摘　　要：为解决因工程结构设计特点、塔吊型号、平面布置、附着要求等多种因素制约,造成一些建筑需利用薄弱边缘构件作为塔吊附着点,但由于附着面较小,无法满足塔吊附着的受力要求的问题,结合工程实际,介绍了小截面边缘构件的塔吊附着施工技术和安全控制重点。通过优化附着支座的方式,增加附着点受力截面使之达到设计使用要求,可为类似项目提供参考。To solve the problem that some buildings need to use weak edge components as the attachment point of tower crane due to the constraints of engineering structure design characteristics,tower crane model,plane layout,attachment requirements and other factors,but the attachment surface is small,which cannot meet the stress requirements of tower crane attachment,combined with engineering practice,the tower crane attachment construction technology and safety control key points of small section edge components are introduced.By optimizing the way of attachment support and increasing the stress section of the attachment point,the design requirements can be met accordingly,which can provide a reference for similar projects.

关 键 词：约束边缘构件 塔吊附墙 小附着面 安全控制
