The invention provides a roll-on-roll-off ship thin deck subsection construction method and a roll-on-roll-off ship. The method comprises the steps that multiple thin decks are obtained through cutting according to construction requirements, and the multiple thin decks are leveled; fixing the plurality of thin decks at preset positions; a plurality of thin decks are welded according to a preset sequence; the flat-bulb steel, the T-shaped profile and the thin deck are welded after being assembled; and thin deck segmented construction of the roll-on-roll-off ship is completed. And in the pre-stage, the workpiece is leveled, residual stress is eliminated, and it is ensured that low-stress construction is achieved in the segmented construction process. The welding seam quality of the thin decks is guaranteed by limiting the assembly position of each thin deck; the problems of welding deformation and the like are avoided by controlling the welding sequence and the stress release direction. Therefore, the deformation condition caused by thickness limitation of the thin plate in the building process can be reduced, the problems of deformation of the segmented thin deck caused by assembly and welding and the like are effectively solved, the construction efficiency is improved, and the ship building quality is improved.
本申请提供一种滚装船薄甲板分段的建造方法及滚装船,方法包括:根据建造需求通过切割获取多个薄甲板,并对多个薄甲板进行矫平;将多个薄甲板固定于预定位置处;按照预定顺序焊接多个薄甲板;分别将球扁钢、T型材与薄甲板装配后进行焊接;完成滚装船的薄甲板分段建造。在前置阶段进行对工件进行矫平,消除残余应力,确保分段建造过程实现低应力建造。并且通过限制每个薄甲板的装配位置,保证薄甲板的焊缝质量;通过控制焊接顺序,控制应力释放方向,避免焊接变形等问题。因此,本申请能够减少建造过程中因薄板的厚度限制导致的变形情况,有效的解决了装配、焊接引起的分段薄甲板变形等问题,提高了施工效率,提高船舶建造质量。
