[0054] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0055] Reference Figures 1 to 12 A support column according to an embodiment of the present invention includes a circular tube column unit 100, a plurality of first component units 200, a plurality of second component units 300 and a plurality of third component units 400, all of which are installed on the outer periphery of the circular tube column unit 100.

[0056] In some embodiments of the present invention, four of each of the first component unit 200, second component unit 300, and third component unit 400 are installed. The four first component units 200 are first assembled individually and then welded to the outer periphery of the cylindrical tube unit at even intervals. The four second component units 300 and the four third component units 400 are welded between pairs of adjacent first component units 200. A narrow groove with an opening on one side is formed between pairs of adjacent first component units 200. Multiple second component units 300 are respectively installed at the first end of multiple narrow grooves, and multiple third component units 400 are respectively installed at the second end of multiple narrow grooves, partially covering the second component units 300. The multiple first component units 200 and multiple second component units 300 form a regular octagon on the outer periphery of the first end of the cylindrical tube unit 100, and the multiple first component units 200 and multiple third component units 400 form a square on the second end of the cylindrical tube unit 100. The support column is decomposed into multiple component units. The support column is manufactured by assembling each component unit and then assembling them sequentially. This approach improves component assembly efficiency and effectively shortens the manufacturing period while meeting design requirements.

[0057] In some embodiments of the present invention, the circular tube column unit 100 is provided with grouting holes 110; see reference Figure 2 As shown, the circular tube column unit 100 has multiple grouting holes 110 spaced along its length. The diameter of the grouting holes 110 can be designed according to actual needs. In order to ensure that the structural stability of the circular tube column unit 100 is not affected, a reinforcing plate 111 is provided on the outer periphery of some grouting holes 110. The weld of the reinforcing plate 111 is required to be full penetration of the first grade and is welded with a backing. The circular tube column unit 100 is assembled by segmented manufacturing. The circular tube column unit 100 is also provided with plug welding holes 180. The internal part of the circular tube column unit 100 is also provided with node partition plates 120, which divide the interior of the cylindrical tube into multiple segments. The two ends of the circular tube column unit 100 are respectively provided with a column top sealing plate 160 and a column bottom partition plate 170.

[0058] It is important to understand that the circular tube column unit 100 is manufactured using a process of segmented cutting, segmented rolling, and tube assembly. The manufacturing steps are as follows:

[0059] Step 1: Cut multiple steel plates, and pre-cut grouting holes 110 on each of the steel plates; before cutting the steel plates, unfold the positions of the grouting holes 110 on the steel plate plane, and cut the grouting holes 110 using CNC flame cutting method to avoid secondary cutting on the pipe body and ensure the overall appearance effect after rolling.

[0060] Step 2: Roll multiple steel plates into cylinders; make plug welding holes 180 on the cylinders. The size of the plug welding holes 180 should be slightly larger than the design size to ensure smooth assembly of subsequent components.

[0061] Step 3: Connect multiple cylinders into a single cylindrical tube; the cylinders are connected using an internal welding and external root cleaning method, and the weld is required to be full penetration of Grade I; the connection between the cylinders is strictly made in accordance with the relevant provisions of the steel structure quality acceptance standard, and the weld of the cylinder joint is required to be full penetration of Grade I around the circumference, using an internal welding and external root cleaning method to ensure the forming effect after the cylinder joint, while a certain allowance should be reserved for the total length; the inner and outer walls of the cylindrical tube column need to be marked with eight equal denominators as the reference lines for the subsequent assembly of each unit;

[0062] It's worth noting that you can also pop up denominators for six or ten equal parts as needed;

[0063] Step 4: Install multiple node partition plates 120 inside the cylindrical tube. The node partition plates 120 are installed by retracting from the middle of the cylindrical tube towards both ends. Considering the limited internal welding space of the cylindrical tube column unit 100, the node partition plates 120 are preferably welded using backing welds. After installing the node partition plates 120, weld the column top sealing plate 160 and the column bottom partition plate 170. The weld of the column top sealing plate 160 is required to be partially penetrated, using a single-sided bevel weld with the bevel facing outwards. The weld of the column bottom process partition plate is required to be a double-sided fillet weld.

[0064] Furthermore, reinforcing plates 111 are installed on both sides of the grouting holes 110 in the node area. The weld of the reinforcing plates 111 is required to be full penetration of the first grade. The column top sealing plate 160 of the circular tube column adopts single-sided bevel welding. The weld is required to be partially penetrated around the perimeter. Considering the need for subsequent end milling, the penetration depth of the column top sealing plate 160 needs to be increased appropriately to avoid appearance defects after end milling.

[0065] In some embodiments of the present invention, the first component unit 200 is assembled separately and then welded to the cylindrical column unit 100 after assembly; the second component unit 300 is installed onto the cylindrical column unit 100 in parts after the first component unit 200 is welded; and the third component unit 400 is assembled separately and then welded to the outer periphery of the cylindrical column unit 100.

[0066] In some embodiments of the present invention, the first component unit 200 includes a side rib plate 210, a panel A220, and a plurality of inner partition plates A230. Two side rib plates 210 are provided and arranged opposite to each other. Both side rib plates 210 are connected to the circular tube column unit 100 and form a wide groove with one side opening with the circular tube column unit 100. The plurality of inner partition plates A230 are spaced apart along the length direction of the wide groove to divide the wide groove into multiple segments. The panel B310 is installed on the open side of the wide groove. Specifically, refer to... Figure 3 , Figure 4 As shown, the four first component units 200 are first welded separately, that is, the side rib plate 210, the panel A220 and the inner partition plate A230 are welded first, and then the side rib plate 210 and the inner partition plate A230 are welded to the circular tube column unit 100.

[0067] In some embodiments of the present invention, the welding method between the first component unit 200 and the circular tube column unit 100 is as follows:

[0068] The main weld between the side rib plate 210 and the panel A220 is performed using backing welding, with a bevel angle of 30° to 35° and a backing gap of 6mm to 8mm. Before welding the side rib plate 210 and the panel A220, a CO2 gas shielded welding root pass should be performed. The inner partition plate A230 is welded on three sides using a root pass welding method, that is, welded to both side rib plates 210 and the panel A220 respectively, and all welds are required to be first-class full penetration. The four corners of the inner partition A230 need to be provided with welding holes with a size of not less than R50 to ensure that the overflow effect of the grouting material in the grouting hole 110 on the circular pipe column unit 100 is not affected after the first component unit 200 is installed on the circular pipe column unit 100. At the same time, in order to control the deformation of the first component unit 200 after welding, it is considered to add a process partition A240 every 2 meters inside the first component unit 200. The weld of the process partition A240 is required to be a fillet weld, and the construction principle is to not affect the grouting effect.

[0069] In some embodiments of the present invention, when the first component unit 200 is installed on the cylindrical tube unit, the installation position of the first component unit 200 should be positioned first, and then the four first component units 200 are welded to the cylindrical tube unit 100 in sequence. Considering the shrinkage in the cross-sectional direction after welding, when positioning the first component unit 200 and the tube wall of the cylindrical tube unit 100, the cross-sectional dimensions need to be controlled with a margin of +3mm on each side. Both side ribs 210 are backed welded to the cylindrical tube unit 100, with a bevel angle of 30° to 35° and a backing gap of 6mm to 8mm; part of the inner partition A230 is welded to the tube wall of the cylindrical tube unit 100, and the welding method is root cleaning welding or backing welding.

[0070] Specifically, the inner partition A230 located at the first and second ends of the wide slot needs to be welded on all four sides. That is, the four edges of the inner partition A230 are welded to the two side ribs 210, the cylindrical tube unit and the panel A220 respectively. The inner partitions at other positions, that is, the inner partitions A230 not located at the ends of the wide slot, basically only have three sides welded. The weld is required to be full penetration of the first level. One edge of the inner partition A230 is only pressed against the cylindrical tube unit but not welded.

[0071] Furthermore, the circular tube column unit 100 has plug weld holes 180 at certain locations for welding the inner partition plate A230 at important stress locations on all four sides. That is, the three edges of the inner partition plate A230 at the plug weld hole 180 are welded to the two side ribs 210 and the panel A220, and are welded to the circular tube column unit 100 through the plug weld holes 180.

[0072] In some embodiments of the present invention, reference is made to... Figure 4 As shown, when welding the first component unit 200, four turning lugs 221 need to be welded on the four panels A220 to assist in the welding of other first component units 200 and subsequent component units; the turning lugs 221 are used to connect the cranes, and the distance between the turning lugs 221 should be no less than 8.5m to ensure the safe distance between the two bridge cranes.

[0073] Reference Figure 5 , Figure 6 As shown, in some embodiments of the present invention, the second component unit 300 includes a panel B310 and a plurality of inner partitions B320. The plurality of inner partitions B320 are spaced apart along the length direction of the narrow slot, and the panel B310 is installed on the opening side of the narrow slot. Specifically, the difference between the second component unit 300 and the first component unit 200 is that the second component unit 300 is not welded together first and then welded to the cylindrical column unit 100. Instead, the inner partitions B320 are welded to the cylindrical column unit 100 after the first component unit 200 has been welded, and then the panel B310 is welded.

[0074] In some embodiments of the present invention, the welding method of the second component unit 300 is as follows:

[0075] First, weld the inner partition plate B320. Multiple inner partition plates B320 are spaced apart along the length of the narrow slot. The welds between the inner partition plate B320 and the pipe wall of the circular column unit 100 and the side rib plate 210 of the first component unit 200 are required to be full penetration of grade I. Welding holes with a size not less than R50 are also required at the four corners of the inner partition plate B320. The three edges of the inner partition plate B320 are welded to the two side rib plates 210 and the pipe wall of the circular column unit 100, respectively. The inner partition plate B320 is not welded to the panel B310. The opposite sides of the panel B310 are welded to the welds of the side rib plate 210 and the panel A220, respectively. Since the joint of the main weld is a double corner joint, a tear-resistant bevel is required. The weld between panel B310 and the first component unit 200 is required to be full penetration of grade I, using backing welding. The backing welding root pass is CO2 gas shielded welding, with a root pass depth of 15mm to 20mm. The bevel angle of the backing weld is 30° to 35°, and the root backing gap is 6mm to 8mm.

[0076] It should be noted that the inner partition plate B320 has two thicknesses: a thick plate and a thin plate. The thick plate is preferably welded using root cleaning, while the thin plate is preferably welded using backing. To control the post-weld deformation of the second component unit 300, a process partition plate B330 is considered to be added every 2 meters inside the narrow slot. The weld of the process partition plate B330 is required to be a fillet weld, and the construction principle is to not affect the grouting effect.

[0077] Reference Figure 7 , Figure 8 As shown, in some embodiments of the present invention, the third component unit 400 includes a corner plate 410, an inner partition plate C420, and a process partition plate C430. The corner plate 410 is installed on the opening side of the narrow slot, the inner partition plate C420 is disposed between the corner plate 410 and the circular tube column unit 100, and the process partition plate C430 is disposed between the corner plate 410 and the panel B310. Specifically, the assembly method of the third component unit 400 is the same as that of the first component unit 200, that is, the third component unit 400 is assembled separately first, and then welded as a whole to the circular tube column unit 100.

[0078] In some embodiments of the present invention, the welding method of the third component unit 400 is as follows:

[0079] First, weld the corner plate 410 and the inner partition plate C420, and the corner plate 410 and the process partition plate C430. The process partition plate C430 is welded to the second end of the corner plate 410, and its size is larger than that of the inner partition plate C420. The welding method of the process partition plate C430 to the corner plate 410 and the inner partition plate C420 to the corner plate 410 is first-level full penetration welding, using root cleaning welding. The welds of the inner partition plate C420 and the process partition plate C430 are required to be fillet welds. The construction principle is to not affect the grouting effect. The size of the through-holes of all inner partition plates C420 and process partition plates C430 is not less than R50.

[0080] In some embodiments of the present invention, when the third component unit 400 is welded to the outer periphery of the cylindrical column unit 100, reference is made to... Figure 9 As shown, for ease of description, the weld seam where one side of the side rib plate 210, one side of the panel A220, and one side of the panel B310 are welded together is positioned as a combined weld seam. Both sides of the corner plate 410 are welded to the combined weld seam. The corner plate 410 and the combined weld seam are welded by a backing weld, with a tear-resistant bevel. The bevel angle is 30° to 35°, and the root backing gap is 6mm to 8mm. The root pass of the backing weld is performed by CO2 gas shielded welding, and the root pass weld depth is 20mm to 25mm.

[0081] In some embodiments of the present invention, only the inner partition C420 or process partition C430 located at the end of the corner plate 410 requires three-sided welding, while the inner partition C420 or process partition C430 at other locations only requires two-sided welding. Taking the inner partition C420 as an example, two-sided welding means that two edges of the inner partition C420 are welded to the two side plates of the corner plate 410 respectively, and the last edge of the inner partition C420 is not welded to the panel A220; three-sided welding means that the three edges of the inner partition C420 are welded to the two side plates of the corner plate 410 and the panel A220 respectively. At this point, the main frame of the support column is basically completed.

[0082] In some embodiments of the present invention, reference is made to... Figures 10 to 12 As shown, after the installation of the third component unit 400 is completed, it is also necessary to assemble loose parts such as studs and steel beam connecting plates on the outer periphery of the support column; the turning lug 221 must be cut off in time, and loading lug and unloading lug must be added at the same time. Note that the weld cut-off position of the turning lug 221 must be ground flat. The welds of the loading lug and unloading lug must be first-class full penetration and can only be handed over after passing the flaw detection.

[0083] In some embodiments of the present invention, reference is made to... Figures 10 to 12 As shown, a column connecting lug 130 is welded to the end of the circular tube column unit 100, a hand hole plate 140 is welded in the field, and a backing plate 150 is welded in the field.

[0084] A method for manufacturing a support column according to a second aspect of the present invention, for manufacturing the above-mentioned support column, includes the following steps:

[0085] S1: Create a cylindrical tube unit 100;

[0086] S2: Assemble multiple first component units 200, and then weld the multiple first component units 200 to the outer periphery of the circular tube column unit 100; the multiple first component units 200 are evenly spaced around the outer periphery of the circular tube column unit 100;

[0088] S4: Assemble multiple third component units 400, and then weld the multiple third component units 400 to the outer periphery of the cylindrical column unit 100.

[0089] The manufacturing method of the support column according to the embodiments of the present invention ensures the welding quality of the components, the continuous and reliable force transmission at the nodes, and the safe and stable process of component manufacturing and hoisting. The support column is decomposed into multiple component units, and the manufacturing of the support column is completed by assembling each component unit and then assembling each component unit in sequence.
