The embodiment of the invention provides an efficient lineation method for ship curved surface segment construction. The method comprises the steps that 101, after planking welding is conducted on a positively-manufactured bottom curved surface segmented outer plate, a segmented cross datum line is determined, and the segmented cross datum line comprises a segmented center line and a rib inspection line; 102, measuring and marking out intersection points of all ribs at upper board openings on the two sides of the bottom curved surface segment and the center line of the segment by taking a rib inspection line as a reference; step 103, adjusting and aligning the corresponding intersection points marked by the sideboard upper openings on the two sides and the center line of the section by using a line casting instrument in sequence; step 104, bidirectionally and continuously casting lines on the bottom curved surface segmented outer plate by using a line casting instrument, and marking out mark points according to a preset density; and step 105, determining each rib line, and completing the assembly scribing work of the bottom curved surface subsection. The method is suitable for assembly lineation or detection of all curved surface segments or workpieces constructed by a positive or tangent jig frame, the lineation detection time can be greatly shortened, the risk of mistakes and omissions can be reduced, and the lineation efficiency and precision are improved.

    本申请实施例提供了一种船舶曲面分段建造高效划线方法。该方法包括:步骤101,正造的底部曲面分段外板铺板焊接后,确定分段十字基准线,分段十字基准线包括分段中心线和肋骨检验线;步骤102,以肋骨检验线为基准,将底部曲面分段两侧舷上口、分段中心线处各肋骨交点测量划出;步骤103,依次用投线仪调整对准两侧舷上口及分段中心线已划出的对应交点;步骤104,用投线仪双向连续投在底部曲面分段外板上的线条,根据预设密度划出标记点;步骤105,确定各肋骨线,完成底部曲面分段的装配划线工作。该方法适用于所有正造或正切胎架建造的曲面分段或工件的装配划线或检测,可大大减少检测划线时间和降低错漏的风险,提高划线的效率及精度。
