Container ship torsion box subsection construction method and container ship

Abstract

The invention provides a container ship torsion box section construction method and a container ship. The container ship torsion box section construction method comprises the steps that a first task group and a second task group are established respectively; and regulating the progress of the task group in real time according to the construction progress. Determining a connecting surface of the main deck middle assemblage and the hatch coaming middle assemblage as a first mounting base surface, and overturning the main deck middle assemblage to be in a normal state; and the hatch coaming middle assemblage is installed on the first installation base face of the main deck middle assemblage. And the second outer longitudinal wall middle assemblage is assembled with a large assemblage jig frame, and the main deck middle assemblage and the second outer longitudinal wall middle assemblage are folded on the basis of the second outer longitudinal wall middle assemblage. And the second inner longitudinal wall middle assemblage is folded on the basis of the second outer longitudinal wall middle assemblage, and construction of the torsion box segments is completed. On the basis that the ship building efficiency is improved, the main deck middle assemblage is kept in a normal state for hatch coaming middle assemblage installation, the hatch coaming middle assemblage installation is not limited by the width of the main deck, positioning installation and welding are more convenient, and the construction difficulty and the safety risk are reduced.

Description

technical field [0001] The present application relates to the technical field of ship construction, and in particular, to a method for constructing a segmented torsion box of a container ship and a container ship. Background technique [0002] In the process of container ship construction, it is necessary to construct the torsion box segment first. After the construction of the torsion box is completed, the torsion box is arranged above the port and starboard sides of the container ship. [0003] The torsion box segment mainly includes the inner longitudinal wall plate frame, the outer longitudinal wall plate frame and the main deck. In order to increase the cargo capacity of the container ship and facilitate the loading of containers, the main deck is set to a large opening. Compared with traditional bulk carriers, setting the main deck to a large opening will affect the strength of the whole ship, and will produce obvious stress concentration at the corners of the deck o...

AI Technical Summary

Problems solved by technology

[0005]Usually, the width of the main deck is not less than 3m. In the prior art, the assembly in the inner longitudinal wall needs to be hoisted to At the predetermined height position, high-altitude installation and high-altitude welding operations will be carried out, so there will be problems such as difficult installation and high difficulty in hatch coaming positioning, resulting in the situation that the hatch coaming cannot be fully installed, it is necessary to re-select the section of the torsion box Installation phase, thereby affecting the ship construction schedule

In addition, overhead welding and other operations are required when welding the hatch coaming, and there are potential safety hazards in the operation process, which increases the probability of safety accidents during the construction of the torsion box section
