- a framework truss with extremely large dimensions whose Length is designed so that it is the span of the can bridge the later structure, similar to one Formwork.
- the scaffold is used for storage and Advancing a formwork, with the help of which successively Structural sections are concreted.
- the entire load of Formwork and the fresh concrete brought in must be from the Scaffold girders added and into the already manufactured Building sections are forwarded. Because of the high Load, in particular bending stress, as well as the large
- the span of the scaffold must be very strong are carried out, which makes this complex and expensive and furthermore, its handling is difficult.
- DE 36 20 587 C1 also discloses one method and one Device for the sectional production of Free-standing bridge superstructures.
- the device has a stem cantilever and formwork, however has no floor formwork, since the structure floor is covered by a Finished part is provided.
- the structural floor is in the anchored previous section before the rest Parts of the new construction phase will be manufactured.
- the method has the disadvantage that it is neither for In-situ concrete for any cross-sectional shape, such as for example, full cross sections is also suitable.
- the cantilever must also be comparatively strong be carried out to the weight of the formwork as well as the heavyweight precast concrete before tensioning take.
- the present invention is based on the idea that Load transfer in a formwork device optimize that stress to a large extent about tensile and / or compressive forces, and not just about Bending moments and shear forces in the previous ones Structural sections is derived. This will realized according to the invention in that the first Formwork equipment in the area of the new construction phase by means of at least one tension and / or compression strut connected to at least one preceding structural section is.
