  • Construction method for prestressed concrete girder bridges
    Patent number: 7373683
    Abstract: A construction method for simple bridges or continuous bridges using prestressed concrete girder (PSC girder) and precast slabs (PSC slabs) where prestress is applied to the lower portion of the center of the girder. bridges of low clearance and long span are constructed by preventing a loss of prestress due to load of the slabs and relieving excessive compression force generated on the upper edge portion of the center of the girder during the construction of the bridge.

  • Construction method for psc girder bridges
    Publication number: 20070056123
    Abstract: The present invention relates to a construction method for simple bridges or continuous bridges using prestressed concrete girder (PSC girder) and precast slabs (PSC slabs). The PSC girder, where prestress is applied to the lower portion of the center of the girder by the first tense, is spanned between piers, and the second tense is performed during the PSC slabs are put on the PSC girders, and hence, the present invention can construct bridges of low clearance and long span by preventing a loss of prestress due to load of the slabs and relieving excessive compression force generated on the upper edge portion of the center of the girder during the construction of the bridge.
