Description

• – eine wasserundurchlässige Oberseite,
• – eine der wasserundurchlässigen Oberseite gegenüberliegende Unterseite,
• – eine in den Boden eingelassene Ablauföffnung,

wobei der Wasserablauf mindestens umfasst:

• – ein Ablaufoberteil zur Positionierung auf der wasserundurchlässigen Oberseite des Bodens,
• – ein Ablaufunterteil zur Montage unter der Unterseite des Bodens.

The present invention is a water outlet for installation in a groundwater laxative soil. This includes the ground

• - a water-impermeable top,
• - One of the water-impermeable top opposite bottom,
• A drain opening embedded in the floor,

wherein the water drain at least comprises:

• A drainage top for positioning on the water impermeable top of the floor,
• - A drain lower part for mounting under the bottom of the floor.

Such a water drain for installation in a surface water laxative soil is for example from the EP-A-0 333 168 known, which provides a shower floor element with a flat support component made of hard foam and a fixed on the hard foam mold plate covering. A disadvantage of this shower floor element is its dependence on a functioning seal of the intended Ablaufflanschteils to the shower floor element. In fact, this document represents the common idea for the near-bottom water flow in bathtubs and showers, after a soil is to be connected by means of a sealed flange with a sewer pipe. If there is a demolition or breakthrough within the seal, water damage is to be complained of in a disadvantageous way.

To solve this problem proposes the EP-B-1 712 169 a shower floor element with recessed drain opening within the rigid foam floor, in which a laid on the rigid foam floor water-impermeable film interact with parts of the drainage for sealing. Undisputedly, such a proposal is a possible solution for tearing seals. The disadvantage of this proposal is the fact that the implementation is almost exclusively possible for a prefabricated component, in the damage of the entire component is replaced - a subsequent maintenance or repair is not possible ,

Object of the present invention is against the background of the existing state of the art to provide the public with a water drainage for installation in a surface water leaching soil available, which is advantageous against a possible demolition or rupture within seals between the floor and sewer pipe and at the same time easy to maintain when necessary cleaning and repair work is.

However, the above list is not to be understood as limiting the invention to installation in these floors. The aforementioned soils have in common that on the one hand have an insignificant inclination, and on the other hand collected shower and / or rainwater as surface water and then passed to the discharge. Due to the insignificant inclination of the mentioned soils, the transition from the ground to the drainage via a sewage pipe is of great importance: in the hitherto customary use of seals between the floor and the drain, demolition or breakthrough within the seal inevitably lead to water damage.

According to the invention, such a seal between the floor and the sewer pipe is just dispensed with by 8th ) for discharging surface water between the water-impermeable top ( 2 ) of the bottom and the drain top ( 5 ) are provided. These funds ( 8th ) for the discharge of surface water can without any seal in a separate collection funnel below the bottom ( 4 ) of the soil. However, it is preferable if these funds ( 8th ) for discharging surface water into the drain body ( 6 ), to which end the means ( 8th ) for the discharge of surface water, water laxative with the drain lower part ( 6 ) are connected. This water laxative compound preferably comes without any seals.

At the same time, the matching counterpart is part of the drain ( 6 ) provided with an internal thread. Again, it is especially helpful here, if the water drain also means ( 11 ) for sealing, which between the drain lower part ( 6 ) and the underside ( 4 ) of the soil is positioned. These funds ( 11 ) may very particularly preferably be permanently elastic seals, for example, from a horizontally lying rubber ring with a vertical expansion component against which a pressure of the drain base ( 6 ) and underside ( 4 ) of the bottom when screwing the screw connections between the drainage top ( 5 ) and drain lower part ( 6 ) he follows.

According to the invention, the proposed water drain comprises means ( 8th ) for discharging surface water between the water-impermeable top ( 2 ) of the bottom and the drain top ( 5 ). These funds ( 8th ) for the removal of surface water are preferred as hollow channels in the drainage upper part ( 5 ) educated. In such a case, the surface water through the hollow channels in the drain top ( 5 ) either in a separate collection funnel below the bottom ( 4 ) of the soil or preferably in the drain ( 6 ), for which purpose the hollow channels in the discharge top part ( 5 ) Water laxative and preferably without any seals with the drain lower part ( 6 ) are connected.

• - the drain lower part ( 6 ) under tension to the underside ( 4 ) of the soil or the drainage base ( 6 ) under pressure of the most preferred permanently elastic seals ( 11 ) to the underside ( 4 ) pressed.

Within the scope of this very particularly preferred embodiment, the means ( 8th ) for the discharge of surface water not as hollow channels in the drain top ( 5 ), but as hollow channels in Einsetzrahmen ( 9 ) educated. In such a case, the surface water through the hollow channels in the Einsetzrahmen ( 9 ) either in a separate collection funnel below the bottom ( 4 ) of the soil or preferably in the drain ( 6 ), including the hollow channels in the Einsetzrahmen ( 9 ) Water laxative and preferably without any seals with the drain lower part ( 6 ) are connected.

The intended within the scope of this very particularly preferred embodiment variant Einsetzrahmen ( 9 ) is preferably designed for receiving a water drainage upwards concluding tread grid ( 10 ). In such a case, the insertion frame ( 9 ) usually a suitable upstand, in which then the step grid ( 10 ) can be used. The function of the step grid ( 10 ) is, on the one hand, the drain upper part ( 5 ) to protect against coarse and clogging dirt and from mechanical destruction. On the other hand, the step grid ( 10 ) to be able to just design the surface of the soil into which the proposed water drain is installed. For this purpose, the water-impermeable top ( 2 ) of the floor into which the proposed water drain is installed, with tiles ( 13 ) or other soil panels, which ideally form a surface, which with the top of the preferably built-in grille ( 10 ) runs evenly and does not allow any trip hazards.

The invention is based on the two 1 and 2 explained further, which represents a possible embodiment of the proposed water drain for installation in a surface water leaching floor. This soil is according to 1 in the case shown, a shower floor made of foamed plastic material, this is an XPS polystyrene foam plate, the front side a water-impermeable top ( 2 ) from a glued fleece ( 3 ), while on the underside ( 4 ) of this soil here no coatings to simplify the 1 are provided. Of course, especially glass mesh would have reinforced here Mortar coatings can be provided. In the XPS polystyrene foam plate is a drain opening ( 1 ) taken in. Above the circular discharge opening ( 1 ) is a square insert frame ( 9 ), as he also separately in 2 is pictured.

This 2 is better than that 1 that the insertion frame ( 9 ) has a centrally arranged, here circular opening, the bisector of which is congruent with the mid-perpendicular to the discharge opening ( 1 ) in the ground. The insertion frame ( 9 ) has on its underside a plurality of hollow channels as a means ( 8th ) for the discharge of water, said hollow channels from the lower-side outer edges of the Einsetzrahmens ( 9 ) in the direction and depending on the execution up to its centrally arranged circular opening - or before, but in any case within the drain opening ( 1 ) ending in the ground - run. On the top side, the insertion frame ( 9 ) first formed symmetrically to the perpendicular bisector through its opening, in 2 dashed shown depression into which the drain top ( 5 ) can be used. Furthermore, the insertion frame ( 9 ) an upstand for receiving a step grille ( 10 ) on.

Again 1 can be seen further, are next to the Einsetzrahmen ( 9 ) Tiles ( 13 ) provided on the fleece ( 3 ) as a water-impermeable top ( 2 ) of the shower floor are laid. Of the 1 can be seen that between Einsetzrahmen ( 9 ) and the tiles ( 13 ) is provided a preferably not filled with grout gap, through the surface water directly to the hollow channels at the bottom of the Einsetzrahmens ( 9 ) can flow. Of the 1 can be well taken that the tops of the tiles ( 13 ), the upstand of the Einsetzrahmens ( 9 ) and in the insertion frame ( 9 ) used tread grid ( 10 ) are evenly formed in a flight, so that no tripping hazards are given.

As already mentioned in the description of 2 executed, the insertion frame ( 9 ) a recess into which the drainage top ( 5 ) is used. The drainage top is in the illustrated case integral with a tube ( 7 ) with external thread as a component for connecting drainage top ( 5 ) and drain lower part ( 6 ) connected. At the same time, through the pipe ( 7 ) Water passing through the top of the drain ( 5 ) is to be discharged, the drain lower part ( 6 ).

Below the bottom ( 4 ) of the shower floor is the drain lower part ( 6 ), which on the one hand the matching counterpart to the screw connection with the pipe ( 7 ) with external thread as part of the drainage top ( 5 ), on the other via openings to the top, in the first the hollow channels at the bottom of the Einsetzrahmens ( 9 ) can drain. The main opening of the drain ( 6 ) is in the illustrated case on the pipe ( 7 ) with external thread with the drainage top ( 5 ) connected. The drain lower part ( 6 ) in the illustrated case very particularly preferred means for pivotal connection to a sewer pipe ( 12 ), these funds being in 1 are shown as four diagonal, mutually parallel lines, the drain lower part ( 6 ) in a with the drain top ( 5 ) here by means of the tube ( 7 ) with the external thread under tension to be joined upper part and a lower part to be pivoted to separate. Between bottom ( 4 ) of the shower base and the drain base ( 6 ) are also means for sealing ( 11 ) in the form of a plurality of rotationally symmetrical about the drain opening ( 1 ) provided in the shower floor extending rubber beads.
