[0002] Prefabricated box girders are bending members that are prefabricated by tensioning prestressed steel bars and then transported to the construction site for installation. The prefabricated box girder pedestal is the basic platform in the production process of prefabricated box girders. It is used to support the entire weight of the unformed box girder and ensure that the box girder is in a horizontal position during the forming process, so that the box girder has uniform mechanical strength after forming. The top surface and both sides of the pedestal must be flat and smooth to ensure the installation of the side formwork and the flatness of the bottom of the box girder, and to avoid water seepage into the base of the pedestal during construction, causing the pedestal to sink and crack.

[0003] At present, prefabricated box girder pedestals are usually made of reinforced concrete pedestals. Since the concrete pedestals need to be dismantled after use, the workload increases. When lifting the box girder, one end of the box girder needs to be lifted first, and then the other end contacts the pedestal, which can easily damage the box girder, thereby affecting the construction progress and reducing work efficiency. Therefore, an adjustable prefabricated box girder pedestal is urgently needed to improve the above problems. Utility Model Content

When the length of the pedestal is not enough, the staff takes out another pedestal. The adjustable prefabricated box girder pedestal is provided with a mounting plate 18. The staff moves another pedestal to insert the mounting plate 18 into the interior of the mounting groove 20. Then the staff connects the mounting plate 18 with the mounting groove 20 by screws, which can be adjusted according to the required length. After the adjustment is completed, the staff starts the motor 12 according to the ground conditions, and the output shaft of the motor 12 rotates. The rotation of the output shaft of the motor 12 can drive the threaded rod 13 to rotate. The rotation of the threaded rod 13 can drive the threaded sleeve 14 to move up and down.
