By embedding a plurality of positioning bolts 204 in the base concrete layer of the factory building, the plurality of positioning bolts 204 are arranged in a neat and spaced manner along the arrangement direction of the anti-cracking device. Then, the mounting plate 2 is inserted with the positioning bolt 204 and fixed with the second nut 205, so that the mounting plate 2 is fixed on the base concrete of the factory building.
