The frame has on its upper edge a folded edge (6), to which an inner cheek (8) and a vertically projecting from this support surface (7) connect. Below the bearing surface (7) is on the frame a U-shaped, the support surface engages under support profile (11) formed, whose first U-flank (10) with the support surface (7) is connected and the second U-flank (12) the gutter wall is applied. In addition, load cross members (15) can cause additional transverse stiffening of the drainage channel.

Description

The invention relates to a drainage channel with a two longitudinal, with a gutter sole interconnected Rinnenwandungen having gutter body, and with a frame for Auflagerung a the gutter body cross gutter cover, the frame along a top edge forms a fold, to which an inner cheek and one of this connect substantially vertically protruding support surface.

Such a drainage channel is from the DE 195 11 206 A1 previously known. In this case, the frame is designed as an upper gutter part in such a way that frame side walls slide along the side walls of the gutter body. To ensure a height adjustability of the frame, double-tube guide adjustment elements are arranged within the channel body in the edge regions and against the bottom of the channel body. The adjusting elements are above, that is height adjustable by means of holes in the frame and / or a top frame, by means of screw thread. One of this frame recorded and laterally fixed cover grate absorbs loading forces and directs them over several adjusting elements on the continuous bottom of the channel body. The basic idea of the previously known drainage channel exists in that at the bottom of a closed floor group, which ultimately forms the channel body, is provided. On this floor group a height-adjustable frame is placed by means of telescopic adjustment.

In addition is from the EP 2 851 477 A1 a drainage channel with a cross-section approximately U- or box-shaped gutter body made of sheet metal for embedding in a foundation as well as a the open longitudinal side of the channel body covering grate previously known. The gutter body is reinforced by means of its longitudinal extent laterally arranged support body for transmitting vertically acting on the rust pressure forces on a arranged below the support body foundation in its load capacity. Incidentally, the gutter body can additionally be stiffened by means of transverse webs arranged between the side walls of the gutter body transversely to the longitudinal extent of the gutter body. The transverse webs are locked with provided on the side walls of the gutter body recesses or hooked in the recesses.

A comparable stiffening of the gutter body by transverse to the longitudinal extent of the gutter usable toggle body is also from the DE 10 2007 010 073 A1 previously known.

Based on this prior art, the invention is based on the object by additional features a further stiffening of the gutter body, but also the gutter body associated frame, purely constructive effect to the extended capacity and extended service life for the extended To achieve drainage channel according to the invention.

This is achieved by the fact that the upper edge of the channel wall of the drainage channel has a frame, which along its upper edge forms a folded edge. At this Umkantung joins an inner cheek, at which the side of a gutter cover can create. Vertically to the inner cheek then a support surface 7 is formed, on which the weight of the gutter cover is supported. According to the invention, this support surface in turn to engage under a U-shaped support profile, which supports the support surface with a first U-flank by the U-shaped support profile is supported with its remote from the support surface, second U-flank on the Rinnenwandung , Thus, a derivation of weight forces of the gutter cover in the gutter wall. At the same time wins the support surface and the overall construction in comparison to the prior art despite low material usage of dimensional stability.

First, such a solution can be made as a one-piece combination of frame and gutter body by the described Umkantungen be completed directly with the material of the gutter body.

Alternatively, however, it is also intended to realize the frame as Aufsteckzarge in which the folded edge is prepared for receiving the free upper edge of the Rinnenwandungen. The folded edges are then bent over by 180 ° so that two material layers of the frame form parallel flanks. In this Umkantung then the upper edge of the channel is inserted and fixed positively and non-positively. This can be done by clamping, crimping, clinching, screwing, riveting and other possible types of connection.

In the latter case, the upper edge of the Rinnenwandung is reinforced on both sides by the folded edges and stiffened or the upper edge of the Rinnenwandung is protected by this upper edge cross-fold.

In both alternatives, the edge of the frame is adjoined by a support surface projecting in the direction of the channel inside, on which a cover grate of the drainage channel can be supported when used as intended. This bearing surface is bent downwards on its side facing the gutter inside end edge, in that a vertical flange arranged vertically in the installed position adjoins a first U-flank, and subsequently adjoins a U-shaped support profile fitting with a second U-flank on the channel wall.

This is caused by the multiple forming to form the folds of the frame first a stiffening of the frame itself. Incidentally, compressive forces introduced via the contact surface are at least partially received via the first U-flank adjoining the contact surface, are drawn downwards and finally introduced via the but after bending into a second U-flank, which in turn is supported on the side walls, so that the forces are introduced in these reinforced by the second U-flank sidewall area. Accordingly, compressive forces introduced via the gutter cover into the frame need not be absorbed by it alone, as well as not alone by the adjacent gutter walls, but rather they are taken together and derived in the underlying foundation under the drainage channel. As a result, the drainage channel according to the invention can either be exposed to greater loads or produced less materially.

In an advantageous embodiment, the abutment flange of the Aufsteckzarge be suitably connected to the adjacent Rinnenwandung. In this context, in particular the use of a riveted joint has proven itself.

In an advantageous development of the solution according to the invention, the frame according to the invention is provided in the region of the inside of the gutter of the gutter body facing inner cheek and / or in the region of the first U-flank with recesses, in particular for fixing a gutter cover. The fixation of the gutter cover succeeds in a simple manner, that are approximately connected in the direction of the recesses engaging elements with the Aufsteckzarge and this thus against displacement in Secured longitudinally, so the corresponding covers are secured in their correct relative position to Aufsteckzarge. In another advantageous development releasable fasteners are used in this context, so that the gutter cover can be removed if necessary from the drainage channel, about to clean or otherwise to maintain, or if necessary to replace the gutter cover can.

In a further improved embodiment, the gutter body of the drainage channel can be stiffened by means of transversely to the longitudinal direction of the channel body usable load cross-members. This has the advantage that the load crosspieces stiffen the gutter body in the transverse direction, in particular to prevent possible buckling or possible indentations of the lateral gutter walls of the gutter body, so that in this way the load capacity of the gutter body of the drainage channel according to the invention is further improved.

In a concrete embodiment, the load cross members are each arranged directly below the support flange of the Aufsteckzarge, so that the introduced via the gutter cover forces can be taken in each case by the load cross members and derived to the outside to the gutter walls.

In concrete embodiment, the load cross members are each designed as a downwardly open box sections, whereby a material savings compared to closed box bodies is achieved because a lower cover of the box section would make no significant contribution to the stiffening more.

In a further improved embodiment, the load traverses are designed such that the end walls of the box sections are not directly connected to the adjacent side walls of the box section, but rather on both sides of the end walls is formed a respective insertion slot. As a result, a further saving of material is initially achieved. Incidentally, the channel walls of the channel body are in the direction of the channel interior of the channel body projecting Einstecklaschen provided such that the end walls of the load traverses in each case in the region between the projecting in the direction of the channel interior insertion tabs and the Rinnenwandungen are inserted.

In the case of a Aufsteckzarge it is also particularly advantageous if the load traverses are then each immediately below the Abstützflansches the Aufsteckzarge, thus reach under this, so about about a mounted on the Aufsteckzarge groove cover forces are discharged to the outside of the gutter walls of the gutter body.

The gutter body itself, in particular its gutter walls and its gutter sole, are each provided with inlet openings distributed over the gutter body, so that not only through the gutter cover introduced surface water, but possibly also in the gutter environment entering leachate entering the gutter body and can be discharged through this.

In an advantageous embodiment, the gutter body of the drainage channel and / or the load cross members are / are as folded sheet metal blanks, d. H. made of a comparatively light and therefore also easier to transport material produced.

In this a section is marked, which is the essential part of the FIG. 2 corresponds, which is shown next to it. Coming from a trough sole 4, the gutter wall 3 begins after a substantially right-angled fold, which, in turn, merges into an inner cheek 8 on the upper edge of the drainage gutter 1 formed thereby, following a 180 ° turn-around 6, which laterally contact the gutter cover when the gutter cover is inserted would. From this inner cheek 8 is offset by the thickness of a gutter cover not further described here relative to the upper edge down from a support surface 7, below which a support section 11 is first followed by a first U-flank 10. A second U-flank 12 of the support section 11 contacts the channel wall 3 and initiates the weight forces acting on the channel cover in this.

FIG. 3 shows an alternative drainage channel 1 in an embodiment with a Aufsteckzarge in a perspective view in an exploded view. In this embodiment, a frame 5, 5 'in the form of a Aufsteckzarge be plugged onto the upper edges of the Rinnenwandungen 3, 3', although, if necessary, can be positively and non-positively connected to the Rinnenwandung, but not directly formed. For transverse reinforcement of the channel body 2, additional load cross members 15 can be inserted transversely to the longitudinal extension of the channel body 2 into the channel body 2. In this case, the load cross members 15 are each formed as a downwardly open box sections and each upper side closed by a closed support surface 16, on both sides of the downwardly open side walls 17, 17 'connect, wherein the box profile frontally of the end walls 20, 20' is limited , In the transition region between the end walls 20, 20 'and the side walls 17, 17' in each case a Einsteckschlitz 21, 21 'is arranged.

The gutter body 2 is on both sides in the region of the gutter walls 3, 3 'respectively with the end walls 20, 20' of the load cross members 15 corresponding, projecting in the direction of the channel interior of the gutter body 2 Einstecklaschen 22, 22 'provided. Accordingly, the load cross members 15 can be connected to the channel body 2 as intended such that the end walls 20, 20 'in the area between the Einstecklaschen 22, 22' and the adjacent Rinnenwandung 3, 3 'are inserted, so that the load cross members 15 each intended transverse to Longitudinal extent of the channel body 2 in the channel body 2 are arranged.

Like also out FIG. 3 can be seen, the gutter body 2 is distributed over its circumference, ie in the region of the side walls 3, 3 'and the trough sole 4, respectively provided with inlet openings 24, so that approximately in the vicinity of the channel body 2 seepage infiltrated water via the inlet openings 24 in the channel body 2 arrive and can be removed by this intended.

The Aufsteckzargen 5, 5 'exist as shown in FIG FIG. 4 , which shows the drainage channel 1 in a mounted position in a perspective view, in each case of a when installed as intended, the upper edge of the channel walls 3, 3 'cross edge 6, 6', an adjoining inner cheek 8, a support surface 7 and an underlying support section 11th In this case, the area of the inner cheek 8 in the installed position passes through a right-angled fold in the horizontal in the mounting position bearing surface 7. On this support surface 7 a not shown in the drawings channel cover is intended to. In the way of a further, at least substantially right-angled fold on the side facing away in the installation position of the adjacent Rinnenwandung 3 or 3 'longitudinal edge of the support surface 7, the support surface 7 is in a U-shaped support section 11, whose first U-flank 10 directly to the Support surface 7 is fixed and the second U-flank 12 is supported on the adjacent side wall 3 or 3 '.

In this case, the Aufsteckzargen 5, 5 'are each provided with recesses 14, both in the interior of the channel interior facing the inner cheek 8, as well as in the region of the support surface 7 and in the region of the first U-flank 10. These recesses 14 are usually used for the correct fixing and fixing a in the Aufsteckzarge 5, 5 'to be used gutter cover, which is not shown in the drawing.

In this case, the load cross members 15 each engage under the illustration in FIG Fig. 4 when properly mounted the Abstützflansche 11 of the intended purpose on the upper edge of the Rinnenwandungen 3, 3 'seated Aufsteckzargen 5, 5', so that the Aufsteckzargen 5, 5 'each additionally supported on the load traverses 15.

FIG. 5 shows the drainage channel 1 in a plan view. In this case, a respective Aufsteckzarge 5, 5 'attached to the upper edges of the Rinnenwandungen 3, 3'.

FIG. 6 shows along the in FIG. 5 Registered section line a cross section through the channel body 2 of the drainage channel. 1

FIG. 7 shows an in FIG. 6 with VII designated detail of the cross-sectional view, in particular concerning the attachment of the frame 5 formed here as Aufsteckzarge. As shown in FIG. 7 engages in the mounted position, a folded edge 6, the upper edge of the groove wall 3 ', wherein adjoins the folded edge 6 on one of the gutter inside facing inner cheek 8 via a right-angled edge of the support surface 7 for a groove cover, not shown. Along its side remote from the Rinnenwandung 3 'longitudinal edge is followed by a further right-angled edge, followed in turn by a U-shaped support profile 11 is connected. This comprises a first U-flank 10, as well as a second U-flank 12 which extends horizontally in the installation position and rests parallel on the channel wall 3 '. In this case, the second U-flank 12 is firmly connected by means of a rivet connection 13 with the adjacent channel wall 3 '.

In addition, as already stated, immediately below the support profile 11, the load cross member 15 is arranged such that the support surface 16 of the load cross member 15 engages under the support profile 11. In this case, the load cross member 15 as shown in FIG FIG. 7 thereby connected to the gutter body 2 of the drainage channel 1, that the end wall 20 in each case in the intermediate region between a relative to the gutter walls 3, 3 'projecting Inserting tab 22, 22 'is inserted on both sides, so that the load cross member 15 as intended in accordance with the illustration in FIG. 5 is arranged transversely to the longitudinal extent of the drainage channel 1 immediately below the support section 11. In this case, the end walls 20, 20 'of the load cross member 15 are each dimensioned such that the end walls 20, 20' in each case protrude beyond the insertion tabs 22, 22 'on the underside in such a way that the supernatant 23 of the end wall 20 formed to that extent acts directly on the adjacent channel wall 3'. is applied.

As a result, therefore, the folded edge 6 of the frame 5, 5 'causes a stiffening and edge protection for the upper edge of the Rinnenwandungen 3, 3'. Furthermore, the frame 5, 5 'on both sides each a support surface 7 for a not shown in the drawing channel cover ready. In this case, pressure forces introduced via the gutter cover are in each case discharged downward via the first U-flank 10, this first U-flank 10 of the support profile 11 via a sole of the support profile 11 and the second U-flank 12 on the gutter wall 3, 3 '. is supported. As a result, accordingly, the introduced compressive forces via the gutter walls 3, 3 'downwards either in the ground or in a foundation that crosses under the drainage channel 1 are diverted as intended. In this case, the abutment flange 12 causes an additional reinforcement and reinforcement in this area in the area of the introduction of force into the respectively adjacent channel walls 3 and / or 3 '. Incidentally, the execution of the frame 5, 5 'in multiple folded over form a stiffening of the frame 5, 5' in itself.

In addition, the support profile 11 is engaged in each case by the support surface 16 of a load cross member 15, via which also a load transfer can take place. Here, too, the protrusion 23, which adjoins the gutter walls 3 and / or 3 'directly, of the end walls 20, 20' of the load crossmember 15 brings about additional reinforcement and stiffening. In addition, the load crossmember 15 causes a transverse reinforcement of the channel body 2 in total.

Thus, a drainage channel 1 is described above, which can be produced from a gutter body, a frame and, if necessary, one or more load cross members by mating or joining the items or directly in one piece by edge and bend, whereby by the interaction and the structural design of the above-mentioned items a total of a more stable and resilient drainage channel is generated, so that the items can be made, for example, as a comparatively thin-walled blanks without this would suffer from the capacity of the drainage channel.
