[0002] In today's ship design, the design of double bottom structure is relatively common, and the overall flatness of the inner bottom surface directly affects the follow-up loading benchmark and the use function of the ship during the segmental construction of the double bottom. The control of the flatness of the bottom surface is a key point in the construction accuracy control of the double bottom section, but due to the structural characteristics of the double bottom section and the thermal deformation during the welding process, it is difficult to control the flatness of the inner bottom surface during the assembly process

The invention relates to the technical field of ship construction, and discloses a ship double-layer bottom subsection construction method which mainly comprises the following steps: drawing pile distribution lines, subsection center lines and end side lines; marking the first subarea line and the second subarea line so as to divide each pile column into an undeformed area, a first reversible deformation area and a second reversible deformation area; measuring a first width of the first reversible deformation area and a second width of the second reversible deformation area; obtaining the supporting height of each pile in the first reversible deformation area and the second reversible deformation area; and aligning and placing the inner bottom plate and the outer plate on the piles, and assembling the ship double-layer bottom. Compared with the prior art, reverse deformation can be conducted on similar segmented structures according to a certain proportion, universality is high, the supporting height of the corresponding pile column is adjusted in different reverse deformation areas, the pile column is made to meet the deformation rule in the assembling and welding process, and theplaneness of the inner bottom face of the double-layer bottom is controlled in the assembling process.
Description
technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a segmented construction method for a ship's double bottom. Background technique [0002] In today's ship design, the design of double bottom structure is relatively common, and the overall flatness of the inner bottom surface directly affects the follow-up loading benchmark and the use function of the ship during the segmental construction of the double bottom. The control of the flatness of the bottom surface is a key point in the construction accuracy control of the double bottom section, but due to the structural characteristics of the double bottom section and the thermal deformation during the welding process, it is difficult to control the flatness of the inner bottom surface during the assembly process . Contents of the invention [0003] The technical problem to be solved by the present invention is: how to realize the flatness control of the inner bottom surface...
