The utility model provides a special-shaped longitudinal beam structure of a low flatbed semitrailer, and relates to the field of semitrailers. The special-shaped longitudinal beam structure of the low flatbed semitrailer comprises a longitudinal beam main body, the side walls of the upper side and the lower side of the longitudinal beam main body are each provided with a flatbed beam, the two ends of the longitudinal beam main body are each symmetrically provided with a mounting side lug, the mounting side lugs are each provided with a mounting hole, and one end of the longitudinal beam main body is fixedly connected with a connecting frame. According to the special-shaped longitudinal beam structure of the low flatbed semitrailer, the longitudinal beam main body is supported and reinforced by matching the plurality of support rods with the plurality of top plates, so that the deformation of the flatbed beams on the upper side and the lower side of the longitudinal beam main body can be avoided; elastic defo
