PURPOSE: A bridge slab curing device in winter is provided to prevent a crack caused by freezing and thawing and initial frost damage when concreting in the winter time and to control a temperature crack caused by hydrate heat when constructing a large-sized structure by keeping optimum temperature and humidity by jetting steam when curing the concrete surface in winter. CONSTITUTION: In a slab bridge truss(100) for constructing a bridge continuously by moving tables(101)(102)(103) composed of legs(111), a frame(112), an upper truss(113) and a form(114) along an orbit, the bridge slab curing device in the winter time comprises: a curing truss(1) installed to the upper side of the form(114) of the tables(101)(102)(103) to form a frame of the open air intercepting curtain; a steam pipe(2) arranged in the curing truss(1) and provided with many steam jet nozzles(20) downward; and a steam boiler(3) and a tank(4) for supplying steam toward the steam pipe(2).
