Abstract
The utility model discloses a combinatory concrete prefabricated tower crane base with an integrated stress, which relates to the technical field of the base component of tower crane and is composed of a center piece, four extremity pieces, and transition pieces that are respectively connected between each extremity piece and the center piece and an oblique piece that is arranged between every two adjacent extremity pieces. The lower surface of the oblique piece and the lower surface of the extremity piece are arranged at the same horizontal plane, while the two ends of the oblique piece are respectively connected on the two adjacent extremity pieces. The utility model optimizes the exterior size of the combinatory base component and is convenient for transiting, but also forms a similar 'pane' structure where the peripheric oblique pieces and the center cross body assume forces simultaneously, so the gravity and overturning force assumed by the tower crane base are distributed on the foundation with a larger area, thereby strengthening the safety and stability of the tower crane base.
