- these laterally telescoping sections are drawn in and thus not visible.
- laterally telescoping sections 54, 55 of the working platform 42 are drawn out
- Fig. 12 shows the state after a concreting step has been carried out, wherein after sufficient curing of the concrete, the formwork scaffolds 44 of the climbing units 3 of the left in Fig. 12 shown inner formwork have been moved away together with the attached thereon formwork panels 5 of the wall 2. The formwork panels 5 of the outer formwork are still on the wall 2.
- the formwork scaffolds 44 of the outer formwork are also moved away from the wall 2, as shown in Fig. 13. Furthermore, the carriages 37 of the climbing units 3 of the inner formwork are moved upwards by the height of a concreting step, as also shown in FIG. In addition, the carriages 37 of the climbing units 3 of the outer casing are also displaced upwards by this height.
- the carriages 37 of the climbing units 3 of the inner and outer formwork were in their lowermost positions. In the illustrated embodiment, starting from these lowest positions, they can be moved upwards by two concreting steps. For example, the height of a concreting step is 1, 5 m. The carriage 37 are thus moved by at least 3 m upwards. In order for the climbing units 3 three concreting stages can be performed without the climbing units 3 must be displaced as a whole relative to the wall 2 upwards.
- a preferred value for the height of a concreting step is in the range between 1 and 2 m.
- the formwork panels 5 themselves may be designed to be higher than a concreting step, so that in the case of two successive concreting stages an overlap in height occurs.
- FIG. 14 shows the state in which the formwork panels 5 of the inner formwork have again been moved to the surface of the wall 2 to be created in their height set for the next concreting step.
- the formwork panels 5 of the outer formwork are also raised to this height, but still lifted from the outer wall surface 11. As a result, they are brought to the outer wall surface 11.
- the concrete is poured and allowed to harden accordingly. This condition is shown in FIG.
- the climbing units 3 of the inner and outer formwork are displaced as a whole on the wall 2 upwards.
- the climbing rails 6 are raised by means of the climbing drives 7 as described earlier and fixed in the raised position.
- the formwork panels 5 preferably remain attached to the wall 2, wherein they are held at this with in the concrete of the wall 2 located anchors 9.
- a first possible procedure for the subsequent lifting of the respective climbing unit 3 is that the formwork panels 5 remain fixed on the formwork frame 44.
- the carriage 37 thus shifts when lifting the climbing tower 35 by means of the climbing drives 7 and the formwork tower 36 together with the climbing tower 35 relative to the wall 2 is not in its height.
- the formwork tower 36 is thus pulled through by the carriage 37 fixed in height. If the wall 2 has a curvature in the vertical direction, then the formwork frame 44 shifts relative to the working platform 42 along the guide rails 45 by a corresponding distance.
- the height of a concreting step is an integer multiple of both the height of the climbing climbing drives 7 and the height of the carriage drives 38.
- the distance of the knobs 14, 40 at 30 cm when the concreting height is 1, 5 m.
- FIGS. 19 to 21 A further embodiment is shown in FIGS. 19 to 21. This embodiment corresponds to the embodiment described above except for the following changes (analogous parts are given the same reference numerals):
- a respective climbing unit 3 is equipped in this embodiment with only one climbing drive 7, which cooperates with a climbing rail 6.
- the climbing drive 7 is in turn arranged on a (in this embodiment lower trained) climbing tower 35 of the climbing unit 3.
- the climbing tower 35 is provided with projecting arms 58, 59 on both sides, which are provided at their ends remote from the climbing tower 35 with rollers 60 for support on the wall 2 of the building.
- rollers 60 and sliding elements such as runners could be present.
- the outriggers 58, 59 are pivotally connected to the climbing tower 35 about vertical axes to allow for adaptation to changing radii of the structure.
- the pivot position is adjustable, for example by means of adjusting spindles 61. Also spring elements for pressing the boom to the wall of the structure could be provided.
- the at least one formwork panel 5 is suspended from an upper working platform 42 'connected to the carriage 37.
- This working platform 42' is pivotably connected to the carriage 37 about axes 50 'in order to adjust the inclination of the working platform 42' with respect to the horizontal can.
- This adjustment is made in this embodiment by a connection with a in their inclination relative to the horizontal adjustable lower working platform 62.
- This lower working platform 62 is also connected to horizontal axes 63 pivotally connected to the carriage 37. The adjustment of the inclination of the lower work platform 62 by means of adjusting spindles 64.
- the at least one formwork panel 5 is connected to the upper work platform 42 'via a sliding guide to allow a displacement of the at least one formwork panel 5 at right angles to the wall surface.
- guide rails 66 are attached to the upper work platform 4.2 'along which carriages 67 can be moved, which are connected to a carrier 68.
