Embodiment Construction

[0040] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0041] Such as Figure 1 to Figure 8 As shown, a kind of ultra-large container ship hatch enclosure and torsion box integrated construction method of the present invention comprises the following steps:

[0042] S1: Build hatch coaming assembly 1, deck assembly 2, inner shell assembly 3 and outer shell assembly 4 respectively;

[0043] The process of constructing the hatch coaming assembly 1 is as follows:

[0044] Step 1: Place the hatch coaming web 11 horizontally on the ground, weld multiple first hatch coaming ribs 13 vertically to the hatch coaming web 11, and then lift the hatch coaming side vertical plate 12 by magnetic force Horizontally placed on the first rib 13 of the hatch coaming and welded; this step forms the first assembly of the hatch coaming;

[0045] Step 2: place the hatch coaming top plate 14 horizontally on the gro...

Abstract

The invention discloses an ultra-large container ship hatch coaming and torsion box integrated construction method, which is applied to the field of ship construction and mainly comprises the following steps: S1, respectively constructing a hatch coaming assembly, a deck assembly, an inner shell plate assembly and an outer plate assembly; S2, the hatch coaming assemblage and the deck assemblage are spliced and then welded to form a hatch coaming deck assembly; S3, the hatch coaming deck assembly, the inner shell plate assemblage and the outer plate assemblage are spliced and welded; the integrated construction efficiency of the hatch coaming and the torsion box can be greatly improved.

Description

technical field [0001] The invention relates to the field of shipbuilding, and more specifically relates to an integrated construction method of a hatch enclosure and a torsion box of an ultra-large container ship. Background technique [0002] The 20000TEU is the same as other container ships. It is an open ship. The deck and hatch coaming bear the maximum load. High-strength thick plates are used to meet the structural strength. Yield strength on top of box ship. EH40 BCA crack arrest steel is used for the deck area and EH47 BCACOD crack arrest steel is used for the hatch coaming. [0003] The so-called crack arrest steel is the steel that has the ability to prevent cracks from expanding at a high speed. Special requirements are added during the construction process: firstly, avoid any temporary component welding work on EH47 crack arrest steel; if the welding of temporary components cannot be avoided, when the temporary component is cut off, the root with a height of 5m...
