The invention relates to a double-sided preassembling method for a bulkhead guide rail on a large container ship. The bulkhead is a non-watertight bulkhead, the bulkhead is of a hollowed-out frame structure, and the installation precision of the bulkhead guide rail installed on the two faces is smaller than 7 mm. The method comprises the following steps: firstly, mounting a guide rail bracket on a horizontal jig frame of a compartment of the container ship; measuring levelness at a bay rib position datum line by taking one surface on which the guide rail bracket is mounted as a rear wall, and marking each hard gear of the bay by a punching point; then, the bay is adjusted to be horizontal again after the bay is turned over, the levelness of the guide rail frame located on the rear wall after installation is ensured, and the reference rib position line, the rear wall guide rail frame and the front wall guide rail frame to be installed are parallel to one another; therefore, the installation reference is determined, and the double-sided guide rail bracket is positioned and preassembled according to the found installation reference. The method is easy to operate, wherein guide rail preassembling can be completed in advance, the total assembling stage time is shortened, so that the pressure of a total assembling site is relieved, the building period in a dock is shortened, and the ship building efficiency is improved.
本发明涉及一种大型集装箱船上隔舱导轨的双面预装方法,所述的隔舱为非水密隔舱,该隔舱为镂空的框架结构,双面安装的隔舱导轨安装精度小于7mm,该方法需要先将集装箱船的隔舱在水平胎架安装好一面导轨架,安装好导轨架的一面为后壁,然后在隔舱肋位基准线测量水平度,在隔舱各硬档处以洋冲点标记,隔舱在翻身后重新调节隔舱水平,确保安装后位于后壁的导轨架的水平度,使得基准肋位线、后壁导轨架和即将安装的前壁导轨架相互平行,从而确定安装基准,以找到的安装基准进行双面导轨架的定位预装。本发明方法操作简单,可以提前完成导轨预装、减少了总组阶段时间、减轻总装场地的压力,缩短了船坞内建造周期,提高了船舶建造效率。
