A half section precast cantilever deck and a construction method of a bridge deck are provided to reduce accidents caused by aerial work and to cut down on the cost of construction and to prevent delay in construction, to prevent generation of construction waste such as timbering, a form, etc. after use. A half section precast cantilever deck is manufactured with a half section precast member provided with a hanger bar(15), and installed to the upper side of a girder(1) integrally by coupling the hanger bar to a fixing member(30) provided to an outermost girder of a bridge by a steel bar(41a) connected to a length adjustment device(40) to form a cantilever portion on a bridge deck at the outside of the bridge girder. A construction method of a half section precast cantilever deck comprises the steps of: pre-manufacturing a precast cantilever deck; pre-fixing a fixing member to the upper part of a girder; coupling the precast cantilever deck with the outermost girder of a bridge strongly by pulling up the precast cantilever deck to the outermost girder of a bridge and placing the end of the precast cantilever deck on the upper part of the girder, and connecting a hanger bar with the fixing member and introducing tensile force for making the precast cantilever deck adhere closely to the upper part of the girder; and placing concrete on the upper part of the girder and the top(11) of the precast cantilever deck. |
