Description

The invention relates to a floor drain for the sanitary area, especially for showers.

From the document EP 2 423 395 A1 For example, a shower floor sealing system of a sanitary room is known, comprising a waterproof flexible layer, such as a sealing membrane, having an insert for watertight connection to an outlet opening in the shower tray. In a first embodiment of this sealing system, a siphon is provided which has an inlet opening with an annular flange. In this flange from the top of the tightly connected with the sealing membrane tubular insert is used, which is achieved by a ring seal tightness between the insert and the flange. It should be noted that the upper edge of the flange of the inlet opening is lower than the S-shaped body of the siphon and thus when installing the siphon in the bottom of the flange can never reach to the bottom surface. In a second embodiment of the sealing system, an outlet tube is poured vertically into the bottom and then the insert part is inserted into the outlet tube. In a further embodiment of the sealing system, a siphon is shown in sections with an upwardly projecting inlet pipe into which an insert part is inserted. Also in this embodiment, the upper edge of the inlet nozzle does not protrude up to the bottom surface, but ends in the bottom layer. The height compensation between the water-tight flexible layer resting on the ground surface and the siphon must be accomplished by the insert part.

A disadvantage of this known sealing system is the fact that the inlet opening of the siphon in the installed state does not protrude to the bottom surface, but in a soil layer, such as a screed layer is embedded. There is therefore an undefined distance between an upper edge of an inlet opening of the siphon and the ground surface. If this distance is compensated by more or less deep insertion of the insert, the craftsman can not be sure that the insert is inserted at least so far that it extends down beyond the O-ring seal mounted in the inlet opening. He has therefore not guaranteed to have made a tight connection. On the other hand, if the craftsman has to insert the plug too deeply into the inlet opening of the siphon so that the waterproof flexible layer does not lift off the ground surface, it may happen that the liquid passage of the siphon is partially or wholly displaced by the plug in Fig. 6 to see, which reduces the flow rate. It is in EP 2 423 395 A1 Although described that the siphon is provided with two flanges from which, depending on the total depth of the upper flange can be removed. However, this proposal does not solve the problem of undefined installation depth, since the removal of the flange must be done before pouring the siphon into the soil layer and the figures show that the siphon is sunk deep into the ground.

It is the object of the present invention to provide a floor drain and a method for installing the floor drain in a floor, in which the above-mentioned disadvantages of the prior art are avoided. In particular, a defined distance between the inlet of the floor drain and a plug-in part of the waterproof flexible layer should be ensured and reliably prevented that either no tight connection is made during installation by manual errors or the fluid passage of the floor drain is laid.

In a floor drain according to the invention for the sanitary area, in particular for showers, for installation in a floor with a bottom layer height and a bottom surface, comprising a drain body with a connection to a drain pipe and communicating with the terminal, in installation position of the drain body upwardly extending inlet pipe and a watertight flexible layer applied to the bottom surface with a sealing collar insertable into the inlet tube of the drain body, the drain body measured from its underside to an upper edge of the inlet tube has a drain body height greater than the bottom layer height measured from a base surface the bottom, optionally minus a mounting distance of the drain body to the base surface, wherein the inlet tube consists of a material which can be cut by means of a saw or a knife.

In the case of a floor drain according to the invention, the inlet tube of the drain body can advantageously be cut to length flexibly in its installation height. Thus, the drain body height can be adapted to the particular structural conditions of the installation situation particularly easily. Furthermore, level matching with a soil layer or a screed layer is simply possible with the novel floor drain. Thus, during installation it is ensured that a standard screed covering is ensured and that a sealing collar always rests as a seal on a floor surface of a floor layer or on the screed layer of the floor.

Suitably, in a floor drain according to the invention at least one with the drain body, preferably height adjustable, connectable mounting member is provided which defines the mounting distance. Advantageously, with the one or more mounting elements, both the drain body and a drain pipe connected thereto can be adjusted in their respective installation positions. By height-adjustable connectable mounting elements it is possible to set a defined slope of the drain pipe and set a mounting distance between a base surface of the floor, such as a raw concrete ceiling, and a bottom of the drain body or set this. Depending on the soil layer height of a soil layer or screed layer to be produced, different installation distances can be set. For example, the floor drain can be fixed without mounting distance, in which case the bottom of the drain body rests against the base surface of the floor.

Particularly advantageous is the mounting element on a guide element of the drain body height adjustable displaced and can be fixed. In this embodiment, the mounting elements are mounted height adjustable on the drain body by means of one or more guide elements. For this purpose, the guide element has, for example, a guideway with a length or a height, along the guideway, a mounting element can be fixed in height adjustable in its position, for example with a fixing screw. Thus, the mounting distance can be determined with a mounting element particularly easy and align the drain body in its installed position.

In a preferred embodiment of the invention, a bottom drain comprises a top insertable into the sealing collar essay, wherein the attachment preferably has a tubular insert for insertion into the sealing sleeve, which insert is particularly preferably made of a material cut by saw or knife material, and one with the Insert part rigidly or rotatably connected frame attachment comprises. Suitably, the attachment is adjustable to a height of a floor covering, for example of floor tiles. Furthermore, a frame attachment can accommodate a cover. The frame attachment is preferably rotatable and can thus be adapted to a tile image.

In a further advantageous embodiment of the invention, in a floor drain, the sealing collar on an inwardly projecting sleeve heel. In this embodiment, the cuff paragraph a maximum insertion of the Sealing collar in the inlet tube of the drainage body guarantee and the cuff paragraph, serves as a support for an odor trap.

Particularly expediently, a floor drain according to the invention has an odor trap which can be introduced through the attachment into the sealing collar, wherein the odor trap rests on the collar shoulder of the sealing collar in the inserted state. Advantageously, the distance of the odor trap to the bottom surface is constant regardless of the length of the inlet tube, whereby the odor trap the floor drain is easily removable if necessary.

Advantageously, a floor drain according to the invention on a Bauschutzdeckel having on its first side a shape which is adapted to an inner wall of the inlet tube, and on its opposite second side has a shape which is adapted to an inner wall of the sealing sleeve. Thus, a single protective cap may be used to cover both the inlet tube and the sealing collar.

A method for installing a floor drain according to the invention in a floor of a sanitary area, in particular in a floor of a shower, comprises the following steps:

• Mounting a drain body on a base surface of the bottom, optionally forming an assembly distance between the drain body and the base surface, wherein the drain body is provided with a connection to a drain pipe and an inlet communicating with the inlet pipe, wherein the drain body is aligned and mounted so that the inlet tube extends upwards;
• Connecting the connection of the drain body with a drain pipe;
• Erecting a bottom comprising at least one bottom layer on the base surface, in particular the spraying and / or pouring of filler material, such as cement-bound plastic particles or screed material, onto the base surface, the inlet pipe projecting above the bottom surface after the floor has been erected;
• Cutting off a portion of the inlet pipe projecting above the ground surface;
• Applying a sealing sleeve provided with a waterproof flexible layer on the bottom surface, wherein the sealing collar is inserted from above into the inlet tube of the drain body, and
• Inserting an attachment from above into the sealing collar, wherein the attachment is inserted so far into the sealing collar, that an upper edge of the attachment has a predefined distance to the bottom surface.

In the case of the installation method according to the invention, the length of the inlet pipe can be particularly advantageously adapted to a bottom layer height and a predefined distance of an insert part of the article to the thickness of a floor covering.

In an advantageous variant, the alignment and mounting of the drain body on the base surface by means of at least one connectable to the drain body, preferably height adjustable mounting element takes place in a mounting method according to the invention. With the help of one or more mounting elements, both the drain body and a drain pipe connectable thereto can be set up particularly comfortably in their installation positions.

Conveniently, in an installation method according to the invention, the inlet pipe is closed with a removable protective cover before the floor is erected. In this process variant is reliably avoided that during installation unwanted impurities can get into the interior of the floor drain and this would otherwise be laboriously removed.

In a further advantageous variant, in a mounting method according to the invention, a sealing compound is applied between the bottom surface and the flexible layer and / or on an upper side of the flexible layer and the bottom surface when the waterproof flexible layer provided with a sealing collar is applied to the bottom surface. Due to the waterproof flexible layer, the sealing collar advantageously offers a large surface, which can be reliably sealed off with a sealing compound towards the bottom surface.

Appropriately, in a mounting method according to the invention, the sealing sleeve is sealed before applying the sealing compound with a removable protective cover, being used as Bauschutzdeckel preferably a bilaterally usable Bauschutzdeckel whose other side is designed to close the inlet tube. In this embodiment variant, in an installation method, both the sealing collar and the inlet tube can advantageously be closed by means of a protective cover which can be used on both sides. Thus, resources are saved and in the course of installation one and the same protection cover can be used first to cover the inlet pipe and later to cover the sealing collar.

Advantageously, in an installation method, the attachment has a tubular insertion part for insertion into the sealing collar, and the insertion part is inserted in the before Cut sealing sleeve to a desired length, preferably with the insert a frame attachment is rigidly or rotatably connected. In this variant of the method, the insert part can be adapted to a covering height of a floor covering, for example floor tiles. By a frame attachment, which is preferably rotatably mounted on the attachment, a cover, which remains visible later in installation position for a user of the floor drain, particularly comfortable to a laying pattern of the flooring, for example, to a joint pattern of floor tiles, can be adjusted.

In a further development of the invention, a floor covering is applied to the floor surface in an installation method after inserting the article, wherein preferably before the application of the floor covering the article is covered with a Bauschutzrahmen. The Bauschutzrahmen serves to prevent damage to the floor drain or the ingress of contaminants during the laying of the floor covering.

Appropriately, in an installation method according to the invention an odor trap in the essay or the sealing sleeve or the drain body is used. Such an odor trap comprises, for example, a closure bottom and a floating body mounted therein. In the case of an installation method according to the invention, the odor trap can advantageously be used last in the already completed floor drain.

Fig. 1 shows the components of a floor drain 1. A template 10 is placed during installation of the floor drain 1 on a base surface 101, for example, a raw concrete floor cover 101 of a floor 100. The template 10 has corresponding template recesses 11, by means of which, in a manner known per se, markings for adjusting mounting elements 20 on the raw concrete ceiling 101 can be drawn, for example, with a pencil or a marking pen.

The mounting members 20 are here substantially formed as a metal angle, wherein on a longer leg, a fixing screw 21 and a shorter leg, a ground screw 22 are provided for screwing into the bottom 100. The longer leg has a height 23 or leg length 23 of the mounting element 20. The ground screw 22 is inserted in a screw hole 24, for example in a screw long hole, of the mounting member 20. As will be explained in the following, a mounting height or a mounting distance between the drain body 30 and the level of the base surface 101 of the floor 100 can be determined with the mounting elements 20, which are fixed in height adjustable manner on a drain body 30.

The drain body 30 has a connection 31 for a drain pipe. The nozzle-shaped connection 31 protrudes laterally from the drain body 30 at a lower portion in the installed position and is communicatively connected to an inlet pipe 32 at the upper portion of the drain body 30. Web-shaped or slot-shaped guide elements 33, which have a length 34 or height 34, are arranged on the outside of the drain body 30 and serve to receive in each case a longer leg of a mounting element 20. By means of the fixing screws 21, the mounting elements 20 can be fixed in position in the guide elements 33. For this purpose, the mounting elements 20 can be adjusted in height along the length 34 of each guide element 33 in their position or installation height above the base surface 101 of the floor 100. A drain body height 35 of the drain body 30 is measured from a bottom 36 to a top edge 37 of the inlet pipe 32. The inlet tube 32 is made of a manually cut with a saw or a knife material and therefore can especially on site be cut easily and comfortably. In the installed position, the inlet tube 32 protrudes with its diameter 38 in the longitudinal axis direction 39 substantially vertically upwards. In order to prevent the ingress of impurities in the floor drain 1 during the installation work, a protective cover 40 is further provided, which is advantageously used multiple times. A first side 41 of the protective cover 40 is adapted to the diameter 38 of the inlet tube 32, a second side 42 of the protective cover 40 is adapted to a sealing collar 60, which is attached in the further course of installation of the floor drain 1. For this purpose, the sealing collar 60 has a flat, waterproof flexible layer 50 with an upper side 51 and a lower side 52, which is connected watertight to the sealing collar 60. By cutting the inlet tube 32 to length, the waterproof flexible layer 50 is positioned in its vertical position in such a way that it rests flush on a surface of a still to be produced layer, for example a screed layer, of the subfloor 100.

Alternatively, the waterproof flexible layer 50 can be sealed with a sealing compound between the still applied screed layer of the subfloor 100 and its underside 52. Alternatively or in addition thereto, the waterproof flexible layer 50 can also be sealed with a sealing compound on its upper side 51, which optionally lies between the upper side 51 and a further, overlying layer of a floor covering.

The sealing collar 60 has an inwardly protruding collar shoulder 65, whereby a maximum insertion depth of the sealing collar 60 is defined in the inlet tube 32 and also serves as a support for a later to be used odor trap 70. The odor trap 70 here comprises a closure bottom 71 and a floating body 72 movably mounted relative thereto and functions like a conventional siphon closure. Furthermore, an attachment 80 is provided, which comprises a substantially cylindrical or tubular insertion part 81 and an adjoining thereto frame attachment 82, which forms an upper edge 83 of the attachment 80. The attachment 80 is inserted with its insert 81 from above into the sealing collar 60. The insert part 81 is here also made of a manually cut with a knife or saw material and can be adapted locally to the height conditions of a floor covering, such as floor tiles. Advantageously, the frame attachment 82 can be rotated relative to the floor drain 1 in order to adapt the contour of the frame attachment 82 shapely, for example, to the joint pattern of floor tiles. The upper edge 83 of the frame attachment 82 is adjusted so that it is flush with a surface of the floor covering. One up for the user of the Floor drain 1 visible cover 85 is inserted flush in the frame attachment 82 or inserted. The cover 85 can be easily removed for cleaning purposes or for inserting the odor trap 70.

In order to protect the floor drain 1 during the final work in the sanitary area, for example during joint work or during the installation of floor tiles, from contamination, a building protection frame 90 is provided, which is inserted instead of the cover 85 in the frame attachment 82 or covers this.

The pictures Fig. 2 to Fig. 4 respectively show the progress of the preparatory work required for the installation of the floor drain 1 in a corner of the room formed by the base surface 101 of the floor 100, for example the raw concrete ceiling 101, and the adjacent building walls 130. As in Fig. 2 is shown at the beginning by means of a template 10, an installation position of a drain body 1 marked. For this purpose, the layers of the template recesses 11 are traced onto the raw concrete corner 101 with a marking pen, for example with a pencil.

In Fig. 3 is symbolically indicated that at the corresponding markers now the required holes are set with a drill in order to fix the ground screws 22 of the mounting elements 20 in the wells optionally using fastening plugs.

In Fig. 4 the drain body 30 are arranged with the adjustably mounted in the guide elements 33 mounting members 20 at the installation. The inlet tube 32 is closed with a protective cover 40. Fig. 5 shows in an exploded view obliquely from the side of the drain body 30 and the plurality of mounting elements 20 prior to their assembly.

The pictures FIG. 6 to FIG. 16 show as a continuation of Fig. 4 the sequence of further work for the installation of the floor drain 1 in the corner of the room.

In Fig. 6 the drain body 30 is attached to the mounting elements 20 which are adjustably mounted in the guide elements 33, already screwed screwed at the installation in the bottom holes. The protective cover 40 has already been removed here for the now following leveling work.

In Fig. 7 is illustrated how now by multiple, preferably crosswise, applying a spirit level 190 at the top edge 37 of the inlet tube 32 of the drain body 30 is leveled in a longitudinal direction in the vertical direction 39 substantially vertical mounting position. For this purpose, the adjustable in the guide elements 33 in the longitudinal direction 34 and in its altitude 34 mounting elements 20 can be adjusted accordingly by operating the fixing screws 21 and fixed in the installed position relative to the drain body 30 again. In this case, in addition to the vertical orientation of the inlet tube 32, a corresponding inclination angle 155 of the drainage pipe 150 for a sufficient gradient of the wastewater must also be taken into account in the adjustment, as shown in FIG Fig. 8 is illustrated. The floor drain 1 is now positioned so that an assembly distance 25 or a mounting height 25, between the base surface 101 of the bottom 1, so the Rohbetonbodendecke 101, and the bottom 36 of the drain body 36, and a drain body height 35 to the upper edge 37 of the inlet pipe 32 are realized. Optionally, the drain body 30 with its bottom 36 without mounting distance 25 rest directly on the raw concrete floor cover 101. The vertical height of the drain body 30 is thus in the installed position 200 in any case the drain body height 35, which is optionally extended by the mounting distance 25.

Fig. 9 shows the floor drain 1, after on the raw concrete floor cover 101, a further bottom layer 102, for example, a screed layer 102, having a bottom layer height 105 and a bottom surface 110 has been applied. The floor surface 110 is shown here with a slope, wherein the floor drain 1 is located at the lowest point of the floor surface 110. The free end of the inlet pipe 32 is closed again with the protective cover 40 during the screed work.

In Fig. 10 FIG. 4 illustrates how the end portion of the inlet tube 32 projecting above the bottom surface 110 is cut off and discarded with a saw 195.

In Fig. 11 It is shown how the sealing collar 60 is inserted into the inlet tube 32. The waterproof flexible layer 50 attached to the sealing collar 60 is then sealed with a sealant applied between its underside 52 and the bottom surface 110, as shown in FIG Fig. 12 already shown in installation position 200. The sealing collar 60 is in turn closed by the protective cover 40.

Fig. 13 shows the installation, now in addition to the top 51 of the flexible layer 50, a sealant has been applied and the bottom surface 110 is now prepared for tiling or laying a final floor covering.

In Fig. 14 It is shown how the attachment 80 is adapted to the floor height of the flooring still to be laid. For this purpose, the protective cover 40 is removed and the insert 81 of the attachment 80 is inserted into the sealing collar 60. The insert part 81 is then optionally cut to length in its length with a saw 195, so that the insert 81 and the attachment 80 is seated on the sealing sleeve shoulder 65 and the upper edge 83 of the attachment 80 at the same level as the flooring to be laid. In the frame attachment 82 is still a Bauschutzrahmen 90 here.

Fig. 15 shows the floor drain 1 before the final tiling. The frame attachment 82 with the building protection frame 90 inserted therein protrude above the level of the floor surface 110 in accordance with the height of the floor tiles.

In Fig. 16 It is shown how the odor trap 70 is inserted into the floor drain 1. The adjacent floor covering 120 is already completed and the floor tiles are grouted.

Fig. 17 shows the fully installed and connected floor drain 1, wherein the odor trap 70 is already installed and the floor drain 1 is ready for use with the cover 85 is closed.

Fig. 18 illustrates a sealing collar 60 with a waterproof, flexible layer 50. In the side view here, the inwardly tapering sleeve heel 65 is clearly visible.
