Permanent tower cable-stayed buckling and hanging device for steel beam pushing and using method of permanent tower cable-stayed buckling and hanging device
The invention discloses a permanent tower cable-stayed buckling and hanging device for steel beam pushing and a using method thereof, and belongs to the field of bridge construction.The permanent tower cable-stayed buckling and hanging device comprises a bearing mechanism arranged on a beam body structure, and the bearing mechanism and the beam body structure are connected together through at least two connecting assemblies; the beam body structure comprises a guide beam and a steel truss girder connected with the guide beam, and one ends of the at least two connecting assemblies are connected with the guide beam and the steel truss girder correspondingly. According to the permanent tower cable-stayed buckling and hanging device for steel beam pushing and the using method of the permanent tower cable-stayed buckling and hanging device for steel beam pushing and the using method of the permanent tower cable-stayed buckling and hanging device, the downwarping amount of the front end can be reduced, the length of the guide beam is shortened, and the pier climbing difficulty is lowered; in the pushing process, the rear anchor cable is locked, the center hole jack can adjust the tension of the anchor cable according to the stress condition of a beam body structure, the stress states of a chord member and a web member under a pushing fulcrum in a large cantilever state can be greatly improved, the stress peak value is reduced, and the stress safety of a permanent structure is ensured.
本发明公开了一种用于钢梁顶推的永久塔斜拉扣挂装置及其使用方法，属于桥梁施工领域，其包括设置在梁体结构上的承载机构，所述承载机构与梁体机构之间通过至少两连接组件连接在一起，所述梁体结构包括导梁与其连接设置的钢桁梁，至少两所述连接组件的一端分别与所述导梁和钢桁梁连接本发明的用于钢梁顶推的永久塔斜拉扣挂装置及其使用方法，可减少前端下挠量，缩减导梁长度，降低上墩难度；在顶推过程中，后锚索进行锁定，穿心千斤顶可根据梁体结构受力情况对锚索的张力进行调整，能大幅改善大悬臂状态顶推支点下的弦杆及腹杆受力状态，降低应力峰值，确保了永久结构的受力安全。
