Construction method for dismantling large-span prestress cast-in-place box girder support
The invention discloses a dismantling construction method for a large-span prestress cast-in-place box girder support, and particularly relates to the field of cast-in-place box girders.The dismantling construction method comprises four adjusting assemblies, the bottoms of the four adjusting assemblies are jointly and fixedly connected with a traction assembly, and a supporting assembly is installed on the upper surface of the traction assembly; and monitoring assemblies are installed on the outer side walls of the adjusting assemblies, and the four adjusting assemblies are symmetrically located in front of and behind the traction assembly. Four brackets are fixed to the surface of a cast-in-place box girder body, an adjusting disc is rotated, the position of a supporting assembly is adjusted, a supporting frame is in butt joint with a positioning column, then a traction rope sequentially penetrates through a supporting disc, a supporting ring, a limiting pulley, a limiting hole and a circular ring, and the traction rope is slowly released through a winch; at the moment, the support body slowly moves downwards under the action of gravity, the traction ropes are integrated on one winch through the supporting assembly, the four traction ropes can be synchronously wound and unwound, and it is guaranteed that the support body is horizontal when disassembled.
本发明公开了一种用于大跨度预应力现浇箱梁支架拆除施工方法，具体涉及现浇箱梁领域，包括四个调节组件，四个所述调节组件的底部共同固定连接有牵引组件，所述牵引组件的上表面安装有支撑组件，所述调节组件的外侧壁安装有监测组件，四个所述调节组件对称位于牵引组件的前方和后方。本发明通过将四个托架固定在现浇箱梁主体的表面，转动调节盘，对支撑组件的位置进行调整，使支撑架与定位柱对接，然后将牵引绳依次穿过支撑盘、支撑环、限位滑轮、限位孔和圆环，通过卷扬机慢慢放出牵引绳，此时支架主体在重力的作用下缓慢向下移动，通过支撑组件将牵引绳集成在一个卷扬机上，实现了可以使四个牵引绳同步收放，以保证支架主体拆卸时的水平。
