Composite forming car­ri­age

The adapt­able trav­elling composite bridge-deck formwork from a sin­gle sup­pli­er

The Doka composite forming car­ri­age makes for fast, safe con­struc­tion of bridges on which a con­crete deck slab is joined to a steel su­per­struc­ture. The trav­elling composite forming car­ri­age car­ries a large area of pre-as­sem­bled composite bridge-deck formwork that can be cy­cled with­out be­ing dis­man­tled. It stands out for its ex­cel­lent adapt­a­bil­i­ty to all cir­cum­s­tances, low-cost as­sem­b­ly from rentable stan­dard components, and its high work­place safe­ty.

Re­duces in­vest­ment costs
by us­ing rentable stan­dard components 

  • small num­ber of ver­satile, com­bin­able com­po­nent parts
  • ease of as­sem­b­ly
  • fast clos­ing and open­ing of formwork
  • high safe­ty stan­dards for rapid work­ing

Smooth con­struc­tion work­flow
thanks to easy han­dling 

  • low dead weight and high load ca­pac­i­ty
  • pour­ing in a week­ly cy­cle
  • en­tire unit is trav­elled in one piece
  • is adapt­able to slen­der struc­tures as well

Com­pre­hen­sive tailor-made so­lu­tions
for wide­ly dif­fer­ing shapes of bridge 

  • high-cal­i­bre so­lu­tions for all steel composite bridges, planned and sup­plied by a one-stop sup­pli­er
  • op­er­a­tio­n­al­ly re­li­able, as the forming car­ri­ages, shoring towers and work­ing plat­forms are all de­signed to work to­gether seam­less­ly

The new System beam 5.00m NG allows the Composite forming carriage to be adapted to the structure geometry even more flexibly.

System

Sim­ple sys­tem-grid

In the longitudinal direction of the bridge, the increment-grid of the Doka composite forming carriage is dictated by a 5 m long and 2 m high longitudinal girder. In the transverse direction, two transverse frameworks joined by an adjustment zone (compensation girders) permit any desired dimension. The adjustable spindle struts, and the large number of bolting positions in the steel girders, together make for optimum adaptability of the composite forming carriage. The new System beam NG allows more flexibility with the transverse frameworks in the longitudinal. This means that the transverse frameworks can be better positioned to take account of loads or geometrical parameters. In this way, the Composite forming carriage can be adapted to the structure geometry even more flexibly.

Safe­ty on the struc­ture

With its suspended finishing-work platform levels, the Doka composite forming carriage provides a high standard of safety. Only a few extra safety components are needed to create the ideal basis for an all-round enclosure.

Roller sup­ports for in­side formwork

  • for forward-jacking the inside formwork using the 'roller-drawer principle'

Un­limit­ed ad­justa­bil­i­ty op­tions

  • cantilever arm formwork can be adjusted in all directions by means of spindle struts
  • formwork is easy to close and open, using a two-part anchoring system

Formwork sys­tems for composite bridge-decks

Over­s­lung composite forming car­ri­age

This, the standard type of carriage, is a fast and safe way of constructing the concrete decking of composite bridges (on steel superstructures).

Un­der­s­lung composite forming car­ri­age

By providing barrier-free access to the entire roadway deck, this type of carriage ensures a high standard of safety, especially on wide bridge cross-sections with diagonal struts.

Bridge formwork Para­Top

For shorter superstructures and medium-length bridges involving only a few repositioning cycles, the crane-shiftable Bridge formwork ParaTop is available.

Cost-sav­ing cus­tom so­lu­tions

On request, the Doka Formwork Experts will also plan and design constructions for situations where space is severely limited, or for unusual cross-sections.
