Novel rigid frame bridge corbel bracket mechanism, construction method and finished bridge linear deformation control method of novel rigid frame bridge corbel bracket mechanism

The invention relates to the technical field of bridge construction, in particular to a novel rigid frame bridge corbel bracket mechanism, a construction method and a finished bridge linear deformation control method.The novel rigid frame bridge corbel bracket mechanism comprises anti-shearing steel bars pre-buried on the sides, away from each other, of two concrete parts, and upper supporting legs are fixedly installed on the anti-shearing steel bars and are obliquely arranged; an upper bracket is mounted at the top of the upper supporting leg; a bracket bracket and a steel truss are adopted as a formwork support, a tower column outer side formwork utilizes a creeping formwork outer side formwork, the truss and a beam body inner and outer formwork are all large steel formworks, pouring is completed on the bracket in three times, and the cantilever support is safe and stable; and after prepressing, gaps and inelastic deformation of vertical rod pieces of the bracket under the prepressing load effect are basic
