Method for half-breadth double-span total assembling and building in shipbuilding

Abstract

The invention relates to a method for half-breadth double-span total assembling and building in shipbuilding, which comprises the following steps: firstly, dividing the half-breadth building at the bottom of a cargo area of a ship into four sections including two double-layer bottom sections and two bottom edge water camber sections; secondly, using one of the double-layer bottom sections as a reference, performing normal total assembling on the two double-layer bottom sections; and thirdly, aligning and welding the two bottom edge water camber sections with the corresponding double-layer bottom sections first, and then performing butt welding on the two adjacent bottom edge water camber sections so as to form a half-breadth type total section. The building method is advantageous for the structural completeness of a shipway, and can speed up the structural submission progress. The pitch point control at a bilge round-turning part can be performed at the total assembling in advance, thus the number of butt joints at the round-turning part of an upper shipway is reduced, the shipway and a total assembling platform are used reasonably, and the utilization rate of the total assemblingplatform is improved.

Description

technical field [0001] The invention relates to shipbuilding, in particular to a new method for carrying the general group of sections at the bottom of the cargo hold area during the shipbuilding process. Background technique [0002] The current structural form of the bottom section of the cargo hold area of ​​​​bulk ships is mainly a longitudinal frame structure. Generally speaking, this type of structure has more longitudinal members than transverse members, and the longitudinal arrangement of longitudinals and girders in the hull is denser than the transverse arrangement of ribs and ribs in the hull. The arrangement of the ballast tanks in the bottom area of ​​the ship is characterized by separate arrangements on both sides of the starboard and starboard sides, and the two ballast tanks on the left and right sides are not connected to the tank structure. For the butt joint of the bottom section of the hull cargo hold area, the heavy workload is the butt welding work of ...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of this technology is that the workload of the cross-section joints is relatively large, which is not conducive to the structural integrity of the cabin, and the structural submission progress of the bottom section ballast tank is affected by the heavy workload of the section end face, thus affecting the construction period of the berth
