Quick positioning and mounting method for double I-shaped beams on cabin section of container ship

Abstract

The invention discloses a method for quickly positioning and installing double I-shaped beams on a cabin section of a container ship. The method comprises the following steps: checking and constructing the squareness of a main deck in a cabin section plate splicing stage; drawing the center line of the position of the longitudinal girder in the assembling process and rebounding the center line to a non-component surface; strictly constructing a 150M. K datum line at the bow part position, and ensuring that a right angle is formed between the bow part datum line and the center line; checking the accuracy of I-beam incoming goods; and after the segmented components are installed, the installation position, size and precision of the I-shaped beam are positioned at a time through a total station. According to the method disclosed by the invention, the I-shaped beam is quickly positioned and mounted in the segmented assembly stage, so that the defects of low precision and repeated correction are avoided, the production cycle of a ship is shortened, and the precision of the I-shaped beam is improved.

Description

technical field [0001] The invention relates to ship building, in particular to a method for positioning and installing duplex girders on cabin segments during container ship building. Background technique [0002] At present, a single I-beam on the engine room section of a small container ship can be controlled and inspected using conventional inspection tools such as a tape measure, a wire hammer, and a level. However, as the container ships become larger and larger, the precision requirements for the installation of I-beams are getting higher and higher, and conventional precision inspection tools are no longer suitable for the installation of I-beams. [0003] For large-scale containers, there are two I-beams on the section of the engine room. During the construction, the synchronization, distance, end face and installation accuracy of the two I-beams are extremely high. If it cannot be installed quickly, If the accuracy reaches the standard at one time, there will be g...

Problems solved by technology

[0003] For large-scale containers, there are two I-beams on the section of the engine room. During the construction, the synchronization, distance, end face and installation accuracy of the two I-beams are extremely high. If it cannot be installed quickly, If the accuracy reaches the standard at one time, there will be great constraints on the segmented construction cycle

Moreover, if the installation of the I-beam fails to meet the standard at one time, the difficulty of correction and the waste of labor will be extremely serious.
