When the upper steel frame column 11 is lifted by a crane and connected to the lower steel frame column 1, the upper steel frame column 11 is initially limited by the mounting members 2; top plates 3 are symmetrically arranged on both sides of the upper steel frame column 11, and one end of the top plate 3 can be rotatably adjusted to adjust the force point during adjustment; rotating members 4 are symmetrically arranged on both sides of the lower steel frame column 1 and the upper steel frame column 11 to adjust the placement position of the top plate 3, and the rotating member 4 comprises a support frame 41 arranged on both sides of the lower steel frame column 1 and the upper steel frame column 11, and the surface of the support frame 41 is rotatably connected with a rotating shaft 42 through a bearing, and the rotating member 41 is rotatably connected to the lower steel frame column 1 and the upper steel frame column 11. A cross slot 43 is provided at one end of the shaft 42, and a second tension spring 44 is rotatably connected to the interior of the cross slot 43 through a pin shaft. A cross block 45 is fixed to the end of the second tension spring 44, and the cross block 45 is slidably connected to the cross slot 43. A pulling plate 46 is installed at one end of the cross block 45, and a plug rod 47 is fixedly connected to one side of the pulling plate 46, and a ball 48 is embedded and installed at one end of the plug rod 47. A limiting member is installed on the surface of the support frame 41 on one side of the pulling plate 46, and the limiting member includes a positioning plate 49 fixed on the surface of the support frame 41, and two positioning grooves 491 are provided on one side of the positioning plate 49. A sliding groove 492 is also provided on the surface of the positioning plate 49, wherein the two positioning grooves 491 are respectively arranged at 90° and 180° counterclockwise on the surface of the positioning plate 49, and the sliding groove 492 is in an arc shape.

[0035] In the prior art, after the steel frame columns with extra-large cross-sections are installed and constructed, vertical lifting equipment is used to lift the steel frame columns to the working surface, and then the angle and horizontal position are adjusted by hitting with a crowbar or a hammer. However, this method is not only slow in construction operation and high in labor intensity, but also easy to damage the paint on the outer wall of the steel frame column or scratch and deform the surface during the adjustment process. At the construction site, the lifting machinery and equipment used to lift the frame column needs to maintain the lifting operation limit operation of the upper steel frame column 11, which takes up a lot of mechanical equipment time, resulting in low work efficiency at the construction site and serious waste of shifts.

[0036] Therefore, in the present scheme, when the lifting machinery lifts the upper steel frame column 11 and then docks and installs the top of the lower steel frame column 1, the upper steel frame column 11 and the lower steel frame column 1 can be initially limited by the provided mounting parts 2. In this way, in the subsequent adjustment process, the lifting machinery used to lift the upper steel frame column 11 can be removed, thereby relieving the occupation time of the lifting machinery and improving the utilization rate of the shift. In the adjustment stage, the adjustment components are installed on both sides of the lower steel frame column 1. When the rotating member 4 rotates 90° counterclockwise, the top plate 3 is driven to lift up by the driving member 5. In this way, the verticality of the upper steel frame column 11 can be adjusted as needed. When the rotating member 4 rotates 180° counterclockwise, the top plate 3 is driven to rotate synchronously. The two top plates 3 are symmetrically arranged. When the top plate 3 contacts the outer walls on both sides of the upper steel frame column 11, a torsional force is applied, thereby realizing the adjustment of the horizontal angle of the upper steel frame column 11.

[0037] In specific operation, when it is necessary to adjust the vertical angle, the pulling plate 46 is manually pulled, and the cross block 45 slides on the cross groove 43, and then rotates 90 degrees counterclockwise, so that one end of the insertion rod 47 corresponds to the positioning groove 491, and the insertion rod 47 is inserted into one of the positioning grooves 491 under the elastic rebound of the second tension spring 44. In this way, the placement position of the top plate 3 is adjusted, and the top plate 3 can move up and down to adjust the verticality of the upper steel frame column 11. When it is necessary to adjust the horizontal angle, the pulling plate 46 is manually pulled to make the insertion rod 47 move from one of the positioning grooves 491. The top plate 3 is lifted up under the drive of the driving member 5, and the two symmetrically arranged top plates 3 contact the outer wall of the upper steel frame column 11 to apply a torsional force, thereby realizing the adjustment of the horizontal angle of the upper steel frame column 11, wherein the setting of the ball 48 facilitates the insertion rod 47 to slide better in the sliding groove 492.

[0038] In a preferred embodiment, referring to Figure 1 The mounting member 2 includes ear plates 20 symmetrically welded to the two side walls of the lower steel frame column 1 and the upper steel frame column 11, and a through hole 21 is opened on the surface of the ear plate 20. The aperture size of the through hole 21 is gradually distributed. The ear plate 20 at the joint of the lower steel frame column 1 and the upper steel frame column 11 is provided with a limit plate 22 through an adjusting bolt 24. The surface of the limit plate 22 is provided with a mounting hole 23. The outer walls of both sides of the upper steel frame column 11 are welded with a triangular force frame 25.

[0039] Among them, the ear plate 20 arranged on the top side wall of the upper steel frame column 11 is convenient for the lifting machinery to hang the hook in the through hole 21. After the upper steel frame column 11 is lifted, the lower steel frame column 1 is docked and installed. At this time, through the setting of the limit plate 22 and the adjusting bolt 24, it is convenient to initially limit the lower steel frame column 1 and the upper steel frame column 11. The diameter of the adjusting bolt 24 is smaller than the installation hole 23 and the through hole 21. When the adjusting bolt 24 is screwed, it is in a loose state, but will not fall off. The through hole 21 is gradually changed. The setting of the aperture makes it convenient to insert the adjusting bolt 24 into the through hole 21 of different apertures for more precise locking and limiting after the upper steel frame column 11 is adjusted vertically or horizontally. Through this structural design, the occupation time of the lifting machinery is relieved, and at the same time, the subsequent fine adjustment of the angle of the upper steel frame column 11 is not affected. It is convenient and quick to use. The setting of the triangular force frame 25 makes it convenient to increase the support points of the side wall of the upper steel frame column 11, so that the top plate 3 can contact the triangular force frame 25 during the jacking operation to adjust the upper steel frame column 11 vertically.

[0040] In a preferred embodiment, referring to Figure 4 and Figure 5 The top plate 3 includes a groove 31 opened on one side of the top plate 3, and a first tension spring 32 is rotatably connected to the inside of the groove 31 through a pin shaft. A protruding plate 35 is fixed to one end of the first tension spring 32, and a plug plate 34 is fixed to one side of the protruding plate 35. The plug plate 34 is slidably connected in the slot 33, and the slot 33 is opened on one side surface of the top plate 3.

[0041] When the upper steel frame column 11 is adjusted horizontally, the top plate 3 is in a vertical state with the side wall of the upper steel frame column 11 by rotation. The staff manually pulls the raised plate 35 to separate from one end of the top plate 3, and then rotates the raised plate 35 180 degrees. The elastic pullback of the first tension spring 32 causes the plug plate 34 on one side of the raised plate 35 to be inserted into the slot 33, and the raised plate 35 is limited. At this time, the bottom of the raised plate 35 is on the same horizontal plane as the top plate 3, and the top of the raised plate 35 is The surface is higher than the top surface of the top plate 3, so that when the two top plates 3 contact the two side walls of the upper steel frame column 11, a rotational force will be formed to achieve the horizontal angle adjustment of the upper steel frame column 11. When the verticality adjustment operation of the top plate 3 is performed, through the above steps, the raised plate 35 is flipped again so that the bottom surface of the raised plate 35 faces upward, so that the top surface of the raised plate 35 is flush with the top surface of the top plate 3, and the upper and lower side surfaces of the raised plate 35 and the top plate 3 are both provided with anti-slip rubber material.

[0042] In a preferred embodiment, referring to Figure 7A driving member 5 is provided on the support frame 41 , and the driving member 5 includes a mounting seat 51 fixedly mounted on the rotating shaft 42 , a jack 52 is installed on the top of the mounting seat 51 , and an output end of the jack 52 is fixed to the top plate 3 .

[0043] During the adjustment operation, the top plate 3 can be driven to move by starting the jack 52, and then the upper steel frame column 11 can be finely adjusted. In a preferred embodiment, the jack 52 can be replaced by an electric hydraulic rod drive to facilitate the synchronous movement of the two top plates 3.

[0044] In a preferred embodiment, referring to Figure 7 , Figure 8 and Fig. 9 A gas collecting assembly 6 is provided on the mounting seat 51, and the gas collecting assembly 6 includes a connecting plate 61 fixed to one side of the mounting seat 51, and a buckle 62 is installed at one end of the bottom of the connecting plate 61. A connecting cylinder 63 is rotatably connected to one side of the support frame 41 through a pin shaft, and a piston 64 is slidably connected inside the connecting cylinder 63. A movable rod 65 is fixed to one side of the piston 64, and a connecting rod 66 is fixed to one end of the movable rod 65. One end of the connecting cylinder 63 is connected to an air inlet pipe 67, and a one-way valve is provided on the air inlet pipe 67. One end of the connecting cylinder 63 is connected to an air outlet pipe 68, and a nozzle 69 is fixed to the end of the air outlet pipe 68. A one-way valve is provided between the air outlet pipe 68 and the connecting cylinder 63. An inclined surface is provided on the top of the support frame 41. When the connecting plate 61 rotates and does not contact the support frame 41, a T-shaped rod 8 is installed on one side of the support frame 41, and the air outlet pipe 68 is wrapped around the T-shaped rod 8.

[0045] When the pulling plate 46 is manually pulled to separate the insertion rod 47 from the positioning plate 49 and then rotated clockwise, one end of the insertion rod 47 slides inside the sliding groove 492, hanging the buckle 62 on the connecting rod 66 and connecting it to the movable rod 65. The staff can pull the driving member 5 to rotate reciprocally. At this time, the air inlet pipe 67 draws in external air and then sprays it out through the nozzle 69 at one end of the air outlet pipe 68. The staff holding the nozzle 69 can blow and clean foreign matter in the gap installed during the docking installation of the upper steel frame column 11, thereby keeping the docking installation position clean and tidy, and facilitating subsequent welding and fixing operations. Combined with the overall solution, the process of adjusting the angle of the upper steel frame column 11 also has the effect of blowing and cleaning, which also avoids the foreign matter in the joint from affecting the docking installation of the lower steel frame column 1 and the upper steel frame column 11, thereby reducing the probability of errors during the docking installation process.

[0046] In a preferred embodiment, referring to Figure 2 , Figure 3 and Figure 4A fixing member 7 is provided at the bottom of the two support frames 41, and the fixing member 7 includes a first fixing frame 71 fixed to the bottom of the two support frames 41, a second fixing frame 73 is provided on one side of the first fixing frame 71, and a rubber layer 72 is fixed to one side of the first fixing frame 71 and the second fixing frame 73, and mounting blocks 74 are provided at the ends of the first fixing frame 71 and the second fixing frame 73. The first fixing frame 71 and the second fixing frame 73 are fixed to the outer wall of the lower steel frame column 1 by bolts on the mounting block 74, and a steel plate 91 is fixed on the top of the lower steel frame column 1, and a casting hole 92 is opened on the surface of the steel plate 91, and a limiting groove 94 is opened on the surface of the steel plate 91, and a positioning block 93 is welded to the inner wall of the bottom of the upper steel frame column 11.

[0047] During installation, the first fixing frame 71 and the second fixing frame 73 are clamped on the top outer wall of the lower steel frame column 1, and then the bolts are installed on the mounting block 74 to fix it in position, and the adjusting components are installed on both sides of the lower steel frame column 1 for easy disassembly and assembly. During docking installation, the positioning block 93 is correspondingly clamped in the limiting groove 94 to facilitate the positioning operation of the upper steel frame column 11, wherein the width of the limiting groove 94 is greater than the width of the positioning block 93, which is convenient for the preliminary positioning of the upper steel frame column 11, and the casting hole 92 is convenient for filling and casting other fillers in the lower steel frame column 1 and the upper steel frame column 11 to improve the structural strength of the frame column.
