Definitions
- the invention relates to a scaffolding node, a scaffolding rosette, a scaffolding handle and a scaffolding bar.
- the invention also relates to a manufacturing method for a scaffolding rosette.
- Scaffolds are used, for example, as shoring for supporting loads and as working scaffolding, in particular as facade scaffolding, with working levels for workers.
- two scaffolding standards of a scaffolding are releasably connected to one another by a scaffolding bolt.
- the connection between the scaffold standard and the scaffold ledger is known as a scaffold node.
- the scaffolding posts can each have a scaffolding rosette, into which the scaffolding bolt engages with a plug-in pin.
- Such scaffolding rosettes are usually designed as stamped parts and welded to a scaffolding tube of the scaffolding post. For sufficient stability, however, such punched rosettes must have a great thickness of typically at least 6 mm.
- a scaffolding node according to claim 1 a scaffolding rosette according to claim 3, a scaffolding post according to claim 8, a scaffolding bar according to claim 10 and a method according to claim 17.
- the respective subclaims indicate advantageous embodiments.
- the scaffolding node according to the invention has a scaffolding post with a scaffolding tube and a scaffolding rosette.
- the scaffolding tube typically extends in the vertical direction in the assembled state of the scaffolding node. At least one receiving recess is formed in the scaffolding rosette.
- the scaffolding node furthermore has a scaffolding bolt with a locking section, an insertion pin for insertion into the receiving recess of the scaffolding rosette and a securing element.
- the locking section In the assembled state of the scaffolding node, the locking section typically extends in a horizontal direction.
- the bolt section in the assembled state preferably runs perpendicular to the scaffold tube.
- the locking section is typically arranged above the scaffolding rosette and preferably rests directly on it.
- the insertion pin typically protrudes essentially perpendicularly from the locking section.
- the plug-in pin protrudes through the scaffolding rosette, preferably from top to bottom.
- the securing element is used to secure the scaffold bar on the scaffold handle, so that the scaffold bar cannot inadvertently detach from the scaffold handle.
- the securing element is rotatably held on the locking section.
- the securing element can typically be rotated horizontally.
- the securing element can in particular be rotatable about a vertically extending axis of rotation with respect to the locking section.
- the fuse element is in a
- the securing element can be rotated for this purpose.
- the securing element engages under the scaffolding rosette when the plug-in pin is inserted into the receiving recess, ie when the scaffolding bolt is in the mounted state on the scaffolding handle.
- the securing element and the locking section are arranged on opposite sides of the scaffolding rosette.
- the release position the securing element does not reach under the scaffolding rosette.
- the scaffolding bar can therefore be detached from the scaffolding handle or attached to it.
- On the basis of the rotational position of the securing element it can be easily recognized whether the securing element is in the securing position or the release position. This helps to avoid operating errors.
- the scaffolding post is preferably a scaffolding post according to the invention described below with a scaffolding rosette according to the invention described below.
- the scaffold bar is preferably a scaffold bar according to the invention described below.
- the securing element can be braced in the securing position with the scaffolding rosette and the locking section.
- the components are in contact with one another without play. This can further increase the stability of the scaffold node.
- the bracing prevents the securing element from being inadvertently transferred into the release position.
- a scaffolding rosette also falls within the scope of the present invention.
- the scaffolding rosette is intended in particular for a scaffolding node according to the invention described above.
- the frame rosette is designed in the form of a bent sheet metal part.
- the bent sheet metal part of the scaffolding rosette has a main section extending in a main plane. In other words, the main section is flat. In the main section
- the framework rosette has at least one stiffening section angled relative to the main section.
- the stiffening section increases the stability of the scaffolding rosette.
- the main section and the stiffening section are basically formed in one piece with one another. In the context of the present invention, in particular those components are referred to as one-piece, the material connection of which was obtained by primary molding, but not by joining.
- the framework rosette preferably has a plurality of angled stiffening sections. Typically the plurality of stiffening sections are angled in the same direction away from the main section.
- the scaffolding rosette is advantageously rotationally symmetrical about an imaginary axis of symmetry running perpendicular to the main section, in particular with respect to rotations by multiples of 90. Since the scaffolding rosette is designed as a bent sheet metal part, it can be produced efficiently and inexpensively. As a result of the stiffening section or the stiffening sections, a thickness of the sheet metal can be reduced compared to a conventional scaffolding rosette made from flat sheet metal.
- the scaffolding rosette according to the invention can have a sheet thickness of approximately 3 mm.
- the sheet metal thickness of the framework rosette according to the invention is preferably at least 2.0 mm, particularly preferably at least 2.5 mm.
- the sheet metal thickness of the framework rosette according to the invention is preferably at most 4.0 mm, particularly preferably at most 3.5 mm.
- the sheet metal thickness is advantageously the same for the main gate and the at least one stiffening section.
- the scaffolding rosette stiffened according to the invention can be made significantly lighter, often over 30% lighter, with similar stability.
- the at least one stiffening section preferably extends essentially at right angles to the main section. This gives the scaffolding rosette a particularly high level of stability, in particular rigidity and resilience. Essentially right-angled means in particular that an angle between the main section and the stiffening section is at most 20 °,
- Peri GmbH preferably at most 15 °, very particularly preferably at most 10 °, extremely preferably at most 5 °, deviates from a right angle (90 °).
- the framework rosette advantageously has two stiffening sections which extend on the outside of the framework rosette. This further increases the stability of the scaffolding rosette.
- the reinforcing sections on the outside can also form an outer contour of the scaffolding rosette.
- the two stiffening sections can extend at an angle to one another, in particular run at right angles to one another in sections.
- the two externally extending stiffening sections end at a distance from one another in the corner area of the main section.
- the engagement area allows a securing element of a scaffolding bolt to be inserted between the reinforcing sections on the outside and to be brought into contact with the main section.
- the main section basically forms the outer contour of the scaffold rosette. Following this, the outer contour is typically also formed by the reinforcing sections on the outside.
- An advantageous scaffolding rosette is characterized in that the scaffolding rosette has an inner stiffening section on the receiving recess. This further increases the stability of the scaffolding rosette.
- the inner stiffening section surrounds the receiving recess at least in sections.
- a plurality of receiving recesses, each surrounded by an inner stiffening section, are preferably formed.
- the scaffolding post has a scaffolding tube.
- a scaffolding rosette according to the invention described above is attached, in particular welded, to the scaffolding tube.
- the scaffolding tube is preferably a round tube.
- the scaffolding tube can have a wall thickness of 2 mm, in particular at least 1.5 mm and at most 2.5 mm. Since the scaffold rosette according to the invention can be made comparatively thin due to the stiffening section, cf. above, i.e. in particular with a sheet metal thickness that does not differ significantly from the wall thickness of the scaffold tube, the scaffold tube and the scaffold rosette can be welded to one another without problems. This enables cost-effective production of high quality scaffolding standards. Due to the small wall thickness or small sheet metal thickness possible according to the invention, the scaffold post according to the invention is also very light.
- the receiving recess can be delimited in sections by the scaffolding tube.
- a scaffold bolt mounted on the scaffold post can then advantageously be supported on the scaffold tube in order to establish a rigid connection.
- the production of the scaffolding rosette can be simplified if the receiving recess is not completely delimited by the main section and possibly an inner stiffening section.
- a scaffold bar also falls within the scope of the present invention.
- the scaffold bar is provided in particular for a scaffold knot according to the invention described above.
- the scaffolding bolt has a bolt section and a plug-in pin.
- the insertion pin protrudes from the locking section.
- the insertion pin and the locking section can extend essentially perpendicular to one another.
- the scaffold bar continues to instruct
- the securing element is rotatably held on the locking section.
- the securing element In the assembled state of the scaffold bar, ie in particular the assembled state of a scaffold node with the scaffold bar, the securing element can typically be rotated horizontally. In the assembled state, the securing element can in particular be rotatable about a vertically running axis of rotation with respect to the locking section.
- the scaffolding bolt By means of the securing element, the scaffolding bolt can be secured against unintentional removal on a scaffolding rosette.
- the securing element can be brought (rotated) into a securing position.
- the securing element In order to mount or dismantle the scaffolding bolt, the securing element can be brought into a release position (rotated).
- the bolt section has a stop for the securing element.
- the stop makes it easier to operate the scaffold bar and helps to avoid mistakes when setting up a scaffold knot with the scaffold bar.
- the stop can define the securing position or prevent rotation of the securing element (starting from the release position) beyond the securing position.
- a support segment for the securing element is preferably formed on the locking section. When the securing element is in the securing position, the securing element can be supported on the support segment.
- the support segment is advantageously formed in one piece with the locking section.
- the locking section and the support segment can be designed as a bent sheet metal part. This simplifies production and increases the stability of the scaffold bar.
- the securing element can have a support section for supporting on the support segment and a securing section for engaging under a scaffold rosette.
- the securing element can be rotatably mounted between the support section and the securing section.
- the scaffold bolt preferably has a tensioning means for tensioning the securing element with the bolt section.
- the clamping means By means of the clamping means, the securing element can be brought to rest on the locking section and on a scaffolding rosette without play. As a result, the stability of a scaffold knot can be further increased with the scaffold ledger.

- the securing element can, in particular between the support section and the securing section, have a bore through which the securing means is guided.
- the locking section and the insertion pin are preferably formed in one piece with one another, in particular as a bent sheet metal part. This allows a cost-effective and efficient production. In addition, such a scaffold bar is very stable.
- a first and a second contact section for contact with a scaffolding tube can be formed on the insertion pin.
- a third contact section for contact with the scaffold tube can be formed on the locking section.
- the contact sections allow a precise alignment of the scaffolding bolt relative to the scaffolding tube.
- the third contact section is preferably far, in particular at least 5 cm, preferably at least 10 cm, away from the first and the second contact section. This increases the stiffness of the connection
- the first and the second contact section are advantageously formed close to a free end of the insertion pin.

- the scaffolding post 12 comprises a scaffolding tube 16 and a scaffolding rosette 18.
- the scaffolding rosette 18 is firmly connected to the scaffolding tube 16. Here the scaffolding tube 16 and the scaffolding rosette 18 are welded together.
- the scaffolding rosette 18 surrounds the scaffolding tube 16. In other words, the scaffolding tube 16 extends through the scaffolding rosette 18.
- the scaffold tube 16 is designed with an annular cross section.
- the scaffold bolt 14 has a bolt section 20 and an insertion pin 22.
- the locking section 20 extends perpendicular to the scaffolding tube 16 of the scaffolding handle 12.
- the insertion pin 22 protrudes from the locking section 20.
- the insertion pin 22 extends essentially perpendicular to the locking section 20.
- the insertion pin 22 runs essentially parallel to the scaffolding tube 16. It should be noted that the insertion pin 22 has a variable cross section in its direction of extension; the previously described course of the insertion pin is therefore to be understood qualitatively.
- the insertion pin 22 protrudes through a receiving recess 24 of the framework rosette 18.
- the framework rosette 18 has four receiving recesses 24 here. Each of the receiving recesses 24 is for receiving one
- the scaffolding post 12 can have a plurality of scaffolding rosettes 18, which can be fastened to the scaffolding tube 16 at a distance from one another (not shown).
- the scaffold bar 14 has a securing element 26.
- the securing element 26 In the figures la-ld the securing element 26 is in a securing position. In the securing position, the securing element 26 engages under the scaffolding rosette 18. In the securing position, the securing element 26 prevents the scaffolding bolt 14 from being released from the scaffolding handle 12.
- the securing element 26 is rotatably held on the scaffold bar 14.
- a screw 28 protrudes through the securing element 26.
- the screw 28 is supported on the one hand on the securing element 30, here with a screw head 30, cf. FIG. 2.
- the screw 28 is supported on the scaffolding bolt 14.
- the screw 28 engages in a nut 32 which rests on a support segment 34 of the locking section 20.
- the nut 32 can be permanently connected to the support segment 34, in particular pressed or welded. Instead of the nut 32, a thread for engaging the screw 28 could be formed in the support segment 34 (not shown).
- the screw 28 serves as a tensioning means 36 in order to brace the securing element 26 with the framework rosette 18 and the locking section 20, here the support segment 34 of the locking section 20.
- the scaffolding bar 14 can be connected to the scaffolding post 12 without play. A greater rigidity of the scaffold node 10 can thereby be obtained.
- the securing element 26 is shown in FIGS. 6a, 6b and 6c.
- the securing element has a support section 38 for resting on the support segment 34 of the scaffolding bolt 14 and a securing section 40 for reaching under the scaffolding rosette 18. Between the support section 38 and the securing section 40 there is a bore 42 for passing through the clamping means
- the screw 28 is provided in the securing element 26.
- the screw 28 and the bore 42 define an axis of rotation 44 for the securing element 26, see also FIG. 2.
- the securing element 26 is cranked, cf. Figures 6a-6c.
- the support section 38 is offset in relation to the securing section 40 and the bore 42 in the direction of the axis of rotation 44.
- FIGS. 3a, 3b and 3c the scaffolding node 10 is shown, the securing element 26 being in a release position.
- the securing element 26 has been rotated about the axis of rotation 44 so that it does not reach under the scaffolding rosette 18.
- the securing section 38 of the securing element 26 is arranged next to the scaffolding rosette 18 in the release position - when viewed from below, cf. in particular Figure 3b.
- the scaffolding bolt 14 can be released from the scaffolding handle 12 or mounted on it.
- FIGS. 4a, 4b, 4c and 4d show a first end area of the scaffolding bolt 14 in different views.
- a second end region of the scaffold bar 14 is shown.
- the first and the second end areas of the scaffold bar 14 are designed in the same way.
- the two end areas are identical when viewed from the center of the scaffold bar. This also applies accordingly when the two end areas are viewed from outside.
- a plug-in pin 22 is formed in each of the end regions.
- a securing element 26 is arranged on the locking section 20 in each of the end regions.
- FIG. 5 shows the first end area of the scaffold bar 14 in a partial section. It can be seen in particular that the securing element 26 is rotatably supported and held on the support segment 34 of the locking section 20 by means of the tensioning means 36 (screw 28). A stop 46 for the securing element 26 is set up on the scaffold bar 14. The stop 46 is in the first end area, cf. FIGS. 4a-4d, of a first side wall 48a of the scaffolding bolt 14 or in the second end area, cf. Figure 4e, from a second
- Side wall 48b of the scaffolding latch 14 is formed.
- the support segment 34 is in each case formed by bending over a region of that side wall 48b or 48a which side wall 48b, 48a does not form the stop 46 for the respective securing element 26.
- the stops 46 prevent the securing element 26 from rotating beyond the securing position with respect to a first direction of rotation.
- the stops 46 are each designed such that when the screw 28, which has a right-hand thread, is tightened, the securing elements 26 are guided against the stops 46 by the rotation of the screw 28. In other words, when the screws 28 are tightened clockwise, the securing elements 26 are entrained due to friction, so that the angled support sections 38 come to rest against the stops 46. This simplifies the assembly of the scaffolding bolt 14.
- tensioning the securing element 26 by tightening the tensioning means 36 (screw 28) the securing element 26 is first automatically transferred into the securing position, then the securing element 26 is clamped between the screw head 30 (see FIG.
- the locking section 20 with the support segments 34 and the plug-in pins 22 are designed here in one piece with one another as a bent sheet metal part, cf. also Figures 4a-4e.

- Figures 7a, 7b and 7c show the scaffolding rosette 18 of the scaffolding post 12 in different views.
- the frame rosette 18 has four receiving recesses 24 for insertion pins 22.
- the receiving recesses 24 are in each case in sections from the scaffolding rosette 18 itself and in sections from the scaffolding tube 16 of the
- the scaffolding rosette 18 also has a central passage 58 for passing a scaffolding tube 16 through.
- the scaffolding rosette 18 also has four through recesses 60 here, which are completely delimited by the scaffolding rosette 18.
- the through recesses 60 are each arranged between two of the receiving recesses 24.
- the frame rosette 18 is designed as a one-piece bent sheet metal part.
- the framework rosette 18 has a flat main section 62.
- the main section 62 extends in a main plane of the framework rosette 18. In other words, the main section 62 is flat.
- the scaffolding rosette 18 also has several stiffening sections 64, 66. The stiffening sections 64, 66 are angled with respect to the main section 62 and protrude from this at right angles here.
- the stiffening sections 64 are formed on the outside of the framework rosette 18. Here four outer stiffening sections 64 extend along outer edges of the scaffolding rosette 18. The outer stiffening sections 64 also form an outer contour of the scaffolding rosette 18. The reinforcing sections 64 on the outside each have one in the middle
- Indentation 68 on.
- the indentations 68 are each aligned with one of the through recesses 60.
- the outer reinforcement sections 64 each end at a distance from one another.
- An engagement area 72 is set up in each case in a corner area 70 of the scaffolding rosette between two adjacent outside reinforcement sections 64.
- the main section 62 is not surrounded by an outside reinforcing section 64.
- the engagement areas 72 allow a securing element 26 to be guided under the main section 62 and brought into contact with the main section 62 on the underside.
- One of the inner stiffening sections 66 is formed on each of the receiving recesses 24.
- the inner stiffening sections 66 surround the receiving recesses 24 in sections. The inner ones
- Receiving recesses 66 form an inner contour of the receiving recesses 24.
- the receiving recesses 24 with the inner stiffening sections 66 are each arranged radially inward as seen from one of the corner regions 70.
- a scaffolding bolt 14 inserted into one of the receiving recesses 24 therefore projects beyond the corresponding corner area 70 on the top side of the scaffolding rosette 18.
- the securing element 26 of the scaffolding bolt 18 can therefore be pivoted through the engagement area 72 under the main section 62 of the scaffolding rosette 18, so that the securing section 40 of the securing element 26 engages under the scaffolding rosette 18.

- the through recesses 60 of the framework rosette 14 are already present in the blank 74.
- the blank 74 has free edge regions 78 on the outside.
- the outer stiffening sections 64 are obtained from the outer free edge regions 78 by bending over, cf. Figure 7c.
- the blank 74 has inner free edge regions 80 at the punching 76.
- the inner stiffening sections 66 are obtained at the receiving recesses 24 from the inner free edge regions 80 by bending over, cf. Figure 7c.
- FIG. 9 shows the sequence of a method 100 for producing a scaffolding rosette 18. First, in a step 102, a flat
- step 106 the scaffolding rosette 18 can be welded to a scaffolding tube 16 so that a scaffolding post 12 is obtained.
- step 106 the method 100 is expanded to a manufacturing method 108 for a scaffolding post 12.
- the scaffolding tube 16 and the scaffolding rosette 18 can be made of steel or aluminum.
- the scaffold bar 14 can also consist of steel or aluminum.
