Embodiment Construction
[0019] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0020] The overall hoisting process of the ship superstructure of the present invention comprises the following steps:
[0021] A. The superstructure 1 is assembled near the wharf. At the same time, the internal and external structure of the superstructure 1 is strengthened, and the margin is cut according to the actual situation before hoisting, and there is no margin to board the ship;
[0022] B. Install positioning eye rings at the lower openings of the front and rear end wall corners of the assembled superstructure 1. There are three positioning eye rings, two in front and one in back or two in back and one in front;
[0023] C. Mark and assemble the outline of the bottom layer of the superstructure 1 on the deck of the berth, and install and weld positioning pins at the corresponding corners of the front and rear end walls;
[0024] D....

The invention discloses an integral hoisting technology of an upper layer building of a ship. The technology comprises the steps that the interior and the exterior of the upper layer building are structurally reinforced; locating eye rings are mounted on corner lower openings of the front end wall and the rear end wall of the upper layer building; the outline of a bottom layer of the upper building is assigned and assembled on the deck of a shipway, locating pins are corresponding corner positions of the front end wall and the rear end wall, and welding is carried out; the deck plane and the trunk bulkhead of the upper building of the ship are structurally reinforced; according to designed lifting points, the upper layer building is lifted, and is placed on the corresponding position of the deck of the shipway; and the upper layer building is fixed, welding is completed, and whole mounting is achieved. The advance fitting-out rate of the area of the upper layer building can be improved, the ship construction period is shortened, and through various structural reinforcing measures, the upper building is prevented from deforming in the lifting process; and according to reinforcement measures, beside dismounting, the upper layer building can be used as a reinforcing component of the ship finally to be reserved.
Description
technical field [0001] The invention relates to an integral hoisting process 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 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 ship and the improvement of pre-outfitting level make the size and weight of the superstructure segment more and more serious. As the thickness increases, the rigidity decreases relatively. At the same time, the thickness of the superstructure is also ...
