工程名称海达广场分项工程名称现浇顶板内PVC管施工施工单位宁城县强盛建筑工程有限公司交底部位主体交底人接受人审核人交底日期交底内容：现浇顶板内PVC管施工一、划定灯头盒位置为了保证灯头盒位置的准确,首先应该根据设计图纸要求的灯具的型号,计算出灯头盒位置,如普通座灯头吸顶安装、普通吊线灯安装,灯头盒应该安装在房间的中心,而日光灯的灯头盒不能放在房间的中心。根据计算出的位置在模板上画出位置线，以免发生错误。二、固定灯头盒根据画出的位置线.把灯头盒初步固定在钢筋上,为了施工方便可选用活底盒,盒固定后先打开底板,连接管路,安装盒接头,然后用废纸或其他柔性材料将盒填塞密实,再固定好底板并加强灯头盒的固定。灯头盒必须封堵严密,以免灰浆渗人造成管路堵塞。三、敷设管路管路必须敷设在上下层钢筋之间,与钢筋绑扎固定。根据去向的不同,可以分为三种情况,第一种是从楼面内向上层引出的管路,第二种是从顶板向下引的管路,如向非承重隔墙板引出的开关管路,第三种是只在现浇顶板内敷设的管路。对于从楼地面向上层引出的管路,必须保证在上层墙体位置线内引出,可以参照土建梁或墙体的钢筋位置,注意向上部分管路不要跨越轴线而形成交叉,以免给后续施工带来不必要的麻烦。向上的管路在引出位置应固定一根不小于ф8的钢筋,用以固定位置和保护管路不受外力损伤折断。管口必须封堵严密,可以采用管堵封堵。在土建楼层放线后及时检查,对超出墙体线的管路,要及时进行处理,如果是根部超出,必须进行剔凿然后重新接管,如果是上部超出墙体线只需将其扳正,但要注意不能用力过猛,避免管路折断或变形。对于从顶板向下引的管路,为了不给土建模板造成较大的损害,采用暂时不引下,而等到土建拆模后再向下引的办法。具体做法是:在需要引下的位置预埋一块200×100×100mm的聚苯板,聚苯板要紧贴模板固定,把管头插入聚苯板中,并连接牢固紧密。等到土建拆模后安装隔墙板时.挖开聚苯板并将管路引下。既避免模板的损坏,又可以保证引下位置的准确。注意管口必须封堵严密,可以采用管堵封堵。对于只在现浇顶板内敷设的管路首先应该截取长度适当的管路,把管路一端与盒接头连接,并将盒接头与灯头盒固定,然后连接另一端。连接后把管路与钢筋绑扎固定。instrumenthasasingletestcondition,willbetransferredtothecoordinationofthetestphase,theinstrumentaccordingtothestand-alonetrialsscheduled,withtheprocesspreparationoftestsolutions,equippedwithprofessionaltechniciansandskilledworkers,toensuresafetyandquality.6.weldingengineeringconstructionprogramme6.1thisengineeringusedconstructionspecification6.1.1siteequipment,andindustrialpipelineweldingengineeringconstructionandtheacceptancespecificationGB50268-976.1.2oilchemicaltoxic,andcanburningmediapipelineengineeringconstructionandtheacceptancespecificationSH3501-20026.1.3oilchemicallowtemperaturesteelweldingproceduresSH/T3520-20046.1.4oilchemicalchromenickelAustrian"sbodysteel,andironnickelalloyandnickelalloypipelineweldingproceduresSH/T3523-19996.1.5SHJ520-92petrochemicalengineeringtechnicalspecificationforweldingofCR-MOheat-resistantsteelpipe6.1.6ofthepressurevesselNDT4730-946.2JBweldpreparation6.2.1constructionaccordingtothematerialsoftheprojectspecificationsandweldingmethods,providingqualifiedweldingprocedurequalificationreport.6.2.2qualifiedweldingprocedurequalificationbasedonthepreparationofweldinginstruction,guidethewelderweldingoperations.6.2.3whereparticipationinsitewelding,mustbeinpossessionofboilerandpressurevesselweldercertificatesissuedbytheLaborDepartment.6.2.4whereinvolvedinthepipeandsteelstructureweldingwelders,welderbeforeentryexaminationsshouldattendtheowners,andconstructionshouldbemadewithinthescopeandeligibilityapprovedbythequalityandtechnologysupervisiondepartmentsandowners.6.2.5qualifyforweldingwelder,weldingprocess,shouldbeapprovedbyweldingtheweldingprocess. 技术交底记录工程名称海达广场分项工程名称现浇顶板内PVC管施工施工单位宁城县强盛建筑工程有限公司交底部位主体交底人接受人审核人交底日期四、管路连接包括管路与管路的连接和管路与灯头盒的连接两种情况:管路与管路的连接:使用与管路配套的套管和专用粘按剂。连接前注意首先要清除被连接管端的灰尘等,保证粘接部位清洁干燥,用小毛刷涂抹胶粘剂,要均匀、不漏刷、不流坠。涂好后平稳地插入套管中,插接要到位。必要时可用力转动套管,保证连接可靠。套管连接的管路应保持平直。管路与灯头盒的连接:使用配套的盒接头和胶粘剂。首先根据两个灯头盒位置,截取适当长度的管路,长度不够时可以连接使用。按照上面套管与管路连接的办法,把盒接头的一端与管路连接,把盒接头的另一端插入盒内,并用配套的锁母固定。安装另一端的灯头盒时,盒接头安装后,可将管路或灯头盒稍撬起后插入并用配套的锁母固定。五、管路的切断对于直径在20mm以下的管路可以使用专用的剪管器(割管器)进行剪切,注意不能使切断的管口发生变形,对于直径在20mm以上的管路可以使用钢锯锯断,但必须用钢锉把管口内外的毛刺修整平齐。不能出现斜口,以避免接管时出现质量问题。六、管路的弯曲对于直径在25mm以下的管路,使用配套的弯管弹簧,首先将与管规格相配套的弯管弹簧插入需要煨弯的部位,如果管路长度大于弹簧长度可用铁丝拴牢弹簧的一端,并拉到合适的位置,两手抓住弯管弹簧的两端位置,用膝盖顶住被弯曲部位,两端用力逐渐煨出所需要的弯度,注意不能用力过快过猛,以免管路发生变形。对于直径在32mm以上的管路,使用弯管弹簧会有一定的困难,这时可以使用热煨法,首先将弯管弹簧插入管内,对规格较大的管路,没有配套的弯管弹簧时,可以把细砂灌入管内并振实,堵好两端管口,用电炉或热风机对需要弯曲部位进行均匀加热,加热到可以弯曲时,将管子的一端固定在平整的木板上,逐步煨出所需要的弯度,然后用湿布抹擦弯曲部位使其冷却定型。寒冷天气施工时可以把细砂炒热并把管路拿到室内预制。七、应注意的质量问题划定灯头盒位置时,容易出现灯位在房间内不居中的质量问题,可在施工前认真审图,注意房间内是否有吊壁柜的原因。固定灯头盒时电线管路内流入灰浆,造成堵管现象,可在堵盒前首先堵好管口。PVC管煨弯时出现凹扁现象,可选用配套的弯管弹簧,且热煨时保证煨弯部位受热均匀。八、其它未尽事宜，参照2014年赤峰市颁发的强制性条文执行。instrumenthasasingletestcondition,willbetransferredtothecoordinationofthetestphase,theinstrumentaccordingtothestand-alonetrialsscheduled,withtheprocesspreparationoftestsolutions,equippedwithprofessionaltechniciansandskilledworkers,toensuresafetyandquality.6.weldingengineeringconstructionprogramme6.1thisengineeringusedconstructionspecification6.1.1siteequipment,andindustrialpipelineweldingengineeringconstructionandtheacceptancespecificationGB50268-976.1.2oilchemicaltoxic,andcanburningmediapipelineengineeringconstructionandtheacceptancespecificationSH3501-20026.1.3oilchemicallowtemperaturesteelweldingproceduresSH/T3520-20046.1.4oilchemicalchromenickelAustrian"sbodysteel,andironnickelalloyandnickelalloypipelineweldingproceduresSH/T3523-19996.1.5SHJ520-92petrochemicalengineeringtechnicalspecificationforweldingofCR-MOheat-resistantsteelpipe6.1.6ofthepressurevesselNDT4730-946.2JBweldpreparation6.2.1constructionaccordingtothematerialsoftheprojectspecificationsandweldingmethods,providingqualifiedweldingprocedurequalificationreport.6.2.2qualifiedweldingprocedurequalificationbasedonthepreparationofweldinginstruction,guidethewelderweldingoperations.6.2.3whereparticipationinsitewelding,mustbeinpossessionofboilerandpressurevesselweldercertificatesissuedbytheLaborDepartment.6.2.4whereinvolvedinthepipeandsteelstructureweldingwelders,welderbeforeentryexaminationsshouldattendtheowners,andconstructionshouldbemadewithinthescopeandeligibilityapprovedbythequalityandtechnologysupervisiondepartmentsandowners.6.2.5qualifyforweldingwelder,weldingprocess,shouldbeapprovedbyweldingtheweldingprocess.
