Drainage devices for draining surface water from large areas are already known and include an attachment frame for receiving a mostly lattice or rust-shaped cover, which is connected to a drain body

15 stands, via which it is connected to a floor drain so that surface water is discharged into a baseline. Large areas, such as car parking areas, pedestrian areas or shopping areas, are increasingly no longer covered with concrete or asphalt, but with cobblestones

20 or tiles laid out. Due to the static position of the drainage device, the position of the cover can often not be adapted to the contour of the paving stones or tiles. This affects the aesthetic effect of the pattern of the paving stones or tiles and that

25 Appearance of the surface area interrupted by the contour of the cover. Paving stones or tiles also have to be specially molded in order to be able to integrate the cover into a uniform surface.

30 In order to achieve a reduced impairment of the aesthetic effect of the pattern of the paving stones or tiles, the extension frame is attached to a circular flange, which is also in a circular trough-shaped extension Forming the drain body is stored flush. As a result, the cover adjusts itself by turning the flange accordingly, the corresponding contour of the paving stones or tiles. To ensure attachment, the rotary flange is provided with elongated holes on the edge, which are shaped in accordance with the circular shape of the flange.

Screws which are mounted in corresponding internal threads of the drain body reach through these elongated holes.

A disadvantage of such a drainage system is the limited rotation angle of the flange, since the partial circumference of the elongated holes is only limited for reasons of stability. On the other hand, the position of the cover cannot be varied. A corresponding shaping of the paving stones or tiles is therefore still necessary.

The invention has for its object to develop a drainage device of the type mentioned in such a way that the flange has two degrees of freedom and thus a displacement and an adjustment of the angle of rotation of the flange is made possible.

This object is achieved with regard to its device aspect by a drainage device with the features of claim 1 and by a method with the characterizing features of claim 18.

An important point of the invention is that the flange is mounted in a trough-shaped shape of the drain body, the area of which is substantially larger than the area of the flange. This makes it possible to change the position of the flange - and thus also the cover - in any direction. The flange can also be rotated as required. This makes it possible to have a variety of installation situations dominate. Furthermore, the trough-shaped shape and the flange are circular. The surface of the trough-shaped formation has recesses which are arranged radially at regular intervals. The number of notches is determined from the fact that the partial circumference between two adjacent notches on the outer edge may at most correspond to the partial circumference of the elongated holes in the flange. The partial circumference of the elongated holes is determined in such a way that no fractures occur on the outer edge of the flange despite the removal of material. In addition, the width of the notches is smaller than the width of the elongated holes. Due to this arrangement of the elongated holes in the flange and the slots on the surface of the drain body, it is ensured that regardless of the position and the angle of rotation of the flange, the position of the opening of an elongated hole and at least one opening of a slot matches. This ensures that the flange can be screwed to the drain body with the aid of a screw. A special screw is inserted through the slot into the slot and fastened using a rotary movement.

The surface of the flange preferably ends with a shoulder on the outer edge of the trough-shaped formation. This enables even laying of the paving stones or tiles in the area of the drainage device.

It is also expedient that the upper area of the extension frame is flush with the surface of the cover. This ensures an unimpeded drainage of surface water.

In a further embodiment of the invention, the height of the cover can be changed vertically. Such a height adjustment is achieved by inserting an intermediate frame under the top frame. Such an additional frame is simple adjustable and easy to assemble. In addition, several additional frames can be placed on top of each other, so that the height adjustment takes place in steps. The height adjustment of the cover should be such that after paving or tile laying work, the surface of the paving stones or tiles ends flush with the surface of the cover. This ensures optimal surface drainage.

The shoulder is preferably provided with a sealing collar on the outer edge of the trough-shaped formation. After applying a support layer under the tiles, e.g. Screed, the sealing sleeve is sealed with standard sealing compounds on the support layer in order to reliably integrate the drainage device into the sealing layer. As a result, in particular those lying under the floor

Structures, e.g. an underground car park, protected against the ingress of water.

Reinforcing ribs, which are flush with the surface of the trough-shaped formation, are preferably arranged in the drain body. The reinforcing ribs thus additionally support the flange when a force is exerted on the cover. In addition, a deformation of the drain body that occurs due to the action of a force on the cover is reduced. This prevents the drain body from breaking out of the floor covering and the sealing layer.

The drain body and the flange are preferably made of plastic, that is, from a relatively light, yet stable material that can be processed inexpensively. In addition, the lower part of the drain body can be quickly and easily shortened to the desired length during installation and inserted into a floor drain. Another significant advantage of using plastic is that Fixing the flange, special screws for plastic connections can be used in the slots on the surface of the trough-shaped formation.

The cover can preferably be made of stainless steel, cast iron or galvanized steel, that is to say of relatively non-slip materials.

Figure 6 is a plan view of a known embodiment of a ¹ dewatering device. In the following description, the same reference numbers are used for the same and equivalent parts.

1 shows a drainage device for point drainage of surface water in a sectional view. The drainage device consists of a drain body 1 which is inserted into a floor drain 13. The upper area of the drain body is designed as a circular and trough-shaped formation 5 and ends at the outer edge with a shoulder 10. On this paragraph 10, a sealing collar 12 is attached. A likewise circular flange 2 is stored within the trough-shaped formation 5, the diameter of which is smaller than the diameter of the trough-shaped formation 5. Thus, the flange 2 has two degrees of freedom, since it is rotatably and freely displaceable horizontally within the trough-shaped formation 5. The surface of the trough-shaped formation has slots 7 which run radially. At the outer edge of the flange there are mounting holes 6, which are designed as arc-shaped elongated holes in this embodiment. The surface of the flange has 6 depressions in the area of the fastening holes, so that a fixing device 8 is flush with the surface of the flange 2. In this version, screws are used to fix the flange. The injections 7 of the trough-shaped formation 5 are designed such that the thread of a screw can be turned into the material of the trough-shaped formation 5 with a corresponding rotation. The number of slots and the length of the elongated holes are selected such that the position of the opening of an elongated hole 6 and the opening of a slot 7 coincide regardless of the position of the flange. The arcuate elongated holes 6 are arranged along a single circle, the center of which is arranged in the center of the flange 2. On the flange 2, an attachment frame 4 is mounted, which is a cover 3 flush. The cover 3 can be firmly connected to the attachment frame 4 by means of a fastening device 14, for example a clamp or screw connection, or it can only rest in the attachment frame 4 due to its weight. The top frame 4 is shaped such that it occupies a flush surface with the cover 3.

Furthermore, the height of the support frame 4 is selected such that a flush surface with the cover 3 is achieved after the application of a support layer, for example screed, and a subsequent laying of tiles. This ensures optimal surface drainage and also prevents the risk of injury from stumbling.

The surface of the flange 2 is flush with the surface of the shoulder 10 of the trough-shaped formation 5. This ensures quick and easy laying of the tiles.

To explain the fastening of a flange 2 with a trough-shaped formation 5, reference is made to FIG. 2, which shows a partial section of the flange 2 and the trough-shaped formation 5 along the line II from FIG. 1. In this embodiment, the flange 2 is fastened with a screw which is inserted through an elongated hole in the flange 2 and then rotated into a slot 7 in the trough-shaped formation 5. The thread of the screw engages in the material of the trough-shaped formation 5. In this embodiment, the elongated holes are provided with milled-in depressions in order to ensure a flush surface of the flange 2. In the regions of the trough-shaped formation 5 in which there are no incisions 7 run, material savings are made, so that a reduction in weight and still sufficient strength in the area of the injections 7 is ensured. In Figure 3, the drainage device is shown in a plan view. The cover 3 is fitted in the top frame 4 and, in this embodiment, is fixedly connected to it by means of fastening devices 14. In a further embodiment, the cover 3 is firmly connected to the top frame 4 by means of clamping devices. In a further embodiment, the cover 3 can also rest on the attachment frame 4 without fastening devices 14. The top frame 4 is firmly connected to a flange 2. The outer edge of the flange 2 is provided with a plurality of elongated holes 6 which have a recess for receiving screw heads. The flange 2 is supported on the surface of a trough-shaped formation 5. This surface is provided with injections 7 which run radially. The number of incisions 7 and the length of the elongated holes β are chosen such that, when the flange 2 is in the center of the trough-shaped formation 5, as shown in this figure, the position of at least two openings of incisions and the opening of an elongated hole coincide. The fixation of the flange shown in this figure is ensured by means of screws which are inserted through the respective openings in the elongated holes 6 and are then screwed into the slots 7. On the shoulder 10 of the trough-shaped formation 5, a sealing sleeve 12 is attached by means of an adhesive connection. After applying a support layer, for example screed, the sealing sleeve 12 is sealed with this layer using commercially available sealing compounds in order to reliably integrate the drainage device into the support layer.

FIG. 4 shows the embodiment of a dewatering device with a rotated and displaced flange 2, which is explained in FIG. It can be seen that in the previously explained choice of the number of the slots 7 and the length of the partial circumference of the elongated holes 6, at least one opening a slot corresponds to an opening in an elongated hole - regardless of the angle of rotation and the position of the flange 2.

FIG. 5 shows a sectional view of a flange 2 with an additional frame 11. This intermediate frame 11 is shaped such that it can be placed between the top frame 4 and the flange 2. An advantage of this embodiment is that the height of the cover 3 and the top frame 4 can be changed quickly and easily by interposing different intermediate frames 11. This ensures adaptation to the respective height of the tiles or plaster layer.

FIG. 6 shows an embodiment of a drainage device belonging to the prior art. In this embodiment, the flange 2 also has elongated holes which are arranged on the outer edge. The flange 2 is fitted flush into the trough-shaped formation 5 of the drain body 1. Therefore, only the angle of rotation of the cover can be varied - and only to a limited extent. After setting the angle of rotation, the flange 2 is fixed with screws.
