8. The large tonnage assembly type building jacking platform according to claim 7, wherein: the structure frame (101) faces to one side wall of the wedge block (7) and is attached to the side wall of the wedge block (7), and the wedge block (7) faces to one side wall of the structure column (3) and is attached to the side wall of the structure column (3).
9. A method for correcting a deviation of a large-tonnage assembly type building jacking platform, which is applied to the large-tonnage assembly type building jacking platform according to any one of claims 1 to 3, and is characterized by comprising the following steps:
step one, respectively installing a prefabricated dragging table (1) and a prefabricated supporting table (2) on a structural column (3), and installing a jack (4);
step two, breaking the structural column (3) between the prefabricated dragging table (1) and the prefabricated supporting table (2);
thirdly, jacking the structural column (3) through the prefabricated supporting platform (2) by using the jack (4) to enable the building to be aligned;
pouring a broken column part of the structural column (3) to complete integral repair of the structural column (3);
and fifthly, disassembling the jack (4), and disassembling the prefabricated dragging table (1) and the prefabricated supporting table (2).
10. The method for rectifying deviation of a large-tonnage building jacking platform according to claim 8, wherein the method comprises the following steps: in the first step, the surface of the structural column (3) is cleaned by using a high-pressure spray head, then the surface of the structural column (3) is roughened, the surface of the structural column (3) is cleaned again by using the high-pressure spray head after the roughening, and then the prefabricated dragging table (1) and the prefabricated supporting table (2) are installed.
