Description

Noise protection element and noise barrier

[0001] The invention relates to a modular noise protection element, in particular a green noise protection element, with a plurality of spaced posts for receiving at least one wall part, wherein the posts are adapted to laterally surround each wall portion in the region of a front side with a receiving profile, and with elastic Clamping elements for fixing each wall part relative to the post.

The invention further relates to a noise barrier with at least one such noise protection element.

Such a noise barrier is known from EP 1 455 018 AI.

CONFIRMATION COPY These are a noise barrier with posts, which are designed to hold several noise protection cassettes. The noise protection cassettes are supported on the front side by means of elastically deformable spacers relative to the posts.

From DE 295 10 861 Ul a similar noise barrier is also known, wherein wall elements can be fixed by means of rotatable eccentric to post profiles. For clamping the wall elements, the eccentric can be actuated from the outside.

Noise barriers with the aforementioned noise protection elements are often provided along traffic routes or for shielding other noise-intensive objects. They can serve to protect local residents or passers-by from excessive noise pollution from such noise sources.

For aesthetic reasons and to promote biodiversity and the creation of green spaces, especially in urban areas, noise control elements are often provided for extensive or intensive greening.

Extensive greening can be done to the effect that on the noise protection elements suitable adhesive or rank structures are provided to allow the attachment and climbing of plants that are planted in the ground next to the noise barrier.

Intensive greening is done by greening the noise barrier itself, such as by planting tub or the like to accommodate a substrate in the noise barrier are arranged.

The greening of a noise barrier can in addition to the mere aesthetic effect and influence on the sound insulation, reflection or absorption to have. In addition, green noise barriers can also contribute to CO ₂ absorption.

Against this background, the object of the invention to provide a noise protection element and a noise barrier with several noise protection elements, which can be easily manufactured and very light, fast and flexible, also characterized in use by a high degree of robustness and to changing environmental conditions should be insensitive. The noise protection element or the noise barrier should be suitable as possible for greening.

This object is achieved in a noise protection element according to the aforementioned type according to the invention that the elastic clamping elements set the at least one wall part perpendicular to its surface extension on the receiving profile of the post under bias.

The object of the invention is completely solved in this way.

In fact, according to the invention, each wall part can be mounted particularly easily and quickly by means of the elastic clamping elements. Here, the wall parts in the longitudinal direction, ie along their areal extent, not or hardly burdened by clamping or clamping forces. Consequently, the wall parts can be particularly simple.

Are the posts designed as U or H profiles, so the wall parts are effectively clamped or secured between legs of each post. It should be noted that this embodiment allows a relatively rough tolerancing of the distance of the posts to each other, since the wall parts are not fixed or clamped in the direction of their end faces, but in the region of their end faces, but perpendicular to its longitudinal extent. The extension of the legs specifies the tolerance range for the assembly. The distance two legs of said profiles, however, tolerated with sufficient accuracy, so that with elastic clamping elements secure attachment of the wall parts is possible. Thus, the posts can be arranged very quickly and easily without special accuracy requirements when setting up the noise protection element.

In the context of the invention it is possible, each wall part only with two fasteners, namely one per post, to be able to set.

[0017] In an advantageous embodiment of the invention ^{^} the resilient clamping elements have a direction-dependent acting spreading means which can be mounted in a preferred mounting direction and have an increased spreading action in a reverse direction.

By this measure, the assembly can now be particularly simple, namely by feeding the wall part and attachment of the elastic clamping elements done. Here, the elastic clamping elements need only with a force, such as hammer blows or the like, to be acted upon, however, disassembly can be done only with increased effort. A release of the elastic clamping elements with a hammer can be prevented. The assembly system is particularly safe, damage due to theft, vandalism or the like can be avoided.

In an advantageous embodiment of the invention, the elastic clamping elements are held positively in the assembled state.

In this way, a firm connection between the wall part, the post and the elastic clamping elements can result, a rattling or loosening can be prevented. Nevertheless, with a non-positive connection still a certain tolerance compensation can be made, for example, to compensate for temperature fluctuations and related changes in length. A certain residual elasticity also has the advantage that vibrations, such as sound waves, can be absorbed particularly well by a flexible structure in dimensions.

According to a further embodiment of the invention, the elastic clamping elements are held in the assembled state via locking means additionally or exclusively positively.

By this measure, an additional safeguard against disassembly can be effected. During assembly, the engagement of the elastic clamping elements can result in a clear feedback to the fitter, so that the installation of the noise protection element further simplified.

In an advantageous embodiment of the invention, the elastic clamping elements are formed using a strip material or a wire material, in particular of a spring steel.

Thus, the elastic clamping elements can be particularly simple, for example, by bending or winding processes, manufactured and designed to be particularly robust. When using a spring steel can be ensured that the bias of a mounted elastic clamping element over time is not or only slightly degraded.

When using a stainless spring steel, such as a stainless steel, the longevity of the mounted noise protection element can be further improved, in particular, a desired disassembly of the elastic clamping elements can still be made possible even after a long time.

According to a further embodiment of the invention, the elastic clamping elements consist of a plastic material. Also in this way, the elastic clamping elements can be made very easy and protected against corrosion.

Resilient clamping elements made of plastics can be injected into molds, cut to length from extruded profiles or thermoformed from a strip material. It is understood that the plastic material may have plastic or elastomeric properties at least within limits.

In this context, it should be noted that the elastic clamping elements can also consist of a combination of metallic materials with plastic materials. For example, a support structure made of a spring steel and be provided with a plastic coating, so that the directional dependence of the spreading is further enhanced. Here, the plastic coating may have approximately a directional profile.

In an advantageous embodiment of the invention, the elastic clamping elements on a base leg and a spreader leg, which act on each other in the assembled state.

In this way, a closed power flow can result within the elastic clamping elements, so that adjacent components are not excessively acted upon.

On the design of the base leg and the spreader leg, the force required for assembly or disassembly force can be influenced. If it is intended to clamp a component between the base leg and the expansion leg, the relative movement of the elastic clamping elements relative to the component during assembly or disassembly effects a different spreading action. In a preferred embodiment of this embodiment, the base leg and the expansion leg of a flat band are formed like a clip and connected by at least one flat piece and deflection.

Thus, the elastic clamping elements can be made particularly simple, since only bending operations have to be done in a plane. Together with the required cutting to length of the flat strip, a particularly fast, process-reliable and inexpensive production can result.

Preferably, the expansion leg is rounded in an end region which faces the base leg. Since this end region slides during assembly along the component to be clamped, a rounding of the end region can bring about a further simplification of the assembly.

Alternatively, the expansion limb may have a sharp-edged end region, which may result in a slightly higher assembly forces, but nevertheless significantly increased disassembly forces. In particular, in such an embodiment, dismantling may only be destructive.

According to one embodiment of the invention, each wall part on its lateral end faces frame parts with stop surfaces, which are clamped by means of the elastic clamping elements in the frontal opposite mating surfaces of the receiving profiles of the posts, which engage around the wall part laterally.

By this measure, the wall parts can be further relieved. Essentially, the frame parts are subjected to the posts, so that a force flow wall part - post - elastic clamping element can result. The mechanical load on the wall parts can be further reduced, so that the structure of the wall parts can be further simplified. It is also particularly preferred that in this embodiment, in which the frame parts are clamped by means of the elastic clamping elements in the receiving profile of the post, the elastic clamping elements are covered by the legs of the posts, so that an unwanted manipulation from the outside is further difficult ,

According to a further embodiment of this embodiment spacers are provided between the posts and the frame parts of the wall parts, which engage the elastic clamping elements.

As a result, the wall parts can be particularly easily adapted to different post dimensions, namely different distances between the legs of the post. It can thus be possible to build with only a width of wall parts noise barriers with a variety of posts, if appropriate spacers between the frame parts and the post are used.

In this embodiment, a closed power flow frame part spacer - elastic clamping element - post can be effected so that the burden of the clamped wall part in the direction of its longitudinal extent does not increase or only slightly.

In an alternative embodiment of the invention, each wall portion is fixed by the elastic clamping elements which engage on one side of the wall portion in one direction to the post, wherein on the other side deformable contact elements are provided by the elastic clamping elements in the direction the opposite mating surface of the receiving profiles of the posts are acted upon. This measure can also serve to compensate for tolerances, for example, an excessive clamping force can be reduced by deformation of the contact elements.

The contact elements may be formed approximately as elastomer profiles. A particularly high deformability of the contact elements can be effected by recesses or cavities, which can be taken into account in their design. Preferably, a receptacle, more preferably an undercut receptacle, such as a Christmas tree profile, is provided for the contact elements on the frame part.

In a preferred embodiment of the invention, each wall part of the upper edge surfaces ceiling profiles and bottom edge surfaces on soil profiles, which interlock positively.

In this way, a wall part which is placed on a ceiling profile, already be aligned by the positive connection between the ceiling profile and the floor profile so far that this wall part is already sufficiently fixed by the attachment with two elastic clamping elements, thus fully assembled ,

In a preferred embodiment of this embodiment, at least the ceiling profiles or floor profiles centering or insertion aids in the form of inclined surfaces.

By this measure, a further improved installation of the noise protection element can result, since in the placement of the wall part this can be centered automatically.

[0050] According to a further embodiment of this embodiment, an upper end profile is provided which, by means of a snap connection, projects onto the ceiling elements. profile is placed, with locking lugs and thus corresponding locking members are provided.

In this way, a noise protection element can be completed particularly easily without additional mounting aid upwards. The end profile can protect the noise protection element to a great extent against environmental influences, such as rain, snow or sunlight.

By means of the end profile may also be effected a conclusion of the post upwards, so that the elastic clamping elements that define each wall part of the post, are even better protected against manipulation from the outside.

Alternatively, the end profile can also be formed across posts, that is to cover the posts. It can thereby save separate caps for the posts, the security against manipulation and protection against environmental influences can be further increased.

In an advantageous embodiment of this embodiment, the locking lugs on the ceiling profiles and the locking members are provided on the end profile, wherein the locking members are preferably formed as locking springs and are accommodated in recordings of the end profile.

Thus, the end profiles can be very easily attached only by pressure from above. This type of attachment may be inaccessible from the outside, therefore tamper-proof or theft-proof.

According to a further embodiment of the invention, each wall part at least one noise protection plate made of an insulating material, preferably a fibrous or porous insulating material, more preferably mineral wool or rock wool, on. In this way, a particularly high insulation, in particular absorption capability, can result. Such a designed noise protection element is particularly suitable for greening.

Plants can adhere and climb particularly well to the noise protection plate, there is also a certain ability to absorb and deliver water, which can serve to supply the plants.

The insulating material may also comprise natural fibers, such as thatch, seaweed, coconut, bamboo or hemp fibers. Likewise fibers made of recycled plastic are conceivable.

It is understood that the insulating material can be used both extensively and with intensively plantable noise protection elements.

In an advantageous embodiment of this embodiment, the noise protection plates are fully covered at the top and bottom edge surfaces of at least the ceiling profiles or floor profiles, with part of the upper and lower edge surfaces of cavities is limited, such that there is ventilation and drainage of the noise barriers ,

This measure has the advantage that excess water, such as continuous rain, can run off or evaporate, so that harmful effects on the planting or the components of the noise protection element can be avoided. Air circulation and drainage, while accepting some water absorption capability of the noise barriers, may facilitate the feasibility of the noise control element. In particular, the effort to care for the greening of the noise protection element can be significantly reduced. In a preferred embodiment of the invention, the noise protection plates are completely covered on the front sides of the frame members, but only a portion of the end faces is contacted directly, such that there is ventilation and drainage of the noise barriers.

Also by this measure, an air circulation can be promoted and a water removal can be supported, so that the durability of the noise protection element and the greening can be further improved.

According to one embodiment of this embodiment, the noise protection plate is completed by a frontal grid arrangement at least front or rearward to the outside, preferably, the grid assembly is connected to the ceiling profile and the bottom profile.

Thus, the stability of the insulating material and the cohesion of the wall part can be maintained. Furthermore, the grid arrangements can give additional support to a planting and consequently further improve the feasibility of the noise protection element.

It is particularly preferred in this case if the grid arrangements comprise vertical grid bars and horizontal grid bars, wherein the vertical grid bars have larger cross sections than the horizontal grid bars.

In this way, the noise protection element can be particularly well adapted to possible wind loads with optimal use of material that can act on the noise protection element in use. It has been found that in grid arrangements which have a higher resistance momentum in the vertical than in the horizontal, a particularly high resistance to wind pressure can result. Consequently, material can be saved in the design of the grid assemblies in the horizontal. Thus, it may also be possible to be able to build very high noise barriers without additional reinforcements. Preferably, the vertical bars are connected via flat profiles with the ceiling profile and the bottom profile, so that the wall part on all sides, namely by the ceiling profile, the bottom profile, the frame parts and the grid arrangement, edged or can be completed.

Thus, an improved inherent stability of the wall portion and improved ability to receive and dissipate loads may result.

According to a further embodiment of the invention, at least one wall part on a planar photovoltaic device which closes the at least one wall part frontally in one direction.

By this measure, both a one-sided greening and, on the other hand, a recovery of energy from sunlight with a suitable location and orientation of the noise protection element.

Advantageously, in this case the end profile also serve to cover the necessary wiring. For this purpose, cable guides may be provided on the end profile. It is particularly preferred if elements of the photovoltaic device can be exchanged in a completely assembled noise protection element without the wall part itself having to be dismantled.

In an expedient development of the invention, a compensating element is provided in the bottom area, with a horizontally oriented connection profile which corresponds to the ceiling profile into which a bottom profile of a wall part can engage in a form-fitting manner.

In this way, a leveling of the substrate can be carried out, so that even with uneven floors a particularly simple and fast mountability of the noise protection element is ensured. Thus, justification work before the actual installation of the noise protection element on the setting of the posts, such as in a prepared foundation, and the design and alignment of the compensating element can be limited. In this case, essentially only the horizontal alignment of the compensating element is to be carried out with sufficient accuracy. As mentioned above, the distance between the posts can vary within certain limits. After such a rationale, the noise protection element can be installed and completed in a modular manner or modular manner in a short time. There are no further alignment or Justiervorgänge required.

The compensating element may be used directly on site, e.g. Concrete, molded or prefabricated. It is also conceivable to make the compensating element adjustable by means of suitable adjustment means, such as threaded feet or the like, in order to be able to carry out its assembly particularly quickly without elaborate preparation. Alternatively, it is possible to dispense with adjustment means in the compensation element, for example, with exactly leveled point foundations.

According to a development of this embodiment, the compensation element is fixed by means of the elastic clamping elements on the post.

Thus, the compensation element in the context of or after leveling analogous to the wall parts are particularly fast and easy to be fixed to the post.

In an advantageous embodiment of the invention, the noise protection element has a plurality of superimposed wall parts, which are each fixed in the upper region by means of elastic clamping elements on the post.

In this way, particularly high noise protection elements can be realized. It is conceivable that between two superimposed wall divide decorating elements or the like provided. The noise protection element can also be flexibly adapted to the posts and other requirements when using wall parts which have only a few different heights or even only a characteristic height.

It is understood that with noise protection elements according to the invention a noise protection wall can be constructed almost any longitudinal extent and height. The noise barrier can, but not necessarily, have noise protection elements according to various embodiments of the invention, so that needs specific fast availability, easy installation in a short time and adaptability to different conditions of use with high robustness and longevity can be effected.

It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.

Further features and advantages of the invention will become apparent from the following description of preferred embodiments with reference to the drawings. Show it:

10 is a frontal view of a noise protection element according to the invention.

In Fig. 1, an inventive noise protection element is shown in its entirety and designated 10 in total.

The noise protection element 10 has two posts 12, which may be embedded in foundations 14 (not shown here, see FIG. 10). It is understood that the post 12 can be anchored in a suitable substrate just as directly, for example by ramming.

The posts 12 are presently designed as H-profiles. In this way, noise protection elements 10 according to the invention can be particularly easy to a Noise barrier be expanded. To complete such a noise barrier, it is advisable to provide posts with U-shaped profiles on the side edges.

Between the posts 12, a wall portion 16 is received. The wall part 16 is frontally closed by a grid assembly 18 to the outside. It is understood that the grid assembly 18 may be provided both front side and rearward on the wall part 16.

In the floor area, the noise protection element 10 has a compensating element 20, which is used as a grounding and position fixing of the wall part 16.

The compensating element 20 may be cast, for example, together with the foundations 14 of the posts 12, made of concrete or the like. In this case, it is conceivable on the one hand to produce the compensating element 20 directly on site, so that a height alignment can be carried out particularly easily taking into account the on-site conditions.

Alternatively, it is conceivable to prefabricate the compensation element 20 in a manufacturing facility, to spend at the installation site and to level by simple means, such as a spirit level, when setting up suitable.

As will be explained below, after setting the posts 12 and the compensating element 20 during assembly of the noise protection element 10 no further essential work for alignment or adjustment is required.

The definition of elements of the wall part 16 on the post 12 will be explained below with reference to FIGS. 2 and 3. The wall part 16 has at least one noise protection plate 22 (see also Fig. 4), which are fixed by means of frame members 24, which are arranged on end faces 26 of the noise protection plate 22 in receiving profiles 28 of the posts 12.

For this purpose, the frame part 24 is fixed to the post 12 using an elastic clamping member 30. This is done according to FIG. 2 directly, while Fig. 3 shows an embodiment in which the determination is realized indirectly using a spacer 32.

By means of the spacer 32, which is embodied here as a simple rectangular profile, the noise protection element 10 according to the invention can be constructed without special measures for adapting the frame parts 24 to the dimensions of the posts 12 would be required. The frame parts 24 are preferably made of extruded profiles made of a metallic material, in particular of aluminum or an aluminum alloy, so that as few variants as possible are to be produced in order to promote the profitability of the method. Consequently, it is desirable to use only one profile size that is usable both on the right and left sides of the noise protection plate 22, and to allow adaptation to different sizes of posts 12, in this case the spacing of legs between which the frame parts 24 are received. This is done in a simple manner by spacers 32, which can be produced in a modular manner in different sizes with little effort, procured and kept.

An attachment and securing of the wall portion 16 in the post 12 can be done easily and quickly by inserting the elastic clamping elements 30, which can be driven, for example by means of a hammer. It can be seen that the noise protection plates 22 are not directly impacted by the clamping force which secures the connection of the wall part 16 to the post 12 itself. On the contrary, in FIG. 2, a short, closed adhesion occurs along the frame part 24 of the elastic clamping element 30 and of the post 12. According to the above statements, the spacer 32 is additionally subjected to the clamping force in FIG. 3.

The noise protection plate 22, which is formed for example of a porous or fibrous material, does not experience even this high clamping force, so that no special measures required to stabilize the noise protection plates 22 despite the use of insulating materials, which generally have high strength are. However, the posts 12, the frame members 24 and the elastic clamping elements 30 can be designed so that there is a high clamping force, on the one hand to secure the attachment of the wall portion 16 and on the other to prevent manipulation or disassembly by third parties.

4 shows a vertical section through an inventive noise protection element 10, wherein the illustration of the posts 12 and the lateral frame parts 24 has been omitted for reasons of clarity.

In the present case, the noise protection element 10 has two wall parts 16 arranged one above the other, shown discontinuously. The lower wall part 16 is arranged on the compensation element 20. To fix the position, alignment and ease of assembly, a ceiling profile 34 and a bottom profile 36 are provided on each wall part 16. The ceiling profile 34 and the bottom profile 36 may advantageously be formed as extruded components of an aluminum material. Alternatively, it is conceivable to produce these parts from sheets by bending or similar forming processes.

As an insertion aid and for centering 34 inclined surfaces 40 and the bottom profile 36 inclined surfaces 42 are formed on the ceiling profile. Thus, a wall portion 16, which is usually supplied from above by insertion into the receiving profiles 28 of the posts 12, for example, by merely lowering to an already mounted wall portion 16 are aligned. Preferably, the inclined surfaces 40, 42 have a shape that allows such a large mounting game that the to be mounted wall part 16 without additional guidance during installation always safe and accurate on an underlying ceiling profile 34 can come to rest. Accordingly, no special requirements are to be placed on the assembly of the noise protection element 10 according to the invention, provided that the compensation element 20 is correctly aligned. In addition, a high accuracy can be achieved by the pairings brought about by the inclined surfaces 40, 42, which can be achieved by mounting the above-described elastic clamping elements 30 can be easily secured.

As shown in FIG. 4, a ceiling profile 34 is also provided on the compensating element 20. Alternatively, the embodied here by the ceiling profile 34 contour can also be realized directly in the compensation element 20. This is particularly useful when the compensating element 20 is made approximately by prototypes of concrete or the like.

Between the lower wall portion 16 and the upper wall portion 16, an intermediate profile 38 is arranged, which may also consist of an extruded aluminum material and consequently also with inclined surfaces 40, 42 may be provided to be mounted and aligned analogous to the wall portion 16 to be able to.

The intermediate profile 38 can serve the optical design subdivision of the noise protection element 10. Furthermore, height adjustment can be effected with the intermediate profile 38, for instance with a plurality of mutually adjacent noise protection elements 10 set up along a slope, despite the changing height level, a uniform conclusion, namely the same absolute height for each of the noise protection elements 10 to be able to realize. For this purpose, a plurality of intermediate profiles 38 can be arranged one above the other as required. Alternatively, it is conceivable to provide different intermediate profiles each of a certain height.

The noise protection element 10 is at the top by a final profile 44, also produced by extrusion or sheet metal forming completed. The end profile 44 can serve aesthetic purposes and generally the protection of the noise protection element 10 against external influences. Thus, the end profile 44 is suitable, for example, for discharging precipitation, but also for covering the elastic clamping elements 30 (not shown in FIG. 4), which fix the wall part 16 below the end profile 44 to the posts 12. Thus, the elastic clamping elements 30 can not be viewed from the outside or even undesirably manipulated or removed. In this way, an integrated closed, compact shape of the noise protection element 10 can result, so that the likelihood of wanton damage or destruction can be reduced.

The end profile 44 is attached via a rear snap, a snap-in connection, on the underlying wall part 16. For this purpose, latching members 46, in the present case designed as curved springs, are provided. The locking members 46 (see also Fig. 9) are arranged in receptacles 48 of the end profile 44. It is also conceivable to carry out an end profile with integrated locking members in one piece. If this is done in an extruded profile, correspondingly lower elasticities and possible deformation paths of the latching members are to be considered. If the end profile 44 is produced from a sheet metal, for example a sheet steel, by forming, sufficiently elastic locking members 46 can be formed on this sheet metal.

The locking members 46 act in the assembled state with locking lugs 50 which are formed on the ceiling profile 34 of each wall portion 16, together. Here, the inclined surface 40, which is also the recording and orientation of the soil profile Can serve 36, advantageously come as an assembly aid for use. Along the inclined surfaces 40, the locking members 46 can slide, deflected or deformed during assembly of the end profile 44, and then, when the end profile 44 comes to rest against the underlying wall portion 16, snap behind the locking lugs 50.

Also in this connection, it is desired to contrast a particularly simple and quick installation difficult dismantling in order to avoid unwanted manipulation can.

In the area of the inclined surfaces 40, 42, the ceiling profiles 34, the bottom profiles 36 and the intermediate profile 38 are designed such that upon contact with the edge surfaces 52, 54 of the noise protection plates 22 cavities 56, 58 result, over which the noise protection plates 22 effectively can be ventilated and vented. This can be effected particularly easily when using extruded ceiling profiles 34, floor profiles 36 and intermediate profiles 38 without additional manufacturing steps. It should be added that the noise protection plates 22 are formed as compact as possible, for example as a rectangular body, without exposed or filigree structures due to their limited inherent stability.

[Oll i] At the lower edge surfaces 54 of the noise protection elements 16 lower cavities 58 and at the upper edge surfaces 52 upper cavities 56 are present. In this way, despite the preferably porous, fibrous structure of the noise barriers 22, a certain moisture control can be effected by e.g. Run off excess water or in natural air circulation through the cavities 56, 58 can evaporate.

For green noise barriers a certain water absorption capacity of the noise barriers 22 is quite desirable in order to provide moisture to adhering plants can. However, excessive water absorption and storage is to be avoided, since this is quite a Damage to the greening, such as through rot, may result. An excessively damp wall may result in a reduced soundproofing capability. In the noise protection element 10 according to the invention, an automatic ventilation and removal of excess water can be effected despite a high security against manipulation and a closed design.

FIGS. 5 and 6 each show a horizontal section through an inventive noise protection element 10, locally limited to the region of the posts 12.

The posts 12 may for example be designed as steel profiles, such as cold or hot rolled or drawn. Likewise, posts 12 made of extruded aluminum materials, concrete or masonry are conceivable. The posts 12 may also be formed of plastic.

The posts 12 in Figures 5 and 6 differ only in the width of the receiving profile 28. Usual widths may be about 160 mm, 180 mm or 200 mm. In contrast, the frame parts 24 in Figures 5 and 6 have identical outer dimensions.

To fix the frame parts 24 to the post 12 by means of elastic clamping elements 30, not shown here, a certain distance dimension, here indicated by the arrow 68, must result between abutment surfaces 25 of the frame parts 24 and the posts 12, so that the elastic clamping elements 30 can take effect. In order to be able to ensure this dimension 68 even with over-wide posts, as shown in FIG. 6, it is sufficient to provide the spacer 32 on the stop surface 25, in this case a simple rectangular profile, so that the desired dimension for insertion of the elastic clamping element 30 between the post 12 and the spacer 32 may result. At the opposite side of the abutment surfaces 25, the frame parts 24 receptacles 62, in which a contact element 60 is arranged. The contact element 60 is advantageously designed as an elastomer, generally as a deformable body. The receptacles 62 are present undercut for receiving a Christmas tree profile.

The contact element 60 can further improve the ability to compensate for tolerances in the assembly and operation of the noise protection element 10. Furthermore, a vibration decoupling of the wall parts 16 from the post 12 can thus be effected.

Finally, the contact elements 60 can serve to avoid a direct mechanical contact between the posts 12 and the frame parts 24, so that damage, such as scratches, contact corrosion or the like, can be avoided during assembly and operation.

As shown in FIG. 5, the noise protection plate extends over the entire width of the frame part 24. It can be seen that a noise protection element 10 designed in this way can be planted from both sides.

On the other hand, means are provided on the frame part 24 in FIG. 6 for accommodating, in addition to the noise protection plate 22, also other plate-shaped or bar-shaped elements, preferably a photovoltaic device 64. A noise protection element 10 designed according to the illustration in FIG. 6 can thus be from one side while the other side can be used to generate energy. As already mentioned, in this case a wiring through the end profile 44 (FIG. 4) or in a suitable manner by the intermediate profile 38, the ceiling profile 34 or the frame member 24 may be covered and protected against environmental influences or manipulation from the outside. It can be seen from FIGS. 5 and 6 that the frame parts 24 do not directly contact a web 66 of the posts 12. This clarifies that the distance between two posts 12, between which wall parts 16 are to be received, need not be tightly tolerated in the noise protection element 10 according to the invention. The alignment and fixing on the frame parts 24 takes place on legs of the receiving profile 28 of the post 12, the associated amount can be kept in the production of the post 12 readily in a required tolerance range. Furthermore, with the spacers 32, an adaptation of the wall parts 16 to the receiving profile 28 of the post 12 done.

As mentioned above, it can also be explained with reference to FIGS. 5 and 6 that, when the wall parts 16 are fastened to the posts 12, no forces are caused in the longitudinal direction of the wall parts 16, which adversely affect the noise protection plates 22 or the photovoltaic device 64 could affect.

The elastic clamping element 30 according to the invention can be described in more detail with reference to FIGS. 7 and 8.

The elastic clamping element 30 has a base leg 70 and a spreader leg 72. Such elastic clamping elements may be made of strip material, preferably spring steel strips, or of wire material. The embodiment of the elastic clamping element 30 shown in FIG. 7 is also suitable for primary shaping production, for example for plastic injection molding.

In Fig. 8, a mounted elastic clamping member 30 is shown. The base leg 70 and the expansion leg 72 engage around the stop surface 25 of the frame part 24. Furthermore, the expansion limb 72 is supported rearwardly via a flat piece 71 on the post 12.

The elastic clamping element 30 can be completed by simple bending processes in the flow. The base leg 70, one or if a plurality of flat pieces 71 and the expansion limb 72 are connected to each other via deflection regions 69, which represent transitions in the form of radii. Of course, the flat pieces 71 can also be replaced by bent portions, for example to effect increased deformability, but the flat pieces 71 are particularly suitable for mounting with a hammer, since they provide a suitable flat approach surface for the hammer blows.

The expansion limb 72 also has an end region 76, which in the present case can be seen as a radius transition with reference to FIGS. 7 and 8. In order to further increase the spreading effect, in particular when releasing the elastic clamping element 30, the end region 76 can be made sharp-edged in the direction of the base limb 70 or the element to be clamped.

When mounting the elastic clamping elements 30 on the frame part 24 of the expansion leg 72 is deformed in the direction indicated by the arrow 73 direction. In contrast, during disassembly of the elastic clamping element 30, a deformation takes place in the other direction indicated by the arrow 74. It can now be seen that while the clamping action between the base leg 70 and the expansion leg 72 is further enhanced. Thus, a high level of security against disassembly is ensured, the spreading of the expansion leg 72 leads to a power boost, so that when disassembling a higher force than the original clamping force must be overcome.

By suitable surface pairing between the stop surface 25 of the frame part 24 and the expansion limb 72, this effect can be enhanced. Finally, the expansion limb 72 can be designed in its inclination relative to the base limb 70 such that release of the elastic clamping element 30 is only destructive. On the frame part 24 is optionally a locking means, a curvature 75, on or formed, with which the clamping and holding action can be additionally reinforced or hedged. In this case, the elastic clamping element 30 can be secured non-positively and positively. 9 shows, by way of example, a latching element 46, as can be used for fastening the end profile 44 on the wall part 16 (see FIG. The locking member 46 may also be formed of a strip material, in particular a spring steel. For mounting the locking member 46 in the receptacle 48 of the end profile 44 are receiving lugs 77, 78 are formed, which are inserted into the receptacle 48. Advantageously, the receiving lugs 77 are slightly entangled with respect to the receiving lug 78, so that good guidance and clamping of the latching member 46 in the receptacle 48 of the terminating profile 44 can result. Thus, the receptacle 48 of the end profile 44 can be manufactured with larger tolerances, thus with less effort.

Finally, FIG. 10 shows a frontal view of the noise protection element 10 according to the invention. This may be the front side or the rear side. The posts 12 are mounted on the foundations 14, for leveling the compensation element 20 is used. In addition, the two wall parts 16 are arranged, which are interrupted by the intermediate profile 38 and covered at the top by the end profile 44.

The wall parts 16 have on the outside vertical bars 80 and horizontal bars 82, which are the grid assembly 18 associated. It can be seen that the vertical grid bars 80 have larger cross sections than the horizontal grid bars 82. With this configuration, the noise protection element 10 can be particularly well adapted to possible wind loads, the bidirectional structure of the grid assembly 18 leads to a configuration which simultaneously with high resistance material saving is formed.

Alternatively, it is conceivable to use bars with the same cross-sections and to space the vertical bars more closely than the horizontal bars. In general, the vertical moment of resistance of the grid should be greater than the horizontal. For this purpose, rods of different diameters are conceivable. It is understood that such a directional structure can also be effected with suitably perforated or beaded sheets or with corrugated sheets, provided that sufficient openings for ventilation and drainage of the noise protection plates 22 are provided.

The grid assembly 18, together with the porous or color-containing noise protection plates 22, improve the reasonableness of the noise protection element 10, since the plants used for greening can adhere and climb particularly well to the vertical grid bars 80 and the horizontal grid bars 82.

In connection with FIG. 4, it can be seen that the grid arrangement 18 can be connected via flat profiles 84 to the ceiling profile 34 and the floor profile 36 of the wall part 16. In this way, about the vertical bars 80 can act as tie rods and on the one hand improve the cohesion of the wall portion 16, on the other hand dissipate it in the frame structure in the presence of external loads.

In the context of the invention, it has been possible to provide a noise protection element which can be mounted very simply and quickly, in which a high accuracy and rapid alignment of the wall parts 16 with respect to the posts 12 can be realized without great labor and production costs, and that is particularly well protected against environmental influences, especially rainfall, and against manipulation from the outside. The noise protection element 10 is particularly suitable for extensive or intensive greening.
