According to the ship main force-bearing landing pad structure and the assembling and welding method, in the aspect of structural design, the whole bottom plate is optimized, the thickening cushion blocks are arranged and are in butt welding with the bottom plate, the transverse rib plates are reinforced so as to ensure the structural strength, and if structural deformation occurs in projects such as later-stage construction and grade repair, the structural deformation can be prevented; the overall levelness requirement can be met in a base plate machining mode. In the aspect of process design, the technical scheme of main hull outer plate segmentation division at the landing pad and landing pad manufacturing and installation is optimized, the important structure is installed in advance to the block construction stage, the block structure integrity is improved, and the slipway construction period is shortened. The method is reasonable in overall process, proper in manufacturing method and sequence selection, proper in assembly method and sequence, easy to operate and convenient to master, meets the technical and precision requirements of assembly and welding of the main bearing landing pad structure, and can be widely applied to manufacturing of similar structures of related ships and assembly and welding of real ships.

    本发明提供一种船舶主承力着陆垫结构及装焊方法,在结构设计方面,将底板整板优化设置若干加厚垫块并与底板对接焊,对横向肋板进行加强以保证结构强度,后期建造、等级修理等工程中若出现结构变形,可通过垫板加工的方式满足整体水平度要求。在工艺设计方面,优化了着陆垫处的主船体外板分段划分以及着陆垫制造安装技术方案,将这一重要结构提前至总段建造阶段安装,提升了总段结构完整性,减少了船台建造周期。本发明总体流程合理,制作方法、顺序选择恰当,装配方法和顺序得当,易于操作,便于掌握,满足了主承力着陆垫结构装焊的技术及精度要求,能够广泛运用到相关船舶相似结构的制造及实船装焊。
