  • the facade scaffolding 50 has vertical frames 56 with parallel, transversely spaced vertical uprights 58.1, each connected to a crossbar 60.1 at the upper end via a gusset plate 64.
  • a cross profile 70 connects the two vertical uprights 58.1 at the lower end.
  • the railing post 10.1 is first hooked into the existing railing post 68 with its third connection device 16 from above in the connection area of the existing railing rails 16 to the vertical post 58.1 and is initially in an outwardly inclined position, in which the second connection device 14 with its rotatable form-locking unit 26 rests against the outer contour of the vertical post 58.1.
  • the rotatable form-locking unit 26 opens until the Fig. 15 shown vertical end position of the railing post 10.1 is reached. In this position, the rotatable form-locking unit 26 snaps into the closed position due to the effect of the elastic element and the vertical post 58.1 is positively enclosed by the second connection device 14 and thus locked.
  • Figures 14 and 15 The detachably connectable telescopic railing bars of the leading railing are not shown.
  • the connection situation of the railing post 10.1 to the vertical post 58.1 shown corresponds to the connection of the second connection device 14 in the detailed illustration according to Fig. 4 and with regard to the third connection device 16 of the detailed illustration according to Fig. 5 .
  • FIGS 16 to 19 show the use of the railing post 10.1 in the context of a leading railing with telescopic railing bars connected to both first connecting devices 12.1 20 in different assembly positions in one scaffold bay ( Figures 16 to 19 ) and in three scaffolding fields ( Fig. 18 and 19 ).
  • Fig. 16 shows an intermediate assembly state of a scaffold bay of a lower level 54 of the scaffold 50, in which the left railing post 10.1 is still in a lower assembly position and the right railing post 10.1 is already connected in its final position to secure an upper scaffold level 52.
  • the Fig. 17 shows the state in which the left railing post 10.1 is also connected in the (temporary) upper position.
  • Fig. 18 shows the state of a connected leading railing with three scaffold bays of the scaffold 50 according to the assembly state of Fig. 17 .
  • Fig. 19 shows the further assembly progress starting from the state according to Fig. 18 .
  • Planks 62 are hooked into the crossbars 60.1 of the vertical frames 56, so that the upper scaffolding level 52 can be accessed by the assembly personnel, while at the same time side protection is provided by the leading railing with its railing posts 10.1 and the temporary railing beams 20.
  • vertical frames 56 are placed on the vertical frames 56 of the lower scaffolding level 54, whereby the railing posts 10.1 are then successively moved to the height of the upper scaffolding level 53 with respect to the further assembly progress, so that side protection is provided for a further scaffolding level to be assembled.
  • Fig. 20 The connection of a guardrail post 10.2 to the vertical standard 58.2 of a modular scaffold, for example the Layher Allround scaffolding ® (registered trademark) system, is shown.
  • Fig. 20 The connection situation of the second connection device 14 shown corresponds to the detailed representation of Fig. 6 and the connection situation of the third connection device 16 corresponds to the detailed representation of Fig. 7 .
  • the modular scaffolding consists of two parallel, spaced-apart vertical uprights 58.2 with rosettes 66 arranged in a grid pattern in the longitudinal direction L, which are connected to each other in the upper and lower end areas via crossbars 60.2 using a wedge head connection.
  • longitudinal bars 63 are connected to the rosettes 66 in the upper and lower end areas of the vertical upright 58.2.
  • existing guardrails 68 are connected to the rosettes 66.
  • the Fig. 21 shows a third embodiment of a railing post 10.3, which basically has the same construction as the railing post 10.2 according to Fig. 2 , but with the following differences.
  • the railing post 10.3 has no safety stop unit 32 and the third connection device 16 - shown in more detail in Fig. 22 - differs from the third connection device according to Fig. 3 in that a projection unit 38.1 is formed onto the first connection area 34, pointing downward in the longitudinal direction L, which is designed as a curved profile unit, wherein the curvature contour is configured such that the free end area of the projection unit 38.1 is curved toward the railing post 10.3.
  • Identical components bear the same reference numerals and will not be explained again.
  • the railing post 10.3 has the advantage that it can be used with both façade scaffolding (Layher Blitz Gerüst ® (registered trademark) system) and modular scaffolding (Layher Allroundgerüst ® (registered trademark) system). Assembly and disassembly on a vertical standard 58.1, 58.2 of a scaffold 50 is carried out in the same manner as described above, just as with the railing posts 10.1 and 10.2.
  • the curved projection unit 38 When mounting the railing post 10.3 to a vertical post 58.1 with rosettes 66, the curved projection unit 38 is threaded into a recess in the rosette, then the railing post 10.3 is moved into the vertical position, and the second connection device 14 is connected to the vertical post 58.1. In this final assembly position, the railing post 10.3 is secured against upward lifting in the longitudinal/vertical direction, as the curved projection unit 38.1 blocks any upward movement.
  • a fourth embodiment of a railing post 10.4 is shown, which basically has the same structure as the railing post 10.3 according to Fig. 21 , but with the difference that there is no second connection area 36 on the third connection device 16, but rather it consists solely of the first connection area 34 with a curved projection unit 38.1 formed on the underside.
  • Such a railing post 10.4 is suitable for connection to a vertical post 58.2 of a modular scaffold (Layher Allroundgerüst ® (registered trademark)). The assembly process is analogous to that described above.
  • a variant not shown relates to an alternative structurally different design of the railing post 10.3, whereby the Fig. 25 shown first connection device 12.2 and second connection device 14 is used and With regard to the second connection device 14, the rotary actuating devices 22.1 and 22.2, respectively, and the rotatable shaft are omitted.
  • the structural design of the first and second connection devices 12.2, 14 merely needs to be designed such that they fulfill the required functionality, i.e., temporary railing stiles can be releasably connected to the first connection device 12.2, and the second connection device 14 can be releasably connected to a vertical post in a lockable manner.
