摘　　要：针对坡屋面支设电动吊篮施工难题,研究并对比分析各类型施工方案,最终选择取消吊篮后支腿,直接将吊篮大臂后端采用钢丝绳与坡屋面结构梁捆绑固定的吊篮支设方式。阐述该坡屋面吊篮关键技术和受力验算,关键技术包括吊篮选型、锚固端固定方式、钢丝绳防磨损措施、钢丝绳防松动措施、锚固端防晃动措施、前支腿防滑落措施等,受力验算包括荷载取值、钢丝绳承载力、支架稳定性、混凝土结构承载力等。提出完整解决方案,巧妙利用结构形式提高吊篮安拆施工效率、优化整体工期,保证全过程安全可靠。实践表明,工程实施效果良好。Aiming at the construction problem of supporting electric hanging basket for slope roof,various types of construction schemes are studied and compared.Finally,the rear leg of the hanging basket is cancelled,and the rear end of the big arm for the hanging basket is directly fixed with the steel wire rope and the slope roof structure beam.The key technologies involve the selection of the hanging basket,the fixing method of the anchorage end,the anti⁃wear measures of the wire rope,the anti⁃loosening measures of the wire rope,the anti⁃sway measures of the anchorage end,and the anti⁃slipping measures of the front leg.The stress checking involves load value,wire rope bearing capacity,support stability,concrete structure bearing capacity.A complete solution is proposed,and the structural form is skillfully used to improve the efficiency of hanging basket installation and demolition construction,optimize the overall construction period,and ensure the safety and reliability of the whole process.Practice shows that the project implementation effect is good.
