Preferably, the top flange of described horizontal stiffness beam is connected on the second horizontal flue bottom walls by the pistol integrated circuit board.

Preferably, described vertical truss comprises the beam that winds up, and the beam that winds up is connected with lower-cord beam by web member.

Preferably, the described beam that winds up is connected with the horizontal stiffness beam by second-hand's gunwale.

Preferably, described lower-cord beam is the folding ellbeam, one end of lower-cord beam is connected with the double flute girder steel by suspension rod, the double flute girder steel is located on two column pipes by a saddle, column pipe is located at behind the second water-cooling wall on the wall, and the other end of lower-cord beam is connected with the second rear cigarette well front wall with the 3rd pistol plate by the second end plate.

The utility model replaces with vertical truss with original folding shape vertical beam, the place is provided with header support at rear arch, and the horizontal flue bottom walls passes to water-cooling wall Hou Qiang and rear cigarette well front wall by vertical truss with load, so that the horizontal flue bottom walls better is supported, sound construction, applied widely.
