Staged concrete bridge mobile platform - has disc carriers with rail supports on girder sides

摘要

The mobile platform is for sectional free-forwarding construction of bridge structures made of reinforced or prestressed concrete. It has a top laterally-cantilevered roadway slab of closed box cross-section. It comprises a concreting platform, bearing the superstructure form-work, below and projecting beyond the existing superstructure (2). This can move on outside rails on the existing part. On both sides of the girders it is fitted with carrier discs, joined to form a three-dimensional carrier with cross-beams and/or diagonal struts. The concreting platform is attached to the lower part. This is universally applicable, for erection of structures with vertical or sloping main girder walls, and parallel or vaulted main girders.
