塔式起重机附着装置通常安装在建筑物的框架结构上。排架结构的强度和稳定性相对较差,一般不适宜安装附着装置。本工程受结构条件所限,塔式起重机的最上面一套附着装置安装在排架结构上。本文介绍了该排架结构的加固方案和验算方法。
Tower crane attachments are usually installed on the frame structure of a building. Rack structure strength and stability is relatively poor, generally not suitable for installation of attachment. The project is subject to the structural conditions, the top of a tower crane attachment installed in the rack structure. This paper introduces the reinforcement scheme and checking method of the rack structure.
