The invention discloses a construction method for a middle floor height positioning datum line in ship segmented construction. The construction method specifically comprises the steps of determining the floor height net size value between two adjacent decks; determining a preset contour line value, and determining a construction value according to the floor height net size value and the preset contour line value; completing construction of the segments through inversion operation, after it is determined that the precision of the segments is qualified, transferring the construction values to the stand columns and the enclosure walls on the inverted segments, measuring the construction values vertically and upwards on the stand columns with the deck surface theoretical line of the deck where the stand columns are located as the reference, and knocking sample punching points out; measuring the construction value vertically and upwards on the enclosure wall with the deck surface theoretical line of the deck where the enclosure wall is located as the reference, knocking the sample punching points out, multiple sets of sample punching points are knocked out on the enclosure wall, and the adjacent sample punching points in each set are spaced by a first interval.

    本发明公开了一种船舶分段建造中层高定位基准线的施工方法,具体包括:确定相邻两层甲板之间的层高净尺寸值;确定预设等高线值,根据所述层高净尺寸值和所述预设等高线值确定施工值;采用倒装作业完成分段的建造,确定分段的精度合格后,在倒置的分段上将所述施工值驳至立柱和围壁上,其中,在所述立柱上以其所在甲板的甲板面理论线为基准竖直向上量出所述施工值并敲出样冲点,在所述围壁上以其所在甲板的甲板面理论线为基准竖直向上量出所述施工值并在敲出样冲点,围壁上敲出多组样冲点,且每一组中相邻的样冲点间隔第一间距。
