四、胎架管理要求：
胎架检验须提前半天报检.
胎架检验不合格不允许进入下道工序.
胎架需要修正的须进行复检.
一、分段铺板、划线精度控制：
1.划线原则：
1）划线测量原则：从中线向两侧,从中部向两端.即：以工作面中心线为“0”点分别向左右量取,以基准肋位线为“0”点分别向前后量取.2) 对工艺设计加放的焊接收缩量,必须按照图纸要求加放在肋位或纵骨间距中,不得将其全部放在合拢端.3) 卷尺测量要求：测量必须使用检验合格的长卷尺,连续累加数据量取各点,不允许用短尺逐段测量,减小积累误差.4) 对于板片上原有的数控线,目前仅作参考,所有结构线均需二次划线.

2．平面胎架铺板划线
1) 根据图纸要求将拼接合格的基面板放置于检验合格的胎架上；
2) 根据要求调整板的位置,控制板边缘与胎架支撑点间距不大于200mm；
3) 对基面板进行定位,检验每个柱头与基面板之间的密贴情况,密贴率大于95%,最大间隙控制在3mm以内；
4) 将基面板和胎架进行死胎固定,固定的原则：大接缝端口全部固定,强构件的位置全部固定；
5) 死胎结束后方可进行划线：根据图纸要求开角尺,划出肋检线和假定中心线,以此为基准根据划线图纸尺寸划制构架线,边缘划出100mm精控对合线,基面板边缘有余量的划出余量线； 6) 基面板反面需要安装隔舱下墩、围井等结构的须将结构安装线划出,并反驳到基面板反面,同时划出100mm安装检验线位置,并敲样冲标记.

Four,jig management requirements:
Jig inspection must be half a day inspection in advance.
Jig inspection unqualified not allow into the next process.
Must re-examine jig need to be modified.
A,segmented planking,laying-out precision control:
1.Line principle:
1) line measurement principle:from line to the side and from middle to both ends.I.e.,with the center line of the working face is "0" point to the left and right sides respectively,with benchmark rib bit line as "0" point after forward quantity respectively.2) to process design and welding shrinkage,must,in accordance with the drawings requirements added as the rib and longitudinal spacing,it may not be all on the closed end.3) tape measure requirements:long measuring tape measurement must be used to inspection,and continuous accumulation data volume in each point,short feet intervals are not allowed to use to measure and reduce error accumulation.4) for the plate on the original CNC line,at present are for reference only,all the structure line must be second line.

2.The flat tire rack plating line
1) place the splicing qualified base panel according to your drawings to inspection of the tire rack;
2) adjust the position of the plate according to the edge of the panel and the tire rack support spacing is not greater than 200 mm;
3) fixing the base panel,check each stigma and panel between the dense paste,paste rate greater than 95%,the largest gap control in less than 3 mm;
4) will be the base panel and jig for stillbirth fixed,fixed principle:the big joint port all fixed,fixed; strong component of the position
5) stillbirth rear end can be crossed:open square,according to your drawings to draw rib inspection line and the assumed center line,as the benchmark according to cross line drawing size frame lines,edge to draw 100 mm fine point joining lines,the base panel edge line have allowance to get allowance; 6) tails need to install the base panel bulkhead under the pier,trunk of structure should be the structure of the installation of the line of draw,and refute opposite to the base panel,at the same time draw 100 mm test line installation position,and knocked at the sample tag.
