    The invention relates to a wall element for a noise protection wall, the wall element having a body and having at least one outside, the body having a support towards the at least one outside, at least one solar module being arranged on the support and being connected to the body, wherein the solar module is inclined with respect to a vertical in the direction of an upper side of the wall element, the body having on the at least one outer side at least one sound absorption surface that can be reached directly for incoming sound.
    A connection of noise protection components with photovoltaic modules and the associated general advantages have been known for a long time. A basic problem with this connection is that the surface of photovoltaic modules is generally sound-reflecting and therefore diametrically opposed to the desired properties of a noise protection component.
    A workaround for this problem is, for example, in the
    DE 93 18 768 U1 discloses. There, a photovoltaic laminate is arranged parallel to the extension plane of a noise protection component on the rear side. The front of the noise protection component thus remains unused for energy generation. Apart from this, if the noise protection component is arranged vertically, the optimal efficiency of the photovoltaic module cannot be achieved due to the fact that it is also arranged vertically.
    In another context, namely not for wall elements, but for existing soundproof walls, a solution to these problems is known from DE 20 2011 004 458 U1. This shows a soundproofing system in which a plurality of solar modules are arranged in an inclined arrangement on a soundproofing wall. The solar modules are connected to a support structure independently of the specially provided soundproofing segments, so that the solar modules and soundproofing segments can be replaced independently of one another. However, this has the disadvantage that the overall effort for installing the soundproof wall is significantly higher than with a conventional soundproof wall (without solar modules).
    To eliminate this disadvantage is already from the / 17
    KR 10 2018 0022124 A1 discloses a combined wall element that combines both functions, namely sound absorption and photovoltaics. The effort for the construction of a corresponding noise barrier is therefore hardly higher than with a conventional noise barrier and, moreover, essentially only involves the production of the electrical connections. A disadvantage of this wall element, however, is its complex structure and the associated large number of required components, and ultimately the resulting high manufacturing costs.
    DE 196 02 779 A1 shows a wall element of the type mentioned at the beginning, which at least partially avoids or alleviates the disadvantages mentioned above. The wall elements are formed by prefabricated components, the solar modules being fastened on noses formed integrally thereon. The surface of the prefabricated components that can be directly reached for horizontally arriving sound, i.e. H. that is not covered by a solar module is small compared to the entire face.
    The two last-mentioned known solutions attempt to solve the basic problem mentioned at the outset of the sound absorption properties of the individual wall elements, which are deteriorated by the use of solar modules, in that the sound is to be diverted into chambers behind the solar modules in order to absorb them there. In practice, however, such a diversion does not work to a sufficient extent to meet the increasingly restrictive requirements for the sound absorption level of noise barriers.
    It is an object of the invention to eliminate or at least reduce this disadvantage.
    The invention provides a wall element of the type mentioned at the outset, the sound absorption surface being inclined at least in sections with respect to the vertical and / or with respect to a longitudinal direction of the wall element, the surface area of the sound absorption surface being at least as large as the surface area of a visible surface of the wall element , The sound absorption surface is that part of the surface of the wall element on the outside thereof which is outside of / 17
    Surface of the at least one solar module that is directly accessible for incoming sound, d. H. without any previous reflection or redirection of the sound. Parts of the surface of the wall element covered by a solar module for incoming sound are therefore not to be attributed to the sound absorption surface. The visible area of the wall element corresponds to the area of an outline of the wall element in a side view of the outside. More specifically, the outside view surface is meant, i. H. in the direction of view normal to the vertical and normal to a longitudinal extent of the wall element on the at least one outside. Due to the inclination of the sound absorption surface, at least in sections, its surface area is larger than the surface area of its own visible surface. The relative difference between the two areas depends on the angle of inclination. At an inclination angle of 45 °, the ratio of face to surface is approximately 1: 1.4 (1 to square root of 2). It follows that if approximately 71% of the visible surface is formed by 45 ° inclined sound absorption surfaces and solar modules occupy the remaining 29% of the visible surface, the surface area of the sound absorption surface is at least as large as the surface area of the visible surface of the wall element. The outside can be a side facing the sound. The vertical is the axis that extends between the bottom and the top of the wall element. The designation as "vertical is not restrictive for the use of the wall element, which can therefore also be used for inclined noise barriers without leaving the subject matter of claim 1. In the case of a typically vertically erected noise barrier made of the wall elements described here, the vertical corresponds to the absolute vertical of the noise barrier. The vertical is normal to a longitudinal direction of the wall element, for example. The view surface as defined above then corresponds to the surface of a projection of the wall element in a plane spanned by the vertical and the longitudinal direction.
    The incoming sound (sound immission) reaches the sound absorption surface directly, but not necessarily horizontally (normal to the vertical). Since the majority of the sound immission comes from a relatively small area of / 17
    If the spatial angle is expected, it is advantageous if the surface area of those sections of the sound absorption surface which can be reached directly for sound arriving from a noise immission area is (overall) at least as large as the area content of a visible surface of the wall element, the noise immission area being an angular range between a normal to the vertical and an inclination set at 70 ° from this normal towards a bottom of the wall element. Optionally, the above condition for the surface area of the sections of the sound absorption surface can already occur in the case of a noise immission area with an angular range between a normal to the vertical (hereinafter referred to as normal for short) and a 60 ° from this normal in the direction of an underside of the wall element inclination must be fulfilled, or with an angular range between 0 ° and 50 °, or with an angular range between 0 ° and 40 °, or with an angular range between 0 ° and 30 °, or with an angular range between 0 ° and 20 °, or with an angular range between 0 ° and 10 °.
    The area of the sound absorption surface can correspond to approximately 1.2 times or more than the area of a visible surface of the wall element. The larger sound absorption surface further improves the sound absorption properties of the wall element and, given the absorber material, e.g. of the body, a better degree of sound absorption can be achieved (i.e. more sound or sound energy is absorbed). Optionally, the area of those sections of the sound absorption surface that can be reached directly for sound arriving from the noise immission area can correspond (in total) to at least 1.2 times the area of a visible surface of the wall element.
    Furthermore, the body can have an upper bearing surface and a lower bearing surface for stacking a plurality of wall elements in a stacking direction, the bearing surfaces being arranged at least partially essentially normal to the vertical. The bearing surfaces allow an adjacent arrangement of several wall elements in the vertical direction, so that a noise barrier of different heights can be formed depending on the number of rows of wall elements.
    / 17th
    According to a further exemplary embodiment, the sound absorption surface can be at least predominantly covered by the solar module in a direction of view normal to the solar module. Assuming a normal incidence of light on the solar module (corresponds to the optimal efficiency), the sound absorption surface then lies at least for the most part in the shadow of the solar module. This arrangement of the solar module and the sound absorption surface enables a particularly high utilization of the incident solar energy. It is irrelevant whether the sound absorption surface lies through a solar module of the same wall element or an adjacent or adjacent wall element arranged above it along the vertical.
    Optionally, the sound absorption surface in a noise barrier wall comprising the wall element can be arranged completely within a shadow line between an upper edge of a lower solar module and a lower edge of an upper solar module. In this way it can be avoided that the profile of the sound absorption surface affects the efficiency of the solar modules by shadows.
    In this regard, according to a special
    Embodiment of the body on the at least one outside outside the solar module have at least one elevation to enlarge the sound absorption surface, wherein an outer edge of the elevation touches the shadow line or lies within the shadow line. With such an elevation, the space within the shadow line can be optimally used to enlarge the sound absorption surface without impairing the efficiency of a solar module (the same or an adjacent wall element) which may be arranged underneath.
    As an alternative or in addition, the distance between solar modules that are adjacent in the direction of the vertical can be selected in such a way that a noise protection wall comprising the wall element is arranged such that the shadow line between these solar modules is arranged essentially normally on the front of at least one solar module. With this arrangement, assuming that light falls on the solar module normally (corresponds to the optimum efficiency), the upper solar module does not cast a shadow on the lower solar module.
    6.17
    Optimal use of the available photovoltaic area can thus be achieved.
    Furthermore, a side view of the outside of the
    Distance between adjacent solar modules in the vertical direction may be greater than or equal to the distance between an upper edge and a lower edge of a solar module. In other words, with this configuration, the solar modules take up 50% or less of the visible area. This avoids very shallow angles of inclination (less than 30 °) of the sound absorption surface and the associated very pointed edges (less than 60 ° included angles), which could have a restrictive effect on the material that can be used for the body without endangering its structural integrity.
    The body can, for example, essentially consist of a sound-absorbing material. The sound-absorbing material can be suitable for forming a support structure for the solar module. A material with a sound absorption level of e.g. understood at least 4 dB. The sound absorbing material can be wood concrete, for example. In the context of the present disclosure, the body can also consist of another sound-absorbing material, such as perforated concrete.
    The invention is explained in more detail below on the basis of particularly preferred exemplary embodiments, to which, however, it should not be restricted, and with reference to the drawings. The drawings show in detail:
    Figure 1 is a perspective view of a first embodiment of the wall element in question.
    2 schematically shows a vertical section of the first embodiment of the wall element in question;
    3 schematically shows a vertical section of a noise protection wall with wall elements arranged on both sides;
    4 shows a perspective view of a wall module with wall elements arranged on both sides; and
    Fig. 5 is a perspective view of a noise barrier with wall elements arranged on both sides.
    1 and 2 show a wall element 1 for a / 17
    Noise barrier. The wall element 1 has a body 2 made of wood concrete and a solar module 3. The wall element 1 has an outer side 4 (also front side). The body 2 has two elevations 5, 6 or projections on the outside 4. The first elevation 5 forms a support 7 toward the outside 4, on which the solar module 3 is arranged and connected to the body 2. The solar module 3 is inclined with respect to a vertical 8 in the direction of an upper side 9 of the wall element 1.
    In addition, the body 2 has on the outside 4 a sound absorption surface 10 which can be directly reached from a noise immission area corresponding to an angular range 34 of normal (ie parallel to the normal 32) or up to an inclination 33 of 45 ° below the normal 32 to the vertical 8 on. The second elevation 6 is arranged outside the solar module 3, more precisely to the side or adjacent to the solar module 3, and serves to enlarge the sound absorption surface 10, an outer edge 11 of the elevation 6 touching a shadow line 12 below the solar module 3, so that the elevation 6 lies within the shadow line comes to rest. The sound absorption surface 10 is completely covered by the solar module 3 in a viewing direction normal to the solar module 3.
    Due to the geometry of the second elevation 6 (with a triangular profile), the sound absorption surface 10 is essentially divided into three sections 13, 14 and 15, which are related to FIG
    Vertical 8 of the wall element 1 are inclined or normal. The surface area of the sound absorption surface 10 is larger than the surface area of a visible surface of the wall element 1, e.g. by approximately 1.2 times.
    The body 2 has an upper bearing surface 16 and a lower bearing surface 17 for stacking a plurality of wall elements 1 in a stacking direction (see FIG. 3). The bearing surfaces 16, 17 are arranged for the most part essentially normal to the vertical 8.
    In the possible embodiment described, the sound absorption surface 10 has, in addition to the three inclined or horizontal sections 13, 14 and 15, one parallel to the
    Fourth section 18 arranged vertically between the two / 17th
    Elevations 5, 6, which should avoid the possibly problematic acute angle between the two elevations 5, 6 in production. For the same reason, the tip (outer edge) of the first elevation 5 is chamfered.
    3 shows a noise barrier 19 in which a plurality of wall elements 22 are arranged vertically one above the other on both sides 20, 21. The individual wall elements 22 are constructed from two modules 23, 24, the individual modules 23, 24 each according to a wall element 1 according to the embodiment
    FIGS. 1 and 2 correspond, and the two modules 23, 24 have a common, continuous body 25, so that two modules 23, 24 together form a wall element 22 (with two solar modules accordingly). The noise barrier 19 has a supporting core 26, e.g. made of reinforced concrete or a lightweight structure between steel posts (post spacing e.g. 165, 200 or 500 cm), as well as a base area 27 made of concrete.
    The distance between the adjacent solar modules 3 in the direction of the vertical of the noise barrier 19 is selected such that the shadow line 12 between these solar modules 3 is essentially normal to the outside of the solar modules 3 arranged in parallel in this example. In a side view of the outside 4 (not shown, but recognizable from the profile shown), the distance between solar modules 3 adjacent in the vertical direction (for example 14 cm) is greater than or equal to the distance between an upper edge 28 and a lower edge 29 of a solar module 3 (e.g. 11 cm). The sound absorption surfaces 10 of the wall elements 22 are each arranged completely within a shadow line 12 between an upper edge 28 of a lower solar module 3 and a lower edge 29 of an upper solar module 3.
    The wall elements 22 (with a module height of for example 25 cm and a corresponding element height of for example 50 cm) are stacked so that the bearing surfaces 16, 17 are adjacent
    Touch wall elements 22. The width of the solar modules 3 is 16.5 cm, for example. The individual wall elements 22 are connected to the supporting core 26, for example glued or screwed on.
    / 17th
    4 schematically shows a section of the noise barrier 19 corresponding to a wall module. The wall module comprises a section of the core 26. A wall element 22 with a continuous body 25 is arranged on both sides 20, 21 of the core section. Each band element has two modules 23, 24, each of which is equipped with a solar module 3. The wall module shown here has, for example, a dimension along the vertical 8 (height) of approximately 50 cm. Each module 23, 24 or each module row is therefore approx. 25 cm high. The solar modules 3 are about 16.5 cm wide. Alternatively, it can be provided that a wall module of this height has three rows of modules, the solar modules having a width of approximately 12.5 cm. However, it is also conceivable to provide wall modules with only one row of modules, e.g. with a height of 25 cm.
    FIG. 5 shows a diagrammatic view of a noise protection wall 19 with wall elements arranged on both sides, comparable to FIG. 3. The noise protection wall 19 is divided in the longitudinal direction into sections which are each delimited by steel studs 30, are supported and are anchored in the floor. The noise barrier wall sections 31 which are adjacent in the longitudinal direction are indicated by dashed lines in FIG. 5 in order to illustrate the continuation of the noise barrier wall by repeating or lining up a plurality of noise barrier wall sections in a row.
