Definitions

  • the invention relates to a length compensation element for a scaffolding component, in particular for a horizontal bar or a traverse, and a scaffolding component with such a length compensation element.
  • the invention also relates to a scaffold and the use of a length compensation element in a scaffold.
  • Modular scaffolding includes prefabricated, standardized scaffolding components that can be assembled to form complex planar or spatial scaffolding. These are in particular vertical standards, horizontal bars, diagonal struts and scaffold nodes. The latter serve to connect the scaffolding components to one another. Decks, which are also standardized, are attached to form walkable scaffolding levels.
  • scaffolding systems can be used. For example, there are scaffolds for light, medium or heavy loads. The higher the load requirements, the greater the pipe diameter and/or the wall thickness of the vertical standards. This leads to the problem that vertical standards from different systems cannot be combined, or can only be combined with great difficulty, since the clearances between the vertical standards change and the further standardized scaffolding components matched to the system, in particular Horizontal ledgers and decks can no longer be used. Scaffolding components can therefore usually not be used across systems. This means that a large number of scaffolding components must be kept available for each system. This leads to high acquisition and storage costs.
  • the object of the invention is therefore to increase the compatibility of standardized scaffolding components with one another. In this way, the number of parts should be reduced and costs saved.
  • the length compensation element with the features of claim 1 the scaffolding component with the features of claim 7 and the scaffolding with the features of claim 10 are proposed.
  • Advantageous developments of the invention can be found in the respective dependent claims.
  • the use of a length compensation element according to the invention in a framework is proposed.
  • the length compensation element proposed for a scaffolding component in particular for a horizontal bar or a traverse, has a tubular profile, in particular rectangular tube, which is connected to the scaffolding component via first connecting means arranged at the end and to a further scaffolding component arranged perpendicularly in relation to the scaffolding component via second connecting means arranged at the end is connectable.
  • the first connecting means comprise a connecting element running perpendicular to a longitudinal axis of the first tube profile and a connecting element arranged thereon with a receiving opening.
  • the proposed length compensation element enables the integration of non-system scaffolding components, in particular vertical standards, into a scaffolding system with standardized scaffolding components. If the clear dimensions between the vertical standards change, length compensation can be achieved with the help of the length compensation element, so that system-specific scaffolding components, in particular horizontal ledgers and/or decking, can still be used. A length adjustment of the scaffolding component is not necessary, since the missing length is compensated by the length compensation element.
  • a horizontal ledger and/or decking can be added - within the system next lower level can be selected. This means that the horizontal bar and/or covering is shorter, so that the required length compensation can be effected with the aid of the proposed length compensation element.
  • the length of standardized scaffolding components can vary within a scaffolding system.
  • Horizontal ledgers and decks of different lengths are often kept in stock, whereby the lengths - based on a basic grid - gradually increase. In this way, scaffolding bays of different sizes can be realized without having to change the system.
  • the proposed length compensation element enables the use of non-system vertical standards in a scaffolding with standardized scaffolding components.
  • the compatibility of the scaffolding components with each other increases accordingly, especially those that belong to different systems.
  • the ledgers and/or decks can be used across systems, so that the number of parts is reduced. Furthermore, the acquisition and storage costs are reduced. Only the proposed length compensation elements must also be kept available.
  • the proposed length compensation element preferably serves to extend a horizontal bar or a traverse within a scaffolding, it preferably has a rectangular tube as a tubular profile, analogously to the horizontal bar or traverse. Furthermore, the rectangular tube of the length compensation element preferably has the same cross section as the rectangular tube of the horizontal heg eis and/or the traverse. The length compensation element can then be arranged in line with the horizontal ledger or the traverse, so that there is no height offset. Since the decks are usually hooked in so that they come to rest on a horizontal bar or a traverse at the end, this ensures that all decks are on one level.
  • the tube profile, in particular rectangular tube, of the length compensation element has at both ends connecting means for connection to a first scaffolding component to be lengthened, preferably a horizontal bar or a traverse, and to a second scaffolding component.
  • the second scaffolding component can in particular be a vertical post with a rosette-like connecting element, into which the first scaffolding component, preferably the horizontal bar, would have been suspended if the was the right length. If the first scaffolding component to be lengthened is a traverse, the second scaffolding component can also be a horizontal bar, into which the traverse would have been hung if it had had the correct length.
  • the first and second connecting means of the length compensation element arranged on the tube profile, in particular on the rectangular tube, are preferably designed in such a way that they each enable a detachable connection of the length compensation element to a scaffolding component.
  • the length compensation element - like the other scaffolding components - can be easily dismantled and reused.
  • first connecting means are provided at a first end of the tube profile, in particular a rectangular tube. These include a connecting element running perpendicularly to a longitudinal axis of the tube profile and a connecting element arranged thereon with a receiving opening. Connecting means arranged at the end on the first scaffolding component can be inserted into the receiving opening and can in particular have a wedge and/or locking element.
  • a horizontal bar is usually connected to a vertical post with the aid of such connecting means.
  • the connecting means of the horizontal bar are inserted into a receiving opening of a rosette-like connecting element connected to the vertical post.
  • the receiving opening of the connecting element of the first connecting means of the length compensation element is preferably designed in the same way as the receiving opening of a rosette-like connecting element of a vertical post, so that the detachable connection between the length compensation element and the horizontal bar can be implemented in the same way as the usual detachable connection of the horizontal bar to a vertical post.
  • the connecting element of the first connecting means has a connecting surface that is at least partially convex.
  • the convex connection surface corresponds to a concave end face of the scaffolding component to be lengthened, so that a form fit results, via which the component to be lengthened is optimally supported.
  • the scaffolding component to be extended is, for example, a horizontal bar, which is usually connected to a vertical standard, this can have a concave contour at the end in a plan view, which is adapted to the outer diameter of the vertical standard.
  • the horizontal ledger When connected to the vertical standard, the horizontal ledger then lies against the vertical standard on the outer circumference, so that it is optimally supported.
  • connection/support can also be achieved between a horizontal bar and the connection element of the first connection means of the length compensation element if the convex connection surface has the radius of a vertical post.
  • the convex connection surface of the connection element imitates a vertical post.
  • the connecting element of the first connecting means is therefore aligned vertically, analogously to a vertical post, when the proposed length-compensating element is installed in a scaffold.
  • the tubular profile is aligned horizontally - analogous to a horizontal ledger. While the tube profile - analogous to a horizontal bar - is preferably designed as a rectangular tube, the connection element - analogous to a vertical post - can in particular be a round tube. In this case, the connecting element is arranged in an outer peripheral area of the round tube.
  • the connecting element can be a head plate that is convex at least in some areas and is placed in front of the tube profile on the face side, so that a form fit with the scaffolding component to be extended, in particular horizontal bars, can be produced.
  • the connecting element of the first connecting means of the length compensation element be designed in the shape of a disk and be aligned perpendicularly to a longitudinal axis of the connecting element.
  • the connecting element imitates a rosette-like connecting element of a vertical post.
  • the connecting element only has to have one receiving opening, since only one scaffolding component, in particular a horizontal rail or a traverse, has to be connected to the length compensation element via the first connecting means. If the scaffolding component to be extended is a horizontal ledger, the connection with the length compensation element can be made in the same way as with a vertical standard. This means that no changes need to be made to the ledger to be extended.
  • the connecting element of the first connecting means of the length compensation element forms a console with a bearing surface pointing upwards in the installed position, so that the scaffolding component to be extended, in particular a lengthening ledger or a traverse to be lengthened, can be stored.
  • the bracket carries the scaffolding component to be extended in the installation position.
  • the scaffolding component to be lengthened is also securely held in the installed position by connecting means which are inserted into the receiving opening of the connecting element of the first connecting means of the length compensation element.
  • the bearing surface of the connecting element forming the bracket is aligned with a lower side surface of the tube profile of the length compensation element, which is preferably designed as a rectangular tube. If the length compensation element and the scaffolding component to be extended have the same cross-section, this measure ensures that they are aligned in the installation position. In this way, height offsets are avoided and the decks can still be installed lying on one level.
  • the second connecting means of the length compensation element are preferably designed analogously to the connecting means of the scaffolding component to be lengthened, preferably analogously to the connecting means of a horizontal bar or a traverse.
  • the length compensation element preferably also has connecting means that include a wedge and/or locking element. This is or these can then be used to connect the length compensation element to a vertical post as a further scaffolding component in a receiving opening of a rosette-like connecting element of the vertical post.
  • the length compensation element has modified second connection means. Because a traverse is usually not connected to a vertical standard, but to two other ledgers. A traverse therefore usually has an L-shaped or U-shaped bracket at each of its two ends for hanging between two horizontal bars.
  • the second connecting means of the length compensation element preferably comprise an L-shaped or U-shaped angle with a bearing surface pointing downwards in the installed position.
  • the traverse which has been lengthened at least on one side with the aid of the length compensation element, can then be placed on a horizontal bar be launched.
  • the traverse can be secured against displacement in the direction of its longitudinal axis via a further surface of the bracket arranged perpendicularly to the support surface.
  • the bracket In the installed position, the bracket therefore has at least one horizontal and one vertical leg.
  • the bracket preferably has a second horizontal leg (U-shaped bracket).
  • the bracket can then be connected to a horizontal bar in such a way that it encompasses the horizontal bar on three sides. Furthermore, the support surface of the bracket, which faces downwards in the installed position, is preferably aligned with an upper side surface of the tubular profile or rectangular tube. In this way, the traverse can be installed at the same height as the ledger on which the angle of the length compensation element rests. The coverings can thus be arranged lying in one plane.
  • the length of a scaffold bay can be shortened or lengthened, for example in order to use decking across systems.
  • the traverse is installed at a distance parallel to a first horizontal bar and installed between two further horizontal bars running transversely to the first horizontal bar.
  • the decks then only have to span the distance between the traverse and a fourth horizontal ledger or between two parallel traverses.
  • the truss thus represents a special component that increases the compatibility of the scaffolding components with one another.
  • a traverse as a special component can be dispensed with.
  • a ledger is used in combination with at least one length compensation element.
  • the extended horizontal ledger then serves as a traverse. This reduces acquisition and storage costs.
  • this is preferably a horizontal ledger in the function as a traverse.
  • a scaffolding component is also proposed, in particular a horizontal bar or a traverse, the scaffolding component being detachably connected at least at one end to a length compensation element according to the invention for the purpose of lengthening. Due to the detachable connection, the length compensation element can be connected to a large number of scaffolding components that it can be used when needed. Such a need can exist in particular when non-system vertical standards are used in scaffolding, for example to increase its load-bearing capacity.
  • the length compensation element has modified second connection means. This means that there are at least two types of length compensation elements and thus two types of scaffolding components, in order to take account of the different installation positions.
  • a horizontal ledger lengthened with the aid of the length compensation element according to the invention is used as a traverse
  • a special component “traverse” can be dispensed with.
  • the horizontal bar serving as a traverse is then connected at both of its ends to a length compensation element according to the invention. In this way it can be ensured that the extended horizontal bar can be connected at both ends to a transverse horizontal bar.
  • the proposed scaffolding component preferably has at least one side surface which is aligned with a side surface of the tube profile, in particular rectangular tube, of the longitudinal compensation element. If only one side surface of the scaffolding component is aligned with a side surface of the tubular profile or rectangular tube, this is preferably the upper side surface in the installed position. This ensures that there is no height offset and that the decks can be installed lying on one level. All side surfaces of the scaffolding component and those of the profile tube or rectangular tube are preferably in alignment. Because in this case the scaffolding component and the length compensation element can be manufactured from the same rectangular tube, so that the manufacturing costs are reduced.
  • the scaffolding component preferably has connecting means at at least one end, which are designed analogously to the second connecting means of the length compensation element. Accordingly, the type of connection of the scaffolding component to another scaffolding component does not change as a result of the extension.
  • the connecting means preferably each comprise a wedge and/or locking element.
  • the connecting means of the horizontal bar preferably differ from the second connecting means of the length compensation element. Because then the extended horizontal bar is not connected to a vertical standard at the end, but to another horizontal bar running transversely.

  • connecting means 22 which are arranged at the end of the crossbeam 20 and comprise a wedge element and a locking element, are inserted into the receiving opening 213 of the connecting element 212 . Since the traverse 20 is formed here by a horizontal bar 10, the connecting means 22 are similar to the connecting means 12 of a horizontal bar 10.
  • a conventional traverse 20' is shown in FIGS. 9 and 10 as an example. It represents a special component that allows the use of the same coverings 50 with changed dimensions of the framework 1.
  • the traverse 20' is suspended at a distance parallel to a horizontal bar 10 between two horizontal bars 40 running transversely thereto (see FIG. 10).
  • the traverse 20' has a U-shaped angle at each of its two ends as a connecting means 22' (see FIG. 9).
  • the length compensation element 200 according to the invention shown in FIG. 6 makes it possible to dispense with a traverse 20', since instead of this a horizontal bar is used, which is extended on both sides with a length compensation element 200.
  • these scaffolding components then form a traverse 20 .
  • the length compensation elements 200 arranged at both ends of the horizontal heg ice have second connecting means 220 in the form of a U-shaped angle. The traverse 20 can thus be hung between two parallel horizontal bars 40 in the same way as the traverse 20' shown in FIG.
  • the U-shaped angle forms a support surface 221, which is arranged flush with the upper side surface 203 of the tubular profile 201 of the length compensation element 200, so that the upper side surface 203 of the tubular profile 201 comes to rest at the same height as the upper side surfaces 11 , 41 of the horizontal bars 10, 40. Since the contact surface 214 of the connecting element 212 of the length compensation element 200 is also aligned with the lower side surface 202 of the tubular profile 201 and the tubular profile 201 has the same cross-section as the horizontal bar forming the traverse 20, the upper side surface 21 of the Traverse 20 also to be at the same height. This means that the coverings 50 suspended between two traverses 20 are all arranged in one plane.
  • FIG. 6 differs from that of FIG. 1 essentially only in that it has modified second connecting means 220. These allow a horizontal bar 10 to be installed in a different position, so that it can be used as a traverse 20 .
  • the first connecting means 210 can be designed identically to those of the length compensation element 100 in FIG .
  • the first connecting means 110, 210 of both embodiments can each have a convex head plate instead of a round tube as the connecting element 11, 211 (not shown).
