Process for hoisting whole assembly section of upper-layer building living zone of ship

Abstract

The invention relates to a process for hoisting a whole assembly section of an upper-layer building living zone of a ship. The hoisting process comprises the steps that the living assembly section is hoisted and assembled into a whole in a segmented mode, the whole assembly section of the living zone is then hoisted through a hoisting tool, and the peripheral wall of the whole assembly section of the living zone coincide with deck positioning piles when the whole assembly section of the living zone is 0.8-1.2 m away from the surface of a deck, the whole assembly section of the living zone is slowly put down, and finally tiny adjustment is performed through pull members on the periphery of the whole assembly section of the living zone for alignment and positioning. The process for hoisting the whole assembly section of the upper-layer construction living zone of the ship has the advantages that the whole assembly section of the living zone is firstly assembled in the segmented mode and then is wholly hoisted to the deck, accordingly the working efficiency of hoisting can be improved, a ship construction period can be shortened, the deformation of an upper-layer building in the hoisting process is prevented by adopting various structural strengthening measures, and the actual deformation amount of the upper-layer building of the ship can be minimum.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a process for hoisting a general section of a living area of ​​a ship superstructure. Background technique [0002] The integral hoisting of ship superstructure is an advanced technology in shipbuilding. With the improvement of the pre-outfitting level before the superstructure hoisting, the overall hoisting will undoubtedly expand the operation range of the superstructure on land before installation on the ship and improve labor production efficiency. , to shorten the ship construction cycle and reduce shipbuilding costs. However, due to the limitation of the shipyard equipment, site and hoisting design level, it is still limited to the range of small scale and strong superstructure rigidity; and the large-scale ships and the improvement of pre-outfitting level make the size and weight of the overall superstructure section more and more complicated. As the thickness increases, the r...

However, due to the limitation of the shipyard equipment, site and hoisting design level, it is still limited to the range of small scale and strong superstructure rigidity; and the large-scale ships and the improvement of pre-outfitting level make the size and weight of the overall superstructure section more and more complicated. As the thickness increases, the rigidity decreases relatively. At the same time, the thickness of the superstructure is also developing towards thinner plates.
