The row of stating hungry ghosts who spit fire includes the rectangle row hungry ghosts who spit fire of spaced setting and triangle row hungry ghosts who spit fire, and the triangle row hungry ghosts who spit fire is included on two
Under the identical right angled triangle row hungry ghosts who spit fire that is oppositely arranged, the two right angled triangles row hungry ghosts who spit fire's being oppositely arranged up and down is oblique
Covering between side forms shearing resistance oblique pull band.
Further, load stringer is equipped between the adjacent row hungry ghosts who spit fire.
Further, in the adjacent two triangle row hungry ghosts who spit fire, the shearing resistance oblique pull of one of triangle row hungry ghosts who spit fire
Band is Right deviation shearing resistance oblique pull band, the shearing resistance oblique pull band of another triangle row hungry ghosts who spit fire is left-leaning shearing resistance oblique pull band.
Further, the number of the rectangle row hungry ghosts who spit fire is 20, and the number of the triangle row hungry ghosts who spit fire is 20.
Beneficial effects of the present invention：Subtract oblique pull band by setting to resist, both ensure that existing vehicle interstage section row hungry ghosts who spit fire's
Flame area is arranged, and the shear resistance of rectangle row hungry ghosts who spit fire greatly improved, the torsion stiffness of interstage section is improved, solves especially
This conspicuous contradiction that middle-size and small-size vehicle interstage section row's flame area and torsion stiffness must be taken into account.The structure type of the present invention simultaneously
Simple novel, principle is reliable, need not change original technique assembling link, technique realizability is good, and increased weight generation
Valency very little solves the problems, such as that existing interstage section row hungry ghosts who spit fire's anti-torsion ability is insufficient well.
