  • a scaffold node according to the invention comprises a connecting sleeve, which is usually vertically oriented in the application, and a coupling element arranged on this connecting sleeve.
  • Use case is to be understood as the state in which the scaffold node is installed in a scaffold and is used there to connect several scaffold elements.
  • Use case is also to be understood to mean setting up or dismantling a scaffold with a scaffold node.
  • the connecting sleeve is used to connect vertically extending scaffolding elements.
  • Such vertically extending scaffolding elements are, for example, vertical posts.
  • Such a vertical shaft can also be formed by a simple tube which is hollow on the inside.
  • the connecting sleeve can be formed, for example, by a simple tube section.
  • the connecting sleeve serves as a coupling point between the scaffold elements oriented vertically in the application.
  • two vertically extending scaffolding elements are inserted into the connecting sleeve, they are coupled to one another by the connecting sleeve.
  • a spindle nut stem is also possible according to the invention to insert a spindle nut stem into the connecting sleeve and to couple it there with a vertical stem.
  • a spindle nut handle is described in more detail below in connection with a framework section according to the invention.
  • a scaffold node according to the invention further comprises a coupling element which serves to connect the scaffold node to scaffold components or scaffold elements.

  • the coupling element is used to connect the scaffold node with scaffold components or scaffold elements that do not run vertically in the application.
  • the scaffold components or scaffold elements attached to the coupling element usually run horizontally or diagonally in the scaffold in the application.
  • the coupling element is firmly connected to the connecting sleeve.
  • the connecting sleeve is usually essentially cylindrical in shape and hollow on the inside.
  • the inner surface of the connecting sleeve is called the inner lateral surface.
  • vertical scaffolding elements such as vertical posts
  • 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 scaffold node according to the invention.
  • Vertical scaffolding elements such as vertical posts
  • these dimensional tolerances pose problems in securely positioning and coupling the vertically extending scaffold elements to one another and thus achieving a targeted frictional connection in the scaffold.
  • the inner projection protrudes from the inner jacket surface of the connecting sleeve. This means that the inner projection can be or is present as a sharp-edged, in particular non-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 provided for receiving loads oriented in the longitudinal direction of the connecting sleeve from a scaffold component.
  • the load bearing surface is usually flat in itself.
  • vertically extending scaffolding elements are placed in the scaffold nodes, in particular in the connecting sleeve 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 adjoining the inner lateral surface to its inner edge oriented radially in the direction of the interior of the connecting sleeve. This protrusion height is chosen so that vertically extending scaffolding elements such as vertical supports, despite tolerances in their dimensions, always rest on the load bearing surface.
  • the protrusion height is advantageously chosen so that even vertically extending scaffolding elements with a smaller outside diameter than the inside diameter of the connecting sleeve still rest with a sufficient contact surface on the load-bearing surface and thus a secure transmission of force in the vertical direction from the vertically extending scaffolding element to the scaffolding node is always guaranteed.
  • the inner projection in the described embodiments has a load-bearing surface.
  • This load-bearing surface is advantageously oriented at right angles to the inner lateral surface of the connecting sleeve.
  • the load-bearing surface can also be oriented inclined 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 for reliable functioning of the load-bearing surface. It turned out to be particularly favorable that the 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 tolerant, vertically extending scaffold element, which is inserted into the connecting sleeve, rests securely and stably on the load-bearing surface.
  • Horizontal loads can be introduced in the scaffolding node according to the invention on the one hand via the coupling element.
  • horizontally running scaffold elements that are connected to the scaffold node are, on the other hand, designed such that they touch the outer lateral surface of the connecting sleeve in the assembled state. In this way, moments of connected horizontally extending scaffolding elements can also be introduced into the scaffolding node.
  • a scaffold node according to the invention offers several advantages over the prior art:
  • the scaffold node is very simple in construction and has compact dimensions. As a result, 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 of a very simple structure.
  • the scaffold node assumes the function of connecting or coupling scaffold 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 scaffold elements which in the prior art have devices for connecting other scaffold elements, can be made much simpler when using a scaffold node according to the invention.
  • Vertical scaffolding elements for example vertical posts, can be formed from simple pipe sections.
  • Such pipe sections can be easily made from standard material. Depending on individual needs, a wide variety of lengths of vertically extending 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 vertically extending scaffold elements formed from simple pipe sections can moreover be stored and transported very easily, since they have no outwardly projecting elements.
  • Scaffolding elements extending in other spatial directions can also be connected to a scaffolding node according to the invention. With this option, two-dimensional and three-dimensional scaffold structures can be built quickly and easily with a scaffold node made of one-dimensional scaffold elements.
  • One-dimensional scaffolding elements are to be understood as rod-shaped or tubular 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, allowing the required three-dimensional scaffolding structure to be created on site directly from one-dimensional scaffolding elements.
  • a scaffold node according to the invention brings about a significantly simplified transport of a scaffold 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.
  • the coupling element is designed as a connecting disk, the connecting disk having a receiving surface with a plurality
  • Has receiving recesses and the receiving recesses are intended to be connected to other scaffolding elements, such as horizontal bars or diagonal struts, and the connecting disc is firmly connected to the connecting sleeve and the receiving surface is aligned substantially at right angles to the total length of the connecting sleeve.
  • the connecting disk has a receiving surface. This receiving area is the largest area of the connecting disc.
  • the receiving surface is usually significantly larger than the side surfaces of the connecting disk.
  • the receiving surface is oriented essentially at right angles to the axis of symmetry or to the total length of the connecting sleeve.
  • a plurality of receiving recesses are arranged in the receiving surface, which are used for connection to other scaffolding elements. These other scaffolding elements are usually positively connected to the connecting disc 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 form of a collar, one cuplock element being firmly connected to the connecting sleeve, and that another cuplock element is axially displaceably mounted 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 introduced.
  • 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 run horizontally or diagonally, in particular in the application, to the scaffold 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 axially displaceably on the connecting sleeve.
  • the axially displaceable cuplock element is moved away from the axially fixed cuplock element to fasten a scaffold element.
  • an end piece of a connecting element for example a horizontal strut, is inserted between the two cuplock elements.
  • the coupling element is formed by several, in particular four, wedge lock pockets, a wedge-shaped end region of a horizontal strut fitting into a wedge lock pocket and the wedge-shaped end region of the horizontal strut being insertable into the wedge lock pockets and being fixable there.
  • scaffolding elements are designed as a plurality of wedge lock pockets Coupling element connected to the scaffold node.
  • Such a scaffold element can be formed, for example, by a horizontal strut which has an end region which has the shape of a wedge.
  • Several wedge lock pockets are provided as the coupling element, which form the negative form 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 lock pocket, whereby a positive connection is created between the horizontal strut and the coupling element.
  • the horizontal strut is fixed to the scaffold node.
  • a plurality of wedge lock pockets are advantageously 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 is made with a plurality of substantially wedge-shaped recesses which penetrate the plate washer, the wedge-shaped recesses being provided with horizontal extending scaffolding elements, such as a horizontal strut to be connected.
  • a plate washer is usually designed as a circular ring and represents an alternative embodiment of a coupling element. The plate washer is fixed to the connecting sleeve and rotates around it. The plate disk has a plurality of wedge-shaped recesses which are provided for a positive connection with another scaffolding 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 disk, whereby the horizontal strut is firmly fixed to the coupling element designed as a plate disk.
  • the dividing disk advantageously has an edge which projects 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 scaffold element and the scaffold node.
  • the at least one inner projection is part of the connecting disk, the connecting disk dividing the connecting sleeve into two parts and the end face of a part of the connecting sleeve being firmly connected to a receiving surface of the connecting disk.
  • the inner projection is formed by part of the connecting disk. This differs from the previously described embodiments, in which the inner projection is formed by molding the wall of the connecting sleeve. A sharp-edged transition between the inner lateral surface and the inner protrusion can be achieved particularly easily if the inner protrusion is part of the connecting disk.
  • the connecting sleeve is made in two parts.
  • Each part of the connecting sleeve is firmly connected on the end face to a receiving surface of the connecting disk.
  • the connecting disk thus protrudes into the interior of the connecting sleeve and forms the inner projection there.
  • This embodiment has the further advantage that vertical scaffold elements inserted into the connecting sleeve are in direct contact with the horizontally running connecting disk. This ensures a good flow of force in the horizontal or diagonal direction through the scaffold node.
  • the connecting disk has an in particular circular recess and at least a partial area outside of this recess forms the inner projection.
  • a recess is advantageously provided in the middle of the connecting disk. This recess is used so that vertically extending scaffold elements can 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 scaffold node in connection with a scaffold spindle. The scaffold spindle can then be moved vertically through the recess in the connecting disk.
  • Load-bearing, vertically running scaffolding components or scaffolding elements such as a Vertical stem or stem shaft of a spindle nut stem have a larger diameter than the recess in the connecting disk and therefore cannot be moved through this recess.
  • the recess in the connecting disc is not intended for pushing through such scaffolding elements.
  • the vertically load-bearing scaffolding elements come into contact with the jump-like inner projection arranged around the recess and transmit vertical loads to the scaffold 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 disc is very easy to manufacture and influence, since the connecting disc is a flat component that can be easily machined by punching, laser cutting, drilling or the like.
  • This embodiment thus combines the advantages of a simple structure with, at the same time, inexpensive production.
  • the connecting sleeve is made in one piece and the inner projection is formed by an indentation which extends 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 abruptly over the inner circumferential surface of the connecting sleeve, is also realized by molding the wall of a one-piece connecting sleeve. For this purpose, a circumferential impression is produced in the connecting sleeve. This embossing then protrudes inwards and forms the inner projection, which also has a load-bearing surface.
  • an inner projection formed by molding the wall also has a non-continuous, abrupt transition from the inner lateral surface to the load-bearing surface.
  • Such an embossed, jump-like transition can be achieved by correspondingly sharp-edged embossing tools that are used for the molding of the wall.
  • This embodiment is of a simpler construction since it comprises a connecting sleeve made in one piece.
  • the circumferential embossing represents a massive deformation of the wall of the connecting sleeve, so that an appropriate device must be available for such an embossing.
  • 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 internal projection is formed by molding the wall of the connecting sleeve, the internal projection inside the connecting sleeve having a constant projection height in the longitudinal direction of the connecting sleeve or the internal projection proceeding continuously from the inner lateral surface of the connecting sleeve to the projection height rises and falls.
  • a further inner protrusion is provided which has no abrupt transition to the inner circumferential surface. This further inner projection is formed by molding the wall of the connecting sleeve.
  • a corresponding stamping tool is used to produce such a further internal projection, which produces an internal projection with a continuous transition to the inner lateral surface.
  • wall means the wall of the tubular connecting sleeve.
  • Such shaping can take place, for example, by embossing or stamping.
  • the further inner projection consists of a partial area of the connecting sleeve, which is given its shape by a shaping process.
  • a tube section made of a Meta II material is used as the basis for producing a connecting sleeve according to this embodiment, and the further inner projection is then used reshaped into the wall.
  • a connecting sleeve with such a further internal projection can thus be produced very easily from inexpensive base material.
  • the further inner projection runs along the entire length of the connecting sleeve and has a constant projection height.
  • the protrusion height is to be understood as the extent to which the point of the inner protrusion which extends furthest into the interior of the connecting sleeve projects beyond the inner circumferential surface. Both the abruptly protruding inner protrusion and the further inner protrusion have a protrusion height.
  • the further inner projection does not run along the entire overall length, but extends only over 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 circumferential surface, the protrusion height rises steadily to the largest protrusion height and on the other side of the protrusion height steadily decreases again to the inner circumferential surface.
  • the further inner projection of a scaffold node ensures that vertical scaffold elements inserted in the connecting sleeve are centered.
  • the provision of a plurality of further internal projections, which then cooperate in the centering, is particularly favorable for this centering.
  • One or more further internal projections can be arranged in a targeted manner at favorable locations inside the connecting sleeve in order to achieve the desired centering of the vertically extending scaffolding elements in the connecting sleeve.
  • the centering achieved ensures that two vertically extending scaffolding elements, one of which is inserted from each side into the scaffolding node, are aligned with each other, thus enabling good and efficient power 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 Connection 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 leads into the connecting sleeve, vertically extending scaffolding elements along the entire length of the connecting sleeve.
  • the provision of three or more such further internal projections is particularly advantageous, since the centering effect on the scaffold elements introduced is again significantly improved by a larger number of further internal projections.
  • 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 further inner projections in the circumferential direction inside the connecting sleeve is particularly favorable for good centering of the scaffold elements introduced in the scaffold node.
  • 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 construction of a scaffold node is achieved in the described embodiment 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 circumferential surface, rises continuously 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 created by embossing with a pointed embossing tool. This creates a stamping point executed further internal projection inside the connecting sleeve. This reshaping process creates a constant transition between the inner surface and the further inner protrusion 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 protrusion height drops steadily to the inner surface. Due to these smooth transitions, such a further inner projection is particularly well suited for guiding a scaffold element, such as a vertical handle, inserted into the connecting sleeve. Starting from the inner lateral surface, the scaffold element glides smoothly over the further inner projection and is thus centered when it is inserted into the connecting sleeve.
  • the production of a further inner protrusion designed as an embossing point is also particularly simple since, starting from a tubular connecting sleeve, only a simple embossing tool is required for producing the further inner protrusion. No other components are required.
  • a plurality of 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 and the further internal projections along the rings in the circumferential direction are evenly distributed on the inner surface.
  • a plurality of further internal projections are provided which together guide and center a scaffold element introduced 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 constructive elements, but merely imaginary auxiliary lines to describe the arrangement of the further inner projections.
  • the further inner projections are arranged opposite one another in the interior of the connecting sleeve.
  • the maximum projection heights of the further inner projections define a clear width in the interior of 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 thus reduce the clear width inside the connecting sleeve.
  • the connecting sleeve is also advantageously 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 protrusion protruding abruptly over the inner circumferential surface of the connecting sleeve and at least one further inner protrusion which does not protrude suddenly, have particular advantages.
  • Vertically extending loads are first introduced directly into the scaffold node via the abruptly protruding inner projection from a vertically extending scaffold element which is inserted into the scaffold node. These loads are then transferred from the scaffold node to another, vertically extending scaffold element via the abruptly protruding inner projection.
  • An appropriately selected projection height of the abruptly protruding inner projection ensures that the loads of vertically extending scaffolding elements in any tolerance position of the external dimensions of these scaffolding elements are safely transmitted to and from the abrupt internal projection.
  • Another, not suddenly, in particular not sharp-edged inner projection helps center the vertically extending scaffold elements inserted in the scaffold nodes.
  • several further internal projections are advantageously provided, which center the vertically extending scaffold elements in the horizontal direction when inserted and also in the inserted state in the scaffold node. This centering has the effect that the front ends of the vertically extending scaffolding elements are optimally aligned with the abruptly projecting inner projection. This in turn creates a safe and stable flow of force between the inserted scaffold elements and the scaffold node.
  • the at least one further, non-abruptly projecting inner projection also transfers horizontally extending loads from the scaffold node to one or more vertically extending scaffold elements. Horizontal loads can be introduced into the scaffold node via the coupling element.
  • these horizontally running loads can or must also be transferred to the vertically running scaffolding elements. This is done in particular by the further internal projections which do not protrude abruptly. This further internal projection is in direct contact with a vertically extending scaffold element inserted in the scaffold node. Through this contact, horizontally running loads are transferred from the scaffold node to an inserted vertical style, for example, and vice versa.
  • the abruptly protruding inner projection serves in particular when assembling the scaffold or scaffold section also as an assembly stop when inserting scaffold elements or scaffold components in the longitudinal direction of the connecting sleeve. During assembly, these scaffolding elements or scaffolding components are simply inserted into the connecting sleeve until their end faces abut the abruptly protruding inner projection.
