[0002] CONNECTOR, PANEL COMPOSITION WITH CONNECTOR AND SCAFFOLDING SYSTEM

[0003] A connector for connecting panel elements for a scaffolding system, a panel assembly with at least two panel elements and a scaffolding system with a panel assembly are specified.

[0004] So-called enclosure panels are known for scaffolding systems. These are attached, for example, to the outside of a scaffold, a climbing formwork or a building under construction or restoration to enclose the scaffold or the building under construction or restoration. They can serve for safety as well as as a visual barrier and / or protection against environmental influences such as wind and solar radiation. Such enclosure panels are usually installed with screws or clamps, which however require tools. Furthermore, the installation of such panels is often complicated and time-consuming and a wide product range is necessary to meet the diverse installation-specific requirements. A simplified assembly system for such panels is therefore desirable.

[0005] At least one object of certain embodiments is to provide a connector for connecting two panel elements for a scaffolding system. Further objects of certain embodiments are to provide a panel assembly with at least two panel elements and a scaffolding system with a panel assembly. These objects are achieved by subject matter according to the independent patent claims. Advantageous embodiments and developments of the subject matter are characterized in the dependent claims and will further emerge from the following description and the drawings.

[0006] According to at least one embodiment, a connector for connecting two panel elements for a scaffolding system is specified. According to at least one further embodiment, a panel assembly with at least two panel elements and at least one connector is specified. In particular, the connector can be provided and configured to mechanically and firmly connect two panel elements to one another. According to at least one further embodiment, a scaffolding system with at least one panel assembly is specified. The following description refers equally to the connector, the panel assembly with the connector, and the scaffolding system with the panel assembly.

[0007] In a preferred embodiment, a connector for connecting panel elements for a scaffolding system has the following features:

[0008] - a base plate with a fixing area and a first insertion area, wherein an arrangement direction from the fixing area to the first insertion area defines a first insertion direction of the connector for insertion into a frame element of one of the panel elements,

[0009] - a first fastening opening for a first securing element,

[0010] - at least one first stop element in the fixing region on a first main surface of the base plate, wherein the first insertion region and a first part of the fixing region, together with a part of the first stop element, form a first connection region for one of the panel elements. Furthermore, the connector can alternatively or additionally have features as described below.

[0011] The scaffolding system can, for example, comprise a formwork system. Formwork systems for erecting buildings are used to produce building components, such as walls or ceilings, and are generally designed to create a filling space for a hardenable building material, such as a concrete material. The building material can be poured into the filling space and, once it has hardened, form the desired building component. Alternatively or additionally, the scaffolding system can have or be a climbing system. Climbing systems are devices designed to climb up building walls, for example to carry out renovation or cleaning work, or, in particular, in building construction, to erect the building walls up which the climbing system climbs.For example, in building construction, wall sections are erected in sections. After curing, the climbing system can climb up them to continue erecting the building. In particular, the scaffolding system can preferably include or be a formwork system and a climbing system.

[0012] The at least one panel assembly with the at least two panel elements can, for example, be mounted on an exterior side as viewed from the building to serve as a safety system, in particular as a fall protection device, for persons on the scaffolding system. Furthermore, the at least one panel assembly can also serve as a privacy screen and / or weather protection, for example as sun and / or wind protection. Furthermore, the at least one panel assembly can also serve, for example, as an advertising space on the scaffolding system.

[0013] Each of the panel elements of the panel assembly can have a profile frame. The profile frame can particularly preferably have a rectangular shape. A covering plate, for example a metal plate, a plastic plate or a perforated sheet, can be attached to the profile frame. Furthermore, an insert element can be attached to the profile frame, with which desired optical effects and / or protective effects can be achieved. The profile frame can be formed from several frame elements, particularly preferably from two horizontal frame elements and two vertical frame elements which are connected to one another to form a rectangular shape. Terms such as "horizontal" and "vertical" can here and hereinafter, unless otherwise stated, particularly preferably refer to an orientation during normal installation of the panel elements in the panel assembly and in the scaffolding system.

[0014] Each of the frame elements can be a profile element, which 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 identical or different profile types mentioned. In particular, the frame elements can be provided with mounting holes designed and configured to receive securing elements.

[0015] Here and below, a securing element can in particular be selected from bolts, screws, rivets and pins. In particular, the scaffolding system can have at least one support which is fastened, for example, to a building or part of a building. For example, the support can be a vertical support. The at least one panel assembly can be fastened directly or indirectly to the support, for example via one or more struts. These can, for example, be screwed or bolted struts which can, for example, be fastened directly to a profile frame of a panel element and to a support of the scaffolding system.

[0016] By means of at least one plug connector, two panel elements which are directly adjacent to one another in a panel assembly can be mechanically connected to one another and thus fixed to one another. Particularly preferably, two panel elements are connected to one another using two identically designed plug connectors. The plug connector described here can in particular have a first connection area for the mechanical connection of the plug connector to a first of two panel elements and a second connection area for the mechanical connection of the plug connector to a second of the two panel elements. A mechanical connection can in particular mean a form-fitting connection or a force-fitting connection or a form-fitting and force-fitting connection. Particularly preferably, the connection can be released by removing the plug connector(s), so that the panel assembly can be disassembled again into individual panel elements.

[0017] The connector can, in particular, comprise or be made of a metal, preferably steel. Particularly preferably, all parts and regions of the connector described below can comprise a metal and, in particular, can be made of or with steel and / or aluminum. A combination of different parts made of different materials is also possible.

[0018] According to a further embodiment, the plug connector has a base plate. The base plate can in particular have a first main surface and a second main surface opposite the first main surface, which are connected to one another by one or more side surfaces. In particular, the base plate can be flat, so that the first and second main surfaces are parallel to one another and have a height that is smaller than a length and a width. The height can in particular be defined as the distance between the first and second main surfaces, while the length and width are two mutually perpendicular dimensions, both of which are in turn perpendicular to the height. Thus, the length and width can lie parallel to the first and second main surfaces. The length can preferably be the greatest extent of the base plate along the first and second main surfaces.Lengths, widths and heights of other parts of the connector can be dimensions in corresponding directions.

[0019] According to a further embodiment, the first and / or second main surfaces of the base plate can be curved. A combination of a curved and a flat main surface is also possible. Furthermore, the base plate can have a plurality of plate elements stacked one above the other. The base plate can therefore have a plurality of plate elements which are arranged one above the other in the height direction, i.e. in particular in a direction perpendicular to the first main surface, so that the plate elements can be spaced apart from one another along the height direction. The plurality of plate elements can be connected to one another, for example, via one or more plate connecting elements. In the case of a plurality of plate elements which can form the base plate, the plug connector has an uppermost and a lowermost plate element along the height direction.In this case, the first main surface can be the main surface of the uppermost plate element facing away from the lowermost plate element along the height direction. The second main surface can correspondingly be the main surface of the lowermost plate element facing away from the uppermost plate element along the height direction.

[0020] According to a further embodiment, the base plate has a fixing region. In particular, a first stop element can be formed in the fixing region, which is provided and configured to be pressed with at least one surface against a part of a frame element of the at least one panel element when mounted on at least one panel element. The first stop element can particularly preferably be formed on the first main surface of the base plate.

[0021] According to a further embodiment, the base plate has a first insertion region. At least the first insertion region or the first insertion region and a part of the fixing region can be provided and designed to be inserted into a frame element of a panel element and to be further fixed there. The first insertion region can in particular be the region with which the plug connector is inserted into the frame element and then pushed further until preferably a part of the fixing region has also been pushed in. The arrangement direction from the fixing region to the first insertion region defines a first insertion direction of the plug connector for insertion into a frame element of a panel element. In particular, the length described above can particularly preferably be dimensioned along the first insertion direction, while the width and height can each be perpendicular to the first insertion direction.In particular, the first insertion region and a first part of the fixing region with a part of the first stop element can form a first connecting region for a panel element, into the frame element of which the first insertion region is inserted.

[0022] According to a further embodiment, the base plate has a first fastening opening for a securing element. Particularly preferably, the first fastening opening can be formed in the first insertion region. In particular, after the first insertion region or the first insertion region and a part of the fixing region have been pushed into the frame element of a profile frame of a panel element, the first fastening opening can overlap with at least one mounting hole in the frame element, so that a securing element can be pushed through the at least one mounting hole and the first fastening opening. The connector can thereby be mechanically fastened to a panel element.Particularly preferably, the region of the frame element into which the plug connector is inserted with the first insertion region or the first insertion region and a part of the fixing region preferably has two plate-shaped regions provided with mounting holes, between which at least a part of the first connecting region is arranged during insertion. The securing element can preferably be pushed first through one of the mounting holes of one of the two plate-shaped regions, then through the first fastening opening of the plug connector and then through one of the mounting holes of the other of the two plate-shaped regions of the frame element.

[0023] According to a further embodiment, the first insertion region tapers in the direction away from the fixing region. The first insertion region therefore preferably has a decreasing width in a direction along the insertion direction away from the fixing region, wherein, as described above, the width is preferably measured in a direction perpendicular to the insertion direction and perpendicular to a normal of the first main surface. The first insertion region can therefore be conical in terms of width and preferably have two insertion bevels which are formed by side surfaces of the base plate. Particularly preferably, the first insertion region can be symmetrical in relation to a plane of symmetry perpendicular to the width direction. Furthermore, the first connecting region or else the base plate can be correspondingly symmetrical.

[0024] The first stop element can protrude from the base plate, in particular from the first main surface of the base plate. Particularly preferably, the first stop element does not protrude beyond the base plate in the width direction, but rather extends away from the first main surface with a main extension direction in the height direction. The stop element can therefore have a smaller width than the base plate is wide.

[0025] The first stop element can be formed integrally with the base plate. Furthermore, the first stop element can be attached to the base plate, for example by welding, clamping, or screwing.

[0026] According to a further embodiment, the first stop element has a cylindrical shape, a truncated pyramid shape, or a truncated cone shape. In particular, the first stop element can have a cross-section that is round or polygonal or a combination thereof when viewed towards the first main surface. In particular, the cross-section can relate to a base area of ​​the first stop element, wherein the base area can be referred to as the surface of the first stop element that borders the first main surface. If the base plate and the first stop element are formed in one piece, the base area can be an imaginary surface that lies in the plane formed by the first main surface.Opposite the base surface, the first stop element has an upper side surface which faces away from the first main surface and with which the first stop element ends in a direction facing away from the first main surface. The base surface and the upper side surface particularly preferably have the same shape. The distance of the base surface and thus the first main surface from the upper side surface defines the height of the first stop element. The first stop element particularly preferably has a base surface in the shape of a hexagon, a rectangle or a rhombus. The upper side surface is preferably designed with the same shape as the base surface. In addition, other shapes are also possible for the base surface and the upper side surface, such as an octagon, an ellipse, a circle, a triangle and combinations of the aforementioned shapes.The base surface and the upper side surface are connected to one another by a circumferential, curved side surface or by a plurality of side surfaces connected by edges, which can also be referred to as jacket surfaces. Parts of the one or more side surfaces of the first stop element are provided and designed to be pressed against a recess in the profile frame, in particular in a frame element, of a panel element when the plug-in connector is fastened to the frame element as described above with the securing element inserted through the first fastening opening. Particularly preferably, the first stop element is provided and designed to engage in a form-fitting manner with part of the side surface(s) in a recess in a wall of a frame element of a panel element. This part of the side surface(s) thus forms part of the first connection region.

[0027] According to a further embodiment, a second stop element is formed on the second main surface of the base plate opposite the first main surface in the fixing region, wherein the first connecting region has a first part of the second stop element. All features and properties for the first stop element can preferably also apply to the second stop element. Particularly preferably, the first and second stop elements are of identical design. This can mean, in particular, that the first and second stop elements have a substantially identical outer contour. Alternatively, the first and second stop elements can be of different design.

[0028] According to a further embodiment, a first positioning element in the form of an elevation is formed on the base plate on the first main surface between the first stop element and the first fastening opening. The first positioning element can in particular be an elevation, for example a fin, which extends over part of the first main surface. The first positioning element can be fastened to the first main surface, for example by welding or clamping, or preferably can be formed integrally with the base plate. The first positioning element can have a main direction of extension in the longitudinal direction, i.e. along the first insertion direction, or in the transverse direction, i.e. perpendicular to the first insertion direction, and can also extend, for example, over the entire width of the base plate.Particularly preferably, the first positioning element has a main extension direction along the first insertion direction and thus extends longitudinally along the first insertion direction. Furthermore, the first positioning element can have an insertion bevel facing away from the first stop element. Thus, the insertion bevel can be formed along the first insertion direction at the front of the first positioning element, which is preferably designed as a fin. The first positioning element can preferably be arranged partially in the fixing region and partially in the first insertion region.

[0029] According to a further embodiment, a second positioning element in the form of an elevation is formed on the second main surface of the base plate, opposite the first main surface. All features and properties for the first positioning element can preferably also apply to the second positioning element. Particularly preferably, the first and second positioning elements are of identical design. This can mean, in particular, that the first and second positioning elements have a substantially identical outer contour. Alternatively, the first and second positioning elements can be of different design.

[0030] The base plate, the first positioning element and the second positioning element can together have a height that is adapted to the profile of the frame element of the panel element into which the first connecting region is inserted. This can mean in particular that the first and second positioning elements each have a surface facing away from the base plate, which surface can bear tightly against the frame element in the inserted state or can also preferably have some play, for example to make insertion easier. The fixing region can have a width that is adapted to the profile of the frame element of the panel element into which the first connecting region is inserted.In the inserted state, the fixing region can thus bear tightly against the frame element with regions of the circumferential side surface which connect the first and second main surfaces to one another, or can also preferably have some play, for example to facilitate insertion. While the fixing region can therefore be provided and designed to bring about lateral guidance of the plug-in connector in the frame element, the positioning elements can be provided and designed to bring about vertical guidance. According to a further embodiment, the fixing region and the first insertion region are designed symmetrically with respect to a plane of symmetry parallel to the first main surface. In other words, with respect to the height direction, a top side and a bottom side of the plug-in connector can be designed identically at least in the fixing region and in the first insertion region.Particularly preferably, the entire connector can be designed symmetrically with respect to the plane of symmetry parallel to the first main surface. This can facilitate assembly of the connector.

[0031] According to a further embodiment, the plug connector has a second connection region for a further panel element, which has a second insertion region and a second part of the fixing region with a second part of the first stop element, wherein the fixing region is arranged between the first and second insertion regions. The second connection region can have a second fastening opening for a further securing element. Furthermore, an arrangement direction from the fixing region to the second insertion region can define a second insertion direction of the plug connector for insertion into a frame element of the further panel element. Accordingly, both connection regions of the plug connector can each be designed for insertion into a frame element of a respective panel element.The first and second insertion directions can preferably be anti-parallel, so that the two panel elements can be pushed onto the plug connector in direct extension of one another and can be fixed to one another by the latter. The second connection region can have features and properties that are described in connection with the first connection region. The first connection region and the second connection region can preferably be of identical design. This can mean in particular that the first connection region and the second connection region can preferably be of substantially symmetrical design to the fixing region. In particular, the second insertion region can be of identical design to the first insertion region. Furthermore, the first part of the fixing region of the first connection region can be of identical design to the second part of the fixing region of the second connection region.Particularly preferably, the connector is designed to be symmetrical with respect to a plane of symmetry perpendicular to the first and second insertion direction.

[0032] According to a further embodiment, the plug connector has a second connection region for a further panel element, wherein the second connection region has a first plate element and a second plate element, which are spaced apart from one another in a direction perpendicular to the first main surface and which are provided and configured to partially encompass a part of a profile frame of the further panel element. In particular, a part of a frame element, in particular a horizontal frame element, of the further panel element, to which the plug connector is fastened with the second connection region, can be encompassed.While in this embodiment the first connecting region is designed for insertion into a frame element of a profile frame of a first panel element, the second connecting region is provided and designed for mounting externally on the frame element of a profile frame of a second panel element.

[0033] According to a further embodiment, the first and second plate elements each have at least two second fastening openings, each for a securing element, so that each of the securing elements can be pushed through a second fastening opening in the first plate element and a second fastening opening in the second plate element. The second fastening openings thus overlap in pairs when viewed from above along the height direction. In the assembled state of the connector, at least one mounting hole in the frame element of the further panel element is arranged between the second fastening openings, through which a common securing element is pushed, and through which the securing element is also pushed.

[0034] An arrangement direction of the at least two second fastening openings of the first panel element and the at least two second fastening openings of the second panel element can enclose an angle of greater than or equal to 0° and less than or equal to 180° with the first insertion direction. This allows an angle to be defined at which the two interconnected panel elements are positioned relative to one another. The arrangement direction and the first insertion direction are preferably perpendicular or parallel to one another.

[0035] For example, the first plate element can be fixed to the first stop element, and the second plate element can be fixed to the second stop element. Alternatively, it may also be possible for the first plate element and the second plate element to be part of a U-profile that is fixed to the base plate. "Fixed" in this context can particularly mean permanently fixed, for example, integrally formed, clamped, or welded.

[0036] According to a further embodiment, the base plate is T-shaped and has a second connecting region for a further panel element. In particular, in this embodiment, the second connecting region can be formed by a part of the base plate. In particular, the second connecting region can be provided and designed to be mounted on the further panel element on a receiving element provided and designed for this purpose, for example mounting tabs with mounting holes, between which the base plate can be arranged. The second connecting region can have at least one second fastening opening for a further securing element. The further securing element can be rotatably mounted in the fastening opening.In particular, the second connection region can be provided and configured to be partially arranged between mounting tabs of the further panel element and to be rotatably fastened by means of the further securing element. Furthermore, the second connection region can also have a second fastening opening for yet another securing element, with which the second connection region can be fixed to the further panel element such that the connector is no longer rotatable.

[0037] The two second fastening openings can preferably have an arrangement direction that is perpendicular to the first insertion direction. This can mean that the at least one fastening opening of the first connecting region and the two second fastening openings of the second connecting region are located at the corners of an imaginary triangle.

[0038] Furthermore, instead of one of the second fastening openings, a locking element can be provided in the second connection area, which can be connected to another locking element on the further panel element. Furthermore, it is also possible that no second fastening opening is present. In this case, the further panel element can be held at a different location relative to the first panel element.

[0039] To form a panel assembly, the plug connector, as described above, is inserted with the first connection region, i.e. with the first insertion region and preferably a part of the fixing region, into a frame element of a profile frame of a first of at least two panel elements of the panel assembly to be formed. Furthermore, the plug connector is fastened to the first of the at least two panel elements by means of at least one first securing element and to a second of the at least two panel elements by means of at least one second securing element. Accordingly, the first connection region is fastened and secured to the first panel element and the second connection region is fastened and secured to the second panel element each with at least one securing element. The two panel elements are particularly preferably connected to one another by two plug connectors. Two panel elements can preferably also be connected with three or more plug connectors.The connectors can be of identical design. As described above, the securing elements used with the connector are preferably pin-shaped, such as bolts or screws. Particularly preferably, each of the securing elements has at least one conical end region, which facilitates insertion into a mounting opening and a fastening opening. Furthermore, a spring lock or a nut can be provided to secure each of the securing elements.

[0040] The panel assembly may comprise more than two panel elements, with two immediately adjacent panel elements of the panel assembly being connected by at least one connector. Different connectors can be used in accordance with the previously described embodiments.

[0041] The connector described here can, according to the described embodiments, allow a wide variety of uses for straight, angled, movable, split and / or foldable panel element arrangements. For example, in a design as a corner connector, it is possible to arrange panel elements at an angle of 90° or another angle to one another. Regardless of the specific embodiment, the connector described here preferably allows a completely play-free panel element connection and force transmission. This advantageously results in the avoidance of movement and rattling noises in the panel assembly. Furthermore, simple assembly with only two or three securing elements such as bolts is possible instead of four or more fasteners in prior art solutions. A flat panel element arrangement is possible, which can be advantageous for advertising purposes, for example.Furthermore, no additional diagonal bracing is required for stiffening, as the panel elements are connected to each other by a form-fitting connection.

[0042] The connector described here can be used independently of the specific design according to the described

[0043] Design forms allow a force-fitting, form-fitting, play-free, centering locking and connection of panel elements to form a panel assembly, which can be used in a scaffolding system, for example, as so-called perimeter protection, protection screen, enclosure and / or protective wall such as a climbing protection wall.As described, the plug connector can particularly preferably be inserted with at least one side into a profile frame of a panel element and have a one-part or multi-part base plate on which at least one stop element is arranged substantially perpendicular to the main surfaces, which stop element strikes and engages in a centering, form-fitting manner on an end region of a frame element, and which has at least one fastening opening in order to insert a securing element through the frame element and the plug connector, so that in interaction with the stop element bending moments can be transferred from the plug connector to the profile frame.

[0044] Further advantages, advantageous embodiments and further developments emerge from the exemplary embodiments described below in conjunction with the figures.

[0058] Figure 1 shows a schematic representation of a panel assembly 200 according to one exemplary embodiment. The panel assembly 200 can in particular be part of a scaffolding system which is explained further below in connection with some exemplary embodiments. In particular, the panel assembly 200 has at least two panel elements 100 which can be connected to one another by means of at least one plug-in connector 30. For the sake of clarity, Figure 1 shows the panel elements 100 and the plug-in connector 30 in a state in which they are not yet mechanically connected to one another, the operative connection between the panel elements 100 and the plug-in connector 30 being indicated by the double arrows.

[0059] Each of the panel elements 100 has a profile frame 1, as described in detail below. The profile frame 1 of each of the panel elements 100 can preferably have a rectangular shape and be formed from a plurality of frame elements, particularly 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" refer here and below, unless otherwise stated, to the installation of the panel elements 100 in the panel assembly 200 and in the scaffolding system as intended. Accordingly, in some figures the horizontal direction 91 and the vertical direction 92 are indicated in order to indicate an orientation of the panel elements as intended.In addition, in some figures, such as in figures 2A to 5 and in further figures, a depth direction 93 may be indicated, which is perpendicular to the horizontal direction 91 and perpendicular to the vertical direction 92. The plug connector 30 has, in particular, a first connection region 31 for mechanically connecting the plug connector 30 to a first of the two panel elements 100 and a second connection region 32 for mechanically connecting the plug connector 30 to a second of the two panel elements 10. A mechanical connection can, in particular, mean a positive-locking and a non-positive connection.

[0060] Figures 2A to 2D show schematic representations of different views of a panel element 100 according to an exemplary embodiment. Figure 2A shows a three-dimensional view of the panel element 100. Figures 2B, 2C, and 2D show cutaway views of parts of the panel element 100. The following description refers equally to Figures 2A to 2D.

[0061] The panel element 100 has, as described above, a profile frame 1 which is formed by two horizontal frame elements 10 and two vertical frame elements 20. Each of the horizontal frame elements 10 has a main extension direction which runs along the horizontal direction 91. Each of the vertical frame elements 20 has a main extension direction which runs along the vertical direction 92. Perpendicular to the horizontal and vertical directions 91, 92, as described above, a depth direction 93 is defined. The vertical frame elements 20 are arranged along the vertical direction 92 between the horizontal frame elements 10 and have vertical end regions 25 which are connected to the horizontal frame elements 10. For example, the frame elements can be permanently connected to one another by welding, riveting or screwing or a combination thereof.A plate 2, which can be formed by a perforated sheet, for example, can be mounted on the profile frame 1, for example by screwing or riveting.

[0062] Each of the frame elements, i.e., the horizontal frame elements 10 and the vertical frame elements 20, is preferably a profile element, which 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 identical or different profile types. In the illustrated embodiment, the horizontal frame elements 10, as shown in detail in Figures 2C and 2D, are designed as hollow profiles, in particular as square profiles 11. The vertical frame elements 20 are, as shown in detail in Figure 2B, designed as Z-profiles 21, each having a central part 22, to which a first leg part 23 and a second leg part 24 are adjacent at an angle on the sides lying opposite one another along the depth direction 93, said first leg part 23 and second leg part 24 extending in opposite directions along the horizontal direction 91.

[0063] The frame elements, i.e. the horizontal frame elements 10 and the vertical frame elements 20, are provided with mounting holes 18, of which for the sake of clarity only a few are provided with reference symbols and which are intended and configured to receive securing elements. Here and below, a securing element can in particular be selected from a bolt, a screw, a rivet and a pin. Purely by way of example, in the exemplary embodiments described below, the securing elements are designed as bolts. The vertical frame elements 20 additionally have fastening openings 29 into which cross struts 4 can engage in order to fasten an insert element 3 in the profile frame 1 on the plate 2, as shown in conjunction with Figures 4A and 4B.

[0064] As can be seen in Figures 2C and 2D, the horizontal frame elements 10 have horizontal end regions 15 in which recesses 19 are formed, which are intended and configured to allow parts of stop elements of plug-in connectors to engage, as described further below.

[0065] As shown in Figures 3A and 3B, which correspond to the views of Figures 2C and 2D, using a further exemplary embodiment, the horizontal frame elements 10 can, for example, also comprise a combination of a square profile 11 with an L-profile 12. Other combinations of profiles are also possible.

[0066] 4A and 4B show an exploded view and in a finished state of a panel element 100 which has a profile frame 1 with a plate 2 mounted thereon, as described in connection with Figures 2A to 3B. An insert element 3, for example a corrugated plate with or made of plastic as a privacy and / or wind screen, is fastened in the profile frame 1 by means of cross braces 4. Furthermore, the panel element 100 has, purely by way of example, a folding platform 5 which is fastened to the profile frame 1 and in particular to the vertical frame elements of the profile frame 1 by means of securing elements such as bolts. The folding platform 5 can be fastened to the profile frame 1 in a folded-up manner for mounting the panel element 100 in a panel assembly and further in a scaffolding system, and can be folded out after mounting if required.

[0067] Figure 5 shows a schematic representation of a section of an exemplary embodiment of a scaffolding system 1000 with at least one panel assembly 200 with panel elements 100 which are designed as described in connection with Figures 4A and 4B. Purely by way of example, a folding platform 5 on one of the panel elements 100 is folded in, while the folding platforms 5 on two further panel elements 100 are shown unfolded. The scaffolding system 1000 can, for example, have or be a formwork system and a climbing system, as described in the general part. The panel assembly 200 is mounted, for example, by struts on supports, in particular on vertical supports 900, of the scaffolding system 1000. These can be, for example, screwed or bolted struts, which can be attached directly to a profile frame 1 of one or more panel elements 100 of the panel assembly 200.The vertical supports 900 can in turn be fastened to a building or part of a building that is scaffolded with the scaffolding system 1000. The at least one panel assembly 200 can, for example, be attached to an outside side as seen from the building, for example to serve as a safety system, in particular as a fall protection device, for persons on the scaffolding system 1000. Furthermore, the at least one panel assembly 200 can also serve as a visual screen and / or as weather protection, in particular as a windbreak, and / or as an advertising space. As described in connection with Figure 1, the panel elements 100 are mechanically connected to one another by means of plug-in connectors.

[0068] Figures 6A to 6C show parts of a plug connector 30 according to an exemplary embodiment. Figure 6A shows a three-dimensional oblique view, while Figure 6B shows a sectional view and Figure 6C shows a plan view. In particular, Figures 6A to 6C show the first connection region 31 of the plug connector 30 described in connection with Figure 1, which is provided and configured for insertion into a region of the profile frame of a panel element. In particular, the first connection region 31 is provided and configured for insertion into a horizontal frame element of a profile frame of a panel element.

[0069] The plug connector 30 has a base plate 310. The base plate 310 has a first main surface 311 and a second main surface 312 opposite the first main surface 311, which are connected to one another by one or more side surfaces. The base plate 310 is particularly preferably flat as shown, so that the first and second main surfaces 311, 312 can be parallel to one another. The base plate 310 has a height which is smaller than a length and a width. The height is defined as the distance between the first and second main surfaces 311, 312. The length and width are two dimensions which are perpendicular to one another and which are both in turn perpendicular to the height, so that the length and width are parallel to the first and second main surfaces 311, 312. The length may preferably be the largest extent of the base plate 310 along the first and second main surfaces 311, 312.Lengths, widths and heights of other parts of the connector 30 may be dimensions in corresponding directions.

[0070] The base plate 310 has a fixing region 300. In the fixing region 300, a first stop element 330 is formed on the first main surface 311, which is provided and configured, in a state mounted on a panel element, to be pressed with at least one surface against a part of a frame element of the profile frame of the panel element, in particular into a recess 19 of a horizontal frame element 10, as described in connection with Figures 2A to 3B.

[0071] Furthermore, the base plate 310 has a first insertion region 301. At least the first insertion region 301 or preferably the first insertion region 301 and a part of the fixing region 300 are designed and configured to be inserted into a frame element of a panel element, for example a horizontal frame element, and to be further fixed there. The first insertion region 301 is in particular that region of the plug connector 30 with which the plug connector 30 is inserted into the frame element and then pushed further until preferably a part of the fixing region 300 is also pushed in. The arrangement direction from the fixing region 300 to the first insertion region 301 defines a first insertion direction 303 of the plug connector 30 for insertion into a frame element of a panel element.In particular, the previously described length is particularly preferably dimensioned along the first insertion direction 303, while the width and height are each perpendicular to the first insertion direction 303. In particular, the first insertion region 301 and a first part of the fixing region 300, together with a part of the first stop element 330, form the first connecting region 31 for a panel element, into whose frame element the first insertion region 301 is inserted.

[0072] Furthermore, the base plate 310 has a first fastening opening 313 for a securing element. As shown, the first fastening opening 313 can be formed in the first insertion region 301. In particular, after the first insertion region 301 or the first insertion region 301 and a part of the fixing region 300 have been pushed into the frame element of a profile frame of a panel element, the first fastening opening 313 overlaps with at least one mounting hole in the frame element, so that a securing element 102 can be pushed through the at least one mounting hole and the first fastening opening 313. As a result, the plug connector 30 can be mechanically fastened to a panel element. For better understanding, Figure 6A shows a securing element 102 designed as a bolt inserted into the first fastening opening 313. Furthermore, a spring lock 103 is shown for securing the securing element 102.Of course, the securing element 102 and the spring lock 103 are only inserted into the fastening opening 313 after the first connecting area 31 has been inserted into a frame element of a panel element.

[0073] Particularly preferably, the region of the frame element into which the plug connector 30 is inserted with the first insertion region or the first insertion region and a part of the fixing region preferably has two plate-shaped regions provided with mounting holes, between which at least a part of the first connecting region 31 is arranged during insertion. The two plate-shaped regions can, for example, be parts of a square profile, as described in connection with Figures 2A to 3B.

[0074] In the exemplary embodiment shown, the first insertion region 301 tapers in the direction away from the fixing region 300. The first insertion region 301 therefore preferably has a decreasing width in a direction along the insertion direction 303 away from the fixing region 300. The first insertion region 301 is thus conical in terms of width and has two insertion bevels 315 which are formed by side surfaces of the base plate 310, as can be seen in Figures 6A and 6C. The first insertion region 301 is preferably designed symmetrically with respect to a plane of symmetry perpendicular to the width direction. The first connecting region 31 or the entire base plate 310 is particularly preferably designed correspondingly symmetrically.

[0075] The first stop element 330 protrudes from the base plate 310, in particular from the first main surface 311 of the base plate 310. Particularly preferably, the first stop element 310 does not protrude laterally beyond the base plate 310, i.e. in a direction perpendicular to the first insertion direction 303 along the plane of the first main surface 311, but rather extends with a main extension direction perpendicular away from the first main surface 311. In other words, the first stop element 330 is preferably not wider than the base plate 310. The first stop element 330 is preferably formed integrally with the base plate 310. Alternatively, the first stop element 330 can also be fastened to the base plate 310, for example by means of welding or clamping.

[0076] In the exemplary embodiment shown, the first stop element 330 has a cylindrical shape with a hexagonal cross-section. In particular, the cross-section can relate to a base surface 331 of the first stop element 330, the base surface 331 in the exemplary embodiment shown being the imaginary surface which borders on the first main surface 311 and which is indicated by a dashed line in Figure 6B. Opposite this imaginary base surface 331, the first stop element 330 has an upper side surface 332 which faces away from the first main surface 311 and with which the first stop element 330 terminates in a direction away from the first main surface 311. Particularly preferably, the base surface 331 and the upper side surface 332 have the same shape, as in the exemplary embodiment shown.The distance of the base surface 331 and thus the first main surface 311 to the top surface 332 defines the height of the first stop element 330.

[0077] In the exemplary embodiment shown, the base surface 311 and the upper side surface 332 are connected to one another by a plurality of side surfaces 333 which are connected by edges and which can also be referred to as jacket surfaces. Parts of the side surfaces 333 of the first stop element 330 are provided and designed to be pressed against a recess 19 shown in Figures 2C to 3B in the profile frame 1, in particular in a frame element, of a panel element when the plug connector 30 is fastened to the frame element as described above with the securing element 102 inserted through the first fastening opening 313. Particularly preferably, the first stop element 330 is provided and designed to engage in a form-fitting manner with part of the side surfaces 333 in a recess in a wall of a frame element of a panel element, which recess is correspondingly designed as part of a negative form of the cross section of the first stop element 330.This part of the side surfaces 333 thus forms part of the first connecting region 31.

[0078] Further developments and modifications of the connector 30 are described in conjunction with the figures described below. Features and parts of the connector 30 that are not described explicitly below can be designed as described in previous embodiments.

[0079] 7A to 7E according to further embodiments in views corresponding to the view in Figure 6C, the first stop element 330 can also have a different cross-sectional shape and thus a different shape of the base surface 331 and the top surface 332 than a hexagonal shape. For example, the cross-sectional shape can be triangular (Figure 7A), square (Figure 7B) or rectangular, diamond-shaped (Figure 7C) or octagonal (Figure 7D). In addition, other polygonal shapes, in particular irregular polygonal shapes, are also possible. Furthermore, the cross-sectional shape can also be round, for example circular or elliptical (Figure 7E). In this case, the first stop element 310 has a curved, completely circumferential side surface 333. In addition, combinations of the shapes shown or other polygonal and round shapes are also possible.

[0080] As an alternative to a cylindrical shape, the first stop element 330 can also have a truncated pyramid shape or a truncated cone shape, depending on the polygonal or round cross-sectional shape, as indicated in the views in Figures 8A and 8B corresponding to Figure 6B. In this case, the first stop element 330 can taper (Figure 8A) or enlarge (Figure 8B) with respect to the cross-sectional area from the first main surface 311 to the top surface 332.

[0081] 9A and 9B, a second stop element 340 can be formed on the second main surface 312 of the base plate 310 in the fixing region 300, said second main surface 312 being opposite the first main surface 311. The first connecting region 31 also has a first part of the second stop element 340. All features and properties for the first stop element 330 can preferably also apply to the second stop element 340. As shown in Figure 9A, the first and second stop elements 330, 340 can be of the same design. Alternatively, as indicated in Figure 9B, the first and second stop elements 330, 340 can be of different design.Furthermore, as indicated in Figure 9C, the base plate 310 can have a plurality of plate elements 3101 arranged one above the other in the height direction, i.e., in a direction perpendicular to the first main surface 311. The plate elements can be connected to one another, for example, via one or more plate connecting elements 3102, as indicated in Figure 9C. Alternatively, the plate elements 3101 can also be arranged one above the other without a fixed connection.

[0082] Figures 10A and 10B show, in views corresponding to the views in Figures 6A and 6B, a further exemplary embodiment of the plug connector 30, which has a second connection region 32 for a further panel element. The second connection region 32 has a second insertion region 302 and a second part of the fixing region 300, the fixing region 300 being arranged between the first and second insertion regions 301, 302. The second connection region 32 has, in the second insertion region 302, a second fastening opening 314 for a securing element 102, which is indicated together with a spring lock 103 in Figure 10A. The arrangement direction from the fixing region 300 to the second insertion region 302 defines a second insertion direction 304 of the connector 30 for insertion into a frame element of the further panel element.Accordingly, in this exemplary embodiment, both connection regions 31, 32 of the connector 30 are each designed for insertion into a frame element of a respective panel element. The first and second insertion directions 303, 304 are preferably antiparallel to one another, as indicated in Figures 10A and 10B, so that the two said panel elements can be pushed onto the connector 30 in direct extension of one another and fixed to one another by the connector, as described further below in connection with Figures 14A and 14B.

[0083] The second connection region 32 can in particular have features and properties that are described in connection with the first connection region 31. The first connection region 31 and the second connection region 32 are particularly preferably designed identically. In particular, the second insertion region 302 can be designed identically to the first insertion region 301. Furthermore, the first part of the fixing region 300 of the first connection region 31 is preferably designed identically to the second part of the fixing region 300 of the second connection region 32. The plug connector 30 is particularly preferably designed symmetrically with respect to a plane of symmetry perpendicular to the first and second insertion directions 303, 304.

[0084] As shown in Figure 11 using a further exemplary embodiment, a second stop element 340 can additionally be formed on the second main surface 312 of the base plate 310, as described in connection with Figures 9A and 9B. Thus, the connector 30 can particularly preferably be symmetrical with respect to three planes of symmetry that are perpendicular to the length direction, the width direction, and the height direction.

[0085] For purely exemplary purposes, the stop elements in the following embodiments are shown as cylindrical with a hexagonal cross-section. However, they can also have other shapes than those described above.

[0086] In Figures 12A and 12B, in views corresponding to Figures 10A and 10B, a further embodiment of the connector 30 is shown, which corresponds to the embodiment of Figure 11 and which further has a first positioning element 351 on the first main surface in the first connection region 31 and a further first positioning element 352 on the first main surface 311 in the second connection region 32.

[0087] The first positioning element 351 is formed on the first main surface 311 between the first stop element 330 and the first fastening opening 313 in the form of an elevation on the base plate 310. The first positioning element 351 can in particular be an elevation, for example a fin, which extends over part of the first main surface 311. The first positioning element 351 can have a main extension direction in the longitudinal direction, i.e. along the first insertion direction 303, or alternatively also in the transverse direction, i.e. perpendicular to the first insertion direction 303, and can also extend, for example, over the entire width of the base plate 310. Particularly preferably, the first positioning element has a main extension direction along the first insertion direction 303, as shown in Figures 12A and 12B, and thus extends elongatedly along the first insertion direction 303.Furthermore, the first positioning element 351 has, for example, an insertion bevel facing away from the first stop element 330, which is thus formed along the first insertion direction 303 at the front of the first positioning element 351, which is preferably designed as a fin. The first positioning element 351 is preferably arranged partly in the fixing region 300 and partly in the first insertion region 301. The further first positioning element 352 in the second connecting region 32 is preferably designed the same as the first positioning element 351 in the first connecting region 31 and is preferably designed and arranged mirror-symmetrically thereto with respect to a plane of symmetry perpendicular to the insertion directions 303, 304.

[0088] According to a further exemplary embodiment, which is shown in Figure 13, a second positioning element 353 in the form of an elevation on the base plate 310 on the second main surface 312 in the first connecting region 31 is formed on the second main surface 312 of the base plate 310, which is opposite the first main surface 311. Furthermore, a further second positioning element 354 in the form of an elevation is preferably also formed on the base plate 310 in the second connecting region 32 on the second main surface 312. All features and properties for the first positioning elements 351, 352 can preferably also apply to the second positioning elements 353, 354. The first and second positioning elements 351, 352, 353, 354 are particularly preferably designed identically. Alternatively, the first and second positioning elements 351, 352, 353, 354 may also be designed differently.

[0089] The base plate 310, the first positioning elements 351, 352 and the second positioning elements 353, 354 can each together have a height that is adapted to the profile of the frame elements of the panel elements into which the first connecting region 31 and the second connecting region 32 are respectively inserted, as described in the general part. Furthermore, the fixing region 300 can have a width that is adapted to the profile of the frame elements of the panel elements into which the first connecting region 31 and the second connecting region 32 are inserted, as described in the general part. Figures 14A and 14B show a three-dimensional view and an associated cutaway view of a panel assembly 200 with two panel elements 100 that are connected to one another by two plug-in connectors 30.The connector 30 can be designed, for example, as described in connection with Figure 13. Furthermore, designs according to the other embodiments or combinations thereof are also possible.

[0090] In particular, the panel assembly 200 is shown in a state during assembly in which the plug-in connectors 30 have already been pushed into a first panel element 100 and fixed by means of securing elements 102 and spring locks 103. The second panel element 100 is shown at the moment before being pushed onto the two plug-in connectors 30, i.e. at the moment before the plug-in connectors 30 are pushed into the profile frame of the second panel element 100, as indicated by the pushing-on direction 94 in Figure 14A. The described plug-in connector 30 of the exemplary embodiments of Figures 10A to 13 enables a flat panel element arrangement.By means of conically shaped securing elements 102, such as conically shaped bolts, a pulling movement of the panel elements 100 with the recesses 19 towards the stop elements 320, 340 can be achieved when these are inserted into the fastening openings 313, 314 of the plug-in connectors 30 and the mounting holes of the profile frames 1. The positioning elements, in turn, can prevent undesired tilting of the plug-in connectors 30. Thus, by shaping the stop elements of the plug-in connectors 30 together with the correspondingly shaped recesses 19 in the profile frames 1 of the panel elements 100, a positive connection without play is possible after assembly. The panel assembly 200 can be expanded accordingly by means of further plug-in connectors 30, which are shown in Figure 14A already mounted on the second panel element 100, and further panel elements 100.

[0091] Figures 15A to 15D show a connector 30 and a panel assembly 200 according to further exemplary embodiments. The views of the connector 30 shown in Figures 15A and 15B correspond to the views in Figures 12A and 12B. In Figure 12B, the horizontal frame element 10 of a profile frame 1 of a panel element is indicated by dashed lines. Figures 12C and 12D show a three-dimensional detail view and a three-dimensional overall view of the panel assembly 200. The following description refers equally to Figures 15A to 15D.

[0092] The first connection region 31 is designed as described in connection with the previous exemplary embodiments and, purely by way of example, has no positioning elements on the base plate 310. In comparison to the exemplary embodiments in Figures 10A to 13, in the connector 30 shown in Figures 15A to 15D, the second connection region 32 is designed with a first plate element 321 and a second plate element 322, which are spaced apart from one another in a direction perpendicular to the first and second main surfaces 311, 312 and which are provided and configured to partially encompass part of a profile frame 1 of a panel element 100. In particular, as can be seen in Figures 15B, 15C and 15D, part of a horizontal frame element 10 of one of the panel elements, to which the second connection region 32 of the connector 30 is fastened, is encompassed.Thus, while the first connecting region 31 is designed, as in the previous embodiments, for insertion into a frame element of a profile frame 1 of a first panel element 100, the second connecting region 32 is provided and designed for mounting externally on the frame element of a profile frame 1 of a second panel element 100.

[0093] The first and second plate elements 321, 322 each have at least two second fastening openings 314 for a respective securing element 102, so that, as shown in Figure 15A, a respective securing element 102 can be pushed through a pair formed from a second fastening opening 314 of the first plate element 321 and a second fastening opening 314 of the second plate element 322. The second fastening openings 314 thus overlap in pairs in a plan view along the height direction. Between the paired second fastening openings 314, through which a common securing element 102 is pushed, at least one mounting hole 18 of the frame element of the profile frame 1 is arranged in the mounted state of the plug connector 30, through which the securing element 102 is also pushed.For example, the first plate element 321 can be fixed to the first stop element 330 and the second plate element 322 can be fixed to the second stop element 340, for example integrally formed or welded.

[0094] The arrangement direction of the at least two second fastening openings 314 of the first plate element 321 and the at least two second fastening openings 314 of the second plate element 322 can enclose an angle of greater than or equal to 0° and less than or equal to 180° with the first insertion direction 303. This makes it possible to define an angle at which the two interconnected panel elements 100 are positioned relative to one another. The arrangement direction and the first insertion direction 303 can, for example, be perpendicular to one another, so that, as shown in Figures 15C and 15D, a perpendicular arrangement of the panel elements 100 relative to one another is possible. Accordingly, with the connector 30 shown in Figures 15A to 15D, a wind vane-like connection of a further panel element 100 that can be displaced along the length of a panel element 100 is possible, as indicated by the displacement direction 95 in Figure 15D.

[0095] Figures 16A to 16C show further exemplary embodiments of a plug connector 30 in a three-dimensional view and of a panel assembly 200 in a three-dimensional partial view and a three-dimensional overall view. The following description refers equally to Figures 16A to 16C. In comparison to the embodiment of the plug connector 30 according to Figures 15A to 15D, here the first and second plate elements 321, 322 of the second connecting region 32 are part of a U-profile that is fixed to the base plate 310 with the first connecting region 31, i.e., is welded or formed in one piece. Furthermore, the arrangement direction of the at least two second fastening openings 314 of the first plate element 321 and the at least two second fastening openings 314 of the second plate element 322 is parallel to the first insertion direction 303 of the first connecting region 31.As a result, the connector 30 in this exemplary embodiment forms an adjustment adapter to enable length compensation in the hole pattern of the mounting holes 18 with panel elements 100 passing by one another, as indicated by the displacement direction 95 in Figure 16C. The panel element 100 connected to the first connection region 31 of the connector 30 can, for example, be a stationary panel element 100, while the panel element 100 connected to the second connection region 32 can be adjusted in its position relative thereto.

[0096] Figures 17A and 17B show exemplary embodiments of a plug connector 30 and a scaffolding system 1000 with a panel assembly 200 according to further exemplary embodiments in views of the first main surface 311 of the plug connector 30. In these exemplary embodiments, the base plate 310 is T-shaped and has a second connecting region 32 for a further panel element with two second fastening openings 314, each for a securing element 102. In particular, in this embodiment, the second connecting region 32 is formed by a part of the base plate 310. As shown, the two second fastening openings 314 preferably have an arrangement direction that is perpendicular to the first insertion direction 303.This may mean that the at least one first fastening opening 313 of the first connecting region 31 and the two second fastening openings 314 of the second connecting region 32 are located on the corners of an imaginary isosceles triangle.

[0097] In particular, the second connecting region 32 is provided and configured to be mounted on receiving elements 16 provided and configured for this purpose. For example, the receiving elements 16 can be mounting tabs with mounting holes on the profile frame 1 of one of the panel elements 100, between which the base plate 310 is arranged. In particular, the second connecting region can be provided and configured to be partially arranged between mounting tabs of the further panel element and fastened by means of at least one securing element 102.

[0098] As can be seen in Figure 17B, a panel element 100 can be fixedly mounted on vertical supports 900 of the scaffolding system. The plug connector 30 and one of the receiving elements 16 can form a hinge about which the plug connector 30 and the panel element 100 connected to the first connecting region 31 can rotate. The other of the receiving elements 16, which is not connected to the plug connector 30 in Figure 17B, can form a lock with a further securing element 102 when the rotatable panel element 100 is folded out and thus aligned in extension to the stationary panel element 100. The plug connector 30, together with the receiving elements 16, can form a play-free, lockable hinge, wherein a receiving element 16 forms a hinge support and the plug connector 30 forms a hinge wing.

[0099] Figures 18A to 18L show various views of the panel assembly 200 and the scaffolding system 1000 according to Figures 17A and 17B. Figure 18A shows an exploded view of the panel assembly 200 in the folded state. Figures 18B to 18D show a detail view, a three-dimensional view and a plan view of the scaffolding system 1000 in the state shown in Figure 17B, in which the rotatable panel element 100 is folded in, wherein the scaffolding system 1000 has a plurality of panel assemblies 200 fastened one above the other to vertical supports 900 and each panel assembly 200 has two rotatably mounted panel elements 100 and two stationary panel elements 100 in between. Figures 18E and 18F show stages during the unfolding of a pivotally mounted panel element 100 in detail views.In Figures 18G and 18H, the pivotally mounted panel elements 100 are shown unfolded by approximately 45° in a three-dimensional view and a plan view, while the pivotally mounted panel elements 100 are shown in Figures 18I to 18L in corresponding representations in fully unfolded states, wherein Figure 18I is an exploded view of Figure 18J.
