Steel bar binding mould of prefabricated box girder top plate

The utility model belongs to the field of prefabricated box girder construction, and particularly relates to a steel bar binding mould of a prefabricated box girder top plate, which comprises a comb-shaped plate, more than two positioning rings are arranged on one surface of the comb-shaped plate, comb teeth of the comb-shaped plate face upwards, and the distance between the comb teeth is matchedwith a steel bar to be bound. The mould further comprises a positioning steel pipe matched with the positioning ring, the inner diameter of the positioning steel pipe is the same as that of the positioning ring, when the mould is used, the positioning steel pipe is welded to a box girder formwork, the positioning steel pipe and the positioning ring are coaxially arranged, and the positioning steelpipe and the positioning ring are positioned by inserting a right-angle bolt. By adopting the mould, the precision of steel bar binding can be improved, the construction speed is high, the construction progress can be acceler
