THE STRUCTURE THAT SEPARATED AND INTEGRATED MUTUAL BETWEEN EXPANSION JOINT, PRESTRESSED NON-SHRINKAGE CONCRETE AND BRIDGE DECK SLAB, THE CONSTRUCTION METHOD OF THIS

摘要

A structure separated/integrated with an expansion joint device, a prestress non-shrinkage concrete section and a bridge deck slab is provided to prevent a decrease in the durability of a bridge, to separate each component easily and to integrate each component easily using prestress bolts at ordinary times. The invention relates to a structure formed by assembling a reinforcing bar on a bridge deck slab, installing an anchor socket device(16) on a prestress bolt(26) for integrating with non-shrinkage concrete, installing forms for forming a non-shrinkage concrete section and placing bridge deck slab concrete on a block-outed cross section, attaching a film plate(18) having the damping and separating function on the boundary of the bridge deck slab, attaching a form-cum-plate(19) on the film plate for forming a cross section of the non-shrinkage concrete section, installing a PVC duct(20) for inserting a prestress bolt to the top of the anchor socket device, arranging reinforcing bars(22) for reinforcing non-shrinkage concrete, installing an expansion joint device(24) to the play caused by a variation of temperature, placing and curing non-shrinkage concrete on the block-outed cross section, inserting the prestress bolt to the PVC duct, applying tensile force to the prestress bolt and fixing to the anchor socket device installed on the bridge deck slab, and then fastening on the top of the prestress bolt with a washer(28) and a nut(30), forming prestress concrete where prestress compressive stress is applied on the non-shrinkage concrete section in advance, placing resins(32) on the prestress bolt and a groove formed on the top of the prestress bolt to prevent corrosion and to fill up a stepped part of the groove, and laying a perforated pipe(36) on a part where a bridge deck pavement section(34) meets to dispose of infiltration water.
