The invention relates to the field of construction technologies for bridges, particularly relates to the field of construction technologies for 2209 beams of traffic bridges (2012), and particularly discloses a cast-in-situ construction method for 2209 beam flange plates. The cast-in-situ construction method includes supporting and erecting formworks by the aid of arranged cantilever hanging processes; laying H-section steel to be used as cantilevers below steel rails on bridge decks; fixing another piece of H-section steel to be used as a framework to the lower side of each cantilever; laying set-shaped formworks. The cast-in-situ construction method has the advantages that the formworks for 2209 beam bridge deck slabs can be assembled by the aid of simple and common materials, assembly structures are simple and stable, only few constructors are required and can easily implement the in-situ construction method, and the in-situ construction method is low in construction cost; tracks and station tracks do not
