Description

The invention relates to a multi-part plug-in channel having an at least substantially U-shaped trough portion comprising a sole which is delimited on both sides by two sole wall flanges which enclose a substantially right angle with the sole, wherein the sole wall flanges at their top wall end respectively with in Direction of the adjoining in the installed state adjacent side wall parts connecting elements are provided such that the sole member separate side wall parts, which are provided with corresponding receiving devices, are engageable with the protruding connecting elements of the sole wall flanges so that the side wall portions on both sides of the sole on the sole wall flanges to form a at least substantially U-shaped drainage channel are attachable.

Such a drainage channel is from the DE 197 45 480 A1 previously known. The previously known drainage channel consists of a channel body and extension parts, which can be plugged on both sides of the upwardly directed legs of the channel body such that the legs of the Channel body are height or angle adjustable, so that the drainage channel different depth and terrain slopes can be adjusted.

Also from the European patent EP 1 849 924 B1 For example, a retention channel module is known for constructing a retention channel for underground storage of surface water, this module being composed of several shell parts.

From the WO 2010/047720 A1 a modular producible drainage channel is previously known, comprising an at least approximately U-shaped trough part, which comprises a sole which is bounded on both sides by two sole wall flanges, each having a top side, such as for receiving a cover of the drainage channel. Alternatively, however, in each case a rail element can be placed on the two frame elements such that the rail elements each overlap a Zargenelement form fit. In this case, one or more hook element / e overlaps the frame member in the attachment of the rail element, so that a first determination of the mounted rail is achieved transversely to the longitudinal extent of the previously known drainage channel. In a second step, the patch rail is then moved in the longitudinal direction of the previously known drainage channel until additional snap elements, which are hook-shaped, engage in corresponding corresponding recesses of the adjacent Zargenelements. As a result, both a pull-out protection of the patch rail element in the vertical direction and a backup of the patch rail elements against a possible longitudinal displacement is realized relative to the drainage channel. Also from the DE 10 2005 008 819 A1 is a floor duct element that can be produced in modular design, previously known, this floor duct element consists of a finished part, comprising a U-shaped cross-section, ie a sole pan with side flanges arranged on both sides, which are closed on the upper side of at least one removable frame on which a gutter cover placed is. This is a precast concrete element. The arrangement of an adapter component between the finished part and the frame, it should be possible to adapt the floor duct system with relatively little effort to changing environmental conditions. In all cases, the cover of the bottom channel element, which is inserted into the frame, bolted to the Zargenelement, the underlying adapter element and the side flanges of the precast concrete part.

From the US 2005/025572 A1 is another previously known modular gutter system, in which a sole member is connected to side walls via a plug connection.

From the DE 10 2010 044 447 A1 is a slot attachment for a gutter body previously known, the gutter body is completed on the top side of a cover. This cover is provided with guide means for fixing a slit-shaped element for the realization of a slit-shaped water inlet. It is therefore the modular structure of a slot channel.

The advantage of the multi-part plug-in channel is that side wall flanges of different heights can be plugged onto the respective pan section. Another advantage of this solution is that the not yet mated Gulles can be transported and stored less space consuming, because the storage of items that are partially or completely stackable, takes less storage and transport volume to complete, as in a complete, mostly U-shaped drainage channel.

However, it is problematic to connect the individual parts of the Entwässerungsrinnenabschnitte, some of which have a length of one meter and more, forming a sufficiently stable and possibly even sealed connection with each other, since due to the large-sized dimensions correspondingly large component tolerances must be considered so that it requires a sophisticated connection technology, on the one hand produces a secure connection, but on the other hand, it also allows to connect the components with little tool and assembly costs.

Based on this problem, the invention is based on the object to provide an improved multi-part plug-in channel, in which the individual parts of the plug-in channel, so here in particular the side wall parts with the central part of the tub, to form a possible closed connection as simple as possible can be joined to each other.

The solution of this object is achieved according to claim 1, characterized in that the side wall parts are each connected to the trough part by means of a stepped joining technique by the actual connection of the side wall parts with the trough part first the connection of at least one fishing guides is preceded in time, the first for a first determination of Side wall part with respect to the trough part effect and in particular their relative mobility confine the trough part, before then the final connection is made by a snap connection. In this case, the first catch guide restricts the relative movability of the side wall part in relation to the pan part in the longitudinal direction of the plug channel before the second catch guide following in the joining process then fixes the relative movability of the side wall part with respect to the pan part also transversely to the longitudinal extension of the pan part.

Advantageous embodiments of the invention can be taken from the dependent claims 2 to 15.

In an improved embodiment, a joining process in time subsequent third catch guide ensures that the side wall part to be joined after the engagement of the third catch guide also defined in its relative movement in the vertical direction, ie orthogonal to Festlegungswirkung the first and second catch guide in the sense of a provisional assurance of Seitenwandflanschs is.

In a concrete embodiment, the joining process of the side wall part on the trough part is realized in that the projecting in the direction of the adjacent side wall part latching projections are formed in different heights, so that in the joining process, the engagement of the catch guides takes place in succession.

In a further concrete embodiment, the connecting elements of the sole wall flanges projecting in the direction of the side wall parts to be joined and / or of the corresponding recesses of the side wall parts are designed differently such that a respective different fixing of the side wall parts relative to the adjacent one Trough part, in particular with respect to different directions of relative movement, is effected.

In an improved embodiment, in addition to the protruding in the direction of the adjacent side wall portions locking projections of the catch guides another index projection which is connectable to a corresponding index recording of the side wall part, arranged on the sole wall flanges, which ensures that the side wall parts can only be mounted in the correct position on the adjacent part of the tub because only in this position, the index projection engages in the corresponding index recording of the respective adjacent side wall part.

In a further concretized embodiment, the connecting elements of the catch guides, that is, the latching projections arranged on the tub part, and the corresponding recesses of the side wall parts are each formed in pairs. In this case, the catch guide pairs described, ie the mentioned locking projections on the tub part and the corresponding receiving devices of the side wall part, arranged symmetrically to an imaginary center line transversely to the longitudinal extent of the plug channel, wherein in the joining order first catch guide pair is arranged inside symmetrical to the imaginary center line and the second fishing guide pair further outward, in turn, each symmetrically to the imaginary center line, is arranged. In this way it is ensured that the lowest tolerances are to be taken into account in the first catching guide pair which first engages because the smallest distance exists between the latching projections forming the catching guide pair and the correlating receiving elements, the tolerances depending on this increase from the increasing distance to the second fishing guide pair. This is acceptable, however, because the second pair of fishing guide, as already mentioned, in the joining process subsequently engage, so that at this time already a first and correct position locking of the side wall portion is done relative to the central trough part of the gutter, so due to this first determination despite the possibly larger deviations a secure joining process is ensured.

In a further embodiment, the final connection of the side wall parts with the central trough part is ensured by means of a snap connection which engages only after the catch guides by means of two snap connection pairs. In this case, the Schnappverbindungspaare in turn each comprise two in the direction of each adjacent side wall portions projecting snap elements with a snap bolt which is connected via an elastically molded snap ridge with the Sohlenwandflansch, and two corresponding with these snap elements Schnappausnehmungen, each with two corresponding with the snap pin holding projections in the corresponding Have snap recesses, wherein in the final connection position, the snap pins can be latched above the mentioned retaining projections.

In addition, the snap bolts may be provided with a central through hole, each of which is closed in the final connection position on the side facing away from the retaining projection via a predetermined breaking point formed firing pin, said firing pin in the connecting position to realize a pull-out through the through hole into a corresponding Blind hole of the side wall portion is einschlagbar, so then the snap bolts are each firmly connected to the adjacent side wall part. The locking of the snap elements by means of the firing pin causes a pull-out protection for the plugged side wall part.

In a further embodiment, the side wall part and / or the sole wall flange adjoining in the connecting layer is provided with a sealing strip extending over the entire length, so that in the final connecting position of side wall part and trough part the connecting groove between the side wall part and the adjacent sole wall flange is sealed in a liquid-tight manner. hereby a leakage in the connecting region between the side wall part and the tub part is avoided.

For the final formation of a functional drainage channel it is not sufficient to set up the side wall parts on both sides of the trough part in the form described. Rather, a frame element for forming a frame for receiving a channel cover of the finished drainage channel must usually be placed on the side wall parts in addition in each case. For this purpose, the side wall part is provided with additional connecting elements for receiving and securing the aufzusetzenden Zargenelementes. In a concrete embodiment, the Zargenelement is placed by way of tilt mounting and secured in the final connection position by means of a snap connection.

The aufzusetzenden Zargenelement is usually a producible about by folding sheet metal profile with a substantially L-shaped cross-sectional profile, which serves to receive the aforementioned gutter cover. At this L-shaped receiving portion in the installation position, the inside of the respective adjacent side wall part cross-hook element is integrally formed.

The Zargenelement can be mounted in an advantageous manner by means of a simple tilt mounting, wherein the Zargenelement is first placed in a relation to the mounting position outwardly pivoted position on the upper Seitenwandflansch the side wall part, so that in this position, the hook elements engage over the inner edge of the upper Seitenwandflanschs. In the course of further assembly, the Zargenelement is then pivoted further inward, while meanwhile the hook elements each over on the side wall part molded slideways slide until it engages in its final latching position after final assembly, ie positionally correct positioning of the Zargenelementes.

In addition, on the frame element on the side facing away from the inside of the channel in the installation position, a projection is formed, which overlaps the upper edge of the respectively adjacent side wall part. In turn, pivotable securing straps are integrally formed on this projection, which can be folded in correlation-correct mounting of the frame in correlating outside receiving portions of the respective adjacent side wall part. As a result, a pull-out protection of Zargenelementes is realized such that the Zargenelement after installation of the drainage channel, ie after pouring the drainage channel in a surrounding the drainage gutter, in particular in-situ concrete, can not be deducted upwards, because the collapsed securing tabs peel off the Exclude Zargenelementes of the adjacent side wall part.

The respective correct position mounting the frame elements on the side wall parts is ensured, inter alia, that the intricate receiving pockets of the side wall parts for receiving the snap hook ensure that the snap hooks can only be inserted in the correct position mounting in the side wall parts and can be brought into engagement only in this position. In this position, it is ensured at the same time that the mentioned securing tabs for producing a trigger protection for the frame element in the corresponding receiving portions on the outside of the side wall part can be folded.

In a further embodiment of the plug-in channel, the individual drainage sections can also be securely connected to one another in the direction of impact by an imaginary extension of the sole contour of the drainage channel being formed on one abutment side of the drainage section of the trough part as a spring element, while on the other abutting side a sleeve element engaging under this spring element is formed. This connection technology in turn has the advantage that the tub parts can be cut to any length, because in this process at each separation point automatically a corresponding extension of the tub sole survives, so that the result is always a spring element is generated, always to the already mentioned sleeve element of subsequent drainage section is connectable.

In a further embodiment, the sleeve-spring principle described above is also realized in the joint area of the side wall flanges, so that they are cut to length analogously and can be connected to one another in any desired length in the joint area.

The invention will be explained in more detail with reference to an embodiment shown in the drawings, wherein the embodiment represents only one possible embodiment of the invention.

The perspective view in Fig. 33 shows a completely assembled plug-in channel 1, comprising a sole portion of the channel forming trough part 2, on both sides of the side wall parts 3, 3 'are placed in a manner to be explained in more detail. On the upper side wall flanges 4, 4 ' are on both sides even closer to be explained manner Zargenelemente 5, 5 'placed flush, which serve to receive a channel cover 6. Like also out Fig. 33 can be seen, but not further interest here, the side wall parts 3, 3 'are each provided with an external ribbing 7 to increase the load capacity of the channel. In addition, the trough part 2 has various connecting pieces 10 for the supply and discharge of guided in the plug-in channel 1 liquids.

According to Fig. 32 the plug-in channel 1 is constructed in such a multi-part, that the side wall parts 3, 3 'on the tub part 2 to form an at least approximately U-shaped drainage channel are attachable. In the unassembled form, the side wall parts 3, 3 'can be easily inserted into the trough part 2 and combined for the purpose of transport or storage into a unit 11, which can be stored and transported in a space-saving manner.

As shown in Fig. 1 to 3 the trough part 2 essentially consists of a sole 12, which is bordered on both sides by two sole wall flanges 13, 13 'in such a way that already the trough part 2 has a substantially U-shaped configuration according to FIG 4 to 6 has.

According to the views in FIGS. 2 and 3 the sole wall flanges 13, 13 'are each provided with latching projections 17, 18, 20 projecting in the direction of the side wall parts 3, 3' to be mounted, which are in each case designed in pairs plug elements of a total of three different catch guides and two snap connection pairs. Like also out Fig. 2 can be seen, both the locking projection pairs 17, 18, 20 of the catch guides as well as the snap element pairs 16, 16 'each symmetrical to a in Fig. 2 dash-dotted registered imaginary center line 14 arranged transversely to the longitudinal extent of the trough part 2. Thus, while the snap guides and the snap connections are realized by means of paired fasteners, the in Fig. 2 Sohlenwandflansch shown 13 'as the sole Solitärvorsprung additionally an index projection 15, which only serves to ensure that aufzusetzenden on the sole wall flanges 13, 13' side wall parts 3, 3 'can only be placed in the correct position, because only in this position, the trained as a cross projection Index projection 15 engages in a corresponding cross-like index recording 31 of the respective side wall part 3, 3 '.

The snap connection, which ultimately produces the connection, is provided by two snap-in elements 16, 16 'arranged in pairs symmetrically with respect to the center line 14 Fig. 2 realized. The catch guide pair forming the first catch guide is represented by the furthest inner latching projection 17, which is also formed in pairs. The second catching guide pair, which is therefore second in engagement during the joining process of the side wall part 3, 3 'on the trough part 2, is represented lying furthest outwards by the locking projection 18, which is likewise designed in pairs. The third catch guide is in turn by its turn further inward locking projection 20 in Fig. 2 shown. Also, this locking projection 20 is formed to form a fishing guide pair as described in pairs.

How out Fig. 2 clearly visible, the locking projections 17, 18, 20 have a different height, wherein the most projecting locking projection 17 of the first catching device first engages, the locking lug 18 formed in a shorter length of the second catching device secondly engages and finally the shortest latching projection 20 of the third catching guide due to this shorter training than the third device with the corresponding recesses 30 of the aufzusetzenden side wall part 3, 3 'into engagement.

Like also out Fig. 2 it can be seen, the first fishing guide pair is located furthest inside, so that the catch guide pair representing locking projections 17 each have the smallest distance and thus subject to the slightest tolerance deviations, so for this first joining operation between the aufzusetzenden side wall part 3, 3 'and the tub part 2, the highest Dimensional accuracy exists.

As in particular from Fig. 3 As can be seen, the latching projections 17, 18, 20 of the catch guides are each provided with hook elements which respectively point or act in different directions. This is because with the first catch guide, the relative movement of the side wall part 3, 3 'to the adjacent Seitenwandflansch 4, 4' is prevented in the longitudinal direction, while the second catch guide the relative movement transverse to the longitudinal direction of the adjacent Seitenwandflanschs 4, 4 'is prevented. Finally, with the third catch guide, the relative mobility of the side wall part 3, 3 'to be fitted on to the trough part 2 is prevented orthogonally to the two above-mentioned axes of mobility. Accordingly, the hook elements of Locking projections 17, 18 and 20 as well as in FIGS. 2 and 3 not shown recesses 27, 28, 30 of the adjacent side wall parts 3, 3 'formed differently.

The different design of the locking projections 17, 18, 20 is in particular in the perspective view according to Fig. 6 clearly visible. In this representation, the cross-like index projection 15 is clearly visible.

As shown in 4 and 5 showing the frontal views of the trough part 2, the trough parts 2 can be connected to each other by a sleeve-spring connection. In this case, the extended channel contour in the frontal view according Fig. 4 the spring element 21, while according to the other frontal view Fig. 5 a sleeve element 22 engaging under this spring element 21 is shown. As a result of this embodiment, the trough parts 2 can be approximately in accordance with the perspective view in FIG Fig. 2 be securely connected to each other in the joint area by the sleeve-spring connection described by the sleeve member 22 engages under the spring element 21 in the connecting position. If necessary, the sleeve-spring connection can be realized liquid-tight with the interposition of a not dargstellten here seal.

Fig. 7 to 14 show a side wall part 3 in all views. Fig. 7 shows the outside view of the side wall part 3, while Fig. 12 the side of the side wall part 3 facing the inner side of the plug-in channel 1 when mounted in the correct position. Fig. 8 shows the bottom of the side wall part 3 with the provided for connection to the tub part 2 recesses. 10 and 11 show the respective frontal views of the side wall part 3, wherein Fig. 10 the spring end of the side wall part 3, while Fig. 11 the socket end of the side wall part 3 shows. Here, too, a side spring element 23 protruding in the direction of the respective side wall element following in the impact direction is overlapped by a side sleeve element 24, so that a closed butt joint is formed between the side wall parts 3, 3 '.

As already mentioned, the side wall part 3 is provided on the outside with an external ribbing 7. The comparison of Figures 8 and 9 makes it clear that the top and bottom of the side wall part 3 are formed identically, so that the side wall part 3 can be connected to both the left and the right sole wall flange 13, 13 ', but in each case so that the plane inside 25 of the side wall part 3 always points inwards.

In Fig. 8 First, the Schnappausnehmungspaare 26, 26 'correlating with the snap projections 16, 16' can be seen, which make it clear that the snap elements 16, 16 'overlap the respective adjacent side wall part 3, 3' on the outside. Also will be in Fig. 8 clearly that the Schnappausnehmungen 26, 26 'are each formed in pairs.

In addition to the snap connection further recesses for receiving the locking projections 17, 18, 20 of the catch guides are formed on the side wall flanges 4, 4 '. With the locking projections 17 of the first fishing guide pair correlate to the imaginary center line 14 closest, inner recesses 27, with the locking projections 18 of the second catch guide the further outward recesses 28 of the second catch guide pair, while again further inside lying the recesses 30 of the third catch guide are arranged.

Incidentally, the side wall part 3, in turn, as a solitary, so not in pairs, trained index recording 31. The index holder 31 corresponds to the index projection 15 and, as already mentioned, ensures the correct lateral and correct mounting of the side wall part 3 on the adjoining sole wall flange 13.

FIGS. 13 and 14 show that in Fig. 7 to 12 shown side wall part 3 again in a perspective view of the inside of the side wall part 3 according to Fig. 13 and the outside of the side wall part 3 according to Fig. 14 ,

The formation of the snap connection between the side wall part 3, 3 'and the adjacent sole wall flange 13, 13' is in 15 to 20 each shown in a cross-sectional view, wherein Fig. 15 the side wall part 3 is still out of engagement with the snap element 16 of the adjoining sole wall flange 13, while the individual steps of the joining process shown in FIG Fig. 16 to 19 Finally, the cross-sectional view in Fig. 20 shows the closed snap connection between the side wall part 3 and the adjacent sole wall flange 13.

According to Fig. 15 the sole wall flange 13 has a snap element 16. The snap element 16 consists at least substantially of a resiliently integrally formed on the Sohlenwandflansch 13 snap-bar 39, which opens into a snap-in bolt 32. The snap bolt 32 is in turn provided with a central through hole 33, the one-sided is closed with a formed over a predetermined breaking point 34 firing pin 35.

As already mentioned, a snap recess 26, which is formed on the outer side of the side wall part 3, is integrally formed on the side wall part 3 to be connected. In this area, a cooperating with the snap pin 32 intended slide 36 is formed. Moreover, the side wall part 3 has a sealing groove 37 at its side wall flange 4 facing the adjoining sole wall flange 13, into which a seal 40 is inserted which, after the joining process has been completed, cooperates with a sealing wedge 41 projecting in the direction of the adjoining side wall part 3, which engages over the adjoining sole wall flange 13 in the direction of the aufzusetzenden side wall part 3 protrudes.

As soon as the side wall part 3 becomes increasingly engaged with the sole wall flange 13 in connection with the progressive engagement of the catch guides, the snap pin 32 slides along the slide track 36, during which sliding action the elastic snap tab 39 is increasingly deflected.

According to Fig. 17 Finally, the snap pin 32 reaches the end of the slide 36, in which state the deflection of the snap bar 39 has reached almost its maximum amplitude. In the progressing joining operation of the snap pin 32 reaches the end of the slide 36 finally the first edge of a subsequent to the slide 36 retaining projection 38 which is integrally formed in the region of the snap recess 26 to the side wall part 3, until finally in accordance with Fig. 19 the snap bolt 32 completely over the retaining projection 38 is pushed and in this state, the snap bar 39 from its deflected position in its original position according to Fig. 15 springs back and thereby pushes the snap bolt 32 on the retaining projection 37 to an applied position. In this position, the through hole 33 of the snap bolt 32 is aligned with an adjacent blind hole 42 of the side wall part third

According to Fig. 20 then the snap connection can be finally locked in that the firing pin 35 is driven by overcoming the predetermined breaking point 34 through the through hole 33 in the adjacent blind hole 42, so over the firing pin 35 a secure connection, in particular a pull-out protection of the side wall part 3 with the adjacent sole wall flange thirteenth of the trough part 2 of the plug-in channel 1 is formed.

In the latching position according to Fig. 20 Finally engages the sealing wedge 41 of the Sohlenwandflanschs 13 in the seal groove 37 of the adjacent side wall portion 3 and squeezes intended the inserted seal 40 to form a liquid-tight connection in this area.

The formation of the connection between side wall part 3 and sole wall flange 13 takes place in accordance with the design of the sole wall flange 13 FIGS. 21 to 26 analogous to the formation of the compound according to the 15 to 20 , It is different in the embodiment of the compound according to FIGS. 21 to 26 merely the formation of a sealing connection between the trough part 2 and the adjacent side wall part 3. The difference in this case is that instead of the formed on the Sohlenwandflansch 13 seal wedge 41 a sealing nozzle 43 is formed. Also in this embodiment, the adjacent side wall part 3 has a sealing groove 37. However, a seal 40 is not inserted in this seal groove 37, but rather on the Sohlenwandflansch 13 in the direction of the adjacent side wall part 3 projecting sealing nozzle 43 is formed, which in the closed connection according to FIGS. 25 and 26 engages the seal groove 37 to form a sealing connection.

Fig. 27 to 30 show the connection process of a Zargenelementes 5 with a side wall part 3 and with the upper in the mounting position Sohlenwandflansch 13 ', to which the Zargenelement 5 is placed by way of Kippmontage.

According to the cross-sectional view in FIG Fig. 27 is formed on the outside of the side wall part 3, a receiving pocket 44 into which engages in the direction of the receiving pocket 44 projecting hook member 45 of the Zargenelementes 5. The frame element 5 is a sheet-metal profile which can be produced by means of the fold-over and which initially has a substantially L-shaped receiving section 46 into which a channel cover can be inserted after proper mounting. At this L-shaped receiving element 46, the already mentioned hook element 45 is formed. On the inside of the plug-in channel 1 facing away from the outside of the Zargenelementes 5, a projection 47 is formed by way of a folded over.

According to Fig. 27 the frame member 5 is first placed in a relation to the mounting position pivoted outward position on the upper sole wall flange 13 '. The hook element 45 engages the sole wall flange as intended 13 on the inside. In the course of further assembly according to Fig. 28 to 30 Then the frame member 5 is gradually folded further inward, until finally the hook member 45 according to Fig. 30 finally locked in the receiving pocket 44. In addition, a securing tab 50 is integrally formed on the projection 47, which can be folded in the Verrastungsstellung of Zargenelementes 5 on the upper sole wall flange 13 'in a corresponding receiving portion 46 between the outer ribbing 7 of the side wall part 3, so that the securing tab 50 in this position, the Seitenwandflansch. 4 'engages. As a result, a pull-out protection for the frame element 5 is realized in the final mounting position.

The final mounting position of the frame member 5 on the side wall part 3 is also in the perspective view according to Fig. 7 shown. As can also be seen from this illustration, the above-mentioned securing tab 50 or, more precisely, several securing tab pairs 50 are formed on the projection 47 in such a way that the folded-in securing tabs 50 engage in the corresponding receiving portions 46 between the outer ribbing 7 and thus a pull-out protection for the frame member 5 represent. As shown in Fig. 31 one of the two securing tabs 50 of the tab pair is folded, while the other securing tab 50 is not yet folded.
