12、使用的钢筋挂上已送检的标识牌，对TCM已批准使用的钢筋挂上准用的标识牌。Eachbatchofbarsdeliveredtothejobsiteshallbeprovidedwithmanufacturer,Stestreports.Ifthereisnosuchreport,spottestshallbecarriedout.Barsshallbestoredbytheirspecsandtypes.Forthosesteelbarsdeliveredtothesitebutnotbeingchecked,tagthemwitha“tobechecked“markingcard.Fortho

14、外皮尺寸，根据检查结果调整钢筋下料表，使加工成型的钢筋尺寸符合规范及TCM标准公差要求。对于尺寸较长的钢筋，计算下料尺寸时，考虑锚固、搭接长度及搭接接头位置。Thelengthofthebarsshallbecalculatedbythecivilengineerwhohasmadeagoodstudyofthedrawings,takingthebendingpartsintoconsideration.Trialcutofthebarsshallbeperformedaccordingtothebarscheduleandcheckthelengthoftheedgebends,bendi
