Description

Die Erfindung betrifft eine Anschlussvorrichtung für ein Ablaufsystem zur Entwässerung von Verkehrsflächen, wobei die Anschlussvorrichtung einen Aufsatzstutzen, der mit einem Aufsatz zum Ableiten von Wasser verbindbar ist, und einen Ablaufkörper aufweist, der mit einem Abwassersystem verbindbar ist.The invention relates to a connection device for a drainage system for draining traffic areas, the connection device having an attachment socket which can be connected to an attachment for draining water, and a drainage body which can be connected to a sewage system.

Eine Anschlussvorrichtung dieser Gattung wird beispielsweise in der Praxis bei der Entwässerung von Brücken angewandt.A connection device of this type is used in practice, for example, to drain bridges.

Bei einer solchen Anschlussvorrichtung besteht das Verbindungsstück zwischen Aufsatz und Ablaufkörper aus einem einfachen Rohr. Dieses wird mittels einer Steckverbindung mit dem Aufsatz verbunden und zusammen mit diesem auf ein um den Ablaufkörper aufgetragenes Mörtelbett gesetzt.With such a connection device, the connecting piece between the attachment and the drain body consists of a simple tube. This is connected to the attachment using a plug-in connection and placed together with it on a bed of mortar applied around the drain body.

Dies hat den Nachteil, dass beim Verlegen des Aufsatzes Mörtel in den Ablaufkörper gelangen kann. Gleichzeitig muss aber ausreichend Masse aufgetragen werden, um spätere Hohlstellen zu vermeiden. Andernfalls besteht die Möglichkeit, dass der verlegte Aufsatz den Belastungen einer befahrenen Verkehrsfläche nicht standhält.This has the disadvantage that mortar can get into the drain body when laying the attachment. At the same time, however, sufficient mass must be applied to avoid hollow spots later. Otherwise there is a possibility that the installed attachment will not be able to withstand the loads of a busy traffic area.

Aus DE 203 19 696 ist bekannt, dass zum Schutz vor unerwünschten Baustoffen im Ablaufkörper die Öffnung des Ablaufkörpers mit Hilfe einer Bauschutzabdeckung während des Erhärtens verschlossen wird. Diese Abdeckung wird nach dem Aushärten des Baustoffs zerstört und entfernt. Diese Methode ist umständlich und zeitaufwändig.Out of DE 203 19 696 It is known that to protect against unwanted building materials in the drain body, the opening of the drain body is closed with the help of a protective cover during hardening. This cover is destroyed and removed after the building material has hardened. This method is cumbersome and time-consuming.

Aus DE 296 14 144 U ist eine gattungsgemäße Anschlußvorrichtung gemäß dem Oberbegriff des Anspruchs 1 bekannt.Out of DE 296 14 144 U a generic connection device according to the preamble of claim 1 is known.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Anschlussvorrichtung der eingangs genannten Art so zu verbessern, dass eine Montage des Aufsatzes mit Aufsatzstutzen auf den Ablaufkörper derart möglich ist, dass dieser weitestgehend frei von Verschmutzungen bleibt.The invention is therefore based on the object of improving a connection device of the type mentioned in such a way that it is possible to mount the attachment with attachment socket on the drain body in such a way that it remains largely free of contamination.

Diese Aufgabe wird erfindungsgemäß durch eine Anschlussvorrichtung mit den Merkmalen aus Anspruch 1 gelöst.This object is achieved according to the invention by a connection device with the features of claim 1.

Konkret wird die Aufgabe durch eine Anschlussvorrichtung für ein Ablaufsystem, insbesondere im Bereich der Linienentwässerung mit Entwässerungsrinnen und Punktentwässerung mit Straßenabläufen, zur Entwässerung von Verkehrsflächen gelöst, wobei die Anschlussvorrichtung einen Aufsatzstutzen, der mit einem Aufsatz zum Ableiten von Wasser verbindbar ist, und einen Ablaufkörper aufweist, der mit einem Abwassersystem verbindbar ist. Zwischen dem Aufsatzstutzen und dem Ablaufkörper ist ein Schalungsstutzen angeordnet, der sich in den Ablaufkörper erstreckt. Der Schalungsstutzen weist einen Auflageflansch auf, der zwischen den axialen Enden des Schalungsstutzens angeordnet ist.Specifically, the task is solved by a connection device for a drainage system, in particular in the area of linear drainage with drainage channels and point drainage with street gullies, for the drainage of traffic areas, the connection device having an attachment socket, which can be connected to an attachment for draining water, and a drainage body , which can be connected to a sewage system. A formwork socket is arranged between the attachment socket and the drain body and extends into the drain body. The formwork socket has a support flange which is arranged between the axial ends of the formwork socket.

Eine erfindungsgemäß ausgebildete Anschlussvorrichtung mit Schalungsstutzen verhindert das Verschmutzen des Ablaufkörpers durch Mörtel oder andere Baustoffe. Der Schalungsstutzen dient dabei als Hilfsmittel um den Baustoff, insbesondere Mörtel, in der notwendigen Menge bündig um den Schalungsstutzen aufzutragen, um Hohlräume zu vermeiden. Der Auflageflansch dichtet den Ablaufkörper zusätzlich ab. Des Weiteren ermöglicht der Schalungsstutzen gegebenenfalls eine Anpassung in der Höhe und ist mit wenig Aufwand und geringen zusätzlichen Kosten realisierbar.A connection device designed according to the invention with formwork socket prevents the drain body from becoming contaminated by mortar or other building materials. The formwork socket serves as an aid to apply the building material, in particular mortar, in the necessary amount flush around the formwork socket in order to avoid cavities. The support flange additionally seals the drain body. Furthermore, the formwork socket allows the height to be adjusted if necessary and can be implemented with little effort and minimal additional costs.

Zwar ist aus DE 82 25 072 3 bereits bekannt, zylindrische Schalkörper bei der Montage einer Anschlussvorrichtung zu verwenden. Dies geschieht aber nicht, um eine Verschmutzung des Ablaufkörpers zu verhindern, sondern um einen Arbeitsschritt einzusparen.Although it's over DE 82 25 072 3 It is already known to use cylindrical formwork bodies when assembling a connection device. However, this is not done to prevent the drain body from becoming dirty, but rather to save a work step.

Bevorzugte Ausführungsformen der Erfindung sind in den Unteransprüchen angegeben.Preferred embodiments of the invention are specified in the subclaims.

Vorzugsweise ist bei der Anschlussvorrichtung der Auflageflansch so gestaltet, dass er Aussparungen für die Schraubverbindungen des Ablaufkörpers aufweist. Dies hat den Vorteil, dass der Schalungsstutzen zentriert und seine axiale Rotation begrenzt wird.Preferably, the support flange in the connecting device is designed in such a way that it has recesses for the screw connections of the drain body. This has the advantage that the formwork socket is centered and its axial rotation is limited.

Der Schalungsstutzen bildet ein Mittel zur Höhenanpassung, so dass die Anschlussvorrichtung an die jeweilige Höhe des Straßenbelags angepasst werden kann.The formwork socket forms a means for height adjustment, so that the connecting device can be adapted to the respective height of the road surface.

Der im montierten Zustand zur Oberfläche hingerichtete Abschnitt des Schalungsstutzens kann gleichlang oder länger sein, als der sich im Ablaufkörper erstreckende Abschnitt. Somit eignet sich der Schalungsstutzen auch für dickere Mörteldecken.The section of the formwork socket facing the surface in the assembled state can be of the same length or longer than the section extending in the drain body. This means that the formwork socket is also suitable for thicker mortar ceilings.

Der Schalungsstutzen weist erfindungsgemäß oberhalb des Auflageflansches Drainageöffnungen auf, die über den Umfang verteilt angeordnet sind. Dies hat den Vorteil, dass Feuchtigkeit aus dem Mörtel abgeführt wird. Vorteilhafterweise ist der Außendurchmesser des Schalungsstutzens kleiner als der Innendurchmesser des Ablaufkörpers ausgebildet. Der dadurch entstehende Ringspalt ist durch den Auflageflansch verdeckt und gleicht Bautoleranzen aus.According to the invention, the formwork socket has drainage openings above the support flange, which are arranged distributed over the circumference. This has the advantage that moisture is removed from the mortar. Advantageously, the outer diameter of the formwork socket is smaller than the inner diameter of the drain body. The resulting annular gap is covered by the support flange and compensates for construction tolerances.

Der Aufsatzstutzen ragt vorteilhafterweise über die Drainageöffnungen hinaus, damit kein Abwasser durch die Öffnungen austreten kann.The attachment nozzle advantageously protrudes beyond the drainage openings so that no wastewater can escape through the openings.

Der Aufsatzstutzen kann eine am zum Aufsatz zugewandten Ende eine Verjüngung aufweisen, um das Einstecken in den Aufsatz zu erleichtern.The attachment socket can have a taper at the end facing the attachment to make it easier to insert it into the attachment.

Vorzugsweise ist der Durchmesser des Aufsatzstutzens kleiner als der Durchmesser des Schalungsstutzens. Dadurch wird das Einführen des Aufsatzstutzens in den Schalungsstutzen erleichtert, eine horizontale Ausrichtung der Rinnenkörper ermöglicht und Einbautoleranzen, bspw. Ungenauigkeiten, wie Neigungen und Produkttoleranzen, bei der Montage ausgeglichen.Preferably, the diameter of the attachment socket is smaller than the diameter of the formwork socket. This makes it easier to insert the attachment socket into the formwork socket, enables horizontal alignment of the channel bodies and compensates for installation tolerances, such as inaccuracies such as inclinations and product tolerances, during assembly.

Der Aufsatzstutzen kann einen Kragen aufweisen, der sich in Umfangsrichtung um diesen erstreckt. Dieser dient als Schutz der Steckverbindung und Montagehilfe.The attachment socket can have a collar which extends around it in the circumferential direction. This serves as protection for the plug connection and as an assembly aid.

Im Rahmen der Erfindung wird ferner ein Ablaufsystem mit einer erfindungsgemäßen Anschlussvorrichtung offenbart und beansprucht. Das Ablaufsystem umfasst einen Rinnenkörper, bevorzugt eine Hohlbordrinne aus Polymerbeton. Dieser ist mit dem Aufsatzstutzen der Anschlussvorrichtung verbindbar. Andere Aufsätze sind möglich, insbesondere Punktabläufe, wie Straßen- oder Hofabläufe.Within the scope of the invention, a drainage system with a connection device according to the invention is also disclosed and claimed. The drainage system includes a gutter body, preferably a hollow gutter made of polymer concrete. This can be connected to the attachment socket of the connection device. Other attachments are possible, especially point drains, such as street or yard drains.

Der Aufsatzstutzen kann fest mit dem Rinnenkörper verbunden sein. Mit anderen Worten ist es möglich, den Ablaufstutzen als festen Bestandteil des Rinnenkörpers auszubilden. Diese Variante ist für die lineare Entwässerung von Verkehrsflächen besonders geeignet.The attachment socket can be firmly connected to the gutter body. In other words, it is possible to design the drain connection as an integral part of the channel body. This variant is particularly suitable for the linear drainage of traffic areas.

Im Rahmen der Erfindung wird ein Verfahren zur Montage eines Ablaufsystems mit einer erfindungsgemäßen Anschlussvorrichtung offenbart und beansprucht. Der Schalungsstutzen wird mit dem Auflageflansch auf den Ablaufkörper gesetzt. Anschließend wird ein Baustoff, insbesondere Mörtel, zu einer oberen Baustoffebene aufgetragen. Ein Teil des oberen Abschnitts des Schalungsstutzens wird vor dem Auftragen des Baustoffs eingekürzt, so dass die Oberkante des Schalungsstutzens auf der gleichen Ebene oder unterhalb der oberen Baustoffebene angeordnet ist.Within the scope of the invention, a method for assembling a drain system with a connection device according to the invention is disclosed and claimed. The formwork socket is placed on the drain body with the support flange. A building material, in particular mortar, is then applied to an upper building material level. A part of the upper section of the formwork socket is shortened before the building material is applied, so that the upper edge of the formwork socket is arranged on the same level or below the upper building material level.

Im Rahmen der Erfindung wird ein Verfahren zur Montage eines Ablaufsystems mit einer erfindungsgemäßen Anschlussvorrichtung offenbart und beansprucht. An der oberen Baustoffebene wird eine zum Schalungsstutzen angeordnete Fase angearbeitet. Der gekürzte Schalungsstutzen liegt unterhalb der oberen Baustoffebene. Beim Einbau des Rinnenkörpers, im Bereich zwischen dem Kragen, dem Aufsatzstutzen und der Fase verbleibt ein den Aufsatzstutzen umlaufender Freiraum. Der Freiraum wird beim weiteren Einbau des Rinnenkörpers durch den noch plastischen Mörtel ganz oder zumindest teilweise wieder geschlossen.Within the scope of the invention, a method for assembling a drain system with a connection device according to the invention is disclosed and claimed. A chamfer arranged to form the formwork socket is created on the upper building material level. The shortened formwork socket is located below the upper building material level. When installing the gutter body, in the area between the collar, the attachment socket and the chamfer, there remains a free space surrounding the attachment socket. When the gutter body is further installed, the free space is completely or at least partially closed again by the still plastic mortar.

Die Erfindung wird im Folgenden anhand eines Ausführungsbeispiels unter Bezug auf die beigefügten schematischen Zeichnungen mit weiteren Einzelheiten erläutert.The invention is explained in further detail below using an exemplary embodiment with reference to the attached schematic drawings.

In Fig. 1 ist eine Anschlussvorrichtung mit Ablaufsystem dargestellt. Der Ablaufkörper 12 ist im Gebrauch in festem Untergrund, vorzugsweise Beton, mittels eines Pressflansches 21 befestigt und an ein Abwassernetz angeschlossen. Der Auflageflansch 13 liegt flächig auf dem Pressflansch 21 des Ablaufkörpers 12 auf. Wahlweise kann der Auflageflansch 13 Aussparungen 14 für die Schraubverbindungen 15 des Ablaufkörpers 12 aufweisen, welche die Zentrierung und Begrenzung der axialen Rotation des Schalungsstutzens 10 ermöglichen.In Fig. 1 A connection device with a drainage system is shown. During use, the drain body 12 is fastened to solid ground, preferably concrete, by means of a press flange 21 and connected to a sewage network. The support flange 13 lies flat on the press flange 21 of the drain body 12. Optionally, the support flange 13 can have recesses 14 for the screw connections 15 of the drain body 12, which enable the centering and limitation of the axial rotation of the formwork socket 10.

Der Auflageflansch 13 befindet sich zwischen den axialen Enden des Schalungsstutzens 10 und erstreckt sich zum Teil in den Ablaufkörper 12. Oberhalb des Auflageflansches 13, auf dem Abschnitt des Schalungsstutzens 10, der direkt mit dem Mörtel in Kontakt steht, sind Drainageöffnungen 16 vorhanden, um Feuchtigkeit aus dem dränfähigen Mörtel abzuführen. Auf dem frei liegenden Ende des Schalungsstutzens 10 sitzt der Aufsatzstutzen 11. Dieser weist einen Kragen 18 auf, der sich in Umfangrichtung erstreckt. Der Kragen 18 verhindert ein zu tiefes Einstecken des Aufsatzstutzens 11, schützt die Verbindung und erleichtert die Montage. Der Aufsatzstutzen 11 ist in den Rinnenkörper 19, insbesondere in eine Hohlbordrinne, mit seinem verjüngten Ende 17 voran eingesteckt und wird durch eine Dichtung, insbesondere eine Labyrinthdichtung 20, arretiert. Der Innendurchmesser, der zur Oberfläche hin ausgerichteten Bauteilenden, ist stets größer als der Außendurchmesser des jeweils aufgesetzten Bauteils. Das hat den Zweck, dass die Bauteile sich jeweils zum Teil ineinander erstrecken und eine Montage von oben einfach möglich ist. Nach abgeschlossener Montage und Verlegung der Asphaltschicht ist der Rinnenkörper 19, insbesondere die Hohlbordrinne, die einzige von außen sichtbare Komponente des Ablaufsystems.The support flange 13 is located between the axial ends of the formwork socket 10 and partially extends into the drain body 12. Above the support flange 13, on the section of the formwork socket 10 that is in direct contact with the mortar, there are drainage openings 16 to drain moisture from the drainable mortar. The attachment socket 11 sits on the exposed end of the formwork socket 10. This has a collar 18 which extends in the circumferential direction. The collar 18 prevents the attachment socket 11 from being inserted too deeply, protects the connection and makes assembly easier. The attachment socket 11 is inserted into the gutter body 19, in particular into a hollow gutter, with its tapered end 17 first and is locked by a seal, in particular a labyrinth seal 20. The inside diameter of the component ends facing the surface is always larger than the outside diameter of the attached component. The purpose of this is that the components partially extend into each other and assembly from above is easily possible. Once the asphalt layer has been assembled and laid, the gutter body 19, in particular the hollow gutter, is the only component of the drainage system that is visible from the outside.

Fig. 3 zeigt ein erfindungsgemäßes Ausführungsbeispiel einer Anschlussvorrichtung gemäß Fig. 1 vor der Montage des Rinnenkörpers 19, insbesondere der Hohlbordrinne. Der Aufsatzstutzen 11 ist mit dem Rinnenkörper 19 verbunden. Der Schalungsstutzen 10 liegt mit dem Auflageflansch 13 auf den Schraubverbindungen 15 des Pressflansches 21 auf. Um den Schalungsstutzen 10 ist eine Baustoffebene 22 aufgetragen. Die Baustoffebene 22 ist höher als der Rand des Schalungsstutzens 10. Die Baustoffebene 22 bildet eine Fase 23, die zum Schalungsstutzen 10 weist und schließt bündig (oder wenigstens annähernd bündig) mit dessen Rand ab. Zwischen dem Kragen 18, dem Aufsatzstutzen 11 und der Fase 23 ist ein den Aufsatzstutzen 11 umlaufender Freiraum 24 ausgebildet. Durch den Freiraum 24 kann beim Aufsetzen des Rinnenkörpers 19 kein Mörtel in den Ablaufkörper 12 und/oder in den Schalungsstutzen gelangen. Der Freiraum zwischen der Fase 23 und dem Schalungsstutzen 10 wird beim weiteren Einbau des Rinnenkörpers durch den noch plastischen Mörtel ganz oder zumindest teilweise geschlossen Zudem ermöglicht es der Freiraum 24 einen Höhenausgleich des Rinnenkörpers 19, insbesondere der Hohlbordrinne, beim Einbau vorzunehmen. Fig. 3 shows an embodiment of a connection device according to the invention Fig. 1 before assembling the gutter body 19, in particular the hollow-border gutter. The attachment socket 11 is connected to the gutter body 19. The formwork socket 10 rests with the support flange 13 on the screw connections 15 of the press flange 21. A building material level 22 is applied around the formwork socket 10. The building material level 22 is higher than the edge of the formwork socket 10. The building material level 22 forms a chamfer 23 which points towards the formwork socket 10 and is flush (or at least approximately flush) with its edge. Between the collar 18, the attachment socket 11 and the chamfer 23, a free space 24 surrounding the attachment socket 11 is formed. Due to the free space 24, no mortar can get into the drain body 12 and/or the formwork socket when the gutter body 19 is put on. The free space between the chamfer 23 and the formwork socket 10 is completely or at least partially closed during further installation of the gutter body by the still plastic mortar. In addition, the free space 24 makes it possible to adjust the height of the gutter body 19, in particular the hollow gutter, during installation.

Die beschriebene Anordnung kann in vielfältiger Weise abgeändert und eingesetzt werden. Sie eignet sich in ihrer beschriebenen Form zur linearen Entwässerung von Verkehrsflächen mit Entwässerungsrinnen, kann aber auch zur punktuellen Entwässerung mit Straßenabläufen verwendet werden. Der Schalungsstutzen 10 kann so ausgebildet sein, dass der Kragen, der den Auflageflansch 13 bildet, so gestaltet ist, dass er mit dem Ablaufkörper 12 abdichtend verbindbar, ist. Der Kragen kann auch als separates Bauteil ausgebildet sein, der mittels einer Schelle in der gewünschten Höhe befestigt wird. Dadurch wäre ein Ablängen des Schalungsstutzens 10 hinfällig. Auch andere Befestigungsarten, wie Schrauben und Muttern, welche die beiden Bauteile durch vorgebohrte Löcher verbinden, oder Rastnasen mit korrespondierenden Öffnungen sind denkbar.The arrangement described can be modified and used in a variety of ways. In the form described, it is suitable for the linear drainage of traffic areas with drainage channels, but can also be used for selective drainage with road gullies. The formwork socket 10 can be designed in such a way that the collar, which forms the support flange 13, is designed in such a way that it can be sealingly connected to the drain body 12. The collar can also be designed as a separate component that is attached at the desired height using a clamp. This would make it unnecessary to cut the formwork socket 10 to length. Other types of fastening, such as screws and nuts that connect the two components through pre-drilled holes, or locking lugs with corresponding openings are also conceivable.
