Background
The superstructure of the ship (referred to as 'upper building') is a living residential area of a crew, and the flatness and the integral aesthetic appearance of the upper building sectional surrounding wall and the deck are particularly important. The ship is built because the plate is thinner, the structure is less, the size of the segment is larger, and the deformation is easy to generate through the assembly, welding and transfer of four stages of blanking, plate splicing, segmentation and folding. The existing upper building method generally adopts a sectional building method, namely, an upper deck, deck stringers, crossbeams, trunk walls and other components are built in a workshop to form a section, then four sections are assembled on a shipway, the method inevitably needs to carry out sectional transportation and hoisting, the upper building structure is very fragile, the trunk walls and the decks lack enough strength, and deformation is easily generated in the hoisting process. If a sectional construction mode is adopted, a large number of temporary reinforcing measures must be additionally added on the sections, the reinforcing has enough specifications to ensure the strength and form a complete frame structure to ensure the rigidity of lifting and turning, the workload is greatly increased, and the waste and the consumption of auxiliary materials are extremely high.
In addition, a building method of the shipway in bulk can be adopted, namely all structures such as the trunk walls, the deck stringers, the deck strong beams, the deck beams, the brackets and the like are blanked and then directly spliced and welded on the shipway; because the working surface of the slipway is narrow, the building work is difficult to spread, and the building efficiency is low; the arrangement usually depends on a large-scale crane, so that the number is limited, and the hoisting requirement of large-area bulk construction is difficult to meet; the structural deformation is not easy to control.
