Drainage channel

The invention relates to a drainage channel with a channel body that is approximately U-shaped in cross section, in particular a channel body made of plastic, which has two side walls that run at a distance from one another and have edge protection profiles that reinforce the upper longitudinal edges and are designed as supports for an upper cover of the channel body, such as a grate cover.

Such drainage channels are known. For example, G 88 04 073.9 describes a drainage channel that has a channel body made of polyester concrete. The longitudinal edges of the side walls of the channel body are each surrounded by a metal edge protection profile with an outer and inner leg. The edge protection profile is designed in such a way that it can be easily mounted on the longitudinal edges of the side walls of the channel body after the channel body has been completed.

The problem with this item is that it can hardly withstand strong lateral forces, such as those that can occur when driving over the installed drainage channel, and is therefore not suitable for a number of applications.

File: 983741 2/12 Description

A drainage channel called ACO DRAIN has become known from a company brochure from ACO Severin Ahlmann GmbH & Co. KG. The longitudinal edges of the side walls of the channel body are also equipped with removable edge protection profiles. In order to support the channel body when strong lateral forces occur, the edge protection profiles placed on each side wall are connected to one another by webs arranged transversely to the channel run.

Although this previously known object meets high load requirements, it is disadvantageous in that the webs running transversely to the channel path hinder the cleaning of the drainage channel.

The object of the present invention is therefore to create a drainage channel that meets high load requirements and is at the same time easy to clean.

This task is solved in a drainage channel of the type mentioned above in that the edge protection profiles are each a top frame that is mounted on a long edge of a side wall and fastened to it, and that removable spacers are arranged between the two top frames of the channel body.

With the invention, any lateral forces that may occur during installation of the drainage channel are absorbed by the removable spacers. After installation of the

File: 983741 3/12 Description

The spacers are removed from the drainage channel and the surface covering. Lateral forces that then occur, such as those that can occur when driving over the drainage channel, are absorbed by the cover placed on the edge protection profiles. When installed as intended, the drainage channel according to the invention therefore has no cross braces in the channel body that would hinder cleaning of the channel.

It is particularly advantageous if the attachment frames are each attached to the side wall of the channel body in a form-fitting manner, for example by means of a clip connection. In particular, the transport and production of the drainage channel according to the invention is made considerably easier as a result.

According to a further development of the invention, the widening of the longitudinal edges to form edge flanges protruding from the outside of the gutter ensures that the attachment frames are securely supported on the gutter body.

A particularly useful connection between the gutter body and the attachment frames is created by, on the one hand, the attachment frame engaging behind the edge flange with a holding section on the outside of the gutter and, on the other hand, recesses are provided in the side walls of the gutter body on the inside of the gutter, for example longitudinal grooves arranged at a distance from the longitudinal edges, into which the attachment frame engages with an inner section.

The spacers are advantageously designed as sheet metal profiles and are bent at their end sections facing the side walls of the gutter body when installed, preferably at right angles. With these end sections, they are firmly but removably held in tabs arranged on the top frames on the inside of the gutter. This arrangement enables the spacers to be installed and removed without any problems.

In an advantageous further development, the folded end sections of the spacers are each equipped with an "L"-shaped leg. These legs are designed in such a way that the spacers can be locked to the attachment frames in a simple manner by passing the "L"-shaped legs through the tabs and then moving the spacer in the longitudinal direction of the channel.

The spacers can be connected to the cover in a force-locking manner. After this connection has been loosened and the cover has been removed, the spacers can be detached from the attachment frames, which frees up the channel run for unhindered cleaning.

In order to anchor drainage channels firmly in the ground, they are often connected to a mortar bed or a concrete edging using special anchoring means. In order to facilitate the installation of such anchoring means, a further development according to the invention provides

File: 983741 5/12 Description

It is seen to be a good idea to equip the add-on frames with pre-drilled holes to which suitable anchoring devices, such as ground nails, can be attached if necessary.

In order to facilitate the insertion of the anchoring means mentioned, the edge flanges of the channel body in the areas that face the pre-drilled holes in the attachment frames when installed as intended are provided with weakened zones of thinned material thickness, which can easily be penetrated by the anchoring means when they are attached.

In a further advantageous development, it is provided that anchoring means are attached to the outside of the gutter on the top frames, which serve to secure the drainage channel in an embedding, such as a mortar bed. These anchoring means can be provided in addition to or instead of the aforementioned anchoring means to be inserted into pre-drilled holes in the top frames.

The anchoring means are conveniently held in tabs that are fixed but removable and are punched out at predetermined intervals on the outside of the gutter on the top frames. Tabs of this type are very reliable and particularly easy to manufacture.

To stabilize the drainage channel in a further advantageous development of the invention,

File: 983741 6/12 Description

It is proposed to equip the gutter body with reinforcing ribs protruding from the outside of the side walls.

Exemplary embodiments of the invention will be explained in more detail below with reference to the accompanying drawings. Schematic views show:

The gutter body 2 made of plastic comprises a gutter run 5 with a U-shaped cross-section, the two opposing side walls 6, 6' of which are each provided on the top - as shown in Fig. 3 - with horizontally running edge flanges 7 that extend outward from the gutter run. The edge flanges 7 serve to attach the edge protection profiles 3 in the manner described in more detail below.

On both sides, the gutter body 2 is provided with reinforcing ribs 9 that protrude from the outside of the gutter at predetermined, even intervals transversely to the longitudinal extension of the gutter body 2. The reinforcing ribs 9 are each firmly connected to a side wall 6, 6 ^λ , its edge flange 7, and a base plate 11 that delimits the gutter body 2 on the underside and additionally stabilizes the gutter body 2.

Furthermore, in the embodiment, the channel body 2 has features 12, 13 which are provided for connecting a supply line (12) or a drainage line (13) and can be drilled for this purpose, but are not of further interest here.

File: 983741 8/12 Description

The edge protection profiles 3 consist of two attachment frames 15, 15 \, each formed from a sheet metal blank, each provided with a support surface 16, 16 ^λ and a longitudinal side border 17, 17 ^λ for an upper cover - not shown in the figures - such as a grating.

The attachment frames 15, 15 ^�L are each placed on an edge flange 7, 7 ^�L of the gutter body 2 and fastened thereto by means of a clip connection.

For this purpose, on the one hand, an inner section 19 of the attachment frame 15, 15 \, which nestles against the side wall 6, 6 ^Λ of the channel 5 on the inside of the channel, interacts in a form-fitting manner with a longitudinal groove 21 arranged on the inside of the channel in the respective side wall 6, 6 \ at a distance from the edge flange 7, 7*, and on the other hand, an outer section 22 of the attachment frame 15, 15 ^Λ, which runs parallel to the inner section 19 on the outside of the channel - viewed in its longitudinal direction - is cut at predetermined intervals and partially bent to form holding sections 24. These holding sections 24 engage behind the edge flange 7 and thus, in conjunction with the inner section 19, create a firm but detachable connection between the attachment frame 15, 15 ^Λ and the channel body 2.

Instead of a longitudinal groove 21, recesses arranged at predetermined intervals in the side walls 6,6 ^�L of the channel 5 can also be provided, which are provided with corresponding

File: 983741 9/12 Description

corresponding features of the inner section 19 of the top frame 15,15 ^&Lgr; interact

The inner section 19 is provided with recesses at predetermined intervals in the longitudinal direction of the channel, which correspond to recesses 26 arranged in the side walls 6, 6 ^λ of the channel 5. These recesses 26 - possibly reinforced by metal inserts - are intended for the releasable locking of a cover by means of crossbars engaging in the recesses 26, as is described in detail in G 94 21 582.0, for example, but is not of further interest here.

In order to absorb lateral forces occurring during installation of the drainage channel 1, removable spacers 28 are provided between the side walls 6, 6 ^λ .

The spacers 28 are each formed from a sheet metal blank and are provided with a reinforcement section which extends over almost their entire longitudinal extent, with the exception of the end sections 32 facing the side walls 6, 6 ^', and is bent approximately at a right angle. The front end sections 32 of the spacers 28 are bent approximately at a right angle and are each provided with an "L"-shaped leg 34. The legs 34 serve to releasably lock the spacers 28 to the attachment frames 15, 15'.

For this purpose, fastening recesses are provided at predetermined intervals from the inner sections 19 of the attachment frames 15,15 ^�Lgr;

File: 983741 10/12 Description

cuts 29 which are provided with tabs 31 punched out on the inside of the channel. The tabs 31 are dimensioned in such a way that after the end sections 32 are pushed into the tabs 31, the legs 34 protrude from the underside of the tabs 31. By moving the spacer 28 in a direction parallel to the channel run 5, the spacer 28 can be locked in place in a simple manner. By proceeding in the opposite direction, the spacer 28 can be easily removed from the attachment frames 15, 15 ^&lgr;.

The spacers 28 are usually removed after the installation of the drainage channel 1. Any lateral forces that occur afterwards are absorbed by a cover (not shown) that is inserted into the attachment frames 15, 15 ^Λ . Alternatively, however, the spacer 28 can be left in the drainage channel 1 and only removed from it immediately before cleaning. In the latter case, it proves to be expedient to connect the spacer 28 to the cover in a force-fitting manner, which is also not shown here.

In particular, when the drainage channel is subjected to heavy loads, it is advantageous if these are accommodated in an additional stabilizing mortar bed 35 and firmly connected to it. Figs. 4 and 5 show various anchoring options for the drainage channel 1 according to the invention with such a mortar bed 35. 30

File: 983741 11/12 Description

In the embodiment according to Fig. 4, the attachment frames 15, 15 ^λ are each provided with holes 36 which are arranged in the support surface 16 of the attachment frame 15, 15 ^λ . Corresponding to the holes 36, weakened zones 37 with a thinned cross-section are provided in the edge flange 7, which can easily be penetrated by anchoring means such as ground nails 38 which are inserted into the holes 36 of the attachment frame 15, 15 ^λ . The holes 36 or the corresponding weakened zones 37 are designed in such a way that a ground nail 38 can be completely countersunk with its head 39 and thus does not impair the flat support of a cover on the support surfaces 16, 16' of the attachment frames 15, 15 ^λ .

After being secured to the drainage channel 1, the ground nail 38 can be bent upwards on the outside of the channel, which ensures a particularly good hold in the mortar bed 35.

In the embodiments shown in Fig. 5, anchoring means are arranged on the outside of the gutter on the attachment frame 15, 15 ^λ in the area of the outer section 22. For this purpose, the outer sections 22 of the attachment frames 15, 15 ^x are provided with holding tabs 41, 41 ^λ punched out on the outside of the gutter. While the holding tab shown in Fig. 5a is arranged in a vertical section of the outer section 22, the holding tab 41 ^λ shown in Fig. 5b is provided in the area of a holding section 24 which serves to fix the attachment frame 15, 15 ^λ to the edge flange 7 of the gutter run 5.

File: 983741 12/12 Description

As can be seen in Fig. 1, flat retaining profiles 43, 44, each provided with an elongated hole 45, can be used as anchoring means for the embodiment shown in Fig. 5a. The cross-section of the retaining profiles 43, 44 is adapted to the cross-sectional openings of the punched-out tabs 41, ^41λ and is easily passed through the tabs 41 and ^41λ for fastening to the attachment frames 15, ^15λ . After fastening to the attachment frame 15, the retaining profile 43 is bent up on the outside of the gutter for stable anchoring in a mortar bed 35 - similar to the ground nail 38.

In contrast, the holding profile 44 shown in Fig. 5b has a slightly curved configuration, the curvature of which is selected such that, on the one hand, the holding profile 44 can be passed through the tab 41 * without any problems and, on the other hand, a secure hold in a mortar bed 35 is ensured, whereby bending the holding profile 44 is unnecessary.

The fastening means shown in Fig. 5 can be used instead of or in addition to the fastening means shown in Fig. 4 for anchoring the drainage channel 1 in a mortar bed 35.
