DETAILED DESCRIPTION

In the following description of the figures and in the figures, functional elements that have a comparable or the same function are provided with the same reference signs.

FIGS.1to9and10to12illustrate different embodiments1,5,7and8of a wall element that serves for vertical greening. The wall elements1,5,7and8illustrated here have at least one wall component2that is oriented in a vertical or in a diagonal direction and delimits a cavity4, fillable with planting substrate3, of the wall element1,5,7,8. The at least one wall component2has a multiplicity of planting openings6through which planting openings6the plants that are rooted in the planting substrate3can grow onto the side of the wall element1,5,7,8facing away from the planting substrate3.

The at least one wall component2of the wall elements1,5,7,8has a slatted grating that serves as a wall component and is formed from groups of mutually crossing bars9,10of which a first group or spaced-apart parallel bars9is oriented in a vertical direction and of which a second group of spaced-apart parallel bars10is oriented in a horizontal direction. Here, the planting openings6are each bounded by adjacent horizontal and vertical bars9,10.

It is apparent from the longitudinal section inFIG.4that the bars10oriented in the horizontal direction are angled obliquely upward toward the outer side of the wall element1,5,7,8and that the external longitudinal edge of the bars10oriented in the horizontal direction protrudes beyond the bars9oriented in the vertical direction. This is also the case for the wall elements1shown inFIGS.10to12.

It is clear fromFIGS.1,2,5, and8and9, and10to12that the slatted grating provided at least in a subregion of the at least one wall component2is surrounded at its outer periphery by a frame11.

The slatted gratings used as in each case one wall component2may be produced from a non-metallic material and, for example, from plastic. By contrast, the wall components of the wall elements1,5,7and8, and10to12are produced from a metallic material. Here, the slatted gratings are each in the form of pressed gratings, in which the bars9oriented in the vertical or diagonal direction serve as supporting bars and in which the bars10in the form of filling bars and oriented in the horizontal direction have been inserted into indentations12in the supporting bars9. In the case of the wall element1illustrated inFIGS.1to4, the at least one slatted grating serving as a wall component2is held on a wall13and at a distance therefrom. The cavity4provided between the wall13and the wall component2in the form of a slatted grating is fillable with a planting substrate3. It is apparent fromFIG.4that an insulating layer14that extends over the entire area can be provided between the planting substrate3located in the cavity4of the wall element1on one side and the wall13on the other side. This insulating layer14may be moisture-impermeable in order to protect the wall13against the moisture present in the planting substrate3and against the roots of the plants in the wall element1. In addition or alternatively, the insulating layer14may also have a thermally insulating function which protects the roots, located in the planting substrate3, of the plants from input of heat or cold from the wall13.

In order for it to be possible to fasten the slatted grating serving as a wall component2to the wall13, supporting elements15are provided in the corner regions of the preferably rectangular and in particular square wall component2. These supporting elements each have a wall-side fastening flange, from which a bar that serves as a spacer protrudes in a horizontal direction. At the free bar end of the supporting elements15, the wall component2in the form of a slatted grating is able to be inserted with an exact fit and is able to be fixed by way of bolts, expandable split pins, screws16or similar fastening means.

It is apparent fromFIG.3that the cavity delimited by the wall component2can be closed laterally, at the top or—as here—at the bottom by separating plates17. It goes without saying that a plurality of such wall elements1formed from the supporting elements15and a wall component2can be arranged alongside and above one another on a wall. As a result of the insertion of corresponding separating plates17, the cavities of these wall elements1can also be separated from one another. While planting substrate can be introduced into one wall element1in order for plants to be able to grow through the planting openings6in the wall component2, it is also possible for stones to be filled into the cavity4of an adjacent wall element1, which form a wall structure in which lizards or other animals can find refuge. It is also possible to introduce tubular, preferably vegetable material into the cavity4of such a wall element1such that the openings, oriented in the horizontal direction, of this tubular material can serve as a possible nesting site for insects.

The wall elements5,7shown inFIGS.5to7have at least two spaced-apart stand elements18in the form of precast concrete parts which18have at least one slot19,20in their narrow sides that face one another and are oriented in the vertical direction, in which slot19,20at least one wall component2is held.

The slots19,20of the wall elements5,7are in the form of guide slots here, into which guide slots19,20the at least one wall component2can be inserted preferably from above.

It is clear from a comparison ofFIGS.5and6, for the one part, andFIG.7, for the other part, that the stand elements18of the wall elements5,7are configured identically. A guide slot19is formed in each case into the narrow side of the stand elements18in the form of cast concrete parts. This guide slot19in the stand elements18is dimensioned such that a wall component2is insertable into this slot19. If two spaced-apart wall components2that delimit a cavity4between one another are intended to be held at the vertical narrow edges of the positioning elements18, a metal profile is able to be inserted into the slot19of the precast concrete parts that serves as stand elements18, said metal profile subsequently forming an enlarged guide slot20into which it is also possible to insert two spaced-apart wall components2.

In the case of the wall element8shown inFIGS.8and9, two vertical profile bars21are provided, which serve as stand elements and each have a guide slot22on their mutually facing sides. At least one wall component2in the form of a slatted grating is insertable into this guide slot22of the profile bars21. The wall component2, in the form of a slatted grating, of the wall element8also delimits a cavity (not shown in more detail here) which is fillable with a planting substrate.

FIG.10shows a greenable wall element1which has wall components2of the type described above, which are oriented obliquely, i.e. in a diagonal direction deviating from a vertical direction, on a visible side of the wall element1. The wall components2of the wall element1shown inFIG.10are connected via supporting elements15to a stand element18of the wall element1.

A cavity4is formed between the supporting element18and the wall components2in this wall element1, too, and this cavity, as for example inFIG.4in the case of a wall element1having vertically oriented wall components2, can be filled with a planting substrate.

The wall element1shown inFIG.10comprises, as a stand element18for fastening the wall component2, an L-shaped concrete element24which in this case adopts the function of a wall and serves as a support for the wall components2.

FIG.11shows a wall element1with diagonally oriented wall components2on a front side26and vertically oriented wall components2on a rear side27facing away from the front side26.

The wall element1shown inFIG.11can be used for example as a noise protection wall. The wall components2on the front side26of the wall element1are arranged in a manner spaced apart from the wall components2on the rear side27of the wall element1such that the wall components2on the front side26delimit, with the wall components2on the rear side27, a cavity4which can be used in turn to receive a planting substrate3.

The wall components2arranged on the front side26are connected by connecting elements25, in this case by connecting profiles, to the wall components2on the rear side27of the wall element1.

Each of the wall components2of the wall element1shown inFIG.11has a rectangular, square cross section. A wall element1of virtually any desired size can be configured from a plurality of such wall components2.

FIG.12shows a further embodiment of a wall element1which can be greened both on its front side26and on its rear side27. For this purpose, the wall element1according toFIG.12has, both on its front side26and on its rear side27, wall components2which are connected together by connecting elements25. Here, the wall components2on the front side26and the wall components2on the rear side27of the wall element1are oriented diagonally with respect to a standing surface of the wall element1such that they together define an acute angle. Formed in turn between the wall components2on the front side26and those on the rear side27of the wall element1is a cavity4into which a planting substrate3can be filled, as is also shown in the illustration according toFIG.12.

The wall elements1shown inFIGS.11and12form, by way of their wall components2connected together via connecting elements25, a self-supporting structure which does not require any other supporting structure such as a wall13or a concrete element24to which the wall components2would need to be fastened.

The wall elements1shown inFIGS.10to12each comprise a plurality of wall components2which are each formed from a slatted grating. The slatted grating of the diagonally oriented wall components2is formed from groups of mutually crossing bars9,10of which a first group of spaced-apart parallel bars9is oriented in a diagonal direction in the use position of the respective wall component2and of which a second group of spaced-apart parallel bars10is oriented in a horizontal direction. Here, the planting openings6are each bounded by adjacent horizontal and diagonal bars9,10.
