Description

Technical Field

[0001] The present application relates to the technical field of shipbuilding, and in particular to a method for constructing and transporting thin-plate sections of ships. Background Art

[0002] Ship thin plate block technology refers to the manufacturing process of splicing multiple thin steel plates into a large integral structure section according to design requirements during ship construction. Thin plate block technology can improve ship construction efficiency, reduce costs, and improve hull performance.

[0003] For large ships (such as large cruise ships), the number of thin plate sections reaches dozens, and the integrity construction work involves a large amount of thin plate welding, leveling, outfitting, painting, insulation, interior decoration, etc., and the construction period reaches more than 70-90 days. Therefore, the ship thin plate sections require a larger assembly site and a huge amount of crane resources. Due to the limited assembly site in the dock area and the shortage of crane resources, a part of the thin plate sections are usually selected to be built off-site within the range of the gantry crane in the non-dock crane area, and then large-sized transport brackets are used with large-scale transportation equipment to transport the completed thin plate sections back to the dock crane area to ensure that the construction period of the thin plate sections matches the dock loading period, so as to achieve the thin plate section loading construction node.

[0004] However, the above-mentioned off-site construction method of thin plate segments requires the simultaneous construction of several thin plate segments, and each segment requires a large-sized transport bracket.

Among them, each midship longitudinal beam 11 has a first supporting structure 21 and a second supporting structure 22 corresponding to it. As shown in FIG. Figure 1 , Figure 2 and Figure 4 As shown, the figure shows an example in which the ship thin plate section 1 has two rows of mid-ship longitudinal beams, but it is not limited to this, and the number of mid-ship longitudinal beams can also be 4 rows, 8 rows, etc.
