The invention discloses a high-precision building method for a ship gangway. The high-precision building method comprises the following steps that step 1, a gangway jig frame is manufactured; step 2, reverse deformation is set for the gangway jig frame; step 3, holing is conducted on the ship body section outer plate; step 4, a side port main board and a ship body section outer board are laid on the same tire; step 5, the ship body section outer plate is assembled and welded, the sizes of the ship body section outer plate before and after welding are measured, and the ship body section outer plate is hoisted away when the sizes of the ship body section after and before welding are within the error range; step 6, a gangway main plate is assembled and welded; step 7, a hinge is installed and concentricity measurement is carried out; step 8, a gangway positioning involution line is manufactured; and step 9, pre-assembly is conducted on the gangway main plate and the ship body section outer plate. According to the method, the goodness of fit between the mounted gangway and a complex linear ship body is improved, so that the watertight performance and the overall attractiveness of a ship body outer plate are guaranteed, and the hoisting efficiency of the gangway in the final assembly carrying stage is improved.

    本发明公开了一种船舶舷侧门高精度建造方法,包括以下步骤:步骤一、制作舷侧门胎架;步骤二、对舷侧门胎架设置反变形;步骤三、对船体分段外板进行开孔;步骤四、舷侧门主板与船体分段外板同胎铺设;步骤五、对船体分段外板进行装配焊接,测量船体分段外板焊前与焊后的尺寸,当船体分段的焊后与焊前尺寸在误差范围以内后,将船体分段外板吊离;步骤六、对舷侧门主板进行装配焊接;步骤七、安装铰链并进行同心度测量;步骤八、制作舷侧门定位对合线;步骤九、对舷侧门主板与船体分段外板实施预总组。本发明提高了舷侧门安装后与复杂线型船体的吻合度,从而保证了船体外板的水密性能和整体美观性,提高了舷侧门在总装搭载阶段的吊装效率。
