Innovative, flexible bridge formwork systems | World

Innovative formwork systems have been used to construct a variety of bridge structures` Patrick Smith reports` As part of the work on Germany's new A4 autobahn near Eisenach· the contracting joint venture awarded the formwork contract for two of the three viaducts to Doka` What makes this assignment so special to the company is that although the two steel composite bridges each have very ```

An ACI Manual Formwork for

previous lift of pier concrete: For light beam caps on circular pier shafts, friction collars (Fig: 15:17) can be used to carry all or part of the cap formwork: 15:3 Superstructures Bridge superstructures include girders, a deck or roadway, curbs, sidewalks, and railings or parapets: Concrete bridge decks may be simple slabs for short spans or

precast segmental box girder moulds for prestressed span

Precast girder formwork has advantages of high-precision, simple structure,retractile,easy-demoulding and simple operation` It can be hoisted or dragged to casting site integrally, and demoulded integrally or piecemeal after concrete achieving the strength, then pull out the inner mould from the girder`


forms for T-beam` steel girder` and precast concrete girder bridges` and overhangs are usually of conventional joist and plywood construction. The bridge superstructure dictates the method of support for the forms. See Figures 2.1-4` 2.1-5` and 2.1-6 for examples of a slab bridge` a steel girder bridge` and a T-beam bridge. Figures 2.1-7 ...
