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.
本发明公开了一种船舶大跨度甲板分段的建造方法,包括以下步骤:S1,勘划胎架地线,S2,大跨度甲板分段胎架制造,S3,甲板铺板焊接,S4,划构架线,S5,甲板纵向构件装配和焊接,S6,甲板横向构件装配焊接,S7,分段吊运上门架,S8,火工矫正变形。本发明采用了一高精度的拼板胎架,将分段的加强与胎架的设计进行了有机的结合,有效的保证了拼板的精度,减少了胎架材料的消耗,保证了分段在脱胎以后的刚度,减少了大跨度甲板的变形,有效的保证了甲板板的拼板精度;在甲板纵骨和甲板横梁的装焊过程中提供了一种科学的装配与焊接工艺,有效地减少了大跨度甲板板架结构的焊接变形。
