and leads to a sewage system. The stop associated with this ensures that the drainage line, which can be inserted from below, can be reliably engaged in with a blind installation on the construction site up to the stop and thus with the desired length the drain pipe can be brought. The sieve arrangement assigned to the removable cover ensures that although water can drain off, unwanted impurities are retained, so that a pipe blockage and silting up and/or silting up in a connected sewage system or septic tank etc. is effectively prevented. As the cover can be removed, not only is the sieve arrangement easy to clean, but there is also good access to the inside of the drain pipe and the drainage line connected to it for maintenance purposes, etc. can be formed, prevents in an advantageous manner that pending pressurized water is retained from below and can not get past the drain pipe into the shaft interior.
Vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den Unteransprüchen angegeben.Advantageous refinements and expedient developments of the higher-level measures are specified in the dependent claims.
So kann zweckmäßig eine mehrstufige Siebanordnung mit einem eingangsseitigen Grobsieb und wenigstens einem diesem nachgeordneten Feinsieb vorgesehen sein. Hierdurch ergibt sich eine hohe Abscheidewirkung, indem nicht nur größere Fremdkörper, wie Laub etc., zurückgehalten werden, sondern auch feinere Verunreinigungen wie Sand etc..A multi-stage screen arrangement with a coarse screen on the inlet side and at least one fine screen arranged downstream of this can be expediently provided. This results in a high separation effect, in that not only larger foreign bodies, such as leaves, etc., are retained, but also finer impurities such as sand, etc..
Eine weitere zweckmäßige Maßnahme kann darin bestehen, dass das Ablaufrohr im Bereich des dem Deckel zugeordneten Sitzes mit einer umlaufenden, einem deckelseitigen Eingriffsstutzen zugeordneten Dichtung und unterhalb hiervon mit einer nach radial innen vorspringenden, vorzugsweise als umlaufende Rippe ausgebildeten Anschlagelement versehen ist, dessen Oberseite als Anschlag für den deckelseitigen Eingriffsstutzen und dessen Unterseite den der Drainageleitung zugeordneten Anschlag bildet. Infolge dieser Doppelwirkung des Anschlagelements kommt man mit einem Anschlagelement aus, was die Herstellung erleichtert.A further expedient measure can be that the drain pipe is provided in the area of the seat assigned to the cover with a circumferential seal assigned to a cover-side engagement socket and below this with a stop element projecting radially inwards, preferably designed as a circumferential rib, the upper side of which acts as a stop forms the stop associated with the drainage line for the access socket on the cover and the underside of which. As a result of this double action of the stop element, one stop element is sufficient, which simplifies production.
Vorteilhaft kann der genannte Deckel drehbar und mittels eines Bajonettverschlusses gegen Abheben gesichert sein. Hierdurch ergibt sich eine einfache Abnehmbarkeit und dennoch ein zuverlässiger Halt des Deckels. Zur Vereinfachung der Manipulation des Deckels kann dieser vorteilhaft mit einem Eingriffselement zum Ansetzen eines geeigneten Werkzeugs versehen sein.Advantageously, said cover can be rotated and secured against being lifted off by means of a bayonet lock. This results in easy detachability and still a reliable hold of the lid. In order to simplify the manipulation of the cover, it can advantageously be provided with an engagement element for attaching a suitable tool.
Gemäß einer weiteren vorteilhaften Ausgestaltung der übergeordneten Maßnahmen kann eine der eingangsseitigen Siebanordnung nachgeordnete Siphonanordnung vorgesehen sein, die zweckmäßig ein trichterförmiges Durchlasselement mit einer oberen Einlassöffnung und einer unteren Auslassöffnung aufweist, welcher eine umlaufende Dichtung und eine durch eine an ihr angreifende Schließkraft in ihrer an der Dichtung anliegenden Schließstellung haltbare und durch eine vom ankommenden Wasser ausgeübte Kraft entgegen der Wirkung der Schließkraft in Öffnungsrichtung bewegbare Verschlussklappe zugeordnet ist. Die Siphonanordnung ergibt in vorteilhafter Weise eine zuverlässige Geruchssperre, so dass aus einer Kanalisation etc. aufsteigende Gerüche zurückgehalten werden. Die durch das ankommende Wasser entgegen einer vorgesehenen Schließkraft betätigbare Verschlussklappe ergibt in vorteilhafter Weise eine automatische Funktionsweise.According to a further advantageous embodiment of the higher-level measures, a siphon arrangement can be provided downstream of the sieve arrangement on the inlet side, which expediently has a funnel-shaped passage element with an upper inlet opening and a lower outlet opening, which has a peripheral seal and a closing force acting on it in its on the seal adjacent closed position is assigned durable and by a force exerted by the incoming water force against the action of the closing force in the opening direction movable closure flap. The siphon arrangement advantageously results in a reliable odor barrier, so that odors rising from a sewage system, etc., are held back. The closing flap, which can be actuated by the incoming water against an intended closing force, advantageously results in an automatic mode of operation.
In weiterer Fortbildung dieser Maßnahmen kann die Siphonanordnung vorteilhaft in den Deckel eingebaut sein. Hierdurch wird sichergestellt, dass die Siphonanordnung für Inspektionszwecke etc. leicht vom Ablaufrohr abnehmbar ist.In a further development of these measures, the siphon arrangement can advantageously be built into the cover. This ensures that the siphon assembly can be easily removed from the drain pipe for inspection etc.
Eine weitere vorteilhafte Maßnahme kann darin bestehen, dass die der Auslassöffnung der Siphonanordnung zugeordnete Verschlussklappe als Wanne ausgebildet ist, die im Bereich ihres Rands um eine horizontale Achse schwenkbar gelagert ist und der eine die Schließkraft erzeugende Einrichtung zugeordnet ist. In der die Verschlussklappe bildenden Wanne kann sich nach und nach so viel Wasser sammeln, dass dessen Gewicht ausreicht, um die Verschlussklappe entgegen der Wirkung der hieran angreifenden Schließkraft zu öffnen. Hierdurch ist auch bei einem geringeren Wasseranfall eine zuverlässige Funktionsweise gewährleistet.
Zur Erzeugung der Schließkraft kann einfach ein mit der Verschlussklappe in Form einer zweiarmigen Wippe zusammenwirkendes Gegengewicht vorgesehen sein. Dies ergibt in vorteilhafter Weise eine teilearme, wartungsfreie Anordnung.A further advantageous measure can consist in the closure flap associated with the outlet opening of the siphon arrangement being designed as a trough which is pivotably mounted about a horizontal axis in the region of its edge and to which a device generating the closing force is allocated. In the trough forming the closure flap, so much water can gradually collect that its weight is sufficient to open the closure flap against the effect of the closing force acting on it. This ensures reliable functioning even with less water accumulation.
To generate the closing force, a counterweight that interacts with the closing flap in the form of a two-armed rocker can simply be provided. This advantageously results in a low-parts, maintenance-free arrangement.
Eine weitere zweckmäßige Maßnahme kann darin bestehen, dass das Ablaufrohr oder/und der Deckel als aus Kunststoff hergestellte Formlinge, zweckmäßig als Kunststoff-Spritzgussformlinge, ausgebildet sind. Um dabei für verschiedene Schachtbodendicken mit einem Formteil auszukommen, kann einfach vorgesehen sein, dass das Ablaufrohr mit einer einer maximalen Bodendicke entsprechenden Länge hergestellt wird und mit Abstand vom unteren Ende mit wenigstens einer, vorzugsweise mehreren, in der Höhe gegeneinander gestaffelten, verschiedenen gängigen Bodendicken zugeordneten Ablängmarkierungen versehen ist.A further expedient measure can be that the drain pipe and/or the cover are designed as moldings made of plastic, expediently as plastic injection moldings. In order to get by with one molded part for different shaft base thicknesses, it can simply be provided that the discharge pipe is produced with a length corresponding to a maximum base thickness and is assigned at a distance from the lower end with at least one, preferably several, different common base thicknesses staggered in height cutting marks is provided.

Die so ausgebildete Verschlussklappe 22 ist im Bereich ihres Rands um eine horizontale Achse schwenkbar an einem an das Durchlassteil 21 angesetzten Lagerbock 23 gelagert. Durch das Gewicht des in dem die Verschlussklappe 22 bildenden Gefäß gesammelten Wassers wird die schwenkbar gelagerte Verschlussklappe 22 entgegen einer ihr zugeordneten Schließkraft geöffnet. Zur Erzeugung der Schließkraft kann ein mit der Verschlussklappe 22 zusammenwirkendes Gegengewicht 24 vorgesehen sein, das zusammen mit der Verschlussklappe 22 praktisch eine zweiarmige Wippe bildet, die so austariert ist, dass die Verschlussklappe 22 öffnet, sobald sich im die Verschlussklappe 22 bildenden Auffanggefäß eine gewünschte Wassermenge angesammelt hat. Es wäre aber auch denkbar, zur Erzeugung der Schließkraft eine mit der Verschlussklappe 22 zusammenwirkende Schließfeder vorzusehen, beispielsweise in Form einer in die Schwenklagerung integrierten Torsionsfeder.The
Vorstehend ist zwar ein besonders bevorzugtes Ausführungsbeispiel der Erfindung näher erläutert, ohne dass jedoch hiermit eine Beschränkung verbunden sein soll. So wäre es beispielsweise auch denkbar, die Kriechwassersperre 9 nicht an das Auslaufrohr 3 anzuformen, sondern anzusetzen. Ebenso wäre es denkbar, den Deckel 10 mittels eines Schraubgewindes im Ablaufrohr 3 festzulegen und dergleichen.Although a particularly preferred exemplary embodiment of the invention has been explained in more detail above, this is not intended to be associated with a restriction. It would also be conceivable, for example, not to form the
