Description

Technical field

[0001] The present invention relates to a travel device, in particular an escalator device, comprising a support structure with two opposing side wall units, each with an upper chord, a lower chord, and a side wall extending between the upper chord and the lower chord. The invention further relates to a support structure for such a travel device and to a longitudinal section module of a modularly assembled travel device comprising such a support structure. Background of the invention

[0002] Guideway systems and supporting structures for such systems are generally known from the prior art. These supporting structures form the outer framework for components of the guideway system, such as guides with integrated steps / pallets, drives and electrical components, as well as for attachments and cladding elements. They are typically formed from two opposing side wall units connected by crossbeams. The side wall units usually feature profiles welded together as structural elements, forming truss-like side walls and an upper and lower chord.

[0003] A disadvantage of such support structures is their relatively large manufacturing tolerances, primarily due to the welding of the profiles. Components of the track system that are attached to the support structure must therefore be positioned and / or aligned using complex positioning procedures and appropriate assembly aids before being attached. This requires the use of fasteners for variable positioning / alignment of the component relative to the support structure, or these fasteners must be painstakingly created manually after positioning and / or alignment. In particular, cladding elements for covering the support structure are attached externally using clamps. These clamps must first be positioned and then manually fastened to holes that need to be drilled.

[0004] From EP 1 321 424 B1, a supporting structure for an escalator or moving walkway is known, which has a truss element that is formed in one piece and as a flat, unprofiled, cut plate. The welding work required for the construction of the supporting structure is therefore reduced.

[0005] EP 3 109 195 B1 discloses a support structure for an escalator with several modules, proposing measures in particular regarding connection techniques without thermal distortion in order to achieve low tolerances of the assembled support structure.

[0006] From EP 3 974 369 A1 a supporting structure for an escalator is also known, in which a retaining frame for holding cladding elements is attached to the sides of the supporting structure.

[0007] WO 2022 / 200029 A1 reveals a supporting structure for an escalator. Description of the invention

[0008] Starting from this situation, it is an object of the present invention to enable a simplified and safe positioning / alignment of components of a travel path device.

[0009] The object of the invention is achieved by the features of the independent main claims. Advantageous embodiments are specified in the dependent claims.

[0010] In particular, the problem is solved by a travel path device, especially an escalator device, comprising a supporting structure with two opposing side wall units, each with an upper chord, a lower chord and a side wall extending between the upper chord and the lower chord, and at least one first cladding element for cladding the travel path device from one side, wherein at least one first side wall unit has at least one first connecting means for directly holding the first cladding element on the first side wall unit, wherein the at least one first connecting means is positioned in a defined position relative to a reference point of the supporting structure, and wherein the first cladding element has at least one second connecting means for cooperating with the first connecting means when holding the first cladding element on the first side wall unit.

[0011] Advantageous aspects of the claimed invention are explained below, followed by a description of preferred modified embodiments of the invention. Explanations, particularly regarding advantages and definitions of features, are essentially descriptive and preferred examples, but not limiting ones. If an explanation is limiting, this will be expressly stated.

[0012] Where elements are designated by means of a numbering system, for example, "first element," "second element," and "third element," this numbering is solely for differentiation purposes and does not imply any dependency between the elements or a mandatory sequence. This means, in particular, that a device or method does not need to have a "first element" to have a "second element." The device or method can also have a "first element" and a "third element" without necessarily having a "second element." Multiple units of an element with a single numbering system are also possible, for example, multiple "first elements."

[0013] For the purposes of this disclosure, the general term "travel device" refers primarily to escalators and moving walkways (the latter especially in stepless configurations with at least an approximately level orientation or negligible gradient) as well as related passenger transport devices with an endlessly circulating transport mechanism. A travel device comprises, for example, segments or units forming the transport mechanism, in particular steps or pallets, which are connected to driven chains or comparable drive elements and guided in guides.The guides, as well as a chain (or a similarly acting traction element) and other components of the track system, are held, for example, within support structures that extend longitudinally and essentially laterally. These support structures typically consist of two opposing side wall units connected by crossbeams and, optionally, a base unit. The term "track system" also refers specifically to modular track systems, which are modularly constructed from several longitudinal sections or modules, each with its own individually designed support structure, and can be assembled / mounted module by module.

[0014] The supporting structure of the track system or the respective module is preferably formed essentially by opposing side wall units and connecting crossbeams (also referred to as cross members), wherein each side wall unit is formed by at least one side wall and, in particular, by a top chord and / or a bottom chord. The modular manufacturing process described here can also include the connection of a base unit to the side wall units; however, it has been shown that such a base unit does not necessarily have to fulfill a load-bearing function, but is, for example, designed to collect and, if necessary, drain oil from the drive, or to provide a cover and / or access to the supporting structure from below.is designed to be optimized for the roadway device; in this respect, the ground unit is to be understood as an optional component which can also be functionally separate from the supporting structure, but which can optionally also assume an additional supporting load-bearing function if desired in individual cases.

[0015] The term "side wall" refers to a side structure that, for example, extends at least partially in a single plane, but is alternatively or additionally reinforced, at least partially, by profiles, struts, or beams extending beyond one or more of the planes. Generally, the side wall is formed from structural elements or sections that, as planar sections, absorb forces in multiple directions, and / or, as rod-shaped or strut-like structural elements / sections, absorb the respective forces only along the longitudinal extent determined by their orientation (tension or compression). The side wall can therefore be designed, for example, as a closed surface, as a pure truss, or as a structure with components of closed surfaces and truss structures.Alternatively, at least some of the structural elements / sections of the side wall are formed from flat material, in particular sheet metal, e.g. structurally planar sections or stiffening (in particular) bent L- or U-profile sections in the area of ​​welded connections to other structural elements / sections.

[0016] According to the understanding of this disclosure, a "side wall unit" comprises the aforementioned side wall as well as, as further structural elements / sections, chords associated with this side wall, in particular an upper chord and a lower chord, wherein the chords may be integral with the side wall, integrated, or formed separately from one another. These chords are alternatively also referred to as straps. The respective side wall / unit may also be understood as a side wall / unit provided in modules, depending on the reference to a particular phase of the manufacturing process of the individual modules or the entire track system. In this respect, the term "side wall unit" can refer to the entire side structure encompassing the upper and lower chords, and the term "side wall" can refer to the side structure arranged between the upper and lower chords.

[0017] The terms top chord and bottom chord, which together are also referred to as chords, denote structural elements or sections extending longitudinally in the region of an upper or lower edge of the side wall, respectively, for absorbing loads in the longitudinal direction of the track system, in particular bending loads, which primarily result in tensile stresses in the bottom chord and compressive stresses in the top chord. The chords are preferably designed as profiles or profile sections, in particular as L-profiles, U-profiles, or hollow profiles, and thus exhibit a favorable area moment of inertia for absorbing the bending loads. The chords stiffen the supporting structure and form external corner points, with the chords and / or the side walls optionally serving as attachment points for further components of the track system.The chords can still be designed as components separate from the side wall; however, preferably at least a portion of the chords is formed integrally with the side wall, for example by bending the side wall. Particularly preferably, the top chord is designed as a hollow profile with four walls, wherein two walls are formed by the L-shaped bent side wall, which in this area is made of flat material, and two further walls are formed by a flat material component, also L-shaped and separate from the side wall. Similarly, the bottom chord is preferably designed as a hollow profile with four walls, wherein two walls are formed by the L-shaped bent side wall, which in this area is made of flat material, and two walls are formed by the bottom unit, which is also L-shaped and made of flat material. The components forming the walls are preferably welded together.The upper chord and / or the lower chord can also be provided entirely as a single piece with the side wall or entirely separately from the side wall (especially also in the sense of a procedural variation).

[0018] A cladding element is a flat element used to cover the supporting structure from the outside, particularly from the sides and / or underside. Covering the supporting structure ensures that the walkway system blends aesthetically into its surroundings and protects the supporting structure and its components from unauthorized access. To this end, the cladding elements preferably form a closed outer surface and are not easily removable from the outside. Depending on the installation situation of the walkway system within a building, cladding elements are typically provided on at least one side of the walkway system.

[0019] A fastener is understood to be any device for creating a positive-locking, force-locking, or material-locking connection in at least one spatial direction, wherein the fastener particularly achieves the positioning and alignment of the connected components. For this purpose, the fasteners act, for example, as a stop against which the components meet, simultaneously forming a positive lock, or by means of which the components are positioned against each other for welding.

[0020] Defined positioning means that, during the manufacturing of the track system or support structure, the elements positioned in a defined manner relative to each other are positioned solely with respect to one another. Therefore, if an element such as a recess, a fastener, or a connector is positioned in a defined manner relative to the reference point, only the distance relative to the reference point is considered during manufacturing. Any dimensional inaccuracies of other components / elements are then irrelevant for the positioning of the element. A reference point is understood to be a physical point on a component to which precise positioning is possible in at least one spatial direction. This could be, for example, an edge or corner of a component, a fastener provided on the component, and / or a recess or projection provided in the component.In particular, a round recess is provided as a reference point, which is defined by its center point as a reference point and allows the attachment of an assembly aid such as a bracket or a gauge.

[0021] The solution to the problem with the aforementioned track device now comprises the teaching that a first connecting element, positioned precisely relative to the reference point, is provided on the supporting structure, i.e., on at least one side wall unit. The first connecting element is thus arranged with high dimensional accuracy relative to the reference point, for example, by manufacturing the side wall unit using a correspondingly precise process or by inserting / attaching the first connecting element with a correspondingly precise device. By referencing the first connecting element to the reference point during the manufacturing of the supporting structure, the first connecting element is already provided during the manufacturing of the side wall unit and is thus already positioned for the subsequent positioning and alignment of the first cladding element.The first cladding element then advantageously only needs to be attached to the first connecting element during the further manufacturing of the track system, without the need for any further positioning and alignment measures. This direct fastening eliminates the need for additional fasteners such as clamps or the like.

[0022] The present disclosure is based in particular on the concept that at least a substantial portion of the side walls, defining the overall shape, is formed from flat material, especially sheet metal, wherein at least one reference point is defined on the flat material. Using modern machining methods available for flat materials with very low tolerances, in particular laser cutting, this at least one reference point can be referenced during the subsequent assembly of the guideway device, so that assembly can be carried out with very small tolerances and the guideway device can be manufactured with advantageously high dimensional accuracy.In this way, the comparatively precise relative or absolute positioning of individual components of the track device with respect to at least one reference point can be enabled, and further measures for aligning and positioning the components, especially relative to each other, can be largely dispensed with. In particular, the invention comprises teaching the introduction of further references, in particular the first connecting element (in the sense of additional component-specific mounting reference points), on the flat material in addition to the at least one reference point, which is arranged in the corresponding side wall, using the same machining method. Further components can then be arranged directly on these reference points, and thus in a defined position relative to the at least one (master) reference point, with high accuracy.The references are incorporated, particularly as recesses, even in areas of the flat material that can be subjected to further processing steps, especially bending, following the aforementioned machining method. This allows the referencing concept described here to be implemented for multidimensional positioning in space with respect to at least two or all three spatial directions. Furthermore, the described referencing system offers the advantage of creating a significantly lighter supporting structure compared to conventional truss constructions.

[0023] In one embodiment, the first connecting element is designed to positively lock the first cladding element to the side wall unit. This allows for simple attachment of the first cladding element without the need for additional tools. Such a positive lock is sufficient for securing the first cladding element, as the connecting elements only bear the weight of the cladding element itself. The first and second connecting elements are then designed as simple positive locking elements and correspond accordingly.

[0024] In another embodiment, the first connecting element is designed as a recess. A recess is advantageously easy to form on the side wall unit with particularly high dimensional accuracy relative to the reference point. The second connecting element can then be designed, for example, as a screw or pin. Preferably, however, the second connecting element is designed as a hook for engaging in the recess. The first cladding element can then be hooked into the recesses in a particularly simple manner. In particular, the hook engages behind the recess in such a way that the first cladding element is held in the recess in a form-fitting manner against gravity. The recess is designed, for example, as a vertically arranged slot.

[0025] In a preferred embodiment of the above-described design, the first side wall is essentially formed from a flat material, in particular a metal sheet, with the recess being formed on the first side wall. In particular, the reference point is also formed on the side wall, or the side wall is positioned in a defined manner relative to the reference point. The recess and the reference point can then be positioned relative to each other with high dimensional accuracy, and due to the one-piece construction of the side wall, no further tolerances affect the positioning.

[0026] Particularly preferred is the creation of the recess by means of laser cutting, achieving the dimensional accuracy typical of laser cutting. Insofar as a recess is created by means of laser cutting or a laser cutting tool, the material is cut by a suitably aligned and designed laser beam. A (suitable) laser cutting tool is particularly designed for processing from one direction, with a laser head oriented perpendicular to the workpiece and movable in a plane parallel to the workpiece relative to it. The laser cutting tool is then preferably intended for processing flat material, and the laser head can also be aligned differently from its perpendicular orientation.A laser cutting tool can also include a laser head that is movable around a workpiece, particularly a profile, with the advantage that recesses can be made in the profile from any spatial direction and regardless of the profile's geometry. Furthermore, it is possible to create recesses in a profile with opposing walls, such as a hollow profile, without the laser beam damaging the wall behind it. Laser cutting of profiles with opposing walls, especially hollow profiles, is also referred to as tube laser cutting.

[0027] In a further preferred embodiment, the guideway device has at least a second cladding element for cladding the guideway device from an underside, wherein the first cladding element has at least a third connecting means for directly holding the second cladding element, and wherein the second cladding element has at least a fourth connecting means for cooperating with the third connecting means when holding the second cladding element to the first cladding element. The second cladding element can then be attached directly to, or is attached to, the first cladding element. Due to the already very precise positioning of the first cladding element on the support structure, a correspondingly precise positioning of the second cladding element on the first cladding element is possible without the need for additional connecting means on the support structure.The second cladding element is attached to the first cladding element without any additional aids or fasteners besides the third and fourth fasteners. Preferably, first cladding elements are provided on both sides of the supporting structure, with a second cladding element being attached to two such first cladding elements.

[0028] In a preferred embodiment, the third connecting element is designed to positively lock the second cladding element to the first cladding element. This allows for the simple attachment of the second cladding element without the need for additional tools. Such a positive lock is sufficient for securing the second cladding element, as the connecting elements only bear the weight of the cladding element itself. The third and fourth connecting elements are then designed as simple positive locking elements and correspond accordingly to each other.

[0029] Preferably, the third connecting element is designed as a recess and the fourth connecting element as a hook for engaging the recess. Such a recess can advantageously be formed with high dimensional accuracy on the first cladding element, for example, by laser cutting. The second cladding element can then be easily hooked into the first cladding element. In particular, the hook engages behind the recess in such a way that the second cladding element is held in the recess against gravity in a form-fitting manner. The recess is designed, for example, as a slot.

[0030] In a further preferred embodiment, the first cladding element and / or the second cladding element are / are made of a flat material, in particular a sheet metal. Such a flat material is particularly suitable for the purpose of the cladding elements, which are used to cover the supporting structure. Furthermore, as already described with regard to the side wall, the third and fourth connecting elements can be easily and precisely attached to a flat material, especially if they are designed as recesses and / or hooks.

[0031] In a preferred embodiment, the first cladding element and / or the second cladding element each have at least one lateral bend, wherein the second connecting element and / or the fourth connecting element is formed on the lateral bend. Particularly preferably, the second connecting element and / or the fourth connecting element are formed as a projection, in particular as a hook, on a leading edge of the bend by means of laser cutting. The second connecting element and / or the fourth connecting element are then formed in a simple manner and with high dimensional accuracy. In particular, the second connecting element and / or the fourth connecting element are incorporated into the flat material before the bend is formed. The bends lift the cladding elements from the supporting structure by the length of the bend for simplified alignment and stiffen them internally.

[0032] The second, third, and / or fourth connecting element(s) are preferably formed by laser cutting. The high dimensional accuracy achievable through laser cutting allows for the precise positioning / alignment of the first and / or second cladding element on the supporting structure based on the defined positioning of the first connecting element relative to the reference point. The defined positioning thus extends from the supporting structure through the side wall unit to the first cladding element and ultimately to the second cladding element via precisely manufactured components, without requiring any further references during the manufacturing of the track system. In this way, a referencing chain of high-precision manufactured components is created.

[0033] In a further embodiment, the guideway device is designed to be assembled modularly from several longitudinal section modules. For the purposes of this disclosure, the term "longitudinal section module" is to be understood generally as a longitudinal module of the guideway device, i.e., as a module that forms a longitudinal or length section of the guideway device (i.e., a structurally complete component within the corresponding length range). This term therefore encompasses the terms "head module" and "intermediate module." The term "head module" refers to a module arranged at one of the ends of the guideway device and optionally refers to both types of head modules (upper and lower head module, also referred to as upper and lower parts); thus, this term can equally refer to the module at the upper or lower end of the guideway device.Head modules typically extend over the inclination angle of the track system, thus spanning the bend or the transition from the inclined longitudinal section to the respective horizontal section. In this context, the term "platform section" refers to the section of the respective head module that, in its intended arrangement, is aligned at least approximately in a horizontal plane; therefore, when describing the arrangement / alignment of the respective head module, reference is also made to the orientation of this platform section (or its main plane of extension), particularly if the absolute length of the platform section is greater than the absolute length of the inclined section.The term "connecting inclined section," also referred to as a "stub" in the literature, refers specifically to the inclined section intended for connecting / marrying another longitudinal section module. Its length can vary depending on the function of the respective head module. This implies that the individual modules are intended to be connected to each other within the area of ​​the inclined longitudinal section. The general term "longitudinal section" can refer either to a longitudinal section module or to a specific longitudinal section, particularly of the head module (i.e., the platform section or the inclined section).

[0034] The modular design of the track system makes it possible, in particular, to design modules as standard parts and to ensure that the entire track system only needs to be handled at a late stage during manufacturing.

[0035] The task is also solved by a support structure for a previously described travel path device. The support structure therefore comprises, in particular, two opposing side wall units, each with an upper chord, a lower chord, and a side wall extending between the upper and lower chords, as well as the first connecting element. The support structure offers the advantages described with respect to the travel path device. In particular, a first cladding element and / or, indirectly, a second cladding element can be easily, securely, and with high dimensional accuracy positioned / aligned on it.

[0036] The problem is further solved by a longitudinal section module of a modularly assembleable travel device, in particular an escalator device, comprising a previously described support structure. Such a longitudinal section module exhibits the advantages previously described with respect to the travel device and the support structure. In particular, a longitudinal section module is provided with a connecting element serving as a reference point for forming a load-bearing module connection between the longitudinal section module and another longitudinal section module, or the connecting element is positioned relative to the same reference point. The other longitudinal section module can then have a corresponding absolute reference point or reference an absolute reference point of the longitudinal section module, preferably also referencing the absolute reference point during the assembly of the travel device.Preferably, the longitudinal section module is designed as an intermediate module between two head modules. Brief description of the drawings

[0037] The invention is explained in more detail below with reference to the accompanying drawings and preferred embodiments. The term "figure" is abbreviated as "Fig." in the drawings.

[0038] The drawings show Fig. 1a a perspective view of a partially assembled head module of a modularly assembled track system with a support structure; Fig. 1b a perspective view of a partially assembled intermediate module of a modularly assembled track system with a support structure; Fig. 1c a perspective view of another partially assembled head module of a modularly assembled track system with a support structure; Fig. 1a a detailed view of a support structure according to Figs. 1a to 1c; and Fig. 2 an exploded view of cladding elements that can be attached to / are attached to the supporting structure. Detailed description of the drawings

[0039] The Figures 1a to 1c Figure 1 shows several longitudinal section modules 1.1, 1.2, 1.3 of a modularly assembled track device 1, namely Figure 1a a first longitudinal section module 1.1 designed as a lower head module, Figure 1b a second longitudinal section module 1.2 designed as an intermediate module and Figure 1cA third longitudinal section module 1.3, designed as an upper head module, is included. The head modules extend beyond the bends or have a bent stub. The longitudinal section modules 1.1, 1.2, and 1.3 each have a supporting structure 2 with two side wall units 2.1 and 2.2, each extending primarily in a longitudinal direction L, and crossbeams 2.3 extending in a transverse direction Q. Each side wall unit 2.1 or 2.2, in turn, has a side wall 3, an upper chord 4.1 extending in the longitudinal direction L, and a lower chord 4.2 extending in the longitudinal direction L.

[0040] The construction of the supporting structures 2 is described in the Figure 1dshown in detail. The side wall 3 is formed from a flat material in which structural sections 6.1 and 6.2 are formed by cutouts. The structural sections 6.1 thus divide the side wall 3, or the side wall units 2.1 and 2.2, into panels. Furthermore, structural posts 7 with load-bearing elements 7.1 and the cross braces 2.3 are arranged or attached to the structural sections 6.1, in particular by welding.

[0041] The side wall 3 is integrally formed with the upper chord 4.1 and the lower chord 4.2. Thus, the flat material forming the side wall 3 creates a first wall 8.1, and a second wall 8.2 of the upper chord 4.1 is formed by bending it in an L-shape from the first wall 8.1. A third wall 8.3 and a fourth wall 8.4 of the upper chord 4.1 are formed by another element made from an L-shaped bent flat material and welded to the flat material forming the side wall 3. Similarly, the flat material forming the side wall 3 forms a first wall 9.1, and a second wall 9.2 of the lower chord 4.2 is formed by bending it in an L-shape from the side wall 3. A third wall 9.3 and a fourth wall 9.4 of the bottom chord 4.2 are formed by an L-shaped curved bottom unit 10.

[0042] Again, with reference to the Figures 1a to 1cThe longitudinal section modules 1.1, 1.2, 1.3 are shown with several components of the track device. For example, the lower head module ( Fig. 1a ) a comb plate 12, a base 13, a balustrade 16 with a handrail 17 mounted on it, and several guides 14.1, 14.2, 14.3 for chain rollers, step / pallet rollers, and / or a handrail (not shown). Corresponding guides 14.1, 14.2, 14.3, a base 13, and a balustrade 16 are also included in the intermediate module ( Fig. 1b ) arranged. The guides 14.1, 14.2, 14.3 rest on the support elements 7.1. The upper head module ( Fig. 1c In addition to the components already present in the lower head module and / or intermediate module, the upper head module features a drive 15 for powering a chain and / or a handrail. The balustrade 16 provided for in the upper head module is not shown.

[0043] The longitudinal modules 1.1, 1.2, 1.3 each have reference points 18 embedded in the flat material on the supporting structures 2, or side wall units 2.1, 2.2, or side walls 3, which are located in Fig. 1d are depicted. In the Figures 1a to 1cThe reference points 18 are covered by mounting brackets 19, which in turn are attached to slides 20. By suspending the longitudinal sections 1.1, 1.2, 1.3 at the reference points 18, it is possible to refer to the reference points 18 repeatedly during assembly, ideally exclusively when positioning / aligning components. The reference points 18 are formed on the flat material during the manufacturing of the side walls 3 by laser cutting. Due to the accuracy typical of laser cutting, all other recesses or cutouts in the flat material are positioned exactly opposite the reference points 18 and can therefore also serve as references for positioning / aligning components. This applies in particular to the connecting elements 21 provided for joining the longitudinal section modules 1.1, 1.2, 1.3 and slots 22 for receiving components of the travel device 1, such as the support elements 7.1.By means of the reference points 18 and in particular the suspension of the longitudinal section modules 1.1, 1.2, 1.3, an exact alignment of the longitudinal section modules 1.1, 1.2, 1.3 to each other is also made possible when connecting them to each other via the connecting means 21.

[0044] Figure 2Figure 1 shows an exploded view of the supporting structure 2 and the cladding elements 23.1 and 23.2 to be arranged on the first side wall unit 2.1, namely a first cladding element 23.1 designed as a side cladding element and a second cladding element 23.2 designed as a lower cladding element. The cladding elements serve to cover the supporting structure 2 for aesthetic and safety reasons. In the side wall 3 of the supporting structure, in addition to the reference points 18 and other references, such as the slots 22, first fasteners 24.1 designed as slot-shaped recesses are arranged. The first fasteners 24.1 are formed during the production of the side wall 3 from a flat material by laser cutting with a defined position relative to the reference point 18 and are designed for the dimensionally accurate, direct attachment of the first cladding element 23.1. The first cladding element 23.The first cladding element 23.1, which is formed from a flat material with bends 25 on vertical sides, has second connecting elements 24.2 designed as hooks on the bends 25. The second connecting elements 24.2 are formed on the flat material by laser cutting before the bend 25 is formed. The second connecting elements 24.2 engage with and behind the first connecting elements 24.1 to fasten the first cladding element 23.1 to the side wall 3, forming a positive fit 26.

[0045] Furthermore, the first cladding element 23.1 has third connecting elements 24.3 formed as slot-shaped recesses on one lower side. The second cladding element 23.2, like the first cladding element 23.1, is formed from a flat material with flanges 27. The fourth connecting elements 24.4 are formed as hooks on the flanges 27. The fourth connecting elements 24.4 are formed on the flat material by laser cutting before the flanges 27 are formed. To fasten the second cladding element 23.2 to the first cladding element 23.1, the fourth connecting elements 24.4 engage with and behind the third connecting elements 24.3 to form a positive connection 28.
