Hoisting method of boardside section provided with shell plate bulwark and hatch coaming

Abstract

The invention discloses a hoisting method of a boardside section provided with a shell plate bulwark and a hatch coaming. The hoisting method specifically comprises the following steps that the innerlongitudinal wall of the boardside section is placed upwards; a main hook hoisting ring is welded on a deck platform, and an auxiliary hook hoisting ring is welded to a lower opening of a shell plate;reinforcing plates are fixed to the position between a bulwark and a deck as well as at a rabbet of the bulwark; a steel wire rope is connected to the main hook hoisting ring and the auxiliary hook hoisting ring; the boardside section is hoisted; after hoisting is ended, the steel wire rope and the reinforcing plates are removed. The hoisting method can protect a sectional structure, deformationof the sectional structure in the hoisting process is avoided, the integrity of the boardside sectional structure provided with the shell plate bulwark and the hatch coaming can be ensured, the production efficiency is improved, and the repair work of the section is reduced. Meanwhile, when the section is turned over, the positions of a main hook and an auxiliary hook do not need to be replaced, and it can be ensured that the section can be hoisted in place once.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a hoisting method for side sections with outer plate bulwarks and hatch coamings. Background technique [0002] In order to increase the integrity of the side section construction, the shell bulwarks and hatch enclosures are usually built together in the section construction stage, so as to improve the construction efficiency of the ship. However, due to the protruding structure of the inner longitudinal wall and outer plate of the side section deck area with outer plate bulwarks and hatch coamings, traditional hoisting methods cannot be used to hoist this type of section, and the hoisting process is very difficult, and the hoisting During the process, damage to the segmented structure may occur. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and design a hoisting method for the side sections with o...
