建筑施工·第45卷·第1期67可调节应力反拉骑墙式吊篮冗余保护体系研究应用王铭浩王文通蔡宝清中国建筑第二工程局有限公司北京100060摘要：为避免建筑施工中高处作业吊篮坠落事故，结合郑州银行金融服务中心工程进行了可调节应力反拉骑墙式吊篮冗余保护体系的研究。针对常规反拉骑墙式吊篮薄弱环节，依据冗余安全度治理原则，定向研究屋顶双层花架梁上高空载人反拉骑墙式吊篮冗余保护体系，利用不同细部保护机制，建立安全冗余防线，控制事故隐患。经过现场各方多次组织检查验收工作，吊篮使用工况非常良好，未出现安全重大隐患，各项均满足项目要求，并取得了良好的效益，可为类似工程提供借鉴。关键词：花架梁；抱箍反拉；吊篮；冗余保护中图分类号：TU69文献标志码：A文章编号：1004-1001(2023)01-0067-04DOI：10.14144/j.cnki.jzsg.2023.01.017ResearchandApplicationofRedundantProtectionSystemofAdjustableStressBackPullWallMountedHangingBasketWANGMinghaoWANGWentongCAIBaoqingChinaConstructionSecondEngineeringBureauCo.,Ltd.,Beijing100060,ChinaAbstract:Inordertoavoidthefallingaccidentofhangingbasketinhighplaceoperationduringconstruction,theredundantprotectionsystemofadjustablestressbackpullwallmountedhangingbasketisstudiedincombinationwiththefinancialservicecenterprojectofBankofZhengzhou.Inviewoftheweaklinksofconventionalbackpullwallmountedhangingbaskets,accordingtotheprincipleofredundancysafetymanagement,theredundantprotectionsystemofoverheadmannedbackpullwallmountedhangingbasketsontheroofdoubledeckedracksisstudieddirectionally,anddifferentdetailprotectionmechanismsareusedtoestablishsafetyredundancydefenselinestocontrolpotentialaccidents.Aftermanyinspectionsandacceptancesorganizedbyallpartiesonthesite,theworkingconditionofthehangingbasketisverygood,andthereisnomajorpotentialsafetyhazard.Allitemsmeettheprojectrequirements,andgoodbenefitshavebeenachieved,whichcanprovidereferenceforsimilarprojects.Keywords:flowerrackbeam;backpullandhoop;hangingbasket;redundantprotection心为框架-核心筒结构，办公楼、档案中心及数据中心为框剪力墙结构，其余连廊、裙房等均为框架结构。本工程屋面结构设计为双层花架梁结构，出屋面高度9.1m，双层花架梁间距4.2...
