Abstract

The soundproof wall (1) is formed of stacked and horizontally divided reinforced concrete wall plates (8) which are attached to supports (10). The reinforced concrete wall plates rest on a base plate (9) in connection with a block foundation (14). The photovoltaic modules are arranged on a supporting structure before the soundproof wall. The photovoltaic modules have an attack angle to the horizontal between 35 degree and 45 degree over the supporting structure.

Description

The invention relates to a noise barrier in combination with photovoltaic modules.

The solution according to the invention provides advantages with a view to minimizing the sometimes complicated structure of the surfaces and the volume of construction of noise barriers on the one hand and a simultaneous generation of electrical energy from photovoltaic modules, which are large and inclined in front of a smooth reinforced concrete wall, on the other hand, by the photovoltaic modules traffic noise far above a concrete concrete wall arranged directly behind them.

It is advisable to connect highways, highways and railroad tracks, which have a preferably east-west orientation in urban settlement areas, in addition to the known more or less expensive sound-absorbing traffic structures, with energy-generating photovoltaic modules.

The state of the art ascertainable for this purpose shows a raft of first solutions, which will be explained in more detail below by way of example.

So is after DE 201 09 673 U1 a equipped with solar panels noise barrier known whose traffic noise emitting traffic route from the perpendicular zugeneigte front, is formed of insertable into posts noise protection plates, being arranged at its upper end wall and at right angles to their solar panels. The solar panels rest on supports that are welded to the posts of the noise barrier. The two main elements noise barrier and solar panels here form a mutually conditional unit, which in case of failure of an element, in particular damage the patch solar panels, neither a sufficiently derived sound insulation nor a desired electric power generation can be achieved.

With DE 196 45 683 A1 a noise protection wall with solar modules is presented. The solar modules are glued to the free, upper wall end at a defined angle. Between embedded in concrete foundations columns are superimposed, the top plate and the upper end of the support having a slope which serves to support a solar module to be stuck. The plates are coated with sound absorbing material. Due to the arrangement of the solar panel / module is to assume that the traffic noise is not optimally far over the noise barrier.

In DE 196 02 779 A1 a photovoltaic sound barrier is shown. It consists of modular elements which can be joined together in a modular manner and which have lugs formed on the sound-receiving side, which lugs serve for receiving photovoltaic solar modules to be placed thereon. This should create sound-absorbing chambers. The arrangement involves a not inconsiderable manufacturing effort and the size of the solar panels is limited because of a mutually possible shading.

The solution of DE 39 40 023 A1 proposes a noise barrier equipped with photovoltaic solar generators or noise control elements. Behind the upper edge of the noise barrier cantilevers are arranged, which have a tiltable frame for a solar module can be placed thereon. Again, it is true that the effectiveness of the noise barrier is limited if the traffic noise is no longer - with mechanically damaged or missing solar modules - can be derived obliquely upwards over the wall.

Further examples for avoiding / reducing traffic noise, while at the same time generating electrical energy, can be found in running transport projects, such as a multifunctional noise protection system on the BAB 2 near Gleisdorf, a photovoltaic noise protection wall with 500 kWp in Freising or a photovoltaic system noise protection wall on a bridge structure the BAB 31 at ends. - The latter three examples are very production and cost intensive, so that a solution must be sought, which overcomes the disadvantages of the prior art found.

It is therefore an object of the invention to provide a one-piece or multi-piece plate-shaped reinforced concrete wall in the smallest possible thickness, which is stable in itself with supports arranged behind it in conjunction, resting on a base plate of a concrete foundation and is provided without further sound-absorbing coatings or shapes , wherein on its side facing the noise emission a triangular cross-section designed structure is attached, which carries in several rows launched solar modules for photovoltaic energy in such a way that an angle of the solar modules for solar radiation of about 35 ° to 45 ° can be reached and their Area results in a slope beginning far in front of the noise barrier up to the upper end of the noise barrier, whereby the effects of a noise source far above behind the noise barrier located z. For example, residential buildings, etc. are distracted.

The object of the invention is achieved as follows, reference being made to the basic inventive idea of claim 1.

The further embodiment of the invention is set forth in claims 2 to 5.

To explain the invention further references are required.

The noise barrier itself consists of delicate reinforced concrete wall panels, which are superimposed in several rows one above the other in a defined height while maintaining their firm hold by a system and attachment to supports. The bottom reinforced concrete wall plate has connection with a base plate, which in turn rests together with a respective support on a block foundation.

The smooth on both sides of the noise barrier closes a consisting of upper straps, lower straps, stems and struts existing structure, in particular of natural materials such. For example, there is softwood, with a respective post and lower flange of the torsion-resistant structure resting on the base plate in front of the noise protection wall. The post assumes a firm connection to the reinforced concrete wall panels of the noise barrier. The structure consisting of individual binders for the photovoltaic modules placed thereon is superimposed with the lower chords of the binder relative to the base plate on a second block foundation located further upstream of the noise protection wall, where it corresponds in cross-section, a right-angled equal or non-equilateral triangle.

It is envisaged that the upper flange of the truss of the structure from the upstream second block foundation at an angle of 35 ° to 45 ° from the horizontal starting, so that the structure with its top, which corresponds to a hypotenuse of a right triangle, in each case to the Peak of the noise barrier runs. The individual binders are joined together by purlins, the latter forming the supports for the photovoltaic modules.

The oblique, almost closed surface of the applied photovoltaic modules results in a deflection of the noise level of a noise source well beyond the noise barrier.

The invention will be explained in more detail with reference to an embodiment. It gets up 1 resorted.

A noise barrier 1 , consists of several reinforced concrete wall panels stacked horizontally with their narrow sides 8th in a slender design, with its front and back smooth surfaces. The noise barrier 1 resting on a base plate 9 that are on a block foundation 14 supports, with supports 10 , behind the noise barrier 1 located, the latter stabilize. A second block foundation 11 , in front of the block foundation 14 placed, serves next to the base plate 9 as a support of a lower flange 7 for each individual binder of the entire structure, whereby the binders by purlins laid on them 3 are held in a vertical position while the purlins 3 Support and attachment points for photovoltaic modules 2 form.

The upper strap 4 each binder has in particular an angle of 45 ° to the horizontal, so that virtually a closed surface of the structure at its top by the photovoltaic modules 2 up to the upper end of the noise barrier 1 arises. As a result, the noise from the direction of a noise emitting source z. For example, from a highway, a track system far beyond the noise barrier 1 distracted so that adjacent urban settlement areas are not affected.

The structure with the photovoltaic modules placed on top 2 stands over the posts 13 with the noise barrier 1 at the front in firm connection.

• – die Lärmschutzwand kann aus feingliedrigen und damit leichten Stahlbetonplatten errichtet werden
• – die Lärmschutzwand weist an Vorder- und Rückseite eine glatte Oberfläche ohne schallschluckende Elemente, Kammern etc. auf
• – in Verbindung mit Photovoltaikmodulen, die separat zur Lärmschutzwand auf einem Tragwerk vorgelagert sind und sie statisch nicht belasten, wird ein wirtschaftlich günstiger Zusatzvorteil erreicht.

The advantages of the invention can be summarized in:

• - The noise barrier can be constructed of slender and thus lightweight reinforced concrete slabs
• - The noise barrier has a smooth surface on the front and back without sound-absorbing elements, chambers, etc.
• - In conjunction with photovoltaic modules, which are separately upstream of the noise protection wall on a supporting structure and do not burden them statically, an economically advantageous additional advantage is achieved.
