Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation examples in order to express the structural features and specific applications of the present invention more clearly, but this should not limit the protection scope of the present invention.

[0019] Such as figure 1 with figure 2 As shown, the carrying method of the side structure of the present embodiment includes the following steps:

[0020] The first step is to position the side structures. The cranes are used to position the two side structures. The two side structures are placed parallel to each other. The relative dimensions of the two side structures 1 are ensured through positioning. The location mainly refers to the front and rear end faces of the two structures 1 having the same planarity ≤ 5mm, the height synchronization ≤ 5mm, and the front and rear width spacing conforming to the tolerance requirements of the design d...

Abstract

The invention discloses a carrying method of broadside structural bodies. The carrying method comprises the following steps that firstly, the broadside structural bodies are positioned, specifically,the two broadside structural bodies are positioned firstly through a crane and arranged in a mutually-parallel mode; secondly, tools are mounted on site, specifically, the two ends of each distance preserving beam are welded to the inner side faces of the broadside structural bodies correspondingly, and the distance preserving beams and the broadside structural bodies are connected in a mutually-perpendicular mode; thirdly, allowance scribing and cutting are conducted, specifically, according to positioning numerical values of the measured broadside structural bodies and theoretical values needed by in-place mounting of the broadside structural bodies, allowance scribing is conducted on parts, needing to be cut, of the broadside structural bodies, and the allowances are cut off; and fourthly, final positioning is conducted, specifically, pull pumps are used for adjusting the front-rear positions of the broadside structural bodies, after the broadside structural bodies are adjusted in place, the positions of frames of the whole broadside structural bodies are fixed through restraint welding, and thus final positioning is completed. The overall strength of a large-opening cargo compartment is improved through the distance preserving beams, and accumulated errors in the ship body construction process are reduced.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a method for loading a side structure applied to a large-open cargo hold area. Background technique [0002] During the construction of ships, cranes, as the core construction resources, play a pivotal role. If the crane resources can be released as much as possible during the construction process, the construction efficiency can be improved. The traditional positioning method requires two cranes to hoist a hull structure. The crane is used for the first time to mark the margin line of the positioning structure, and the structure is hoisted in place after trimming the margin for the second time. [0003] The traditional hoisting method applied to the side structure of the large opening cargo hold area is prone to inward or outward tilting deformation during the construction process, especially during the welding process, such deformation is more obvious.
