Abstract

The system has a long border profile (4) with an anchoring limb (7), which is roughly flat. A narrower long section of the limb projects over the lateral edge of a balcony or patio, and has a mounting strip profile (8) for detachable or permanent fastening of one or more further profiled components (5). The strip may be located on the underside of the anchoring limb, which faces towards the ground when it is correctly installed. The strip may also bend downwards at the outer edge of the anchoring limb, which faces towards the balcony. The outside upper edge (9) of the projecting section may be inclined.

Description

The invention relates to a drainage system for balconies, which consist of a support plate and screed applied thereon. The drainage system comprises at least one elongated end profile, which has an essentially flat anchoring leg that can be placed on the supporting plate of the balcony before the screed is applied, on the outside of the balcony of which there is a profile section that protects the supporting plate and the screed from external weather influences. This profile section is composed of a profile leg which has approximately the height of the screed and essentially protrudes upward at right angles and a profile leg which points obliquely downwards and at least partially covers the support plate.

Such an end profile is known from German utility model 90 04 119. This end profile is used to keep driving rain or liquid flowing off the front edge of the balcony away from the front wall of the balcony, so that no moisture can penetrate into the screed or the support plate from there.

In multi-storey residential and commercial buildings, several balconies of the same size are usually aligned vertically one above the other, which leads to the problem that dirty water dripping from the end profile of a balcony hits the balcony below and can contaminate it. This gives rise repeatedly to disputes, particularly in the case of residential buildings with condominiums, in which contractual impairments of property by neighbors are generally excluded. In principle, this problem can be avoided by installing gutters - also known from the utility model mentioned - but this solution is often dispensed with for aesthetic reasons, as can easily be determined on a city tour. Such conventional gutters are perceived as unattractive on a balcony due to their size and shape. In addition, the gutters known from the above-mentioned utility model must already be taken into account when planning the house, since they are anchored in the screed, just like the end profile. However, the dirt problem often only emerges clearly over the years.

Based on this, the invention has for its object to provide a drainage system for balconies, which allows a drainage of dirty water such that an underlying balcony - or even a ground floor terrace - is not affected by dirty water discharged from the balcony above, without doing so on conventional gutters to have to fall back.

This object is achieved in that in a drainage system of the type mentioned in the a wastewater drainage channel is provided at an angle downwards.

The cross section of the dirty water drainage channel can be essentially U-shaped or also arch-like.

In an advantageous development of the invention, the dirty water drainage channel projects beyond at least one of the two ends of the elongated end profile. This ensures that in the dirty water channel of a balcony, waste water running to this end is drained away without further measures in a direction away from the balconies or a terrace below this balcony.

The dirty water drainage channel can have an opening facing away from the balcony, on which a dirty water spout is provided. The term wastewater spout is understood to mean a short water baffle or pipe. The opening can be provided at any point in the longitudinal direction of the profile, so that it is possible to discharge the dirty water from the dirty water drainage channel at a desired, advantageous point.

In an advantageous development of the invention, the waste water drainage channel is an integral part of the end profile. This allows a cost-effective production of the end profile and waste water drainage channel in a single operation, e.g. in the extrusion process.

In another advantageous development, the dirty water drainage channel is a separately manufactured component that can be attached to the end profile. Such a design of the end profile allows attachment of the Dirty water drainage channel even after completion of the balcony.

A particularly advantageous way of attaching the waste water drainage channel to the end profile is possible if the obliquely downward profile leg of the end profile has an elongated groove-like depression with a narrowed mouth, into which the dirty water drainage channel can then be inserted or hooked. Such a configuration of the end profile and the waste water drainage channel makes it easy to install the waste water drainage channel without additional tools or fastening means such as e.g. Screws or rivets possible.

End profiles are known in which a profile strip which is bent downward into a position approximately parallel to the side wall of the balcony is connected at the edge of the profile leg facing away from the anchoring leg. In an advantageous development of the invention, an elongated groove-like depression with a narrowed mouth, which extends in the longitudinal direction of the profile and into which the dirty water drainage channel can be inserted or hooked in, is then provided on this profile strip. The end face of the profile strip facing away from the sloping downward profile leg can be beveled towards the balcony, so that a drip edge for the dirty water forms on the side of the end face facing away from the balcony. This has the advantage that, even when the dirty water drainage channel is not hooked in or pushed in, dirty water running off the drip profile is always carried away from the balcony.

The said narrowed mouths can be formed by two rib-like strip sections formed on the end profile at a parallel distance from the associated flat side. This has the advantage that the recess simple and inexpensive - in the case of a metallic end profile, for example in the extrusion process - can be produced, so that such a depression does not have to be subsequently milled into the profile, for example. The advantageous type of manufacture will be discussed in the description of the figures. In addition, a stiffening effect is achieved with these rib-like strip sections, which stiffens the end profile both during installation and during transport and makes it less susceptible to twisting. This means that such end profiles are bent less frequently during transport and are therefore rendered unusable.

The stiffening and reinforcing effect not only has a positive effect during transport, it is also much easier to install on site with a stiffer profile than with a flexible one.

The dirty water drainage channel can advantageously be designed such that a fastening section running in the longitudinal direction of the channel is provided, which can be inserted or hooked into the groove-like recess of the end profile and which has a cross section which is at least partially complementary to the cross section of the groove-like recess. The fastening section can have a strip section covering the side of the narrowed mouth facing away from the groove-like recess, a strip section penetrating the mouth and a strip section attached to the recess-side end of the strip section penetrating the mouth, approximately parallel to the strip section which forms an inner surface of the recess and forms the end profile.

In the waste water drainage channel designed in this way, it is possible in an advantageous further development that the height of the strip section folded over parallel to the inner surface of the depression opposite the mouth is maximally the same to measure the width of the mouth of the groove-like recess, so that the dirty water drainage channel can be hung anywhere in the end profile. In this case, the attachment can be facilitated in that the flank of the strip section pointing from the drainage channel to the flat section of the end profile which is parallel to the flat surface of the recess forming an inner surface of the recess is beveled at least over part of its height towards the strip section passing through the mouth.

To discharge the dirty water from the dirty water drainage channel, a dirty water spout can be arranged at at least one end of the channel. This spout drains the dirty water in any direction. Alternatively or in addition, it is also possible to connect the waste water drainage channel to a downpipe in a manner known per se, e.g. B. by pushing a downpipe connection sliding sleeve on one end of a dirty water drain channel.

In some applications of an inventive system, it can be advantageous to close the waste water drainage channel at at least one end. For this purpose, a separately produced end cap can be slid onto one end of the sewage channel, which closes the channel at this end in a watertight manner at the side and downwards.

In an advantageous further development, the drainage system has at least one further elongated end profile (feed profile) for the lateral balcony edges, which has an essentially flat anchoring leg, on the balcony edge of which a waste water feed channel opening into or above the waste water drainage channel is arranged. With such a feed profile, this can be done over the side edges of a balcony outflowing waste water is collected and fed to the waste water drainage channel provided on the front.

Depending on the type and design of the overall system and the balconies to be drained therewith, it may be expedient to connect the dirty water supply duct and the dirty water discharge duct via corner connecting elements. Such corner connecting elements can be made of metal or plastic, whereby by using suitable plastics with a certain elasticity, length changes of the generally metallic waste water drainage channels or supply channels due to thermal expansion can advantageously be compensated for.

In an advantageous development, the feed profile has a profile leg that at least partially covers the screed. This profile leg protects the support plate from external weather influences.

In order to provide a larger contact area and thus the liability of e.g. In order to improve the anchoring leg of the feed profile to be anchored on the screed by means of tile adhesive, the underside of the anchoring leg facing the screed can be provided, at least in sections, with surface-enlarging recesses.

In such cases, in which no exact values about the amount of dirty water are available when setting up the balcony and laying the drainage system, an advantageously developed drainage system is expediently used, in which an essentially vertically downward-pointing profile leg of the end profile points downward Profile strip is provided, which has an elongated recess with a narrowed mouth, on which an elongated substantially strip-shaped guide screen by means of a narrowed to the Mouth at least partially complementary fastening section can be fastened to the end profile. A waste water drainage channel can then be fastened to such a guide screen. If the contamination of an arial located under the balcony does not turn out to be critical, then instead of a dirty water drainage channel, only the elongated strip-shaped dirty water guide screen is attached. However, if the contamination proves to be critical, a waste water drainage channel can be attached to the guide panel at any time.

In an advantageous development of the invention, this dirty water drain channel is clamped to the guide screen by means of at least one screw-nut connection, an opening for the screw being provided in the guide screen and in the dirty water drain channel, one of the openings being essentially circular Cross-section has, while the other is designed as an elongated hole in such a way that the waste water drainage channel can be attached to the guide screen in a manner that is variable in height and / or inclination.

Fig. 1 shows a plan view of a balcony 2 laid with tiles 1, which emerges from a house wall 3. The house wall 3 has an opening for a door to the balcony 2. The end face of the balcony 2 facing away from the house wall 3 was provided with an end profile 4, a dirty water drainage channel 5 being provided on the end profile 4. On the side of the balcony 2 extending at right angles from the house wall 3 there was a feed profile 6 provided, the dirty water supply channel opens into the dirty water discharge channel 5. The dirty water drainage channel 5 opens out over the two ends of the elongated end profile 4. Accumulated dirty water can now flow off in the dirty water drainage channel 5 without a balcony located under this balcony being soiled. The dirty water accumulating on the side walls of the balcony 2 running at right angles to the front of the house is fed from the feed profiles 6 to the dirty water drainage channel, which in this exemplary embodiment is an integral part of the end profile 4 shown in section in FIG. 2. While in this exemplary embodiment the dirty water supply channels open into the dirty water drain channel 5 in the manner described, it is alternatively also possible to connect the channels by means of suitable corner connecting elements, which are inserted, for example, into the channels to be connected to one another or plugged onto or pushed onto these channels can then be compensated for by using suitable materials known per se for the production of the corner connecting elements and any changes in length of the channels due to thermal expansion.

In Fig. 2, an elongated end profile 4 is shown in cross section, which has a substantially flat anchoring leg 7 that can be placed on the supporting plate of the balcony before the application of screed, on the outside edge of which there is a supporting plate and the in the later intended installation position Screed is protected from external weather influences profile section, which is composed of a profile leg 8 projecting essentially at right angles upwards and a profile leg 9 pointing obliquely downwards. A dirty water drainage channel 5 is provided on the profile leg 9 pointing obliquely downward. In this embodiment, the waste water drainage channel 5 is an integral part of the end profile 4 and essentially U-shaped. It consists of a profile strip 10 which is bent downward on the edge of the profile leg 9 which is inclined downwards and angled downward towards the anchoring leg, a profile strip 10 which is folded down approximately parallel to the end wall, a profile strip 11 which is bent at right angles to the side facing away from the balcony and forms the bottom of the waste water drain channel 5 and one from the bottom of the channel Profile strips folded upwards at right angles 12.

At the upper edge of the upwardly projecting profile leg 8, a bent profile strip 13 is applied, which extends backwards over the anchoring leg 7 and whose width is less than the width of the anchoring leg. This backward-facing profile strip prevents liquid from penetrating into the area of the screed close to the end wall. In addition, the profile strip 13 stiffens the profile 4 in its upper area against unwanted deformations.

On the free edge of the profile strip 13 lying above the anchoring leg 7 there is additionally a narrow strip section 14 directed downward to the anchoring leg 7, which anchors the end profile in addition to being anchored by the anchoring leg in the screed and also causes further stiffening to stabilize the end profile.

In the exemplary embodiment in FIG. 2, the anchoring leg 7 has a multiplicity of — in the illustrated case — square or rectangular openings 15. The screed penetrating through the openings 15 and adhering within the openings 15 to the top of the support plate anchors the end profile 4 after it has hardened in a positive and / or non-positive manner on the support plate. It should be emphasized that the openings can also be provided in a shape other than the square or rectangular shape shown, in particular triangular or otherwise polygonal, round or rounded shape. Such a profile can be produced simply and inexpensively from a suitable aluminum alloy using the extrusion process. In principle, however, comparable profiles can also be produced in a different way and from other metallic materials or plastics. As an example, only the possibility of producing partial profiles in the stamping and pressing process from sheet metal, for example corrosion-resistant steel sheet, is to be mentioned, which then or the like by connecting certain profile legs by welding, riveting or the like. be connected to a profile corresponding to the profile 4 shown.

3 shows a slightly modified end profile 4, in which the outer flank of the strip section 16 facing away from the profile leg 8 is chamfered. As a result, when the flowable screed is later applied, favorable conditions for the screed to flow around this strip section 10 are created without, however, impairing the stiffening effect of the strip section 16 on the entire profile 4. Furthermore, in this embodiment of the end profile 4, two elongated groove-like recesses 17, 18 are provided, into which connecting elements according to the German patent application P 44 43 634.3 can be inserted for connecting two profiles. The elongated groove-like recess 17 is provided on the flat side of the profile leg 8 facing the screed in the intended installation position, while the groove-like recess 18 is provided on the side of the profile section protecting the support plate from external weather influences in the intended installation position of the support plate.

FIGS. 4a, b and c show a further exemplary embodiment of an end profile 24 according to the invention and a dirty water drainage channel 25. In this embodiment is the dirty water drainage channel 25 a separately manufactured and attachable to the end profile 24 component. The end profile 24 consists of the anchoring leg 27, on the outside edge of the balcony, the essentially right-angled profile leg 28 and the obliquely downward profile leg 29 are attached.

On the edge of the profile leg 29 facing away from the anchoring leg, a profile strip 30 adjoins downward in a position parallel to the balcony side wall. To connect the waste water drainage channel 25 to the end profile 24, the profile strip 30 has an elongated, groove-like depression 31, which extends in the longitudinal direction of the profile and has a narrowed mouth, which is formed on the end profile 24 by two, at the same distance parallel to the side of the profile strip 30 facing the balcony rib-like strip sections 32, 33 is formed. The cross section of the elongated groove-like depression 31 lying between the flat side of the profile strip 30 facing the balcony and the narrowed mouth has the shape of a rectangle.

The dirty water drainage channel 25 has a fastening section running in the longitudinal direction of the channel, which consists of a strip section 34 covering the side of the narrowed mouth facing away from the groove-like depression, a strip section 35 penetrating the mouth and a strip section 35 penetrating the recess side of the strip section penetrating the mouth , in the intended installation position approximately parallel to the strip section 36 which then runs parallel to the support plate 30. 4c, the end profile 24 is shown, the dirty water outlet channel 25 having its fastening section being inserted from the side into the groove-like depression provided on the end profile 24.

FIGS. 5a and 5b show slightly modified exemplary embodiments of an end profile 24 and a waste water drainage channel 25 according to FIGS. 4a and 4b. The modified end profile 24 has on the edge facing away from the anchoring leg 27 of the profile leg 28 which later covers the screed and extends at a right angle upwards into a profile strip 37 folded into a position parallel to the anchoring leg 27.

In these exemplary embodiments, the dirty water drainage channel 25 has a fastening section in which the height of the strip section 38 folded parallel to the inner surface of the depression 31 opposite the mouth corresponds to the width of the mouth of the groove-like depression 31 of the end profile 24 and that of the strip section 35 downwards has turned over. This configuration ensures that the waste water drainage channel 25 can not only be inserted into the groove-like recess 31 from one end of the end profile 24, but can also be hooked into the narrowed mouth at any point and can then be locked in the recess by lowering it. The hooking is facilitated in that the flank of the strip section 38 pointing away from the drainage channel is beveled over part of its height towards the strip section 35 penetrating the mouth in the manner shown in FIG. 5. In this exemplary embodiment of an end profile according to the invention, the end face of the profile strip 30 which later faces the dirty water drainage channel is chamfered in such a way that a drip edge for the dirty water forms on the side of the end face remote from the balcony. This has the advantage that even when the dirty water drainage channel is not hooked in or pushed in, dirty water running off at the end profile is conducted away from the balcony.

FIG. 6 shows a dirty water spout 41, which is provided for attachment to an opening in the dirty water drainage channel facing away from the balcony. Such a dirty water spout is advantageously provided on the abutting edge of two dirty water drainage channels to be connected in alignment with one another. The dirty water spout consists of a water baffle 42, which is attached approximately in the middle of a fastening profile and has walls 43, 44 that are folded over at the side.

The fastening profile consists of five profile strips 46, 47, 48, 49, 50, each folded at right angles to one another, which form an essentially U-shaped profile which is open at the top and which has a cross section which is at least partially complementary to the cross section of an assigned waste water drainage channel. Such a dirty water spout 41 can now advantageously be provided on the abutting edge of two dirty water drain channels to be connected to one another simply by snapping onto the joint of the separate dirty water drain channels. With integral production of the waste water drainage channel with the actual end profile, the fastening profile can also be inserted into the inside of the waste water drainage channel. The front walls of the waste water drainage channels facing away from the balcony must be cut out in the area of the joint so that any waste water can be discharged via the spout 41.

FIG. 7 shows a dirty water spout 51 provided for wringing at one end of a dirty water drainage channel. This consists of a water baffle 52 attached to one end of a fastening profile with sheet metal strips 53, 54 bent upwards at the side, which form lateral boundary walls for the watercourse. The fastening profile is constructed in the same way as the fastening profile of the dirty water spout shown in FIG. 6. Such a dirty water spout 51 can be Mount advantageously at one end of a waste water drainage channel according to the invention by simply pushing it in or sliding it onto the channel, which then drains dirty water in a desired direction.

FIG. 8 shows a section through one side of the balcony according to FIG. 1, on which a feed profile 6 according to the invention is provided. The feed profile 6 has an essentially flat anchoring leg 61, on the outside edge of which there is a profile section 62 which is bent upwards at right angles, on the side of which facing away from the balcony there is a dirty water supply channel 63.

In this exemplary embodiment, the dirty water supply channel 63 is formed by the profile section 62 bent upwards at right angles, the extension of the anchoring leg 61 to the outside of the balcony and a profile leg 64 running parallel to the profile section 62 and attached to the balcony-outer edge of the extension of the anchoring leg 61. The dirty water supply channel 63 thus has a U-shaped profile. The profile leg 64 is attached to the extension of the anchoring leg 61 in such a way that it not only runs partly upwards at right angles and thus forms an outer wall of the dirty water supply channel 63, but also runs downwards at right angles and thus the screed 65 completely, and that Support plate 66 of the balcony is at least partially covered and thus protects it from external weather influences.

The anchoring leg 61 is placed on the screed 65. To seal the screed 65, a sealing film 67 is laid on the screed and the anchoring leg 61 in the example shown. A tile adhesive 68 was then applied to this sealing film 67 and the tiles 1 were laid. In the transition area between the extension forming the bottom of the dirty water supply channel 63 of the anchoring leg 61 and the outer profile leg 64, a chamfered chamfer 69 is expediently formed. The water discharged via the feed channel 63 then flows at a distance from the outer profile leg, so that in the transition region to the dirty water discharge channel 5 or 25 of the front end profile 4 or 24 it does not cross the edge of the section of the profile leg attached to the anchoring profile 61 64 flows. That is, the dirty water discharge channel of the end profile 4 or 24 does not have to protrude beyond the supply profile 6 to the outside.

In such cases, in which the contamination of an area of a building provided under a balcony is not critical, for example because the balcony only extends over the area of the garden close to the house, it may be sensible to merely place a waste water drainage channel 25 on the front end profile 24 attach an elongated strip-shaped dirty water guide screen 70 as illustrated in FIG. 9. This guide screen 70 is designed with respect to the means holding it in the elongated groove-like recess of the end profile 24 in accordance with the dirty water discharge channel 25 according to FIG. 5b, so that it can be easily retrofitted to the lower profile strip 30. The height of the panel 70 should be such that its lower free edge extends below the lower edge of the balcony support plate. This then ensures that, even in the event of strong winds, the dirty water running off through the end profile 24 drips off at the lower edge of the panel 70 and is not guided to the end face of the balcony and soaks the support plate or the screed there.

In addition, it is advisable to provide the visible front of the panel 70 with a decorative surface coating, which therefore also improves the appearance of one provided with such panels in the region of the balconies Building. If the contamination then turns out to be critical, for example because the area provided under the balcony is suddenly to be used, a waste water drainage channel 25, as shown in FIG. 10, can be attached to the guide panel 70. This is expediently clamped to the guide panel 70 by means of a screw-nut connection, not shown here. For this purpose, in the leg of the dirty water drainage channel 25 facing the balcony, which in the exemplary embodiment shown here has a U-shaped cross section and consists of three elongated profile legs, and in the guide panel 70 the openings 82, 84 indicated by the dotted lines are provided, whereby the opening 84 in the waste water drainage channel 25 has a circular cross section, while the opening 82 in the guide screen 70 is designed as an elongated hole.

The lowest point of the opening 84 in the waste water drain channel 25 is above the upper edge of the profile leg which forms a waste water drain channel outer wall, facing away from the balcony, so that even without a special sealing of the opening 84 it is ensured that dirty water is always present even with a large amount of dirty water is led away from the balcony. If a screw is inserted through these openings and the dirty water drainage channel 25 and the guide screen 70 are clamped by tightening a nut attached to the end of this screw, the inclination of the dirty water drainage channel can be changed as desired by forming the one opening 82 as an elongated hole. It should be emphasized at this point that the elongated hole can of course also be provided in the dirty water drainage channel and that both openings 82, 84 can also be formed as elongated holes, which are then advantageously arranged at an angle with respect to their longitudinal extent.

FIG. 11 shows a dirty water supply profile 6 according to the invention, in which the anchoring leg 61 has recesses 80 which increase the surface area in sections on its underside facing the screed. These recesses enlarge the surface of the anchoring leg facing the screed and cause it to be secured by means of an adhesive, e.g. 8, anchoring leg to be fixed on the screed due to the now larger contact area. In this exemplary embodiment of a dirty water supply profile 6 according to the invention, the bottom 81 of the dirty water supply channel is inclined obliquely downwards transversely to the longitudinal extent of the supply profile 6 towards the balcony. This inclination of the floor 81 instead of the fillet in the embodiment shown in Fig. 8 has the advantage that the outflowing dirty water in any case led to the side of the dirty water supply profile closer to the concrete support plate and then at its end on its balcony-facing side into the dirty water -Drain channel is directed.

FIG. 12 shows a modified exemplary embodiment of an end profile 24 and a dirty water drainage channel according to FIG. 4c. The modified dirty water drainage channel 25 has in its channel inside an elongated groove-like depression 86 with a narrowed mouth that runs in the longitudinal direction of the channel. The depression 86 is provided on the side of the profile leg forming the outer wall of the U-shaped dirty water drain channel 25 facing away from the balcony and is formed by two rib-like strip sections 87, 88 formed on the dirty water drain channel 25 at an equal distance parallel to this side of the profile leg . A connecting bolt, not shown here, can be inserted into the recess 86 as already described in connection with FIG. 3. If several dirty water drainage channels 25 are to be connected in alignment, which is the case with one very large balcony may be the case, such a connecting bolt can be used to make a flush connection in a particularly simple and advantageous manner in the waste water drainage channels designed in this way. The formation of the groove-like depression 86 also has the advantage that a sealing strip, for example a metal sealing tape, to be glued over the abutting edge of two dirty water drainage channels 25 can be inserted at one end into the groove-like depression and is thus protected against the weather.

Figure 13 shows a further embodiment of a separately manufactured and on a corresponding end profile, e.g. the end profile 24 according to FIG. 4c, attachable waste water drainage channel 95, in which the water-carrying channel part is designed in the form of a circular arc. To fasten this waste water drainage channel 95 to an end profile, a fastening section is provided at the end of the channel part which is circular in cross-section, facing the balcony and which, in the manner described above (see, for example, FIG. 5b), penetrates the narrowed mouth of a groove-like depression provided on a corresponding end profile Strip section 35 and a strip section 38 engaging in the groove-like recess. Through the provision of attachable waste water drainage channels with different cross-sectional shapes, e.g. The waste water drainage channel 95 shown in this figure or the dirty water drainage channel 25 according to FIG. 12, it is possible to change the overall visual impression even after the completion of a building or to choose dirty water drainage channels when retrofitting such profiles as part of renovation work, that fit particularly harmoniously into the building / street scene.
