[0002] In the prior art, a car carrier, abbreviated as a car transport ship, refers to a specialized ro-ro ship dedicated to transporting cars (cars, trucks, and heavy vehicles), and generally consists of multiple vehicle decks.
[0003] Due to the large molded depth of the car carrier, in order to prevent the center of gravity from being too high and affecting the stability of the ship, generally only small cars with relatively small weights are loaded on the upper deck. The thickness of the deck steel is relatively thin, generally about 6 mm, and the deck area is large, the transverse span is large, and the center of gravity is high. Therefore, the precision control of the deck and the stability control of the ship are very critical during construction. In the prior art, after cutting and welding the steel thin deck, due to the thickness limitation of the thin deck, problems such as serious deformation of the thin deck will occur during the welding process. Subsequently, a large amount of time is required for thermal straightening by fire, or even the severely deformed area needs to be removed and reassembled and welded again, resulting in a large amount of on-site construction work and many on-site reworks. More seriously, it may cause problems such as the scrapping of sections, increasing the material and labor costs during the shipbuilding process and affecting the shipbuilding cycle.
