From 1 apparent embodiment of an inventive arrangement comprises a bottom plate 1 and a drain device. The drainage device essentially comprises an odor trap unit 2 with an inner part 3 and an outer part 4 , a first fastening part 5 , a plate made of sheet metal 6 , a second fastening part 7 , a piece of pipe 8th with a flange 9 and a drain pot 10 , The drain pot 10 is in the illustrated embodiment with a drain pipe 11 connected.

In particular, the sectional view according to 2 is removable, that the odor trap unit 2 constructed in a conventional manner siphon-like. The inner part 3 extends in the form of a downwardly open pipe socket in the outer part 4 Bottom cupped and overflowed at the top.

2 and 3 can also be seen that the first fastening part 5 on its outside an external thread 12 whereas the second attachment part 7 on its inside an internal thread 13 having. In 2 and in 3 stand the internal thread 13 and the external thread 12 engaged with each other.

Furthermore, both can be 1 as well as 2 and 3 see that the second attachment part 7 on its outside a lip seal 14 having. The lip seal 14 forming sealing material extends, as can be seen 3 can be seen in detail, on the outside of the second fastening part 7 upwards, leaving the upper edge of the second attachment part 7 also from a circumferential seal 15 is covered. How out 3 It can also be seen that in the assembled state of the drain device, this upper circumferential seal 15 on the underside of the sheet designed as a sheet metal 6 in a subarea.

The bottom plate 1 has an opening in the illustrated embodiment 16 with a substantially square outline. Instead of an opening 16 However, with a square outline it is quite possible to choose an opening with a circular outline or a differently shaped opening.

Furthermore, the sheet designed as a plate 6 a provided in the illustrated embodiment with a circular outline opening 17 on. Also this opening 17 may have different outlines. Furthermore, this is the opening 17 surrounding edge of the plate 6 bent slightly downwards. But there is also the possibility that the edge is flat.

The first attachment part 5 points, as for example 1 and 3 it can be seen, an upper, radially outwardly extending flange 18 on, in the assembled state of the drain device on the slightly bent-down edge around the opening 17 the plate 6 rests. The edge is thus adapted in particular to the shape of the flange. In particular from 3 it can be seen that between the bottom of the flange 18 of the first attachment part 5 and the top of the plate 6 in the region of the slightly downwardly bent edge, in particular a seal designed as an O-ring 19 is provided, which is the first fastening part 5 opposite the plate 6 seals. Through the seal 19 and the circumferential seal 15 thus becomes the plate 6 from above or from below the first fastening part 5 and the second attachment part 7 sealed.

Here, in the illustrated embodiment, the drain pot 10 an upper radially outwardly extending flange 21 on top of which the disc-shaped seal 20 can rest. In particular, the disc-shaped seal 20 with the flange 21 of the drain pot to be screwed (see 2 ). In 2 is still a part of the soil, namely a screed layer 22 shown, in which the drainage device is at least partially introduced. In particular, this seals the disc-shaped seal 20 the lower part of the drainage device from the bottom of the screed layer.

In 2 are the drain pot 10 and the drainpipe 11 dashed lines. This dashed representation of the drain pot is intended to illustrate that instead of the drain pot 10 also directly a drain pipe can be used, in the example, the second attachment part 7 with its outer lip seal 14 is inserted.

In the illustrated embodiment, the drain pot is first for mounting the drain device according to the invention or to achieve the inventive arrangement 10 installed and with one or more drainpipes 11 connected. Then, in the opening of the pipe socket 8th introduced, which extends through the opening through into the region of the seal 20 , or to the upper edge of the drain pot 10 , After that, it will be down to the bottom of the flange 9 of the pipe section 8th a screed layer 22 applied to the ground.

After drying the screed layer 22 becomes the second attachment part 7 in the pipe section 8th brought in. Due to the lip seal 14 This results in a comparatively firm and secure connection between the second fastening part 7 and pipe section 8th ,

Then it is attached to the underside of the bottom plate 1 the plate 6 glued so that the two openings 16 . 17 correspond with each other. Alternatively, the plate 5 even before mounting to the underside of the bottom plate 1 have been glued, especially to stabilize them. After that, the bottom plate 1 on the screed layer 22 such in the area of the flange 9 applied that to the openings 16 . 17 with the corresponding opening in the screed layer or with the pipe section 8th correspond or are aligned.

Subsequently, the first fastening part 5 through the opening 16 in the bottom plate 1 through into the second fastening part 7 introduced and screwed into this. By screwing the fasteners 5 and 7 together, the upper flange 18 of the first attachment part 5 from the top against the plate 6 pressed, whereas the upper, with the circumferential seal 15 provided edge of the second fastening part 7 from below against the plate 6 is pressed. This creates a secure and tight connection between the plate 6 and the fastening part 5 . 7 ,

Then it is also from above through the opening 16 the odor trap unit 2 in the first attachment part 5 inserted. The first attachment part 5 indicates how this particular out 3 it can be seen, an arranged in its upper region inner pad 23 for the smell closure unit 2 on. For this purpose, the outer part 4 the odor trap unit 2 with a radially outwardly extending edge 24 equipped on the pad 23 can rest. On this edge 24 of the outer part 4 There is also an outwardly extending edge 25 of the inner part 3 on. Like also out 3 is apparent is in the upper edge 25 of the inner part 3 the odor trap unit 2 a groove provided in which an o-ring 26 is arranged, which is the odor trap unit 2 opposite the inner edge of the first attachment part 5 seals.

After inserting the odor trap unit 2 be at the in 1 to 3 illustrated embodiment in the opening 16 the bottom plate 1 three frames 27 used, which also have a square outline and comparatively accurate in the opening 16 fit. On this frame 27 can a rust 28 be hung up. It is inventively possible, more or less frame 27 to use. For example, a high frame could 27 used, which has the same height as the stacked frame 27 ,

In the embodiment according to 4 to 6 the same parts are provided with the same reference numerals as in the embodiment according to FIG 1 to 3 , The essential difference of these embodiments is that the embodiment according to 4 to 6 on the separate second attachment part 7 waived. Rather, it forms, for example 4 apparent drain pot 29 in this embodiment, the second attachment part. For this purpose, the drain pot 29 an internal thread 30 on, in which the external thread 12 of the first attachment part 5 can be screwed. In the 4 to 6 The illustrated embodiment thus represents a simplified embodiment in which some parts can be dispensed with. The drain device according to this embodiment further comprises an annular seal 31 placed on the top of the drain pot 29 is attached and in the assembled state of the drain device the drain pot 29 against the underside of the plate 6 seals (see 6 ).

Further different from the first embodiment, in the second embodiment, the plate 6 in the area around her opening 17 does not have a slightly downward edge. Rather, the edge is around the opening 17 in the plane of the plate 6 so that also the upper flange 18 of the first attachment part 5 is shaped slightly differently than in the first embodiment. In particular, the flange 18 in the second embodiment according to 4 to 6 substantially perpendicular to the vertical extent of the first attachment portion 5 trained (see for example 6 ).

Another difference is that in the embodiment according to FIG 4 to 6 the bottom plate in the opening 16 a paragraph 32 has, on which the rust 28 can rest. In this embodiment is thus on the inserted frame 27 waived. Of course, it is quite possible according to the invention to have such a design with a shoulder in the opening 16 the bottom plate 1 also in the first embodiment with a separate second attachment part 7 to use. Furthermore, of course, there is also the possibility of a substantially rectangular upper flange 18 of the first attachment part, as in the embodiment according to 4 to 6 is provided, also in the first embodiment according to
