The invention relates to a cladding system for a wall. Furthermore, the invention relates to an arrangement of a cladding system according to the invention on a wall.
Various cladding systems for walls are known from the state of the art. In particular, they are used for the optical design of the wall and/or for a protection of a building wall against weather conditions or the like. The known cladding systems are normally composed of fastening elements in the form of oblong fastening profiles which can be mounted on the wall and which interact with cladding elements. The cladding elements are plate-shaped and have fastening sections, in particular on the longitudinal or transverse sides, which interact with the fastening profiles in order to connect the cladding elements to the fastening profiles. In addition to the intended optical properties of the cladding elements, a number of requirements of such a cladding system are known to guarantee the intended functionality or the protection of the wall over a long period of time. In particular, gaps or joints between the individual cladding elements are to be as small as possible. This serves not only visual reasons, but also to minimize the ingress of rain or dirt into the joints or spaces between the cladding elements. Additionally, the fastening profiles are anchored to the wall or on a substructure via screw connections, for example. Said screw connections are to be covered or disposed so as to be visually imperceptible, if applicable, by a corresponding geometric design of the cladding elements.
Specification DE 10 2018 106 155 A1 of the applicant already discloses a cladding system for a wall which is realized in a particularly advantageous manner with respect to the optical and functional design. In this realization, the individual cladding elements are anchored to the wall in the area of the longitudinal sides and of the transverse sides by means of fastening profiles. Furthermore, the known cladding system or the cladding elements are realized as sandwich components which have a core area and cover layers which are made of aluminum and cover the core area on both sides. This material has become known by the trade name ALUCOBOND® of the applicant and has already proven its worth in the worldwide use for such cladding systems. To fasten such a cladding element to a fastening profile, the specification mentioned above also discloses the creation of folding areas via groove-shaped milled slots on the cladding elements, sections used for the fastening to the fastening profile being manually bendable via the folding areas.
From WO 2020/084143 A1 of the applicant, a cladding system having the features of the preamble claim 1 is known. Said cladding system is characterized in that it allows an easy mounting on a wall. To this end, two reception sections for fastening sections on the cladding elements are provided on a fastening profile. An essential aspect is that a cladding element which can be anchored to the fastening profile has two fastening sections which are folded in a different manner, wherein the one fastening section is bent in the shape of a U, whereas the other fastening section is bent in the shape of a V or disposed at an inclined angle. The section which extends parallel to the plane of the cladding element on the fastening section bent in the shape of a U of the cladding element makes it necessary for the insertion slot realized between the two reception sections on the fastening profile to have a certain minimum width so that the fastening section can be inserted into the insertion slot. However, for optical reasons in particular, there is often a desire to design the insertion slot as narrow as possible. For this reason, it is also known from the specification mentioned above that the area of the insertion slot and of fastening screws for anchoring the fastening profile to the wall are covered inside the fastening profile by means of a strip-shaped cover element. However, the mounting of said cover element causes additional work and increases the costs. Furthermore, the U-shaped folding of the fastening section on the cladding element requires an additional work step compared to a simple, V-shaped folding.
The cladding system according to the invention for a wall having the features disclosed herein has the advantage that it allows a minimization of the insertion slot realized between reception sections for the cladding elements while simplifying the mounting process of the cladding system. Furthermore, the cladding system according to the invention allows an optimized or uniform deformation of the cladding elements when wind forces occur, for example, because the cladding elements have the same shape or same cross section in the area of their fastening. The manufacturing process of the cladding elements is also simplified compared to the state of the art, because the number of milling processes required to form grooves for folding is reduced and the same milling cutter can always be used.
The invention is based on the idea that the cladding elements are directly folded to the fastening profile at their fastening sections, namely in such a manner that the insertion slot can be minimized.
Thus, starting from the state of the art according to WO 2020/084143 A1 mentioned above, an essential aspect of the invention is that the fastening profile is realized in such a manner that the second reception section, like the first reception section, is bent at an inclined angle—and thus not in the shape of a U—wherein the inclined angle is preferably disposed between 30 degrees and 60 degrees, particularly preferably approximately 45 degrees, in relation to the fastening surface or to the base surface section of the cladding element, wherein a plane aligned with a lateral surface of the reception section assigned in the first or second reception section extends outside the cross section of a cladding element disposed in the other reception section, and wherein the two reception sections on the fastening profile have reception openings for the fastening sections of the cladding element which are disposed on sides which face one another on the fastening profile.
What is more, the latter feature also has the effect that mounted cladding elements block one another in a release direction, if applicable, and thus avoiding an unintended release of a cladding element from the fastening profile. This is of particular importance in connection with external forces which may occur as a result of wind forces or the like.
Furthermore, a realization defined of the cladding system disclosed herein allows a mounting of a cladding element when the fastening profile is already fastened to or anchored to the wall. In this process, another (second) cladding element can be inserted into the assigned reception opening of the fastening profile via its fastening section when a (first) cladding element is mounted on the wall via the first fastening section by means of the fastening profile, namely in a state in which the fastening section is still flat or is not yet formed. The V-shaped folding or bending of the fastening section on the cladding element is almost necessarily realized in a subsequent mounting step, namely in the manner which is required to be able to fasten the pre-mounted cladding element to the wall or to form a plane wall surface.
Advantageous embodiments of the cladding system according to the invention for a wall are disclosed in the dependent claims.
Particularly preferably, the two inclined angles of the reception sections on the fastening profile have the same size. In particular, this means that it is not necessary to pay attention to a specific mounting position of the fastening profile on the wall, because said fastening profile can be mounted on a wall at two positions which are offset by 180 degrees to one another.
A preferred constructive embodiment of the fastening profile also provides that the reception sections on the fastening profile each have an extension comprising a support surface on the side which faces away from the fastening surface of the fastening profile, the base surface section of the cladding element contacting the support surface on the side facing the first fastening section via a back parallel to the fastening surface, the two support surfaces being disposed parallel to and at the same distance from the base surface section of the fastening profile. In addition to the reception of the fastening section of the cladding element in the corresponding reception section of the fastening profile, such a realization also causes an additional form-fitting contact of the cladding element at the fastening profile for the exact positioning of the cladding element. In particular, this forces the cladding elements to form a plane overall surface or wall façade, even if, for example, the strip-shaped fastening sections on the cladding elements have different widths or narrow dimensions and thus project to different extents into the reception sections of the fastening profile.
To minimize the cross section or the required material of the fastening profile, the two reception sections are advantageously disposed at opposite edges of the fastening profile in relation to a transverse direction which extends perpendicular to the longitudinal direction of the fastening profile.
Preferably, the fastening or mounting of the individual cladding elements takes place by realizing an insertion slot, which serves for inserting the cladding elements into the reception sections, between the reception sections on the side of the fastening profile which faces away from the fastening surface, the insertion slot being continuous in the longitudinal direction of the fastening profile.
With respect to the mechanical strength and a relatively low weight, the cladding element is particularly advantageously realized as a sandwich component which has a core area and cover layers which are made of aluminum and cover the core area on both sides, wherein grooves are provided at edges and are realized in the area of a cover layer and of the core area of the cladding element. The grooves at the edges cause an intended weakening of the material of the cladding element in order to be able to fold the fastening sections, in particular manually and at the intended position from the plane of the cladding element. However, alternatively the cladding element can be made of a (single-layer) aluminum plate which has a thickness of approximately 1 mm to 3 mm.
In particular in order to improve the corrosion properties, it is intended that the fastening profile is made of aluminum and is realized as an extruded part. The fact that the fastening profile is made of aluminum moreover also allows the particularly simple realization of the (fastening) screws or screw openings, which are provided for the anchoring of the fastening profile to the wall, on the fastening profile with little effort during the mounting on site.
Furthermore, the invention comprises an arrangement of an above-described cladding system according to the invention on a wall. The arrangement according to the invention is characterized in that, in relation to a bottom of the wall, the two reception sections extend perpendicular to the bottom of the wall on the fastening profile. Such an arrangement of the reception sections and therefore of the corresponding fastening sections of the cladding elements causes that an accumulation of water or dirt in the gaps between the cladding elements on the fastening profile is minimized, because the corresponding media or substances are transported towards the bottom by gravity. Alternatively, the fastening profiles can of course be fastened parallel to the bottom of the wall, forgoing the advantage mentioned above.
Further advantages, features and details of the invention are apparent from the following description of preferred exemplary embodiments and from the drawing.

The two reception sections 16, 18 each realize a reception opening 31, 32 for respective fastening section 60, 62, the two reception openings 31, 32 being disposed on sides facing one another on fastening profile 10 or towards symmetry plane 15.
Fastening profile 10 has a continuous insertion slot 34 between both reception sections 16, 18, the insertion slot 34 extending in the longitudinal direction of fastening profile 10 and serving for inserting respective fastening section 60, 62 of respective cladding element 50 into corresponding reception section 16, 18.
Additionally, the cross section of fastening profile 10 has one channel 35 near both of the two reception sections 16, 18, respectively, channel 35 having an additional longitudinal slot 37 and extending in the longitudinal direction. Channel 35 is used for the fixation of cladding elements 50 by means of additional fastening elements (not shown) in an arrangement on wall 1 in which fastening sections 60, 62 extend in a vertical direction in relation to wall 1.
