  • a so-called Gesimskappe is formulated in formwork technology to the laterally projecting edges of the cantilever.
  • the Gesimskappe usually extends to well below the edge of the cantilever, and is above the edge of the support plate often used to form a walkway.
  • the space that is to take the Gesimskappe must be converted with formwork elements and filled with liquid concrete. After curing of the liquid concrete, the formwork elements can be removed.
  • Gesimskappen be concreted in sections on the cantilever.
  • a working or assembly platform is arranged on the edge of the cantilever, on which the required formwork element are attached. After completion of the concreting work of a section, the assembly platform is moved to the next adjacent section to be concreted,
  • the fitting and stripping of the formwork elements or the assembly and disassembly of the auxiliary structure for fastening the skin elements in a desired position is a complex manual process, which costs a lot of time, and repeats itself on each Verimskappenabrough to be concreted.
  • a formwork device of the type mentioned which is characterized in that a pillar element is arranged on the working platform base, which is connected to the working platform, wherein a formwork holder is mounted on the pillar element, the formwork holder can be moved back and forth in a first direction running away from the working platform base surface relative to the column element, the formwork holder being movable in the first direction by means of a first adjusting device, the formwork holder has a tilting bearing about which the formwork holder can be tilted on the pillar element, the formwork holder being tiltable by tilting means, the inner shield is attached to the formwork holder, an outside tag carrier is mounted on the formwork holder, the outside tag carrier being movable in a second direction opposite the form holder from the inside shield, the outside label carrier being movable in the second direction by means of a second adjusting device, and the outside shield being fastened to the outside shield is.

This makes it possible to quickly switch on and off from a safe position.
  • the operability of one side of the Gesimskappe or one side of the formwork holder has the further advantage that the entire work platform can be constructed more compact and can do without a second, lower floor. Thus, the entire height of the work platform is smaller. This, in turn, is particularly advantageous, since it is then possible to work in the area of low, light heights of a bridge (for example in the immediate vicinity of the bridge abutment, in the case of road or rail traffic management there, for example on river courses).
  • a preferred embodiment of the shuttering device is characterized in that the tilting means comprise a switching element, that by means of the tilting means a first end of the switching element relative to the formwork holder is movable, wherein a second end of the switching element engages behind the pillar element or, and that the longitudinal line of the mediating member is spaced from the first to the second end of the tilting bearing.
