Prefabricated pedestal of pi-shaped beam

The utility model relates to the technical field of beam making pedestals, and particularly discloses a prefabricated pedestal of a pi beam. A prefabricated pedestal of a pi-shaped beam comprises two expanded foundations and a plurality of force transmission longitudinal beams. The two ends of the force transmission longitudinal beams are fixedly carried on the two expanded foundations respectively, two parallel foundation pedestal blocks are arranged between every two adjacent force transmission longitudinal beams, a plurality of connecting cross beams are arranged at the lower ends of the force transmission longitudinal beams, the connecting cross beams are all perpendicular to the force transmission longitudinal beams, and the connecting cross beams are perpendicular to the force transmission longitudinal beams. And the plurality of connecting cross beams are uniformly distributed along the beam length direction of the force transmission longitudinal beams. According to the prefabricated pedestal of the pi
