DETAILED DESCRIPTION

[0020] The following is a further detailed description of this application with reference to the accompanying drawings and specific implementations:

[0021] like Figure 1-Figure 4 The steel structure column docking adjustment device shown includes an upper ear plate 3, a lower ear plate 4 and a connecting device 5.

[0022] An upper lug plate 3 is welded upright to one side of the upper steel column 1, while a lower lug plate 4 is welded upright to one side of the lower steel column 2. The upper and lower lug plates 3 and 4 are vertically aligned. A first lifting hole 31 and a positioning hole 32 are vertically spaced apart along the upper edge of the upper lug plate 3. A second lifting hole 41 is provided in the lower lug plate 4. A retaining slot 42 is provided at the lower end of the lower lug plate 4, near the corner of the lower steel column 2.

[0023] The connecting device 5 includes a device body, an upper connecting assembly, a lower connecting assembly, a lifting mechanism 55 and a curved clamping claw 510.

[0024] The device body is equipped with an upper groove and a lower groove, which are distributed vertically and can be connected to form a whole groove. The upper ear plate 3 is located on the upper steel structure column 1 and extends into the upper groove. The lower ear plate 4 is located on the lower steel structure column 2 and extends into the lower groove.

[0025] The upper connection assembly includes an upper fastening assembly and a positioning member, which includes a positioning screw 53 and a positioning nut 54. The positioning screw 53 passes through the positioning holes 32 of the device body and the upper ear plate 3 and is connected to the positioning nut 54. The positioning member and the positioning hole 32 initially position the device body and the upper ear plate 3.

[0026] The upper fastening assembly includes a first bolt 51 and a second bolt 52, each located on either side of the upper slot and threadedly connected to the device body. The ends of the first and second bolts 51 and 52 extend into the upper slot, securing the upper lug 3 within the slot. The first and second bolts 51 and 52 secure the upper lug 3 while also limiting its relative position to the device body.

[0027] The lower connecting assembly includes a lower fastening assembly and a hoop 59; the hoop 59 clamps the lower ear plate 4 and the device body; a portion of the hoop 59 surrounds the device body, and the other portion is located in the slot 42, clamping the lower ear plate 4 and the device body.

[0028] The lower fastening assembly fastens the device body and the lower ear plate 4.

[0029] like Figure 4 As shown, the lower fastening assembly includes a third bolt 56, a fourth bolt 57, and a fifth bolt 58. The third and fourth bolts 56, 57 are threadedly connected to the device body and are located on at least one side of the lower slot. The ends of the third and fourth bolts 56, 57 extend into the lower slot to tighten against the lower lug plate 4 extending into the lower slot. The fifth bolt 58 is threadedly connected to the bottom of the device body and is located below the lower slot. The end of the fifth bolt 58 extends into the lower slot to tighten against the bottom of the lower lug plate 4 extending into the lower slot.

[0030] like Figure 3 As shown, curved clamping claws 510 are located on either side of the upper and lower grooves of the device body, and are used to clamp the upper and lower lug plates 3 and 4. The curved clamping claws 510 also enhance friction between the upper and lower lug plates 3 and 4, providing a more secure connection. The curved clamping claws 510 can be considered flexible clamps or elastic clips.

[0031] like Figure 3 、 Figure 4As shown, the lifting mechanism 55 includes a fixed leg, an adjusting bolt 551, a pry bar 552, and a spacer 553. The spacer 553 is positioned between the upper and lower slots, with its bottom abutting the top of the lower lug plate 4. The middle portion of the spacer 553 is hingedly connected to the pry bar 552, providing a fulcrum for the pry bar 552. The fixed leg is fixedly connected to the device body. The adjusting bolt 551 is vertically arranged and threadedly connected to the fixed leg. The lower end of the adjusting bolt 551 is connected to one end of the pry bar 552, and the other end of the pry bar 552 is positioned between the lower lug plate 4 and the upper lug plate 3. The fixed leg is located at the end of the device body facing away from the upper and lower lug plates 3 and 4.

[0032] A certain distance is left between the pry bar 552 and the upper steel structure column 1 and the lower steel structure column 2, in order to leave enough continuous welding space around the circumference of the steel structure column.

[0033] The maximum adjustable height of adjusting bolt 551 is 15 mm. The reference empirical value for weld shrinkage between upper steel structure column 1 and lower steel structure column 2 is generally 3.5 mm. The actual weld shrinkage may vary depending on factors such as material, process, and environmental conditions. Therefore, appropriate adjustments and controls are required based on actual conditions during welding operations.

[0034] The specific usage of the steel structure column docking adjustment device is as follows:

[0035] Step 1: Before each steel column section is hoisted, determine the number of connecting devices 5 required for each section. The number of adjusting devices required for each section is determined by the cross-section of the steel column. Typically, one to three adjusting devices are used for each of the four sides of the steel column 2. Insert the positioning screw 53 into the positioning hole 32 of the upper lug 3 and initially tighten the positioning nut 54 on the other side. This means that the connecting device 5 is attached to the upper lug 3 before the upper steel column 1 is hoisted, and the upper steel column 1 is hoisted along with it.

[0036] Step 2: After the upper steel structure column 1 is hoisted to contact with the lower steel structure column 2, take out the positioning screw 53, and put the hoop 59 of the connecting device 5 into the slot 42 provided on the lower ear plate 4. Then, insert the positioning screw 53 into the positioning hole 32, and initially tighten the positioning nut 54 on the other side clockwise to form a safe pre-connection.

[0037] Step 3: Preliminarily tighten the first bolt 51, the second bolt 52, the third bolt 56, the fourth bolt 57, and the fifth bolt 58 in a clockwise direction.

[0038] Step 4, tighten the fifth vertical bolt 58, rotate the third bolt 56 and the fourth bolt 57 clockwise to tighten, lock the lower ear plate 4, and firmly connect the connecting device 5 to the lower ear plate 4.

[0039] Step 5: Move the pad 553 so that it is in close contact with the top of the lower ear plate 4. Then, by turning the adjusting bolt 551, change the height of the pry bar 552 below it, so as to use the other end of the pry bar 552 to fine-tune the relative position of the upper steel structure column 1 and the lower steel structure column 2. Use a laser theodolite, steel ruler or other measuring tools to measure the relative distance between the upper steel structure column 1 and the lower steel structure column 2 so that it meets the weld shrinkage value. Then, tighten the positioning nut 54 clockwise.

[0040] Step 6: Adjust the third bolt 56 and the fourth bolt 57 clockwise to adjust the position deviation between the upper steel structure column 1 and the lower steel structure column 2.

[0041] Step 7: After the upper steel structure column 1 and the lower steel structure column 2 are spliced ​​together, loosen the adjustment bolt 551 counterclockwise, and then loosen the fifth bolt 58, the first bolt 51, the second bolt 52, the third bolt 56, and the fourth bolt 57 counterclockwise in sequence to pass through the positioning screw 53.

[0042] Step 8: Remove the connecting device 5 and weld it section by section for recycling.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be pointed out that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
