Description

Scaffolding node, scaffolding section

The invention relates to a scaffolding node, which is used to connect scaffolding elements extending in different spatial directions. The scaffolding node includes: a connecting sleeve, which is set as a connecting point for at least two scaffolding elements, wherein the connecting sleeve There is a sleeve wall that at least partially surrounds the hollow interior of the connecting sleeve and has a central axis extending in the direction of the longest dimension of the connecting sleeve and in a plan view of the end face of the connecting sleeve Seen is arranged in the middle; and, at least one coupling element for connecting the scaffold node with other scaffold elements, wherein the coupling element is connected with the sleeve wall. The connecting sleeve has at least one slit, which is formed in the sleeve wall, extends parallel to the central axis with the length of the slit, and opens into an end opening arranged on the end surface of the connecting sleeve. The invention also relates to a scaffold section with scaffold nodes and other scaffold elements, and a method for constructing such a scaffold section.

Scaffolding is used for various tasks in the construction field. Facade scaffolding (Fassadengerüste) is used to form the outer surface of the building, for example for painting. Facade scaffolding is usually constructed with a facade scaffolding frame as the main component, and recently it has also been constructed with modular scaffolding. In civil engineering, supporting scaffolding is used to move and hold different building components in place. Such building components are, for example, concrete prefabs, steel beams or steel structures. In addition, for the construction of the building, the required elements (such as temporary structures or formwork) are fixed by means of supporting scaffolding. Bit. Finally, scaffolding can also be used in the field of maintenance or inspection, such as transporting workers in large processing plants, such as oil refineries, to plant parts to be inspected safely. Generally speaking, the basic requirement for scaffolding is that it must be easy to transport and easy to construct. Supporting scaffolding is usually constructed with a supporting scaffolding frame as the main component, and recently there are also modular scaffolding structures. Generally speaking, the supporting scaffold frame consists of two vertical rods (Vertikalstiel), one or two cross rods and one or two vertical struts welded together or fixedly connected to each other in other ways. The facade scaffolding frame is manufactured in a similar way and method. Therefore, the scaffold frame supporting the scaffold and the facade scaffold is constructed in a similar manner.

As a well-known prior art, the following supporting scaffold is known, which is composed of a plurality of supporting scaffold frames and is supported by other scaffold elements. To this end, the supporting scaffold frame is realized two-dimensionally, that is, it extends in a plane. In most cases, the supporting scaffold frame has a rectangular shape. Supporting scaffolding frame is the basic unit of supporting scaffolding. The two-dimensional supporting scaffold frame is connected by the pillar plane to form a three-dimensional scaffold. As the strut plane, so-called strut crosses are often used, which are composed of two intersecting vertical diagonals or are formed by a combination of horizontal crossbars and vertical diagonals. The following supporting scaffolds are also known, in which the plane of the supporting scaffold frame and the plane of the pillars can alternately appear or mix with each other when the supporting scaffold is constructed vertically. The support scaffold using the support scaffold frame is advantageous in that it is easy to construct and the realization of individual components is simple and low in cost. The supporting scaffold formed by the supporting scaffold frame is generally constructed and used as a single supporting scaffolding tower (Traggerüsttürme), wherein these supporting scaffolding towers are connected to each other only by additional materials and a large cost, which can be regarded as a disadvantage.

Another disadvantage of this type of supporting scaffolding tower is that the performance of the plane (carrying capacity and rigidity) is usually different, and the bearing capacity of the pillar plane is usually worse than that of the supporting scaffolding frame.

As a relatively new prior art, so-called modular scaffolding is known, which can be connected and constructed into a three-dimensional scaffold from different modules. This kind of modular scaffolding is not based on a two-dimensional supporting scaffold frame, but on a one-dimensional realization of modular scaffolding components or modular scaffolding components. For this type of modular scaffolding, it is advantageous that compared to the supporting scaffold formed by the supporting scaffold frame and the pillar plane, a higher load-bearing capacity can be achieved with a smaller number of components. Generally speaking, the supporting scaffold formed by modular scaffold elements has a higher bearing capacity relative to the bearing capacity of the heavier pillar plane in the supporting scaffold tower formed by the supporting scaffold frame.

In practice, it often happens that there are already reliable components for supporting scaffolding (especially supporting scaffolding frame and pillar plane) on the construction site, but at the same time, it is necessary to use modular scaffolding with stronger load-bearing capacity at least in part. . However, construction contractors often have concerns about the costly conversion to purely modular scaffolding, and hope to continue to use and integrate their existing supporting scaffolding composed of supporting scaffolding frames.

DE 30 22 439 A1 describes a scaffold in which vertically extending rods are connected by means of double sleeves. The vertically extending rod is inserted into the double sleeve. Additional scaffolding struts can be attached to this type of double sleeve.

KR 10-1625012 B1 discloses a connecting element for two vertically extending rods. The connection between the vertically extending rod and the connecting element is achieved by twisting, which is similar to a bayonet connection (Bajonettverschluss).

Therefore, the task of the present invention is to propose a solution capable of simply and safely connecting the scaffold elements of the known supporting scaffolding or facade scaffolding with the elements of the modular scaffolding.

The task of the present invention is solved by a scaffolding node, which is used to connect scaffolding elements extending in different spatial directions. The scaffolding node includes: a connecting sleeve, which is set as a connection point for at least two scaffolding elements, The connecting sleeve has a sleeve wall that at least partially surrounds the hollow interior of the connecting sleeve and has a central axis that extends in the direction of the longest dimension of the connecting sleeve and is positioned at the end of the connecting sleeve. The end face is arranged in the middle when viewed from the top view; at least one connecting element is used to connect the scaffold node with other scaffold elements, wherein the connecting element is connected with the sleeve wall; wherein the connecting sleeve has at least one gap, which forms In the sleeve wall, the slit length extends parallel to the central axis, and the end opening is arranged on the end surface of the connecting sleeve, and the sleeve wall surrounds the central shaft at a circumferential angle along the slit length direction. The angle is greater than 270°, preferably greater than 300°.

The scaffold node according to the present invention includes a connecting sleeve having a sleeve wall, the sleeve wall at least partially enclosing the inside of the connecting sleeve. Openings or holes are provided in the wall of the sleeve, such as the slits described later. The connecting sleeve has an imaginary central axis, which is used to define other characteristics of the scaffold node. The central axis extends in the longitudinal direction, that is to say in the direction of the longest dimension of the connecting sleeve. When viewed in a plan view of the end face of the connecting sleeve, the central shaft is arranged in the middle of the connecting sleeve. Regarding the middle, it is understood here as the plane center of gravity of the connecting sleeve in the top view. The connecting sleeve is formed, for example, by a cylindrical tube, so the central axis is located at the midpoint of the circular cross section. In addition, the connecting sleeve is formed by a polygonal (especially square) tube, so the central axis passes through the end face of the polygon or the center of gravity of the plane of the cross section. The inside of the connecting sleeve surrounded by the sleeve wall is realized to be substantially centered empty. Of course, protruding elements such as protrusions can be arranged in the interior. The connecting sleeve is provided as a coupling point for at least two scaffold elements. In order to connect the scaffold element with the connecting sleeve, it can be inserted into the inside of the connecting sleeve, for example. Generally speaking, when installed in a scaffold section or scaffold, the central axis of the connecting sleeve is substantially oriented vertically. The connecting sleeve has two end faces, and the two end faces are penetrated by the central axis. The openings arranged on this end face which are surrounded by the sleeve wall and provide access to the inside of the connecting sleeve are called end openings.

The scaffold node according to the present invention also includes at least one coupling element, which is used to connect the scaffold node with other scaffold elements. The other scaffolding elements can be of different types. It is particularly advantageous if the coupling element is realized in such a way that it can be connected to a modular scaffolding element or a modular scaffolding part. The connecting sleeve is specially designed to connect with the scaffold frame supporting the scaffold or the facade scaffold. The scaffold elements are connected to each other by connecting sleeves as coupling points and are therefore preferably formed by the scaffold frame. The connection of the scaffold element to the coupling element of the scaffold node is preferably formed by modular scaffold components. Different elements can be provided as coupling elements, which make it possible to connect with other scaffold elements. For example, the coupling element can be realized as a connecting plate (Verbindungsscheibe), which will be described later. The coupling element is connected with the sleeve wall. In a simple embodiment, the coupling element and the sleeve wall are fixedly and continuously connected to each other, for example by welding. However, it is also conceivable that the coupling element and the coupling sleeve are designed to be detachable from each other, for example by a screw connection.

According to the invention, the connecting sleeve has at least one slit formed in the sleeve wall. Advantageously, the gap is realized as a straight line and extends with a length of the gap parallel to the central axis of the connecting sleeve. The gap forms an opening in the sleeve wall and opens into one of the end openings, which is arranged on the end face of the connecting sleeve. The gap means a groove in the sleeve wall, which interrupts the sleeve wall in the circumferential direction. In this area, where the gap interrupts the sleeve wall in the circumferential direction, the remaining sleeve wall surrounds a circumferential angle with respect to the central axis. The circumferential angle extends from the first boundary wall (Begrenzungswand) of the gap around the central axis to the other second boundary wall of the gap, the second boundary wall being opposite to the first boundary wall. According to the present model, the circle The circumferential angle is greater than 270°, preferably greater than 300°. If the connecting sleeve is viewed from one end side, the two lines extending from the central axis to the first boundary wall or the second boundary wall of the gap also form an angle, which can be referred to as a gap angle. The gap angle and the circumferential angle together form a complete circle of 360°. The gap angle is significantly smaller than the circumferential angle. The circumferential angle is, for example, 300°, so the gap angle is 60° remaining in the complete circle. This means that a large part of the circumference of the connecting sleeve is uninterruptedly surrounded by the sleeve wall in the area of the gap, and only a small part of the circumference is interrupted by the gap. What is achieved by this is that for the scaffold element inserted into the interior of the connecting sleeve, the sleeve wall forms a very large bearing surface or contact surface. Such a large bearing surface is particularly suitable for the absorption and transmission of forces and moments between the scaffold node and the scaffold element connected or connected to it. However, providing this gap can provide additional advantages. Generally speaking, a scaffold frame has frame elements arranged perpendicular to each other. The frame element of the scaffold frame should be pushed into the inside of the connecting sleeve so that another frame element arranged perpendicular to the frame element is introduced into the gap. Thereby, the scaffold element can be pushed far into the inside of the connecting sleeve of the scaffold node. As a result, a safe and stable connection between the scaffold node and the scaffold element can be achieved when connecting. Preferably, the size of the gap in terms of its width, that is, the distance between the first boundary wall of the gap and the second boundary wall of the gap, is dimensioned such that it is slightly larger than the width of the frame element to be introduced. As a result, a clearance fit is formed, which makes it possible to insert the scaffold element into the scaffold node in a simple way. Generally speaking, the frame element has a vertical bar and a frame cross bar oriented perpendicular to the vertical bar. The vertical rod is introduced into the end face of the connecting sleeve, in which the frame cross rod is received and closed by the gap. In some embodiments (where only one slot is provided in the connecting sleeve), the slot correspondingly receives only one frame crossbar. Therefore, the correspondingly dimensioned gap width provides a kind of gap (Freistellung), which makes it possible for the vertical rod to be inserted deeper into the connection sleeve compared to a connection sleeve without a gap provided by the gap. The gap has a more advantageous function: through the corresponding definition of the length of the gap, it is possible to set the distance at which the scaffold frame or the vertical rod and the frame cross rod arranged at right angles can be pushed into the connecting sleeve. Therefore, the length of the gap defines the The stop for the assembly of the hand frame element (Anschlag). When using the scaffold node according to the present invention, such a stop simplifies and speeds up the construction of the scaffold section or scaffold. The scaffold node and the scaffold element only need to be inserted into each other until the frame crossbar stops at the longitudinal end of the gap away from the end opening. This precisely defines the installation position between the scaffold element and the scaffold node. Therefore, when constructing the scaffold section vertically, it is no longer necessary to pin the scaffold node and the scaffold element relative to each other during assembly. The scaffold nodes and the scaffold elements are alternately pinned together, where the positions relative to each other are precisely defined by stops at the ends of the gaps. Therefore, the construction of scaffolding can be greatly accelerated. The coupling elements arranged on the outer wall of the connecting sleeve make it possible to simply connect other scaffold elements, in particular to connect modular scaffold components to scaffold nodes. The coupling element has in particular an interface which matches the connection interface of the modular scaffold part to be connected. There are various modular scaffolding systems on the market. The coupling element is advantageously shaped so that it can be connected to the desired modular scaffolding system. The connecting sleeve represents the interface between the scaffold node and the traditional scaffold frame supporting the scaffold or the facade scaffold. On the other hand, the coupling element is provided as an interface for connection with modular scaffolding components. Therefore, the scaffolding node according to the present invention makes it possible to connect known and existing (especially of scaffolding frames) scaffolding elements with more modern and effective modular scaffolding components in a simple manner. Therefore, through the scaffolding node according to the present invention, the existing scaffolding components in the enterprise's inventory can be simply and safely connected to the newly purchased modular scaffolding components. And therefore, enterprises using the scaffolding node according to the present invention can significantly improve the function of their scaffolding with a small amount of additional purchased parts or scaffolding elements. Advantageously, the coupling element is arranged at the center of the connecting sleeve in a direction parallel to the central axis of the connecting sleeve. Through the symmetrical structure of the scaffold node, a particularly advantageous and statically stable force and moment flow (Momentenfluss) can be obtained through the scaffold node. As a result, the scaffolding section with the scaffolding node according to the invention makes it possible to achieve a safe transfer of forces and moments between mature scaffolding elements and newer modular scaffolding components.

There are many possibilities for the transmission of forces between the scaffold elements inserted in the end face of the connecting sleeve. In a simple embodiment, the interior of the connecting sleeve and the sleeve wall is realized to be smooth and without protrusions. In this case, the two end faces of the introduced scaffold element abut each other inside the connecting sleeve, and force transmission occurs between the end faces or end surfaces of the scaffold element. Optionally, such force in the direction of the central axis of the connecting sleeve can also be guided by the scaffold node or the connecting sleeve. For example, the ends of the scaffold element and the connecting sleeve can be connected to each other via other connecting elements (which transmit force). Thus, for example, openings can be provided in the scaffold element and the connecting sleeve, into which a plug element (Steckelemente) can be inserted as a connecting element. The plug-in element transfers the force from the first scaffold element to the scaffold node, and then transfers the force from the scaffold node to the second scaffold element. It is also possible to provide one or more protrusions or shoulders in the interior of the connecting sleeve. The inserted scaffold element is stopped at this projection or shoulder with its end side, thereby forming a form fit. In this way, it is achieved that the force is transmitted from the first scaffold element to the scaffold node through the shoulder or protrusion and further to the second scaffold element through the shoulder or protrusion.

Another advantage of the scaffolding node according to the present invention is that it can be constructed simply and therefore inexpensively manufactured. In addition, the scaffold node according to the present invention has a compact size, and therefore can be stored and transported in a simple manner. Finally, the scaffold node according to the present invention can match the scaffold elements to be connected in a simple manner. Therefore, for example, the inner diameter of the connecting sleeve can be set by selecting a corresponding prefabricated part as the base (for example, a metal tube) of the connecting sleeve. When introducing the gap, the width and the length of the gap can be designed corresponding to the size of the frame crossbar to be introduced. In addition, the coupling element can also be matched in size and shape to the scaffold element to be connected, especially the modular scaffold component.

In one embodiment, it is proposed that the coupling element surrounds the coupling sleeve. In this embodiment, the coupling element is arranged around the connecting sleeve. Therefore, the coupling element surrounds the connecting sleeve in the circumferential direction. The surrounding can be realized as complete, that is to say as a 360° surrounding the connecting sleeve The central axis. Optionally, the circumference can also be discontinuous, that is, it does not extend around the central axis at 360°. Thus, the coupling element can be realized, for example, in such a way that it surrounds the connecting sleeve by 180° or 270°. In these examples, there are still areas on the circumference of the connecting sleeve where no connecting elements are arranged. Advantageously, the coupling element is fixed on the outer circumference of the connecting sleeve and at least partially abuts on this outer circumference. In another alternative embodiment, a plurality of coupling elements can be distributed to the connecting sleeve in the circumferential direction. Subsequently, each of these coupling elements can be connected to another scaffold element.

In addition, it is proposed that the gap length is at least 0.5 times larger than the inner diameter of the connecting sleeve, in particular at least 1.2 times larger. The length of the gap has an impact on the mechanical stability of the connecting sleeve itself and on the stability of the scaffold section connected by the scaffold node. The gap length is 0.5 times larger than the inner diameter of the connecting sleeve. For this embodiment, this means that the gap length is half the inner diameter of the connecting sleeve. This type of embodiment is particularly mechanically stable, but has the disadvantage that the scaffold element can only be introduced into the connecting sleeve for a short distance. In order to be able to push the scaffold element into the connecting sleeve for a longer distance, the gap length is realized, for example, as large as the inner diameter of the connecting sleeve. In practice, it has proved to be particularly advantageous to have a gap length that is 1.2 times as large as the inner diameter of the connecting sleeve. With regard to the length of the gap, a favorable size is in the range of 30 mm to 70 mm.

It is proposed in an advantageous manner that the overall sleeve length of the connecting sleeve is 2 to 5 times as large as the diameter of the sleeve, in particular 3 times as large, and/or the overall sleeve length is at least 200 mm, preferably at least 300mm. In this embodiment, the overall sleeve length of the connecting sleeve also means that the overall length of the scaffold node is significantly larger than the sleeve diameter of the connecting sleeve. In a preferred embodiment, the overall sleeve length is approximately three times the diameter of the sleeve. Here, the sleeve diameter is understood as the outer diameter of the connecting sleeve. However, the overall sleeve length can also be designed to be 2 to 5 times larger with respect to the inner diameter of the connecting sleeve. The overall sleeve length is advantageously at least 200 mm, but is preferably slightly longer than 200 mm and at least 300 mm. Under normal circumstances, the scaffold element is inserted into the scaffold node from the two end sides of the connecting sleeve. For an overall sleeve length of 200mm, each inserted scaffold element has an insertion length of 100mm, This has (especially in combination with the insert element described later) leads to a mechanically stable connection. For an overall sleeve length of 300mm, each inserted scaffold element already has an insertion length of 150mm, which also improves the mechanical stability of the connection between the scaffold node and the inserted scaffold element. With regard to such insertion lengths of 150 mm or more, a pin connection between the scaffold node and the scaffold element by means of plug-in elements is no longer necessary for a sustainable and elastic connection.

In a preferred design, it is proposed that the length of the gap is greater than the diameter of the sleeve, especially greater than twice the diameter of the sleeve. In this embodiment, the length of the gap is defined relative to the diameter of the sleeve, which represents the outer diameter of the connecting sleeve. Advantageously, the length of the gap is chosen to be greater than the diameter of the sleeve. In order to enable the scaffold element to be inserted into the connecting sleeve for a longer distance, the gap length is preferably realized to be greater than twice the sleeve diameter.

An ingenious way proposes that the gap has two longitudinal borders extending substantially parallel to each other with respect to the sleeve wall, and at its end remote from the end face there is a curved transition between the longitudinal borders. In this embodiment, the gap is defined by two longitudinal boundaries and the transition between these longitudinal boundaries. The two longitudinal boundaries represent the boundary walls of the gap in a direction parallel to the central axis of the connecting sleeve. The transition between the two longitudinal borders is formed by a border wall realized as a curve. Here, the gap is preferably realized in a U-shape, wherein the two longitudinal borders form a U-shaped leg and a curved transition connecting the two legs. Here, the transition portion can have a uniform radius of curvature or may also have a different radius of curvature. In an alternative embodiment, the gap can also be defined by a transition part that is realized by a plane, that is, a non-curved transition part, on its end remote from the end face of the connecting sleeve.

It is proposed in the preferred design that the curved transition portion between the longitudinal boundaries of the gap is provided as a mounting stop for the scaffold element on the scaffold node. In this embodiment, the curved transition portion between the longitudinal boundaries of the gap (which represents the boundary of the gap in the direction of the central axis of the connecting sleeve) is used as the installation stop. When connecting or connecting scaffold components with scaffold nodes, The scaffold element is pushed into the end face of the connecting sleeve until the area of the scaffold element (especially the frame crossbar) stops at the curved transition. It is ensured by this type of mounting stop that the scaffold element and the scaffold node are correctly positioned relative to each other. Here, optionally, the shape of the curved transition portion is realized as a negative form with respect to the stop area of the scaffold element, in particular as a negative form with respect to the frame crossbar. Generally speaking, when constructing a scaffold section or scaffold, no large force is transmitted between the curved transition part and the scaffold element connected to the scaffold node. For the constructed scaffolding section, it is advantageous to realize the force transmission directly in the connecting sleeve between the two inserted scaffolding elements. Alternatively, however, the flow of force can also be guided by the connecting sleeve, for example by a plug element or a shoulder formed inside the connecting sleeve. However, with a corresponding design, it is also possible to transmit forces between the curved area of the gap and the inserted scaffold element that stops at this curved area.

It is also proposed that only this slot is arranged in a region parallel to the central axis in which the slot is arranged, and in particular no other slots are arranged. In this embodiment, only a single slit is arranged in the circumferential direction of the connecting sleeve. In the area along the central axis (that is to say in the longitudinal direction of the connecting sleeve), the sleeve wall is interrupted only by a single gap in each case. Therefore, for example, a slit is arranged from one end surface of the connecting sleeve, and the slit extends parallel to the central axis in the direction of the opposite end surface of the connecting sleeve with the length of the slit. There are no other gaps in this gap length area. This ensures that in the area of the gap, a very large contact surface is provided by the sleeve wall in the circumferential direction. The contact surface is only interrupted by a single gap, so that a very large circumferential angle of at least 270° is achieved in the area of the gap. Such a large circumferential angle or such a large contact surface makes it possible to achieve a safer and more stable force transmission and torque transmission between the connecting sleeve and the scaffold element connected to it. Of course, in the longitudinal direction of the connecting sleeve, that is, along the central axis, multiple (especially two) slits can also be arranged. Advantageously, the slits are arranged starting from each of the two end faces of the connecting sleeve. However, from the two At the beginning of each of the end faces, only one slit is arranged in the circumferential direction of the connecting sleeve in each case in the corresponding area.

In the preferred design, two slits are provided, which respectively lead into two opposite end openings, and the two slits are parallel to the central axis with their respective slit lengths in the direction of the midline of the connecting sleeve.上extended. In this embodiment, two slits are provided, which respectively extend from the end openings on the end face of the connecting sleeve in the direction of the center line of the connecting sleeve. Wherein, the gap lengths of the two gaps can be realized to be the same or different. By providing two gaps (which start from the opposite end openings), the scaffold node can be coupled with each scaffold element on both sides of the connecting sleeve. However, it is of course also conceivable that the connecting sleeve has only one slit starting from the end opening.

A clever way proposes to arrange two slits starting from the respective end openings, wherein the slits are arranged parallel to each other or aligned with each other. In this embodiment, the two slits facing each other are oriented at least parallel to each other. The first slit is arranged from the first end opening and is located at a first circumferential position on the circumference of the connecting sleeve. The second slit extending from the opposite second end opening can be arranged at the same circumferential position, that is, arranged to be aligned with the first slit. In this case, two slits are arranged opposite to each other. However, the second slit may also be arranged at other circumferential positions on the circumference of the connecting sleeve, and the other circumferential positions are different from the circumferential position where the first slit is located. In this case, the two slits are not aligned, but are oriented parallel to each other and parallel to the central axis.

In one embodiment, it is provided that the length of the gap is greater than half of the overall sleeve length of the connecting sleeve. In this embodiment, the gap extends more than half of the overall length of the connecting sleeve. Therefore, this embodiment preferably provides only one slit on the connecting sleeve. The gap realized in this way makes it possible to push the scaffold element into the connecting sleeve over a long distance. Therefore, the result of this design is that the scaffold element is positioned at a different position relative to the scaffold node compared to the embodiment with a shorter slit length. Therefore, by setting the gap length, the relative position between the scaffold nodes and the scaffold elements connected thereby can be changed. By setting the length of the gap, it is longitudinally along the center line of the connecting sleeve. Extending in the direction can realize the scaffold node, which matches the different grids of the scaffold element. As already described before, the scaffold element is pushed into the connecting sleeve and coupled to it, usually a scaffold frame. There are scaffolding frames with different grid sizes. The grid size is defined by the size of the individual elements of the scaffolding frame. For example, the vertical bars and/or the frame cross bars can be realized in different lengths, and thus as scaffold frames with different sizes. In some cases, it is impossible to combine different scaffold frames into a common scaffold section because the sizes or grids of the different scaffold frames do not match each other. In this case, the scaffold node in this embodiment whose gap length extends more than half of the overall length of the connecting sleeve can be used to match or compensate for grid differences in the coupled scaffold elements.

A preferred way proposes that the coupling element is arranged in the middle in the longitudinal direction of the connecting sleeve. In this embodiment, the coupling element is arranged substantially in the middle of the length of the connecting sleeve. Thus, the structure of the scaffold node symmetrical along the central axis is obtained. Such a symmetrical arrangement is particularly advantageous for the safe transfer of force and moment between the connected scaffold element and the scaffold node. However, if necessary, the coupling element can be arranged in another position relative to the connecting sleeve in the longitudinal direction. By arranging the coupling elements off-center in the longitudinal direction of the connecting sleeve, it is possible, for example, to provide a scaffold node that can compensate for the different mesh sizes of the coupled scaffold elements. Optionally, the position of the coupling element is realized to be adjustable along the central axis and therefore in the longitudinal direction of the connecting sleeve, for example by means of a thread provided between the coupling element and the connecting sleeve .

In addition, a preferred way is proposed to realize the connecting element as a connecting plate, wherein the connecting plate has a receiving surface with a plurality of receiving grooves, and the receiving grooves are arranged to interact with other scaffolding elements (especially with modular scaffolding parts). The connecting disk is fixedly connected with the connecting sleeve, and the receiving surface is oriented substantially perpendicular to the central axis of the connecting sleeve. In this embodiment, the coupling element is formed by a connecting disc. The connecting disk is basically realized as a plane and is oriented perpendicular to the central axis of the connecting sleeve. The connecting disc protrudes beyond the outer circumferential surface of the connecting sleeve in the radial direction. Advantageously, the connecting plate is fixedly It is connected to the connecting sleeve (for example depending on the material). Optionally, the connecting disk can also be releasably fixed to the connecting sleeve, for example by means of a fastener. The connecting plate has at least one receiving surface. One or more receiving grooves are arranged in this receiving surface. These receiving grooves can penetrate the entire connecting plate from the receiving surface. These receiving grooves define geometrically shaped interfaces, which are arranged to connect with corresponding interfaces of other scaffold elements. Therefore, the shape and position of the receiving groove match the scaffold element to be connected. Preferably, the modular scaffold component and the scaffold node are connected through a connecting plate. However, it is also possible to connect other scaffolding elements or elements independent of the scaffolding section (for example electrical wires, water pipes or the like) to the connection plate.

In a preferred design solution, it is proposed that the coupling element protrudes beyond the connecting sleeve in the circumferential direction around the gap area by a certain distance, which is smaller than the distance in other areas. In this embodiment, the coupling element, in particular the coupling element realized as a connecting disc, protrudes different distances radially around the outer peripheral surface of the connecting sleeve. At a circumferential position on the outer circumferential surface of the connecting sleeve where one or more slits are arranged, the coupling element protrudes beyond the outer circumferential surface by a certain distance, which is smaller than the protruding distance at other areas or circumferential positions. The reason for this is that the scaffold element formed in the gap radially protrudes from the gap, and thus there is almost no space in the longitudinal direction aligned with the gap to connect the coupling element with other scaffold elements. Therefore, the circumferential position or area of the coupling element adjacent to the slit can be determined to be smaller in the circumferential direction, or completely omitted. In other words, the interface provided by the coupling element for connecting with other scaffold elements is advantageously arranged in the area or circumferential position of the connecting sleeve, where there are no gaps. The coupling element can completely surround the connecting sleeve in the circumferential direction or be arranged only in a partial area of the circumference. However, it is of course also possible to realize the coupling element in such a way that it projects radially beyond the outer circumferential surface of the connecting sleeve by the same distance in the area of the gap.

It is also proposed that the connecting sleeve has at least one locking opening, which passes radially inwardly through the sleeve wall of the connecting sleeve, wherein the locking opening is arranged on the side of the slot facing away from the end opening. In this embodiment, the connecting sleeve has one or more Lock the opening. Connecting elements, in particular plug-in elements, can be introduced into such locking openings, by means of which a positive fit with the scaffold element to be connected can be produced. To this end, the scaffold elements have fixed openings of similar size. In order to formally fix the scaffold node and the scaffold element, the locking opening and the fixing opening are arranged identically to each other, and then the connecting element or the plug-in element is pushed into these openings. Subsequently, the inserted plug-in element avoids undesired separation of the scaffold node and the scaffold element. The locking opening extends through the sleeve wall in the radial direction. In this case, the locking opening can pass through only one sleeve wall or also through two radially opposed sleeve walls. The locking openings can be arranged at different positions in the circumferential direction, that is, around the connecting sleeve. It is also conceivable to form locking openings in the connecting sleeve at different positions in the circumferential direction. In the longitudinal direction of the connecting sleeve, that is, in the direction in which the central axis extends, the locking opening is arranged on the side of the gap, which is away from the end opening and the end surface of the connecting sleeve. In this way, it is possible to insert the connecting element or the plug-in element into the area of the scaffold element, protruding a part of the scaffold element, which is introduced into the gap during coupling. Preferably, the locking opening is arranged between the end of the slit facing away from the end opening and the coupling element. In the embodiment in which there are slits from the two end openings, at least two locking openings are preferably provided, which are respectively positioned between the end of the slit facing away from the end surface and the coupling element. A plurality of locking openings can be provided, each of which is provided for connecting a scaffold node with a differently implemented scaffold element. Through this arrangement of a plurality of different locking elements, the scaffold node can be connected in a simple manner with the scaffold elements (especially the scaffold frame) realized in different ways in a form-fitting manner. Therefore, the scaffold node realized in this way can be particularly flexibly connected with various existing scaffold elements.

In other embodiments, it is proposed that the coupling element is formed by two cup-shaped lock elements, which are constructed in the form of a rim (kragenförmig), wherein the cup-shaped lock element is fixedly connected to the connecting sleeve, and the other cup-shaped lock The element can be axially displaced relative to the connecting sleeve, and there is a gap between the inner diameter of the cup-shaped lock element and the outer diameter of the connecting sleeve, and the end part of the horizontal crossbar can be introduced into the gap. This embodiment represents an alternative to the previous embodiment, in which the coupling element It is formed by connecting disks. In this alternative embodiment, the coupling element of the scaffold node is formed by two cup-shaped lock elements. In addition, through the cup-shaped lock element, other scaffolding elements (for example modular scaffolding parts, which in particular extend horizontally or diagonally in the application) are connected to the scaffolding node. The cup-shaped lock element is in the form of a rim, which means that the cup-shaped lock element has (relative to the opposite end) a smaller diameter at one end thereof. In this case, one of the cup-shaped lock elements is fixedly connected to the connecting sleeve, and the other cup-shaped lock element is axially movably arranged on the connecting sleeve. In order to fix the scaffold element, the axially movable cup-shaped lock element is moved away from the axially fixed cup-shaped lock element. Subsequently, one end piece of a scaffold element (for example a horizontal beam) is introduced between the two cup-shaped lock elements. Horizontal beams are modular scaffolding components. In order to create a form fit between the scaffold node and the horizontal beam, there is a gap between the cup-shaped lock element and the outer surface of the connecting sleeve, into which the end part of the horizontal beam, which is correspondingly formed as a female mold, can be introduced. The horizontal beam is placed in the gap with its end parts, and the axially movable cup-shaped lock element is moved again toward the axially fixed cup-shaped lock element until the end parts of the horizontal beam are form-fittingly surrounded by the two cup-shaped locks Between components. The alternative embodiment of the coupling element is particularly easy to handle. By realizing the coupling element as two cup-shaped lock elements, the scaffold node can be matched with the connection of the modular scaffold component, the interface having a connection with such a cup-shaped lock element.

In another alternative embodiment, it is proposed that the coupling element is formed by a plurality of (especially four) wedge-shaped lock pockets (Keilsperrtasche), wherein the wedge-shaped end area of the horizontal crossbar matches the wedge-shaped lock pocket, and the horizontal crossbar The wedge-shaped end region of the rod can be introduced into the wedge-shaped lock pocket and can be fixed there. In this embodiment, one or more scaffolding elements (especially modular scaffolding parts) are connected to the scaffolding nodes by coupling elements realized as a plurality of wedge-shaped lock pockets. Such a scaffold element can be formed, for example, by a horizontal beam having an end area with a wedge shape. A plurality of wedge-shaped lock pockets are provided as coupling elements, which form a female mold for the end regions of the horizontal beams realized as a wedge. To make the connection, simply introduce the wedge-shaped end area of the horizontal beam Correspondingly formed wedge-shaped lock pockets thereby form a form fit between the horizontal beam and the coupling element. Through this shape matching, the horizontal beam is fixed on the scaffold node. An advantageous way is to provide a plurality of wedge-shaped lock pockets, which are arranged around the circumference of the connecting sleeve at regular distances or angles. By realizing the coupling element as a plurality of wedge-shaped lock pockets, the scaffold node can be matched with the modular scaffold component (provided with correspondingly formed interfaces) in a simple manner.

In another alternative embodiment, it is proposed that the coupling element is formed by a disc (Tellerscheibe), which is fixedly connected to the connecting sleeve, and the disc is provided with a plurality of wedge-shaped grooves substantially penetrating the disc, wherein The wedge-shaped groove is arranged to be connected with a horizontally extending scaffold element (for example, a horizontal beam). The disc is usually realized as a circular ring and represents another embodiment of the coupling element. The disc is fixedly connected with the connecting sleeve and is centered on this. The disc has a plurality of wedge-shaped grooves, which are provided for form-fitting connection with another scaffold element (for example, a horizontal beam). Such horizontal beams have end parts corresponding to such wedge-shaped grooves in cross section, which can be introduced into the disc in a form-fitting manner, thereby enabling the horizontal beam to be fixed to the coupling realized as a disc element. In an advantageous manner, the partition plate has an edge protruding in the longitudinal direction of the connecting sleeve on its outer circumference. This edge makes it possible to achieve an additional form-fitting connection with the horizontal beam and thereby improve the safety of the connection between the scaffold element and the scaffold node. Furthermore, the realization of the coupling element as a disc makes it possible to simply match the scaffold node with the existing scaffold element, which has a correspondingly formed connection interface for connecting with the disc.

The task of the present invention is also solved by a scaffold section, which has at least one scaffold node according to the foregoing embodiment, and further includes: at least one scaffold frame with at least two vertical rods and two frames A cross bar, wherein the ends of the frame cross bar are respectively fixedly connected to one of the vertical bars, so that in the circumferential direction, the vertical bar and the frame cross bar are alternately arranged around the scaffolding frame, wherein the end of the vertical bar protrudes Exceed the frame crossbar and form the connecting end; Among them, one of the connecting ends is inserted into the connecting sleeve of the scaffold node and the frame crossbar connected to the connecting end is arranged in the gap of the connecting sleeve; at least one other scaffold element is connected to the scaffold node, wherein the The other scaffolding elements are formed by other scaffolding frames (which are inserted into the connecting sleeve) and/or by modular scaffolding parts (which are connected with the coupling elements).

The scaffolding section according to the present invention includes at least one scaffolding node according to any one of the preceding embodiments. In an advantageous manner, the scaffolding section comprises a plurality of such scaffolding nodes, wherein the scaffolding nodes can be implemented differently. In addition, the scaffold section according to the present invention includes at least one scaffold frame, which is coupled or connected to at least one scaffold node. For the scaffolding frame, it refers to a frame that is basically realized in two dimensions and represents the components of the supporting scaffolding or facade scaffolding. The scaffold frame includes at least two vertical rods arranged substantially parallel to each other, which extend substantially vertically in the completed construction of the scaffold section. The two vertical bars are connected with two frame cross bars oriented substantially parallel to each other. The frame crossbars are oriented substantially vertically with respect to the vertical rods. The frame cross bars and the vertical bars together form a rectangle arranged in a plane. In the circumferential direction, vertical bars and frame cross bars are alternately arranged around the scaffold frame. The two ends of the vertical rod each protrude beyond the frame cross rod. The end of the frame crossbar is fixed on the outer surface of the vertical rod with its end side, wherein the end of the vertical rod end side protrudes beyond the connection point with the frame crossbar. The protruding end of the vertical rod forms a connecting end, and the connecting end is used to connect or couple with a scaffold node. Each scaffold frame usually has four protruding connecting ends, and thus can be connected to four different scaffold nodes. The scaffolding frame can have other elements, such as frame diagonals, which are arranged between the vertical bars and/or the frame cross bars. For the scaffold section according to the present invention, at least one connecting end of the scaffold frame is inserted into at least one scaffold node and connected to it. In this case, the connecting end is inserted into the end opening of the connecting sleeve of the scaffold node. The frame cross-bars arranged adjacent to the connecting ends inserted into the scaffold nodes are arranged in the gaps of the connecting sleeves. The frame cross bar is surrounded by a gap at its connection point with the vertical bar. therefore, The gap represents the gap (Aussparung) in the scaffold node through which the frame crossbar is guided. By setting gaps on the scaffold nodes, the scaffold frame can be further (compared to no such gaps) introduced into the scaffold nodes. This feature of the scaffold frame can further introduce the characteristics of the scaffold node, which can ensure a mechanically stable connection between the two elements. As previously described in some embodiments of the scaffold node, the gap of the scaffold node can be used as an installation stop when the scaffold node is connected to the scaffold frame. The connecting end of the scaffold frame is simply pushed into the scaffold node until the frame crossbar stops at the end of the gap facing away from the end opening of the connecting sleeve. In this way, the insertion depth of the scaffold frame in the scaffold node can be simply and safely defined, so that the scaffold section can be constructed quickly and without error. In this case, the gap can surround the frame cross-bar with a small distance, especially the lower end of the frame cross-bar, which is connected with the vertical rod close to the connecting end. In this case, there is a clearance fit between the frame crossbar and the gap, and this clearance fit ensures simple assembly and disassembly. When the connection between the scaffold node and the connecting end is completed, a large part of the outer peripheral surface of the connecting end of the scaffold frame abuts against the inner peripheral surface of the connecting sleeve. This abutment between the two peripheral surfaces is achieved in the area defined by the angle of the circumference previously described in terms of the scaffold node. Through this large circumferential angle, which is provided by the scaffold node according to the invention, a very large contact surface between the scaffold node and the scaffold frame is ensured in the scaffold section according to the invention. With this large contact surface, force and moment can be safely and reliably transmitted between the two elements.

The scaffold section according to the present invention includes at least one other scaffold element, which is connected to the scaffold node. This other scaffolding element can be formed as a modular scaffolding part connected with the coupling element of the scaffolding node. The connecting element has one or more interfaces, which are compatible with the connecting interfaces of the modular scaffolding components. The connection interface of the modular scaffolding component is different from the connection end of the scaffold frame in terms of shape and size. Therefore, the connection between the scaffold frame and the scaffold node is realized only by inserting the connecting sleeve, while the connection of the modular scaffolding components is only realized by This is achieved by coupling with the coupling element. Therefore, the scaffold node represents the connection between the scaffold frame and the modular scaffold component (Bindeglied). Through this function as a connection, the scaffold node can realize the scaffold section realized in different ways in a simple manner. Therefore, scaffold frames and modular scaffold components designed in different ways can be flexibly connected to each other and used together in a simple manner. Alternatively or additionally, the scaffold section according to the present invention can be connected to other scaffold frames, wherein the connecting end of the other scaffold frame is inserted into the second end of the connecting sleeve, and the second end It is opposite to the inserted first connecting end of the first scaffold frame. Therefore, the scaffolding section according to the present invention includes a scaffolding node, at least one first scaffolding frame and additional at least one modular scaffolding component, or a second scaffolding frame. Of course, the scaffold section according to the present invention can also include more such elements or components. The scaffolding section according to the present invention can be further expanded so that it represents a complete scaffolding. In this case, the scaffolding section includes multiple scaffolding nodes, scaffolding frames, and modular scaffolding components.

In the preferred design, it is proposed that the scaffold node is connected to two scaffold frames, wherein the respective connecting end of each scaffold frame is introduced into the opposite end of the connecting sleeve, and is connected to the corresponding connecting end The frame cross-bars are respectively arranged in the gaps, which open into the end openings of the connecting sleeve. In this embodiment of the scaffold section, the scaffold node is connected or coupled with two scaffold frames. The connecting end of each of the two scaffolding frames is respectively inserted into the end surface of the connecting sleeve of the scaffolding node. In this case, the frame crossbars adjacent to the connecting ends of the scaffold frame and connected to the corresponding vertical rods are respectively introduced into the gaps provided in the scaffold nodes, and are surrounded by the gaps in the inserted state. The end sides of the connecting ends can be in contact with each other inside the connecting sleeve in the coupled state, so that force can be directly transmitted between the two connecting ends. Optionally, the connecting end can also be connected to or stay on an element of the scaffold node (for example, a protrusion in the interior of the connecting sleeve). In this case, first realize the transmission of force from the connection end to the scaffold node, and then realize the transmission of the force from the scaffold node to the second connection end. It is also conceivable that the force also Transfer between the frame crossbar and the gap, as long as the frame crossbar is connected to the corresponding gap. Instead of the second connecting end or the second scaffold frame, other scaffold elements can be connected to the scaffold node by inserting into the connecting sleeve, and then become part of the scaffold section. Such other scaffolding elements can be formed by railing posts, for example.

In addition, it is proposed that the scaffold frame has at least one frame connecting element, which is fixedly connected to the vertical rod and/or the frame cross rod, wherein the frame connecting element is arranged to be connected to a strut rod (Strebenstab), which is used for A number of scaffold frames are connected to each other, in particular in which the frame connection elements are realized as inclined fingers (Kippfinger) or railing hooks (Geländerhaken). In this embodiment, the scaffold frame has at least one frame connection element. In the case of a frame scaffold, it can be, for example, a support scaffold or a facade scaffold. As mentioned above, the scaffold frames are connected to each other by the pillar planes, thereby forming a three-dimensional scaffold. The plane of the pillar must be connected to the scaffold frame. For this type of connection between the scaffold frame and the pillar plane, frame connection elements are provided. When constructing a frame scaffold or a scaffold section, the frame connecting element is connected, for example, to a pillar cross or a pillar rod. The pillar cross can be formed of a plurality of pillar rods. The frame connection elements are usually arranged in the same plane as the vertical bars and frame cross bars of the scaffold frame. In this case, the frame connection elements can be arranged towards the inside of the scaffold frame. For example, the frame connection element can be realized as an inclined finger. The inclined finger is a cylindrical element, and the strut rod can be inserted into the inclined finger. In order to ensure that the inserted support rod will not accidentally fall off the inclined finger, a finger-shaped, movable element is provided on the inclined finger, which will be inclined and thus fixed after the support rod is inserted. . After such an inclination, the strut rod can no longer be detached from the inclined finger. Alternatively, the frame connection element can also be formed by a railing hook. The railing hook is an element that is configured to connect with the scaffolding railing. When someone is walking on the plane of the scaffold or scaffold section and these people are at risk of falling, a scaffold railing is required.

It is proposed in an advantageous manner that the two end faces of the two connecting ends introduced into the connecting sleeve are connected to each other, or the two connecting ends introduced into the connecting sleeve are connected to each other by means of at least one plug-in element. Are connected to each other in a form-fitting manner, in which the plug element is introduced into at least one locking opening in the connecting sleeve and at least one fixing opening in the connecting end, so that the force acting parallel to the central axis can be applied to the two Transfer between connecting ends. The force transmission from the connecting end inserted in one side of the connecting sleeve to the connecting end inserted on the opposite side of the connecting sleeve can be realized in different ways. In a simple embodiment, the two end faces of the two connecting ends meet inside the connecting sleeve, thereby enabling direct force transmission at this position. Alternatively or additionally, one or both of the connecting ends can be pin-connected to the connecting sleeve of the scaffold node. The pinning is achieved by means of a plug-in element, which is inserted through at least a part of the connecting sleeve and at least a part of the connecting end. This produces a form-fitting connection between the connecting end and the scaffold node. In this case, force can be transferred from the first connecting end to the scaffold node in a form-fitting manner. Of course, the reverse is the same. The second connecting end inserted into the connecting sleeve is pin-connected in the same way, that is, connected in a form-fitting manner, and the force can be correspondingly formed between the connecting sleeve and the second connecting end provided in a form-fitting manner. Pass between. In order to produce a form-fitting connection with the plug-in element, the connecting sleeve of the scaffold node has at least one locking opening, and the connecting end has at least one fixing opening. The locking opening and the fixing opening have an inner section (Innenquerschnitt), which is slightly larger than the outer section (Außenquerschnitt) of the plug-in element. As a result, the plug-in element can be introduced into the two openings in a clearance fit manner. A fixing element can be provided on the plug-in element, which can be manipulated after the pinning, so as to prevent the plug-in element from accidentally falling out or being pulled out of the opening. It is also possible to achieve by appropriately selecting the tolerances that when constructing the scaffold section, the end faces of the two connecting ends inserted into the connecting sleeve are connected to each other. Nevertheless, the plug-in element is used to connect the scaffold node and Connect the ends. In this case, the pressure is directly transmitted between the two connecting ends through the end faces that abut each other. If tension occurs, there will be a small amount of tension between the two end faces of the connecting end in the connecting sleeve. spacing. If further tension is applied, the plug-in element and the connecting element and the scaffold node are engaged in a form-fitting manner. In this way, it can be avoided that the scaffold element is pulled out of the scaffold node. Such unintentional pull-out can occur, for example, when constructing or disassembling the scaffold section, and can be reliably avoided by additionally providing plug-in elements. In order to avoid overdetermination in this case, the clearance fit between the plug-in element and the locking opening and the fixing opening can be increased. In this case, the connecting end can start from the state where the opposite connecting end abuts inside the connecting sleeve, and pull out a short distance from the connecting sleeve, until the plug element and the locking opening and/or The fixed openings are joined in a form-fitting manner. The corresponding tolerances in the dimensions of the openings and the plug-in elements are also advantageous in compensating for the dimensional tolerances in the length of the connecting ends of the scaffold frame.

In a preferred design, it is proposed that the outer peripheral surface of the connecting end at least partially abuts against the inwardly facing surface of the sleeve wall, especially in the area defined by the circumferential angle of the sleeve wall Abutment, wherein through the abutment of this surface, the force acting perpendicular to the central axis and the moment acting around the axis at an angle (especially at a right angle) to the central axis can be transmitted between the connecting end and the scaffold node. When connecting the scaffold node and the scaffold frame, the outer peripheral surface of the connecting end abuts the inner peripheral surface or surface of the connecting sleeve. The inwardly facing surface of the connecting sleeve is only interrupted by the gap. The inwardly facing surface extends in the area defined by the circumferential angle. Since the circumferential angle is selected to be larger, the bearing surface or contact surface between the scaffold node and the connection end of the scaffold frame is also large. Through this mutually abutting surface, the force and moment are transmitted between the scaffold node and the scaffold frame. On the one hand, the force is transmitted through these surfaces, which are oriented perpendicular to the central axis of the connecting sleeve. In addition, a torque is transmitted, which occurs around an axis, which is arranged at an angle relative to the central axis. The force acting parallel to the central axis of the connecting sleeve is transmitted through the aforementioned mechanism, that is, not only directly from the scaffold frame connected with the scaffold node to another scaffold frame, or through the connection end of the scaffold frame and the scaffold node The shape fit is produced by the pin connection with the plug-in element. Therefore, the scaffold section with the scaffold node can transmit tension and pressure between the scaffold elements connected or coupled with the scaffold node. And torque. It is also possible that a certain amount of torsional force is transmitted through the scaffold node, which torsional force is generated between different scaffold elements in the scaffold section. The gap in the connecting sleeve greatly contributes to significantly increasing the contact surface between the connecting end of the scaffold frame and the connecting sleeve, as compared with the connection of scaffold nodes that do not have a gap. Since the frame crossbar can be pushed into the gap, the connecting end and thus the vertical rod of the scaffold frame can be pushed significantly further into the connecting sleeve, thereby significantly increasing the bearing surface. With the enlarged bearing surface, greater forces and moments can be transmitted through the connection.

It is also proposed that the coupling element is connected to at least one modular scaffolding component, wherein the modular scaffolding component is formed by a horizontal crossbar or a horizontal diagonal piece or a vertical diagonal piece. In this embodiment, at least one modular scaffold part is connected to the coupling element. In addition, other (that is, multiple) modular scaffold components can be connected to the coupling elements of the scaffold node. Modular scaffold components can generally be all scaffold elements belonging to a modular scaffold. Here, modular scaffolding is understood as the following scaffolding, which can be combined and assembled into different overall shapes and overall sizes from different components according to the modular principle (Baukastenprinzip). Thus, for example, the horizontal cross-bars of the modular scaffolding (which are part of the modular scaffolding) are connected with the coupling element. Other possible modular scaffolding components are horizontal diagonal pieces or vertical diagonal pieces. Of course, other various types of modular scaffolding components can also be connected with the coupling element. In addition, the coupling element is also connected to other elements, for example by means of ropes, which are used to lanyard or fix the scaffold.

Finally, the task of the present invention is solved by a method for constructing a scaffold section according to any one of the foregoing embodiments, the method includes the following steps: (A) Push the scaffold node to the first connection of the scaffold frame At the end, the sleeve wall pushes on the outer peripheral surface of the connecting end, and the frame cross bar of the scaffold frame connected to the connecting end is introduced into the gap of the connecting sleeve until the end of the gap is away from the end opening Stop at the frame crossbar, (B) connect the other scaffolding frame to the scaffolding node by pushing the connecting end of the other scaffolding frame into the connecting sleeve opposite to the first connecting end End, and/or, will at least one A modular scaffold component is connected with the connecting element of the scaffold node. The method according to the invention is executed in order to construct the scaffolding section according to the invention. The method is preferably performed in a given order of steps (A) and (B). When the method steps are reversed, a similar method can be used to disassemble or disassemble the scaffold section according to the present invention. In the first method step (A), the scaffold node is connected or coupled with the scaffold frame. To this end, the connecting sleeve of the scaffold node is pushed onto the connecting end of the scaffold frame. Of course, this movement mode can also be reversed, and the connecting end of the scaffold frame is pushed into the connecting sleeve of the scaffold node. During the relative movement of the scaffold frame with respect to the scaffold node, the frame crossbar fixed adjacent to the connection end is introduced into the gap of the connection sleeve, and is further pushed in the gap. Continue to introduce the connecting end into the scaffold node until the frame crossbar stops at the end of the gap away from the end opening. And this kind of stop restricts the relative movement between the scaffold frame and the scaffold node. Through this stop, the correct positioning between the scaffold node and the scaffold frame is ensured. After setting the relative position between the scaffold node and the scaffold frame, in method step (B), other scaffold elements are connected to the scaffold node. The other scaffolding elements relate to other scaffolding frames, which are introduced into the connecting sleeve with the connecting end, similar to method step (A). Optionally, other scaffolding elements can be formed by modular scaffolding components, which are connected to the coupling elements of the scaffolding nodes. Of course, multiple other scaffolding elements (such as a scaffolding frame and a modular scaffolding component) can also be connected to the scaffolding node. Once all the required scaffolding elements are connected to the scaffolding nodes, you can compare the steps (A) and (B) to add other scaffolding nodes and scaffolding elements to the scaffolding section until the constructed scaffolding section meets the requirements The request. The method according to the present invention can be executed in a simple way and with a small time cost. Among them, the correct relative position between the scaffold node and the scaffold frame connected to it is set by the stop of the corresponding frame crossbar at the end of the gap away from the end opening. The setting of this connection and relative position is It is very easy and does not require any special expertise. For method step (A), no tools are required, and no measurement or similar test steps are required to control the method steps. this In addition, according to method step (B), other scaffold elements are connected to the scaffold node, which can be performed very simply and with a small time cost. Therefore, the method according to the invention makes it possible to construct the scaffolding section quickly and therefore cost-effectively. At the same time, especially through the design of the scaffold nodes, it is ensured that the scaffold elements are correctly and firmly connected to each other. Therefore, by this method, a stable and reliable scaffold section can be constructed in a short time.

The advantages and effects described in combination with the scaffold node and the scaffold section can be transferred to the method according to the present invention. Vice versa, the effects and advantages of this method can be transferred to scaffold nodes and scaffold sections.

In the drawings, the same elements are provided with the same reference signs. In general, the characteristics of the elements described for one figure are also applicable to other figures. The upward or downward direction indicates reference to this drawing, and its meaning can be transferred to other drawings.

Fig. 1 shows a perspective view of a scaffold node 1 according to an embodiment of the present invention. The scaffold node 1 is used to connect scaffold elements extending in different spatial directions. The connection and arrangement of the scaffold node 1 in the scaffold section 100 are shown in FIG. 2. The scaffold node 1 includes a connecting sleeve 2, which is shown in the vertical direction in FIG. 1. In the illustrated embodiment, the connecting sleeve 2 is formed by a cylindrical tube composed of iron-based material. The connecting sleeve 2 is realized as being hollow inside, wherein the sleeve wall 21 at least partially surrounds the hollow inside of the connecting sleeve. The connecting sleeve 2 may also have other shapes. For example, the connecting sleeve 2 can also be formed by a tube having a quadrilateral (for example, square) cross-section. The connecting sleeve can also be made of other materials, such as plastic. The dotted line shown in FIG. 1 is the central axis MA of the connecting sleeve 2. The central axis MA extends in the longitudinal direction of the connecting sleeve 2 and is arranged in the middle of the cross-sectional view of the connecting sleeve 2 in a plan view of the end face 27 of the connecting sleeve 2. In the illustrated embodiment, the central axis MA also represents the axis of symmetry of the connecting sleeve 2 at the same time. The central axis MA is an imaginary auxiliary geometric figure, which is defined in order to describe other characteristics and shapes of the scaffold node 1. The connecting sleeve 2 has an overall sleeve length 24 which extends from the end face 27 toward the opposite end face 27 of the connecting sleeve. The connecting sleeve 2 has a sleeve diameter 25 on its outer peripheral surface. The inner diameter of the connecting sleeve 2 is obtained by subtracting twice the wall thickness of the sleeve wall 21 from the sleeve diameter 25.

The scaffold node 1 also includes a coupling element 3, which is used to connect the scaffold node 1 and other scaffold elements. The coupling element 3 is here fixedly mounted at the outer peripheral surface of the connecting sleeve 2. In the embodiment shown, the coupling element 3 is formed by a connecting disk 31 in FIG. 1. The connecting plate has two receiving surfaces 311 arranged opposite to each other. Only one receiving surface 311 facing upward can be seen in FIG. 1. Facing downwards is another receiving surface 311, which has the same shape as the receiving surface 311 facing upwards. In the connecting plate 31, a plurality of receiving grooves 312 are formed starting from the receiving surface 311. The receiving groove 312 represents an interface for connecting with other scaffold elements (especially with the modular scaffold part 6). The receiving groove 312 can, for example, have a shape that is realized to be complementary to the corresponding connection interface 61 on the other scaffold elements shown, in particular on the modular scaffold part 6. The shape, size and position of the receiving groove 312 in the connecting plate 31 are not limited to the embodiment shown in FIG. 1, but can be changed according to the needs of the scaffold elements to be connected. In the embodiment shown, the coupling element 3, which is realized as a coupling disc 31, is made of a flat disc with an otherwise substantially square cross-section. The front right corner of the original square cross-section is removed. Therefore, the coupling element 3 realized as the coupling disc 31 protrudes beyond the outer peripheral surface of the coupling sleeve 2 at different distances in the circumferential direction of the coupling sleeve 2. In the area facing the front right, where two slits 22 are also arranged in the connecting sleeve 2, the distance of the coupling element 3 protruding beyond the connecting sleeve 2 is smaller than in other areas. The reason is that when connecting the scaffold node 1 with one or two scaffold frames 4, one or two frame cross bars 42 are guided through the gap 22 and then extend from the gap 22 in the radial direction of the central axis MA come out. The frame crossbar 42 guided through the gap 22 will prevent other scaffolding elements (especially the modular scaffolding part 6) from being connected to the front right area of the coupling element 3, which is required for this type of connection by blocking Space. Therefore, as viewed from the circumferential direction of the connecting sleeve 2, in the area of the gap 22, the coupling element 3 is realized with a small protruding distance. As a result, the accessibility and graspability of the frame cross bar 42 introduced into the gap 22 are improved at the same time, so that Therefore, the installation and disassembly of the scaffold node 1 and the scaffold frame 4 are simplified. Of course, the coupling element 3 can also protrude evenly beyond the outer surface of the connecting sleeve 2 in the circumferential direction. It is also possible that the coupling element 3 is not present in the area of the gap 22 at all. In this case, the coupling element 3 does not completely surround the connecting sleeve 2 but only in a partial area of the circumference. In the embodiment shown, the coupling element 3 completely surrounds the connecting sleeve 2 on the circumference. As a result, the coupling element 3 can be connected to the connecting sleeve 2 around the circumference, so that a very stable connection between the two elements can be achieved. At the same time, in the illustrated embodiment, the corner removed from the front right of the connecting element 3 of the scaffold node 1 makes the operation very ergonomic when connecting with the scaffold frame 4. In the illustrated embodiment, the coupling element 3, which is implemented as the connecting disc 31, is made of iron-based material and is connected to the connecting sleeve 2 by a welding connection.

The connecting sleeve 2 has at least one slit 22 formed in the sleeve wall 21 and extending parallel to the central axis MA with a slit length SL. In the embodiment shown in FIG. 1, the connecting sleeve 2 has two slits 22 arranged in alignment with each other, which slits extend from the end face 27 in the direction of the coupling element 3. The two slits 22 respectively lead into the end opening 23, which represents the opening on the end surface 27 to the inside of the connecting sleeve 2. The upwardly facing first slit 22 starts from the lower end opening 23 and extends upward with a slit length SL1. The downwardly facing second slit 22 starts from the upper end opening 23 and extends downward with a slit length SL2. In the embodiment shown, the two slit lengths SL1 and SL2 are the same length. However, the two slit lengths SL1 and SL2 can also be of different lengths. Each of the slits 22 is restricted by two boundary walls in the circumferential direction of the connecting sleeve 2. In the embodiment shown, the two boundary walls represent two longitudinal boundaries that are substantially parallel to each other. Here, the longitudinal boundary is straight. Between the longitudinal boundaries, curved transition portions are provided as other boundary walls of the gap 22. In the embodiment shown, the curved transition portion is semicircular. For example, when a finger milling cutter is used for milling to form the gap 22 in the connecting sleeve 2, such a shape can be formed. In the embodiment shown, the two slits 22 are aligned with each other. This means that the two slits 22 are arranged to the same position in the circumferential direction of the connecting sleeve 2. However, it is optionally also possible that the two slits 22 are only parallel to each other, but not arranged at the same position in the circumferential direction of the connecting sleeve 2. In this case, the slit 22 faces different directions in the circumferential direction of the connecting sleeve 2.

For the safe and reliable function of the scaffold node 1, it is the optimal width of the gap 22 that plays a decisive role. The width of the gap 22 should be just enough to enable the frame cross bar 42 of the scaffold frame 4 to be introduced into the gap 22 in a clearance fit manner. However, in this case, the gap 22 should be realized as narrow as possible so as not to weaken the sleeve wall 21 in the area of the gap 22 as much as possible. The width of the gap 22 is defined by defining the circumferential angle UW of the remaining sleeve walls 21 in the area of the gap 22. In FIG. 1, two auxiliary lines are drawn starting from the central axis MA shown by the dashed line, and the two auxiliary lines extend toward the longitudinal boundary of the slit 22 or the boundary wall arranged in the longitudinal direction. These longitudinal boundaries simultaneously represent the boundaries of the sleeve wall 21 in the area of the gap 22. The circumferential angle UW is defined between two auxiliary lines, that is, between the longitudinal boundaries of the sleeve wall 21 in the area of the gap 22. As can already be seen from FIG. 1, in the illustrated embodiment, the circumferential angle UW is significantly larger than the three-quarter circle, that is to say larger than 270°. This means that the sleeve wall 21 surrounds most of the circumference of the connecting sleeve 2 in the area of the gap 22 and is only interrupted by the gap 22 in a small partial area. According to the present invention, the circumferential angle UW is greater than 270°, preferably greater than 300°. In general, it is true that the larger the circumferential angle UW is selected, the more stable the connecting sleeve 2 is in the area of the gap 22. In order to make the connecting sleeve 2 as stable as possible in the area of the gap 22, and thus it is possible to transmit as much force and moment as possible, in the longitudinal area of the connecting sleeve 2 (where the gap 22 is arranged), the second is not arranged Two gap 22. The second gap 22 arranged in this area will additionally weaken the connecting sleeve 2 in this area and reduce the circumferential angle UW of the remaining sleeve wall 21. Therefore, it is necessary to avoid arranging the second slit 22 in the same longitudinal region of the slit 22. In the embodiment shown In this, the circumferential angle UW around the two slits 22 is realized to be the same. However, it is also possible that the circumferential angle UW of the slit 22 around the upper part and the slit 22 around the lower part are realized to be different.

In the embodiment shown in FIG. 1, a plurality of locking openings 26 are formed in the connecting sleeve 2. Here, the locking opening 26 is realized as a circular opening extending through the sleeve wall 21 in the radial direction toward the connecting sleeve 2. To this end, the locking opening 26 is configured to create a form-fitting connection between the scaffold node 1 and the scaffold frame 4 connected to it. In order to produce such a form-fitting connection, a plug-in element is formed in at least one locking opening 26, which is not shown in FIG. 1. At the same time, a plug-in element is introduced into at least one corresponding fixing opening 412 of the scaffold frame 4. These relationships are shown in cross-sectional view in FIG. 5. In the embodiment shown in FIG. 1, the locking openings 26 are each located between the coupling element 3 and the end of the slot 22 facing away from the corresponding end opening 23. In the circumferential direction of the connecting sleeve 2, as shown in FIG. 1, a plurality of locking openings 26 can be arranged. In this way, it is possible to produce a shape fit with different scaffold frames 4, in which the corresponding fixing openings 412 are arranged in different ways in the circumferential direction. Thus, the arrangement of a plurality of locking openings 26 on the circumference of the connecting sleeve 2 increases the flexibility in the usability of the scaffold node 1 and the scaffold frame 4 implemented in different ways.

Fig. 2 shows a perspective view of a scaffold section 100 according to an embodiment of the present invention. Fig. 2 shows a scaffolding tower with a plurality of scaffolding sections 100 according to embodiments of the present invention. The scaffolding tower is mainly constructed by the scaffolding frame 4, which are connected to each other by the plane of the pillars. On the right-front side of the scaffold tower, four scaffold frames 4 are arranged one on top of the other, and they are connected to each other by scaffold nodes 1 respectively. Each of the scaffold frames 4 includes two vertical bars 41 that are oriented parallel to each other and two horizontal bars 42 that are oriented parallel to each other. The two vertical bars 41 and the two frame cross bars 42 of the scaffold frame 4 are arranged in a common plane. Each of the scaffolding frames 4 is arranged with a frame diagonal piece 44, where the frame diagonal piece 44 is fixed to each of its two ends The corresponding frame crossbar 42. The scaffolding frame 4 is a basic component of frame scaffolding (for example, supporting scaffolding or facade scaffolding) realized in two dimensions. On the side of the scaffold tower facing the left and rear, three scaffold frames 4 are also arranged one on top of the other and connected to each other by a scaffold node 1. Perpendicular to the plane constructed by the scaffold frame 4 toward the right front and toward the left rear, respectively, there are arranged pillar planes toward the left front and the right rear. The pillar plane connects the planes realized in two dimensions by the scaffold frame 4 into a three-dimensional scaffold tower. The pillar planes each include three pillar crosses 5. Each of these strut crosses 5 is constructed by two strut rods 51 connected to each other. The support rods 51 are each connected to the scaffold frame 4 through frame connection elements 43 at their ends. The frame connecting elements 43 are each arranged on the scaffold frame 4. The details of these connections can be seen in Figure 3. The part of the scaffolding tower in Figure 2 described so far is formed by the components of the frame scaffolding. However, these components of the frame scaffolding have been partially interconnected with the scaffolding node 1 according to the present invention. The scaffold nodes 1 each have coupling elements 3 beside the connecting sleeves 2 (which are used here to connect the scaffold frames 4 arranged one above the other). With the aid of the coupling element 3, other scaffolding elements can be connected. In FIG. 2, for example, two modular scaffold components 6 are respectively installed on two scaffold nodes 1, which are respectively connected with the coupling elements 3. Starting from these exemplarily shown modular scaffolding components 6, it is possible to connect other scaffolding elements (especially modular scaffolding components 6) to the scaffolding tower. As can be seen in Figure 2, the scaffold node 1 is used to simply connect the frame scaffold and the modular scaffold. The scaffold section 100 according to the present invention includes at least one scaffold node 1 and a scaffold frame 4, and additional other scaffold frames 4 or modular scaffold components 6.

FIG. 3 shows another perspective view of the scaffold section 100 according to an embodiment of the present invention. In FIG. 3, the cross section of the scaffold in FIG. 2 is enlarged and shown. A scaffold node 1 is arranged in the center, where it is connected with two scaffold frames 4 arranged one above the other. Two scaffolding frames 4 are connected by them The end 411 is pushed into the inside of the connecting sleeve 2. The connecting end 411 in the non-inserted state can be seen in FIG. 3. The two scaffold frames 4 are pushed into the connecting sleeve 2 so that each frame cross bar 42 is located in the gap 22 of the scaffold node 1. In this case, the remaining sleeve wall 21 around the gap 22 abuts against the connecting end 411 of the scaffold frame 4 in a large area. As a result, the stable and safe transmission of force and moment between the scaffold frame 4 and the scaffold node 1 can be realized. At the scaffold frame 4 installed with the scaffold node 1 from below, the frame diagonal piece 44 can be seen, which is fixedly connected to the frame crossbar 42 here. The two scaffold frames 4 connected with the scaffold node 1 are respectively connected with the pillar rods 51 of the pillar cross member 5. Only the corresponding ends of these struts 51 can be seen in FIG. 3. The support rods 51 are respectively fixed to the frame connecting elements 43 arranged on the vertical rods 41. The frame connection element 43 is here fixedly arranged to the vertical rod 41. The connection between the frame connection element 43 and the support rod 51 is realized to be detachable, so that the support rod 51 can be installed with the scaffold frame 4 when the scaffold section 100 is constructed, and when the scaffold section 100 is disassembled It can be detached from the scaffolding frame 4. The frame connection element 43 is realized here as an inclined finger. Of course, the frame connecting element 43 can also be arranged on the frame cross bar 42. It is also possible that the frame connecting element 43 has a shape different from that shown in FIG. 3. The scaffold node 1 includes a coupling element 3 arranged here in the middle of a connecting sleeve 2. The coupling element 3 is realized as a connecting disk 31 in the embodiment shown. Two modular scaffolding parts 6 (which point to the front right and the rear right, respectively) are connected with the coupling element 3. The two modular scaffolding parts 6 are here frame crossbars of the modular scaffolding. Alternatively or additionally, it is also possible to connect other modular scaffolding parts 6 with the coupling element 3. The modular scaffolding parts 6 respectively have connection interfaces 61 at their ends. The connection interface 61 is designed such that it can be detachably connected with the receiving groove 312 of the connection plate 31. In Fig. 3, the modular scaffold part 6 is fixed to the coupling element 3 so that it extends from the coupling sleeve 2 in the radial direction. Of course It is also possible that the modular scaffolding part 6 is fixed on the coupling element 3 so that it extends in other spatial directions.

Fig. 4 shows a perspective view of a part of a scaffold section 100 according to an embodiment of the present invention. In Fig. 4, a part of the scaffold section 100 in the construction state can be seen. A scaffold node 1 is arranged in the center. Here, the scaffold node 1 has been connected to the scaffold frame 4 on its underside. The connecting end 411 of the scaffold frame 4 arranged in the lower part has been inserted into the downwardly facing end opening 23 of the connecting sleeve 2. The frame crossbar 42 of the scaffold frame 4 arranged at the lower part is introduced into the slot 22 oriented downward. In the state shown, the upwardly facing surface of the frame crossbar 42 is stopped at the end of the lower slot 22 facing the coupling element 3. Through this stop, the correct positioning between the scaffold node 1 and the scaffold frame 4 arranged in the lower part is ensured in a simple manner. It can be seen that there is another scaffold frame 4 above the scaffold node 1, which has not yet been connected to the scaffold node 1. The scaffold frame 4 arranged on the upper part has a fixing opening 412, which is realized here as a circular opening. The fixing opening 412 is provided for establishing an additional form-fitting connection with the scaffold node 1. Here, the fixing opening 412 is arranged in the vertical rod 41 between the downwardly facing end of the connecting end 411 and the frame cross rod 42. Starting from the state shown in FIG. 4, the scaffold frame 4 moves downwards in order to establish a connection with the scaffold node 1. In this case, the protruding connecting end 411 (which is a part of the vertical rod 41) is introduced into the upwardly facing end opening 23 of the connecting sleeve. In the further process of this introduction, the area of the frame cross bar 42 arranged near the connection point between the vertical bar 41 and the frame cross bar 42 is introduced into the upwardly facing gap 22 and moves further therein. This pushing in of the upper scaffold frame 4 continues until the downward facing surface of the frame crossbar 42 is stopped at the end of the upper gap 22 oriented toward the coupling element 3, or the two connecting ends of the scaffold frame 4 The two end surfaces of the portion 411 abut against the inside of the connecting sleeve 2. In this state, the upper scaffold frame 4 is also connected with the scaffold node 1. This connection state can be seen in the cross-sectional view of FIG. 5.

Fig. 5 shows a cross-sectional side view of a part of a scaffold section 100 according to an embodiment of the present invention. FIG. 5 shows, in a sectional view, a part of the scaffold section 100 also shown in FIG. 4 in the installed state. It can be seen in FIG. 5 that the two connecting ends 411 of the upper scaffold frame 4 and the lower scaffold frame 4 are introduced into the connecting sleeve 2. The end sides or end surfaces of the two connecting end portions 411 abut each other here and lie up and down together. This makes it possible to directly transmit the force in the vertical direction between the two end sides of the connecting end 411. Optionally, a protrusion may be provided inside the connecting sleeve 2, and the end side of the connecting end abuts against the protrusion. In this case, the force in the vertical direction is first transmitted from the connecting end 411 to the scaffold node 1 through the protrusion. In a further process, the force is transferred from the scaffold node 1 to the end side of the second connecting end 411 through the protrusion. It can also be seen in FIG. 5 that the corresponding locking opening 26 and the corresponding fixing opening 412 are aligned with each other or arranged equally. In the state shown, in order to establish a form-fitting connection, the plug element 7 can be inserted into the corresponding locking opening 26 and the fixing opening 412. The corresponding plug-in element 7 is also shown to be aligned with the opening next to the scaffold node 1. This pinning between the scaffolding node and the scaffolding frame prevents the scaffolding frame 4 from being unintentionally pulled out of the scaffolding node 1 or falling out therefrom. However, for the installation of the scaffold section 100, such pinning is not mandatory.

Fig. 6 shows a perspective view of a scaffold node 1 according to another embodiment of the present invention. The difference between the embodiment shown in FIG. 6 and the embodiment shown in FIG. 1 is that the connecting sleeve 2 has only one gap 22. The slit 22 has a slit length SL, which exceeds half of the overall sleeve length 24. In this embodiment, the slit 22 also opens into the end opening 23. In this embodiment, the scaffold node 1 also has a coupling element 3, which is realized here as a connecting plate 31. The coupling element 3 surrounds the connecting sleeve 2 in only a partial area in the circumferential direction of the connecting sleeve 2. The coupling element 3 is interrupted in the circumferential area of the connecting sleeve 2 in which a gap 22 is provided. Thus, the coupling element 3 does not prevent the frame crossbar 42 from being introduced into the gap 22 in. Here, the coupling element 3 is arranged in the middle with respect to the overall sleeve length 24. The slit 22 extends in the longitudinal direction of the connecting sleeve 2 through the area in which the coupling element 3 is fixed at the outer periphery of the connecting sleeve 2. Therefore, the gap length SL is greater than the distance from the end face 27 of the connecting sleeve to the middle of the coupling element 3. In the embodiment of the scaffold node 1 shown in FIG. 6, it is proposed to be coupled with only one scaffold frame 4. The connecting end 411 of the scaffold frame 4 can be introduced into the upwardly facing end opening 23, wherein the frame cross bar 42 of the scaffold frame 4 is introduced into the gap 22. The scaffold frame 4 can be introduced into the connecting sleeve 2 until the frame cross bar 42 is stopped at the downward facing end of the gap 22. In this state, the scaffold node 1 and the scaffold frame 4 can be positioned correctly with each other. The embodiment shown in Fig. 6 has two locking openings 26, which fulfill the same functions as in the previous embodiment. The coupling element 3 of the embodiment shown in FIG. 3 is another scaffold element, especially a modular scaffold component 6, which can be coupled in the same manner as the other embodiments described above. For the embodiment shown in FIG. 6, the relative position of the formed scaffold frame 4 and the scaffold node 1 is different from the foregoing embodiment. This can be seen in Figure 7.

Fig. 7 shows a perspective view of a part of another embodiment of the scaffold section 100 according to the present invention. Fig. 7 shows a scaffold node 1 according to the embodiment of Fig. 6 with a scaffold frame 4 inserted into the scaffold node 1 from above. The connecting end 411 of the vertical rod 41 is introduced into the connecting sleeve 2 until the downward facing surface of the frame cross rod 42 is stopped at the downward facing end of the gap 22. It can be seen that the locking opening 26 of the connecting sleeve 2 is positioned to be equal to or aligned with the fixing opening 412 of the connecting end 411. In the state shown in FIG. 7, the plug-in element 7 can be introduced into the locking opening 26 and the fixing opening 412, and therefore the scaffold node 1 and the scaffold frame 4 are pinned together. As can be clearly seen in FIG. 7, in the coupled state, the central axis of the frame cross bar 42 is arranged to the middle of the coupling element 3 in the longitudinal direction of the coupling sleeve 2. Therefore, the frame cross bar 42 is positioned to the same height as the coupling element 3. On the contrary, for the In the embodiment shown in, there is a distance in the longitudinal direction of the connecting sleeve 2 between the coupling element 3 and the frame cross bar 42. The relative connection position for the modular scaffolding part 6 (which is provided by the coupling element 3) is different between the embodiments. This fact can be used to combine and connect scaffold frames 4 with different sizes and grid sizes to each other.

Fig. 8 shows a perspective view of an embodiment of a scaffold node 1 according to an embodiment of the present invention. In the embodiment of the scaffold node 1, the coupling element 3 is not formed by the connecting plate 31 like in other embodiments. The embodiment of the scaffold node 1 shown has a connecting sleeve 2 similar to the connecting sleeve 2 of other embodiments. In order to connect with other scaffold elements, the illustrated embodiment has two cup-shaped lock elements 301a and 301b, which form the coupling element 3. Between the two cup-shaped lock elements 301a and 301b, the horizontal beam 304 (which is the modular scaffold part 6) is connected to the scaffold node 1, which faces the left and front in the view. The connecting sleeve 2 is arranged in the same manner as the previous embodiment, so that the vertical rod 41 is pushed into the connecting sleeve 2 from above and below. The two cup-shaped lock elements 301a and 301b are constructed in the form of rims. The two cup-shaped lock elements 301a and 301b are designed to be rotationally symmetrical about the central axis. The central axis coincides with the central axis MA of the connecting sleeve 2. The cup-shaped lock element 301 a further arranged under the connecting sleeve 2 has an inner diameter on its side facing downward, and the inner diameter roughly corresponds to the outer diameter of the connecting sleeve 2. In contrast, the upper inner diameter of the cup-shaped lock element 301a is selected to be larger, so that there is a distance or gap between the inner diameter of the cup-shaped lock element 301a and the outer diameter of the connecting sleeve 2 in the upward direction. . The end pieces of the horizontal beam 304 are introduced into this gap. The cup-shaped lock element 301a arranged in the lower part is fixedly connected to the connecting sleeve in its lower region. The cup-shaped lock element 301b arranged at the upper part corresponds to the cup-shaped lock element 301a arranged at the lower part. However, the cup-shaped lock element 301b arranged on the upper part is not fixedly connected to the connecting sleeve 2, but is installed to be axially displaced relative to it. In order to connect with the horizontal beam 304, first (as shown in FIG. 8), the upper cup-shaped lock element 301b relative to the connection The sleeve 2 is pushed up. As a result, a greater distance is created between the two cup-shaped lock elements 301a and 301b. In the state shown, the horizontal beam 304 is inserted into the gap between the lower cup-shaped lock element 301a and the outer wall of the connecting sleeve 2 with a correspondingly formed end region. Finally, the upper cup-shaped lock element 301b is pushed down along the connecting sleeve 2, so that the gap between the inner diameter of the upper cup-shaped lock element 301b and the outer diameter of the connecting sleeve 2 also surrounds the horizontal beam 304 The upper part of the end area. In this state, the two cup-shaped lock elements 301a and 301b are pushed together and surround the end area of the horizontal beam 304, which is fixedly connected to the scaffold node 1.

Fig. 9 shows a perspective view of an embodiment of a scaffold node 1 according to an embodiment of the present invention. In this embodiment, there is no land 31 either. On the contrary, in order to connect with other scaffold elements, the disc 303 as the connecting element 3 is fixedly connected with the connecting sleeve 2. For the embodiment shown, the disc 303 is mounted in the middle of the connecting sleeve. A plurality of substantially wedge-shaped grooves are formed on the disc 303, and these grooves penetrate the disc 303. These grooves are used to connect other scaffolding elements, in particular to the modular scaffolding part 6, such as the horizontal beam 305 oriented toward the left and front here. The disc 303 has an edge protruding in the longitudinal direction of the connecting sleeve 2 on its outer periphery. The horizontal beam 305 has an end region, which at least partially corresponds to the female mold of the shape of the disc 303. As a result, the end region can be connected to the disk 303 in a form-fitting manner. Therefore, in order to fix the horizontal beam 305 on the scaffold node 1, the beam element is inserted into the end region of the horizontal beam 305. The crossbar element penetrates the end region and penetrates one of the grooves in the disc 303. As a result, the horizontal beam 305 is more firmly fixed on the disc 303 and thus on the scaffold node 1.

Fig. 10 shows a perspective view of an embodiment of a scaffold node 1 according to an embodiment of the present invention. In the embodiment of the scaffold node 1 shown, there is also no connection plate 31. In order to connect other scaffold elements, in the illustrated embodiment, the four wedges of the coupling element 3 The lock pockets 302 are evenly arranged on the circumference of the outer surface of the connecting sleeve 2. A horizontal beam 306 can be seen to the left and front, and the horizontal beam 306 has an end region facing the connecting sleeve 2. This area is realized as a wedge shape and matches the wedge lock pocket 302. In order to connect the horizontal beam 306 with the scaffold node 1, the wedge-shaped end area of the horizontal beam 306 is introduced into the wedge-shaped lock pocket 302. Through the wedge shape of the end region, the horizontal beam 306 is clearly positioned in the wedge lock pocket 302 and fixed therewith. In the illustrated embodiment, the four wedge-shaped lock pockets 302 are arranged evenly (which means that there is a constant distance between each other) around the circumference of the connecting sleeve 2. Here, the wedge-shaped lock bag 302 is made of a metal plate and is welded to the connecting sleeve 2.
