There is the possibility that one of the drainage openings 3, 4 is provided with a blind plug during assembly according to local requirements and the other of the drainage openings 3, 4 is connected to a drain line 5.

The drain housing 1 is mounted before the application of screed on the bare floor and connected to a drain pipe. Subsequently, the screed is applied to the subfloor, so that the drain housing 1 is at least partially surrounded by the screed. Subsequently, the soil including the already mounted drainage parts is sealed, in particular provided with a composite seal.

The drain housing 1 is surrounded by a collar 6 which has a plurality of openings 7. The openings 7 can be at least partially penetrated by the screed when applying the screed.

The drainage device may further comprise non-pictured water collecting means, which are in particular designed as a drainage channel. The drainage channel can be arranged above the drainage housing 1 after the application of the screed and the composite seal, so that wastewater which has entered the drainage channel can pass from an outlet opening of the drainage channel into the inlet opening 2 of the drainage housing 1. It is quite possible that the water collecting means are not formed as a groove, but for example, have a rotationally symmetrical shape.

The discharge device further comprises a plurality, in particular four supports 8. The supports 8 each comprise one, in the assembled state in particular vertical, rod 9 and a mounting foot 10 which can be attached to the subfloor, in particular by screwing. In Fig. 1 are corresponding dowels 11 and screws 12 shown.

The rod 9 protrudes through a receiving sleeve 13 of the mounting leg 10 so that the mounting foot 10 is displaceable on the rod 9 prior to assembly. The rod 9 has a lower foot plate 14, over which the mounting foot 10 can not be pushed down.

The drainage device further comprises a plurality, in particular four receptacles 16 for the rods 9. The receptacles 16 are formed sleeve-like, so that the rods 9 can project through them. The receptacles 16 are formed on which the drain housing 1 surrounding collar 6.

It is quite possible to arrange the receptacles 16 on other parts or sections of the drain housing 1.

The outside of one, in particular of each of the rods 9 has a cross-section deviating from a circular shape or a contour 17 which continues unchanged in the axial direction of the rods 9. In the in Fig. 1 to Fig. 6 illustrated first embodiment, the contour 17 of three at equal angular intervals of about 120 ° radially outwardly projecting projections 18 (see in particular Fig. 2 ).

Also, the inside of one, in particular of each of the receptacles 16 has a cross-section deviating from a circular shape or a contour 19, which continues unchanged in the axial direction of the rods 9. Fig. 2 shows that the contour 19 in the circumferential direction of the receptacle 16 adjacent portions 20, 21, which protrude alternately more or less radially inward.

In this way, located in the receptacle 16 rod 9 can be moved freely in a first rotational position of the rod 9 in the vertical direction through the receptacle 16. In contrast, in a twisted to the first rotational position second position, the rod 9 is fixed in the receptacle 16 by clamping. The contours 17, 19 thus act as a clamping means for the determination of the drain housing 1 at different heights relative to the support 8 or at different heights above the raw floor. The transition from the first to the second position can for example, by a rotation of the rod 9 in the circumferential direction by about 90 °.

It is quite possible to provide contours 17, 19 of the rods 9 and the receptacles 16, in which the transition from the first to the second position by rotation of the rod 9 in the circumferential direction by less or more than 90 °, for example by a Turn by 30 ° or 45 ° or 60 ° or any other suitable angle.

In this way, the height of the drain housing 1 above the unfinished floor can be specified in a simple manner prior to the introduction of the screed. The rods 9 are fastened with the aid of the fastening feet 10 and optionally with the aid of the decoupling units 15 on the unprocessed floor. Subsequently, the receptacles 16 of the drain housing 1 are applied to the rods 9. The drain body 1 can now be moved up and down in the vertical direction until it is at the correct height, in which, for example, the selected outlet pipe is at the same level with the drain line 5.

This height of the drain body 1 above the unfinished floor is fixed by rotation of the rods by for example 90 °. Possibly upward above the receptacles 16 protruding portions of the rods 9 are cut off.

The in the Fig. 1 to Fig. 6 illustrated drain device further comprises a plurality, preferably four plugs 22, which are each applicable to the tops of the rods 9 can be applied. For this purpose, the plug 22 has a cover plate 23 and three of the cover plate 23 downwardly projecting webs 24, each exactly in the Gaps between the projections 18 of the contour 17 of the respective rod 9 can protrude (see Fig. 2 ).
