Definitions
- the invention relates to a channel for draining a road surface, for example, according to the preamble of patent claim 1.
- a drainage channel in which the individual channel sections are each connected to one another by a locking coupling.
- a rib of a first channel section engages in a groove of a second channel section.
- Adhesive is placed in the groove to strengthen the connection.
- a drainage canal from the U.S. 5,718,537 A known, in which the individual channel elements each have a projection and a recess. To connect the channel elements, the projection of one element engages in the recess of the other element in the longitudinal direction of the drainage channel.
- the retaining grooves for the seals in the known channels follow the cross-sectional profile of the channel interior.
- this does not pose a major problem since relatively large radii of curvature are provided following the interior profiles.
- the cross-sectional profile is V-shaped rather than semi-circular, the seals will curve too much, leading to leaks and ruptures with prolonged use.
- the invention is based on the object of demonstrating a channel of the type mentioned at the outset in such a way that increased tightness is ensured with improved ease of installation and durability at the same time.
- this object is achieved by a channel for drainage, e.g Seal is provided on a holding surface of the channel, wherein the first end of the channel has the holding surface and wherein a bottom of the channel has a cross-sectional profile that deviates from a semi-circular shape, solved in that the holding surface has a cross-sectional profile viewed in the direction of the longitudinal axis , which deviates from that of the sole in that a maximum radius of curvature is ensured at every point of the holding surface and thus of the seal.
- An essential point of the invention is that the seal does not follow the contour of the edge to be sealed, as is usually the case, but rather a very specific shape is selected, which improves the durability and tightness of the overall arrangement.
- the cross-sectional profile of the holding surface—and thus the curvature of the seal— is essentially semicircular. Such a steady course of curvature brings with it the minimal expansion loads during bending.
- the holding surface preferably has a holding slot for receiving a fastening leg of the seal, the holding slot preferably being provided on a side of the holding surface lying on the inside in the longitudinal direction of the channel. This ensures that the seal is held securely in a simple manner.
- a sealing strip for the sealing connection with the seal of a further channel is preferably provided at the second end of the channel opposite the holding surface.
- the sealing strip and the seal are in sealing engagement in a direction perpendicular to the channel longitudinal axis, which means that the end faces do not have to sit on top of one another with millimeter precision, as is necessary in the prior art, according to the present invention.
- the channel preferably has a contact surface for contacting the seal in a direction perpendicular to the longitudinal axis of the channel. This can be formed on the sealing strip.
- the sealing strip and the seal are formed so deep in the direction of the longitudinal axis of the channel that tilting of two adjacent channels is made possible with a sealing connection of the sealing strip with the seal.
- channels can run in (slight) curves or in some other way corresponding to the surface contours.
- the sealing strip preferably has the aforesaid contact surface on an inwardly facing surface, which comes into sealing engagement with the seal.
- the channel 10 has side walls 11, 12 and a bottom 13 and end walls 14 and 15.
- the interior or the base of the channel 10 is designated by the reference number 16 .
- a seal 30 is connected to the trough 10 by a mounting leg 31 which seats in a corresponding slot of the trough 10, described in more detail below.
- the seal 30 has an outer sealing lip 32 and an inner sealing lip 33 . It is also possible to dispense with the sealing lip 32 so that the base body of the seal comes into contact with the contact surface 41 .
- a sealing strip 40 is provided at a second end 18 and has a contact surface 41 directed inwards. If two channels of the type shown here are put together in such a way that the first end 17 of a first channel 10 is connected to a second end 18 of a second channel, the outer sealing lip 32 comes into sealing contact with the contact surface 41 of the sealing strip 40, as is the case here below based on the Figures 4-6 is explained in more detail.
- a first end 17 of a channel 10 is shown in a horizontal section. From this it can be seen that the end 17 has a protruding holding surface 20 and a slot 21 extending the holding surface in the longitudinal direction of the channel 10.
- the in figure 5 Seal 30 shown has a fastening leg 31 with toothed lips, which can be inserted into the slot 21 and is firmly clamped there. The inner sealing lip 33 then sits firmly on the holding surface 20, while the outer sealing lip 32 protrudes outwards. If you now put two channels 10, 10' together, then - as in 6 shown - a first end 17 'of the channel 10' with the second end 18 of the channel 10 in sealing connection.
- successive channels do not necessarily have to meet tightly or closely. They may have some play so that the successive gutters can be tilted against each other without reducing the sealing effect.
- the end walls 14, 15 or the ends 17, 18 of a channel are shown side by side to show that the profile of the base 16 of the channel 10 differs from the profile of the seal 30 or the sealing strip 40. While the profile of the base 16 of the channel 10 is approximately V-shaped with a very small radius of curvature R1, the profile of the seal 30 or the sealing strip 40 is uniform in its area of curvature, i.e. curved along a semicircle with a much larger radius of curvature R2 .
- seal 30 and the sealing strip 40 can also be arranged the other way round, ie the seal 30 points inwards and the sealing strip 40 with its contact surface 41 points outwards. Another way of fastening the seal 30 to the holding surface 20 is also possible.

Description
Die Erfindung betrifft eine Rinne zur Entwässerung zum Beispiel einer Straßenoberfläche nach dem Oberbegriff des Patentanspruches 1.The invention relates to a channel for draining a road surface, for example, according to the preamble of patent claim 1.
Bei derartigen Entwässerungsrinnen wird zunehmend die Forderung gestellt, dass der Rinnenstrang als solcher insgesamt dicht ist. Dies bedeutet, dass die Verbindungen zwischen den einzelnen Rinnenelementen dicht sein müssen. Hierzu werden, wie dies beispielsweise in der
Aus der
Des Weiteren ist ein Entwässerungskanal aus der
Wenn Dichtungen eingelegt werden, so folgen bei den bekannten Rinnen die Haltenuten für die Dichtungen dem Querschnittsprofil des Rinnen-Innenraums. Bei den vorgenannten Rinnen stellt dies kein großes Problem dar, da relativ große Krümmungsradien den Innenraumprofilen folgend vorgesehen sind. Dann aber wenn - wie dies zur Verbesserung der hydraulischen Eigenschaften oftmals gemacht wird - das Querschnittsprofil eher V-förmig als halbkreisförmig ist, werden die Dichtungen zu stark gekrümmt, was zu Undichtigkeiten und Brüchen im längeren Gebrauch führt.If seals are inserted, the retaining grooves for the seals in the known channels follow the cross-sectional profile of the channel interior. In the case of the aforesaid gutters, this does not pose a major problem since relatively large radii of curvature are provided following the interior profiles. However, if - as is often done to improve hydraulic properties - the cross-sectional profile is V-shaped rather than semi-circular, the seals will curve too much, leading to leaks and ruptures with prolonged use.
Der Erfindung liegt die Aufgabe zu Grunde, eine Rinne der eingangs genannten Art dahingehend aufzuzeigen, dass eine erhöhte Dichtigkeit bei gleichzeitig verbesserter Verlegbarkeit und Haltbarkeit sichergestellt ist.The invention is based on the object of demonstrating a channel of the type mentioned at the outset in such a way that increased tightness is ensured with improved ease of installation and durability at the same time.
Diese Aufgabe wird durch eine Rinne nach Patentanspruch 1 gelöst.This problem is solved by a channel according to patent claim 1.
Erfindungsgemäß wird diese Aufgabe also durch eine Rinne zur Entwässerung z.B. einer Straßenoberfläche, umfassend ein erstes und ein zweites Ende, wobei das erste Ende einer ersten Rinne mit dem zweiten Ende einer zweiten Rinne in einer Längsachse der Rinnen verbindbar ist und zum Abdichten der Verbindung eine elastische Dichtung an einer Haltefläche der Rinne vorgesehen ist, wobei das erste Ende der Rinne die Haltefläche aufweist und wobei eine Sohle der Rinne ein von einer Halb-Kreis-Form abweichendes Querschnittsprofil aufweist, dadurch gelöst, dass die Haltefläche ein Querschnittsprofil in Richtung der Längsachse gesehen aufweist, das von demjenigen der Sohle dahingehend abweicht, dass an jeder Stelle der Haltefläche und damit der Dichtung ein maximaler Krümmungsradius sichergestellt wird.According to the invention, this object is achieved by a channel for drainage, e.g Seal is provided on a holding surface of the channel, wherein the first end of the channel has the holding surface and wherein a bottom of the channel has a cross-sectional profile that deviates from a semi-circular shape, solved in that the holding surface has a cross-sectional profile viewed in the direction of the longitudinal axis , which deviates from that of the sole in that a maximum radius of curvature is ensured at every point of the holding surface and thus of the seal.
Ein wesentlicher Punkt der Erfindung liegt also darin, dass nicht wie sonst üblich, die Dichtung der Kontur des abzudichtenden Randes folgt, sondern eine ganz eigene Form gewählt wird, welche die Haltbarkeit und Dichtigkeit der Gesamtanordnung verbessert.An essential point of the invention is that the seal does not follow the contour of the edge to be sealed, as is usually the case, but rather a very specific shape is selected, which improves the durability and tightness of the overall arrangement.
Erfindungsgemäß ist das Querschnittsprofil der Haltefläche - und damit die Krümmungsform der Dichtung - im Wesentlichen halbkreisförmig. Ein derart stetiger Krümmungsverlauf bringt die minimalen Dehnungsbelastungen beim Biegen mit sich.According to the invention, the cross-sectional profile of the holding surface—and thus the curvature of the seal—is essentially semicircular. Such a steady course of curvature brings with it the minimal expansion loads during bending.
Die Haltefläche weist vorzugsweise einen Halteschlitz zur Aufnahme eines Befestigungsschenkels der Dichtung auf, wobei der Halteschlitz vorzugsweise auf einer in Längsrichtung der Rinne innenliegenden Seite der Haltefläche angebracht ist. Dadurch ist in einfacher Weise ein sicherer Halt der Dichtung gewährleistet.The holding surface preferably has a holding slot for receiving a fastening leg of the seal, the holding slot preferably being provided on a side of the holding surface lying on the inside in the longitudinal direction of the channel. This ensures that the seal is held securely in a simple manner.
Vorzugsweise ist an dem, der Haltefläche gegenüberliegenden, zweiten Ende der Rinne eine Dichtleiste zur dichtenden Verbindung mit der Dichtung einer weiteren Rinne vorgesehen. Vorzugsweise stehen hierbei die Dichtleiste und die Dichtung in einer Richtung senkrecht zur Rinnenlängsachse in Dichteingriff, was dazu führt, dass ein millimetergenaues Aufeinandersitzen der Stirnflächen so, wie dies im Stand der Technik notwendig ist, gemäß der vorliegenden Erfindung nicht sein muss.A sealing strip for the sealing connection with the seal of a further channel is preferably provided at the second end of the channel opposite the holding surface. Preferably, the sealing strip and the seal are in sealing engagement in a direction perpendicular to the channel longitudinal axis, which means that the end faces do not have to sit on top of one another with millimeter precision, as is necessary in the prior art, according to the present invention.
Die Rinne weist vorzugsweise eine Anlagefläche zur Anlage der Dichtung in einer Richtung senkrecht zur Rinnenlängsachse auf. Diese kann auf der Dichtleiste ausgebildet sein.The channel preferably has a contact surface for contacting the seal in a direction perpendicular to the longitudinal axis of the channel. This can be formed on the sealing strip.
Vorzugsweise sind die Dichtleiste und die Dichtung derart tief in Richtung der Längsachse der Rinne ausgebildet, dass ein Verkippen zweier aneinandergrenzender Rinnen unter dichtender Verbindung der Dichtleiste mit der Dichtung ermöglicht ist. Dadurch können Rinnen in (leichten) Bögen oder sonstwie den Oberflächenkonturen entsprechend verlaufen.Preferably, the sealing strip and the seal are formed so deep in the direction of the longitudinal axis of the channel that tilting of two adjacent channels is made possible with a sealing connection of the sealing strip with the seal. As a result, channels can run in (slight) curves or in some other way corresponding to the surface contours.
Die Dichtleiste weist vorzugsweise auf einer nach innen gewandten Fläche die genannte Anlagefläche auf, welche mit der Dichtung in dichtenden Eingriff gelangt.The sealing strip preferably has the aforesaid contact surface on an inwardly facing surface, which comes into sealing engagement with the seal.
