1前言随着高层建筑的迅速发展，现代科学技术不断进步，附着式升降脚手架广泛运用在高层建筑领域。我司自行研制的FDJ-7型整体可分段附着升降脚手架，其研究与应用成果通过国家建筑城建机械质检中心和省建委鉴定，升降脚手架滑轮式防倾器2008年11月12日获得国家实用新型专利，该升降架具有构造简单、省工省料、施工快捷、操作简便、安全可靠、满足高层和超高层建筑的施工要求等优点，先后在长沙华天贵宾楼、湖南省建委培训综合楼、中南大学湘雅三医院外科病房楼等多个工程中应用，经总结其施工技术经验形成此工法。2工法特点2.1附着升降外架一次安装完成后、随主体同步上升、随装修同步下降，升降过程不需吊车配合，减少了垂直运输设备施工压力和安全事故的发生机率。2.2适用高层快速施工、升（降）过程仅2小时。2.3可整体同步升降、也可分段升降，能满足土建分区域施工的要求。2.4架体垂直、稳定、安全可靠。2.5与悬挑脚手架相比，减少了架子反复搭拆过程中架体上灰尘对环境造成的污染，并可减少架子和安全防护材料，节约投资40%左右。3适应范围适应于现浇钢筋混凝土结构高层和超高层建筑主体及外装饰施工。2012.10grinderJ3SL-400420091000goodcorporate2012.10circularsawMJ22542010200goodcorporate2012.10woodMB904420091800goodChinacompany2012.10grinderJ3SL-40042009good200company2012.10drill2012.10drill12~15mm36China20111000goodcompany2009500manualhoistgoodcorporate2012.102T~5T102010200goodcorporate2012.10electrichoists5T22010450goodcompany2012.10hydraulicjack15-30t202006158goodcompany2MechanicalJack16-20T20012.10200730goodcompaniesgoodcorporate2012.10pump2China20082012.10...Namespecificationsunitsofmeasurementquantitiesnotetotal20122013reinforcedt-12702701000diesel270100170Portlandcement42.5t0#t12500250010000M3ofsandM323000300020000macadam34100410030000M3blocks890030005900platet13203201000mPVCpipeofpenstock16306301000rubbersealingstripcopperwaterstopm240120120mM32001001001005050woodfoamM21200600600tt403010detonatorsinexplosive400003000010000kW501000100000410000Qualityassurancemeasuresforconstructionofthe14thchapter14.1thequalitypolicyandqualityobjective14.1.1thequalitypolicyqualitypolicyofourBureau:scientificmanagement,continuousimprovement,buildqualityconstruction,customersatisfaction.13 4工艺原理4.1工艺原理4.1.1本架由基本架体、升降系统和安全保护装置三部分组成。基本架体由上部操作架、底部定型水平桁架、竖向主框架及承力座组成，升降系统由电动提升机、钢梁、斜拉杆、电控柜等组成。安全保护装置由同步荷载控制系统、滑轮式防倾装置和导轨防坠装置等组成如下图。4.1.2本架由若干单元架体组合而成，基本架体的底部水平桁架两端均支撑在竖向主框架和承力座上，上部操作架搭设在底部水平桁架2012.10grinderJ3SL-400420091000goodcorporate2012.10circularsawMJ22542010200goodcorporate2012.10woodMB904420091800goodChinacompany2012.10grinderJ3SL-40042009good200company2012.10drill2012.10drill12~15mm36China20111000goodcompany2009500manualhoistgoodcorporate2012.102T~5T102010200goodcorporate2012.10electrichoists5T22010450goodcompany2012.10hydraulicjack15-30t202006158goodcompany2MechanicalJack16-20T20012.10200730goodcompaniesgoodcorporate2012.10pump2China20082012.10...Namespecificationsunitsofmeasurementquantitiesnotetotal20122013reinforcedt-12702701000diesel270100170Portlandcement42.5t0#t12500250010000M3ofsandM323000300020000macadam34100410030000M3blocks890030005900platet13203201000mPVCpipeofpenstock16306301000rubbersealingstripcopperwaterstopm240120120mM32001001001005050woodfoamM21200600600tt403010detonatorsinexplosive400003000010000kW501000100000410000Qualityassurancemeasuresforconstructionofthe14thchapter14.1thequalitypolicyandqualityobjective14.1.1thequalitypolicyqualitypolicyofourBureau:scientificmanagement,continuousimprovement,buildqualityconstruction,customersatisfaction.13 上。脚手架的升降是通过底部水平桁架、竖向主框架、承力座和提升系统的交替实现升降。工作状态时承力座用斜拉杆和穿墙螺栓固定在建筑物上，承力座主要承受由底部桁架传来的所有荷载，同时通过斜拉杆和穿墙螺栓卸力于建筑物，上部架体按规范要求设置连墙杆；竖向主框架上安装滑轮式防倾装置和导轨防坠装置。升降状态时钢梁用斜拉杆和穿墙螺栓固定在承力座上部建筑物上，安装于钢梁上的电动提升机吊钩与承力座吊环相接，松开承力座穿墙螺栓、斜拉杆及架体连墙杆，使架体呈自由状态悬挂于电动提升机上，此时防倾装置约束架体的内外倾覆。同步电动葫芦完成架体的升降。所有荷载由钢梁通过斜拉杆和穿墙螺栓传递给建筑物。完成一次升、降后，钢梁、电动葫芦的升、降由手动葫芦完成。4.1.3正常状态下防坠装置不工作。当电动葫芦出现断链或各提升设备间高差大于30㎜，同步荷载控制系统动作电气联动防坠装置瞬间动作(锁定架体下坠时间2秒)自动锁住防坠导轨，防止架体下坠。2012.10grinderJ3SL-400420091000goodcorporate2012.10circularsawMJ22542010200goodcorporate2012.10woodMB904420091800goodChinacompany2012.10grinderJ3SL-40042009good200company2012.10drill2012.10drill12~15mm36China20111000goodcompany2009500manualhoistgoodcorporate2012.102T~5T102010200goodcorporate2012.10electrichoists5T22010450goodcompany2012.10hydraulicjack15-30t202006158goodcompany2MechanicalJack16-20T20012.10200730goodcompaniesgoodcorporate2012.10pump2China20082012.10...Namespecificationsunitsofmeasurementquantitiesnotetotal20122013reinforcedt-12702701000diesel270100170Portlandcement42.5t0#t12500250010000M3ofsandM323000300020000macadam34100410030000M3blocks890030005900platet13203201000mPVCpipeofpenstock16306301000rubbersealingstripcopperwaterstopm240120120mM32001001001005050woodfoamM21200600600tt403010detonatorsinexplosive400003000010000kW501000100000410000Qualityassurancemeasuresforconstructionofthe14thchapter14.1thequalitypolicyandqualityobjective14.1.1thequalitypolicyqualitypolicyofourBureau:scientificmanagement,continuousimprovement,buildqualityconstruction,customersatisfaction.13

8安全措施8.1使用前，应根据工程结构特点、施工环境、条件及施工要求编制“附着升降脚手架专项施工组织设计”，并按国家规定办理相关手续。8.2组装、每次升降以及拆卸前，必须对有关施工人员进行书面的安全技术交底，施工人员必须经过培训合格、持证上岗,安全防护用品佩戴齐全,严格执行升降架的作业程序规定和技术要求。8.3工程结构混凝土强度应达到附着支承对其附加荷载的要求；物料平台所在跨的附着升降架应单独升降，并应采取加强措施。8.4在使用过程中每月进行一次全面安全检查，机电设备定期进行检查、维修和保养，每次升、降前后必须履行分段验收。升降架到位固定完毕，必须办理交付使用手续，方可投入使用。8.5每次升降应清除架上障碍物、所有升降作业要求解除的约束必须拆开，架体升降时，外架上严禁站人。并设置安全警戒线，架体下部15m范围内严禁站人，并派专人监护。8.6架体上各种构配件、连墙杆和机电设备严禁拆除，架面荷载严禁超过200㎏，严禁堆放易燃易爆物品，做好防火工作。8.7动力设备、控制设备、防坠防倾装置、同步荷载控制系统，应有防雨、防砸、防尘等措施；临时用电采用TN-S系统。8.8遇有五级（含五级）以上大风和大雨、大雪、浓雾和雷雨等天气时，禁止进行升降和拆卸作业，并应预先对架体采取加固措施。夜间禁止进行升降作业。2012.10grinderJ3SL-400420091000goodcorporate2012.10circularsawMJ22542010200goodcorporate2012.10woodMB904420091800goodChinacompany2012.10grinderJ3SL-40042009good200company2012.10drill2012.10drill12~15mm36China20111000goodcompany2009500manualhoistgoodcorporate2012.102T~5T102010200goodcorporate2012.10electrichoists5T22010450goodcompany2012.10hydraulicjack15-30t202006158goodcompany2MechanicalJack16-20T20012.10200730goodcompaniesgoodcorporate2012.10pump2China20082012.10...Namespecificationsunitsofmeasurementquantitiesnotetotal20122013reinforcedt-12702701000diesel270100170Portlandcement42.5t0#t12500250010000M3ofsandM323000300020000macadam34100410030000M3blocks890030005900platet13203201000mPVCpipeofpenstock16306301000rubbersealingstripcopperwaterstopm240120120mM32001001001005050woodfoamM21200600600tt403010detonatorsinexplosive400003000010000kW501000100000410000Qualityassurancemeasuresforconstructionofthe14thchapter14.1thequalitypolicyandqualityobjective14.1.1thequalitypolicyqualitypolicyofourBureau:scientificmanagement,continuousimprovement,buildqualityconstruction,customersatisfaction.13 9环保措施9.1材料、设备机具进入现场合理堆放，避免二次搬运。9.2架体组装时，架上做到工完料清，升降前及时清理架体上的垃圾。9.3按计划配置材料、设备，剩余物品及时清理入库。10效益分析该工法技术先进、安全可靠，经济效益和社会效益十分显著。升降架与传统外脚手架相比无论从材料、安全防护和劳动用工等方面比较，都具有良好的优势。以建筑物总高度100m为例：与落地架手架相比材料投入仅为12﹪左右，安全防护为18﹪，劳动用工仅为15﹪，可降低成本55﹪左右。与悬挑脚手架相比，材料投入约为50﹪，安全成本防护约为20﹪，劳动用工约为11﹪，可降低成本38﹪左右。附着升降外架一次安装完成后、随主体同步上升、随装修同步下降，升降过程不需吊车配合，减少了垂直运输设备施工压力和安全事故的发生机率，可节约垂直运输设备费用20%左右。附着升降外架与主体和外装修同步升降，施工速度快。与悬挑脚手架相比，减少了架子反复搭拆过程中架体上灰尘对环境造成的污染，具有显著的社会效益。11应用实例11.1长沙****宾楼2000年开工，2002年竣工，位于长沙市****建筑面积28000㎡，建筑总高度108米，建筑物外形复杂，⑦轴、2/01轴两向剪力墙外倾，外倾角度为7度，屋顶与地面的外倾水平距离为2012.10grinderJ3SL-400420091000goodcorporate2012.10circularsawMJ22542010200goodcorporate2012.10woodMB904420091800goodChinacompany2012.10grinderJ3SL-40042009good200company2012.10drill2012.10drill12~15mm36China20111000goodcompany2009500manualhoistgoodcorporate2012.102T~5T102010200goodcorporate2012.10electrichoists5T22010450goodcompany2012.10hydraulicjack15-30t202006158goodcompany2MechanicalJack16-20T20012.10200730goodcompaniesgoodcorporate2012.10pump2China20082012.10...Namespecificationsunitsofmeasurementquantitiesnotetotal20122013reinforcedt-12702701000diesel270100170Portlandcement42.5t0#t12500250010000M3ofsandM323000300020000macadam34100410030000M3blocks890030005900platet13203201000mPVCpipeofpenstock16306301000rubbersealingstripcopperwaterstopm240120120mM32001001001005050woodfoamM21200600600tt403010detonatorsinexplosive400003000010000kW501000100000410000Qualityassurancemeasuresforconstructionofthe14thchapter14.1thequalitypolicyandqualityobjective14.1.1thequalitypolicyqualitypolicyofourBureau:scientificmanagement,continuousimprovement,buildqualityconstruction,customersatisfaction.13
