Problems solved by technology

[0006] Aiming at the problems existing in the prior art, the present invention provides a segmented construction method for a large-span deck of a ship. The present invention overcomes the problem that there are too many process reinforcements in the construction process of the prior art, and the surface of the parent material is easily damaged by the process of dismantling the process parts. The damage caused by the welding deformation is large, which affects the ship construction cycle

Embodiment Construction

[0045] A construction method of a large-span deck section of the present invention will be described in further detail below in conjunction with the accompanying drawings, in order to understand the application process of the method of the present invention more clearly, but the protection scope of the present invention cannot be limited with this.

[0046] Such as Figure 1 to Figure 13 As shown, the present embodiment is a segmented construction method of a large-span deck of a ship, and the manufacturing method comprises the following steps:

[0047] S1. Plan the tire frame ground wire, such as figure 1 As shown, use the laser theodolite to survey and delineate the subsection center ground line 1-1, take the subsection center ground line 1-1 as the positioning reference line along the x direction of the ship, and draw out according to the subsection center ground line 1-1 The square line is used as the positioning ground wire 1-2 without margin, and the perpendicularity er...

Abstract

The invention discloses a method for constructing a large-span deck section of a ship. The method comprises the following steps of S1, surveying and marking a jig frame ground wire; S2, manufacturinga large-span deck section jig frame; S3, welding deck bed boards; the high-precision plate splicing jig frame is adopted, segmental reinforcement and jig frame design are organically combined, the plate splicing precision is effectively guaranteed, jig frame material consumption is reduced, the rigidity of segments after jig removal is guaranteed, deformation of a large-span deck is reduced, and the plate splicing precision of deck plates is effectively guaranteed; a scientific assembling and welding process is provided in the assembling and welding process of the deck longitudinal bones and the deck cross beams, and welding deformation of the large-span deck grillage structure is effectively reduced.

Description

technical field [0001] The invention belongs to the field of ship building, in particular to a segmented construction method of a large-span deck of a ship. Background technique [0002] Long-span deck section is a special type of section in large ships, and its construction quality and construction efficiency greatly affect the ship's construction quality and construction period. At present, for conventional long-span deck segmental construction, there is no suitable tire frame auxiliary facility. During the process of deck plate assembly, deck longitudinal and deck beam assembly and welding, the construction technology is backward, the structure is deformed greatly, and the quality of ship construction is low. It brings a lot of manpower and material loss to the correction of the subsequent subsections. This construction method has the following deficiencies: [0003] First, there is a lack of effective tire frame design and construction technology in the segmental constr...
