The position of other board:2.1以第一张板材为定位基准，依次吊装其他板材至胎架。2.1 Using the first sheet as the positioning reference, lifting other plates to the jig as follows.

5、2.2检查其他板材的尺寸及地线重合度，方法参照第一张板材的定位方法。2.2 Checking the other sheet size and the coincidence degree of ground marking, the positioning methods is similar with the first plate.三、曲型外板二次划线方法The third chapter: the second marking method of the curved external plate1.划线要保证其外观尺寸在理论数据范围内，同时须有相关的检验线，用以保证其外板线形和坡口的

6、尺寸。1. The ground marking must ensure the appearance size in the theoretical data range, at the same time, the inspection line is needed to ensure the outer plate alignment and the groove dimension.2.必须进行基准线施工（147/150mmM.K）,对于合拢时的肋检线等须敲上相关的洋冲。2. The reference line must be constructed (147/150mmM.K),

7、and the closure frame checking line must knock the checking points.3.划线结束后由施工队提出报验，精度管理人员对其尺寸进行复核使其在理论允许的误差范围内。3. The construction team should put forward the marking inspection, and the accuracy control department review the size to ensure the error within the allowable range theory.4.划线验收合格签字后进入下一

8、道工序。4. After inspection, the next procedure can be taken in.四.曲型片段的制作与控制办法The forth chapter: The typical segment production and control methods 曲型片段一般是由外板、肋骨、纵桁、肋板、肘板等构架组成，由的分段旁板还带有箱体、隔舱等，整个旁板都在胎架上进行组立，虽然结构有所不同，但是其组立方式基本相同。Typical fragment is generally composed by the outer plate, ribs, longitudinal

9、, frame, brackets and so on. Some side panels of the block will also composed by a box, compartment. The side plates are setted in the jig. Although the structure is different, the assembly methods are basically the same.1. 旁板的装配流程（以124-SS1A为例）1. The assembly procedure of the side plate (in the case

10、 of the 124-SS1A)1.1先装配前要根据图纸对结构的理论线进行确认1.1before the assembly we must confirm the theory line of the structure according to the drawings .1.2外板划线结束后，并对主要结构位置进行水平确认，水平调整到位后进行刚性支撑固定。1.2 After scribing, to confirm the level of the main structure, then rigid support fixed in place.1.3水平调整结束后进行上内部结构，先上纵

11、向的T拍并进行定位焊。然后进行肋板定位，肋板定位的时候必须注意与上口企口线对齐，所有肋位必须保证上口端面平齐。斜板端面和开口必须保证到位。1.3 After level adjustment, we can welded the internal structure. the longitudinal T bar is firstly located and welded. Then the frame is located, you must pay attention to ensure the upper end face is flush. The inclined plate sur

12、face and the opening must be secured in place.Ground ling management1.4肋骨装配，从上口企口位置开始定位一直到下口，保证企口位置在同一条直线上，而且保证肋骨与外板紧密贴合。1.4 Rib assembly, you should locate from the upper rabbet to the lower rabbet. We must ensure the rabbet in the same line and also ensure the ribs and the outer plate closely.1.5装

13、配完成后进行水平和尺寸自检，并报检B精度，B精度合格后开始关键位置焊接。1.5 After assembly, the construction team should take in the horizontal and size self-inspection, and apply “B” accuracy inspection. After passing the “B” accuracy inspection, the key structures can be welded.1.6焊接完成后拆除支撑固定，自检完成报检C精度，C精度合格后进行火工作业，最终合格后方可脱胎。1.6 Aft

14、er welding, the supporting and fixing can be removed. After self-inspection, the construction team should apply “C” accuracy inspection, then the explosive operation is allowed. Finally, the block can be removed from the jig.五.曲型分段的控制办法（以124分段为例）The fifth chapter: The control methods of typical bloc

15、ks(124 block as an example)曲型分段主要涉及到典型的轴舵系分段，机舱分段，舭部分段等。The typical segments are usually included shafting - rudder segment, engine room segment, bilge segment etc.按工作图上提供的施工要领、施工工艺并结合生产实际情况，按序吊装分段零、部件，其安装过程应采取下述必要措施。According to working drawing construction methods, construction process and combine
