Embodiment Construction

[0025] Such as figure 1 shown, combined with figure 2 As shown, in this embodiment, the above-built general group: 65200X7000X11800mm is taken as an example for illustration. The upper-built general group is composed of 13 segments. Two gantry cranes are used for lifting. The integral hoisting method of thin-plate multi-layer superstructures of the present invention is mainly applicable to the integral hoisting of thin-plate multi-layer superstructures of large ships.

[0026] to combine Figure 3-6 As shown, the overall hoisting method of thin-plate multi-layer upper construction of the present invention comprises the following steps:

[0027] According to the on-site crane and the parameter data of the general group, check the layout position of the general group's hoisting points, lifting load and lifting margin,

[0028] Segment the general group of the superstructure, and carry out a more detailed calculation of the center of gravity of all the subsections, iron outf...

Abstract

The invention discloses a thin plate multilayer upper building integral hoisting method. The thin plate multilayer upper building integral hoisting method includes the following steps: checking hoisting point positions, the hoisting load, and the hoisting margin, segmenting an upper building total combination structure, performing weight and gravity center calculation on the segmentations, iron outfitting members and pre-buried devices, performing local reinforcement on hoisting rings and large openings, performing precision measurement and recording on all transverse bulkheads of the total section, the length, the width and the height of the total section with a central rib line of the total section as a reference line in the length direction; assigning a longitudinal and transverse bulkhead structural line with the ship central line and the central rib line as references in the length direction of the total combination structure in a deck surface where the total combination structureis located, comparing the previous total section bulkhead precision measurement data value, considering the corresponding condition of an upper structure and a lower structure of the deck 1, hoistingthe total combination structure, and performing spot welding fixing. The objective of the invention is to provide a thin plate multilayer upper building integral hoisting method which can shorten theberth period, can save reinforcing materials and human resources, and can effectively improve the production efficiency.

Description

technical field [0001] The invention relates to the field of ship building, in particular to the field of overall hoisting of multi-layer superstructures of ships. Background technique [0002] In the design and construction of modern large-scale ships, after the superstructure is manufactured in sections, the traditional method is to hoist a single superstructure section on the berth, or combine two superstructure sections together for hoisting and loading on the berth. Carrying a series of heavy tasks such as a large number of high-altitude operations and large joint correction and surgery will obviously waste manpower and time for a labor-intensive industry such as shipbuilding. [0003] At the same time, in order to reduce the deformation of the superstructure section during the hoisting process, channel steel will be used for effective reinforcement at the lower opening and inside of the superstructure section, and the reinforcing material must be removed after the hois...
