EP2995732B1 - Façade gutter - Google Patents

Description

The invention relates to a facade gutter for the drainage of, in particular, granular soil areas, e.g. B. terraces, facade areas or flat roofs according to the preamble of claim 1.

For the drainage of terraces, facade areas or flat roofs, drainage channels known as "facade channels" are common, which are installed as drainage in a floor to be drained. Surface water continues to flow from above into the cover channels of the facade channels. Such a facade channel is for example from the DE 10 2007 010 073 A1 known. This known gutter is designed quite complex for various reasons. On the one hand, a large number of individual parts must be kept in stock and assembled during installation; on the other hand, transport and storage are complex due to the high space requirements, even though the channels themselves have only a very small volume of material. This drives up the cost of such channels.

EP1001101A2 relates to a channel for the drainage of surface water and / or bulk material. The has a lower part, which is opposite a displaceable upper part. In the area of a shoulder of the pull-out upper part, a closed area is formed which can be pushed in or pushed out. The upper part of the sewer and the lower part of the sewer have seepage openings, in particular slots that have an identical and possibly overlapping structure when pushed together.

EP1522637A2 refers to a gutter for removing surface water and leachate with two side walls, a bottom and a water-permeable cover. One of the side walls is perpendicular to the cover. The second side wall has two sections. The lower section is flush with the floor and the upper section is perpendicular to the floor and lid and parallel to the first side wall.
The invention has for its object to develop a facade gutter of the type mentioned in such a way that a simple and inexpensive assembly as well as simple and inexpensive storage at low manufacturing costs are possible with little effort. When assembling different channels, a facade channel should also be designed such that a simple and effective alignment of these channels to each other is made possible.

This object is achieved by a facade gutter according to claim 1. In particular, this task is performed by a facade gutter for the drainage of, in particular, granular soil areas, e.g. B. terraces, facade areas or flat roofs, comprising a formed as a sheet metal channel body with a floor and with side walls and first connection elements at first ends of the channel body, which can be connected to corresponding second connection elements at second ends of the channel body, the first connection elements being integral with the channel body are trained. In this way, simple manufacturability as well as simple assembly are ensured at low costs, and the first connection elements engage via engagement sections in recesses or projections of the side walls when the gutter bodies are placed against one another in such a way that the gutter bodies are secured to one another in a direction perpendicular to the floor.

The second connection elements can preferably be brought into engagement with the first connection elements and the side walls of the channel body in such a way that the first connection elements in a longitudinal direction of the Channel body are secured to the side walls. This also leads to a simple construction as well as a simple assembly.

The first connection elements engage via offset portions in the recesses or the projections of the side walls when gutter bodies are placed against one another in such a way that the gutter bodies are secured to one another in a direction perpendicular to the floor. So already existing elements are used here for vertical adjustment of adjacent channels.

The side walls have slots countersunk from an upper side of the channel in such a way that second connection elements can be used both for connecting adjacent channel bodies and as protection against spreading out against spreading of the side walls. Here, too, a single element is used for two different functions (in this case, as an expansion protection).

The first connection elements can preferably be bent towards one another via defined bending areas in such a way that end plates can be placed on a channel end. This means that one and the same gutter body or gutter elements can be used both for those gutter elements that are arranged in the middle of a gutter strand and for the end gutter sections, whereby only a slight change to be made at the installation site by bending the connecting elements and the subsequent one Attachment of the end plates is necessary.

In particular, the end plates have first connection elements for connection to the side walls. The construction of the connection between two channel bodies within a channel strand and an end plate with a channel body is therefore identical.

The second connection elements have latching slots which are designed to expand in two stages in such a way that a side wall can be inserted in a first, upper insertion area and a side wall plus a first connection element in a lower insertion area. In this way, one and the same component, namely a second connection element, can be used to connect two channel sections and (in particular in the case of higher tread load on a gutter) can be used to prevent the two side walls from spreading.

The side walls are preferably designed to diverge from one another in such a way that two or more channel bodies can be stacked partially nested. This facilitates storage and transportation.

The side walls preferably have cross-sectionally U-shaped (in the form of an inverted U) closing elements at their upper edges with respect to the floor, which are configured in such a way that a grate or similar covering element can be fitted. This results in a versatile use, in particular when these end elements are designed in accordance with drainage channels as are customary for surface drainage.

It is advantageous here if an outer leg of the end element opposite the side wall (in each case naturally with both end elements) is bent inwards towards the side wall in such a way that a lower edge of the outer leg of an upper gutter body with gutter bodies stacked on top of one another on a end element of a lower gutter body lies on. This ensures that the side walls, which converge downwards in a wedge shape, are not in close frictional engagement with one another, so that jamming can occur. Rather, the distance between the channel bodies when stacking in the vertical direction can be defined by the height of the outer leg.

The side walls preferably have bending tabs which are designed such that, after bending out of the side wall, a puncture channel can be applied transversely to the longitudinal direction of the channel. This increases the variability of the overall arrangement. The lower edges of these bending tabs are preferably beveled in the direction of their ends in such a way that when they are bent out of the (inclined) side wall, the lower edges or their end edges do not pose any danger for cover films or the like located under the channel body.

The connection elements are preferably provided as stripping parts, in particular in the bottom of the channel body. On the one hand, this facilitates the producibility, since no additional sheet metal parts have to be produced. Storage and transport are also facilitated thereby, the arrangement preferably being such that the connection elements can be broken out without any tools by bending back and forth several times.

Any flat material that can be permanently deformed by hand, in particular sheet metal, is suitable as the material.

In the following description, the same reference numbers are used for the same and equivalent parts.

In FIG. 1 Two trough bodies 10 are shown placed against each other, each having a bottom 11 and side walls 12, 13. The side walls 12, 13 are provided with slots to collect and drain water from the surrounding soil. In the figures, the end of a channel body protruding toward the front is designated as the first end 14 and the end protruding toward the rear as the second end 15, as is evident in particular from FIG. 7 emerges.

At their upper edges 17 (see FIG. 3rd ) have the side walls 12, 13 end elements 18 which - together with the side walls 12, 13 and outer legs 19 - have a cross section in the form of an inverted U. Commercially available channel covers can be placed on these end elements 18.

Furthermore, slots 16 are provided in the side walls 12, 13, penetrating parts of the end elements 18. Second connecting elements 30 (see in particular FIGS. 4th and 5 ) are used. These second connection elements 30 have - symmetrically - snap-in slots 31 which have an upper narrow insertion area 32 and a lower, further insertion area 33 (see FIG. 5 ).

How especially out FIG. 3rd emerges from the side walls 12, 13 protrude first connection elements 20 in the longitudinal direction of the channel body 10, which are integrally formed on a bending area 22 on the side walls 12, 13, which is formed by a slot or other such weakening of material. Furthermore, an offset portion 21 is formed between the bending region 22 and the first connection element 20, which elevates the first connection element 20 by approximately one material thickness of the side wall 12, 13 from its plane. Then if two channel bodies 10 as in the FIGS. 1 or 6 shown, are placed next to each other, the second connection elements 20 of the rear channel ( FIG. 1 ) on the outer surfaces of the side walls 12, 13 of the front channel (see also FIG. 6 ).

Furthermore, the first connection elements 20 have slots 23, as can be seen in particular FIG. 3rd emerges.

If now two channel body 10, as in FIG. 1 are shown, placed next to one another and the first connection elements 20 lie on the outer surfaces of the side walls 12, 13, the slots 23 of the first connection elements 20 are aligned with the slots 16 in the side walls 12, 13. A second connection element 30 is now inserted into these slots inserted above, so that the inner edge of the locking slot 31 rests on an inner surface of a side wall 12 or 13. A region of the side walls 12, 13 which adjoins the slot 16 downwards is closely located in the upper insertion region 32 of the snap-in slot 31. The regions of the first connection element 20 lying on a side wall 12, 13 are in turn located in the lower insertion region 33, which is therefore two sheet metal thicknesses and is shaped so beveled in its lowermost area that it is easy to insert from above by gripping the first connection element 20. This is particularly evident from the FIGS. 5 and 6 forth.

In FIG. 1 two such second connection elements 30 are shown in the middle between the two channel bodies 10. The left of the two connection elements 30 encompasses both the side walls 12, 13 and the connection elements 20, while the right connection element 30 only fixes the side walls 12, 13 to one another. In both cases, however, spreading apart of the side walls 12, 13 is prevented by the second connection elements 30.

The second connection elements 30 can be manufactured and supplied as separate components. In the preferred embodiment shown here, however, the second connection elements 30 are provided as partially punched-out parts in the bottom 11 of the channel body 10, which are broken out if necessary. In this way, the manufacture and transport of the entire gutters are made considerably easier.

The first connection elements 20 together with the second connection elements 30 not only form a tensile connection between two channel bodies 10 (as in FIG FIG. 1 shown). It is namely in the second ends 15 of the channel body 10, as shown in particular in FIG. 2nd is shown, recesses 40 are provided which correspond in length to the height of the first connection element 20, in particular in its offset portion 21. When gutter bodies 10 are placed against one another, this offset portion 21 is seated in the recess 40 (on the side walls 12, 13), as is particularly the case in FIG FIG. 6 is shown. Vertical insertion of two channel bodies 10 fastened to one another is achieved by this insertion into one another.

The end of a channel body 10 is formed by an end plate 50, which in particular in FIG FIG. 11 is shown in perspective. Such an end plate 50, like the first ends 14 of a channel body 10, has first connection elements 20 with slots 23. In order to connect such an end plate 50 to a channel body 10, the first connection elements 20 at the first end 14 of a channel body 10 are bent inward by bending the bending region 22 by approximately 90 ° to the side wall 12, 13. Then an end plate 50 is placed in such a way that its foot 51 lies on the floor 11 (see FIG. 1 ) and the first connection elements 20 rest on the outer sides of the side walls 12, 13 such that the slots 23 of the first connection elements 20 of the end plate 50 are again aligned with the slots 16 in the side walls 12, 13. Then a second connection element 30 is inserted from above into the slots 16 and 23, as a result of which the end plate 50 is fixed to the channel body 10 and at the same time the side walls 12, 13 are secured against spreading apart.

In the side walls 12, 13, bending tabs 41 are also provided, which can be bent outwards if a narrow connecting web is cut between them. A spur line (not shown here) can then be connected to the opening. The lower edges 42 of these bending tabs 41 are chamfered in such a way that when they are bent out, the lower edges 42 stand slightly upwards relative to a foil base (in the assembly position) under the channel bodies 10 without sharp edges, so that such a foil base is also not injured.

In order to be able to stack the channel bodies into one another in a space-saving manner in such a way that disassembly is simply possible and jamming is practically impossible, as in particular in FIGS FIGS. 7 and 8 shown - the side walls 12, 13 inclined relative to the floor 11 by an angle α which is greater than 90 °. Compared to the end element 18, which runs parallel to the floor 11, the side walls 12, 13 are inclined by the same angle α (greater than 90 °). The outer leg 19 of the end element 18 in turn is arranged essentially parallel to the side walls 12, 13, so that there is a bending angle of β less than 90 °. This ensures that the lower edge 42 of the outer leg 19 is seated on the end element 18, which is essentially parallel to the base 11, when stacked. This seating ensures that an upper channel body, which is inserted into a lower channel body, does not rest with the outer surfaces of the side walls 12, 13 on the inner surfaces of the side walls 12, 13 of the channel body 10 underneath, which leads to bending and also jamming the channel body 10 stacked one inside the other could lead.

It follows from the above description that great importance is attached to the one-piece design of the channel body with all its elements up to the break-out molding of the second connection elements 30. This leads to considerably simplified production, warehousing and transport.
