Just as different as the methods of bridge construction are the requirements regarding the production of cantilevered parapets. Many circumstances influence the choice of the formwork systems for an optimal construction process.
Catered to the requirements of the jobsite and the structure, the VARIOKIT engineering construction kit offers the right and structurally optimal solution in the form of:
Individual brackets with formwork unit, suspended at the lower side of the cantilever
A launched traveler with formwork unit moving on the lower side of the cantilever
A carriage moving on the bridge with formwork suspended from a gallows construction
Here, a carriage travels on the completed superstructure and features 5.50 m long formwork sections in standard cases. Several carriages are coupled together in order to achieve the required length of the concreting section.
The carriages move by means of heavy-duty rollers on the U-profiles positioned on the bridge.
The loads are carried on a gallows construction and ballast. As a result, no anchors are needed in the superstructure.
Standard deployment is with 4 carriages of 5.50 m each
With this configuration, parapets can be realized up to a height of w/h = 50/80 cm. For this, the ballast is merely modified for the respective loads.
Larger parapets can be realized thanks to the VARIOKIT modular construction kit as well as by simply changing the geometry on the carriage.
