Description

7501 7

The present invention relates to a drainage system according to the preamble of claim 1.

The drainage of the wet rooms (bathroom, toilet, sauna, etc.) 5 includes a collector drain in the pipe lift shaft, to which the connection sewers from the furniture are connected. Usually in the premises are used floor or so-called. a wall well to which e.g. tub, sink or washing machine outlet pipes. In wet rooms, a sewer-10 well has been used, which is located in connection with the collector sewer in the pipe riser. If a floor drain is used, the required height and connection to the collector guest must be taken into account in the subfloor structure. Alternatively, the floor structure of the wet room must be raised unreasonably.

15 For these reasons, the use of a conventional floor drain is difficult.

The object of the present invention is to eliminate the inconveniences described above and to provide a completely new type and more practical sewer system.

The invention is based on the idea of constructing a kind of combined wall and floor drain system in which the advantages of both systems can be exploited. In this case, the water trap part is still placed in the pipe riser, but a dry well part is connected to it, which acts as a floor well.

More specifically, the sewer system according to the invention is mainly characterized by what is set out in the characterizing part of claim 1.

By means of the invention, e.g. the following benefits:

Several 30 (3) dry well connections can be placed in the same water trap section, which makes it possible to drain different rooms, preferably in the same water trap section,

Among other things, the outlet pipes of the sink, bathtub and washing machine can be placed in either the dry well or water trap-35 part. In this case, the pipe pulls can be made short 2 75017, depending on the furniture layout. At the same time, the entire furniture placement is made completely free. The drain pipe leading from the dry well to the water trap section is oval in shape to achieve the preferred strength and flow properties. In the pipe joints, the expansion joint is taken into account with double rubber ring joints, so the pipes can be placed in the floor structure of the wet room. The non-woven insulation of the floor is associated with drywall with a mattoren-10 gas joint, which prevents the risks of peeling the glue. Wall well systems have previously been connected with adhesive joints, in which case sufficient durability has not been achieved. The system meets the flow requirements of the building regulations set-15 mat.

The placement of the equipment in the pipe lift room is made easier due to the piping options available in the system. This even reduces space usage. The system can be factory-installed in a wet room-20 element completely ready for use.

In the following, the invention will be examined in more detail by means of an example according to the appended drawing.

In the exemplary case, the water trap section 1-3 is located in the pipe riser 25 and is connected to a (non-drained) sewer via a water trap structure U. The water trap section is equipped with an upper deck 2.

At the lowest point of the wet floor 13, a dry well type floor well 10-12 is made, comprising a lower-cylindrical part 10 and an upper, larger-diameter cylindrical part 11 above it. At the top there is still a cover part 12. The total depth of the floor well 10-12 is low compared to conventional floor drains. From the floor well 10-12 the pipe 5-9 running in the floor 13 leads to the water trap-35 part 1, the pipe 5 ~ 9j comprising in the example case the actual pipe part Ts pipe connections 5 and 9 and the connection 3 75017 pieces 6 and 8 are flattened, e.g. oval, to improve flow and strength properties.

The number of dry well-type floor wells to be connected to one water trap part may be one or three or even higher instead of two according to the example case 5.

Within the scope of the invention, it is conceivable that only pipes 5-9 from the floor wells 10-12 are connected to the water trap part 1-3 to be adapted to the pipe-rising space. It is also conceivable that the water trap section 1-3 also simultaneously functions as an actual wall well, in which case it has at least one wall well-type drain opening.

Tubes 5-9 may, of course, also be conventional circular cross-section tubes.

Finally, it should be noted that, within the scope of the invention, it is not necessary for the water trap part 1-3 to be explicitly arranged in the riser, but it can of course also be placed on the floor if necessary.

Claims (2)

4,75017 A drainage system (1 to 12), especially for use in wet rooms, preferably comprising a water-lock part (1 to 3) to be placed in the pipe riser, - an actual water lock (4) by means of which the water-lock part (1 to 3) TO is connected to the drain, and - a floor well (10-12) of the dry well type, which is connected to the water trap part 15 (1 to 3) via a pipe (5-9) or the like running in the floor (13), characterized in that the floor well (10 - 12) is a so-called . a shallow structure with a diameter substantially greater than its depth and that the tube (5 to 9) has only a slight inclination with respect to the horizontal. A system according to claim 1, characterized in that the cross section of the tube (5-9) is substantially oval or flat.
