Reinforced concrete column underpinning device

YUAN KAIJUN / JIANG SICHENG / JIANG TAO / GE ZIZHENG

The invention discloses a reinforced concrete column underpinning device, and relates to the technical field of reinforced concrete (RC) column underpinning. Comprising a first underpinning plate, a height adjusting mechanism is arranged in the first underpinning plate, the height adjusting mechanism comprises a first motor arranged in the first underpinning plate, a sliding groove is formed in the first motor, a sliding block is slidably connected into the sliding groove, a first threaded rod is arranged at the output end of the first motor, and a threaded cylinder is in threaded connection with the exterior of the first threaded rod; the side, away from the first motor, of the first threaded rod is fixedly connected with a second underpinning plate, and the height adjusting mechanism enables the second underpinning plate to be converted into a lifting motion state from a static state. The supporting height of the device can be automatically adjusted according to actual engineering conditions, operation is easy, construction is convenient, and the device can be suitable for construction scenes of most reinforcement and transformation projects. And for concrete columns with different section sizes, pre-tightening force can be applied to a new column template by changing the distance between the force application plates, so that the construction efficiency is improved.

本发明公开了一种钢筋混凝土柱托换装置，涉及钢筋混凝土(RC)柱托换技术领域。包括第一托换板，第一托换板内部设置有高度调节机构，高度调节机构包括第一托换板内部设置的第一电机，第一电机内部开设有滑槽，滑槽内部滑动连接有滑块，第一电机的输出端设置有第一螺纹杆，第一螺纹杆外部螺纹连接有螺纹筒，第一螺纹杆远离第一电机的一侧固定连接有第二托换板，高度调节机构使得第二托换板由静止状态转变为升降运动状态。本发明中，可根据工程实际情况自动调节装置支撑高度，操作简单施工方便，可适用于大多数加固改造工程的施工场景。对于不同截面尺寸的混凝土柱，可通过改变施力板之间的距离，对新柱模板施加预紧力，提高施工效率。
