The invention relates to a connecting component for connecting different scaffolding systems, comprising at least a first connection region, which is provided for connection to a first scaffolding system and which has a shaft that extends along a longitudinal axis, and an attachment region which is provided for connection to a second scaffolding system, wherein the first connection region and the attachment region are arranged adjacent to one another in the direction of the longitudinal axis and the first connection region has a receptacle in its interior in the shaft, at least on its side pointing away from the attachment region, which extends in the direction of the longitudinal axis. The attachment region has an abutment adjacent to the first connection region extending in a direction essentially perpendicular to the longitudinal axis, and the abutment has the longest dimension of the attachment region in the direction essentially perpendicular to the longitudinal axis. The attachment region also has an insertion region extending in the direction of the longitudinal axis and adjoining the abutment against the side of the abutment facing away from the first connection region in the direction of the longitudinal axis. The invention further relates to a scaffolding section for connecting different scaffolding systems with a connecting component.
Scaffolding is used in the construction sector for various tasks. Façade scaffolding is used to design the outer surfaces of buildings, for example to paint them. Façade scaffolding is usually constructed from façade scaffolding frames as the main components, and more recently they have also been constructed from modular scaffolding. In civil engineering, shoring is used to bring a wide variety of building components into position and hold them there. Such building parts can be, for example, prefabricated concrete parts, steel support members or steel structures. Furthermore, elements required for the erection of buildings, such as makeshift constructions or formwork, can be positioned with shoring. Finally, scaffolding is also used in the service or revision region, for example to bring workers safely to the parts of the plant to be overhauled in large processing plants such as refineries. In general, the basic requirements for scaffolding are that they must be easy to transport and set up.
Different scaffolding systems exist for different applications. Such scaffolding systems are constructed as a modular system and make it possible to assemble individual scaffolding shapes from standardized components in a simple manner. However, these components can usually only be efficiently combined with components from the same scaffolding system and can be connected to another scaffolding system only with great effort. For example, there are system scaffolds from civil engineering as construction aids for bridges, which are very able to take a load and are intended to temporarily support components of the bridge during construction. However, in order to allow workers to work on a bridge that is to be constructed, the construction aid for the bridge must also have steps, railings, ladders and the like. However, these elements are typically created using a different scaffolding system, such as façade scaffolding. In the example of erecting a bridge, the assembly aid or support structure of the bridge, which is formed by a first scaffolding system, must be connected to work surfaces for working people, which are formed by a second scaffolding system. In this case, interfaces must be provided that allow a second scaffolding system to be connected to a first scaffolding system. In the prior art, this is often realized by individually adapted connecting components that are created on site at the construction site. The disadvantage of such self-made connecting parts is that their load-bearing capacity is often not correctly estimated and, in addition, a high amount of work is required for the creation of such connecting parts. Another problem with such individually built connecting parts is that often a grid, which represents a basic dimension of a scaffolding system, cannot be maintained when installing such connecting parts. Because a connecting part does not fit the grid of a scaffolding system, the other parts of the modular system of the scaffolding system often cannot be connected to it as planned and further adaptation effort is required when erecting the scaffolding.
International patent application WO2019/161825A1 discloses a post connection adapter with which a vertical post of a first scaffolding system can be connected to a support member from another scaffolding system. The proposed adapter can be connected via a plurality of connecting elements to the support member, which has a plurality of connection holes. A disadvantage of the proposed solution is that such an adapter can only be connected to support members having a precisely defined width. In addition, the adapter only allows a second scaffolding system to be connected to a first scaffolding system on one side. If a connection is required on both sides, a plurality of adapters is required, which results in an increased workload and in most cases the grid dimension of a scaffolding system cannot be maintained with the adapter.
The object of the invention is therefore to propose solutions with which scaffolding elements of at least two different scaffolding systems can be securely connected to one another, this connection being provided to allow further construction of the at least two different scaffolding systems across the connection point with reduced adaptation effort.
This object is achieved by a connecting component for connecting different scaffolding systems, comprising at least a first connection region, which is provided for connection to a first scaffolding system and which has a shaft, which extends along a longitudinal axis, and an attachment region, which is provided for connection to a second scaffolding system, wherein the first connection region and the attachment region are arranged adjacent to one another in the direction of the longitudinal axis and the first connection region has a receptacle in its interior in the shaft, at least on its side pointing away from the attachment region, which receptacle extends in the direction of the longitudinal axis, and wherein the attachment region has an abutment adjacent to the first connection region which extends in a direction essentially perpendicular to the longitudinal axis and the abutment in the direction essentially perpendicular to the longitudinal axis has the longest dimension of the attachment region, and the attachment region also has an insertion region which extends in the direction of the longitudinal axis and which, in the direction of the longitudinal axis, adjoins the abutment on the side of the abutment facing away from the first connection region, wherein the insertion region has at least one first insertion interface, which has two first abutment surfaces that are parallel to each other and/or are oriented symmetrically with respect to the longitudinal axis, which abutment surfaces are arranged in the radial direction to the longitudinal axis on the outside of the insertion region and are oriented parallel to the longitudinal axis, and the first insertion interface comprises at least one securing recess penetrating the entire insertion region and extending essentially at a right angle to the two first abutment surfaces, wherein the abutment projects in a first direction radially with respect to the longitudinal axis, which has the longest dimension of the attachment region, further over the longitudinal axis than in a second direction that is radial to the longitudinal axis and essentially perpendicular to the first direction.
A connecting component according to the invention is used to connect two different scaffolding systems. For this purpose, the connecting component has an interface for connection to a first scaffolding system and an interface for connection to a second scaffolding system. These interfaces allow the connecting component to be connected quickly, easily and securely to both scaffolding systems. The connecting component comprises at least a first connection region, which forms the interface to a first scaffolding system. The connection region has a shaft extending along a longitudinal axis. In most cases, this longitudinal axis corresponds to an assembly direction of the first scaffolding system. The longitudinal axis is preferably arranged symmetrically with respect to the shaft. In the following, this longitudinal axis serves as a geometric basis for describing further elements and relationships between these elements. The shaft is preferably designed to be cylindrical. However, other cross-sectional shapes, for example a square cross-section, of the shaft are also conceivable. As an interface to a second scaffolding system, the connecting component includes an attachment region. The first connection region and the attachment region are arranged adjacent to one another in the direction of the longitudinal axis and bordering one another. The interfaces of the connecting component to the first scaffolding to the first and to the second scaffolding system are thus arranged directly adjacent to one another. The first connection region has, in its shaft, at the end facing away from the attachment region, a receptacle in its interior. This receptacle extends along the longitudinal axis. The receptacle is provided so that, when the connecting component is connected to an element of a first scaffolding system, at least a partial region of this element can be inserted into the receptacle. This creates a positive lock between the connecting component and the first scaffolding system, which allows the connecting component and the first scaffolding system to be assembled easily and securely. The receptacle preferably has a circular cross section and extends linearly along the longitudinal axis. The interior of the receptacle is therefore preferably designed to be cylindrical. The shape and size of the receptacle corresponds to the shape and size of receptacles that are used in the first scaffolding system to connect a plurality of scaffolding elements of the same modular system to each other. Various elements of the first scaffolding system can thus be connected in a simple manner to the receptacle of the first connection region of the connecting component. The receptacle can extend along the longitudinal axis through the entire shaft or only through part of the shaft. The attachment region includes an abutment which is arranged directly adjacent to the first connection region. This abutment extends in a direction that is essentially perpendicular to the longitudinal axis and is provided as an abutment for the connecting component on an element of a second scaffolding system. The abutment serves both as a positioning aid and for the transmission of force and torque between the connecting component and the second scaffolding system. An extension of the abutment perpendicular to the longitudinal axis means that the longest dimension of the abutment, its length, is oriented perpendicularly to the longitudinal axis. The thickness of the abutment is preferably oriented parallel to the longitudinal axis. A width of the abutment runs perpendicular to the longitudinal axis and length of the abutment. The abutment advantageously has a plate-shaped design. The longest dimension of the attachment region in the radial direction to the longitudinal axis is in the abutment. In other directions, for example parallel to the longitudinal axis, other elements of the attachment region can have longer dimensions than the largest dimensions of the abutment. The shaft of the first connection region and the abutment merge into one another abruptly, i.e., the outer surface of the shaft is oriented at a right angle to the surface of the abutment that is oriented in the direction of the first connection region. In a top view of the abutment from the direction of the longitudinal axis, said abutment preferably has a rectangular shape, the length of the abutment being greater than its width. With its length, the abutment has the longest dimension of the attachment region. This means that the abutment projects over the other partial regions of the attachment region. Another such partial region of the attachment region is the insertion region, which extends adjacent to the abutment on the side of the abutment facing away from the first connection region. The insertion region is intended to be inserted into an element or between two elements of the second scaffolding system. The insertion region comprises at least one first insertion interface, which is shaped in such a way that it can at least partially form a positive lock with the second scaffolding system. The first insertion interface includes two first abutment surfaces, which are arranged parallel to one another and/or symmetrically with respect to the longitudinal axis. The abutment surfaces can be flat or curved. The two first abutment surfaces form outer surfaces of the insertion region and are arranged on its outer circumference. The first abutment surfaces are arranged at a distance from the longitudinal axis in the radial direction relative to the longitudinal axis. In their longest extent, the abutment surfaces run parallel to the longitudinal axis. This means that the longest extension or dimension of the two abutment surfaces is oriented parallel to the longitudinal axis. The two first abutment surfaces can be fixedly arranged on the attachment region. Alternatively, the position of the two first abutment surfaces relative to the longitudinal axis can also be adjustable. The distance between the two first abutment surfaces can then also be adjusted and can thus be easily adapted to different second scaffolding systems. For the positive-locking connection of the attachment region to the second scaffolding system, the insertion region also includes a securing recess which penetrates the entire insertion region and which is arranged essentially at a right angle to the two first abutment surfaces. When connecting the connecting component to the second scaffolding system, a pinning element or staking element can be introduced into the securing recess, which is additionally introduced into a receiving recess in the second scaffolding system. In this way, a positive-locking connection can be produced between the connecting component and the second scaffolding system by staking. Such a staking between two components to be connected to each other is also used within many scaffolding systems between elements of the same modular system. Such a connection is easy to make and stable.
The abutment of the connecting component according to the invention can project further over the adjacent insertion region in a first direction radially to the longitudinal axis than in a second direction, which also runs radially to the longitudinal axis and at the same time essentially perpendicular to the first direction. This means that the abutment can project further over the longitudinal axis in a partial region in the circumferential direction than in another partial region. The projection of the abutment over the longitudinal axis can thus be unequally large in the circumferential direction around the longitudinal axis. The abutment preferably projects furthest over the longitudinal axis in a first radial direction relative to the longitudinal axis, which corresponds to the radial direction relative to the longitudinal axis, which is oriented perpendicularly to the two first abutment surfaces. In this way it can be achieved that the abutment rests securely on a scaffolding element of the second scaffolding system when the first insertion interface with the two first abutment surfaces are arranged within this scaffolding element of the second scaffolding system. In addition, this uneven projection of the abutment over the longitudinal axis means that in partial regions, outside the first abutment surfaces, the abutment projects less far over the insertion interface, where it is usually not necessary to place the abutment on a scaffolding element of the second scaffolding system. This design of the abutment means that the connecting component has an optimally low weight.
In addition, the abutment projects further over the longitudinal axis in a first direction radial to the longitudinal axis, which has the longest dimension of the attachment region radial to the longitudinal axis, than in a second direction radial to the longitudinal axis and essentially perpendicular to the first direction. In a top view from the direction of the longitudinal axis, the abutment therefore does not project to the same extent overall in the circumferential direction. This design ensures that the connecting component has a shape that is optimally integrated into the second scaffolding system and does not project over its scaffolding elements in a direction radial to the longitudinal axis.
The connecting component according to the invention has the advantage that it can be connected to two different scaffolding systems very easily and without any individual adaptation effort. A first scaffolding system can be easily connected to the receptacle in the first connection region via an insertable coupling. This connection via the receptacle essentially corresponds to other connections used between different scaffolding elements of the first scaffolding system. The first connection region is thus integrated into the first scaffolding system and fully compatible with other scaffolding elements from the modular system of the first scaffolding system. The same applies to the insertion interface and the second scaffolding system: the shape and dimensions of the insertion interface correspond to an interface which is essentially also used between scaffolding elements of the second scaffolding system. In this way, the insertion interface or the attachment region can be integrated directly into a second scaffolding system without any adaptation effort. The arrangement, according to the invention, of the first connection region and fastening region covers a large number of cases in which the two scaffolding systems have to be connected to one another. The connecting component according to the invention can thus be used as a standard connection between the two scaffolding systems. The connection to the second scaffolding system can also be made and secured in a simple manner by means of an insertable coupling by providing the securing recess. This allows a scaffolding section to be erected quickly and safely, which scaffolding section has scaffolding elements of the first scaffolding system and of the second scaffolding system. The use of the connecting component according to the invention for connecting two scaffolding systems can thus save time for the assembly of the relevant scaffolding section. A further advantage of a connecting component according to the invention is that the first connection region and the attachment region can be dimensioned in such a way that they correspond to the grid of the first scaffolding system and the second scaffolding system. As a result, both the first scaffolding system and the second scaffolding system can continue to be built in the relevant grid used by this scaffolding system. In this way, the performance of both scaffolding systems can be fully maintained across the connection point. Due to the simple structure, the connecting component according to the invention is robust and at the same time has a low dead weight. This allows it to be easily transported and attached to a scaffolding section.
In one embodiment, it is provided that the connecting component also has a second connection region which is provided for connection to a first scaffolding system and the second connection region is arranged in the direction of the longitudinal axis on the side of the abutment opposite the first connection region, the second connection region having a receptacle which extends along the longitudinal axis, the internal cross section of the receptacle oriented perpendicular to the longitudinal axis having a shape which is essentially identical to the shape of the internal cross section of the receptacle of the first connection region in a plane perpendicular to the longitudinal axis. In this embodiment, the connecting component comprises two connection regions, which are provided as interfaces for connection to the first scaffolding system. The second connection region is arranged opposite the first connection region in the direction of the longitudinal axis. The second connection region is located on the opposite side of the abutment from the first connection region. The second connection region can extend partially in the attachment region or be arranged adjacent to the attachment region on the side opposite the first connection region. The second connection region also includes a receptacle into which scaffolding elements of the first scaffolding system can be inserted. The receptacle of the second connection region is preferably designed identically to the receptacle in the first connection region. In particular, the cross-sectional region of the receptacle in a direction perpendicular to the longitudinal axis is identical. In this embodiment, the distance between the ends of the first connection region and the second connection region can be selected such that this distance corresponds to a grid dimension of the first scaffolding system. In this way, the grid of the first scaffolding system is retained when the connecting component is installed between the scaffolding element of the first scaffolding system. In this embodiment, scaffolding elements of the first scaffolding system can be connected on both sides of the attachment region. In this embodiment, a junction between the first scaffolding system and the second scaffolding system, which is connected to the attachment region, can thus be produced in a simple manner. The second connection region can include a second shaft, which contains the receptacle and which is designed the same as or similar to the shaft of the first connection region. Such a shaft can be formed, for example, by a tube section of a cylindrical tube.
In a further embodiment, it is provided that the insertion region of the attachment region also has a second insertion interface, which has two second abutment surfaces oriented parallel to one another and/or symmetrically with respect to the longitudinal axis which are arranged on the outside of the insertion region in the radial direction relative to the longitudinal axis and are oriented parallel to the longitudinal axis, and the second insertion interface comprises at least one securing recess penetrating the entire insertion region and extending essentially at a right angle to the two second abutment surfaces and the two second abutment surfaces are oriented at an angle, in particular at a right angle, to the two first abutment surfaces. In this embodiment, the insertion region of the attachment region comprises two differently dimensioned insertion interfaces. These two different insertion interfaces make it possible to connect the connecting component to differently dimensioned scaffolding elements of the second scaffolding system. The first insertion interface is provided for connection to a first type of scaffolding element of the second scaffolding system and the second insertion interface is provided for connection to a second type of scaffolding element of the second scaffolding system. The two insertion interfaces are identical in principle, but differ from each other in details with regard to shape and dimensions. These details are described in further embodiments. The two second abutment surfaces are offset in the circumferential direction about the longitudinal axis relative to the two first abutment surfaces. The second abutment surfaces are thus arranged at an angle to the first abutment surfaces. The normals to the second abutment surfaces are thus also arranged at an angle to the normals to the first abutment surfaces. This angle between the first abutment surfaces and the second abutment surfaces is preferably 90°. In this embodiment, the first insertion interface is offset at a right angle in the circumferential direction about the longitudinal axis relative to the second insertion interface. The first insertion interface is used to connect the connection region to a scaffolding element of the first type of the second scaffolding system. If the connecting component is to be connected to a scaffolding element of the second type of the second scaffolding system, the connecting component is simply rotated 90° about the longitudinal axis and the second insertion interface is used to connect to the second scaffolding system. In this embodiment, it is thus possible by a simple rotation of the connecting component to establish a connection to a first type or to a second type of the second scaffolding system. Adaptation work is not required when changing the connection from the first type to the second type. This embodiment of the connecting component can thus be connected directly and without additional work to two different types of scaffolding elements via the attachment region. The provision of the second insertion interface thus further increases the range of uses of the connecting component. In addition, the second insertion interface also causes an increase in the stability of the attachment region, so that the connecting component can accept and sustain a higher load. The two insertion interfaces are preferably shaped symmetrically with respect to the longitudinal axis, so that the connecting component remains fully integrated when using both insertion interfaces in the grid of the second scaffolding system and the grid of the first scaffolding system. Due to the basically identical design of the two insertion interfaces, the work steps involved in connecting the connecting component to the second scaffolding system are almost identical for both insertion interfaces, so that the connecting component can be easily and safely assembled and disassembled by the working personnel.
In an advantageous embodiment, it is provided that the receptacle of the second connection region is positioned coaxially to the longitudinal axis and is thus aligned with the receptacle of the shaft of the first connection region, the receptacle having an end face hole and the receptacle having an end face hole, and the end face hole and the end face hole are arranged on opposite sides of the connecting component. In this embodiment, the two connection regions are arranged coaxial to one another. The two connection regions are thus in a common line of action for forces to be transmitted. In this embodiment, the two connection regions are arranged just as connection regions are arranged in relation to one another in a vertical post of a first scaffolding system. In this way, the connecting component behaves like a vertical post of the first scaffolding system and can therefore be integrated particularly easily into the first scaffolding system. Elements of the first scaffolding system can be inserted into the connecting component through the end face holes, which are arranged on the opposite sides of the two receptacles.
It is expediently provided that the second connection region is arranged within the attachment region. In this embodiment, the second connection region is arranged in the interior of or surrounded by the attachment region. This results in a compact arrangement of the interfaces to two scaffolding systems with a small overall length of the connecting component.
Alternatively, it is provided that the second connection region projects over the attachment region in the direction of the longitudinal axis on the side of the attachment region opposite the first connection region. In this embodiment, the second connection region projects over the attachment region on the opposite side of the connecting member to the first connection region. A part of the second connection region can also be arranged within the attachment region. This protrusion of the second connection region allows the overall length of the connecting component to be increased, for example in order to adapt the connecting component to a longer grid dimension of a first scaffolding system. In addition, the second connection region is easier to access if it projects over the attachment region.
In a further preferred embodiment, it is provided that the second connection region has a shaft which projects over the attachment region, at least in regions opposite the first connection region, the receptacle being arranged at least in some regions in the shaft. In this embodiment, the second connection region also has a shaft which is designed similarly or identically to the shaft of the first connection region. The receptacle of the second connection region can be arranged completely or only partially in the shaft.
Furthermore, it is provided that the first connection region and/or the second connection region has at least one staking hole, which extends radially to the longitudinal axis and which penetrates the entire first connection region and/or the entire second connection region. In this embodiment, a staking hole is provided in one or in two connection regions, which hole is preferably arranged in the shaft. A pinning element or staking element can be introduced into this staking hole in order to connect the connecting component and an adjacent scaffolding element of the first scaffolding system to one another in a positive-locking manner. Such staking is also used in many scaffolding systems to connect the same or different scaffolding elements within the scaffolding system. The staking hole in the connection region thus forms a further connection interface between the connecting component and the first scaffolding system and increases the security of the connection between the elements.
Furthermore, it is advantageously provided that the receptacle of the first connection region and/or the receptacle of the second connection region has/have a circular internal cross section perpendicular to the longitudinal axis. In this embodiment, the receptacle in the first and/or second connection region is of cylindrical design. This embodiment fits first scaffolding systems that have cylindrically dimensioned interfaces. Of course, the cross section of the receptacle can also have a different shape that matches the interfaces of the first scaffolding system.
It is expediently provided that the first connection region and/or the second connection region is/are formed by a tube, at least in some regions. In this embodiment, the connection region is formed by a tubular section. In addition to the tubular section, the connection region can also have other components. This embodiment is particularly easy to manufacture.
Furthermore, it is provided that the abutment closes up the receptacle in the first connection region in the axial direction along the longitudinal axis or at least reduces its inner diameter. In this embodiment, the abutment is designed in such a way that it at least partially narrows the inner diameter. The abutment projects into the interior of the receptacle. A scaffolding element of the first scaffolding system, which is pushed into the receptacle, can thus rest on the abutment in the axial direction parallel to the longitudinal axis. As a result, forces can be transferred from the introduced scaffolding element to the connecting component. Alternatively, it is also possible for the receptacle in the first connection region and any receptacle that may be present in a second connection region to transition into one another without narrowing in their interior. In this alternative case, the abutment does not project inside the receptacle. This makes it possible to guide elements completely through the receptacle and through the entire connecting part along the longitudinal axis. In this case, forces can be supported and transmitted via the end of the connection region facing away from the abutment. As described above, it is also possible to provide a first connection region and a second connection region, both of which are formed together by a common, continuous tube section which is not narrowed in its interior by the abutment. In this case, the abutment is designed in such a way that it is located completely outside the tubular section and is firmly connected to it on its outer surface.
It is advantageously provided that the first connection region has a connecting disk which is fastened to an outer surface of the shaft, the connecting disk extending in the radial direction in relation to the longitudinal axis and the connecting disk having at least one planar connection surface which is oriented essentially at a right angle to the longitudinal axis and wherein at least one connection recess is made in the connection surface that completely penetrates the connection disk parallel to the longitudinal axis. In this embodiment, a connecting disk is arranged on the outside of the shaft and is used to connect the first and/or second connection region to scaffolding elements of the first scaffolding system. The connecting disk extends radially away from the longitudinal axis. In a top view in the direction of the longitudinal axis, the connecting disk can have an outer shape that is round, square, rosette-shaped or shaped in some other way. The connecting disk has a flat connection surface which is oriented at a right angle to the longitudinal axis. A plurality of connection recesses are preferably arranged in the connection surface, through which recesses interfaces of scaffolding elements of the first scaffolding system can be guided. Such connecting disks are also used on other scaffolding elements of the first scaffolding system, for example on vertical posts. The connection recess or the connection recesses can be adapted in shape to interfaces of the relevant first scaffolding system.
It is expediently provided that the abutment of the attachment region projects in the radial direction to the longitudinal axis over the first connection region. In this embodiment, the abutment projects over the connection region, at least at the point at which the abutment is connected to the first attachment region. This results in a sudden transition between the connection region and the attachment region to which the abutment belongs. However, this transition can also have a chamfer or a radius, which make the transition between the connection region and the attachment region less abrupt and thereby reduce the occurrence of notch effects. If the connection region has a connecting disk, this can also project past the abutment in the radial direction to the longitudinal axis.
In an advantageous embodiment, it is provided that the outer diameter of the insertion region in the radial direction to the longitudinal axis is greater than the inner diameter of the receptacle of the first connection region and/or is greater than the inner diameter of the receptacle of the second connection region. In this embodiment, the outer peripheral surface of the insertion region projects radially further over the longitudinal axis than the inner diameter of the receptacle. The insertion region is intended to be inserted into a scaffolding element or between two scaffolding elements of the second scaffolding system. Due to the fact that the inner diameter of the receptacle, which is provided for receiving a scaffolding element of the first scaffolding system, is smaller than the outer diameter of the insertion region, scaffolding elements of the first scaffolding system can be guided through the connecting component and thus through crossing scaffolding elements of the second scaffolding system. This embodiment is particularly advantageous, because the two scaffolding systems can both be continuously connected to one another in their grid with the aid of the connecting component. In this way, a joining of the two scaffolding systems can essentially be carried out in the same way and is just as stable as if the two scaffolding systems each continued to be constructed individually in their respective grids.
Furthermore, it is expediently provided that the abutment is composed of a plurality of components and in some regions of a cover plate oriented essentially at a right angle to the longitudinal axis and in some regions through a partial region of at least one insertion plate oriented parallel to the longitudinal axis, the insertion plate also providing at least one part of the first abutment surfaces. In this embodiment, the abutment comprises a plurality of partial regions which are formed by different, but interconnected components of the attachment region. The abutment comprises a cover plate, which projects in the radial direction to the longitudinal axis over the first connection region connected thereto. At least one insertion plate is arranged directly adjacent to and connected to the cover plate, a partial region of which belongs to the abutment. Another partial region of the insertion plate belongs to the insertion region and provides at least one of the first abutment surfaces. The partial region of the insertion plate belonging to the insertion region is inserted into a scaffolding element or between two scaffolding elements of this second scaffolding system when connecting to the second scaffolding system. The region of the insertion plate that belongs to the abutment is not inserted into the second scaffolding system, but can serve as a bearing surface when the connecting component is positioned relative to the second scaffolding system.
It is advantageously provided that the abutment has a planar first bearing surface which is oriented essentially at a right angle to the longitudinal axis and projects in the radial direction with respect to the longitudinal axis over the two first abutment surfaces. In this embodiment, the abutment comprises a first bearing surface, which is arranged on its side facing away from the first connection region. The bearing surface is oriented at a right angle to the longitudinal axis and projects in the radial direction over the two first abutment surfaces. The first bearing surface is intended to rest on a scaffolding element of the second scaffolding system in a case in which the two first abutment surfaces are inserted into a scaffolding element or between two scaffolding elements of the second scaffolding system. In this case, the two first abutment surfaces rest on the inside of the second scaffolding system, and the first bearing surface defines the assembly position or connection position between the second scaffolding system and the connecting component.
In an advantageous embodiment, it is provided that the first bearing surface is arranged on the cover plate or at least an insertion plate. The first bearing surface can be arranged either on the side of the cover plate facing away from the first connection region or on a surface of an insertion plate facing away from the first connection region. In a case in which a plurality of insertion plates, which in particular are arranged parallel to one another, are provided, the first bearing surface can also be composed of surfaces of a plurality of insertion plates.
Furthermore, it is provided that the first bearing surface and the two first abutment surfaces are arranged bordering one another and/or directly adjoin one another. In this embodiment, the first bearing surface and the two first abutment surfaces are arranged directly adjacent to one another. In particular, these two surfaces are arranged at right angles to one another. This arrangement, in which they are directly adjacent to one another, allows a particularly stable connection to a scaffolding element of the second scaffolding system. This scaffolding element of the second scaffolding system usually has two surface regions which are also adjacent to one another and are positioned at right angles to one another. The described design of the first bearing surface and first abutment surfaces thus allows an optimal positive lock between the attachment region and the scaffolding element of the second scaffolding system.
In one embodiment it is provided that two insertion plates are provided which are oriented parallel to one another and are arranged symmetrically with respect to the longitudinal axis. In this embodiment, the attachment region includes two insertion plates. These two insertion plates are arranged symmetrically with respect to the longitudinal axis. If a partial region of a second connection region runs inside the attachment region, the two insertion plates can be connected thereto or attached thereto. The two insertion plates are preferably identical to one another in terms of shape and dimensions.
In a further embodiment, it is provided that the insertion plate has a mounting surface which is oriented essentially at a right angle to a normal to the longitudinal axis and has an edge region oriented at a right angle to the mounting surface and surrounding the insertion plate, and partial regions of the two first abutment surfaces are arranged on mutually opposite partial regions of the edge region. In this embodiment, the insertion plate includes a mounting surface which is planar or curved. This mounting surface is oriented perpendicular to the direction normal to the longitudinal axis. The mounting surface is arranged on the side of the insertion plate which is inwardly oriented in the direction of the longitudinal axis. The mounting surface is preferably designed to be planar. An edge region surrounds the insertion plate adjacent to the mounting surface. This edge region is preferably formed by surfaces which are oriented at right angles to the mounting surface. Parts of this edge region form parts of the first abutment surfaces. In this case, a part of a first abutment surface is formed by a first partial region of the edge region. A part of a second first abutment surface is formed by the second partial region of the edge region, which is opposite the first partial region of the edge region.
It is expediently provided that the first bearing surface is arranged on the edge region adjacent to a partial region of the two first abutment surfaces. In this embodiment, both the first bearing surface and a partial region of the two first abutment surfaces are arranged on the edge region of the insertion plate. The first abutment surfaces and the first bearing surface are adjacent and preferably arranged at right angles to one another.
In one embodiment it is provided that two insertion plates are provided and parts of the edge regions of both insertion plates together form the first bearing surface and the two first abutment surfaces. In this embodiment, two insertion plates are provided which are arranged symmetrically with respect to the longitudinal axis and together form both the first bearing surface and the two first abutment surfaces. This embodiment is particularly stable. Partial regions of the two first abutment surfaces are arranged at a distance from one another, which is favorable for the transmission of force and torque between the connecting component and the second scaffolding system. In addition, the provision of two insertion plates simplifies the arrangement of a second insertion interface with second abutment surfaces. For this purpose, a further embodiment is described below.
Furthermore, it is advantageously provided that the securing recess is arranged in a partial region of the attachment region that is different from the insertion plate. In this embodiment, the securing recess does not run through an insertion plate. The securing recess can run, for example, in a partial region of the third connection region, which is arranged within the attachment region. The securing recess can also be arranged in a further component of the attachment region. In a case wherein two insertion plates are provided, the securing recess is preferably provided between the two insertion plates and crosses the longitudinal axis.
It is expediently provided that a plurality of securing recesses are provided spaced apart from one another in the direction of the longitudinal axis. In this embodiment, a plurality of securing recesses are provided in the direction of the longitudinal axis and can be used simultaneously or as alternative selections for staking the connecting component to one or more scaffolding elements of the second scaffolding system. By providing a plurality of securing recesses, the connecting component can be connected to differently dimensioned scaffolding elements of the second scaffolding system without the need for adaptation work. The load capacity of the connection can be increased if a plurality of securing recesses are used at the same time for the staking.
Furthermore, it is expediently provided that the insertion region of the attachment region has a second insertion interface, the second abutment surfaces of which are each arranged on an insertion plate, the abutment surfaces being formed by outer surfaces, which are each oriented parallel to a mounting surface. In this embodiment, the attachment region comprises two insertion interfaces, which are alternatives that can be selected for connecting to a scaffolding element of a second scaffolding system. Each of these two insertion interfaces has two abutment surfaces. The two second abutment surfaces of the second insertion interface are each arranged on one of two insertion plates. The abutment surfaces are each formed by surfaces that represent the outer surfaces of the corresponding insertion plate. These outer surfaces are arranged parallel to the corresponding mounting surface of each insertion plate. In this embodiment, the edge regions of the two insertion plates together form the two first abutment surfaces, and one outer surface of each insertion plate alone forms one of the two second abutment surfaces. In this embodiment, all abutment surfaces of the two insertion interfaces are skillfully arranged on the two insertion plates. A connecting component designed in this way is therefore formed by only a few components and is therefore simple in construction, compact and has a low weight. Nevertheless, this embodiment has two different insertion interfaces, which can be flexibly connected to differently dimensioned scaffolding elements of a second scaffolding system.
It is expediently provided that the abutment has a planar second bearing surface which is oriented essentially at a right angle to the longitudinal axis and projects in the radial direction with respect to the longitudinal axis over the two second abutment surfaces. In this embodiment, the second insertion interface is assigned its own second bearing surface on the abutment. In order to act as an abutment in the connection between the connecting component and one or more scaffolding elements of a second scaffolding system, the second bearing surface projects over the second abutment surfaces in the radial direction relative to the longitudinal axis. In this case, the second bearing surface can also be formed by two partial surfaces which are arranged separately from one another and each adjacent to one of the two abutment surfaces. The second bearing surface and the two second abutment surfaces are preferably oriented at right angles to one another. The first bearing surface and the second bearing surface can be arranged in the same plane or in different planes arranged parallel to one another.
In an advantageous embodiment it is provided that the second bearing surface is formed by a surface of the cover plate and the second bearing surface is adjacent to the two second abutment surfaces. In this embodiment, the second bearing surface is a partial surface of the cover plate, which is arranged on the side of the cover plate facing away from the connection region. The second bearing surface can be divided in two and formed by two separate partial surfaces of the cover plate. The second bearing surface is directly adjacent to the two second abutment surfaces. The second bearing surface is preferably oriented at a right angle to the second abutment surfaces. The second bearing surface can project over the two second abutment surfaces to the same extent that the first bearing surface projects over the two first abutment surfaces. Alternatively, the projection of the second bearing surface over the second abutment surfaces can also be designed differently from the projection of the first bearing surface over the first abutment surfaces.
It is expediently provided that the securing recess penetrates at least one insertion plate. The second insertion interface also has a securing recess which penetrates the entire insertion region. A pinning element for securing and attaching the connecting component to a scaffolding element of the second scaffolding system can be introduced into this securing recess. The securing recess of the second insertion interface is designed analogously to the securing recess of the first insertion interface. Starting from at least one second abutment surface, the securing recess extends in the radial direction through the insertion region. The securing recess penetrates at least one insertion plate. In an embodiment in which two insertion plates are provided, the securing recess preferably penetrates through both insertion plates.
Provision is advantageously made for a plurality of securing recesses to be provided spaced apart from one another in the direction of the longitudinal axis. In this embodiment, a plurality of securing recesses are also provided on or in the second insertion interface. As a result, the connecting component can also be connected to differently designed scaffolding elements of the second scaffolding system using the second insertion interface, without the need for adaptation work.
Furthermore, it is provided that the distance between the two first abutment surfaces differs from the distance between the two second abutment surfaces. The distance between the two first abutment surfaces preferably differs from the distance between the two second abutment surfaces. The dimensions of the two insertion interfaces thus differ from one another, as a result of which the connecting component can be connected to differently dimensioned scaffolding elements of the second scaffolding system via the two insertion interfaces. Depending on which scaffolding element of the second scaffolding system the connecting component is to be connected to, either the first insertion interface or the second insertion interface is used for this connection.
The object of the invention is also achieved by a scaffolding section for connecting different scaffolding systems, comprising at least one connecting component according to any of the embodiments described above, at least one scaffolding element of a first scaffolding system which is connected to the first connection region and/or the second connection region of the connecting component in a positive-locking manner, and at least one scaffolding element of a second scaffolding system, which is connected to the attachment region of the connecting component in a positive-locking manner, the first scaffolding system and the second scaffolding system differing from one another. A scaffolding section according to the invention comprises at least one connecting component. This connecting component is connected in the scaffolding section to a first scaffolding system and a second scaffolding system. The first scaffolding system is connected in a positive-locking manner, for example by insertion, to the first connection region of the connecting component. If the connecting component has a second connection region, a further scaffolding element of the first scaffolding system can also be connected to the second connection region. The positive-locking connection between the first scaffolding system and the connection region can be additionally reinforced and secured by staking with a pinning element. The pinning element is then used to create a further positive lock between the connecting component and the first scaffolding system. The scaffolding section according to the invention also comprises at least one scaffolding element of a second scaffolding system, which is connected to the attachment region of the connecting component in a positive-locking manner. This connection can also be reinforced and secured by staking it using the securing recess. The first and second scaffolding systems are different from each other and have different connection interfaces. In the scaffolding section according to the invention, the connecting component acts as an adapter between the two different scaffolding systems. Because the connecting component has both an interface for connection to the first scaffolding system and an interface for connection to the second scaffolding system, a connection between the two scaffolding systems is possible in a simple manner and without any adaptation effort. A scaffolding section according to the invention can thus be erected and dismantled again simply and quickly. The connecting component is dimensioned in such a way that when two different scaffolding systems are connected, the grid of the two scaffolding systems is retained across the connection point. As a result, the scaffolding section is integrated into both scaffolding systems and the advantages of both scaffolding systems are retained despite the connection point.
In one embodiment it is provided that the scaffolding element of the first scaffolding system is formed by a vertical post of a frame scaffolding or system scaffolding and the scaffolding element of the second scaffolding system is formed by a horizontal support, the horizontal support comprising two spaced-apart, parallel-aligned support rails. In this embodiment of the scaffolding section, the scaffolding element of the first scaffolding system which is connected to the connection region is a vertical post. Such vertical posts are used in scaffolding systems of frame scaffolding or system scaffolding. Such a vertical post is usually oriented vertically in a scaffolding section.
In this embodiment, the scaffolding element of the second scaffolding system is formed by a horizontal support that is usually oriented horizontally. This horizontal support is designed to accommodate loads and is part of a scaffolding system that is used primarily in civil engineering. Such a horizontal support can be provided, for example, to support and position prefabricated parts of a building structure. In this case, the horizontal support comprises two support rails which are spaced apart from one another and run parallel to one another. The two support rails are connected to each other at a plurality of points and thus form the horizontal support. The two support rails usually have an I, C or T-shaped cross section, which is particularly favorable for achieving high flexural strength.
It is expediently provided that the vertical post is inserted into the receptacle of the first connection region or the receptacle of the second connection region. The vertical post of the first scaffolding system is inserted in the scaffolding section into the receptacle of a connection region. The receptacle can at least partially correspond to the negative shape of one end of a vertical post. Alternatively, the vertical post can be inserted into the receptacle with an adapter piece interposed.
In a further embodiment, it is provided that an adapter piece is arranged between the vertical post and the receptacle of the first connection region or the receptacle of the second connection region which connects the vertical post and the connecting component to one another. In this embodiment, an adapter piece is arranged between the vertical post and the receptacle. On the one hand, this adapter piece is inserted into the receptacle of the connecting component and, on the other hand, is inserted into an end face of a vertical post. Such an adapter piece makes it possible to connect a connecting component and a vertical post to one another, both of which have a hollow recess as an interface. Forces can be transmitted between the vertical post and the connecting component through the adapter piece. Alternatively, force can also be transmitted directly between the connection region of the connecting component and the end face of the vertical post. In some regions, the adapter piece has a negative shape of the recess of the connection region and in some regions a negative shape of the interior of the end face of the vertical post. The adapter piece can be provided in different lengths, which provides an additional possibility of easily adapting the grid dimension of the connecting component to the first scaffolding system.
Furthermore, it is advantageously provided that the insertion region of the connecting component is arranged between the support rails of the horizontal support and the two first abutment surfaces, or the two second abutment surfaces of the insertion region bear against inner surfaces of the support rails. In this embodiment of the scaffolding section, the insertion region is at least partially inserted between the support rails of the horizontal support. The abutment rests on the support rails. The distance between the abutment surfaces essentially corresponds to the distance between the two support rails of the horizontal support. In this way, a positive lock is established between the insertion region and the horizontal support. The two abutment surfaces of the first insertion interface or the second insertion interface rest against inner surfaces of the support rails that face one another. Of course, a small distance can be provided as play between the abutment surfaces and the inner surfaces of the support rails, through which space the insertion region can be inserted between the two support rails. By arranging the attachment region of the connecting component between the two support rails, a particularly stable and secure connection between the connecting component and the second scaffolding system is made possible. The connection is located within the horizontal support and thus does not prevent the attachment of other elements or components on the outside of the horizontal support. Furthermore, this connection inside the horizontal support reduces the risk of injury for people working on the scaffolding section from projecting scaffolding components.
Furthermore, it is provided that the support rail has a receiving recess which penetrates the support rail in a direction perpendicular to its longitudinal direction, the connecting component being oriented to the horizontal support such that the securing recess is aligned with the receiving recesses in the support rails. In this embodiment, at least one receiving recess is placed in each of the two support rails of the horizontal support. This receiving recess penetrates the support rail completely and has a shape and size which essentially corresponds to the shape and size of the securing recess of the connecting component. When connecting the connecting component to the horizontal support, the attachment region is inserted between the two support rails, so that the securing recess and the receiving recess are aligned. A plurality of receiving recesses are preferably arranged in each support rail. For example, a plurality of receiving recesses can be arranged at a distance from one another in the longitudinal direction. This makes it possible to connect the connecting component to the horizontal support at different points.
Furthermore, it is advantageously provided that a staking element is provided which is releasably introduced into the securing recess and the receiving recesses in a positive-locking manner and which connects the horizontal support and the connecting component in a positive-locking manner. In this embodiment of a scaffolding section, a staking element is provided for fixing the connecting component and horizontal support to one another. This staking element can be cylindrical, at least in some regions, and is always dimensioned in such a way that it can be inserted into the securing recess and the receiving recesses. To fix the connecting component, it is inserted between the support rails, so that the securing recess and the receiving recesses are aligned with one another. Then the staking element is inserted into the aligned recesses. This staking is done from outside the horizontal support and is therefore easy to carry out. In addition, it can be clearly recognized from outside the horizontal support whether or not a staking element has been introduced. This is useful for checking that the scaffolding section is set up correctly before people enter the scaffolding.
It is expediently provided that the staking element has a clamping device and the clamping device generates a force for the additional, non-positive connection between the horizontal support and the connecting component. In this embodiment, a clamping device is provided on the staking element by means of which an outer dimension of the staking element can be changed in its radial direction. This clamping device is used to secure the staking element when it is inserted. The staking element is inserted into the connection between the horizontal support and the connecting component and the clamping device is then actuated. As a result, the outer diameter of the staking element is increased in some regions, so that it is pressed against the inner wall of the recesses. This creates a non-positive connection between the components and prevents the staking element from falling out. Alternatively, the staking element can also have a clamping device acting in its axial direction, for example formed by a simple external thread onto which a nut is screwed in the inserted state. Furthermore, it is possible to provide, instead of a tensioning device, a locking pin which penetrates the staking element in the introduced state and then projects over the staking element. In this way, too, the staking element cannot unintentionally fall out of the recesses.
Furthermore, it is advantageously provided that at least two spacers are introduced between the support rails, which spacers position the two support rails relative to one another. In this embodiment, the two support rails of the horizontal support are connected by at least two spacers. The distance between the first abutment surfaces or the second abutment surfaces of the connecting component is selected to be slightly smaller than the inner distance between the two support rails set by the spacers.
Furthermore, it is advantageously provided the overall length of the connecting component corresponds to a grid dimension of the first scaffolding system and/or the distance between the two parallel first abutment surfaces and/or the two parallel second abutment surfaces corresponds to a grid dimension of the second scaffolding system. The overall length of the connecting component along the longitudinal axis is set such that this length corresponds to a grid dimension of the first scaffolding system. In addition, the distance between the abutment surfaces is matched to the distance between the two support rails, so that the distance between the abutment surfaces corresponds to a grid dimension of the second scaffolding system.
Features, effects and advantages that are disclosed in connection with the connecting component are also deemed to be disclosed in connection with the scaffolding section. The same applies in reverse, features, effects and advantages which are disclosed in connection with the scaffolding section are also deemed to be disclosed in connection with the connecting component.

In the embodiment shown in
Scaffolding sections 100 can be seen in each of the following drawings. In each of the scaffolding sections 100 in
The first connection region 11 pointing upward is connected to a vertical post 21 of the first scaffolding system 2 via an adapter piece 211. In this case, the adapter piece 211 comprises a projecting region which is introduced into the receptacle 1111 of the first connection region 11. A shoulder of the adapter piece 211 rests on the upper end face of the first connection region 11. The adapter piece 211 additionally has a further, upward-pointing, projecting region, which is inserted into the lower end of the vertical post 21. A shoulder is also arranged on the side facing the vertical post 21 on the adapter piece 211, on which shoulder the end face of the vertical post 21 rests. In the embodiment shown, force is transmitted in the vertical direction by forces being transmitted from the vertical post 21 to the connection region 11 via the two shoulders of the adapter piece 211. Alternatively, it is possible to arrange a projecting region directly on the vertical post 21, which is then inserted into the receptacle 1111. The visible height of the adapter piece 211 also allows the effective overall length of the connecting component 1 to be adjusted, as a result of which the connecting component 1 can be easily adapted to the grid dimension of different first scaffolding systems 2. A vertical post 21 is also connected to the second connection region 13 arranged below. Here, too, an adapter piece 211 is used for the connection. However, the adapter piece used in the second connection region 13 does not have any shoulders like the adapter piece 211 used in the first connection region 11. The adapter piece 211 inserted below is inserted both into the receptacle 131 in the second connection region and into the interior of the vertical post 21. The lower adapter piece 211 aligns the two components just with each other, so that their end faces rest directly on each other. Forces in the vertical direction are thus transmitted below directly between the end faces of the components. A small gap is drawn in the illustration to make the adapter piece visible. When used, this gap cannot be seen. The second scaffolding system 3 is represented here by a horizontal support 31. The second scaffolding system usually includes further scaffolding elements, which are not shown here. The horizontal support 31 comprises two support rails 31a and 31b, which are spaced apart and aligned parallel to one another. The two support rails 31a and 31b here have a C-shaped cross section and are oriented to one another in such a way that the long sides of the C are opposite one another. The two support rails 31a and 31b are positioned relative to one another by at least two spacers 34 (not shown), which are arranged between the two support rails 31a and 31b. The two support rails 31a and 31b have a plurality of recesses at which other elements can be connected to the horizontal support 31. Visible is a forward-facing receiving recess 32 which penetrates both support rails 31a and 31b and has a circular cross-section here. In the embodiment shown in
