Embodiment Construction
[0010] A construction method for medium and small sections in shipbuilding, comprising the following steps: the manufacture of three-dimensional sections can be combined into a whole by combining two sections or more than two sections according to the section division diagram, combined with the construction site and lifting capacity construction, but the large joints are only tacked and not welded, and then disassembled and closed on the gondola to control the smoothness of the shell plate at the joint of the sections; strive to achieve the goal of precision shipbuilding and improve the manufacturing quality of the closed sections without margin. The closed section of the berth without margin must be assembled, welded and corrected in the three-dimensional section, and submitted for inspection and approval, and then the sub-section allowance is carried out for the second scribing and groove cutting to provide high-quality sections for the close-up of the slipway; pay close atten...

The invention discloses a section construction method for medium and small sections in shipbuilding. The method comprises the steps as follows: three-dimensional sections are manufactured on the basis of a block division diagram and in combination of the construction sites and hoisting capacity, two or more sections can be combined and wholly built, a large seam is just subjected to positioning welding but is not welded, and then a shipway is dismounted and lifted for folding, so that smooth shell plate lines at the section joints are controlled; the target of precise shipbuilding is realized with efforts, and the manufacturing quality of non-allowance folding sections is improved; measurement record of main dimensions of sections are performed seriously after planar sections and three-dimensional sections are completed, and measurement data is submitted for shipway for hull erection; and before section folding, cabinets, large bases, mechanical equipment, pipelines and the like enter the cabin in advance, welding positioning is performed on the machinery capable of being in place, and machinery which is difficult to be in place is subjected to temporary firm positioning. The method is simple and convenient, easy to operate and good in working effect.
Description
technical field [0001] The invention relates to a ship manufacturing method. Background technique [0002] The construction methods of the middle and small sections in the existing shipbuilding are complex and the working effect is not ideal. Contents of the invention [0003] The object of the present invention is to provide a kind of simple and effective middle and small segmental construction method in ship building. [0004] Technical solution of the present invention is: [0005] A construction method for medium and small sections in shipbuilding, which is characterized in that it includes the following steps: the manufacture of three-dimensional sections can be divided into two sections or more than two sections according to the section division diagram, combined with the construction site and lifting capacity Segments are combined for overall construction, but the large joints are only tacked and not welded, and then disassembled and closed on the gondola to contr...
