核心筒外钢框架结构大型塔吊附着装置应用

Application Research of Large Tower Crane Attachment Device for Steel Frame Core Wall Hybrid Structure

结合核心筒钢框架工程项目施工实例,详细介绍了在核心筒外钢框架结构施工过程中大型塔吊附着装置的应用,提出了大型塔吊附着装置的选型、设计及施工要求。通过将塔吊附着装置设置在加固处理后的外钢框架上,使外钢框架满足塔吊附着要求。工程实践结果表明,采用该技术具有良好的社会经济效益,对类似工程施工具有借鉴作用。

Combined with the construction example of steel frame core wall hybrid structure,the application of attachment device of large tower crane in the construction of steel frame core wall hybrid structure is introduced in detail. The selection, design and construction requirements of attachment device for large tower crane are proposed.By installing the attachment device of tower crane on the reinforced external steel frame, the external steel frame can meet the attachment requirements of tower crane. Engineering practice results show that the technology has good social and economic benefits, and it can be used for references in similar projects.
