The invention relates to a tail fin segmented construction method which comprises the following steps: S1, marking out a line type and a waterline of a rib on a steel plate, and assembling rib parts to form a rib frame; s2, the sheet-shaped jig frames are manufactured in a plane, longitudinal braces are installed after the sheet-shaped jig frames are erected, and the sheet-shaped jig frames are connected into a whole through the braces to form a jig frame; s3, outer plates at the position of the center line of the jig frame are laid on the jig frame, the coincidence degree of the center line on the outer plates and the center line of the jig frame is detected, then the other outer plates are laid on the jig frame in sequence, and rib position lines and framework installation lines are marked on the outer plates; s4, the rib frame, the compartment component, the longitudinal girder component and the platform component are installed according to the framework installation line in the sequence from the bow to the stern; and S5, a stern shaft tube is installed, and framework welding is conducted. According to the method, the overall assembly precision of the tail fin segments and the installation precision of the tail shaft tube are ensured from the aspects of rib frame splicing, jig frame manufacturing, outer plate laying, framework assembling and the like, the precision correction work in the overall assembly carrying stage is reduced, the construction period is shortened, and the construction efficiency is improved.

    本发明涉及一种尾鳍分段建造方法,包括:S1、在钢板上划出肋骨的线型和水线,拼装肋骨部件形成肋骨框;S2、片状胎架在平面内制作,片状胎架立起后安装纵向拉条,将片状胎架通过拉条连成一体后形成胎架;S3、将胎架中心线位置的外板铺在胎架上,检验外板上的中心线与胎架中心线的重合度,再依次将其余外板铺在胎架上,在外板上划出肋位线、构架安装线;S4、按照从艏到艉的顺序分别将肋骨框、隔舱部件、纵桁部件、平台部件依照构架安装线进行安装;S5、安装艉轴管,进行构架焊接。本发明从肋骨框拼装、胎架制作、外板铺板、构架装配等方面确保尾鳍分段总组精度和艉轴管安装精度,减少总组搭载阶段的精度修正工作,缩短建造周期,提升建造效率。
