Technical Field

[0001] The present invention belongs to the technical field of construction engineering, and in particular relates to a steel column butt support frame and a steel column butt joint construction method using the support frame. Background Technique

[0002] When installing high-rise steel structures, it is often necessary to butt-connect steel columns, and the quality of the steel column butt joint directly affects the quality and safety performance of the entire structure.

[0003] At present, during the relative assembly of two steel columns, it is necessary to use a tower crane to continuously adjust the load on the upper steel column. The adjustment force of the tower crane is unstable, which is likely to cause the upper steel column to shake during the erection process. This not only causes inconvenience in actual installation, but also poses certain safety hazards. It is very easy to cause great safety problems if the shaking hits the staff.

[0004] Therefore, we propose a steel column butt support frame and a steel column butt joint construction method using the support frame to solve the above problems. Summary of the Invention

Two adjusting screw rods are symmetrically and fixedly connected to the lower end of the cross plate, and the adjusting screw rods are threadedly sleeved inside the rotating screw cylinders.

[0007] In the above-mentioned steel column butt support frame, a plurality of insertion columns are fixedly connected to the inner wall of the U-shaped positioning plate. Insertion holes that are matched and inserted with the insertion columns are opened on the outer walls of the upper steel column and the lower steel column. An electromagnetic adsorption block is also fixedly embedded in the inner wall of the U-shaped positioning plate.

[0008] In the above-mentioned steel column butt support frame, a T-shaped clamping block is fixedly connected to the outer wall of the extension plate. T-shaped clamping grooves that are matched and clamped with the T-shaped clamping block are opened on both side walls of the U-shaped locking plate.

[0016] S1. By using the matching insertion of the insertion column and the insertion hole, the U-shaped positioning plate is quickly connected to the outside of the upper steel column and the lower steel column. Then, power is supplied to the electromagnetic adsorption block, so that the electromagnetic adsorption block generates magnetism and stably adsorbs to the outside of the upper steel column and the lower steel column.

[0017] S2. Start the double-shaft motor. The double-shaft motor drives the two active bevel gears to rotate.

When assembling between the upper steel column and the lower steel column, the double-shaft motor is started. The double-shaft motor drives two driving bevel gears to rotate. Through the meshing action of the driving bevel gear and the driven bevel gear, two rotating screw barrels are driven to rotate synchronously. Through the threaded socket connection of the rotating screw barrel and the adjusting screw rod, two adjusting screw rods are driven to push the cross plate to drive the upper steel column to move up and down, realizing stable assembly with the lower steel column. There is no need for the tower crane to always load and adjust, the adjustment accuracy of the assembly is higher, and the use safety is better.
