The invention discloses an automobile roll-on-roll-off ship stairway structure which comprises two transverse enclosure bulkheads, and a longitudinal enclosure bulkhead is fixedly arranged between the two transverse enclosure bulkheads. A stairway cavity used for containing a stairway is defined by the hull outer plate, the longitudinal enclosure bulkhead and the two transverse enclosure bulkheads. An anti-heeling water tank is further arranged on the inner side of the ship body outer plate; the top of the anti-heeling water tank is a water tank top plate; the stairway cavity is arranged above the anti-heeling water tank; the bottoms of the longitudinal enclosure bulkheads and the bottoms of the transverse enclosure bulkheads are fixedly connected to the upper surface of the water tank top plate; a plurality of transverse strong frames are arranged in the anti-heeling water tank; the two transverse enclosure bulkheads are respectively aligned with the two transverse strong frames; the projection of the stairway cavity on the horizontal plane does not exceed the range of the projection of the heeling prevention water tank on the horizontal plane. While the functional requirement is met, transverse deformation of the ship body structure is reduced, the fatigue performance of the ship body structure is improved, the fatigue strength of key nodes of the whole ship is improved, and the safety margin of the ship body is enhanced.

    本发明公开了一种汽车滚装船梯道结构,其包括横向围壁,横向围壁为两个,两个横向围壁之间固设有纵向围壁;船体外板、纵向围壁和两个横向围壁围成用于容纳梯道的梯道腔体;船体外板内侧还设有防横倾水舱;防横倾水舱的顶部为水舱顶板;梯道腔体设于防横倾水舱的上方;纵向围壁的底部和横向围壁的底部均固接于水舱顶板的上表面;防横倾水舱内具有若干横向强框;两个横向围壁分别和两个横向强框对齐;梯道腔体在水平面的投影不超出防横倾水舱在水平面的投影的范围。本发明在满足功能性需要的同时,减少了船体结构的横向变形,改善了船体结构的疲劳性能,提高了全船关键节点的疲劳强度,增强了船体的安全裕度。
