continuous structure system type precast prestressed concrete single slab girder bridge connecting and supporting the same bridge with one point supporting structure or strongly coupled integrated structure

摘要

The subject innovation is produced the bottom plate a to the slab in the upper flange integral with the girder tension the primary liner in Chapter produce girders consisting of the stomach and the bottom flange fixing precast PSC single slab girder, said precast PSC single slab girders a shift and subsequently, and subsequently installed connecting the girders the girder corner angle the bridge fittings and ganggyeol while mounted between piers, and connect the intervals between the girder and the bonding ganggyeol reinforced active prevention system by cast-in-place high strength concrete, and then , in the second continuous justify the slab plans ground floor a steel wire to tension and fixing to a building in cross-continuous structural system, and then, alternately, and the supporting structure for the said girder sequencing from the pier 1 point, or with the girder and the girder and the girder by installing a pier or abutment with ganggyeol integrally continuous structure having a Multi-free boundary conditions ganggyeol integrally cast structure PSC One way to build a slab girder and to the precast PSC to produce a single slab girder in a formal precast, dies for fabrication of the girder is to apply such cross-section changes in the location, square change position, the curvature change position introducing the hinge system and the removable clamp and the ever position adjustment of the support, and the altitude change is possible in jack connected to a support for supporting the formwork, which also produced a standardized formwork excellent only and sanctuary St. applicable section It relates how.
