Abstract
The utility model discloses a small box girder concrete pouring mold which comprises a pedestal, a support, an outer mold and an inner mold. The inner mold is of a detachable structure and provided with an open bottom and further comprises a shaping plate connected on a bottom opening of the inner mold through a plurality of blocks, wherein the shaping plate is rectangular and provided with at least four first raised parts and at least two second raised parts which protrude upward. The first raised parts are symmetrically distributed along corners of the shaping plate, the second raised parts are symmetrically distributed along in the length direction of the shaping plate, the first raised parts are provided with first connecting holes in the direction identical to the length direction of the shaping plate and used for connecting adjacent shaping plates, and the second raised parts are provided with second connecting holes in the direction identical to the width direction of the shaping plate and used for connecting the shaping plate in the inner mold. Due to the fact that the shaping plate is added, the full-opened inner mold becomes a closed structure, the adverse influence caused by concrete mobility during girder pouring can be greatly reduced and even eliminated, and concrete spillover, uneven girder bottom and other situations are completely eradicated.
