Description

The invention relates to a sealing system according to the preamble of claim 1.

A drainage channel with these features is from the EP 1 719 848 A2 previously known.

Such a drainage channel sealed in the joint area is also known from the German patent DE 195 20 801 C1 previously known. Alternatively, the channel elements can also be connected to each other in the joint area by a connecting element which engages under the grooves in the joint region, the connecting element being connected to the two end-side groove ends with the interposition of a sealing element. Such a solution is known from the German patent application DE 10 2005 020 753 A1 previously known.

Again in an alternative embodiment according to the DE 93 19 836 U1 can be integrally produced Entwässerungsrinnen also be joined together that special flap parts are formed in their joint area, which are formed as the other channel end receiving connection shoes, so that the channel ends are again connected to each other with the interposition of a sealing element.

Basically, such drainage channels are optionally made of concrete, steel, plastic, fiber concrete or polyester concrete and used for drainage of roads, squares, storage areas or traffic areas. In most cases, such drainage channels on tongue and groove systems, which mesh when laying and above all serve as installation aid of the gutters. An automatic seal is not made with these compounds in most cases. If you want to ensure an efficient sealing of the gutters in the joint area, so special sealing measures are required. Here, as explained above, either subsequently introduced sealing compounds in prepared grooves or additional connection elements used as sealing sleeves.

All mentioned subsequent or additional construction measures are associated with additional costs and are therefore only in exceptional cases or at least rarely installed. This is not least because the current DIN standards and the European standard EN 1433, concerning drainage channels for traffic areas, regularly a leak test for the used Rinnenkörper requires as such, but no rules regarding the connection between the individual channel sections provides.

Based on this prior art, the invention is based on the object to make the butt joint between the drainage channels involved in this connection so that directly when laying the drainage channels automatically, i. without additional subsequent sealing effort or subsequently attached elements a tight butt joint, and over the entire circumference of the frontal connection of the participating drainage channels, is made.

The solution of this object is achieved by means of a sealing system with the features of the current claim 1. Advantageous embodiments and further developments of this invention can be taken from the dependent claims 2 to 7.

In addition to the previously known tongue and groove connection, which usually causes only a pull-out protection of the butt joint in the direction of the longitudinally extending drainage channels, the solution according to the invention provides for an interaction of an additional locking element on the spring side with an additional complementary recess on the groove side, such that As a result, a fuse of the tongue and groove connection is also effected vertically to the longitudinal extent of the connected drainage channels and this is thus prevented against displacement upwards or downwards against each other in conjunction with a cancellation of the seal caused by the connection. It is irrelevant for the object of the invention, whether the locking element on the spring or the groove side or the complementary retaining element on the tongue or spring side of the butt joint are arranged. All mentioned embodiments are to be regarded as part of the invention as well as the same effect. In an inventive embodiment of this compound, the locking element engages on the tongue or spring side of the butt joint to form the butt joint in a corresponding recess on the spring or groove side of the other drainage channel a, so that in this way a backup of the connection is made in the vertical direction to the longitudinal extent of the participating drainage channels.

In addition, a further locking element in the solution according to the invention ensures that the connection is secured transversely to the longitudinal extent of the two drainage channels and thus they are pressed together in this direction, so that the seal is secured in all three axes of their spatial extent and pressed in such a way in that a tight connection is established between the participating drainage channels.

In addition, the tightness of the tongue and groove connection according to the invention can be further improved by the fact that the connection of the participating drainage channels is made with the interposition of a sealing profile.

In a further improved embodiment can be arranged on the tongue side a second locking element and on the groove side with this additional spring element corresponding second recess, wherein both the additional locking element as well as the additional recess respectively above the first locking element or above the first recess to the corresponding Drainage channels are formed. This has the advantage that in the event that due to a deformation of the arranged on the spring side drainage channel in the direction of the adjacent, on the groove side of the adjoining gutter projecting detent element with its corresponding recess disengaged, a second locking element is available, if necessary, ensuring the continuity of the sealing connection between the adjacent drainage channels, in particular while maintaining the sealing connection.

In another improved embodiment of this embodiment of the compound, the respective additional second locking element is provided in contrast to the first locking element with a downwardly facing hook portion corresponding to a corresponding undercut of the respective second recess of the respective adjacent drainage channel, ie when connecting these adjoining drainage channels with the undercut is engaged. This has the advantage that, in particular by the interaction of the first locking element with the corresponding recess and the second locking element with the respective corresponding recess a release of the connection, which is caused by the two locking elements, even then no longer seems possible if vertical forces or shear forces act on the involved gutter elements.

In a preferred embodiment, a foam or moss rubber-like profile seal can be used as a seal or as inserted between the drainage channels sealing element.

The solution of the invention provides to produce the drainage channels made of concrete or polyester concrete, wherein the additional connecting elements are realized in the groove and / or spring area additionally inside and / or outside applied plastic inlays cost.

The invention will be explained in more detail below by way of example with reference to the exemplary embodiments illustrated in the drawing, without the invention being restricted to the exemplary embodiments.

FIG. 1 shows in a perspective view of an open butt joint between two drainage channels 1, 2, wherein the one drainage channel 1 is formed in the joint area as a groove side, while the other drainage channel 2 is formed in the joint area as a spring side. For this purpose, one drainage channel 1 projects in the direction of the adjacent other drainage channel 2, over the entire profile of the drainage channel 1 circumferential Nutsteg 3, while the other drainage channel 2 also has a projecting over the entire channel profile in the direction of a drainage channel 1 spring bar 4.

In this case, the spring bar 4 is provided with a circumferential projecting edge 5, which engages in the joining of the two drainage channels 1 and 2 in a corresponding circumferential groove 6 of the Nutstegs 3. When the tongue and groove connection is closed, a pull-out protection of the butt joint is effected in the longitudinal direction of the two drainage channels 1, 2 connected to one another. In addition, two projecting locking elements 7 are integrally formed on the spring bar 4 on the outer circumference on the outer circumference, which are engageable with two corresponding with the locking elements 7 recesses 8 of the Nutstegs 3 in such a way that an additional backup of the butt joint of the two involved drainage channels 1, 2 vertically to the longitudinal extent of the two drainage channels 1, 2 is effected.

FIG. 2 again shows an open butt joint between two drainage channels 1, 2 in a perspective view.

To the representation in FIG. 1 identical and functionally identical features, such as the Nutsteg 3 and the spring bar 4, the circumferential edge 5 and the circumferential groove 6 and the locking element 7 and the corresponding recess 8 are in FIG. 2 denoted by the identical reference numerals.

In the FIG. 2 Shock connection shown differs from that in FIG. 1 shown butt joint characterized in that in addition to the locking element 7, a further locking element 7 'with a corresponding recess 8' in the region of the Nutstegs 3 are each formed on the drainage channels 1 and 2 involved in the connection. The hereby realized double safety of the butt joint causes a higher tightness of the connection and a better stability of the formed connection between the drainage channels 1 and 2 involved.

FIG. 3 shows the in FIG. 2 Shock connection shown in the closed design, ie such that the spring bar 4 is latched to the Nutsteg 3 and the locking elements 7, 7 'with the corresponding recesses 8, 8' are locked.

FIG. 4 shows the in FIG. 3 shown closed butt joint in an in FIG. 3 Section IV-IV. From this view it becomes clear that both the locking element 7 and the locking element 7 'in the corresponding recesses 8, 8' engages and thus causes the described double-locking the connection.

FIG. 5 again shows an open butt joint of the drainage channels 1, 2 involved in the butt joint in a yet further improved embodiment. Again, identical features such as the Nutsteg 3, the spring bar 4, the locking element 7 and the corresponding recess 8 are provided with identical reference numerals. In place of the additional locking element 7 here is a hook member 10 has entered, which is intended to be brought into engagement with the corresponding undercut recess 11 in engagement.

FIG. 6 shows the in FIG. 5 Shock connection shown in a partial view in a closed design. In this illustration, the hook element 10 is in engagement with the undercut recess 11.

FIG. 7 shows the closed butt joint in an in FIG. 6 with VII - VII designated sectional view. According to this illustration, when the butt joint is closed, the locking element 7 engages in the recess 8, while at the same time the hook element 10 is hooked under engagement behind the undercut of the undercut recess 11. From this representation it is clear that even if the drainage channel 2 could migrate downwards with the spring bar 4 and the molded hook element 7 due to a settling movement of the earth region, so that the locking element 7 could be disengaged from the recess 8, such an evasive movement in that the hook element 10 is received in the undercut recess 11, thus settling down the drainage channel element 2 is excluded.

Conversely, the drainage channel element 2 also can not migrate upwards, because in this respect the drainage channel element 2 is fixed in the recess 8 by the engagement of the latching element 7. The butt joint is thus secured not only in horizontal, but also in vertical terms.

The above thus described the formation of a butt joint between two substantially identical drainage channels made of concrete or polyester concrete, which is secured in contrast to the prior art in at least two, preferably three conceivable, mutually orthogonal directions of movement and by the resultant contact pressure and / or a additional seal is largely or completely sealed, which achieved by appropriate Kunststoffinlays in a simple manner, the above-described improved sealing becomes.
