Description

[0001] Facade system and adapter device of a corresponding facade system

[0002] State of the art

[0003] The invention particularly relates to a facade system with a holding device having recesses and with facade elements, wherein the recesses are provided to receive extensions of the facade elements in order to fasten the facade elements to the holding device.

[0004] A corresponding facade system is already known from EP 3 730 718 A1. The facade system described therein, and in particular the retaining device with its retaining elements described therein, are to be considered in their entirety as part of the disclosure of the present description.

[0005] The object of the invention is, in particular, to increase the flexibility of a generic facade system. This object is achieved by the features of patent claim 1, while advantageous embodiments and further developments of the invention can be found in the subsidiary and dependent claims.

[0006] Advantages of the invention

[0007] The invention is based on a facade system with a holding device which has at least one recess, and with at least one first type of facade element, wherein the recess is designed to receive at least one extension of the facade element of the first type in order to fasten the facade element of the first type to the holding device.

[0008] It is proposed that the facade device comprise at least one adapter device which is designed to be at least partially inserted into the recess in order to thereby fasten at least a second type of facade element, in particular a solar facade element, to the holding device. In this context, a “solar facade element” is to be understood as an element which is intended to convert solar energy into another form of energy, such as in particular electrical energy and / or thermal energy, for example by heating an energy source. The adapter device is preferably designed to be mounted on a facade element, in particular in order to achieve mounting compatibility. In this context, “designed for this purpose” is to be understood as being specifically shaped and provided for this purpose.

[0009] With a corresponding design, advantageous installation compatibility can be achieved, particularly with different types of facade elements, a particularly high degree of flexibility of the facade system can be achieved and, in particular, an advantageous use of solar energy can be enabled.

[0010] In addition to a “solar façade element” of the second type of façade element, other façade elements that appear appropriate to the expert are also conceivable, such as a façade foundation element, a window element, etc.

[0011] In a further embodiment of the invention, it is proposed that the adapter device has at least a first type of adapter element and at least a second type of adapter element, wherein the adapter elements are intended to be coupled to different regions of two facade elements of the second type during assembly. By “different regions” it should be understood that the adapter element of the first type is intended to be coupled in a first region of a first facade element of the second type, such as preferably in an upper region of the facade element of the second type, and the adapter element of the second type is intended to be coupled in a second region of a second facade element of the second type, which differs from the first region, such as preferably in a lower region of the facade element of the second type. The two facade elements of the second type are preferably of identical construction.

[0012] By means of an appropriate design, an advantageously simple and secure fastening of the facade elements of the second type can be achieved.

[0013] This is further advantageously supported by the fact that the adapter elements are designed to be coupled together during assembly. The retaining interfaces of the adapter elements can advantageously be adapted to each other and to the retaining device independently of the facade element of the second type.

[0014] If the adapter elements are designed to at least partially engage with each other in an assembled state, advantageous form-fitting and possibly additional particularly advantageous frictional connections can be achieved.

[0015] In a further embodiment, it is proposed that the adapter device comprise at least a first type of adapter element, which comprises a vertical hook extension intended to be inserted into a vertical recess region of the recess of the holding device during assembly, which in turn can assist in achieving an advantageous positive fit. In this context, a "vertical hook extension" is understood to mean an extension that, together with an adjacent part of the adapter element, forms a hook, and whose main extension, viewed in an assembled state of the facade system, has at least one main component in the vertical direction.It is further proposed that the vertical hook extension of the adapter element of the first type be formed by a profile with opposing side cheeks, such as preferably a U-profile or a V-profile, whereby particularly advantageous rigidity and, in particular, a particularly advantageous receiving area for a further fastening element, in particular for a part of a further adapter element, can be achieved. Furthermore, an adapter element with a small wall thickness can be used particularly advantageously, which can be formed easily and cost-effectively.

[0016] Advantageously, the vertical hook extension of the adapter element of the first type, viewed in the assembled state of the facade system, has a horizontal extension in the facade normal direction of less than 14 mm and preferably less than 10 mm and / or advantageously greater than 2 mm and particularly preferably greater than 3 mm and / or advantageously a vertical extension of less than 35 mm and preferably less than 30 mm and / or greater than 10 mm and preferably greater than 20 mm, whereby particularly advantageously dimensioned, manageable facade elements, in particular solar facade elements, can be installed easily and safely with little material expenditure.

[0017] Furthermore, an advantageous assembly and fastening interface can be achieved if the adapter element of the second type has a vertical hook extension which is intended to be inserted during assembly between the opposite side cheeks of the profile of the vertical hook extension of the adapter element of the first type, so that, viewed in the assembled state of the facade system, the vertical hook extension of the adapter element of the second type is arranged between the side cheeks of the profile of the vertical hook extension of the adapter element of the first type.

[0018] If the vertical hook extension of the adapter element of the second type has a horizontal extension, an advantageous form fit and, in particular, also a force fit can be achieved in a structurally simple manner, namely between the vertical hook extension of the adapter element of the second type and the vertical hook extension of the adapter element of the first type.

[0019] A corresponding horizontal extension can be formed at least partially by a bend in a cost-effective and structurally simple manner, although other possibilities that appear sensible to the person skilled in the art are also conceivable, such as by means of a plastic coating, etc. In this context, a "bend" should be understood in particular as a formation produced by a bending process.

[0020] In a further embodiment, it is proposed that the adapter device comprise at least one adapter element forming a floor or roof element for a facade element of the second type, whereby bearing forces in particular can be advantageously absorbed and the tightness of the facade system can be advantageously supported. In this context, a “floor element” is to be understood as an element which covers the facade element of the second type on an underside thereof, as viewed in the assembled state of the facade system. In this context, a “roof element” is to be understood as an element which covers the facade element of the second type on an upper side thereof, as viewed in the assembled state of the facade system.

[0021] The adapter device can be formed from various materials that appear appropriate to a person skilled in the art, such as metal and / or plastic, in particular fiber-reinforced plastic, and can also be produced by various manufacturing processes that appear appropriate to a person skilled in the art, such as a 3D printing process, a single-component or multi-component injection molding process, etc. However, the adapter device is particularly advantageously formed at least partially from a sheet metal part, as a result of which it can be manufactured particularly easily and cost-effectively even in large series, in particular if the sheet metal part is at least partially manufactured in an extrusion process.In a further embodiment of the invention, it is proposed that the holding device has at least one hollow profile which is divided into separate sections which are arranged offset from one another, whereby the facade elements of the first type and the facade elements of the second type can advantageously be arranged at least substantially in a common vertical plane in which a main facade surface lies.

[0022] It is particularly advantageous for the hollow profiles to be designed as multi-chamber hollow profiles, whereby the sections of the hollow profiles can be arranged offset from one another particularly easily, preferably with hollow profile connectors.

[0023] The facade system according to the invention is not intended to be limited to the application and embodiment described above. In particular, the facade system according to the invention may comprise a number of individual elements, components, and units that differs from the number stated herein to fulfill a functionality described herein.

[0035] Description of the embodiment

[0036] Fig. 1 shows a facade system with a holding device 10. The holding device 10 comprises holding elements formed by elongated hollow profiles 52, 54. The hollow profiles 52, 54 are formed by extruded profiles produced using an extrusion process. The hollow profiles 52, 54 are multi-chamber hollow profiles and have two hollow chambers 56, 58 with an intermediate wall 60 (see Fig. 3). In principle, it would also be conceivable for the hollow profiles 52, 54 to have more than two hollow chambers.

[0037] The hollow profiles 52, 54 have recesses 12, 14, 98, 100. Furthermore, the facade system has a first type of facade element 16, 18, 74 (see Fig.

[0038] 1 to 4). The facade elements 16, 18, 74 are formed from essentially identical sheet metal panels. Figure 1 shows only three facade elements 16, 18, 74 of the first type; in principle, the facade system also comprises additional facade elements 16, 18, 74 of the first type.

[0039] The recesses 12, 14, 98, 100 are all designed identically, with the recess 12 being configured to receive extensions 20, 22 of the facade elements 16, 18 of the first type in order to fasten the facade elements 16, 18 of the first type to the holding device 10 (see Fig. 4). The extensions 20, 22 are integrally formed on the facade elements 16, 18.

[0040] The facade system further comprises adapter devices 24, 118, 120, which are designed to be partially inserted into the recesses 14, 98, 100 of the holding device 10 in order to thereby fasten a second type of facade element 26, 28, namely PV facade elements, to the holding device 10. Figure 1 shows only two of the facade elements 26, 28 of the second type; however, the facade system fundamentally comprises further facade elements 26, 28 of the second type.

[0041] The adapter device 24, 118, 120 has a first and a second type of adapter elements 30, 32, 82, 84, 90, 92, which are formed from sheet metal parts and manufactured by an extrusion process. The adapter elements 30, 32, 82, 84, 90, 92 are intended to be fastened to the facade elements 26, 28 of the second type and, in transitions between the facade elements 16, 18, 74 of the first type and the facade elements 26, 28 of the second type, to the facade elements 18, 74 of the first type (see Figs. 5 to 9). The adapter elements 30, 32 are fastened to the facade elements 26, 28 of the second type via detachable fastening means, namely screws (see Fig. 5). However, other fastening means that may be deemed appropriate by the expert are also conceivable, such as locking devices, etc.The adapter elements 30, 32, 82, 84, 90, 92 extend across the entire width of the facade elements 26, 28 of the second type and across the entire width of the facade elements 16, 18, 74 of the first type, thereby advantageously achieving a visually appealing and, in particular, tight facade system. When installed, the adapter elements 30, 32, 82, 84, 90, 92 are arranged concealed behind the facade elements 16, 18, 26, 28, 74, as viewed from above.

[0042] The adapter elements 30, 32 are intended to be coupled to different areas of the facade elements 26, 28 of the second type during assembly (cf. Fig. 1, 5 to 7). The adapter elements 30 of the first type are intended to be fastened to an upper area of ​​the facade elements 28 of the second type, while the adapter elements 32 of the second type are intended to be fastened to a lower area of ​​the facade elements 26 of the second type (cf. Fig. 5). The facade elements 26, 28 of the second type are structurally identical. However, they could also differ in their design.

[0043] The facade system shown in Figure 1 thus has two types of facade elements 16, 18, 74, 26, 28, whereby facade systems with more than two types of facade elements 16, 18, 74, 26, 28 or even with only one type of facade elements 26, 28 are also conceivable, which are all fastened to the holding device 10, for example, with adapter devices 24, 118, 120 according to the invention.

[0044] The adapter elements 30, 32, 82, 84, 90, 92 are designed to be coupled together during assembly (see Figs. 5 to 9). The adapter elements 30, 32, 82, 84, 90, 92 have horizontal hook extensions 62, 64, 122, 124, 126, 128, which, when viewed in the assembled state of the facade system, have a main extension component in the horizontal direction and abut one another in the assembled state.

[0045] The adapter element 30, 90, 92 of the first type has a vertical hook extension 34, 94, 96, which is intended to be inserted into a vertical recess region 36, 102, 104 of the recess 14, 98, 100 of the holding device 10 during assembly. The vertical hook extension 34, 94, 96 of the adapter element 30, 90, 92 of the first type is formed by a profile with opposing side cheeks, namely a U-profile.

[0046] The adapter elements 30, 32, 82, 84, 90, 92 are further provided to partially engage with one another in an assembled state. For this purpose, the adapter element 32, 82, 84 of the second type has a vertical hook extension 44, 106, 108, which is intended to be inserted into the vertical hook extension 34, 94, 96 formed by the U-profile of the adapter element 30, 90, 92 of the first type during assembly. In order to achieve an advantageous positive and non-positive connection of the vertical hook extension 44, 106, 108 within the vertical hook extension 34, 94, 96, the adapter element 32, 82, 84 of the second type has a horizontal extension 46, 110, 112 formed by a bend.

[0047] The vertical hook extension 34, 94, 96 of the adapter element 30, 90, 92 of the first type, when viewed in the assembled state of the facade system, has a horizontal extension 38 in the facade normal direction 40 of 7 mm and a vertical extension 42 of 25 mm (see Figs. 5 and 6). The vertical extension 42, when viewed in the assembled state of the facade system, is measured from a highest point of a transition area between the horizontal hook extension 62, 124, 128 and the vertical hook extension 34, 94, 96 of the adapter element 30, 90, 92 of the first type and a lowest point of the vertical hook extension 34, 94, 96 of the adapter element 30, 90, 92 of the first type.

[0048] The adapter element 30, 90 of the first type, which is intended to be fastened in an upper region of the facade element 26, 28 of the second type, forms a roof element 50, 116 which, in the assembled state, is arranged directly above a cover side of the facade element 26, 28 of the second type (cf. Figs. 5, 6 and 8).

[0049] The adapter element 32, 84 of the second type, which is intended to be fastened in a lower region of the facade element 26, 28 of the second type, forms a floor element 48, 114, which, in the assembled state, is arranged directly beneath a floor side of the facade element 26, 28 of the second type (see Figs. 5, 7, and 9). Viewed in the assembled state of the facade system, the roof element 50, 116 and the floor element 48, 114 extend horizontally.

[0050] Each facade element 26, 28 of the second type is fastened to the holding device 10 with an additional fastening means 66, preferably with a rivet (see Fig. 5). This prevents undesirable relative movement between the holding device 10 and the facade elements 26, 28 of the second type. However, as an alternative to a rivet connection, other connections deemed appropriate by those skilled in the art are also conceivable. The facade elements 16, 18, 74 are fixed to the holding device 10 accordingly.

[0051] To ensure that the facade elements 16, 18, 74 of the first type and the facade elements 26, 28 of the second type can terminate in a common vertical plane in which a main facade surface lies on a front side of the facade system, the hollow profiles 52, 54 are divided into separate vertical sections, which, when assembled, are connected to one another in an offset manner via pipe connectors 68, 80 (see Figs. 8 and 9). The vertical sections of the hollow profiles 52, 54 for fastening the facade elements 26, 28 of the second type are arranged offset to the rear relative to the vertical sections of the hollow profiles 52, 54 for fastening the facade elements 16, 18, 74 of the first type (see Figs. 8 and 9). For this purpose, the pipe connectors 68, 80 are inserted on one side into the front hollow chambers and on the other side into the rear hollow chambers of the hollow profiles 52, 54 and screwed to them.

[0052] A lower extension 20a, usually present on the facade element 18 of the first type and indicated by dashed lines in Figure 8, is folded upwards so that the facade element 18 of the first type has a closing region with a horizontal leg 70 and a vertical leg 72, viewed in the assembled state of the facade system. Before mounting the facade element 18 of the first type on the holding device 10, the adapter element 82 of the second type is fastened to the lower region of the facade element 18 of the first type thus redesigned, in the present exemplary embodiment advantageously via a rivet connection (not shown in detail). During assembly, the adapter element 82 of the second type is then inserted into the adapter element 90 of the first type, which is fastened to the facade element 26 of the second type.

[0053] Figure 9 shows a further transition from the facade element 28 of the second type downwards to the facade element 74 of the first type in section.

[0054] An upper extension 22a, usually present on the facade element 74 of the first type and indicated by dashed lines in Figure 9, is folded over so that the facade element 74 of the first type has a closing region with a horizontal leg 76 and a vertical, upward-pointing leg 78, as viewed in the assembled state of the facade system. Before mounting the facade element 74 of the first type on the holding device 10, an adapter element 84 of the second type is fastened to the upper region of the facade element 74 of the first type thus redesigned, in the present exemplary embodiment advantageously via a rivet connection (not shown in detail). During assembly, the adapter element 84 of the second type is then inserted into the adapter element 92 of the first type, which is fastened to the facade element 74 of the first type.In the illustrated embodiment, the adapter element 92 of the first type is inserted below the leg 76 of the facade element 74 of the first type and coupled to it from an underside. It would also be conceivable, with a different type of bevel, for the adapter element 92 of the first type to be coupled to an upper side of the leg 76 of the facade element 74 of the first type. At the lower area of ​​the facade system, an extension 86 formed on the facade element 74 is inserted into a closure element 88, which is screwed to the holding device 10.

[0055] The holding device 10 is connected to a bracket (not shown in detail), preferably in the area of ​​the transitions of the offset vertical sections of the hollow profiles 52, 54, with a building wall (not shown in detail).
