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 and a method for mounting 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 a 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 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 moisture or dirt into the gap or spaces between the cladding elements. Additionally, the fastening profiles are anchored to the wall 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.
Subsequently published specification DE 10 2018 106 155 A1 of the applicant 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 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.
The cladding system according to the invention for a wall having the features of claim 1 has the advantage that the handling or the mounting on a wall is very easy. In particular, the cladding system according to the invention allows the mounting of the cladding system on a wall by home handymen, for example, without special knowledge of the material processing of the cladding elements and/or special tools being necessary.
The invention is based on the idea that the cladding elements are formed to the required shape which interacts with the fastening profiles at least partially by direct forming on the fastening profiles, or that the corresponding, required shaping of the cladding elements in the fastening area on the fastening profiles is ensured at the same time when the cladding elements are mounted on a wall. To this end, the cladding system according to the invention has a fastening profile for the simultaneous fastening of two cladding elements on their longitudinal or transverse sides, the fastening profile having a reception section for each of the two cladding elements, the reception section interacting with a fastening section, which is bent in relation to a base surface section of the cladding element, on the cladding element. A particularly important aspect of the invention is the arrangement of the fastening sections or of the two reception sections for the fastening sections of the cladding elements in the fastening profile in such a manner that a first fastening section of the cladding element extends at least essentially parallel to a base surface section of the cladding element and a second fastening section is disposed on the cladding element at an inclined angle, preferably between 30 degrees and 60 degrees, particularly preferably approximately 45 degrees, in relation to the base surface section. Additionally, the plane of a lateral wall surface of the second reception section assigned to the second fastening section is disposed outside the cross section of the cladding element on the fastening profile on the side which faces the reception section while the cladding element is disposed in the first reception section of the fastening profile.
Such a realization in particular 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 by its fastening section when a (first) cladding element is mounted on the wall via the first fastening section by means of the fastening profile, wherein the second cladding element is in a state in which the fastening section is still flat or is not yet formed. The 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.
Advantageous embodiments of the cladding system according to the invention for a wall are disclosed in the dependent claims.
The two reception sections on the fastening profile preferably have reception openings for the fastening sections which are disposed on sides of the fastening profile which face one another so that gaps in the area of the fastening profile between the individual cladding elements are as small as possible. What is more, such an arrangement also causes mounted cladding elements to 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.
A preferred constructive embodiment of the fastening profile provides that the first reception section on the fastening profile has an extension on the side which faces away from the fastening surface of the fastening profile, the base surface section of the cladding element contacting the extension on the side facing the first fastening section. In addition to the reception of the first 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.
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.
An embodiment of the latter proposal provides that at least one fastening screw for anchoring the fastening profile to the wall can be positioned in the area of the fastening surface and in alignment with the insertion slot, a partial length of the first fastening section disposed inside the reception section being larger than the distance between the fastening screw and a surface of a lateral wall of the cladding element facing the fastening screw and extending perpendicular to the reception opening. Such a geometric dimensioning has the particular advantage that the one cladding element received by the fastening profile is secured inside the reception section by the fastening screw when the fastening profile is mounted on the wall.
Either for optical reasons or for avoiding corrosion, another embodiment can moreover provide that the insertion slot is at least partially covered inside the cross section of the fastening profile by means of a strip-shaped cover profile.
In particular in order to realize a mounting as easy as possible of the cover profile inside the fastening profile, an embodiment of the design of the latter proposal provides that the cover profile has an L-shaped cross section and can be anchored into a reception slot 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.
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 or arrangement of the (fastening) screws or screw openings, which are provided for the anchoring of the fastening profile to the wall, on the fastening profile during the mounting on site.
Another preferred embodiment of the fastening profile provides that said fastening profile has a section for receiving a fastening section of the cladding element, the section being used as a folding aid for the fastening section on the cladding element. It is therefore possible to insert the cladding element into the section of the fastening profile in order to fold the (first) fastening section on the cladding element and the user can thus apply the forces required for the folding of the fastening section via the base surface section in a particularly simple manner.
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 the second reception section is disposed above the first reception section on the fastening profile in relation to a bottom of the wall. 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.
To limit the weight of the individual cladding elements, in particular for reasons of handling or weight, an embodiment provides that at least three fastening profiles disposed parallel to one another and two cladding elements disposed between the fastening profiles are provided. Walls whose height is higher than the corresponding height of an individual cladding element can thus be provided with corresponding cladding elements.
Furthermore, the invention comprises a method for mounting a cladding system according to the invention as described above, the method according to the invention comprising at least the following steps: Firstly, a fastening profile is anchored to a wall. The second fastening section of a cladding element is then inserted into the reception section of the fastening profile in a state in which the second fastening section is not deformed to the base surface section of the cladding element. The base surface section is then bent to the second fastening section until the cladding element can be fixed to the wall by means of another fastening profile which is connected via the first fastening section of the cladding element. Finally, the other fastening profile is fixed to the wall.
An advantageous embodiment of the method according to the invention as described above provides that the first fastening sections are manually formed from the recently formed plane cladding elements and inserted into the first reception sections of the fastening elements before the second fastening sections are formed on the fastening profiles. For this purpose, as described above, the additional sections provided in the fastening profiles in particular can be used as a folding aid.
An alternative method for mounting a cladding system according to the invention on a wall provides that the fastening sections are formed on a cladding element before the connection with the fastening profile. Such a method is particularly advantageous if relatively large or heavy cladding elements are provided which are relatively difficult to handle (on the wall). In this case, the alternative method provides that at least the following steps are performed: Firstly, a first and second fastening section are formed on a plane cladding element. A fastening profile is then anchored to the wall and a formed first or second fastening section is inserted into an assigned reception section of the fastening profile. Alternatively, a formed first or second fastening section is inserted into an assigned reception section of a fastening profile in a state in which the fastening profile is not yet fastened to the wall and the fastening profile is subsequently fastened to the wall. As the next step, the other formed fastening section is inserted into another fastening profile in a state in which the additional fastening profile is not yet connected to the wall. Finally, the other fastening profile is fixed to the wall.
