Description

[0001] 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.

[0002] So-called enclosure panels are known for scaffolding systems. These panels are attached, for example, to the exterior of a scaffold, climbing formwork, or a structure under construction or restoration to enclose the scaffold or the structure under construction or restoration. They can serve for safety, as well as as a visual barrier and / or protection from environmental influences such as wind and solar radiation. Such enclosure panels are usually installed with screw fastenings or clamps, which, however, require tools. Furthermore, the installation of such panels is often cumbersome and time-consuming, and a wide range of products is necessary to meet diverse installation-specific requirements. Therefore, a simplified assembly system for such panels is desirable.

[0003] 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.

[0004] These objects are achieved by subject matter according to the independent patent claims. Advantageous embodiments and further developments of the subject matter are characterized in the dependent claims and will further become apparent from the following description and the drawings.

[0005] 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 applies equally to the connector, the panel assembly with the connector, and the scaffolding system with the panel assembly.

[0006] In a preferred embodiment, a connector for connecting panel elements for a scaffolding system has the following features: - 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, - a first fastening opening for a first securing element, - 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.

[0007] The scaffolding system may, for example, comprise a formwork system. Formwork systems for erecting structures are used to produce building components, such as walls or ceilings, and are generally designed to create a backfill space for a hardenable building material, such as concrete. The building material can be poured into the backfill space and, once hardened, form the desired building component. Alternatively or additionally, the scaffolding system may comprise 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 constructed in sections, which, after curing, the climbing system can climb up to continue erecting the building. In particular, the scaffolding system can preferably include or be a formwork system and a climbing system.

[0008] 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.

[0009] 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 that are connected to one another to form a rectangular shape. Terms such as "horizontal" and "vertical" can, here and below, 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.

[0010] 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. In particular, the frame elements can be provided with mounting holes designed and configured to accommodate securing elements.

[0011] Here and below, a securing element can be selected in particular from bolts, screws, rivets and pins.

[0012] In particular, the scaffolding system can comprise at least one support, which is attached, for example, to a building or a part of a building. For example, the support can be a vertical support. The at least one panel assembly can be attached to the support directly or indirectly, for example, via one or more struts. These can be screwed or bolted struts, for example, which can be attached, for example, directly to a profile frame of a panel element and to a support of the scaffolding system.

[0013] By means of at least one connector, two panel elements 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 similarly designed connectors. The connector described here can in particular have a first connection area for mechanically connecting the connector to a first of two panel elements and a second connection area for mechanically connecting the connector to a second of the two panel elements. A mechanical connection can in particular mean a positive connection or a non-positive connection or a positive and non-positive connection. Particularly preferably, the connection can be released by removing the connector(s), so that the panel assembly can be disassembled into individual panel elements again.

[0014] 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 steel and / or aluminum. A combination of different parts made of different materials is also possible.

[0015] According to a further embodiment, the 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.

[0016] 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. Thus, the base plate can have a plurality of plate elements 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 that can form the base plate, the 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.

[0017] 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.

[0018] 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 configured to be inserted into a frame element of a panel element and 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 further inserted until preferably a part of the fixing region is also inserted. 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.

[0019] 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 inserted 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. This allows the connector to be mechanically fastened to a panel element.Particularly preferably, the region of the frame element into which the 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 connection 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 connector, and then through one of the mounting holes of the other of the two plate-shaped regions of the frame element.

[0020] According to a further embodiment, the first insertion region tapers in the direction away from the fixing region. The first insertion region thus 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 thus 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 designed symmetrically with respect to a plane of symmetry perpendicular to the width direction. Furthermore, the first connecting region or else the base plate can be designed correspondingly symmetrically.

[0021] 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.

[0022] 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.

[0023] 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 has a round shape or a polygonal shape, or a combination thereof, when viewed towards the first main surface. In particular, the cross-section can relate to a base surface of the first stop element, wherein the base surface 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 surface 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 terminates in a direction facing away from the first main surface. Particularly preferably, the base surface and the upper side surface have the same shape. The distance between the base surface and thus the first main surface and the upper side surface defines the height of the first stop element. Particularly preferably, the first stop element 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.

[0024] The base surface and the upper side surface are connected to one another by a circumferential, curved side surface or by several side surfaces connected by edges, which can also be referred to as lateral 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 with a part of the side surface(s) in a recess in a wall of a frame element of a panel element in a form-fitting manner. This part of the side surface(s) thus forms part of the first connection region.

[0025] 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 comprises 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.

[0026] 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, across 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 fixation region and partially in the first insertion region.

[0027] According to a further embodiment, a second positioning element in the form of a raised portion 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.

[0028] 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, when inserted, can bear tightly against the frame element or, preferably, can also have some play, for example, to facilitate insertion. 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.Thus, in the inserted state, the fixing region can be in close contact with the frame element with regions of the circumferential side surface that connect the first and second main surfaces, or can also preferably have some play, for example, to facilitate insertion. While the fixing region can thus be provided and configured to provide lateral guidance of the connector in the frame element, the positioning elements can be provided and configured to provide vertical guidance.

[0029] According to a further embodiment, the fixing region and the first insertion region are formed 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 connector can be formed identically at least in the fixing region and in the first insertion region. Particularly preferably, the entire connector can be formed symmetrically with respect to the plane of symmetry parallel to the first main surface. This can facilitate assembly of the connector.

[0030] 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 antiparallel, so that the two panel elements can be pushed onto the connector in direct extension to each other and fixed to each other by the latter.

[0031] 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 designed identically. This can mean, in particular, that the first connection region and the second connection region can preferably be designed substantially symmetrically to the fixing region. In particular, the second insertion region can be designed identically to the first insertion region. Furthermore, the first part of the fixing region of the first connection region can be designed identically to the second part of the fixing region of the second connection region. The plug connector is particularly preferably designed symmetrically with respect to a plane of symmetry perpendicular to the first and second insertion directions.

[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 connection region is designed for insertion into a frame element of a profile frame of a first panel element, the second connection region is provided and configured 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 vertical direction. When the connector is in the assembled state, 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 defining an angle at which the two interconnected panel elements are positioned relative to each other. The arrangement direction and the first insertion direction are preferably perpendicular or parallel to each other.

[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, the first plate element and the second plate element can 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 connection region for a further panel element. In particular, in this embodiment, the second connection region can be formed by a part of the base plate. In particular, the second connection 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 connection 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 area 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 area can also have a second fastening opening for yet another securing element, with which the second connection area can be fixed to the further panel element in such a way 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 additional panel element. Furthermore, it is also possible that no second fastening opening is present. In this case, the additional panel element can be held at a different location relative to the first panel element.

[0039] To form a panel assembly, the connector, as described above, is inserted with the first connection area, i.e. with the first insertion area and preferably a part of the fixing area, 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 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 area is fastened and secured to the first panel element and the second connection area to the second panel element, each with at least one securing element. Particularly preferably, the two panel elements are connected to one another by two connectors. Two panel elements can preferably also be connected with three or more connectors.The connectors can be designed the same.

[0040] 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.

[0041] The panel assembly can 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 according to the previously described embodiments.

[0042] The connector described here, according to the described embodiments, can be used in a variety of ways for straight, angled, offset, split, and / or hinged panel element arrangements. For example, in a corner connector design, it is possible to arrange panel elements at an angle of 90° or even at a different angle to one another. Regardless of the specific embodiment, the connector described here preferably allows for a completely play-free panel element connection and force transmission. This advantageously results in the prevention of movement and rattling noises in the panel assembly. Furthermore, simple assembly is possible with only two or three securing elements such as bolts, 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.

[0043] The connector described here can, regardless of the specific design according to the described embodiments, allow a force-fitting, positive-locking, 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 abuts 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.

[0046] In Fig. 1 shows a schematic representation of a panel assembly 200 according to one embodiment. The panel assembly 200 may, in particular, be part of a scaffolding system, which will be explained further below in connection with some embodiments. In particular, the panel assembly 200 comprises at least two panel elements 100 that can be connected to one another by means of at least one connector 30. Fig. 1, the panel elements 100 and the connector 30 are shown in a state in which they are not yet mechanically connected to one another for the sake of clarity, with the operative connection between the panel elements 100 and the connector 30 being indicated by the double arrows. 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 intended installation of the panel elements 100 in the panel assembly 200 and in the scaffolding system.Accordingly, in some figures, the horizontal direction 91 and the vertical direction 92 are indicated to indicate the orientation of pan elements as required. Additionally, in some figures, such as in the . Fig. 2A to 5 and in further figures, a depth direction 93 is indicated, which is perpendicular to the horizontal direction 91 and perpendicular to the vertical direction 92. The connector 30 has, in particular, 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 can, in particular, mean a positive and non-positive connection.

[0047] In the Fig. 2A to 2D show schematic representations of different views of a panel element 100 according to an embodiment. In Fig. 2A shows a three-dimensional view of the panel element 100. In the Fig. 2B, Fig. 2C and Fig. 2D, parts of the panel element 100 are shown in detail. The following description refers equally to the Fig. 2A to 2D.

[0048] The panel element 100, as described above, has a profile frame 1 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 that runs along the horizontal direction 91. Each of the vertical frame elements 20 has a main extension direction that 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 that 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 may be formed by a perforated sheet, for example, can be mounted on the profile frame 1, for example by screwing or riveting.

[0049] 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 the Fig. 2C and Fig. 2D, as hollow profiles, in particular as square profiles 11. The vertical frame elements 20 are, as shown in detail in Fig. 2B, are formed 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.

[0050] 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 some are provided with reference numerals 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 in connection with the Fig. 4A and Fig. 4B is shown.

[0051] As in the Fig. 2C and Fig. 2D, the horizontal frame elements 10 have horizontal end regions 15 in which recesses 19 are formed, which are provided and designed so that parts of stop elements of plug-in connectors can engage, as described further below.

[0052] As in the Fig. 3A and Fig. 3B, which reflects the views of the Fig. 2C and Fig. 2D, based on 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. Furthermore, other combinations of profiles are also possible.

[0053] In the Fig. 4A and Fig. 4B shows a panel element 100 in an exploded view and in a finished state, which has a profile frame 1 with a plate 2 mounted thereon, as described in connection with the Fig. 2A to 3B. An insert element 3, for example a corrugated sheet with or made of plastic as a privacy and / or wind protection, is fastened to 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 folded up and attached to the profile frame 1 for mounting the panel element 100 in a panel assembly and further in a scaffolding system, and can be unfolded after assembly as needed.

[0054] Fig. 5 shows a schematic representation of a section of an embodiment of a scaffolding system 1000 with at least one panel assembly 200 with panel elements 100, which, as in connection with the Fig. 4A and Fig. 4B. Purely by way of example, a folding platform 5 is shown folded in on one of the panel elements 100, 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, for example, be screwed or bolted struts, which can, for example, 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 attached 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 mounted on an exterior side as viewed 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 privacy screen and / or as weather protection, in particular as wind protection, and / or as an advertising space. As described in connection with the . Fig. 1, the panel elements 100 are mechanically connected to one another by means of connectors.

[0055] In the Fig. 6A to 6C show parts of a connector 30 according to an embodiment. In Fig. 6A shows a three-dimensional oblique view, while in Fig. 6B a sectional view and in Fig. 6C are shown in a top view. In particular, the Fig. 6A to 6C in connection with the Fig. 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.

[0056] The 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. Particularly preferably, the base plate 310 is 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 that is less 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 mutually perpendicular dimensions, which in turn are both perpendicular to the height, so that the length and width are parallel to the first and second main surfaces 311, 312. The length can preferably be the greatest 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.

[0057] The base plate 310 has a fixing area 300. In the fixing area 300, a first stop element 330 is formed on the first main surface 311, which is provided and configured to, in a state mounted on a panel element, bear 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 in connection with the Fig. 2A to 3B described.

[0058] 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 further inserted until, preferably, a part of the fixing region 300 is also inserted. 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.

[0059] 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. This allows the connector 30 to be mechanically fastened to a panel element. Fig. 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 region 31 has been inserted into a frame element of a panel element.

[0060] Particularly preferably, the area of the frame element into which the plug connector 30 is inserted with the first insertion area or the first insertion area and a part of the fixing area preferably has two plate-shaped areas provided with mounting holes, between which at least a part of the first connection area 31 is arranged during insertion. The two plate-shaped areas can, for example, be parts of a square profile, as in connection with the Fig. 2A to 3B.

[0061] In the illustrated embodiment, the first insertion region 301 tapers in the direction away from the fixing region 300. The first insertion region 301 thus 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 width and has two insertion bevels 315, which are formed by side surfaces of the base plate 310, as shown in the Fig. 6A and Fig. 6C. Preferably, the first insertion region 301 is formed symmetrically with respect to a plane of symmetry perpendicular to the width direction. Particularly preferably, the first connecting region 31 or the entire base plate 310 is formed correspondingly symmetrically.

[0062] 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 perpendicularly away from the first main surface 311 in a main extension direction. In other words, the first stop element 330 is preferably not wider than the base plate 310.

[0063] The first stop element 330 is preferably formed integrally with the base plate 310. Alternatively, the first stop element 330 can also be attached to the base plate 310, for example, by welding or clamping.

[0064] In the illustrated embodiment, the first stop element 330 has a cylindrical shape with a hexagonal cross-section. In particular, the cross-section can refer to a base surface 331 of the first stop element 330, wherein the base surface 331 in the illustrated embodiment refers to the imaginary surface that borders the first main surface 311 and which in Fig. 6B is indicated by dashed lines. Opposite this imaginary base surface 331, the first stop element 330 has an upper 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 surface 332 have the same shape, as in the illustrated embodiment. The distance between the base surface 331 and thus the first main surface 311 and the upper surface 332 defines the height of the first stop element 330.

[0065] In the illustrated embodiment, the base surface 311 and the upper surface 332 are connected to one another by a plurality of side surfaces 333 connected by edges, which can also be referred to as lateral surfaces. Parts of the side surfaces 333 of the first stop element 330 are provided and designed to bear against a Fig. 2C to 3B, when the 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 a portion of the side surfaces 333 in a recess in a wall of a frame element of a panel element, which recess is correspondingly formed as part of a negative form of the cross section of the first stop element 330. This portion of the side surfaces 333 thus forms part of the first connection region 31.

[0066] 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 explicitly described below can be designed as described in previous embodiments.

[0067] As in connection with the Fig. 7A to 7E according to further embodiments in views corresponding to the view of Fig. 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 ( Fig. 7A), square ( Fig. 7B) or rectangular, diamond-shaped ( Fig. 7C) or octagonal ( Fig. 7D). In addition, other polygonal shapes, especially irregular polygonal shapes, are also possible. Furthermore, the cross-sectional shape can also be round, for example circular or elliptical ( Fig. 7E). In this case, the first stop element 310 has a curved, completely circumferential side surface 333.

[0068] In addition, combinations of the shapes shown or other polygonal and round shapes are also possible.

[0069] 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 shown in the Fig. 6B corresponding views in the Fig. 8A and Fig. 8B. The first stop element 330 can taper in terms of cross-sectional area from the first main surface 311 to the top surface 332 ( Fig. 8A) or enlarge ( Fig. 8B).

[0070] In addition to the first stop element 330 on the first main surface 311, as shown in the Fig. 9A and Fig. 9B, a second stop element 340 may be formed on the second main surface 312 of the base plate 310, which is opposite the first main surface 311, in the fixing region 300, wherein 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 may preferably also apply to the second stop element 340. As in Fig. 9A, the first and second stop elements 330, 340 may be of the same design. Alternatively, as shown in Fig. 9B, the first and second stop elements 330, 340 can be designed differently. Furthermore, as in Fig. 9C, the base plate 310 comprises 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 shown in Fig. 9C. Alternatively, the plate elements 3101 can also be arranged one above the other without a fixed connection.

[0071] In the Fig. 10A and Fig. 10B is in views corresponding to the views of the Fig. 6A and Fig. 6B, a further embodiment of the connector 30 is shown, 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, wherein the fixing region 300 is 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 together with a spring lock 103 in Fig. 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 as shown in the Fig. 10A and Fig. 10B, preferably antiparallel to each other, so that the two said panel elements can be pushed onto the connector 30 in direct extension to each other and fixed to each other by this, as further below in connection with the Fig. 14A and Fig. 14B is described.

[0072] 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-in connector 30 is particularly preferably designed symmetrically with respect to a plane of symmetry perpendicular to the first and second insertion directions 303, 304.

[0073] As in Fig. 11 using a further embodiment, a second stop element 340 can additionally be formed on the second main surface 312 of the base plate 310, as in connection with the Fig. 9A and Fig. 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.

[0074] For purely exemplary purposes, the stop elements in the following exemplary embodiments are shown as cylindrical with a hexagonal cross-section. However, they can also have other shapes as described above.

[0075] In the Fig. 12A and Fig. 12B is in the Fig. 10A and Fig. 10B, a further embodiment of the connector 30 is shown, which corresponds to the embodiment of the Fig. 11 and which further comprises a first positioning element 351 on the first main surface in the first connecting region 31 and a further first positioning element 352 on the first main surface 311 in the second connecting region 32.

[0076] 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 a 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 extend, for example, over the entire width of the base plate 310. Particularly preferably, the first positioning element has, as shown in the Fig. 12A and Fig. 12B, the first positioning element 351 has a main extension direction along the first insertion direction 303 and thus extends longitudinally 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 partially in the fixing region 300 and partially 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.

[0077] According to a further embodiment described in Fig. 13, on the second main surface 312 of the base plate 310 opposite the first main surface 311, a second positioning element 353 is formed in the form of an elevation on the base plate 310 on the second main surface 312 in the first connecting region 31. Furthermore, a further second positioning element 354 is preferably also formed in the form of an elevation 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. Particularly preferably, the first and second positioning elements 351, 352, 353, 354 are of identical design. Alternatively, the first and second positioning elements 351, 352, 353, 354 can also be of different design.

[0078] The base plate 310, the first positioning elements 351, 352, and the second positioning elements 353, 354 can each have a height 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. Furthermore, the fixing region 300 can have a width 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.

[0079] In the Fig. 14A and Fig. 14B shows a three-dimensional view and an associated cutaway view of a panel assembly 200 with two panel elements 100 that are connected to each other by two connectors 30. The connectors 30 can, for example, be arranged as in connection with the Fig. 13. Furthermore, designs according to the other embodiments or combinations thereof are also possible.

[0080] In particular, the panel assembly 200 is shown in a state during assembly, in which the connectors 30 are already inserted 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 connectors 30, i.e. at the moment before the connectors 30 are pushed into the profile frame of the second panel element 100, as indicated by the pushing direction 94 in Fig. 14A is indicated. By the described connector 30 of the embodiments of the Fig. 10A to 13, a flat panel element arrangement is possible. 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 connectors 30 and the mounting holes of the profile frames 1. The positioning elements, in turn, can prevent undesired tilting of the connectors 30. Thus, by the shape of the stop elements of the connectors 30 together with the correspondingly shaped recesses 19 in the profile frames 1 of the panel elements 100, a positive connection after assembly without play is possible. The panel assembly 200 can be correspondingly secured by further connectors 30, which are in Fig. 14A are already shown mounted on the second panel element 100, and further panel elements 100 are extended.

[0081] In the Fig. 15A to 15D, a connector 30 and a panel assembly 200 according to further embodiments are shown. Fig. 15A and Fig. 15B shown views of the connector 30 correspond to the views of Fig. 12A and Fig. 12B. In Fig. 12B, the horizontal frame element 10 of a profile frame 1 of a panel element is indicated by dashed lines. Fig. 15C and Fig. 15D shows a three-dimensional detail view and a three-dimensional overall view of the panel assembly 200. The following description refers equally to the Fig. 15A to 15D.

[0082] The first connecting region 31 is designed as described in connection with the previous embodiments and, purely by way of example, has no positioning elements on the base plate 310. In comparison to the embodiments of the Fig. 10A to 13 is in the Fig. 15A to 15D, the second connection area 32 is formed with a first plate element 321 and a second plate element 322, which are spaced apart from each other in a direction perpendicular to the first and second main surfaces 311, 312 and which are provided and configured to partially encompass a part of a profile frame 1 of a panel element 100. In particular, as shown in the Fig. 15B, Fig. 15C and Fig. 15D, a part of a horizontal frame element 10 of one of the panel elements, to which the second connecting region 32 of the connector 30 is fastened, is encompassed. Thus, while the first connecting region 31, as in the previous exemplary embodiments, is designed 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 external mounting on the frame element of a profile frame 1 of a second panel element 100.

[0083] 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 in Fig. 15A, a 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 when viewed from above along the height direction. In the assembled state of the connector 30, at least one mounting hole 18 of the frame element of the profile frame 1 is arranged between the paired second fastening openings 314 through which a common securing element 102 is pushed, through which mounting hole 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 by being formed in one piece or welded.

[0084] The arrangement direction of the at least two second fastening openings 314 of the first panel element 321 and the at least two second fastening openings 314 of the second panel 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 can define an angle at which the two interconnected panel elements 100 are positioned relative to each other. The arrangement direction and the first insertion direction 303 can, for example, be perpendicular to each other, so that, as shown in the Fig. 15C and Fig. 15D, a perpendicular arrangement of the panel elements 100 to each other is possible. Accordingly, with the Fig. 15A to 15D, a wind vane-like connection of a further panel element 100 is possible, which can be displaced along the length of a panel element 100, as shown by the displacement direction 95 in Fig. 15D is indicated.

[0085] In the Fig. 16A to 16C show further embodiments of a connector 30 in a three-dimensional view and of a panel assembly 200 in a three-dimensional detail view and a three-dimensional overall view. The following description also refers to the Fig. 16A to 16C. Compared to the design of the connector 30 according to the Fig. 15A to 15D, 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., welded or formed integrally. 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 past one another, as indicated by the displacement direction 95 in Fig. 16C. The panel element 100 connected to the first connection area 31 of the connector 30 may, for example, be a fixed panel element 100, while the panel element 100 connected to the second connection area 32 may be adjusted in its position relative thereto.

[0086] In the Fig. 17A and Fig. 17B shows exemplary embodiments of a 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 connector 30. The base plate 310 is T-shaped in these exemplary embodiments and has a second connection 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 connection 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 can mean that the at least one first fastening opening 313 of the first connection region 31 and the two second fastening openings 314 of the second connection region 32 lie on the corners of an imaginary isosceles triangle.

[0087] 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 secured by means of at least one securing element 102.

[0088] As in Fig. 17B, a panel element 100 can be fixedly mounted on vertical supports 900 of the scaffolding system. The connector 30 and one of the receiving elements 16 can form a hinge about which the connector 30 and the panel element 100 connected to the first connecting area 31 can be rotated. The other of the receiving elements 16, which is shown in Fig. 17B is not connected to the connector 30, can form a locking mechanism with a further securing element 102 when the rotatable panel element 100 is unfolded and thus aligned in extension to the stationary panel element 100. The 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 connector 30 forms a hinge wing.

[0089] In the Fig. 18A to 18L are various views of the panel assembly 200 and the scaffolding system 1000 according to the Fig. 17A and Fig. 17B. In Fig. 18A, the panel assembly 200 is shown in an exploded view of the folded state. Fig. 18B to 18D is the scaffolding system 1000 in Fig. 17B, in which the rotatable panel element 100 is folded, in a sectional view, a three-dimensional view and a plan view, wherein the scaffolding system 1000 comprises a plurality of panel assemblies 200 fastened one above the other to vertical supports 900, and each panel assembly 200 comprises two rotatably mounted panel elements 100 and two stationary panel elements 100 therebetween. Fig. 18E and Fig. 18F show stages during the unfolding of a pivotally mounted panel element 100 in detail views. Fig. 18G and Fig. 18H, the pivotally mounted panel elements 100 are shown unfolded by approximately 45° in a three-dimensional view and a top view, while the pivotally mounted panel elements 100 in the Fig. 18I to 18L are shown in corresponding illustrations in fully unfolded states, wherein Fig. 18I an exploded view of the Fig. is 18 years old.

[0090] The features and exemplary embodiments described in conjunction with the figures can be combined with one another according to further exemplary embodiments, even if not all combinations are explicitly described.
