Overall manufacture method for forecastle bulwark of ship

Abstract

The invention relates to an overall manufacture method for a forecastle bulwark of a ship. The overall manufacture method comprises following steps: 1, manufacturing of five sheet bodies by linear division based on the forecastle bulwark in the manner of bilateral symmetry; 2, manufacturing of special-purpose jig frames corresponding to line types of all sheet bodies with five jig frames in total; 3, hanging of the jig frames on a bulwark plate for planking or laminating after pass acceptance inspection of the jig frames; 4, sequential assembly and welding of a bulwark stay, a reinforcing rib and a bulwark supramarginal plate based on mounting dimensions of a framework and additional installation of reinforcing material in a proper amount; 5, independent hoisting of each bulwark sheet body for assembly and welding at the corresponding position of the ship after pass acceptance inspection of sheet bodies so that the overall manufacture of the bulwark is finished. The overall manufacture method for the forecastle bulwark of the ship has following beneficial effects: the bulwark is made in the manner from high altitude construction to grading operation so that the difficulty in manufacturing the bulwark is greatly decreased; and tandem-type construction between a conventional ship body and the bulwark is changed to be parallel construction so that the large amount of manufacture time is saved.

Description

technical field [0001] The invention relates to ship building, in particular to a method for integrally manufacturing ship forecastle bulwarks. Background technique [0002] Such as figure 1 As shown, during ship design and construction, the forecastle bulwark mainly includes bulwark plate 1, bulwark edge plate 2, bulwark bracket 3 and stiffener 4 and other structures. During the construction of ships in the prior art, for the usual manufacturing process of the forecastle bulwark, it is mainly carried out by the following methods: [0003] Install all the bulwark brackets 3 to the designated positions first; then hoist the bulwark panels 1 to the corresponding positions, and make the bulwark panels 1 and bulwark brackets 3 fit together by means of water and fire bending plates and chain hoists, and the bulwark panels The lower edge of the plate coincides with the line shape of the hull plate, and the line shape of the bulwark plate is fixed by welding; along one direction,...

AI Technical Summary

Problems solved by technology

[0005] First, due to the thinner thickness of the bulwark panels, lower height (over 1100mm) and longer length, it is easy to twist when the bulwark panels are hoisted, which will increase the follow-up workload;

[0006] Second, in the process of wrapping the bulwark panels, the bulwark panels are always outside the hull and belong to high-altitude operations, so the construction of the bulwark panels is extremely difficult;

[0007] Third, in the production process of ships, the fabrication of bulwarks and the construction of the hull belong to serial construction, which prolongs the ship construction cycle
