Description

INSTALLATION ELEMENT TO BE ARRANGED IN FLOOR LAYERS WITH ONE

FLOWABLE HOUSING

DESCRIPTION

The present invention relates to a built-in element for arrangement in soil layers with a flow-through housing, each with at least one inlet and outlet passage according to the preamble of claim 1.

Installation elements of this type are always arranged in floor layers, for example concrete floors, when it is necessary to introduce media which can flow into the floor, for example water, or to discharge media of this type from the floor into the atmosphere, such as gases.

A typical application of introducing water into the ground is when, after rainwater has been applied to the roof area of a building, this rainwater has to be collected via a rain gutter and then fed to the ground via a downpipe or, for example, to a sewage line laid in the ground.

This makes it clear that a large part of the area of use of such drainage elements is where these installation elements are firmly installed in the floor and are therefore arranged under, for example, concrete layers or asphalt layers. Since the rainwater downpipes to be connected to the built-in elements must then also be laid at least in the area of their end section in the concrete floor, the pipe end piece must be replaced after a possibly occurring one Defect, such as rusting, is extremely labor-intensive and therefore costly, since the solid concrete floor must be pried open and grouted again after the defective pipe section has been replaced.

Since the intended use of such built-in elements is also extremely versatile and accordingly pipes with a wide variety of cross-sectional dimensions have to be connected to these built-in elements, a built-in element which can be connected to the pipe piece must be provided for every possible cross-sectional shape, so that even in the event of a later replacement of the defective pipe section can only be used again and again with a pipe section having the same dimensions. It is in the nature of things that, in addition to the already mentioned high labor costs when replacing a defective pipe section, this also leads to high costs with regard to the production and storage of generic installation elements, since the many possible cross-sectional dimensions correspond to those with the Installation elements to be joined to pipe pieces many different installation elements must be manufactured and stored.

A generic installation element is designed for arrangement in floor layers, such as a concrete floor, and generally has a flow-through housing, each with at least one inlet and outlet passage, which is designed for the arrangement of flow-through connection devices. Such a generic installation element is poured, for example, into the concrete floor, in which case, for example, a rainwater downpipe is arranged at the inlet opening of the housing of the installation element in such a way that water enters the flow-through housing via the inlet passage and in turn leaves it via the outlet passage also provided on the housing . As already mentioned, however, this generic installation element has the disadvantage that it is designed for direct connection to a device through which flow can flow, so that a large number of such generic installation elements is required for different applications. To eliminate the disadvantages described, the present invention is therefore based on the object of developing the built-in element in such a way that a single built-in element can accommodate a multitude of possible applications and that the replacement of a connecting device to be connected to the built-in element is facilitated.

The invention created to achieve this object has the features specified in claim 1. Advantageous refinements of this are described in the further claims.

The installation element created according to the invention for arrangement in floor layers has a flow-through housing, each with at least one inlet and outlet passage, which is designed for the arrangement of flow-through connection devices, wherein in the area of at least one of the passages, a flange body can be attached to the housing, which passes the passage to the outside seals against the bottom layer and has a tubular extension for arranging the connection devices.

The present invention is based on the essential idea of no longer connecting the connecting devices to be connected to the installation element directly to the housing of the installation element, but rather to arrange on the installation element a flange body to be connected to the housing of the installation element, which on the one hand the passage of the installation element hermetically closes tightly to the outside and, on the other hand, a connection to the connection devices permits such that connection devices of various types can be connected to the installation element.

The installation element created according to the invention has the advantage that to connect such flowable connection devices to the installation element, it is only necessary to connect these connection devices to the tubular piece provided on the flange body without, for example, the otherwise necessary introduction of the flowable connection devices into the housing of the component is required. In other words, this means that, in the case of a built-in element arranged in the floor layer, for example a concrete floor, the connecting device is connected to the tubular extension of the flange body, so that the floor is no longer necessary if the connecting device needs to be replaced ¬ layer to open to the depth of the installation element so that the connecting device connected to the housing of the installation element can be separated from the latter.

It is also of great advantage that the installation element according to the invention eliminates the need to provide a plurality of such installation elements having different connection dimensions, since the tubular extension of the flange body can have a standardized dimension, so that the connection device through which the flow can flow is connected to the only a correspondingly designed intermediate piece is required, which can, for example, compensate for different diameter dimensions of the connecting device and the tubular attachment. This is advantageous because it enables the later replacement of the flow-through connection device by, for example, such a connection device with diameter dimensions that reject the connection device previously used. For this purpose, it is then only necessary to open the floor area on the floor surface up to the area of the intermediate piece, while the, for example, deeply concreted-in installation element can remain intact in the floor.

The built-in element can have a multi-part housing in the form of a base plate, for example a circular-cylindrical housing body and a connecting plate for arranging the flange body, one of the flowable connecting devices being able to be arranged on the housing body. In other words, this means that the direction of flow through this installation element is determined by the flange body, since it has a passage and by the housing body, since it has a further connection through which flow can pass, so that the direction of flow through

SPARE BLADE (RULE 26) is defined, for example, from the flange body into the housing body and from this.

In continuation of the invention, the housing body, the connection plate and the base plate are hermetically sealed to form the housing, in particular glued or welded in such a way that an integral sandwich bond is formed and that to seal the passage to the outside against the base layer between the connection plate and the flange body an adhesive connecting the connection plate and the flange body is provided.

In this way it is advantageously achieved that the hermetically sealed sandwich composite of housing body, connecting plate and base plate prevents the flowing medium entering the installation element from undesirably escaping into the floor layers surrounding the installation element. Such an undesirable leakage of water, for example, would lead to a lasting destruction of this floor layer when it enters the floor layer surrounding the installation element, for example concrete.

For this purpose, it is also provided that a film is arranged between the connection plate and the flange body, which extends in the area towards the passage into the area of the material connection between the flange body and the connection plate and is directed outwards through the housing of the Installation elements extend into the floor layer.

This ensures that an undesired entry of, for example, water into the floor layer surrounding the installation element, for example concrete, is reliably avoided at that point on the film which has a defect, that is to say in the region of due to the introduction of the installation element in the bottom layer inevitable opening of the sealing film. The fact that this film extends into the area of the material connection between the connection plate and the flange body, that is to say into the area of the hermetically sealed sandwich bond between the connection plate and the flange body, means that the film in these Sandwich composite is integrated so that water does not pass through this film into the floor area.

According to the invention, in order to achieve a further reinforcement of the indispensable seal against the floor area, a screw connection is to be provided for arranging the flange body on the connection plate such that the flange body with adhesive introduced between the flange body and the connection plate to form an Cohesive press composite is pressed against the connection plate.

In other words, this means that the screwing of the integral connection already produced by the adhesive between the connection plate and the flange body produces an increased sealing effect by creating a press connection, which is achieved in that the flange body and the Connection plate with adhesive arranged therebetween are pressed against each other so that the gap which is unavoidable between the flange body and the connection plate is securely closed, according to the invention the foil being brought up to the area of the material connection between the connection plate and the flange body, so that a hermetically sealed sandwich press composite results.

In a continuation of the invention, it is provided that the tubular extension has a cross-sectional shape corresponding to the cross-sectional shape of the housing body. This ensures that a receptacle volume of the built-in element, which is dependent on the cross-sectional shape of the housing body, is not undesirably reduced by the tubular extension. Such a reduction would mean, for example in the case of a rainwater downpipe, that due to the narrowing of the cross section in the area of the tubular extension, a backwater could form in the rainwater downpipe, which could lead to this rainwater downpipe overflowing.

In a continuation of the invention, it is provided that the tubular extension is integrally or positively or also integrally formed with the flange body can. In other words, this means that the tubular extension can already be formed on the flange body during the manufacture of the flange body, but also an initially separate production of the tubular extension and the flange body and a subsequent positive or material connection is possible.

In a continuation of the invention, it is finally provided that the tubular extension can be connected in a form-fitting or material-locking manner to a flow-through connecting device. The tightness of the overall arrangement required in the area of the installation element is ensured by the possible integral connection, for example by an adhesive introduced between the tubular extension and the flowable connecting device.

Finally, it is provided according to the invention that the

Installation element on the connection plate has a mounting plate having at least one hole in such a way that the installation element introduced into the bottom layer can be subjected to a pressure test. For this purpose, the built-in element, which is placed in the concrete, for example, is subjected to a pressure test for leaks under pressure with water. For this purpose, the installation element, including its inlet and outlet passages, is first filled air-free with the water then used for pressing. For this purpose, a mounting plate having at least one hole can be attached to the connecting plate, that is to say a mounting plate which has a continuous ventilation hole, which is initially opened when filling and closed by a tight threaded plug when pressed off.

The installation element according to the invention can be used, for example, as a floor drain and / or for draining rainwater and / or for venting drain systems and / or also as a pipe cleaning closure.

The invention is explained in more detail below with reference to the drawing. This shows in Figure 1 shows schematically a built-in element in a view from the side.

2 schematically shows a built-in element installed in a concrete layer with a ventilation pipe attached and

Fig. 3 shows a built-in element similar to Fig. 2 with attached drain element.

As can be seen from FIG. 1 of the drawing, the built-in element 1 in the embodiment shown has a housing, generally designated by 2, which is constructed in several parts and has a base plate 3, a connecting plate 4 and a housing body 5.

The base plate 3, the connection plate 4 and the housing body 5 can have any shape, but are preferably circular disk-shaped with respect to the base plate 3, circular with respect to the connection plate 4 and circular-cylindrical with respect to the housing body 5. As can be easily seen, a branch pipe 6 is arranged in the region of the outer circumference of the housing body 5, which branch tube 6 is inserted into the housing body 5, for example if the housing body 5 is formed from a plastic, for example PVC or HDPE, to form a hermetically sealed closure of the housing 2 can be glued or welded in, but an integral design of the housing body 5 with the branch tube 6 is also possible.

In general, the design of the housing 2 of the built-in element 1 is such that, in the case of a multi-part construction of the housing 2, the base plate 3, the connection plate 4 and the housing body 5 are designed to form a hermetically sealed arrangement in a sandwich arrangement. In other words, this means that the circular-cylindrical housing body 5 is inserted with its underside or top side in grooves running in each case in the bottom plate 3 and the connecting plate 4 and there with the bottom plate 3 or the connection plate 4 is integrally connected by, for example, gluing or welding.

After inserting the built-in element into the bottom layer, it is possible due to the requirements for the tightness of the built-in element to arrange a mounting plate (not shown) on the connecting plate 4, which has a vent hole such that the air contained in the built-in element through this vent hole when filling water can escape into the installation element, after which this ventilation hole can then be closed by a hermetically sealed threaded plug, so that the tightness of the installation element can be ensured by pressing with water.

As can be seen from the drawing, an annular flange body 7 is arranged on the upper side of the connecting plate 4 and can be attached to the connecting plate 4 via a screw connection 8.

In the area of the inner surface of the casing ring, the flange body 7 has a tubular extension 9 which extends from the flange body 7 in the direction away from the housing 2 of the installation element 1. Between the support surface of the flange body 7 on the upper side of the connection plate 4, a dash-dotted adhesive is introduced which, in the case of the flange body 7 and the connection plate 4 being formed from a plastic, for example PVC or HDPE, for a material bond between the see Flange body 7 and the connecting plate 4 provides.

At the same time, in the region of the radially outer extension of the flange body 7 or the connecting plate 4, a film 10 is arranged which extends outward from the housing 2 of the installation element 1 and which in the region of the tubular extension 9 or the housing body 5 is a passage for a flowable fluid Has formed passage opening, but on the outside in the area of the radially outer surface of the flange body 7 is between the flange body 7 and the connection plate 4 and extends as far as the material connection formed by the adhesive between the flange body 7 and the connection plate 4, so that they are tightened the screw connection becomes an integral part of the press assembly formed from the flange body 7, the connecting plate 4 and the adhesive, so that the tightness of the overall arrangement against the floor layer surrounding the installation element 1, for example concrete or additionally applied insulation material such as screed, is ensured.

2 of the drawing schematically shows an application example of the installation element, with a flange body 11 arranged on the tubular extension 9, the tubular extension 12 of which, for example, is integrally arranged above the tubular extension 9 of the flange body 7 and on the installation element 1 opposite side has a further flange body arranged on the flange body 11, which also has a tubular extension and extends in the direction away from the installation element 1.

The last-mentioned tubular piece is in turn connected to a ventilation pipe 13, so that in the exemplary embodiment shown the built-in element 1 can be used, for example, for ventilation or a ventilation of a space (not shown) arranged in the floor layer. For the sake of clarity, it should be mentioned that the ventilation pipe 13 extends into the atmosphere and is surrounded on its side facing the installation element 1 by, for example, a humus layer, which is then followed by a schematically represented drainage layer, with another floor then in the direction of the deeper floor layer ¬ layer follows, followed by an insulation layer, for example a screed layer 14, above which the already mentioned film 10 is arranged. Below these floor layers, the installation element 1 is cast in a further floor layer, for example a concrete floor, so that it can be seen that in the event of the ventilation tube 13 being replaced or exchanged, the ventilation flange 13, the further flange body, does not prevent the Flange body 11, the flange body 7 and the installation element 1 formed overall arrangement must be separated, but if, for example, a ventilation pipe of larger diameter is used, the floor area only has to be as deep as the flange body 7 or tubular extension 9 which extends in the direction opposite to the floor surface is to be opened, since at this point, for example, a further intermediate piece can then be inserted without having to open the floor layer in which the installation element is located, for example the concrete floor.

FIG. 3 of the drawing shows a further application example of the installation element 1, the structure of the individual floor layers corresponding to that according to FIG. 2 and therefore not being explained in more detail.

Instead of the ventilation pipe 13 shown in FIG. 2 of the drawing, the arrangement according to FIG. 3 has a drain element 15, which can be used, for example, very generally for drainage, the one occurring in the floor area surrounding the drain element 15 Water can enter the drain element 15 through slots and can then be drained off via the installation element 1 and the branch pipe 6. It should be noted here that the application examples shown serve only for clarification and it is also possible, for example, to arrange a structure corresponding to FIG. 3 in the roof area of a flat roof of a building, so that the drainage element 15 is arranged in the roof area Green area can lie, while the installation element 1 then comes to rest in the area of the solid roof structure formed by, for example, concrete.

This makes it clear that the built-in element is a multifunctional device that can be used for a wide variety of purposes.

For example, it is possible to use the built-in element as a floor drain, for example in a basement floor. All that is required for this is to arrange an intermediate ring, a grate frame and a grate on the installation element, an odor trap being able to be inserted into the drain pipe 6 for this purpose. However, it is also possible to use the built-in element as a floor drain in more hygienically demanding areas of application, for example in kitchens or in hydrotherapeutic departments, for which purpose a vapor barrier can be introduced into or into the tubular extension 9. This results in an arrangement similar to that according to FIG. 2 with the difference that in the region of the flange body 11 a further sealing film shown in FIG. 2 can be introduced via thermal insulation and a screed, followed by a further tubular piece Approach with a grate frame and grate running on the top.

Finally, it is also possible to provide the built-in element in an arrangement similar to that according to FIG. 2 as a basic line ventilation element in such a way that not a space lying below the surface of the earth is ventilated or ventilated, but rather a pipe system arranged in the bottom layer, that is to say for example, a sewage pipe system. It is also possible to arrange the installation element several times in the pipeline system in such a way that it is used as a pipe cleaning closure without water being drained off. In this case, a tightly screw-on plate is arranged on the upper side of the drain element.

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