Description

DRAINING ELEMENT FOR PARTICULARLY IN CONCRETE FLOORS

DESCRIPTION

The present invention relates to a drain element for arrangement, in particular in concrete floors, according to the preamble of claim 1.

Such drainage elements are used wherever water that is no longer required must be fed to a downpipe or the like for the purpose of disposal. Typical areas of application are, for example, the arrangement of such a drain element in the floor of shower rooms, changing rooms and passages in swimming pools or also in swimming pools, where such drain elements can also be used to drain large amounts of water from public swimming pools.

The first-mentioned purpose, i.e. the provision of such drainage elements in shower rooms, changing rooms and passageways in swimming pools, makes it clear that it may also be necessary to subsequently insert these drainage elements into an existing building structure, namely when a shower room and the like is to be retrofitted . Another purpose is, for example, to replace these drain elements, which can no longer be used, with a new drain element due to corrosion damage to existing drain elements. Both the new installation of such a drain element and the replacement of an already existing drain element make it necessary to intervene in the building structure around a floor opening to create the insertion of the drain element. In the case of concrete floors in particular, it is necessary for structural reasons that the installation opening for the drain element to be inserted is only made so large that the drain element can still be used, since large floor openings or if several are used Drain elements the required number of installation openings can endanger the existing building construction with regard to their statics.

In addition to this requirement that only small installation openings are permitted for structural reasons, it is necessary, particularly in the case of concrete floors, that the drain element ensures a good seal of the water to be discharged from the concrete floor, since otherwise the concrete floor would be damaged sooner or later.

Known drain elements of the generic type can, however, only take into account the last requirement of tightness in a more or less good way, this tightness being attempted to be made by integrating the drain housing of the generic drain element with that for installing the drain element in the floor structure to carry out the necessary arrangement frame so that there are no separating joints between the arrangement frame and the drain housing, which would be responsible for the undesired entry of water to be discharged into the concrete structure.

A generic drain element essentially has a drain grate, a frame that accommodates this drain grate, an odor trap in the form of a bell, an arrangement frame for arranging the entire drain element in the floor structure, and a drain housing made in one piece with this arrangement frame. Due to the one-piece design of this known drain element, however, it is necessary to insert a core hole in the concrete floor into which this drain element is to be inserted, which essentially corresponds to the entire diameter of the arrangement frame. In other words, this means that this large core hole already causes a not inconsiderable weakening of the concrete hole. dens occurs due to the resulting large notch effect, which can ultimately be inadmissible from a structural point of view even with a single core hole. Even more, the arrangement of several of these known drainage elements, for example in the case of a complete floor of a house to be retrofitted with shower rooms or the like, a swimming pool or a public sauna system would be inadmissible. These problems also arise in a similar manner when renovating existing drainage elements, since the floor structure has to be opened over a large area in order to remove the damaged drainage element and to reinsert a known large drainage element.

To overcome these disadvantages, the present invention is therefore based on the object of developing the drainage element of the generic type in such a way that, on the one hand, the requirements of structural engineering are taken into account and, on the other hand, a hermetic seal of the concrete floor against water to be discharged is ensured.

The invention created to achieve this object has the features specified in claim 1. Advantageous configurations thereof are specified in the further claims.

The present invention is based on the essential idea of deviating from the one-piece structure of the arrangement frame and drain housing, which has been carried out so far, so that the need to make large core bores is eliminated.

The drain element according to the invention has a drain grate, a drain grate receiving it, an odor trap, an arrangement frame and a drain housing, the drain housing being formed separately from the arrangement frame and being able to be connected to it. Through this separate design of the arrangement frame and the drain housing provided according to the invention, it is advantageously achieved that only such a core hole has to be inserted in the concrete floor, which essentially corresponds to the outer dimensions of the drain housing, since the complete arrangement frame of the Procedure- elements must be inserted. The arrangement frame is the device that is required to fix the drainage element in or on the concrete floor. In a particularly advantageous embodiment of the invention, it is provided that the drain housing is constructed in several parts. This drain housing can be formed by a tubular base body, an annular disk provided on one side on an inner end face of the base body and a tubular insert body penetrating the disk.

This multi-part design of the drain housing ensures that even difficult installation conditions in the concrete floor can be compensated for by, for example, a more or less strong axial displacement of the individual drain housing individual elements. In other words, this means that the drain housing can be assembled on site, which means that difficult installation conditions can be taken into account that cannot be met by a completely one-piece drain housing. According to an embodiment in accordance with the present invention, however, this drain housing can also be pre-assembled in one piece or can also be formed in one piece, this being sufficient in the case of "simple" installation conditions of the drain element in the concrete floor.

In continuation of the invention, a collar provided for arranging a drain pipe is arranged on the drain housing in such a way that the actual drain pipe can be inserted inside the tubular insert body, for example, until flush and secure contact occurs on this collar. Here, the drain pipe can also be glued into this, for example to form a material connection between the insert body and the drain pipe.

In a further development of the invention it is provided that the drain housing can be inserted into a receiving device on its side facing the drain pipe, by means of which the drain housing can be fixed to the concrete floor. In other words, this means that, for example in the case of a relatively thin concrete ceiling, a continuous core hole in the concrete ceiling is set in such a way that the drainage housing can be fixed via the receiving device on the underside of the concrete ceiling by means of a screw connection between the receiving device and the concrete ceiling. It is advantageous here if the receiving device is a fire-retardant device, for example a fiber silicate plate, with which the required fire protection can be achieved on the one hand and on the other hand a mechanical fixing of the drain housing on the concrete floor is achieved.

In a continuation of the invention, it is provided that the drain housing is arranged in the area of its outside of the housing at a distance from the surrounding floor area, that is to say the concrete floor, in which case the resulting gap space is then filled with a filler, in particular flowing mortar. In other words, this means that the space between the drain housing and the inside of the core bore placed in the bottom area is filled with a sealing medium, for example a flow mortar, into which, according to the invention, there is also an additional sealing compound Plastic base introduced, for example synthetic resin can be injected. This ensures that a sealing arrangement of the drain element in the core bore is ensured. To further increase the sealing effect, it is provided in accordance with the invention that the drain housing on its side opposite the drain pipe has a tube-like insert on the inside of the drain housing which can be sealingly connected to the arrangement frame. For this purpose, according to the invention, an insert can be inserted or glued into the base body of the drain housing, this insert protruding over the end of the base body in the direction of the drain grate of the drain element, viewed in the axial direction of the base body.

In a further development of the invention, the drain housing has on its side opposite the drain pipe an in particular disc-shaped or square base flange body provided with at least one bore, which overlaps the drain housing. In other words, it means that a disk-shaped or square flange body provided with a central opening is provided, which can be provided above the base body of the drain housing, this base flange body having an inner surface which largely corresponds to the inner surface of the base body of the drain housing in such a way that the base flange body advantageously extends up to the tube-like insert and can be hermetically sealed.

This configuration ensures that water to be discharged entering the drain housing via the drain grate only remains within the drain housing and cannot, for example, flow over the upper edge of the base body of the drain housing in order to be connected to the concrete floor .

According to a further embodiment of the invention, it is provided that the drain housing during its arrangement, that is to say during its assembly in the concrete floor, is overlapped on its side opposite the drain pipe by a particularly recyclable mounting plate, which is either fixed directly or indirectly to the concrete floor can be avoided so that the penetration of insulation material applied to the concrete floor into the drain housing is avoided. This ensures that, for example, screed placed on the concrete floor is prevented by the mounting plate from penetrating into the drain housing.

Finally, it is provided that the drain element on its side opposite the drain pipe is sealed to the outside against the insulation material applied to the concrete floor by a film arranged between the insulation material and a floor layer arranged thereon, for example a tile layer, which in the area its support on the base flange body is pressed hermetically sealing against the base flange body by a press flange which can be connected to the base flange body via a screw connection. In other words, this means that, for example, an annular moderate press flange is placed on the base flange body, which can be connected to the base flange body by means of a screw connection, the film in between being hermetically sealed against the base flange body in such a way that water can penetrate into the insulation material, for example the screed, safely is avoided.

To compensate for the height of the insulation material, it can also be provided that a pipe-shaped compensation element is provided between the base flange body and the drain grate frame, which largely corresponds in its axial longitudinal extent to the insulation material applied to the concrete floor.

The invention is explained in more detail below with reference to the drawing. This shows in

Fig. 1 shows schematically and partially in section a drain element used in a core bore in a first assembly stage and

Fig. 2 in a second assembly stage with an attached mounting plate and

Fig. 3 shows a completed drain element.

As can be seen from FIG. 1 of the drawing, the drain element 1 shown is inserted into a core hole 2 of a concrete ceiling 3. The drain element 1 has a drain housing 4, which in the embodiment shown has a tubular base body 5, an annular disk 6 arranged on the inside on the lower inner end face of the base body 5 and a tubular piece arranged on the inner surface of the disk 6 Insert body 7 is formed. The connection between the base body 5, the disk 6 and the insert body 7 is in each case made via a sealing adhesive connection, that is to say via a material connection, the base body 5, the disk 6 and the insert body 7 being made for this purpose a plastic, for example PVC. Approximately in the region of its half longitudinal extent, the insert body 7 has an annular collar 8 which is used to abut a drain pipe 9 which is inserted into the insert body 7 from below and which is advantageously also made of plastic, for example PVC, and into which Insert body 7 is glued.

In the exemplary embodiment shown, the drain housing 4 with its downwardly extending insert body 7 is accommodated in a receiving device 10, which in the exemplary embodiment shown is formed by two fire-retardant fiber silicate plates arranged one above the other, which are connected to one another via the screw connection 11 shown.

The arrangement of the drainage housing 4 on the concrete ceiling 3 takes place via the screw connection 12, also shown, in such a way that holes are drilled in the concrete ceiling 3, are inserted into the metal dowels, into the cylinder head screws, which are then provided with an external thread be screwed in. The drain housing 4 is arranged in the receiving device 10, for example, by means of a cohesive adhesive connection. In the exemplary embodiment shown, the drain pipe 9 is surrounded in the region of its arrangement on the receiving device 10 by a sleeve-shaped device 13, which can also be designed as a fire-retardant fire protection sleeve.

As can be seen from FIG. 1 of the drawing, a cover 14, for example made of PVC, is provided in the area of the end of the drain housing 4 opposite the drain pipe 9, which serves as protection against the ingress of dirt into the drain housing 4 during assembly.

Fig. 2 of the drawing shows a representation similar to that of Fig. 1, wherein the assembly of the drain element has progressed in this representation.

The gap space 15 that results between the outer circumference of the base body 5 and the inner circumference of the core bore 2 is filled with a filler, in the exemplary embodiment shown Flowing mortar filled, in addition to the flowing mortar synthetic resin is injected into the gap 15.

In the area of the top of the drain element 1, that is to say in the exemplary embodiment shown on the top of the drain housing 4, a tubular insert 16 is arranged on the inside of the base body 5 and extends in the axial longitudinal direction of the base body 5 over the upper end of the base body 5 extends. The insert 16 is hermetically sealed into the base body 5 via a material connection. A base flange body 18 is provided on the top 17 of the concrete ceiling 3, which is chamfered at an angle in the area of its outer circumference and extends over the drainage housing 4 radially inwardly directed over the core bore 2 to the insert 16 and at this point over a Material connection is sealingly connected to the insert 16.

A mounting plate 19 is arranged above the base flange body 18, which lies on the base flange body 18 and is guided over screw bolts 20 provided in the base flange body 18.

FIG. 3 shows the already finished drain element 1, without the mounting plate 19 shown in FIG. 2. At the top of the overall arrangement, a tile layer 21 is shown schematically, below which a film 22 is provided, which one between the tile layer 21 and the Concrete ceiling 3 introduced insulation material 23, for example screed, seals against the water to be discharged via the drain element. Arranged above the base flange body 18, which is pressed against the concrete ceiling 3 by the insulation material 23 via its lateral slope 24, is an annular press flange 25 which presses the film 22 in the region of the base flange body 18 against the base flange body 18, specifically by means of nuts provided bolt 20.

To compensate for the height h caused by the insulation material 23, a tubular-shaped compensation element 26 is arranged above the base flange body 18, side additionally supports a drain grate 27 which serves to accommodate a drain grate 28.

As can be seen from FIG. 3, on the side of the drain element 1 opposite the drain grate 28, a kinking pipe piece 29 is arranged in a schematic manner, via which waste water leaving the drain pipe 9 can be fed to a downpipe (not shown). A bell 30 arranged inside the drain housing 4 serves as an odor trap and has a bracket on its top for easy handling of the bell 30.

With regard to the features of the invention not explained in detail above, reference is expressly made to the claims and the drawing.
