技术、安全交底单工程名称巢湖市第一人民医院门诊综合楼工程项目经理施工班组施工单位中建八局第三建设有限公司技术负责人班组长交底内容分项工程名称：钢筋加工钢筋的除锈可采用机械除锈和手工除锈两种方法：1）机械除锈可采用钢筋除锈机或钢筋冷拉、调直过程除锈；2）手工除锈可采用钢丝刷、砂盘、喷砂和酸洗除锈。在除锈过程中发现钢筋表面的氧化层脱落现象严重并已损伤钢筋截面，或在除锈后钢筋表面有严重的麻坑、斑点削弱钢筋截面时，不宜使用或经试验降级使用。2、调直：钢筋应平直，无局部曲折。对于盘条钢筋在使用前应调直，调直可采用调直机和卷扬机冷拉调直钢筋两种方法。1）当采用钢筋调直机时，要根据钢筋的直径选用调直模和传送压辊，要正确掌握调直模的偏移量和压辊的压紧程度。调直模的偏移量根据其磨耗程度及钢筋品种通过试验确定；调直筒两端的调直模一定要在调直前后导孔的轴心线上。压辊的槽宽一般在钢筋穿入压辊之后，在上下压辊间宜有3mm之内的空隙。切断：在切断过程中，如发现钢筋有劈裂、缩头或严重的弯头等必须切除。1）将同规格钢筋根据不同长度长短搭配，统筹排料；一般应先断长料，后断短料，减少短头，以减少损耗；2）断料应避免用短尺量长料，以防止在量料中产生累计误差。宜在工作台上标出尺寸刻度并设置控制断料尺寸用的挡板。4弯曲成型：钢筋成型形状要正确，平面上不应有翘曲不平现象；弯曲点处不能有裂缝。1）钢筋弯曲前，对形状复杂的钢筋应将各弯曲点位置划出。划线是要根据不同的弯曲角度扣除弯曲调整值，其扣法是从相邻两段长度中各扣一半；划线宜从钢筋中线开始向两边进行；2）钢筋在弯曲机上成型时，心轴直径应满足要求，成型轴宜加偏心轴套以适应不同直径的钢筋弯曲需要。弯曲细钢筋时，为了使弯弧一侧的钢筋保持平直，挡铁轴宜做成可变挡架或固定挡架。5.3.3成品保护boxbeforecommissioning,checkdistributionboxthereisnodebris,installationinaccordancewiththecriteriaofqualityassessment,chromatography,platesarecomplete.2boxesinsidethedoorsandframes,andgroundedorneutralexamination.3withelectricopeningdoors,doorandframegroundterminalapplyingbarebraidedcopperwireconnectionsandgroundingidentifies.4connectionoftheprotectiveconductorshouldbeexposedintheexternalprotectiveconductorTerminal.5lightingshouldbesettingthezerolinebox(n)andprotectiveground(PE)bus,zerolineandprotectthegroundbusdistribution.6laidgroundlinesalongthelengthofevery15-100mmrespectively,coatedwithyellowandgreenstripes.7testinggroundingresistanceofgroundingdevicesmustcomplywiththedesignrequirements.8boxesofchecks:basedonchangesofdesigndrawingsandconstructiondocuments,checkboxinthecomponentspecification,model,installationlocationshouldbecorrect;boxesonbothsidesoftheTerminalcannotlack;theconductorcrosssectionshouldmeettherequirementsofdrawings;line-by-linecheckboxinthedevice"sconnectionandtheconnectionoftheequipmenttotheterminalblockinsidethebox.9boxtiecablecheck:liaisonbetweentheboxandtheboxcablesrequiredbyproofing;checklinesonthecircuitatthesametimeshouldcheckthewires,cables,relays,switches,buttons,terminalblocksmarkedwithlinedrawings.10operatorchecks:themaincheck
