EP2904162B1 - Drainage channel with a channel body and a cover - Google Patents

Description

The invention relates to a drainage channel with a channel body and a cover according to the preamble of claim 1.

Drainage channels with a cover are widely known. A major problem with such items is that on the one hand must be present from the production cost-favorable design, but on the other hand, the laying and assembly should be easy. In addition, the resilience of the drainage channel with its cover is an essential criterion, as they are laid in streets and squares and run over.

If the drainage channel and the cover are made of a correspondingly stable material and the two parts are screwed together, so does a high-strength structure that can withstand higher loads, however, the manufacturing costs and the work involved in installation in the ground considerably. Furthermore, the manufacturing and storage costs are high.

The EP 2 468 969 A2 describes a trough system for removing water in road construction and the like. In this case, a channel body is covered with a variety of cover units modular. In order to provide a positioning of cover units on the gutter body in the longitudinal direction of the gutter body, the gutter body has top side in side walls pin receptacles, can engage in the pins of the cover.

Further drainage channels are from the WO 2001/150447 A1 as well as from the US 5,181,793 known.

The invention is based on the object to show a drainage channel with a gutter body of the type mentioned in that with a simple design and low cost of manufacture and Storage during installation in the ground yet high strength is achieved.

This object is achieved by a drainage channel according to claim 1.

In particular, this object is achieved by a drainage channel having a channel body and a cover characterized in that the channel body and the cover seen in a longitudinal direction of the channel body continuously having first engagement means on the channel body and second engagement means on the cover, which upper edges of the channel body over the entire length together connect tensile strength to each other transversely to the longitudinal direction. This creates a closed box construction, which on the one hand is easy to manufacture and assemble, but on the other hand has a high resistance to loads.

The first engagement means are in this case arranged in different arrangement patterns on the gutter body such that different types of covers with a (single) gutter body can be used. In this way, from the stability and the design ago various covers can be used, what hitherto various gutters were necessary, which reduces the cost of production and storage.

The first engaging means comprise teeth on the gutter body, the second engaging means comprise strips on the cover (or vice versa) which engage with each other. After the engagement means are provided over the entire length of the drainage channel, the stability of the individual teeth (and strips) can be relatively low. Simply by the amount of interventional devices (or on teeth), the necessary stability is guaranteed.

The first engagement means are arranged in different height levels of the gutter body. Of course, this applies in particular if - as mentioned above - various covers with one and the same gutter body to be used. In addition, however, it is possible to design the covers in such a way that they are connected to the channel body several times, that is to say in the different height levels, or rest there. This can further increase the load capacity of the drainage channel.

In a first embodiment of the invention, the second engagement means are attached to the cover at a bottom of edge gutter pads. This results in a very simple construction.

The second engagement means may alternatively (or additionally) be formed as lower edges of peripheral side rails of the cover, so that a structural element of the cover is used, which is present anyway (for reasons of stability).

Furthermore, stop devices are preferably provided which limit a displacement of the cover relative to the channel body in its longitudinal direction, so that even with loads of the cover in a longitudinal direction of the drainage channel (eg when braking or accelerating a roll over vehicle), the cover sits substantially immovable on the gutter body ,

Furthermore, it is advantageous if the first engagement means with the second engagement means are cooperatively formed so as to limit a displacement of the cover to the gutter body in its longitudinal direction, as do the above-mentioned stop means alternatively or additionally.

The entire construction is then particularly easy to produce and (due to low weight) also easy to install when the gutter body is designed as a plastic injection molded part. The same applies to the cover, which can also be designed as a plastic injection molded part.

In the following description, the same reference numerals are used for the same and like parts.

The in the Fig. 1 and 2 shown drainage channel comprises a channel body 11 and a cover 20. Both parts are formed as plastic injection molded parts.

At upper edges 12, 12 'of the channel body 11, upper teeth 13, 13' are provided, which form a row of teeth running over the entire length of the channel body. These teeth 13, 13 'come with strips 24 into engagement, which are provided on an underside of a gutter support 21, 21' of the cover 20 and stabilize them. The gutter supports 21, 21 'protrude from longitudinal members 22, 22' outwards. When the cover 20, the in Fig. 2 is shown is placed on the channel body 11, so the strips 24 with the upper teeth 13, 13 'into engagement, so that a tensile connection between the upper edges 12, 12' of the channel body (and at the same time a shear-resistant connection) is formed , Thus, in the assembled state of the drainage channel is a completely closed box profile, which has a high stability.

The intervention of last 24, which in Fig. 2 shown, with the upper teeth 13, 13 'of the channel body 11 provides not only the described tensile strength connection, but it is the cover 20 as seen in the longitudinal direction of the drainage channel 10 secured on the gutter body 11. This backup takes place over the entire length of the drainage channel 10, so that a very high stability is ensured.

In Fig. 1 is further shown that a second row of teeth, namely lower teeth 14, 14 'are provided on the channel body 11. These lower teeth 14, 14 'come with lower edges 23, 23' of longitudinal members 22, 22 'of a differently shaped cover 20 in combination, as shown in the 3 and 4 is shown. The cover 20 shown there is formed from sheet steel. Trough supports 21, 21 'of the cover 20 after the 3 and 4 lie on the upper teeth 13, 13 ', wherein here again the continuous attachment of the rows of teeth 13, 13' ensures sufficient stability under vertical load. In addition, the cover 20 rests twice, once with its gutter pads 21, 21 'on the upper teeth 13, 13' and once with the side rails 22, 22 'in the region of the lower teeth 14, 14', so that increased stability over Vertical loads is ensured. To look at the cover Fig. 3/4 a displacement in the longitudinal direction of the drainage channel 10 to stopper protrusions 15, 15 'are provided at the ends of the channel body 11, which engage with end edges 25, 25' of the cover 20 (see in particular FIG Fig. 4 ) When the cover 20 in the longitudinal direction of the drainage channel 10 z. B. is moved by a braking or accelerating vehicle.

From the above, it can be seen that the above-mentioned high-tensile connection between the upper edges 12, 12 'is ensured even when a differently shaped cover 20 (as in FIGS 3 and 4 shown) together with the channel body 11 is used.
