Embodiment Construction

[0031] A method for the installation of crack arresting steel hatch coamings for ultra-large container ships of the present invention will be further described in detail below in conjunction with the accompanying drawings, in order to understand the application process of the method of the present invention more clearly, but it cannot be based on this To limit the protection scope of the present invention.

[0032] like Figure 1-6 As shown, the present embodiment is used for the installation method of the anti-crack steel hatch coaming of an ultra-large container ship, and the installation method includes the following steps:

[0033] S1. The group to which the torsion box belongs is manufactured independently, and the main board 1 is assembled, and then the main deck group 3, the longitudinal wall group 4 and the outer rib 5 are assembled and welded. When the distance between the outer rib 5 and the end of the component is > 1m , on the main deck group 3, a false compartmen...

Abstract

The invention discloses a method for mounting ultra-large container ship crack arrest steel hatch coaming. The mounting method comprises the following steps: S1, manufacturing a small assemblage which an anti-torsion box belongs to; S2, setting a moulding bed special for a main deck middle assemblage to realize component positioning; S3, assembling and welding crack arrest steel hatch coaming in the main deck middle assemblage stage and finally form an integrated hatch coaming main deck middle assemblage; S4, manufacturing an anti-torsion box longitudinal wall enlarging middle assemblage to form the anti-torsion box longitudinal wall enlarging middle assemblage with qualified precision; and S5, performing anti-torsion box segmentation supergroup, mounting outfitting pieces, such as a box column above the main deck and the like, and performing technological correction on the anti-torsion box segmentation to form the anti-torsion box segmentation. The method is favorable for improving the mounting precision of the crack arrest steel hatch, reducing damage risk of the crack arrest steel caused by burn-in and disassembling processes, bringing forward the mounting stage of the hatch coaming and creating conditions for in-advance mounting of other outfitting pieces so as to effectively shorten the construction cycle of the whole container ship.

Description

technical field [0001] The invention relates to shipbuilding, in particular to a method for installing a crack-stopping steel hatch coaming of an ultra-large container ship. Background technique [0002] At present, more and more high-strength anti-crack steel is used in the hatch coaming and main deck area of ​​container ships to reduce the light weight of the ship. The use of crack arrest steel has brought great challenges to the early installation of the hatch coaming. At present, the installation of anti-crack steel hatch coamings of ultra-large container ships is mainly carried out by the following methods: horizontal installation of crack-stop steel hatch coamings in stages, or normal installation of crack-stop steel hatch coamings in the dock stage Install. The above two installation methods have the following disadvantages: [0003] First, if the crack arresting steel hatch coaming is installed horizontally in stages, since there is a K-shaped bevel between the cra...
