Abstract

This utility model provides a positioning and correction device for steel casings with jacks, belonging to the field of building construction technology. The device includes a base, a support frame, an adjustment mechanism, and a correction mechanism. The base is a rectangular steel plate structure with anchor bolt holes at all four corners. The support frame is fixedly installed on the upper surface of the base and consists of four columns and a crossbeam. The four columns are rectangularly distributed and fixed to the base by welding, while the crossbeam is fixed to the middle of the columns. The adjustment mechanism includes four sets of jack components. Each jack component includes a jack body, a connecting seat, and an adjusting screw. The jack body is fixed to the crossbeam via the connecting seat, and one end of the adjusting screw is fixedly connected to the jack piston rod. This utility model can solve the problem that existing steel casings cannot be corrected in a timely manner after tilting.
