  • the stems 32.1 and 32.2 have in one of their respective lower ends 36.1, 37.1 up to the respective support surface 41.1 and 41.2 reaching stem portions, except for the area of the annular support surfaces 41.1 and 41.2 limited annular beads, an outer diameter 58.1 and 58.2, the here is the same size and here is about 48.3 millimeters.
  • the outer diameter 61.2 of the second pipe connector 54.2 corresponds to the outer diameter 61.1 of the pipe connector 54.1 and is therefore likewise slightly smaller than the inner diameter 59.2 of the second shaft 32.2 in the region of its lower end region 52.2.
  • FIGS. 12 a to 12 i show schematic views of various embodiments of the invention Gerüststellrahmen 12, which are all configured here with different lengths of pipe connectors 54.1 and 54.2. Such a configuration with a different length 55.1, 55.2 having pipe connectors 54.1, 54.2 prefers. Because then, when a succession of several similar scaffolding frame 21; 21.1, 21.2 on each other, the ends of a second frame rack 21.2, which are réellestecken on the associated ends of a first frame rack 21.1, supported in the mounted state on the respective support surfaces 41.1 and 41.2 of the first frame rack 21.1. It is understood, however, that alternatively, instead of different lengths of pipe connector, the lengths of the respective stems can be correspondingly different. Also, combinations of different lengths having pipe connectors on the one hand and different remaining lengths having stems are conceivable.
  • FIGS. 1 to 11 b shown embodiments of inventive scaffolding frame 21; 21.1, 21.2; 21 ', 21 "are in FIG. 12 a again schematically reproduced, so that reference can be made in this respect to the above statements.
  • FIG. 12b shows a schematic view of a similar U-shaped frame rack, but in contrast to the in FIG. 12 a schematically shown scaffolding frame the two different length pipe connectors 54.1 and 54.2 are respectively arranged at the lower end of the stems stems 32.1 and 32.2.
  • the Figure 12 c shows a schematic view of a similar scaffolding frame as the Figure 12 a , however, extend in the case of in FIG. 12c shown scaffolding frame the two different length pipe connector 54.1 and 54.2 viewed from the cross arm 35 from in opposite directions 45.1 and 46.2 away from it.
  • FIG. 12 e shows a schematic view of an H-shaped scaffolding frame, in which the two different length pipe connectors are designed and arranged the same, as in the in FIG. 12 a skeleton frame shown schematically.
  • this H-shaped scaffolding frame unlike in the FIGS. 12a to 12d shown scaffolding frame of the transverse arm 35 is arranged approximately in the region of the center of the two stems 32.1 and 32.2.
  • a distinguishing feature of the in Figs iguren 12 a to 12e schematically shown scaffolding frame is that the distance between the respective support surface 41.1, 41.2 and the respective, facing away from the respective pipe connector 54.1, 54.2 away stalk end of the stems 32.1 and 32.2, based on the respective scaffolding frame, is substantially the same size. In the case of these scaffolding positioning frames, therefore, the different lengths of the respective posts 32.1 and 32.2 result essentially only or exclusively from the different lengths of the tube connectors 54.1 and 54.2.
  • the Figures 12 f and 12 g show in each case schematic views of an H-shaped frame rack. This can, for the purpose of building a Gerhstrahmenan extract of several stacked scaffolding frame and / or for the purpose of building a scaffold, to be supplemented by an intermediate handle 33 which in the Figures 12 f and 12 g each shown dotted.
  • the two different length pipe connectors 54.1 and 54.2 each in the same direction 45.2, 46.2, respectively, each down.
  • the two pipe connectors 54.1 and 54.2 in opposite directions 45.1 and 46.2.
  • each two substantially the same length having stem parts of the stems 32.1 and 32.2 are provided, which together with the respective transverse arm 35 form a U-shaped frame structure.
  • the stem parts in the Figures 12 h and 12 i schematically shown H- or S-shaped scaffolding frame each having an L-shaped frame structure.
  • FIGS. 12 a to 12 i shown embodiments only show a part of the present invention possible different embodiments of scaffolding frame according to the invention, so that therefore also further advantageous constructions of scaffolding frame within the scope of this invention are conceivable.
  • scaffolding arrangements 22 are produced (cf. FIG. 1 ).
  • the stems are preferably 32.1, 32.2 or stem ends of a scaffolding frame 21.2 invention on the stems 32.1, 32.2 or the stem ends of a, preferably located underneath and preferably similar scaffolding frame 21.1 attached, so as the example of FIG. 1 outgoing scaffolding assembly 22 is illustrated.
  • a deformed or bent scaffold positioning frame can be arranged in a particularly simple manner, despite the deformation or bending, on a further scaffolding frame or scaffolding setting frame, in particular on a similar scaffold positioning frame. Attach.
  • FIGS. 1 to 12 i with differently long pipe connectors 54.1 and 54.2 designed scaffolding frame 21; 21.1, 21.2; 21 ', 21 "this can be done as follows:
  • the first stem part 39.1 of the first stem 32.1 of a second framework frame 21.2 to be stowed on a first frame staging frame 21.1 can be plugged onto the first, longer tube connector 54.1 of the first stem 32.1 of the first frame staging frame 21.1 by manually applying transverse forces to the second stem part 39.2 of the second handle 32.2 of the second frame rack 21.2 the free end 37.1 of the second handle portion 39.2 of the second handle 32.2 of the second frame rack 21.2 relative to the free end 37.2 of the second handle 32.2 and the second, shorter tube connector 54.2 of the first frame rack 21.1 into a Aufsteck ein can be moved, in which the free end 37.1 of the second handle part 39.2 of the second frame rack 21.2 and the free end 37.2 of the second handle 32.2 of the first frame rack 21.1 are opposite, so that plugging and the second handle portion 39.2 of the second Stem 32.2 of the second frame rack 21.2 on the second handle 32.2 of the first frame rack 21.1 is possible.
  • the free end 37.1 of the second stem part 39.2 of the second stem 32.2 of the second framework positioning frame 21.2 is relative to the free end 37.2 of the second stem by manual exertion of lateral forces on the second stem part 39.2 of the second stem 32.2 of the second framework positioning frame 21.2 32.2 of the first frame rack 21.2 moved to the slip-on, so that then the second handle part 39.2 of the second handle 32.2 of the second Gerüststellrahmens 21.2 on the second handle 37.2 of the first frame rack 21.1 is plugged or plugged.
  • stems 32.1 When setting up this frame rack 21; 21.1, 21.2 containing scaffold 20 are preferably the longer stems 32.1, ie here those stems 32.1, each having the longer pipe connector 54.1, each set up as outer or wandferne stems 32.1, while the other stems 32.2, which each have a correspondingly shorter length , So here each have the shorter pipe connector 54.2, be placed inside or close to the wall.
  • the scaffold erector in a simple manner manually by exerting lateral forces on the here near wall or inner handle 32.2 of ceremonisteckenden scaffolding frame 21.2 in the direction of the first stem 32.1 of this scaffolding frame 21.2 away, so for example in the direction of an immediately adjacent wall, in a Aufsteck ein be pressed, in which also a plugging of the second handle 32.2 of the second frame rack 21.2 on the shorter pipe connector 54.2 of the second handle 32.2 of the first frame rack 21.1 is possible, so that subsequently by manual exercise of forces acting in the direction of gravity of the second handle 32.2 of the second frame rack 21.2 together with the transverse arm 35 and the first handle 32.1 of this scaffold rack 21.2, and consequently this scaffolding rack 21.2 total, completely on the underlying scaffold rack 21.1 can be plugged.
  • both the lower end 36.1 of the first handle 32.1 and the lower end 37.1 of the second handle 32.2 of the scaffolding mounting frame 21.2 lie on the respective support surface 41.1 or 41.2 of the handles 32.1 and 32.2 of the first and lower scaffold positioning frames 21.1, respectively , Consequently, therefore, the second or upper frame rack 21.2 can be securely supported in the fully plugged state with both handle ends 36.1 and 37.1 on the support surfaces 41.1 and 41.2 of the stems 32.1 and 32.2 of the underlying or first scaffold rack 21.1.
