  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.
