Description

PANEL ELEMENT, COMPOSITE PANEL COMPRISING PANEL ELEMENTS, AND ENCLOSURE FOR A SCAFFOLDING SYSTEM A panel element, a composite panel comprising at least two panel elements, and an enclosure for a scaffolding system comprising at least one panel element are described. So-called enclosure panels are known for scaffolding systems, which, for example, can be attached to the outer side of a scaffold, climbing formwork, or a building under construction or restoration to enclose the scaffolding or the building under construction or restoration, and which can serve to ensure safety as well as provide privacy and / or protection from environmental influences, such as wind and sunlight. Such enclosure panels usually feature a frame structure and are typically mounted using screw fasteners or clamps. If walkable platforms are to be attached to the enclosure panels using brackets, additional recessed vertical struts within the frame structure are usually necessary to secure the platforms side by side to the enclosure panels. On these frame vertical struts, which, as is common with frame formwork, are directly connected to one another, it is not possible to attach two brackets directly next to each other. Consequently, additional fasteners are required for mounting platform brackets, resulting in a complex design in terms of geometry and operation. Furthermore, it is difficult to adjust the height of the platforms variably when floor heights vary. Therefore, a simpler design for such panels is desirable. At least one object of certain embodiments is to provide a panel element, for example for an enclosure, in particular for a scaffolding system. Further objects of certain embodiments are to provide a composite panel comprising at least two panel elements and an enclosure comprising at least one panel element, in particular an enclosure for a scaffolding system. These objects are solved by the subject-matters according to the independent patent claims. Advantageous embodiments and further developments of the subject-matters are described in the dependent claims and become further apparent from the following description and the drawings. According to at least one embodiment, a panel element is disclosed. The panel element may, for example, be intended and configured for an enclosure, in particular for an enclosure for a scaffolding system. According to at least one further embodiment, a composite panel comprising at least two panel elements is disclosed. According to at least one further embodiment, an enclosure for a scaffolding system comprising at least one panel element or at least one composite panel is disclosed. The scaffolding system may include the enclosure, such that the enclosure may be part of a scaffolding system. The following description refers equally to the panel element, the composite panel, the enclosure for the scaffolding system, and the scaffolding system. To form the composite panel, at least two panel elements are arranged next to one another so that the panel elements are adjacent to one another. Preferably, the panel elements may be adjacent to one another and mechanically connected to form the composite panel. Preferably, the at least two panel elements may be connected to one another by at least one connector, and most preferably by two connectors. In particular, the at least one connector may be intended and configured to mechanically secure two panel elements together. For that, the at least one connector may comprise a first connection region for mechanically connecting the connector to a first of the two panel elements and a second connection region for mechanically connecting the connector to a second of the two panel elements. A mechanical connection may, in particular, refer to a form-fit connection, a force-fit connection or a combination of formfit and force-fit connections. By means of the at least one connector, two panel elements that are directly adjacent to one another in the composite panel can thus be mechanically connected to one another and thereby secured together. It is particularly preferred that two panel elements be connected to one another using two similarly designed connectors. It is particularly preferred that the connection between two panel elements can be released by removing the connector(s) from at least one of the panel elements, so that the composite panel can be disassembled into individual panel elements accordingly. The scaffolding system may, for example, comprise a formwork system or, alternatively, may be part of a formwork system. Formwork systems for erecting structures are used to produce building components, such as walls or ceilings, and are generally configured to create a filling space for a hardenable building material, such as concrete. The building material can be poured into the filling space and, after it has hardened, form the desired building component. Alternatively or additionally, the formwork system may comprise a climbing system or may be part of a climbing system. Climbing systems are devices configured to climb up building walls, for example to perform renovation or cleaning work or, in particular, to be used in building construction to erect the building walls along which the climbing system ascends. For example, in building construction, wall parts are erected in stages; once these have hardened, the climbing system can ascend them to continue erecting the building. The enclosure may be attached to the scaffolding system and serve, for example, as an access point, a walking surface and / or, with the protective functions described below, as a protective system and / or safety system for construction work or other purposes. The panel element described below and, in particular, the composite panel comprising at least two panel elements and the enclosure can, for example, be mounted on a side of the building that is external as viewed from the building itself, to serve as a safety system, such as fall protection, for persons on the scaffolding system. Furthermore, the panel element, and in particular a composite panel comprising at least two panel elements, and the enclosure can also serve as a privacy screen and / or as protection against environmental influences, such as weather protection, sun protection, wind protection, thermal insulation, cold protection and / or noise protection. Similarly, protection of the surrounding area, for example, against noise, can be provided. Furthermore, the panel element, and in particular a composite panel comprising at least two panel elements, and, accordingly, the enclosure can also serve, for example, as an advertising space on the scaffolding system. According to a further embodiment, the panel element comprises a profile frame. The profile frame may, particularly preferred, have a rectangular shape. The profile frame may be formed from multiple frame elements. Preferably, the profile frame comprises a first horizontal frame element, a second horizontal frame element and two vertical frame elements. Most preferably, the profile frame is formed from two horizontal frame elements and two vertical frame elements that are connected to one another to form a rectangular shape. In other words, the horizontal frame elements may preferably be parallel to one another, and the vertical frame elements may preferably be parallel to one another. Each of the horizontal frame elements has a main extension direction that runs along a horizontal direction, and each of the vertical frame elements has a main extension direction that runs along a vertical direction. Terms such as “horizontal” and “vertical,” as well as “top” and “bottom,” may refer here and in the following, unless otherwise specified, specifically to the orientation when one or more panel elements are installed as intended in the composite panel and as part of the enclosure for the scaffolding system. The horizontal direction thus constitutes a transverse direction, and the vertical direction constitutes a longitudinal or height direction. A depth direction can be defined perpendicular to the horizontal and vertical directions. The first horizontal frame element preferably forms a lower frame rail, which, when installed as intended within the enclosure for the scaffolding system, runs horizontally and from which the two vertical frame elements extend vertically upward to the second horizontal frame element, which forms an upper frame rail that also runs horizontally. The two vertical frame elements accordingly form side frame rails. The vertical frame elements are preferably arranged along the vertical direction between the first horizontal frame element and the second horizontal frame element and are connected to the horizontal frame elements. Alternatively, the horizontal frame elements may also be arranged along the horizontal direction between the vertical frame elements and connected to the vertical frame elements. According to a further embodiment, each of the vertical frame elements has a vertical end region on both sides along the vertical direction and preferably terminates on both sides along the vertical direction with a vertical end region. The horizontal frame elements may each have a horizontal end region on both sides along the horizontal direction and, most preferably, terminate on both sides along the horizontal direction with a horizontal end region. Furthermore, each of the vertical end regions may preferably abut a surface of one of the horizontal frame elements that is perpendicular to the vertical direction. The vertical frame elements are fastened to each of the horizontal frame elements, preferably with the vertical end regions. Alternatively, each of the horizontal end regions may abut against a surface of one of the vertical frame elements that is perpendicular to the horizontal direction. In this case, the horizontal frame elements are fastened to each of the vertical frame elements, preferably with the horizontal end regions. A preferably permanent fastening may preferably comprise welding and / or riveting. Furthermore, the horizontal frame elements and the vertical frame elements may also be connected to one another by means of screw connections and / or bolted connections. In particular, the enclosure for the scaffolding system may include at least one support that is attached, for example, to a building, a part of a building, or to the scaffolding system itself. Furthermore, the support may also be part of the scaffolding system. For example, the support may be a vertical support. The panel element, and preferably the composite panel, may be fastened directly or indirectly to the support, for example via one or more braces. These may, for example, be bolted or screwed braces that can be fastened directly to a profile frame of one or more panel elements and to a support of the scaffolding system’s enclosure. Each of the horizontal frame elements may be a profile element that may be selected from a hollow profile such as a square profile, a U-profile, a Z-profile, an L-profile, an I-profile or a combination of several similar or different types of the aforementioned or other profiles. Preferably, each of the horizontal frame elements comprises a U-profile or a square profile or is such a profile. More particularly, each of the horizontal frame elements may additionally comprise an I-profile or an L-profile that may adjoin the U-profile or the square profile along the vertical direction. In particular, for each of the horizontal frame elements, the U-profile or the square profile may be formed integrally with the I-profile or the L-profile. In particular, the horizontal frame elements may be provided with mounting holes that are intended and configured to accommodate retaining elements. Here and hereinafter, a retaining element may be selected, in particular, from bolts, screws, rivets and pins. As described above, the at least one connector for forming a composite panel may be intended and configured to mechanically connect a horizontal frame element of one panel element to a horizontal frame element of another panel element. Through fastening openings in the connector, the connector can be secured to the horizontal frame elements by means of retaining elements that can be inserted through the mounting holes of the horizontal frame elements and through the fastening openings, thereby establishing the mechanical connection to the panel elements and, consequently, between the panel elements. In particular, each of the horizontal frame elements may have a plurality of mounting holes arranged along the horizontal direction. The mounting holes may each be formed in two opposing surfaces of a horizontal frame element that are perpendicular to the vertical direction. For example, the opposing surfaces may be surfaces of a U-profile, an L-profile and an I-profile, of two L-profiles or two I-profiles, or, preferably, of a square profile. The mounting holes may preferably be arranged at uniform intervals along the horizontal direction. Furthermore, the mounting holes may also be arranged irregularly. Each of the vertical frame elements may be a profile element that can be selected from a hollow profile such as a square profile, a U-profile, a Z-profile, an L-profile, an I-profile, or a combination of several of similar or different types of profiles mentioned. In particular, each of the vertical frame elements comprises at least one vertical frame part, which is preferably strip-shaped and extends from the first to the second horizontal frame element, i.e., it has a main extension direction along the vertical direction like the vertical frame element as a whole. The vertical frame part is preferably strip-shaped and, in particular, flat, and furthermore extends preferably along a plane perpendicular to the horizontal direction. In other words, the strip-shaped vertical frame part of each of the vertical frame elements is oriented such that its two main surfaces are perpendicular to the horizontal direction. If the profile elements of the vertical frame elements each consist solely of the vertical frame part, the vertical frame elements are preferably designed as I-profiles. Furthermore, each of the vertical frame elements may comprise a first leg part, which is preferably strip-shaped and, in particular, flat, and which adjoins the vertical frame part in a direction along the depth direction. The first leg part adjoins the vertical frame part via an edge that extends along the vertical direction. The vertical frame part and the first leg part may preferably adjoin one another at an angle, most preferably at an angle of 90°. Accordingly, the first leg part of each of the vertical frame elements may extend along a plane perpendicular to the depth direction. If the profile elements of the vertical frame elements are each formed from the vertical frame part and the first leg part, the vertical frame elements are preferably designed as L-profiles. Furthermore, each of the vertical frame elements may comprise a second leg part, which is preferably strip-shaped and, in particular, flat, and which adjoins the vertical frame part in a direction along the depth direction opposite the first leg part. The vertical frame part and the second leg part may preferably adjoin one another at an angle. The first leg part and the second leg part adjoin the vertical frame part via edges extending along the vertical direction, adjoining two sides of the vertical frame part that are opposite each other along the depth direction. For example, the vertical frame part and the second leg part may form an acute, right or obtuse angle, with an angle of 90° being preferred. Accordingly, the second leg part of each of the vertical frame elements may extend along a plane perpendicular to the depth direction. If the profile elements of the vertical frame elements are each formed from the vertical frame part, the first leg part and the second leg part, the vertical frame elements are preferably configured as Z-profiles or U-profiles. The first and second leg parts may preferably be parallel to one another. Alternatively, depending on the angle formed between the second leg part and the vertical frame part, the first and second leg parts may also not be parallel to one another. The vertical frame elements may thus preferably comprise one or more strip-shaped parts, one of which is the vertical frame part. When mounted in the profile frame, the stripshaped part or parts have a main direction of extension along the vertical direction. The strip-shaped part or parts in addition to the vertical frame part may be the first leg part or the first and second leg parts. In case of one or two leg parts, the strip-shaped parts of the vertical frame elements are arranged at an angle to one another, preferably perpendicular to one another. In case of a Z-profile, the first and second leg parts adjoin the vertical frame part such that they extend in opposite directions along the horizontal direction, whereby the first and second leg parts need not necessarily be parallel. In this case, the first leg parts of the vertical frame elements may preferably extend away from one another in the horizontal direction, while the second leg parts of the vertical frame elements may extend toward one another in the horizontal direction. In case of a U-profile, the first and second leg parts adjoin the vertical frame part such that they extend in the same direction along the horizontal direction, wherein the first and second leg parts need not necessarily be parallel. The first leg parts of the vertical frame elements may preferably extend away from one another along the horizontal direction, and in this case, the second leg parts of the vertical frame elements may also extend away from one another along the horizontal direction. According to a further embodiment, the vertical frame part of each of the vertical frame elements has a plurality of mounting holes arranged along the vertical direction. It is particularly preferred that the mounting holes be arranged at uniform intervals. Furthermore, the mounting holes may also be arranged irregularly. Like the mounting holes of the horizontal frame elements, the mounting holes of the vertical frame elements may also be provided and configured to receive retaining elements. In particular, the vertical frame elements may be arranged symmetrically with respect to a plane of symmetry perpendicular to the horizontal direction. Specifically, the vertical frame elements may thus be identically constructed and arranged in a mirror-symmetrical manner with respect to a plane of symmetry perpendicular to the horizontal direction within the profile frame. Furthermore, the horizontal frame elements may be intended and arranged symmetrically with respect to a plane of symmetry perpendicular to the vertical direction. As a result, the profile frame may be designed such that, when rotated 180° about an axis of rotation along the depth direction, it becomes its own mirror image, which may facilitate the installation of the panel element. According to a further embodiment, each of the vertical frame elements terminates flush with the horizontal frame elements in the horizontal direction. In particular, this may also mean that the first leg part of each of the vertical frame elements terminates flush with the horizontal frame elements along the horizontal direction. The first leg part of each of the vertical frame elements is preferably arranged flush with the respective closer-set horizontal end region of each of the horizontal frame elements. According to a further embodiment, the vertical frame part of each of the vertical frame elements is set back from the respective, closer-located horizontal end region along the horizontal direction. This ensures that, when panel elements are arranged adjacent to one another in a composite panel, there is a gap between the vertical frame parts of the two directly adjacent vertical frame elements, so that additional components, such as the hinge plates of the bracket elements described below, can be positioned between these vertical frame parts. Furthermore, the horizontal frame elements and the vertical frame elements may abut flush with one another on both sides along the depth direction. For example, on one side along the depth direction, the horizontal frame elements and the first leg parts of the vertical frame elements may be flush. Furthermore, depending on the configuration of the vertical frame elements, on the other side along the depth direction, the horizontal frame elements and, if present, the second leg parts of the vertical frame elements may be flush. According to a further embodiment, the panel element comprises a plate that is attached to the profile frame. The plate may be provided for covering purposes and may be made of a material selected from wood, metal, or plastic. For example, the plate may be a wooden plate, a metal plate, or a plastic plate, or, for example, a composite plate comprising several of the aforementioned materials. The panel may be provided with or without openings. For example, the panel may comprise or be a so-called perforated sheet, which may comprise or be made of a metal. Furthermore, the panel may comprise or be made of expanded metal. In addition, a perforated sheet-like or expanded metal-like configuration in combination with another material, such as wood or plastic, may be possible. In particular, the panel may abut against the vertical frame elements. For example, the panel may abut against the first leg part of each of the vertical frame elements. Furthermore, the panel may be fastened to the vertical frame elements. For example, the panel may be fastened to the first leg part of each of the vertical frame elements. For example, the panel may be fastened using bolts, rivets or screws. Additionally, permanent connections, such as welding, are also possible. According to a further embodiment, the panel element comprises at least one strut extending from one frame element to an opposite frame element. For example, the panel element may comprise at least one cross strut extending from one of the two vertical frame elements to the other of the two vertical frame elements. The at least one cross strut thus preferably extends in the horizontal direction between the vertical frame elements. It is particularly preferred that fastening openings be provided in the vertical frame elements, into which the at least one cross strut is inserted. Furthermore, the panel element may include at least one longitudinal strut extending from one of the two horizontal frame elements to the other of the two horizontal frame elements. The at least one longitudinal strut thus preferably extends along the vertical direction between the horizontal frame elements. It is particularly preferred that fastening openings are provided in the horizontal frame elements, into which the at least one longitudinal strut is inserted. Furthermore, an insert element may be attached to the profile frame, which can be used to achieve desired visual and / or protective effects, such as privacy screening and / or protection of workers from environmental influences such as sunlight, noise, heat, cold, wind, etc., and / or protection of the surrounding area from noise. The insert element may, for example, comprise a material selected from wood, metal or plastic. For example, the insert element may be a wooden panel, a metal panel, a plastic panel, or, for instance, a composite panel comprising several of the aforementioned materials. The insert element may be configured as a flat panel or, for example, as a corrugated panel. The insert element may preferably be secured by at least one strut and, more preferably, by a plurality of struts, i.e., for example by at least one cross strut and, most preferably, by multiple cross struts arranged at a vertical distance from one another. In particular, the insert element may be arranged within the profile frame between the at least one cross strut and the panel. The insert element may further adjoin the vertical frame part of each of the vertical frame elements and the horizontal frame elements, thereby covering a rectangular area enclosed by the horizontal frame elements and the vertical frame elements. According to a further embodiment, at least one foldable bracket element is attached to the profile frame. In particular, the bracket element may be attached to a vertical frame element. It is particularly preferred that a folding platform be attached to the profile frame. The folding platform may comprise two foldable bracket elements and a base element attached to the bracket elements. In particular, one of the foldable bracket elements may be attached to each of the two vertical frame elements. When unfolded, the folding platform may serve, for example, as a stage, i.e., as a platform for workers. Particularly preferably, a bracket element may be secured to each of the vertical frame elements, specifically to the vertical frame part of the vertical frame elements, by means of a retaining element. To this end, each of the bracket elements may include a hinge element that is rotatably secured by means of a retaining element in a mounting hole in the vertical frame part of one of the vertical frame elements. To this end, the hinge elements may comprise hinge openings for the retaining elements. This allows for easy assembly and disassembly, as well as flexible height adjustment independent of other panel elements within a composite panel. In particular, each of the hinge elements may comprise two hinge plates that together partially encompass the respective vertical frame element. This may mean, in particular, that the vertical frame part of a vertical frame element is positioned horizontally between the two hinge plates of a bracket element. Furthermore, the respective hinge element of the bracket elements may be embodied to be firmly connected to a retaining element. In particular, the respective hinge element of the bracket elements may comprise a hinge plate that is firmly connected to a retaining element, preferably a bolt or a screw, for example by welding or as a one-piece construction. It is particularly preferred that the retaining elements of the hinge elements of the two bracket elements point in the same direction, so that the folding platform can be hung from one side into the vertical frame elements, i.e., into mounting holes in the vertical frame parts of the vertical frame elements, and mounted so as to rotate, and can be secured by retaining elements such as spring retainers or nuts. In other words, the retaining elements can be inserted into the mounting holes of the vertical frame elements from one side, much like the hinges of a door, and secured on the other side. Furthermore, each of the bracket elements may have a support surface on which the base element is positioned. For example, the base element may be screwed to the support surfaces. In addition, the base element may have slot-shaped openings through which the base element is slid onto connecting areas of the bracket elements, wherein, for each of the bracket elements, the connecting area is located between the hinge element and the support surface. Furthermore, each of the bracket elements may have a support surface that, when the base element is in the unfolded position, rests against the vertical frame element, for example against a second leg part of a vertical frame element. Thereby, the folding platform can be supported in its unfolded state by the vertical frame elements and, if present, by the second leg parts of the vertical frame elements. In a folded-up position, the folding platform can be temporarily secured. For example, the base element can be secured in the folded-up position, for instance by a rope attached to a horizontal frame element. Furthermore, a clamping mechanism may also be present. Alternatively or additionally, for example, the hinge element of each bracket element may have retaining openings with which the hinge elements, and thus the folding platform, can be secured in the folded-up position. In the composite panel, the at least two panel elements may be directly adjacent to one another in the horizontal direction and connected to one another. In particular, the first leg part of a vertical frame element of one of the two panel elements and the first leg part of a vertical frame element of the other of the two panel elements may be directly adjacent to one another. Because the vertical frame parts of the vertical frame elements are set back horizontally from the ends of the horizontal frame elements along the horizontal direction, as described above, it is possible to attach folding platforms located side by side directly to the vertical frame elements of the adjacent panel elements using the hinge elements. The vertical frame elements thus form functional vertical edge struts that are suitable for attaching two adjacent stage consoles directly to two neighboring panel elements. Further advantages, advantageous embodiments, and further developments are apparent from the exemplary embodiments described below in conjunction with the figures. Figure 1 shows a schematic illustration of a composite panel according to an embodiment, Figures 2A to 2D show schematic illustrations of a panel element according to a further embodiment, Figures 3A to 4B show schematic illustrations of a panel element according to further embodiments, Figures 5A to 5C show schematic illustrations of a composite panel according to a further embodiment, Figures 6A to 6C show schematic illustrations of a panel element according to further embodiments, Figures 7A and 7B show schematic illustrations of a composite panel according to a further embodiment, Figures 8A to 8C show schematic illustrations of a panel element according to a further embodiment, Figures 9A to 10B show schematic illustrations of an enclosure according to a further embodiment. In the embodiments and figures, identical, similar, or functionally equivalent elements may be designated by the same reference signs. The elements shown and their relative dimensions are not to be considered to scale; rather, individual elements, such as layers, components, structural elements and regions, may be depicted as exaggeratedly large for better visualization and / or understanding. In Figure 1 a schematic illustration of a composite panel 200 according to an embodiment is shown. The composite panel 200 may, in particular, be part of an enclosure for a scaffolding system, which will be explained in connection with some embodiments below. Specifically, the composite panel 200 comprises at least two panel elements 100 that can be connected to one another by means of at least one connector 30. In Figure 1, for clarity, the panel elements 100 and the connector 30 are shown in a state in which they are not yet mechanically connected to one another, with the functional connection between the panel elements 100 and the connector 30 indicated by the double arrows. In particular, the connector 30 comprises a first connection region 31 for mechanically connecting the connector 30 to a first of the two panel elements 100 and a second connection region 32 for mechanically connecting the connector 30 to a second of the two panel elements 10. A mechanical connection may, in particular, refer to a form-fit and force-fit connection. Each of the panel elements 100 comprises a profile frame 1, as described in detail below. The profile frame 1 of each of the panel elements 100 may preferably have a rectangular shape and be formed from several frame elements, most preferably from two horizontal frame elements 10 and two vertical frame elements 20, which are connected to one another to form the rectangular shape. Terms such as “horizontal” and “vertical,” as well as “top” and “bottom,” refer here and throughout the following, unless otherwise specified, to the intended installation of the panel elements 100 in the composite panel 200 and as part of the enclosure for a scaffolding system. Accordingly, in some figures, the horizontal direction 91 and the vertical direction 92 are indicated to suggest the intended orientation of the panel elements. Additionally, in the following figures, a depth direction 93 may be indicated, which is perpendicular to the horizontal direction 91 and perpendicular to the vertical direction 92. The figures described below refer to particularly preferred embodiments of the panel element 100, for example with respect to the profile frame 1 and the horizontal frame elements 10 and the vertical frame elements 20. As an alternative to the described embodiments, the panel element 100 may also include additional or different features as described in the general part, even if these are not explicitly shown or described below. Figures 2A to 2D show schematic illustrations of different views of a panel element 100 according to an embodiment. Figure 2A shows a three-dimensional view of the panel element 100. Figures 2B, 2C, and 2D show detailed views of parts of the panel element 100. The following description refers equally to Figures 2A through 2D. As described above, the panel element 100 comprises a profile frame 1 formed by two horizontal frame elements 10 and two vertical frame elements 20, which are connected to one another to form a rectangular shape. Each of the horizontal frame elements 10 has a main extension direction that extends along the horizontal direction 91. Each of the vertical frame elements 20 has a main extension direction that extends along the vertical direction 92. Perpendicular to the horizontal and vertical directions 91, 92, a depth direction 93 is defined, as described above. A first of the horizontal frame elements 10 forms a lower frame rail that, when the panel element 100 is installed as intended in an enclosure for a scaffolding system, extends horizontally, and from which the two vertical frame elements 20 extend perpendicularly upward toward the second of the horizontal frame elements 10, which forms an upper frame rail that also extends horizontally. The two vertical frame elements 20 correspondingly form lateral frame rails. As can be seen, for example, in Figures 2C and 2D, the vertical frame elements 20 are preferably arranged along the vertical direction between the lower first horizontal frame element 10 and the upper second horizontal frame element 10. The horizontal frame elements 10 have facing surfaces 14 on which the vertical frame elements 20 rest. In particular, the vertical frame elements 20 have vertical end regions 25, with which each of the vertical frame elements 20 terminates on both sides along the vertical direction 92 and which are connected to the horizontal frame elements 10. For example, the frame elements may be permanently connected to one another by welding, riveting or screwing or a combination thereof. Thus, each of the vertical end regions 25 abuts a surface 14 of one of the horizontal frame elements 10, which is formed perpendicular to the vertical direction 92. Alternatively, the horizontal frame elements 10 may also be arranged along the horizontal direction 91 between the vertical frame elements 20. Each of the horizontal frame elements 10 is preferably a profile element that can be selected from a hollow profile such as a square profile, a U-profile, a Z-profile, an L-profile, an I-profile or a combination of several of the same or different types of profiles mentioned. In the illustrated embodiment, the horizontal frame elements 10 are embodied as hollow profiles, specifically as square profiles 11, as can be seen in particular in Figures 2C and 2D. Alternatively, the horizontal frame elements 10 may also be embodied, for example, as U-profiles or combinations of I-profiles and L-profiles, wherein the horizontal frame elements 10 preferably have surfaces 14 facing one another, regardless of the type of profile. Furthermore, the horizontal frame elements 10 have mounting holes that are intended and configured to accommodate retaining elements such as bolts, screws, rivets and / or pins. In particular, the horizontal frame elements 10 may be configured such that connectors 30, as described in connection with Figure 1, can be inserted and / or mounted externally to connect panel elements 100 into a composite panel 200. Through fastening openings in the connectors, these can be secured to the horizontal frame elements 10 using retaining elements that can be inserted through the mounting holes 18 of the horizontal frame elements 10 and through the fastening openings, thereby establishing a mechanical connection to the panel elements 100 and, consequently, between the panel elements 100 themselves. As can be seen in Figures 2C and 2D, the horizontal frame elements 10 have horizontal end regions 15, with which the horizontal frame elements 10 terminate on both sides along the horizontal direction 91 and in which recesses 19 are formed, which are intended and configured so that a part of a connector can engage, in order to achieve, together with a retaining element, a play-free fastening within the horizontal frame element 10. In particular, as shown, each of the horizontal frame elements 10 may have a plurality of mounting holes 18 arranged along the horizontal direction 91. The mounting holes 18 may preferably be formed in two opposing surfaces of a horizontal frame element 10, which are perpendicular to the vertical direction 92. For example, the opposing surfaces may be surfaces of a U-profile, an L-profile, and an I-profile, of two L-profiles or two I-profiles, or, preferably, as in the present embodiment shown in Figures 2A to 2D, of a square profile 11. The mounting holes 18 may preferably be arranged at uniform intervals along the horizontal direction 91. Alternatively, the mounting holes 18 may also be arranged unevenly, for example in groups. The vertical frame elements 20 are, as shown in part in Figure 2B, preferably embodied as Z-profiles 21. Each of the Z-profiles 21, and thus each of the vertical frame elements 20, comprises three strip-shaped parts 22, 23, 24, which, when the panel element 100 and thus the profile frame 1 are mounted as intended, have a main extension direction along the vertical direction 92. When viewed along the vertical direction 92, i.e., along the main extension direction of the Z-profiles, the strip-shaped parts 22, 23, 24 of each vertical frame element 20 are arranged adjacent to one another and at an angle to one another, particularly preferably perpendicular to one another. In particular, each of the Z-profiles 21 may include a vertical frame part 22 formed by one of the strip-shaped parts. A first leg part 23 and a second leg part 24, formed by the other two stripshaped parts, are arranged at an angle to the sides of the vertical frame part that are opposite to each other along the depth direction 93. The vertical frame part 22, the first leg part 23, and the second leg part 24 are preferably each formed to be flat. The first and second leg parts 23, 24 thus abut against two sides of the vertical frame part 22 that are opposite to each other along the depth direction 93 via edges extending along the vertical direction 92, and preferably each form an angle of 90° with the vertical frame part 22. In particular, the first and second leg parts 23, 24 abut the vertical frame part 22 such that they extend in opposite directions along the horizontal direction 91. In other words, the first leg part 23 of one vertical frame element 20 extends along the horizontal direction 91 away from the other vertical frame element 20, while the second leg part 24 of that same vertical frame element 20 extends along the horizontal direction 91 toward the other vertical frame element 20. When the panel element 100 is mounted in an enclosure for a scaffolding system, the vertical frame part 22 thus preferably extends along a plane perpendicular to the horizontal direction 91, and the two leg parts 23, 24 extend along respective planes perpendicular to the depth direction 93 and are formed parallel to one another. The first leg parts 23 of the vertical frame elements 20 extend away from one another along the horizontal direction 91, while the second leg parts 24 of the vertical frame elements 20 extend toward one another along the horizontal direction 91. In particular, the vertical frame elements 20 are arranged symmetrically with respect to a plane of symmetry perpendicular to the horizontal direction 91 and are identically configured. The vertical frame elements 20 are thus arranged in a mirror-symmetrical manner within the profile frame 1. Furthermore, the horizontal frame elements 10 are also embodied and arranged symmetrically with respect to a plane of symmetry perpendicular to the vertical direction 92 and are of identical construction, so that the horizontal frame elements 10 are also arranged in a mirror-symmetrical manner within the profile frame 1. The profile frame 1 is thus symmetrical with respect to both planes of symmetry, which are perpendicular to the horizontal direction 91 and perpendicular to the vertical direction 92. As a result, the profile frame is embodied such that, when rotated 180° about an axis of rotation along the depth direction 93, it becomes its own mirror image, which can facilitate the installation of the panel element 100. The vertical frame part 22 of each of the vertical frame elements 20 has a plurality of mounting holes 28 arranged along the vertical direction 92. It is particularly preferred that the mounting holes 28 be arranged at uniform intervals, as shown. Alternatively, the mounting holes 28 may also be spaced at irregular intervals. Like the mounting holes 18 of the horizontal frame elements 10, the mounting holes 28 of the vertical frame elements 20 may also be intended and configured to receive retaining elements. The vertical frame elements 20 additionally comprise fastening openings 29 into which cross struts 4 can engage to secure an insert element 3 in the profile frame 1 on the panel 2, as shown in conjunction with Figures 4A and 4B. Each of the vertical frame elements 20 terminates flush with the horizontal frame elements 10 in the horizontal direction 91. This means that the first leg part 23 of each of the vertical frame elements 20 terminates flush with the horizontal frame elements 10 along the horizontal direction 91, as can be seen, for example, in Figure 2D. The first leg part 23 of each of the vertical frame elements 20 is thus arranged flush with the respective, more closely spaced horizontal end region 15 of each of the horizontal frame elements 10. The vertical frame part 22 of each of the vertical frame elements 20 is therefore set back along the horizontal direction 91 from the respective, closer-located horizontal end region 15, as can be seen in particular in Figure 2D. Furthermore, the horizontal frame elements 10 and the vertical frame elements 20 can abut flush with one another on both sides along the depth direction 93, as can also be seen in particular in Figure 2D. Thus, on one side along the depth direction 93, the horizontal frame elements 10 and the first leg parts 23 of the vertical frame elements 20 may be flush, and on the other side along the depth direction 93, the horizontal frame elements 10 and the second leg parts 24 of the vertical frame elements 20 may be flush. As an alternative to the shown embodiment, in the vertical frame elements 20, for example, the second leg part 24 may form an angle other than 90° with the vertical frame part 22, and thus form an acute or obtuse angle. Furthermore, the first and second leg parts 23, 24 may, for example, extend in the same direction along the horizontal direction 91 away from the vertical frame part 22, so that the vertical frame elements 20 can be formed as U-profiles. In this case, it is particularly preferred that the second leg part 24 be arranged set back along the horizontal direction 91 from the respective closer-lying horizontal end region 15. This may mean that the second leg part 24 is shorter and thus narrower than the first leg part 23 and / or that the second leg part 24 forms an acute angle with the vertical frame part 22 and thus runs diagonally across the surfaces 14 of the horizontal frame elements 10. Furthermore, the vertical frame elements 20 may, for example, comprise only the vertical frame part 22 and the first leg part 23, so that the vertical frame elements 20 can be configured as L-profiles. As shown in Figures 3A and 3B, which correspond to the views in Figures 2C and 2D, based on a further embodiment, the horizontal frame elements 10 may, for example, also comprise a combination of a square profile 11 and an L-profile 12. Furthermore, other combinations of profiles are also possible. Figures 4A and 4B show a further embodiment of the panel element 100 in a three-dimensional overall view in Figure 4A and in a three-dimensional detailed view in Figure 4B, in which a plate 2 is mounted on the profile frame 1, for example by screwing or riveting, and which may be, for example, a metal plate, a plastic plate or, preferably, a perforated sheet. In particular, as can be seen in Figure 4B, the plate 2 may abut against the first leg part 23 of each of the vertical frame elements 20. Furthermore, the plate 2 may preferably be fastened to the first leg part 23 of each of the vertical frame elements 20, for example by riveting or screwing. Alternatively or additionally, the plate 2 may also be fastened to the horizontal frame elements 10. Figures 5A to 5C show, in a three-dimensional view and in two associated detailed views, a composite panel 200 comprising two panel elements 100 that are connected to one another by two connectors 30. In the illustrated embodiment, the panel elements 100 have horizontal frame elements 10 as described in connection with Figures 3A and 3B. In particular, Figures 5A and 5B show the composite panel 200 in a state during assembly in which the connectors 30 have already been inserted into the horizontal frame elements 10 of a first panel element 100 and are fixed in place by retaining elements 102 in the form of bolts and secured by spring retainers 103, as can be seen in Figures 5A and 5B. The second panel element 100 is shown at the moment just before it is slid onto the two connectors 30, i.e., just before the connectors 30 are inserted into the horizontal frame elements 10 of the second panel element 100, as indicated by the sliding direction 94 in Figure 5A. The connectors 30 enable a coplanar arrangement of the panel elements. By means of conically formed retaining elements 102, such as conical pins, a pulling motion of the panel elements 100 with the recesses 19 towards the stop elements 330 of the connectors 30 can be achieved when inserted into the fastening openings of the connectors 30 and into the mounting holes 18 of the horizontal frame elements 10 of the profile frame 1 of the panel elements 100. The shape of the stop elements 330 of the connectors 30, together with the correspondingly shaped recesses 19 in the profile frame 1 of the panel elements 100, enables a positive fit without play after assembly. The composite panel 200 can be extended accordingly using additional connectors 30, which are already shown mounted on the second panel element 100 in Figure 5A, and additional panel elements 100. As can be seen in Figure 5C, after the panel elements 100 are joined together by the connectors 30, the first leg parts 23 of the directly adjacent vertical frame elements 20 of the two panel elements 100 abut directly against one another, so that the preferred edge profile design of the vertical frame elements 20 shown allows for a seamless connection of the panel elements 100 to one another. The adjacent vertical frame parts 22 of the two panel elements 100, on the other hand, are spaced apart from one another because they are set back relative to the horizontal end regions 15 of the horizontal frame elements 10, which is advantageous in connection with the following embodiments. Figure 6A shows, in a detailed view, a panel element 100 according to a further embodiment, which additionally comprises a folding platform 5 that is attached to the profile frame 1 and comprises two foldable bracket elements 50 and a base element 59 attached to the bracket elements 50. Figure 6B shows a detail thereof without the base element 59 installed, for better understanding. The following description refers equally to Figures 6A and 6B. One of the hinged bracket elements 50 is attached to each of the two vertical frame elements 20. In a particularly preferred embodiment, each of the bracket elements 50 can be attached to the vertical frame part 22 of a vertical frame element 20 by means of a retaining element 102, such as a bolt described in connection with the previous embodiment. For this purpose, each of the bracket elements 50 includes a hinge element 51 that is pivotally secured by means of a retaining element 102 in a mounting hole 28 of the vertical frame part 22 of one of the vertical frame elements 20. To this end, the hinge elements 51 comprise hinge openings 57 for the retaining elements 102. This allows for easy assembly and disassembly, as well as flexible height adjustment independent of other panel elements within a composite panel. The retaining elements 102 thus form vertical pivot points in the hinge openings 57 and the mounting holes 28, which simultaneously serve to secure the elements to the vertical frame elements 20. Each of the hinge elements 51 may, in particular, comprise two hinge plates 52 with the hinge openings 57, which together partially encompass the respective vertical frame element 20. In particular, this may mean that the vertical frame part 22 of a vertical frame element 20 is arranged in the horizontal direction 91 between the two hinge plates 52 of a bracket element 50. Furthermore, each of the bracket elements 50 includes a support element 53 in the form of a cantilever with a bearing surface 54 on which the base element 59 is positioned. For example, the base element 59, which may be constructed in one or more parts and may, for example, comprise one or more panels made of or consisting of wood and / or plastic, may be screwed, riveted or bolted to the bearing surfaces 54. Furthermore, each of the bracket elements 50 has a support surface 55, which may, for example, be formed as part of the support element 53 and which, in the unfolded position of the folding platform 5 shown in Figures 6A and 6B, rests against the vertical frame element 20. In the illustrated configuration, the support surfaces 55 of the bracket elements 50 each rest against the second leg part 24 of a vertical frame element 20. This allows the folding platform 5, when in the unfolded state, to be supported by the vertical frame elements 20 and, in the shown embodiment, specifically by the second leg parts 24 of the vertical frame elements 20. As can be seen in Figure 6B, the hinge plates 52 are firmly connected to the support element 53 via a connection region 56, wherein, for each of the bracket elements 50, the connection region 56 is arranged as extensions of the hinge plates 52 between the hinge element 51 and the support element 53, in contact with the bearing surface 54. In addition, the base element 59 may have slot-shaped openings 591, through which the base element 59 is slid onto the connection regions 56 of the bracket elements 50. As a result, the base element 59 can protrude, along the horizontal direction 91, beyond the hinge elements 51 and, in particular, can terminate flush with the horizontal frame elements 10 and with the first leg parts 23 of the vertical frame elements 20 in the horizontal direction 91. In a folded-up position, the folding platform 5 can be temporarily secured. For this purpose, the hinge elements 51 may have locking openings 58 in the hinge plates 52, through which the hinge elements 51, and thus the folding platform 5, can be secured in the folded-up position using additional retaining elements 102 in mounting holes 28 of the vertical frame elements 20. For example, the base element can also be temporarily secured in a folded-up position by a rope attached, for instance, to a horizontal frame element 10. Furthermore, a clamping mechanism may also be provided. As an alternative to the shown embodiment, as illustrated in a partial view of a further embodiment in Figure 6C corresponding to Figure 6B, the hinge elements 51 of the bracket elements 50 may be embodied to be firmly connected to a securing element 102. In particular, the hinge element 51 of each of the bracket elements 50 may comprise exactly one hinge plate 52 that is firmly connected to a retaining element 102, for example by welding or as a one-piece construction. Most preferably, the retaining elements 102 of the hinge elements 51 of the two bracket elements 50 point in the same direction, so that the folding platform 5 can be hooked into the vertical frame elements 20 from a side, i.e., into mounting holes 28 of the vertical frame parts 22 of the vertical frame elements 20, and can be rotatably mounted and secured by fasteners such as spring retainers or nuts. In other words, the retaining elements 102 in the hinge plates 52, similar to the hinges of a door, can be inserted from one side into the mounting holes 28 of the vertical frame elements 20 and secured on the other side. Figures 7A and 7B show, in views corresponding to Figures 6A and 6B, parts of a composite panel 200 comprising two panel elements 100 according to the previous embodiment. In the composite panel 200, the at least two panel elements 100 are connected to one another in the horizontal direction so that they are directly adjacent to one another, as described in conjunction with Figures 5A to 5C. Because the vertical frame parts 22 of the vertical frame elements 20 are set back from the ends of the horizontal frame elements 10 along the horizontal direction 91, as described above, it is possible to attach folding platforms 5 side-by-side directly to the vertical frame elements 20 of the adjacent panel elements 100 using the hinge elements 51. Due to the previously described design of the folding platforms 5, they can be attached directly adjacent to one another without adversely affecting each other. Figures 8A to 8C show, in a three-dimensional overall view, a detailed view and an exploded view, a further embodiment of a panel element 100, in which an insert element 3, which may also be referred to as an inlay, is attached to the profile frame 1 in addition to a folding platform 5, with which desired visual and / or protective effects, as described above in the general part, can be achieved. The insert element 3 may preferably be secured with at least one cross strut 4 and, more preferably, with multiple cross struts 4 arranged at a distance from one another in the vertical direction 92. In particular, the insert element 3 may be arranged in the profile frame 1 between the at least one cross strut 4 and the panel 2. As described above, the vertical frame part 22 of the vertical frame elements 20 has fastening openings 29 for the cross struts 4. The insert element 3 may, in a particularly preferred embodiment, abut the vertical frame part 22 of each of the vertical frame elements 20 and the facing surfaces 14 of the horizontal frame elements 10, thereby covering the rectangular area enclosed by the horizontal frame elements 10 and the vertical frame elements 20. The installation of insert elements 3 into panel elements 100 of a composite panel is possible with minimal effort, since the cross struts 4 used as fastening bars do not intersect between adjacent panel elements. As an alternative to the shown embodiment, the insert element 3 can also be secured by means of longitudinal struts that are attached to the horizontal frame elements 10. Figure 9A shows, in a three-dimensional overall view, an enclosure 1000 for a scaffolding system with an assembly system 990 of several composite panels 200 arranged one above the other and connected to one another, which may comprise panel elements 100 as described in conjunction with Figures 2A to 7B and which are attached to vertical supports 900 of the enclosure 1000. In Figure 9A, all folding platforms of the panel elements 100 are shown in the unfolded position. Figure 9B shows a detail of one of the composite panels 200 of the assembly system 990 of the enclosure 1000, in which, by way of example only, a folding platform 5 is in the folded-up state. For clarity, only one panel element is labeled in Figure 9A. The enclosure 1000 can be attached to a scaffolding system and serve, for example, as an access point, a walking surface and / or a protective system and / or a safety system for construction work. Among other things, the panel elements 100 allow for a simple, articulated and stable attachment of the bracket elements of the folding platforms 5, which are suitable for supporting loads when unfolded. In particular, as described in connection with Figures 6A to 7B, cantilever elements, and thus folding platforms 5, can be mounted directly next to one another on adjacent panel elements 100 within a composite panel 200, so that the folding platforms 5 can form an integrated system with the profile frames 1 of the panel elements 100 without requiring additional components, such as adapters or extra vertical struts, and without any additional effort. Furthermore, a locking mechanism for folded-up folding platforms 5, as described above, may be provided, which can be advantageous for transport and during evasive maneuvers as construction progresses, for example, during vertical climbing movements of the scaffolding system. When transporting a composite panel 200, it may be advantageous to use connectors to join at least some of the panel elements 100, which allow the panel elements 100 to rotate relative to one another and thus enable panel elements 100 to be folded onto other panel elements 100. In a particularly preferred embodiment, panel elements 100 with folded-up folding platforms 5 can be folded one on top of the other using suitable connectors in the form of hinges, so that a composite panel 200, and in particular an assembly system 990 of multiple composite panels 200, can be adjusted, for example, to a required transport width. In other words, in order to comply with the transport width on a truck, for example, at least one additional foldable panel element 100 with attached hinges can be used in each composite panel 200 of an assembly system 990. For example, to transport the assembly system 990 of the enclosure 1000 shown in Figure 9A, having five composite panels 200 arranged one above the other and fastened together, the composite panels 200 may be embodied such that hinged connectors are used between the respective outer pairs of panel elements along the horizontal direction 91, so that the respective outer panel elements 100 can be folded. Figures 10A and 10B show, in a three-dimensional view and a side view, several assembly systems 990 that are configured like the assembly system 990 shown in Figure 9A and in which the outer panel elements are each folded as described above. The assembly systems 990 folded in this manner can be stacked on top of one another using transport carriers 99 and thus transported, for example, on a truck. This enables compact, space-saving stacking of the assembly systems 990 with their folding platforms already installed and folded-up. As indicated by the arrows in Figures 10A and 10B, each of the folded assembly systems 990 can be lifted directly from the stack. Subsequently, the assembly systems 990 can be unfolded to the working width shown in Figure 9A either before or, preferably, after installation on the building, i.e., in particular after integration into the enclosure 1000 by mounting them on the vertical supports 900. In other words, the folded-up panel elements of the composite panels 200 can be unfolded again either before or after installation on the building. It is particularly preferred that the panel elements 100 and subsequently also the folding platforms 5, while suspended from the building, be unfolded to the full size of the composite panels 200 and thus of the assembly system 990. As described, the panel elements described here make it possible to fully assemble a composite panel, and, furthermore, an assembly system, on the ground and, in particular, at the factory, since the composite panel or assembly system, once delivered to a construction site in a fully assembled state, merely needs to be unfolded, without the need to install any additional components of the composite panel or the assembly system after assembly and integration into the enclosure for the scaffolding system. Any composite panel folded due to the limited transport width of trucks can be lifted by a crane and suspended from the building or the scaffolding system by integrating it into the enclosure. Thus, neither a temporary storage area, which is scarce, especially in inner-city areas, nor a crane lift for pre-assembly work at the construction site is necessary. The panel element described here thus allows for simple and cost-effective manufacturing as well as easy handling. Furthermore, the panel element allows for quick assembly and is robust. In particular, panel elements for a composite panel can be systematically manufactured and delivered preassembled both as a composite panel and as part of an assembly system, which is advantageous from a logistical standpoint. The features and embodiments described in connection with the figures may be combined with one another in accordance with further embodiments, even if not all combinations are explicitly described. Furthermore, the embodiments described in connection with the figures may alternatively or additionally include further features as described in the general part. The invention is not limited to the description based on the embodiments.
