The invention provides a tool for large-span broadside block carrying precision control of a PCTC ship, the tool comprises a distance preserving beam, the distance preserving beam comprises a main beam and two bases, the number of the bases is two, the bases are symmetrically and fixedly connected to the broadside inner wall of the PCTC ship, and the two ends of the main beam are erected on the two bases. The tool comprises the following steps that a broadside XS block is hoisted, and the half width and horizontal data of the block are determined; the optimized distance preserving beam is hoisted on the block deck; carrying out assembling and welding construction on the broadside XS block; a deck XU block is hoisted; and the distance-preserving beam is dismantled. According to the method, the hoisting process is optimized, the hoisting operation process is optimized on the premise that the hoisting precision requirement is met, the production efficiency is improved, and the situation that due to the precision problem, large-range dislocation and separation are conducted after segmented folding, a large amount of knife opening and plate replacing are caused, and the reworking workload is increased is avoided.

    本发明提出了一种用于PCTC船大跨度舷侧总段搭载精度控制的工装,包括保距梁,保距梁包括主梁和底座,底座的数量为两个,对称地固定连接于PCTC船的舷侧内壁上,主梁的两端搭设于两个所述底座上。该工装包括以下步骤:吊装舷侧XS总段,定好总段半宽、水平数据;在总段甲板上吊装优化后的保距梁;舷侧XS总段进行装焊施工;吊装甲板XU总段;拆除保距梁。本发明优化吊装流程,在满足吊装精度要求的前提下优化吊装作业流程,提高生产效率,避免由于精度问题分段合拢后大范围错位、离空导致大量开刀、换板,增加返工工作量。
