The invention relates to the technical field of ship construction, in particular to a deck pre-arching method. According to the deck pre-arching method, a deck comprises a plurality of segments, and the segment construction method comprises the steps of plate structure manufacturing, T beam manufacturing, plate structure and T beam assembling, segment tire separation, segment back burning and segment inspection. The deck pre-arching method comprises the following steps that in the T-beam manufacturing step, pre-arching treatment is conducted on a T-beam; in the step of assembling the plate structure and the T-beam, pre-arching treatment is conducted on the plate structure; and after the step of sectional tire separation and before the step of sectional back burning, whether the T beams meet the pre-arching requirement or not is checked, and the T beams which do not meet the pre-arching requirement are subjected to pre-arching treatment. According to the deck pre-arching method, the pre-arching process is reasonably added, collapse deformation caused by existing off-tire back burning and transportation is counteracted, the trend of facilitating middle arching is still kept after segmented turning over, extra redundant engineering does not need to be added, the labor amount is reduced, and the deck building period is shortened.
本发明涉及船舶建造技术领域,尤其涉及一种甲板预拱方法。所述甲板预拱方法甲板包括若干分段,分段建造方法包括板结构制作、T梁制作、板结构与T梁组装、分段离胎、分段背烧及分段报验;甲板预拱方法包括如下步骤:在T梁制作步骤中,对T梁进行预拱处理;在板结构与T梁组装步骤中,对板结构进行预拱处理;在分段离胎步骤之后,在分段背烧步骤之前,检验T梁是否满足预拱需求,并对不满足预拱需求的T梁进行预拱处理。该甲板预拱方法通过合理增加预拱工艺,抵消了现有的离胎背烧及运输产生的下塌变形,分段翻身后依然保持有利中拱趋势,无需增加额外冗余工程,降低劳动量,缩短甲板建造周期。
