The invention provides a method for constructing a stern section without a stern tube sleeve, side construction is performed by taking the left side of the section as a base plane, and the method comprises the following steps: S1, constructing a curved surface jig frame, laying a larboard outer plate, and finishing the upper jig positioning of a stern steel casting; s2, the platforms and the lower rib plates, the left rib plates and the upper rib plates in the rib plates are installed; s3, the bow steel casting is hoisted; s4, pulling a steel wire rope as a shaft hole center line of the stern section; s5, by taking the steel wire rope as a reference, adjusting the relative position of the bow steel casting and the stern steel casting, and completing welding; s6, installing and welding the right middle rib plates and the sternpost middle keel; s8, welding is conducted after segmented overturning; according to the method, a traditional vertical-state building mode is changed into a lateral-state building mode, so that the defect that in the vertical state, due to the fact that no stern pipe sleeve is arranged below the stern steel casting for supporting, segmented deformation and collapse are extremely likely to be caused is overcome, the segmented building precision is improved, the high-altitude operation amount in the segmented building process is reduced, and the operation safety is improved.
本发明提供一种无艉管套艉部分段的搭建方法,其以分段左侧为基面进行侧造,该搭建方法包括:S1、搭建曲面胎架,铺设左舷外板,并完成艉部铸钢件的上胎定位;S2、安装各平台及各肋板中的下部肋板、左侧肋板和上部肋板;S3,吊装艏部铸钢件;S4、拉钢丝绳作为艉部分段的轴孔中心线;S5、以钢丝绳为基准,调整艏部铸钢件与艉部铸钢件的相对位置,并完成焊接;S6、安装焊接各右中肋板和艉柱中龙筋;S8、分段翻身后焊接;本发明将传统立态建造模式修改为侧态建造模式,以克服立态状态下,艉部铸钢件因下方无艉管套支撑,极易导致分段变形和坍塌的不足,提高分段建造精度,并减少分段建造过程中的高空作业量,提高作业安全性。
