Abstract: PURPOSE: A connection structure of an UHPC precast floor plate and a construction method using reinforcing bar joints into tapered recessed parts are provided to optimally integrate UHPC floor plates and a girder by connecting both UHPC floor plates and the girder with reinforcing bars. CONSTITUTION: A connection structure of an UHPC precast floor plate comprises recessed parts(11) and reinforcing bars(3). The recessed parts are formed on the top surface of the end of one UHPC floor plate(1a) facing the other UHPC floor plate(1b), and are traversely recessed from the top surface of the UHPC floor plate starting from the top surface of the end. The recessed parts are formed in a longitudinal direction of a girder(2). The reinforcing bars are projected from the end of the other UHPC floor plate. If both UHPC floor plates are arranged on both sides of the girder, the other end of the reinforcing bars is positioned in the recessed part and concrete(5) is placed on the upper part of the girder between both UHPC floor plates.
