摘　　要：塔身是塔式起重机的主要部件,由标准节通过高强度螺栓连接而成,对起重机的稳固性、安全性起决定性作用。对塔式起重机塔身连接中存在的高强度螺栓重复使用,高强度螺栓安装不符合要求,高强度螺栓预紧力不符合设计值要求等问题进行了分析,并提出应对措施。The tower body is the main component of the tower crane,which is connected by standard sections through high-strength bolts,which play a decisive role in the stability and safety of the crane.The issues existing in the connection of the tower crane body,such as repeated use of high-strength bolt,the installation of high-strength bolt does not meet the requirements,and the pre-tightening force of the high-strength bolt does not meet the required design value were analyzed,and the countermeasures were proposed.
