The invention provides a pre-assembly method for ship deck sections, which comprises the following steps: moving a deck section assembly forward to a manufacturing stage, and pre-assembly is performed on a jig frame of an upper deck section before the upper deck section is subjected to reverse building and tire release and after a lower deck section is subjected to tire release, so that the total land occupation is reduced; meanwhile, due to the fact that the deformation of the upper deck section is small, the allowance of the lower end face of the upper deck section can be omitted, allowance cutting is conducted when few deck sections are pre-assembled, and the assembling efficiency is improved; after the deck sections are pre-assembled, the overall strength of the structure is improved, and deformation of the deck sections in the shelving and lightering stages can be reduced.
本申请提供一种船舶甲板分段的预总组方法,将甲板分段总组前移至制造阶段,在上甲板分段反胎建造脱胎前,将下甲板分段脱胎后,于上甲板分段的胎架上做预总组,减少总场地占地;同时由于上甲板分段未脱胎分段变形较小,可以取消上甲板分段下端面的余量,使得较少甲板分段预总组时余量修割,提高总组效率;甲板分段预总组后结构整体强度提升,可减少甲板分段在搁置及驳运阶段变形。
