The invention discloses a ship engine room segmented construction method in the technical field of ship segmented construction. The ship engine room segmented construction method comprises the steps that S1, rib molded line positions and plate seam line positions in engine room segmented three views are determined; s2, dividing the cabin into an upper part section and a lower part section along a plate sewing line section; s3, determining rib structures of the upper section and the lower section; s4, building of the upper section and the lower section is completed; and S5, the upper segment serves as a reference segment, the lower segment serves as a hoisting segment, and building of the cabin segment is completed. According to the method, an inverse overall construction mode of the cabin section is sectioned into a two-layer inverse middle assembly large construction mode, and the upper section and the lower section are assembled and folded into the cabin section in the large assembly, so that the three-dimensional operation height, the hoisting difficulty and the construction process difficulty of the cabin section are reduced, the production efficiency is also improved, and the production cost is reduced. The operation period of the jig frame is shortened, and control over the precision size in the building process is facilitated.

    本发明公开了船舶分段建造技术领域的一种船舶机舱分段建造方法,包括:步骤S1,确定机舱分段三视图中肋骨型线位置和板缝线位置;步骤S2,沿板缝线将机舱分段划分为上部分段和下部分段;步骤S3,确定上部分段和下部分段的肋骨结构;步骤S4,完成上部分段和下部分段的建造;步骤S5,以上部分段为基准分段,下部分段为吊装分段,完成机舱分段的建造。本申请将机舱分段的反态整体建造方式剖切为两层反态中组立做大建造方式,并在大组立实现上部分段和下部分段总装合拢为机舱分段,不仅降低了机舱分段的立体作业高度、吊装难度和建造工艺难度,还提高了生产效率,缩短了胎架运转周期,有利于建造进程中精度尺寸的控制。
