[0029] Four high bosses 1.6 and four low bosses 1.12 with the same height are arranged along the arc-shaped outer edge of the long end truss structure 1.1. The high bosses 1.6 and the low bosses 1.12 are correspondingly distributed on both sides of the auxiliary plate 1.11, and an equal-diameter through hole 1.7 is designed in the center of the boss.

[0030] The four high bosses 1.6 on the outer edge of the long-size end truss structure 1.1 are connected by nine reinforcing ribs, including reinforcing ribs a1.8, b1.9 and c1.10. Among them, three reinforcing ribs a1.8 are along an approximately arc-shaped direction, four reinforcing ribs b1.19 connect the high bosses 1.6 and the long beam 1.3, and two oblique reinforcing ribs c1.10 connect the two middle high bosses 1.6 and the long beam 1.3, and form a truss structure with the three nearest reinforcing ribs.
