4、梁板混凝土浇筑本工程1-7层梁、板混凝土强度为C25，柱随着高度的增加混凝土强度值减少，具体见砼强度等级表，因此在柱与梁交界处钢筋上固定钢丝网片进行分隔。梁、板混凝土随浇随振捣，随刮随抹平。用插入式振捣器振捣密实，刮杆刮平，在混凝土初凝前用木抹子抹平，在终凝前再进行二次抹压，并在表面用扫帚做拉毛处理，保证混凝土表面平整、密实无裂纹。5、柱混凝土浇筑在浇筑柱混凝土时要把模板内的杂物清干净，防止烂根，切要严格执行分层浇筑。在浇筑前要对柱体上表面凿毛，并清理干净，并用同等标号的砂浆平铺50-100mm，防止交接处出现裂缝。振捣时，振捣棒从下料点逐渐向外围移动，同时上下抽动振捣棒，辅助混凝土向四周流淌，要振捣密实，避免漏振6、雨天混凝土施工雨天混凝土施工同地下室混凝土雨天施工。如果雨后施工时，未浇混凝土的模板内有积水时，将预先留设的泄水孔打开排水。如果梁板上积水太深，模板内部积水无法排出时，应将预留洞口处梁板模板凿穿排除积水。六、混凝土试块的留置、施工记录混凝土抗压、抗渗试块在混凝土浇筑地点随机取样制作。1、留置原则剪力墙、梁板、柱的每一施工段、不同施工台班、不同标号的混凝土每100m³（包括不足100m³）制作一组标准养护抗压试块，2组同条件试块。当一次连续浇筑超过1000m³时，每200m³取样一次（包括不足200m³）地下室外墙抗渗混凝土每一施工段、不同施工台班每500m³（包括不足500m³）制作一组抗渗试块。2、后期处理制作的标准养护抗压、抗渗试块拆模后，当日即送往养护室进行标准养护，并做好记录。混凝土标准养护试块上书写内容为：工程名称、混凝土标号、成型时间、使用部位；同条件试块上书写内容为：工程名称、施工部位、混凝土标号、成型时间。同条件试块拆模后在试块上进行编号。3、同条件试块的养护、保护处理同条件试块拆模编号后，放到预先制作好的钢筋笼内，置于相同的施工部位与结构混凝土同条件养护；铁笼制作式样如下（净尺寸为500×200×200）：交底人接受交底人混凝土施工技术交底记录编号：表12-1工程名称施工图号qualityegg,chicken,...Developmentofpoultryindustrywilloccupyacertainareaofland,thereisamodernproductwithcomprehensiverollupof50,000chickenslayinghens,coversanareaof14.87hectares(233acres)more(includingOfficeofhatching,broodrearing,andlayingHouse,eggs,feedprocessingworkshop,Office,etc).Thepoultryindustryshouldworkinlandconservation,notaccountedfororlesscultivatedland,wasteland,theprincipleofslopeland.Whenthechickenfarmshouldgenerallynotavailabletolocalarablelandareatodetermineanappropriatelevelofbreedingsizeandnot,asinthepast,firstdeterminethesize,thengototheexpropriation.3.energy-saving,water-savingawarenessinthe1970ofthe20thcentury,thepigandchickenfarmmechanizationinourcountryforwardundertheslogan,thecountrystartedbuildingamodernlargechickenfarmsintheclimax.Wasbuiltasthefullyenclosedintensivechickenfarms,usingartificiallight,mechanicalfeedingandmandatoryventilation,asmallnumberofchickenfarmsalsousemechanicalsetseggsandmanure.Accordingtostatistics,fullyenclosedchickencoopperchickenwhentheannualelectricityconsumptionof10-kilowatt•,halfopenedthehenhousewhen•2~5kW(open),whentheentireopeningis0.5kW•,rollingopenshedsat0.45kW•.Henhousetypes,powerconsumptiondifferenceisverybig,adifferenceof10~20.China"senergysupplyisinshortsupply.Therefore,indeterminingthebreeding,poultryequipmentselectionshouldtakefullconsiderationofenergysavingissues.LackoffreshwaterresourcesinChina,theaverageannualprecipitationis600mm.19882474cubicmetersofwaterpercapitainChina,only1/4ofthepopulationallovertheworld,nowreducedto2300cubicmeters.Hendailywaterintaketoabout1.5~2times,sowhenyou第13页共13页 2005002004、混凝土施工记录每次混凝土浇筑后，混凝土专业工程师都必须填写《混凝土施工记录》。七、混凝土的养护在剪力墙、柱混凝土浇筑完毕且拆模后，在混凝土表面涂刷养护液；梁板在混凝土浇筑后的12小时内浇水养护，养护时间不得于7天，抗渗混凝土不得少于14天，以保持混凝土具有足够湿润状态。混凝土在养护过程中，如发浇水不足，以致表面泛白或出现干缩细小裂缝时，要立即采取覆盖，加强养护工作，充分浇水，并延长浇水日期，加以补救。在已浇筑的混凝土强度达到1.2N/mm2以后，始准在其上来往行人和安装模板及支架等。八、混凝土拆模墙混凝土拆模强度不得低于1.2mPa。梁板混凝土拆模时拆模强度必须以混凝土同条件试块抗压强度报告为准，不同施工段、不同结构件的混凝土拆模强度报告归档保存。不同的混凝土结构件拆模所需强度见下表：结构类型结构件跨度（米）混凝土占设计强度标准值的百分率板≤2502<且≤875梁≤875＞8100悬臂梁＞2100交底人接受交底人混凝土施工技术交底记录编号：表12-1工程名称施工图号qualityegg,chicken,...Developmentofpoultryindustrywilloccupyacertainareaofland,thereisamodernproductwithcomprehensiverollupof50,000chickenslayinghens,coversanareaof14.87hectares(233acres)more(includingOfficeofhatching,broodrearing,andlayingHouse,eggs,feedprocessingworkshop,Office,etc).Thepoultryindustryshouldworkinlandconservation,notaccountedfororlesscultivatedland,wasteland,theprincipleofslopeland.Whenthechickenfarmshouldgenerallynotavailabletolocalarablelandareatodetermineanappropriatelevelofbreedingsizeandnot,asinthepast,firstdeterminethesize,thengototheexpropriation.3.energy-saving,water-savingawarenessinthe1970ofthe20thcentury,thepigandchickenfarmmechanizationinourcountryforwardundertheslogan,thecountrystartedbuildingamodernlargechickenfarmsintheclimax.Wasbuiltasthefullyenclosedintensivechickenfarms,usingartificiallight,mechanicalfeedingandmandatoryventilation,asmallnumberofchickenfarmsalsousemechanicalsetseggsandmanure.Accordingtostatistics,fullyenclosedchickencoopperchickenwhentheannualelectricityconsumptionof10-kilowatt•,halfopenedthehenhousewhen•2~5kW(open),whentheentireopeningis0.5kW•,rollingopenshedsat0.45kW•.Henhousetypes,powerconsumptiondifferenceisverybig,adifferenceof10~20.China"senergysupplyisinshortsupply.Therefore,indeterminingthebreeding,poultryequipmentselectionshouldtakefullconsiderationofenergysavingissues.LackoffreshwaterresourcesinChina,theaverageannualprecipitationis600mm.19882474cubicmetersofwaterpercapitainChina,only1/4ofthepopulationallovertheworld,nowreducedto2300cubicmeters.Hendailywaterintaketoabout1.5~2times,sowhenyou第13页共13页 九、成品保护阴阳角防护示意图梁板混凝土浇筑后在强度达到1.2MPa以前，不允许在上面踩踏。在混凝土结构件拆模后，在柱角、墙角、楼梯踏步、门窗洞口处钉150mm宽木板条防护阳角。柱、墙防护高度为1.5m，洞口周边全部防护。具体做法见下图：十、混凝土施工安全要求1、混凝土施工人员浇筑外墙混凝土时，不得将外墙钢筋作为扶手站在外模背楞上。2、每次混凝土浇筑前，必须彻底检查操作平台是否稳固，连接螺栓是否牢靠。操作平台水平扶手在浇筑混凝土前必须及时搭设，以确保施工人员安全。3、检查振捣棒、信号灯电源是否完好，有无漏电现象。同时振捣棒配电箱、振捣棒电动机以及铁锹、锤子等施工用具必须放置平稳，防止其从操作平台或外架子上掉落伤人。4、振捣手必须戴绝缘手套，穿平底胶鞋。5、混凝土泵车进场施工队有专人指挥、调度，任何机动车在场内行走都由专人指挥，倒车时还要响笛警示。6、布料机端头的软管必须连接牢固。夜间施工要有足够的照明设备，并在使用前对照明用具及供电线路进行检查。交底人接受交底人混凝土施工技术交底记录编号：表12-1工程名称施工图号qualityegg,chicken,...Developmentofpoultryindustrywilloccupyacertainareaofland,thereisamodernproductwithcomprehensiverollupof50,000chickenslayinghens,coversanareaof14.87hectares(233acres)more(includingOfficeofhatching,broodrearing,andlayingHouse,eggs,feedprocessingworkshop,Office,etc).Thepoultryindustryshouldworkinlandconservation,notaccountedfororlesscultivatedland,wasteland,theprincipleofslopeland.Whenthechickenfarmshouldgenerallynotavailabletolocalarablelandareatodetermineanappropriatelevelofbreedingsizeandnot,asinthepast,firstdeterminethesize,thengototheexpropriation.3.energy-saving,water-savingawarenessinthe1970ofthe20thcentury,thepigandchickenfarmmechanizationinourcountryforwardundertheslogan,thecountrystartedbuildingamodernlargechickenfarmsintheclimax.Wasbuiltasthefullyenclosedintensivechickenfarms,usingartificiallight,mechanicalfeedingandmandatoryventilation,asmallnumberofchickenfarmsalsousemechanicalsetseggsandmanure.Accordingtostatistics,fullyenclosedchickencoopperchickenwhentheannualelectricityconsumptionof10-kilowatt•,halfopenedthehenhousewhen•2~5kW(open),whentheentireopeningis0.5kW•,rollingopenshedsat0.45kW•.Henhousetypes,powerconsumptiondifferenceisverybig,adifferenceof10~20.China"senergysupplyisinshortsupply.Therefore,indeterminingthebreeding,poultryequipmentselectionshouldtakefullconsiderationofenergysavingissues.LackoffreshwaterresourcesinChina,theaverageannualprecipitationis600mm.19882474cubicmetersofwaterpercapitainChina,only1/4ofthepopulationallovertheworld,nowreducedto2300cubicmeters.Hendailywaterintaketoabout1.5~2times,sowhenyou第13页共13页 7、电源线路要悬空移动，避免电源线与地面和钢筋相摩擦及挤压；架空电线支架必须采用木质绝缘材料；电源线用带绝缘皮的粗软线绑扎在支架上；经常检查电源线，发现破损及时处理。8、作业工人必须戴好安全帽，临边作业必须系好安全带。9、混凝土浇筑过程中临时断料时，作业工人不得躺在作业层跳板上休息。10、每次混凝土施工前，责任工程师必须口头对作业工人进行安全技术交底。十一、环境要求1．混凝土浇筑在白天进行，尽量避免在夜间进行混凝土浇筑施工，混凝土泵车周围用隔音材料比如苯板等进行围挡，以免干扰周边居民。2．泵车停放位置必须设置停放平台，防止泵车漏油污染现场土壤。同时泵车附近砌筑污水沉淀池，便于清洗泵管和混凝土罐车放料口的污水重新利用。3．要求混凝土罐车在放料口位置设置接漏斗，防止混凝土运输过程中洒落的混凝土掉到城市交通道路上。4．墙体混凝土浇筑过程中，必须配备两块辅助下料的木板，防止混凝土洒落到楼板上，造成浪费。5．振捣棒不得直接在钢筋上振动，以免发出刺耳的声音。同时不得用钢管砸模板背面，以免造成模板面凹凸变形，影响墙体混凝土的清水效果，产生噪音。十二、成本降低措施1、剪力墙混凝土浇筑时，尽量减少落地混凝土。2、墙体混凝土浇筑时，控制好墙顶混凝土标高，防止标高超限，增加凿毛的工程量，并减少混凝土的浪费。3、用海绵球辅助冲洗泵管，减少混凝土浪费。交底人接受交底人qualityegg,chicken,...Developmentofpoultryindustrywilloccupyacertainareaofland,thereisamodernproductwithcomprehensiverollupof50,000chickenslayinghens,coversanareaof14.87hectares(233acres)more(includingOfficeofhatching,broodrearing,andlayingHouse,eggs,feedprocessingworkshop,Office,etc).Thepoultryindustryshouldworkinlandconservation,notaccountedfororlesscultivatedland,wasteland,theprincipleofslopeland.Whenthechickenfarmshouldgenerallynotavailabletolocalarablelandareatodetermineanappropriatelevelofbreedingsizeandnot,asinthepast,firstdeterminethesize,thengototheexpropriation.3.energy-saving,water-savingawarenessinthe1970ofthe20thcentury,thepigandchickenfarmmechanizationinourcountryforwardundertheslogan,thecountrystartedbuildingamodernlargechickenfarmsintheclimax.Wasbuiltasthefullyenclosedintensivechickenfarms,usingartificiallight,mechanicalfeedingandmandatoryventilation,asmallnumberofchickenfarmsalsousemechanicalsetseggsandmanure.Accordingtostatistics,fullyenclosedchickencoopperchickenwhentheannualelectricityconsumptionof10-kilowatt•,halfopenedthehenhousewhen•2~5kW(open),whentheentireopeningis0.5kW•,rollingopenshedsat0.45kW•.Henhousetypes,powerconsumptiondifferenceisverybig,adifferenceof10~20.China"senergysupplyisinshortsupply.Therefore,indeterminingthebreeding,poultryequipmentselectionshouldtakefullconsiderationofenergysavingissues.LackoffreshwaterresourcesinChina,theaverageannualprecipitationis600mm.19882474cubicmetersofwaterpercapitainChina,only1/4ofthepopulationallovertheworld,nowreducedto2300cubicmeters.Hendailywaterintaketoabout1.5~2times,sowhenyou第13页共13页'
