The invention relates to the technical field of ship construction, in particular to a roll-on-roll-off ship broadside segmented construction method, which is characterized in that thickening plates are arranged at ports at the bow end and the stern end of a deck, and when the thickening plates are welded, the thickening plates at the two ends can release welding stress, so that the welding deformation quantity of the deck is reduced, and the coplanarity of the deck is better. In addition, reinforcing steel channels are welded to the large opening in the deck and the position of the thickening plate in the bow and stern direction of the deck, the strength of the deck is improved, the longitudinal and transverse components and the structural face of the thickening plate are welded after the reinforcing steel channels are welded, the welding shrinkage amount in the welding process can be reduced, and then the coplanarity of the deck is better. And meanwhile, the structural surface of the thickening plate is firstly welded, and the non-structural surface of the thickening plate is welded after the manufactured middle deck assembly is welded on the broadside outer plate, so that the strength of the deck is further improved, and the coplanarity of the deck is further improved.

    本发明涉及船舶建造的技术领域,特别是涉及一种滚装船舷侧分段建造方法,通过将加厚板设置在甲板艏艉两端的端口处,在焊接加厚板时,两端的加厚板可以对焊接应力进行释放,从而降低甲板的焊接形变量,使得甲板的同面度较好。另外,在甲板上的大开口处以及加厚板的位置处沿着甲板的艏艉方向焊接加强槽钢,增加甲板的强度,在焊接加强槽钢后再焊接纵横构件和加厚板的结构面,可以减少焊接过程的焊接收缩量,进而使得甲板的同面度更好。同时,先焊接加厚板的结构面,并在将制作完成的甲板中组立焊接在舷侧外板上之后,再完成加厚板的非结构面的焊接,使得甲板的强度进一步增加,从而使得甲板的同面度进一步提高。
