Abstract

Sealing device (1) for sealing a drainage arrangement, including a flexible sealing film (3) with an opening (4), through which waste water can pass, and a connecting portion that is connected with the sealing foil (3) and that can be connected with a portion of the drainage arrangement.

Claims

1. A method for at least partial installation in a floor or a room of a drainage arrangement, comprising the steps of:

providing a drainage body (2) with an opening (9), through which water is drainable, the drainage body (2) having on its top side a groove (8),

providing a flexible sealing film (3),

connecting a connecting portion with the sealing film (3) and with a portion of the drainage arrangement, wherein the connecting portion comprises a seal (6) and a support (5) which supports the seal (6), the connecting portion and the flexible sealing film (3) have an opening (4) defined therethrough through which waste water is passable, wherein the connecting portion and sealing film (3) comprise a sealing device (1) arranged at least partially above the drainage body (2), so that water that has passed through the opening (4) of the sealing film (3) is receivable in the opening (9) of the drainage body (2),

connecting the seal (6) to the support (5) before attaching the sealing device (1) to the drainage arrangement,

inserting at least in portions the support (5) together with the seal (6) arranged circumferentially about the opening (9) in the drainage body (2) into the groove (8), and

snapping in place in the groove (8) or clipping into the groove (8) the support (5) together with the seal (6),

wherein the groove (8) on the top side of the drainage body (2) is a circumferential groove formed by an inner wall closest to the opening (9) in the drainage body (2), an outer wall farthest from the opening (9) in the drainage body (2) and a bottom wall connecting the inner and the outer walls;

wherein the support (5) together with the seal (6) arranged circumferentially about the opening (9) in the drainage body (2) is inserted into the groove (8), the seal (6) does not physically contact the outer wall of the groove (8); and

wherein the insertion step further comprises the step of maintaining the position of the seal (6) relative to the support (5) before and after insertion of the support (5) together with the seal (6) into the groove (8).

2. The method according to claim 1, wherein the groove (8) surrounds the opening (9) of the drainage body (2).

3. The method according to claim 2, wherein the groove (8) is at least partially spaced apart from the opening (9) of the drainage body (2) such that a gap (10) exists between the opening (9) of the drainage body (2) and the groove (8).

4. The method according to claim 3, wherein the gap (10) encircles the opening (9) of the drainage body (2).

5. The method according to claim 3, further comprising the step of arranging an odor trap (11) and a removable frame (12) for the odor trap (11) in the gap (10) between the groove (8) and the opening (9).
