Construction control device for pedestal pre-embedded steel plates of pre-stressed concrete box girder

The invention discloses a construction control device for pedestal pre-embedded steel plates of a pre-stressed concrete box girder, which comprises a basin-shaped box girder bottom mould pedestal steel plate. The construction control device is characterized in that: the pedestal pre-embedded steel plates with the same structure are placed in a groove of the box girder bottom mould pedestal steel plate so as to limit the horizontal displacement of the pedestal pre-embedded steel plates; a plurality of vertically-downward limiting adjusting bolts tightly withstand the pedestal pre-embedded steel plates upwards; and four pedestal anchor bolts tighten the pedestal pre-embedded steel plates downwards so as to limit the vertical displacement of the pedestal pre-embedded steel plates. The construction control device mainly realizes the slope adjustment of the pedestal pre-embedded steel plates through the tightening and releasing of the bolts, and the elongations of the bolts can be controlled precisely, so that the
