[0022] The application further discloses a quick calibration steel column installation fixing construction method, which comprises the following steps.

[0023] S1: when the H-shaped or cross-shaped steel column is processed, two holes are symmetrically reserved at the column top and the column bottom at a distance of 100 mm from the short side of the wing plate, and the holes are used for connecting high-strength bolts;

[0035] Working principle of this invention: This invention can be applied to the hoisting and connection of H-shaped and cross-shaped steel columns. During the hoisting and connection of steel columns, this invention can provide rapid and accurate guidance and positioning, eliminate the need for ear plates, and monitor the verticality of the steel column. When using this invention, two symmetrical holes need to be made at 100mm from the short side of the steel column wing plate. The fasteners are used to fix the steel column flanges. First, the lower bolt connection holes are connected to the lower section of the steel column using high-strength bolts. Then, guide components are fixed to the web of the steel column using magnetic plates, forming a hoisting fixing groove. This provides precise guidance and positioning during the hoisting of the upper section of the steel column. After the upper section of the steel column is hoisted into place, the bolt connection holes on the fasteners are connected to the upper section of the steel column using high-strength bolts, forming a temporary fixing device. This replaces the ear plates and connecting plates for temporary fixing, eliminating the need for ear plate construction. After the upper and lower sections of the steel column are connected and fixed, during steel structure alignment, a verticality detector can detect the verticality of the steel column, quickly locating the tilt position and shortening the measurement time. After the steel column alignment and welding are completed, the fasteners and guide components are removed.

Using the slot to fix the steel column can effectively reduce the horizontal swaying and torsion generated during the hoisting of the steel column, greatly improve the hoisting accuracy of the steel column, and effectively reduce the adjustment and calibration time of the steel column, thereby improving construction efficiency.

[0038] 2. This invention can replace traditional ear plates and connecting plates, and serve as a temporary support after the steel column is hoisted and unhooked, reducing steel input, saving costs, and improving the appearance quality of the steel column.

[0039] 3. This invention device has a real-time verticality measurement function. After the steel column is hoisted into place, the verticality of the steel column can be monitored in real time, the tilt position of the steel column can be quickly detected, the measurement and positioning time can be greatly shortened, and the construction efficiency can be improved.

[0040] 4. The magnetic plate uses sintered neodymium iron boron magnets as the magnetic force source, which can provide an attraction force of about 15~20KG, which can effectively counteract the horizontal swaying and torsion generated during the hoisting of steel columns;

[0041] 5. The magnetic board uses sintered neodymium iron boron magnets as the magnetic force source, which can be used effectively for a long time, and its magnetic force can last for about 30 years.

[0042] 6. This invention device can be reused;

[0043] 7. The guide component's vertical projection is shaped like the number 7. The second grip handle and the magnetic area can form a lever. When removing it using the lever principle, approximately 5 kg of force is required to remove it.

[0044] 7、The device is easy to operate, has low influence on work efficiency, is light in weight, and can be operated by one worker, the device does not need power, is convenient to assemble and disassemble, and can be independently operated by one adult male;

[0045] 8、The device can form an arc-shaped hoisting positioning clamping groove, the arc-shaped opening can guide the upper section steel structure column to smoothly enter the hoisting positioning clamping groove, improve construction efficiency, and reduce the collision between the steel structure column and the clamping groove;

[0046] 9、The upper connecting bolt hole and the lower connecting bolt hole of the fixing member have an arc-shaped protrusion, the distance from the bolt hole to the edge of the first structure plate is increased, and the structural strength of the fixing member is improved.

[0047] 10、The first and second grip handles and the first and second resistance increasing balls can effectively prevent the component from being dropped during installation and disassembly, and improve construction safety. BRIEF DESCRIPTION OF DRAWINGS
