As shown in figure 1, the rolling mould 1 is made of a round steel plate, the steel plate is used for installing and fixing a cross box, a cross box fixing hole 3 is formed in the mould, and the size of the cross box fixing hole 3 is set according to the cross section of the cross box of the ultra-large thick plate. The fixed hole is slightly larger than the cross box, and the local size difference is compensated by the inclined iron 7 during fixing. The cross-shaped member is fixed by inserting the wedge 7 into the gap between the cross-shaped box fixing hole 3 and the wing plate 5. As shown in fig. 1, the cross box fixing hole 3 includes an upper notch 31, a lower notch 33, a left notch 34 and a right notch 32, and in order to reduce the overall weight of the rolling fixture 1, the notches and the notch side walls are provided with chamfer angles. Four hoisting holes 2 are further formed in the rolling mould 1, and when the whole flat hoisting is needed, hoisting hooks of hoisting tools are directly hung on the hoisting holes 2.
