The invention discloses a static lifting device for dismantling a continuous bridge body in a whole span mode and a construction method, the static lifting device comprises a reaction frame (1), a lifting device (2) is arranged on the reaction frame (1), and the lifting device (2) is connected with a bearing device (5) through a steel strand (3). The reaction frame is integrally designed into a plurality of parts and is convenient to disassemble and transport, onsite connection is realized through bolts and profile steel, mounting and dismounting are simple rapid, bearing is stable, the gravity of the a heavy bridge can be born via a low structure cost, and when the method is used to dismount the beam, the equipment, material and labor cost is only about 1/3 of the original mechanical dismounting cost, and the construction cost is greatly reduced.
本发明公开了一种整跨拆除连续桥梁梁体的静力提吊装置及施工方法,包括反力架(1),反力架(1)上设有提升设备(2),提升设备(2)通过钢绞线(3)连接承托装置(5)。反力架整体设计为几个部件,方便拆卸运输,然后在现场用螺栓、型钢等进行连接,安装拆除简便快捷,受力稳定,能够以较低的结构成本承受大重量桥梁梁体的重力,采用本发明方法拆除梁体,设备、材料及人工费用仅为原设计机械拆除费的1\3左右,大大节约了施工成本。
