塔式起重机M型附着装置计算方法

Design and Calculation Method of M-type Attachment Device of Tower Crane

当塔机距离建筑物较远时,按照《使用说明书》规定的型式安装附着杆,塔机侧向刚度较差。如采用非常规的M型四杆附着装置,可增强塔身的侧向刚度。用力法求解超静定结构轴向力,并综合考虑自重、水平风载的影响,复核杆件的结构稳定性。

When the tower crane is far away from the building,the lateral stiffness of the tower crane is poor if the attachment rod is installed according to the type specified in the operation manual.If the unconventional M-type four-bar attachment device is used,the lateral stiffness of the tower can be enhanced.The force method is used to solve the axial force of statically indeterminate structure,and the influence of self weight and horizontal wind load is comprehensively considered to check the structural stability of members.
