s32, increasing the plate thicknesses of the dash panel 21 and the rear wall panel 22 corresponding to the position of the second hanger row 23, and increasing the plate thickness of the deck surface near the second hanger row 23.
In this embodiment, since the weight of the second block 2 is large, the thicknesses of the dash panel 21, the rear wall panel 22, and the deck surface are increased, so that the dash panel 21, the rear wall panel 22, and the deck surface can be prevented from being deformed during the hoisting process, and the structural rigidity of the second block 2 is enhanced.
In one embodiment, there are upper and lower steps at some second hanging points 25 of the front and rear wall panels 21 and 22, and a second hanging row 23 stepped up and down is provided at the second hanging points 25.
