Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building engineering, in particular to a novel detachable steel column correction device. Background Art
[0002] Steel-concrete composite structure is a new type of structure made of two materials with different properties, steel and concrete. It is a reasonable combination of steel and concrete, giving full play to the advantages of steel's high tensile strength and good plasticity and concrete's good compressive performance, and making up for their respective shortcomings.
[0003] The correction method of the verticality of the steel column after hoisting is that when the deviation value is small, it is generally corrected by hammering with a steel chisel or a wedge; when the verticality deviation is large, it is generally corrected by a hydraulic jack correction method, a steel pipe support rod inclined jacking method, and a wind rope correction method. The traditional hydraulic jack correction method generally temporarily welds four jacking plates perpendicular to the ground plane on the outer walls around the steel column, and then arranges the jack between the jacking plate and the ground. The jacking of the jack on one side is used to correct the verticality of the steel column. After the correction work is completed, the temporarily welded jacking plate is cut off. However, in the process of correction, many projects use traditional jacking plates welded on the outer walls around the steel column for jacking correction, which has certain requirements for the on-site welding quality of the jacking plates; because the welding is cut off after the outer wall is lifted, there is a certain damage to the steel column base material; the operation is relatively cumbersome. If a round tube column is encountered, the jacking plate needs to be cut and welded, resulting in a long construction time, low efficiency, and there is a situation where it cannot be recycled.

[0006] Furthermore, the upper end of the vertical reinforcement rod is connected to a triangular reinforcement frame.
[0007] Furthermore, the upper clamping plate is arranged horizontally, and the lower clamping plate is arranged horizontally at an angle inclined downward, so that the upper clamping plate and the lower clamping plate can be used to clamp and install the steel column base plate.

[0009] Furthermore, the vertical reinforcement rod is vertically fixed to the upper surface of the upper clamping plate.
[0010] Furthermore, the inner sides of the upper clamping plate and the lower clamping plate are both configured as frosted surfaces to increase the friction coefficient between the inner side surfaces and the column base plate.
[0011] Furthermore, the lifting device adopts a jack.
[0012] Furthermore, the jacking plate, the upper clamping plate and the lower clamping plate can all be made of long strips of steel bars or steel plates.
