Segmented construction method for troughed bulkhead

Abstract

The invention discloses a segmented construction method for a troughed bulkhead. The segmented construction method comprises the following steps that S100, according to the ship design requirements, prefabricated steel plates are bent and pressed into Z-shaped bulkhead assemblies; S200, the multiple Z-shaped bulkhead assemblies are assembled and welded into the troughed bulkhead on a jig frame; S300, wall pier assemblies are assembled and formed; S400, the troughed bulkhead and the wall pier assemblies are assembled and formed; S500, anti-accumulating plates are mounted between the troughed bulkhead and the wall pier assemblies; and S600, connecting welding seams between the anti-accumulating plates and the troughed bulkhead as well as between the anti-accumulating plates and the wall pierassemblies are subjected to air tightness inspection. The troughed bulkhead of a ship is split into the multiple Z-shaped bulkhead assemblies for separate machining, then the Z-shaped bulkhead assemblies are assembled and welded into the complete troughed bulkhead on the jig frame, mounting of the anti-accumulating plates is advanced at the construction stage of the troughed bulkhead, thus the using rate of the jig frame of the troughed bulkhead can be increased, the construction efficiency can be improved, and meanwhile, the problem that continuity and safety of operation cannot be ensured due to the narrow and small construction space caused by mounting in the final assembly stage of the ship is solved.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a segmented construction method of a ship trough bulkhead. Background technique [0002] At present, in the process of hull construction, due to the design and ship type requirements of some ships (such as bulk carriers and oil tankers), the subdivision bulkheads of cargo holds need to be designed as grooves. [0003] The existing manufacturing method of trough-shaped bulkheads is as follows: at the cross intersection position of the transverse bulkhead and the longitudinal bulkhead of the ship, a large joint is symmetrically arranged at a certain distance (1180mm) from the transverse bulkhead to the longitudinal bulkhead, and then the disconnected The rear cross transverse bulkheads are divided into longitudinal bulkheads. Before splicing, the cross transverse bulkhead needs to be made into advanced components in advance, and the position of the cross transverse bulkhead ...

AI Technical Summary

Problems solved by technology

Before splicing, the cross transverse bulkhead needs to be made into advanced components in advance, and the position of the cross transverse bulkhead needs to be vacated in advance when the upper frame of the channel bulkhead is welded, and the lower wall pier needs to be divided into smaller parts , which makes it difficult to control the precision of component manufacturing and segmented large groups

In addition, the installation space of the anti-build-up plate in the section of the corrugated bulkhead is narrow, and the construction procedures such as assembly, welding, tightness test, sand blasting, and painting are difficult to construct

The site is sluggish and the utilization rate is not high, the production cycle of the ship's grooved bulkhead is long, the quality control is difficult, and the economy is not good
