Definitions
- the invention relates to a connection rosette for scaffold posts, such as those used in system scaffolds as nodes for coupling further system components, and to a scaffold assembly.
- Scaffolding is used in the construction sector as a working platform, for fastening concrete formwork or as a protective device.
- System scaffolds which include the so-called frame and module scaffolds, are made up of scaffolding components from a scaffolding system - usually a manufacturer-specific one.
- the system scaffolds have scaffold posts to be arranged vertically (vertically), which are provided with numerous connection or node points at which other system scaffold components, for example horizontal bars, diagonals and (Scaffold) brackets, attached and the scaffold posts can be connected to each other.
- the nodes are usually formed by a perforated disc called a connection rosette.
- the connection rosettes mostly consist of metal and are welded to the scaffold arm or attached in some other way.
- the cumulative mass of the connecting rosettes of a scaffold stem is a considerable disadvantage from the point of view of cost during manufacture and transport and also with regard to the manageability of the scaffold stems.
- connection rosette which can be manufactured overall using less material and at lower cost.
- a scaffolding assembly with a scaffolding assembly is to be specified.
- connection rosette with the features specified in claim 1.
- the scaffolding assembly according to the invention is specified in claim 11. Preferred developments of the invention are the subject of the description and the subclaims.
- the perforated disc or connection rosette according to the invention is provided for mounting on a scaffold post and is used to connect at least one further (system) scaffold component, for example a horizontal bolt, a so-called diagonal, in particular vertical diagonal, a console or other manufacturer-specific scaffold components.
- system further scaffold component
- connection rosette The passage recesses of the connection rosette enable the coupling parts of scaffold components to be detachably connected to the connection rosette, which are arranged at a distance from one another in the circumferential direction of the connection rosette.
- the connection rosette has an upper and a lower side surface, which are plane-parallel.
- the connection rosette is provided with a plurality of hollow embossings with (hollow embossing) elevations formed on only one of the two side surfaces and corresponding (hollow embossing) depressions in the respective other side surface.
- the hollow embossments are each arranged on a radial segment of the connection rosette, which extends in the radial direction from the inner edge to the Extends the outer edge of the connection rosette and through which one of the through recesses is delimited on both sides, and the hollow embossments are arranged at a distance from the through recesses. Due to the hole embossing, the connection rosette only has a functional thickness at defined points, which is greater than the nominal thickness of the connection rosette, ie the disk thickness of the connection rosette. As a result, the connection rosette can be made thinner overall, ie with a smaller nominal thickness, than was previously possible, while the load-bearing capacity remains sufficient.
- connection rosette offers manufacturing advantages as well as cost advantages. Due to the local functional thickening or increase in height of the connection rosette achieved with the hollow embossings, a defined support surface can be realized for a scaffold component to be connected to the connection rosette. This ensures a secure and play-free or essentially play-free fit of the scaffold component on the connection rosette. On the other hand, this can reliably counteract an undesirable incorrect or local overloading of the connection rosette.
- connection rosette existing scaffolding components that are designed for attachment to connection rosettes with a larger uniform nominal thickness can be easily connected to the connection rosette according to the invention without these having excessive play or being able to tilt.
- the nominal material thickness is the uniform material thickness of the connection rosette, which the connection rosette has in the areas without hollow stamping.
- connection rosette Due to the plane-parallel upper and lower side surfaces, the connection rosette can be cut or punched out inexpensively from a blank plate. All hollow embossings can be introduced into the material of the connection rosette at any time or as part of a follow-up composite process without any significant technical effort. As a result, the connection rosette can be provided inexpensively in mass production.
- the hollow embossings are all spaced apart from the passage recesses and are each arranged on a radial segment of the connection rosette, which extends in the radial direction from the The inner edge extends to the outer edge of the connection rosette and through which one of the opening recesses is delimited on both sides.
- each of the aforementioned rosette segments has only one hollow embossing. On the one hand, this can avoid excessive structural weakening of the connection rosette.
- the elevations of the connection rosette defined by the hollow embossments serve as support surfaces for the scaffolding components to be connected to the connection rosette.
- the elevations preferably have a rounded shape rather than a sharp-edged shape. This can reliably counteract undesired tilting of the scaffolding components to be connected or decoupled from the connection rosette. This is also advantageous from an occupational safety point of view.
- all hollow embossments are arranged uniformly spaced from the central axis of the connection rosette. As a result, an advantageous axially symmetrical loading of the connection rosette can be achieved at the support points formed by the elevations.
- the elevations can all agree with one another in terms of their shape and / or their dimensions. On the one hand, this offers manufacturing advantages. On the other hand, handling errors can be avoided.
- All elevations of the hollow embossments particularly preferably have a circular cross-sectional shape.
- This cross-sectional shape enables a special load-stable execution of the surveys and at the same time only a small one
- the elevations preferably have a height h which corresponds to a maximum of half the nominal thickness DN of the connection rosette.
- the functional thickness of the connection rosette can be increased to at least 1.5 times the nominal thickness of the connection rosette.
- connection rosette can in principle have a uniform shape and size or, at least in part, differ from one another in terms of their shape and size for the possible connection of different scaffolding components. So the connection rosette can be first and second
- the first passage recesses are especially for the connection of
- the smaller second passage recesses are particularly suitable for coupling diagonals, for example vertical diagonals.
- the second passage recesses can in particular have a circular shape.
- the scaffold assembly according to the invention comprises a scaffold arm with a connection rosette explained above and a scaffold component which is detachably attached or coupled to the connection rosette.
- the scaffold component has either one or more positioning pins, wherein according to a first alternative embodiment each positioning pin engages in a recess in a hollow embossing of the connection rosette.
- the scaffold component in its state mounted on the connection rosette
- Such a rotating or swiveling stop can be used to pry the lever off into one of the through recesses or via one of the recesses Passage recesses unplugged connection head of the scaffold component can be avoided from the scaffold component. This is advantageous for the longevity of the scaffolding component and the connection rosette.
- the scaffold component can be designed as a diagonal, preferably a vertical diagonal, which has a fork head at one end with a receiving gap for connection rosettes with a nominal thickness that is greater than the nominal thickness of the connection rosette, and which, in its detachably mounted state on the connection rosette, has the connection rosette on both sides in overlaps in the axial direction and is secured to the connection rosette by means of a locking or securing element which passes through one of the through recesses of the connection rosette.
- the scaffold component can alternatively be a horizontal bar which has a coupling hook at one end, which engages in one of the passage recesses of the connection rosette.
- a safety wedge or the like can be assigned to the coupling hook.
- each positioning pin of the locking head can be dimensioned in length in such a way that it can transmit normal forces from the horizontal locking bar to the connection rosette. In other words, each positioning pin of the locking head can be made longer than the recess of the corresponding hollow embossing of the connection rosette is deep.

- the first passage recesses 16 are larger than the second passage recesses 18 and are each open to the central recess 14 of the connection rosette 10.
- the first passage recesses 16 serve primarily for the detachable connection of scaffolding components in the form of horizontal bars.
- Such scaffolding components generally have coupling parts in the form of hooks, in particular with a safety wedge, which can be hooked into the first passage recesses 16.
- the second passage recesses 18 are each circular here and serve to connect scaffolding components in the form of diagonals, in particular so-called vertical diagonals.
- a radially inward-facing indentation 20 of the outer edge 22 of the connection rosette 10 can be assigned to the second passage recesses 18.
- These scaffolding components are generally secured or unplugged to the connection rosette 10 using a securing bolt.
- connection rosette 10 has a small nominal thickness, so that it can be provided with less material and with a reduced mass.
- Existing scaffolding components from manufacturer-specific scaffolding systems available on the market are designed for connection to connection rosettes with a significantly larger nominal thickness in comparison.
- the connection rosette 10 is compatible with such scaffold components, ie, regardless of its smaller nominal thickness, such scaffold components allow an essentially play-free fit on the connection rosette 10.
- the connection rosette 10 is provided with several individual hollow embossments 24.
- the hollow embossments 24 have elevations 26, all of which are formed on only one of the two side surfaces 12 of the connection rosette 10 (FIGS. 3 and 4).

- hollow embossments are no longer required functionally. 1, all the hollow embossments 24 of the connection rosette 10 are arranged at a uniform distance from the central axis Z of the connection rosette 10. The hollow embossments 24 are thus all arranged on a circular line 34 around the central axis Z of the connection rosette 10.
- the second passage recesses 18 are arranged completely in the radial direction within the circular line 34.
- the elevations 26 of all the hollow embossments 24 have a circular cross-sectional shape. Due to the all-round connection of the elevations to the remaining connection rosette, these are reliably secured against unwanted shearing off or tearing off.
- connection rosette 10 clearly visible.
- the two side surfaces 12a, 12b define the nominal thickness DN of the connection rosette 10, which in each case is less than 7.1 millimeters, in particular approximately 6 millimeters.

- connection rosette shown in FIG. 6 two diagonals can be connected in order to couple a scaffold post provided with the connection rosette 10 to another scaffold post or to mechanically attach it to a building wall or the like.
- a scaffold assembly 100 is shown with a diagonal connection.
- the scaffold assembly comprises a scaffold arm 40 with a connection rosette 10 according to FIG. 1 and with only one part shown schematically with dashed line scaffold component 42 which is releasably attached to the connection rosette 10.
- the scaffold post 40 is designed in a manner known per se as a hollow profile and has a circular cross-sectional shape. It is understood that the scaffold post 40 can also have a different cross-sectional shape.

- the side surface 12a of the connection rosette 10 provided with the depressions 28 of the hollow embossments 24 faces upward (in the perpendicular direction), while the side surface 12b of the connection rosette 10 provided with the elevations 26 points downwards. This simplifies the assembly of scaffolding components on and the dismantling of scaffolding components from the connection rosette 10.
- the load on the elevations 26 of the hollow embossments 24 is significantly smaller in this assembly than if they were to point vertically upward from the connecting rosette 10.
- the scaffold component 42 is designed as a vertical diagonal with a hollow profile 44 and a fork head 46 fastened to the hollow profile 44.
- the fork head 46 is arranged in its predetermined mounting position on the connection rosette 10 of the scaffold stem 40.
