Novel prestressed joist column replacing device
The invention relates to the technical field of underpinning treatment devices of reinforced concrete columns, in particular to a novel prestressed joist column replacing device which comprises a reinforced concrete column, an original roof beam plate and a box, an underpinning girder is fixedly mounted outside the box, and a high-strength bolt is in threaded connection with the outside of the underpinning girder. According to the invention, firstly, the underpinning girder and the box body are close to the damaged reinforced concrete column body, then a certain distance is reserved between the underpinning girder and the original roof beam plate, the original roof beam plate is in threaded connection with the high-strength bolt, the box body is internally and rotatably connected with a threaded screw rod, and the outer part of the threaded screw rod is in threaded connection with a working block. And the high-strength bolts and the bolt holes are utilized to hang the original roof beam plate, the high-strength bolts continue to be tightened to apply prestress, the working block controls movement, the second hydraulic cylinder controls the working depth of the drill bit, and the second motor controls the drill bit to rotate, so that the working cost of the device is controlled and reduced, and the working efficiency of the device is effectively improved.
本发明涉及钢筋混凝土柱体的托换处理装置技术领域，尤其涉及一种新型预应力托梁换柱装置，包括装置钢筋混凝土柱、原有屋盖梁板和箱体，箱体外部固定安装有托换大梁，托换大梁外部螺纹连接有高强螺栓，原有屋盖梁板与高强螺栓之间螺纹连接，箱体内部转动连接有螺纹螺杆，螺纹螺杆外部螺纹连接有工作块，本发明中，首先将托换大梁和箱体靠近受损钢筋混凝土柱体，然后在托换大梁与原有屋盖梁板之间预留一定间距，利用高强螺栓与螺栓孔进而将原有屋盖梁板吊住，继续拧紧高强螺栓施加预应力，工作块控制移动，第二液压缸控制钻头的作业深度，第二电机控制钻头旋转，从而控制降低了装置的作业成本，有效提升了装置的工作效率。
