Definitions

  • the invention relates to a scaffolding node for connecting scaffolding components running in different spatial directions, comprising a connecting sleeve which is provided as a coupling point for two vertical posts or for a vertical post with a spindle nut post and at least one coupling element which is used to connect the scaffolding node to scaffolding components or scaffolding elements.
  • the invention further relates to a scaffolding section with a scaffolding node and further scaffolding elements.
  • Scaffolding is used in the construction sector for various tasks. Facade scaffolding is used to design the exterior surfaces of buildings, for example to paint them. In civil engineering, scaffolding or shoring is used to bring a wide variety of building parts into position and hold them there. Such building parts can be, for example, prefabricated concrete parts, steel beams or steel structures. Furthermore, elements required for the construction of structures such as temporary structures or formwork with supporting scaffolding can be positioned. Finally, scaffolding is also used in the service or inspection area, for example to bring workers safely to the parts of the system that need to be overhauled in large process engineering plants, such as refineries. In general, the basic requirements for scaffolding are that they must be easy to transport and easy to assemble.
  • scaffoldings When constructing scaffolding, vertical elements, horizontal elements and usually diagonal elements must be connected to one another to form a load-bearing structure.
  • scaffoldings which have devices on their vertically extending elements which enable the connection of other elements, for example horizontally extending elements.
  • the disadvantage of this solution is that these vertical elements have a relatively complicated structure.
  • these vertically extending elements are bulky and therefore difficult to transport due to the device for connecting additional scaffolding elements.
  • scaffolding elements are on a construction site from different manufacturers and from different years of construction should be mixed together to form a scaffolding. The problem often arises that scaffolding elements from different manufacturers have different quality and different dimensional tolerances.
  • EP1013849A1 reveals a scaffold node.
  • the object of the invention is therefore to propose a solution to be able to securely connect scaffolding elements with different dimensional tolerances to one another and at the same time to enable a quick and safe construction of a scaffold.
  • the object of the invention is achieved by a scaffold node according to claim 1.
  • a scaffold node according to the invention comprises a connecting sleeve, which is usually vertically aligned in the application, and a coupling element arranged on this connecting sleeve.
  • the term use case is understood to mean the state in which the scaffolding node is installed in a scaffolding and is used to connect several scaffolding elements.
  • the term use case also includes the construction or dismantling of a scaffolding with a scaffolding node.
  • the connecting sleeve is used to connect vertical scaffolding elements.
  • Such vertically extending scaffolding elements are, for example, vertical posts.
  • Such a vertical stem can also be formed by a simple tube that is hollow on the inside.
  • the connecting sleeve can be formed, for example, by a simple pipe section.
  • the connecting sleeve serves as a coupling point between the vertically oriented scaffolding elements in the application.
  • two vertically extending scaffolding elements are inserted into the connecting sleeve, they are coupled together by the connecting sleeve.
  • a spindle nut handle is also possible to insert into the connecting sleeve and to couple it there with a vertical handle. Such a spindle nut handle is described in more detail below in connection with a scaffolding section according to the invention.
  • a scaffolding node according to the invention further comprises a coupling element which serves to connect the scaffolding node to scaffolding components or scaffolding elements.
  • the coupling element is connected to or attached to the connecting sleeve.
  • the coupling element can be designed in various ways.
  • the coupling element is used to connect the scaffolding node to scaffolding components or scaffolding elements that do not run vertically in the application. In the application, the scaffolding components or scaffolding elements attached to the coupling element usually run horizontally or diagonally in the scaffolding.
  • the coupling element is firmly connected to the connecting sleeve.
  • the connecting sleeve is usually essentially cylindrical in shape and hollow inside.
  • the inner surface of the connecting sleeve is referred to as the inner lateral surface.
  • the outer surfaces of these vertically extending scaffolding elements lie parallel to the inner lateral surface of the connecting sleeve.
  • a scaffold node according to the invention comprises at least one inner projection which protrudes radially in the direction of the interior of the connecting sleeve over the inner lateral surface.
  • This inner projection is essential for the function of the scaffolding node according to the invention.
  • Vertically running scaffolding elements such as vertical posts, have dimensional tolerances in their external dimensions. The more cost-effectively these vertical scaffolding elements are manufactured, the greater the tolerances in their external dimensions. When setting up a scaffolding, these dimensional tolerances create problems with securely positioning and coupling the vertical scaffolding elements to one another and thus achieving a targeted force connection in the scaffolding. Because the inner projection protrudes beyond the inner lateral surface, an introduced vertically extending framework element lies against the inner projection. The inner projection projects suddenly from the inner lateral surface of the connecting sleeve. This means that the inner projection can or is present as a sharp-edged, in particular not continuous, transition between the inner lateral surface and the inner projection.
  • the inner projection according to the invention has at least one load-receiving surface, which is intended to accommodate loads from a scaffolding component that are oriented in the longitudinal direction of the connecting sleeve.
  • the load-bearing surface is usually flat.
  • vertically extending scaffolding elements inserted into the scaffolding nodes, in particular into the connecting sleeve rest the load-bearing surface of the at least one, abruptly protruding inner projection.
  • the load-bearing surface has a projection height from its outer edge adjacent to the inner lateral surface to its inner edge, which is oriented radially towards the interior of the connecting sleeve. This projection height is chosen so that vertical scaffolding elements such as vertical posts always rest on the load-bearing surface, despite tolerances in their dimensions.
  • the projection height is advantageously chosen so that even vertically extending scaffolding elements with a smaller outer diameter than the inner diameter of the connecting sleeve still rest on the load-bearing surface with a sufficient contact surface and thus a safe force transmission in the vertical direction from the vertically extending scaffolding element to the scaffolding node is always guaranteed.
  • the inner projection thus projects suddenly over the inner lateral surface. Due to this sudden protrusion of the inner projection, it is suitable for vertically extending scaffolding elements inserted into the connecting sleeve to rest on this inner projection.
  • the vertically extending scaffolding elements thus transmit forces and loads directed in the vertical direction to the inner projection of the scaffolding node. These forces and loads are thus introduced into the scaffolding nodes.
  • the inner projection in the described embodiments has a load-bearing surface.
  • this load-bearing surface is oriented at right angles to the inner lateral surface of the connecting sleeve.
  • the load-bearing surface can also be aligned at an angle to the inner lateral surface.
  • a certain width of the load-bearing surface which corresponds to the projection height of the inner projection, is required. It has turned out to be particularly favorable that Projection height is equal to or greater than the wall thickness or wall thickness of the connecting sleeve. Such a projection height ensures that a vertically extending scaffolding element subject to tolerances, which is inserted into the connecting sleeve, rests securely and stably on the load-bearing surface.
  • Horizontal loads can be introduced into the scaffolding nodes according to the invention via the coupling element.
  • horizontally extending scaffolding elements that are connected to the scaffolding node are usually designed in such a way that they touch the outer surface of the connecting sleeve when assembled. This means that moments from connected horizontally running scaffolding elements can also be introduced into the scaffolding nodes.
  • a scaffolding node according to the invention offers several advantages over the prior art:
  • the scaffolding node has a very simple structure and has compact dimensions. This means that the scaffold node can be produced in a simple manner and is easy to transport.
  • a scaffolding node according to the invention enables the use of other scaffolding elements that are also very simply constructed.
  • the scaffolding node performs the function of connecting or coupling scaffolding elements that are oriented in different directions. This function of the connection therefore does not have to be provided on the scaffolding elements themselves.
  • the vertically extending scaffolding elements which in the prior art have devices for connecting other scaffolding elements, can be made much simpler when using a scaffolding node according to the invention.
  • Vertical scaffolding elements for example vertical posts, can be formed from simple pipe sections. Such pipe sections can easily be made from standard material. Depending on individual needs, a wide variety of lengths of vertical scaffolding elements can be easily connected to the scaffolding node. This results in a very simple adjustment of the scaffolding height or the distance between two scaffolding platforms.
  • the vertical scaffolding elements formed from simple pipe sections can also be stored and transported very easily because they do not have any elements that protrude outwards. Scaffolding elements running in other spatial directions can also be connected to a scaffolding node according to the invention.
  • This option makes it possible to quickly and easily build two-dimensional and three-dimensional scaffolding structures using a scaffolding node made up of one-dimensional scaffolding elements.
  • One-dimensional scaffolding elements are understood to mean rod-shaped or tubular elements.
  • horizontal and diagonal scaffolding elements are sometimes assembled to form prefabricated, two-dimensional frames. These prefabricated frames are then connected to vertical scaffolding elements using devices, creating the required three-dimensional scaffolding structure.
  • the disadvantage of this concept with prefabricated frames is that these frames are significantly bulkier than one-dimensional scaffolding elements.
  • a scaffold node according to the invention eliminates the need to provide two-dimensional prefabricated frames.
  • a wide variety of one-dimensional scaffolding elements can be connected to the scaffolding node very quickly and easily and the required three-dimensional scaffolding structure can be created directly from one-dimensional scaffolding elements on site at the construction site. This makes transporting the required scaffolding elements to the construction site easier and more economical, as the one-dimensional scaffolding elements can be transported with a significantly higher packing density than two-dimensional structures such as frames.
  • a scaffold node according to the invention makes transport of a scaffold significantly easier and at the same time enables a simple and yet very adaptable construction of three-dimensional scaffold structures.
  • a scaffold knot according to the invention can also be referred to as a knot sleeve.
  • the projection height is equal to or greater than the wall thickness of the connecting sleeve. Such a projection height ensures that vertically extending scaffolding elements can safely come into operative connection with the load-bearing surface of the abruptly protruding inner projection over an entire, wide tolerance range and that vertically extending loads are always safely transferred to the scaffolding node.
  • the coupling element is designed as a connecting disk, wherein the connecting disk has a receiving surface with a plurality of receiving recesses and the receiving recesses are intended to be connected to further scaffolding elements, such as horizontal bars or diagonal struts, and the connecting disk is firmly connected to the connecting sleeve and the receiving surface is essentially perpendicular to the Total length of the connecting sleeve is aligned.
  • the connecting disk has a receiving surface. This receiving area is the largest area of the connecting disk.
  • the receiving surface is usually significantly larger than the side surfaces of the connecting disk.
  • the receiving surface is essentially oriented at right angles to the axis of symmetry or to the total length of the connecting sleeve.
  • Several receiving recesses are arranged in the receiving surface, which serve to connect to other scaffolding elements. These other framework elements are usually positively connected to the connecting disk and in particular to the surfaces of the receiving recesses and the receiving surface.
  • the coupling element is formed by two cuplock elements, which are constructed in the shape of a collar, with one cuplock element being firmly connected to the connecting sleeve and that another cuplock element is mounted axially displaceable relative to the connecting sleeve and there is a gap between an inner diameter of the cuplock elements and the outer diameter of the connecting sleeve into which an end piece of a horizontal strut can be inserted.
  • the coupling element of the scaffold node is formed by two cuplock elements. These cuplock elements can also be used to connect other scaffolding components or elements, which in particular run horizontally or diagonally in the application, to the scaffolding node.
  • cuplock elements are collar-shaped, which means that they have a smaller diameter at one end than at the opposite ends.
  • One of the cuplock elements is firmly connected to the connecting sleeve, the other cuplock element is arranged on the connecting sleeve in an axially displaceable manner.
  • the axially displaceable cuplock element is moved away from the axially fixed cuplock element.
  • An end piece of a connecting element for example a horizontal strut, is then inserted between the two cuplock elements.
  • the coupling element is formed by several, in particular four, wedge locking pockets, wherein a wedge-shaped end region of a horizontal strut fits into a wedge locking pocket and the wedge-shaped end region of the horizontal strut can be inserted into the wedge locking pockets and fixed there.
  • scaffolding elements are designed as several wedge locking pockets Coupling element connected to the scaffold node.
  • Such a scaffolding element can be formed, for example, by a horizontal strut which has an end region which has the shape of a wedge.
  • Several wedge locking pockets are provided as a coupling element, which form the negative shape of the wedge-shaped end region of the horizontal strut.
  • the wedge-shaped end region of the horizontal strut is simply inserted into the correspondingly shaped wedge locking pocket, which creates a positive connection between the horizontal strut and the coupling element.
  • This positive fit fixes the horizontal strut to the scaffolding node.
  • several wedge locking pockets are provided, which are arranged at regular intervals or angles around the circumference of the connecting sleeve.
  • the coupling element is formed by a plate washer, which is firmly connected to the connecting sleeve and the plate washer has a plurality of substantially wedge-shaped recesses which penetrate the plate washer, the wedge-shaped recesses being intended to be horizontal running scaffolding elements, such as a horizontal strut.
  • a plate washer is usually designed as a circular ring and represents an alternative embodiment of a coupling element. The plate washer is firmly connected to the connecting sleeve and rotates around it. The plate disk has several wedge-shaped recesses which are provided for a positive connection to another framework element, for example a horizontal strut.
  • Such a horizontal strut has an end piece corresponding in cross section to such a wedge-shaped recess, which can be inserted in a form-fitting manner into the plate washer, whereby the horizontal strut is firmly fixed to the coupling element designed as a plate washer.
  • the divider disk has an edge which protrudes on its outer circumference in the longitudinal direction of the connecting sleeve. This edge enables an additional positive connection with the horizontal strut and thus improves the security of the connection between the scaffolding element and the scaffolding node.
  • the at least one inner projection is a part of the connecting disk, wherein the connecting disk divides the connecting sleeve into two parts and the end face of a part of the connecting sleeve is firmly connected to a receiving surface of the connecting disk.
  • the inner projection is formed by a part of the connecting disk.
  • the connecting sleeve is designed in two parts. One part of the connecting sleeve is firmly connected at the end to a receiving surface of the connecting disk.
  • the connecting disk thus extends into the interior of the connecting sleeve and forms the inner projection there.
  • This embodiment has the further advantage that vertical scaffolding elements inserted into the connecting sleeve are in direct contact with the horizontally extending connecting disk. This ensures a good flow of force through the scaffold node, even in a horizontal or diagonal direction.
  • the connecting disk has a particularly circular recess and at least a partial area outside this recess forms the inner projection.
  • a recess is conveniently provided in the middle of the connecting disk. This recess serves to enable vertically extending scaffolding elements to be pushed through the entire interior of the connecting sleeve. This is particularly important if a spindle nut handle is to be inserted into the scaffolding node in conjunction with a scaffolding spindle. The scaffolding spindle can then be moved vertically through the recess in the connecting disk.
  • Vertical scaffolding components or scaffolding elements that directly transmit a load such as a Vertical handle or a handle shaft of a spindle nut handle have a larger diameter than the recess in the connecting disk and therefore cannot be moved through this recess.
  • the recess in the connecting disk is not intended for such scaffolding elements to be pushed through.
  • the vertically load-bearing scaffolding elements come into contact with the jump-like inner projection arranged around the recess and transfer vertical loads to the scaffolding node as described above.
  • the edge of the recess in the connecting disk simultaneously forms the inner projection inside the connecting sleeve. The projection height or width of the inner projection can thus be adjusted by dimensioning the recess in the connecting disk.
  • the shape and diameter of the recess in the connecting disk is very easy to produce and influence, since the connecting disk is a flat component that can be easily processed by punching, laser cutting, drilling or similar. This embodiment therefore combines the advantages of a simple structure with cost-effective production.
  • the connecting sleeve is made in one piece and the inner projection is formed by an impression running radially around the circumference of the connecting sleeve and the connecting disk is fastened to the outer lateral surface of the connecting sleeve.
  • an inner projection which protrudes suddenly over the inner lateral surface of the connecting sleeve, is also realized by molding the wall of a one-piece connecting sleeve. For this purpose, an impression running around the circumference is created in the connecting sleeve. This impression then projects inwards and forms the inner projection, which also has a load-bearing surface.
  • loads and forces from an inserted vertical scaffolding element can then be introduced into the connecting sleeve and thus into the scaffolding node via this load-bearing surface created by an impression.
  • the inner projection formed by molding the wall also has a discontinuous, abrupt transition from the inner lateral surface to the load-bearing surface.
  • Such an embossed, jump-like transition can be achieved using appropriately sharp-edged embossing tools that are used to form the wall.
  • This embodiment has a simpler structure because it includes a one-piece connecting sleeve.
  • the circumferential impression represents a massive deformation of the wall of the connecting sleeve, so that an appropriate device must be available for such an impression.
  • the connecting disk is attached to the connecting sleeve from the outside and does not divide the connecting sleeve into two parts.
  • At least one further inner projection is formed by molding the wall of the connecting sleeve, the inner projection inside the connecting sleeve having a constant projection height in the longitudinal direction of the connecting sleeve or the inner projection starting from the inner lateral surface of the connecting sleeve continuously up to the projection height rises and falls.
  • a further inner projection is provided which does not have a sudden transition to the inner lateral surface. This further inner projection is formed by a molding in the wall of the connecting sleeve.
  • a corresponding embossing tool is used, which creates an inner projection with a continuous transition to the inner lateral surface.
  • the term “wall” refers to the wall of the tubular connecting sleeve.
  • Such a shaping can be done, for example, by embossing or punching.
  • the further inner projection consists of a portion of the connecting sleeve, which receives its shape through a forming process.
  • a pipe section made of a metal material is usually used as the base and the further inner projection is then used shaped into the wall.
  • a connecting sleeve with such a further internal projection can therefore be produced very easily from inexpensive base material.
  • the further internal projection runs along the entire length of the connecting sleeve and has a constant projection height.
  • the projection height is to be understood as the amount by which the point of the inner projection that extends furthest into the interior of the connecting sleeve protrudes beyond the inner lateral surface.
  • Both the inner projection, which protrudes abruptly over the inner lateral surface, and the further inner projection have a projection height.
  • the further inner projection does not run along the entire total length, but rather extends over only part of the connecting sleeve in relation to the length. In this embodiment there is a smooth transition between the inner lateral surface and the further inner projection. Starting from the inner lateral surface, the projection height rises steadily to the greatest projection height and on the other side of the projection height falls steadily again to the inner lateral surface.
  • the further inner projection of a scaffolding node ensures that vertical scaffolding elements inserted into the connecting sleeve are centered. Particularly favorable for this centering is the provision of several additional internal projections, which then work together during centering.
  • One or more further internal projections can be arranged specifically at convenient locations inside the connecting sleeve in order to achieve the desired centering of the vertically extending framework elements in the connecting sleeve.
  • the centering achieved ensures that two vertical scaffolding elements, one of which is inserted into the scaffold node from each side, are aligned with each other, thus enabling good and efficient force dissipation of vertical loads.
  • the at least one further inner projection is designed as a longitudinal bead, which extends over the entire length of the Connecting sleeve extends.
  • the further inner projection has a constant projection height.
  • Such a further inner projection, designed as a longitudinal bead can be produced simply by stamping it into the connecting sleeve from the outside.
  • Such a further inner projection guides vertically extending framework elements inserted into the connecting sleeve along the entire length of the connecting sleeve.
  • the provision of three or more such further internal projections is particularly advantageous, since a larger number of further internal projections further significantly improves the centering effect on the inserted framework elements.
  • two, advantageously three, particularly preferably four further internal projections designed as longitudinal beads are provided, which are evenly distributed in the circumferential direction on the inner lateral surface.
  • a uniform distribution of several additional internal projections in the circumferential direction inside the connecting sleeve is particularly favorable for good centering of introduced scaffolding elements in the scaffolding node.
  • the connecting sleeve is made in one piece and the connecting disk is fastened, in particular welded, to the outer lateral surface of the connecting sleeve.
  • a particularly simple structure of a scaffold node is achieved in the embodiment described by a one-piece connecting sleeve with a connecting disk firmly connected to it.
  • the at least one further inner projection is designed as an embossing point, which has an embossing center and which, starting from the inner lateral surface, rises steadily in all radial directions around the embossing center up to the projection height, the projection height being in the embossing center.
  • the further inner projection is also formed by molding the wall of the connecting sleeve. This indentation is made by embossing with a pointed embossing tool. This creates an embossing point executed further internal projection inside the connecting sleeve. This forming process creates a continuous transition between the inner surface and the further inner projection, which is designed as an embossing point.
  • the further inner projection has an embossing center at which the projection height is greatest. All around the embossing center, the height of the projection drops steadily down to the inner surface. Due to these gentle transitions, such a further inner projection is particularly well suited to guiding a scaffolding element inserted into the connecting sleeve, such as a vertical handle. Starting from the inner lateral surface, the scaffolding element slides gently over the further inner projection and is thus centered when inserted into the connecting sleeve.
  • the production of a further inner projection designed as an embossing point is also particularly simple, since, starting from a tubular connecting sleeve, only a simple embossing tool is required to produce the further inner projection. No further components are required.
  • several further internal projections designed as embossing points are provided, which are arranged in at least two rings, the rings being aligned parallel to the receiving surface of the connecting disk and the rings being spaced apart from one another and the further internal projections along the rings in the circumferential direction are evenly distributed on the inner surface.
  • several further internal projections are provided, which together guide and center a framework element inserted into the connecting sleeve.
  • the further inner projections are arranged in rings which run parallel to the connecting disk and parallel to the front ends of the connecting sleeve.
  • the rings are not structural elements, but merely imaginary auxiliary lines to describe the arrangement of the other internal projections.
  • the further internal projections are arranged opposite one another inside the connecting sleeve. This results in the maximum projection heights of the further inner projections defining a clear width inside the connecting sleeve, which is smaller than the inner diameter of the connecting sleeve from a point on the inner lateral surface to a point on the inner lateral surface opposite this point. Further internal projections arranged in this way reduce the clear width inside the connecting sleeve.
  • each of the rings is arranged at one end of the connecting sleeve and two further rings being arranged adjacent to the connecting disk.
  • four rings of further internal projections are provided. Based on the total length of the connecting sleeve, two rings are arranged in each half of the connecting sleeve. One ring of this is arranged near the front end of the connecting sleeve, and another is arranged adjacent to the connecting disk.
  • the connecting sleeve is made in one piece and the connecting disk is fastened, in particular welded, to the outer lateral surface of the connecting sleeve.
  • a scaffold node which has both at least one inner projection that protrudes abruptly over the inner lateral surface of the connecting sleeve and at least one further inner projection that does not project abruptly, have particular advantages.
  • Vertically extending loads are initially introduced directly into the scaffolding node via the abruptly protruding inner projection from a vertically extending scaffolding element, which is inserted into the scaffolding node. These loads are then transferred from the scaffolding node via the abruptly protruding inner projection to another, vertically extending scaffolding element.
  • a correspondingly favorably selected projection height of the abruptly protruding inner projection ensures that that the loads of vertically extending scaffolding elements are safely transferred to and from the jump-like inner projection in every tolerance position of the external dimensions of these scaffolding elements.
  • Another inner projection that is not abrupt, in particular not sharp-edged helps to center the vertically extending scaffolding elements inserted into the scaffolding node.

Please also refer to the description of this connection Fig. 1 referred.
  • a spindle nut handle 304 Above scaffold node 1 is in Fig. 14 a spindle nut handle 304 can be seen.
  • This spindle nut handle 304 has a handle shaft 3041 in its lower area. This handle shaft 3041 has an outer diameter that is slightly smaller than the clear width of the connecting sleeve 2 of the scaffold node 1.
  • the handle shaft 3041 can thus be inserted into the connecting sleeve 2 in the same way as a vertical handle 41.
  • a spindle nut 3042 is arranged, which is firmly connected to the handle shaft 3041.
  • Both the handle shaft 3041 and the spindle nut 3042 are hollow on the inside.
  • a scaffolding spindle 800 can be seen above the spindle nut handle 304. This scaffolding spindle 800 has an external thread which matches the internal thread which is arranged in the axial direction inside the spindle nut 3042. The scaffolding spindle 800 can thus be screwed into the spindle nut handle 304.
  • the elements scaffolding node 1, spindle nut handle 304 and scaffolding spindle 800 are connected to one another as follows: first, the handle shaft 3041 is inserted into the connecting sleeve 2. This connection is not secured with a plug-in element 5 because the spindle nut handle 304 is intended to be rotatably mounted in the scaffolding node 1. In this state, on the downward-facing side, a vertical stem 41 is already inserted into the scaffolding node 1 and secured with a plug-in element 5. After the handle shaft 3041 has been inserted into the connecting sleeve 2, its downward-facing end face rests on the upward-facing end face of the vertical handle 41 and is supported this one off.
  • the scaffolding spindle 800 is inserted into the spindle nut handle 304 from above.
  • the spindle nut handle 304 is rotated, whereby the two threads interlock and pull the scaffolding spindle 800 into the spindle nut handle 304.
  • a mounted scaffolding section 100 then has the very practical functionality that the scaffolding spindle 800 can be varied and adjusted in its position relative to the connecting sleeve 2 by turning the spindle nut handle 304.
  • the scaffolding section 100 shown has a simple structure, is robust and consists of parts that are easy to manufacture. All built-in components are compact and therefore easy to transport. Since the outer diameter of the handle shaft 3041 corresponds to the outer diameter of a vertical handle 41, a spindle nut handle 304 can of course also be inserted into a scaffold node 1 from below. An embodiment is also conceivable in which a spindle nut handle 304 is inserted into the connecting sleeve 2 on both sides. Furthermore, it is possible to Fig. 14 to combine the spindle nut handle 304 shown with one of the other described embodiments of a scaffold node, in particular with the second and third embodiments.
  • Fig. 15 shows a sectioned side view of a scaffolding section 100 not according to the invention with a spindle nut handle 304.
  • the elements are off Fig. 14 shown connected to each other. Scaffolding node 1 can again be seen in the center.
  • the horizontal bar 42 is connected to the scaffold node 1.
  • a vertical stem 41 is inserted from below into the connecting sleeve 2 and is inserted approximately up to the middle of the total length 23 of the connecting sleeve 2.
  • a spindle nut stem 304 is inserted into the connecting sleeve 2 from above.
  • the handle shaft 3041 is also approximately up to inserted towards the middle into the connecting sleeve 2.
  • the scaffolding spindle 800 is off Fig. 14 not shown.
  • a scaffolding spindle 800 it is inserted into the spindle nut 3042 from above.
  • the spindle nut handle 304 is rotated, as a result of which the scaffolding spindle 800 moves in the vertical direction relative to the scaffolding node 1.
  • the scaffolding spindle 800 can penetrate into the hollow interior of the handle shaft 3041 and the vertical handle 41.
  • a relative movement takes place from the downward-facing end face of the spindle nut handle 304 relative to the upward-facing end face of the vertical handle 41.
  • a spindle nut handle 304 can of course also be introduced into scaffolding node 1 according to the second embodiment not according to the invention or an embodiment according to the invention .
  • the end of the handle shaft 3041 facing away from the spindle nut 3042 is supported on the load-bearing surface 251 of the inner projection 25.
  • FIG. 16 shows a sectioned side view of a scaffolding section 100 according to the invention with two inserted vertical posts 41.
  • a scaffolding node 1 according to the invention is centrally arranged, into which a vertical post 41 is inserted from above and from below.
  • the front ends of these vertical stems 41 rest on an internal projection 25 which protrudes abruptly and is arranged circumferentially inside the connecting sleeve 2. Touch while doing so the front surfaces of the vertical posts 41 are the load-receiving surfaces 251 of the inner projection 25. Loads running in the vertical direction are introduced, for example, from the vertical post 41 inserted into the top of the scaffolding node 1 via its front end into the inner projection 25.
  • the vertical loads are then passed on directly to the vertical post 41 inserted into the scaffolding node 1 below, the upward-facing end of which touches the inner projection 25 from below.
  • the inner diameter of the connecting sleeve 2 is slightly larger than the outer diameter of the vertical stems 41.
  • no further inner projections 25a are arranged on the inner lateral surface 26.
  • further inner projections 25a that do not protrude suddenly over the inner lateral surface 26.
  • Such further internal projections 25a are, for example, in the Figs 1 to 7 shown and described.
  • FIG. 16 A horizontal bar 41 is attached to the left of the scaffolding node 1. This fastening is carried out by inserting a shaped element 421 of the horizontal bar 42 into a receiving recess 32 of the coupling element of the scaffold node 1, which is designed as a connecting disk 3.
  • Fig. 17 shows a side view of a scaffolding section 100 according to the invention with a spindle nut handle 304 shown above the scaffolding node 1.
  • a scaffolding node 1 according to the invention is shown centrally, to which a horizontal bar 42 is attached on the left side.
  • a vertical stem 41 is already inserted into the connecting sleeve 2 from below. The front end of this vertical stem 41 abuts inside the connecting sleeve 2 on the inner projection 25 located there.
  • a spindle nut handle 304 can already be seen arranged coaxially to it.
  • This spindle nut handle 304 is designed identically as in Fig. 14 and Fig. 15 .
  • Fig. 18 shows a perspective view of a scaffolding section 100 according to the invention with an inserted spindle nut handle 304.
  • the spindle nut handle 304 is inserted from above into the connecting sleeve 2 of the scaffold node 1.
  • the handle shaft 3041 is longer than the area of the connecting sleeve 2, which extends in the longitudinal direction from the inner projection 25 (which is arranged at the same height as the connecting disk 3) to the upper end of the connecting sleeve 2. This ensures that that the front end of the handle shaft 3041 always rests on the load-bearing surface 251 of the inner projection 25.
  • Fig. 19 shows a sectioned side view of a scaffolding section 100 according to the invention with an inserted spindle nut handle 304.
  • the in Fig. 18 shown condition can be seen cut from the side.
  • the downward-facing, front end of the handle shaft 3041 rests on the inner projection 25 from above.
  • the lower side of the inner projection 25 rests on the upward-facing end of the vertical stem 41. This ensures a direct flow of force from the spindle nut stem 304 through the abruptly protruding inner projection 25 to the vertical stem 41 arranged below.
  • a circular recess 39 is arranged in the middle of the coupling element designed as a connecting disk 3.
  • This circular recess 39 is surrounded by the inner projection 25.
  • a scaffolding spindle not shown here, can be screwed into the spindle nut 3042. This screwed-in scaffolding spindle can first be guided through the hollow interior of the handle shaft 3041. Furthermore, the scaffolding spindle can then be guided through the circular recess 39 past the inner projection 25 into the vertical handle 41 inserted from below into the scaffolding node 1, which is also hollow on the inside.
  • a scaffolding node 1 with two types of internal projections namely with at least one abruptly protruding internal projection 25 and at least one further internal projection 25a are thus disclosed and are particularly favorable for centering vertically extending scaffolding elements, such as vertical posts in a scaffolding node 1 or a scaffolding section to score 100.
