6、內(nèi)容墩身鋼筋加工及安裝一、鋼筋加工墩身鋼筋采用型號HRB400的Φ14螺紋鋼和型號HPB300的φ10光圓鋼筋，墩身鋼筋在鋼筋加工場加工成半成品，運至現(xiàn)場綁扎，進行鋼筋下料時（鋼筋詳細尺寸詳見通橋（2009）4301-I、-II），一定要考慮墩身四周結構主筋受承臺內(nèi)預埋墩身鋼筋高度不統(tǒng)一的影響因素。為保證墩頂鋼筋高度一致，墩身外側豎向結構主筋下料時，頂部彎鉤先不設，鋼筋下料長度按照預埋最低鋼筋高度來計，待鋼筋安裝到墩頂時再由人工利用小型機具彎曲。墩身鋼筋按規(guī)范進行焊接，鋼筋搭接必須滿足規(guī)范要求，鋼筋單面焊焊接長度不小于10d，雙面焊焊接長度不小于5d
7、，必須達到無假焊、脫焊、燒傷鋼筋的現(xiàn)象，焊接完成后必須敲掉藥皮，焊縫飽滿。鋼筋網(wǎng)片之間采用架立鋼筋焊接牢固，做到上下層網(wǎng)格對齊，層間距正確，并確保鋼筋的保護層厚度。施工墩身同時要確保承臺施工時預留墩身鋼筋長度滿足規(guī)范要求。鋼筋加工允許偏差HOMEPAGE.Openingofthecompany'sextranet,everyemployeeinthecompany'svariouspointaccesstoinformationontheINTERNETnetwork...Nodescanbeextendedto1000M,supportshared
