PRESTRESSED CONCRETE SLAB BRIDGE EQUIPPED WITH A FIXED COLUMN IN THE PC STRAND AND THIS CONSTRUCTION TECHNIQUE

摘要

PURPOSE: A prestressed concrete slab bridge with an external prestressed concrete steel wire mounting post and a construction method thereof are provided to lower the format height of a PSC slab bridge by the increment of eccentricity efficiency of an external prestressed concrete steel wire. CONSTITUTION: A prestressed concrete slab bridge with an external prestressed concrete steel wire mounting post comprises following steps. An external PC(Prestressed Concrete) steel wire fixing column(18) is installed on the upper surface of a slab of an inner support of a PSC slab bridge by pouring and curing concrete to have height and width. An external PC steel wire(22) is connected between the external PC steel wire and the slab. The external PC steel wire is strained.
