Counter-force structure for replacing and installing permanent suspender of suspension bridge
The invention discloses a counter-force structure for replacing and installing a permanent suspender of a suspension bridge, which comprises a transversely arranged toggle clip anchor plate, a pressure-bearing steel beam supported on the top surface of the toggle clip anchor plate along the longitudinal direction, a jack mounted on the pressure-bearing steel beam, a cushion block arranged on the top surface of the jack, and a counter-force anchor beam transversely arranged below the toggle clip anchor plate, the top face of the counter-force anchor beam is located below the bottom face of the anchor box at the lowermost end of the temporary sling structure, the bottom of the finish-rolled threaded steel bar penetrates through the counter-force anchor beam and lifts the counter-force anchor beam, the finish-rolled threaded steel bar vertically extends upwards and penetrates through the pressure-bearing steel beam, the jack and the cushion block, and the part, located above the cushion block, of the finish-rolled threaded steel bar is sleeved with a first locking nut in a threaded mode. And a plurality of permanent suspenders penetrate through the toggle clip anchor plate and lift the toggle clip anchor plate. By means of the counter-force structure, downward extrusion force can be achieved on the permanent suspender, meanwhile, the standby lifting point can be lifted upwards, a tiny gap is formed between the pin shaft and the stress face of the pin hole, and therefore the pin shaft can be pulled out or inserted conveniently, and the permanent suspender can be disassembled or assembled conveniently.
本发明公开了一种用于悬索桥更换、安装永久吊杆的反力结构，包括有横向设置的夹扣锚板，夹扣锚板顶面沿纵向支撑设置有承压钢梁，承压钢梁上安装有千斤顶，千斤顶顶面设置有垫块，夹扣锚板下方横向设置有反力锚梁，反力锚梁的顶面位于临时吊索结构的最下端锚箱底面下方，精轧螺纹钢筋底部穿过反力锚梁并将其提拉住，精轧螺纹钢筋竖直向上伸出并穿过承压钢梁、千斤顶和垫块，位于垫块上方的精轧螺纹钢筋上螺纹套接有第一锁紧螺母，多根永久吊杆穿过夹扣锚板并将其提拉住。通过该反力结构可以对永久吊杆实现向下的挤压力，同时又可以向上提拉住备用吊点，使得销轴与销孔的受力面之间出现微小的间隙，从而方便拔出或穿入销轴，便于永久吊杆的拆卸或安装。
