The invention relates to the technical field of ship construction, in particular to a construction method of a bulwark strake. The construction method of the bulwark strake comprises the steps that S1, in the ship block construction stage, round steel is divided into a middle welding area and slow welding areas at the two ends in the axial direction of the round steel, the welding areas of the round steel are symmetrically welded to the position over the bulwark strake, and a non-penetration welding area is formed between the round steel and the upper end face of the bulwark strake; s2, when ship broadside sections are assembled or closed, each top strake butt joint is welded; s3, round steel is mounted above each butt joint of the bulwark strake, round steel butt joints are formed by the two ends of the round steel crossing the butt joints of the bulwark strake and the ends of the slow welding areas of the round steel on the corresponding sides, and each round steel butt joint is welded; and S4, the slow welding area of the round steel and the round steel crossing the butt joint of the bulwark strake are symmetrically welded to the position over the bulwark strake. And the top strake is welded with the round steel, and a non-penetration area is formed between the top strake and the round steel, so that the crack resistance and the crack arrest performance of the top strake are improved.

    本发明涉及船舶建造技术领域,尤其涉及一种舷顶列板的建造方法。舷顶列板的建造方法包括步骤S1:在船舶分段建造阶段,将圆钢沿其轴向划分为中间的焊接区和两端的缓焊区,圆钢的焊接区对称焊接于舷顶列板的正上方,并在圆钢与舷顶列板的上端面之间形成非焊透区域;S2:在船舶舷侧分段总组或合拢时,焊接每个舷顶列板对接缝;S3:在每个舷顶列板对接缝的上方均安装圆钢,跨舷顶列板对接缝的圆钢的两端分别与对应侧的圆钢的缓焊区的端部形成圆钢对接缝,焊接每个圆钢对接缝;S4:圆钢的缓焊区与跨舷顶列板对接缝的圆钢均对称焊接于舷顶列板的正上方。舷顶列板焊接有圆钢且两者之间形成有非焊透区域,提高了舷顶列板的抗裂性能和止裂性能。
