[0042] A preferred embodiment of the invention is described in more detail in the following with the help of the attached figures. These show:

[0044] FIG. 2 a perspective view of the vertical post of FIG. 1 and a horizontal ledger connected to the vertical post, and

[0045] FIG. 3 a plan view of the arrangement of FIG. 2.

DETAILED DESCRIPTION

[0046] The vertical post 10 according to the present invention, shown in FIG. 1, has a tube 11 with a longitudinal axis A and a tube section 12 on which a rosette-like connector element 20 is arranged for connecting the vertical post 10 to a horizontal ledger 40 (see FIG. 2). In this respect, the connector element 20 has a plurality of receiving openings 21, which are arranged at equal angular distances from one another.

[0047] Above and below the connector element 20, openings 16 are provided in the tube section 12, which in the present case are designed as an elongated hole. A bolt-like reinforcing element 30 is inserted into each of the openings 16, which runs transverse to the longitudinal axis A of the tube 11. The openings 16 each pass through the wall of the tube 11, so that the reinforcing elements 30 can each be inserted into the openings 16 from the outside. By forming the openings 16 as slots, the reinforcing elements 30 inserted therein can be easily welded to the tube 11. The welding ensures a firm connection between the reinforcing elements 30 and the vertical post 10, so that the reinforcing elements 30 do not fall out of the openings 16. As can be seen from FIG. 1, the reinforcing elements 30 and openings remain visible so that the vertical post 10 can be identified as a locally reinforced vertical post 10.

[0048] The position of the reinforcing elements 30 is predetermined by a contact area 13 of the vertical post 10 with a horizontal ledger 40, which is later connected to the vertical post 10 via the connector element 20. The two reinforcing elements 30 arranged above and below the connector element 20 run parallel to each other. This means that the openings 16 are located above one another at an axial distance from one another. The same applies to one of the four receiving openings 21 of the connector element 20, so that it is ensured that the horizontal ledger 40 connected thereto comes to rest in the contact areas 13 on the vertical post 10. The vertical post 10 is thus locally reinforced by the reinforcing elements 30 in the contact areas 13.

[0049] FIG. 2 shows a scaffold 100 in part, which comprises the vertical post 10 of FIG. 1 as well as a horizontal ledger 40. The horizontal ledger 40 has connecting means 41 that engage in a receiving opening 21 of the connector element 20. The connecting means 41 comprise a wedge element 43, with the aid of which the connecting means 41 are locked in the receiving opening 41. The wedge element 43 presses the connecting means 41 against the vertical post 10, so that these come to rest in a first contact area 13 on the vertical post 10. Since a first reinforcing element 30 is arranged in the first contact area 13, the load introduced by the horizontal ledger 40 is absorbed by the reinforcing element 30. This means that the load-bearing capacity of the vertical post 10 increases in the first contact area 13. In a second contact area 13, in which the horizontal ledger 40 also comes into contact with the vertical post 10 via a concave end-face area 42, the load introduced is absorbed by the second reinforcing element 30 arranged in this area. This also contributes to increasing the load-bearing capacity of the vertical post 10.

[0050] When the horizontal ledger 40 is attached, at least the openings 16, which are designed as slots, remain visible. The two reinforcing elements 30 are received in these openings. This means that it is visible to everyone that the vertical post 10 of the scaffold 100 is locally reinforced.

[0051] FIG. 3 shows the scaffold 100 in a plan view of the vertical post 10. FIG. 3 makes it clear that the two reinforcing elements 30 each extend from a first wall area 14 to a second wall area 15, which is preferably located diametrically opposite the first wall area 14. This is particularly advantageous if the horizontal ledger 40 is connected in the manner shown, so that a longitudinal axis A of the horizontal ledger 40 intersects the longitudinal axis A of the tube 11 of the vertical post 10. Because then the two reinforcing elements 30 are each arranged in the extension of the horizontal ledger 40, and in fact in the center with respect to the longitudinal axis A of the horizontal ledger 40. That means that in the plan projection, the longitudinal axes of the two reinforcing elements 30 coincide with the longitudinal axis A of the horizontal ledger 40.

[0052] In FIG. 3, the horizontal ledger 40 connects to the vertical post 10 from the right. If the scaffold 100 is extended, another horizontal ledger 40 can be connected from the left. Since the reinforcing elements 30 each extend from the first wall area 14 to the second wall area 15, which in the present case is diametrically opposed to the first wall area 14, the reinforcing elements 30 achieve an improved load-bearing capacity of the vertical post 10, regardless of whether the connection of a horizontal ledger 40 is made from the right and/or from the left.

[0053] The rosette-like connector element 20 shown also allows two further horizontal ledgers 40 (not shown) to be connected, which run transversely to the horizontal ledger 40 so that they connect to the vertical post 10 from above or below-based on FIG. 3. In order to further optimize the load-bearing capacity of the vertical post 10, two further reinforcing elements 30 (not shown) can therefore be provided, which run perpendicular to the reinforcing elements 30 shown or in the extension of the further (not shown) horizontal or crossbars. The arrangement is then offset in height and angle to the existing reinforcing elements 30. This results in a cross-shaped arrangement, ideally based on the scaffold axes (not shown) of the scaffold 100.
