Problems solved by technology

[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

Embodiment Construction

[0018] The following describes the present invention in further detail with reference to the accompanying drawings and specific implementation cases, in order to express the structural features and specific applications of the present invention more clearly, but the protection scope of the present invention should not be limited by this.

[0019] Such as figure 1 with figure 2 As shown, the method for loading a side structure in this embodiment includes the following steps:

[0020] The first step is to locate the side structure. A crane is used to position the two side structures. The two side structures are placed parallel to each other. The positioning ensures the relative size of the two side structures 1. The position mainly refers to the same plane degree of the front and rear ends of the two structures 1 ≤5mm, height synchronization ≤5mm, the front and rear width spacing is consistent with the tolerance requirements of the design drawings, generally ≤6mm, the two side struc...

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 cargo hold area with a large opening. Background technique [0002] As the core construction resource, cranes played a pivotal role in the construction of ships. 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 be used for hoisting a hull structure. The crane is used for positioning the structure for the first time to draw a margin line, and the structure is hoisted in place after the margin is repaired for the second time. [0003] The traditional hoisting method applied to the side structure of the cargo hold area with large openings is prone to inward or outward tilting deformation during the construction process, especially during the welding process. Summary of the invention [0004] In view ...
